しかしながら、このような構成のコンテナでは、２つの側壁同士または端壁自体が切り離されて形成されており、２つの側壁同士の突き合せ部分または端壁自体の内部につなぎ目が形成される。つなぎ目では、密封性が損なわれやすく、内部に収納する物品が劣化しやすくなる虞がある。また、つなぎ目は、十分な強度を得られない可能性があり、内部に収納する物品の保護が不十分になる虞もある。 However, in such a container, the two sidewalls or the end wall itself are formed separately and the seam is formed at the abutment of the two sidewalls or within the end wall itself. At the seams, the sealability is likely to be impaired, and there is a risk that the articles stored inside are likely to deteriorate. In addition, there is a possibility that sufficient strength cannot be obtained from the seam, and there is also a possibility that the protection of the articles stored inside may be insufficient.

本発明は、三角プリズム形状の収納物を収納することが可能であり、収納物を保護しつつ気密性を高めることができる容器を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a container capable of storing a triangular prism-shaped stored item and capable of improving airtightness while protecting the stored item.

The container has a first side, a second side and a pair of sides. The first surface portion has a quadrangular shape including a pair of side sides of the same length that are arranged to face each other. The second surface portion has a quadrangular shape including a pair of side sides of the same length that are arranged to face each other, and is directly or indirectly connected to one side of the first surface portion other than the side sides. It is arranged at a predetermined angle with respect to the first surface. The pair of side surface portions includes a first side indirectly connected to the side edge of the first surface portion and a second side connected directly or indirectly to the side edge of the second surface portion. and The housing portion is formed by the first surface portion, the second surface portion, and the pair of side surface portions, and has a triangular prism shape having an opening in a portion facing the first surface portion and the second surface portion. The sheet member includes the first surface portion, the second surface portion, the pair of side surface portions, a plurality of folded portions, a first projecting portion, a second projecting portion, and a third projecting portion. Prepare. The side edge and the first edge of the first surface portion are indirectly connected via the folded portion. The side edge and the second side of the second surface portion indirectly connected to the pair of side surface portions are indirectly connected via the folded portion. The first protruding portion is directly connected to a side of the first surface portion opposite to a side connected to the second surface portion. The second protruding portion is directly connected to a third side adjacent to the first side and the second side of the side portion. The third protruding portion is directly connected to a side of the second surface portion opposite to a side connected to the first surface portion. An end portion of the second projecting portion on a side close to the folded portion includes a projecting portion that projects outward from the end portion of the third side. The folded portion is folded in half along a folding line extending from the inner end of the first side or the second side of the side portion to the outer edge and is adhered to the outer surface of the side portion.

このように構成することで、折り返し部が、側面部の外側に接着される。折り返し部で折り返して三角形プリズム形状に形成するため、外力により容器がつぶれにくく、収納物を保護することができる。また、折り返し部を側面部に接着して三角プリズム形状に形成した状態で、上下に重ねて配置する場合でも、重ねた容器によって折り返し部が押されて剥がれにくい。そのため、作成した容器を重ねて保管、持ち運びすることができるので使用しやすい。また、つなぎ目がないことで、気密性を高めることも可能である。 With this configuration, the folded portion is adhered to the outside of the side portion. Since the container is folded back at the folded portion to form a triangular prism shape, the container is less likely to be crushed by an external force, and the stored items can be protected. In addition, even when the folded portions are adhered to the side portions to form a triangular prism shape and are stacked one on top of the other, the folded portions are pressed by the stacked containers and are less likely to come off. Therefore, it is easy to use because the created containers can be stacked and stored and carried. In addition, since there is no seam, airtightness can be improved.

上記構成において、一枚の紙シートから構成され、前記紙シートの収納物を収納する側の面に耐油性層および耐水性層の少なくとも一方が積層されていてもよい。このように構成することで、内部に、水、油等が含まれる収納物を収納することが可能である。また、これ以外にも、水、油等が外部に漏れるのを防いだり、外部からのガスを防いだりすることができる層を備えていてもよい。 In the above structure, it may be composed of a single paper sheet, and at least one of an oil-resistant layer and a water-resistant layer may be laminated on the surface of the paper sheet on the side of the paper sheet on which the stored items are to be stored. By configuring in this way, it is possible to store items containing water, oil, etc. inside. In addition to this, a layer capable of preventing leakage of water, oil, etc. to the outside or preventing gas from the outside may be provided.

上記構成において、前記第１面部と前記第２面部とは直接連設されていてもよい。このように構成することで、容器を形成するシートの形状を簡略化することができる。これにより製造にかかる手間と時間を省くことが可能である。また、一枚の紙シートで構成するため、つなぎ目がなく、容器の強度を高めることが可能である。これにより、収納物を保護することが可能である。 The said structure WHEREIN: A said 1st surface part and a said 2nd surface part may be directly connected. By configuring in this way, the shape of the sheet forming the container can be simplified. This can save labor and time required for manufacturing. Moreover, since it is composed of a single sheet of paper, there is no seam, and the strength of the container can be increased. This makes it possible to protect the stored items.

