[0009] 1. One embodiment A container 9 according to one embodiment will be described with reference to the accompanying drawings. Directions such as up and down used in the following description are based on the state in which the container 9 according to one embodiment is placed on a horizontal surface, as shown in FIG.

[0010] (1) Overview of the container 1, a container 9 according to one embodiment includes a container body 1 having an internal space that is open upward, and a plurality of partition plates 2 that are detachably attached from above to the container body 1. Both the container body 1 and the plurality of partition plates 2 are molded products made of synthetic resin.

[0011] The partition plates 2 are attached to the container body 1 so as to be aligned in a row in the first direction D1 while maintaining an upright posture.

[0012] The container 9 has a first direction D1, a second direction D2, and a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to one another. In one embodiment of the container 9, the first direction D1 coincides with the longitudinal direction of the container 9, and the second direction D2 coincides with the lateral direction of the container 9. The third direction D3 coincides with the up-down direction.

[0013] When each partition plate 2 is attached to the container body 1, the thickness direction of each partition plate 2 coincides with the first direction D1 (i.e., the longitudinal direction of the container 9). The internal space of the container body 1 is divided into a plurality of spaces S1 by the plurality of partition plates 2 attached to the container body 1. At least one item is accommodated in each of the plurality of spaces S1. The type of item is not particularly limited.

[0014] (2) Container body The container body 1 has a bottom wall 11 (see FIG. 3) and a plurality of side walls 12 standing up from the outer peripheral edge of the bottom wall 11. The internal space of the container body 1 is a space surrounded by the bottom wall 11 and the plurality of side walls 12 of the container body 1. In one embodiment of the container 9, the bottom wall 11 and the plurality of side walls 12 are integrally molded from a synthetic resin, but the bottom wall 11 and the plurality of side walls 12 may also be molded separately.

[0015] The longitudinal direction of the container body 1 coincides with the longitudinal direction of the container 9, i.e., the first direction D1. Similarly, the short-side direction of the container body 1 coincides with the short-side direction of the container 9, i.e., the second direction D2. The up-down direction of the container body 1 coincides with the up-down direction of the container 9, i.e., the third direction D3.

[0016] The configuration of the container body 1 will be described in more detail below.

[0017] (2-1) Bottom wall 3, the bottom wall 11 has a rectangular flat plate-like outer shape. The longitudinal direction of the bottom wall 11 is a first direction D1, and the lateral direction of the bottom wall 11 is a second direction D2.

[0018] (2-2) Multiple side walls The multiple side walls 12 of the container body 1 include a pair of side walls 13 facing each other at a distance in the first direction D1 and a pair of side walls 14 facing each other at a distance in the second direction D2. The pair of side walls 13 and the pair of side walls 14 are integrally molded from synthetic resin. The side walls 13 and the side walls 14 are positioned alternately in the circumferential direction of the container body 1.

[0019] In the following description, for the sake of distinction, the side wall 13 will be referred to as a first side wall 13 and the side wall 14 will be referred to as a second side wall 14.

[0020] (2-3) First side wall A pair of first side walls 13 positioned at a distance in the longitudinal direction of the container body 1 are each a rectangular flat plate-shaped side wall.

[0021] (2-4) Second side wall A pair of second side walls 14, positioned at a distance in the short direction of the container body 1, are each rectangular flat side walls, and on the inner surfaces facing each other, multiple vertical groove portions 4 are formed in a row in the first direction D1.

[0022] (2-5) Vertical groove The plurality of vertical grooves 4 provided on each second side wall 14 are used to lock the plurality of partition plates 2 to each second side wall 14. The plurality of vertical grooves 4 are formed parallel to one another at intervals in the first direction D1.

[0023] In one embodiment of the container 9, the plurality of vertical grooves 4 provided on each second side wall 14 are three vertical grooves 4 aligned in the first direction D1. The plurality of partition plates 2 that can be attached to the container 9 are three partition plates 2.

[0024] The multiple vertical grooves 4 have the following common structure. However, the multiple vertical grooves 4 provided on one of the pair of second side walls 14 and the multiple vertical grooves 4 provided on the other second side wall 14 are formed in 180-degree rotational symmetry with respect to the central axis extending vertically of the container body 1.

[0025] As shown in Fig. 2, the vertical groove portion 4 includes an insertion groove 5 that forms the upper half of the vertical groove portion 4 and a storage groove 6 that forms the lower half of the vertical groove portion 4. The insertion groove 5 and the storage groove 6 are connected at positions where their central axes C5, C6 are offset from each other. The storage groove 6 extends downward from the insertion groove 5 via a step 7.

