Description

本発明は、改ざん防止容器の構造に関し、特に容器をいったん封止した後の開封の有無を容易に判別可能な改ざん防止容器の構造に関する。 The present invention relates to a structure of a tamper-proof container, and more particularly to a structure of a tamper-proof container that can easily determine whether or not the container has been opened once the container is sealed.

例えば、惣菜、弁当、菓子等の食品包装のための容器の多くは容器本体と蓋体から構成される。内容物を容器内に詰め込んだ後、容器本体に蓋体が被せられる。単純な構造の容器では容器本体と蓋体が重ね合わされているに過ぎず、簡単に双方は分離してしまう。そのため、陳列、販売時、簡単に蓋が開いて開封するようでは、容器内への異物混入等のおそれが懸念される。不適切な物品の販売は販売者の信用問題にも及ぶため、販売者は販売物品について細心の注意を払っている。 For example, many containers for food packaging such as sugar beet, lunch boxes and confectionery are composed of a container body and a lid. After the contents are packed in the container, the container body is covered with a lid. In a container having a simple structure, the container main body and the lid are merely superimposed, and both are easily separated. Therefore, at the time of display and sale, if the lid is easily opened and opened, there is a concern that foreign matter may enter the container. Sellers pay close attention to items for sale because the sale of inappropriate items extends to sellers' credit problems.

従来、容器の封止に際し、容器本体に蓋を被せた後、テープやシール等を用いて複数箇所を貼り付けて封止していた。ところが、容器本体と蓋体との密着量の少ない部位が生じるため、異物混入を抑止できるほど封止の効果は十分ではない。 Conventionally, when a container is sealed, the container body is covered with a lid, and then a plurality of locations are pasted and sealed using a tape or a seal. However, since a portion having a small amount of adhesion between the container main body and the lid body is generated, the sealing effect is not sufficient to prevent contamination by foreign matters.

そのため、容器全体が被覆され蓋が開かないようにするべく、ラップフィルムによる被覆が増えている。ラップフィルムを用いた被覆によると、封止効果は高まり、衝撃にも強く、取り扱いやすくなり陳列作業の利便性が高まる。そのため、コンビニエンスストア等で販売される弁当類に多く採用されている。 For this reason, wrap film coverage is increasing to cover the entire container and prevent the lid from opening. According to the covering using the wrap film, the sealing effect is enhanced, it is resistant to impacts, is easy to handle, and the convenience of display work is enhanced. For this reason, it is widely used for lunch boxes sold at convenience stores.

しかしながら、テープやシール、ラップフィルムを使用する場合、容器以外に資材の経費が生じる。また、テープやシールの貼り付け、またはラップフィルムによる包み込みのための作業も不可避的に別途生じる。加えて、容器の封止作業自体に時間を要することから、商品の充填、陳列等の販売に関する生産性は必ずしも良くない。このことから、資材の簡素化と作業効率の改善が求められてきた。 However, when a tape, a seal, or a wrap film is used, material costs other than the container are generated. In addition, work for attaching a tape or a seal or wrapping with a wrap film is inevitably separately generated. In addition, since the container sealing operation itself takes time, productivity related to sales such as product filling and display is not always good. For this reason, simplification of materials and improvement of work efficiency have been demanded.

そこで、極力、容器本体及び蓋体のみによって封止の精度を高めた容器が提案されている（特許文献１等参照）。特許文献１の容器によると、容器本体に蓋体を重ねて合着した際、容器本体の縁部分よりも蓋体の縁部分が長く垂下する。そして、容器本体の側壁部は蓋体の垂下した縁部分により覆われる。当該容器によると、容器本体と蓋体の合着後、蓋体が容器本体側に深く被さるため、ちょうど容器本体の周囲に蓋体の防護壁が生じるようになる。そのため、指等は差し込み難くなり不用意に開けることは難しく、異物混入の抑止に対して効果が高まる。 In view of this, there has been proposed a container whose sealing accuracy is enhanced only by the container main body and the lid (see Patent Document 1, etc.). According to the container of Patent Document 1, when the lid body is overlapped and bonded to the container body, the edge portion of the lid body hangs longer than the edge portion of the container body. And the side wall part of a container main body is covered with the edge part which the cover body hung down. According to the container, since the lid body covers the container body side deeply after the container body and the lid body are joined, a protective wall of the lid body is generated just around the container body. For this reason, it is difficult to insert a finger or the like and it is difficult to open carelessly, and the effect is increased against deterring foreign matter.

しかしながら、蓋体は容器本体側に垂下しているのみであるため、いったん容器本体と合着した蓋体を取り外すことは不可能ではない。そのため、不正目的により蓋体が開封されたか否かについて事後的に確認し難いという問題点があった。 However, since the lid body only hangs down on the container body side, it is not impossible to remove the lid body once attached to the container body. Therefore, there has been a problem that it is difficult to confirm later whether or not the lid has been opened for illegal purposes.

このようなことから、特別な資材等を必要とせず、蓋体と容器本体との合着の精度に優れ、かつ、蓋体が容器本体から外された場合にその痕跡が明らかとなり、不正行為に対する改ざん防止の構造を備えた容器が求められるに至った。 Because of this, no special materials are required, the accuracy of the attachment between the lid and the container body is excellent, and when the lid is removed from the container body, the trace becomes clear and fraudulent Therefore, a container having a structure for preventing falsification has been demanded.

