Description

この発明は、合成樹脂製の折り畳み容器に関するものである。   The present invention relates to a synthetic resin folding container.

従来より、物品を輸送する場合、物品を容器に収納し、容器をトラックなどに積載して目的地まで輸送する一方、物品の輸送が終了して空になった容器を再びトラックなどに積載して回収するようにしている。   Conventionally, when transporting an article, the article is stored in a container, and the container is loaded on a truck or the like and transported to a destination. On the other hand, an empty container after the transportation of the article is loaded on a truck or the like again. To collect.

この場合、空の容器をそのまま回収すると、輸送効率が低下することから、返送時には折り畳んで容積を減少できる容器が考案されている。   In this case, if an empty container is recovered as it is, the transport efficiency is lowered. Therefore, a container that can be folded at the time of return to reduce the volume has been devised.

このような容器１００は、図１２および図１３に示すように、対向する一対の短辺枠材１０１および長辺枠材１０２からなる上枠体１０３と、方形状の底板１０４と、一対の短側板１０５と、上部長側板１０６の下端部および下部長側板１０７の上端部が折り畳み自在に連結された一対の長側板１０８と、から構成され、上枠体１０３の各短辺枠材１０１の下端部に各短側板１０５の上端部がそれぞれ回動自在に連結され、また、上枠体１０３の各長辺枠材１０２の下端部に各長側板１０８における上部長側板１０６の上端部がそれぞれ回動自在に連結される一方、底板１０６の各長辺側端縁部に各長側板１０８における下部長側板１０７の下端部がそれぞれ回動自在に連結されて形成されている（例えば、特許文献１参照）。   As shown in FIGS. 12 and 13, such a container 100 includes an upper frame 103 composed of a pair of opposing short side frame members 101 and long side frame members 102, a rectangular bottom plate 104, and a pair of short side plates 104. A lower plate of each short side frame member 101 of the upper frame 103 is composed of a side plate 105 and a pair of long side plates 108 in which the lower end portion of the upper long side plate 106 and the upper end portion of the lower long side plate 107 are foldably connected. The upper end of each short side plate 105 is pivotally connected to each other, and the upper end of the upper long side plate 106 of each long side plate 108 is rotated to the lower end of each long side frame member 102 of the upper frame 103. On the other hand, the bottom plate 106 is formed such that the lower end portion of the lower long side plate 107 of each long side plate 108 is rotatably connected to each long side end edge portion of the bottom plate 106 (for example, Patent Document 1). reference).

そして、対向する一対の短側板１０５の外面側下部を内方に押し込んで上枠体１０３に対してそれぞれ跳ね上げた後、対向する一対の長側板１０８の、上部長側板１０６および下部長側板１０７の連結部を内方に押し込むことにより、上枠体１０３と底板１０４との間に各長側板１０８をそれぞれ二つ折り状態に折曲して収納することができる。この際、短側板１０５は、上枠体１０３の内方において、二つ折りされた長側板１０８の上に積み重ねられる。   And after pushing inward the lower part of the outer surface side of a pair of opposing short side board 105 inward and jumping up with respect to the upper frame 103, respectively, the upper long side board 106 and the lower long side board 107 of a pair of opposing long side board 108 are demonstrated. By pushing the connecting portion inward, the long side plates 108 can be folded and stored in a folded state between the upper frame 103 and the bottom plate 104. At this time, the short side plate 105 is stacked on the long side plate 108 folded in half inside the upper frame 103.

また、折り畳み状態から上枠体１０３を持ち上げ、二つ折りされた上部長側板１０６および下部長側板１０７を伸展させて各長側板１０８を底板１０４に対して垂直状態に立ち上げた後、各短側板１０５をそれぞれ上枠体１０３に対して押し下げることにより、底板１０４に対して垂直状態に立ち上げ、容器１００を組み立てることができる。   Further, after lifting the upper frame 103 from the folded state and extending the folded upper long side plate 106 and lower long side plate 107 to raise each long side plate 108 to the vertical state with respect to the bottom plate 104, each short side plate By pushing down each of the 105 with respect to the upper frame 103, the container 100 can be assembled in a vertical state with respect to the bottom plate 104.

このような構造の容器においては、容器を組み立てて物品を収容し、積み重ねた状態で保管する場合、収納された物品を取り出し、あるいは、収容するためには、積み重ねた容器をいちいち下ろして作業しなければならず、作業効率が低下するという問題がある。このため、容器の一側面に開口部を形成するとともに、該一側面に開口部を開閉する扉を取り付けた折り畳み容器が提案されている（例えば、特許文献２，３参照）。また、容器の一側面に開口部を形成した折り畳み容器も市販されている。
実開昭５８−１１９５２５号公報 特公平５−２５７４３号公報 実開平７−８２２０号公報 In a container having such a structure, when assembling the container to store the articles and storing them in a stacked state, in order to take out or store the stored articles, the stacked containers must be lowered one by one. There is a problem that the work efficiency is lowered. For this reason, a folding container has been proposed in which an opening is formed on one side of the container and a door that opens and closes the opening is attached to the one side (see, for example, Patent Documents 2 and 3). A folding container having an opening formed on one side surface of the container is also commercially available.

