Description

本考案は、容器本体と蓋体とが合成樹脂フイルム素材で成形される食品用容器に関し、さらに詳細には、小形の生鮮食品や果物を収納して陳列販売するのに適した使い捨てタイプの軽量の食品用容器に関する。 The present invention relates to a food container in which a container body and a lid are formed of a synthetic resin film material. More specifically, the present invention is a disposable lightweight suitable for storing and selling small fresh food and fruits. This relates to a food container.

従来から、合成樹脂フイルム素材で形成された容器であって、容器本体と蓋体とが形成される軽量の食品用容器は、使い捨てタイプの食品用容器として、種々の食品の包装用に製造されており、収納する食品の種類に応じて様々な工夫がなされて提供されている。 Conventionally, a lightweight food container, which is a container made of a synthetic resin film material and in which a container body and a lid are formed, is manufactured as a disposable food container for packaging various foods. It has been devised in various ways depending on the type of food to be stored.

このような食品用容器の一つに、生鮮食品や果物等の鮮度が要求される食品を収納するためのものがあるが、これら食品の鮮度を保つために、蓋体の天板部分（天井壁）に空気流通用の小孔を形成したものが利用されている（特許文献１参照）。 One of these food containers is for storing foods that require freshness such as fresh foods and fruits. To maintain the freshness of these foods, the top plate of the lid (ceiling) A wall is formed with small holes for air circulation (see Patent Document 1).

また、店頭販売される生鮮食品は多様化しており、その食品に応じて、顧客が購買しやすい適量を、個々の容器に収納して販売する必要がある。そのため、容器の大きさや形状を、食品の販売単位に合わせて作るようにしている。
特許第３３６４８００号公報 In addition, fresh foods sold in stores are diversified, and it is necessary to store and sell appropriate amounts that are easy for customers to purchase according to the foods in individual containers. Therefore, the size and shape of the container are made to match the sales unit of food.
Japanese Patent No. 3364800

最近は、ブルーベリー、ミニトマト等のような小形の生鮮食品や果物を少量ずつ収納して陳列販売するものが多い。この場合、食品用容器自体も小型になるので、生鮮食品を容器内に収納した同形状の食品用容器を、数層に積み重ねて陳列し、店頭販売されるのが一般的である。したがって、容器どうしを安定して積層できるようにすることが必要であるとともに、積層された状態でも収納物の鮮度を維持できる容器が必要となる。ところが、上述した文献にあるような天板部分（天井壁）に空気流通用の小孔を形成した容器では、積層した状態にすると、小孔の上に他の容器が積み重ねられているので、空気の流通を十分に行うことが困難であった。 Recently, many small fresh foods such as blueberries and cherry tomatoes are stored and sold in small quantities. In this case, since the food container itself is also reduced in size, it is common that food containers of the same shape containing fresh food in the container are stacked and displayed in several layers and sold over the counter. Therefore, it is necessary to make it possible to stably stack containers, and a container that can maintain the freshness of stored items even in a stacked state. However, in a container in which small holes for air circulation are formed in the top plate part (ceiling wall) as described in the above-mentioned literature, when stacked, other containers are stacked on the small holes. It was difficult to sufficiently distribute air.

また、使い捨てタイプの合成樹脂フイルム素材で形成された軽量の食品用容器にあっては、材料コストの面から０．２〜０．６ｍｍ程度の薄さのもの、厚いものでも０．８ｍｍ程度までの薄い素材で製造される。そのため、積み重ねられた状態で下側になり、その上側に載置される容器の荷重が加わることになっても、容器が押しつぶされることなく十分に耐えるようにすることも必要である。 For lightweight food containers made of disposable synthetic resin film materials, the thickness is about 0.2 to 0.6 mm from the viewpoint of material cost, and even thick ones are about 0.8 mm. Made of thin material. For this reason, even when a load is applied to a container placed on the lower side in the stacked state and placed on the upper side, it is necessary to sufficiently withstand the container without being crushed.

そこで、本考案は、複数の容器が積層状態で陳列されるときにも、鮮度を維持することができる食品用容器を提供することを目的とする。
さらに、本考案は鮮度を維持できるとともに、積層状態でも荷重に耐えうる食品用容器を提供することを目的とする。 Therefore, an object of the present invention is to provide a food container capable of maintaining freshness even when a plurality of containers are displayed in a stacked state.
Furthermore, an object of the present invention is to provide a food container that can maintain freshness and can withstand a load even in a laminated state.

