Embodiment for Carrying out the Invention

[0009] [Embodiment 1] A container according to an embodiment of the present invention will be described with reference to the drawings. In the drawings, a three-dimensional coordinate system of the XYZ system is also shown. The XY plane defines a horizontal plane, and the Z axis defines a vertical direction (the negative direction of the Z axis is the direction of gravity).

[0010] [Schematic Configuration of Container 1] As shown in FIG. 1, the container 1 of the present embodiment includes a container body 2 and a partition 3 that can be installed in the container body 2. The container body 2 is a box-shaped structure provided with an opening at the top. The container body 2 can be folded. Note that the present invention is not limited to a configuration in which the container body 2 is foldable. The partition 3 is a plate-shaped structure, and by installing it in the accommodation space of the container body 2, the accommodation space can be partitioned (divided) in the vertical direction (height direction). Each of the container body 2 and the partition 3 will be described in detail below.

[0011] The container body 2 includes a bottom wall component 20, opposing first side wall portions 21 and 22, and opposing second side wall portions 23 and 24. The first side wall portions 21 and 22 and the second side wall portions 23 and 24 constitute a part of the side wall of the box-shaped container body 2 shown in the center of FIG. 1. The container body 2 is substantially rectangular in plan view, specifically has a rectangular shape in plan view, and the first side wall portions 21 and 22 are located opposite each other with the bottom wall component 20 interposed therebetween and are configured on the side walls on the long side of the rectangular shape in plan view. The second side wall portions 23 and 24 are also located opposite each other with the bottom wall component 20 interposed therebetween and are configured on the side walls on the short side of the rectangular shape in plan view.

[0012] The first side wall portions 21, 22 and the second side wall portions 23, 24 are all hingedly connected to the bottom wall component 20. As a result, each of the side wall portions 21 to 24 can be rotated and folded so as to lie above the bottom wall portion of the bottom wall component 20. On the other hand, when the first side wall portions 21, 22 and the second side wall portions 23, 24 are raised from the folded state to the assembled state shown in FIG. 1, they are configured to be able to maintain the state in which adjacent side wall portions are connected to each other. For example, adjacent side wall portions can be maintained in the raised state by locking with a locking function (not shown). In the folded state, the second side wall portions 23, 24 are sandwiched between the bottom wall portion of the bottom wall component 20 and the first side wall portions 21, 22.

[0013] On the inner surfaces of one of the first side wall portions 21 and the other first side wall portion 22, a plurality of installation portions (lower installation portion 411, upper installation portion 44) are provided at intervals in the vertical direction (Z-axis direction) to support the partition 3 at a predetermined position. Specifically, they are the lower installation portion 411 and the upper installation portion 44 shown in FIG. 2. Here, on the inner surface of one of the first side wall portions 21, a recess 41 recessed outward (in the positive X-axis direction) is provided, and the lower surface of the recess 41 extending in the vertical direction forms the lower installation portion 411.

[0014] The upper installation portion 44 is at a position higher (on the positive Z-axis side) than the lower installation portion 411. Specifically, the upper installation portion 44 is provided at an intermediate position in the vertical direction of the recess 41. Note that the arrangement position of the upper installation portion 44 only needs to be provided between the upper surface and the lower surface (lower installation portion 411) of the recess 41 (intermediate position), and is not limited to the central position in the Z-axis (vertical) direction. The lower installation portion 411 and the upper installation portion 44 are provided at the same position in the Y-axis direction in the Z-axis direction. A plurality of upper installation portions 44 may be provided in the Z-axis direction.

[0015] In the example of the present embodiment, as shown in FIG. 2, the recess 41 extending in the vertical direction is provided at four different positions along the Y-axis direction in one of the first side wall portions 21. Note that it is not limited to four positions.

[0016] On the inner surfaces of each of one first side wall portion 21 and the other first side wall portion 22, there is further provided a second recess 51 having a second lower installation portion 511 (lower installation portion) at a height different from that of the lower installation portion 411 of the recess 41. The second lower installation portion 511 is provided at a position different from each of the installation portions 411 and 44 in the horizontal direction and at a height different from each of the installation portions 411 and 44.

[0017] The second recess 51 is provided on the inner surface of one first side wall portion 21 so as to be recessed outward (in the positive X-axis direction), and the lower surface of the second recess 51 forms the second lower installation portion 511. The other first side wall portion 22 is provided with the same. The first end portion 35 and the second end portion 36 of the partition 3 can be placed on the second lower installation portion 511. As shown in FIG. 2, the second recess 51 (second lower installation portion 511) is adjacent to each recess 41 and is provided at four different positions along the Y-axis direction. Note that it is not limited to the adjacent mode, nor is it limited to four positions.

[0018] Note that one or more upper installation portions may be provided in the second recess 51, and the upper installation portions may be at the same height as the upper installation portion 44 of the recess 41 or at different heights.

[0019] The lower installation portions 411 provided on each of one first side wall portion 21 and the other first side wall portion 22 have the same height. Also, the upper installation portions 44 provided on each of one first side wall portion 21 and the other first side wall portion 22 have the same height. Also, the second lower installation portions 511 provided on each of one first side wall portion 21 and the other first side wall portion 22 have the same height.

[0020] The positions where the lower installation portion 411 and the upper installation portion 44 are provided on one first side wall portion 21 side and the positions where they are provided on the other first side wall portion 22 side are not in a line-symmetrical position along the Y-axis direction, but are provided at positions shifted in the Y-axis direction. In one example, they have a point-symmetrical positional relationship centered on the center point when the container body 2 is viewed in plan.