上記構成において、長方形状の第３面部をさらに備え、前記第３面部の二対の対向する辺のうち一方の対向する辺のそれぞれに前記第１面部と、前記第２面部とが直接的に連設されており、前記第３面部の他方の対向する辺のそれぞれに一対の前記側面部が直接的に連接されていてもよい。このようすることで、開口を下にして置いたときに、上部に平面部が形成される。これにより、容器を重ねたときに安定しやすい。 In the above configuration, a rectangular third surface portion is further provided, and the first surface portion and the second surface portion are directly connected to one of two pairs of opposing sides of the third surface portion, respectively. The pair of side surface portions may be directly connected to each of the other opposing sides of the third surface portion. By doing so, a flat portion is formed on the upper portion when the opening is placed downward. This makes it easy to stabilize the containers when stacked.

上記構成において、前記第２面部と前記側面部の第２辺とは、前記折り返し部を介して間接的に連設され、前記第１張出部、前記第２張出部および前記第３張出部は、それぞれ、前記収納部に対して外側に折り曲げられており、前記第１張出部、前記第２張出部および前記第３張出部に接着される蓋部をさらに備える。これにより、第１張出部と第２張出部とを外側に折り曲げたとき、第１張出部の両端と第２張出部の突出部との間に、Ｖ字状の切欠きが形成されにくい。これにより、フランジ部で熱接着したときの気密性を保つことが可能である。 In the above configuration, the second surface portion and the second side of the side surface portion are indirectly connected to each other via the folded portion, and the first projecting portion, the second projecting portion and the third projecting portion are connected to each other. Each of the protruding portions is bent outward with respect to the storage portion, and further includes a lid portion adhered to the first protruding portion, the second protruding portion and the third protruding portion. As a result, when the first projecting portion and the second projecting portion are bent outward, a V-shaped notch is formed between both ends of the first projecting portion and the projecting portion of the second projecting portion. difficult to form. Thereby, it is possible to maintain the airtightness when the flange portion is heat-bonded.

上記構成において、前記第２張出部の前記突出部は一対の前記側面部よりも内側に突出した重ね部を備え、前記重ね部は、前記第１張出部および第３張出部の両端部と重なるようにしてもよい。このように構成することで、第１張出部および第３張出部の両端部と、第２張出部の突出部とを重ねることができる。これにより、第１張出部と第２張出部との境界部分、および、第３張出部と第２張出部との境界部分における気密性をより高めることが可能である。 In the above configuration, the protruding portion of the second protruding portion includes overlapping portions that protrude inward from the pair of side portions, and the overlapping portions are arranged at both ends of the first protruding portion and the third protruding portion. You may make it overlap with a part. By configuring in this way, both end portions of the first projecting portion and the third projecting portion can be overlapped with the projecting portion of the second projecting portion. Thereby, it is possible to further improve the airtightness at the boundary portion between the first projecting portion and the second projecting portion and at the boundary portion between the third projecting portion and the second projecting portion.

上記構成において、前記蓋部は、第１張出部、第２張出部および第３張出部のいずれかと一体的に形成されていてもよい。このように構成することで、１枚の紙で容器を完成させることが可能である。 In the above configuration, the lid portion may be formed integrally with any one of the first projecting portion, the second projecting portion, and the third projecting portion. By configuring in this way, it is possible to complete the container with one sheet of paper.

上記構成において、前記第２面部と前記側面部の第２辺とは直接的に連設され、前記第１張出部および前記第２張出部は、それぞれ、前記収納部に対して外側に折り曲げられており、前記第３張出部を前記第２面部との境界線で折り曲げて蓋部として前記第１張出部および前記第２張出部に接着するようにしてもよい。このように構成することで、１枚の紙で容器を完成させることが可能である。また、折り返し部を減らすことができるため、折り返し部の折り返し作業を減らすことができるため、容器の製造に要する手間および時間を減らすことができる。 In the above configuration, the second surface portion and the second side of the side surface portion are directly connected to each other, and the first projecting portion and the second projecting portion extend outward with respect to the storage portion. The third protruding portion may be bent at a boundary line with the second surface portion and adhered to the first protruding portion and the second protruding portion as a lid portion. By configuring in this way, it is possible to complete the container with one sheet of paper. In addition, since the number of fold-back portions can be reduced, the work of folding the fold-back portions can be reduced, so that the labor and time required for manufacturing the container can be reduced.

上記構成において、前記第２張出部の前記突出部は一対の前記側面部よりも内側に突出した重ね部を備え、前記重ね部は、前記第１張出部の両端部と重なるようにしてもよい。これにより、第１張出部と第２張出部との境界部分における気密性をより高めることが可能である。 In the above configuration, the projecting portion of the second projecting portion includes overlapping portions projecting inwardly from the pair of side surfaces, and the overlapping portions overlap both end portions of the first projecting portion. good too. Thereby, it is possible to further improve airtightness at the boundary portion between the first projecting portion and the second projecting portion.

