Description

卵殻形状物からの卵殻形状容器の製造方法Method for producing eggshell-shaped container from eggshell-shaped product
 本発明は、例えば料理等の容器となる卵殻形状容器を製造するために用いられる卵殻形状物からの卵殻形状容器の製造方法に関するものである。 (4) The present invention relates to a method for producing an eggshell-shaped container from an eggshell-shaped material used for producing, for example, an eggshell-shaped container serving as a container for cooking or the like.
 従来、この種の卵殻形状物の代表例である鶏卵は、物価の優等生として比較的安価で価格が安定し栄養も豊富であるため、単独で食用に供されるほか、フランス料理、日本料理などの多様な料理文化における料理の素材として極めて有用であり、特に洋菓子店をはじめとする飲食店、マヨネーズの製造工場等で大量に消費されている。そして、その鶏卵の卵液を取り出したあとに残る卵殻の多くは、そのままゴミとして廃棄されたり、まれに白線引きの素材や、菜園の肥料として用いられたりしている。 Conventionally, chicken eggs, which are a typical example of this type of eggshell, are relatively inexpensive, have stable prices, and are rich in nutrients, and are used alone for food, as well as French and Japanese dishes. It is extremely useful as a food ingredient in a variety of cooking cultures, and is consumed in large quantities in restaurants, such as pastry shops, and mayonnaise manufacturing factories. Most of the eggshell remaining after the egg liquid of the chicken egg is removed is discarded as garbage as it is, or is rarely used as white lined material or as fertilizer for vegetable gardens.
 学校教育においても、学校指導要領で「自然環境の保全と科学技術の利用」、「環境に配慮した消費生活の実践」などにより持続可能な社会を形成することは教育上の大命題として明記されているにもかかわらず、家庭科などで使用される卵殻は、そのほとんどがそのまま廃棄されており、理科の植物栽培や、美術科でのエッグアートの素材としての活用はなされておらず、大命題の実践の機会を逸してきた。 In school education, the formation of a sustainable society through “conservation of the natural environment and the use of science and technology” and “practicing environmentally-friendly consumer life” was clearly specified as a major proposition in education. Despite that, most of the eggshells used in home economics are discarded as they are, and they are not used as materials for egg planting in science or plant arts and in art departments. Missed the opportunity to practice.
 卵液を取り出す大量割卵の産業の現場のみならず、ほぼ全ての洋菓子店、料理店など営為の必須の素材であるにも拘らず、卵の殻はその自然の意匠美の価値を見出されることなく、当たり前に廃棄されてきた。卵液を取り出す大量割卵の産業の現場のみならず、ほぼ全ての洋菓子店、料理店など営為の必須の素材であるにも拘らず、卵の殻はその自然の意匠美の価値を見出されることなく、当たり前に廃棄されてきた。 Egg shell can be found not only in the industry of mass egg breaking industry but also in almost all pastry shops, restaurants, etc., but the shell of eggs has the value of its natural design beauty Without being taken for granted. Egg shell can be found not only in the industry of mass egg breaking industry but also in almost all pastry shops, restaurants, etc., but the shell of eggs has the value of its natural design beauty Without being taken for granted.
 しかし、鶏卵の卵殻を容器としての素材として用いることは、これまで廃棄してきたことを社会が認知することとなる。また、卵は自立しないため、フランス料理などにおいてもその有史以来、陶器製や金属製などの「卵立て」を他から調達しなければならなかった。 However, the use of eggshells of chicken eggs as the material for the containers will allow the public to recognize that they have been discarded. Since eggs are not self-supporting, they have had to procure pottery and metal-made "egg-stands" from other sources in French cuisine and other things since its history.
 鶏卵の卵殻から切り取った小片は、蓋として活用されることもなく、そのままゴミとして廃棄されてきたのである。卵殻に関係しなくとも、卵という自然の意匠美をモチーフにした造作物や従来の食品容器は、自然界に還元されにくいガラス製かプラスチック製容器が使われていた。 小 Small pieces cut from the eggshells of chicken eggs were not used as lids and were discarded as garbage. Irrespective of the shell, artifacts and traditional food containers that use the motif of the natural design of eggs as their motifs were made of glass or plastic, which are difficult to return to nature.
 そして従来から、鶏卵の卵殻は、内部から卵黄や卵白を効率良く取りだすことを目的として、種々の装置が提案されている。 Various devices have been proposed for the purpose of efficiently extracting egg yolk and albumen from the inside of egg shells of chicken eggs.
 例えば、特許文献1に開示された卵の殻開装置は、レーザー光線を卵殻の所定の位置に焦点を結んで照射することにより、卵殻膜を残した状態で卵殻を切断して、卵殻が卵液に混入することを防止するとともに、レーザー光線による切断時に生じていた卵白が焦げた特有の周期を防止できる構成としている。 For example, the egg shell opening device disclosed in Patent Document 1 cuts the eggshell while leaving the eggshell membrane by irradiating a laser beam focused on a predetermined position of the eggshell, and the eggshell is converted into egg fluid. In addition, it is configured to prevent mixing of the egg white and the peculiar cycle of the scorched egg white generated at the time of cutting by the laser beam.
 また、特許文献2に開示された卵殻切断装置は、ホルダで卵を頭頂部が上向きになるようにして所定位置に固定し、刃物位置制御用モータで円筒状刃物を卵に向けて上方から下降させ、円筒状刃物を卵の頭頂部に押しあてて回転させ、卵の卵殻の一部を切り開く構成としている。 Further, the eggshell cutting device disclosed in Patent Document 2 fixes the egg at a predetermined position with the holder so that the top of the egg is directed upward, and lowers the cylindrical blade toward the egg with the blade position control motor from above. Then, the cylindrical blade is pressed against the top of the egg and rotated to cut out a part of the egg shell.
 さらに、特許文献3に開示された鶏卵殻切断装置は、鶏卵の鈍端部を上に向けた状態で鶏卵固定具にて固定し、切断機固定機構にて上下動させて切断チップを鶏の鈍端部に当接させた状態で超音波切断機を固定してから、超音波切断機の超音波振動子から超音波振動を切断チップに伝達して鶏卵の鈍端部を切断する構成としている。 Further, the chicken eggshell cutting device disclosed in Patent Document 3 fixes the eggs with a chicken egg fixing tool with the blunt end of the eggs facing upward, and moves the cutting chips up and down by a cutting machine fixing mechanism to cut the cutting chips of the chickens. After fixing the ultrasonic cutting machine in a state where it is in contact with the blunt end, the ultrasonic vibration from the ultrasonic vibrator of the ultrasonic cutting machine is transmitted to the cutting tip to cut the blunt end of the egg I have.

 G7の海洋プラスチック憲章で、その政策が国際課題になっているにも関わらず、上述の如く、従来、鶏卵の卵殻の利用は限定的であり、卵殻は有効利用されずに廃棄されることが多かった。また、食品等を入れる容器としては、自然界に還元され難いガラス製やプラスチック製の容器が多く、卵の殻が容器等として利用される例は殆どない。 Although the G7 Marine Plastics Charter states that its policy has become an international issue, as described above, the use of eggshells in chicken eggs has been limited, and eggshells may be discarded without being used effectively. There were many. In addition, as containers for holding foods and the like, there are many containers made of glass or plastic which are hardly reduced to the natural world, and there are almost no cases where egg shells are used as containers or the like.
 卵殻を容器等として利用するためには、卵殻の脆弱性が問題となる。特に、卵殻の一部を切り取る際の切り方によっては、切り取った開口縁にバリが発生した場合に非常に脆弱になってしまう。また、容器としての卵殻が割れてしまうと、見た目はもとより、内容物の漏れや外気との接触による内容物の品質劣化等が生ずる。また、生卵の卵殻から安定した容器を創造することを一例に取れば、如何に綺麗に切削したとしても、天然の気孔を有しており、その切削断面の凹凸をコーティングして強化する必要がある。よって、卵殻を各種用途の容器等として繰り返し有効的に利用するためには、卵殻の強度および耐久性を高めることが求められる。 脆弱 In order to use eggshells as containers, etc., the vulnerability of eggshells becomes a problem. In particular, depending on how to cut off a part of the eggshell, it becomes very vulnerable when burrs are generated at the cut edge of the opening. Further, if the eggshell as a container is broken, not only the appearance but also the quality of the contents is deteriorated due to leakage of the contents or contact with the outside air. Also, for example, to create a stable container from eggshells of raw eggs, no matter how finely cut, it has natural pores and it is necessary to coat and strengthen the unevenness of the cut cross section There is. Therefore, in order to use the eggshell repeatedly and effectively as containers for various uses, it is required to increase the strength and durability of the eggshell.
 さらに、特許文献1に開示された卵の殻開装置によれば、レーザー光線を用いていることから、レーザー光線を発生させる装置が必要となり、装置が大型になってしまう。また、特許文献2に開示された卵殻切断装置においても、卵を頭頂部が上向きになるようにして所定位置に固定するホルダや、円筒状刃物を卵に向けて上方から下降させる刃物位置制御用モータを有する構成であるため、装置が大型である。さらに、特許文献3に開示された鶏卵殻切断装置では、鶏卵の鈍端部を上に向けた状態で固定する鶏卵固定具や、切断チップを鶏の鈍端部に当接させるための上下動可能な切断機固定機構を有することから、装置が大型となっている。 Furthermore, according to the egg shell opening device disclosed in Patent Document 1, since a laser beam is used, a device for generating a laser beam is required, and the device becomes large. Also, in the eggshell cutting device disclosed in Patent Document 2, a holder for fixing the egg at a predetermined position with the top of the egg facing upward, and a tool position control for lowering the cylindrical blade from above toward the egg. Since it has a configuration having a motor, the device is large. Further, in the chicken eggshell cutting device disclosed in Patent Document 3, a chicken egg fixing device for fixing the eggs with the blunt ends thereof facing upward, and a vertical movement for bringing the cutting chips into contact with the blunt ends of the chickens The device is large due to having a possible cutter fixing mechanism.
 いずれにしても、これら特許文献1~3に開示された装置では、卵を開口するための装置に過ぎず、卵を開口した後に容器として用いることを前提としたものでない。また、これら装置は、いずれも大型であることから、これら装置を導入するためのスペースの確保が必要であり、気軽に使用することが容易でない。したがって、例えば飲食店や家庭等で気軽に卵殻の一部を開口して容器として用いることは容易ではなく、使い勝手が良くない。また、一部を円形状に切り取った卵殻等の卵殻形状物の開口部を上に向けた状態で自立させることは容易ではないという問題があった。 In any case, the devices disclosed in Patent Documents 1 to 3 are merely devices for opening eggs, and are not intended to be used as containers after the eggs are opened. In addition, since these devices are all large, it is necessary to secure a space for introducing these devices, and it is not easy to use them casually. Therefore, it is not easy to easily open a part of the eggshell and use it as a container, for example, in a restaurant or at home, which is not convenient. In addition, there is a problem that it is not easy to stand alone with the opening of an eggshell-shaped object such as an eggshell partially cut into a circular shape facing upward.
 本発明は、このような従来技術の実情に鑑みてなされたもので、その目的は、一部を円形状に切り取った卵殻等の卵殻形状物の開口部を上に向けた状態で自立させることは容易ではないため、卵殻形状物からの自立が容易な卵殻形状容器の製造方法を提供することにある。 The present invention has been made in view of such a situation of the related art, and an object of the present invention is to make the eggshell-shaped object such as an eggshell partially cut into a circular shape stand alone with its opening facing upward. The object of the present invention is to provide a method for manufacturing an eggshell-shaped container that is easy to stand up from an eggshell-shaped material because it is not easy.
 上記の目的を達成するために、本発明の卵殻形状容器の製造方法は、卵殻形状物の一部を切り取ることにより、一部が切り取られた本体部と、前記卵殻形状物から切り取った台座本体とを形成する工程と、前記台座本体の一部を切り取ることにより、一部が切り取られた台座部を形成する工程と、前記台座部の小径側の切り取った側を上側に向けた状態とし、前記本体部の切り取られた側を上側に向けて前記台座部上に載置させる工程と、を備えることを特徴としている。 In order to achieve the above object, a method for producing an eggshell-shaped container according to the present invention is characterized in that a part of the eggshell-shaped material is cut off, and a part of the main body is cut off, and a pedestal body cut out from the eggshell-shaped material. And forming a part of the pedestal main body by cutting off a part of the pedestal body, and forming a part of the pedestal part cut off, with the cut side of the small diameter side of the pedestal part facing upward, Mounting the main body on the pedestal with the cut side of the main body facing upward.
 このように構成された卵殻形状容器の製造方法では、台座部の小径側の切り取った側を上側に向けた状態とし、本体部の切り取られた側を上側に向けて台座部上に載置させた卵殻形状容器としていることから、一つの卵殻形状物から卵殻形状容器を製造でき、切り取った側を上側に向けた状態の本体部を台座部にて支持させて自立させることができる。よって、一つの卵殻形状物から製造された卵殻形状容器を、例えば、料理用容器や園芸用容器等といった種々の用途に容易に用いることができる。 In the method for manufacturing an eggshell-shaped container configured as described above, the cut side of the small diameter side of the pedestal portion is placed on the upper side, and the cut side of the main body is placed on the pedestal portion with the cut side facing upward. Since the eggshell-shaped container is used, the eggshell-shaped container can be manufactured from one eggshell-shaped product, and the main body with the cut side facing upward can be supported by the pedestal portion to be self-standing. Therefore, the eggshell-shaped container manufactured from one eggshell-shaped product can be easily used for various uses such as a cooking container and a gardening container.
 また、本発明の卵殻形状容器の製造方法は、卵殻形状物の一部を円形状に切り取りとって、一部が切り取られた卵殻形状容器を形成する工程と、前記卵殻形状物の切り取った部分から所定の間隔を空けて円形状に切り取って、一部が切り取られた本体部と、前記卵殻形状物から切り取った略円環状の台座部とを形成する工程と、前記台座部の小径側の切り取った側を上側に向けた状態とし、前記本体部の切り取られた側を上側に向けて前記台座部上に載置させる工程と、を備えることを特徴としている。 Further, the method for manufacturing an eggshell-shaped container of the present invention comprises the steps of cutting a part of the eggshell-shaped object into a circular shape to form a partially cut eggshell-shaped container, and cutting the eggshell-shaped object. Forming a main body part cut away from the eggshell-shaped object and a substantially annular pedestal part cut out from the eggshell-shaped object, and a small-diameter side of the pedestal part. Setting the cut side to the upper side, and placing the main body on the base with the cut side to the upper side.
 このように構成された卵殻形状容器の製造方法では、台座部の小径側の切り取った側を上側に向けた状態とし、本体部の切り取られた側を上側に向けて台座部上に載置させた卵殻形状容器としていることから、一つの卵殻形状物から卵殻形状容器を製造でき、切り取った側を上側に向けた状態の本体部を台座部にて支持させて自立させることができる。よって、一つの卵殻形状物から製造された卵殻形状容器を、例えば、料理用容器や園芸用容器等といった種々の用途に容易に用いることができる。 In the method for manufacturing an eggshell-shaped container configured as described above, the cut side of the small diameter side of the pedestal portion is placed on the upper side, and the cut side of the main body is placed on the pedestal portion with the cut side facing upward. Since the eggshell-shaped container is used, the eggshell-shaped container can be manufactured from one eggshell-shaped product, and the main body with the cut side facing upward can be supported by the pedestal portion to be self-standing. Therefore, the eggshell-shaped container manufactured from one eggshell-shaped product can be easily used for various uses such as a cooking container and a gardening container.
 さらに、切削装置は、卵殻形状物の一部を切り取って開口部を形成するための切削装置であって、作業者が把持する把持本体と、前記把持本体に設けられた略筒状の切削刃本体と、前記切削刃本体を超音波振動させる超音波発生装置と、を備え、前記切削刃本体は、周方向に連続する刃面を有することを特徴としている。 Further, the cutting device is a cutting device for cutting off a part of the eggshell-shaped object to form an opening, and includes a grip body that is gripped by an operator, and a substantially cylindrical cutting blade provided on the grip body. It is provided with a main body and an ultrasonic generator for ultrasonically vibrating the cutting blade main body, wherein the cutting blade main body has a blade surface continuous in a circumferential direction.
 このように構成された切削装置では、超音波発生装置にて切削刃本体を超音波振動させた状態とし、作業者が把持本体を把持して切削刃本体の刃面を卵殻形状物に押し当てて食い込ませることにより、卵殻形状物のうちの切削刃本体の刃面を押し当てた部分を切り取って開口部を形成することができる。したがって、例えば飲食店や家庭等であっても、作業者が把持本体を把持して切削刃本体を押し当てるという簡単な作業で、卵殻形状物を開口できるから、一部を開口した卵殻形状物を気軽に容器として用いることができる。このため、卵殻形状物を開口して容器として用いるための切削装置の使い勝手を向上できる。 In the cutting device configured as described above, the cutting blade body is ultrasonically vibrated by the ultrasonic generator, and the operator grips the gripping body and presses the blade surface of the cutting blade body against the eggshell-shaped object. By making a cut, the portion of the eggshell-shaped article against which the cutting surface of the cutting blade body is pressed can be cut out to form an opening. Therefore, even in a restaurant or a home, for example, an egg shell-shaped object can be opened by a simple operation in which an operator grips a gripping body and presses a cutting blade body, so that an egg shell-shaped object partially opened. Can be easily used as a container. For this reason, the usability of the cutting device for opening the eggshell-shaped object and using it as a container can be improved.
 この場合において、前記刃面は、前記切削刃本体の外周側に設けられているため、切削刃本体の刃面を卵殻形状物に食い込ませた際に生じる切削屑を、切削刃本体の外周側に生じさせることができる。よって、卵殻形状物を開口する際における卵殻形状物の内部への切削屑の侵入を防止できるため、開口部の形成後における卵殻形状物の内部から切削屑を取り除く作業を簡略化でき、例えば卵殻形状物が鶏卵の場合における、卵黄および卵白の利用を容易にできる。 In this case, since the blade surface is provided on the outer peripheral side of the cutting blade main body, cutting debris generated when the blade surface of the cutting blade main body bites into the eggshell-shaped object, the outer peripheral side of the cutting blade main body. Can be caused. Therefore, since cutting chips can be prevented from entering the inside of the eggshell-shaped object when the eggshell-shaped object is opened, the operation of removing the chips from the inside of the eggshell-shaped object after the formation of the opening can be simplified. The use of egg yolk and egg white when the shape is a chicken egg can be facilitated.
 また、この場合において、前記切削刃本体は、前記刃面の根元側に連続する薄肉状の逃げ部を有することから、切削刃本体の刃面を卵殻形状物に食い込ませた際に、この卵殻形状物への切削刃本体の刃面からの衝撃や応力を逃げ部へ逃がすことができる。よって、卵殻形状物の開口部分等におけるひび割れの発生を抑制できるため、卵殻形状物に開口部を形成する作業をより精度良く容易にできる。 Further, in this case, since the cutting blade body has a continuous thin-walled relief portion at the root side of the blade surface, when the blade surface of the cutting blade body is cut into the eggshell-shaped object, the eggshell is cut. Shock and stress from the blade surface of the cutting blade body to the shaped object can be released to the relief portion. Therefore, the occurrence of cracks in the opening portion of the eggshell-shaped object can be suppressed, so that the operation of forming the opening in the eggshell-shaped object can be more accurately and easily performed.
 また、この場合において、前記切削刃本体を複数備え、前記複数の切削刃本体は、異なる外径寸法に形成されていることから、例えば、外径寸法が大きな切削刃本体の刃面を卵殻形状物に押し当てて開口してから、この切り取った卵殻形状物の一部の中心位置に、外径寸法の小さな切削刃本体の刃面を押し当てて開口することにより、卵殻形状物から円環状に切り取った台座状の部分を設けることができる。したがって、外径寸法の異なる切削刃本体を有した複数の切削装置を用いることなく、1台の切削装置のみで、卵殻形状物から円環状に切り取った台座状の部分を設けることができるので、切削装置の使い勝手を向上できる。 Further, in this case, since the plurality of cutting blade bodies are provided, and the plurality of cutting blade bodies are formed with different outer diameters, for example, the blade surface of the cutting blade body having a larger outer diameter has an eggshell shape. By pressing against the object and opening, and pressing the blade surface of the cutting blade body with a small outer diameter at the center position of a part of the cut eggshell-shaped object to open it, the eggshell-shaped object is annular. A pedestal-shaped portion can be provided. Therefore, it is possible to provide a pedestal-shaped portion cut out from an eggshell-shaped object in an annular shape with only one cutting device without using a plurality of cutting devices having cutting blade bodies having different outer diameters. Usability of the cutting device can be improved.
 また、この場合において、前記卵殻形状物の長軸方向を上下方向に向けて保持する保持具を備えるため、保持具にて卵殻形状物の長軸方向を上下方向に向けて保持することにより卵殻形状物を位置決めできるので、例えば卵殻形状物の頭頂部等の所定位置への切削刃本体の刃面の押し当てを精度良く正確に行うことができるから、卵殻形状物に開口部を形成する作業を精度良く行うことができる。 Further, in this case, in order to provide a holder for holding the longitudinal direction of the eggshell-shaped object in the vertical direction, the eggshell is held by holding the eggshell-shaped object in the vertical direction with the holder. Since the shaped object can be positioned, for example, the blade surface of the cutting blade body can be accurately and accurately pressed to a predetermined position such as the top of the eggshell-shaped object, so that an operation of forming an opening in the eggshell-shaped object Can be performed with high accuracy.
 さらに、切削装置は、複数の卵殻形状物の一部を切り取って開口部を形成するための切削装置であって、周方向に連続する刃面を有する筒状の切削刃本体を複数有し、これら複数の切削刃本体が軸方向を平行にして並べて配置された切削刃群と、前記切削刃群の前記複数の切削刃本体すべてを超音波振動させる超音波発生装置と、を備えたことを特徴としている。 Further, the cutting device is a cutting device for cutting a part of the plurality of eggshell-shaped objects to form an opening, and has a plurality of cylindrical cutting blade main bodies having blade surfaces continuous in the circumferential direction, A cutting blade group in which the plurality of cutting blade bodies are arranged in parallel with each other in an axial direction, and an ultrasonic generator that ultrasonically vibrates all of the plurality of cutting blade bodies in the cutting blade group. Features.
 このように構成された切削装置では、切削刃群の複数の切削刃本体のすべてを超音波振動させ、これら複数の切削刃本体の刃面それぞれを複数の卵殻形状物のいずれかに押し当てて食い込ませる等することにより、これら複数の卵殻形状物のすべてを同時に開口できる。したがって、一度の超音波発生装置からの各切削刃本体への超音波振動によって、複数の卵殻形状物それぞれに開口部を形成できるから、複数の卵殻形状物の開口作業を容易にできる。このことから、複数の卵殻形状物を開口するための切削装置の使い勝手を向上できる。 In the cutting device configured as described above, all of the plurality of cutting blade bodies of the cutting blade group are ultrasonically vibrated, and the blade surfaces of the plurality of cutting blade bodies are pressed against any of the plurality of eggshell-shaped objects. It is possible to open all of the plurality of eggshell-shaped objects at the same time by biting them. Therefore, the opening can be formed in each of the plurality of eggshell-shaped objects by the ultrasonic vibration from the ultrasonic generator to each of the cutting blade main bodies, so that the opening operation of the plurality of eggshell-shaped objects can be facilitated. From this, the usability of the cutting device for opening a plurality of eggshell-shaped objects can be improved.
 また、この場合においては、複数の卵殻形状物を並べて保持する保持装置を備え、前記複数の切削刃本体は、前記保持装置に保持された複数の卵殻形状物に対向する位置に配置されているため、複数の切削刃本体を超音波振動させ、これら複数の切削刃本体の刃面のそれぞれを、対向して位置する卵殻形状物に押し当てて食い込ませる等することにより、保持装置にて保持されている複数の卵殻形状物のそれぞれを同時に開口できるから、複数の卵殻形状物の開口作業を精度良く容易に行うことができる。 In this case, a holding device is provided for holding a plurality of eggshell-shaped objects side by side, and the plurality of cutting blade bodies are arranged at positions facing the plurality of eggshell-shaped objects held by the holding device. For this reason, the plurality of cutting blade bodies are ultrasonically vibrated, and each of the blade surfaces of the plurality of cutting blade bodies is pressed against and bites into an eggshell-shaped object positioned opposite thereto, thereby being held by the holding device. Since the plurality of eggshell-shaped objects can be simultaneously opened, it is possible to easily and accurately open the eggshell-shaped objects.
 さらに、切削装置は、卵殻形状物の一部を切り取って開口部を形成するための切削装置であって、作業者が把持する把持本体と、前記把持本体に周方向に回転可能に取り付けられた円筒状の切削刃本体と、前記把持本体に設けられ、前記切削刃本体を回転駆動させるモータと、を備え、前記切削刃本体は、周方向に連続する刃面を有することを特徴としている。 Further, the cutting device is a cutting device for cutting off a part of the eggshell-shaped object to form an opening, and is attached to the grip main body to be gripped by an operator and to the grip main body so as to be rotatable in a circumferential direction. It is provided with a cylindrical cutting blade main body, and a motor provided on the gripping main body to rotationally drive the cutting blade main body, wherein the cutting blade main body has a blade surface continuous in a circumferential direction.
 このように構成された切削装置では、作業者が把持本体を把持して切削刃本体の刃先を卵殻形状物に押し当て、モータにて切削刃本体を回転駆動させることにより、卵殻形状物のうちの切削刃本体の刃先を押し当てた部分を切り取って開口部を形成することができる。したがって、例えば飲食店や家庭等であっても、作業者が把持本体を把持した状態で切削刃本体を卵殻形状物に押し当てるという簡単な作業で、卵殻形状物に開口部を形成できるから、一部を開口した卵殻形状物を気軽に容器として用いることができる。このため、卵殻形状物を開口して容器として用いるための切削装置の使い勝手を向上できる。 In the cutting device configured as described above, the operator grips the gripping body, presses the cutting edge of the cutting blade body against the eggshell-shaped object, and rotates the cutting blade body with a motor to rotate the cutting blade body. An opening can be formed by cutting off a portion of the cutting blade body against which the cutting edge is pressed. Therefore, for example, even in a restaurant or a home, the worker can press the cutting blade body against the eggshell-shaped object while holding the gripping body, since the opening can be formed in the eggshell-shaped object, An egg shell-shaped product with a part opened can be used easily as a container. For this reason, the usability of the cutting device for opening the eggshell-shaped object and using it as a container can be improved.
 また、この構成において、前記切削刃本体での切削時に生じる前記卵殻形状物の切削片を吸気する吸気機構を備えたため、切削刃本体にて卵殻形状物を切削する時に生じ得る卵殻形状物内への切削片の侵入を防止できる。したがって、例えば卵殻形状物が鶏卵の場合における、内容物、すなわち卵黄および卵白への鶏卵の切削片の混入を防止できるから、これら卵黄および卵白の利用が容易にできる。 Further, in this configuration, since the air intake mechanism for inhaling the cut piece of the eggshell-shaped object generated at the time of cutting with the cutting blade body is provided, the inside of the eggshell-shaped object that may be generated when cutting the eggshell-shaped object with the cutting blade body is provided. Of cutting pieces can be prevented. Therefore, for example, in the case where the egg shell-shaped material is a chicken egg, it is possible to prevent the cut pieces of the chicken egg from being mixed into the contents, that is, the egg yolk and the albumen, and the egg yolk and the albumen can be easily used.
 また、この場合において、前記切削刃本体が前記卵殻形状物から受ける反力を感知する圧力感知装置を備えたため、切削刃本体にて卵殻形状物を切削する時に生じ得る卵殻形状物のつぶれや破損を適切に防止できる。 Further, in this case, since the cutting blade body is provided with a pressure sensing device for sensing a reaction force received from the eggshell-shaped object, the eggshell-shaped object may be crushed or damaged when the eggshell-shaped object is cut by the cutting blade body. Can be appropriately prevented.
 また、この構成において、前記切削刃本体に対する前記卵殻形状物の向きを検出する向き検出装置を備えたため、切削刃本体を卵殻形状物に押し当てた際における卵殻形状物の向きを精度良く合わせることができるから、卵殻形状物に開口部を形成する際の位置合わせを容易にできる。したがって、卵殻形状物に開口部を形成する作業を精度良く容易に行うことができる。 In addition, in this configuration, since the direction detecting device that detects the direction of the eggshell-shaped object with respect to the cutting blade body is provided, the direction of the eggshell-shaped object when the cutting blade body is pressed against the eggshell-shaped object can be accurately adjusted. Therefore, the positioning at the time of forming the opening in the eggshell-shaped object can be facilitated. Therefore, the operation of forming the opening in the eggshell-shaped object can be easily and accurately performed.
 また、この構成において、前記切削刃本体に対する前記卵殻形状物の基準位置を位置決めする位置決め機構を備えたため、切削刃本体を卵殻形状物に押し当てた際における卵殻形状物の基準位置の位置合わせを精度良く容易にできる。よって、卵殻形状物に開口部を形成する作業を容易に精度良く行うことができる。 Further, in this configuration, since the positioning mechanism for positioning the reference position of the eggshell-shaped object with respect to the cutting blade body is provided, alignment of the reference position of the eggshell-shaped object when the cutting blade body is pressed against the eggshell-shaped object is performed. Easy and accurate. Therefore, the operation of forming the opening in the eggshell-shaped object can be easily and accurately performed.
 また、この構成において、前記切削刃本体を複数備え、前記複数の切削刃本体は、それぞれの刃面の外径寸法が異なり、前記把持本体に同心状に回転可能に取り付けられていることから、複数の切削刃本体の外形寸法が異なるそれぞれの刃面に合致した大きさの開口部を卵殻形状物に形成することができる。したがって、例えば大きな外径寸法の刃面を卵殻形状物に押し当てて開口部を形成してから、この切り取った側の卵殻形状物の一部の中心位置に、小さな外径寸法の刃面を押し当てて切り取って開口部を形成することにより、卵殻形状物から円環状に切り取った台座状の部分を製造できる。したがって、外径寸法の異なる刃面を有する複数台の切削装置を用いることなく、1台の切削装置のみで、卵殻形状物から円環状に切り取った台座状の部分を製造することができる。 Further, in this configuration, since a plurality of the cutting blade main bodies are provided, and the plurality of cutting blade main bodies have different outer diameters of respective blade surfaces, and are rotatably mounted concentrically on the grip main body, An opening having a size corresponding to each blade surface of the plurality of cutting blade bodies having different outer dimensions can be formed in the eggshell-shaped object. Therefore, for example, after a blade surface having a large outer diameter is pressed against an eggshell-shaped object to form an opening, a blade surface having a small outer diameter is placed at a central position of a part of the eggshell-shaped material on the cut side. By pressing and cutting to form an opening, a pedestal-shaped portion cut in an annular shape from an eggshell-shaped product can be manufactured. Therefore, a pedestal-shaped portion cut out in an annular shape from an eggshell-shaped product can be manufactured with only one cutting device without using a plurality of cutting devices having blade surfaces with different outer diameters.
 さらに、切削装置は、複数の卵殻形状物それぞれの一部を切り取って開口部を形成するための切削装置であって、周方向に連続する刃面を有する複数の円筒状の切削刃本体を備え、これら複数の切削刃本体それぞれの前記刃面が設けられた側を同一方向に向けかつ軸方向を平行にした状態で、前記複数の切削刃本体それぞれを周方向に回転可能に並べて配置された切削刃群と、前記切削刃群の前記複数の切削刃本体のそれぞれを回転駆動させるモータと、を具備したことを特徴としている。 Further, the cutting device is a cutting device for forming an opening by cutting a part of each of the plurality of eggshell-shaped objects, and includes a plurality of cylindrical cutting blade main bodies having a circumferentially continuous blade surface. The plurality of cutting blade bodies are arranged so as to be rotatable in the circumferential direction, with the sides on which the blade surfaces of the plurality of cutting blade bodies are provided facing in the same direction and the axial directions are parallel. It is characterized by comprising a cutting blade group, and a motor for rotating and driving each of the plurality of cutting blade bodies of the cutting blade group.
 このように構成された切削装置では、切削機群の複数の切削刃本体の刃面のそれぞれを複数の卵殻形状物に押し当てた状態とし、これら複数の切削刃本体をモータにて回転駆動させることにより、これら複数の卵殻形状物のすべてに開口部を形成することができる。したがって、モータによる各切削刃本体の一度の回転駆動によって、複数の卵殻形状物それぞれに開口部を形成することができるから、複数の卵殻形状物の開口作業を容易に行うことができる。このため、複数の卵殻形状物に開口部を形成するための切削装置の使い勝手を向上することができる。 In the cutting device configured as described above, each of the blade surfaces of the plurality of cutting blade bodies of the cutting machine group is pressed against the plurality of eggshell-shaped objects, and the plurality of cutting blade bodies are rotationally driven by the motor. Thus, openings can be formed in all of the plurality of eggshell-shaped objects. Therefore, the opening can be formed in each of the plurality of eggshell-shaped objects by a single rotation drive of each cutting blade body by the motor, so that the opening operation of the plurality of eggshell-shaped objects can be easily performed. Therefore, the usability of the cutting device for forming the openings in the plurality of eggshell-shaped objects can be improved.
 さらに、補強材は、卵殻形状物を補強するための補強材であって、前記卵殻形状物の少なくとも一部に積層され可食性の水溶性物質を主成分とする第1の層と、前記第1の層上に積層され可食性の熱可塑性物質を主成分とする第2の層と、を備えたことを特徴としている。 Further, the reinforcing material is a reinforcing material for reinforcing the eggshell-shaped object, wherein the first layer is laminated on at least a part of the eggshell-shaped object and mainly includes an edible water-soluble substance; And a second layer mainly composed of an edible thermoplastic and laminated on the first layer.
 このように構成された補強材では、可食性の水溶性物質を主成分とする第1の層を卵殻形状物の少なくとも一部に積層させて乾燥させてから、この第1の層上に可食性の熱可塑性物質を主成分とする第2の層を積層させて加熱して硬化させることにより、例えば卵殻等の一部を切り取ると強度が極端に低下する卵殻形状物であっても強固に補強できるとともに、卵殻形状物を食品の容器等として用いた場合に、誤って口を付けてしまった際の人的被害を防止できる。また同時に、表面に水が付着した場合における第1の層の溶け出しを第2の層にて防止できる。 In the reinforcing material configured as described above, the first layer mainly composed of an edible water-soluble substance is laminated on at least a part of the eggshell-shaped material, dried, and then placed on the first layer. By laminating and heating and curing the second layer mainly composed of an edible thermoplastic substance, for example, an eggshell-shaped material whose strength is extremely reduced when a part of the eggshell or the like is extremely cut off is firmly fixed. In addition to being able to reinforce, when the eggshell-shaped article is used as a food container or the like, it is possible to prevent human damage when the mouth is accidentally put on. At the same time, the second layer can prevent the first layer from dissolving when water adheres to the surface.
 また、この構成において、前記水溶性物質は、プルランであるため、卵殻形状物に対する第1の層の付着性や被膜性を向上することができる。 In addition, in this configuration, since the water-soluble substance is pullulan, it is possible to improve the adhesiveness and coating property of the first layer on the eggshell-shaped material.
 また、この場合において、前記第1の層は、水と前記プルランとを含有し、前記プルランの含有率は、前記水に対し12.5重量%以上17.5重量%以下である。すなわち、水に対するプルランの含有率を17.5重量%より高くすると、卵殻形状物に対するプルランの付着量が多くなり過ぎ、卵殻形状物の付着面に第1の層の液だまりができやすく乾燥時間が長くなってしまう。一方、水に対するプルランの含有率を12.5重量%より低くすると、卵殻形状物に対するプルランの付着性が低下してしまい、卵殻形状物から第1の層が剥がれやすくなってしまう。したがって、卵殻形状物に対する付着性および乾燥時間の観点から、水に対するプルランの含有率は12.5重量%以上17.5重量%以下が好ましい。 In this case, the first layer contains water and the pullulan, and the content of the pullulan is 12.5% by weight or more and 17.5% by weight or less based on the water. That is, when the content of pullulan in water is higher than 17.5% by weight, the amount of pullulan adhered to the egg-shell-shaped material becomes too large, so that the first layer is easily pooled on the adhered surface of the egg-shell-shaped material, and the drying time is increased. Becomes longer. On the other hand, if the content of pullulan in water is lower than 12.5% by weight, the adhesion of the pullulan to the eggshell-shaped material is reduced, and the first layer is easily peeled from the eggshell-shaped material. Accordingly, the content of pullulan in water is preferably 12.5% by weight or more and 17.5% by weight or less from the viewpoints of adhesion to eggshell-shaped material and drying time.
 また、この場合において、前記第1の層は、水と前記プルランとを含有し、前記プルランの含有率は、前記水に対し15重量%である。すなわち、水に対するプルランの含有率を15重量%とすると、卵殻形状物に対して適切な付着性を確保でき比較的短時間で乾燥できるから、特に好ましい。 In this case, the first layer contains water and the pullulan, and the content of the pullulan is 15% by weight based on the water. That is, when the content of pullulan with respect to water is set to 15% by weight, it is particularly preferable since appropriate adhesion to the eggshell-shaped material can be secured and drying can be performed in a relatively short time.
 また、この場合において、前記熱可塑性物質は、シェラックであるため、アルコール系溶液のみに溶ける性質を有していることから、表面に水が付着した場合における第1の層の溶け出しを適切に防止できる。 Further, in this case, since the thermoplastic substance is shellac, it has a property of being dissolved only in an alcohol-based solution, so that the first layer can be appropriately dissolved when water adheres to the surface. Can be prevented.