[0021] Here, as shown in FIG. 1, the partition 3 has a rectangular shape that conforms to the shape of the accommodation space of the container body 2, and includes ends that can be placed on each of the above-described installation parts at a pair of end sides along the long side (Y-axis). Specifically, one end side 31 of the pair of end sides along the long side (Y-axis) includes a first end 35, and the first end 35 can be placed on the installation parts (lower installation part 411 and upper installation part 44) provided on one first side wall part 21 and the second lower installation part 511.

[0022] Further, the other end side 32 of the pair of end sides includes a second end 36, and the second end 36 can be placed on the installation parts (lower installation part 411 and upper installation part 44) provided on the other first side wall part 22 and the second lower installation part 511. In a state where the pair of end sides 31 and 32 are arranged along the Y-axis, the first end 35 and the second end 36 are respectively portions formed in a protruding shape protruding outward along the X-axis.

[0023] By placing the partition 3 having such a structure on any one of the above-described lower installation part 411, upper installation part 44, and second lower installation part 511, the accommodation space can be partitioned (divided) in the Z-axis direction. FIG. 3 shows an example of the installation of the partition 3. For the sake of convenience of explanation, FIG. 3 shows the partition 3 with the illustration of the other first side wall part 22 and the other second side wall part 24 shown in FIG. 1 omitted. As shown in FIG. 3, by placing the partition 3 (the first end 35 and the second end 36) only on the second lower installation part 511 of the second recess 51, the accommodation space can be partitioned into two parts: the space between the partition 3 and the bottom wall part of the bottom wall component 20 and the space above the partition 3.

[0024] Also, for example, the partition 3 can be turned over and the partition 3 (the first end 35 and the second end 36) can be placed on the lower installation part 411 of the recess 41, and another partition 3 can be turned over and the partition 3 (the first end 35 and the second end 36) can be placed on the upper installation part 44 of the recess 41. In this case, the accommodation space can be partitioned into three parts: the upper stage, the middle stage, and the lower stage.

[0025] [Configuration of partition 3] Next, the configuration of the partition 3 will be described with reference to FIGS. 1, 10, and 11. As shown in FIGS. 1, 10, and 11, the partition 3 includes a rectangular plate member 34, and first end parts 38A, 38B that cover and are attached to sandwich the edge of the plate member 34 from the outside, and second end parts 39A, 39B. The plate member 34 is made of a hollow-structured plate member having a hollow part. The hollow-structured plate member is composed of, for example, corrugated cardboard made of resin, a foamed sheet made of resin, a honeycomb board made of resin, or the like. The first end parts 38A, 38B and the second end parts 39A, 39B are made of resin, for example. Note that the plate member 34 is not limited to a hollow-structured plate member having a hollow part, and may not have a hollow part.

[0026] The first end part 38A is attached to one end side 31 which is the long side of the rectangular plate member 34 in plan view, and a first end 35 is provided. The first end part 38B is attached to the other end side 32 which is the long side of the rectangular plate member 34 in plan view, and a second end 36 is provided. The second end parts 39A and 39B are attached to a pair of short sides of the rectangular plate member 34 in plan view. The end parts 38A, 38B, 39A, 39B attached to each of the four sides of the plate member 34 are attached so as to sandwich the plate member 34.

[0027] [Schematic Configuration of Engagement Structure Part] Next, when the partition 3 is placed on any installation part (lower installation part 411, upper installation part 44, second lower installation part 511), the schematic configuration of the engagement structure part in which the installation part and the ends 35, 36 can be engaged will be described with reference to FIGS. 2, 4 to 9. As shown in FIGS. 2 and 4, each lower installation part 411, each upper installation part 44, and each second lower installation part 511 disposed on each of one first side wall part 21 and the other first side wall part 22 are provided with a protrusion 61 protruding upward.

[0028] As shown in FIGS. 2 and 4, each protrusion 61 provided on each installation part 44, 411, 511 has substantially the same shape and protrudes upward from substantially the same position of each installation part 44, 411, 511. Specifically, as shown in FIGS. 4, 7, and 8, each protrusion 61 is formed in a substantially quadrangular prism shape with a rectangular cross-section that is long in the Y-axis direction and short in the X-axis direction. The width of each protrusion 61 in the Y-axis direction is formed to be about 1 / 4 or less of the width of each installation part 44, 411, 511 in the Y-axis direction.

[0029] The thickness of each protrusion 61 in the X-axis direction is formed to be about 1 / 2 or less of the width of each installation part 44, 411, 511 in the X-axis direction. Further, the height of each protrusion 61 in the Z-axis direction is formed to be about 1 / 2 of the thickness of the first end portion 35 and the second end portion 36. Each protrusion 61 is disposed at substantially the center of the left side portion rather than the center position in the left-right direction when viewed from the front of each installation part 44, 411, 511, and at substantially the center of the front side portion rather than the center position in the depth direction of each installation part 44, 411, 511.

[0030] Next, the configurations of the first end portion 35 and the second end portion 36 will be described with reference to FIGS. 5 to 8. As shown in FIG. 5, the first end part 38A and the first end part 38B have the same configuration. That is, since the first end portion 35 and the second end portion 36 have the same configuration, the configuration of the first end portion 35 will be described with reference to FIGS. 5 to 8. Here, as shown in FIGS. 3 and 5, in a state where the first end portion 35 and the second end portion 36 are placed on each second lower installation part 511, the positive Z-axis direction of the partition 3 is also referred to as the "front side" of the partition 3 and each end portion 35, 36. Also, in this state, the negative Z-axis direction of the partition 3 is also referred to as the "back side" of the partition 3 and each end portion 35, 36.