第１実施例の改ざん防止容器１は、第１容体１０と第２容体５０の組み合わせにより構成される。この例の改ざん防止容器１では、第１容体１０は容器本体Ｃであり、第２容体５０は蓋体Ｔであり、第１容体１０に第２容体５０が載る上下関係であり、第２容体５０による外嵌合の形態である。食品や物品等は第１容体１０側に詰め込まれ、その後、第２容体５０は第１容体１０に被せられる。そして、本発明の特徴として、第２容体５０側に改ざん防止構造Ｓｒが備えられる。改ざん防止構造Ｓｒにより、第１容体１０と第２容体５０との十分な合着が可能となるとともに、いったん封止が解かれた後の開封の痕跡が発見されやすくなる。図１中の残余の符号を含め、改ざん防止構造についての詳細は後述する。 The tamper-proof container 1 of the first embodiment is configured by a combination of a first container 10 and a second container 50. In the tamper-proof container 1 of this example, the first container 10 is the container body C, the second container 50 is the lid T, and the second container 50 is in a vertical relationship in which the second container 50 is placed on the first container 10. 50 is a form of external fitting. Foods, articles and the like are packed on the first container 10 side, and then the second container 50 is put on the first container 10. As a feature of the present invention, a tamper-proof structure Sr is provided on the second container 50 side. The tamper-proof structure Sr enables sufficient bonding between the first container 10 and the second container 50, and makes it easier to find an opening trace after the seal is once released. Details of the tamper-proof structure, including the remaining symbols in FIG. 1, will be described later.

図２は組み合わせ前の改ざん防止容器１の上方から見た平面図であり、第１容体１０については容器本体Ｃの内面側が示され、第２容体５０については蓋体Ｔの外面側が示される。図示から把握されるように、第１容体１０では、開口部１１の全周囲１２に当該容体の容器本体部１３の外方へ延設した第１フランジ部２０が備えられる。第２容体５０でも、開口部５１の全周囲５２に当該容体の容器本体部５３の外方へ延設した第２フランジ部６０が備えられる。第１容体１０の平板部１４は容器本体Ｃにおける底部となる。第２容体５０の平板部５４は蓋体Ｔにおける天板となる。 FIG. 2 is a plan view of the tamper-proof container 1 before combination, as viewed from above. The first container 10 shows the inner surface side of the container body C, and the second container 50 shows the outer surface side of the lid T. As can be seen from the drawing, the first container 10 is provided with a first flange portion 20 that extends outward from the container body 13 of the container around the entire periphery 12 of the opening 11. The second container 50 is also provided with a second flange portion 60 that extends outward from the container body 53 of the container around the entire periphery 52 of the opening 51. The flat plate portion 14 of the first container 10 is a bottom portion of the container main body C. The flat plate portion 54 of the second container 50 is a top plate in the lid T.

図示の例によると、第１容体１０及び第２容体５０のそれぞれの開口部１１，５１は、ともに平面視円形である。円形形状とすることにより、容器周囲のどの部位であっても加わる荷重が平均化され、変形耐性が高まる。また、第２フランジ部６０には易破壊部７０が設けられている。そして、易破壊部７０は同第２フランジ部６０の全周にわたって設けられている。 According to the illustrated example, the openings 11 and 51 of the first container 10 and the second container 50 are both circular in plan view. By adopting a circular shape, the load applied to any part around the container is averaged, and deformation resistance is increased. The second flange portion 60 is provided with an easily breakable portion 70. The easily breakable portion 70 is provided over the entire circumference of the second flange portion 60.

図３は改ざん防止容器１の全体縦断面図であり、容器本体Ｃの第１容体１０に蓋体Ｔの第２容体５０を重ねた状態である。第２容体５０の第２フランジ部６０は、第１容体１０の第１フランジ部２０に対して合着される。双方の組み合わせにより改ざん防止容器１は構成される。フランジ部同士は面接触するため、当該容器１の内部の封止は良好となる。第２フランジ部６０の周囲に備えられる改ざん防止構造Ｓｒは、被覆周壁部６３とこれに接続する折り返し端部６５を含む折り返し状の構造である。 FIG. 3 is an overall vertical cross-sectional view of the tamper-proof container 1, and shows a state in which the second container 50 of the lid T is overlapped with the first container 10 of the container main body C. The second flange portion 60 of the second container 50 is joined to the first flange portion 20 of the first container 10. The tamper-proof container 1 is configured by a combination of both. Since the flange portions are in surface contact, the inside of the container 1 is well sealed. The tamper-proof structure Sr provided around the second flange portion 60 is a folded structure including a covering peripheral wall portion 63 and a folded end portion 65 connected thereto.

また、改ざん防止構造Ｓｒを備える第２容体は、合成樹脂を主体とするシート状物の成形体からなる。合成樹脂のシート状物を用いることによっては、改ざん防止構造Ｓｒを備える第２容体は安価かつ精度良く製造される。具体的には、ポリエチレン、ポリプロピレン、ポリスチレン、ポリエチレンテレフタレート等の熱可塑性樹脂のシート（合成樹脂シート）、さらにはポリ乳酸等の生分解性の熱可塑性樹脂のシートである。合成樹脂シートの厚さは適宜ではあるものの、概ね１ｍｍ以下の厚さである。そして、前記の合成樹脂シートは真空成形により図示をはじめとする形状に成形される。開口部と天板となる平板部を有するすり鉢状の容器形状の場合、合成樹脂シートを原料とした際の成形時の量産性、加工精度等を考慮すると真空成形が簡便かつ最適である。 Further, the second container including the tamper-proof structure Sr is formed of a sheet-like molded body mainly composed of synthetic resin. By using a synthetic resin sheet, the second container having the tamper-proof structure Sr is inexpensively and accurately manufactured. Specifically, it is a sheet of a thermoplastic resin such as polyethylene, polypropylene, polystyrene, or polyethylene terephthalate (synthetic resin sheet), or a sheet of a biodegradable thermoplastic resin such as polylactic acid. Although the thickness of the synthetic resin sheet is appropriate, it is approximately 1 mm or less. And the said synthetic resin sheet | seat is shape | molded in the shape including illustration by vacuum forming. In the case of a mortar-shaped container having a flat plate portion serving as an opening and a top plate, vacuum molding is simple and optimal in consideration of mass productivity at the time of molding when using a synthetic resin sheet as a raw material, processing accuracy, and the like.