ところで、前述した特許文献２，３に示した折り畳み容器にあっては、容器を積み重ねた状態であっても、扉を開放することにより、開口部を通して収容された物品を取り出す
ことができ、所謂ピッキング容器として使用することができるものの、特許文献１に示した一般的な折り畳み容器に比較して構造が複雑になるとともに、部品点数が増加するため、コストがかさみ、高価となる問題がある。また、輸送容器として使用する際において、収容した物品の数量が少ない場合や、物品の性状が柔軟な場合、輸送途中で外部から短側板に衝撃などが作用すると、短側板が跳ね上がり、積み重ねた容器の荷崩れが発生するおそれがある。さらに、短側板を外方から押し込むと短側板を跳ね上げることができ、物品が盗難されるおそれもある。 By the way, in the folding containers shown in Patent Documents 2 and 3 described above, even if the containers are stacked, the articles accommodated through the openings can be taken out by opening the doors, so-called Although it can be used as a picking container, there is a problem that the structure is complicated and the number of parts is increased as compared with the general folding container shown in Patent Document 1, so that the cost is increased and the cost is increased. In addition, when used as a transport container, if the quantity of stored items is small or the properties of the articles are flexible, if an impact is applied to the short side plate from the outside during transport, the short side plate jumps up and is stacked There is a risk of collapse of cargo. Furthermore, when the short side plate is pushed in from the outside, the short side plate can be flipped up, and the article may be stolen.

一方、容器の一側面に扉を付設することなく開口部を形成したのみの折り畳み容器にあっては、ピッキング容器として使用することはできるものの、開口部を開放したままでは、輸送容器として使用することはできない。   On the other hand, a folding container in which an opening is only formed without attaching a door to one side of the container can be used as a picking container, but it can be used as a transport container with the opening left open. It is not possible.

本発明は、このような問題点に鑑みてなされたもので、構造が簡単で安価に製造することができるとともに、ピッキング容器としても輸送容器としても使用することができる折り畳み容器を提供するものである。   The present invention has been made in view of such problems, and provides a folding container that is simple in structure and can be manufactured at low cost, and that can be used as a picking container and a transport container. is there.

本発明は、対向する一対の短辺枠材および長辺枠材からなる上枠体と、方形状の収容部およびその周縁に一体に形成された周縁部からなる底板と、上枠体の各短辺枠材の下端部に各上端部がそれぞれ回動自在に連結された一対の短側板と、それぞれ上部長側板の下端部および下部長側板の上端部が折り畳み自在に連結され、上枠体の各長辺枠材の下端部に各上部長側板の上端部がそれぞれ回動自在に連結されるとともに、底板の各長辺側周縁部に各下部長側板の下端部がそれぞれ回動自在に連結された一対の長側板と、から構成された折り畳み容器において、一方の長側板に開口部が形成され、また、底板の収容部表面の各長辺側端縁部および各短側板内面の左右各端縁部のうち、少なくとも一方の長側板に面する側の端縁部にそれぞれ係合部が形成されてなり、一方の長側板の内面に沿って差し込まれた側板が底板の係合部および短側板の係合部によって立設状態に保持されることを特徴とするものである。   The present invention includes an upper frame body composed of a pair of opposing short side frame members and long side frame members, a bottom plate composed of a rectangular housing portion and a peripheral edge portion formed integrally with the periphery thereof, and each of the upper frame body A pair of short side plates whose upper ends are rotatably connected to the lower end portions of the short side frame members, and a lower end portion of the upper long side plate and an upper end portion of the lower long side plate are connected to each other in a foldable manner. The upper end of each upper long side plate is pivotally connected to the lower end of each long side frame member, and the lower end of each lower long side plate is pivotable to each long side edge of the bottom plate. In a folding container constituted by a pair of long side plates connected to each other, an opening is formed in one long side plate, and left and right sides of each long side end edge portion and each short side plate inner surface of the housing portion surface of the bottom plate Engage with each of the end edges on the side facing the long side plate. There will be formed, it is characterized in that the side plate plugged along the inner surface of the long side plates is retained by the engagement portion of the engagement portion and the short side plate of the bottom plate to the upright position.

本発明によれば、対向する一対の短側板の外面側下部を内方に押し込み、上枠体に対して各短側板を跳ね上げた後、対向する一対の長側板における上部長側板および下部長側板の連結部を内方に押し込むことにより、上枠体と底板との間に各長側板を二つ折り状態に折曲して収納することができる。この際、短側板は、上枠体の内方において、二つ折りされた長側板の上に積み重ねられる。したがって、空の容器を回収する場合は、容器を折り畳んで容積を小さくして輸送することができ、輸送効率を向上させることができる。   According to the present invention, the lower part of the outer side of the pair of opposing short side plates is pushed inward, the respective short side plates are flipped up with respect to the upper frame, and then the upper long side plate and the lower portion of the pair of opposing long side plates. By pushing the connecting portion of the side plate inward, each long side plate can be folded in a folded state between the upper frame and the bottom plate. At this time, the short side plate is stacked on the long side plate folded in half inside the upper frame. Therefore, when collecting an empty container, the container can be folded to reduce the volume and transported, and the transport efficiency can be improved.

