A plurality of protrusions are provided vertically on the inner surface of the container body, and the upper protrusions and the lower protrusions are provided at different positions in the horizontal direction. The partition is provided with a notch at a position corresponding to the upper protrusion provided on the container body, and is placed on the upper protrusion or the lower protrusion by turning it inside out. <000001​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​To solve the above problems, a container according to one aspect of the present invention comprises a container body including a bottom wall component and opposing first side walls, and a partition that can be installed on the container body, wherein one of the first side walls and the other first side wall have a plurality of protrusions that project inward and are spaced apart in the vertical direction, and the partition includes a first end that can be placed on the protrusions of the one first side wall and a second end that can be placed on the protrusions of the other first side wall, and when the partition is rotated with the first end placed on the lower protrusion located below the protrusions, the second end does not come into contact with the upper protrusion located at a higher position than the lower protrusion of the other first side wall, or even if it comes into contact with the upper protrusion, it can move over it and be placed on the lower protrusion, and the lower protrusions of the one first side wall and the lower protrusions of the other first side wall are located at the same height. [Effects of the Invention]

[0007] According to one aspect of the present invention, it is possible to provide a container that is easier to install partitions in than conventional containers. [Brief explanation of the drawing]

[0008] [Figure 1] This is an exploded view of a container according to one embodiment of the present invention, and a perspective view showing that the container body is foldable. [Figure 2] This is a cross-sectional view taken along the cutting line AA' of the container body shown in Figure 1. [Figure 3] This is a cross-sectional view of the container body shown in Figure 1 with the partitions placed inside, viewed from the direction of the arrow along the cutting line BB' shown in Figure 1. [Figure 4] The cross-sectional view shown in Figure 3 illustrates the initial stage in which the partition is installed in the container body. [Figure 5] The cross-sectional view shown in Figure 3 represents a more advanced stage in the installation process compared to Figure 4, where the partition is installed in the container body. [Figure 6] This diagram illustrates variations in the placement of partitions in the container shown in Figure 1. [Figure 7] This is a perspective view of the container body and partition of a container according to another embodiment of the present invention, in which the container body is shown with some of the side walls removed for the sake of explanation. [Figure 8] Figure 7 shows a cross-sectional view of the container along the cutting line CC', illustrating the process of installing a partition in the container body. [Modes for carrying out the invention]

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

[0010] The container 1 of this embodiment comprises a container body 2 and a partition 3 that can be installed on the container body 2, as shown in Figure 1. The container body 2 is a box-shaped structure with an opening at the top. The container body 2 is configured to be foldable, as shown in the lower part of Figure 1, but the present invention is not limited to this. That is, the container body 2 may be configured not to be foldable. The partition 3 is a plate-shaped structure, and by installing it in the storage space of the container body 2, the storage space can be divided into a space between the partition 3 and the bottom wall component 20 of the container body 2, and a space with the partition 3 as the bottom.

[0011] The container body 2 includes a bottom wall component 20, opposing first side wall components 21 and 22, and opposing second side wall components 23 and 24. One first side wall component 21 and the other first side wall component 22 are each connected to the bottom wall component 20. The first side wall components 21 and 22 constitute a part of the side wall of the box-shaped container body 2, as shown in the center of Figure 1, and are located opposite each other with the bottom wall component 20 in between. Similarly, the opposing second side wall components 23 and 24 are each connected to the bottom wall component 20. The second side wall components 23 and 24 constitute a part of the side wall of the box-shaped container body 2, as shown in the center of Figure 1, and are located opposite each other with the bottom wall component 20 in between. One second side wall portion 23 and the other second side wall portion 24 are adjacent to one first side wall portion 21 and the other first side wall portion 22, respectively.

[0012] The first side walls 21, 22 and the second side walls 23, 24 are all hinged to the bottom wall component 20. This allows the container body 2 to be folded by rotating each side wall component 21-24 so that it lies above the bottom wall component 20, as shown in the lower part of Figure 1. On the other hand, when the first side walls 21, 22 and the second side walls 23, 24 are raised from the folded state shown in the lower part of Figure 1, as shown in the center of Figure 1, the container is configured to maintain a connected state between adjacent side walls. For example, adjacent side walls are locked together by a locking function (not shown) to maintain the raised state between them. In the folded state shown in the lower part of Figure 1, the second side walls 23, 24 are sandwiched between the bottom wall component 20 and the first side walls 21, 22. In other words, the bottom wall component 20 is the lowest layer, and the second side wall components 23, 24 and the first side wall components 21, 22 are folded over in that order. Note that the order in which the second side wall components 23, 24 and the first side wall components 21, 22 are folded over may be reversed.

