Description

本発明は、ワークの運搬等に使用される箱型容器に関するものである。 The present invention relates to a box-type container used for transporting workpieces and the like.

一般に、ワークの運搬等に使用される箱型容器は、底壁構成部と、底壁構成部の外周縁から上方に延出する周壁部とを備えており、上方の開口部から物品を出し入れする構成となっている。また、箱型容器には、内部に収容した所定形状のワークを所定の姿勢で保持可能に構成されるとともに、ワークを収容した状態にある複数の箱型容器を段積みする（スタッキングする）ことができるように構成されたものがある（例えば、特許文献１等参照。）。 In general, a box-type container used for transporting a workpiece has a bottom wall constituent part and a peripheral wall part extending upward from the outer peripheral edge of the bottom wall constituent part, and an article is taken in and out from the upper opening part. It is the composition to do. In addition, the box-shaped container is configured to be able to hold a workpiece having a predetermined shape housed in a predetermined posture, and stacking (stacking) a plurality of box-shaped containers in which the workpiece is housed. (For example, refer patent document 1 etc.).

ところで、収容されるワークの形状によっては、箱型容器の内側に形成される収容空間を有効利用することができずに、デッドスペースが比較的大きく形成されてしまう場合がある。この場合、ワークの運搬・保管に箱型容器を使用することによって、所定数のワークを運搬・保管するためのスペースが比較的大きくなってしまうおそれがある。従って、箱型容器の内側の収容空間にほぼ隙間なくワークが収容される場合等に比べ、ワークの運搬効率、保管効率の悪化を招くことが懸念され、特に、箱型容器をスタッキングする場合には、かかる不具合がより顕著なものとなる。 By the way, depending on the shape of the workpiece to be accommodated, the accommodation space formed inside the box-shaped container cannot be effectively used, and the dead space may be formed relatively large. In this case, the use of a box-type container for transporting and storing workpieces may cause a relatively large space for transporting and storing a predetermined number of workpieces. Therefore, there is a concern that the work transportation efficiency and storage efficiency will be deteriorated compared to the case where the work is accommodated in the accommodation space inside the box-shaped container with almost no gap, especially when stacking the box-shaped container. In such a case, such a defect becomes more prominent.

本発明は上記問題点等を解決するためになされたものであって、その目的は、スタッキング状態におけるコンパクト化を図ることのできる箱型容器を提供することにある。 The present invention has been made to solve the above-described problems, and an object thereof is to provide a box-type container that can be made compact in a stacking state.

以下、上記目的等を解決するのに適した各手段につき項分けして説明する。なお、必要に応じて対応する手段に特有の作用効果等を付記する。 In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

手段１．略直線状に延在する直線部と、前記直線部の一端部又はその近傍から交差する方向に突出する突出部とを備えるワークを、前記突出部が下方に突出する姿勢で収容可能に構成されるとともに、
底壁構成部と、前記底壁構成部の外周縁から上方に延出する周壁部とを備え、
同じ向きで上下に重ねることでネスティングが行え、交互に１８０度回転させて上下に重ねることでスタッキングが行える箱型容器において、
前記ワークの前記突出部を収容可能な突部収容部と、前記突出部が前記突部収容部に収容された状態の前記ワークの前記直線部を支持可能な直線支持部とを備え、
前記突部収容部は、前記底壁構成部から下方に突出する収納用凸部の内側に形成され、
前記ワークが前記直線支持部によって支持されることで、前記直線部が前記突部収容部から遠ざかる方向に向けて下方傾斜するとともに、
前記箱型容器のスタッキング状態において、下側の箱型容器に収容された前記ワークの前記直線部のうち下方傾斜した先端部の上方に、上側の箱型容器の前記収納用凸部が近接配置されるようにしたことを特徴とする箱型容器。 Means 1. A workpiece including a linear portion extending substantially linearly and a protruding portion protruding in a direction intersecting from one end portion of the linear portion or the vicinity thereof is configured to be accommodated in a posture in which the protruding portion protrudes downward. And
A bottom wall constituent part, and a peripheral wall part extending upward from the outer peripheral edge of the bottom wall constituent part,
In a box-type container that can be nested by stacking up and down in the same direction, and can be stacked by rotating 180 degrees alternately and stacking up and down,
A protrusion accommodating portion capable of accommodating the protruding portion of the workpiece; and a linear support portion capable of supporting the linear portion of the workpiece in a state where the protruding portion is accommodated in the protruding portion accommodating portion,
The protrusion accommodating portion is formed on the inner side of the storing convex portion protruding downward from the bottom wall constituting portion,
As the workpiece is supported by the linear support portion, the linear portion is inclined downward in a direction away from the protrusion accommodating portion, and
In the stacking state of the box-shaped container, the storage convex part of the upper box-shaped container is arranged close to the upper part of the linearly inclined portion of the work housed in the lower box-shaped container. A box-type container characterized by being made.

手段１によれば、直線部と、直線部から交差する方向に突出する突出部とを具備するワークは、突出部が下向きに突出するような姿勢で箱型容器に収容される。このため、箱型容器の外周長（外寸）を極力小さくすることができる。さらに、ワークを収容した状態の複数の箱型容器を段積みする（スタッキングする）ことができるように構成されているため、運搬効率や保管効率の向上を図ることができる。 According to the means 1, the workpiece including the straight portion and the protruding portion protruding in the direction intersecting with the straight portion is accommodated in the box-type container in such a posture that the protruding portion protrudes downward. For this reason, the outer peripheral length (outside dimension) of the box-shaped container can be made as small as possible. Furthermore, since it is comprised so that the several box-shaped container in the state which accommodated the workpiece | work can be stacked (stacked), the improvement of conveyance efficiency and storage efficiency can be aimed at.

また、箱型容器には、突出部を収容可能とする突部収容部を形成するべく、底壁構成部から下方に突出する収納用凸部が形成されている。さらに、箱型容器に収容されたワークの直線部は、突出部が設けられていない側の先端部に向けて下方傾斜している。このため、箱型容器をスタッキングさせた場合に、直線部が傾斜していることによって前記先端部の位置が下げられた分だけ、その上方に確保することのできた収容空間に対して、上側の箱型容器の収納用凸部を進入させることができる。従って、複数の箱型容器を上下に極力詰めてスタッキングすることができ、スタッキング状態におけるコンパクト化を図ることができる。 In addition, the box-shaped container is formed with a storage convex portion that protrudes downward from the bottom wall constituting portion so as to form a protrusion accommodating portion that can accommodate the protruding portion. Furthermore, the linear part of the workpiece accommodated in the box-shaped container is inclined downward toward the tip part on the side where the protruding part is not provided. For this reason, when the box-shaped container is stacked, the upper portion of the storage space that can be secured above the amount corresponding to the lowered position of the tip portion due to the inclination of the linear portion is The convex part for storage of a box-shaped container can be made to approach. Accordingly, it is possible to stack a plurality of box-shaped containers as much as possible in the vertical direction, and to achieve compactness in the stacking state.

