Description

[Technical Field]

[0001] The present disclosure relates to a compartmented container having a partition wall that divides a space within the container. [Background technology]

[0002] Conventionally, as this type of partitioned container, a container in which a partition wall is attached to the container has been known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 57-172721 (Fig. 1, etc.) Summary of the Invention [Problem to be solved by the invention]

[0004] There is a demand for this type of compartmented container to accommodate an increased variety of contents. [Means for solving the problem]

[0005] One aspect of the invention made to solve the above problem is a container including: a lower partition wall that partitions a lower space within the container; an upper partition wall superimposed on the lower partition wall and extending the lower partition wall upward; The partitioned container includes engaging portions provided on the lower partition wall and the upper partition wall, which engage with each other in a concave-convex manner to restrict movement in the thickness direction of the walls. [Effects of the Invention]

[0006] According to one aspect of the present invention, the partition height differs depending on whether the space inside the container is divided by only the lower partition wall or by the upper partition wall stacked on top of the lower partition wall, so that an appropriate partition height can be selected depending on the type of contents. In other words, by making the partition height adjustable, it becomes possible to increase the number of types of contents that can be accommodated. [Brief explanation of the drawings]

[0008] [First embodiment] Figures 1 to 10 show a partitioned container 10 according to a first embodiment. As shown in Figure 1, the partitioned container 10 includes a container 11 and an upper partition wall 40, and can be changed between the state shown in Figure 1 in which the space inside the container is partitioned all the way to the top by the upper partition wall 40, and the state shown in Figure 2 in which the upper partition wall 40 is removed. Both the container 11 and the upper partition wall 40 are made of resin.

[0009] As shown in Figure 2, the container 11 is box-shaped with a rectangular top opening 11K, and has side walls 13 that stand up from the outer edges of a rectangular bottom wall 12. The connecting portions between adjacent side walls 13 are rounded. Hereinafter, when distinguishing between the side walls 13, the one located on the short side of the bottom wall 12 will be referred to as a short side wall 13A, and the one located on the long side of the bottom wall 12 will be referred to as a long side wall 13B.

[0010] 3, the side walls 13 extend downwardly beyond the bottom wall 12, and reinforcing ribs 12A are formed on the lower surface of the bottom wall 12 in a grid-like pattern and protrude from the area surrounded by the lower ends of the side walls 13. The lower ends of the reinforcing ribs 12A are located slightly above the lower ends of the side walls 13.

[0011] 2, the side wall 13 has an upper flange wall 14 that protrudes laterally from the upper end, a reinforcing flange wall 15 that is located slightly below the upper flange wall 14 and extends around the entire outer periphery of the container 11, and a lower flange wall 16 that protrudes from a height slightly below the bottom wall 12. The lower flange wall 16 is separated from the short side wall 13A at an intermediate portion. The upper flange wall 14, reinforcing flange wall 15, and lower flange wall 16 are connected by a plurality of vertical ribs 17.

[0012] As shown in Figures 2 and 3, the container 11 has a finger hook portion 18 with an open bottom surface formed by bulging the reinforcing flange wall 15 upward in the middle portion of the short side wall 13A, specifically in the range where the lower flange wall 16 in the horizontal direction is separated.

[0013] When the containers 11 are stacked one on top of the other, the lower end flange wall 16 of the upper container 11 abuts against the upper end flange wall 14 of the lower container 11, and the portion of the upper container 11 below the lower end flange wall 16 fits into the top opening 11K of the lower container 11.

[0014] 2 and 4, in the partitioned container 10 of this embodiment, a lower partition wall 20 that divides the lower space within the container 11 is integrally formed with the bottom wall 12 of the container 11 and is connected to the bottom wall 12 and side wall 13. Specifically, the container 11 has three lower short-side partition walls 21 that extend in the short-side direction of the container 11 and divide the interior of the container 11 into four sections in the long-side direction, and two lower long-side partition walls 22 that extend in the long-side direction of the container 11 and divide the interior of the container 11 into three sections in the short-side direction. The lower partition walls 20 have a height of approximately 1 / 5 to 1 / 6 of the height of the container 11, and their entire upper surfaces are flush. Note that a portion of the reinforcing rib 12A described above is arranged continuously with the lower partition wall 20 in the vertical direction, and the reinforcing rib 12A and the lower partition wall 20 improve the strength of the bottom wall 12.