一方、折り畳み状態から上枠体を持ち上げ、二つ折りされた上部長側板および下部長側板を伸展させて底板に対して各長側板を垂直状態に立ち上げるとともに、各短側板を上枠体に対して押し下げ、底板に対して垂直状態に立ち上げることにより、容器を組み立てることができる。ここで、側板を一方の長側板の内面に沿って差し込むことにより、側板の左右各端縁および下端縁が短側板の係合部および底板の係合部に係合し、側板を立設状態に保持することができるとともに、一方の長側板に形成された開口部を閉鎖することができる。したがって、組み立てた容器に物品を収容した後、容器を積み重ねて保管し、あるいは、輸送することができる。この場合、側板の左右各端面は、短側板の内面と当接しており、短側板の意図しない跳ね上がりを規制することができ、輸送時あるいは積み卸し時における容器の荷崩れを防止できる。   On the other hand, the upper frame body is lifted from the folded state, the upper long side plate and the lower long side plate folded in half are extended, and each long side plate is raised to the vertical state with respect to the bottom plate. The container can be assembled by pushing it down and raising it vertically to the bottom plate. Here, by inserting the side plate along the inner surface of one long side plate, the left and right edges and the lower end edge of the side plate engage with the engaging portion of the short side plate and the engaging portion of the bottom plate, and the side plate stands upright. And the opening formed in one of the long side plates can be closed. Therefore, after storing articles in the assembled container, the containers can be stacked and stored or transported. In this case, the left and right end faces of the side plate are in contact with the inner surface of the short side plate, so that unintended jumping of the short side plate can be restricted, and container collapse during transportation or unloading can be prevented.

容器が目的地に到着すれば、一方の長側板から側板を引き上げて取り出すことにより、一方の長側板の開口部を開放することができる。したがって、容器を積み重ねた状態であっても、開口部を通して物品を取り出すことができる。また、輸送容器からピッキング容
器への物品の移し替えも不要となる。 If a container arrives at the destination, the opening part of one long side board can be open | released by pulling up and taking out a side board from one long side board. Therefore, even when the containers are stacked, the article can be taken out through the opening. Further, it is not necessary to transfer articles from the transport container to the picking container.

なお、係合部を、一方の長側板に面する側の、底板の収容部表面の長辺側端縁部および各短側板内面の左右一方の端縁部に形成するとともに、他方の長側板に面する側の、底板の収容部表面の長辺側端縁部および各短側板内面の左右他方の端縁部に合わせて形成してもよい。このように、他方の長側板に面する側の、底板の収容部表面の長辺側端縁部および各短側板内面の左右他方の端縁部にも係合部を形成すると、一方の長側板から引き上げた側板を他方の長側板に沿って差し込んで、その左右各端縁および下端縁を短側板の係合部および底板の係合部に係合させ、他方の側板に沿って立設状態に保持することが可能となる。したがって、一方の長側板から引き上げた側板を紛失しないように保管することができる。この場合も、側板の左右各端面が短側板の内面と当接することから、短側板の意図しない跳ね上がりを規制して、容器を積み重ねた際の荷崩れを防止できる。   In addition, while forming an engaging part in the long side edge part of the accommodating part surface of a baseplate on the side which faces one long side board, and one right and left edge part of each short side board inner surface, the other long side board You may form in accordance with the long side edge part of the accommodating part surface of a bottom plate, and the other left and right edge part of each short side plate inner surface on the side which faces. As described above, when the engaging portion is also formed on the long side edge of the surface of the bottom plate housing portion on the side facing the other long side plate and the other left and right edge portions of the inner surface of each short side plate, The side plate pulled up from the side plate is inserted along the other long side plate, and its left and right end edges and lower end edge are engaged with the engaging portion of the short side plate and the engaging portion of the bottom plate, and is erected along the other side plate. It is possible to hold the state. Therefore, the side plate pulled up from one long side plate can be stored so as not to be lost. Also in this case, since the left and right end surfaces of the side plate are in contact with the inner surface of the short side plate, unintentional jumping of the short side plate is restricted, and the collapse of the load when the containers are stacked can be prevented.

本発明の係合部としては、側板の左右各端縁および下端縁が係合可能な係合突起であってもよい他、側板の左右各端縁および／または下端縁が嵌合可能な係合溝であってもよく、また、係合突起と係合溝を併用してもかまわない。また、係合突起または係合溝は、連続して形成してもよく、間欠的に形成してもよい。   The engaging portion of the present invention may be an engaging protrusion that can be engaged with the left and right end edges and the lower end edge of the side plate, or the engagement that can be fitted with the left and right end edges and / or the lower end edge of the side plate. A mating groove may be used, and the engaging protrusion and the engaging groove may be used in combination. Further, the engagement protrusion or the engagement groove may be formed continuously or intermittently.