Also, the first folded portion 4 is connected to the first side 31 of the side portion 3 via the third folding line L3. That is, the side portion 13 of the first surface portion 1 and the first side portion 31 of the side surface portion 3 are indirectly connected by the first folded portion 4 .

第１折り返し部４の中間部には、第２折り線Ｌ２と第３折り線Ｌ３との交点から外縁に向かって延びる第８折り線Ｌ８を備える。第１折り返し部４は、第８折り線Ｌ８にて、第１面部１側に配置される第１外折り部４１と側面部３側に配置される第１内折り部４２とに分割される。第１折り返し部４において、第１外折り部４１と、第１内折り部４２とは、同一の形状であり、ここでは、三角形状である。すなわち、第８折り線Ｌ８は、第１外折り部４１および第１内折り部４２の一辺を構成する。 An intermediate portion of the first folded portion 4 is provided with an eighth folding line L8 extending from the intersection of the second folding line L2 and the third folding line L3 toward the outer edge. The first folded portion 4 is divided at the eighth folding line L8 into a first outer folded portion 41 arranged on the first surface portion 1 side and a first inward folded portion 42 arranged on the side surface portion 3 side. . In the first folded portion 4, the first outer folded portion 41 and the first inner folded portion 42 have the same shape, and are triangular in this case. That is, the eighth folding line L8 constitutes one side of the first outer folding portion 41 and the first inner folding portion 42 .

第１外折り部４１および第１内折り部４２の第８折り線Ｌ８と対向する角部の角度θ１は、側面部３の第１辺３１と第３辺３３とがなす角部の角度γ１以下である。すなわち、角度θ１と角度γ１とに、θ１≦γ１の関係が成り立つように、第１外折り部４１および第１内折り部４２とが形成される。詳細は後述するが、ここでは、θ１＝γ１としている（図４参照）。 The angle θ1 of the corners of the first outwardly folded portion 41 and the first inwardly folded portion 42 facing the eighth folding line L8 is the angle γ1 of the corners formed by the first side 31 and the third side 33 of the side surface portion 3. It is below. That is, the first outer folded portion 41 and the first inner folded portion 42 are formed such that the relationship θ1≦γ1 is established between the angles θ1 and γ1. Details will be described later, but here, θ1=γ1 (see FIG. 4).

第２折り返し部５は、第２面部２の側辺部２３と側面部３の第２辺３２との間に配置される。図４に示すように、第２折り返し部５は、第２面部２の側辺部２３と第４折り線Ｌ４を介して連設される。また、第２折り返し部５は、側面部３の第２辺３２と第５折り線Ｌ５を介して連設される。すなわち、第２折り返し部５によって、第２面部２の側辺部２３と側面部３の第２辺３２とが間接的に連設される。 The second folded portion 5 is arranged between the side portion 23 of the second surface portion 2 and the second side 32 of the side surface portion 3 . As shown in FIG. 4, the second folded portion 5 is connected to the side portion 23 of the second surface portion 2 via the fourth folding line L4. Further, the second folded portion 5 is connected to the second side 32 of the side portion 3 via the fifth folding line L5. That is, the side portion 23 of the second surface portion 2 and the second side portion 32 of the side surface portion 3 are indirectly connected by the second folded portion 5 .

第２折り返し部５の中間部には、第４折り線Ｌ４と第５折り線Ｌ５との交点から外縁に向かって延びる第９折り線Ｌ９を備える。第２折り返し部５は、第９折り線Ｌ９にて、第２面部２側に配置される第２外折り部５１と側面部３側に配置される第２内折り部５２とに分割される。第２折り返し部５において、第２外折り部５１と、第２内折り部５２とは、同一の形状であり、ここでは、三角形状である。第９折り線Ｌ９は、第２外折り部５１および第２内折り部５２の一辺を構成する。 An intermediate portion of the second folded portion 5 is provided with a ninth folding line L9 extending from the intersection of the fourth folding line L4 and the fifth folding line L5 toward the outer edge. The second folded portion 5 is divided at a ninth fold line L9 into a second outer folded portion 51 arranged on the second surface portion 2 side and a second inward folded portion 52 arranged on the side surface portion 3 side. . In the second folded portion 5, the second outer folded portion 51 and the second inner folded portion 52 have the same shape, and are triangular in this case. The ninth folding line L9 constitutes one side of the second outer folding portion 51 and the second inner folding portion 52 .