[0026] (2-6) Insertion groove The insertion groove 5 is configured so that an edge portion 214 (described later) of the partition plate 2 can be inserted from above. The insertion groove 5 opens at the upper end surface of the second side wall 14 and also opens at the inner surface of the second side wall 14. The insertion groove 5 is a groove that is open upward and inward.

[0027] The insertion groove 5 is formed so that its width in the first direction D1 decreases toward the lower portion. The opening area of ​​the insertion groove 5 in a horizontal cross section decreases toward the lower portion.

[0028] The insertion groove 5 has a first side surface 51 and a second side surface 52 that face each other in the first direction D1, and a third side surface 53 that connects the first side surface 51 and the second side surface 52. The third side surface 53 is an inner side surface that faces inward in the second direction D2. The first side surface 51, the third side surface 53, and the second side surface 52 are continuous to form a U-shape in a horizontal cross section.

[0029] The first side surface 51 is configured with an inclined surface 55 facing diagonally upward. The inclined surface 55 is a surface against which the edge portion 214 of the partition plate 2 slides, guiding the edge portion 214 of the partition plate 2 toward the storage groove 6. In one embodiment of the container 9, the entire first side surface 51 is configured with the inclined surface 55, but only a portion of the first side surface 51 may be configured with the inclined surface 55. The inclination of the inclined surface 55 is uniform, or the inclination may change stepwise or continuously.

[0030] The second side surface 52 includes a vertical surface 521 and an inclined surface 525. The majority of the second side surface 52 is made up of the vertical surface 521. The upper end of the second side surface 52 is made up of an inclined surface 525 that faces diagonally upward. The vertical surface 521 and the inclined surface 525 located above it are continuous vertically.

[0031] The third side surface 53 includes a vertical surface 531 and an inclined surface 535. The majority of the third side surface 53 is made up of the vertical surface 531. The upper end of the third side surface 53 is made up of an inclined surface 535 that faces diagonally upward. The vertical surface 531 and the inclined surface 535 located above it are continuous vertically.

[0032] (2-7) Storage groove The accommodating groove 6 is configured so that the edge portion 214 of the partition plate 2 can be inserted from above through the insertion groove 5. The accommodating groove 6 is open upward so as to communicate with the insertion groove 5, and is also open to the inside and outside of the second side wall 14. In other words, the accommodating groove 6 is formed so as to penetrate the second side wall 14 in the second direction D2.

[0033] The upper edge of the accommodating groove 6 includes an opening 60 communicating with the insertion groove 5 and a retaining portion 65 that forms a step 7 between the opening 60 and the insertion groove 5. The opening 60 and the retaining portion 65 are formed to be continuous in the first direction D1.

[0034] The opening 60 is formed wider in the first direction D1 than the edge 214 of the partition plate 2 so that the edge 214 can pass through in the vertical direction. The retaining portion 65 functions as a stopper that prevents the edge 214 of the partition plate 2 from accidentally coming loose.

[0035] The step 7 of the vertical groove portion 4 is formed between the inclined surface 55 of the insertion groove 5 and the retaining portion 65 of the accommodating groove 6. The inclined surface 55 and the retaining portion 65 intersect at an acute angle to form the step 7. Around the step 7, the accommodating groove 6 is wider in the first direction D1 than the insertion groove 5, with the step 7 separating them.

[0036] The central axis C5 of the insertion groove 5 and the central axis C6 of the storage groove 6 are offset from each other in the first direction D1. Here, the central axis C5 is the central axis of the insertion groove 5 at the lower end, and the central axis C6 is the central axis of the storage groove 6 at the upper end.

[0037] The lower edge of the accommodating groove 6 includes a locking recess 67. The locking recess 67 is a portion recessed downward from another portion 66 of the lower edge of the accommodating groove 6. The other portion 66 of the lower edge of the accommodating groove 6 is formed one step higher than the locking recess 67 on the lower edge of the accommodating groove 6.

[0038] A step is formed in the middle portion in the first direction D1 of the lower edge of the accommodating groove 6. A portion one step lower than the step is a locking recess 67 formed on one side in the first direction D1, and a portion one step higher than the step is another portion 66 formed on the opposite side from the one side in the first direction D1.

[0039] In the first direction D1, the side where the first side surface 51 (i.e., the inclined surface 55) is located relative to the second side surface 52 of the insertion groove 5, the side where the anti-slip portion 65 is located relative to the opening 60 at the upper edge of the accommodating groove 6, and the side where the locking recess 67 is located relative to the other part 66 of the accommodating groove 6 are aligned with each other.

[0040] The retaining portion 65 of the storage groove 6 is located above the locking recess 67 of the storage groove 6, and the opening 60 of the storage groove 6 is located above another portion 66 of the storage groove 6. In one embodiment of the container 9, the entire retaining portion 65 is located above the locking recess 67, but it is also possible for only a portion of the retaining portion 65 to be located above the locking recess 67.