[0015] The above-mentioned upper partition wall 40 can be stacked on the lower partition wall 20 from above to extend the lower partition wall 20 upward, thereby increasing the partition height that divides the inside of the container 11 (see FIG. 1). The lower partition wall 20 is provided with a lower engagement portion 25 (corresponding to the "first engagement portion" in the claims) that engages with the upper partition wall 40 in a concave-convex manner.

[0016] The lower engagement portion 25 has a pair of clamping portions 26 formed integrally with both side surfaces of the lower partition wall 20. As shown in Figures 2 and 5, the lower ends of the pair of clamping portions 26 are connected to the bottom wall 12, and the upper ends protrude above the upper edge of the lower partition wall 20. In addition, guide inclined surfaces 27 are formed at the upper ends of the pair of clamping portions 26 so as to move away from each other as they extend upward.

[0017] Some of the lower engagement portions 25 are side wall-side lower engagement portions 25A arranged in positions close to the side wall 13 of each lower partition wall 20, and the remainder are intermediate lower engagement portions 25B arranged in positions close to each intersection between the lower long side partition wall 22 and the lower short side partition wall 21. As a result, the lower engagement portions 25 are concentrated in positions close to the side wall 13 and at the intersections between the lower partition walls 20, and are not arranged in the center between the side wall 13 and the intersections or the center between the intersections.

[0018] 5 and 6, in this embodiment, the upper end of side wall-side lower engagement portion 25A is located higher than the upper end of intermediate lower engagement portion 25B, and the amount of protrusion from the upper edge of lower partition wall 20 of side wall-side lower engagement portion 25A is greater than that of intermediate lower engagement portion 25B. As a result, the depth of engagement of side wall-side lower engagement portion 25A with upper partition wall 40 is greater than the depth of engagement of intermediate lower engagement portion 25B with upper partition wall 40. Furthermore, the width of side wall-side lower engagement portion 25A in the direction sandwiching lower partition wall 20 is greater than the width of intermediate lower engagement portion 25B.

[0019] Furthermore, guide inclined surface 27 of sidewall-side lower engagement portion 25A is located higher than guide inclined surface 27 of intermediate lower engagement portion 25B, and the upper end of guide inclined surface 27 of intermediate lower engagement portion 25B is located at approximately the same height as the lower end of guide inclined surface 27 of sidewall-side lower engagement portion 25A. Furthermore, guide inclined surface 27 of sidewall-side lower engagement portion 25A has a larger range in the direction sandwiching lower partition wall 20 than guide inclined surface 27 of intermediate lower engagement portion 25B, and the upper end of guide inclined surface 27 of sidewall-side lower engagement portion 25A is located outward in the direction sandwiching lower partition wall 20 than the upper end of guide inclined surface 27 of intermediate lower engagement portion 25B.

[0020] As shown in FIG. 2, the upper end of the side wall 13 of the container 11 is formed at a position corresponding to above the lower partition wall 20 with a groove 13M that bulges outward and opens upward.

[0021] As shown in Figure 1, the partitioned container 10 has, as upper partition walls 40, upper short-side partition walls 41 that extend from the lower short-side partition walls 21 and upper long-side partition walls 42 that extend from the lower long-side partition walls 22. The upper short-side partition walls 41 and the upper long-side partition walls 42 are approximately the same height. The upper short-side partition wall 41 has short-side engagement grooves 41M that extend downward from the upper side (see Figure 7), while the upper long-side partition wall 42 has long-side engagement grooves 42M that extend upward from the lower side (see Figure 8). The length of the short side engagement groove 41M is approximately 1 / 4 to 1 / 5 of the height of the upper short side partition wall 41, while the length of the long side engagement groove 42M is approximately 3 / 4 to 4 / 5 of the height of the upper long side partition wall 42, and the lower end of the short side engagement groove 41M and the upper end of the long side engagement groove 42M are located at approximately the same height.

[0022] Then, by aligning the openings of the engagement grooves 41M, 42M with each other while the upper short-side partition wall 41 and the upper long-side partition wall 42 are perpendicular to each other, and inserting the opposing partition walls 42, 41 into the engagement grooves 41M, 42M, the upper short-side partition wall 41 and the upper long-side partition wall 42 can be engaged in an intersecting state.