本発明において、前記側板は、短側板の回動操作に干渉することなく底板の収容部表面に載置可能であると、容器を折り畳んで回収する際、底板に側板を載置することができ、容器とは別に側板を保管して輸送する必要がなく、また、容器と一対一に対応付けて保管することができ、紛失のおそれもない。   In the present invention, when the side plate can be placed on the surface of the bottom plate accommodating portion without interfering with the rotation operation of the short side plate, the side plate can be placed on the bottom plate when the container is folded and collected. There is no need to store and transport the side plate separately from the container, and the container can be stored in one-to-one correspondence with the container, and there is no risk of loss.

本発明において、前記上枠体の各長辺枠材の上端部に蓋体が回動自在に連結されていると、蓋体によって容器の上方開口部を閉鎖することが可能となり、輸送容器として使用することができる。そして、例えば、蓋体を短側板に対して封緘して輸送すれば、密閉容器となることから、物品の盗難を防止できる。この場合、蓋体としては、観音開き方式であっても、片開き方式であってもかまわない。   In the present invention, when a lid is rotatably connected to the upper end of each long side frame member of the upper frame, the upper opening of the container can be closed by the lid, and as a transport container Can be used. For example, if the lid is sealed with respect to the short side plate and transported, it becomes a sealed container, so that the theft of the article can be prevented. In this case, the lid body may be a double door system or a single door system.

本発明において、前記蓋体の内面に、長側板の内面に沿って差し込まれた側板の上端部を係止可能な係止部が形成されていると、蓋体によって上方開口部を閉鎖した状態で物品を輸送する際、長側板の内面に沿って立設された側板の上端部を蓋体の係止部によって係止することができ、底板の係合部および短側板の係合部と相まって輸送時における側板のガタツキを確実に抑えることができる。   In the present invention, when the locking portion capable of locking the upper end portion of the side plate inserted along the inner surface of the long side plate is formed on the inner surface of the lid body, the upper opening is closed by the lid body When the article is transported, the upper end portion of the side plate erected along the inner surface of the long side plate can be locked by the locking portion of the lid, and the engaging portion of the bottom plate and the engaging portion of the short side plate In combination, the backlash of the side plate during transportation can be reliably suppressed.

本発明によれば、構造が簡単で安価に製造することができるとともに、ピッキング容器としても輸送容器としても使用することができる。   According to the present invention, the structure is simple and can be manufactured at low cost, and it can be used as a picking container and a transport container.

And the lower long side board 52 of each long side board 5 is connected with the baseplate 3 through the hinge pin and pin hole which are not illustrated of the hinge notch part 32a and the hinge bracket 52a, respectively, so that rotation is possible.

ここで、上枠体２の短辺枠材２１に対して短側板４をそれぞれ回動させ、その外面側下端部を立上片３２１に当接させるとともに、下端面を底板３の短辺側周縁部に支持した際、短側板４の内面が底板３の収容部３１の短辺側周縁の垂直面上に位置するように設定されている。また、上枠体２の長辺枠材２２に対して上部長側板５１を回動させるとともに、底板３における周縁部３２の長辺側周縁部に対して下部長側板５２を回動させ、上部長側板５１および下部長側板５２を伸展させて長側板５を底板３の長辺側周縁部に支持した際、長側板５の内面が底板３の収容部３１の長辺側周縁の垂直面上に位置するように設定されている。   Here, the short side plate 4 is rotated with respect to the short side frame member 21 of the upper frame body 2, the lower end portion of the outer surface side thereof is brought into contact with the rising piece 321, and the lower end surface is set on the short side side of the bottom plate 3. When supported on the peripheral edge, the inner surface of the short side plate 4 is set to be positioned on the vertical surface of the short side peripheral edge of the accommodating portion 31 of the bottom plate 3. Further, the upper long side plate 51 is rotated with respect to the long side frame member 22 of the upper frame 2, and the lower long side plate 52 is rotated with respect to the long side side peripheral portion of the peripheral portion 32 of the bottom plate 3. When the long side plate 5 and the lower long side plate 52 are extended to support the long side plate 5 on the long side peripheral edge of the bottom plate 3, the inner surface of the long side plate 5 is on the vertical plane of the long side peripheral edge of the housing portion 31 of the bottom plate 3. Is set to be located.

短側板４は、略浅い箱状に形成され、その上端部には、上枠体２の短辺枠材２１に形成されたヒンジブラケット２１ａに対応して複数個のヒンジ用切欠部４ａが形成され、該ヒンジ用切欠部４ａには、ヒンジピン４ｂが設けられている。そして、短側板４の内面側左右各端縁近傍には、図３に示すように、それぞれ係合部としての係合突起４ｘが上端近傍
から下端近傍にかけて連続して形成されている他、その外面側左右各端縁には、後述する長側板５の被嵌合リブ５ｂの厚みに相当する間隔をおいてそれぞれ嵌合リブ４ｃが外方に突出して形成されている。 The short side plate 4 is formed in a substantially shallow box shape, and a plurality of hinge cutouts 4a are formed at the upper end of the short side plate 4 corresponding to the hinge bracket 21a formed on the short side frame member 21 of the upper frame 2. The hinge notch 4a is provided with a hinge pin 4b. In addition, as shown in FIG. 3, engaging projections 4x as engaging portions are formed continuously from the vicinity of the upper end to the vicinity of the lower end, in the vicinity of the left and right edges on the inner surface side of the short side plate 4, On the left and right edges of the outer surface side, fitting ribs 4c are formed to protrude outwardly at intervals corresponding to the thickness of the fitted ribs 5b of the long side plate 5 described later.