[0041] The inclined surface 55 of the insertion groove 5 is located further above the retaining portion 65 of the storage groove 6. In one embodiment of the container 9, a portion of the inclined surface 55 of the insertion groove 5 is located above the retaining portion 65 of the storage groove 6, but the entire inclined surface 55 may be located above the retaining portion 65 of the storage groove 6.

[0042] (2-8) Engagement part As shown in FIGS. 3 and 4, the container body 1 further has a plurality of engagement portions 8 located above the bottom wall 11.

[0043] The multiple engagement portions 8 are two engagement portions 8 positioned at a distance in the second direction D2. The two engagement portions 8 engage with the lower end of the partition plate 2 located at the endmost position on one side of the first direction D1 (i.e., in the predetermined direction D1a) among the multiple partition plates 2, thereby preventing the partition plate 2 from coming off. For the sake of distinction, the endmost partition plate 2 will be designated by the symbol 2E below.

[0044] The two engaging portions 8 have the following common structure.

[0045] The engagement portion 8 extends from the bottom wall 11 of the container body 1. The engagement portion 8 includes a protruding piece-shaped support body 82 standing upright from the bottom wall 11, and an engagement body 84 protruding from the upper end of the support body 82. The engagement body 84 protrudes on the side opposite to one side of the first direction D1 (i.e., in the direction opposite to the predetermined direction D1a). The support body 82 and the engagement body 84 that constitute the engagement portion 8 are continuous to form an L shape.

[0046] The engaging body 84 is configured to abut from above against a protruding portion 22 (described below) provided at the lower end of the endmost partition plate 2E, and to engage from above with the protruding portion 22. The engaging portion 8 functions as a hook that catches on the endmost partition plate 2E.

[0047] (3) Divider Each of the plurality of partition plates 2 is detachably attached to the container body 1 to divide the internal space of the container body 1 in the first direction D1.

[0048] The plurality of partition plates 2 have a common structure as described below.

[0049] As shown in FIG. 4 and other figures, the partition plate 2 has a partition plate body 21 and a protruding portion 22 protruding from a lower portion of the partition plate body 21 to one side in the first direction D1 (that is, in a predetermined direction D1a).

[0050] In the container 9 of one embodiment, the partition plate body 21 and the protruding portion 22 are integrally molded using synthetic resin, but they may also be molded separately.

[0051] The configuration of the partition plate 2 will be described in more detail below.

[0052] (3-1) Partition plate body The partition plate main body 21 has an overall flat plate-like outer shape. When both end edge portions 214 of the partition plate main body 21 are engaged with the container body 1, the thickness direction of the partition plate main body 21 coincides with the first direction D1. The partition plate main body 21 has a first surface 211 and a second surface 212 that face opposite each other in the thickness direction.

[0053] (3-2) First page The first surface 211 of the partition plate main body 21 is a surface facing one side in the thickness direction of the partition plate main body 21, in other words, a surface of the partition plate main body 21 facing in a predetermined direction D1a.

[0054] (3-3)Second side The second surface 212 of the partition plate main body 21 is a surface facing the opposite side to one side in the thickness direction of the partition plate main body 21, in other words, a surface facing the opposite side to the predetermined direction D1a of the partition plate main body 21.

[0055] The first surface 211 and the second surface 212 of the partition plate main body 21 are preferably formed with 180-degree rotational symmetry about a central axis extending up and down of the partition plate main body 21. For example, if the first surface 211 of the partition plate 2 includes a flat region and an uneven region positioned side by side in the second direction D2, the second surface 212 also includes a similar flat region and uneven region positioned side by side in the second direction D2. In this case, it is preferable that the uneven region of the second surface 212 is positioned behind the flat region of the first surface 211, and the flat region of the second surface 212 is positioned behind the uneven region of the first surface 211.

[0056] (3-4) Edge Both end edge portions 214 of the partition plate body 21 protrude outward in the second direction D2 further than a main portion 210 (see FIG. 1) of the partition plate body 21. The main portion 210 is a portion of the partition plate body 21 excluding both end edge portions 214, and includes a first surface 211 and a second surface 212.

[0057] Both end edges 214 of the partition plate body 21 are inserted from above into the corresponding vertical grooves 4 and are engaged therewith, and each constitutes an engaging portion 28 of the partition plate 2. The engaging portions 28 on both sides of the partition plate 2 are flat portions that protrude from the top of the main portion 210 of the partition plate body 21 in directions away from each other in the second direction D2. The engaging portions 28 on both sides each have a rectangular cross-sectional shape that is long in the vertical direction. The cross-sectional shape here is a cross-sectional shape cut along a vertical plane perpendicular to the second direction D2.