また、複数の箱型容器を交互に１８０度回転させて積み重ねることでスタッキングされるため、下側の箱型容器に収容されたワークと、上側の箱型容器に収容されたワークとが、互いに１８０度回転した向きで、上側の箱型容器の底壁構成部を介して、相対配置されることとなる。このため、スタッキングされた複数の箱型容器からなる積物の荷重の偏りを抑制でき、積物の倒壊等のおそれを防止することができる。 In addition, since the plurality of box-type containers are stacked by alternately rotating 180 degrees, the work housed in the lower box-type container and the work housed in the upper box-type container are mutually connected. In the direction rotated by 180 degrees, they are arranged relative to each other via the bottom wall constituting portion of the upper box-shaped container. For this reason, it is possible to suppress the uneven load of the product composed of the plurality of stacked box-type containers, and to prevent the possibility of collapse of the product.

手段２．前記周壁部を部分的に外周側に膨出させるようにして形成され、スタッキング状態において下側の箱型容器に当接して支持される支脚部を備え、
前記周壁部は相対する一対の側壁部を２組備えるとともに、そのうち１組の相対する一対の前記側壁部において、前記支脚部が相対する位置に形成されていることを特徴とする手段１に記載の箱型容器。 Mean 2. The peripheral wall portion is formed so as to partially bulge to the outer peripheral side, and includes a support leg portion supported in contact with the lower box-shaped container in a stacking state,
The said peripheral wall part is provided with two sets of a pair of opposite side wall parts, The said support leg part is formed in the position which the said pair of side wall parts of one set of which face each other opposes. Box container.

手段２によれば、全ての側壁部に支脚部を設ける場合に比べ、箱型容器の外寸を小さく構成することができる。また、本手段２によれば、相対する側壁部のうち一方の側壁部に形成された支脚部と他方の側壁部に形成された支脚部とが互いに相対する位置に形成されている（１つの側壁部に複数の支脚部が形成される場合には一対の側壁部の支脚部の形成ピッチが同じ）。このため、スタッキング状態において、支脚部が形成された一対の側壁部のうちの一方側と他方側とで支持バランスが比較的大きく異なってしまうといった事態を回避することができ、段積み状態の安定化を図ることができる。 According to the means 2, the outer dimensions of the box-type container can be made smaller than in the case where the supporting leg portions are provided on all the side wall portions. Further, according to the present means 2, the supporting leg portion formed on one of the opposing side wall portions and the supporting leg portion formed on the other side wall portion are formed at positions facing each other (one When a plurality of support legs are formed on the side walls, the formation pitch of the support legs of the pair of side walls is the same). For this reason, in the stacking state, it is possible to avoid a situation in which the support balance is relatively different between one side and the other side of the pair of side wall portions on which the support legs are formed, and the stacked state is stable. Can be achieved.

手段３．前記周壁部は、相対する一対の長辺側側壁部と、前記一対の長辺側側壁部の側縁部間を連結するとともに、前記一対の長辺側側壁部間の距離よりも大きく離間して相対する一対の短辺側側壁部とから構成され、前記支脚部は一対の前記長辺側側壁部に形成されていることを特徴とする手段２に記載の箱型容器。 Means 3. The peripheral wall portion connects between the pair of opposed long side wall portions and the side edges of the pair of long side wall portions, and is spaced apart from the distance between the pair of long side wall portions.

手段３によれば、長辺側側壁部及び短辺側側壁部のうち横幅が長い方の長辺側側壁部に支脚部が形成されているため、支脚部の形成ピッチを極力大きくすることができ、スタッキング状態の安定化を図ることができる。 According to the means 3, since the supporting leg part is formed on the long side wall part of the longer side of the long side wall part and the short side wall part, the formation pitch of the supporting leg part can be increased as much as possible. It is possible to stabilize the stacking state.

手段４．複数の前記ワークを前記直線部が互いに平行となるようにして横並びで収容可能に構成され、
前記周壁部を構成する側壁部のうち、前記ワークの前記直線部の長手方向に沿って延在する前記側壁部において前記支脚部が形成されるとともに、
前記ワークの前記直線部の両端部に対向する前記側壁部の内側面が平坦面となっていることを特徴とする手段２又は３に記載の箱型容器。 Means 4. A plurality of the workpieces are configured to be accommodated side by side so that the linear portions are parallel to each other,
Among the side wall parts constituting the peripheral wall part, the support leg part is formed in the side wall part extending along the longitudinal direction of the linear part of the workpiece,
The box-shaped container according to means 2 or 3, wherein an inner surface of the side wall portion facing both ends of the linear portion of the workpiece is a flat surface.

手段４によれば、複数のワークの端部に対向する側壁部の内側面には凹凸がほぼ皆無であることから、各ワークがその長手方向において位置ずれしそうになった場合でも、かかる側壁部によって各ワークの端部を安定して支持することができ、位置ずれを確実に防止することができる。また、ワークを収容する際にワークの端部が側壁部に引っ掛かるといった事態を防止することができ、収容作業性を向上させることができる。さらに、直線部に沿って延びる側壁部に関しては、それぞれ１つのワークに隣接するだけなので、当該側壁部においては、隣接する１つのワークのガタツキを防止する構成を設けるだけで済む。このため、ワークのガタツキを防止する構成及び支脚部を設けるスペースを十分に確保することができ、ワークのガタツキを招くことなく、支脚部を設けることができる。 According to the means 4, since there are almost no irregularities on the inner surface of the side wall portion facing the ends of the plurality of workpieces, even if each workpiece is likely to be displaced in the longitudinal direction, the side wall portion Thus, the end portion of each workpiece can be stably supported, and displacement can be reliably prevented. Moreover, the situation that the edge part of a workpiece | work is caught by a side wall part can be prevented when accommodating a workpiece | work, and accommodation workability | operativity can be improved. Furthermore, since the side wall portions extending along the straight line portion are each adjacent to only one workpiece, it is only necessary to provide a configuration that prevents rattling of one adjacent workpiece in the side wall portion. For this reason, the structure which prevents the backlash of a workpiece | work, and the space which provides a support leg part can fully be ensured, and a support leg part can be provided, without causing the backlash of a workpiece | work.

手段５．前記支脚部が形成された前記側壁部には、前記周壁部の外周方向に膨出し、前記箱型容器に収容された前記ワークの前記直線部の側方から当該直線部の下方に手を差し込むことを許容する挿入凹部が形成されていることを特徴とする手段４に記載の箱型容器。 Means 5. The side wall portion on which the support leg portion is formed bulges in the outer peripheral direction of the peripheral wall portion, and inserts a hand below the straight portion from the side of the straight portion of the workpiece accommodated in the box-shaped container. The box-shaped container according to the means 4, wherein an insertion concave portion that allows this is formed.