第２外折り部５１および第２内折り部５２の第９折り線Ｌ９と対向する角部の角度θ２は、側面部３の第２辺３２と第３辺３３とがなす角部の角度γ２以下である。すなわち、角度θ２と角度γ２とに、θ２≦γ２の関係が成り立つように、第２外折り部５１および第２内折り部５２とが形成される。詳細は後述するが、ここでは、θ２＝γ２としている（図４参照）。紙シートＰｓは以上の構成を有している。 The angle θ2 of the corners of the second outwardly folded portion 51 and the second inwardly folded portion 52 facing the ninth folding line L9 is the angle γ2 of the corner formed by the second side 32 and the third side 33 of the side surface portion 3. It is below. That is, the second outer folded portion 51 and the second inner folded portion 52 are formed such that the relationship θ2≦γ2 is established between the angles θ2 and γ2. Details will be described later, but here, θ2=γ2 (see FIG. 4). The paper sheet Ps has the above configuration.

（３．容器Ａの組み立て）
次に、容器Ａの組み立てについて説明する。まず、第１折り線Ｌ１を山折りして、第１面部１と第２面部２とを一定の角度をなすように折り曲げる。ここでは、第１面部１と第２面部２とは、略直交するように折り曲げられる。 (3. Assembly of container A)
Next, assembly of the container A will be described. First, the first folding line L1 is mountain-folded, and the first surface portion 1 and the second surface portion 2 are bent at a constant angle. Here, the first surface portion 1 and the second surface portion 2 are bent so as to be substantially perpendicular to each other.

そして、第８折り線Ｌ８を山折りする。これにより、第１折り返し部４の第１外折り部４１と第１内折り部４２とが重なる。このとき、第２折り線Ｌ２と第３折り線Ｌ３とが重なる。そして、第２折り線Ｌ２を山折り、第３折り線Ｌ３を谷折りすることで、第１折り返し部４の第１外折り部４１および第１内折り部４２とを重ねた部分は、側面部３の外側に折り返される。 Then, the eighth folding line L8 is mountain-folded. As a result, the first outer folded portion 41 and the first inner folded portion 42 of the first folded portion 4 are overlapped. At this time, the second folding line L2 and the third folding line L3 overlap. Then, by mountain-folding the second folding line L2 and valley-folding the third folding line L3, the overlapped portion of the first outer folded portion 41 and the first inner folded portion 42 of the first folded portion 4 becomes a side surface. It is folded to the outside of part 3 .

第１外折り部４１および第１内折り部４２の第８折り線Ｌ８と対向する角部の角度θ１が側面部３の第１辺３１と第３辺３３とで形成される角度γ１以下である。そのため、第２折り線Ｌ２および第３折り線Ｌ３で折り返された第１外折り部４１および第１内折り部４２を重ねた部分は、側面部３内に収まる。なお、角度θ１が大きい方が、強度が高くなる。そのため、ここでは、θ１＝γ１としている（図３、図４参照）。 The angle θ1 of the corners of the first outwardly folded portion 41 and the first inwardly folded portion 42 facing the eighth folding line L8 is less than or equal to the angle γ1 formed by the first side 31 and the third side 33 of the side portion 3. be. Therefore, the overlapped portion of the first outer folded portion 41 and the first inner folded portion 42 folded back along the second folding line L2 and the third folding line L3 fits within the side surface portion 3 . Note that the larger the angle θ1, the higher the strength. Therefore, θ1=γ1 is set here (see FIGS. 3 and 4).

そして、重なった第１外折り部４１および第１内折り部４２は、第１内折り部４２が側面部３の外面と接触する。このとき、第１内折り部４２と側面部３の外面とを接着する。接着は、例えば、接着剤を用いた接着を挙げることができる。第１内折り部４２と側面部３の外面とは、容器Ａの内部に収納する収納物Ｓと直接接触するのを抑制できる。そのため、接着剤としては、特に限定されるものではなく、従来よく知られたものを利用可能である。 As for the first outwardly folded portion 41 and the first inwardly folded portion 42 that overlap each other, the first inwardly folded portion 42 contacts the outer surface of the side portion 3 . At this time, the first inwardly folded portion 42 and the outer surface of the side portion 3 are adhered. Adhesion can include, for example, adhesion using an adhesive. The first inward folding portion 42 and the outer surface of the side surface portion 3 can suppress direct contact with the stored article S stored inside the container A. As shown in FIG. Therefore, the adhesive is not particularly limited, and conventionally well-known adhesives can be used.

次に、第９折り線Ｌ９を山折りする。これにより、第２折り返し部５の第２外折り部５１と第２内折り部５２とが重なる。このとき、第４折り線Ｌ４と第５折り線Ｌ５とが重なる。そして、第４折り線Ｌ４を山折り、第５折り線Ｌ５を谷折りすることで、第２外折り部５１および第２内折り部５２を重ねた部分は、側面部３の外側に折り返される。 Next, a mountain fold is made along the ninth folding line L9. As a result, the second outer folded portion 51 and the second inner folded portion 52 of the second folded portion 5 are overlapped. At this time, the fourth folding line L4 and the fifth folding line L5 overlap. Then, by mountain-folding the fourth folding line L4 and valley-folding the fifth folding line L5, the overlapped portion of the second outer folded portion 51 and the second inner folded portion 52 is folded back to the outside of the side portion 3. .