[0058] (3-5)Protrusion The protruding portion 22 of the partition plate 2 is a portion that protrudes in a predetermined direction D1a from the lower portion of the partition plate main body 21. The protruding portion 22 is formed in a flat plate shape so that contents can be placed thereon. The protruding portion 22 has a flat surface facing upward. In one embodiment of the container 9, the upper surface of the protruding portion 22 is configured as a horizontal plane, but it is also possible for the upper surface of the protruding portion 22 to be configured as an inclined surface, an uneven surface, or a curved surface.

[0059] A recessed step 29 is further provided in the lower part of the partition plate main body 21 (see FIG. 4). The recessed step 29 is provided in a position adjacent to the protruding portion 22 in the first direction D1. In the partition plate 2, the orientation in which the protruding portion 22 is positioned relative to the recessed step 29 coincides with the predetermined direction D1a in which the protruding portion 22 protrudes.

[0060] When a plurality of partition plates 2 are attached in a row to the container body 1, the protrusion 22 of one of two adjacent partition plates 2 fits into the recessed step 29 of the other partition plate 2. This causes the lower parts of the two adjacent partition plates 2 to engage with each other.

[0061] At this time, the space S1 formed between two adjacent partition plates 2 is open upward. Below the space S1, a protruding portion 22 of one of the partition plates 2 is located. It is also preferable that at least one ventilation opening is formed in the protruding portion 22 so as to penetrate vertically.

[0062] It is also preferable that a hook protrudes downward from the lower end of the partition plate 2 for hooking onto the bottom wall 11 of the container body 1. In this case, it is preferable that a locking hole for hooking onto the hook of the partition plate 2 is formed penetrating from top to bottom in the bottom wall 11 of the container body 1. By having the above-mentioned hook on the partition plate 2, rattle of the partition plate 2 is suppressed and the partition plate 2 is prevented from coming off.

[0063] It is also preferable that, in addition to the hook, a protrusion protrudes downward from the lower end of the partition plate 2 to be inserted into the bottom wall 11 of the container body 1. In this case, it is preferable that a recess be formed in the bottom wall 11 of the container body 1, into which the protrusion of the partition plate 2 is inserted. By having the protrusion on the partition plate 2, rattling of the partition plate 2 is suppressed.

[0064] (4) Partition plate retaining structure The plurality of partition plates 2 attached to the container body 1 are prevented from coming off from the container body 1 by the above-described structure of the vertical grooves 4, respectively.

[0065] The locking portions 28 on both sides constituting both end edge portions 214 of each partition plate 2 are inserted into the storage grooves 6 below through the insertion grooves 5 of the corresponding vertical groove portions 4. At this time, the locking portions 28 of the partition plate 2 are in sliding contact with the inclined surfaces 55 of the insertion grooves 5, and are smoothly guided into the storage grooves 6.

[0066] Next, the locking portions 28 inserted into the accommodating grooves 6 are moved in a predetermined direction D1a, so that the lower ends of the locking portions 28 fit into the locking recesses 67 of the accommodating grooves 6. This positions each partition plate 2 relative to the container body 1.

[0067] As described above, the retaining portion 65 of the accommodating groove 6 is located above the locking recess 67 of the accommodating groove 6. In other words, the retaining portion 65, which functions as a stopper, is located above the locking portion 28 locked in the locking recess 67. Therefore, even if the locking portion 28 of the partition plate 2 lifts up from the locking recess 67 when the container 9 is subjected to vertical vibrations or when an impact is applied to the bottom surface of the container body 1, the locking portion 28 is prevented from accidentally coming out of the vertical groove portion 4.

[0068] Additionally, in one embodiment of the container 9, the lower portions of two adjacent partition plates 2 among the plurality of partition plates 2 engage with each other (see FIG. 4). That is, of the two adjacent partition plates 2, the protrusion 22 of one partition plate 2 fits into and engages with the recessed step 29 of the other partition plate 2. In the partition plate 2E located at the extreme end, the two engaging portions 8 of the container body 1 engage with its own protrusion 22. This prevents the partition plates 2 from accidentally coming off the container body 1 and also prevents the partition plates 2 from rattling.

[0069] 2. Variations The above-described embodiment is merely one of various embodiments of the present disclosure, and various modifications are possible depending on the design and the like as long as the object of the present disclosure can be achieved.