これに対し、第１フランジ部２０を形成できる限り、改ざん防止容器１における第１容体１０の材質は特段限定されない。例えば、金属製、ガラス製、木製であっても良い。あるいは、樹脂の成型品等でも良い。すなわち、第１容体は何回も使用する容器とし、これに組み合わせる第２容体のみ前述の合成樹脂シート製として使い捨て（ディスポーザブル）とすることができる。こうしても、改ざん防止構造自体の機能は同様であるため、本発明の所望の目的を達することはできる。 On the other hand, as long as the 1st flange part 20 can be formed, the material of the 1st container 10 in the tamper-proof container 1 is not specifically limited. For example, it may be made of metal, glass or wood. Alternatively, a resin molded product or the like may be used. That is, the first container can be a container that is used many times, and only the second container combined therewith can be made disposable as a product made of the above-mentioned synthetic resin sheet. Even in this case, since the function of the tamper-proof structure itself is the same, the desired object of the present invention can be achieved.

むろん、第２容体とともに、第１容体も前述の合成樹脂を主体とするシート状物の成形体として真空成形により成形することができる。こうすると、第１容体も簡便に成形でき、当該改ざん防止容器自体を安価に製造可能である。また、いずれも使い捨て（ディスポーザブル）とすることができる。第１容体と第２容体の組み合わせにおいて、合成樹脂シートの原料樹脂を同一種類としても異なる種類としてもよい。樹脂の種類は用途、内容物、包装対象により適宜選択される。 Of course, together with the second container, the first container can be formed by vacuum forming as a sheet-like formed body mainly composed of the above-mentioned synthetic resin. If it carries out like this, a 1st container can also be shape | molded simply and the said tamper-proof container itself can be manufactured cheaply. Moreover, all can be made disposable (disposable). In the combination of the first container and the second container, the raw resin of the synthetic resin sheet may be the same or different. The type of resin is appropriately selected depending on the application, contents, and packaging target.

図４は改ざん防止容器１の主要部断面図である。同図を用いさらに改ざん防止構造Ｓｒ付近の構造を説明する。図示の第１容体１０によると、第１フランジ部２０のフランジ端部２１に曲げ縁部２２が形成されている。曲げ縁部２２を備えることにより、第１容体１０の開口部１１付近は変形し難くなる。第２容体５０との組み合わせによる合着の不具合を少なくすることができる。 FIG. 4 is a cross-sectional view of the main part of the tamper-proof container 1. The structure in the vicinity of the falsification preventing structure Sr will be described with reference to FIG. According to the illustrated first container 10, the bent edge portion 22 is formed at the flange end portion 21 of the first flange portion 20. By providing the bent edge 22, the vicinity of the opening 11 of the first container 10 is hardly deformed. It is possible to reduce the problem of coalescence due to the combination with the second container 50.

第２容体５０の第２フランジ部６０には、フランジ本体部６２と、同フランジ本体部６２と直交し第１容体１０側に伸長する被覆周壁部６３が備えられる。図示の被覆周壁部６３は第１容体１０側への垂下である。そして、第１容体１０と第２容体５０の合着時、第１容体１０の第１フランジ部２０のフランジ端部２１は、フランジ本体部６２と被覆周壁部６３の折れ曲がり構造により覆われる。さらに、フランジ端部２１に設けられた曲げ縁部２２に対しても被覆周壁部６３は横から被さる。 The second flange portion 60 of the second container 50 includes a flange main body portion 62 and a covering peripheral wall portion 63 that is orthogonal to the flange main body portion 62 and extends toward the first container 10 side. The illustrated coating peripheral wall 63 is depending on the first container 10 side. When the first container 10 and the second container 50 are joined, the flange end portion 21 of the first flange portion 20 of the first container 10 is covered with the bent structure of the flange main body portion 62 and the covering peripheral wall portion 63. Further, the covering peripheral wall 63 covers the bent edge 22 provided at the flange end 21 from the side.

被覆周壁部６３の伸長した末端となる端部６４には、被覆周壁部６３の伸長方向と逆に第２容体５０側に折り返された折り返し端部６５が備えられる。図示の例では、折り返し端部６５は幅部６７を介して接続される。幅部６７は、適度に折り返し端部６５を被覆周壁部６３から間隔を離すために備えられる。また、後述する容体同士の嵌め合わせやすさの便宜でもある。 An end portion 64 that is an extended end of the covering peripheral wall portion 63 is provided with a folded end portion 65 that is turned back toward the second container 50 in the direction opposite to the extending direction of the covering peripheral wall portion 63. In the illustrated example, the folded end portion 65 is connected via a width portion 67. The width portion 67 is provided for appropriately separating the folded end portion 65 from the covering peripheral wall portion 63. Further, it is also convenient for fitting the containers to be described later.

