The container 1 is a resin molded product.

[0013] 2-1. Container body The container body 2 has a rectangular box shape with an open top. As shown in Figures 3 to 5, in this embodiment, the container body 2 has a substantially rectangular box shape. In the following, each configuration will be described with the longitudinal direction of the container body 2 in a plan view as the left-right direction, the short side direction of the container body 2 in a plan view as the front-rear direction, and the direction perpendicular to the left-right direction and the front-rear direction as the up-down direction.

[0014] 2 to 6, the container body 2 includes a bottom wall 20 that is generally rectangular in plan view, two side walls 21 and 22 that are erected on two short sides (i.e., left and right end sides) of the bottom wall 20, and two side walls 23 and 24 that are erected on two long sides (i.e., front and rear end sides) of the bottom wall 20. The container body 2 further includes connecting side walls 25 that are erected on four corner sides of the bottom wall 20 and have an arc-like shape in plan view, connecting two adjacent side walls out of the four side walls 21, 22, 23, and 24.

[0015] 3 and 6, the bottom wall 20 is a generally rectangular flat plate with the longitudinal direction being the left-right direction and the transverse direction being the front-rear direction. A bulge 200 that protrudes upward and opens downward is formed in a portion of the bottom wall 20 in the left-right direction. The bulge 200 is provided over the entire length of the bottom wall 20 in the front-rear direction. The front-rear direction ends of the bulge 200 are connected to the side walls 23, 24.

[0016] The bulging portion 200 has a generally U-shaped cross section perpendicular to the longitudinal direction. A plurality of connecting ribs 201 extending in the left-right direction are provided inside the bulging portion 200 at intervals in the front-rear direction. Each of the connecting ribs 201 is integrally provided with a pair of inner side surfaces and an inner bottom surface (surfaces facing downward) that face opposite each other in the left-right direction of the bulging portion 200.

[0017] In this embodiment, two bulging portions 200 are provided at a distance in the left-right direction on the bottom wall 20. The left end edge of the bottom wall 20, the left bulging portion 200, the right bulging portion 200, and the right end edge of the bottom wall 20 are positioned at approximately equal intervals.

[0018] By providing two bulging portions 200 that protrude upward in this manner on the bottom wall 20, when the bag is attached to the container 1, the two bulging portions 200 function as simple partitions, making it easy to position the contents inside the bag.

[0019] As shown in FIGS. 2 and 3, the left and right side walls 21, 22 face each other in the left-right direction and are inclined outward in the left-right direction relative to a vertical plane so that the width (inner dimension in the left-right direction) increases toward the upper portion.

[0020] The front and rear side walls 23, 24 face each other in the front-rear direction and are inclined outward in the front-rear direction relative to a vertical plane so that the width (inner dimension in the front-rear direction) increases toward the upper portion. Each of the four side walls 21, 22, 23, 24 is flat.

[0021] The connecting side walls 25 are interposed between two adjacent side walls among the four side walls 21, 22, 23, and 24. The container body 2 has four connecting side walls 25. Each of the four connecting side walls 25 is inclined so that the upper portion is positioned more outward.

[0066] Therefore, the distance between the first support leg 60 and the second support leg 61 is wider than the distance between the third support leg 62 and the fourth support leg 63. The distance between the first support leg 60 and the second support leg 61 is the same as the distance between the third groove portion 42 and the fourth groove portion 43. The distance between the third support leg 62 and the fourth support leg 63 is the same as the distance between the first groove portion 40 and the second groove portion 41.

[0067] As shown in FIGS. 2 and 7, the first support leg 60 and the fourth support leg 63 have a common structure, and the second support leg 61 and the third support leg 62 have a common structure.

[0068] The first support leg 60 and the fourth support leg 63 each have a hollow structure with an open bottom. The first support leg 60 and the fourth support leg 63 each allow the locking portions 441 and 471 of the recesses 44 and 47 to be inserted therein.

[0069] 2 and 5, the second support leg 61 is located from the middle to the lower end in the vertical direction of the side wall 21. The upper end of the second support leg 61 is continuous with the intermediate flange 501 at the lower end of the first side rib 50.

[0070] 7, the third support leg 62 is located from the middle to the lower end in the vertical direction of the side wall 22. The upper end of the third support leg 62 is continuous with the intermediate flange 511 at the lower end of the second side rib 51.

