DETAILED DESCRIPTION OF THE INVENTION

[0010] 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.

[0011] (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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] (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.

[0016] 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.

[0017] The configuration of the container body 1 will be described in more detail below.

[0018] (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.

[0019] (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.

[0020] 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.

[0021] (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.

[0022] (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.

[0023] (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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] (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. It is also possible to form the insertion groove 5 as a groove that is open only upward.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] (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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] (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.

[0044] 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.

[0045] The two engaging portions 8 have the following common structure.

[0046] The engagement portion 8 is provided extending from the bottom wall 11 of the container body 1. The engagement portion 8 includes a protruding piece-shaped support body 82 standing up 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.

[0047] 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.

[0048] (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.

[0049] The plurality of partition plates 2 have a common structure as described below.

[0050] 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).

[0051] 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.

[0052] The configuration of the partition plate 2 will be described in more detail below.

[0053] (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.

[0054] (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.

[0055] (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.

[0056] 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. The above-described shape of the partition plate main body 21 is merely an example, and the first surface 211 and the second surface 212 may not have shapes that are rotationally symmetrical to each other.

[0057] (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.

[0058] Both end edges 214 of the partition plate body 21 are inserted from above into the corresponding vertical grooves 4 to be locked, and each constitutes a locking portion 28 of the partition plate 2. The locking portions 28 on both sides of the partition plate 2 are flat plate-like portions that protrude from the upper part of the main portion 210 of the partition plate body 21 in directions away from each other in the second direction D2. The locking 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 by a vertical plane perpendicular to the second direction D2. In each of the locking portions 28 on both sides, the vertical length of the locking portion 28 is formed to be longer than the thickness of the locking portion 28.

[0059] (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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] (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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] FIG. 8A shows a cross section of a main part of a container 9 according to a fourth modified example. In this modified example, another portion 66 of the lower edge of the receiving groove 6 (i.e., a portion of the lower edge of the receiving groove 6 that is one step higher than the locking recess 67) is configured as an inclined surface 662. The inclined surface 662 is inclined so that the portion closer to the locking recess 67 is positioned lower in the first direction D1. In the example shown in FIG. 8A, the inclination angle of the inclined surface 662 is uniform; in other words, the inclined surface 662 is configured as a uniformly inclined flat surface, but this is not limiting. As long as the inclined surface 662 is inclined overall so that the portion closer to the locking recess 67 is positioned lower, the inclination angle may vary along the way. The inclined surface 662 may also be configured as a convex curved surface, a concave curved surface, or a combination of a convex curved surface and a concave curved surface.

[0077] According to the container 9 of the fourth modified example described above, the lower end of the locking portion 28 of the partition plate 2 is guided toward the locking recess 67 while sliding against the inclined surface 662 of the accommodating groove 6. In other words, the inclined surface 662 of the accommodating groove 6 can function as a guide surface that guides the lower end of the locking portion 28 of the partition plate 2 toward the locking recess 67.

[0078] FIG. 8B shows a cross section of a main portion of a container 9 according to a fifth modified example. In this modified example, another portion 66 of the lower edge of the receiving groove 6 is composed of an inclined surface 664 and a flat surface 665 that faces directly upward and extends in the first direction D1. The inclined surface 664 constitutes a portion of the other portion 66 that is closer to the locking recess 67. The inclined surface 664 is inclined so that the portion closer to the locking recess 67 is positioned lower in the first direction D1. In the example shown in FIG. 8B, the inclination angle of the inclined surface 664 is uniform, but this is not limiting. As long as the inclined surface 664 is inclined overall so that the portion closer to the locking recess 67 is positioned lower, the inclination angle may vary along the way. The inclined surface 664 may be composed of a convex curved surface, a concave curved surface, or a combination of a convex curved surface and a concave curved surface.

[0079] According to the container 9 of the fifth modified example described above, the lower end of the locking portion 28 of the partition plate 2 is guided toward the locking recess 67 while sliding against the inclined surface 664 of the accommodating groove 6. In other words, the inclined surface 664 of the accommodating groove 6 can function as a guide surface that guides the lower end of the locking portion 28 of the partition plate 2 toward the locking recess 67.

[0080] Furthermore, in the container 9 of the fifth modified example, at least one corner 285 of the locking portion 28 of the partition plate 2 is configured as a corner that is chamfered to have a rounded arc-shaped cross section. The chamfered corner 285 is a corner at the lower end of the locking portion 28, and is provided so as to come into sliding contact with the inclined surface 664 of the storage groove 6 when the lower end of the locking portion 28 is fitted into the locking recess 67. Therefore, the lower end of the locking portion 28 of the partition plate 2 is smoothly guided toward the locking recess 67 while the chamfered corner 285 comes into sliding contact with the inclined surface 664. In this modified example, of the multiple corners of the locking portion 28 of the partition plate 2, the corner 285 that is configured to come into sliding contact with the inclined surface 664 has a larger radius of curvature than the other corners.