[0031] As shown in FIGS. 5 and 6, the first end portion 35 has a table shape in plan view that is slightly smaller than each of the installation portions 411, 44, and 511, and protrudes outward (in the positive X-axis direction) with substantially the same thickness as the first end portion part 38A. Further, as shown in FIGS. 5 to 8, on the back side where the first end portion 35 is placed on the second lower installation portion 511, about half of the width in the Y-axis direction facing the protrusion 61 is recessed toward the front side (in the positive Z-axis direction), forming a receiving recess 63A. The receiving recess 63A is recessed toward the front side (in the positive Z-axis direction) to a depth of about half or more of the height of the first end portion 35 in the Z-axis direction and at a depth slightly lower than the upper end surface of the first end portion 35. Further, on the upper side (on the positive Z-axis direction side) of the receiving recess 63A, a shallow relief portion 65A is formed. Therefore, when the first end portion 35 and the second end portion 36 are placed on the second lower installation portion 511, the receiving recess 63A is configured to receive the protrusion 61.

[0032] Also, as shown in FIGS. 5 to 8, on the front side of the first end portion 35, about half of the width in the Y-axis direction adjacent to the receiving recess 63A is recessed toward the back side (in the negative Z-axis direction), forming a receiving recess 63B. The receiving recess 63B is recessed toward the back side (in the negative Z-axis direction) to a depth of about half or more of the height of the first end portion 35 in the Z-axis direction and at a depth slightly higher than the lower end surface of the first end portion 35. That is, the receiving recess 63A and the receiving recess 63B are provided adjacent to each other along the longitudinal direction (Y-axis direction) of the end portions parts 38A and 38B.

[0033] Further, a relief portion 65B having a shallower depth than the receiving recess 63A is formed below (on the negative Z-axis direction side) the receiving recess 63B. Therefore, as shown in FIG. 9, when the partition 3 is turned inside out (turned inside out about the X-axis direction or the Y-axis direction) with the back side facing up, the first end portion 35 and the second end portion 36 are placed on the lower installation portion 411 or the upper installation portion 44. In this case, the receiving recess 63B is configured to be able to receive the protrusion 61. Therefore, the first end portion 35 and the second end portion 36 have receiving recesses 63A and 63B capable of receiving the protrusions 61 protruding from the respective installation portions 44, 411, and 511 on the front side surface (one surface) placed on the lower installation portion 411 or the upper installation portion 44 and the back side surface (the other surface opposite to one surface) placed on the second lower installation portion 511.

[0034] As a result, when the front side of the partition 3 is facing up (positive Z-axis direction) and the first end portion 35 and the second end portion 36 are placed on the second lower installation portion 511, an engaging structure portion is formed in which the protrusion 61 of the second lower installation portion 511 engages with each receiving recess 63A. Further, when the back side of the partition 3 is facing up (positive Z-axis direction) and the first end portion 35 and the second end portion 36 are placed on the upper installation portion 44 or the lower installation portion 411, an engaging structure portion is formed in which the protrusion 61 of the upper installation portion 44 or the lower installation portion 411 engages with each receiving recess 63B. As a result, when the partition 3 is placed on each of the installation portions 44, 411, and 511, it is possible to prevent the partition 3 from falling into the container body 2 due to the contents placed on the partition 3.

[0035] Further, as shown in FIGS. 5 and 7, the relief portion 65A and the receiving recess 63B of the first end portion 35 and the second end portion 36 form a continuous recess. As a result, when the front side of the partition 3 is facing up and placed on the second lower installation portion 511, it is difficult for parts or dust of the contents to be caught between the relief portion 65A and the receiving recess 63B. As shown in FIGS. 6 and 7, the relief portion 65B and the receiving recess 63A of the first end portion 35 and the second end portion 36 form a continuous recess. As a result, when the back side of the partition 3 is facing up and placed on the upper installation portion 44 or the lower installation portion 411, it is difficult for parts or dust of the contents to be caught between the relief portion 65B and the receiving recess 63A.

[0036] [Configuration of each end part 38A, 38B, 39A, 39B] Next, the configurations of the first end parts 38A, 38B and the second end parts 39A, 39B will be described with reference to FIGS. 5, 6, 8, and 10 to 16. As shown in FIGS. 12 and 13, each of the end parts 38A, 38B, 39A, 39B is a U-shaped cross-section structure body, and a plate insertion part 301 that is open in the direction of attachment to the plate material 34 (hereinafter referred to as the "attachment direction") is provided.

[0037] Specifically, each of the end parts 38A, 38B, 39A, 39B is composed of a first wall part 331, a second wall part 332, and a connecting wall part 333. The first wall part 331 is provided so as to extend in a direction parallel to two opposite sides of the plate material 34. The second wall part 332 is provided so as to face the first wall part 331 in the Z-axis direction and extend in a direction parallel to two opposite sides of the plate material 34. That is, the first wall part 331 and the second wall part 332 are provided so as to extend in the Y-axis direction or the X-axis direction. The connecting wall part 333 is provided so as to connect the side edges on the side opposite to the attachment direction of the first wall part 331 and the second wall part 332.