第２外折り部５１および第２内折り部５２の第９折り線Ｌ９と対向する角部の角度θ２が側面部３の第１辺３１と第３辺３３とで形成される角度γ２以下である。そのため、第４折り線Ｌ４および第５折り線Ｌ５で折り返された第２外折り部５１および第２内折り部５２を重ねた部分は、側面部３内に収まる。なお、角度θ２の大きさが大きい方が、強度が高くなる。そのため、ここでは、θ２＝γ２としている（図３、図４参照）。 The angle θ2 of the corners of the second outwardly folded portion 51 and the second inwardly folded portion 52 facing the ninth folding line L9 is less than or equal to the angle γ2 formed by the first side 31 and the third side 33 of the side portion 3. be. Therefore, the overlapping portion of the second outer folded portion 51 and the second inner folded portion 52 folded back along the fourth folding line L4 and the fifth folding line L5 fits within the side surface portion 3 . Note that the larger the angle θ2, the higher the strength. Therefore, θ2=γ2 is set here (see FIGS. 3 and 4).

そして、重なった第２外折り部５１および第２内折り部５２は、第２内折り部５２が側面部３の外面と接触する。このとき、第２内折り部５２と側面部３の外面とを接着する。接着は、例えば、接着剤を用いた接着を挙げることができる。第２内折り部５２と側面部３の外面とは、容器Ａの内部に収納する収納物Ｓと直接接触するのを抑制できる。 As for the second outer folded portion 51 and the second inner folded portion 52 that overlap each other, the second inner folded portion 52 comes into contact with the outer surface of the side portion 3 . At this time, the second inwardly folded portion 52 and the outer surface of the side portion 3 are adhered. Adhesion can include, for example, adhesion using an adhesive. The second inwardly folded portion 52 and the outer surface of the side portion 3 can suppress direct contact with the stored article S stored inside the container A.

以上のように、第２折り線Ｌ２、第３折り線Ｌ３、第４折り線Ｌ４、第５折り線Ｌ５、第８折り線Ｌ８および第９折り線Ｌ９を折り曲げることで、左側の側面部３を折り曲げた第１面部１および第２面部２の左側に組み付けることができる。なお、第１面部１の左側の側辺部１３と側面部３の第１辺３１とが重なり、第２面部２の左側の側辺部２３と側面部３の第２辺３２とが重なる。 As described above, by folding the second folding line L2, the third folding line L3, the fourth folding line L4, the fifth folding line L5, the eighth folding line L8, and the ninth folding line L9, the left side portion 3 can be assembled to the left side of the folded first surface portion 1 and the second surface portion 2. The left side portion 13 of the first surface portion 1 and the first side portion 31 of the side portion 3 overlap, and the left side portion 23 of the second surface portion 2 and the second side portion 32 of the side portion 3 overlap.

また、右側の第２折り線Ｌ２、第３折り線Ｌ３、第４折り線Ｌ４、第５折り線Ｌ５、第８折り線Ｌ８および第９折り線Ｌ９を、折り曲げることで、右側の側面部３を第１面部１および第２面部２の右側に組み付けることができる。なお、第１面部１の右側の側辺部１３と側面部３の第１辺３１とが重なり、第２面部２の右側の側辺部１３と側面部３の第２辺３２とが重なる。 In addition, by folding the second folding line L2, the third folding line L3, the fourth folding line L4, the fifth folding line L5, the eighth folding line L8, and the ninth folding line L9 on the right side, the right side portion 3 can be assembled to the right side of the first surface portion 1 and the second surface portion 2. The right side portion 13 of the first surface portion 1 and the first side 31 of the side portion 3 overlap, and the right side portion 13 of the second surface portion 2 and the second side 32 of the side portion 3 overlap.

このように、第１面部１、第２面部２および一対の側面部３、３を組み立てることで、第１面部１の下底部１２、第２面部２の下底部２２および一対の側面部３、３の第３辺３３、３３で囲まれた長方形状の開口Ｏｐを有する収納部Ｃｔが形成される。1枚の紙シートＰｓで収納部Ｃｔを形成することができるとともに、角部等につなぎ目が形成されないため、容器Ａは外力に対する強度が高い。そのため、収納物Ｓを保護する保護力を高めることができる。 By assembling the first surface portion 1, the second surface portion 2, and the pair of side surfaces 3, 3 in this manner, the lower bottom portion 12 of the first surface portion 1, the lower bottom portion 22 of the second surface portion 2, and the pair of side surface portions 3, A storage portion Ct having a rectangular opening Op surrounded by three third sides 33, 33 is formed. Since the storage portion Ct can be formed by one sheet of paper Ps and no joints are formed at the corners or the like, the container A has high strength against external force. Therefore, it is possible to enhance the protective force for protecting the stored items S.