手段５によれば、挿入凹部が形成されることで、箱型容器に収容されているワークを取出す際に、挿入凹部に手を差し入れて直線部の下側に手を掛けることができる。また、ワークを箱型容器に収容する際に、ワークが直線支持部に支持されるまでワークの下側を手で支持しておくことができる。従って、ワークを箱型容器に収容したり、ワークを箱型容器から取外したりする際の作業性の向上を図ることができる。さらに、支脚部が形成された側壁部に対して挿入凹部が形成されているため、支脚部が形成されていない側壁部に対して別途周壁部の外周側に膨出する挿入凹部を形成する場合に比べ、箱型容器の外寸を極力小さくすることができ、箱型容器の大型化を抑制することができる。 According to the means 5, when the insertion concave portion is formed, when taking out the work housed in the box-shaped container, it is possible to insert a hand into the insertion concave portion and put a hand under the straight portion. Moreover, when accommodating a workpiece | work in a box-type container, the lower side of a workpiece | work can be supported by hand until a workpiece | work is supported by the linear support part. Accordingly, it is possible to improve workability when the work is accommodated in the box-shaped container or the work is removed from the box-shaped container. In addition, since the insertion recess is formed in the side wall portion where the support leg portion is formed, the insertion recess that bulges to the outer peripheral side of the peripheral wall portion separately from the side wall portion where the support leg portion is not formed. In comparison with the above, the outer size of the box-type container can be made as small as possible, and the increase in size of the box-type container can be suppressed.

さて、本実施形態の箱型容器１は、図３に示すように、直線状に延びる直線部２２と、直線部２２の一端部から直交する方向に突出する突出部２３とを備えて略Ｌ字状をなすワーク２１の運搬等に使用される。図４、図５に示すように、本実施形態では、ワーク２１は、突出部２３が下方に突出するような姿勢で箱型容器１に収容可能に構成されている。また、本実施形態では、１つの箱型容器１に対して４つのワーク２１を収容可能に構成されており、各ワーク２１の直線部２２が箱型容器１の長手方向に沿って延在するとともに、４つのワーク２１の直線部２２が互いに平行となるようにして横並びで収容可能に構成されている。さらに、詳しくは後述するが、箱型容器１に収容されたワーク２１は、全て同じ姿勢の同じ向きで同じ高さとなるように保持されている。 Now, as shown in FIG. 3, the box-shaped container 1 of the present embodiment includes a linear portion 22 that extends linearly and a protruding portion 23 that protrudes in a direction orthogonal to one end of the linear portion 22. It is used for transporting a workpiece 21 having a character shape. As shown in FIGS. 4 and 5, in the present embodiment, the workpiece 21 is configured to be accommodated in the box-type container 1 in such a posture that the protruding portion 23 protrudes downward. Moreover, in this embodiment, it is comprised so that the four workpiece | work 21 can be accommodated with respect to one box-type container 1, and the linear part 22 of each workpiece | work 21 extends along the longitudinal direction of the box-type container 1. FIG. In addition, the linear portions 22 of the four workpieces 21 are configured to be accommodated side by side so as to be parallel to each other. Furthermore, although mentioned later in detail, the workpiece | work 21 accommodated in the box-type container 1 is hold | maintained so that it may become the same height with the same direction of all the attitude | positions.

本実施形態では、Ｌ字状のワーク２１を上記のような姿勢で保持するための構成に特徴があるため、以下、かかる構成を中心に説明する。尚、以下の説明では、便宜上、直線部２２のうち突出部２３が形成された側の端部を「基端部２５」と称し、他方の端部を「先端部２６」と称する。 In the present embodiment, since the configuration for holding the L-shaped workpiece 21 in the above-described posture is characteristic, the configuration will be mainly described below. In the following description, for convenience, the end of the straight portion 22 on the side where the protruding portion 23 is formed is referred to as a “base end portion 25”, and the other end is referred to as a “tip portion 26”.

図１、図８等に示すように、箱型容器１には、第１短辺側側壁部７ａの内側面に沿って設けられ、ワーク２１の突出部２３を収容可能な突部収容部３２と、ワーク２１の直線部２２を支持可能な直線支持部３５とが設けられている。 As shown in FIGS. 1, 8, and the like, the box-shaped container 1 is provided along the inner surface of the first short side wall 7 a and can accommodate the protrusion 23 of the workpiece 21. And the linear support part 35 which can support the linear part 22 of the workpiece | work 21 is provided.

図２に示すように、相対する一対の第１支脚部１１ａの間には、底壁構成部２から下方に膨出する収納用凸部３１が設けられている。そして、図１、図５に示すように、当該収納用凸部３１が上方に開口する中空状に構成されていることで、収納用凸部３１の内側面により突部収容部３２が形成されている。図２に示すように、本実施形態では、収納用凸部３１の下端部と支脚部１１の下端部との高さ位置が揃うように（仮想の同一平面上に位置するように）構成されている。また、図１に示すように、突部収容部３２には、箱型容器１に収容された各ワーク２１の突出部２３の両側方において、突部収容部３２の底面から上方に突出し、ワーク２１の突出部２３の回動変位を規制する回動規制凸部３３が形成されている。これにより、突出部２３が下方を向いたワーク２１の姿勢が保持されることとなる。 As shown in FIG. 2, a storage convex portion 31 that bulges downward from the bottom wall constituting portion 2 is provided between the pair of opposing first support legs 11 a. As shown in FIG. 1 and FIG. 5, the convex portion 31 is formed by the inner side surface of the convex portion 31 for storage because the convex portion 31 for storage is formed in a hollow shape that opens upward. ing. As shown in FIG. 2, in this embodiment, it is comprised so that the height position of the lower end part of the convex part 31 for storage and the lower end part of the support leg part 11 may align (it is located on the virtual same plane). ing. Further, as shown in FIG. 1, the protrusion accommodating portion 32 protrudes upward from the bottom surface of the protrusion accommodating portion 32 on both sides of the protruding portion 23 of each workpiece 21 accommodated in the box-shaped container 1. A rotation restricting convex portion 33 for restricting the rotational displacement of the protruding portion 23 of 21 is formed. As a result, the posture of the work 21 with the protruding portion 23 facing downward is maintained.

また、直線支持部３５は、突部収容部３２に隣接して、相対する一対の第２脚受部１２ｂの間に設けられ、直線部２２のうち突出部２３側の部位（基端部２５）を支持する基端側保持部３６と、第２短辺側側壁部７ｂの内側面に隣接して設けられ、直線部２２のうちの突出部２３が設けられていない側の部位（先端部２６）を支持する先端側保持部３７とを備えている。 Further, the linear support portion 35 is provided between the pair of opposing second leg receiving portions 12 b adjacent to the protrusion accommodating portion 32, and a portion (base end portion 25) on the protruding portion 23 side of the linear portion 22. ) Supporting the base end side holding portion 36 and the inner side surface of the second short side wall portion 7b, and the portion of the straight portion 22 on the side where the projecting portion 23 is not provided (tip portion) 26) and a front-end side holding portion 37 that supports (26).