[0070] Various modified examples are listed below. The modified examples listed below can be applied in appropriate combinations. In the description of the modified examples, the same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

[0071] (First Modification) 5 and 6 show the main parts of a container 9 of a first modified example. In the container 9 of this modified example, a large number of partition plates 2 can be attached to the container body 1. The number of partition plates 2 that can be attached is not particularly limited, but is preferably in the range of 30 to 40, for example. In other words, the number of vertical grooves 4 formed on the inner surface of the second side wall 14 is preferably in the range of 30 to 40, for example. The number of vertical grooves 4 on each of the pair of second side walls 14 is preferably the same.

[0072] According to the container 9 of the first variant, it is possible to arrange thin items in the space S1 between two adjacent partition plates 2 in the first direction D1, and therefore it is possible to arrange a large number of thin items in the container 9.

[0073] (Second Modification) 7A shows a cross section of a main part of a container 9 of a second modified example. In this modified example, the first side surface 51 of the insertion groove 5 is configured as a vertical surface rather than an inclined surface 55. Even in this case, the locking portion 28 of the partition plate 2 can be inserted into the storage groove 6 below through the insertion groove 5 of the corresponding vertical groove portion 4.

[0074] 7B shows a cross section of a main part of container 9 of a third modified example. In this modified example, a protrusion 652 is provided on retaining portion 65 of storage groove 6. Protrusion 652 is formed so as to bulge downward at a portion of retaining portion 65 that is close to opening 60. By providing protrusion 652 on retaining portion 65, even if locking portion 28 of partition plate 2 lifts up from locking recess 67 due to vibration or the like, protrusion 652 catches on protrusion 652, thereby more effectively preventing locking portion 28 from accidentally coming off through opening 60.

[0075] (Third Modification) 8 shows a container 9 of a third modified example. The container 9 includes a container body 1 that is open upward, and a plurality of partition plates 2 that divide the internal space of the container body 1 in a first direction D1.

[0076] The container body 1 has a bottom wall 11 (see FIG. 9) that is rectangular in plan view, with a first direction D1 as the longitudinal direction and a second direction D2 as the lateral direction, and a plurality of side walls 12. The plurality of side walls 12 are two pairs of side walls 12, and more specifically, include a pair of first side walls 13 positioned opposite each other at a distance in the first direction D1, and a pair of second side walls 14 positioned opposite each other at a distance in the second direction D2.

[0077] 9 and other figures, the container body 1 further includes a pair of restriction walls 15 extending in the first direction D1. The pair of restriction walls 15 are provided on the inner sides of the upper portions of the pair of second side walls 14, respectively.

[0078] The structures of the pair of restriction walls 15 are plane-symmetrical with respect to a virtual plane perpendicular to the second direction D2. The common structure of the pair of restriction walls 15 will be described below.

[0079] The restriction walls 15 are positioned parallel to the corresponding second side walls 14. The restriction walls 15 are formed integrally with the corresponding second side walls 14 via connecting walls 16 (see FIGS. 10 and 11) extending in the first direction D1. The connecting walls 16 are connected to the lower edges of the restriction walls 15 so that the restriction walls 15 and the connecting walls 16 intersect in an L-shape in a vertical cross section.

[0080] 10 and 11, the restriction wall 15 is formed with a plurality of engagement recesses 154 for inserting the edge portion 214 of the partition plate 2 from above. The engagement recesses 154 are aligned at intervals (equally spaced in this modified example) in the first direction D1. The engagement recesses 154 are recessed downward from the upper end surface of the restriction wall 15. The engagement recesses 154 are open upward and on both sides in the second direction D2.

[0081] Additionally, a plurality of engagement holes 142 are formed on the inner surface of the upper portion of the second side wall 14 to engage with the edge portion 214 of the partition plate 2. The plurality of engagement holes 142 are aligned at intervals (equally spaced in this modified example) in the first direction D1. The engagement holes 142 have a shape that is recessed outward in the second direction D2 from the inner surface of the upper portion of the second side wall 14, and in this modified example, penetrate the upper portion of the second side wall 14 in the second direction D2.

[0082] The number of the engagement recesses 154 in the restriction wall 15 matches the number of the engagement holes 142 in the second side wall 14 corresponding to the restriction wall 15. The engagement recesses 154 and the engagement holes 142 are in one-to-one correspondence. Any of the engagement recesses 154 and the corresponding engagement hole 142 are positioned offset from each other in the first direction D1.

[0083] Next, the structure of the partition plate 2 will be described.

[0084] The plurality of partition plates 2 are detachably attached to the container body 1 to divide the internal space of the container body 1. The plurality of partition plates 2 have a common structure as described below.

[0085] As shown in Figures 10, 11 and 12, the edge portion 214 of the partition plate main body 21 is the part that is inserted from above into the corresponding engagement recess 154 of the regulating wall 10 and engaged, and constitutes the engagement portion 28 of the partition plate 2.