長側板５は、上部長側板５１の下端部および下部長側板５２の上端部が折り畳み自在に連結されて構成され、上部長側板５１の上端部には、上枠体２の長辺枠材２２に形成されたヒンジ用切欠部２２ａに対応して複数個のヒンジブラケット５１ａが形成され、また、下部長側板５２の下端部には、底板３の長辺側周縁部に形成されたヒンジ用切欠部３２ａに対応して複数個のヒンジブラケット５２ａが形成されている。さらに、長側板５における上部長側板５１の内面側左右各端縁および下部長側板５２の内面側左右各端縁には、内方に向かって突出する断面Ｌ字状の被嵌合リブ５ｂ（図４参照）が形成されている。そして、長側板５を垂直状態に立設して、短側板４を回動した際、図４に示すように、長側板５の被嵌合リブ５ｂに短側板４の嵌合リブ４ｃが嵌合するように設定されている。   The long side plate 5 is configured such that the lower end portion of the upper long side plate 51 and the upper end portion of the lower long side plate 52 are foldably connected to each other, and the long side frame member 22 of the upper frame 2 is connected to the upper end portion of the upper long side plate 51. A plurality of hinge brackets 51a are formed corresponding to the hinge notches 22a formed on the bottom plate 3, and a hinge notch formed on the long side edge of the bottom plate 3 is formed at the lower end of the lower long plate 52. A plurality of hinge brackets 52a are formed corresponding to the portion 32a. Further, on the inner side of the long side plate 51 on the inner side of the upper long side plate 51 and on the left and right side of the inner side of the lower long side plate 52, the fitted ribs 5b having an L-shaped cross section projecting inwardly ( 4) is formed. Then, when the long side plate 5 is erected in a vertical state and the short side plate 4 is rotated, the fitting rib 4c of the short side plate 4 is fitted to the fitted rib 5b of the long side plate 5 as shown in FIG. Are set to match.

また、側板６は、対向する一対の短側板４の内面間隔に略相当する幅と、ほぼ底板３の収容部３１の表面から上枠体２の上面までの間隔に略相当する高さと、底板３の収容部３１の周縁から突起部３ｘの外縁までの間隔に略相当する厚みを有してほぼ方形状に形成され、その上端部近傍には、把手用孔６ａが形成されている（図１参照）。そして、側板６は、一方の長側板５の内面に沿う位置と、他方の長側板５の内面に沿う位置と、底板３の収容部３１の表面に載置する位置とに選択的に配置することができ、側板６を一方の長側板５の内面に沿って配置した際には、一方の長側板５の開口部５ａを閉鎖することができる。   Further, the side plate 6 has a width substantially corresponding to the inner surface interval of the pair of opposed short side plates 4, a height substantially corresponding to the interval from the surface of the accommodating portion 31 of the bottom plate 3 to the upper surface of the upper frame 2, and the bottom plate 3 is formed in a substantially rectangular shape with a thickness substantially corresponding to the distance from the peripheral edge of the accommodating portion 31 to the outer edge of the protruding portion 3x, and a handle hole 6a is formed in the vicinity of the upper end portion (see FIG. 1). The side plate 6 is selectively disposed at a position along the inner surface of one long side plate 5, a position along the inner surface of the other long side plate 5, and a position where the side plate 6 is placed on the surface of the accommodating portion 31 of the bottom plate 3. When the side plate 6 is disposed along the inner surface of the one long side plate 5, the opening 5a of the one long side plate 5 can be closed.

次に、このように構成された折り畳み容器１の使用方法を説明する。   Next, the usage method of the folding container 1 comprised in this way is demonstrated.

まず、図１に示した容器１の組み立て状態において、側板６を底板３の収容部３１の表面に載置した後（図１の一点鎖線状態）、対向する一対の短側板４の外面側下部を内方に向けて押し込み、上枠体２に対して各短側板４をそれぞれ跳ね上げる。この際、短側板４の下端面は、底板３の収容部３１の表面に載置された側板６の表面よりも若干上方に位置しているため、側板６に干渉することなく短側板４を回動させることができる。   First, in the assembled state of the container 1 shown in FIG. 1, after the side plate 6 is placed on the surface of the accommodating portion 31 of the bottom plate 3 (in the one-dot chain line state in FIG. 1), Is pushed inward, and each short side plate 4 is flipped up with respect to the upper frame 2. At this time, since the lower end surface of the short side plate 4 is located slightly above the surface of the side plate 6 placed on the surface of the accommodating portion 31 of the bottom plate 3, the short side plate 4 is not interfered with the side plate 6. It can be rotated.

