[0009] The present disclosure relates to a container, and more particularly to a container provided with a partition member that divides an inner region of a container body.

[0010] (1) Implementation form A container 1 of this embodiment includes a container body 2 and a partition member 3 that can be installed in the container body 2, as shown in FIG.

[0011] (Container body) The container body 2 constitutes the main body of the container 1. As shown in Fig. 2, the container body 2 has a bottom 20 and a plurality of side walls 21, 22. Specifically, the container body 2 has a pair of opposing side walls 21 and another pair of opposing side walls 22 as the plurality of side walls 21, 22. Hereinafter, each of the pair of side walls 21 will be referred to as a first side wall 21, and each of the other pair of side walls 22 will be referred to as a second side wall 22, as necessary.

[0012] The container body 2 of this embodiment is a folding container for transportation that can be transformed into an assembled state and a folded state. When the container body 2 is in the assembled state shown in Fig. 2, the side walls 21, 22 stand upright relative to the bottom 20. In this case, the container body 2 is box-shaped with an upward opening, and an inner area 23 surrounded by a pair of first side walls 21 and a pair of second side walls 22 is formed inside the container body 2. This inner area 23 is used as a storage space for storing articles. When the container body 2 is in the folded state, the side walls 21, 22 are folded down and overlap the bottom 20, and the container body 2 is roughly plate-shaped.

[0013] In this disclosure, unless otherwise specified, the container 1 will be described when the container body 2 is in an assembled state as shown in Fig. 1. In addition, in this disclosure, for convenience, directions are defined as shown in Fig. 1. That is, with the center position of the container 1 as a reference, the direction toward the bottom 20 is defined as the downward direction and the opposite direction is defined as the upward direction, and one direction parallel to the length direction of the rectangular bottom 20 is defined as the forward direction and the opposite direction is defined as the rearward direction. In addition, the left and right directions are defined based on a view looking rearward from the front.

[0014] The bottom 20 and the side walls 21, 22 of the container body 2 shown in Fig. 2 are made of synthetic resin, for example, polypropylene. Note that the bottom 20 and the side walls 21, 22 may be made of a synthetic resin other than polypropylene, or may be made of a material other than synthetic resin.

[0015] The bottom 20 is formed in a rectangular shape when viewed from above. The multiple side walls 21, 22 are rotatably connected to the bottom 20. Specifically, the pair of first side walls 21 are rotatably attached to a pair of opposing sides of the rectangular bottom 20, and the pair of second side walls 22 are rotatably attached to another pair of opposing sides of the rectangular bottom 20.

[0016] The container body 2 is not limited to a foldable container. The container body 2 may be, for example, a container in which the side walls 21, 22 are attached to the bottom 20 so as not to rotate. The container body 2 may also be an integrally molded product in which the side walls 21, 22 are integrally formed with the bottom 20.

[0017] The bottom 20 of this embodiment is formed in a rectangular shape extending in one direction when viewed from above, and has a pair of opposing long sides and a pair of opposing short sides. The bottom 20 has a plurality of raised portions 201, 202 protruding upward from the peripheral portion of the rectangular bottom 20.

[0018] The bottom portion 20 has a total of four rising portions, including a pair of first rising portions 201 and a pair of second rising portions 202. The pair of first rising portions 201 are formed on a pair of long sides of the rectangular bottom portion 20. The pair of second rising portions 202 are formed on a pair of opposing short sides of the rectangular bottom portion 20. Each of the rising portions 201, 202 protrudes upward from the bottom portion 20.

[0019] The lower ends of the pair of first side walls 21 are connected to the pair of first rising parts 201 so as to be rotatable about a rotation axis parallel to the front-rear direction. The lower ends of the pair of second side walls 22 are connected to the pair of second rising parts 202 so as to be rotatable about a rotation axis parallel to the left-right direction. That is, the pair of first side walls 21 are rotatably attached to a pair of long sides of the bottom 20, and the pair of second side walls 22 are rotatably attached to a pair of short sides of the bottom 20. Each of the first side walls 21 may be rotatably attached to the short sides of the bottom 20, and each of the second side walls 22 may be rotatably attached to the long sides of the bottom 20. The bottom 20 may be formed in a square shape when viewed from above.