[0086] The edge portion 214 of the partition plate 2 is a portion that protrudes outward in the second direction D2 from the upper portion of the main portion 210 of the partition plate body 21, and has a vertically elongated cross-sectional shape. The cross-sectional shape here is a cross-sectional shape cut along a vertical plane perpendicular to the second direction D2.

[0087] An elastically deformable hook-shaped engaging portion 216 and a rib-shaped protrusion 218 are formed on an edge portion 214 of the partition plate 2 .

[0088] The engagement portion 216 is positioned offset in the first direction D1 with respect to the main body portion 210 of the partition plate 2. The engagement portion 216 is configured to elastically fit into a corresponding one of the multiple engagement holes 142 in the second side wall 14 from the inside in the second direction D2, and to elastically engage with the corresponding engagement hole 142. The engagement portion 216 includes an elastically deformable support portion 216a that extends downward, and a protrusion 216b that protrudes outward in the second direction D2 from the lower end of the support portion 216a. The protrusion 216b fits into the corresponding engagement hole 142, thereby preventing the partition plate 2 from coming off upward.

[0089] The rib-shaped protrusion 218 is composed of a protruding piece that protrudes from the edge 214 of the partition plate 2 to one side in the first direction D1. The rib-shaped protrusion 218 is configured to prevent the edge 214 from coming off by abutting against the side surface 156 of the restriction wall 15. The side surface 156 of the restriction wall 15 is the surface of the restriction wall 15 that faces the second direction D2 and is also the surface of the restriction wall 15 that faces the second side wall 14. The protrusion 218 is positioned offset in the first direction D1 with respect to the main body portion 210 of the partition plate 2. The side where the protrusion 218 is offset from the main body portion 210 in the first direction D1 and the side where the engagement portion 216 is offset from the main body portion 210 in the first direction D1 are opposite each other.

[0090] At the edge portion 214 of the partition plate 2, the engaging portion 216 and the protruding portion 218 are positioned offset from each other in the first direction D1. A distance is provided between the engaging portion 216 and the protruding portion 218 in the first direction D1, and the engaging portion 216 and the protruding portion 218 are positioned so as not to overlap each other in the first direction D1.

[0091] The positional relationship between the main body portion 210, the engagement portion 216, and the protrusion portion 218 of the partition plate 2 in the first direction D1 is not limited to this.

[0092] In other words, in the container 9 of the third modified example, the main portion 210, the engagement portion 216 and the protrusion portion 218 of the partition plate 2 are arranged at positions offset from each other in the first direction D1, but the main portion 210, the engagement portion 216 and the protrusion portion 218 of the partition plate 2 may also be arranged at the same position in the first direction D1.

[0093] The main body portion 210 and the engaging portion 216 of the partition plate 2 may be provided at the same position in the first direction D1, and the protrusion 218 may be provided at a position offset from the main body portion 210 and the engaging portion 216 in the first direction D1. Alternatively, the main body portion 210 and the protrusion 218 of the partition plate 2 may be provided at the same position in the first direction D1, and the engaging portion 216 may be provided at a position offset from the main body portion 210 and the protrusion 218 in the first direction D1. Alternatively, the engaging portion 216 and the protrusion 218 of the partition plate 2 may be provided at the same position in the first direction D1, and the main body portion 210 may be provided at a position offset from the engaging portion 216 and the protrusion 218 in the first direction D1.

[0094] Furthermore, in the container 9 of the third modified example, the engagement portion 216 and the protrusion portion 218 of the partition plate 2 are located on opposite sides of the main body portion 210, but the positional relationship is not limited to this, and the engagement portion 216 and the protrusion portion 218 of the partition plate 2 may be located on the same side of the main body portion 210.

[0095] Furthermore, at the edge portion 214 of the partition plate 2, the engaging portion 216 and the protruding portion 218 are positioned offset from each other in the second direction D2. In the second direction D2, a distance is provided between the engaging portion 216 and the protruding portion 218, and the engaging portion 216 and the protruding portion 218 are positioned so as not to overlap each other in the second direction D2. In the second direction D2, the engaging portion 216 is positioned outward from the protruding portion 218. In other words, in the second direction D2, the engaging portion 216 is positioned farther from the main body portion 210 of the partition plate 2 than the protruding portion 218.

[0096] 11, the inner surface of the engagement portion 216 in the second direction D2 and the outer surface of the protrusion 218 in the second direction D2 are both located on an imaginary straight line L1 in a horizontal cross section. The imaginary straight line L1 here is a straight line that is slightly inclined (for example, by an angle within a predetermined range greater than 0° and less than 10°) from the restriction wall 15 extending in the first direction D1 as a reference. The imaginary straight line L1 is inclined so that the closer it is to the restriction wall 15 in the first direction D1, the closer it is to the side of the engagement portion 216 where the protrusion 218 is located.