[0038] As shown in FIGS. 10 to 12, each first end 35 of the first end part 38A projects in a substantially trapezoidal shape in plan view to the side opposite to the attachment direction over the entire height in the Z-axis direction of the connecting wall part 333. Further, each second end 36 of the first end part 38B projects in a substantially trapezoidal shape in plan view to the side opposite to the attachment direction over the entire height in the Z-axis direction of the connecting wall part 333.

[0039] [Configuration of the connecting rib 335] As shown in FIGS. 12 to 15, a plurality of connecting ribs 335 that connect the first wall portion 331, the second wall portion 332, and the connecting wall portion 333 are provided on the inner surface side of each of the end parts 38A, 38B, 39A, and 39B. FIGS. 12 to 15 show the first end part 38A and the second end part 39A, but similarly, a plurality of connecting ribs 335 that connect the first wall portion 331, the second wall portion 332, and the connecting wall portion 333 are also provided on the inner surface side of the first end part 38B and the second end part 39B.

[0040] The plurality of connecting ribs 335 provided on each of the end parts 38A, 38B, 39A, and 39B are provided along the mounting direction and are arranged at substantially equal intervals in a direction (longitudinal direction) orthogonal to the mounting direction. Further, each of the plurality of connecting ribs 335 is located closer to the connecting wall portion 333 than the edges on the mounting direction side of the first wall portion 331 and the second wall portion 332.

[0041] [Configuration of the locking protrusions 341 and 345] Also, as shown in FIGS. 12, 14, and 15, the first wall portion 331 and the second wall portion 332 of each of the first end parts 38A and 38B have a plurality of locking protrusions 341 that protrude on the inner surface side. The locking protrusions 341 are provided at positions facing the first wall portion 331 and the second wall portion 332, respectively. The locking protrusions 341 are formed with a width so as to extend in the Y-axis direction in a plan view. The locking protrusions 341 are provided between the connecting ribs 335.

[0042] As shown in FIG. 12, in each of the locking protrusions 341, the wall surface on the back side (X-axis direction side) protrudes perpendicularly from the inner surfaces of the first wall portion 331 and the second wall portion 332 by a predetermined height and then inclines so as to gradually approach the inner surfaces toward the mounting direction side (opening side). Also, as shown in FIGS. 12 and 14, between the back side end surfaces of the locking protrusions 341 formed on the inner surface of the first wall portion 331 and the connecting wall portion 333, through holes 342 having a rectangular shape in a plan view with a width slightly longer than the length of each of the locking protrusions 341 in the Y-axis direction are formed.

[0043] Further, as shown in FIGS. 13 to 15, the first wall portions 331 and the second wall portions 332 of each of the second end parts 39A and 39B have a plurality of locking protrusions 345 protruding toward the inner surface side. The locking protrusions 345 are provided at positions facing the first wall portion 331 and the second wall portion 332, respectively. The locking protrusions 345 are formed with a width so as to extend in the X-axis direction in a plan view. The locking protrusions 345 are provided between the connecting ribs 335.

[0044] For the locking protrusion 345, the wall surface on the back side (Y-axis direction side) is a curved surface that curves backward from the inner surfaces of the first wall portion 331 and the second wall portion 332, and protrudes vertically by a predetermined height. Then, the left and right end portions incline so as to gradually approach the respective inner surfaces toward the mounting direction side (opening side). Also, as shown in FIGS. 13 and 14, between the back side curved surface of the locking protrusion 345 formed on the inner surface of the first wall portion 331 and the connecting wall portion 333, a through hole 346 having a substantially rectangular shape in plan view with an edge on the mounting direction side curved with a width slightly longer than the length of each locking protrusion 345 in the X-axis direction is formed.

[0045] [Configuration of the stacked protrusions and the stacked receiving portions] Further, as shown in FIGS. 5, 8, 10, 12 to 14, and 19, each of the end parts 38A, 38B, 39A, and 39B is provided with a plurality of stacked protrusions 347 protruding upward (in the positive Z-axis direction) from the upper end surface of the first wall portion 331. As shown in FIGS. 5, 12 to 14, and 19, each of the stacked protrusions 347 is formed in a substantially rectangular shape in plan view that is long in the longitudinal direction of each of the end parts 38A, 38B, 39A, and 39B and has a slightly tapered hollow structure.

[0046] The stacked projection 347 is provided at a substantially central position between the center in the width direction orthogonal to the longitudinal direction of the first wall portion 331 and the edge on the side of the connecting wall portion 333. The lower end portion of the stacked projection 347 has a rectangular shape in plan view, and for example, has a short side with a length of about 1 / 4 of the length in the width direction of the first wall portion 331 and a long side with a length of about 1 / 2 of the length in the width direction of the first wall portion 331. Further, the height of the stacked projection 347 from the first wall portion 331 is formed, for example, to be about 1 / 2 of the height from the inner surface of the second wall portion 332 to the inner surface of the first wall portion 331.

[0047] Also, as shown in FIGS. 6, 11 to 15, 17, and 19, at positions of the respective end parts 38A, 38B, 39A, and 39B facing the respective stacked projections 347 of the second wall portion 332, stacked receiving portions 348 capable of receiving the stacked projections 347 are formed. As shown in FIGS. 6, 11, 12, and 19, the stacked receiving portion 348 has a substantially square through-hole 348A formed in the second wall portion 332 with the inner surface of the connecting wall portion 333 as one side and into which the stacked projection 347 can be inserted. Further, the stacked receiving portion 348 has side walls 348B in a rectangular groove shape in plan view protruding vertically from the three sides on the mounting direction side of the through-hole 348A to the inner surface of the first wall portion 331.