[卵殻および容器]
 以下、本発明の実施形態に係る卵殻形状物およびそれを用いた卵殻形状容器について図面に基づいて詳細に説明する。
[Eggshell and container]
Hereinafter, an eggshell-shaped product and an eggshell-shaped container using the same according to an embodiment of the present invention will be described in detail with reference to the drawings.
 図1は、卵殻形状物としての卵殻20にて形成された容器10を示す斜視図である。容器10は、例えば、フランス料理、日本料理などの多様な料理文化における料理用の容器や、洋菓子等の食品用の容器、植物栽培用のポット、微生物や細胞等を培養するための培地用シャーレ、ローソク用の容器、エッグアート用の素材、小物入れ等の日用品等として用いられる卵殻形状容器である。図1に示すように、容器10は、内容物が充填される本体部11と、本体部11を支える台座部12と、を有する。 FIG. 1 is a perspective view showing a container 10 formed of an eggshell 20 as an eggshell-shaped object. The container 10 is, for example, a container for cooking in various cooking cultures such as French cuisine and Japanese cuisine, a container for food such as Western confectionery, a pot for plant cultivation, a petri dish for culture of microorganisms and cells and the like. This is an eggshell-shaped container used as a container for candles, a material for egg art, a daily necessity such as an accessory case, and the like. As shown in FIG. 1, the container 10 has a main body 11 into which contents are filled, and a pedestal 12 supporting the main body 11.
 本体部11および台座部12は、鶏卵等の殻である卵殻20を切断して得られた卵殻21および卵殻22にて形成されている。容器10の基本的な形状は、素材としての卵殻20の形状をそのまま利用したものであり、容器10には、自然の造形美を活かした意匠が表現されている。なお、ここでは容器10の素材として卵殻20を用いているが、卵殻20以外の卵殻形状をしたその他の中空な卵殻形状物であっても良い。 The main body 11 and the pedestal 12 are formed of an eggshell 21 and an eggshell 22 obtained by cutting an eggshell 20 which is a shell such as a chicken egg. The basic shape of the container 10 uses the shape of the eggshell 20 as a raw material as it is, and the container 10 expresses a design that makes use of the beauty of natural modeling. Here, the eggshell 20 is used as a material of the container 10, but other eggshell-shaped hollow eggshell-shaped materials other than the eggshell 20 may be used.
 図2(A)は、容器10の平面図である。図2(B)は、容器10の縦断面図であり、図2(A)に示すA-A線に沿った断面を示している。図2(C)は、容器10の底面図である。図2(A)および図2(B)に示すように、本体部11は、一部が円形状に切り取られて切除されて開口された卵殻21から構成されており、略カップ状の形態を成す。本体部11の上部には、平面視略円形状の開口部14が形成されている。 FIG. 2A is a plan view of the container 10. FIG. 2B is a vertical cross-sectional view of the container 10 and shows a cross section taken along the line AA shown in FIG. FIG. 2C is a bottom view of the container 10. As shown in FIGS. 2 (A) and 2 (B), the main body 11 is formed of an eggshell 21 which is partially cut into a circular shape and cut and opened, and has a substantially cup-like shape. Make. An opening 14 having a substantially circular shape in plan view is formed in an upper part of the main body 11.
 図2(B)および図2(C)に示すように、台座部12は、卵殻22から形成され、略リング状に形成されている。具体的に、台座部12は、下部の外径寸法よりも上部の外径寸法が小さく、略円錐台状の筒状に形成されている。台座部12の上部に形成された開口部15の径寸法は、本体部11の長軸方向に直交する最大径寸法より小さい。開口部14を上側に向けた状態で本体部11の下部を台座部12の開口部15に挿入させて載置させることにより、本体部11は、台座部12の上部に支持される。すなわち、台座部12は、本体部11を自立させるために用いられる自立リングとしての機能を有している。 台 As shown in FIGS. 2B and 2C, the pedestal portion 12 is formed from an eggshell 22, and is formed in a substantially ring shape. Specifically, the pedestal portion 12 has an upper outer diameter smaller than a lower outer diameter, and is formed in a substantially frustoconical cylindrical shape. The diameter of the opening 15 formed in the upper portion of the pedestal 12 is smaller than the maximum diameter orthogonal to the long axis direction of the main body 11. By inserting the lower part of the main body 11 into the opening 15 of the pedestal part 12 and placing the lower part with the opening 14 facing upward, the main body 11 is supported on the upper part of the pedestal part 12. That is, the pedestal portion 12 has a function as a self-standing ring used to make the main body portion 11 self-standing.
 図3は、コーティング後の容器10の縦方向断面図を示している。図3に示すように、卵殻21の外表面21a、および切断された開口部14の端面21cは、卵殻21を補強するための補強材となるコーティング層16にて覆われている。これにより、卵殻21の強度および耐久性が高められ、本体部11の抗菌性が高められる。 FIG. 3 shows a longitudinal sectional view of the container 10 after coating. As shown in FIG. 3, the outer surface 21 a of the eggshell 21 and the end surface 21 c of the cut opening 14 are covered with a coating layer 16 serving as a reinforcing material for reinforcing the eggshell 21. Thereby, the strength and durability of the eggshell 21 are enhanced, and the antibacterial property of the main body 11 is enhanced.
 ここで、コーティング層16は、卵殻21の外表面21aおよび端面21cに被覆されて固着しており、卵殻21の気孔に入り込んでいる。すなわち、卵殻21の気孔は、コーティング層16によって覆われて塞がれている。これにより、コーティング層16で覆われた卵殻21は、気孔が塞がれる状態となることから優れた強度が得られる。 Here, the coating layer 16 is coated and fixed on the outer surface 21 a and the end surface 21 c of the eggshell 21 and enters the pores of the eggshell 21. That is, the pores of the eggshell 21 are covered and closed by the coating layer 16. Thereby, the eggshell 21 covered with the coating layer 16 is in a state where the pores are closed, so that excellent strength is obtained.
 コーティング層16で補強されて強化された卵殻21からなる容器10の本体部11は、食品用の容器等としての使用に耐え得る十分な強度を有する。具体的に、本体部11は、内部に充填された内容物を食する時に加えられる外力や輸送時等に加えられる外力に対する耐久性を有している。これにより、本体部11が破損することによる内容物の漏れや品質の劣化等を防止できる。また、卵殻21の強度が高められることにより、食品用の容器等として容器10を繰り返し使用できる。また、容器10は、食品用の容器等として用いられた後、栽培用プランターや他の物品等を収納する容器等として使用されても良い。 (4) The main body 11 of the container 10 composed of the eggshell 21 reinforced and reinforced by the coating layer 16 has sufficient strength to withstand use as a food container or the like. Specifically, the main body 11 has durability against an external force applied when eating the contents filled therein or an external force applied during transportation or the like. Thereby, leakage of contents, deterioration of quality, and the like due to breakage of the main body 11 can be prevented. In addition, since the strength of the eggshell 21 is increased, the container 10 can be repeatedly used as a food container or the like. Further, the container 10 may be used as a container for accommodating a planter for cultivation or other articles after being used as a container for food or the like.
 また、本体部11は、食品等の製造過程における加熱調理による温度上昇や、内部に充填された食品等が膨張する圧力にも耐えることができる。そのため、本体部11の内部に食品等の素材を充填して加熱調理することも可能であり、容器10を用いて販売等される加工食品等の調理効率を高めることができる。 本体 Further, the main body 11 can withstand a temperature rise due to heating and cooking in the process of manufacturing food and the like and a pressure at which the food and the like filled therein expands. Therefore, it is possible to fill the inside of the main body 11 with a material such as food and cook it by heating, and it is possible to increase the cooking efficiency of processed food and the like sold using the container 10.
 台座部12は、コーティング層16と同様に形成されたコーティング層17にて覆われている。詳しくは、台座部12を構成する卵殻22の外表面22aおよび開口部15の端面22cには、コーティング層16と同等のコーティング層17が積層されて固着している。コーティング層17は、卵殻22の気孔に入り込んで塞いでいる。台座部12の卵殻22にコーティング層17が形成されることにより、卵殻22の強度が高められ、卵殻22が壊れ難くなる。これにより、台座部12は、本体部11を好適に支えることができる。なお、これらコーティング層16,17は、本体部11および台座部12の少なくとも一部が覆われていることにより、これら本体部11および台座部12のコーティング層16,17にて覆われた部分を補強できる。 The pedestal portion 12 is covered with a coating layer 17 formed in the same manner as the coating layer 16. Specifically, a coating layer 17 equivalent to the coating layer 16 is laminated and fixed to the outer surface 22a of the eggshell 22 and the end surface 22c of the opening 15 constituting the pedestal portion 12. The coating layer 17 has entered and closed the pores of the eggshell 22. By forming the coating layer 17 on the eggshell 22 of the pedestal portion 12, the strength of the eggshell 22 is increased, and the eggshell 22 is hardly broken. Thereby, the pedestal portion 12 can suitably support the main body portion 11. Since the coating layers 16 and 17 cover at least a part of the main body 11 and the pedestal 12, the portions of the main body 11 and the pedestal 12 that are covered by the coating layers 16 and 17 are covered. Can be reinforced.
 次に、コーティング層16についてさらに詳しく説明する。なお、上記のとおり、台座部12に形成されるコーティング層17は、コーティング層16と同等である。コーティング層16を形成するコーティング剤としては、種々の材料を利用可能である。 Next, the coating layer 16 will be described in more detail. As described above, the coating layer 17 formed on the pedestal portion 12 is equivalent to the coating layer 16. Various materials can be used as the coating agent for forming the coating layer 16.
 さらに、コーティング層16は、例えばセルロースナノファイバー等の1層であっても良いが、複数の層、例えば2層で構成してもよい。具体的に、コーティング層16としては、卵殻21の外表面21aや切断された端面21c上に直接積層される第1の層18と、この第1の層18上に積層される第2の層19とで構成している。第1の層18は、水溶性多糖類であるプルランを主成分とした層であり、水とプルランとを含有し、プルランの含有率が水に対し12.5重量%以上17.5重量%以下、より好ましくは15重量%とされている。 Furthermore, the coating layer 16 may be a single layer of, for example, cellulose nanofibers, or may be composed of a plurality of layers, for example, two layers. Specifically, as the coating layer 16, a first layer 18 directly laminated on the outer surface 21 a or the cut end surface 21 c of the eggshell 21 and a second layer laminated on the first layer 18 19. The first layer 18 is a layer mainly composed of pullulan, which is a water-soluble polysaccharide, and contains water and pullulan. The content of pullulan is 12.5% by weight or more and 17.5% by weight with respect to water. Hereinafter, it is more preferably 15% by weight.
 ここで、プルラン(pllulan)は、分子式C10であり、無色透明な化合物であって、グルコースのみからなる多糖類の一種である。そして、プルランは、グルコース3分子がα1-4結合したマルトトリオースがα1-6結合で繋がった構造を有している。また、プルランは、溶性に優れ、速やかに水に溶解する性質を有しており、増粘性、接着性、付着性、粘着性、造膜性、被膜性などに優れ、可食性である。よって、プルランは、一定の水を加えて加熱成型すると、可食水溶性の成型物、具体的な層状の膜を形成できる物質である。さらに、プルランは、急性毒性、亜急性毒性、慢性毒性、変異原性において安全性が確認されており、日本では使用制限のない添加物として扱われている。なお、第1の層18としてプルランを用いることにより、卵20の卵殻20,21,22に対する第1の層18の付着性や被膜性が向上する。なお、第1の層18は、プルランの他、例えばアラビアガム等の水溶性多糖類である植物性樹脂など、種々の成分を主成分として用いることもできる。 Here, pullulan has a molecular formula of C 6 H 10 O 5 , is a colorless and transparent compound, and is a kind of polysaccharide composed of only glucose. Pullulan has a structure in which maltotriose, in which three glucose molecules are α1-4 bonded, is connected by α1-6 bonds. In addition, pullulan has excellent solubility and has a property of rapidly dissolving in water, and is excellent in viscosity increasing, adhesiveness, adhesiveness, adhesiveness, film forming property, coating property and the like, and is edible. Therefore, pullulan is a substance that can form an edible water-soluble molded product, specifically, a layered film, when heated and molded by adding a certain amount of water. Furthermore, pullulan has been confirmed to be safe in acute toxicity, subacute toxicity, chronic toxicity, and mutagenicity, and is treated as an unrestricted additive in Japan. The use of pullulan as the first layer 18 improves the adhesion and coating properties of the first layer 18 to the eggshells 20, 21, 22 of the egg 20. Note that the first layer 18 can also use, as a main component, various components other than pullulan, such as a vegetable resin which is a water-soluble polysaccharide such as gum arabic.
 また、第2の層19は、熱可塑性樹脂であるシェラックを主成分とした層とされている。シェラック(shellac)は、ラックカイガラムシ(Laccifer lacca)等の数種のカイガラムシが分泌する虫体被覆物を精製して得られた樹脂状物質である。そして、シェラックは、透明な無味無臭の人体に無害な物質であって、一般的に食品のコーティング材として利用されている鮮度保持効果を有する光沢剤製剤である。また、シェラックは、例えばエタノール等のアルコール系溶剤のみに溶ける性質を有しており、シェラックのアルコール溶液を乾燥させてアルコールを蒸発させることにより透明な皮膜を形成できる防湿材である。 {Circle around (2)} The second layer 19 is a layer mainly composed of shellac which is a thermoplastic resin. Shellac is a resinous substance obtained by purifying insect coatings secreted by several types of scale insects, such as raccoon (Laccifer @ lacca). Shellac is a transparent, tasteless and odorless harmless substance that is harmless to the human body, and is a brightener preparation that has a freshness retaining effect and is generally used as a food coating material. Shellac has a property of being soluble only in an alcohol-based solvent such as ethanol, and is a moisture-proof material capable of forming a transparent film by drying an alcohol solution of shellac and evaporating alcohol.
 したがって、卵30の卵殻20,21,22にプルラン水溶液を塗布してから乾燥させて第1の層18とし、この第1の層18上にシェラック液を塗布してアルコール分を揮発させて硬化させることにより、一部を切り取ると強度が極端に低下する卵殻20,21,22であっても強固に補強できるとともに、卵殻21,22にて構成された容器10を食品の容器等として用いた場合に、誤って口を付けてしまった際の人的被害を防止できる。また同時に、表面に水が付着した場合における第1の層18の溶け出しを第2の層19にて防止できる。 Therefore, the aqueous pullulan solution is applied to the eggshells 20, 21, 22 of the egg 30 and then dried to form the first layer 18, and the shellac liquid is applied to the first layer 18 to volatilize the alcohol and harden. By doing so, even the eggshells 20, 21, 22 whose strength is extremely reduced when a part thereof is cut off can be strongly reinforced, and the container 10 composed of the eggshells 21, 22 is used as a food container or the like. In this case, it is possible to prevent human damage when the user accidentally puts his mouth. At the same time, the second layer 19 can prevent the first layer 18 from dissolving when water adheres to the surface.
 また、容器10は、植物栽培用のポット等として用いられても良い。したがって、コーティング層16を天然成分にて形成していることにより、容器10は、土壌に埋められることで土壌に還元される。そのため、容器10は、植物とともに土壌に埋め込まれても良く、育苗用の容器等としても有用である。このとき、栽培用の培土より先に卵殻23を容器10へ入れることにより、容器10内の培土へ空気が入りやすくなり、栽培する植物の根張りを良くできる。 The container 10 may be used as a pot for plant cultivation. Therefore, since the coating layer 16 is formed of a natural component, the container 10 is reduced to the soil by being buried in the soil. Therefore, the container 10 may be embedded in the soil together with the plant, and is useful as a container for raising seedlings. At this time, by putting the eggshell 23 into the container 10 prior to cultivation for cultivation, air can easily enter the cultivation in the container 10 and the rooting of the plant to be cultivated can be improved.
 土壌中に埋められた容器10は、土壌に還元されるため、従来の合成樹脂製のポットのように容器10を掘り起こして回収し、洗浄、保管、管理等する必要がない。また、酸性の土壌では、卵殻20からなる容器10が埋められることによって、土壌が中和されてPh値が高くなり、土壌を改良できる。また、容器10内に植えられた植物は、芽が伸びる上部以外が容器10によって包まれる。これにより、容器10は、養分流出の防止や保湿に優れた効果を発揮する。また、根の成長を阻害したくない場合には、容器10の下部のみを割って植え付ければ良い。 (4) Since the container 10 buried in the soil is reduced to the soil, there is no need to dig up and collect the container 10 like a conventional synthetic resin pot, and to perform cleaning, storage, management, and the like. Further, in the case of acidic soil, by burying the container 10 made of the eggshell 20, the soil is neutralized and the Ph value is increased, so that the soil can be improved. In addition, the plant planted in the container 10 is covered by the container 10 except for the upper part where the buds grow. Thereby, the container 10 exhibits an excellent effect of preventing nutrient outflow and moisture retention. If it is not desired to inhibit the growth of the root, only the lower part of the container 10 may be split and planted.
 また、容器10としては、iPS細胞やミューズ細胞などを培養するための培養空間用の容器として用いることもできる。 容器 The container 10 can also be used as a container for a culture space for culturing iPS cells, muse cells, and the like.
 さらに、容器10を食用として用いた場合には、匙(スプーン)が付属されていることが多い。この場合、この匙を、食後の容器10を植物栽培用の容器として利用する際の、培土用のスコップ、すなわち栽培用シャベルとして用いることができる。また、この匙に、種子の種類や栽培履歴等を表示できる部位を設けたり、文字や絵などが描きやすい素材で形成したりコーティングを施したりして、食後に匙を、栽培用の立て札として用いることができる。また、この匙に、土壌の保湿・乾燥度合いを示す機能性を付加することもできる。ゆえに、スマートフォンなどの情報端末と専用アプリとが連動する栽培センターにより、栽培状況や栽培環境を可視化して愉しむ園芸文化を創出することもできる。 Furthermore, when the container 10 is used for food, a spoon is often attached. In this case, this spoon can be used as a scoop for cultivation, that is, a shovel for cultivation when the container 10 after eating is used as a container for plant cultivation. In addition, this spoon is provided with a part that can display the type of seed, cultivation history, etc., and is formed or coated with a material that is easy to draw letters and pictures, etc. Can be used. In addition, functionality indicating the degree of moisture retention and drying of the soil can be added to this spoon. Therefore, the cultivation center in which the information terminal such as a smartphone and the dedicated application are linked can create a horticultural culture in which the cultivation situation and the cultivation environment can be visualized and enjoyed.
 また、容器10をプリン用とし、この容器10に、カラメルソースを入れたじょうろ型容器を付属させることにより、このじょうろ型容器を栽培用のじょうろとして使用できる。そして、このじょうろ用容器の注ぎ口の先をつまみ切ったり、ねじって蓋を外す等することにより、じょうろ型容器内のカラメルソースが開封され、このじょうろ型容器を押しつぶしてスポイトのように用いることにより、じょうろ型容器からカラメルソースを取りだすことができる。 Also, by using the container 10 for pudding and attaching a watering can type container containing a caramel sauce to the container 10, the watering can type container can be used as a watering can for cultivation. Then, the caramel sauce in the watering can is opened by pinching the tip of the spout of the watering can or twisting off the lid, and crushing the watering can to use it like a dropper. Thereby, a caramel sauce can be taken out from a watering can type container.
 次いで、図4(A)は、容器10の素材となる卵30の平面図である。図4(B)は、卵30の正面図である。なお、卵30のやや太く形成される気室側を上とし、その反対側のやや尖っている端部側を下として説明する。また、図4(A)および図4(B)に示す一点鎖線は、容器10を形成する際に、卵30が切断される箇所を示している。ここで、卵30は、炭酸カルシウムが主成分であり、多くの気孔を有することから、外力を作用させると略塑性変形せず砕ける性質を有する脆性材である。 Next, FIG. 4A is a plan view of an egg 30 serving as a material of the container 10. FIG. 4B is a front view of the egg 30. The description will be made assuming that the air chamber side of the egg 30 which is formed slightly thick is the upper side, and the slightly sharp end side opposite to the lower side is the lower side. 4 (A) and 4 (B) indicate the locations where the eggs 30 are cut when the container 10 is formed. Here, the egg 30 is a brittle material that has a property of being crushed without being substantially plastically deformed when an external force is applied since the egg 30 is mainly composed of calcium carbonate and has many pores.
 図4(A)および図4(B)に示すように、卵30は切断部31にて切断され、これにより本体部11となる卵殻21が形成される。切断部31は、卵30の中心軸に対して略垂直であり、平面視において略円形状である。なお、切断部31は、容器10の意匠性を高めるために、例えば、略波状等に形成されても良い。卵30の上端から切断部31までの距離L2は、卵30の高さL1の3分の1以下が望ましい。すなわち、本体部11となる卵殻21の高さL3は、卵30の高さL1の3分の2以上である。これにより、卵殻21は容器10として好適な大きさになる。 卵 As shown in FIGS. 4 (A) and 4 (B), the egg 30 is cut at the cutting portion 31, thereby forming the eggshell 21 which becomes the main body 11. The cutting portion 31 is substantially perpendicular to the central axis of the egg 30 and has a substantially circular shape in plan view. The cut portion 31 may be formed in, for example, a substantially wavy shape in order to enhance the design of the container 10. The distance L2 from the upper end of the egg 30 to the cutting portion 31 is desirably not more than one third of the height L1 of the egg 30. That is, the height L3 of the eggshell 21 serving as the main body 11 is two thirds or more of the height L1 of the egg 30. Thereby, the eggshell 21 becomes a suitable size for the container 10.
 また、切断部31で切除された卵30が台座本体13となり、この台座本体13の上部がさらに切断部32で切断されることにより、台座部12となる卵殻22が形成される。すなわち、台座本体13は、卵殻22と、切断部32にて切断された卵殻23とで構成された蓋体としての小片部である。切断部32は、卵30において切断部31よりも上方であり、切断部31の外形寸法より小さな外径寸法を有しており、切断部31と切断部32とは略平行となっている。よって、卵30の卵殻20から容器10の本体部11および台座部12が形成されることにより、従来は廃棄されていた卵殻20を容器10として有効に再利用できる。これにより、卵30の卵殻20の廃棄量を減少できる。また、食品用等の容器としてガラス製やプラスチック製等の容器や台座を別途購入する必要がなくなるので、ガラスやプラスチック等の消費量および廃棄量を削減できる。ゆえに、フランス料理、日本料理をはじめ、特に欧米の料理文化に絶大なる演出効果のみならず、サスティナブル意識を提供できる。 The egg 30 cut off by the cutting portion 31 becomes the pedestal main body 13, and the upper portion of the pedestal main body 13 is further cut by the cutting portion 32 to form the eggshell 22 that becomes the pedestal portion 12. That is, the pedestal main body 13 is a small piece portion as a lid constituted by the eggshell 22 and the eggshell 23 cut by the cutting portion 32. The cutting portion 32 is located above the cutting portion 31 in the egg 30 and has an outer diameter smaller than the outer dimension of the cutting portion 31, and the cutting portion 31 and the cutting portion 32 are substantially parallel. Therefore, by forming the main body portion 11 and the pedestal portion 12 of the container 10 from the eggshell 20 of the egg 30, the eggshell 20 that has been conventionally discarded can be effectively reused as the container 10. Thereby, the amount of discarded eggshell 20 of egg 30 can be reduced. Further, since it is not necessary to separately purchase a container or a base made of glass or plastic as a container for food or the like, consumption and disposal of glass and plastic can be reduced. As a result, it is possible to provide not only a great production effect for French and Japanese cuisines, but also European and American cuisine cultures, as well as sustainability.
 また、一つの容器10を構成する本体部11と台座部12とは、それぞれ別々の卵30から得られた卵殻21,22から形成することもできる。すなわち、一の卵殻20を切除して得られた卵殻21は、他の卵殻20を切除して得られた卵殻22と組み合わせて容器10が構成される。これにより、容器10の生産効率が高められるとともに、卵殻21,22の選択が可能となり、容器10の意匠性が高められる。ただし、卵殻20を切断部32にて開口したものであっても、容器10に比べて保湿性に優れ強度が増した容器として用いることができる。 The body 11 and the pedestal 12 constituting one container 10 can also be formed from eggshells 21 and 22 obtained from separate eggs 30 respectively. That is, the container 10 is configured by combining the eggshell 21 obtained by cutting one eggshell 20 with the eggshell 22 obtained by cutting the other eggshell 20. Thereby, the production efficiency of the container 10 is improved, and the eggshells 21 and 22 can be selected, and the design of the container 10 is enhanced. However, even if the eggshell 20 is opened at the cut portion 32, the eggshell 20 can be used as a container having excellent moisture retention and increased strength as compared with the container 10.
 なお、卵30は、自然物であるため、個体毎に大きさが異なる。そのため、卵30の高さL1に応じて、切断部31の位置を適宜変更することにより、本体部11の高さL3を調整しても良い。また、上記の例では卵30の上部が切除されて本体部11が形成されるとしたが、本体部11の構成はこれに限定されず、例えば、卵30の下部が切除されて、卵30の気室側の卵殻20が本体部11として使用されても良い。また、例えば、本体部11は、卵30を上下方向、即ち中心軸方向に切断することにより形成されても良い。 卵 Because the egg 30 is a natural product, the size of the egg 30 differs for each individual. Therefore, the height L3 of the main body 11 may be adjusted by appropriately changing the position of the cutting portion 31 according to the height L1 of the egg 30. In the above example, the upper part of the egg 30 is cut off to form the main body 11, but the configuration of the main body 11 is not limited to this. For example, the lower part of the egg 30 is cut off, The eggshell 20 on the air chamber side may be used as the main body 11. Further, for example, the main body 11 may be formed by cutting the egg 30 in the vertical direction, that is, in the central axis direction.
 さらに、卵殻21,22の外表面21a,22aに形成されるコーティング層16,17は、上記の例に限定されず、これら卵殻21,22の外表面21a,22aの少なくとも一部に形成されていてもよい。具体的には、コーティング層16,17は、強度が弱い箇所、例えば卵殻21の切断部31の端面21cや、卵殻22の切断部31,32それぞれの端面21c,22cを覆うように形成されても良い。 Furthermore, the coating layers 16 and 17 formed on the outer surfaces 21a and 22a of the eggshells 21 and 22 are not limited to the above examples, and are formed on at least a part of the outer surfaces 21a and 22a of the eggshells 21 and 22. You may. More specifically, the coating layers 16 and 17 are formed so as to cover portions having low strength, for example, end surfaces 21c of the cut portions 31 of the eggshell 21 and end surfaces 21c and 22c of the cut portions 31 and 32 of the eggshell 22, respectively. Is also good.
 また、卵殻21,22は、それぞれの内表面21b,22bに卵殻膜が残された状態で容器10に用いても良い。これにより、卵殻21,22は、卵殻膜にて保護され、容器10の強度が高められ補強される。また、内表面21bの卵殻膜の内側にコーティング層16が形成されても良い。これにより、卵殻21は、卵殻膜およびコーティング層16にて保護され強度が高められ補強される。卵殻22についても、卵殻21と同様に、卵殻膜の上にコーティング層17が形成されても良い。また、これらコーティング層16,17の厚さを調整することによって、これらコーティング層16,17にて外表面21a,22aが覆われた卵殻21,22の大きさを等しくし、これら卵殻21,22の個体差を吸収してもよい。 The eggshells 21 and 22 may be used for the container 10 with the eggshell membranes left on the inner surfaces 21b and 22b. Thereby, the eggshells 21 and 22 are protected by the eggshell membrane, and the strength of the container 10 is enhanced and reinforced. Further, the coating layer 16 may be formed inside the eggshell membrane on the inner surface 21b. Thereby, the eggshell 21 is protected by the eggshell membrane and the coating layer 16, and its strength is enhanced and reinforced. As for the eggshell 22, the coating layer 17 may be formed on the eggshell membrane similarly to the eggshell 21. Further, by adjusting the thickness of the coating layers 16 and 17, the sizes of the eggshells 21 and 22 having the outer surfaces 21a and 22a covered by the coating layers 16 and 17 are made equal, and the eggshells 21 and 22 are made equal. May be absorbed.
 また、卵殻21,22は、卵殻膜が除去された状態で容器10に用いられても良い。具体的には、エタノールや水等によって、卵殻21,22の卵殻膜が洗浄等されて剥離しても良い。これにより、卵殻膜の腐敗等の恐れがなくなるため、容器10の保存性が高められる。また、卵殻膜が剥離された内表面21b,22bにコーティング層16,17を形成しても良い。すなわち、これらコーティング層16,17等のコーティング剤で覆われていない卵殻21,22であってもよい。 The eggshells 21 and 22 may be used for the container 10 with the eggshell membranes removed. Specifically, the eggshell membranes of the eggshells 21 and 22 may be washed and removed with ethanol, water, or the like. As a result, there is no possibility that the eggshell membranes will rot, and the storage stability of the container 10 is improved. Further, the coating layers 16 and 17 may be formed on the inner surfaces 21b and 22b from which the eggshell membrane has been peeled off. That is, the eggshells 21 and 22 that are not covered with the coating agent such as the coating layers 16 and 17 may be used.
 以上により、本発明に係る容器10は、一つの生の卵30を例として考えると、目前や冷蔵庫に卵30が一つ存在するのではなく、一個分の卵黄、および一個分の卵白のみならず、それに加え一個の本体部11の素材と、その本体部11を自立させる台座部12の素材とを創出する素材があるという世界観が創造される。また、本発明を、生の卵30を中心とした卵殻形状物で実施するということは、食文化・滋養といった側面に加え、サスティナブル社会に向けたエコロジカル性、さらには、イースターエッグをはじめとした生命・誕生・復活・再生・財産等の象徴でもある卵30を、エシカルな消費文化およびイノベーションの象徴・多様な場面でのアイコンとして営為に世界観を据え直すことこそが、その産業性をもった真のコロンブスの卵の真骨頂であり、例え、千年の時が経とうとも廃れることなき自然の意匠美によりもたらされた、ユニバーサルデザインによる包摂的文化創造なものである。 As described above, the container 10 according to the present invention, when considering one raw egg 30 as an example, instead of having one egg 30 at hand or in the refrigerator, if only one egg yolk and one egg white are present, In addition, a world view is created in which there is a material that creates the material of one main body 11 and the material of the pedestal 12 that makes the main body 11 independent. In addition, the fact that the present invention is embodied in an eggshell-shaped product centered on raw eggs 30 means that, in addition to aspects such as food culture and nutrition, ecological properties for a sustainable society, and furthermore, such as Easter eggs Egg 30, which is a symbol of life, birth, resurrection, regeneration, property, etc., is a symbol of ethical consumption culture and innovation, and an icon in various scenes. It is the true value of a true Columbus egg, and it is an inclusive culture created by universal design, brought about by the beauty of natural design that never goes away, even after a millennium.
[容器の製造方法]
 次に、図5を参照して、卵殻形状容器である容器10の製造方法について詳細に説明する。なお、以下の説明では、適宜図1ないし図4を参照するものとする。
[Container manufacturing method]
Next, a method of manufacturing the container 10 which is an eggshell-shaped container will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 図5は、本発明の実施形態に係る容器10の製造工程を示すフローチャートである。図5に示すように、容器10の製造工程は、消毒工程S10と、第1コーティング工程S20と、第1割卵工程S30と、第1洗浄工程S40と、縁部コーティング工程S50と、第2割卵工程S60と、第2洗浄工程S70と、第2コーティング工程S80と、印刷工程S90と、を備える。 FIG. 5 is a flowchart showing a manufacturing process of the container 10 according to the embodiment of the present invention. As shown in FIG. 5, the manufacturing process of the container 10 includes a disinfection process S10, a first coating process S20, a first egg breaking process S30, a first cleaning process S40, an edge coating process S50, a second It includes a breaking step S60, a second cleaning step S70, a second coating step S80, and a printing step S90.
 まず、必要に応じ、消毒工程S10が行われる。消毒工程S10では、食品用エタノール等にて卵30の表面が消毒される。その後、卵30は、所定時間放置されて、表面を自然乾燥させる。 First, a disinfection step S10 is performed as necessary. In the disinfection step S10, the surface of the egg 30 is disinfected with food grade ethanol or the like. Thereafter, the egg 30 is left for a predetermined time to allow the surface to dry naturally.
 次に、必要に応じ、第1コーティング工程S20が行われる。第1コーティング工程S20では、卵30の卵殻20の表面全体にコーティング層16,17が形成されて補強される。このとき、これらコーティング層16,17に、色付きのコーティング剤を用いることにより、天然物であるが所以の卵殻20の色むら、すなわち下地むらを抑制できる。また、この第1コーティング工程S20を行うことによって、後述する第1割卵工程S30での割卵を安定して行うことが可能となる。 Next, a first coating step S20 is performed as necessary. In the first coating step S20, the coating layers 16 and 17 are formed on the entire surface of the eggshell 20 of the egg 30 and reinforced. At this time, by using a colored coating agent for the coating layers 16 and 17, it is possible to suppress the color unevenness of the eggshell 20, which is a natural product, that is, the base unevenness. Further, by performing the first coating step S20, it becomes possible to stably perform the breaking in the first breaking step S30 described later.
 例えば、これらコーティング層16,17が、プルランを主成分とする第1の層18の表面に、シェラックを主成分とする第2の層19を積層させて形成される場合、水とプルランとの混合物であるプルラン水溶液に卵30を浸漬させて、プルラン水溶液が卵30の表面に塗布される。次いで、プルラン水溶液が塗布された卵30を、オーブン等の加熱装置で加熱したり、ドライヤー等で熱風を吹き付けたり、自然乾燥させたりして乾燥させて、プルラン水溶液を硬化させて卵30の表面に第1の層18を形成する。 For example, when these coating layers 16 and 17 are formed by laminating a second layer 19 mainly composed of shellac on the surface of a first layer 18 mainly composed of pullulan, water and pullulan are mixed. The egg 30 is immersed in the aqueous pullulan solution as a mixture, and the aqueous pullulan solution is applied to the surface of the egg 30. Next, the egg 30 to which the aqueous pullulan solution has been applied is heated by a heating device such as an oven, blown with hot air by a drier or the like, or naturally dried to be dried, and the aqueous solution of pullulan is cured to cure the surface of the egg 30. Then, a first layer 18 is formed.
 その後、第1の層18が表面に積層されて形成された卵30を、シェラック液(シェラックとエタノール等のアルコールを混合した溶液)に浸漬させて、卵30の第1の層18上にシェラック液を塗布させる。次いで、シェラック液が塗布された卵30を、オーブン等の加熱装置で加熱したり、ドライヤー等で熱風を吹き付けたり、自然乾燥させたりして、シェラック液中のアルコール成分を蒸発させて、シェラックを硬化させて卵30の第1の層18上に第2の層19を積層させて形成する。 Thereafter, the egg 30 formed by laminating the first layer 18 on the surface is immersed in a shellac solution (a solution in which shellac and an alcohol such as ethanol are mixed) to form shellac on the first layer 18 of the egg 30. Apply the liquid. Next, the egg 30 to which the shellac liquid has been applied is heated with a heating device such as an oven, blows hot air with a drier or the like, or is naturally dried to evaporate the alcohol component in the shellac liquid, thereby forming shellac. After curing, the second layer 19 is formed on the first layer 18 of the egg 30 by lamination.
 このとき、図示しない超音波機構やマイクロバブル発生装置を用いて、プルラン水溶液やシェラック液等のコーティング剤を卵30の卵殻20に塗布するようにして、この卵殻20を殺菌すると同時に、この卵殻20の気孔やバリをコーティング剤で埋めて、卵殻20をより強固にしてもよい。 At this time, a coating agent such as a pullulan aqueous solution or a shellac solution is applied to the eggshell 20 of the egg 30 using an ultrasonic mechanism or a microbubble generator (not shown), so that the eggshell 20 is sterilized. The pores and burrs may be filled with a coating agent to make the eggshell 20 stronger.
 なお、コーティング層16,17として用いるコーディング剤を自然乾燥させる際には、後述する乾燥用治具900が用いられる。各卵殻21は、開口部14を下方に向けた状態として、これら各卵殻21の開口部14に乾燥用治具900の支柱902を挿入していき、これら各卵殻21の開口部14に対向する内表面21bが、支柱902の先端部に取り付けられた緩衝部材903上に載置するように設置される。また、台座本体13は、切断部31側を下方に向けた状態として、これら台座本体13の端部側の内表面が乾燥用治具900の緩衝部材903上に載置するように設置される。 When the coating agent used as the coating layers 16 and 17 is naturally dried, a drying jig 900 described later is used. Each egg shell 21 inserts the support 902 of the drying jig 900 into the opening 14 of each egg shell 21 with the opening 14 facing downward, and faces the opening 14 of each egg shell 21. The inner surface 21 b is set so as to be placed on the buffer member 903 attached to the tip of the column 902. Further, the pedestal main body 13 is set such that the inner surfaces of the end portions of the pedestal main body 13 are placed on the buffer member 903 of the drying jig 900 with the cutting section 31 side facing downward. .
 次に、第1割卵工程S30が行われる。第1割卵工程S30では、卵30は、切断部31にて後述する割卵機100A等にて切断される。割卵機100A等は、例えば略円板状の切削刃本体102Aを有しており、この切削刃本体102Aを超音波振動させたり回転させたりして、この切削刃本体102Aの刃112Aを卵30の卵殻20の所定位置に接触させることによって、この卵30の卵殻20の一部が切断部31にて部分的に切り取られて本体部11となる卵殻21と台座本体13とに切断される。そして、卵30は、中身と卵殻21,22,23とに分離される。卵30の中身は、例えば、洋菓子等の材料として使用される。 Next, the first egg breaking step S30 is performed. In the first egg breaking step S30, the egg 30 is cut at the cutting section 31 by an egg breaking machine 100A or the like described later. The egg breaking machine 100A or the like has, for example, a substantially disk-shaped cutting blade main body 102A, and ultrasonically vibrates or rotates the cutting blade main body 102A so that the blade 112A of the cutting blade main body 102A is egg-shaped. By making contact with a predetermined position of the eggshell 20 of the egg 30, a part of the eggshell 20 of the egg 30 is partially cut off at the cutting portion 31 and cut into the eggshell 21 and the pedestal main body 13 serving as the main body 11. . Then, the egg 30 is separated into the contents and the eggshells 21, 22, 23. The contents of the egg 30 are used, for example, as a material for Western confectionery or the like.
 ここで、第1コーティング工程S20にて卵30の表面にコーティング層16,17を形成した後に第1割卵工程S30を行うことにより、卵30の卵殻20はコーティング層16,17にて保護されて補強されるため、割卵工程S30での割卵時の卵殻20のひび割れ等が防止される。また、割卵機100A等にて卵30の卵殻20が切断されることにより、卵30の卵殻20を手作業で割る場合に比べ、卵30の卵殻20のひび割れが少なくなるとともに強度が高くなる。また、割卵機100A等を用いることにより、容器10の生産性を高めることができる。 Here, the eggshell 20 of the egg 30 is protected by the coating layers 16 and 17 by performing the first split egg step S30 after forming the coating layers 16 and 17 on the surface of the egg 30 in the first coating step S20. Since the eggshell 20 is reinforced, cracking of the eggshell 20 at the time of the egg breaking in the egg breaking step S30 is prevented. In addition, when the eggshell 20 of the egg 30 is cut by the egg breaking machine 100A or the like, the number of cracks in the eggshell 20 of the egg 30 is reduced and the strength is increased as compared with the case where the eggshell 20 of the egg 30 is manually broken. . In addition, the productivity of the container 10 can be increased by using the egg breaking machine 100A or the like.
 次に、必要に応じ、第1洗浄工程S40が行われる。第1洗浄工程S40では、本体部11となる卵殻21および台座本体13の外表面および内表面を水で洗浄する等してすすぎ洗いし、これら卵殻21および台座本体13に付着している切削片や卵黄、卵白、卵殻膜等を徐々する。 Next, a first cleaning step S40 is performed as necessary.