[0020] The container body 2 can be transformed into an assembled state (see FIG. 2) and a folded state by rotating each side wall 21, 22 relative to the bottom 20. The container 1 in the assembled state can be transformed into a folded state by rotating each second side wall 22 relative to the bottom 20 to tilt it onto the bottom 20, and then rotating each first side wall 21 relative to the bottom 20 to tilt the pair of first side walls 21 onto the pair of second side walls 22.

[0021] The container 1 in the folded state can be transformed into the assembled state by rotating each first side wall 21 relative to the bottom 20 to make it stand up, and then rotating each second side wall 22 relative to the bottom 20 to make it stand up.

[0022] When the container body 2 is in an assembled state, the upper ends of the first side walls 21 and the second side walls 22 are located at the same height. The length in the front-to-rear direction of each first side wall 21 is longer than the combined length of the vertical length of one second side wall 22 and the vertical length of the other second side wall 22. Therefore, in the folded container body 2, the pair of second side walls 22 do not overlap each other vertically, and the intermediate portions of each first side wall 21 in the front-to-rear direction do not overlap the pair of second side walls 22 when viewed from above.

[0023] 2, 3A, 3B, and 7, each second side wall 22 has a pair of notches 220. The pair of notches 220 are formed at both ends in the left-right direction of the second side wall 22. Each notch 220 penetrates the second side wall 22 in the front-rear direction.

[0024] As shown in Fig. 2, Fig. 3A and Fig. 8, each first side wall 21 has a pair of fitting portions 210. The pair of fitting portions 210 is formed on both ends of the first side wall 21 in the front-rear direction. Each fitting portion 210 is a protrusion formed on the inner surface of the first side wall 21, and protrudes from the first side wall 21 toward the corresponding second side wall 22 side (inner side in the left-right direction). When the container body 2 is in an assembled state as shown in Fig. 2, the pair of fitting portions 210 of each first side wall 21 fits into the corresponding notch portion 220 of the second side wall 22, and closes the notch portion 220.

[0025] (locking member) The container 1 further includes a pair of locking members 4 provided on the pair of second side walls 22, respectively. Each locking member 4 is attached to the outer surface of the corresponding second side wall 22 so as to be movable in the up and down direction. Each locking member 4 is made of, for example, a synthetic resin. Note that the material of each locking member 4 is not limited.

[0026] An upward force is applied to the locking member 4 by, for example, an elastic member such as a spring or rubber provided separately from the locking member 4 on the second side wall 22, or an elastic portion such as a leaf spring that is part of the locking member 4.

[0027] 2, the locking members 4 provided on the second side walls 22 are caught on the first side walls 21 standing relative to the bottom 20. As a result, the second side walls 22 standing relative to the bottom 20 are locked in a locked state in which they are restricted from rotating relative to the bottom 20.

[0028] To release the locked state, the user only has to move the locking member 4 downward relative to the second side wall 22. This disengages the locking member 4 of the second side wall 22 from the corresponding first side wall 21, and each second side wall 22 enters an unlocked state in which rotation relative to the bottom portion 20 is not restricted.

[0029] The locking member 4 can be omitted. In this case, for example, by forming an engagement portion on each second side wall 22 that detachably engages with each first side wall 21, the shape of the container 1 in the assembled state can be maintained.

[0030] (Partition material) 3A, the container 1 further includes at least one partition member 3. The container 1 of this embodiment includes a plurality of partition members 3. It is to be noted that the container 1 may include only one partition member 3.

[0031] Any number of partition members 3 may be installed in the container body 2 depending on the application, etc. The container 1 may also be used in a state where no partition members 3 are installed in the container body 2.

[0032] Each partition member 3 is installed in the container body 2, for example, as shown in Fig. 3A, and divides the inner region 23 of the container body 2 into upper and lower regions. Each partition member 3 is supported by a pair of first side walls 21, and is thus removably installed in the container body 2. Each partition member 3 supports articles stored in the inner region 23 of the container body 2 from below. In this disclosure, unless otherwise specified, the partition member 3 will be described in a state in which it is installed in the container body 2.