The bottom wall 11 is formed to have a size that can be placed on the ceiling wall 21 inside the stepped portion 22, and the main body side wall 12 has recesses that cross the main body side wall 12. A plurality of vertical ribs 15 are formed, and air holes A are formed in the main body side wall 12 between the vertical ribs 15.

また、第六の考案は、上記考案において、本体側壁１２および蓋体側壁２３は傾斜面からなり、斜面上に空気孔Ａが形成される構成としたものである。 In addition, the sixth device is configured such that, in the above device, the main body side wall 12 and the lid side wall 23 are inclined surfaces, and the air holes A are formed on the inclined surfaces.

第一の考案によれば、閉蓋状態で水平面となる蓋体２の天井壁２１の上に、水平面を有する容器本体１の底壁１１を載置するようにして、複数の食品用容器を積層する。容器どうしは、安定して積み重ねることができ、本体側壁１２および蓋体側壁２３に空気孔Ａが形成されているので、下側容器の天井壁２１に上側容器の底壁１１が重なるように積層した状態でも、本体側壁１２および蓋体側壁２３に設けられた空気孔Ａは閉塞されることがなくなり、容器内を十分に通気させることができて食品の鮮度を保つことが可能となる。 According to the first device, the bottom wall 11 of the container body 1 having a horizontal surface is placed on the ceiling wall 21 of the lid body 2 that becomes a horizontal surface in the closed state, so that a plurality of food containers are disposed. Laminate. The containers can be stably stacked, and air holes A are formed in the main body side wall 12 and the lid side wall 23, so that the bottom wall 11 of the upper container overlaps the ceiling wall 21 of the lower container. Even in this state, the air hole A provided in the main body side wall 12 and the lid side wall 23 is not blocked, and the inside of the container can be sufficiently ventilated to maintain the freshness of the food.

第二の考案によれば、蓋体側壁２３に空気孔Ａが形成され、容器本体１には空気孔が形成されない構成としたので、水分等が発生しやすい食品を収納する場合であっても、空気孔Ａから液体がこぼれ落ちにくくなり、それでいて通気性を蓋体側壁２３の空気孔Ａで確保できるので、鮮度を維持できる。 According to the second device, since the air hole A is formed in the lid side wall 23 and the air hole is not formed in the container body 1, even when food that easily generates moisture or the like is stored. Since the liquid is less likely to spill from the air hole A, and the air permeability can be ensured by the air hole A in the lid side wall 23, freshness can be maintained.

第三の考案によれば、本体側壁１２に空気孔Ａが形成され、蓋体２には空気孔が形成されない構成としたので、上から雨水や水滴等が落下しても、水滴等が内部に浸入しにくくなり、それでいて通気性を容器本体１の空気孔Ａで確保できるので、鮮度を維持できる。 According to the third device, since the air hole A is formed in the main body side wall 12 and the air hole is not formed in the lid body 2, even if rain water or water drops fall from above, The air permeability of the container body 1 can be ensured by the air hole A of the container body 1, so that the freshness can be maintained.

第四の考案によれば、容器本体１側の水平段部１５と蓋体２側の水平鍔部２４とが面接するようにしてあり、これらにより積層時の耐荷重性を強化できる。また、底壁１１は段部２２内側の天井壁２１に載置可能な大きさに形成されているので、積層するときに下側容器の天井壁２１上に、上側容器の底壁１１を積み重ねることができ、これにより、上下方向に整列して積層させることができるので、本体側壁１２または蓋体側壁２３の少なくともいずれかに設けた空気孔Ａは、他の容器によって閉塞されることを完全に防ぐことができる。 According to the fourth device, the horizontal step portion 15 on the container body 1 side and the horizontal flange portion 24 on the lid 2 side are in contact with each other, and the load resistance at the time of stacking can be enhanced. Moreover, since the bottom wall 11 is formed in a size that can be placed on the ceiling wall 21 inside the step portion 22, the bottom wall 11 of the upper container is stacked on the ceiling wall 21 of the lower container when stacked. In this way, the air holes A provided in at least one of the main body side wall 12 and the lid side wall 23 can be completely blocked by other containers. Can be prevented.