[0048] As shown in FIGS. 17 and 19, the through-hole 348A is formed in a substantially square shape with one side being slightly longer than the long side of the stacked projection 347 having a substantially rectangular shape in plan view, for example, about 1.5 mm to 4 mm longer. Therefore, as shown in FIG. 18, a plurality of partitions 3 are stacked. As a result, as shown in FIGS. 17 and 19, the stacked projections 347 formed on the respective end parts 38A, 38B, 39A, and 39B of the lower partition 3 enter into the stacked receiving portions 348 formed on the respective end parts 38A, 38B, 39A, and 39B of the upper partition 3.

[0049] Also, as shown in FIGS. 17 and 19, the gaps between both short sides of the stepped projection 347 having a substantially rectangular shape in plan view and the inner surface of the stepped receiving portion 348 are smaller than the gaps between the long sides of the stepped projection 347 and the inner surface of the stepped receiving portion 348. As a result, the stepped receiving portions 348 formed on the second wall portions 332 of the first end parts 38A and 38B can regulate the insertion direction of the partition 3 stacked on the lower side into the plate material 34 of each of the second end parts 39A and 39B, that is, the mounting direction, and the movement in the direction opposite to the mounting direction. Further, the stepped receiving portions 348 formed on the second wall portions 332 of the second end parts 39A and 39B can regulate the insertion direction of the partition 3 stacked on the lower side into the plate material 34 of each of the first end parts 38A and 38B, that is, the mounting direction, and the movement in the direction opposite to the mounting direction.

[0050] Thereby, when the partitions 3 with the end parts 38A, 38B, 39A, and 39B attached to the plate material 34 are stacked and stored and transported with the front side facing up (the positive Z-axis direction), the stepped projection 347 is received in the stepped receiving portion 348 of the upper partition 3, so that it is possible to prevent collapse due to shaking, vibration, etc. Here, the stepped projection 347 and the stepped receiving portion 348 function as an example of a position regulating portion.

[0051] [Configuration of each side portion of the plate material 34] Next, the configuration of each side of the plate material 34 will be described with reference to FIGS. 10, 11, 14 to 16. As shown in FIGS. 10, 11, 14 to 16, a plurality of locked portions 351 for locking the locking projections 341 of the first end parts 38A and 38B are provided on one end side 31 and the other end side 32 of the plate material 34. The locked portions 351 penetrate in a rectangular shape in plan view that is long along the side.

[0052] In addition, on each side where the second end parts 39A and 39B of the plate material 34 are mounted, a plurality of locked parts 352 are provided to which the locking protrusions 345 of the second end parts 39A and 39B are locked. The locked parts 352 are substantially rectangular in plan view and penetrate along the side, and the inner surface on the outer side of each side forms a curved surface that curves outward so that the inner wall surface on the back side of the locking protrusion 345 is locked. Thus, when the plate material 34 is a resin corrugated board or the like, even if the ribs of the plate material 34 (in the case of a paper corrugated board, parts called the core, flutes, etc.) are arranged in the X-axis direction, the ribs of the plate material 34 are located on the inner surface on the outer side of the locked part 352, and the locking strength of the locking protrusion 345 can be ensured.

[0053] In addition, on each side of the plate material 34, engaged parts 353 are provided which are cut out in a rectangular groove shape into which the side walls 348B of the stacking receiving parts 348 of the end parts 38A, 38B, 39A, and 39B can be inserted at positions facing the side walls 348B. Also, on each side of the plate material 34, engaged parts 355 are provided which are formed in a notch groove shape into which the connecting ribs 335 of the end parts 38A, 38B, 39A, and 39B can be inserted at positions facing the connecting ribs 335.

[0054] [Configuration of both ends of each end part] The configuration of both ends of each of the end parts 38A, 38B, 39A, and 39B will be described based on FIGS. 10 to 15 and FIG. 17. As shown in FIGS. 10 to 12, FIG. 14, and FIG. 15, at both ends in the longitudinal direction (Y-axis direction) orthogonal to the mounting direction of each of the first end parts 38A and 38B, end face connecting walls 334 that connect the first wall part 331, the second wall part 332, and the connecting wall part 333 are closed.

[0055] Also, as shown in FIGS. 10, 11, 13 to 15, each of the second end parts 39A, 39B is formed with an insertion part 336 that is substantially rectangular in plan view and flat plate-shaped and protrudes outward from both end parts in the longitudinal direction (X-axis direction) orthogonal to the mounting direction. The insertion part 336 has a width that is slightly shorter than the width in the mounting direction (Y-axis direction) of the first wall part 331 and the second wall part 332, for example, a width that is about 2 mm to 4 mm shorter, and protrudes outward from the inner surfaces of the first wall part 331, the second wall part 332, and the connecting wall part 333. Therefore, the thickness of the insertion part 336 is formed to be substantially equal to the distance between the inner surfaces of the first wall part 331 and the second wall part 332. The protruding length of the insertion part 336 protruding from the end of the first wall part 331 is formed to be substantially the same length as the width in the mounting direction (X-axis direction) of the inner surface of the first wall part 331 of each of the first end parts 38A, 39A.