In the edge coating step S50, the coating layers 16 and 17 are formed on the edges of the eggshell 21 and the pedestal body 13, respectively, in the same manner as in the first coating step S20. In the edge coating step S50, in addition to applying each of the eggshell 21 and the pedestal body 13 by immersing them in an aqueous pullulan solution or a shellac solution, the end face 21c of the eggshell 21 or the cutting portion 31 of the pedestal body 13 is used. The side may be partially immersed in an aqueous pullulan solution, shellac solution, or the like, and the end surface 21c of the eggshell 21 and the end of the cut portion 31 of the pedestal body 13 may be partially coated.
 次に、第2割卵工程S60が行われる。第2割卵工程S60では、台座本体13を切断部32にて後述する割卵機100B等にて切断する。具体的には、割卵機100Bの円板状の切削刃本体102Bを超音波振動させたり回転させたりして、この切削刃本体102Bの刃112Bを台座本体13の端部側の中心位置に接触させることによって、この台座本体13の端部が切断部32にて部分的に切り取られて切断されて、卵殻22,23に分離される。 Next, a second egg breaking step S60 is performed. In the second egg breaking step S60, the pedestal main body 13 is cut at the cutting portion 32 by an egg breaking machine 100B or the like described later. Specifically, the disk-shaped cutting blade body 102B of the egg breaking machine 100B is ultrasonically oscillated or rotated so that the blade 112B of the cutting blade body 102B is positioned at the center position on the end side of the pedestal body 13. By making contact, the end of the pedestal main body 13 is partially cut off at the cutting portion 32 and cut, and separated into eggshells 22 and 23.
 次に、必要に応じ、第2洗浄工程S70が行われる。第2洗浄工程S70では、卵殻22の外表面22aおよび内表面22bを水で洗浄する等してすすぎ洗いし、この卵殻22に付着している切削片等を徐々する。 Next, a second cleaning step S70 is performed as necessary. In the second washing step S70, the outer surface 22a and the inner surface 22b of the eggshell 22 are rinsed by washing with water or the like, and the cuttings and the like attached to the eggshell 22 are gradually removed.
 この後、必要に応じ、第2コーティング工程S80が行われる。第2コーティング工程S80では、第1コーティング工程S20にて説明した方法と同様の方法によって、卵殻21,22それぞれの外表面21a,22aにコーティング層16,17形成されて、これら卵殻21,22から本体部11および台座部12が形成される。なお、第2コーティング工程S80では、卵殻21,22それぞれの内表面21b,22bにコーティング層16,17が形成されても良い。この場合において、これら卵殻21,22を、プルラン水溶液やシェラック液に浸漬させ、その全面にコーティング層16,17を形成する。 (4) Thereafter, the second coating step S80 is performed as necessary. In the second coating step S80, the coating layers 16 and 17 are formed on the outer surfaces 21a and 22a of the eggshells 21 and 22, respectively, by a method similar to the method described in the first coating step S20. The main body 11 and the base 12 are formed. In the second coating step S80, the coating layers 16 and 17 may be formed on the inner surfaces 21b and 22b of the eggshells 21 and 22, respectively. In this case, the eggshells 21 and 22 are immersed in an aqueous pullulan solution or shellac solution to form coating layers 16 and 17 on the entire surface.
 上記のように、第1コーティング工程S20および第2コーティング工程S80が行われることにより、コーティング層16,17は、それぞれ複数の層状となって厚く形成される。そのため、卵殻21,22の強度を高めることができる。 コ ー テ ィ ン グ As described above, by performing the first coating step S20 and the second coating step S80, the coating layers 16 and 17 are each formed in a plurality of layers and are formed thick. Therefore, the strength of the eggshells 21 and 22 can be increased.
 その後、容器10の外表面、例えば卵殻21の外表面21aに不可逆性の示温剤を塗布する印刷工程S90が行われてもよい。印刷工程S90では、容器10の外表面に、その容器10が何℃で何時間、例えば蒸された、すなわち加熱処理されたかを確認できる示温剤が印刷されていてもよい。これにより、例えば食品用の容器10として用いる場合においては、所定温度以上で所定時間の加熱で反応する不可逆性の示温剤とすることにより、サルモネラ菌をはじめとする種々の微生物の殺菌対策等として用いることができるから、食中毒等の発生を適切に防止でき、すなわち調理管理を容易に行うことができ、安全性を高めることができる。また同時に、例えば食品用の容器10として用いた場合における保温管理を容易にできる。 Then, a printing step S90 of applying an irreversible temperature indicator to the outer surface of the container 10, for example, the outer surface 21a of the eggshell 21, may be performed. In the printing step S90, a temperature indicator may be printed on the outer surface of the container 10 at which temperature at which the container 10 has been steamed, that is, whether the container 10 has been heat-treated. Thus, for example, when used as a food container 10, by using an irreversible temperature indicator that reacts by heating at a predetermined temperature or higher for a predetermined time, it is used as a sterilization measure for various microorganisms including Salmonella. Therefore, the occurrence of food poisoning or the like can be appropriately prevented, that is, cooking management can be easily performed, and safety can be improved. At the same time, for example, it is possible to easily manage the heat retention when used as a food container 10.
 なお、この印刷工程S90の代わりに、予め示温剤が塗布されたシール材を、容器10の外表面21aの所定位置に張り付けるようにしてもよい。また、示温剤は、容器10のいずれかの位置に塗布等されていればよく、例えばコーティング層16,17に用いられるコーディング剤に示温剤を混ぜて用いてもよい。また、卵30の内容物、すなわち卵黄や卵白が、生、半熟、完熟の状態のいずれであるかを判別することができる示温剤としてもよい。さらに、示温剤の反応により、トレーサビリティーを可能にするシリアルナンバーや、シリアルバーコード、QRコード(登録商標)、バーコード、識別子などの表示を浮き出させることもできる。また、これらトレーサビリティーを可能にするシリアルナンバーや、シリアルバーコード、QRコード(登録商標)、バーコード、識別子などの種々の表示については、容器10のいずれかの位置に、例えばインクジェットプリンタ等を用いて印刷してもよい。 Instead of the printing step S90, a sealing material to which a temperature indicator is applied in advance may be attached to a predetermined position on the outer surface 21a of the container 10. The temperature indicator may be applied to any position of the container 10 or the like. For example, the temperature indicator may be mixed with a coding agent used for the coating layers 16 and 17. In addition, the temperature indicator may be used to determine whether the content of the egg 30, that is, the yolk or egg white is in a raw, semi-ripened, or ripe state. Furthermore, the display of a serial number, a serial barcode, a QR code (registered trademark), a barcode, an identifier, or the like that enables traceability can be raised by the reaction of the temperature indicator. For various displays such as a serial number, a serial barcode, a QR code (registered trademark), a barcode, and an identifier that enable the traceability, for example, an inkjet printer or the like may be provided at any position of the container 10. May be used for printing.
 このとき、容器10のそれぞれに、固有の識別コードを付けることもできる。この場合は、栽培する作物の栽培管理や、品評会、スマホアプリとの連動、IoT、AIを活用した養鶏、鶏卵の品質管理、鮮度管理が可能になるとともに、「CalaGARDEN」、「EGGGARDEN」、「たまご庭」などといった名称の食後の容器10の再活用を案内するサブカルチャーのHP等にアクセスさせたり、水やりや施肥のタイミングや分量を調整などする栽培用ゲーム等にアクセスさせたりできる。 At this time, a unique identification code can be attached to each of the containers 10. In this case, cultivation management of crops to be cultivated, product fairs, linkage with a smartphone application, chicken and egg management utilizing IoT and AI, quality control and freshness control can be performed, and “CalaGARDEN”, “EGGGARDEN”, “ It is possible to access a subculture HP or the like that guides the reuse of the container 10 after eating, such as an egg garden, or to access a cultivation game or the like that adjusts the timing or amount of watering or fertilization.
 また、第1コーティング工程S20、縁部コーティング工程S50、および第2コーティング工程S80は、それぞれ複数回行われても良い。これにより、コーティング層16,17を多層状に厚く形成でき、卵殻21,22の強度を高くできる。また、第1コーティング工程S20、縁部コーティング工程S50、および第2コーティング工程S80は、コーティング剤の種類を変えてそれぞれ複数回行われても良い。すなわち、コーティング層16,17は、それぞれ異なる種類のコーティング剤にて多層状に形成されても良い。 The first coating step S20, the edge coating step S50, and the second coating step S80 may each be performed a plurality of times. Thereby, the coating layers 16 and 17 can be formed thickly in a multilayer shape, and the strength of the eggshells 21 and 22 can be increased. Further, the first coating step S20, the edge coating step S50, and the second coating step S80 may be performed a plurality of times by changing the type of the coating agent. That is, the coating layers 16 and 17 may be formed in a multilayer shape using different types of coating agents.
 さらに、第1割卵工程S30および第2割卵工程S60は、第1割卵工程S30より先に第2割卵工程S60を行い、卵殻20から卵殻23を切り取った後、第1割卵工程S30を行って、卵殻23が切り取られた卵殻20から卵殻22を切り取って卵殻21を形成して、本体部11および台座部12を設けても良い。 Further, in the first egg breaking step S30 and the second egg breaking step S60, the second egg breaking step S60 is performed prior to the first egg breaking step S30, the eggshell 23 is cut off from the eggshell 20, and then the first egg breaking step S60 is performed. S30 may be performed to cut the eggshell 22 from the eggshell 20 from which the eggshell 23 has been cut to form the eggshell 21, and the main body portion 11 and the pedestal portion 12 may be provided.
[製品の製造方法]