第五の考案によれば、本体側壁１２を横断する凹部が並んだ縦リブ１５が形成されるとともに、縦リブ１５の間の本体側壁１２に空気孔Ａが形成される構成としたので、耐荷重性を強化することができる。特に、縦リブ１５の間に空気孔Ａが形成される構成としたので、空気孔Ａを形成したことによる強度の劣化分を、縦リブ１５により補うことができる。 According to the fifth aspect, the vertical ribs 15 in which the recesses crossing the main body side wall 12 are arranged and the air holes A are formed in the main body side walls 12 between the vertical ribs 15. Loadability can be strengthened. In particular, since the air holes A are formed between the longitudinal ribs 15, the strength deterioration due to the formation of the air holes A can be compensated by the longitudinal ribs 15.

第六の考案によれば、上記考案において、本体側壁１２および蓋体側壁２３は傾斜面とし、傾斜面に空気孔Ａが形成されるようにしたので、空気孔Ａの上または下に空間が確保され、さらに容器を上下方向に積層するだけでなく、横方向に密着させて陳列させた場合にも空気流通性を向上させることができる。 According to the sixth device, in the above device, the main body side wall 12 and the lid side wall 23 are inclined surfaces, and the air holes A are formed in the inclined surfaces, so that there is a space above or below the air holes A. In addition, the air flowability can be improved not only when the containers are stacked in the vertical direction but also when they are displayed in close contact in the horizontal direction.

以下、本考案の構成を、図面を用いて説明する。ここでは、ブルーベリーを収納するための容器を例にして説明する。図１は、本考案の一実施形態である食品用容器の構成を示す平面図、図２はその正面図である。 The configuration of the present invention will be described below with reference to the drawings. Here, a container for storing blueberries will be described as an example. FIG. 1 is a plan view showing a configuration of a food container according to an embodiment of the present invention, and FIG. 2 is a front view thereof.

本容器１０は、容器本体１と、蓋体２と、容器本体１と蓋体２とを接続するヒンジ部３とが一体に形成される。
容器１０の大きさは、四隅を円弧状とした約１００ｍｍ四方の正方形状とされ、容器本体１の深さを約２０ｍｍ、蓋体２の上下深さを約１０ｍｍとした大きさの容器であって、０．３〜０．４ｍｍの薄いＰＥＴ樹脂フイルム材によって形成してある。 In the present container 10, a container body 1, a lid body 2, and a hinge portion 3 that connects the container body 1 and the lid body 2 are integrally formed.
The size of the container 10 is a container having a size of about 100 mm square with four corners being arc-shaped, the depth of the container body 1 is about 20 mm, and the upper and lower depth of the lid 2 is about 10 mm. The thin PET resin film material of 0.3 to 0.4 mm is formed.

本考案の容器を形成するに当たっては、従来から知られているブロー成型手段によって所定の形状を付与する。合成樹脂シートはこの様な容器に対して従来から用いられているシート材であればいかなる種類のものでも使用できるが、合成樹脂シート素材としてＰＥＴ（ポリエチレンテレフタレート）樹脂を使用すると廃材リサイクルが可能であり、また、焼却処理する場合でも発熱量が少ないので、焼却炉の寿命を縮めることなく、かつ、ダイオキシン等の有害物質の生成を排除でき公害問題解決に対処し得る利点がある。また、ＰＥＴ樹脂に代えて、生分解性プラスチック樹脂材を用いれば、廃棄処理が容易であり環境にやさしい容器とすることもできる。 In forming the container of the present invention, a predetermined shape is imparted by a conventionally known blow molding means. Any kind of synthetic resin sheet can be used as long as it is a conventional sheet material for such a container, but if PET (polyethylene terephthalate) resin is used as the synthetic resin sheet material, waste material can be recycled. In addition, since the calorific value is small even when incineration is performed, there is an advantage that the generation of harmful substances such as dioxin can be eliminated and the problem of pollution can be addressed without shortening the life of the incinerator. If a biodegradable plastic resin material is used instead of the PET resin, the container can be easily disposed of and is environmentally friendly.