第１フランジ部２０の係合面２９に第２フランジ部６０の係合面６９が接触する。そして、折り返し端部６５は第１フランジ部２０の背面部２３と係合可能となる。このように、改ざん防止構造Ｓｒによると、第２容体５０の第２フランジ部６０（被覆周壁部６３、折り返し端部６５）が第１容体１０の第１フランジ部２０を巻き込むようにして被さる。従って、極めて単純な形状でありながら、いったん容体同士が嵌合した後、容体同士は容易に外れなくなる。また、無理に第１容体１０と第２容体５０を引き離そうとすると、第２フランジ部６０の被覆周壁部６３及び折り返し端部６５の構造を破壊することになる。それゆえ、改ざん防止構造Ｓｒの破壊の痕跡から、不正開封の把握が容易となる。 The engagement surface 69 of the second flange portion 60 contacts the engagement surface 29 of the first flange portion 20. The folded end portion 65 can be engaged with the back surface portion 23 of the first flange portion 20. As described above, according to the tamper-proof structure Sr, the second flange portion 60 (the covering peripheral wall portion 63 and the folded end portion 65) of the second container 50 covers the first flange portion 20 of the first container 10 so as to be wound around. Therefore, although the shapes are extremely simple, the containers cannot be easily detached after the containers are once fitted. Further, if the first container 10 and the second container 50 are forcibly separated, the structures of the covering peripheral wall 63 and the folded end 65 of the second flange 60 will be destroyed. Therefore, the tampering structure Sr can be easily grasped from the trace of the destruction.

図５は第２容体５０の第２フランジ部６０の部分拡大図である。同図（ａ）及び（ｂ）から把握されるように、折り返し端部６５にローレット溝部６６が形成されている。このローレット溝部はナーリングとも称され、被覆周壁部６３の伸長方向と同じ縦方向に、列状の微細な溝として刻設される。図示では、溝の一部は被覆周壁部６３にも延長されている。このローレット溝部６６の形成に際しては公知の刻設器具が用いられる。 FIG. 5 is a partially enlarged view of the second flange portion 60 of the second container 50. As can be understood from FIGS. 5A and 5B, a knurled groove 66 is formed in the folded end 65. This knurled groove portion is also referred to as knurling, and is engraved as a row of fine grooves in the same vertical direction as the extending direction of the covering peripheral wall portion 63. In the drawing, a part of the groove is also extended to the covering peripheral wall portion 63. In forming the knurled groove 66, a known engraving tool is used.

前掲図４等の第２フランジ部６０における被覆周壁部６３と折り返し端部６５との折り返し構造から理解されるように、折り返し端部６５を内側に折り曲げる際、直径に差が生じる。つまり、折り返し端部６５側は被覆周壁部６３と比較して収縮される。収縮の影響から、ローレット溝部を設けないままの平板状であれば、不規則な皺や変形が折り返し端部６５に発生し、成形品としての第２容体の寸法精度に歪みが生じやすくなる。 As can be understood from the folded structure of the covering peripheral wall portion 63 and the folded end portion 65 in the second flange portion 60 shown in FIG. 4 and the like, when the folded end portion 65 is folded inward, a difference in diameter occurs. That is, the folded end portion 65 side is contracted as compared with the covering peripheral wall portion 63. If the flat plate shape is not provided with the knurled groove portion due to the shrinkage, irregular wrinkles and deformation occur in the folded end portion 65, and the dimensional accuracy of the second container as a molded product is likely to be distorted.

これに対し、折り返し端部６５にローレット溝部６６が設けられると、折り返し端部６５の形成し際し、当該ローレット溝部６６が蛇腹状に（アコーディオンのように）折れ曲がる。結果、歪み変形はローレット溝部６６によって吸収される。つまり、折り返し端部６５自体に生じる歪みは軽減され、被覆周壁部６３及び折り返し端部６５の変形を抑制することができる。 On the other hand, when the knurled groove portion 66 is provided in the folded end portion 65, the knurled groove portion 66 is bent in a bellows shape (like an accordion) when the folded end portion 65 is formed. As a result, distortion deformation is absorbed by the knurled groove 66. That is, distortion generated in the folded end portion 65 itself is reduced, and deformation of the covering peripheral wall portion 63 and the folded end portion 65 can be suppressed.

この発明の改ざん防止容器にあっては、前述のとおりいったん容体同士が嵌合した後は、改ざん防止構造を破壊しなければ容体同士を取り外すことはできない。そうすると、本来の容器の開封時には不便である。そこで、予め、改ざん防止構造を解除する機構も備えられる。具体的には、第２フランジ部６０の同第２フランジ部６０を破壊するための易破壊部７０が設けられる（図１，２等参照）。つまり、易破壊部７０を通じて、改ざん防止構造Ｓｒである第２フランジ部６０の被覆周壁部６３及び折り返し端部６５が第１容体１０の第１フランジ部２０から引き離されることである。前掲の図２の例では、易破壊部７０は同第２フランジ部６０の全周にわたって設けられている。このため、どこからでも簡単に第２フランジ部６０を破壊できる。 In the tamper-proof container according to the present invention, after the containers are once fitted as described above, the containers cannot be removed unless the tamper-proof structure is destroyed. This is inconvenient when the original container is opened. Therefore, a mechanism for releasing the tamper-proof structure is provided in advance. Specifically, an easily breakable portion 70 for breaking the second flange portion 60 of the second flange portion 60 is provided (see FIGS. 1 and 2). That is, the covering peripheral wall portion 63 and the folded end portion 65 of the second flange portion 60 that are the tamper-proof structure Sr are pulled away from the first flange portion 20 of the first container 10 through the easily breakable portion 70. In the example of FIG. 2 described above, the easily breakable portion 70 is provided over the entire circumference of the second flange portion 60. For this reason, the 2nd flange part 60 can be destroyed easily from anywhere.