[0013] The container body 2 is provided with multiple protrusions to support the partition 3 at predetermined locations. Specifically, the container body 2 has multiple protrusions 211 to 213 on one first side wall 21 that project inward (negative X-axis direction) and are spaced apart in the vertical direction (Z-axis direction), and multiple protrusions 211 to 213 on the other first side wall 22 that project inward (positive X-axis direction) and are spaced apart in the vertical direction (Z-axis direction) (Figure 3). The partition 3 can be placed on the upper surfaces of these protrusions 211 to 213. As the protrusions 211 to 213 are provided at predetermined locations as will be described later, the storage space of the container body 2 is partitioned by the support of the partition 3 by these protrusions. The protrusions 211 to 213 will be described below with reference to Figure 2.

[0014] Figure 2 is a front view of the inner surface 21a of one of the first side walls 21. Three different protrusions 211 to 213 are provided on the inner surface 21a along the vertical (Z-axis direction). Hereinafter, of the three protrusions 211 to 213, the protrusion closest to the bottom wall component 20 and located furthest down (on the most negative side of the Z-axis) will be referred to as the first protrusion 211 (lower protrusion, lowest protrusion). The protrusion furthest from the bottom wall component 20 and located furthest up (on the most positive side of the Z-axis) will be referred to as the third protrusion 213 (upper protrusion, uppermost protrusion). The protrusion located between the first protrusion 211 and the third protrusion 213 will be referred to as the second protrusion (lower protrusion, intermediate protrusion) 212. Furthermore, the present invention is not limited to three locations along the vertical direction (Z-axis direction); there may be two locations with protrusions, or four or more locations with protrusions.

[0015] The first protrusions 211 are provided at four locations along the Y-axis on the inner surface 21a of one of the first side walls 21, as shown in Figure 2. In this embodiment, the first side walls 21 and 22 are longer in the horizontal direction than the second side walls 23 and 24, and the container body 2 is roughly rectangular in shape. Therefore, in the first side wall 21, which is longer in the horizontal direction, multiple first protrusions 211 are also provided in the intermediate portion in the Y-axis direction, preventing the placed partition 3 from bending.

[0016] Note that the first convex portion 211 is not limited to one first side wall portion 21, but is also provided on the inner surface 22a (FIG. 3) of the other first side wall portion 22. The first convex portion 211 on one first side wall portion 21 and the first convex portion 211 on the other first side wall portion 22 are provided at the same height (height along the Z axis). The first convex portion 211 on the inner surface 21a of one first side wall portion 21 and the first convex portion 211 on the inner surface of the other first side wall portion 22 are arranged at positions that are point-symmetrical about the center point of the container body 2 when the container body 2 is viewed from above. However, it is not limited to this, and it may be arranged at positions that are line-symmetrical with respect to the line of the Y axis passing through the center point of the container body 2 when the container body 2 is viewed from above.

[0017] The basic configuration of the second convex portion 212 is the same as that of the first convex portion 211. However, as shown in FIG. 2, the position of the second convex portion 212 is displaced by a predetermined distance in the horizontal direction with respect to the position of the first convex portion 211. This displacement contributes to the ability to realize the case where the partition 3 is placed on the first convex portion 211 and the case where the partition 3 is placed on the second convex portion 212 by simply changing the orientation of the partition 3 in relation to the arrangement position of the notch portion 30 of the partition 3 described later. Note that the partition 3 being configured in this way is not essential in the present invention, and thus the above-mentioned displacement is not essential either. That is, the positions of the first convex portion 211 and the second convex portion 212 may be aligned along the Z axis. Note that the second convex portion 212 is not limited to the inner surface 21a of one first side wall portion 21, but is also provided at the same height (height along the Z axis) on the inner surface 22a (FIG. 3) of the other first side wall portion 22. Also, similar to the first convex portion 211, the position provided on one first side wall portion 21 and the position provided on the other first side wall portion 22 are point-symmetrical or line-symmetrical.