[0097] In the container 9 of the third modified example, as described above, the inner surface of the engaging portion 216 and the outer surface of the protruding portion 218 are positioned on the imaginary straight line L1 in the horizontal cross section, so that the engaging portion 216 and the protruding portion 218 can be molded using an upper and lower split mold when injection molding the partition plate 2. In other words, in the container 9 of the third modified example, the partition plate 2 having the engaging portion 216 and the protruding portion 218 can be molded using a simple mold that does not require a slide core or the like.

[0098] As described above, it is not essential that the inner surface of the engagement portion 216 and the outer surface of the protrusion 218 are positioned on the imaginary straight line L1 in the horizontal cross section. However, even if the inner surface of the engagement portion 216 and the outer surface of the protrusion 218 are not positioned on the imaginary straight line L1 in the horizontal cross section, it is preferable that the inner surface of the engagement portion 216 and the outer surface of the protrusion 218 are positioned at a distance from each other in the first direction D1 and the second direction D2 and have the same inclination (i.e., are parallel to each other). The inclination of the inner surface of the engagement portion 216 is such that the closer to the protrusion 218 in the first direction D1 the portion of the inner surface of the engagement portion 216 is, the closer to the restriction wall 15 the portion of the protrusion 218 is. The inclination of the outer surface of the protrusion 218 is such that the closer the portion is to the engagement portion 216 in the first direction D1, the more outward it is positioned in the second direction D2; in other words, the closer the portion is to the engagement portion 216 in the first direction D1, the more it is tilted away from the regulating wall 15.

[0099] According to the container 9 of the third modified example having the above-described configuration, the movement of the plurality of partition plates 2 attached to the container body 1 is effectively restricted in the first direction D1, the second direction D2, and the third direction D3.

[0100] In other words, in the container 9 of the third modified example, the edge portion 214 of the partition plate 2 is inserted from above into the engagement recess 154 of the regulating wall 15, thereby effectively restricting the movement of the partition plate 2 in the first direction D1 and preventing the partition plate 2 from shifting in position in the first direction D1.

[0101] In addition, in the container 9 of the third modified example, the engagement portion 216 provided on the edge portion 214 of the partition plate 2 elastically engages with the engagement hole 142 of the second side wall 14 of the container body 1, thereby effectively restricting movement of the partition plate 2 in the second direction D2 and the third direction D3 (especially upward movement), and preventing the partition plate 2 from coming loose.

[0102] Furthermore, in the container 9 of the third modified example, the rib-like protrusions 218 provided on the edge portion 214 of the partition plate 2 abut against the side surface 156 of the restricting wall 15 of the container body 1, restricting the partition plate 2 from moving in the second direction D2 away from the second side wall 14. This effectively prevents the engaging portions 216 of the partition plate 2 from accidentally coming off the engaging holes 142 of the second side wall 14.

[0103] Therefore, according to the container 9 of the third modified example, the partition plates 2 are prevented from accidentally coming off the container body 1, and the partition plates 2 are prevented from rattling.

[0104] (Other variations) In one embodiment of the container 9, the container body 1 is provided with two engagement portions 8, but the number of engagement portions 8 is not particularly limited, and one or three or more engagement portions 8 may be provided. In either case, one or more engagement portions 8 engage with the protrusion 22 of the partition plate 2E located at the extreme end, thereby preventing the partition plate 2E from accidentally coming off.

[0105] In one embodiment of the container 9, the engaging portion 8 is molded integrally with the bottom wall 11 using synthetic resin, but the engaging portion 8 may be molded separately from the bottom wall 11 (i.e., the container body 1). Also, the engaging portion 8 may be molded integrally with the first side wall 13 or the second side wall 14.

[0106] In one embodiment of the container 9, the protruding portion 22 is formed in a flat plate shape, but other structures may be employed as long as the contents can be placed on at least a portion of the protruding portion 22. For example, the protruding portion 22 may be configured as a group of protrusions including a plurality of ribs.

[0107] In one embodiment of the container 9, the retaining portion 65 of the storage groove 6 is composed of a horizontal flat surface facing downward, but is not limited to this, and for example, the retaining portion 65 may include at least one of a convex curved surface and a concave curved surface, or may include an inclined surface.

[0108] In one embodiment of the container 9, the protruding portion 22 of the partition plate 2 protrudes from the lower end of the partition plate main body 21, but this is not limited thereto, and the protruding portion 22 may protrude from the lower part of the partition plate main body 21. For example, the protruding portion 22 may protrude from a portion above the lower end of the partition plate main body 21.