図５に示すように、本実施形態では、ワーク２１の突出部２３が突部収容部３２に収容されるとともに、直線部２２が直線支持部３５によって支持されることにより、直線部２２が突部収容部３２から遠ざかる方向に向けて下方傾斜するように構成されている。従って、先端部２６の上縁部は、基端部２５の上縁部よりも下方に位置しており、先端部２６から箱型容器１の上縁部（張り出し部４の上面）までの距離は、基端部２５から箱型容器１の上縁部までの距離よりも長くなっている。但し、先端側保持部３７は突部収容部３２の底面よりも上方に位置している。このため、直線部２２の下端部となる先端部２６の下縁部は、突出部２３の下端部よりも上方に位置している。 As shown in FIG. 5, in this embodiment, the projecting portion 23 of the work 21 is accommodated in the projecting portion accommodating portion 32, and the linear portion 22 is supported by the linear support portion 35. It is comprised so that it may incline below toward the direction away from the part accommodating part 32. As shown in FIG. Accordingly, the upper edge portion of the distal end portion 26 is positioned below the upper edge portion of the base end portion 25, and the distance from the distal end portion 26 to the upper edge portion of the box-type container 1 (the upper surface of the overhang portion 4). Is longer than the distance from the base end 25 to the upper edge of the box-shaped container 1. However, the distal end side holding portion 37 is positioned above the bottom surface of the protrusion accommodating portion 32. For this reason, the lower edge part of the front-end | tip part 26 used as the lower end part of the linear part 22 is located above the lower end part of the protrusion part 23. FIG.

尚、直線支持部３５のうち直線部２２の下側面に当接して支持する部位は、直線部２２の長手方向に沿って複数個所存在するが、突部収容部３２から離間する部位ほど下方に位置することとなる。例えば、先端側保持部３７としては、直線部２２の先端部２６の端末分を支持する部位と、端末部分から若干離間した部位を支持する部位とが存在し、前者は後者よりも下方に位置する上、直線部２２の長手方向においてある程度の長さを有する前者については、その支持面が第２短辺側側壁部７ｂに向けて下方傾斜している。 Note that there are a plurality of portions of the linear support portion 35 that abut on and support the lower surface of the linear portion 22 along the longitudinal direction of the linear portion 22. Will be located. For example, as the distal end side holding portion 37, there are a portion that supports the terminal portion of the distal end portion 26 of the linear portion 22 and a portion that supports a portion slightly separated from the terminal portion, and the former is positioned below the latter. In addition, the support surface of the former having a certain length in the longitudinal direction of the linear portion 22 is inclined downward toward the second short side wall portion 7b.

また、上記のように、第１脚受部１２ａ及び第２脚受部１２ｂの各支持壁部１３の高さ位置は揃っているのではあるが、本実施形態では、直線部２２が傾いた状態でワーク２１が箱型容器１に収容されるため、各脚受部１２ａ、１２ｂの支持壁部１３とワーク２１との上下方向における相対位置関係が変化している。すなわち、図５に示すように、ワーク２１の直線部２２のうち第２脚受部１２ｂに対応する部位は、第２脚受部１２ｂの支持壁部１３よりも上方の位置に存在するが、第１脚受部１２ａに対応する部位は、第１脚受部１２ａの支持壁部１３よりも下方に位置している。これにより、例えば、一対の第１脚受部１２ａの支持壁部１３に対して真っ直ぐな板状体を掛け渡したとしても、かかる板状体がワーク２１に圧接しないように構成されている。つまり、上記のように、本実施形態では、一対の第１支脚部１１ａの間において、第１支脚部１１ａと同じ長さだけ下方に突出する収納用凸部３１が形成されているが、図８に示すように、箱型容器１をスタッキングしても、上側の箱型容器１の収納用凸部３１と、下側の箱型容器１のワーク２１とが圧接しないように（第１支脚部１１ａが第１脚受部１２ａの支持壁部１３に確実に当接して支持されるように）なっている。 Further, as described above, although the height positions of the support wall portions 13 of the first leg receiving portion 12a and the second leg receiving portion 12b are aligned, in the present embodiment, the linear portion 22 is inclined. Since the workpiece 21 is accommodated in the box-shaped container 1 in this state, the relative positional relationship in the vertical direction between the support wall portion 13 of each leg receiving portion 12a, 12b and the workpiece 21 is changed. That is, as shown in FIG. 5, the portion corresponding to the second leg receiving portion 12 b of the linear portion 22 of the workpiece 21 exists at a position above the support wall portion 13 of the second leg receiving portion 12 b. The site | part corresponding to the 1st leg receiving part 12a is located below the support wall part 13 of the 1st leg receiving part 12a. Thereby, for example, even if a straight plate-like body is stretched over the support wall portion 13 of the pair of first leg receiving portions 12 a, the plate-like body is configured not to be pressed against the workpiece 21. That is, as described above, in the present embodiment, the storage convex portion 31 that protrudes downward by the same length as the first support leg portion 11a is formed between the pair of first support leg portions 11a. As shown in FIG. 8, even when the box-shaped container 1 is stacked, the storage convex portion 31 of the upper box-shaped container 1 and the work 21 of the lower box-shaped container 1 are not pressed against each other (the first support leg). The portion 11a is supported so as to be surely abutted against and supported by the support wall portion 13 of the first leg receiving portion 12a).

さらに、図１、図７等に示すように、直線支持部３５の各保持部３６、３７には、箱型容器１に収容された各ワーク２１の直線部２２の両側方において上方に突出し、箱型容器１の短手方向における直線部２２の位置ずれを防止するための横ずれ防止凸部３８が形成されている。本実施形態では、基端側保持部３６の横ずれ防止凸部３８のうち、箱型容器１の短手方向中央に設けられた横ずれ防止凸部３８ａの上面と、脚受部１２の支持壁部１３の上面とが同じ高さとなるように構成されている。 Furthermore, as shown in FIG. 1, FIG. 7, etc., each holding part 36, 37 of the linear support part 35 protrudes upward on both sides of the linear part 22 of each workpiece 21 accommodated in the box-shaped container 1, A lateral displacement prevention convex portion 38 is formed for preventing the displacement of the straight portion 22 in the lateral direction of the box-shaped container 1. In the present embodiment, among the lateral slip prevention convex portions 38 of the base end side holding portion 36, the upper surface of the lateral slip prevention convex portion 38 a provided at the center in the short direction of the box-shaped container 1 and the support wall portion of the leg receiving portion 12. It is comprised so that the upper surface of 13 may become the same height.