短側板４を内方に跳ね上げた後、長側板５を構成する上部長側板５１および下部長側板５２の連結部を内方に向けて押し込めば、上枠体２と底板３との間において、各長側板５の上部長側板５１および下部長側板５２がそれぞれく字状に折曲して二つ折りされる。すなわち、上枠体２の長辺枠材２２に対して上部長側板５１が内方に回動するとともに、底板３の長辺側周縁部に対して下部長側板５２が内方に回動し、底板３の収容部３１に載置された側板６の上に二つ折りされた上部長側板５１および下部長側板５２が積み重ねられて収納され、さらに、底板３の周縁部３２に上枠体２が積み重ねられることから、図５に示すように、小さな容積に折り畳むことができる。この際、上枠体２によって区画された内方において、二つ折りされた長側板５の上に短側板４がそれぞれ積み重ねられる。   After the short side plate 4 is flipped inward, if the connecting portion of the upper long side plate 51 and the lower long side plate 52 constituting the long side plate 5 is pushed inward, between the upper frame 2 and the bottom plate 3 The upper long side plate 51 and the lower long side plate 52 of each long side plate 5 are bent in a square shape and folded in half. That is, the upper long side plate 51 rotates inward with respect to the long side frame member 22 of the upper frame 2, and the lower long side plate 52 rotates inward with respect to the long side side peripheral portion of the bottom plate 3. The upper long side plate 51 and the lower long side plate 52 which are folded in two on the side plate 6 placed on the receiving portion 31 of the bottom plate 3 are stacked and stored, and further, the upper frame body 2 is mounted on the peripheral portion 32 of the bottom plate 3. Can be folded into a small volume as shown in FIG. At this time, the short side plates 4 are stacked on the long side plate 5 folded in half on the inner side defined by the upper frame body 2.

一方、折り畳み容器１を使用する場合は、図５に示す折り畳み状態から、上枠体２を把握して上方に持ち上げれば、上枠体２に連結された長側板５の上部長側板５１が追従して引き上げられる。そして、上部長側板５１に連結された下部長側板５２も上部長側板５１に対して回動角度を徐々に大きくなるように伸展し、追従して引き上げられる。この際、短側板４を支えていた長側板５が伸展するため、短側板４は自重で下方に回動する。この後、各短側板４の下部内面側を外方に向けて押圧すれば、その下端面が底板３の短辺側周縁部に乗り上げるとともに、外面側下端部が立上片３２１に当接することから、その内面が垂直面を形成するように立設することができる。そして、短側板４が回動にすることにより、その左右側端面が長側板５の内面を支持して長側板５が屈曲することを規制すると
ともに、長側板５の上部長側板５１の左右各端縁および下部長側板５２の左右各端縁にそれぞれ形成された被嵌合リブ５ｂに短側板４の嵌合リブ４ｃが嵌合し、上枠体２に対する短側板４の跳ね上がりを、底板３の短辺側周縁部に対する短側板４の下端面の嵌合による摩擦抵抗とともに、長側板５の被嵌合リブ５ｂに対する短側板４の嵌合リブ４ｃの嵌合による摩擦抵抗によって防止することができる。 On the other hand, when the folding container 1 is used, if the upper frame 2 is grasped and lifted upward from the folded state shown in FIG. 5, the upper long side plate 51 of the long side plate 5 connected to the upper frame 2 is Followed up. The lower long side plate 52 connected to the upper long side plate 51 also extends so as to gradually increase the rotation angle with respect to the upper long side plate 51, and is pulled up following. At this time, since the long side plate 5 supporting the short side plate 4 extends, the short side plate 4 rotates downward by its own weight. Thereafter, when the lower inner surface side of each short side plate 4 is pressed outward, its lower end surface rides on the short side peripheral portion of the bottom plate 3, and the outer surface lower end portion comes into contact with the rising piece 321. Thus, the inner surface can be erected so as to form a vertical surface. Then, by turning the short side plate 4, the left and right side end surfaces support the inner surface of the long side plate 5 and restrict the bending of the long side plate 5, and the left and right sides of the upper long side plate 51 of the long side plate 5. The fitting ribs 4c of the short side plate 4 are fitted to the fitting ribs 5b formed on the left and right edges of the end edge and the lower long side plate 52, respectively, and the bottom plate 3 In addition to frictional resistance due to fitting of the lower end surface of the short side plate 4 to the peripheral edge of the short side, the frictional resistance due to fitting of the fitting rib 4c of the short side plate 4 to the rib 5b of the long side plate 5 can be prevented. it can.

容器１が組み立てられたならば、一方の長側板５の内面に沿って側板６を差し込めば、その左右各端縁および下端縁が短側板４の係合突起４ｘおよび底板３の係合突起３ｘに係合することから、側板６は、倒れが規制されて立設状態に保持される。したがって、一方の長側板５の開口部５ａを側板６によって閉鎖することができる。   When the container 1 is assembled, if the side plate 6 is inserted along the inner surface of one long side plate 5, its left and right end edges and lower end edge are the engagement projections 4x of the short side plate 4 and the engagement projections 3x of the bottom plate 3. Therefore, the side plate 6 is held in an upright state with the falling of the side plate 6 regulated. Therefore, the opening 5 a of one long side plate 5 can be closed by the side plate 6.