[0056] Also, as shown in FIGS. 12, 14, 15, and 17, each of the first end parts 38A, 39A is provided with a connecting rib 337 on the inner surface side at a position inside in the longitudinal direction from the inner surface of the end surface connecting wall 334 at both end parts in the longitudinal direction to connect the first wall part 331, the second wall part 332, and the connecting wall part 333. The distance from the inner surface of the end surface connecting wall 334 to the connecting rib 337 is formed to be substantially the same length as the width of the insertion part 336. Thereby, as shown in FIGS. 12 and 17, each of the first end parts 38A, 39A is surrounded by the inner surfaces of the end surface connecting wall 334, the first wall part 331, the second wall part 332, the connecting wall part 333, and the connecting rib 337 at both end parts in the longitudinal direction, and a receiving part 338 into which the insertion part 336 of each of the second end parts 39A, 39B is inserted is formed.

[0057] Also, as shown in FIGS. 12, 14, 15, and 17, each of the first end parts 38A, 38B has a locking protrusion 357 that protrudes from the inner surface sides of the first wall part 331 and the second wall part 332 of the receiving part 338 provided at both end parts in the longitudinal direction. Each locking protrusion 357 is provided at a position facing the first wall part 331 and the second wall part 332, respectively. Each locking protrusion 357 is provided at a substantially central position in the longitudinal direction (Y-axis direction) between the end surface connecting wall 334 and the connecting rib 337, and at a substantially central position in the width direction (X-axis direction) of the first wall part 331 and the second wall part 332.

[0058] The locking protrusion 357 is formed in a substantially rectangular shape in plan view having a length of about 1 / 4 to 1 / 3 of the longitudinal direction (Y-axis direction) distance between the end face connecting wall 334 and the connecting rib 337 in the Y-axis direction width. For each locking protrusion 357, the wall surface on the back side (X-axis direction side) protrudes perpendicularly from the inner surfaces of the first wall portion 331 and the second wall portion 332 by a predetermined height, and then inclines so as to gradually approach the respective inner surfaces toward the mounting direction side (opening side). Further, as shown in FIGS. 12 and 14, between the back side end face of the locking protrusion 357 formed on the inner surface of the first wall portion 331 and the connecting wall portion 333, a through hole 358 having a rectangular shape in plan view with a width slightly longer than the length of each locking protrusion 357 in the Y-axis direction is formed.

[0059] On the other hand, as shown in FIGS. 10, 11, 14 to 17, locking portions 359 for locking the respective locking protrusions 357 of the first end parts 38A and 38B are provided at both ends in the longitudinal direction (X-axis direction) of the insertion parts 336 provided at both ends of each of the second end parts 39A and 39B. The locked portion 359 penetrates in a long rectangular shape in plan view along the width direction (Y-axis direction) of each insertion portion 336.

[0060] [Assembly of each end part 38A, 38B, 39A, 39B to the plate material 34] Next, the assembly of each end part 38A, 38B, 39A, 39B to the plate material 34 will be described with reference to FIGS. 16 and 17. First, the operator arranges the edge on the short side (Y-axis direction side) of the plate material 34 along the first wall portion 331 of each of the second end parts 39A and 39B. In the state arranged in this way, the connecting rib 335 and the engaged portion 355, and the side wall 348B of the stacked receiving portion 348 and the engaged portion 353 are in positions facing each other.

[0061] Then, as shown in FIG. 16, the operator pushes each of the second end parts 39A and 39B toward the plate material 34 side (Y-axis direction side) while keeping each of the second end parts 39A and 39B facing the edge of the plate material 34. At this time, each locking protrusion 345 of each of the second end parts 39A and 39B can be pushed toward each locked portion 352 while sandwiching the edge of the plate material 34.

[0062] As a result, as shown in FIG. 17, the edges on the short side of the plate member 34 are fitted inside the first wall portion 331 and the second wall portion 332 of each of the second end parts 39A and 39B. Further, each connecting rib 335 of each of the second end parts 39A and 39B and the side walls 348B of each step stacking receiving portion 348 are inserted into the respective engaged portions 353 and 355 that face each other. Then, the locking protrusions 345 of each of the second end parts 39A and 39B are engaged with and locked to the respective locked portions 352 of the plate member 34. As a result, each of the second end parts 39A and 39B is connected to the edge on the short side (Y-axis direction side) of the plate member 34, and each of the second end parts 39A and 39B is assembled to the edge on the short side (Y-axis direction side) of the plate member 34.

[0063] Next, the operator arranges the edges on the long side (X-axis direction side) of the plate member 34 along the first wall portion 331 of each of the first end parts 38A and 38B. In the state arranged in this way, the connecting rib 335 and the engaged portion 355, and the side wall 348B of the step stacking receiving portion 348 and the engaged portion 353 are in positions facing each other. Further, the inserted portions 338 provided at both ends in the longitudinal direction (Y-axis direction) of each of the first end parts 38A and 38B and the insertion portions 336 provided at both ends in the longitudinal direction (X-axis direction) of each of the second end parts 39A and 39B are in positions facing each other.

[0064] Then, as shown in FIG. 16, the operator pushes each of the first end parts 38A and 38B toward the plate member 34 side (X-axis direction side) while keeping each of the first end parts 38A and 38B facing the edge of the plate member 34. At this time, each locking protrusion 341 of each of the first end parts 38A and 38B can be pushed toward each locked portion 351 of the edge of the plate member 34 while sandwiching the edge of the plate member 34. Further, each locking protrusion 357 provided at both ends in the longitudinal direction (Y-axis direction) of each of the first end parts 38A and 38B can be pushed toward the locked portion 359 of the insertion portion 336 while sandwiching the insertion portion 336 provided at both ends in the longitudinal direction (X-axis direction) of each of the second end parts 39A and 39B.