[0033] In the present embodiment, three partition members 3 can be installed in the container body 2. In the example shown in Fig. 3A, two partition members 3 are installed at an interval in the vertical direction in the container body 2. In this case, the inner area 23 of the container body 2 is partitioned by the two partition members 3 into three storage areas aligned in the vertical direction.

[0034] 6A, only one partition member 3 is installed in the container body 2. In this case, the inner area 23 of the container body 2 is divided into two storage areas arranged vertically by one partition member 3. The number of partition members 3 that can be installed in the container body 2 is not limited. For example, the number of partition members 3 that can be installed in the container body 2 may be four or more, or only one or only two.

[0035] Each partition member 3 has the same shape and size. Each partition member 3 is formed in a flat plate shape with the thickness direction parallel to the up-down direction. Each partition member 3 is formed in a shape that is difficult to deform as a whole, and when installed in the container body 2, the relative positions of both ends in the left-right direction placed on the mounting part 250 of the container body 2 described below are difficult to change. In other words, each partition member 3 is not one in which both side portions are rotatably connected via hinges like the inner lid shown in Patent Document 1, and does not have a hinge for deforming the partition member 3.

[0036] 1, each partition member 3 has a shape that generally matches the inner region 23 of the container body 2 when viewed from above. That is, each partition member 3 is formed in a generally rectangular shape extending in the front-rear direction when viewed from above.

[0037] Specifically, each partition member 3 is formed in a rectangular shape with each of the four corners cut out when viewed from above. When the partition member 3 is formed in this manner, the cut out corners of the partition member 3 can be used as handles when the partition member 3 is placed on the container body 2. The left-right length of each partition member 3 is approximately equal to the distance between a pair of first side walls 21, and the front-rear length of each partition member 3 is approximately equal to the distance between a pair of second side walls 22.

[0038] Each partition member 3 has rigidity and is difficult to deform, but may be a member that is easily deformed. The shape and size of each partition member 3 are not limited. For example, each partition member 3 is not limited to a plate shape, and may be a plane shape or a mesh shape with a large number of holes. The shape and size of each partition member 3 may be different for each partition member 3.

[0039] (Support part) As shown in FIG. 2, the container body 2 has at least one support structure 24 that supports the partition member 3. One support structure 24 can support one partition member 3. The container body 2 of this embodiment has a plurality of support structures 24 positioned at intervals in the vertical direction. The partition member 3 is supported by any one of the plurality of support structures 24, and is installed at any height. The container body 2 of this embodiment has three support structures 24 positioned at intervals in the vertical direction. The number of support structures 24 that the container body 2 has is not limited. For example, the container body 2 may have two or four or more support structures 24, or may have only one support structure 24.

[0040] As shown in FIG. 3A, each support structure 24 has a pair of left and right support parts 25 formed on each of the pair of first side walls 21. In each support structure 24, the pair of left and right support parts 25 are located at the same height. The container body 2 of this embodiment has three pairs of left and right support parts 25 formed on each of the pair of first side walls 21. That is, the container body 2 has first to third support parts 25 arranged at intervals in the up-down direction. The partition member 3 is installed in the container body 2 by having both end parts on the left and right sides supported from below by the pair of support parts 25.

[0041] Each support portion 25 has at least one mounting portion 250 that supports the partition member 3. As shown in Fig. 2, each support portion 25 of this embodiment has a plurality of protrusions 250 arranged at the same height in the front-rear direction as a plurality of mounting portions. That is, each side wall 21, 22 of this embodiment has a plurality of first protrusions 250, a plurality of second protrusions 250, and a plurality of third protrusions 250 that function as the first to third support portions 25, respectively.