また、図５等に示すように、短辺側側壁部７には、支脚部１１や脚受部１２が形成されておらず、その内側面はほぼ平坦面となっている。このため、例えば、ワーク２１を短辺側側壁部７の内側面に沿わせてスライドさせて箱型容器１に収容することもできる。さらに、基端部２５と対向し、突部収容部３２の一側面を画定する第１短辺側側壁部７ａは、箱型容器１に収容されたワーク２１の突出部２３の先端部に対して近接又は当接するとともに、先端部２６と対向する第２短辺側側壁部７ｂは、先端部２６に対して近接又は当接状態となっている。そして、箱型容器１の長手方向が傾く等した場合、ワーク２１の突出部２３と突部収容部３２の内側面とが当接したり、直線部２２の端部と第２短辺側側壁部７ｂとが当接したりすることで、ワーク２１の長手方向における位置ずれが防止されるようになっている。 Further, as shown in FIG. 5 and the like, the short side wall portion 7 is not formed with the supporting leg portion 11 or the leg receiving portion 12, and the inner side surface thereof is substantially flat. For this reason, for example, the workpiece 21 can be slid along the inner side surface of the short side wall portion 7 and accommodated in the box-type container 1. Furthermore, the first short side wall portion 7 a that faces the base end portion 25 and defines one side surface of the protrusion accommodating portion 32 is opposed to the distal end portion of the protruding portion 23 of the work 21 accommodated in the box-shaped container 1. The second short side wall portion 7b facing the tip portion 26 and in close proximity or contact with the tip portion 26 is in the proximity or contact state with the tip portion 26. When the longitudinal direction of the box-shaped container 1 is inclined, the projecting portion 23 of the workpiece 21 and the inner surface of the projecting portion accommodating portion 32 come into contact with each other, or the end portion of the straight portion 22 and the second short side wall portion. 7b abuts, so that the displacement of the workpiece 21 in the longitudinal direction is prevented.

さらに、底壁構成部２のうち直線支持部３５を構成する部位、特に、先端側保持部３７を構成する部位は、収納用凸部３１や支脚部１１の下端部よりも上方に位置している。また、底壁構成部２のうち先端側保持部３７を構成する部位の下面側には、図２に示すように、相対する一対の第２支脚部１１ｂの丁度中間位置において下方に突出する補助脚部４１が下方に突設されている。当該補助脚部４１の下端部は、その他の支脚部１１の下端部と高さ位置が揃えられており（仮想の同一平面上にあり）いる。すなわち、箱型容器１の先端側保持部３７側（第２短辺側側壁部７ｂ側）の部位については、支脚部１１及び補助脚部４１によって支持される格好となり、設置面に設置した場合、底壁構成部２が橋桁のように設置面から離間した位置で支持されることとなる。 Furthermore, the part which comprises the linear support part 35 among the bottom wall structure parts 2, especially the part which comprises the front end side holding part 37 are located above the convex part 31 for storage, or the lower end part of the support leg part 11. FIG. Yes. Further, on the lower surface side of the portion constituting the distal end side holding portion 37 in the bottom wall constituting portion 2, as shown in FIG. 2, the auxiliary projecting downward just at the intermediate position between the pair of opposing second support legs 11b. The leg part 41 protrudes downward. The lower end portion of the auxiliary leg portion 41 is aligned in height with the lower end portion of the other support leg portion 11 (on the same virtual plane). That is, when the portion of the box-shaped container 1 on the front end holding portion 37 side (second short side wall portion 7b side) is supported by the support leg portion 11 and the auxiliary leg portion 41, it is installed on the installation surface. The bottom wall constituting part 2 is supported at a position separated from the installation surface like a bridge girder.

また、箱型容器１がスタッキングされた場合には、図８に示すように、上側の箱型容器１の支脚部１１が下側の箱型容器１の脚受部１２に支持されるとともに、図９に示すように、上側の箱型容器１の補助脚部４１が、下側の箱型容器１の基端側保持部３６の横ずれ防止凸部３８（箱型容器１の短手方向中央に設けられた横ずれ防止凸部３８ａ）の上面に当接して支持される。当該補助脚部４１により、底壁構成部２の先端側保持部３７側の強度を高め、撓み変形等の発生を抑制することができる。さらに、スタッキング時において補助脚部４１を支持する横ずれ防止凸部３８ａの裏面側には補強用のリブ３９（図９参照）が設けられおり、当該横ずれ防止凸部３８ａの耐久性の向上が図られている。尚、基端側保持部３６の横ずれ防止凸部３８のうち短手方向中央の横ずれ防止凸部３８ａ以外のものは、補助脚部４１を支持する等の必要がなく、ワーク２１の位置ずれを防止できればよいため、軽量化のために、短手方向中央の横ずれ防止凸部３８ａよりも高さが低く構成されている。 Further, when the box-shaped container 1 is stacked, as shown in FIG. 8, the support leg portion 11 of the upper box-shaped container 1 is supported by the leg receiving portion 12 of the lower box-shaped container 1, As shown in FIG. 9, the auxiliary leg portion 41 of the upper box-shaped container 1 is provided with a lateral displacement prevention convex portion 38 (the center in the short direction of the box-shaped container 1) of the proximal end holding portion 36 of the lower box-shaped container 1. Is supported in contact with the upper surface of the lateral displacement prevention projection 38a). The auxiliary leg portion 41 can increase the strength of the bottom wall constituting portion 2 on the distal end side holding portion 37 side and suppress the occurrence of bending deformation or the like. Further, a reinforcing rib 39 (see FIG. 9) is provided on the back side of the lateral slip prevention convex portion 38a that supports the auxiliary leg portion 41 during stacking, thereby improving the durability of the lateral slip prevention convex portion 38a. It has been. Of the lateral displacement prevention convex portions 38 of the base end side holding portion 36, those other than the lateral displacement prevention convex portion 38a at the center in the short direction do not need to support the auxiliary leg portion 41, and the work 21 is displaced. In order to reduce the weight, the height is configured to be lower than the lateral shift prevention convex portion 38a at the center in the short direction.

加えて、図１等に示すように、底壁構成部２のうち基端側保持部３６と先端側保持部３７との間の部位には、上下に貫通する貫通孔４２が形成されている。これにより、軽量化及び省資源化が図られる上、ネスティングされた箱型容器１のうち上側の箱型容器１を持ち上げた際に、かかる貫通孔４２から上下に重なる箱型容器１間の空間に外気を導入し易くなる。従って、ネスティングした箱型容器１を抜き取る作業を行う際に、上下に重なる箱型容器１間の空間が負圧状態になり、かかる抜き取り作業をスムースに行えないといった事態を防止することができる。 In addition, as shown in FIG. 1 and the like, a through-hole 42 penetrating vertically is formed in a portion of the bottom wall constituting portion 2 between the proximal end side holding portion 36 and the distal end side holding portion 37. . As a result, the weight and resources can be saved, and the space between the box-type containers 1 that are vertically stacked from the through-hole 42 when the upper box-type container 1 is lifted out of the nested box-type containers 1. It becomes easy to introduce the outside air into. Accordingly, when the nested box-shaped container 1 is extracted, the space between the box-shaped containers 1 that are vertically overlapped is in a negative pressure state, and it is possible to prevent such a situation that the extraction operation cannot be performed smoothly.