容器本体１は、約７０ｍｍ四方の水平面を有する底壁１１と、底壁１１の周縁から外側上方に向けて延設される本体側壁１２とにより食品収納空間が形成される。本体側壁１２をより詳しく説明すると、傾斜面からなる下部側壁１２ａと下部側壁１２aより急斜面に形成された上部側壁１２ｂとの二段斜面構造にしてある。本体側壁１２（上部側壁１２ｂ）の上端は、容器本体１の上部開口を形成する。上部開口周縁には、外周方向に向かって延設された約３ｍｍ幅の水平段部１５と、水平段部１５の周縁から垂下された約４ｍｍ幅の垂下壁１６と、垂下壁１６の下端から更に外周方向に向かって延設された約３ｍｍ幅の本体フランジ部１３とを備えている。垂下壁１６の四隅部分には、上下方向幅の上半部に配置されて外周方向に向かってわずかに突出する外向き突出部１７が形成され、後述する蓋体２の対応部分と面接すると、蓋体２が閉じた状態で保持できるようにしてある。 In the container main body 1, a food storage space is formed by a bottom wall 11 having a horizontal surface of about 70 mm square and a main body side wall 12 extending outward from the periphery of the bottom wall 11. The main body side wall 12 will be described in more detail. The main body side wall 12 has a two-step slope structure having a lower side wall 12a formed of an inclined surface and an upper side wall 12b formed on a steep slope from the lower side wall 12a. The upper end of the main body side wall 12 (upper side wall 12b) forms an upper opening of the container main body 1. At the periphery of the upper opening, a horizontal step portion 15 having a width of about 3 mm extending toward the outer peripheral direction, a hanging wall 16 having a width of about 4 mm hanging from the periphery of the horizontal step portion 15, and a lower end of the hanging wall 16 Furthermore, the main body flange part 13 of about 3 mm width extended toward the outer peripheral direction is provided. At the four corners of the hanging wall 16 are formed outward projecting portions 17 that are arranged in the upper half of the vertical width and slightly project in the outer peripheral direction. The lid 2 can be held in a closed state.

また、容器本体１の四つの辺には、それぞれ上下方向に向けて凹部が形成された半円弧状の縦リブ１８が形成してあり、これら縦リブ１８を形成することによって、外観上の変化を与えるとともに耐圧変形強度の強化を図っている。なお、縦リブ１８の形状は半円弧状に限られず、他の形状であってもよい。また縦リブ１８の本数は容器の大きさに応じて増減するようにしてもよい。 Further, on the four sides of the container body 1, semicircular arc-shaped vertical ribs 18 each having a concave portion formed in the vertical direction are formed. In addition, the pressure deformation strength is strengthened. In addition, the shape of the vertical rib 18 is not limited to a semicircular arc shape, and may be another shape. Further, the number of the vertical ribs 18 may be increased or decreased according to the size of the container.

隣り合う２つの縦リブ１８の間の本体側壁１２（下部側壁１２a）には、長円形状の空気孔Ａが形成されている。さらに本体側壁１２の四隅の位置にも空気孔Ａが形成されている。空気孔Ａの大きさは収納される食品が孔から飛び出ない程度にしてある。 An oval air hole A is formed in the main body side wall 12 (lower side wall 12 a) between two adjacent vertical ribs 18. Further, air holes A are also formed at the four corner positions of the main body side wall 12. The size of the air hole A is set so that the food to be stored does not jump out of the hole.

蓋体２は、容器本体１を閉蓋状態にしたときに水平面となる約７５ｍｍ四方の天井壁２１を有する。天井壁２１の周縁には、外側上方に向けて約２ｍｍ程度立ち上がる段部２２が形成され、段部２２の外周縁は外側下方に向けて傾斜面となる蓋体側壁２３が形成される。蓋体側壁２３をより詳しく説明すると、段部２２からの連続曲面が傾斜面となっている上部側壁２３ａと、上部側壁２３ａよりも緩やかな平面状斜面からなる約２ｍｍ幅の下部側壁２３ｂとの二段斜面構造にしてある。 The lid body 2 has a ceiling wall 21 of about 75 mm square that becomes a horizontal plane when the container body 1 is closed. A step portion 22 is formed on the periphery of the ceiling wall 21 so as to rise about 2 mm outward and upward, and an outer periphery of the step portion 22 is formed with a lid side wall 23 that becomes an inclined surface downward and outward. The lid side wall 23 will be described in more detail. An upper side wall 23a having a continuous curved surface from the step portion 22 is an inclined surface, and a lower side wall 23b having a plane slope that is gentler than the upper side wall 23a. It has a two-step slope structure.