[0023] 7 and 8, the upper short-side partition wall 41 and the upper long-side partition wall 42 have projections 41T and 42T that protrude laterally at the upper ends of both sides. The vertical distances from the lower ends of the upper short-side partition wall 41 and the upper long-side partition wall 42 to the projections 41T and 42T are approximately the same as the vertical distances from the upper edges of the lower short-side partition wall 21 and the lower long-side partition wall 22 of the container 11 to the groove portion 13M.

[0024] When the upper short-side partition wall 41 and the upper long-side partition wall 42 are attached to the container 11, the protrusions 41T, 42T fit into the groove 13M of the container 11, and the lower edges of the upper short-side partition wall 41 and the upper long-side partition wall 42 are clamped between the pair of clamping portions 26 of the lower engagement portion 25, thereby positioning the upper short-side partition wall 41 and the upper long-side partition wall 42 relative to the container 11. The lower edges of the upper short-side partition wall 41 and the upper long-side partition wall 42 correspond to the "second engagement portion" in the claims. In this embodiment, the engagement depth of the protrusions 41T, 42T with the groove 13M is greater than the engagement depth of the side wall-side lower engagement portion 25A with the upper partition wall 40.

[0025] The partitioned containers 10 can be stacked even with the upper partition wall 40 attached, and are configured so that when stacked, a space is created between the reinforcing rib 12A and side wall 13 of the upper partitioned container 10 and the upper partition wall 40 of the lower partitioned container 10.

[0026] The reinforcing rib 12A and side wall 13 of the upper partitioned container 10 may be configured to abut or be close to the upper partition wall 40 of the lower partitioned container 10. For example, it is possible to extend downward only the portion of the reinforcing rib 12A that overlaps with the upper partition wall 40. In this case, it is possible to prevent the upper partition wall 40 from bouncing off and distribute the load while ensuring a larger storage space than when the entire reinforcing rib 12A is made longer in the vertical direction.

[0027] The upper partitioned container 10 may also be configured so that the reinforcing rib 12A and the lower end of the side wall 13 are positioned lower than the upper end of the upper partition wall 40 of the lower partitioned container 10. In this case, the upper end of the upper partition wall 40 is positioned by providing notches in the reinforcing rib 12A and the side wall 13 that receive the upper partition wall 40. With this configuration, the lower end of the upper partitioned container 10 is closer to the contents, thereby preventing damage caused by the contents splashing.

[0028] Next, the effects of the partitioned container 10 of this embodiment will be described. The upper partition wall 40 is attached to the container 11, for example, as follows. First, the upper short-side partition wall 41 is aligned over the lower short-side partition wall 21 and then lowered. Then, the protrusion 41T begins to engage with the groove 13M of the container 11, and then the lower edge of the upper short-side partition wall 41 first begins to engage with the side-wall lower engagement portion 25A of the lower short-side partition wall 21. At this time, if the upper short-side partition wall 41 is misaligned in the plate thickness direction, the lower edge of the upper short-side partition wall 41 abuts against the guide inclined surface 27 of the side-wall lower engagement portion 25A and is guided between the pair of clamping portions 26.

[0029] Furthermore, when the upper short-side partition wall 41 is lowered, the lower edge of the upper short-side partition wall 41 also begins to engage with the intermediate lower engagement portion 25B of the lower short-side partition wall 21. At this time, even if the lower edge of the upper short-side partition wall 41 and the intermediate lower engagement portion 25B are misaligned due to bending of the upper short-side partition wall 41, the lower edge of the upper short-side partition wall 41 abuts against the guide inclined surface 27 of the intermediate lower engagement portion 25B and is guided between the pair of clamping portions 26. Then, the lower edge of the upper short-side partition wall 41 abuts against the upper edge of the lower short-side partition wall 21, and the two overlap vertically (see Figure 9).

[0030] Next, the upper long-side partition wall 42 is aligned over the lower long-side partition wall 22 and lowered with the engagement grooves 41M, 42M facing each other, deepening the engagement between the engagement grooves 41M, 42M and the upper long-side partition wall 42 and the upper short-side partition wall 41. After the protrusion 42T begins to engage with the groove 13M of the container 11, the lower edge of the upper long-side partition wall 42 reaches the side-wall lower engagement portion 25A of the lower long-side partition wall 22, and the two begin to engage. When the upper long-side partition wall 42 is further lowered, the lower edge of the upper long-side partition wall 42 engages with the lower intermediate engagement portion 25B and then abuts against the upper edge of the lower long-side partition wall 22, causing the upper long-side partition wall 42 and the lower long-side partition wall 22 to overlap vertically (see FIG. 10). When attaching the upper long side partition wall 42, the lower edge of the upper long side partition wall 42 is guided onto the lower long side partition wall 22 by the guide inclined surface 27. The lower edge of the upper partition wall 40 and the upper edge of the lower partition wall 20 correspond to the "mating surfaces" in the claims.