さらに、図１、図４等に示すように、長辺側側壁部６の長手方向中央部を含む部位には、若干周壁部３の外側に膨出する挿入凹部４３が形成されている。これにより、箱型容器１に収容されているワーク２１（特に両サイドに収容されているワーク２１）を取出す際に、挿入凹部４３に手を差し入れて直線部２２の下側に手を掛けることができる。さらに、ワーク２１を箱型容器１に収容したりする際に、ワーク２１が直線支持部３５に支持されるまでワーク２１の下側を支持しておくことができる。また、一対の長辺側側壁部６のうち一方の挿入凹部４３には、周壁部３の外周方向（長辺側側壁部６の厚み方向）に貫通する持ち手孔４４が形成されている。つまり、箱型容器１が空の状態では、ワーク２１を収容した状態と同様に張り出し部４の下面に手を掛けて持ち運ぶことは勿論のこと、持ち手孔４４に手を差し入れて、その上方部位を握って持ち運ぶこともできるようになっている。 Further, as shown in FIGS. 1, 4, etc., an insertion concave portion 43 that slightly bulges outside the peripheral wall portion 3 is formed in a portion including the central portion in the longitudinal direction of the long side wall portion 6. Thereby, when taking out the work 21 accommodated in the box-shaped container 1 (particularly, the work 21 accommodated on both sides), a hand is inserted into the insertion recess 43 and a hand is placed below the straight portion 22. Can do. Furthermore, when the work 21 is accommodated in the box-type container 1, the lower side of the work 21 can be supported until the work 21 is supported by the linear support portion 35. Further, a handle hole 44 penetrating in the outer peripheral direction of the peripheral wall portion 3 (in the thickness direction of the long side wall portion 6) is formed in one insertion concave portion 43 of the pair of long side wall portions 6. That is, when the box-shaped container 1 is empty, it is possible to carry it by placing the hand on the lower surface of the overhanging portion 4 in the same manner as in the state in which the work 21 is accommodated. It is also possible to carry by holding the part.

加えて、図２等に示すように、張り出し部４は、周壁部３の上縁部から外周方向に向けて水平に延出するとともに、先端が下方に屈曲形成されて断面略Ｌ字状をなしている。また、張り出し部４の下面側と周壁部３の外面上部とを連結する補強リブ４５が周壁部３の周方向において所定間隔で設けられている。尚、張り出し部４の外周縁は基本的に凹凸がなく全体として略長方形状（コーナー部が面取り加工されている）となっている。また、支脚部１１、脚受部１２、挿入凹部４３のいずれにしても、長辺側側壁部６の対応部位を周壁部の外周側に膨出させることで形成されているが、上面視で張り出し部４の外周縁よりも外周側にまでは突出しないように構成されている。 In addition, as shown in FIG. 2 and the like, the overhanging portion 4 extends horizontally from the upper edge portion of the peripheral wall portion 3 toward the outer peripheral direction, and the tip is bent downward to have a substantially L-shaped cross section. There is no. In addition, reinforcing ribs 45 that connect the lower surface side of the overhanging portion 4 and the outer surface upper portion of the peripheral wall portion 3 are provided at predetermined intervals in the circumferential direction of the peripheral wall portion 3. Note that the outer peripheral edge of the overhanging portion 4 basically has no irregularities and has a substantially rectangular shape as a whole (the corner portion is chamfered). Moreover, in any of the support leg part 11, the leg support part 12, and the insertion recessed part 43, it is formed by expanding the corresponding part of the long side wall part 6 to the outer peripheral side of the peripheral wall part. It is comprised so that it may not protrude to the outer peripheral side rather than the outer periphery of the overhang | projection part 4. FIG.

尚、４つの脚受部１２の支持壁部１３の高さ位置が揃っていることから、箱型容器１をスタッキングしても箱型容器１自体が傾くことはなく、いずれの箱型容器１においても張り出し部４の上面は設置面と平行に延びている。また、支脚部１１と支脚部１１を支持する脚受部１２とが長辺側側壁部６の長手方向中央部を中心として対称位置に設けられているため、スタッキング時において上下に積み重なる箱型容器１の外周縁が大きくずれることはなく、ほぼ一致する。 Since the height positions of the support wall portions 13 of the four leg receiving portions 12 are aligned, the box-shaped container 1 itself does not tilt even when the box-shaped container 1 is stacked, and any box-shaped container 1 The upper surface of the overhanging portion 4 also extends parallel to the installation surface. Further, since the support leg part 11 and the leg receiving part 12 that supports the support leg part 11 are provided at symmetrical positions around the longitudinal center part of the long side wall part 6, the box-type container that is stacked up and down during stacking. The outer peripheral edge of 1 does not greatly deviate and almost coincides.

さて、上記のように構成されてなる箱型容器１をスタッキングした場合、図８等に示すように、上側の箱型容器１の収納用凸部３１が、下側の箱型容器１に収容されたワーク２１の先端部２６の上方において下側の箱型容器１の内側に進入し、先端部２６に近接配置された状態とされる。より具体的には、上下方向において、上側の箱型容器１の収納用凸部３１の下端部は、下側の箱型容器１に収容されたワーク２１の基端部２５の上縁部よりも下方に位置している。尚、底壁構成部２のうち直線支持部３５を構成する部位の下面は、収納用凸部３１の下端部よりも上方に位置しているため、スタッキングされても、下側の箱型容器１に収容されたワーク２１（直線部２２の基端部２５）と、上側の箱型容器１の底壁構成部２とが上下に離間しており、圧接することはない。 Now, when the box-shaped container 1 configured as described above is stacked, the storage convex portion 31 of the upper box-shaped container 1 is accommodated in the lower box-shaped container 1 as shown in FIG. The workpiece 21 enters the inside of the lower box-shaped container 1 above the tip portion 26 of the workpiece 21 and is placed in proximity to the tip portion 26. More specifically, in the vertical direction, the lower end portion of the storage convex portion 31 of the upper box-shaped container 1 is more than the upper edge portion of the base end portion 25 of the work 21 accommodated in the lower box-shaped container 1. Is also located below. In addition, since the lower surface of the site | part which comprises the linear support part 35 among the bottom wall structure parts 2 is located above the lower end part of the convex part 31 for storage, even if it is stacked, a lower box-shaped container The workpiece 21 accommodated in 1 (the base end portion 25 of the straight portion 22) and the bottom wall constituting portion 2 of the upper box-shaped container 1 are separated from each other in the vertical direction, and are not pressed against each other.

以上詳述したように、本実施形態によれば、直線部２２と、直線部２２から直交する方向に突出する突出部２３とを具備するワーク２１は、突出部２３が下向きに突出するような姿勢で箱型容器１に収容される。このため、箱型容器１の外周長（外寸）を極力小さくすることができる。さらに、ワーク２１を収容した状態の複数の箱型容器１を段積みする（スタッキングする）ことができるように構成されているため、運搬効率や保管効率の向上を図ることができる。 As described in detail above, according to the present embodiment, the workpiece 21 including the linear portion 22 and the protruding portion 23 protruding in a direction orthogonal to the linear portion 22 is such that the protruding portion 23 protrudes downward. It is accommodated in the box-type container 1 in the posture. For this reason, the outer peripheral length (outside dimension) of the box-shaped container 1 can be made as small as possible. Furthermore, since it is comprised so that the several box-shaped container 1 of the state in which the workpiece | work 21 was accommodated can be stacked (stacked), the improvement of conveyance efficiency and storage efficiency can be aimed at.