そして、第１面部１の下底部１２に配置された第６折り線Ｌ６および第２面部２の下底部２２に配置された第６折り線Ｌ６で谷折りして、第１張出部６および第３張出部８を外側に折り曲げる。この時、第１張出部６および第３張出部８は、開口Ｏｐが含まれる面と同一面になるように折り曲げられる。 Then, it is valley-folded along the sixth folding line L6 arranged on the lower bottom portion 12 of the first surface portion 1 and the sixth folding line L6 arranged on the lower bottom portion 22 of the second surface portion 2 to form the first protruding portion 6 and The third projecting portion 8 is bent outward. At this time, the first protruding portion 6 and the third protruding portion 8 are bent so as to be flush with the plane including the opening Op.

また、一対の側面部３、３それぞれの第３辺３３、３３に配置された第７折り線Ｌ７で谷折りすることで、第２張出部７を外側に折り曲げる。この時、第２張出部７は、開口Ｏｐが含まれる面と同一面になるように折り曲げられる。 Further, by valley-folding along the seventh folding lines L7 arranged on the third sides 33, 33 of the pair of side portions 3, 3, respectively, the second projecting portion 7 is bent outward. At this time, the second protruding portion 7 is bent so as to be on the same plane as the plane including the opening Op.

そして、容器Ａでは、開口Ｏｐから収納部Ｃｔに収納物Ｓを収納する。そして、ポリエチレンテレフタレート（ＰＥＴ）、ポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）等を含む透明シートで形成された蓋部Ｆｐを第１張出部６、第２張出部７および第３張出部８に熱接着する。これにより、蓋部Ｆｐが開口Ｏｐを封止し、収納部Ｃｔに収納物Ｓが収納された容器Ａが形成される。すなわち、第１張出部６、第２張出部７および第３張出部８は、蓋部Ｆｐを貼り付けるためのフランジ部の役割を果たす。 Then, in the container A, the storage item S is stored in the storage portion Ct from the opening Op. Then, the lid portion Fp formed of a transparent sheet containing polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), or the like is attached to the first projecting portion 6, the second projecting portion 7, and the third projecting portion 8. heat-bonded to As a result, the lid portion Fp seals the opening Op, and the container A in which the storage item S is stored in the storage portion Ct is formed. That is, the first protruding portion 6, the second protruding portion 7, and the third protruding portion 8 serve as flange portions for attaching the lid portion Fp.

紙シートＰｓでは、一対の側面部３、３と第１面部１および第２面部２とを第１折り返し部４および第２折り返し部５を介して間接的に連結される。そのため、紙シートＰｓにおいて第１張出部６と第２張出部７、および、第３張出部８と第２張出部７がそれぞれ離れた位置に形成される（図４参照）。これにより、第２張出部７の両端部に、突出部７１を形成できる。第２張出部７の突出部７１は、第１張出部６および第３張出部８の両端部と隣接する。 In the paper sheet Ps, the pair of side surface portions 3, 3 and the first surface portion 1 and the second surface portion 2 are indirectly connected via the first folded portion 4 and the second folded portion 5, respectively. Therefore, the first projecting portion 6 and the second projecting portion 7, and the third projecting portion 8 and the second projecting portion 7 are formed at separate positions on the paper sheet Ps (see FIG. 4). Thereby, the projecting portions 71 can be formed at both end portions of the second projecting portion 7 . The projecting portion 71 of the second projecting portion 7 is adjacent to both end portions of the first projecting portion 6 and the third projecting portion 8 .

このように形成することで、第１張出部６と第２張出部７との間にＶ字状の切欠きが形成されない。同様に、第３張出部８と第２張出部７との間にＶ字状の切欠きが形成されない。そのため、蓋部Ｆｐと開口Ｏｐとの隙間ができにくくなる。これにより、容器Ａの気密性を高めることが可能である。 By forming in this way, a V-shaped notch is not formed between the first projecting portion 6 and the second projecting portion 7 . Similarly, a V-shaped notch is not formed between the third projecting portion 8 and the second projecting portion 7 . Therefore, it becomes difficult to form a gap between the lid portion Fp and the opening Op. Thereby, the airtightness of the container A can be improved.

収納物Ｓの容器Ａの収納部Ｃｔへの収納は、収納物Ｓの容器Ａの収納部Ｃｔへの収納と、容器Ａの組み立てとは別の場所（装置）で行われる場合がある。そして、収納物Ｓを効率よく容器Ａに収納するために、ある程度の数の容器Ａを組み立てて準備しておく場合がある。そして、容器Ａの開口Ｏｐを下にして配置する。そして、その上から、下に配置された容器Ａの第１面部１、第２面部２および一対の側面部３、３が開口Ｏｐから収納部Ｃｔの内部に挿入されるように重ねる。 There are cases where the storing of the articles S in the storage portion Ct of the container A and the assembly of the container A are performed in a different place (apparatus). In some cases, a certain number of containers A are assembled and prepared in order to store the articles S in the containers A efficiently. Then, the opening Op of the container A is placed downward. Then, the container A placed below is stacked so that the first surface portion 1, the second surface portion 2 and the pair of side surfaces 3, 3 are inserted into the storage portion Ct through the opening Op.