[0065] As a result, as shown in FIG. 17, the edge on the long side of the plate member 34 fits inside the first wall portion 331 and the second wall portion 332 of each of the first end parts 38A and 38B. Further, each connecting rib 335 of each of the first end parts 38A and 38B and the side wall 348B of each step receiving portion 348 are inserted into the engaged portions 353 and 355 facing each other. Then, each locking projection 341 of each of the first end parts 38A and 38B engages with and is locked to each locking portion 351 of the plate member 34. Further, each locking projection 357 provided at both ends in the longitudinal direction (Y-axis direction) of each of the first end parts 38A and 38B engages with and is locked to the locked portion 359 of the insertion portion 336 provided at both ends in the longitudinal direction (X-axis direction) of each of the second end parts 39A and 39B.

[0066] As a result, each of the first end parts 38A and 38B is connected to the edge on the long side (X-axis direction side) of the plate member 34, and each of the first end parts 38A and 38B is assembled to the edge on the long side (X-axis direction side) of the plate member 34. Further, both ends in the longitudinal direction (Y-axis direction) of each of the first end parts 38A and 38B and both ends in the longitudinal direction (X-axis direction) of each of the second end parts 39A and 39B are connected, and a frame-like assembly is formed on the peripheral edge of the plate member 34. The plate member 34 can be reinforced by the end parts 38A, 38B, 39A, and 39B.

[0067] Further, the insertion portion 336 provided at both ends in the longitudinal direction (X-axis direction) of each of the second end parts 39A and 39B is inserted into and locked to the insertion-receiving portion 338 provided at both ends in the longitudinal direction (Y-axis direction) of each of the first end parts 38A and 38B. Further, the insertion portion 336 enters between the end-face connecting wall 334 and the connecting rib 337 that constitute the insertion-receiving portion 338. As a result, displacement of each insertion portion 336 in a direction (Y-axis direction) orthogonal to the insertion direction into the insertion-receiving portion 338 is restricted. Thus, it is possible to make it difficult for each of the second end parts 39A and 39B to come off from the edge of the plate member 34. Here, the insertion portion 336 and the insertion-receiving portion 338 function as an example of a position restricting portion.

[0068] [Modification Example 1] For example, the protrusion 61 may be disposed at a substantially central position on the right side of the central position in the left - right direction in the front view of the lower installation portion 411 and the upper installation portion 44 of each recess 41, and the second lower installation portion 511 of each second recess 51, and also at a substantially central position on the front - side portion of the central position in the depth direction of each installation portion 44, 411, 511. Further, when the front side of the partition 3 is upward (positive Z - axis direction), the receiving recess 63B may be disposed on the left side in the plan view of the first end portion 35 and the second end portion 36, and the receiving recess 63A may be disposed on the right side in the plan view.

[0069] Thereby, when the front side of the partition 3 is upward (positive Z - axis direction) and the first end portion 35 and the second end portion 36 are placed on the second lower installation portion 511, an engaging structure portion is formed in which the protrusion 61 of the second lower installation portion 511 engages with each receiving recess 63A. Also, when the back side of the partition 3 is upward (positive Z - axis direction) and the first end portion 35 and the second end portion 36 are placed on the upper installation portion 44 or the lower installation portion 411, an engaging structure portion is formed in which the protrusion 61 of the upper installation portion 44 or the lower installation portion 411 engages with each receiving recess 63B. As a result, when the partition 3 is placed on each installation portion 44, 411, 511, it is possible to prevent the partition 3 from falling into the container body 2 due to the contents placed on the partition 3.

[0070] [Modification Example 2] For example, when the relief portions 65A of each first end portion 35 and each second end portion 36 are eliminated and the front side of the partition 3 is upward (positive Z - axis direction), the bottom of the receiving recess 63A may be formed to form the upper ends of each first end portion 35 and each second end portion 36. Also, when the relief portions 65B of each first end portion 35 and each second end portion 36 are eliminated and the front side of the partition 3 is upward (positive Z - axis direction), the bottom of the receiving recess 63B may be formed to form the lower ends of each first end portion 35 and each second end portion 36.

[0071] As a result, it becomes possible to increase the depth of each receiving recess 63A and 63B, and increase the height of the protrusion 61 provided on the lower installation portion 411 and the upper installation portion 44 of each recess 41, and the second lower installation portion 511 of each second recess 51. As a result, it is possible to improve the engagement strength between the protrusion 61 provided on each installation portion 44, 411, 511 and each receiving recess 63A, 63B.

[0072] [Modification Example 3] For example, instead of the protrusion 61 on the lower installation portion 411 and the upper installation portion 44 of each recess 41, and the second lower installation portion 511 of each second recess 51, a recess 71 that depresses downward (in the negative Z-axis direction) with a predetermined depth, for example, a depth of about 5 mm to 10 mm, may be provided. And instead of the receiving recess 63A at each first end 35 and each second end 36, a protrusion 72A that protrudes downward (in the negative Z-axis direction) from the lower surface of each first end 35 and each second end 36 and can be inserted into the recess 71 may be provided. Further, instead of the receiving recess 63B at each first end 35 and each second end 36, a protrusion 72B that protrudes upward (in the positive Z-axis direction) from the upper surface of each first end 35 and each second end 36 and can be inserted into the recess 71 may be provided.