[0031] When removing the upper partition wall 40, for example, removal is completed by pulling out the upper long-side partition wall 42 and then pulling out the upper short-side partition wall 41. Note that the upper partition wall 40 may be attached to or detached from the container 11 in a state in which the upper long-side partition wall 42 and the upper short-side partition wall 41 are intersecting and engaged with each other.

[0032] According to the partitioned container 10 of this embodiment, the partition height differs when the container 11 is used alone (see FIG. 2) and when the upper partition wall 40 is stacked on top of the lower partition wall 20 (see FIG. 1), so that an appropriate partition height can be selected depending on the type of contents. In other words, by making the partition height adjustable, it becomes possible to increase the types of contents that can be stored.

[0033] Furthermore, upper partition wall 40 engages not only with groove 13M of container 11 but also with lower engagement portion 25 of lower partition wall 20, preventing upper partition wall 40 from shifting in the thickness direction relative to lower partition wall 20. Furthermore, in lower engagement portion 25, sidewall-side lower engagement portion 25A protrudes upward more than intermediate lower engagement portion 25B, so that when lowering upper partition wall 40 onto lower partition wall 20, if both ends are first aligned to engage with sidewall-side lower engagement portion 25A, then it naturally becomes easy to engage with intermediate lower engagement portion 25B as well, making the work easier than a configuration in which sidewall-side lower engagement portion 25A and intermediate lower engagement portion 25B are engaged at the same height at the same time.

[0034] Moreover, because the protrusions 41T, 42T begin to engage with the groove 13M of the container 11 before the upper partition wall 40 begins to engage with the side-wall lower engagement portion 25A, the upper partition wall 40 is less likely to shift when engaging with the side-wall lower engagement portion 25A. Also, if the upper partition wall 40 is shifted relative to the lower partition wall 20, the protrusions 41T, 42T abut against the upper flange wall 14 of the container 11 before the upper partition wall 40 begins to engage with the side-wall lower engagement portion 25A, making it possible to align the position by sliding it on the upper flange wall 14. Furthermore, because the groove 13M opens upward, it serves as a marker, making alignment easier.

[0035] Furthermore, clamping portion 26 of sidewall-side lower engagement portion 25A, which begins to engage first, is wider than clamping portion 26 of intermediate lower engagement portion 25B, and guide inclined surface 27 of sidewall-side lower engagement portion 25A is formed over a wider area, facilitating the operation of aligning upper partition wall 40. Here, it is conceivable to make clamping portion 26 of sidewall-side lower engagement portion 25A and clamping portion 26 of intermediate lower engagement portion 25B both wider and form both guide inclined surfaces 27 over a wider area, but intermediate lower engagement portion 25B, which begins to engage after sidewall-side lower engagement portion 25A, has a smaller misalignment with upper partition wall 40, and narrowing guide inclined surface 27 does not affect engagement, so by narrowing clamping portion 26 of intermediate lower engagement portion 25B, the amount of resin can be reduced, resulting in a lighter weight.

[0036] Furthermore, since the engagement depth of the side wall lower engagement portion 25A is relatively deep, even if the upper partition wall 40 tilts so that one end is raised, the one end is unlikely to come off the side wall lower engagement portion 25A.

[0037] Furthermore, by arranging sidewall-side lower engagement portion 25A in a position close to sidewall 13 of container 11 and by arranging intermediate lower engagement portion 25B near the intersection of lower partition walls 20, lower engagement portion 25 is not arranged in the center of each side of the partitioned rectangular space. As a result, when contents that are circular in plan view are placed in this partitioned space, the contents are less likely to interfere with lower engagement portion 25, preventing damage to the contents. Furthermore, the length of each side of the partitioned space can be adjusted to the diameter of the contents, allowing for a more compact design of partitioned container 10 than when lower engagement portion 25 is arranged in the center of each side.

[0038] The number of upper partition walls 40 can be selected and installed according to the contents. For example, only the upper long-side partition walls 42 or only the upper short-side partition walls 41 may be installed. Even in this case, the upper partition walls 40 engage with the lower partition walls 20 in a concave-convex manner, ensuring a stable installation state.