[0018] The third convex portion 213 has the same basic configuration as the first convex portion 211. As shown in FIG. 2, the positions of the first convex portion 211 and the third convex portion 213 are aligned along the Z-axis. In other words, the position of the second convex portion 212 is displaced by a predetermined distance in the horizontal direction with respect to the position of the third convex portion 213. Note that the third convex portion 213 is provided not only on the inner surface 21a of one of the first side wall portions 21 but also on the inner surface of the other first side wall portion 22 at the same height (height along the Z-axis). Further, similar to the first convex portion 211, the positions provided on one of the first side wall portions 21 and the positions provided on the other first side wall portion 22 are point-symmetric or line-symmetric.

[0019] Here, an enlarged view of the portion surrounded by the two-dot chain line in FIG. 2 is shown. Each of the above convex portions 211 to 213 includes surfaces 51 to 53 along the protruding direction except for the upper surface. Among these, the side surface 51 facing one of the second side wall portions 23 is inclined so as to gradually separate from one of the second side wall portions 23 toward the protruding tip side. Also, the side surface 52 facing the other second side wall portion 24 is inclined so as to gradually separate from the other second side wall portion 24 toward the protruding tip side. Further, the lower surface 53 facing the bottom wall component 20 is inclined so as to gradually separate from the bottom wall component 20 toward the protruding tip side.

[0020] Since the surfaces 51 to 53 are inclined in this way, when taking out the articles stored in the storage space of the container body 2, the articles are less likely to be damaged by the convex portions 211 to 213. In particular, the side surfaces 51 and 52 of the convex portions 211 to 213 near the second side wall portions 23 and 24 are less likely to interfere with the second side wall portions 23 and 24 when folding or assembling the container body 2 as shown in FIG. 1. Further, when folding or assembling by rotating the second side wall portions 23 and 24, the first side wall portions 21 and 22 are guided to open outward (in the X-axis direction), so that even if the convex portions 211 to 213 are provided, the folding or assembling operation is easy. In particular, the lower surfaces 53 of the second convex portion 212 and the third convex portion 213 do not interfere with the partition 3 inserted in the installation of the partition 3 as will be described later.

[0021] As shown in Figure 2, one of the first side walls 21 has an inner surface 21a with a recess 21b extending along the Y-axis direction above the first protrusion 211. The same recess 21b is also provided on the other first side wall 22 at the same height as the recess 21b. The recess 21b will be described later.

[0022] In this embodiment, the same material is used for one first side wall portion 21 and the other first side wall portion 22. In this case, the commonality between one first side wall portion 21 and the other first side wall portion 22 is achieved, which makes it possible to improve the manufacturing process of the container body 2 (first side wall portions 21 and 22), improve storage efficiency, and reduce costs.

[0023] As shown in Figure 1, partition 3 has a rectangular shape to match the shape of the storage space in the container body 2, and notches 30 are provided at the first end 31 and the second end 32, which are a pair of ends along the long side (Y axis).

[0024] Figure 3 shows the partition 3 placed on the upper surface of the first protrusion 211. Figure 3 is a cross-sectional view taken along the cutting line BB' shown in Figure 1, but it also shows enlarged cross-sectional views of two areas enclosed by dashed lines. As can be seen from the enlarged cross-sectional views, the position of the aforementioned first protrusion 211 on one first side wall 21 and the position on the other first side wall 22 are point-symmetric or line-symmetric. Therefore, the first protrusion 211 shown in the enlarged view in the lower left of Figure 3 is shown in cross-section, while the first protrusion 211 shown in the enlarged view in the lower right of Figure 3 is shown as a side view 52 rather than a cross-section.

[0025] The length of partition 3 along the X-axis is approximately the same as the width between the inner surface 21a of one first side wall 21 and the inner surface 22a of the other first side wall 22, or the length of partition 3 along the X-axis is slightly shorter.