図５（ａ）によると、易破壊部７０は第２フランジ部６０のフランジ本体部６２に設けられる（フランジ破壊部７１）。当該易破壊部７０（７１）の配置ではフランジ本体部６２に対し、簡単に同易破壊部７０を形成することができる。フランジ本体部６２は平板状の部位であることから易破壊部形成の加工は容易である。また、図５（ｂ）によると、易破壊部７０は第２フランジ部６０の被覆周壁部６３に設けられる（周壁破壊部７２）。この配置の場合、易破壊部７０（７２）は被覆周壁部６３の端付近（端部６４）から近く、比較的外部から容易に易破壊部７０に力が到達しやすい。なお、易破壊部の場所は、容体の形状、大きさ、容体の材質や強度等を勘案して規定される。 According to Fig.5 (a), the easily breakable part 70 is provided in the flange main-body part 62 of the 2nd flange part 60 (flange fracture part 71). In the arrangement of the easily breakable portion 70 (71), the easily breakable portion 70 can be easily formed with respect to the flange main body portion 62. Since the flange main body 62 is a flat plate-like part, it is easy to form the easily breakable part. Moreover, according to FIG.5 (b), the easily breakable part 70 is provided in the covering surrounding wall part 63 of the 2nd flange part 60 (peripheral wall breaking part 72). In this arrangement, the easily breakable portion 70 (72) is close to the end vicinity (end portion 64) of the covering peripheral wall portion 63, and the force easily reaches the easily breakable portion 70 from the outside relatively easily. The location of the easily breakable portion is defined in consideration of the shape and size of the container, the material and strength of the container, and the like.

図６は、第２フランジ部６０の主要部拡大断面図である。同図を用い、易破壊部７０の詳細を説明する。図６（ａ）に開示の易破壊部７０は肉薄部７４である。肉薄部７４はフランジ本体部６２の一面側のみに形成されている。図６（ｂ）の開示の易破壊部７０も肉薄部７４である。この例の肉薄部７４はフランジ本体部６２の両面側に形成されている。いずれにおいても、肉薄部７４の部分のみ、フランジ本体部６２の他の部位より厚さが薄くなっている。図６（ｃ）によると、易破壊部７０はフランジ本体部６２を上下に貫通する貫通孔部７６である。この貫通孔部７６は連続して形成されているのではなく、点列状または間欠した線状に構成される。貫通孔部７６の部分が多くなりすぎると、第２フランジ部６０の強度は極端に低下するためである。 FIG. 6 is an enlarged cross-sectional view of the main part of the second flange portion 60. Details of the easy-to-break portion 70 will be described with reference to FIG. The easily breakable portion 70 disclosed in FIG. 6A is a thin portion 74. The thin portion 74 is formed only on one surface side of the flange main body portion 62. The easily breakable portion 70 disclosed in FIG. 6B is also a thin portion 74. The thin portions 74 in this example are formed on both sides of the flange main body 62. In any case, only the thin portion 74 is thinner than other portions of the flange main body 62. According to FIG.6 (c), the easily breakable part 70 is the through-hole part 76 which penetrates the flange main-body part 62 up and down. The through-hole portion 76 is not formed continuously, but is configured in a dot line shape or an intermittent line shape. This is because the strength of the second flange portion 60 is extremely reduced when the number of the through-hole portions 76 is excessive.

従って、第２フランジ部６０は易破壊部７０の肉薄部７４または貫通孔部７６において構造強度は意図的に弱められる。この結果、軽度の操作により易破壊部７０を通じて第２フランジ部６０は破壊される。肉薄部７４の溝の深さ、貫通孔部７６の間隔等は、第２容体の形状、大きさ、容体の材質や強度等を勘案して規定される。なお、図示の肉薄部７４または貫通孔部７６は例示であり、開示以外の形状、形態も許容される。また、形成場所は図示のフランジ本体部６２とする他に、被覆周壁部６３に設けることもできる（図示せず）。 Accordingly, the structural strength of the second flange portion 60 is intentionally weakened in the thin portion 74 or the through hole portion 76 of the easily breakable portion 70. As a result, the second flange portion 60 is broken through the easy-to-break portion 70 by a slight operation. The depth of the groove of the thin portion 74, the interval between the through-hole portions 76, and the like are defined in consideration of the shape and size of the second container, the material and strength of the container, and the like. The illustrated thin portion 74 or through-hole portion 76 is merely an example, and shapes and forms other than those disclosed are allowed. In addition to the flange main body portion 62 shown in the figure, the formation location can also be provided on the covering peripheral wall portion 63 (not shown).

続いて示す図７も第２容体５０の第２フランジ部６０の部分拡大図である。同図を用い、易破壊部７０の破壊操作を円滑、かつ簡便にする機構を説明する。これまでの説明から理解されるように、第２容体５０において第２フランジ部６０の周囲の被覆周壁部６３は直交しており構造強度が高められている。さらに、折り返し端部６５も備えられているため、構造上、破壊や変形に対して耐性が備わっている。そのため、たとえ易破壊部７０が備えられていても、そこに容易に到達できるような機構がなければ、易破壊部７０は活用されない。そこで、第２フランジ部６０には、当該第２フランジ部を破壊するための契機となる起点部８０が設けられている。 FIG. 7 shown next is also a partially enlarged view of the second flange portion 60 of the second container 50. A mechanism that makes the breaking operation of the easy-to-break portion 70 smooth and simple will be described with reference to FIG. As understood from the above description, in the second container 50, the covering peripheral wall portion 63 around the second flange portion 60 is orthogonal, and the structural strength is enhanced. Further, since the folded end portion 65 is also provided, the structure is resistant to destruction and deformation. Therefore, even if the easy-to-break portion 70 is provided, the easy-to-break portion 70 is not utilized unless there is a mechanism that can easily reach the easily-breakable portion 70. Therefore, the second flange portion 60 is provided with a starting point portion 80 that serves as an opportunity for destroying the second flange portion.