[0081] FIG. 9A shows a cross section of a main part of a container 9 according to a sixth modified example. In this modified example, the first side surface 51 of the insertion groove 5 is not configured with a uniformly inclined inclined surface 55, but is configured with multiple inclined surfaces 511, 512 having different inclination angles. The multiple inclined surfaces 511, 512 are, for example, two inclined surfaces 511, 512 that are continuous in the first direction D1. Of the two inclined surfaces 511, 512, the inclination angle of the lower inclined surface 511 (i.e., the side closer to the opening 60) is set to be larger than the inclination angle of the upper inclined surface 512 (i.e., the side farther from the opening 60). One or more inclined surfaces having inclination angles different from those of the two inclined surfaces 511, 512 may be interposed between the two inclined surfaces 511, 512. The inclination angle of the one or more inclined surfaces here is preferably set to be smaller than the inclination angle of the inclined surface 511 and larger than the inclination angle of the inclined surface 512. Furthermore, a convex curved surface that smoothly connects the two inclined surfaces 511 and 512 may be interposed between the two inclined surfaces 511 and 512.

[0082] 9B shows a cross section of a main part of container 9 of a seventh modified example. In this modified example, first side surface 51 of insertion groove 5 is configured with convex curved surface 514 rather than with uniformly inclined inclined surface 55. The inclination of convex curved surface 514 gradually changes so that the angle of inclination increases toward the lower side (i.e., the side closer to opening 60). In this modified example, the radius of curvature of convex curved surface 514 is uniform, but the radius of curvature of convex curved surface 514 may change stepwise or continuously.

[0083] 9C shows a cross section of a main part of a container 9 according to an eighth modified example. In this modified example, the first side surface 51 of the insertion groove 5 is configured with a concave curved surface 516 rather than a uniformly inclined inclined surface 55. The inclination of the concave curved surface 516 gradually changes so that the angle of inclination becomes smaller toward the lower side (i.e., the side closer to the opening 60). In this modified example, the radius of curvature of the concave curved surface 516 is uniform, but the radius of curvature of the concave curved surface 516 may change in a stepwise or continuous manner.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 3. Summary As described above based on the embodiment and various modified examples, the container 9 according to the 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 and a plurality of side walls 12. The partition plate 2 is detachably attached to the container body 1 to divide the internal space of the container body 1. The plurality of side walls 12 include a pair of side walls 14 having vertical grooves 4 into which the edge portion 214 of the partition plate 2 is inserted from above. The vertical grooves 4 include an insertion groove 5 that opens upward and a storage groove 6 that extends downward from the insertion groove 5. The insertion groove 5 and the storage groove 6 are in communication with each other at positions where their central axes C5, C6 are offset from each other.

[0095] According to this embodiment, a step is created between the insertion groove 5 and the storage groove 6 below it, so even if the edge 214 of the partition plate 2 moves upward within the storage groove 6, it gets caught on the step and is prevented from slipping out upward. 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 the container body 1.

[0096] In the container 9 according to the second aspect of the present disclosure, in the first aspect, the storage groove 6 has a retaining portion 65 that forms a step 7 between it and the insertion groove 5. The storage groove 6 is provided wider than the insertion groove 5 via the step 7.

[0097] According to this embodiment, even if the edge portion 214 of the partition plate 2 moves upward within the storage groove 6, it will come into contact with the retaining portion 65 of the storage groove 6 and will be prevented from falling out upward. 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 out of the container body 1.

[0098] In the container 9 according to the third aspect of the present disclosure, in the second aspect, the lower edge of the storage groove 6 includes a locking recess 67 that is recessed downward relative to the other portion 66 of the lower edge. A retaining portion 65 is located above the locking recess 67.

[0099] According to this embodiment, the edge portion 214 of the partition plate 2 fits into the locking recess 67, thereby positioning the partition plate 2. Furthermore, even if the edge portion 214 of the partition plate 2 moves upward through the locking recess 67, it will come into contact with the anti-slip portion 65 located above it, thereby effectively preventing the partition plate 2 from coming off the container body 1.

[0100] In the container 9 according to the fourth aspect of the present disclosure, in the second or third aspect, the insertion groove 5 has an inclined surface 55 that guides the edge portion 214 of the partition plate 2 toward the storage groove 6. The inclined surface 55 is located above the retaining portion 65.

[0101] According to this embodiment, the edge portion 214 of the partition plate 2 can be smoothly guided into the storage groove 6 by sliding it against the inclined surface 55 of the insertion groove 5, and since the inclined surface 55 is located above the anti-slip portion 65, the width dimension of the vertical groove portion 4 is reduced.