また、箱型容器１には、突出部２３を収容可能とする突部収容部３２を形成するべく、底壁構成部２から下方に突出する収納用凸部３１が形成されている。さらに、箱型容器１に収容されたワーク２１の直線部２２は、突出部２３が設けられていない側の先端部２６に向けて下方傾斜している。このため、箱型容器１をスタッキングさせた場合に、直線部２２が傾斜していることによって先端部２６の位置が下げられた分だけ、その上方に確保することのできた収容空間に対して、上側の箱型容器１の収納用凸部３１を進入させることができる。従って、複数の箱型容器１を上下に極力詰めてスタッキングすることができ、スタッキング状態におけるコンパクト化を図ることができる。 Further, in the box-shaped container 1, a storage convex portion 31 protruding downward from the bottom wall constituting portion 2 is formed so as to form a protrusion accommodating portion 32 that can accommodate the protruding portion 23. Furthermore, the linear portion 22 of the workpiece 21 accommodated in the box-type container 1 is inclined downward toward the tip portion 26 on the side where the protruding portion 23 is not provided. For this reason, when the box-shaped container 1 is stacked, with respect to the accommodation space that can be secured above it by the amount by which the position of the distal end portion 26 is lowered due to the inclination of the linear portion 22, The convex part 31 for storage of the upper box-type container 1 can be made to approach. Therefore, a plurality of box-shaped containers 1 can be stacked as much as possible up and down, and the stacking state can be reduced.

また、複数の箱型容器１を交互に１８０度回転させて積み重ねることでスタッキングされるため、下側の箱型容器１に収容されたワーク２１と、上側の箱型容器１に収容されたワーク２１とが、互いに１８０度回転した向きで、上側の箱型容器１の底壁構成部２を介して、相対配置されることとなる。このため、スタッキングされた複数の箱型容器１からなる積物の荷重の偏りを抑制でき、積物の倒壊等のおそれを防止することができる。 In addition, since the plurality of box-shaped containers 1 are alternately stacked by rotating 180 degrees and stacked, the work 21 accommodated in the lower box-shaped container 1 and the work accommodated in the upper box-shaped container 1 are stacked. 21 are arranged relative to each other via the bottom wall constituting portion 2 of the upper box-type container 1 in directions rotated by 180 degrees with respect to each other. For this reason, the bias of the load of the product which consists of the several box-shaped container 1 stacked can be suppressed, and fears, such as collapse of a product, can be prevented.

さらに、支脚部１１及び脚受部１２は、一対の長辺側側壁部６にのみ設けられ、短辺側側壁部７には設けられないようになっている。このため、例えば、短辺側側壁部７にも支脚部１１及び脚受部１２を設ける場合に比べ、箱型容器１の外寸を小さく構成することができる。また、相対する長辺側側壁部６のうち、一方の長辺側側壁部６に形成された支脚部１１と他方の長辺側側壁部６に形成された支脚部１１とが互いに相対する位置に形成されている（各長辺側側壁部６において形成された支脚部１１の形成ピッチが同じ）。このため、スタッキング状態において、一方の長辺側側壁部６と他方の長辺側側壁部６とでスタッキング時等の支持バランスが比較的大きく異なってしまうといった事態を回避することができ、段積み状態の安定化を図ることができる。特に、長辺側側壁部６及び短辺側側壁部７のうち横幅（周壁部３の周方向における長さ）が長い方の長辺側側壁部６に支脚部１１が形成されているため、支脚部１１の形成ピッチを極力大きくすることができ、スタッキング状態の安定化を図ることができる。 Further, the supporting leg portion 11 and the leg receiving portion 12 are provided only on the pair of long side wall portions 6 and are not provided on the short side wall portion 7. For this reason, for example, the outer dimension of the box-shaped container 1 can be made smaller than the case where the supporting leg portion 11 and the leg receiving portion 12 are provided also on the short side wall portion 7. Further, among the opposed long side wall portions 6, positions where the support leg portions 11 formed on one long side wall portion 6 and the support leg portions 11 formed on the other long side wall portion 6 face each other. (The pitches of the support legs 11 formed in each long side wall 6 are the same). For this reason, in the stacking state, it is possible to avoid a situation in which the support balance at the time of stacking and the like is relatively different between the one long side wall 6 and the other long side wall 6. The state can be stabilized. In particular, since the support leg portion 11 is formed on the long side wall portion 6 having the longer lateral width (the length in the circumferential direction of the peripheral wall portion 3) of the long side wall portion 6 and the short side wall portion 7, The formation pitch of the support legs 11 can be increased as much as possible, and the stacking state can be stabilized.

加えて、支脚部１１及び脚受部１２が設けられていない短辺側側壁部７の内側面は略平坦面となっている。従って、複数のワーク２１の端部に対向する短辺側側壁部７の内側面には凹凸がほぼ皆無であることから、各ワーク２１がその長手方向において位置ずれしそうになった場合でも、かかる短辺側側壁部７の内側面によって各ワーク２１の端部を安定して支持することができ、位置ずれを防止することができる。また、ワーク２１を収容する際にワーク２１の端部が短辺側側壁部７に引っ掛かるといった事態を防止することができ、収容作業性を向上させることができる。さらに、直線部２２に沿って延びる長辺側側壁部６に関しては、それぞれ１つのワーク２１に隣接するだけなので、長辺側側壁部６においては、隣接する１つのワーク２１のガタツキを防止する構成を設けるだけで済む。このため、ワーク２１のガタツキを防止する構成及び支脚部１１を設けるスペースを十分に確保することができ、ワーク２１のガタツキを招くことなく、支脚部１１を設けることができる。 In addition, the inner side surface of the short side wall portion 7 where the support leg portion 11 and the leg receiving portion 12 are not provided is a substantially flat surface. Therefore, since there is almost no unevenness on the inner side surface of the short side wall 7 facing the ends of the plurality of workpieces 21, even if each workpiece 21 is likely to be displaced in the longitudinal direction, The end portion of each workpiece 21 can be stably supported by the inner side surface of the short side wall portion 7, and displacement can be prevented. Moreover, the situation where the edge part of the workpiece | work 21 is caught by the short side wall part 7 when accommodating the workpiece | work 21 can be prevented, and accommodation workability | operativity can be improved. Further, since the long side wall 6 extending along the straight portion 22 is only adjacent to one workpiece 21, the long side wall 6 is configured to prevent rattling of one adjacent workpiece 21. All you need to do is provide. For this reason, the structure which prevents the play of the workpiece | work 21 and the space which provides the support leg part 11 can be ensured enough, and the support leg part 11 can be provided, without causing the play of the work 21.