[0026] Here, the aforementioned recesses 21b and 22b each include a first recess inner surface 410 and a second recess inner surface 420, respectively. The first recess inner surface 410 is a surface adjacent to the upper surface of the first protrusion 211 and is angled upward with respect to the Z-axis. The second recess inner surface 420 is a surface located above the first recess inner surface 410 and is angled downward. The first recess inner surface 410 is configured as a portion where the width between one first side wall portion 21 and the other first side wall portion 22 is widened outward. Therefore, in recesses 21b and 22b, more specifically in the region of the first recess inner surface 410 adjacent to the second recess inner surface 420, the width between one first side wall portion 21 and the other first side wall portion 22 is wider than the width between the inner surface 21a and the inner surface 22a. Thus, in recesses 21b and 22b, the space between the inner surfaces 410 of the first recesses between one first side wall portion 21 and the other first side wall portion 22 widens upward (in the positive Z-axis direction), and the inner surfaces 420 of the second recesses are connected to the inner surfaces 410 of the first recesses so as to widen outward (in the X-axis direction) downward (in the negative Y-axis direction), making it easier to rotate the partition 3 and place it on the upper surface of the first protrusion 211.

[0027] Furthermore, the width of the inner surface 410 of the first recess along the Z-axis is longer than the thickness of the partition 3 along the Z-axis. The angle of inclination of the inner surface 410 of the first recess diagonally upward, that is, the inclination angle with respect to the Z-axis, is equal to or greater than the inclination angle of the end face 33 of the partition 3 when the partition 3 is inclined as described later when installing the partition 3.

[0028] The installation of the partition 3 on the upper surface of the first protrusion 211 will be explained with reference to Figures 4 and 5. Here, the partition 3 includes a first end portion 31 (Figure 1) that can be placed on the first protrusion 211 (lower protrusion) of one of the first side walls 21, and a second end portion 32 that can be placed on the first protrusion 211 (lower protrusion) of the other first side wall 22, which is at the same height as the first protrusion 211. Then, as shown in Figure 4, in this placement, when the first end portion 31 is placed on the first protrusion 211 (lower protrusion) of one of the first side walls 21 and rotated with the first end portion 31 as the pivot point, the second end portion 32 does not come into contact with the second protrusion 212 and third protrusion 213 (upper protrusion, uppermost protrusion) of the other first side wall 22, which are located higher than the first protrusion 211 (lower protrusion) of the other first side wall 22, or if it does come into contact with them it goes over them and is placed on the first protrusion 211 (lower protrusion) of the other first side wall 22.

[0029] Figure 4 shows a state in which partition 3 is rotating near the third protrusion 213 of the other first side wall portion 22, with the second end portion 32 of partition 3 being the distal end of rotation. In this state, the second end portion 32 is separated from the third protrusion 213 of the other first side wall portion 22 and does not contact the third protrusion 213.

[0030] As shown in the enlarged cross-sectional view in the lower left of Figure 4, the first end portion 31 of the partition 3 rests on the first protrusion 211 of one of the first side walls 21, and becomes the pivot point. As mentioned above, in this state, the end face 33 on the first end portion 31 side is recessed into the recess 21b, and at least a part of the end face 33 is in contact with the inner surface 410 of the first recess. In other words, the partition 3 is positioned by at least a part of the end face 33 contacting the inner surface 410 of the first recess.

[0031] Figure 5 shows the partition 3 further rotated from Figure 4, with the second end portion 32 rotating near the second protrusion 212 of the other first side wall portion 22. In this state, the second end portion 32 is close to the second protrusion 212 of the other first side wall portion 22, but as shown in the enlarged cross-sectional view in the lower right of Figure 5, the notch portion 30 provided in the second end portion 32 prevents contact with the second protrusion 212, or allows it to move over it if it does come into contact. In other words, the notch portion 30 provided in the second end portion 32 passes through (is able to pass through) the second protrusion 212 of the other first side wall portion 22. As a result, the partition 3 rotates further to the state shown in Figure 3, with the second end portion 32 of the partition 3 resting on the upper surface of the first protrusion 211 of the first side wall portion 22.