したがって、容器１の上方開口部を通して内部に物品を収容することができ、物品を収容した容器１を積み重ねて保管し、あるいは、輸送することができる（図６参照）。この際、側板６の左右各端面は、短側板４の内面に当接しており、短側板４の跳ね上がりを規制することができることから、短側板４の意図しない跳ね上げによって積み重ねた容器１の荷崩れを確実に防止することができる。   Therefore, articles can be accommodated inside through the upper opening of the container 1, and the containers 1 containing articles can be stacked and stored or transported (see FIG. 6). At this time, since the left and right end surfaces of the side plate 6 are in contact with the inner surface of the short side plate 4 and the jumping of the short side plate 4 can be restricted, the load of the container 1 stacked by unintentional jumping of the short side plate 4 is avoided. Breakage can be reliably prevented.

一方、物品を目的地まで輸送した後、側板６を引き上げれば、一方の長側板５の開口部５ａを開放することができることから、その後、容器１を積み重ねた状態で、開放された開口部５ａを通して物品を取り出すことができる（図７参照）。この場合、一方の長側板５に沿って引き上げた側板６については、他方の長側板５の内面に沿って同様に差し込むことにより、底板３の係合突起３ｘおよび短側板４の係合突起４ｘによって立設状態に保持することができることから、側板６の紛失を防止することができる。また、側板６の左右各端面が短側板４の内面に当接して、短側板４の跳ね上がりを規制できることから、短側板４の意図しない跳ね上げによって積み重ねた容器１が荷崩れするのを確実に防止することができる。   On the other hand, if the side plate 6 is pulled up after the article is transported to the destination, the opening 5a of the one long side plate 5 can be opened, and then the opened opening in the state where the containers 1 are stacked. The article can be taken out through 5a (see FIG. 7). In this case, the side plate 6 pulled up along the one long side plate 5 is inserted in the same manner along the inner surface of the other long side plate 5, thereby engaging the engagement projection 3 x of the bottom plate 3 and the engagement projection 4 x of the short side plate 4. Therefore, it is possible to prevent the side plate 6 from being lost. In addition, since the left and right end surfaces of the side plate 6 abut against the inner surface of the short side plate 4 and the short side plate 4 can be prevented from jumping up, it is ensured that the stacked containers 1 collapse due to unintentional jumping of the short side plate 4. Can be prevented.

なお、物品の取り出しが終了して容器１を回収する場合は、前述したように、側板６を底板３の収容部３１の表面に載置した後、一対の短側板４の外面側下部を内方に向けて押し込んで上枠体２に対して各短側板４をそれぞれ跳ね上げ、次いで、長側板５を構成する上部長側板５１および下部長側板５２の連結部を内方に向けて押し込めば、上枠体２と底板３との間において、各長側板５の上部長側板５１および下部長側板５２がそれぞれく字状に折曲して二つ折りされ、側板６の上に積み重ねられるとともに、その上に短側板４がそれぞれ積み重ねられ、さらに、底板３の周縁部３２に上枠体２が積み重ねられて折り畳むことができる（図５参照）。   When the container 1 is collected after the article has been taken out, as described above, after placing the side plate 6 on the surface of the accommodating portion 31 of the bottom plate 3, the lower portions on the outer surface side of the pair of short side plates 4 are placed inside. If the short side plate 4 is pushed up toward the upper frame 2 and then the short side plate 4 is flipped up, and then the connecting portion of the upper long side plate 51 and the lower long side plate 52 constituting the long side plate 5 is pushed inward. The upper long side plate 51 and the lower long side plate 52 of each long side plate 5 are bent in a square shape and folded in half between the upper frame 2 and the bottom plate 3 and stacked on the side plate 6. Further, the short side plates 4 are stacked, and the upper frame 2 can be stacked and folded on the peripheral edge 32 of the bottom plate 3 (see FIG. 5).

したがって、空の容器１を回収する場合は、容積を小さくして輸送することができ、輸送効率を向上させることができる。   Therefore, when recovering the empty container 1, the volume can be reduced and transported, and transport efficiency can be improved.

ところで、図８および図９には、本発明の折り畳み容器１の他の実施形態が記載されている。   By the way, other embodiment of the folding container 1 of this invention is described by FIG. 8 and FIG.

この折り畳み容器１は、先に説明した折り畳み容器１にその上方開口部を開閉可能な蓋体７をさらに設けて構成されている。   The folding container 1 is configured by further providing a lid 7 that can open and close the upper opening of the folding container 1 described above.

すなわち、容器１を構成する上枠体２における各長辺枠材２２の上端部には、それぞれ複数個のヒンジブラケット２２ｂが形成されており、このヒンジブラケット２２ｂのピン孔（図示せず）に対してそれぞれ蓋体７がヒンジピン７ａを介して回動自在に連結されている。   That is, a plurality of hinge brackets 22b are formed at the upper ends of the long-side frame members 22 in the upper frame 2 constituting the container 1, and pin holes (not shown) of the hinge brackets 22b are formed. On the other hand, the lid body 7 is rotatably connected via a hinge pin 7a.