[0042] Each protrusion 250 is formed on the inner surface of the first side wall 21 and protrudes inward from the first side wall 21. In each support portion 25, each protrusion 250 has the same shape and size. Each protrusion 250 is formed in a quadrangular pyramid shape such that the outer shape when viewed in a cross section perpendicular to the left-right direction (thickness direction of the first side wall 21) becomes smaller toward the tip of the protrusion 250.

[0043] 3B, each protrusion 250 has an upper surface 251 and a lower surface 252. The upper surface 251 is horizontal. The lower surface 252 is inclined so that the portion closer to the tip of the protrusion 250 is located higher. Each of the ends on both sides in the left-right direction of the partition member 3 is placed on the upper surfaces 251 of the multiple protrusions 250 of the corresponding first side wall 21 and is supported from below by these multiple protrusions 250.

[0044] The shape of each of the convex portions 250 is not limited. In addition, the mounting portion in this embodiment is the convex portion 250 formed on the inner surface of the first side wall 21, but is not limited thereto. For example, the mounting portion may be the lower surface of a recess formed on the inner surface of the first side wall 21 or the lower surface of a hole formed in the first side wall 21. FIGS. 9 and 10 show an example of the container 1 in which the mounting portion is the lower surface 216 of the recess 215. FIG. 11 shows an example of the container 1 in which the mounting portion is the lower surface 218 of the hole 217. In addition, the shape and size of each of the mounting portions 250 may be different for each mounting portion 250.

[0045] As shown in Fig. 2, each support portion 25 of this embodiment has three protrusions 250 arranged at the same height and spaced apart in the front-rear direction. Hereinafter, as necessary, among the three protrusions 250 formed on each support portion 25, the first, second, and third protrusions 250 counting from the front will be referred to as a front protrusion 250a, a middle protrusion 250b, and a rear protrusion 250c, respectively. Since each first side wall 21 of this embodiment has three support portions 25, it has a total of three front protrusions 250a, a total of three middle protrusions 250b, and a total of three rear protrusions 250c.

[0046] There is no limitation on the number of protrusions 250 included in each support portion 25. Each support portion 25 may have two or four or more protrusions 250, or may have only one protrusion 250.

[0047] The three front protrusions 250a of each first side wall 21 are formed in the front part of the first side wall 21. The three front protrusions 250a of each first side wall 21 are located rearward as far as the front protrusions 250a located below. The three middle protrusions 250b of each first side wall 21 are formed in the center of the first side wall 21 in the front-rear direction and are located rearward of the front protrusions 250a belonging to the same support part 25. The three middle protrusions 250b of each first side wall 21 are formed in the same position in the front-rear direction. The three rear protrusions 250c of each first side wall 21 are formed in the rear part of the first side wall 21 and are located rearward of the middle protrusions 250b belonging to the same support part 25. The three rear protrusions 250c of each first side wall 21 are located forward as far as the rear protrusions 250c located below.

[0048] When each second side wall 22 rotates relative to the bottom 20, each notch 220 of the second side wall 22 describes an arc-shaped movement locus centered on the rotation axis of the second side wall 22. As shown in Figs. 7 and 8, the three rear convex portions 250c of each first side wall 21 are located on the movement locus of the corresponding notch 220 when the rear second side wall 22 rotates relative to the bottom 20. For this reason, when the rear second side wall 22 rotates, the three rear convex portions 250c of each first side wall 21 pass through the corresponding notch 220 of the rear second side wall 22 and do not come into contact with the rear second side wall 22. Similarly, the three front convex portions 250a of each first side wall 21 are located on the movement locus of the corresponding notch portion 220 when the front second side wall 22 rotates relative to the bottom portion 20, and when the front second side wall 22 rotates, the three front convex portions 250a of each first side wall 21 pass through the corresponding notch portion 220 and do not come into contact with the front second side wall 22. In addition, the three intermediate convex portions 250b of each first side wall 21 are located rearward of the movement locus of the upper end of the front second side wall 22 when the front second side wall 22 rotates relative to the bottom portion 20, and are located forward of the movement locus of the upper end of the rear second side wall 22 when the rear second side wall 22 rotates relative to the bottom portion 20. Therefore, when the container body 2 is transformed from the assembled state to the folded state, and when the container body 2 is transformed from the folded state to the assembled state, when each first side wall 21 is in an upright state and each second side wall 22 rotates relative to the bottom 20, each second side wall 22 does not come into contact with any of the protrusions 250.