[Product manufacturing method]
Next, a method for manufacturing a product using the container 10 will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 図6は、卵殻形状容器である容器10を用いた製品の製造方法を示すフローチャートである。図6に示すように、容器10を用いた製品の製造工程は、充填工程S100と、加熱調理工程S101と、第3コーティング工程S102と、梱包工程S103と、を備える。 FIG. 6 is a flowchart showing a method for manufacturing a product using the container 10 which is an eggshell-shaped container. As shown in FIG. 6, the product manufacturing process using the container 10 includes a filling process S100, a heating cooking process S101, a third coating process S102, and a packing process S103.
 初めに、充填工程S100が行われ、容器10の内部に内容物が充填される。内容物としては、例えば、調理不要な食品、調理済の食品または購入者によって加熱調理される食材等である。また、例えば、容器10がプリン等の洋菓子用の容器として用いられる場合は、容器10の内部に調合された液体状の材料が内容物として充填される。 First, the filling step S100 is performed, and the contents are filled in the container 10. The contents are, for example, foods that do not need to be cooked, cooked foods, or foods that are cooked by the purchaser. In addition, for example, when the container 10 is used as a container for western confectionery such as pudding, a liquid material prepared in the container 10 is filled as a content.
 次に、必要に応じ、加熱調理工程S101が行われる。加熱調理工程S101では、容器10に充填された内容物が加熱調理される。このとき、容器10および内容物が、示温剤が反応する加熱温度および加熱時間で加熱処理された場合には、示温剤が反応して、適切な加熱処理が行われたことを目視にて確認することが可能となる。そして、加熱調理が行われた後、容器10およびその内容物は冷却される。 Next, the heating and cooking step S101 is performed as necessary. In the heating and cooking step S101, the contents filled in the container 10 are heated and cooked. At this time, when the container 10 and the contents are heated at the heating temperature and the heating time at which the temperature indicator reacts, it is visually confirmed that the temperature indicator reacts and the appropriate heat treatment is performed. It is possible to do. After heating and cooking, the container 10 and its contents are cooled.
 その後、必要に応じ、第3コーティング工程S102が行われる。第3コーティング工程S102では、容器10の外表面にコーティング層16が形成される。これにより、容器10の強度をさらに高くできる。なお、加熱調理工程S101の加熱と第3コーティング工程S102の乾燥を同時に行うことも可能である。 Thereafter, a third coating step S102 is performed as necessary. In the third coating step S102, the coating layer 16 is formed on the outer surface of the container 10. Thereby, the strength of the container 10 can be further increased. Note that the heating in the heating and cooking step S101 and the drying in the third coating step S102 can be performed simultaneously.
 次に、梱包工程S103が行われ、容器10が所定の箱等に収納される。なお、容器10は、オブラート紙等にて包まれた状態で箱等に収納されても良い。これにより、容器10が外気から遮断されて内容物の品質劣化が抑制されるとともに、容器10が補強される。そして、内部に内容物が充填されて梱包された容器10は、その後、出荷される。 Next, the packing step S103 is performed, and the container 10 is stored in a predetermined box or the like. The container 10 may be housed in a box or the like in a state of being wrapped with oblate paper or the like. Thereby, the container 10 is shielded from the outside air, and the quality deterioration of the contents is suppressed, and the container 10 is reinforced. Then, the container 10 in which the contents are filled and packed is then shipped.
 また、卵30の卵殻20から形成した卵殻21,22,23のそれぞれの端部にコーティング剤等を塗布し、これら卵殻21,22,23を組み合わせて接着等させて、元の卵殻20形状とした状態で出荷させてもよい。この場合においては、卵殻23の外表面および内表面のそれぞれにコーティング層を設けておくことが好ましい。さらに、水やエタノールに浸した卵殻膜を容器10の開口部14の蓋として用いてもよい。 Further, a coating agent or the like is applied to each end of the eggshells 21, 22, 23 formed from the eggshell 20 of the egg 30, and the eggshells 21, 22, 23 are combined and adhered to form the original eggshell 20 shape. You may be made to ship in the state where it was done. In this case, it is preferable to provide a coating layer on each of the outer surface and the inner surface of the eggshell 23. Further, an eggshell membrane immersed in water or ethanol may be used as a lid of the opening 14 of the container 10.
[割卵機]
 次に、図7ないし図10を参照して、卵30の卵殻20を切断部31または切断部32にて切断するため割卵機100A,100Bについて詳細に説明する。なお、以下の説明では、適宜図1ないし図4を参照する。
[Egg breaking machine]
Next, with reference to FIGS. 7 to 10, the egg breaking machines 100A and 100B for cutting the eggshell 20 of the egg 30 at the cutting section 31 or the cutting section 32 will be described in detail. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
(超音波割卵機:別個型)
 図7ないし図10に示す本実施形態に係る割卵機100Aは、例えば卵30の卵殻20を切断部31にて切断するための切断機であり、この卵殻20の一部を切り取って開口部14を形成するための切削装置である。割卵機100Aは、作業者が把持する円柱状の把持本体101Aと、この把持本体101Aに取り付けられた円筒状の切削刃本体102Aと、切削刃本体102Aに超音波を付与して超音波振動させる超音波発生装置103Aと、超音波発生装置103Aへ電力を供給するための電源104Aとを備える。
(Ultrasonic egg breaking machine: separate type)
The egg breaking machine 100A according to the present embodiment shown in FIGS. 7 to 10 is, for example, a cutting machine for cutting the eggshell 20 of the egg 30 at the cutting section 31, and cuts a part of the eggshell 20 to open the egg shell 20. 14 is a cutting device for forming 14. The egg breaking machine 100A includes a cylindrical gripping body 101A gripped by an operator, a cylindrical cutting blade body 102A attached to the gripping body 101A, and ultrasonic vibration applied to the cutting blade body 102A. And a power supply 104A for supplying power to the ultrasonic generator 103A.
 図9に示すように、把持本体101Aは、円柱状に形成されており、この把持本体101Aの一端側に切削刃本体102Aが同心状に設けられている。これら把持本体101Aと切削刃本体102Aとは同一の外径寸法を有し一体に設けられている。切削刃本体102Aは、所定の厚さ寸法を有する円筒状の筒状部111Aとされ、この筒状部111の一端部に、複数、例えば125個の刃112Aが設けられている。これら刃112Aは、周方向に亘って連続して並べられて鋸状に形成されている。また、これら各刃112Aは、軸方向断面略三角形状に形成されており、図8に示すように、各刃112Aの外周側に傾斜面としての刃面113Aが形成されている。 As shown in FIG. 9, the grip main body 101A is formed in a cylindrical shape, and a cutting blade main body 102A is provided concentrically on one end side of the grip main body 101A. The grip body 101A and the cutting blade body 102A have the same outer diameter and are provided integrally. The cutting blade body 102A is a cylindrical tubular portion 111A having a predetermined thickness, and a plurality of, for example, 125 blades 112A are provided at one end of the tubular portion 111. These blades 112A are continuously arranged in the circumferential direction and formed in a saw shape. Each of the blades 112A has a substantially triangular cross section in the axial direction. As shown in FIG. 8, a blade surface 113A as an inclined surface is formed on the outer peripheral side of each of the blades 112A.
 ここで、刃面113Aが切削刃本体102Aの外周側に設けられているため、切削刃本体102Aの刃面113Aを卵30の卵殻20に食い込ませた際に生じる切削屑である切削片を、切削刃本体102Aの外周側に生じさせることができる。よって、卵30の卵殻20を開口する際における卵殻20の内部への切削片の侵入を防止できるため、開口部14を形成した後に卵殻20の内部から切削片を取り除く作業を簡略化でき、卵30の内容物、すなわち卵黄および卵白の利用を容易にできる。 Here, since the blade surface 113A is provided on the outer peripheral side of the cutting blade main body 102A, a cutting piece, which is a cutting waste generated when the blade surface 113A of the cutting blade main body 102A bites into the eggshell 20 of the egg 30, It can be generated on the outer peripheral side of the cutting blade body 102A. Therefore, since the cut pieces can be prevented from entering the inside of the eggshell 20 when the eggshell 20 of the egg 30 is opened, the operation of removing the cut pieces from the inside of the eggshell 20 after forming the opening 14 can be simplified, The use of 30 contents, namely egg yolk and egg white, can be facilitated.
 なお、切削刃本体102Aの刃112Aは、円筒状でなくてもよく、卵30の卵殻20に形成する開口部14の形状に対応させて、例えば断面が三角形型、ハート型、ひし型、貯金箱口型(卵殻の外表面に沿った弓なり型の長方形)、葉型、波線で囲った波型、折れ線で囲ったギザギザ型、三日月(ムーン)型、十字架型等の筒状とすることにより、開口部14の形状を様々な形状とすることができる。この場合、切削刃本体102Aの刃112Aの形状に対応させて、超音波発生装置103Aから付与する超音波の周波数を変化させる必要がある。 The blade 112A of the cutting blade body 102A may not be cylindrical, and may have, for example, a triangular cross section, a heart shape, a diamond shape, or a savings shape corresponding to the shape of the opening 14 formed in the eggshell 20 of the egg 30. Box-shaped (bow-shaped rectangle along the outer surface of the eggshell), leaf-shaped, wavy-shaped wavy, jagged-shaped, crescent-shaped (moon) -shaped, cross-shaped, etc. The shape of the opening 14 can be various shapes. In this case, it is necessary to change the frequency of the ultrasonic waves applied from the ultrasonic generator 103A according to the shape of the blade 112A of the cutting blade body 102A.
 さらに、切削刃本体102Aの刃112Aの周方向の一部を切り欠いた形状とし、卵殻20の切断時に卵殻21の一部が残るようにし、この卵殻21の残った部分をコーティング剤で強化したりシール溶剤で接合したりして、蓋として用いることもできる。 Further, a part of the blade 112A of the cutting blade body 102A in the circumferential direction is cut off so that a part of the eggshell 21 remains when the eggshell 20 is cut, and the remaining part of the eggshell 21 is reinforced with a coating agent. Alternatively, it can be used as a lid by bonding with a sealing solvent.
 各刃面113Aは、周方向に連続して形成されており、筒状部111Aの先端部に一体に設けられている。また、これら刃面113Aは、例えば35.5°の傾斜角度であって、これら各刃面113Aの根元部分の厚さ寸法が筒状部111Aの厚さ寸法より小さく形成されている。さらに、これら各刃面113Aの根元側である基端側には、周方向に連続した平面状のエッジ部114Aが形成されている。このエッジ部114Aは、刃面113Aの傾斜角度よりも小さな傾斜角度であって、エッジ部114Aの根元部分の厚さ寸法が刃面113Aの根元部分の厚さ寸法より大きく形成されている。 Each of the blade surfaces 113A is formed continuously in the circumferential direction, and is provided integrally with the tip of the tubular portion 111A. These blade surfaces 113A have an inclination angle of, for example, 35.5 °, and the thickness of the root portion of each blade surface 113A is formed smaller than the thickness of the cylindrical portion 111A. Further, a flat edge portion 114A that is continuous in the circumferential direction is formed on the base end side that is the root side of each of the blade surfaces 113A. The edge portion 114A has an inclination angle smaller than the inclination angle of the blade surface 113A, and the thickness of the root portion of the edge portion 114A is formed larger than the thickness size of the root portion of the blade surface 113A.
 エッジ部114Aの他端側、すなわち各刃面113Aの根元側には、周方向に連続した軸方向断面凹状である薄肉状の逃げ部115Aが設けられている。この逃げ部115Aは、各刃面113Aの根元部分からエッジ部114Aを介して離間した位置に周方向に亘って連続して設けられている。また、逃げ部115Aは、筒状部111Aの基端側に進むに連れて、エッジ部114Aの根元部分の厚さ寸法と同一の厚さ寸法から、このエッジ部114Aの根元部分の厚さ寸法より厚さ寸法を小さくし、さらに筒状部111Aの厚さ寸法と同一の厚さ寸法となるまでに亘って連続した滑らかな凹弧面状に形成されている。 他 端 The other end of the edge portion 114A, that is, the base side of each blade surface 113A, is provided with a thin-walled relief portion 115A having a concave shape in the axial direction that is continuous in the circumferential direction. The relief portion 115A is continuously provided in the circumferential direction at a position separated from the root portion of each blade surface 113A via the edge portion 114A. As the escape portion 115A advances toward the base end side of the cylindrical portion 111A, the thickness of the root portion of the edge portion 114A is reduced from the same thickness as the root portion of the edge portion 114A. The thickness is made smaller, and furthermore, it is formed into a continuous smooth concave arc shape until the thickness becomes the same as the thickness of the cylindrical portion 111A.
 すなわち、逃げ部115Aは、切削刃本体102Aの刃面113Aを卵殻20の表面に押し付けて食い込ませた際に、卵殻20への切削刃本体102Aの刃面113Aからの衝撃や応力を逃げ部115Aへ逃がすことができ、これら刃面113Aが卵殻20の食い込んだ部分に与える反力を分散させることができるから、卵殻20へ食い込んだ部分における径方向への亀裂の発生、すなわちひび割れの発生を抑制でき、卵殻20に開口部14を形成する作業を精度良く容易にできる。 That is, when the cutting surface 115A of the cutting blade body 102A is pressed against the surface of the eggshell 20 to make it bite, the relief portion 115A releases the impact and stress from the blade surface 113A of the cutting blade body 102A to the eggshell 20. And the blade surface 113A can disperse the reaction force exerted on the portion of the eggshell 20 that has been cut, so that the generation of radial cracks in the portion of the eggshell 20 that has been cut, that is, the occurrence of cracks, is suppressed. Thus, the operation of forming the opening 14 in the eggshell 20 can be accurately and easily performed.
 また、把持本体101Aの基端側には、超音波発生装置103Aが取り付けられている。超音波発生装置103Aは、切削刃本体102Aの刃面113Aを卵殻20の表面に押し付けて食い込ませ、卵殻20に円形状の切断部31を形成することに適した20kHz以上の所定の周波数の超音波を切削刃本体102Aの少なくとも刃112Aに付与する。なお、超音波発生装置103Aから付与する超音波の周波数は、切削刃本体102Aの刃112Aの厚さ寸法や外径寸法に起因して変化させる必要がある。さらに、超音波発生装置103Aは、把持本体101Aの外径寸法に等しい円柱状に形成されており、この把持本体101Aの基端側に同心状に取り付けられている。 超 Further, an ultrasonic generator 103A is attached to the base end side of the grip main body 101A. The ultrasonic generator 103A presses the blade surface 113A of the cutting blade main body 102A against the surface of the eggshell 20 so as to bite the same, and forms a circular cut portion 31 in the eggshell 20 at a predetermined frequency of 20 kHz or more suitable for forming the circular cut portion 31. A sound wave is applied to at least the blade 112A of the cutting blade main body 102A. Note that the frequency of the ultrasonic wave applied from the ultrasonic generator 103A needs to be changed due to the thickness and outer diameter of the blade 112A of the cutting blade body 102A. Further, the ultrasonic generator 103A is formed in a columnar shape equal to the outer diameter of the grip body 101A, and is attached concentrically to the base end side of the grip body 101A.
 さらに、超音波発生装置103Aの上側、すなわち基端側に電源104Aが取り付けられている。この電源104Aもまた、超音波発生装置103Aの外形寸法に等しい円柱状に形成されており、この超音波発生装置103Aの基端側に同心状に取り付けられている。また、この電源104Aの基端側には、電源104Aから超音波発生装置103Aへの電力の供給をオンオフさせるスイッチ105Aが設けられている。ここで、この電源104Aとしては、リチウムイオン電池等の充電池や、乾電池のほか、AC電源,ソーラー充電、非接触充電などの動力源としてもよい。 電源 Further, a power supply 104A is mounted on the upper side of the ultrasonic generator 103A, that is, on the base end side. The power supply 104A is also formed in a columnar shape equal to the outer dimensions of the ultrasonic generator 103A, and is mounted concentrically on the base end side of the ultrasonic generator 103A. A switch 105A for turning on and off the supply of power from the power supply 104A to the ultrasonic generator 103A is provided on the base end side of the power supply 104A. Here, the power source 104A may be a power source such as an AC power source, solar charging, or non-contact charging, in addition to a rechargeable battery such as a lithium ion battery or a dry battery.
 そして、割卵機100Aにて卵30の卵殻20の一部を切り取って切断部31にて開口する際には、図7に示す保持具200Aが用いられる。保持具200Aは、卵30の卵殻20の長軸方向を上下方向に向けた状態として保持し、割卵機100Aにて卵殻20に開口部14を形成する際の卵30の位置決めのために用いられるセンタリング用治具である。具体的に、保持具200Aは、卵30の最大径寸法より大きな内径寸法を有する円筒状の筒状部201Aと、筒状部201Aの一端部である底部を閉塞する円盤状の底面部202Aと、筒状部201A内に同心状に取り付けられた略円筒状の位置決め部203Aとを有する。 When a part of the eggshell 20 of the egg 30 is cut out by the egg breaking machine 100A and opened at the cutting part 31, a holder 200A shown in FIG. 7 is used. The holder 200A holds the eggshell 20 of the egg 30 in a state where the long axis direction of the egg 30 is oriented vertically, and is used for positioning the egg 30 when the opening 14 is formed in the eggshell 20 by the egg breaking machine 100A. Centering jig. Specifically, the holder 200A has a cylindrical cylindrical portion 201A having an inner diameter larger than the maximum diameter of the egg 30, a disk-shaped bottom portion 202A for closing a bottom portion which is one end of the cylindrical portion 201A. And a substantially cylindrical positioning portion 203A concentrically mounted in the cylindrical portion 201A.
 筒状部201Aは、卵30の長軸方向の長さ寸法に略等しい高さ寸法を有している。そして、この筒状部201の内側に略円環状の位置決め部203Aが取り付けられている。位置決め部203Aは、外周面を筒状部201Aの内周面に密着させた状態で取り付けられており、筒状部201Aの高さ寸法より小さな高さ寸法を有している。位置決め部203Aは、例えばスポンジ・ゴム・内部に空気が充填された中空なバルーン等の弾性変形可能な弾性体にて形成されており、卵30の長軸方向を上下方向に沿わせた状態での水平方向の最大外径寸法より小さな内径寸法に形成されている。また、位置決め部203Aは、筒状部201Aの内周面における軸方向の略中間位置、すなわち筒状部201Aの底部側の端部より上方に離間させた位置に取り付けられている。さらに、位置決め部203Aの上部には、中心軸方向に向けて下方に傾斜した傾斜面204Aが形成されている。 The cylindrical portion 201A has a height substantially equal to the length of the egg 30 in the long axis direction. A substantially annular positioning portion 203A is mounted inside the cylindrical portion 201. The positioning portion 203A is attached in a state where the outer peripheral surface is in close contact with the inner peripheral surface of the cylindrical portion 201A, and has a height smaller than the height of the cylindrical portion 201A. The positioning portion 203A is made of, for example, a sponge, rubber, or an elastic body that can be elastically deformed, such as a hollow balloon filled with air, and has a state in which the long axis direction of the egg 30 is vertically aligned. Is formed to have an inner diameter smaller than the maximum outer diameter in the horizontal direction. The positioning portion 203A is attached at a substantially middle position in the axial direction on the inner peripheral surface of the cylindrical portion 201A, that is, at a position separated from the bottom-side end of the cylindrical portion 201A. Further, an inclined surface 204A that is inclined downward toward the central axis direction is formed on the upper portion of the positioning portion 203A.
 そして、この傾斜面204Aの下端に連続して案内部205Aが設けられている。この案内部205Aは、傾斜面204Aの傾斜角度より大きな傾斜角度で中心軸方向に向けて傾斜している。また、案内部205Aは、卵30の端部を下方に向けて位置決め部203Aの中心位置に卵30を挿入して位置決めさせる際の、卵30の適切な挿入、すなわち卵30の長軸方向を上下方向に向けて位置決め部203Aの内周面206Aで卵30を保持させて位置決めさせるための卵30の案内を行う誘導面である。このことから、保持具200Aにて卵30の卵殻20の長軸方向を上下方向に向けて保持し正確に位置決めできるから、卵30の卵殻20の気室側の中心位置へ切削刃本体102Aの刃面113Aを押し当てる作業を精度良く正確に行うことができる。よって、卵30の卵殻20に開口部14を形成する作業を精度良く行うことができる。 案 内 A guide portion 205A is provided continuously to the lower end of the inclined surface 204A. The guide portion 205A is inclined toward the central axis at an inclination angle larger than the inclination angle of the inclined surface 204A. In addition, the guide portion 205A is adapted to insert the egg 30 properly at the time of inserting and positioning the egg 30 at the center position of the positioning portion 203A with the end of the egg 30 facing downward, that is, the long axis direction of the egg 30. This guide surface guides the eggs 30 for holding and positioning the eggs 30 on the inner peripheral surface 206A of the positioning portion 203A in the vertical direction. From this, since the long axis direction of the eggshell 20 of the egg 30 can be held vertically by the holder 200A and accurately positioned, the cutting blade body 102A of the cutting blade body 102A is moved to the center position of the egg shell 20 of the egg 30 on the air chamber side. The work of pressing the blade surface 113A can be performed accurately and accurately. Therefore, the operation of forming the opening 14 in the eggshell 20 of the egg 30 can be performed with high accuracy.
 さらに、底面部202Aの上面側の中心位置には、断面凹状の位置合わせ部としての窪み207Aが設けられている。この窪み207Aは、平面視円形状に形成されており、卵30の卵殻20の端部を下方に向け、この卵殻20の長軸方向を上下方向に沿わせた状態で、この卵殻20の端部が嵌合するように、この卵殻20の端部の形状に略等しい形状とされている。また、この窪み207Aは、底面部202Aの中心位置に同心状に形成されている。 Furthermore, a recess 207A is provided at the center position on the upper surface side of the bottom surface portion 202A as an alignment portion having a concave cross section. The depression 207A is formed in a circular shape in a plan view, and the end of the eggshell 20 of the egg 30 is directed downward with the long axis direction of the eggshell 20 oriented vertically. The shape is substantially equal to the shape of the end of the eggshell 20 so that the parts fit. The depression 207A is formed concentrically at the center of the bottom surface 202A.
 次いで、図10に示す割卵機100Bは、切断部31にて切断した台座本体13の一部を、切断部32にて切断して開口し卵殻22、すなわち台座部12を形成するための切削装置である。割卵機100Bは、主として切削刃本体102Bの外形寸法が異なる点が、上述した割卵機100Aと相違するものの、その他の構成は同様である。 Next, the egg breaking machine 100 </ b> B shown in FIG. 10 cuts a part of the pedestal main body 13 cut at the cutting part 31 by cutting it at the cutting part 32 and opens it to form the eggshell 22, that is, the cutting for forming the pedestal part 12. Device. The egg breaking machine 100B differs from the above-described egg breaking machine 100A mainly in that the outer dimensions of the cutting blade main body 102B are different, but other configurations are the same.
 割卵機100Bの切削刃本体102Bは、切削刃本体102Aの外形寸法より小さく、卵殻22の切断部32の外径寸法に等しい外径寸法を有している。すなわち、切削刃本体102Bの筒状部111Bの一端部に設けられた刃112Bは、切断部32の径寸法に等しい外径寸法となっている。超音波発生装置103Bは、切削刃本体102Bの刃面113Bを台座本体13の表面に押し付けて食い込ませ、台座本体13に円形状の切断部32を形成することに適した所定の周波数の超音波を切削刃本体102Bの少なくとも刃112Bに付与する構成となっている。 The cutting blade body 102B of the egg breaking machine 100B has an outer diameter smaller than the outer diameter of the cutting blade body 102A and equal to the outer diameter of the cut portion 32 of the eggshell 22. That is, the outer diameter of the blade 112B provided at one end of the cylindrical portion 111B of the cutting blade body 102B is equal to the diameter of the cutting portion 32. The ultrasonic generator 103 </ b> B presses the blade surface 113 </ b> B of the cutting blade main body 102 </ b> B into the surface of the pedestal main body 13 to dig into the pedestal main body 13, and forms an ultrasonic wave having a predetermined frequency suitable for forming the circular cut portion 32 in the pedestal main body 13. Is provided to at least the blade 112B of the cutting blade body 102B.
 なお、割卵機100A,100Bのそれぞれにおいて、超音波発生装置103A,103Bから把持本体101A,101Bおよび切削刃本体102A,102Bを取り外し可能とすることにより、これら把持本体101A,101Bおよび切削刃本体102A,102Bの丸洗いが可能となるため、これら把持本体101A,101Bおよび切削刃本体102A,102Bのメンテナンスが容易となる。そして、これら把持本体101A,101Bの取り外し可能な取付構造としては、例えばねじ込み式のほか、2点または3点の爪で係止させる構成、嵌合構造のほか、電磁力を電子制御して取り付ける構造などが可能である。また、これら割卵機100A,100Bから切削刃本体102A,102Bを取り外し、これら切削刃本体102A,102Bの代わりに、工作用のカッター、美顔器、染み抜き器、包丁(ケーキ用、魚用、冷凍食品切断用など)の、超音波振動を用いた種々のアタッチメントを取り付けることもできる。 In each of the egg breaking machines 100A and 100B, the grip main bodies 101A and 101B and the cutting blade main bodies 102A and 102B can be detached from the ultrasonic generators 103A and 103B, so that the grip main bodies 101A and 101B and the cutting blade main body can be removed. Since it is possible to wash the whole of the gripping bodies 102A and 102B, the maintenance of these gripping main bodies 101A and 101B and the cutting blade main bodies 102A and 102B becomes easy. Examples of the detachable mounting structure of the grip main bodies 101A and 101B include, for example, a screw-in type, a configuration in which two or three claws are engaged, a fitting structure, and an electronically controlled electromagnetic force. Structures and the like are possible. Also, the cutting blade bodies 102A and 102B are removed from the egg breaking machines 100A and 100B, and instead of the cutting blade bodies 102A and 102B, a cutter for work, a facial device, a stain remover, and a kitchen knife (for cake, fish, and frozen) Various attachments using ultrasonic vibration (for cutting food, etc.) can also be attached.
 そして、割卵機100Bにて台座本体13を切断部32にて開口する際には、図14に示す保持具200Bが用いられる。この保持具200Bもまた、主として筒状部201Bおよび位置決め部203Bの径寸法が異なる点が、上述した保持具200Aと相違するものの、その他の構成は同様である。保持具200Bの筒状部201Bは、台座本体13の外形寸法、すなわち切断部32の径寸法に等しい内径寸法に形成されている。底面部202Bは、筒状部201Bの底部に対して取り外し可能に取り付けられており、筒状部201Bから取り外した底面部202B上に台座本体13を載置させた状態で、筒状部201Bの底部側に底面部202Bを取り付けることによって、保持具200Bの底面部202B上に台座本体13が保持される構成となっている。 Then, when opening the pedestal main body 13 at the cutting portion 32 in the egg breaking machine 100B, a holder 200B shown in FIG. 14 is used. This holder 200B also differs from the above-described holder 200A mainly in that the cylindrical portion 201B and the positioning portion 203B have different diameters, but the other configurations are the same. The cylindrical portion 201B of the holder 200B is formed to have an outer diameter of the pedestal main body 13, that is, an inner diameter equal to the diameter of the cut portion 32. The bottom portion 202B is detachably attached to the bottom of the cylindrical portion 201B, and the base body 13 is placed on the bottom portion 202B removed from the cylindrical portion 201B. By attaching the bottom surface portion 202B to the bottom side, the pedestal main body 13 is held on the bottom surface portion 202B of the holder 200B.
 また、位置決め部203Bは、割卵機100Bの切削刃本体102Bの外径寸法に略等しい内径寸法とされている。よって、位置決め部203Bは、この位置決め部203Bの中心位置に割卵機100Bの切削刃本体102Bを挿入して位置決めさせることにより、この切削刃本体102Bの刃112Bの中心が台座本体13の中心に位置するように切削刃本体102Bを案内するためのものである。 位置 決 め The positioning portion 203B has an inner diameter substantially equal to the outer diameter of the cutting blade body 102B of the egg breaking machine 100B. Therefore, the positioning portion 203B inserts and positions the cutting blade body 102B of the egg breaking machine 100B at the center position of the positioning portion 203B so that the center of the blade 112B of the cutting blade body 102B becomes the center of the base body 13. This is for guiding the cutting blade body 102B to be positioned.
 次に、このように構成された割卵機100A,100B、および保持具200A,200Bを用いた容器10の製造方法について説明する。 Next, a method of manufacturing the container 10 using the egg breaking machines 100A and 100B and the holders 200A and 200B configured as described above will be described.
 まず、卵30の端部を下方に向けた状態とし、この状態で、卵30を保持具200Aの位置決め部203Aの中心位置に挿入していく。このとき、保持具200Aの位置決め部203Aの案内部205Aによって、卵30の位置決め部203Aへの挿入が案内され、図7に示すように、卵30の長軸方向を上下方向に向けた状態として保持具200Aの位置決め部203Aにて卵30が保持されて位置決めされる。このことから、卵30の卵殻20の気室側の中心と切削刃本体102Aの刃112Aの中心との位置合わせを容易にでき、この卵30の卵殻20の気室側の中心位置への切削刃本体102Aの刃112Aの押し当てを精度良く正確に行うことができる。よって、卵30の卵殻20に開口部14を形成する開口作業を精度良く行うことができる。 First, the end of the egg 30 is directed downward, and in this state, the egg 30 is inserted into the center position of the positioning portion 203A of the holder 200A. At this time, the insertion of the egg 30 into the positioning portion 203A is guided by the guide portion 205A of the positioning portion 203A of the holder 200A, and the long axis direction of the egg 30 is turned up and down as shown in FIG. The egg 30 is held and positioned by the positioning portion 203A of the holder 200A. From this, the center of the egg shell 20 of the egg 30 on the air chamber side and the center of the blade 112A of the cutting blade body 102A can be easily aligned, and the egg 30 is cut to the center position of the egg shell 20 on the air chamber side. The pressing of the blade 112A of the blade main body 102A can be performed accurately and accurately. Therefore, the opening operation for forming the opening 14 in the eggshell 20 of the egg 30 can be performed with high accuracy.
 次いで、割卵機100Aのスイッチ105Aをオンして超音波発生装置103Aにて切削刃本体102Aを超音波振動させる。この状態で、作業者が割卵機100Aの把持本体101Aを把持し、この割卵機100Aの切削刃本体102Aの刃112Aの中心を、図7に示すように、卵30の気室側の中心に合わせるようにして、この切削刃本体102Aをゆっくりと周方向に回しながら、この切削刃本体102Aの刃面113Aを卵30の卵殻20の表面に押し付けて食い込ませていき、切削刃本体102Aの超音波振動にて卵殻20を切断部31で切断する。 Next, the switch 105A of the egg breaking machine 100A is turned on, and the cutting blade body 102A is ultrasonically vibrated by the ultrasonic generator 103A. In this state, the operator grips the grip body 101A of the egg breaking machine 100A, and centers the blade 112A of the cutting blade body 102A of the egg breaking machine 100A on the air chamber side of the egg 30 as shown in FIG. While rotating the cutting blade main body 102A slowly in the circumferential direction so as to align with the center, the blade surface 113A of the cutting blade main body 102A is pressed against the surface of the eggshell 20 of the egg 30 to bite the cutting blade main body 102A. The eggshell 20 is cut at the cutting portion 31 by the ultrasonic vibration of.
 このとき、切削刃本体102Aの刃面113Aが卵殻20に食い込んだ際には、これら刃面113Aの根元部分に設けた逃げ部115Aにより、卵殻20に食い込んだ箇所での切削部分の開きが抑えられ、刃面113Aが卵殻20へ食い込んだ部分に与える反力が分散され、卵殻20へ刃面113Aが食い込んだ部分での卵殻20の割れが抑制される。 At this time, when the blade surface 113A of the cutting blade main body 102A bites into the eggshell 20, the escape portion 115A provided at the root portion of the blade surface 113A suppresses the opening of the cut portion at the portion that has cut into the eggshell 20. Thus, the reaction force applied to the portion where the blade surface 113A cuts into the eggshell 20 is dispersed, and the cracking of the eggshell 20 at the portion where the blade surface 113A cuts into the eggshell 20 is suppressed.
 この結果、割卵機100Aによる卵30の卵殻20の切削作業により、短時間、長くても数秒で卵30の卵殻20から本体部11と台座本体13とが形成される。 As a result, the main body 11 and the pedestal main body 13 are formed from the eggshell 20 of the egg 30 in a short time, at most a few seconds, by the cutting operation of the egg shell 20 of the egg 30 by the egg breaking machine 100A.
 さらに、保持具200Bの底面部202Bを筒状部201Bから取り外し、この筒状部201Bから取り外した底面部202B上に、切断部31側を下方に向けた状態として台座本体13を載置させる。この後、図10に示すように、台座本体13を載置させた底面部202Bを筒状部201Bの底部側に取り付ける。 Furthermore, the bottom part 202B of the holder 200B is detached from the cylindrical part 201B, and the pedestal main body 13 is placed on the bottom part 202B detached from the cylindrical part 201B with the cut part 31 side downward. Thereafter, as shown in FIG. 10, the bottom surface 202B on which the pedestal main body 13 is placed is attached to the bottom of the tubular portion 201B.
 そして、割卵機100Bのスイッチ105Bをオンして超音波発生装置103Bにて切削刃本体102Bを超音波振動させるとともに、作業者が割卵機100Bの把持本体101Bを把持し、この割卵機100Bの切削刃本体102Bの刃112Bを、図10に示すように、保持具200Bの位置決め部203Bに挿入していく。 Then, the switch 105B of the egg breaking machine 100B is turned on to ultrasonically vibrate the cutting blade body 102B with the ultrasonic generator 103B, and the operator grips the gripping body 101B of the egg breaking machine 100B. As shown in FIG. 10, the blade 112B of the cutting blade main body 102B of 100B is inserted into the positioning portion 203B of the holder 200B.
 このとき、保持具200Bの位置決め部203Bの案内部205Bによる案内によって、切削刃本体102Bの刃112Bの中心が台座本体13の中心上となるように位置合わせされる。そして、保持具200Bの位置決め部203Bにて位置合わせされた状態で、切削刃本体102Bの刃面113Bを台座本体13の表面に押し付けて食い込ませていき、切削刃本体102Bの超音波振動にて台座本体13を切断部32で切断する。このとき、切削刃本体102Bの刃面113Bが台座本体13に食い込んだ際には、これら刃面113Bの根元部分に設けた逃げ部115Bによって、刃面113Bが食い込んだ部分での台座本体13の割れが抑制される。 と き At this time, the positioning of the blade 112B of the cutting blade body 102B is aligned with the center of the pedestal body 13 by the guide of the positioning part 203B of the holder 200B by the guide part 205B. Then, in a state where the positioning is performed by the positioning portion 203B of the holder 200B, the blade surface 113B of the cutting blade main body 102B is pressed against the surface of the pedestal main body 13 so as to be bitten, and by the ultrasonic vibration of the cutting blade main body 102B. The pedestal main body 13 is cut by the cutting section 32. At this time, when the blade surface 113B of the cutting blade main body 102B bites into the pedestal main body 13, the escape portion 115B provided at the root portion of the blade surface 113B causes the pedestal main body 13 at the portion where the blade surface 113B bites. Cracks are suppressed.
 この結果、割卵機100Bによる台座本体13の切削作業により、短時間、長くても数秒で卵殻23と台座部12が形成される。 As a result, the eggshell 23 and the pedestal portion 12 are formed in a short time, at most a few seconds, by cutting the pedestal body 13 by the egg breaking machine 100B.
 したがって、例えば飲食店や家庭等であっても、各割卵機100A,100Bの把持本体101A、101Bを把持して切削刃本体102A,102Bを押し当てるという簡単な作業で、卵30の卵殻20を切断部31,32にて容易に開口させることができる。よって、一部を開口した卵殻20を気軽に容器10として用いることができるため、卵殻20を開口して容器10として用いるための割卵機100A,100Bの使い勝手を向上できる。 Therefore, for example, even in a restaurant or a home, the eggshell 20 of the egg 30 can be easily processed by gripping the grip bodies 101A and 101B of the egg breaking machines 100A and 100B and pressing the cutting blade bodies 102A and 102B. Can be easily opened at the cutting portions 31 and 32. Therefore, since the eggshell 20 with a part opened can be used easily as the container 10, the usability of the egg breaking machines 100A and 100B for opening the eggshell 20 and using it as the container 10 can be improved.
 なお、まず割卵機100Bにて卵30の卵殻20の気室側の中心位置を切断部32にて切断して卵殻23を切除してから、この卵殻20の切断部32が設けられた側を割卵機100Aにて切断部31にて切断して、台座本体13を形成することなく、本体部11および台座部12を形成してもよい。 In addition, first, the center position of the egg shell 20 of the egg 30 on the air chamber side is cut by the cutting portion 32 to cut off the eggshell 23 by the egg breaking machine 100B, and then the side of the eggshell 20 where the cut portion 32 is provided. May be cut at the cutting portion 31 by the egg breaking machine 100A to form the main body portion 11 and the pedestal portion 12 without forming the pedestal main body 13.
 さらに、ハンディタイプの割卵機100A,100Bをより高い耐久性にすることによって、商業用利用(洋菓子店・学校教育など)を実現し、それを複数配置することで産業用割卵(菓子業務・卵液業務・マヨネーズ業務)の、サスティナビリティな割卵および容器10となる本体部11と台座部12とを、同時に大量生産が実現でき、廃棄される卵殻20を極限まで減らし、また、卵30の持つ自然の意匠美を容器10の本体部11および台座部12として産業用に再活用できる。産業用は、卵30の卵殻20の上側から割卵機100A、100Bを当てて吸引するなどして卵液を取り出すだけでなく、これら割卵機100A、100Bを卵殻20の下方からを当てて、重力にて卵液を落とし、卵黄と卵白とを分離するための機構とすることもできる。産業用においては、もう一つの吸引機構によって、卵液そのものや、卵液と卵黄との分離機への投入を実施する導線ともなり得る。 Further, by making the handy-type egg breaking machines 100A and 100B more durable, commercial use (such as a confectionery store and school education) is realized, and by arranging a plurality of the same, industrial egg breaking (confectionery business).・ Egg fluid business ・ Mayonnaise business), the mass production of the main body 11 and the pedestal portion 12, which become the sustainable egg breaking and container 10, can be realized at the same time, and the eggshell 20 to be discarded is reduced to the utmost. The natural beauty of the design 30 can be reused for industrial purposes as the main body 11 and the pedestal 12 of the container 10. In the industrial use, not only the egg breaking machines 100A and 100B are applied from above the eggshell 20 of the egg 30 and sucked to take out the egg liquid, but also the egg breaking machines 100A and 100B are applied from below the eggshell 20 by suction. Alternatively, a mechanism for dropping egg fluid by gravity and separating egg yolk and egg white can also be used. In the industrial use, another suction mechanism can be used as the egg fluid itself or as a conducting wire for feeding the egg fluid and the yolk into the separator.