図７（ａ）の起点部８０は切り欠き部８２であり、三角形状の切れ込み（ノッチ）が被覆周壁部６３に形成されている。図７（ｂ）の起点部８０は突片部８４であり、板状の舌片が被覆周壁部６３に備えられる。図７（ｃ）の起点部８０は着色部であり、第２フランジ部の他の部位と識別可能な色に、被覆周壁部６３の必要部分は着色される。起点部８０のそれぞれの構造８２，８４，８６により、被覆周壁部６３において破壊の起点となる部分は目立ち、利用者の視覚を通じて認識され易くなる。 The starting point 80 in FIG. 7A is a notch 82, and a triangular cut (notch) is formed in the covering peripheral wall 63. The starting point 80 in FIG. 7B is a projecting piece 84, and a plate-like tongue piece is provided on the covering peripheral wall 63. The starting point portion 80 in FIG. 7C is a colored portion, and a necessary portion of the covering peripheral wall portion 63 is colored in a color that can be distinguished from other portions of the second flange portion. Due to the respective structures 82, 84, 86 of the starting point portion 80, the portion that becomes the starting point of the breakage in the covering peripheral wall portion 63 is conspicuous and is easily recognized through the visual sense of the user.

容器の開封時、特に第２容体５０を第１容体１０から取り外そうする場合、起点部８０（８２，８４，８６）が目印となる。この付近の被覆周壁部６３は利用者の左右の指でつまみ上げられ、互い違いの方向（例えば紙面手前側と奥手側）にずらされる。特に、図示のように、各起点部８０に加えて前述の易破壊部７０と同構造の誘導部８１も備えられている。起点部８０と易破壊部７０は誘導部８１により接続されるため、起点部８０（８２，８４，８６）を目安に加わった力は最初に誘導部８１に伝わるとともに当該誘導部８１が破壊される。この力は円滑に易破壊部７０にまで到達し、順次易破壊部７０自体も破壊される。こうして、最終的に第２フランジ部６０が破壊され、第１容体１０と第２容体５０との封止は解除される。 When the container is opened, particularly when the second container 50 is to be removed from the first container 10, the starting point 80 (82, 84, 86) serves as a mark. The covering peripheral wall portion 63 in the vicinity is picked up by the left and right fingers of the user and is shifted in alternate directions (for example, the front side and the back side). In particular, as shown in the drawing, in addition to each starting point portion 80, a guide portion 81 having the same structure as the above-described easily breakable portion 70 is also provided. Since the starting point portion 80 and the easily breakable portion 70 are connected by the guiding portion 81, the force applied to the starting point portion 80 (82, 84, 86) is first transmitted to the guiding portion 81 and the guiding portion 81 is broken. The This force smoothly reaches the easy-to-break part 70, and the easy-to-break part 70 itself is sequentially destroyed. Thus, the second flange portion 60 is finally destroyed, and the sealing of the first container 10 and the second container 50 is released.

ここで図８ないし図１１を用い、第１容体１０と第２容体５０の組み合わせの様子と無理に引き離したときの様子を説明する。図８ないし図１１の各図とも、第１フランジ部２０及び第２フランジ部６０の主要部分縦端面図である。主要部分をわかりやすくするため、端面図とした。図８は第１容体１０及び第２容体５０の組み合わせ前の分離状態である。各部位の説明は図４にて説明のとおりであるため、詳細は省略する。 Here, the state of the combination of the first container 10 and the second container 50 and the state when they are forcibly separated will be described with reference to FIGS. 8 to 11 are main part longitudinal end views of the first flange portion 20 and the second flange portion 60. In order to make the main part easy to understand, an end view is used. FIG. 8 shows a separated state before the first container 10 and the second container 50 are combined. Since the description of each part is as described with reference to FIG.

図９は、第１容体１０に第２容体５０を押しつけ、双方を合着させる直前の状態である。はじめに第２フランジ部６０の被覆周壁部６３及び折り返し端部６５は、第１容体１０に設けられた第１フランジ部２０のフランジ端部２１及び曲げ縁部２２と接触する。このとき、被覆周壁部６３及び折り返し端部６５は当初の状態（図８）よりも、わずかに押し潰されるとともに容体の外方に広がるように変形する。第２容体５０は合成樹脂のシート状物からなる成形体であるため、図示のような可撓変形は容易である。この変形により、第１フランジ部２０は被覆周壁部６３の内側に受け入れ可能となる。 FIG. 9 shows a state immediately before the second container 50 is pressed against the first container 10 and both are bonded together. First, the covering peripheral wall portion 63 and the folded end portion 65 of the second flange portion 60 are in contact with the flange end portion 21 and the bending edge portion 22 of the first flange portion 20 provided in the first container 10. At this time, the covering peripheral wall portion 63 and the folded end portion 65 are slightly crushed and deformed so as to spread outward from the original state (FIG. 8). Since the second container 50 is a molded body made of a synthetic resin sheet, flexible deformation as shown is easy. By this deformation, the first flange portion 20 can be received inside the covering peripheral wall portion 63.

図１０は、第１容体１０に第２容体５０を合着させて組み合わせが完了した状態である。第２容体５０の被覆周壁部６３及び折り返し端部６５は、第１フランジ部２０のフランジ端部２１及び曲げ縁部２２を抱え込む。そして、被覆周壁部６３及び折り返し端部６５は樹脂弾性の復元力により当初の状態（図８参照）に復帰する。図示から把握されるように、第２フランジ部６０の折り返し端部６５は、鉤状となり第１フランジ部２０の背面部２３を支える。この関係から、第１フランジ部２０は、第２フランジ部６０のフランジ本体部６２及び折り返し端部６５の上下両方向から挟まれ、両フランジ部同士による固定性能は高められる。 FIG. 10 shows a state where the second container 50 is attached to the first container 10 and the combination is completed. The covering peripheral wall portion 63 and the folded end portion 65 of the second container 50 enclose the flange end portion 21 and the bent edge portion 22 of the first flange portion 20. And the coating | coated surrounding wall part 63 and the folding | turning edge part 65 return to the original state (refer FIG. 8) by the restoring force of resin elasticity. As can be seen from the drawing, the folded end portion 65 of the second flange portion 60 has a hook shape and supports the back surface portion 23 of the first flange portion 20. From this relationship, the first flange portion 20 is sandwiched from both the upper and lower directions of the flange main body portion 62 and the folded end portion 65 of the second flange portion 60, and the fixing performance by the two flange portions is enhanced.