[0032] The notch 30 is provided in the region of the second end 32 of the partition 3 that corresponds to the second protrusion 212 (upper protrusion) of the other first side wall 22 on the rotational trajectory with the first end 31 as the pivot point. In this embodiment, the container 1 is provided in the region corresponding to the position of the second protrusion 212 provided on one first side wall 21 and the other first side wall 22, respectively. That is, when placing the partition 3 on the first protrusion 211, the container 1 may be configured such that the second end 32 of the partition 3 is first placed on the first protrusion 211 of the other first side wall 22, and then rotated with the first end 31 as the distal end, using this as the pivot point. Even in this configuration, the notch 30 can pass through the second protrusion 212 (upper protrusion) of one first side wall 21. Even when the second end portion 32 is the pivot point, as shown in Figure 3, the recess 22b provided above the first protrusion 211 of the other first side wall portion 22 makes it possible to position the partition 3 on the first protrusion 211 of the other first side wall portion 22.

[0033] When placing the partition 3 on the third protrusion 213, the first end 31 or the second end 32 of the partition 3 is lifted and tilted so that one of the ends 31 or 32 is placed on the third protrusion 213 first, and then the partition 3 is rotated around this pivot point to be placed on the partition. Alternatively, the partition 3 may be lowered while in a horizontal position and placed on the third protrusion 213.

[0034] When placing partition 3 on the second protrusion 212, partition 3, as shown in Figures 3 to 5, is used in an inverted state with the Y-axis as the axis of rotation. By lowering partition 3 in this state horizontally from the opening side of the container body 2, the notch 30 passes through the third protrusion 213. As a result, partition 3 descends further without interfering with the third protrusion 213 and is placed on the second protrusion 212, which is horizontally offset from the third protrusion 213. Alternatively, instead of horizontally positioning partition 3, one end 31 or the second end 32 of partition 3 may be lifted and tilted so that one end 31 or 32 is placed on the second protrusion 212 first, and then rotated around this pivot point to place it on the partition. Alternatively, instead of inverting partition 3 to change its orientation, it may be rotated horizontally. Here, the front and back of partition 3 may be colored differently, or partially or entirely, so that the orientation in which it is placed can be easily seen at a glance. This serves as a marker in the form of inverting partition 3 vertically. Furthermore, by coloring each of the protrusions 211-213 and corresponding them to the color of the partition, the user can visually determine the vertical orientation of partition 3.

[0035] As described above, the storage space can be partitioned by placing the partition 3 on at least one of the first protrusion 211, the second protrusion 212, and the third protrusion 213. Figure 6 shows two types of partition configurations. For the sake of explanation, Figure 6 omits the other first side wall portion 22 and the other second side wall portion 24 shown in Figure 1, and hypothetically represents the partition 3. In the upper type of Figure 6, the partition 3 is placed on the first protrusion 211, and another partition 3 is placed on the third protrusion 213. With this type, the storage space can be partitioned into three sections: upper, middle, and lower. In the lower type of Figure 6, the partition 3 is placed only on the second protrusion 212, partitioning the storage space into two sections: upper and lower. Furthermore, although not shown in the diagram, the partition 3 can also be placed on the first protrusion 211, the second protrusion 212, and the third protrusion 213 to divide the space into four sections in the vertical direction (Z-axis direction). In this way, the storage space can be divided into different configurations simply by changing the placement position of the common partition 3. In other words, a container with excellent ease of installation of the partition 3 can be provided. The container body 2 and partition 3 are made of resin. The container body 2 is made of, for example, polypropylene, polyethylene, etc. The partition 3 is made of, for example, corrugated plastic (so-called corrugated plastic), resin sheet material, etc.

[0036] In this embodiment, the protrusions 211 to 213 are arranged on the inner surfaces 21a and 22a along the long sides of the container body 2. However, instead of this, or in addition, the protrusions 211 to 213 may be arranged on the second side walls 23 and 24 along the short sides of the container body 2.