[0073] As a result, when the front side of the partition 3 is upward (in the positive Z-axis direction) and the first end 35 and the second end 36 are placed on the second lower installation portion 511, an engagement structure portion in which the protrusion 72A engages with the recess 71 of the second lower installation portion 511 is formed. Also, when the back side of the partition 3 is upward (in the positive Z-axis direction) and the first end 35 and the second end 36 are placed on the upper installation portion 44 or the lower installation portion 411, an engagement structure portion in which the protrusion 72B engages with the recess 71 of the upper installation portion 44 or the lower installation portion 411 is formed. As a result, when the partition 3 is placed on each installation portion 44, 411, 511, it is possible to prevent the partition 3 from falling into the container body 2 due to the contents placed on the partition 3.

[0074] [Modification Example 4] For example, the lengths of the first end parts 38A and 38B in the longitudinal direction (Y-axis direction) can be shortened and assembled to the edge on the short side (Y-axis direction side) of the plate material 34. In this case, on the edge on the short side (Y-axis direction side) of the plate material 34, a locked part 351 may be formed at a position facing each locking protrusion 341 instead of the locked part 352. Also, the lengths of the second end parts 39A and 39B in the longitudinal direction (X-axis direction) can be lengthened and assembled to the edge on the long side (X-axis direction side) of the plate material 34. In this case, on the edge on the long side (X-axis direction side) of the plate material 34, a locked part 352 may be formed at a position facing each locking protrusion 345 instead of the locked part 351.

[0075] In this case, after the operator assembles the second end parts 39A and 39B to the edge on the long side (X-axis direction side) of the plate material 34, the operator may assemble the first end parts 38A and 38B to the edge on the short side (Y-axis direction side) of the plate material 34. As a result, both ends in the longitudinal direction (X-axis direction) of the first end parts 38A and 38B and both ends in the longitudinal direction (Y-axis direction) of the second end parts 39A and 39B are connected and assembled in a frame shape to the peripheral edge of the plate material 34.

[0076] Thereby, the plate material 34 can be reinforced by the end parts 38A, 38B, 39A, and 39B. Also, displacement of each insertion part 336 in a direction (X-axis direction) orthogonal to the insertion direction into the inserted part 338 is restricted. As a result, it is possible to make it difficult for the second end parts 39A and 39B to come off from the edge of the plate material 34.

[0077] [Modification Example 5] For example, instead of the through holes 348A of the stacked portion receiving portions 348 formed in the second wall portions 332 of the second end portions 39A and 39B, stacked projections 347 may be provided. Further, instead of the stacked projections 347 formed in the first wall portions 331 of the second end portions 39A and 39B, through holes 348A of the stacked portion receiving portions 348 may be formed. Thereby, when the partitions 3 with the end portions 38A, 38B, 39A, and 39B attached to the plate material 34 are stacked for storage and transportation with the back side (in the positive Z-axis direction) facing up, the stacked projections 347 are received in the stacked portion receiving portions 348 of the upper partition 3, so that collapse due to shaking, vibration, etc. can be prevented.

[0078] [Modification Example 6] When a plurality of partitions 3 are stacked, the gaps between both short side portions of the stacked projection 347 having a substantially rectangular shape in plan view and the inner surface of the stacked portion receiving portion 348 may be such that the gap between the stacked projection 347 and the stacked portion receiving portion 348 that faces the approximate center of each side of the plate material 34 is the smallest among the plurality of stacked projections 347 and stacked portion receiving portions 348. Further, the gaps between both short side portions of the stacked projection 347 having a substantially rectangular shape in plan view and the inner surface of the stacked portion receiving portion 348 may be gradually reduced as they go from both end portions of each side of the plate material 34 toward the position facing the approximate center. Thereby, it becomes easier to stack a plurality of partitions 3, and workability can be improved.

[0079] [Modification Example 7] For example, the protrusion 61 may be disposed at the center position in the left-right direction in front view of the lower installation portion 411 and the upper installation portion 44 of each recess 41, and the second lower installation portion 511 of each second recess 51. Further, each receiving recess 63A, 63B may be provided on the front and back of the approximate center position (center position in the Y-axis direction) in plan view of the first end 35 and the second end 36, respectively.

[0080] Thus, when the front side of the partition 3 is facing up (the positive Z-axis direction) and the first end portion 35 and the second end portion 36 are placed on the second lower installation portion 511, an engaging structure portion is formed in which the protrusion 61 of the second lower installation portion 511 engages with each receiving recess 63A. Further, when the back side of the partition 3 is facing up (the positive Z-axis direction) and the first end portion 35 and the second end portion 36 are placed on the upper installation portion 44 or the lower installation portion 411, an engaging structure portion is formed in which the protrusion 61 of the upper installation portion 44 or the lower installation portion 411 engages with each receiving recess 63B.

[0081] [Modification Example 8] It is not necessary to attach the end parts 38A, 38B, 39A, and 39B to all the side edges of the plate material 34 of the partition 3. For example, it is not necessary to attach one or both of the second end parts 39A and 39B to the side edge on the short side (Y-axis direction side) of the plate material 34. Then, the first end parts 38A and 38B may be attached to the side edges on the long side (X-axis direction side) of the plate material 34. Thereby, the strength of the partition 3 can be improved by the first end parts 38A and 38B.