[0049] Each notch 220 of the second side wall 22 may come into contact with the protrusion 250 when the second side wall 22 rotates, and overcome the protrusion 250. Also, for example, in a case where the protrusion 250 is small enough that the second side wall 22 can overcome the protrusion 250 even if the second side wall 22 comes into contact with the protrusion 250 when the second side wall 22 rotates, the second side wall 22 may not have the notch 220.

[0050] Each partition member 3 is inserted into the inner region 23 of the container body 2 through an opening 26 formed at the upper end of the container body 2, for example, as shown in Figure 4A, and then, both left and right end portions of the partition member 3 are placed on a pair of supports 25 formed on a pair of first side walls 21, respectively, as shown in Figure 6A, and the partition member 3 is installed on the container body 2.

[0051] (Opening) The container body 2 has at least one opening 211 to facilitate installation of the partition member 3. In this embodiment, each first side wall 21 has a plurality of recesses 211 arranged at intervals in the vertical direction as a plurality of openings. Specifically, each first side wall 21 has two recesses 211. That is, each first side wall 21 in this embodiment has a first recess 211 and a second recess 211. The two recesses 211 formed in one first side wall 21 and the two recesses 211 formed in the other first side wall 21 are formed at the same height and have a bilaterally symmetrical shape.

[0052] Each recess 211 is formed on the inner surface of the first side wall 21. As shown in FIG. 2, each recess 211 is a groove extending linearly in the front-rear direction. Each recess 211 extends from the front to the rear of the first side wall 21. Of the two recesses 211 of the first side wall 21, the recess 211 located on the lower side is a recess 211 used when placing the partition member 3 on the support structure 24 located at the lowest position, and is located between the multiple convex portions 250 of the support part 25 located at the lowest position and the multiple convex portions 250 of the support part 25 located at the second lowest position. Of the two recesses 211 of the first side wall 21, the recess 211 located on the upper side is a recess 211 used when placing the partition member 3 on the support structure 24 located at the second lowest position, and is located between the multiple convex portions 250 of the support part 25 located at the second lowest position and the multiple convex portions 250 of the support part 25 located at the third lowest position.

[0053] 3A and 3B, each recess 211 is located above and outside the multiple protrusions 250 of the support portion 25 located immediately below, and opens toward the upper region. Each recess 211 has a lower surface 212 which is the lower surface of the recess 211, and an upper surface 213 which is the upper surface of the recess 211.

[0054] The lower surface 212 is a surface that extends inward from the lower edge of the rear surface of the recess 211, and the orientation of this surface includes an upward component. The upper surface 213 is a surface that extends inward from the upper edge of the rear surface of the recess 211, and the orientation of this surface includes a downward component. In this embodiment, the lower surface 212 is inclined so that the portion closer to the inside is positioned lower, and the upper surface 213 is inclined so that the portion closer to the inside is positioned higher, and the inclination angle of the upper surface 213 with respect to the horizontal plane is larger than the inclination angle of the lower surface 212 with respect to the horizontal plane.

[0055] The shape of the recess 211 is not limited. For example, the two ends of the recess 211 in the front-rear direction in this embodiment are located inside the two ends of the first side wall 21 in the front-rear direction as shown in FIG. 2, but may be formed over the entire length of the first side wall 21 in the front-rear direction. The inclination angles of the lower surface 212 and the upper surface 213 of the recess 211 with respect to the horizontal plane are not limited. The opening of this embodiment is the recess 211 that does not penetrate the first side wall 21 in the left-right direction and has a back surface, but may be a hole that penetrates the first side wall 21 in the left-right direction. FIGS. 11 and 12 show an example of a container 1 in which the opening is a hole 217. In the example shown in FIG. 11, the lower surface 218 of the hole 217 formed in the first side wall 21 is used as the mounting portion, and in the example shown in FIG. 12, the protrusion 250 formed in the first side wall 21 is used as the mounting portion.