蓋体側壁２３（詳しくは下部側壁２３ｂ）の外周縁には、容器本体１の水平段部１５と面接する約３ｍｍ幅の水平鍔部２４が形成される。水平鍔部２４の外周縁には、容器本体１の垂下壁１６に外接する約５ｍｍ幅の縦壁２５と、縦壁２５の下端から更に外周方向に向かって延設された約３ｍｍ幅の蓋体フランジ部２６とを備えている。 On the outer peripheral edge of the lid side wall 23 (specifically, the lower side wall 23b), a horizontal flange 24 having a width of about 3 mm is formed so as to be in contact with the horizontal step portion 15 of the container body 1. On the outer peripheral edge of the horizontal flange 24, there are a vertical wall 25 having a width of about 5 mm circumscribing the hanging wall 16 of the container body 1, and a lid having a width of about 3 mm extending from the lower end of the vertical wall 25 toward the outer periphery. And a body flange portion 26.

縦壁２５の四隅部分には、上下方向幅の下半部に配置されて内周方向に向かって突出し、容器本体１における外向き突出部１７と上下方向において係合する位置関係に形成された内向き突出部２７が形成されている。既述のように、閉蓋状態で、外向き突出部１７と内向き突出部２７とが面接して係合することにより蓋体２が閉じた状態で保持できるようにしてある。 At the four corners of the vertical wall 25, it is arranged in the lower half of the vertical width and protrudes toward the inner circumferential direction, and is formed in a positional relationship that engages with the outward protruding portion 17 in the container body 1 in the vertical direction. An inward protruding portion 27 is formed. As described above, in the closed state, the outward projecting portion 17 and the inward projecting portion 27 are brought into contact with each other so that the lid body 2 can be held in a closed state.

蓋体２の蓋体側壁２３（２３ａ，２３ｂ）には、四隅および四辺上において、それぞれ蓋体側壁２３の傾斜面を上下方向に横断するように、長円形状の空気孔Ａが間隔を開けて複数個形成されている。一部の空気孔Ａは、孔面積を広げるために、空気孔Ａの下端が水平鍔部２４に達するようにしてある。 In the lid side wall 23 (23a, 23b) of the lid body 2, oval air holes A are spaced apart at the four corners and the four sides so as to cross the inclined surface of the lid side wall 23 in the vertical direction. Are formed. Some of the air holes A are configured such that the lower end of the air hole A reaches the horizontal flange 24 in order to increase the hole area.

容器本体１と蓋体２とを接続するヒンジ部３は、容器本体１および蓋体２とともに一体形成され、ヒンジ部３で折り曲げることにより、蓋体２の蓋体フランジ部２６と容器本体１の本体フランジ部１３とが面接するようにしてある。 The hinge portion 3 that connects the container body 1 and the lid body 2 is integrally formed with the container body 1 and the lid body 2, and is bent at the hinge portion 3, whereby the lid flange portion 26 of the lid body 2 and the container body 1. The main body flange portion 13 is in contact with the main body flange portion 13.

このような構造とされた食品用容器１０は、容器本体１内にブルーベリーを所要量分入れて、上方から蓋体２を容器本体１に載せて軽く押し付ければ蓋体２が嵌合され、閉蓋状態にすることができる。閉蓋状態にしても、容器本体１や蓋体２に形成された空気孔Ａを介して内部を通気することができることから、ブルーベリーの鮮度の維持が容易である。 In the food container 10 having such a structure, a required amount of blueberries is put into the container body 1, and the lid body 2 is put on the container body 1 from above and lightly pressed to fit the lid body 2. The lid can be closed. Even in the closed state, the inside can be ventilated through the air holes A formed in the container main body 1 and the lid 2, so that it is easy to maintain the freshness of blueberries.