 次に、図11を参照して、本発明のさらに他の実施形態の割卵機100Cについて詳細に説明する。なお、以下の説明においても、適宜図1ないし図4を参照する。
(Ultrasonic breaking machine: Double type)
Next, an egg breaking machine 100C according to still another embodiment of the present invention will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る割卵機100Cは、上述した割卵機100A,100Bとは異なり、切断部31用の大径な切削刃本体102Aと、切断部32用の小径な切削刃本体102Bとが二重に取り付けられた構成となっている。すなわち、切削刃本体102Aの内側に切削刃本体102Bが同心状に取り付けられている。切削刃本体102Aは、切削刃本体102Bの長さ寸法より大きな長さ寸法とされており、切削刃本体102Aの刃面113Aよりも内側に、切削刃本体102Bの刃面113Bが隠れるように、これら刃面113A,113Bの高さ位置が調整されている。 Unlike the egg breaking machines 100A and 100B described above, the egg breaking machine 100C according to the present embodiment includes a large-diameter cutting blade body 102A for the cutting portion 31 and a small-diameter cutting blade body 102B for the cutting portion 32. It has a double mounted configuration. That is, the cutting blade body 102B is mounted concentrically inside the cutting blade body 102A. The cutting blade body 102A has a length dimension larger than the length dimension of the cutting blade body 102B, and the blade surface 113B of the cutting blade body 102B is hidden inside the blade surface 113A of the cutting blade body 102A. The height positions of these blade surfaces 113A and 113B are adjusted.
 超音波発生装置103Cは、切削刃本体102Aによる切断部31の形成に適した所定の周波数の超音波を切削刃本体102Aに付与する第1超音波発生部131と、切削刃本体102Bによる切断部32の形成に適した所定の周波数の超音波を切削刃本体102Bに付与する第2超音波発生部132とを備えている。そして、電源104Cは、第1超音波発生部131および第2超音波発生部132への電力の供給が可能とされている。電源104cの上面には、電源104Cから第1超音波発生部131および第2超音波発生部132への電力の供給をオンオフさせるスイッチ105Cと、これら第1超音波発生部131および第2超音波発生部132のいずれかへの電力の供給を切り換える切換スイッチ133が設けられている。 The ultrasonic generator 103C includes a first ultrasonic generator 131 that applies ultrasonic waves having a predetermined frequency suitable for forming the cutting section 31 by the cutting blade body 102A to the cutting blade main body 102A, and a cutting section formed by the cutting blade main body 102B. And a second ultrasonic generator 132 that applies ultrasonic waves having a predetermined frequency suitable for forming the main body 32 to the cutting blade main body 102B. The power supply 104C is capable of supplying power to the first ultrasonic generator 131 and the second ultrasonic generator 132. On the upper surface of the power supply 104c, a switch 105C for turning on / off the supply of power from the power supply 104C to the first ultrasonic generation unit 131 and the second ultrasonic generation unit 132, and the first ultrasonic generation unit 131 and the second ultrasonic generation unit A changeover switch 133 that switches the supply of power to any of the generators 132 is provided.
 したがって、割卵機100Cのスイッチ105Cをオンするとともに切換スイッチ133を操作して第2超音波発生部132へ電力を供給し、この第2超音波発生部132にて切削刃本体102Bを超音波振動させてから、作業者が割卵機100Cの切削刃本体102A側の把持本体101Aを把持する。そして、切削刃本体102Aの刃112Aの中心を、卵30の気室側の中心に位置合わせし、この状態で、内側の切削刃本体102Bの刃面113Bを卵30の卵殻20の表面に押し付けて食い込ませていき、切削刃本体102Bの超音波振動にて卵殻20を切断部32で切断する。 Therefore, the switch 105C of the egg breaking machine 100C is turned on, and at the same time, the changeover switch 133 is operated to supply electric power to the second ultrasonic generator 132. After the vibration, the operator grips the grip body 101A on the cutting blade body 102A side of the egg breaking machine 100C. Then, the center of the blade 112A of the cutting blade body 102A is aligned with the center of the egg 30 on the air chamber side, and in this state, the blade surface 113B of the inner cutting blade body 102B is pressed against the surface of the eggshell 20 of the egg 30. The eggshell 20 is cut by the cutting portion 32 by ultrasonic vibration of the cutting blade body 102B.
 次いで、切断部32にて卵殻20が切断された後、切換スイッチ133を操作して第2超音波発生部132への電力の供給を停止させ切削刃本体102Bの超音波振動を停止させるとともに、第1超音波発生部131へ電力を供給し、この第1超音波発生部131にて切削刃本体102Aを超音波振動さる。そして、切削刃本体102Bを卵殻20内にさらに食い込ませていき、外側の切削刃本体102Aの刃面113Aを卵30の卵殻20の表面に押し付けて食い込ませ、切削刃本体102Aの超音波振動にて卵殻20を切断部32で切断する。 Next, after the eggshell 20 is cut by the cutting unit 32, the changeover switch 133 is operated to stop the supply of power to the second ultrasonic generating unit 132 to stop the ultrasonic vibration of the cutting blade body 102 </ b> B, Power is supplied to the first ultrasonic generator 131, and the first ultrasonic generator 131 ultrasonically vibrates the cutting blade body 102A. Then, the cutting blade main body 102B is further cut into the eggshell 20, and the blade surface 113A of the outer cutting blade main body 102A is pressed against the surface of the eggshell 20 of the egg 30 to cause the cutting blade main body 102A to vibrate. The eggshell 20 is cut at the cutting portion 32.
 この結果、割卵機100Cの切削刃本体102A,102Bによる卵殻20の切削作業によって、本体部11および台座部12が形成される。したがって、割卵機102Cの切削刃本体102Aを用いることで卵殻20から本体部11および台座本体13を形成でき、この割卵機100Cの切削刃本体102Bを用いることで台座本体13から台座部12を形成できる。よって、外径寸法の異なる切削刃本体102A,102Bを有した複数、例えば2台の割卵機を用いることなく、1台の割卵機100Cのみで、卵20の卵殻20から本体部11、台座本体13および台座部12のそれぞれを形成できるので、割卵機100Cの使い勝手を向上できる。 As a result, the body 11 and the pedestal 12 are formed by the cutting operation of the eggshell 20 by the cutting blade bodies 102A and 102B of the egg breaking machine 100C. Therefore, by using the cutting blade body 102A of the egg breaking machine 102C, the main body 11 and the pedestal body 13 can be formed from the eggshell 20. By using the cutting blade body 102B of the egg breaking machine 100C, the pedestal body 13 and the pedestal portion 12 can be formed. Can be formed. Therefore, without using a plurality of, for example, two egg breaking machines having cutting blade bodies 102A, 102B having different outer diameters, only one egg breaking machine 100C is used to move the eggshell 20 of the egg 20 to the main body 11, Since each of the pedestal main body 13 and the pedestal portion 12 can be formed, the usability of the egg breaking machine 100C can be improved.
(超音波割卵機:ケース型)
 次に、図12を参照して、さらに他の実施形態の割卵機100Dについて詳細に説明する。なお、以下の説明においても、適宜図1ないし図4を参照する。
(Ultrasonic egg breaking machine: case type)
Next, an egg breaking machine 100D of still another embodiment will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る割卵機100Dは、上述した割卵機100Aとは異なり、切削刃本体102Aの外周に把持本体となるケース体101Dが取り付けられた構成となっている。ケース体101Dは、切削刃本体102Aの外周を覆うように、この切削刃本体102Aの同心状に取り付けられている。そして、ケース体101Dは、切削刃本体102Aの外径寸法より大きく、卵30の長軸方向に直交する径方向の最大外径寸法より大きな内径寸法を有している。また、ケース体101Dは、切削刃本体102Aの長さ寸法より小さな長さ寸法を有した円筒状に形成されている。したがって、切削刃本体102Aの刃112Aは、ケース体101Dの一端部よりも一端側に突出した状態として取り付けられている。 卵 The egg breaking machine 100D according to the present embodiment is different from the above-described egg breaking machine 100A in that a case body 101D serving as a grip body is attached to the outer periphery of the cutting blade body 102A. The case body 101D is attached concentrically to the cutting blade body 102A so as to cover the outer periphery of the cutting blade body 102A. The case body 101D has an inner diameter larger than the outer diameter of the cutting blade body 102A and larger than the maximum outer diameter in the radial direction orthogonal to the long axis direction of the egg 30. The case body 101D is formed in a cylindrical shape having a length dimension smaller than the length dimension of the cutting blade body 102A. Therefore, the blade 112A of the cutting blade main body 102A is attached so as to protrude from the one end of the case body 101D to one end.
 すなわち、切削刃本体102Aをケース体101Dで覆う構成としたことにより、切削刃本体102Aを超音波振動させた際の振動がケース体101Dを把持する作業者の手に伝わりにくくなる。したがって、割卵機100Dを長時間に亘って連続して使用した場合に生じ得る、人体への悪影響を防止できる。 That is, since the cutting blade main body 102A is configured to be covered with the case body 101D, the vibration when the cutting blade main body 102A is ultrasonically vibrated is less likely to be transmitted to the hand of the worker holding the case body 101D. Therefore, it is possible to prevent the human body from being adversely affected, which may occur when the egg breaking machine 100D is used continuously for a long time.
 超音波発生装置103Dは、ケース体101Dの外径寸法に等しい外径寸法を有する円柱状に形成されており、このケース体101Dの基端側に同心状に取り付けられている。電源104Dは、超音波発生装置103Dの外形寸法に等しい円柱状に形成されており、この超音波発生装置103Dの基端側に同心状に取り付けられている。また、この電源104Dの基端側には、電源104Dから超音波発生装置103Dへの電力の供給をオンオフさせるスイッチ105Aが設けられている。 The ultrasonic generator 103D is formed in a cylindrical shape having an outer diameter dimension equal to the outer diameter dimension of the case body 101D, and is attached concentrically to the base end side of the case body 101D. The power supply 104D is formed in a columnar shape equal to the outer dimensions of the ultrasonic generator 103D, and is mounted concentrically on the base end side of the ultrasonic generator 103D. A switch 105A for turning on and off the supply of power from the power supply 104D to the ultrasonic generator 103D is provided at the base end of the power supply 104D.
 したがって、割卵機100Dのスイッチ105Aをオンし超音波発生装置103Dにて切削刃本体102Aを超音波振動させてから、作業者が割卵機100Dのケース体101Dを把持し、切削刃本体102Aの刃112Aの中心を、卵30の気室側の中心に位置合わせし、この状態で、切削刃本体102Aの刃112Aを卵30の卵殻20の表面に押し付けて食い込ませていくことにより、切削刃本体102Aの超音波振動にて卵殻20を切断部31で切断できる。このことから、割卵機100Dの切削刃本体102Aによる卵殻20の切削作業によって、本体部11と台座本体13とが形成される。 Therefore, after the switch 105A of the egg breaking machine 100D is turned on and the cutting blade body 102A is ultrasonically vibrated by the ultrasonic generator 103D, the operator grips the case body 101D of the egg breaking machine 100D, and the cutting blade body 102A. The center of the blade 112A of the egg 30 is aligned with the center of the air chamber side of the egg 30, and in this state, the blade 112A of the cutting blade body 102A is pressed against the surface of the eggshell 20 of the egg 30 to cut it. The eggshell 20 can be cut at the cutting portion 31 by the ultrasonic vibration of the blade main body 102A. From this, the main body 11 and the pedestal main body 13 are formed by the cutting operation of the eggshell 20 by the cutting blade main body 102A of the egg breaking machine 100D.
 なお、割卵機100Dの切削刃本体102Aの代わりに、切断部32用の切削刃本体102Bとしても良い。この場合は、割卵機100Dによる台座本体13の切断作業によって、台座本体13を切断部32にて切断でき、台座部12を形成できる。 Instead of the cutting blade body 102A of the egg breaking machine 100D, a cutting blade body 102B for the cutting section 32 may be used. In this case, the pedestal main body 13 can be cut by the cutting section 32 by the cutting operation of the pedestal main body 13 by the egg breaking machine 100D, and the pedestal portion 12 can be formed.

(Ultrasonic egg breaking machine: only blade is separate type)
Next, an egg breaking machine 100E of still another embodiment will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る割卵機100Eは、切削刃本体102A,102Bをそれぞれ有し、第1超音波発生部131および第2超音波発生部132を有する超音波発生装置103Eが切削刃本体102A,102Bと別体とされた構成となっている。各切削刃本体102A,102Bの基端側には円盤状の把持本体101A,101Bが同心状に取り付けられている。これら把持本体101A,101Bには、それぞれコード134が接続されており、これらコード134を介して、各切削刃本体102A,102Bが超音波発生装置103Eに接続されている。 The egg breaking machine 100E according to the present embodiment has cutting blade main bodies 102A and 102B, respectively, and an ultrasonic generator 103E having a first ultrasonic generator 131 and a second ultrasonic generator 132 has a cutting blade main body 102A, It has a configuration separate from 102B. Disk-shaped gripping bodies 101A, 101B are concentrically attached to the base ends of the cutting blade bodies 102A, 102B. A cord 134 is connected to each of the gripping bodies 101A and 101B, and the cutting blade bodies 102A and 102B are connected to the ultrasonic generator 103E via these cords 134.
 そして、超音波発生装置103Eには、電源104Eから第1超音波発生部131および第2超音波発生部132への電力の供給をオンオフさせるスイッチ105Eと、これら第1超音波発生部131および第2超音波発生部132のいずれかへの電力の供給を切り換える切換スイッチ133Eが設けられている。 The ultrasonic generator 103E includes a switch 105E for turning on and off the supply of power from the power supply 104E to the first ultrasonic generator 131 and the second ultrasonic generator 132, and a switch 105E for connecting the first ultrasonic generator 131 and the A changeover switch 133E is provided for switching the supply of power to any one of the two ultrasonic generators 132.
 よって、超音波発生装置103Eのスイッチ105Eをオンするとともに切換スイッチ133Eを操作して第1超音波発生部131へ電力を供給し、この第1超音波発生部131からの切削刃本体102Aの超音波振動によって、卵30の卵殻20を切断部31にて切断することができる。また、超音波発生装置103Eのスイッチ105Eをオンした状態で切換スイッチ133Eを操作して第2超音波発生部132へ電力を供給し、この第2超音波発生部132からの切削刃本体102Bの超音波振動によって、卵殻20または台座本体13を切断部32にて切断できる。したがって、割卵機100Eによる卵殻20の切断作業によって、本体部11および台座部12を形成できる。 Therefore, the switch 105E of the ultrasonic generator 103E is turned on, and at the same time, the changeover switch 133E is operated to supply power to the first ultrasonic generator 131. The eggshell 20 of the egg 30 can be cut at the cutting portion 31 by the sonic vibration. In addition, while the switch 105E of the ultrasonic generator 103E is turned on, the changeover switch 133E is operated to supply electric power to the second ultrasonic generator 132, and the cutting blade body 102B from the second ultrasonic generator 132 is turned on. The eggshell 20 or the pedestal main body 13 can be cut at the cutting portion 32 by ultrasonic vibration. Therefore, the main body 11 and the pedestal 12 can be formed by the cutting operation of the eggshell 20 by the egg breaking machine 100E.

Next, an egg breaking machine 100F of still another embodiment will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る割卵機100Fは、超音波発生装置103Fの一端側に切削刃本体102Aが取り付けられ、超音波発生装置103Fの他端側に電源104Fが取り付けられ、この電源104Fの他端側に切削刃本体102Bが取り付けられた構成となっている。これら切削刃本体102A,102Bは、同軸状となるように相対する方向に突出するように取り付けられている。切削刃本体102Bの外周には、この切削刃本体102Bを覆うように把持本体となるケース体101Fが同心状に取り付けられている。このケース体101Fは、切断部31の径寸法より小さな外径寸法に形成されている。 In the egg breaking machine 100F according to the present embodiment, a cutting blade main body 102A is attached to one end of an ultrasonic generator 103F, a power supply 104F is attached to the other end of the ultrasonic generator 103F, and the other end of the power supply 104F. The cutting blade body 102B is attached to the side. These cutting blade bodies 102A and 102B are attached so as to protrude in opposite directions so as to be coaxial. A case body 101F serving as a grip body is concentrically attached to the outer periphery of the cutting blade body 102B so as to cover the cutting blade body 102B. The case body 101F is formed to have an outer diameter smaller than the diameter of the cutting portion 31.
 そして、超音波発生装置103Fは、第1超音波発生部131および第2超音波発生部132を有しており、電源104Fには、電源104Eから第1超音波発生部131および第2超音波発生部132への電力の供給をオンオフさせるスイッチ105Fと、これら第1超音波発生部131および第2超音波発生部132のいずれかへの電力の供給を切り換える切換スイッチ133Fとが設けられている。 The ultrasonic generator 103F has a first ultrasonic generator 131 and a second ultrasonic generator 132, and a power supply 104F receives a first ultrasonic generator 131 and a second ultrasonic generator from a power supply 104E. A switch 105F for turning on and off the supply of power to the generator 132 and a changeover switch 133F for switching the supply of power to one of the first ultrasonic generator 131 and the second ultrasonic generator 132 are provided. .
 したがって、切削刃本体102Aの超音波振動によって、卵30の卵殻20を切断部31にて切断でき、割卵機100Fの上下を反転させることにより、切削刃本体102Bの超音波振動によって、卵殻20または台座本体13を切断部32にて切断できるため、割卵機100Fによる卵殻20の切断作業によって、本体部11および台座部12を形成できる。 Therefore, the eggshell 20 of the egg 30 can be cut by the ultrasonic vibration of the cutting blade main body 102A at the cutting section 31, and the eggshell 20 can be cut by the ultrasonic vibration of the cutting blade main body 102B by turning the egg breaking machine 100F upside down. Alternatively, since the pedestal main body 13 can be cut by the cutting portion 32, the main body 11 and the pedestal portion 12 can be formed by cutting the eggshell 20 by the egg breaking machine 100F.

And an ultrasonic generator 103G for ultrasonic vibration. The cutting blade group 140 has a rectangular flat plate-like support plate 141, and the cutting blade main bodies 102A are attached to the lower surface of the support plate 141 at regular intervals in a lattice shape. Each of the cutting blade main bodies 102A is arranged in a state where the axial direction of each cutting blade main body 102A is arranged in parallel, and is attached to the lower surface of the support plate 141 so as to protrude.
 切削刃群140の支持板141の長手方向の両側部には、この支持板141を水平な状態で上下動、すなわち昇降駆動させる一対のフレーム142が取り付けられている。このフレーム142には、切削刃群140の支持板141を昇降駆動させるための駆動装置であるモータ143と、超音波発生装置103Gと、これらモータ143および超音波発生装置103Gに電力を供給するための電源104Gと、が取り付けられている。 一 対 A pair of frames 142 for vertically moving the support plate 141 in a horizontal state, that is, for vertically driving the support plate 141 is attached to both longitudinal sides of the support plate 141 of the cutting blade group 140. The frame 142 has a motor 143 as a driving device for driving the support plate 141 of the cutting blade group 140 up and down, an ultrasonic generator 103G, and an electric power supply to the motor 143 and the ultrasonic generator 103G. And a power supply 104G.
 一方、切削刃群140の下面に対応する位置には、複数、例えば計8個の卵30を並べて位置決め保持する保持装置としての保持具200Gが設置されている。この保持具200Gは、切削刃群140の支持板141とほぼ同じ大きさの矩形平板状の保持板145を備え、保持板145の上面に卵30が等間隔に格子状に位置決め保持可能な構成となっている。すなわち、この保持具200Gは、この保持具200Gにて保持した各卵30の中心に、切削刃群140の各切削刃本体102Aの刃112Aが食い込むように、これら複数の切削刃本体102Aの刃112Aの中心に対向する位置に、各卵30の長軸方向を上下方向に沿わせた状態で保持できるように構成されている。そして、この保持具200Gは、一対のフレーム142間に取り付けられている。 On the other hand, at a position corresponding to the lower surface of the cutting blade group 140, a holder 200G as a holding device for arranging and holding a plurality, for example, a total of eight eggs 30, is installed. The holder 200G includes a rectangular flat holding plate 145 having substantially the same size as the support plate 141 of the cutting blade group 140, and the eggs 30 can be positioned and held on the upper surface of the holding plate 145 at regular intervals in a lattice shape. It has become. That is, the holder 200G has a plurality of blades 102A of the plurality of cutting blade bodies 102A so that the blade 112A of each cutting blade body 102A of the cutting blade group 140 bites into the center of each egg 30 held by the holder 200G. Each egg 30 is configured to be held at a position facing the center of 112A in a state where the long axis direction of each egg 30 is vertically aligned. The holder 200G is mounted between the pair of frames 142.
 したがって、保持具200Gの保持板145上に、卵30の長軸方向を上下方向に沿わせた状態で卵30を並べて保持させる。そして、電源104Gから超音波発生装置103Gに電力を供給して、この超音波発生装置103Gにて各切削刃本体102Aのそれぞれを超音波振動させた状態とする。次いで、電源104Gからモータ143に電力を供給して駆動させて切削刃群140の支持板141を降下させていくことにより、各切削刃本体102Aの刃112Aを卵30の卵殻20の表面に食い込ませることができ、これら切削刃本体102Aの超音波振動によって各卵殻20を切断部31にて切断できる。よって、割卵機100Gの各切削刃本体102Aによる卵殻20の切削作業によって、同時に複数、例えば8個の本体部11および台座本体13が形成される。 Therefore, the eggs 30 are arranged and held on the holding plate 145 of the holder 200G with the long axis direction of the eggs 30 along the vertical direction. Then, power is supplied from the power supply 104G to the ultrasonic generator 103G, and each of the cutting blade bodies 102A is ultrasonically vibrated by the ultrasonic generator 103G. Next, power is supplied to the motor 143 from the power source 104G to drive the motor 143 to lower the support plate 141 of the cutting blade group 140, thereby cutting the blade 112A of each cutting blade main body 102A into the surface of the eggshell 20 of the egg 30. Each eggshell 20 can be cut at the cutting portion 31 by the ultrasonic vibration of the cutting blade body 102A. Therefore, a plurality of, for example, eight main bodies 11 and the pedestal main bodies 13 are simultaneously formed by the cutting operation of the eggshell 20 by each cutting blade main body 102A of the egg breaking machine 100G.
 このことから、一度の超音波発生装置103Gからの各切削刃本体102Aの超音波振動によって、保持具200Gの保持板145上に位置決めされて保持されている複数、例えば8個の卵30の卵殻20のそれぞれに精度良く開口部14を形成できるから、これら複数の卵30の卵殻20の開口作業を精度良く容易にできる。よって、複数の卵30の卵殻20を開口するための割卵機100Gの使い勝手を向上できる。 From this, the eggshell of a plurality of, for example, eight eggs 30 positioned and held on the holding plate 145 of the holder 200G by the ultrasonic vibration of each cutting blade body 102A from the ultrasonic generator 103G once. Since the openings 14 can be formed in each of the eggs 20 with high accuracy, the opening operation of the eggshells 20 of the plurality of eggs 30 can be easily and accurately performed. Therefore, the usability of the egg breaking machine 100G for opening the eggshells 20 of the plurality of eggs 30 can be improved.
 なお、本割卵機100Gの切削刃本体102Aに代えて切削刃本体102Bを取り付けることにより、同時に複数の卵殻20または台座本体13を切断部32にて切断する割卵機とすることも可能である。 In addition, by attaching the cutting blade body 102B instead of the cutting blade body 102A of the present egg breaking machine 100G, it is also possible to make an egg breaking machine that cuts a plurality of eggshells 20 or the pedestal body 13 at the cutting section 32 at the same time. is there.

As shown in FIG. 18, the outer peripheral side of the blade 112I of the cutting blade main body 102I is made thin to form a flat blade surface 113I, and the edge portion 114I inclined at the root of the blade surface 113I is continuously formed in the circumferential direction. May be formed. In this case, the coating layer 302 is formed in the circumferential direction so as to cover the entire blade 112I, that is, from the blade surface 113I to the tip and the inner surface of the blade 112I.
 さらに、把持本体101Hは、円筒状のケース体303を備えており、このケース体303の先端側にモータ301が収容されている。また、このケース体303の基端側には、モータ301を駆動させるための電源104Hが収容されており、このケース体303の外周面には、電源104Hからモータ301への電力の供給をオンオフさせるスイッチ304が設けられている。さらに、ケース体303の先端側には、切削刃本体102Hでの卵殻20の切削時に切削刃本体102Hの内部に生じた卵殻20の切削屑を吸気するための吸気機構400が同心状に取り付けられている。ここで、この吸気機構400もまた、把持本体101Hの一部を構成している。 把持 Furthermore, the grip main body 101H includes a cylindrical case body 303, and a motor 301 is housed at the tip side of the case body 303.

Here, the intake mechanism 400 also forms a part of the grip main body 101H.
 切削刃本体102Hの筒状部111Hの基端側は閉塞されており、この筒状部111Hの基端側には円筒状の回転軸305が同心状に取り付けられている。筒状部111Hの基端側の中心位置には、切削刃本体112Hでの卵30の卵殻20の切削時に切削刃本体102H内に生じた卵殻20の切削屑を吸込むための吸気口306が設けられている。回転軸305は、吸気口306に連通するように中心位置に吸気路307を有する円筒状に形成されている。回転軸305の周面には、吸気口306から吸気路307に吸込んだ切削屑を排気するため排気口308が設けられている。 基 The base end of the cylindrical portion 111H of the cutting blade body 102H is closed, and a cylindrical rotary shaft 305 is concentrically attached to the base end of the cylindrical portion 111H. At a central position on the base end side of the cylindrical portion 111H, an intake port 306 is provided for sucking chips of the eggshell 20 generated in the cutting blade body 102H when the eggshell 20 of the egg 30 is cut by the cutting blade body 112H.

 そして、切削刃本体102Hの回転軸305は、吸気機構400に挿通されて回転可能に取り付けられている。吸気機構400は、円筒状の吸気機構本体401を有し、この吸気機構本体401に切削刃本体112Hの回転軸305が周方向に回転可能に挿通されている。吸気機構本体401には、切削刃本体112Hの回転軸305の排気口308に連通可能な排気路402が設けられている。排気路402は、回転軸305の排気口308に連通するように、吸気機構本体401の径方向に沿って直接状に設けられている。また、吸気機構本体401と回転軸305との間には、ボールベアリング403が取り付けられており、このボールベアリング403は、回転軸305の排気口308からずらした位置、すなわち排気路402を挟んだ両側に設けられている。 回 転 The rotating shaft 305 of the cutting blade body 102H is inserted into the suction mechanism 400 and is rotatably mounted. The intake mechanism 400 has a cylindrical intake mechanism main body 401, and the rotary shaft 305 of the cutting blade main body 112H is inserted through the intake mechanism main body 401 so as to be rotatable in a circumferential direction. The intake mechanism main body 401 is provided with an exhaust path 402 that can communicate with the exhaust port 308 of the rotary shaft 305 of the cutting blade main body 112H. The exhaust path 402 is provided directly along the radial direction of the intake mechanism main body 401 so as to communicate with the exhaust port 308 of the rotating shaft 305.

It is configured to be driven.
 次に、このように構成された割卵機100Hを用いた容器10の製造方法について説明する。 Next, a method of manufacturing the container 10 using the egg breaking machine 100H configured as described above will be described.
 まず、吸気管404の一端を割卵機100Hの吸気接続部405に接続するとともに、この吸気管404の他端を吸気装置に接続する。次いで、吸気装置を駆動させるとともに、割卵機100Hのスイッチ304をオンして電源104Hから電力をモータ301へ供給し、切削刃本体102Hを回転駆動させる。このとき、吸気装置の吸気によって、割卵機100Hの切削刃本体102H内の空気が吸気口306から吸い込まれ、この空気が回転軸305の吸気路307、排気口308、吸気機構400の排気路402、吸気接続部405、および吸気管404へと流れ吸気装置へ吸気されていく。 First, one end of the intake pipe 404 is connected to the intake connection section 405 of the egg breaking machine 100H, and the other end of the intake pipe 404 is connected to the intake device. Next, the intake device is driven, and the switch 304 of the egg breaking machine 100H is turned on to supply electric power from the power source 104H to the motor 301, thereby rotating the cutting blade body 102H. At this time, the air in the cutting blade body 102H of the egg breaking machine 100H is sucked from the air inlet 306 by the air suction of the air suction device, and the air is sucked into the air intake path 307 of the rotary shaft 305, the exhaust port 308, and the exhaust path of the air intake mechanism 400. It flows to 402, the intake connection section 405, and the intake pipe 404, and is taken into the intake device.
 この状態で、作業者が割卵機100Hのケース体303を把持する。そして、切削刃本体102Hの刃112Hの中心を、卵30の気室側の中心に位置合わせし、この状態で、切削刃本体102Hの刃112Hを卵30の卵殻20の表面に押し付けていき、切削刃本体102Hの刃112Hの回転にて卵殻20を研削していき切断部31で切削する。 で In this state, the operator grips the case body 303 of the egg breaking machine 100H. Then, the center of the blade 112H of the cutting blade body 102H is aligned with the center of the egg 30 on the air chamber side, and in this state, the blade 112H of the cutting blade body 102H is pressed against the surface of the eggshell 20 of the egg 30; The eggshell 20 is ground by the rotation of the blade 112H of the cutting blade body 102H and cut by the cutting unit 31.
 このとき、切削刃本体102Hでの卵30の卵殻20の切削時に生じた卵殻20の切削片が、切削刃本体102H内の吸気口306から吸い込まれ、回転軸305の吸気路307、排気口308、吸気機構400の排気路402、吸気接続部405、および吸気管404を介して吸気装置へ吸気されて排気される。よって、切削刃本体102Hにて卵30の卵殻20を切削する時に生じ得る卵殻20内への切削片の侵入を防止できる。したがって、卵30の内容物、すなわち卵黄および卵白への切削片の混入を防止できるから、これら卵黄および卵白の利用を容易にできる。 At this time, a cut piece of the eggshell 20 generated when the eggshell 20 of the egg 30 is cut by the cutting blade body 102H is sucked from the intake port 306 in the cutting blade body 102H, and the intake path 307 and the exhaust port 308 of the rotating shaft 305. The air is sucked into the air intake device via the exhaust path 402 of the air intake mechanism 400, the air intake connection 405, and the air intake pipe 404, and is exhausted. Therefore, it is possible to prevent the cut pieces from entering the eggshell 20 which may occur when the eggshell 20 of the egg 30 is cut by the cutting blade body 102H. Therefore, it is possible to prevent the cut pieces from being mixed into the contents of the egg 30, that is, the egg yolk and the albumen, so that the egg yolk and the albumen can be easily used.
 この結果、割卵機100Hによる卵30の卵殻20の切削作業により、卵30の卵殻20から本体部11と台座本体13とが形成される。したがって、例えば飲食店や家庭等であっても、把持本体101Hを把持した状態で切削刃本体102Hを卵30の卵殻20に押し当てるという簡単な作業で、卵30の卵殻20に開口部14を形成できるから、一部を開口した卵殻20を気軽に容器10として用いることができる。このため、卵30の卵殻20を開口して容器10として用いるための割卵機100Hの使い勝手を向上できる。 As a result, the main body 11 and the pedestal main body 13 are formed from the egg shell 20 of the egg 30 by the cutting operation of the egg shell 20 of the egg 30 by the egg breaking machine 100H. Therefore, for example, even in a restaurant or a home, the opening 14 is formed in the eggshell 20 of the egg 30 by a simple operation of pressing the cutting blade body 102H against the eggshell 20 of the egg 30 while holding the gripping body 101H. Since the eggshell 20 can be formed, the eggshell 20 partially open can be easily used as the container 10. For this reason, the usability of the egg breaking machine 100H for opening the eggshell 20 of the egg 30 and using it as the container 10 can be improved.
 なお、割卵機100Hの切削刃本体102Hを、台座部12の切断部32の径寸法に等しい外径寸法としても良い。この場合は、割卵機100Hによる台座本体13の切断作業によって、台座本体13を切断部32にて切断でき、台座部12を形成できる。またさらに、割卵機100Hの切削刃本体102Hを交換可能とし、台座部12の切断部32の外径寸法に等しい外径寸法の切削刃本体に付け替えることによって、1台の割卵機100Hにて、本体部11および台座部12を形成できる。 The cutting blade body 102H of the egg breaking machine 100H may have an outer diameter equal to the diameter of the cutting portion 32 of the pedestal portion 12. In this case, the pedestal main body 13 can be cut by the cutting portion 32 by the cutting operation of the pedestal main body 13 by the egg breaking machine 100H, and the pedestal portion 12 can be formed. Further, the cutting blade body 102H of the egg breaking machine 100H is made replaceable, and is replaced with a cutting blade body having an outer diameter dimension equal to the outer diameter dimension of the cutting portion 32 of the pedestal section 12, thereby providing one egg breaking machine 100H. Thus, the main body 11 and the base 12 can be formed.
 さらに、割卵機100Hの切削刃本体102Hを交換可能とし、この切削刃本体102Hの代わりに、エッグアートやイースターエッグ作成用の錐や、泡立て器等をアタッチメントとして取り付け可能としてもよい。 Furthermore, the cutting blade body 102H of the egg breaking machine 100H may be replaceable, and instead of the cutting blade body 102H, an egg art, a cone for making Easter eggs, a whisk, or the like may be attached as an attachment.