図１１は、第１容体１０から第２容体５０を無理矢理引き離した状態である。すなわち、不正に容器が開封された状態である。第１容体１０から第２容体５０を分離しようとするとき、第１フランジ部２０のフランジ端部２１及び曲げ縁部２２が折り返し端部６５に引っかかるため、そのままでは第１フランジ部２０（曲げ縁部２２）は折り返し端部６５から外れない。ところが、第２容体５０を第１容体１０から強引に引き離してしまうと、第２容体５０の被覆周壁部６３及び折り返し端部６５は、巻き込んでいる第１フランジ部２０のフランジ端部２１及び曲げ縁部２２の抵抗を受けて図示のように不自然に変形してしまう。第２フランジ部６０は歪み変形可能な状態を通過して降伏状態になったといえる。 FIG. 11 shows a state in which the second container 50 is forcibly separated from the first container 10. That is, the container has been opened illegally. When the second container 50 is to be separated from the first container 10, the flange end 21 and the bent edge 22 of the first flange 20 are caught by the folded end 65. Part 22) does not come off the folded end 65. However, if the second container 50 is forcibly pulled away from the first container 10, the covering peripheral wall portion 63 and the folded end portion 65 of the second container 50 are bent and the bent end portion 21 of the first flange portion 20 and the bent end portion 21 are bent. Due to the resistance of the edge 22, it deforms unnaturally as shown. It can be said that the 2nd flange part 60 passed through the state which can be distorted, and became the yielding state.

いったん第２フランジ部６０の折り返し端部６５が降伏状態となってしまうと当初の状態（図８参照）に復帰できないため、不正開封の痕跡を隠滅することはできない。従って、図示の状態の第２容体５０の第２フランジ部６０周辺の構造を確認すれば、不正な開封が行われたか否かの確認を簡単に行うことができる。本発明における改ざん防止構造はこのような不自然な形状変形を痕跡に不適切な容器の開封を見つけ出すことを可能としている。 Once the folded end portion 65 of the second flange portion 60 is in a yielding state, the original state (see FIG. 8) cannot be restored, and thus the trace of unauthorized opening cannot be hidden. Therefore, if the structure around the second flange portion 60 of the second container 50 in the state shown in the figure is confirmed, it can be easily confirmed whether or not the unauthorized opening has been performed. The tamper-proof structure according to the present invention makes it possible to find an inappropriate container opening by using such unnatural shape deformation as a trace.

図１２は第２実施例の改ざん防止容器２の組み合わせ前の改ざん防止容器２の上方から見た平面図であり、第１容体１０ｘについては容器本体Ｃの内面側が示され、第２容体５０ｘについては蓋体Ｔの外面側が示される。第１実施例の改ざん防止容器１（図２参照）と同様に、第１容体１０ｘでも開口部１１の全周囲１２に当該容体の容器本体部１３の外方へ延設した第１フランジ部２０ｘが備えられる。第２容体５０ｘでも開口部５１の全周囲５２に当該容体の容器本体部５３の外方へ延設した第２フランジ部６０ｘが備えられる。第１容体１０の平板部１４は容器本体Ｃにおける底部となる。第２容体５０の平板部５４は蓋体Ｔにおける天板となる。 FIG. 12 is a plan view of the anti-tamper container 2 before the combination of the anti-tamper container 2 of the second embodiment as viewed from above, and the inner surface side of the container body C is shown for the first container 10x, and the second container 50x is shown. Indicates the outer surface side of the lid T. Similar to the tamper-proof container 1 of the first embodiment (see FIG. 2), the first flange portion 10x of the first container 10x extends outward from the container body 13 of the container around the entire periphery 12 of the opening 11. Is provided. The second container 50x is also provided with a second flange portion 60x that extends outward from the container body 53 of the container around the entire periphery 52 of the opening 51. The flat plate portion 14 of the first container 10 is a bottom portion of the container main body C. The flat plate portion 54 of the second container 50 is a top plate in the lid T.

改ざん防止容器２の特徴として、第１容体１０ｘの開口部１１及び第２容体５０ｘはともに平面視多角形状に形成されている。図示では面取りされた四角形（長方形）である。併せて、図示のとおり、第２フランジ部６０ｘに易破壊部７０が設けられる。易破壊部の構造は前述のとおりであるため説明を省略する。この例の易破壊部７０は、第２フランジ部６０ｘの全周ではなく、容体の２辺に設けられている。 As a feature of the falsification preventing container 2, the opening 11 and the second container 50x of the first container 10x are both formed in a polygonal shape in plan view. In the figure, it is a chamfered rectangle (rectangle). In addition, as shown in the figure, the easily breakable portion 70 is provided in the second flange portion 60x. Since the structure of the easily breakable portion is as described above, the description thereof is omitted. The easily breakable portion 70 in this example is provided not on the entire circumference of the second flange portion 60x but on two sides of the container.