[0056] 3B, the lower surface 212 of each recess 211 is located slightly above the upper surfaces 251 of the multiple protrusions 250 located immediately below, and there is a step between the lower surface 212 of each recess 211 and the upper surfaces 251 of the multiple protrusions 250 located immediately below. That is, the lower surface 212 of each recess 211 is connected to the upper surfaces 251 of the multiple protrusions 250 via step surfaces 214 extending in the vertical direction. The step surfaces 214 are vertical surfaces.

[0057] The step surface 214 may be formed when the mounting portion is constituted by the lower surface 216 of the recess 215 as shown in Fig. 9, or may be formed when the opening portion is constituted by the hole 217 as shown in Figs. 11 and 12. Each recess 211 is used when installing the partition member 3 on the support structure 24 located immediately below (i.e., the support structure 24 including the protrusion 250 connected via the step surface 214). For example, when the partition member 3 is supported by the second support structure 24 from the bottom as shown in Fig. 6A, the upper recess 211 of the two recesses 211 is used as shown in Figs. 4A to 5B.

[0058] The partition member 3 is installed in the container body 2, for example, as shown below. In the following description, one end of the partition member 3 in the left-right direction is referred to as one end 31, and the other end is referred to as the other end 32. In addition, when the partition member 3 is installed in the container body 2, the first side wall 21 supporting the one end 31 is referred to as the one first side wall 21, and the first side wall 21 supporting the other end 32 is referred to as the other first side wall 21.

[0059] First, as shown in Figures 4A and 4B, the user places the partition member 3 from above the container body 2 in the inner region 23 of the container body 2 in a tilted state so that one end 31 is located lower than the other end 32, and inserts one end 31 into the recess 211 of one of the first side walls 21. In this case, the one end 31 is inserted higher and further outward than the state shown in Figure 6A in which the partition member 3 is installed in the container body 2. In other words, the recess 211 has a space in which the one end 31 is inserted higher and further outward than the state shown in Figure 6A in which the one end 31 is installed in the container body 2.

[0060] Next, the user rotates the partition member 3 so that the other end 32 moves downward, using the one end 31 fitted in the recess 211 as a fulcrum, as shown in Figures 4A and 4B, and places the other end 32 on the support portion 25 (plurality of protrusions 250) of the other first side wall 21. As a result, the partition member 3 is in a provisionally supported state in which the one end 31 is supported by the lower surface 212 of the recess 211 of the one first side wall 21 and the other end 32 is placed on the support portion 25 of the other first side wall 22, as shown in Figures 5A and 5B. In this provisionally supported state, the partition member 3 is inclined with respect to the horizontal plane so that the one end 31 is positioned slightly above the other end 32.

[0061] Next, the user slightly moves the partition member 3 toward the other first side wall 21 while it is still placed on the support portion 25 of the other first side wall 22, and moves one end portion 31 of the partition member 3 out of the recess 211 and places it on the support portion 25 (plurality of protrusions 250) of the one first side wall 21. As a result, the partition member 3 is installed on the container body 2 in a horizontal state in which one end portion 31 is placed on the support portion 25 of the one first side wall 21 and the other end portion 32 is placed on the support portion 25 of the other first side wall 22, as shown in Figures 6A and 6B.

[0062] The container 1 of this embodiment can be installed in the container body 2 by placing the partition member 3 on a plurality of protrusions 250 formed on the inner surface of each first side wall 21. In this case, the left-right distance between the protrusions 250 of one first side wall 21 on which the partition member 3 is placed and the protrusions 250 of the other first side wall 21 is shorter than the left-right dimension of the partition member 3, so that the left and right ends of the partition member 3 are easily stably supported by the left and right protrusions 250 and are unlikely to fall off the left and right protrusions 250. Therefore, the partition member 3 can be installed in a stable state. In addition, when installing the partition member 3 in the container body 2, the one end 31 of the partition member 3 can be inserted once into the recess 211 of the one first side wall 21 as described above, and then the left and right ends of the partition member 3 can be placed on the left and right protrusions 250. In this case, by inserting one end 31 of the partition member 3 into the recess 211, the other end 32 of the partition member 3 is less likely to come into contact with the other first side wall 21. Therefore, even though the length of the partition member 3 in the left-right direction is approximately the same as the distance between the pair of first side walls 21, the partition member 3 can be easily installed in the container body 2.