また、長辺側側壁部６の長手方向中央部を含む部位には、周壁部３の外周側に膨出し、長辺側側壁部６に隣接して設置されているワーク２１の側方からかかるワーク２１の下方に手を差し入れることを可能とする挿入凹部４３が形成されている。このように、挿入凹部４３が形成されることで、箱型容器１に収容されているワーク２１を取出す際に、挿入凹部４３に手を差し入れて直線部２２の下側に手を掛けることができる。また、ワーク２１を箱型容器１に収容する際に、ワーク２１が直線支持部３５に支持されるまでワーク２１の下側を手で支持しておくことができる。従って、ワーク２１を箱型容器１に収容したり、ワーク２１を箱型容器１から取外したりする際の作業性の向上を図ることができる。さらに、支脚部１１が形成された長辺側側壁部６に対して挿入凹部４３が形成されているため、支脚部１１が形成されていない短辺側側壁部７に対して別途周壁部３の外周側に膨出する挿入凹部４３を形成する場合に比べ、箱型容器１の外寸を極力小さくすることができ、箱型容器１の大型化を抑制することができる。 Moreover, it swells to the outer peripheral side of the surrounding wall part 3 in the site | part containing the longitudinal direction center part of the long side wall part 6, and it starts from the side of the workpiece | work 21 installed adjacent to the long side wall part 6. An insertion recess 43 that allows a hand to be inserted under the workpiece 21 is formed. Thus, when the insertion recess 43 is formed, when taking out the workpiece 21 accommodated in the box-type container 1, it is possible to insert a hand into the insertion recess 43 and put a hand under the straight portion 22. it can. Further, when the work 21 is accommodated in the box-type container 1, the lower side of the work 21 can be supported by hand until the work 21 is supported by the linear support portion 35. Therefore, it is possible to improve workability when the work 21 is accommodated in the box-type container 1 or when the work 21 is detached from the box-type container 1. Furthermore, since the insertion recess 43 is formed in the long side wall portion 6 in which the support leg portion 11 is formed, the peripheral wall portion 3 is separately provided in the short side wall portion 7 in which the support leg portion 11 is not formed. Compared with the case where the insertion concave portion 43 that bulges to the outer peripheral side is formed, the outer size of the box-shaped container 1 can be made as small as possible, and an increase in the size of the box-shaped container 1 can be suppressed.

尚、上記実施形態の記載内容に限定されず、例えば次のように実施してもよい。勿論、以下において例示しない他の応用例、変更例も当然可能である。 In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

Such a configuration may be adopted. Moreover, the protrusion part 23 and the linear part 22 do not need to be orthogonal, and should just extend in the direction which mutually cross | intersects. Furthermore, in addition to the protruding portion 23, a protruding portion that protrudes in a direction intersecting from the linear portion 22 may be provided. However, it is assumed that a protruding portion 23 that is a protruding portion that protrudes most laterally from the straight portion 22 is provided at one end of the straight portion 22 or in the vicinity thereof. In addition, the workpiece in which the straight portion 22 and the protruding portion 23 are connected so as to be bendable via the joint portion may be configured to be accommodated in the box-shaped container 1 in a bent state.

（ｂ）また、箱型容器１に収容可能なワーク２１の数についても特に限定されるものではなく、１つ〜３つのいずれかでもよいし、５つ以上でもよい。また、上記実施形態では、ワーク２１は、直線部２２が箱型容器１の長辺側側壁部６に沿って延在するように収容されるが、特に当該構成に限定されるものではない。例えば、収容されるワーク２１の数が増えたり、ワーク２１の横幅が比較的大きくなったり、ワーク２１の直線部２２が比較的短くなったりする等した場合において、複数のワーク２１の直線部２２の端部に対向する側壁部が、直線部２２の長手方向に沿って延びる側壁部よりも横幅が相対的に長くなるように構成してもよい。 (B) Moreover, it does not specifically limit about the number of the workpiece | work 21 which can be accommodated in the box-type container 1, Any of 1-3 may be sufficient and 5 or more may be sufficient. Moreover, in the said embodiment, although the workpiece | work 21 is accommodated so that the linear part 22 may extend along the long side wall part 6 of the box-type container 1, it is not limited to the said structure in particular. For example, when the number of workpieces 21 to be accommodated increases, the width of the workpieces 21 becomes relatively large, or the straight portions 22 of the workpieces 21 become relatively short, the straight portions 22 of the plurality of workpieces 21. The side wall portion opposed to the end portion of the straight line portion 22 may be configured to have a relatively longer lateral width than the side wall portion extending along the longitudinal direction of the linear portion 22.

（ｃ）上記実施形態では、箱型容器１を設置面に設置する場合に支脚部１１が接地することによって箱型容器１が支持されるように構成されているが、スタッキング時に脚受部１２に支持される支脚部１１とは別の個所が設置面に接地して箱型容器１が支持されるように構成してもよい。但し、支脚部１１を利用することで、構成の簡素化を図ることができる。 (C) In the above embodiment, when the box-shaped container 1 is installed on the installation surface, the box-shaped container 1 is supported by the support leg 11 being grounded. The box-shaped container 1 may be configured to be supported at a place different from the supporting leg portion 11 supported by the grounding to the installation surface. However, simplification of the configuration can be achieved by using the support legs 11.

さらに、上記実施形態では、一対の第１支脚部１１ａ間に収納用凸部３１が形成されているが、箱型容器１（直線部２２）の長手方向において支脚部１１及び収納用凸部３１の形成位置をずらしてもよく、例えば、一対の第１脚受部１２ａ間に収納用凸部３１が形成されるように構成してもよい。また、上記実施形態では、長辺側側壁部６に支脚部１１及び脚受部１２が設けられているが、短辺側側壁部７に支脚部１１及び脚受部１２が設けられることとしてもよい。 Furthermore, in the said embodiment, although the convex part 31 for storage is formed between a pair of 1st support leg parts 11a, the support leg part 11 and the convex part 31 for storage in the longitudinal direction of the box-type container 1 (straight part 22). For example, the storage convex portion 31 may be formed between the pair of first leg receiving portions 12a. Moreover, in the said embodiment, although the support leg part 11 and the leg support part 12 are provided in the long side wall part 6, the support leg part 11 and the leg support part 12 may be provided in the short side wall part 7. Good.

（ｄ）上記実施形態では、箱型容器１はポリプロピレンにより構成されているが、ポリエチレン、ＰＥＴ、ポリアミド等その他の樹脂材料により構成されることとしてもよい。さらに、スタッキングやネスティングの向きを把握し易くするために、例えば、箱型容器１の長手方向中央部を挟んで一方側と他方側とで異なる着色が施されてもよい。 (D) In the said embodiment, although the box-type container 1 is comprised by the polypropylene, it is good also as comprising by other resin materials, such as polyethylene, PET, and polyamide. Furthermore, in order to make it easier to grasp the direction of stacking or nesting, for example, one side and the other side may be colored differently across the central portion in the longitudinal direction of the box-type container 1.