このとき、容器Ａにおいて第１折り返し部４および第２折り返し部５が側面部３の外側に形成される。そして、このような折り返し部分は、開いている部分（窓部とする）に外部の部材が接触すると、接着が外れる場合がある。第１折り返し部４および第２折り返し部５の窓部は、開口Ｏｐ側に形成される。そのため、上から容器Ａが配置されても、下側の容器Ａの第１折り返し部４および第２折り返し部５の接着が容器Ａによって外れにくい。また、上から配置される容器Ａでは、開口Ｏｐから内部に下側の容器Ａの第１面部１、第２面部２および一対の側面部３が挿入される。下側の容器Ａは、上側の容器Ａの第１折り返し部４および第２折り返し部５に干渉しない。そのため、容器Ａは、開口Ｏｐから他の容器Ａを挿入して重ねても、第１折り返し部４および第２折り返し部５が外れにくく、容器Ａが壊れにくい。 At this time, in the container A, the first folded portion 4 and the second folded portion 5 are formed outside the side surface portion 3 . Such a folded portion may be unbonded when an external member comes into contact with the open portion (referred to as a window portion). The windows of the first folded portion 4 and the second folded portion 5 are formed on the opening Op side. Therefore, even if the container A is placed from above, the adhesion of the first folded portion 4 and the second folded portion 5 of the container A on the lower side is less likely to come off due to the container A. Further, in the container A arranged from above, the first surface portion 1, the second surface portion 2 and the pair of side surface portions 3 of the container A on the lower side are inserted into the inside from the opening Op. The container A on the lower side does not interfere with the first folded portion 4 and the second folded portion 5 of the container A on the upper side. Therefore, even if another container A is inserted through the opening Op and stacked, the first folded portion 4 and the second folded portion 5 are less likely to come off, and the container A is less likely to break.

本実施形態の容器Ａによれは、収納部Ｃｔを蓋部Ｆｐで隙間なく封止できる。そして、一方の容器Ａの第１面部１、第２面部２および側面部３を他方の容器Ａの収納部Ｃｔに収納して重ねる場合でも第１折り返し部４および第２折り返し部５の接着が外れにくく、容器Ａが壊れにくい。 According to the container A of the present embodiment, the storage portion Ct can be tightly sealed with the lid portion Fp. Even when the first surface portion 1, the second surface portion 2 and the side surface portion 3 of one container A are accommodated in the storage portion Ct of the other container A and stacked, the adhesion of the first folded portion 4 and the second folded portion 5 can be achieved. It is hard to come off, and the container A is hard to break.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 9 is a perspective view of still another example of the container according to the invention. 10 is an exploded view of the container shown in FIG. 9. FIG. The container E of the present embodiment has the same configuration as the container A of the first embodiment, except that the second surface portion 2e, the side surface portion 3e, the second projecting portion 7e, and the third projecting portion 8e are different. Therefore, substantially the same portions of the container E as those of the container A are denoted by the same reference numerals, and detailed description of the same portions is omitted.

図９、図１０に示すように、容器Ｅでは、第２面部２ｅの側辺部２３ｅと側面部３ｅの第２辺３２ｅとが第１１折り線Ｌ１１を介して直接的に連設されている。なお、第１面部１の側辺部１３と側面部３ｅの第１辺３１とは、折り返し部（第１折り返し部４）を介して直接的に連設されている。 As shown in FIGS. 9 and 10, in the container E, the side portion 23e of the second surface portion 2e and the second side portion 32e of the side surface portion 3e are directly connected via the eleventh folding line L11. . The side portion 13 of the first surface portion 1 and the first side portion 31 of the side surface portion 3e are directly connected to each other via a folded portion (first folded portion 4).

さらに、第３張出部８ｅは、第１２折り線Ｌ１２を介して第２面部２ｅの下底部２２と直接連設されている。図１０に示すように、第３張出部８ｅは、角部が丸められた長方形状である。第３張出部８ｅの左右幅は、下底部２２の長さよりも長い。詳しく説明すると、第３張出部８ｅは、下底部２２の両端から第２張出部７ｅの幅と同じまたは略同じだけ延びた横幅を有する。また、第３張出部８ｅの縦の長さは、第２張出部７ｅと同じである。第２張出部７ｅは、第１張出部６側、すなわち、折り返し部（第１折り返し部４）と隣接する側にだけ、突出部７１を備えている。 Further, the third protruding portion 8e is directly connected to the bottom portion 22 of the second surface portion 2e via the twelfth folding line L12. As shown in FIG. 10, the third projecting portion 8e has a rectangular shape with rounded corners. The lateral width of the third projecting portion 8 e is longer than the length of the lower bottom portion 22 . More specifically, the third projecting portion 8e has a lateral width that extends from both ends of the lower bottom portion 22 by the same or substantially the same width as the second projecting portion 7e. Also, the vertical length of the third projecting portion 8e is the same as that of the second projecting portion 7e. The second protruding portion 7e has a protruding portion 71 only on the side of the first protruding portion 6, that is, on the side adjacent to the folded portion (first folded portion 4).