[0109] In one embodiment of the container 9, the partition plate 2 has an L-shaped outer shape with a protrusion 22 protruding from the lower part of the partition plate main body 21 on one side in the longitudinal direction D1, but this is not limited to this and, for example, the partition plate 2 may have an inverted T-shaped outer shape with the protrusion 22 protruding from the lower part of the partition plate main body 21 on both sides in the longitudinal direction D1.

[0110] In one embodiment of the container 9, the protrusion 22 on one of the two adjacent partition plates 2 fits into the downwardly open recessed step 29 on the other partition plate 2, thereby engaging the lower parts of the two partition plates 2 together, but the structure for engaging the lower parts of the two partition plates 2 together is not limited to this.

[0111] For example, the protrusion 22 of one partition plate 2 may be configured to engage with a protrusion of the other partition plate 2. In this case, the protrusion of the other partition plate 2 is preferably provided above the lower end of the partition plate body 21.

[0112] Alternatively, the protruding portion 22 of one partition plate 2 may be configured to engage with the protruding portion 22 of the other partition plate 2. The partition plate 2 preferably has an inverted T-shaped outer shape in which the protruding portions 22 protrude from the lower portion of the partition plate body 21 on both sides in the longitudinal direction D1.

[0113] Alternatively, a structure may be adopted in which a protrusion provided on the protruding portion 22 of one partition plate 2 is inserted into and engaged with a hole provided in the other partition plate 2. In this case, it is preferable that the hole in the other partition plate 2 is provided in the partition plate body 21 so as to penetrate or not penetrate.

[0114] 3. Summary As described based on the above embodiment and various modified examples (particularly, as described based on the third modified example), a container 9 according to a first aspect of the present disclosure includes a container body 1 and a partition plate 2. The container body 1 has a bottom wall 11, a pair of first side walls 13 facing each other at a distance in a first direction D1, and a pair of second side walls 14 facing each other at a distance in a second direction D2 perpendicular to the first direction D1. The partition plate 2 is detachably attached to the container body 1 to divide the internal space of the container body 1. The container body 1 further includes a restricting wall 15 located on the inside of an upper portion of the second side wall 14, an engaging recess 154 formed in the restricting wall 15 for inserting an edge portion 214 of the partition plate 2 from above, and an engaging hole 142 formed on the inner surface of an upper portion of the second side wall 14. The edge portion 214 of the partition plate 2 has an engagement portion 216 that elastically engages with the engagement hole 142 of the second side wall 14, and a protrusion portion 218 that prevents the edge portion 214 from coming loose by abutting against the side surface 156 of the regulating wall 15 that faces the second side wall 14.

[0115] According to this embodiment, the edge portion 214 of the partition plate 2 is inserted into the engagement recess 154 of the restriction wall 15, thereby preventing the partition plate 2 from shifting in position in the first direction D1, the engagement portion 216 of the partition plate 2 elastically engages with the engagement hole 142 of the second side wall 14, thereby preventing the partition plate 2 from coming off upward, and further, the protrusion 218 of the partition plate 2 abuts against the side surface 156 of the restriction wall 15, thereby effectively preventing the engagement portion 216 of the partition plate 2 from accidentally coming off the engagement hole 142 of the second side wall 14. Therefore, even when the container 9 is subjected to vertical vibrations or when an impact is applied to the bottom surface of the container body 1, the partition plate 2 is effectively prevented from coming off from the container body 1.

[0116] As explained based on the third modified example, in the container 9 according to the second aspect of the present disclosure, in the first aspect, at the edge portion 214 of the partition plate 2, the engagement portion 216 and the protrusion portion 218 are positioned offset from each other in the first direction D1.

[0117] According to this embodiment, the engaging portion 216 and the protruding portion 218 can be compactly arranged at the edge portion 214 of the partition plate 2, and the distance between the engaging portion 216 and the protruding portion 218 in the second direction D2 can be set short. This shortens the distance between the restricting wall 15 and the second side wall 14, and as a result, it becomes easier to ensure the substantial inner dimension of the container body 1 (i.e., the dimension between the pair of restricting walls 15).

[0118] As explained based on the third variant, in the container 9 according to the third aspect of the present disclosure, in the first or second aspect, the engagement portion 216 of the partition plate 2 is positioned offset in the first direction D1 relative to the main portion 210 of the partition plate 2.

[0119] According to this embodiment, the engaging portion 216 can be compactly arranged at the edge portion 214 of the partition plate 2, which allows the distance between the restricting wall 15 and the second side wall 14 to be set short. As a result, it becomes easier to ensure the substantial inner dimensions of the container body 1 (i.e., the dimensions between the pair of restricting walls 15). [Explanation of symbols]