改ざん防止容器２の例示のとおり、改ざん防止構造Ｓｒを適用できる容器形状は比較的自由である。改ざん防止構造自体は図示以外の多角形をはじめ、楕円や星形等の適宜の形状にも適用可能である。すなわち、包装対象に応じた自由な容器設計が可能となり、同時に、それらの容器であっても改ざん防止機能が有効に発揮される。また、易破壊部は、容器開封の必要時に第２フランジ部の破壊を促進できて第２容体の取り外しが円滑にできれば良い。そのため、容器自体の形状を考慮して必要箇所のみに易破壊部は形成される。 As illustrated in the anti-falsification container 2, the container shape to which the anti-falsification structure Sr can be applied is relatively free. The tamper-proof structure itself can be applied to polygons other than those shown in the drawings, as well as appropriate shapes such as ellipses and stars. In other words, it is possible to design a free container according to the packaging object, and at the same time, the function of preventing falsification is effectively exhibited even with these containers. Moreover, the easy-to-break part should just accelerate | stimulate destruction of a 2nd flange part at the time of a container opening necessity, and can remove the 2nd container smoothly. Therefore, the easily destructible portion is formed only at a necessary portion in consideration of the shape of the container itself.

図１３は第３実施例の改ざん防止容器３の全体縦断面図であり、容器本体Ｃの第２容体５０ｙに蓋体Ｔの第１容体１０ｙを重ねた状態であり、第２容体５０ｙによる内嵌合の形態である。第１容体１０ｙの第１フランジ部２０ｙは、第２容体５０ｙの第２フランジ部６０ｙに対して合着される。改ざん防止容器３のように、容器本体Ｃの側に改ざん防止構造Ｓｒの主要部分を備えることもできる。従って、当該改ざん防止構造は容器本体または蓋体のいずれにも自在に配置でき、容器の形状とともに上下の選択も自由となる。そうすると、容器の包装対象に応じた容器形状の選択の幅が広がり、容器を使用する事業者の要望に応えやすくなる。同時に、視覚的な印象を高める形状とすることもでき、購買者への訴求効果を高めることもできる。 FIG. 13 is an overall vertical cross-sectional view of the tamper-proof container 3 of the third embodiment, in which the first container 10y of the lid T is overlaid on the second container 50y of the container main body C, and the inside of the second container 50y It is a form of fitting. The first flange portion 20y of the first container 10y is joined to the second flange portion 60y of the second container 50y. Like the falsification preventing container 3, the main part of the falsification preventing structure Sr can be provided on the container main body C side. Therefore, the tamper-proof structure can be freely arranged on either the container main body or the lid, and the upper and lower options can be freely selected together with the shape of the container. If it does so, the range of selection of the container shape according to the packaging object of a container will spread, and it will become easy to respond to the request | requirement of the provider who uses a container. At the same time, it can be shaped to enhance the visual impression, and the appeal effect to the buyer can be enhanced.

図１４は第４実施例の改ざん防止容器４の主要部分断面図であり、最も単純な改ざん防止構造Ｓｒ’の例である。第１容体１０ｚの開口部１１の全周囲１２に容器本体部１３の外方へ延設した第１フランジ部２０ｚが備えられる。また、第２容体５０ｚの開口部５１の全周囲５２にも容器本体部５３の外方へ延設した第２フランジ部６０ｚが備えられる。この例の第１フランジ部２０ｚは平板状のみである。第２フランジ部６０ｚもフランジ本体部６２と、同フランジ本体部６２と直交し第１容体１０ｚ側に伸長する被覆周壁部６３が備えられる。そして、被覆周壁部６３の伸長した末端となる端部６４には、被覆周壁部６３の伸長方向と逆に第２容体５０ｚ側に折り返された折り返し端部６５が直に備えられる。 FIG. 14 is a main part sectional view of the tamper-proof container 4 of the fourth embodiment, which is an example of the simplest tamper-proof structure Sr ′. A first flange portion 20z extending outward from the container main body 13 is provided around the entire periphery 12 of the opening 11 of the first container 10z. A second flange portion 60z extending outward from the container main body 53 is also provided on the entire periphery 52 of the opening 51 of the second container 50z. The first flange portion 20z in this example is only flat. The second flange portion 60z is also provided with a flange body portion 62 and a covering peripheral wall portion 63 that is orthogonal to the flange body portion 62 and extends toward the first container 10z. Then, the end 64 that is the extended end of the covering peripheral wall 63 is directly provided with a folded end 65 that is folded back toward the second container 50z in the direction opposite to the extending direction of the covering peripheral wall 63.

第１容体１０ｚと第２容体５０ｚの合着時、第１容体１０ｚの第１フランジ部２０のフランジ端部２１は、フランジ本体部６２と被覆周壁部６３の折れ曲がり構造により覆われる。さらに、フランジ端部２１に設けられた曲げ縁部２２に対しても被覆周壁部６３は横から被さる。そして、折り返し端部６５は第１フランジ部２０の背面部２３と係合可能となる。このように、改ざん防止構造Ｓｒ’も同様に、第２容体５０ｚの第２フランジ部６０ｚ（被覆周壁部６３、折り返し端部６５）が第１容体１０ｚの第１フランジ部２０ｚを巻き込むようにして被さる。従って、いったん容体同士が嵌合した後、容体同士は容易に外れなくなる。 At the time of joining the first container 10z and the second container 50z, the flange end portion 21 of the first flange portion 20 of the first container 10z is covered by the bent structure of the flange main body portion 62 and the covering peripheral wall portion 63. Further, the covering peripheral wall 63 covers the bent edge 22 provided at the flange end 21 from the side. The folded end portion 65 can be engaged with the back surface portion 23 of the first flange portion 20. In this way, the tamper-proof structure Sr ′ is similarly configured so that the second flange portion 60z (the covering peripheral wall portion 63 and the folded end portion 65) of the second container 50z winds around the first flange portion 20z of the first container 10z. Put on. Therefore, once the containers are fitted together, the containers cannot be easily detached.