[0037] In this embodiment, the protrusions 211 to 213 all have the same width in the horizontal direction, but this is not limited to this, and the first protrusion 211 may be wider than the other protrusions (the second protrusion 212 and the third protrusion 213). In this case, of the protrusions provided at intervals in the vertical direction, the two protrusions that sandwich one protrusion vertically are positioned such that one of the horizontal ends of each of the two protrusions is shifted horizontally by a predetermined distance from one of the horizontal ends of the first protrusion, and at least a portion of the two protrusions overlap when viewed from above. For example, the width of the wider first protrusion can be the sum of the width of the second protrusion 212 and the width of the third protrusion 213, in which case, when the container is viewed from above, the wider first protrusion overlaps with both the second protrusion 212 and the third protrusion 213. In other words, the third protrusion is positioned at a predetermined distance horizontally from the second protrusion, while the first protrusion is aligned with the second protrusion vertically and with the third protrusion vertically. However, not limited to this example, the width of the wide first protrusion may be longer than the sum of the width of the second protrusion 212 and the width of the third protrusion 213. Also, as a modification of the example in Figure 2, the number of first protrusions 211 may be greater than the number of second protrusions 212 and the number of third protrusions 213. This results in a configuration where partitions 3 are arranged on a large number of first protrusions, allowing for a well-balanced arrangement of partitions 3. Furthermore, the wide first protrusion may be provided near the adjacent point between one first side wall 21 and the other first side wall 22, that is, at the outer end of the first side wall. As a result, when the partition 3 is placed on the first protrusion, which is the lowest protrusion, the partition 3 can be supported at its outer end, allowing the partition 3 to be installed in a balanced manner.

[0038] [Embodiment 2] Other embodiments of the present invention are described below. For the sake of clarity, components having the same function as those described in the above embodiments will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0039] This second embodiment differs from the first embodiment in that the configuration of the partition 3 is different from that of the first embodiment described above, and furthermore, the configuration of the protrusions on the container body 2 is different from that of the first embodiment described above in accordance with the configuration of the partition 3.

[0040] Figure 7 is an exploded view of the container 1 of this embodiment, but for the sake of explanation, a portion of the side wall of the container body 2 is shown in a simplified manner. In this embodiment, the side walls on the short side of the roughly rectangular container body 2 are the first side walls 21 and 22, and the side walls on the long side are the second side walls 23 and 24. The protrusions 211 to 213 described in Embodiment 1 are provided on the first side walls 21 and 22. That is, the protrusions 211 to 213 project along the Y axis on the inner surfaces 21a and 22a of the first side walls 21 and 22, respectively (21a is not shown in Figure 7).

[0041] As shown in Figure 7, partition 3 has a structure connected by a hinge portion 6 provided between a first end 31 and a second end 32. Partition 3 is rotatable around the hinge portion 6 as the pivot point, with the region on the first end 31 side and the region on the second end 32 side being rotatable. The extension direction of the hinge portion 6 is configured to be parallel to the extension direction of the pivot point when partition 3 rotates around the first end 31 as the pivot point, i.e., the X-axis in Figure 7.

[0042] Each of the second side walls 23 and 24 of the container body 2 is provided with three auxiliary protrusions 230 (auxiliary protrusions 230a to 230c) that project inward, both above and below. Auxiliary protrusion 230a is provided at the same height as the first protrusion 211 of the first side walls 21 and 22. Auxiliary protrusion 230b is provided at the same height as the second protrusion 212 of the first side walls 21 and 22. Auxiliary protrusion 230c is provided at the same height as the third protrusion 213 of the first side walls 21 and 22. The three auxiliary protrusions 230a to 230c are arranged in a line in the vertical direction (Z-axis direction). The structure of each of the auxiliary protrusions 230a to 230c is the same as the structure of the first to third protrusions 211 to 213 (they also have structures corresponding to the lateral surfaces 51, 52 and the downward surface 53).

[0043] The installation of the partition 3 in this embodiment will be explained with reference to Figure 8. As shown in the upper container body 2(i) of Figure 8, the partition 3 is inserted into the storage space of the container body 2 in the negative Z-axis direction from the first end 31, and the partition 3 is advanced horizontally so that the first end 31 faces the first protrusion 211 of the first side wall 21. Next, with the first end 31 resting on the first protrusion 211 of one of the first side wall 21, the partition 3 is rotated around the first end 31 as the pivot point. This rotation places the hinge portion 6 on the auxiliary protrusion 230a, which is at the same height as the first protrusion 211. Alternatively, the first end 31 and the hinge portion 6 may be placed on the first protrusion 211 and the auxiliary protrusion 230a without rotation. This is shown in the container body 2(ii) of Figure 8.