[0039] Furthermore, the upper partition wall 40 is more likely to bend at its upper edge than at its lower edge, which is intermittently clamped by multiple lower engagement portions 25, and it is thought that the upper short side partition wall 41, which has a short side engagement groove 41M that opens upward, is more likely to be damaged.However, in this embodiment, the short side engagement groove 41M that opens upward is shorter than the long side engagement groove 42M that opens downward, so the short side partition wall 41 is less likely to be damaged than if the short side engagement groove 41M and the long side engagement groove 42M were the same length.

[0040] [Second embodiment] A partitioned container 10W of this embodiment shown in FIG. 11 differs from the first embodiment in the configuration in which the upper partition wall 40 and the lower partition wall 20 engage with each other.

[0041] As shown in FIG. 12, in the container 11 of this embodiment, a plurality of recesses 20U are formed at a plurality of locations on the upper edge of the lower partition wall 20. Specifically, the recesses 20U are located in the portion of the lower partition wall 20 sandwiched between a pair of clamping portions 26, i.e., at both ends (portions connecting to the side walls 13) and near the intersections of the lower short-side partition wall 21 and the lower long-side partition wall 22. Meanwhile, as shown in FIGS. 11, 13, and 14, the upper partition wall 40 is formed with a plurality of protruding portions 40H (corresponding to "second engaging portions" in the claims) that enter the recesses 20U. This allows the upper partition wall 40 and the lower partition wall 20 to engage with each other in the extension direction as well. Note that the sides of the recesses 20U and the protruding portions 40H are both tapered.

[0042] As shown in FIGS. 12 and 15 , the upper ends of the clamping portions 26 of the sidewall-side lower engagement portions 25A and the intermediate lower engagement portions 25B are both located at the same height as the upper edge of the lower partition wall 20. The recessed portions 20U corresponding to the sidewall-side lower engagement portions 25A are formed deeper from the upper edge of the lower partition wall 20 than the recessed portions 20U corresponding to the intermediate lower engagement portions 25B. Corresponding to the difference in depth of the recessed portions 20U, the protruding portions 40H of the upper partition wall 40 that engage with the sidewall-side lower engagement portions 25A protrude more from the lower edge of the upper partition wall 40 than the protruding portions 40H that engage with the intermediate lower engagement portions 25B. As a result, in this embodiment as well, the engagement depth of the sidewall-side lower engagement portions 25A is deeper than the engagement depth of the intermediate lower engagement portions 25B.

[0043] According to this embodiment, since each clamping portion 26 does not protrude above the upper edge of lower partition wall 20, it is possible to place contents on lower partition wall 20 that are larger in plan view than the space partitioned by lower partition wall 20. The upper end of each clamping portion 26 may be located above the bottom surface of recess 20U and below the upper edge of lower partition wall 20.

[0044] [Other embodiments] In the above embodiment, the pair of clamping portions 26 are arranged on the lower partition wall 20, but they may also be arranged on the upper partition wall 40.

[0045] The pair of clamping portions may also be formed on the container 11. For example, the side wall lower engaging portion may protrude from the side wall 13 above the lower partition wall 20, and the intermediate lower engaging portion may protrude upward from the bottom wall 12 at a distance from the lower partition wall 20.

[0046] The pair of clamping portions 26 do not have to extend to the bottom wall 12 .

[0047] In the above embodiment, the lower partition wall 20 is integrally formed with the container 11, but it may be separate from the container 11. Furthermore, the lower partition wall 20 may be detachable from the container 11.

[0048] In the above embodiment, the lower partition wall 20 and the upper partition wall 40 are configured to intersect lengthwise and widthwise, but they may be configured to divide the container 11 only in one of the long side direction and the short side direction.

[0049] As shown in FIG. 16, a pin 50 may be provided on one end surface of the lower partition wall 20 and the upper partition wall 40, and a receiving hole 51 for receiving the pin 50 may be provided on the other end surface.

[0050] Each clamping portion 26 may be configured to abut against the contents to prevent rattle.

[0051] <Additional Notes> The following describes the features extracted from the above embodiment, while indicating, as necessary, the effects, etc. Note that, for ease of understanding, the corresponding configurations in the above embodiment are indicated in parentheses as appropriate below, but these features are not limited to the specific configurations indicated in parentheses.