I have. Specifically, in the egg breaking machine 100J, an elevating mechanism 406 for driving the cutting blade main body 102J to move forward and backward in the axial direction, that is, to elevate and lower it, is attached inside the case body 303 of the grip main body 101J. The lifting mechanism 406 is housed between the motor 301 and the power supply 104J, and is configured to move the drive shaft 309 of the cutting blade body 102J forward and backward in the axial direction. An elevating switch 407 for driving the elevating mechanism 406 and an amount of power supplied from the power source 104J to the motor 301 are adjusted on the outer peripheral surface of the case body 303 of the grip body 101J to adjust the rotation speed of the cutting blade main body 102J. And a speed change switch 408 for adjusting the speed.
 昇降スイッチ407は、基端側を押すことにより、昇降機構406にて切削刃本体102Jを退避、すなわち上昇でき、先端側を押すことにより、昇降機構406にて切削刃本体102Jを進出、すなわち下降できる構成となっている。変速スイッチ408は、この変速スイッチ108を押す圧力に応じて、電源104Jからモータ301への電力の供給量を調整して切削刃本体102Jの回転速度を調整する。要するに、変速スイッチ408を押す力を大きくしていくと、電源104Jからモータ301への電力の供給量が増大していき、切削刃本体102Jの回転速度が高くなっていく。逆に、変速スイッチ408を押す力を小さくしていくと、電源104Jからモータ301への電力の供給量が減少していき、切削刃本体102Jの回転速度が低くなっていく。 The elevating switch 407 can retract the cutting blade body 102J by the elevating mechanism 406 by pushing the base end side, that is, move up, and advance the cutting blade main body 102J by the elevating mechanism 406 by pushing the tip side, that is, descend. It has a configuration that can be used. The speed change switch 408 adjusts the amount of electric power supplied from the power supply 104J to the motor 301 in accordance with the pressure for pressing the speed change switch 108 to adjust the rotation speed of the cutting blade body 102J. In short, as the pressing force of the shift switch 408 is increased, the amount of power supplied from the power source 104J to the motor 301 is increased, and the rotation speed of the cutting blade body 102J is increased. Conversely, when the pressing force of the shift switch 408 is reduced, the amount of power supplied from the power supply 104J to the motor 301 decreases, and the rotation speed of the cutting blade body 102J decreases.
 また、把持本体101Jのケース体303の先端側には、先端側に向けて徐々に縮径した先細状の係止面部409が形成されている。よって、切削刃本体102Jは、係止面部409の先端側から切削刃本体102Jの駆動軸309が同心状に突出した構成となっている。また、把持本体101Jの係止面部409は、保持具200Jに係止されて、この保持具200Jにて保持した卵30に対する割卵機100Jの位置を位置決め保持するための傾斜面となっている。 Further, on the distal end side of the case body 303 of the grip body 101J, a tapered locking surface portion 409 whose diameter is gradually reduced toward the distal end side is formed. Therefore, the cutting blade body 102J has a configuration in which the drive shaft 309 of the cutting blade body 102J projects concentrically from the tip end side of the locking surface portion 409. In addition, the locking surface portion 409 of the grip body 101J is locked by the holder 200J and serves as an inclined surface for positioning and holding the position of the egg breaking machine 100J with respect to the egg 30 held by the holder 200J. .
 具体的に、保持具200Jは、保持具200Aとほぼ同様の構成であるものの、割卵機100Jを位置決め固定するための位置決め機構500を備えている。位置決め機構500は、保持具200Jの筒状部201Jの一部を上方に突出させた形状の支持片501を有している。この支持片501は、幅方向が面凹弧状に形成された細長矩形状とされており、長手方向を上下方向に沿わせた状態で、この支持片501の下端部を筒状部201Jの上端部に一体的に接続されて取り付けられている。また、支持片501の上端部には、周方向の一部が切り欠かれた略円環状の受け部502が設けられている。この受け部502は、軸方向を上下方向に向けた状態で、この受け部502の周方向の一部が筒状部201Jの上端部に一体的に接続されて取り付けられている。 Specifically, the holder 200J has substantially the same configuration as the holder 200A, but includes a positioning mechanism 500 for positioning and fixing the egg breaking machine 100J. The positioning mechanism 500 has a support piece 501 having a shape in which a part of the cylindrical portion 201J of the holder 200J is protruded upward. The support piece 501 is formed in an elongated rectangular shape in which the width direction is formed in a concave arcuate shape, and the lower end of the support piece 501 is connected to the upper end of the cylindrical portion 201J in a state where the longitudinal direction is vertically aligned. It is connected and attached to the unit. At the upper end of the support piece 501, a substantially annular receiving portion 502 having a part cut off in the circumferential direction is provided. The receiving portion 502 is attached with a part of the receiving portion 502 in the circumferential direction integrally connected to an upper end portion of the cylindrical portion 201J in a state where the axial direction is directed in a vertical direction.
 そして、受け部502には、周方向の一部を軸方向に沿って切り欠いた切欠溝部503が形成されている。切欠溝部503は、割卵機100Jの駆動軸309の径寸法より若干大きな幅寸法に形成されている。そして、受け部502の内周面は、割卵機100Jの係止面部507の傾斜角度に等しい傾斜角度を有する被係止面部504とされている。この被係止面部504は、下端側に向けて徐々に縮径した形状に形成されている。したがって、被係止面部504は、割卵機100Jの先端側である、切削刃本体102J側を下方に向けた状態で、この割卵機100Jの駆動軸309を受け部502の切欠溝部503に挿通させることにより、この割卵機100Jの係止面部507を係止し、図19に示すように、割卵機100Jを位置決め保持する構成となっている。 The receiving portion 502 is formed with a cutout groove portion 503 which is cut out along the axial direction at a part in the circumferential direction. The notch groove portion 503 has a width slightly larger than the diameter of the drive shaft 309 of the egg breaking machine 100J. The inner peripheral surface of the receiving portion 502 is a locked surface portion 504 having a tilt angle equal to the tilt angle of the locking surface portion 507 of the egg breaking machine 100J. The locked surface portion 504 is formed in a shape whose diameter is gradually reduced toward the lower end side. Therefore, the locked surface portion 504 is inserted into the notch groove portion 503 of the receiving portion 502 in a state where the cutting blade body 102J side, which is the tip side of the egg breaking machine 100J, faces downward. By inserting the egg breaking machine 100J, the locking surface 507 of the egg breaking machine 100J is locked, and the egg breaking machine 100J is positioned and held as shown in FIG.
 次に、このように構成された割卵機100Jを用いた容器10の製造方法について説明する。 Next, a method of manufacturing the container 10 using the egg breaking machine 100J configured as described above will be described.
 まず、割卵機100Jの先端側を下方に向けた状態としてから、割卵機100Jの駆動軸309を保持具200Jの切欠溝部503に挿通させて、この割卵機100Jの係止面部409を保持具200Jの被係止面部504に載置させて係止させ位置決め保持させる。次いで、卵30の端部を下方に向けた状態とし、この卵30を保持具200Jの位置決め部203Jの中心位置に挿入していき、この卵30の端部を保持具200Jの窪み207Jに嵌合させ、位置決め部203Jにて卵30の長軸方向を上下方向に向けた状態で位置決め保持させる。 First, after the tip side of the egg breaking machine 100J is directed downward, the drive shaft 309 of the egg breaking machine 100J is inserted into the notch groove 503 of the holder 200J, and the locking surface 409 of the egg breaking machine 100J is moved. It is placed on the locked surface 504 of the holder 200J, locked and positioned and held. Next, the end of the egg 30 is directed downward, and the egg 30 is inserted into the center of the positioning portion 203J of the holder 200J, and the end of the egg 30 is fitted into the recess 207J of the holder 200J. Then, the positioning part 203J positions and holds the egg 30 in a state where the long axis direction of the egg 30 is oriented in the vertical direction.
 この状態で、作業者が割卵機100Jの把持本体101Jのケース体303を把持し、割卵機100Jの昇降スイッチ407を操作して、切削刃本体102Jを下降させていくとともに、割卵機100Jの変速スイッチ408を操作して、切削刃本体102Jを回転駆動させ、この切削刃本体102Jの回転速度を調整する。 In this state, the operator grips the case body 303 of the grip body 101J of the egg breaking machine 100J, operates the lifting switch 407 of the egg breaking machine 100J, lowers the cutting blade body 102J, and moves the egg breaking machine 100J. By operating the speed change switch 408 of 100J, the cutting blade main body 102J is rotationally driven, and the rotation speed of the cutting blade main body 102J is adjusted.
 そして、割卵機100Jの切削刃本体102Jの刃112Jを、卵30の卵殻20の表面に押し付けていくことにより、切削刃本体102Jの刃112Jの回転にて卵30の卵殻20を研削していき、卵30の卵殻20が切断部31にて切削される。その後、割卵機100Jの変速スイッチ408の操作を止め、切削刃本体102Jの回転駆動を停止させるとともに、割卵機100Jの昇降スイッチ407を操作して、切削刃本体102Jを上昇させる。 Then, the blade 112J of the cutting blade body 102J of the egg breaking machine 100J is pressed against the surface of the eggshell 20 of the egg 30 to grind the eggshell 20 of the egg 30 by rotation of the blade 112J of the cutting blade body 102J. The eggshell 20 of the egg 30 is cut at the cutting portion 31. Thereafter, the operation of the speed change switch 408 of the egg breaking machine 100J is stopped, the rotation of the cutting blade body 102J is stopped, and the lifting switch 407 of the egg breaking machine 100J is operated to raise the cutting blade body 102J.
 次いで、切断部31にて切断された卵30の卵殻21、すなわち本体部11を保持具200Jから取り出し、卵30の卵殻20から切削された台座本体13を、切削刃本体102J内から取り出す。この結果、割卵機100Jによる卵30の卵殻20の切削作業により、卵30の卵殻20から本体部11と台座本体13とが形成される。 Next, the eggshell 21 of the egg 30 cut by the cutting unit 31, that is, the main body 11 is taken out from the holder 200J, and the pedestal main body 13 cut from the egg shell 20 of the egg 30 is taken out from the inside of the cutting blade body 102J. As a result, the body 11 and the pedestal body 13 are formed from the eggshell 20 of the egg 30 by the cutting operation of the eggshell 20 of the egg 30 by the egg breaking machine 100J.
 この場合においても、割卵機100Jの切削刃本体102Jを、台座部12の切断部32の径寸法に等しい外径寸法とすることにより、卵殻20や台座本体13を切断部32にて切断でき、台座部12を形成できる。また、切削刃本体102Jの代わりに、エッグアートやイースターエッグ作成用の錐や、泡立て器等をアタッチメントとして取り付けてもよい。 Also in this case, the eggshell 20 and the pedestal main body 13 can be cut by the cutting part 32 by setting the outer diameter of the cutting blade main body 102J of the egg breaking machine 100J to be equal to the diameter of the cutting part 32 of the pedestal part 12. The pedestal portion 12 can be formed. In addition, instead of the cutting blade body 102J, a drill for creating egg art or Easter eggs, a whisk, or the like may be attached as an attachment.