図１０に示すように、紙シートＰｓｅにおいて、第２張出部７ｅと第３張出部８ｅとは、隣接している。そして、第２張出部７ｅと第３張出部８ｅとの境界部分には、第１２折り線Ｌ１２の延長線と重なる切れ込み８１ｅが設けられている。切れ込み８１ｅを備えることで、第３張出部８ｅは、第１２折り線Ｌ１２を左右に延ばした辺を有する形状である。紙シートＰｓｅは、以上のような構成を有する。次に、紙シートＰｓｅを折り曲げることによる容器Ｅの組み立てについて説明する。 As shown in FIG. 10, in the paper sheet Pse, the second projecting portion 7e and the third projecting portion 8e are adjacent to each other. A notch 81e overlapping the extension of the twelfth folding line L12 is provided at the boundary between the second projecting portion 7e and the third projecting portion 8e. By providing the notch 81e, the third protruding portion 8e has a shape having sides extending left and right from the twelfth folding line L12. The paper sheet Pse has the configuration described above. Next, assembly of the container E by folding the paper sheet Pse will be described.

まず、第１折り線Ｌ１を山折りして、第１面部１と第２面部２ｅとを一定の角度をなすように折り曲げる。ここでは、第１面部１と第２面部２ｅとは、略直交するように折り曲げられる。 First, the first folding line L1 is mountain-folded, and the first surface portion 1 and the second surface portion 2e are bent at a constant angle. Here, the first surface portion 1 and the second surface portion 2e are bent so as to be substantially perpendicular to each other.

そして、第８折り線Ｌ８を山折りする。これにより、第１折り返し部４の第１外折り部４１と第１内折り部４２とが重なる。このとき、第２折り線Ｌ２と第３折り線Ｌ３とが重なる。そして、第２折り線Ｌ２を山折り、第３折り線Ｌ３を谷折りすることで、第１折り返し部４の第１外折り部４１および第１内折り部４２とを重ねた部分は、側面部３ｅの外側に折り返される。 Then, the eighth folding line L8 is mountain-folded. As a result, the first outer folded portion 41 and the first inner folded portion 42 of the first folded portion 4 are overlapped. At this time, the second folding line L2 and the third folding line L3 overlap. Then, by mountain-folding the second folding line L2 and valley-folding the third folding line L3, the overlapped portion of the first outer folded portion 41 and the first inner folded portion 42 of the first folded portion 4 becomes a side surface. It is folded to the outside of the portion 3e.

そして、重なった第１外折り部４１および第１内折り部４２は、第１内折り部４２が側面部３ｅの外面と接触する。このとき、第１内折り部４２と側面部３ｅの外面とを接着する。 As for the first outwardly folded portion 41 and the first inwardly folded portion 42 that overlap each other, the first inwardly folded portion 42 contacts the outer surface of the side portion 3e.

また、一対の側面部３ｅ、３ｅそれぞれの第３辺３３、３３に配置された第７折り線Ｌ７で谷折りすることで、第２張出部７ｅを外側に折り曲げる。この時、第２張出部７ｅは、開口Ｏｐが含まれる面と同一面になるように折り曲げられる。 Further, by valley-folding along the seventh folding lines L7 arranged on the third sides 33, 33 of each of the pair of side portions 3e, 3e, the second projecting portion 7e is bent outward. At this time, the second projecting portion 7e is bent so as to be flush with the surface including the opening Op.

そして、容器Ａの開口Ｏｐから、収納部Ｃｔに収納物Ｓを収納する。その後、第１２折り線Ｌ１２で山折りすることで、第３張出部８ｅが開口Ｏｐを覆うように折り曲げられる。そして、第３張出部８ｅの辺縁部を第１張出部６および第２張出部７に接着して固定する。これにより、第３張出部８ｅが蓋部Ｆｐｅとして開口Ｏｐを封止し、収納部Ｃｔに収納物Ｓが収納された容器Ｅが形成される。すなわち、第１張出部６および第２張出部７ｅは、蓋部Ｆｐｅ（第３張出部８ｅ）を貼り付けるためのフランジ部の役割を果たす。 Then, from the opening Op of the container A, the stored article S is stored in the storage portion Ct. Then, by mountain-folding along the twelfth folding line L12, the third projecting portion 8e is folded so as to cover the opening Op. Then, the edge portion of the third projecting portion 8e is adhered to the first projecting portion 6 and the second projecting portion 7 and fixed.