[0044] As shown in the container body 2(ii) of Figure 8, when the hinge portion 6 is placed on the auxiliary projection 230a, the pivot point shifts to the hinge portion 6. Then, as shown in the container body 2(iii) of Figure 8, with the hinge portion 6 placed on the auxiliary projection 230a, the region on the second end portion 32 rotates with the hinge portion 6 as the pivot point, and the second end portion 32 is placed on the first projection 211 of the other first side wall portion 22. During this rotation, the second end portion 32 does not come into contact with the third projection 213 of the other first side wall portion 22, or if it does, it moves over it. As the rotation progresses and it approaches the second projection 212 of the other first side wall portion 22, the notch portion 30 passes through the second projection 212, so it does not come into contact with it, or if it does, it moves over it. Upon completion of the rotation, the partition 3 is placed on the first protrusion 211 of the container body 2, as shown in the lower container 1 of Figure 8.

[0045] According to this embodiment, the rotation radius of the partition 3 can be made smaller than in the embodiment 1. In Figure 8, the auxiliary protrusion 230 (230a) is located directly below the hinge portion 6, but the present invention is not limited to this. That is, the auxiliary protrusion 230 (230a) may be provided so as to be in the vicinity of the hinge portion 6 when the partition 3 is placed on top of it. For example, the auxiliary protrusions 230 (230a) may be provided on the left and right sides in the Y-axis direction, sandwiching the hinge portion 6.

[0046] In this embodiment, since the three auxiliary protrusions 230a to 230c are arranged vertically (along the Z-axis), when placing the partition 3 on the second protrusion 212, the partition 3 (the part from the hinge portion 6 to the end, or the partition 3 itself) is rotated to install it, as shown in Figure 8.

[0047] Furthermore, since the auxiliary protrusions 230 are provided at the same height as the first protrusions 211 to the third protrusions 213, when the partition 3 is placed on any of the first to third protrusions 211 to the third protrusions 213, the auxiliary protrusions 230, which are located at the same height, function as support members that prevent the partition 3 from bending or breaking.

[0048] In this embodiment, the hinge portion 6 is provided at an intermediate position in the partition, but the hinge portion may be provided closer to the end of the partition 3. Furthermore, multiple hinge portions may be provided.

[0049] Furthermore, the partition 3 equipped with the hinge portion 6 described in this embodiment can be used as the partition 3 of Embodiment 1.

[0050] Furthermore, different partitions may be used in combination with partition 3 described in Embodiment 1 or this embodiment (by changing the partitions placed on each level) (for example, Embodiment 1 and partition 3 of this embodiment may be combined, or partitions other than those in these forms may be combined).

[0051] Furthermore, the position and number of each protrusion are not limited. Also, the protrusions of Embodiment 1 and Embodiment 2 may be combined, or they may be used interchangeably (each protrusion and the auxiliary protrusion may be used interchangeably) (each protrusion may be provided on either the short side, the long side, or both).

[0052] 〔summary〕 A container according to embodiment 1 of the present invention comprises a container body including a bottom wall component and opposing first side wall components, and a partition that can be installed on the container body, wherein one of the first side wall components and the other first side wall component have a plurality of protrusions that project inward and are spaced apart in the vertical direction, and the partition includes a first end that can be placed on the protrusions of the one first side wall component and a second end that can be placed on the protrusions of the other first side wall component, and when the partition is rotated with the first end placed on the lower protrusion located below the protrusions, the second end does not come into contact with the upper protrusion located at a higher position than the lower protrusion of the other first side wall component, or if it comes into contact with the upper protrusion, it can be placed over it, and the lower protrusions of the one first side wall component and the lower protrusions of the other first side wall component are located at the same height.

[0053] According to the configuration of the above embodiment 1, it is possible to provide a container that is easier to install partitions in than conventional containers.

[0054] In the container according to aspect 2 of the present invention, in aspect 1, the partition is connected by a hinge portion provided between the first end and the second end, and the region from the hinge portion to the second end is rotatable about the hinge portion as the pivot point.