 次に、図20を参照して、さらに他の実施形態の割卵機100Kについて詳細に説明する。なお、以下の説明においても、適宜図1ないし図4を参照する。
(Hole saw breaking machine: integrated type)
Next, an egg breaking machine 100K of still another embodiment will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る割卵機100Kは、図20に示すように、上述した割卵機100Hと同様の、いわゆるホールソー型の構成であるが、切断部31用の切削刃本体102Kと、切断部32用の切削刃本体102Lとを備えた構成となっている。具体的に、割卵機100Kは、把持本体101Kのケース体303内には、このケース体303の基端側から電源104K、吸気機構400K、およびモータ301Kが同心状に収容されて取り付けられている。ケース体303の基端面、すなわち上端面には、電源104Kから吸気機構400Kおよびモータ301Kへの電力の供給をオンオフするスイッチ105Kと、これら吸気機構400Kおよびモータ301Kの駆動を制御するモードスイッチ106と、が取り付けられている。 As shown in FIG. 20, the egg breaking machine 100K according to the present embodiment has a so-called hole saw type configuration similar to the above-described egg breaking machine 100H, but includes a cutting blade body 102K for the cutting portion 31 and a cutting portion 32 cutting blade main body 102L. Specifically, in the egg breaking machine 100K, a power supply 104K, a suction mechanism 400K, and a motor 301K are concentrically housed and mounted in the case body 303 of the grip body 101K from the base end side of the case body 303. I have. A switch 105K for turning on / off the supply of power from the power supply 104K to the intake mechanism 400K and the motor 301K, a mode switch 106 for controlling the driving of the intake mechanism 400K and the motor 301K are provided on the base end face, that is, the upper end face of the case body 303. , Is attached.
 そして、ケース体303の周面には、このケース303体内の空気を排気するための複数の排気口601が設けられている。これら排気口601は、ケース体303内に収容されている吸気機構400Kに連通するように形成されている。したがって、吸気機構400Kは、この吸気機構400Kの駆動により、ケース体303の先端側の開口部から吸い込んだ空気を排気口601からケース体303の外部に排気させる構成となっている。さらに、ケース体303の内部には、このケース体303の先端部よりも切削刃本体102K,102Lの刃112K,112Lが基端側に位置するように、これら切削刃本体102K,102Lの刃112K,112Lよりもケース体303の先端部が先端側に向けて突出した状態とされて切削刃本体102K,102Lが取り付けられている。よって、割卵機100Kにて卵30の卵殻20を割卵する際に、卵30が破卵した場合や、例えば子供等の作業者の指等が不用意にケース体303内に入ってしまう等の危険性を防止できる構成となっている。 複数 Further, a plurality of exhaust ports 601 for exhausting the air inside the case 303 are provided on the peripheral surface of the case 303. These exhaust ports 601 are formed so as to communicate with the intake mechanism 400 </ b> K accommodated in the case body 303. Therefore, the intake mechanism 400K is configured to exhaust the air sucked from the opening on the front end side of the case body 303 to the outside of the case body 303 through the exhaust port 601 by driving the intake mechanism 400K. Further, inside the case body 303, the blades 112K of the cutting blade bodies 102K, 102L are located closer to the base end than the distal end of the case body 303. , 112L, and the cutting blade main bodies 102K, 102L are attached with the front end of the case body 303 protruding toward the front end side. Therefore, when the egg shell 20 of the egg 30 is broken by the egg breaking machine 100K, the egg 30 may break, or a finger of a worker such as a child may enter the case body 303 carelessly. And the like.
 次いで、モータ301Kには、切削刃本体112K,112Lのそれぞれを同時に連動して回転駆動させる回転軸305Kが回転駆動可能に同心状に取り付けられている。この回転軸305Kは、円筒状に形成されており、ケース体303の同心状に取り付けられている。そして、回転軸305Kの内側には、卵30の卵殻20の外表面に負圧状態を形成して真空吸着して位置決め保持する位置決め機構としての吸着機構602が設けられている。この吸着機構602は、管状の吸着管本体603と、この吸着管本体603の先端部に取り付けられた略円筒状の吸着体604とを、備えている。 Next, a rotating shaft 305K that drives the cutting blade main bodies 112K and 112L to rotate simultaneously and simultaneously is concentrically attached to the motor 301K so as to be rotatable. The rotating shaft 305K is formed in a cylindrical shape, and is attached concentrically to the case body 303. Inside the rotation shaft 305K, an adsorption mechanism 602 is provided as a positioning mechanism that forms a negative pressure state on the outer surface of the eggshell 20 of the egg 30, vacuum-adsorbs, and holds the position. The suction mechanism 602 includes a tubular suction tube main body 603 and a substantially cylindrical adsorber 604 attached to a distal end of the suction tube main body 603.
 吸着機構602の吸着管本体603は、回転軸305Kの内径寸法より小さな外径寸法を有しており、この回転軸305Kの内部に同心状に取り付けられている。さらに、吸着管本体603の基端部は、モータ301Kを挿通して吸気機構400Kに固定されており、この吸気機構400Kの駆動により、吸着管本体603の他端部から吸着管本体603内へ外気を吸気して吸気機構400Kを介してケース体303の排気口601から排気する構成となっている。また、吸着管本体603は、回転軸305Kの長さ寸法より大きな長さ寸法を有しており、この吸着管本体603の先端部が回転軸305Kの先端部より先端側に突出した構成となっている。そして、吸着機構602の吸着体604は、弾性変形可能なゴム材等の弾性材にて構成されており、先端側が徐々に拡径したカップ状に形成されている。そして、この吸着体604は、基端側を吸着管本体603の先端側に外嵌合させて同心状に取り付けられている。なお、吸着体604としては、例えばバネ等の、他の弾性材であってもよい。 吸着 The suction tube main body 603 of the suction mechanism 602 has an outer diameter smaller than the inner diameter of the rotating shaft 305K, and is mounted concentrically inside the rotating shaft 305K. Further, the base end of the suction pipe main body 603 is fixed to the suction mechanism 400K through a motor 301K, and the suction mechanism 400K is driven into the suction pipe main body 603 from the other end of the suction pipe main body 603. The configuration is such that outside air is taken in and exhausted from the exhaust port 601 of the case body 303 via the intake mechanism 400K. Further, the suction tube main body 603 has a length larger than the length of the rotating shaft 305K, and the distal end of the suction tube main body 603 protrudes toward the distal end from the distal end of the rotating shaft 305K. ing. The adsorbing body 604 of the adsorbing mechanism 602 is made of an elastic material such as a rubber material that can be elastically deformed, and is formed in a cup shape in which the front end side gradually increases in diameter. The adsorbent 604 is mounted concentrically so that the base end is externally fitted to the distal end of the suction tube main body 603. Note that the adsorbent 604 may be another elastic material such as a spring.
 また、吸着機構602の吸着管本体603の中心には、先端が尖った錐材602Kが切削刃本体102K,102Lに対して同心状に進退可能に取り付けられている。錐材602Kは、切削刃本体102K,102Lにて卵30の卵殻20や台座本体13を切削する際に用いるのではなく、この錐材602Kを卵30の卵殻20等に貫通させて、例えばエッグアート用の素材を形成する際に用いるものである。すなわち、錐材602Kは、モータ301Kの駆動により、錐材602Kの先端部が吸着管本体603内に収容される位置から、この錐材602Kの先端部を卵30の卵殻20の種々の位置に突き刺すことができる位置、例えば切削刃本体102Kの刃112Kよりも先端側に突出する位置までに亘って進退可能な構成となっている。 錐 At the center of the suction tube main body 603 of the suction mechanism 602, a cone member 602K having a sharp tip is attached so as to be able to advance and retreat concentrically with the cutting blade main bodies 102K and 102L. The cone 602K is not used when cutting the eggshell 20 or the pedestal body 13 of the egg 30 with the cutting blade bodies 102K and 102L, but penetrates the cone 602K into the eggshell 20 of the egg 30 and the like, for example, an egg. It is used when forming a material for art. That is, the tip of the cone 602K is moved from the position where the tip of the cone 602K is stored in the suction tube main body 603 to various positions of the eggshell 20 of the egg 30 by driving the motor 301K. It is configured to be able to advance and retreat over a position where it can be pierced, for example, a position where the cutting blade body 102K protrudes forward from the blade 112K.
 一方、回転軸305Kには、卵30の卵殻20を切断部31にて切断するための切削刃本体102Kが同心状に取り付けられている。切削刃本体102Kは、筒状部111Kの基端側が閉塞されて平面状の閉塞部605とされており、この閉塞部605に回転軸305Kが同心状に挿通されて、この回転軸305Kの軸方向における略中間位置に固定されている。また、切削刃本体102Kは、この切削刃本体102Kの刃112Kを、吸着機構602の吸着体604の先端部よりも先端側に突出させた状態で取り付けられている。さらに切削刃本体102Kの刃112Kは、ケース体303の先端部よりも内側に収容されるように取り付けられている。 On the other hand, a cutting blade body 102K for cutting the eggshell 20 of the egg 30 at the cutting section 31 is concentrically attached to the rotating shaft 305K. The cutting blade body 102K has a base portion side of the cylindrical portion 111K closed to form a flat closing portion 605. A rotary shaft 305K is inserted through the closing portion 605 concentrically, and the shaft of the rotary shaft 305K is rotated. It is fixed at a substantially intermediate position in the direction. Further, the cutting blade main body 102K is attached in a state where the blade 112K of the cutting blade main body 102K protrudes to the distal end side from the distal end portion of the suction body 604 of the suction mechanism 602. Further, the blade 112K of the cutting blade main body 102K is attached so as to be housed inside the distal end portion of the case body 303.
 さらに、回転軸305Kには、卵殻20や台座本体13を切断部32にて切断するための切削刃本体102Lが同心状に取り付けられている。切削刃本体102Lの刃面113Lは、切削刃本体102Kの刃面113Kの外径寸法より小さな外径寸法を有している。また、切削刃本体102Lは、筒状部111Lの基端側が閉塞されて平面状の閉塞部606とされ、この閉塞部606に回転軸305Kが同心状に挿通されて、切削刃本体102Kの閉塞部605が固定された位置よりも回転軸305Kの先端側に固定されている。そして、切削刃本体102Lは、この切削刃本体102Lの刃112Lよりも、吸着機構602の吸着体604の先端部が先端側に突出するように構成されている。 Furthermore, a cutting blade body 102L for cutting the eggshell 20 and the pedestal body 13 at the cutting portion 32 is concentrically attached to the rotating shaft 305K. The blade surface 113L of the cutting blade body 102L has an outer diameter smaller than the outer diameter of the blade surface 113K of the cutting blade body 102K. Further, the cutting blade body 102L is closed at the base end side of the cylindrical portion 111L to form a planar closing portion 606, and the rotary shaft 305K is inserted through the closing portion 606 concentrically to close the cutting blade body 102K. The portion 605 is fixed to the distal end side of the rotating shaft 305K from the fixed position. The cutting blade body 102L is configured such that the distal end of the suction body 604 of the suction mechanism 602 protrudes more toward the distal end than the blade 112L of the cutting blade main body 102L.
 回転軸3005Kの基端側には、切削刃本体102K,102Lが受ける圧力を感知するための感圧センサ607が取り付けられている。この感圧センサ607は、略円筒状に形成され回転軸305Kに挿通させた状態でモータ301Kの先端側に取り付けられている。具体的に、感圧センサ607は、切削刃本体102K,102Lが卵30の卵殻20や台座本体13から受ける反力を感知して、これら切削刃本体102K,102Lにて卵30の卵殻20や台座本体13を切削する際における、これら卵殻20または台座本体13のひび割れやつぶれ等の損傷を防止するための圧力感知装置である。さらに、感圧センサ607は、割卵機100Kにて卵30の卵殻20を割卵する際に、卵30が破卵した場合や、例えば子供等の作業者の指等が不用意にケース体303内に入ってしまう等の危険性を防止するものでもある。そして、感圧センサ607には、切削刃本体102K,102Lが卵30の卵殻20や台座本体13から受ける反力が、予め定めた所定の値を超えた場合に、例えばアラーム音を発生させて作業者に認識させる機能を有する制御部609に接続されている。 圧 A pressure-sensitive sensor 607 for detecting the pressure applied to the cutting blade bodies 102K and 102L is attached to the base end side of the rotating shaft 3005K. The pressure-sensitive sensor 607 is formed in a substantially cylindrical shape, and is attached to the distal end side of the motor 301K in a state of being inserted through the rotary shaft 305K. Specifically, the pressure-sensitive sensor 607 senses the reaction force that the cutting blade main bodies 102K and 102L receive from the eggshell 20 and the pedestal main body 13 of the egg 30, and the cutting blade main bodies 102K and 102L detect the egg shell 20 and the egg 30 of the egg 30. This is a pressure sensing device for preventing damage such as cracking or crushing of the eggshell 20 or the pedestal main body 13 when the pedestal main body 13 is cut. Further, when the egg shell 20 of the egg 30 is broken by the egg breaking machine 100K, the pressure-sensitive sensor 607 may be used when the egg 30 breaks or when a finger of a worker such as a child is inadvertently put on the case body. It is also to prevent the danger of entering the inside 303. When the reaction force received by the cutting blade main bodies 102K and 102L from the eggshell 20 of the egg 30 and the pedestal main body 13 exceeds a predetermined value, the pressure-sensitive sensor 607 generates, for example, an alarm sound. It is connected to a control unit 609 having a function of making an operator recognize.
 ここで、モードスイッチ106は、このモードスイッチ106を周方向に回転させることにより、制御部609による制御によって、切削刃本体120Kでの卵30の卵殻20の切削に適した回転速度で切削刃本体120K,120Lを回転させつつ吸気機構400Kを駆動させる大径モードと、切削刃本体120Lでの台座本体13の切削に適した回転速度で切削刃本体120K,120Lを回転させつつ吸気機構400Kを駆動させる小径モードと、錐材602Kを卵30の卵殻20に突き刺す際等に用いる、錐材602Kを進退させる錐モードと、を切り替え可能な構成となっている。 Here, the mode switch 106 rotates the mode switch 106 in the circumferential direction so that the control unit 609 controls the mode switch 106 at a rotational speed suitable for cutting the eggshell 20 of the egg 30 with the cutting blade body 120K. The large diameter mode in which the suction mechanism 400K is driven while rotating the 120K and 120L, and the suction mechanism 400K is driven while rotating the cutting blade bodies 120K and 120L at a rotation speed suitable for cutting the pedestal body 13 by the cutting blade body 120L. It is configured to be able to switch between a small diameter mode in which the cone material 602K is pierced into the eggshell 20 of the egg 30 and a cone mode in which the cone material 602K moves forward and backward.
 さらに、吸気機構400Kの内部には、この吸気機構400Kの下端側の面から吸い込んだ切削片を空気から分離して回収するためのダストボックスとなる集塵装置107が取り外し可能に取り付けられている。この集塵装置107は、略円環状に形成されており、吸気機構400Kの内部に同心状に取り付けられている。また、この集塵装置107は、吸着機構602の吸着体604から吸着管本体603内へ吸い込んだ切削片についても空気から分離して回収できる構成となっている。なお、集塵装置107にて回収した卵30の卵殻20の切削片については、例えば植物の肥料等として用いることができる。 Further, inside the intake mechanism 400K, a dust collection device 107 serving as a dust box for separating and collecting cuttings sucked from the lower surface of the intake mechanism 400K from the air is detachably attached. The dust collecting device 107 is formed in a substantially annular shape, and is mounted concentrically inside the intake mechanism 400K. Further, the dust collecting device 107 is configured such that the cutting pieces sucked into the suction pipe main body 603 from the suction body 604 of the suction mechanism 602 can be separated from the air and collected. The cut pieces of the eggshell 20 of the eggs 30 collected by the dust collecting device 107 can be used as, for example, plant fertilizers.
 また、制御部609は、切削刃本体102K,102Lにて卵30の卵殻20や台座本体13の切削時に受ける圧力を感圧センサ607にて感知している状態から、感圧センサ607が感知する圧力が瞬時に小さくなった場合に、モータ301Kへの電力の供給を停止させ切削刃本体102K,102Lの回転駆動を停止させる自動停止機能を有している。この結果、割卵機100Kによる割卵作業で、卵30が破卵した場合等に生じる、ケース体303を把持している作業者の手等の損傷を防止できる。 Further, the control unit 609 detects the pressure received by the pressure-sensitive sensor 607 when the eggshell 20 of the egg 30 and the pedestal body 13 are cut by the cutting blade main bodies 102K and 102L, and the pressure-sensitive sensor 607 detects the pressure. When the pressure is instantaneously reduced, an automatic stop function is provided for stopping the supply of electric power to the motor 301K and stopping the rotation of the cutting blade main bodies 102K and 102L. As a result, it is possible to prevent the worker's hand holding the case body 303 from being damaged when the egg 30 breaks during the egg breaking operation by the egg breaking machine 100K.
 さらに、制御部609としては、感圧センサ607が感知する圧力に応じて切削刃本体102K,102Lの回転速度を制御してもよい。例えば、切削刃本体102K,102Lにて卵30の卵殻20や台座本体13の切削が進むに連れて回転速度を徐々に高くしていき、これら卵30の卵殻20や台座本体13の切削が完了すると、これら切削刃本体102K,102Lの回転速度を徐々に低くして、その後停止させ、例えば「ぴよぴよ」等の雛のなぎ声を発生させて作業の完了を作業者に伝えるようにする。この結果、割卵機100Kの安全性を高めることができ、作業者が切削刃本体102K,102Lに触れ怪我等することを防止できる。 Furthermore, the control unit 609 may control the rotation speed of the cutting blade main bodies 102K and 102L according to the pressure detected by the pressure-sensitive sensor 607. For example, as the cutting of the eggshell 20 and the pedestal body 13 of the eggs 30 proceeds with the cutting blade bodies 102K and 102L, the rotation speed is gradually increased, and the cutting of the eggshell 20 and the pedestal body 13 of the eggs 30 is completed. Then, the rotational speeds of the cutting blade bodies 102K and 102L are gradually reduced, and then stopped, and a chick whisper such as “Pyo-Pyo” is generated to inform the worker of the completion of the work. As a result, the safety of the egg breaking machine 100K can be enhanced, and the worker can be prevented from touching the cutting blade main bodies 102K and 102L and getting injured.
 なお、この感圧センサ607としては、例えばMEMSを用いた圧力センサなどの、受ける圧力を感知できるセンサであれば種々のセンサを用いることができる。 As the pressure-sensitive sensor 607, various sensors such as a pressure sensor using MEMS can be used as long as the sensor can sense a received pressure.
 さらに、ケース体303の内周面には、各切削刃本体102K,102Lの刃112K,112Lに対する卵30の卵殻20または台座本体13の向きを検出する向き検出装置としての位置センサ608が取り付けられている。この位置センサ608は、ケース体303の内周面のモータ301Kに対向する位置に取り付けられており、ケース体303の内周面に周方向に向けて等間隔に離間した位置に、複数、例えば3個ほど取り付けられている。そして、位置センサ608には、各切削刃本体102K,102Lの刃112K,112Lの中心軸上に、卵殻20または台座本体13の中心軸が位置した場合に、例えばアラーム音を発生させて作業者に認識させる機能を有する制御部609が接続されている。 Further, a position sensor 608 serving as a direction detecting device for detecting the direction of the eggshell 20 or the pedestal body 13 of the egg 30 with respect to the blades 112K and 112L of the respective cutting blade bodies 102K and 102L is attached to the inner peripheral surface of the case body 303. ing. The position sensor 608 is attached to the inner peripheral surface of the case body 303 at a position facing the motor 301K, and a plurality of, for example, About three are attached. When the center axis of the eggshell 20 or the pedestal body 13 is positioned on the center axis of the blades 112K and 112L of the respective cutting blade bodies 102K and 102L, the position sensor 608 generates, for example, an alarm sound and outputs the alarm sound. Is connected to a control unit 609 having a function of causing the control unit 609 to recognize the information.
 このことから、切削刃本体102K,102Lを卵30の卵殻20または台座本体13に押し当てた際における、これら卵30の卵殻20または台座本体13の向きを精度良く合わせることができる。よって、これら卵30の卵殻20または台座本体13を切削する際における位置合わせを容易にできるから、これら卵30の卵殻20または台座本体13を切断部31,32にて切断する作業を精度良く容易にできる。 From this, when the cutting blade bodies 102K and 102L are pressed against the eggshell 20 or the pedestal body 13 of the eggs 30, the orientation of the eggshell 20 or the pedestal body 13 of the eggs 30 can be accurately adjusted. Therefore, since the alignment when cutting the eggshell 20 or the pedestal main body 13 of the eggs 30 can be easily performed, the operation of cutting the eggshell 20 or the pedestal main body 13 of the eggs 30 at the cutting portions 31 and 32 can be easily and accurately performed. Can be.
 なお、この位置センサ608としては、三点測量を行うための赤外線センサ、可視光レーザ、傾斜角センサ、水平儀、レーザダイオード、ジャイロ機構、線形変位センサ、小型な測距センサ、小型なレーザ三角測量式の変位センサ、MEMSを用いた光スイッチなど、卵30の卵殻20や台座本体13の向きを確認できるものであれば、種々のセンサを用いることができる。 The position sensor 608 includes an infrared sensor for performing three-point surveying, a visible light laser, a tilt angle sensor, a horizontal line, a laser diode, a gyro mechanism, a linear displacement sensor, a small distance measuring sensor, and a small laser triangulation. Various sensors can be used as long as they can confirm the orientation of the eggshell 20 of the egg 30 and the pedestal body 13, such as a displacement sensor of the type or an optical switch using MEMS.
 また、制御部609としては、位置センサ608による検出により、切削刃本体102K,102Lに対する卵30の卵殻20の位置が基準位置(中心軸が一致している位置)から一定以上ずれでいる場合に、ブザー音を出し、かつ切削刃本体102K,102Lの回転を停止させることで、卵30の卵殻20に対する切削刃本体102K,102Lの適切な位置への誘導が可能となる。 In addition, the control unit 609 determines that the position of the eggshell 20 of the egg 30 with respect to the cutting blade main bodies 102K and 102L is deviated from the reference position (the position where the central axis coincides) by a certain amount or more by detection by the position sensor 608. By outputting a buzzer sound and stopping the rotation of the cutting blade bodies 102K and 102L, the cutting blade bodies 102K and 102L can be guided to appropriate positions with respect to the eggshell 20 of the egg 30.
 さらに、制御部609は、位置センサ608による検出により、切削刃本体102K,102Lに対する卵30の卵殻20の位置が基準位置から一定の範囲内に位置する場合にのみ、吸気機構402Kを駆動させるとともに、切削刃本体102K,102Lを回転駆動させ、卵30の卵殻20の吸着機構602の吸着体604への吸着を可能とし、切削刃本体102K,102Lによる切削作業を行い得る構成としてもよい。このことから、切削刃本体102K,102Lによる切削時に生じる切削片の極小化のみならず、台座本体13から台座部12を作成する切削刃本体102Lによる切削作業をより精度良く行うことが可能となる。 Furthermore, the control unit 609 drives the air intake mechanism 402K only when the position of the eggshell 20 of the egg 30 with respect to the cutting blade main bodies 102K and 102L is within a certain range from the reference position, based on the detection by the position sensor 608. Alternatively, the cutting blade bodies 102K and 102L may be driven to rotate to enable the suction mechanism 602 of the eggshell 20 of the eggs 30 to be adsorbed to the adsorbing body 604, so that the cutting blade bodies 102K and 102L may perform the cutting operation. From this, it is possible not only to minimize the cut pieces generated during cutting by the cutting blade main bodies 102K and 102L, but also to perform the cutting operation by the cutting blade main body 102L that creates the pedestal portion 12 from the pedestal main body 13 with higher accuracy. .
 また、制御部609は、作業者が把持本体101Hを把持した状態での自然な位置で、割卵機100Hを斜めに向け、この状態で割卵機100Hの切削刃本体102K,102Lを卵30の卵殻20に当てた場合に、位置センサ608による検出により正確な位置を誘導する手振れ補正機能を有していてもよい。 In addition, the control unit 609 turns the egg breaking machine 100H obliquely at a natural position where the worker holds the grip body 101H, and in this state, the cutting blade bodies 102K and 102L of the egg breaking machine 100H are moved to the egg 30. May have a camera shake correction function of inducing an accurate position by detection by the position sensor 608 when the user touches the eggshell 20.
 そして、割卵機100Kの切削刃本体102Lにて台座本体13を切断部32で切り取って開口する際には、保持具200Kが用いられる。この保持具200Kは、台座本体13の基端側の外径寸法、すなわち切断部31の径寸法に等しい外径寸法を有している。また、保持具200Kは、割卵機100Kの軸方向において、ケース体303の先端部と切削刃本体102Lの先端部との間の間隔寸法よりも大きな高さ寸法を有している。さらに、保持具200Kは、台座本体13の外径寸法より小さな内径寸法を有する筒状部201Kと、この筒状部201Kの底部側を閉塞する底面部202Kとで構成された有底円筒状に形成されている。 保持 When the pedestal main body 13 is cut by the cutting portion 32 and opened by the cutting blade main body 102L of the egg breaking machine 100K, the holder 200K is used. The holder 200 </ b> K has an outer diameter on the base end side of the pedestal main body 13, that is, an outer diameter that is equal to the diameter of the cut portion 31. In addition, the holder 200K has a height dimension greater than the distance between the tip of the case body 303 and the tip of the cutting blade body 102L in the axial direction of the egg breaking machine 100K. Further, the holder 200K has a bottomed cylindrical shape composed of a cylindrical portion 201K having an inner diameter smaller than the outer diameter of the pedestal main body 13, and a bottom portion 202K closing the bottom side of the cylindrical portion 201K. Is formed.
 なお、割卵機100Kの構成は、切削刃本体102K,102Lにより、一つの卵30の卵殻20から、本体部11となる卵殻21と、台座部12となる卵殻22のそれぞれを形成できる構成であれば、どのような構成であってもよい。 In addition, the configuration of the egg breaking machine 100K is such that the egg shell 21 serving as the main body 11 and the egg shell 22 serving as the pedestal portion 12 can be formed from the eggshell 20 of one egg 30 by the cutting blade main bodies 102K and 102L. Any configuration may be used.
 次に、このように構成された割卵機100Kを用いた容器10の製造方法について説明する。 Next, a method of manufacturing the container 10 using the egg breaking machine 100K configured as described above will be described.
 まず、割卵機100Kのスイッチ105Kをオンしてモードスイッチ106を大径モードにして吸気機構400Kを駆動させる。すると、回転軸305Kの回転駆動により切削刃本体112K,112Lが連動して回転駆動する。また同時に、吸気機構400Kによる吸気によって、吸着機構602の吸着体604の先端側から吸着管本体603内に空気が吸い込まれていくとともに、ケース体303と切削刃本体112Kとの間の空気が吸い込まれていき、これら吸い込まれた空気がケース体303の排気口601からケース体303の外部に排気される。 First, the switch 105K of the egg breaking machine 100K is turned on, the mode switch 106 is set to the large diameter mode, and the intake mechanism 400K is driven. Then, the cutting blade main bodies 112K and 112L are driven to rotate in conjunction with the rotation of the rotary shaft 305K. At the same time, air is sucked into the suction pipe main body 603 from the tip side of the suction body 604 of the suction mechanism 602 by the suction by the suction mechanism 400K, and the air between the case body 303 and the cutting blade main body 112K is sucked. Then, the sucked air is exhausted to the outside of the case body 303 from the exhaust port 601 of the case body 303.
 この状態で、作業者が割卵機100Kのケース体303を把持し、この割卵機100Kの吸着機構602の吸着体604の中心に卵30の気室側の中心が位置するように、割卵機110Kを卵30に近づけていく。このとき、切削刃本体102K,102Lの刃112K,112Lの中心軸上に卵30の卵殻20の中心軸が位置すると、基準位置と判断されて位置センサ608が作用して、例えばアラーム音が発生し、これら切削刃本体112K,112Lに対する卵30の精度の良い位置合わせが可能となる。 In this state, the operator grips the case body 303 of the egg breaking machine 100K, and moves the egg 30 so that the center of the air chamber side of the egg 30 is located at the center of the suction body 604 of the suction mechanism 602 of the egg breaking machine 100K. The egg machine 110K is moved closer to the egg 30. At this time, when the central axis of the eggshell 20 of the egg 30 is located on the central axis of the blades 112K, 112L of the cutting blade main bodies 102K, 102L, it is determined to be the reference position, and the position sensor 608 operates, for example, to generate an alarm sound. Then, accurate positioning of the egg 30 with respect to the cutting blade main bodies 112K and 112L becomes possible.
 その後、割卵機110Kをさらに卵30に近づけていき、割卵機100Kの吸着機構602の吸着体604を卵30の気室側の中心位置に吸着させる。このとき、吸気機構400Kによる吸気によって、ケース体303と切削刃本体112Kとの間の空気が吸い込まれていき、これら吸い込まれた空気がケース体303の排気口601からケース体303の外部に排気される。 Then, the egg breaking machine 110K is further brought closer to the egg 30, and the adsorbent 604 of the suction mechanism 602 of the egg breaking machine 100K is sucked to the center position of the egg 30 on the air chamber side. At this time, the air between the case body 303 and the cutting blade body 112K is sucked by the suction by the suction mechanism 400K, and the sucked air is exhausted from the exhaust port 601 of the case body 303 to the outside of the case body 303. Is done.
 この後、割卵機100Kの吸着機構602の吸着体604を卵30に押し付けていくと、この吸着機構602の吸着体604が弾性変形して、切削刃本体102Kの刃112Kが卵30の卵殻20の表面に接触する。このとき、吸着機構602の吸着体604の中心に卵30の卵殻20気室側の中心が位置した状態とされて位置決め保持されるため、切削刃本体102Kを卵30の卵殻20に押し当てた際における卵殻20の向きや位置を精度良く合わせできるから、卵30の卵殻20に開口部14を形成する際の位置合わせの最適化や、最適位置以外での誤侵入、すなわち誤った位置での切断を防止できる。したがって、卵30の卵殻20に開口部14を形成する作業を精度良く容易に行うことができる。 Thereafter, when the adsorbing body 604 of the adsorbing mechanism 602 of the egg breaking machine 100K is pressed against the egg 30, the adsorbing body 604 of the adsorbing mechanism 602 is elastically deformed, and the blade 112K of the cutting blade body 102K is moved to the egg shell of the egg 30. Touching the surface of 20. At this time, since the center of the egg shell 20 of the egg 30 on the air chamber side is positioned at the center of the adsorbent 604 of the adsorption mechanism 602 and is positioned and held, the cutting blade body 102K is pressed against the egg shell 20 of the egg 30. Since the orientation and position of the eggshell 20 at the time can be precisely adjusted, optimization of the alignment at the time of forming the opening 14 in the eggshell 20 of the egg 30 and erroneous invasion at a position other than the optimum position, that is, at the wrong position Cutting can be prevented. Therefore, the operation of forming the opening 14 in the eggshell 20 of the egg 30 can be easily and accurately performed.
 さらに、この割卵機100Kを卵30に押し付けていくと、切削刃本体102Kの刃122Kにて卵30の卵殻20の表面が切断部31にて切断される。このとき、この切削刃本体102Kによる卵30の卵殻20の切断時に生じる切削片は、ケース体303と切削刃本体112Kとの間に吸い込まれていき、吸気機構400K内の集塵装置107にて回収される。 Furthermore, when the egg breaking machine 100K is pressed against the egg 30, the surface of the eggshell 20 of the egg 30 is cut by the cutting section 31 with the blade 122K of the cutting blade body 102K. At this time, the cutting pieces generated when the eggshell 20 of the egg 30 is cut by the cutting blade body 102K are sucked between the case body 303 and the cutting blade body 112K, and are collected by the dust collecting device 107 in the suction mechanism 400K. Collected.
 この結果、吸着機構602の吸着体604に台座本体13が吸着された状態となり、卵殻21、すなわち本体部11が形成される。このとき、切削刃本体102Kが卵30の卵殻20から受ける圧力が感圧センサ607にて感知され、この圧力が予め定めた所定の値を超えた場合に、例えばアラーム音が発生し、切削刃本体102Kにて卵30の卵殻20を切削する際における、卵殻20のひび割れやつぶれ等が防止される。 As a result, the pedestal main body 13 is adsorbed to the adsorbent 604 of the adsorption mechanism 602, and the eggshell 21, that is, the main body 11 is formed. At this time, the pressure received by the cutting blade main body 102K from the eggshell 20 of the egg 30 is sensed by the pressure-sensitive sensor 607, and when this pressure exceeds a predetermined value, for example, an alarm sound is generated, and the cutting blade When the eggshell 20 of the egg 30 is cut by the main body 102K, cracks and crushing of the eggshell 20 are prevented.
 そして、本体部11を割卵機100Kから取り除いた後、モードスイッチ106を操作して小径モードとしてから、この割卵機100Kの吸着機構602に吸着されている台座本体13の中心に保持具200Kの中心が位置するように、この割卵機100Kを保持具200Kに近づけていく。このとき、切削刃本体102K,102Lの中心軸上に保持具200Kの中心軸が位置すると位置センサ608が作用して、例えばアラーム音が発生し、これら切削刃本体112K,112Lに対する保持具200Kの精度の良い位置合わせが可能となる。 After the main body 11 is removed from the egg breaking machine 100K, the mode switch 106 is operated to set the small diameter mode, and then the holder 200K is attached to the center of the pedestal body 13 which is sucked by the suction mechanism 602 of the egg breaking machine 100K. The egg breaking machine 100K is moved closer to the holder 200K so that the center of the egg breaking machine is located. At this time, when the central axis of the holder 200K is positioned on the central axis of the cutting blade bodies 102K and 102L, the position sensor 608 operates, for example, an alarm sound is generated, and the holder 200K for the cutting blade bodies 112K and 112L is moved. Accurate positioning can be performed.
 さらに、割卵機100Kの吸着機構602に吸着されている台座本体13を保持具200Kの上面に近づけていくと、吸着機構602の吸着体604がさらに弾性変形して、切削刃本体102Lの刃112Lが台座本体13の表面に接触する。この状態から割卵機100Kを保持具200Kに押し付けていくと、切削刃本体102Lの刃122Lにて台座本体13の表面が切断部32にて切断される。この結果、吸着機構602の吸着体604に卵殻23が吸着された状態となり、卵殻22、すなわち台座部12が形成される。このとき、切削刃本体102Lが台座本体13から受ける圧力が感圧センサ607にて感知され、この圧力が予め定めた所定の値を超えた場合に、例えばアラーム音が発生し、切削刃本体102Lにて台座本体13を切削する際における、台座本体13のひび割れやつぶれ等が防止される。 Further, when the pedestal body 13 sucked by the suction mechanism 602 of the egg breaking machine 100K is brought closer to the upper surface of the holder 200K, the suction body 604 of the suction mechanism 602 is further elastically deformed, and the blade of the cutting blade body 102L is cut. 112 L comes into contact with the surface of the base body 13. When the egg breaking machine 100K is pressed against the holder 200K from this state, the surface of the pedestal body 13 is cut by the cutting portion 32 by the blade 122L of the cutting blade body 102L. As a result, the eggshell 23 is adsorbed to the adsorbent 604 of the adsorption mechanism 602, and the eggshell 22, that is, the pedestal portion 12 is formed. At this time, the pressure received by the cutting blade main body 102L from the pedestal main body 13 is sensed by the pressure-sensitive sensor 607, and when this pressure exceeds a predetermined value, for example, an alarm sound is generated, and the cutting blade main body 102L When the pedestal main body 13 is cut, cracking and crushing of the pedestal main body 13 are prevented.
 この結果、割卵機100Kによる卵30の卵殻20の切削作業により、卵30の卵殻20から本体部11および台座部12が形成される。したがって、外径寸法の異なる刃112K、112Lを有する複数台の割卵機を用いることなく、1台の割卵機100Kのみで、卵30の卵殻20から本体部11および台座部12を製造することができる。 As a result, the main body 11 and the pedestal portion 12 are formed from the eggshell 20 of the egg 30 by the cutting operation of the eggshell 20 of the egg 30 by the egg breaking machine 100K. Therefore, the body portion 11 and the pedestal portion 12 are manufactured from the eggshell 20 of the egg 30 with only one egg breaking machine 100K without using a plurality of egg breaking machines having blades 112K and 112L having different outer diameters. be able to.
 さらに、割卵機100Kにて卵30の卵殻20の一部に小さな穴をあけてエッグアートの素材を形成する場合には、割卵機100Kのスイッチ105Kをオンしてモードスイッチ106を錐モードにする。すると、モータ301Kの駆動により、吸着管本体603内に収容された位置から切削刃本体102Kの刃112Kよりも先端側に突出する位置まで錐材602Kが進出していく。この状態で、錐材602Kを卵30の卵殻20の気室側の中心位置等に貫通させることにより、この卵30の卵殻20に小さな穴を空けることができる。そして、この小さな穴から卵殻20内の卵液を取り出すことにより、この卵殻20をエッグアート用の素材として用いることができる。 Further, when a small hole is made in a part of the eggshell 20 of the egg 30 with the egg breaking machine 100K to form a material for the egg art, the switch 105K of the egg breaking machine 100K is turned on and the mode switch 106 is set to the cone mode. To Then, the driving of the motor 301K causes the cone member 602K to advance from the position accommodated in the suction tube main body 603 to a position protruding more distally than the blade 112K of the cutting blade main body 102K. In this state, a small hole can be made in the egg shell 20 of the egg 30 by penetrating the cone material 602K into the center position on the air chamber side of the egg shell 20 of the egg 30. Then, by taking out the egg fluid in the eggshell 20 from the small hole, the eggshell 20 can be used as a material for egg art.
 その後、割卵機100Kのスイッチ105Kをオフする。すると、モータ301Kの駆動により、切削刃本体102Kの刃112Kよりも先端側に突出した位置から吸着管本体603内に収容される位置へ錐材602Kが後退していき、この吸着管本体603内に錐材602Kが収容される。したがって、錐材602Kを使用するとき以外は、吸着管本体603内に錐材602Kが収容されるため、この錐材602Kが突出していることに伴う、作業者の損傷等を防止することができる。 Then, switch 105K of egg breaking machine 100K is turned off. Then, the driving of the motor 301K causes the cone member 602K to retreat from a position protruding more distally than the blade 112K of the cutting blade main body 102K to a position accommodated in the suction pipe main body 603. The pyramid material 602K is accommodated therein. Therefore, except when the conical member 602K is used, the conical member 602K is accommodated in the suction pipe main body 603, and thus, it is possible to prevent the worker from being damaged due to the protruding conical member 602K. .
 なお、割卵機100Kにおいては、切削刃本体102K,102Lの中心に対する卵30の卵殻20の中心を位置決めする位置決め機構として吸着機構602を用いているが、図21に示すさらに他の実施形態のように、細長いコアドリル602Mを切削刃本体102Mの中心に同心状に取り付けて、位置決め機構として用いることもできる。この場合は、コアドリル602Mを卵30の卵殻20の中心位置に貫通させることにより、切削刃本体102Mの中心に対する卵30の卵殻20の中心を位置決めできる。 In addition, in the egg breaking machine 100K, the suction mechanism 602 is used as a positioning mechanism for positioning the center of the eggshell 20 of the egg 30 with respect to the centers of the cutting blade main bodies 102K and 102L, but in still another embodiment shown in FIG. As described above, the elongated core drill 602M can be attached concentrically to the center of the cutting blade body 102M and used as a positioning mechanism. In this case, the center of the eggshell 20 of the egg 30 with respect to the center of the cutting blade body 102M can be positioned by penetrating the core drill 602M into the center of the eggshell 20 of the egg 30.
 また、図22に示すさらに他の実施形態のように、先端が尖った錐材602Nのみを切削刃本体102Nの中心に同心状に取り付けて、位置決め機構として用いることもできる。この場合においても、切削刃本体102Nにて卵30の卵殻20を切削する前に、錐材602Nを卵30の卵殻20の中心位置に貫通させることにより、切削刃本体102Nの中心に対する卵30の卵殻20の中心を位置決めできる。なお、位置決め機構としては、円盤状の弾性を有するシート体の中心位置に放射線状の複数の切れ込みが入った構成としてもよい。 Also, as in still another embodiment shown in FIG. 22, only a cone member 602N having a sharp tip may be concentrically attached to the center of the cutting blade body 102N and used as a positioning mechanism. Also in this case, before cutting the eggshell 20 of the egg 30 with the cutting blade body 102N, the cone member 602N is made to penetrate the center position of the eggshell 20 of the egg 30 so that the eggs 30 with respect to the center of the cutting blade body 102N. The center of the eggshell 20 can be positioned. Note that the positioning mechanism may have a configuration in which a plurality of radial cuts are formed at the center position of the disk-shaped sheet body having elasticity.
 さらに、割卵機100Kでは、吸気機構400による吸気によって、切削刃本体102Kでの卵30の卵殻20の切断時に生じる切削片を、ケース体303と切削刃本体112Kとの間へ吸い込んでケース体303の排気口601から外部へ排出させる構成としている。ただし、この構成に限らず、図23に示すさらに他の実施形態のように、切削刃本体102Pの内側に、この切削刃本体102Pの内面に沿った吸気用壁面部701を設け、この切削刃本体102Pでの卵30の卵殻20の切断時に生じる切削片を、切削刃本体102Pと吸気用壁面部701との間へ吸い込んで排出させる構成にしても良い。 Further, in the egg breaking machine 100K, the cut pieces generated when the eggshell 20 of the egg 30 is cut by the cutting blade body 102K are sucked into the space between the case body 303 and the cutting blade body 112K by the suction by the suction mechanism 400 to suck the cut body. It is configured to be exhausted to the outside from the exhaust port 601 of 303. However, the present invention is not limited to this configuration. As in still another embodiment shown in FIG. 23, an intake wall portion 701 is provided inside the cutting blade body 102P along the inner surface of the cutting blade body 102P, A configuration may be adopted in which a cutting piece generated when the eggshell 20 of the egg 30 is cut by the main body 102P is sucked and discharged between the cutting blade main body 102P and the intake wall portion 701.
 この場合、吸気用壁面部701は、切削刃本体102Pの筒状部111Pより外径寸法が小さな円筒状の内周面部702と、この内周面部702の基端側を閉塞する平板状の閉塞面部703と、この閉塞面部703の中心位置に開口した循環口704と、この循環口704に連通して基端側に突出した円筒状の循環路705とで構成されている。そして、吸気用壁面部701の内周面部702は、この内周面部702の先端部を切削刃本体102Pの先端部よりも基端側にずらした位置として、切削刃本体102Pの内部の中心位置に同心状に設置されている。閉塞面部703は、切削刃本体102Pの閉塞部605Pとの間に所定の空間ができるように、この切削刃本体102Pの閉塞部605Pから所定の間隔を先端側に離した位置に、この閉塞部605Pの中心位置に同心状に取り付けられている。循環路705は、切削刃本体102Pの回転軸305Pの内部に挿通されており、この回転軸305Pの内部に同心状に取り付けられている。 In this case, the intake wall portion 701 has a cylindrical inner peripheral surface portion 702 having an outer diameter smaller than the cylindrical portion 111P of the cutting blade main body 102P, and a flat plate-shaped closure that closes the base end side of the inner peripheral surface portion 702. It comprises a surface portion 703, a circulation port 704 opened at the center of the closed surface portion 703, and a cylindrical circulation path 705 communicating with the circulation port 704 and protruding toward the base end. The inner peripheral surface portion 702 of the intake wall surface portion 701 is positioned at a position where the distal end of the inner peripheral surface portion 702 is shifted to the proximal end side from the distal end portion of the cutting blade main body 102P. Are installed concentrically. The closing surface portion 703 is located at a position separated from the closing portion 605P of the cutting blade body 102P by a predetermined distance toward the distal end so that a predetermined space is formed between the closing surface portion 703 and the closing portion 605P of the cutting blade body 102P. It is mounted concentrically at the center of 605P. The circulation path 705 is inserted through the inside of the rotating shaft 305P of the cutting blade main body 102P, and is mounted concentrically inside the rotating shaft 305P.
 そして、切削刃本体102Pは、吸着機構602Pの吸着管本体603Pと吸気用壁面部701の循環路705との間から吸気用壁面部701の内部へ外気が吸気される構成とされている。したがって、図23に示すように、切削刃本体102Pの吸着機構602Pの吸着体604Pを卵30の卵殻20に吸着させ、切削刃本体102Pの刃112Pを卵30の卵殻20に押し当てて切削する際には、吸気用壁面部701の内部へ吸気された空気が、吸気用壁面部701の内周面部702の先端部と卵30の卵殻20の表面との間の隙間が集塵口となり、この集塵口から切削刃本体102Pの筒状部111Pと吸気用壁面部701の内周面部702との間の空間へ吸い込まれていく。そして、切削刃本体102Pの閉塞部605Pと吸気用壁面部701の閉塞面部703との間の空間を介して、切削刃本体102Pの回転軸305Pと吸気用壁面部701の循環路705との間の空間から外部へ排気されていく。 切削 The cutting blade body 102P is configured so that outside air is sucked into the inside of the suction wall 701 from between the suction pipe main body 603P of the suction mechanism 602P and the circulation path 705 of the suction wall 701. Therefore, as shown in FIG. 23, the adsorbent 604P of the adsorption mechanism 602P of the cutting blade body 102P is adsorbed on the eggshell 20 of the egg 30, and the blade 112P of the cutting blade body 102P is pressed against the eggshell 20 of the egg 30 to perform cutting. In this case, the air sucked into the intake wall 701 has a gap between the tip of the inner peripheral surface 702 of the intake wall 701 and the surface of the eggshell 20 of the egg 30 serving as a dust collection port. The dust is drawn into the space between the cylindrical portion 111P of the cutting blade body 102P and the inner peripheral surface 702 of the intake wall 701 from the dust collection port. Then, between the rotating shaft 305P of the cutting blade body 102P and the circulation path 705 of the suction wall portion 701, via a space between the closing portion 605P of the cutting blade body 102P and the closing surface portion 703 of the suction wall portion 701. It is exhausted from the space outside.
 したがって、切削刃本体102Pにて卵30の卵殻20を切削する際に生じる切削片を、切削刃本体102Pの内部から外部へ排出でき、切削時に生じる切削片の切断部31から卵殻20の内部への侵入を効率良く防止できる。よって、卵殻20内の卵黄および卵白への切削片の混入を防止できるから、これら卵黄および卵白の利用が容易になる。 Therefore, a cutting piece generated when the eggshell 20 of the egg 30 is cut by the cutting blade body 102P can be discharged from the inside of the cutting blade body 102P to the outside, and from the cutting portion 31 of the cutting piece generated during cutting into the eggshell 20. Can be efficiently prevented. Therefore, the mixing of the cut pieces into the yolk and the albumen in the eggshell 20 can be prevented, so that the use of the albumen and the albumen becomes easy.
 なお、切削刃本体102Pの先端部に対する、吸気用壁面部701の内周面部702の先端部との位置をより先端側にずらすことによって、これら切削刃本体102Pと内周面部702との間への吸込み角度を鋭角にでき吸気圧を高くできる。一方、切削刃本体102Pの先端部に対する、吸気用壁面部701の内周面部702の先端部との位置をより基端側にずらすことによって、切削刃本体102Pと内周面部702との間への吸込み角度を鈍角にでき吸気圧を低くできる。 Note that, by shifting the position of the tip of the inner peripheral surface 702 of the suction wall portion 701 with respect to the tip of the cutting blade main body 102P more distally, the position between the cutting blade main body 102P and the inner peripheral surface 702 is shifted. The intake angle can be made acute and the intake pressure can be increased. On the other hand, by shifting the position of the distal end portion of the inner peripheral surface portion 702 of the suction wall portion 701 with respect to the distal end portion of the cutting blade main body 102P more proximally, the position between the cutting blade main body 102P and the inner peripheral surface portion 702 is shifted. The intake angle can be made obtuse and the intake pressure can be reduced.