なお、蓋体７の内面には、底板３の係合突起３ｘおよび短側板４の係合突起４ｘによって長側板５の内面に沿って立設状態に保持された側板６の上端部を係止可能な係止部としての係止片７ｘが形成されており、蓋体７を回動して容器１の上方開口部を閉鎖した際、側板６の上端部を係止片７ｘによって係止することができ、容器１の輸送時において、側板６のガタツキを確実に防止することができる。   In addition, the upper end portion of the side plate 6 held upright along the inner surface of the long side plate 5 by the engagement projection 3x of the bottom plate 3 and the engagement projection 4x of the short side plate 4 is locked to the inner surface of the lid body 7. A locking piece 7x is formed as a possible locking portion. When the lid 7 is rotated to close the upper opening of the container 1, the upper end of the side plate 6 is locked by the locking piece 7x. It is possible to reliably prevent the side plate 6 from rattling when the container 1 is transported.

また、上枠体２における各短辺枠材２１の上端部には、それぞれ複数個のスタック用突起２１ｂが形成されており、前述した各長辺枠材２２の上端部に形成されたヒンジブラケット２２ｂと合わせて、容器１を積み重ねた際の容器１の脱落を防止することができるものである。具体的には、底板３の外面には、各短辺枠材２１のスタック用突起２１ｂおよび各長辺枠材２２のヒンジブラケット２２ｂの内面によって区画される方形に対応する外周面を有するリブ３ａ（図９参照）が垂設されており、容器１を上下に積み重ねた際、底板３のリブ３ａの外面に、各短辺枠材２１のスタック用突起２１ｂおよび各長辺枠材２２のヒンジブラケット２２ｂの内面がそれぞれ位置するとともに、その上面に上方の容器１の底板３の外面側周縁部が載置されるように設定されている。   Further, a plurality of stacking projections 21b are formed at the upper end of each short side frame member 21 in the upper frame 2, and the hinge bracket formed at the upper end of each long side frame member 22 described above. Together with 22b, the container 1 can be prevented from falling off when the containers 1 are stacked. Specifically, on the outer surface of the bottom plate 3, a rib 3a having an outer peripheral surface corresponding to a square defined by the stack projections 21b of the short side frame members 21 and the inner surface of the hinge bracket 22b of the long side frame members 22 is provided. (See FIG. 9) is vertically provided, and when the containers 1 are stacked up and down, the stack projections 21b of the short side frame members 21 and the hinges of the long side frame members 22 are formed on the outer surfaces of the ribs 3a of the bottom plate 3. Each of the inner surfaces of the brackets 22b is positioned, and the outer peripheral side peripheral portion of the bottom plate 3 of the upper container 1 is set on the upper surface thereof.

したがって、一方の長側板５の開口部５ａを側板６によって閉鎖する一方、物品を内部に収容した後、容器１の上方開口部を蓋体７によって閉鎖した状態で、積み重ねて目的地に向けて輸送し、あるいは、保管することができる（図１０参照）。この場合、詳細には図示しないが、蓋体７を上枠体２に対して封緘することにより、短側板４の跳ね上げが側板６によって規制されることと相まって、開口部が存在せず、物品の盗難を回避することができ、防犯上好ましい。   Accordingly, the opening 5a of one long side plate 5 is closed by the side plate 6, while the article is accommodated in the inside, and then the upper opening of the container 1 is closed by the lid body 7 and is stacked toward the destination. It can be transported or stored (see FIG. 10). In this case, although not shown in detail, there is no opening by combining the lid body 7 with the upper frame body 2, and the flipping of the short side plate 4 is restricted by the side plate 6, Theft of goods can be avoided, which is preferable for crime prevention.

また、物品を目的地まで輸送した後、側板６を引き上げれば、一方の長側板５の開口部５ａを開放することができ、開放された開口部５ａを通して物品を取り出すことができる（図１１参照）。この際、側板６は、他方の長側板５の内面に沿って差し込んで、保持すればよい。   Further, if the side plate 6 is pulled up after the article is transported to the destination, the opening 5a of one long side plate 5 can be opened, and the article can be taken out through the opened opening 5a (FIG. 11). reference). At this time, the side plate 6 may be inserted and held along the inner surface of the other long side plate 5.

なお、詳細には図示しないが、空容器１を回収する場合は、折り畳んで輸送する点は同様である。   Although not shown in detail, when collecting the empty container 1, it is the same in that it is folded and transported.

以上のように本発明によれば、容器を組み立てて物品を収容し、積み重ねた状態で保管や輸送を行うことができるとともに、開口部を通して物品を取り出すことができることから、折り畳み容器を多目的に活用することが可能となる。しかも、簡単な構成を付加するのみでよく、折り畳み容器を安価に提供することができる。   As described above, according to the present invention, containers can be assembled to store articles, stored and transported in a stacked state, and articles can be taken out through the opening. It becomes possible to do. Moreover, it is only necessary to add a simple configuration, and the folding container can be provided at a low cost.