[0063] In the example shown in Figures 4A to 5B, the recess 211 in the first side wall 21 on the left side is utilized to install the partition member 3, but the partition member 3 may also be installed in the container body 2 in a similar manner by utilizing the recess 211 in the first side wall 21 on the right side.

[0064] The upper surface 213 of the recess 211 in this embodiment is inclined so that the closer to the inside of the container body 2, the higher the position. Therefore, when the above-mentioned partition member 3 is installed, one end 31 of the partition member 3 can be easily inserted into the recess 211. In addition, the lower surface 252 of the protrusion 250 in this embodiment is located higher as the closer to the inside of the container body 2. Therefore, when inserting one end 31 of the partition member 3 into the recess 211, the one end 31 of the partition member 3 is prevented from contacting the protrusion 250 above the recess 211, and in this respect, one end 31 of the partition member 3 can be easily inserted into the recess 211. In addition, when removing the partition member 3 installed in the container body 2, the partition member 3 is less likely to get caught on the protrusion 250 because the lower surface 252 of the protrusion 250 is an inclined surface, and the partition member 3 can be easily removed from the container body 2.

[0065] 6A and 6B, when the partition member 3 is installed in the container body 2, each of the left and right end faces of the partition member 3 faces a step surface 214 connecting the upper surface 251 of the convex portion 250 of the corresponding first side wall 21 and the lower surface 212 of the concave portion 211, and movement in the left and right direction is restricted by these step surfaces 214. Therefore, the partition member 3 can be installed in the container body 2 in a more stable state.

[0066] In this embodiment, there is a step between the lower surface 212 of the recess 211 and the upper surface 251 of the protrusion 250, but there may be no step between the lower surface 212 of the recess 211 and the upper surface 251 of the protrusion 250, for example, by connecting the lower surface 212 of the recess 211 and the upper surface 251 of the protrusion 250. Also, as shown in Fig. 10, when the mounting portion is formed by the lower surface 216 of the recess 215, there may be no step. In the example shown in Fig. 10, the back surface of the recess 215 and the lower surface 216 of the recess 215 are connected via an inclined surface 219 that is inclined so as to be positioned lower as it goes inward.

[0067] Furthermore, for example, each of the corner formed by the lower surface and the left end surface of the partition member 3 and the corner formed by the lower surface and the right end surface of the partition member 3 may be inclined so that the closer to the outside of the partition member 3 in the left-right direction, the higher the position. In this case, by utilizing the inclined surface of the partition member 3, it becomes possible to easily move the end of the partition member 3 from the state in which it is disposed in the recessed portion 211 to the upper surface of the protruding portion 250.

[0068] Furthermore, an engagement protrusion may be formed on the upper surface of each mounting portion (convex portion 250), and an engagement recess into which each engagement protrusion engages may be formed on the lower surface of the partition member 3. In this case, when the partition member 3 is placed on the container body 2, each engagement protrusion engages with the corresponding engagement recess, so that the pair of first side walls 21 of the container body 2 are connected via the partition member 3. This prevents swelling of each first side wall 21 of the container body 2, and prevents the end of the partition member 3 from falling off the mounting portion.

[0069] Furthermore, the first side wall 21 may have a plurality of recesses 211 formed at intervals in the front-rear direction, and a plurality of protrusions that can be inserted into the plurality of recesses may be formed on the left-right end face of the partition member 3. In this case, as shown in Fig. 2, it is possible to suppress a decrease in the rigidity of the first side wall 21 compared to a case in which the recesses 211 are formed over substantially the entire length of the first side wall 21 in the front-rear direction. In this case, each of the plurality of recesses formed at intervals in the front-rear direction may be a hole that penetrates the first side wall 21 in the left-right direction.