また、食品用容器１０は、店頭販売時に、数段程度は同型の容器どうしを積層する。すなわち、下側に配置される食品用容器１０の天井壁２１の上に、上側に配置される食品容器１０の底壁１１が載置されるようにして、次々と積層する。このとき、下側容器の天井壁２１の段部２２により、上側容器の底壁１１の載置位置が案内される。底壁１２と天井壁２１とは、面どうしが接触することになるが、本体側壁１２や蓋体側壁２３は、積層された状態でどこにも当接しない。したがって、本体側壁１２や蓋体２３に形成された空気孔Ａは、他の容器と接触して閉塞されることはないので、空気孔Ａにより空気流通性を確保できる。 In addition, the food containers 10 are laminated at the same time in several stages at the time of over-the-counter sales. In other words, the bottom wall 11 of the food container 10 disposed on the upper side is placed on the ceiling wall 21 of the food container 10 disposed on the lower side, and then stacked one after another. At this time, the mounting position of the bottom wall 11 of the upper container is guided by the step 22 of the ceiling wall 21 of the lower container. The bottom wall 12 and the ceiling wall 21 come into contact with each other, but the main body side wall 12 and the lid side wall 23 are not in contact with each other in a stacked state. Therefore, the air holes A formed in the main body side wall 12 and the lid body 23 are not blocked by contact with other containers, and therefore air circulation can be ensured by the air holes A.

容器どうしを積層することにより、下側の容器には、上側容器の荷重が付加されるが、水平段部１５や水平鍔部２４を設けたり、あるいは、容器本体１に縦リブが設けたりすることにより、耐荷重性を増すようにすることができる。 By laminating the containers, the load of the upper container is applied to the lower container, but the horizontal step portion 15 and the horizontal flange portion 24 are provided, or the main rib 1 is provided with the vertical rib. As a result, the load resistance can be increased.

図３は、本考案の他の一実施形態である食品用容器の構成を示す平面図、図４はその正面図である。図において、図１、図２と同じものは同符号を付すことにより、説明を省略する。本実施形態では、容器本体１には空気孔Ａを設けておらず、蓋体２についてのみ空気孔Ａを形成するようにしている。
このように、容器本体１側に空気孔Ａを形成しないようにすることにより、水分等が発生しやすい食品を収納する場合であっても、容器本体１には空気孔がないので、空気孔Ａから液体がこぼれ落にくくなり、それでいて通気性を蓋体２の空気孔Ａで確保できるので、鮮度を維持できる。 FIG. 3 is a plan view showing a configuration of a food container according to another embodiment of the present invention, and FIG. 4 is a front view thereof. In the figure, the same components as those in FIG. 1 and FIG. In the present embodiment, the air hole A is not provided in the container body 1, and the air hole A is formed only for the lid 2.
In this way, by not forming the air holes A on the container body 1 side, the container body 1 has no air holes even when storing foods that easily generate moisture or the like. Since the liquid is less likely to spill from A and air permeability can be ensured by the air hole A of the lid 2, freshness can be maintained.

図５は、さらに本考案の他の一実施形態である食品用容器の構成を示す平面図、図６はその正面図である。図において、図１、図２と同じものは同符号を付すことにより、説明を省略する。本実施形態では、蓋体２には空気孔Ａを設けておらず、容器本体１についてのみ空気孔Ａを形成するようにしている。
このように、蓋体２に空気孔Ａを形成しないようにすることにより、上から雨水や水滴等が落下しても、水滴等が内部に浸入しにくくなり、それでいて通気性を容器本体１の空気孔Ａで確保できるので、鮮度を維持できる。 FIG. 5 is a plan view showing the configuration of a food container according to another embodiment of the present invention, and FIG. 6 is a front view thereof. In the figure, the same components as those in FIG. 1 and FIG. In the present embodiment, the air hole A is not provided in the lid 2, and the air hole A is formed only for the container body 1.
In this way, by not forming the air hole A in the lid 2, even if rainwater or water droplets fall from above, water droplets or the like are less likely to enter the interior, and yet the air permeability of the container body 1 is reduced. Since it can be secured by the air hole A, the freshness can be maintained.

なお、上述した実施形態では、いずれも容器本体１と蓋体２とをヒンジ部３で接続し一体形成するようにしたが、容器本体１と蓋体２とを別々に形成してもよい。 In each of the above-described embodiments, the container body 1 and the lid body 2 are connected by the hinge portion 3 and integrally formed. However, the container body 1 and the lid body 2 may be formed separately.