[0052] [Feature 1] a lower partition wall (20) that partitions a lower space within the container (11); an upper partition wall (40) that is superimposed on the lower partition wall (20) and extends the lower partition wall (20) upward; A partitioned container comprising an engagement portion (25) provided on the upper partition wall (40) and the lower partition wall (20) or container (11), which engages with each other in a concave-convex manner to restrict movement in the thickness direction of the plates.

[0053] According to the partitioned container of Feature 1, the partition height differs depending on whether the space inside the container is divided by only the lower partition wall or by the upper partition wall stacked on top of the lower partition wall, so the appropriate partition height can be selected depending on the type of contents. In other words, by making the partition height adjustable, it is possible to increase the number of types of contents that can be stored. Moreover, because the upper partition wall engages with the lower partition wall or the container, the upper partition wall is prevented from shifting.

[0054] [Feature 2] The partitioned container according to Feature 1, wherein the first engaging portion (25) has a pair of clamping portions (26) that clamp the second engaging portion, which is disposed on the lower edge of the upper partition wall (40) or the upper edge of the lower partition wall (20).

[0055] [Feature 3] 3. The partitioned container according to Feature 2, wherein the pair of clamping portions (26) protrude beyond the overlapping surface of the lower partition wall (20) and the upper partition wall (40).

[0056] [Feature 4] One of the lower partition wall (20) and the upper partition wall (40) has a recess (20U) recessed from the overlapping surface of the lower partition wall (20) and the upper partition wall (40), The first engaging portion is disposed at a position corresponding to the recessed portion (20U), 3. The compartmented container according to claim 2, wherein the second engaging portion (40H) is received in the recessed portion (20U).

[0057] According to the partitioned container of Feature 2, the second engaging portion of the upper partition wall or the lower partition wall is sandwiched between the pair of sandwiching portions, so that the upper partition wall engages with the lower partition wall or the container. The pair of sandwiching portions may be configured to protrude beyond the overlapping surfaces of the lower partition wall and the upper partition wall, as in Feature 3, or may be configured to sandwich a recessed portion in one of the partition walls, as in Feature 4.

[0058] [Feature 5] The first engaging portion includes a sidewall-side first engaging portion (25A) adjacent to or close to the sidewall of the container (11), and an intermediate first engaging portion (25B) located inside the sidewall-side first engaging portion (25A) in the inward / outward direction of the container (11), A partitioned container according to any one of features 2 to 4, wherein the side wall side first engagement portion (25A) has a deeper engagement depth with the second engagement portion than the intermediate first engagement portion (25B).

[0059] According to the partitioned container of Feature 5, when the upper partition wall is placed on the lower partition wall, the side wall first engagement portion begins to engage first, and then the intermediate first engagement portion begins to engage, making the work easier than engaging both the side wall first engagement portion and the intermediate first engagement portion at once. Also, because the side wall first engagement portion has a relatively deep engagement depth, even if one end of the upper partition wall is tilted so as to be lifted, the side wall first engagement portion at that end is less likely to disengage from the second engagement portion.

[0060] [Feature 6] a guide inclined surface (27) for guiding the second engaging portion between the pair of clamping portions (26) is formed at the tip of the pair of clamping portions (26); A partitioned container according to Feature 5, wherein the guide inclined surface (27) of the side wall side first engagement portion (25A) is formed over a wider area in the direction sandwiching the second engagement portion than the guide inclined surface (27) of the intermediate first engagement portion (25B).

[0061] According to the partitioned container of feature 6, the guide inclined surface of the first engagement portion on the side wall, which begins to engage first, is formed over a relatively wide area, making it easy to align the position of the upper partition wall.

[0062] [Feature 7] The lower partition wall (20) and the upper partition wall (40) are orthogonal to each other vertically and horizontally, The partitioned container according to Feature 5 or 6, wherein the intermediate first engagement portions (25B) are concentrated at the intersections between the lower partition walls (20) or the upper partition walls (40), and are not arranged in the center between the intersections.

[0063] According to the partitioned container of Feature 7, when contents that are circular in plan view are placed in the partitioned space, they are less likely to interfere with the intermediate first engagement portion, preventing damage to the contents. In addition, the partitioned container can be designed more compactly than when the intermediate first engagement portion is located in the center between the intersecting portions.

[0064] Although the present specification and drawings disclose specific examples of the technology included in the scope of the claims, the technology described in the claims is not limited to these specific examples, but also includes various modifications and variations of the specific examples, and also includes parts of the specific examples taken out alone.