 次に、図24を参照して、さらに他の実施形態の割卵機100Qについて詳細に説明する。なお、以下の説明においても、適宜図1ないし図4を参照する。
(Hole saw egg breaking machine: industrial use)
Next, with reference to FIG. 24, an egg breaking machine 100Q of still another embodiment will be described in detail. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る割卵機100Qは、基本的には上述した割卵機100Gと同様の構成であるが、いわゆるホールソー型の切削刃本体102Qを複数、例えば計8本を備えた構成となっている。具体的に、割卵機100Qは、複数、例えば計8本の切削刃本体102Qを有する切削刃群140Qと、この切削刃群140のすべての切削刃本体102Qを同時に連動して回転駆動させる駆動機構801とを備えている。切削刃群140Qは、矩形平板状の支持板141Qを有し、この支持板141Qの下面に各切削刃本体102Qの刃112Qを下方に向けた状態として等間隔に格子状に並べて取り付けられている。 The egg breaking machine 100Q according to the present embodiment has basically the same configuration as the above-described egg breaking machine 100G, but has a configuration including a plurality of so-called hole saw type cutting blade bodies 102Q, for example, a total of eight. ing. Specifically, the egg breaking machine 100Q is configured to drive a plurality of, for example, eight cutting blade bodies 102Q having a total of eight cutting blade bodies 102Q, and to simultaneously rotate and drive all the cutting blade bodies 102Q of the cutting blade group 140 simultaneously. And a mechanism 801. The cutting blade group 140Q has a rectangular flat plate-like support plate 141Q, and is attached to the lower surface of the support plate 141Q in a grid pattern at equal intervals with the blades 112Q of each cutting blade body 102Q facing downward. .
 また、切削刃群140Qの各切削刃本体102Qは、切断部31の径寸法に等しい外径寸法を有している。そして、切削刃群140Qの支持板141Q上に駆動機構801が取り付けられている。駆動機構801は、各切削刃本体102Qを回転駆動させるための駆動装置となるモータ802を備えている。さらに、支持板141Qは、一対のフレーム142Q間に昇降可能に取り付けられている。このフレーム142Qには、切削刃群140を昇降駆動させるモータ143Qと、モータ143Q,802に電力を供給する電源104Qと、が取り付けられている。 各 Further, each cutting blade main body 102Q of the cutting blade group 140Q has an outer diameter equal to the diameter of the cutting portion 31. The drive mechanism 801 is mounted on the support plate 141Q of the cutting blade group 140Q. The drive mechanism 801 includes a motor 802 that serves as a drive device for rotationally driving each cutting blade body 102Q. Further, the support plate 141Q is attached between the pair of frames 142Q so as to be able to move up and down. A motor 143Q that drives the cutting blade group 140 up and down, and a power supply 104Q that supplies electric power to the motors 143Q and 802 are attached to the frame 142Q.
 また、切削刃群140Qの支持板141Qの下面に対応する位置には、複数、例えば計8個の卵30を位置決め保持する保持具200Qが設置されている。この保持具200Qは、支持板141Qとほぼ同じ大きさの保持板145Qを備え、この保持板145Qの上面に卵30が等間隔に格子状に位置決め保持される構成となっている。すなわち、保持具200Qは、保持した各卵30の中心に、各切削刃本体102Qの刃112Qが接触し、これら各切削刃本体102Qの刃112Qの中心に対向する位置に、各卵30の長軸方向を上下方向に沿わせた状態として保持する構成とされている。 保持 A holder 200Q that positions and holds a plurality of, for example, eight eggs 30 in total is provided at a position corresponding to the lower surface of the support plate 141Q of the cutting blade group 140Q. The holder 200Q includes a holding plate 145Q having substantially the same size as the support plate 141Q, and the eggs 30 are positioned and held on the upper surface of the holding plate 145Q at regular intervals in a lattice shape. That is, the holder 200Q is such that the blade 112Q of each cutting blade body 102Q contacts the center of each egg 30 held, and the length of each egg 30 is set at a position facing the center of the blade 112Q of each cutting blade body 102Q. It is configured to hold the state in which the axial direction is along the vertical direction.
 したがって、保持具200Qの保持板145Q上に、卵殻20の長軸方向を上下方向に沿わせた状態で計8個の卵30を並べて保持させる。そして、電源104Qからモータ802に電力を供給して各切削刃本体102Qのそれぞれを回転駆動させる。この状態で、電源104Qからモータ143Qに電力を供給して支持板141Qを降下させていくことにより、各切削刃本体102Qの刃112Qが各卵30の卵殻20の表面に接触し、これら各切削刃本体102Qの回転駆動により各卵30の卵殻20を切断部31にて切断できる。よって、割卵機100Qによる卵30の卵殻20の切削作業により、複数、例えば8個の本体部11および台座本体13を同時に形成できる。このことから、複数の卵30の卵殻20の開口作業を容易に行うことができ、複数の卵30の卵殻20に開口部14を形成するための割卵機100Qの使い勝手を向上することができる。 Therefore, a total of eight eggs 30 are arranged and held on the holding plate 145Q of the holding tool 200Q with the long axis direction of the eggshell 20 along the vertical direction. Then, electric power is supplied from the power supply 104Q to the motor 802 to rotate each of the cutting blade bodies 102Q. In this state, by supplying power from the power source 104Q to the motor 143Q to lower the support plate 141Q, the blade 112Q of each cutting blade body 102Q comes into contact with the surface of the eggshell 20 of each egg 30, and these cutting The eggshell 20 of each egg 30 can be cut at the cutting section 31 by the rotational drive of the blade body 102Q. Accordingly, a plurality of, for example, eight main bodies 11 and the pedestal main bodies 13 can be simultaneously formed by the cutting operation of the eggshell 20 of the eggs 30 by the egg breaking machine 100Q. From this, the opening operation of the eggshell 20 of the plurality of eggs 30 can be easily performed, and the usability of the egg breaking machine 100Q for forming the opening 14 in the eggshell 20 of the plurality of eggs 30 can be improved. .
 なお、本割卵機100Qの切削刃本体102Qを、切断部32の径寸法に等しい外径寸法にすることにより、同時に複数の卵殻20または台座本体13を切断部32にて切断する構成にすることもできる。 The cutting blade main body 102Q of the egg breaking machine 100Q has an outer diameter equal to the diameter of the cutting portion 32, so that the plurality of eggshells 20 or the pedestal main body 13 can be cut at the cutting portion 32 at the same time. You can also.
[乾燥用治具]
 次に、図25および図26(A)を参照して、本発明の実施形態に係る容器10の製造工程に用いる乾燥用治具900について詳細に説明する。なお、以下の説明においても、適宜図1ないし図4を参照する。
[Jig for drying]
Next, the drying jig 900 used in the manufacturing process of the container 10 according to the embodiment of the present invention will be described in detail with reference to FIGS. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る乾燥用治具900は、複数、例えば計12個の本体部11となる卵殻21を乾燥させるための乾燥用トレイであり、主として、これら卵殻21の外表面21a等に塗布されたコーティング剤を自然乾燥させるために用いられる。具体的に、乾燥用治具900は、矩形平板状のプレート901を備えている。プレート901には、複数、例えば計12本の細長円柱状である棒状の支柱902が垂直に取り付けられている。これら支柱902は、これら支柱902の軸方向を鉛直方向に沿わせた状態とし、これら支柱902の一端部である下端部を、プレート901上に挿入させる等して固定されている。 The drying jig 900 according to the present embodiment is a drying tray for drying a plurality of, for example, a total of 12 eggshells 21 to be the main body 11, and is mainly applied to the outer surface 21a of the eggshell 21 and the like. It is used to air-dry the coating agent. Specifically, the drying jig 900 includes a rectangular plate 901. On the plate 901, a plurality of, for example, a total of twelve elongated columnar rod-shaped columns 902 are vertically mounted. These pillars 902 are fixed in such a manner that the axial direction of the pillars 902 is aligned with the vertical direction, and the lower ends, which are one ends of the pillars 902, are inserted into the plate 901.
 また、これら支柱902は、プレート901上に等間隔に格子状に並べて配置されており、これら各支柱902は、図25に示すように、これら各支柱902の上端側に、卵殻21の開口部14から、これら卵殻21内へ各支柱902の先端部を挿入させて、これら各支柱902に卵殻21を係止させた状態で、これら各卵殻21の外表面21a同士が接触、すなわち擦れ合わない、例えば25mm~30mm程度の間隔を空けて取り付けられている。すなわち、これら支柱902は、卵30の長軸方向に直交する径方向における最大径寸法の2倍程度の間隔を空けて取り付けられている。 These columns 902 are arranged in a grid pattern at equal intervals on the plate 901. As shown in FIG. 25, each column 902 has an opening of the eggshell 21 at the upper end side of each column 902. 14, the outer surfaces 21a of the eggshells 21 do not contact with each other, that is, do not rub against each other in a state where the tips of the struts 902 are inserted into the eggshells 21 and the eggshells 21 are locked to the struts 902. For example, they are attached at intervals of about 25 mm to 30 mm. That is, the struts 902 are attached at intervals of about twice the maximum diameter in the radial direction orthogonal to the long axis direction of the egg 30.
 さらに、これら支柱902の先端部には、これら支柱902に係止された卵殻21の割れやひびの発生、すなわち損傷を防止するための緩衝部材903がそれぞれ取り外し可能に取り付けられている。これら緩衝部材903は、例えばスポンジやゴム等の弾性を有する素材にて、例えば直径15mm程度の半球状に形成されている。また、これら緩衝部材903は、卵殻21の開口部14の径寸法より小さく、かつ卵殻22の開口部15の径寸法より大きな外径寸法に形成されている。そして、これら緩衝部材903は、平面部904側を下方に向けた状態とし、この平面部904側の中心位置に支柱902の上端部が挿入される等して、これら支柱902の上端部に同心状に固定されている。これら緩衝部材903の球面部905は、支柱902にて卵殻21を係止している状態で、これら支柱902の上端部を回転中心とする、各卵殻21の回転や揺れを防止する形状、すなわち、卵殻21の端部側の内表面21bの形状に略等しい形状の球面状に形成されている。 緩衝 Furthermore, cushioning members 903 for preventing cracks and cracks of the eggshells 21 locked to the pillars 902, that is, damages are prevented from being attached to the tips of the pillars 902, respectively. These buffer members 903 are formed of a material having elasticity such as sponge or rubber, for example, and formed in a hemispherical shape with a diameter of about 15 mm. Further, these buffer members 903 are formed to have an outer diameter smaller than the diameter of the opening 14 of the eggshell 21 and larger than the diameter of the opening 15 of the eggshell 22. The cushioning members 903 are concentric with the upper ends of the struts 902 by, for example, inserting the upper ends of the struts 902 into the center positions of the flat portions 904 with the flat portions 904 facing downward. It is fixed in the shape. The spherical portions 905 of the cushioning members 903 have a shape that prevents the eggshells 21 from rotating and swinging around the upper end of the columns 902 while the eggshell 21 is locked by the columns 902, that is, The egg shell 21 is formed into a spherical shape having a shape substantially equal to the shape of the inner surface 21b on the end side.
 したがって、本体部11となる卵殻21の外表面21a等に塗布されたコーディング剤を自然乾燥させる際には、まず、各卵殻21の開口部14を下方に向けた状態とする。その後、これら各卵殻21の開口部14に乾燥用治具900の支柱902の上端部を挿入させるようにして、これら各卵殻21の内表面21bのうちの開口部14に対向する部分に、緩衝部材903の球面部905を同心状に位置させて載置させる。この状態で、予め定めた所定の時間に亘って自然放置することによって、乾燥用治具900にて保持されている各卵殻21の外表面21a等に塗布されているコーティング剤を自然乾燥させることができる。 Therefore, when the coating agent applied to the outer surface 21a of the eggshell 21 to be the main body 11 is naturally dried, first, the openings 14 of the eggshells 21 are directed downward. Thereafter, the upper end of the support 902 of the drying jig 900 is inserted into the opening 14 of each of the eggshells 21, and the portion of the inner surface 21 b of each of the eggshells 21 facing the opening 14 is buffered. The spherical portion 905 of the member 903 is concentrically positioned and placed. In this state, the coating agent applied to the outer surface 21a and the like of each eggshell 21 held by the drying jig 900 is naturally dried by being left naturally for a predetermined time. Can be.
 この自然乾燥の際に、何等かの衝撃や風等の影響により、各支柱902にて保持されている卵殻21が各支柱902の先端部を中心として回転したり揺れてしまった場合であっても、卵殻21の外表面21a同士が接触しない程度の間隔を空けて各支柱902が取り付けられているため、これら卵殻21の外表面21a同士が接触しない。したがって、これら卵殻21の外表面21a同士が接触することで生じ得る、これら卵殻21の割れや欠け等の破損を適切に防止できる。同時に、これら卵殻21の外表面21aに塗布されたコーティング剤同士が接触することで生じ得る、コーティング剤の剥がれや表面の波打ち等を防止できる。よって、これら卵殻21の外表面21aに塗布されたコーティング剤を均一な厚さでなめらかな表面のまま乾燥させることができるから、このコーティング剤の適切な乾燥処理を容易に行うことができる。 At the time of the natural drying, the eggshell 21 held by each of the columns 902 is rotated or shaken around the tip of each of the columns 902 due to some impact or wind. Also, since the columns 902 are attached with an interval such that the outer surfaces 21a of the eggshell 21 do not contact each other, the outer surfaces 21a of the eggshell 21 do not contact each other. Therefore, breakage such as cracking or chipping of the eggshell 21 that can occur when the outer surfaces 21a of the eggshell 21 come into contact with each other can be appropriately prevented. At the same time, it is possible to prevent the coating agent applied on the outer surface 21a of the eggshell 21 from coming into contact with each other, thereby preventing the coating agent from peeling off or waving on the surface. Therefore, since the coating agent applied to the outer surface 21a of the eggshell 21 can be dried with a uniform thickness and a smooth surface, an appropriate drying treatment of the coating agent can be easily performed.
 さらに、台座部12となる卵殻22の開口部15を上方に向けた状態とし、この状態で、卵殻22の切断部31側に乾燥用治具900の支柱902の上端部を挿入させるようにすることによって、これら各卵殻22の開口部14に対して同心状となるように、これら各卵殻22の内表面22bに緩衝部材903の球面部905を対向させて位置させて載置させることができる。したがって、この状態で、予め定めた所定の時間に亘って自然放置することにより、乾燥用治具900にて保持されている各卵殻22の外表面22a等に塗布されているコーティング剤を適切に自然乾燥させることができる。したがって、台座部12であっても、台座部12となる卵殻22の外表面22a等に塗布されているコーティング剤の適切な乾燥処理を容易に行うことができる。 Further, the opening 15 of the eggshell 22 serving as the pedestal portion 12 is oriented upward, and in this state, the upper end of the support 902 of the drying jig 900 is inserted into the cut portion 31 of the eggshell 22. Thus, the spherical portion 905 of the buffer member 903 can be placed and placed on the inner surface 22b of each of the eggshells 22 so as to be concentric with the opening 14 of each of the eggshells 22. . Therefore, in this state, the coating agent applied to the outer surface 22a and the like of each eggshell 22 held by the drying jig 900 is appropriately left by being left naturally for a predetermined time. Allow to air dry. Therefore, even in the case of the pedestal portion 12, appropriate drying treatment of the coating agent applied to the outer surface 22a of the eggshell 22 to be the pedestal portion 12 can be easily performed.
 なお、図25および図26(A)に示す乾燥用治具900では、緩衝部材903の形状を半球状としているが、例えば図26(B)に示す緩衝部材903Rのように平面視正方形の平板状としてもよい。すなわち、緩衝部材903,903Rの形状は、本体部11や台座部12を適切に自然乾燥できる形状であれば、例えば、図27(A)に示すような使用時に開くことができる傘のような形状の緩衝部材903Sや、図27(B)に示すような先端側に向けて徐々に縮径したコイル状の緩衝部材903T、図27(C)に示すような支柱の先端部から複数、例えば3本の係止片906Aが等間隔に斜め上方に突出した形状の緩衝部材903Uなど、どのような形状であってもよい。そして、この緩衝部材903Uにおいては、これら3本の係止片を連結する平面視三角形状の連結片906Bが設けられている。この連結片906Bは水平な直線状に設けられており、計3本の係止片906Aのそれぞれを水平位置で連結している。また、乾燥用治具900を、例えばスチームコンベクションオーブンレンジ等の加熱装置に入れて、乾燥用治具900にて保持した卵殻21,22を加熱乾燥させることもできる。 In the drying jig 900 shown in FIGS. 25 and 26A, the shape of the buffer member 903 is hemispherical. However, for example, a flat plate having a square shape in plan view like a buffer member 903R shown in FIG. It is good also as a shape. That is, as long as the shape of the buffer members 903 and 903R is such that the main body portion 11 and the pedestal portion 12 can be appropriately and naturally dried, for example, like an umbrella that can be opened at the time of use as shown in FIG. A buffer member 903S having a shape, a coil-shaped buffer member 903T whose diameter is gradually reduced toward the distal end side as shown in FIG. 27B, and a plurality of, for example, from a distal end portion of a column as shown in FIG. Any shape, such as a cushioning member 903U in which three locking pieces 906A project obliquely upward at equal intervals, may be used. And, in the cushioning member 903U, a connecting piece 906B having a triangular shape in plan view is provided for connecting these three locking pieces. The connecting piece 906B is provided in a horizontal straight line, and connects each of the three locking pieces 906A in a horizontal position. Alternatively, the drying jig 900 may be placed in a heating device such as a steam convection microwave oven, and the eggshells 21 and 22 held by the drying jig 900 may be heated and dried.
 次に、図28を参照して、さらに他の乾燥用治具900Vについて詳細に説明する。なお、以下の説明においても、適宜図1ないし図4を参照する。 Next, another drying jig 900V will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
 本実施形態に係る乾燥用治具900Vは、基本的には上述した乾燥用治具900と同様の構成であるが、本体部11となる卵殻21を乾燥させるための各支柱902の間に、台座部12となる卵殻22を乾燥させるための支柱907が等間隔に格子状に設けられている。そして、これら各支柱907の先端部には、二股に分れた係止片部908が設けられ、これら各係止片部908のいずれか一方の先端部を卵殻22の切断部31側から挿入して、この卵殻22の内表面22bを係止させて、この卵殻22を乾燥できる構成となっている。 The drying jig 900V according to the present embodiment has basically the same configuration as the above-described drying jig 900, but between the respective columns 902 for drying the eggshell 21 that becomes the main body portion 11. Pillars 907 for drying the eggshell 22 to be the pedestal portion 12 are provided in a grid at equal intervals. At the distal end of each of the columns 907, a locking piece 908 divided into two branches is provided, and one of the distal ends of each of the locking pieces 908 is inserted from the cut portion 31 side of the eggshell 22. Then, the inner surface 22b of the eggshell 22 is locked so that the eggshell 22 can be dried.
 すなわち、各支柱902は、支柱907より長く形成されており、これら支柱907の係止片部908のいずれか一方に卵殻22を係止させた状態であっても、各支柱902の緩衝部材903にて保持している各卵殻21が、これら各卵殻22に接触しない程度の長さ寸法に形成されている。さらに、各支柱907の係止片部908の間には、これら係止片部908に卵殻22を係止させた際の、この卵殻22の支柱907への接触を防止して、この卵殻の損傷を防止する連結片部909が取り付けられている。 That is, each support 902 is formed to be longer than the support 907, and even when the eggshell 22 is locked to one of the locking pieces 908 of the support 907, the cushioning member 903 of each support 902 is provided. Each of the eggshells 21 held at the position is formed to have such a length that it does not contact the eggshells 22. Further, between the locking pieces 908 of the columns 907, when the eggshell 22 is locked to the locking pieces 908, contact of the eggshell 22 with the columns 907 is prevented, and A connecting piece 909 for preventing damage is attached.
 この連結片部909は、中心部が上方に突出した側面視逆Vの字状に形成されており、この連結片部909の両端部が各係止片部908の長さ方向の略中心位置に接続されて取り付けられている。そして、連結片部909は、係止片部908のいずれか一方の先端部を卵殻22の切断部31側から挿入し、この卵殻22の内表面22bを係止させた際に、この卵殻22の内表面22bに連結片部909の屈曲した頂点部909Aが接触して係止し、この頂点部909Aと係止片部908との2点の係止により、仮に卵殻22が揺れたとしても支柱907に接触したり引っ掛かったりしないように卵殻22を係止する構成となっている。なお、連結片部909は、仮に卵殻22が揺れたとしても支柱907に接触したり引っ掛かったりしない形状であれば、例えば上方に突出する円弧状などといった、どのような形状であっても良い。 The connecting piece 909 is formed in an inverted V-shape in a side view with a central portion protruding upward, and both ends of the connecting piece 909 are located substantially at the center positions in the length direction of the locking pieces 908. It is connected to and installed. The connecting piece 909 inserts one end of the locking piece 908 from the cut portion 31 side of the eggshell 22 and locks the eggshell 22 when the inner surface 22 b of the eggshell 22 is locked. The bent vertex 909A of the connecting piece 909 comes into contact with and locks to the inner surface 22b of the shell, and even if the eggshell 22 is shaken by the locking of the vertex 909A and the locking piece 908 at two points. The eggshell 22 is locked so as not to come into contact with or be caught by the support 907. The connecting piece 909 may have any shape, such as an upwardly protruding arc, as long as the shape does not make contact with or catch on the column 907 even if the eggshell 22 shakes.
 したがって、乾燥用治具900Vの各支柱902の緩衝部材903のそれぞれに卵殻21を保持させるとともに、この乾燥用治具900Vの各支柱907のいずれか一方の係止片部908および連結片部909に卵殻22を係止させることによって、本体部11となる卵殻21と同時に、台座部12となる卵殻22を乾燥させることができるから、乾燥用治具900Vの使い勝手を向上できる。 Therefore, the eggshell 21 is held by each of the buffer members 903 of the columns 902 of the drying jig 900V, and the locking piece 908 and the connecting piece 909 of any one of the columns 907 of the drying jig 900V. By locking the eggshell 22 to the eggshell 21, the eggshell 22 to be the pedestal portion 12 can be dried at the same time as the eggshell 21 to be the main body portion 11, so that the usability of the drying jig 900 </ b> V can be improved.
[実施例]
 次に、本発明に係る容器10の製造工程において、コーティング層16,17として用いられるコーティング剤の実施例について詳細に説明する。なお、以下の説明においても、適宜図1ないし図4を参照する。
[Example]
Next, examples of the coating agent used as the coating layers 16 and 17 in the manufacturing process of the container 10 according to the present invention will be described in detail. In the following description, FIGS. 1 to 4 will be referred to as appropriate.
(実施例1:7.5重量%プルラン水溶液)
 まず、コーティング層16の第1の層18のコーティング剤として用いるプルラン水溶液として、プルラン(株式会社林原製)の含有率が純水に対し7.5重量%のプルラン試験液1を用意し、試験用容器に入れて保存した。同時に、シェラックとエタノールとが重量比で32:68の割合で混合されたシェラック液(ラックグレース32E:日本シェラック工業株式会社製)を用意した。このとき、外気温25℃で、湿度65%であった。
(Example 1: 7.5% by weight pullulan aqueous solution)
First, as an aqueous pullulan solution used as a coating agent for the first layer 18 of the coating layer 16, a pullulan test solution 1 containing 7.5% by weight of pullulan (manufactured by Hayashibara) with respect to pure water was prepared. And stored. At the same time, a shellac liquid (Luck Grace 32E: manufactured by Nippon Shellac Industrial Co., Ltd.) in which shellac and ethanol were mixed at a weight ratio of 32:68 was prepared. At this time, the external temperature was 25 ° C. and the humidity was 65%.
 次いで、切断部31にて切断した卵殻21を複数、例えば2個用意して卵殻A,Bとし、これら卵殻A,Bの開口部14を下方に向け、各卵殻A,Bの開口部14の開口縁に、約5~10mm程度の幅ほどプルラン試験液1が付着するように、これら卵殻A,Bの開口部14をプルラン試験液1に5秒間浸漬させた。 Next, a plurality of, for example, two eggshells 21 cut at the cutting portion 31 are prepared to form eggshells A and B, and the openings 14 of the eggshells A and B are directed downward, and the openings 14 of the eggshells A and B are formed. The openings 14 of the eggshells A and B were immersed in the pullulan test solution 1 for 5 seconds so that the pullulan test solution 1 adhered to the opening edge by a width of about 5 to 10 mm.
 この後、各卵殻A,Bの開口部14に付着しているプルラン試験液1の付着程度を目視にて確認し、プルラン試験液1が過剰に付着している場合には、卵殻A,Bの開口部14に付着しているプルラン試験液1を拭き取る等して、これら卵殻A,Bの開口部14に付着しているプルラン試験液1の量を調整した。 Thereafter, the degree of adhesion of the pullulan test solution 1 adhering to the openings 14 of the eggshells A and B is visually checked. If the pullulan test solution 1 is excessively adhered, the eggshells A and B are removed. The amount of the pullulan test solution 1 adhering to the openings 14 of the eggshells A and B was adjusted by, for example, wiping off the pullulan test solution 1 adhering to the openings 14.
 この状態で、各卵殻A,Bの開口部14を下方に向けた状態で、これら各卵殻A,Bを支柱(図示しない)にて係止し、例えばオーブン(製菓用オーブン:株式会社ワールド精機製)を用いて120℃の温度で、各卵殻A,Bの開口部14に付着しているプルラン試験液1を加熱乾燥させた。このとき、プルラン試験液1自身の自重により、卵殻A,Bの外表面21aに付着しているプルラン試験液1が下方へ移動していき、各卵殻A,Bの端面21cでのプルラン試験液1の厚みが厚くなることから、卵殻A,Bの外表面21aに薄く付着しているプルラン試験液1は約2分程度の加熱乾燥で乾燥するものの、各卵殻A,Bの端面21cに厚く付着しているプルラン試験液1は、乾燥するまでに、卵殻Aが6分30秒、および卵殻Bが7分30秒の時間を要した。 In this state, with the openings 14 of the eggshells A and B facing downward, the eggshells A and B are locked with a support (not shown), for example, an oven (confectionery oven: World Seiki Co., Ltd.) The pullulan test solution 1 attached to the openings 14 of the eggshells A and B was dried by heating at a temperature of 120 ° C. At this time, the pullulan test solution 1 adhering to the outer surface 21a of the eggshells A and B moves downward due to the weight of the pullulan test solution 1 itself, and the pullulan test solution on the end surface 21c of each of the eggshells A and B. Since the thickness of the pullulan test solution 1 attached to the outer surfaces 21a of the eggshells A and B is dried by heating and drying for about 2 minutes, the end surfaces 21c of the eggshells A and B are thicker. The attached pullulan test solution 1 took 6 minutes and 30 seconds for eggshell A and 7 minutes and 30 seconds for eggshell B before drying.
 そして、プルラン試験液1が乾燥し開口部14の開口縁に第1の層18が形成された各卵殻A,Bの開口部14を下方に向け、各卵殻A,Bの開口部14の開口縁に、約5~10mm程度の幅ほどシェラック液が付着するように、これら卵殻A,Bの開口部14をシェラック液に5秒間浸漬させた。よって、各卵殻A,Bの開口部14の開口縁に形成した第1の層18の表面全体にシェラック液が付着した状態となる。 Then, the opening 14 of each of the eggshells A and B in which the pullulan test solution 1 is dried and the first layer 18 is formed on the opening edge of the opening 14 is directed downward, and the opening of the opening 14 of each of the eggshells A and B is turned downward. The openings 14 of the eggshells A and B were immersed in the shellac liquid for 5 seconds so that the shellac liquid adhered to the rim at a width of about 5 to 10 mm. Accordingly, the shellac liquid adheres to the entire surface of the first layer 18 formed on the opening edge of the opening 14 of each of the eggshells A and B.
 この後、各卵殻A,Bの第1の層18上に付着しているシェラック液の付着程度を目視にて確認し、シェラック液が過剰に付着している場合には、卵殻A,Bの第1の層18上に付着しているシェラック液を拭き取る等して、各卵殻A,Bの第1の層18上に付着しているシェラック液の量を調整した。 Thereafter, the degree of adhesion of the shellac liquid adhering to the first layer 18 of each of the eggshells A and B is visually checked. The amount of the shellac liquid adhering on the first layer 18 of each of the eggshells A and B was adjusted by wiping off the shellac liquid adhering on the first layer 18, for example.
 この状態で、各卵殻A,Bの開口部14を下方に向けた状態で、これら各卵殻A,Bを支柱(図示しない)にて係止し、例えばオーブン(製菓用オーブン:株式会社ワールド精機製)を用いて120℃の温度で加熱して、各卵殻A,Bの第1の層18上のシェラック液を乾燥させた。このときもまた、シェラック液自身の自重により、卵殻A,Bの外表面21a部分に付着しているシェラック液が下方へ移動していき、各卵殻21の端面21cでのシェラック液の厚みが厚くなることから、卵殻21の外表面21aに薄く付着しているシェラック液は約1~2分程度の加熱乾燥で乾燥するものの、各卵殻A,Bの端面21cに厚く付着しているシェラック液は、乾燥するまでに5分間の時間を要した。この結果、各卵殻A,Bの開口部14の開口縁に第1の層18と第2の層19とが形成されコーティング層16となる。 In this state, with the openings 14 of the eggshells A and B facing downward, the eggshells A and B are locked with a support (not shown), for example, an oven (confectionery oven: World Seiki Co., Ltd.) Was heated at a temperature of 120 ° C. to dry the shellac liquid on the first layer 18 of each of the eggshells A and B. Also at this time, the shellac liquid adhering to the outer surfaces 21a of the eggshells A and B moves downward due to the weight of the shellac liquid itself, and the thickness of the shellac liquid at the end surface 21c of each eggshell 21 increases. Therefore, the shellac liquid thinly adhering to the outer surface 21a of the eggshell 21 is dried by heating and drying for about 1 to 2 minutes, but the shellac liquid thickly adhering to the end faces 21c of the eggshells A and B is It took 5 minutes to dry. As a result, the first layer 18 and the second layer 19 are formed on the opening edge of the opening 14 of each of the eggshells A and B to form the coating layer 16.
(実施例2~5:12.5~25重量%プルラン水溶液)
 次に、第1の層18のコーティング剤として用いるプルラン水溶液として、プルランの含有率が純水に対し12.5重量%、15.0重量%、17.5重量%、および25重量%と変化させたプルラン試験液2ないし5を用意した。そして、これらプルラン試験液2ないし5について、上記実施例1と同様の方法で、これらプルラン試験液2ないし5の乾燥に要する時間を、実施例2ないし5として行った。
(Examples 2 to 5: 12.5 to 25% by weight pullulan aqueous solution)
Next, as an aqueous pullulan solution used as a coating agent for the first layer 18, the content of pullulan was changed to 12.5% by weight, 15.0% by weight, 17.5% by weight, and 25% by weight based on pure water. Pullulan test solutions 2 to 5 were prepared. Then, with respect to these pullulan test solutions 2 to 5, the time required for drying these pullulan test solutions 2 to 5 was set as examples 2 to 5 in the same manner as in Example 1.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
 この結果、表1に示すように、プルラン含有率を純水に対し12.5重量%としたプルラン試験液2の場合は、プルラン試験液2が乾燥するまでに、卵殻Aが9分、および卵殻Bが9分30秒の時間を要した(実施例2)。また、プルラン含有率が15重量%のプルラン試験液3では、乾燥までに、卵殻Aが12分、および卵殻Bが12分30秒の時間を要した(実施例3)。さらに、プルラン含有率を17.5重量%としたプルラン試験液4では、乾燥までに、卵殻Aが14分、および卵殻Bが15分30秒の時間を要し(実施例4)、プルラン含有率を25重量%としたプルラン試験液5では、乾燥までに、卵殻Aが19分、および卵殻Bが18分の時間を要した(実施例5)。 As a result, as shown in Table 1, in the case of the pullulan test solution 2 in which the pullulan content was 12.5% by weight based on pure water, the eggshell A was 9 minutes before the pullulan test solution 2 was dried, and Eggshell B took 9 minutes and 30 seconds (Example 2). In the pullulan test solution 3 having a pullulan content of 15% by weight, it took 12 minutes for the eggshell A and 12 minutes and 30 seconds for the eggshell B to dry (Example 3). Further, in the pullulan test solution 4 in which the pullulan content was 17.5% by weight, the eggshell A and eggshell B required 14 minutes and 15 minutes and 30 seconds, respectively, to dry (Example 4). In the pullulan test solution 5 having a ratio of 25% by weight, eggshell A and eggshell B required 19 minutes and 18 minutes, respectively, before drying (Example 5).
 なお、卵殻A,Bの外表面21aに形成した第1の層18の表面に積層させたシェラック液が乾燥するまでの時間は、上記実施例1ないし5のいずれにおいても5分であり、一定の時間であった。 The time required for the shellac liquid laminated on the surface of the first layer 18 formed on the outer surface 21a of the eggshells A and B to dry is 5 minutes in any of Examples 1 to 5, and is constant. It was time.
 上記実施例1ないし5の結果、純水に対するプルランの含有率を17.5重量%より高くすると、卵殻21に対するプルランの付着量が多くなり過ぎ、卵殻21の端面21c部分にプルラン水溶液の液だまりができやすくなるため、卵殻21に付着させたプルラン水溶液の乾燥時間が長くなってしまう。これに対し、純水に対するプルランの含有率を12.5重量%より低くすると、卵殻21に対するプルランの付着性が低くなり過ぎてしまい、卵殻21の外表面21a等から第1の層18が剥がれやすくなってしまう。 As a result of Examples 1 to 5, when the content of pullulan with respect to pure water is higher than 17.5% by weight, the amount of pullulan adhered to the eggshell 21 becomes too large, and the pool of the aqueous solution of pullulan on the end face 21c of the eggshell 21. Therefore, the drying time of the aqueous pullulan solution attached to the eggshell 21 becomes longer. On the other hand, if the content of pullulan in pure water is lower than 12.5% by weight, the adhesion of the pullulan to the eggshell 21 becomes too low, and the first layer 18 is peeled off from the outer surface 21a of the eggshell 21 or the like. It will be easier.
 したがって、卵殻21に対する付着性および乾燥時間の観点から、純水に対するプルランの含有率は12.5重量%以上17.5重量%以下が好ましいことが分かった。さらに、純水に対するプルランの含有率を15重量%とすると、卵殻21に対して適切な付着性を確保でき比較的短時間で乾燥できるから、特に好ましいことが分かった。 Therefore, it was found that the pullulan content in pure water is preferably 12.5% by weight or more and 17.5% by weight or less from the viewpoint of the adhesion to the eggshell 21 and the drying time. Furthermore, it was found that when the content of pullulan with respect to pure water was 15% by weight, it was particularly preferable because appropriate adhesion to the eggshell 21 could be ensured and drying could be performed in a relatively short time.