[0070] Furthermore, the design of the container 1 of this embodiment can be modified as appropriate. For example, the shape, size, number, material, etc. of each element of the container 1 may be modified as appropriate.

[0071] (2) Description As is clear from the above-described embodiment, the container (1) of the first aspect has the following configuration. The container (1) includes a container body (2) that opens upward, and a partition member (3) that divides the inner area (23) of the container body (2) into upper and lower parts. The container body (2) has a pair of opposing side walls (first side walls 21). Each of the pair of side walls (21) has a support portion (25) that supports the partition member (3). At least one of the pair of side walls (21) has a mounting portion (convex portion 250) formed on the side wall (21) and on which an end of the partition member (3) is placed and functions as the support portion (25), and an opening (recess 211) formed on the side wall (21), opening toward the inside, and into which the end (one end 31, the other end 32) of the partition member (3) can be inserted above and outside the state in which the partition member (3) is placed on the mounting portion.

[0072] According to this embodiment, when installing the partition member (3) in the container body (2), the end portion of the partition member (3) can be inserted into the opening (211) once, and then the partition member (3) can be placed on the placement portion (250). Therefore, the partition member (3) can be easily installed in the container body (2).

[0073] The container (1) of the second embodiment can be realized by combining with the container (1) of the first embodiment. In the second embodiment, the lower surface of the opening (211) is located higher than the upper surface (251) of the mounting portion (250), and there is a step between the lower surface (212) of the opening (211) and the upper surface (251) of the mounting portion (250).

[0074] According to this embodiment, with the ends (31, 32) of the partition member (3) supported on the mounting portion (250), the end face of the partition member (3) faces the step surface (214) formed between the lower surface (212) of the opening (211) and the upper surface (251) of the mounting portion (250), and the movement of the ends (31, 32) of the partition member (3) toward the opening (211) is restricted by the step surface (214). Therefore, the partition member (3) can be installed in the container body (2) in a more stable state.

[0075] The container (1) of the third aspect can be realized by combining with the first or second aspect. The third aspect has the following configuration. Each of the pair of side walls (21) has a first support part (25) that is a support part (25) and a second support part (25) that is arranged at an interval in the vertical direction. At least one of the pair of side walls (21) has a second placement part (250) formed on the side wall (21) and on which an end part of the partition member (3) is placed and functions as the second support part (25), and a second opening part (211) formed on the side wall (21), opening toward the inside, and into which the end parts (31, 32) of the partition member (3) can be inserted above and outside the state in which the end parts are placed on the second placement part (250).

[0076] According to this embodiment, the partition member (3) can be easily installed at different heights by utilizing the support portion (25) and the second support portion (25).

[0077] The container (1) of the fourth aspect can be realized by combining with any one of the first to third aspects. The fourth aspect has the following configuration. The placement portion is a convex portion (250) formed on the inner surface of the first side wall (21), which is the side wall. The container body (2) further has a bottom portion (20) having a rectangular shape in a plan view, and a pair of second side walls (22) different from the pair of first side walls (21). The pair of first side walls (21) are rotatably connected to a pair of opposing sides of the bottom portion (20), respectively, and the pair of second side walls (22) are rotatably connected to another pair of opposing sides of the bottom portion (20). At least one of the pair of second side walls (22) has a notch portion (220) formed at an end portion on the side of the first side wall (21) having the convex portion (250). When the second side wall (22) having the notch (220) rotates relative to the bottom (20), the protrusion (250) is located on a moving path of the notch (220).

[0078] According to this embodiment, the partition member (3) can be placed on the convex portion (250) formed on the inner surface of the side wall (21) and installed in the container body (2), so that the partition member (3) can be installed in a stable state. In addition, when the second side wall (22) rotates relative to the bottom portion (20), the convex portion (250) formed on the first side wall (21) passes through the notch portion (220) and does not come into contact with the second side wall (22), so that the second side wall (22) can rotate relative to the bottom portion (20) without any hindrance.