[0055] According to the configuration of the second embodiment described above, the hinge portion can be bent to easily place the partition on the lower protrusion. Since the rotation radius can be reduced, it is less likely to come into contact with the upper protrusion of the other first side wall when rotated.

[0056] A container according to embodiment 3 of the present invention, in embodiment 2, further includes opposing second side wall portions adjacent to each of the opposing first side wall portions, each of the opposing second side wall portions is provided with an auxiliary projection that protrudes inward at the same height as at least one of the downward projection portions of the first side wall portion, and the auxiliary projection is capable of supporting the hinge portion or the vicinity of the hinge portion.

[0057] According to the configuration of the above embodiment 3, the partition can be supported, thus reducing the reduction in the strength of the partition.

[0058] In the container according to aspect 4 of the present invention, in aspect 3, a plurality of auxiliary protrusions are provided at intervals in the vertical direction, the plurality of auxiliary protrusions are provided at the same height as the protrusions of the first side wall, and in the rotation, the partition is rotatable from the hinge to the second end, with the hinge being the pivot point, as an auxiliary protrusion of the second side wall that is at the same height as the lower protrusion supports the hinge or the vicinity of the hinge.

[0059] According to the configuration of the above embodiment 4, the partition can be easily rotated.

[0060] In the container according to embodiment 5 of the present invention, as in embodiments 1 to 4, a notch is provided in the partition in the region of the other first side wall that corresponds to the upward protrusion on the rotational trajectory.

[0061] According to the configuration of the above embodiment 5, the partition can be rotated without interfering with the upper protrusion, and the installation of the partition is easy.

[0062] In the container according to embodiment 6 of the present invention, in embodiment 5, the notches are provided at point-symmetrical or line-symmetrical positions between the first end and the second end of the partition, and each of the first side wall of one and the other first side wall is provided with two or more upper protrusions spaced vertically above the lower protrusion, and the second protrusion located on the lower side of the upper protrusions is positioned horizontally offset from the third protrusion located on the upper side, and when the partition is rotated, the second end does not come into contact with the third protrusion on the other first side wall, and the notch of the second end can pass through the second protrusion.

[0063] According to the configuration of embodiment 6 described above, it is possible to divide the storage space of the container body into four or more levels by providing three or more protrusions in the vertical direction, and the number of levels can be set as appropriate, such as dividing it into two or three levels, depending on the size of the storage space and its intended use. By rotating the partition horizontally or flipping it upside down (front and back) (changing its orientation), it is possible to place it on any protrusion or pass it through any protrusion. When there are three or more protrusions in the vertical direction, by combining the rotation of the partition and the changing of the orientation of the partition, the storage space can be divided into any number of levels using one or a small number of partitions.

[0064] A container according to embodiment 7 of the present invention, in embodiment 1, has three or more protrusions spaced apart vertically on one first side wall and the other first side wall, including a first protrusion that is the lower protrusion and is located closest to the bottom wall component, a third protrusion that is located furthest from the bottom wall component, and one or more second protrusions that are located between the first protrusion and the third protrusion and can become the lower protrusion, and of the protrusions spaced apart vertically, two protrusions that sandwich one protrusion vertically are positioned such that one of the horizontal ends of each of the two protrusions is shifted horizontally by a predetermined distance from one of the horizontal ends of the one protrusion, and at least a portion of the two protrusions overlap when viewed from above.

[0065] According to the configuration of embodiment 7, the storage space of the container body can be divided into three or more levels. Furthermore, according to the configuration of embodiment 7, of the protrusions provided at intervals in the vertical direction, two protrusions sandwiching one protrusion in the vertical direction are positioned at a predetermined distance horizontally from the one protrusion, and one of the horizontal ends of each of the two protrusions is positioned at a predetermined distance horizontally from one of the horizontal ends of the one protrusion. Therefore, compared to the case where all of the vertically spaced protrusions are positioned at predetermined distances horizontally, for example in a staircase shape, partitions can be placed on each protrusion in a relatively balanced manner. Note that in the configuration of embodiment 7, at least one of the horizontal ends of each of the two protrusions may satisfy the above configuration, and the other end may also satisfy the above configuration, but only one may satisfy the above configuration and the other may not.

[0066] [Additional Notes] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of Symbols]