[0071] 5, the second support leg 61 is composed of two vertical ribs 610 extending in the up-down direction and spaced apart in the left-right direction, one horizontal rib 611 connecting the lower ends of the two vertical ribs 610, and a horizontal rib 612 connecting the vertical middle parts of the two vertical ribs 610. The upper ends of the two vertical ribs 610 are continuous with the intermediate flange 501 at the lower end of the first side rib 50. As shown in FIGS. 2 and 7, the third support leg 62 has the same structure as the second support leg 61.

[0072] The third support leg 62 is composed of two vertical ribs 620, two vertical ribs 620, one horizontal rib 621 connecting the lower ends of the two vertical ribs 620, and a horizontal rib 622 connecting the middle parts in the up-down direction of the two vertical ribs 620. The upper ends of the two vertical ribs 620 are continuous with the intermediate flanges 511 at the lower ends of the second side surface ribs 51.

[0073] 2-6.Other The container 1 of this embodiment shown in Figure 2 has a length in the left-right direction (i.e., maximum outer dimension) of, for example, 600 mm, a length in the front-to-back direction (i.e., maximum outer dimension) of, for example, 400 mm, and a length in the up-to-down direction (i.e., maximum outer dimension) of, for example, 340 mm.

[0074] 3, in the container 1 of this embodiment, the length L3 in the left-right direction from the leading end surface (left end surface) of the first convex portion 300 to the leading end surface (right end surface) of the second convex portion 301 is the length in the left-right direction (maximum outer dimension).The length in the front-rear direction from the leading end surface (front end surface) of the third flange portion 34 to the leading end surface (rear end surface) of the fourth flange portion 35 is the length in the front-rear direction (maximum outer dimension).The length from the upper surface of the flange 3 to the lower surface of the bottom wall 20 is the length in the up-down direction (maximum outer dimension).

[0075] 3. Container placement method Next, a method for arranging the above-mentioned container 1 will be described.

[0076] First, an arrangement method in which two containers 1 are arranged side by side in the left-right direction will be described.

[0077] As shown in Figures 1 and 8, when two containers 1 of this embodiment are arranged side by side in the left-right direction, the flange 3A of one (left) container 1A and the flange 3B of the other (right) container 1B can be arranged so that they overlap when viewed from the front (in direction D1).

[0078] 9, the second convex portion 301 of the second flange portion 33 of the left container 1A fits into the first concave portion 310 of the first flange portion 32 of the right container 1B. Then, the first convex portion 300 of the first flange portion 32 of the right container 1B fits into the second concave portion 311 of the second flange portion 33 of the left container 1A. At this time, the tip surface (right surface) of the portion between the convex portion 301 and the concave portion 311 of the second flange portion 33 of the left container 1A comes into contact with the tip surface (left surface) of the portion between the convex portion 300 and the concave portion 310 of the first flange portion 32 of the right container 1B.

[0079] As a result, the second flange portion 33 of the container 1A and the first flange portion 32 of the container 1B overlap when viewed from the front. Therefore, as shown in Fig. 4, the total left-right length L4 of the containers 1A and 1B is shorter than the sum of the left-right lengths L3 of the containers 1A and 1B.

[0080] Next, a method of arranging two containers 1 one above the other in the vertical direction will be described.

[0081] The containers 1 of this embodiment can be arranged two above and two below in a stacked state as shown in FIG. 10A or in a nested state as shown in FIG. 10B.

[0082] In the stacked state shown in FIG. 10A, the lower container 1C and the upper container 1D are oriented in the same direction as the container 1 shown in FIG.

[0083] In the stacked state, the support legs 60, 61 of the upper container 1D rest one-to-one on the support surfaces 440, 450 of the recesses 44, 45 of the lower container 1C. Also, the support legs 62, 63 of the upper container 1D rest one-to-one on the support surfaces 460, 470 of the recesses 46, 47 of the lower container 1C. As a result, the two containers 1C, 1D are stacked vertically, with only the lower end of the upper container 1D fitted inside the lower container 1C.

[0084] In the nested state shown in Figure 10B, the lower container 1C is oriented in the same direction as the container 1 shown in Figure 2, and the upper container 1D is the container 1 shown in Figures 2 and 3 rotated 180 degrees around a vertical axis passing through the center C1 of the container body 2.

[0085] In the nested state shown in Figure 10B, the support legs 63, 62 of the upper container 1D are inserted one-to-one into the grooves 40, 41 of the lower container 1C. Furthermore, the support legs 61, 60 of the upper container 1D are inserted one-to-one into the grooves 42, 43 of the lower container 1C. The intermediate flanges 501, 511 of the side ribs 50, 51 of the upper container 1D rest on the upper surfaces of the flanges 32, 33 of the lower container 1C. As a result, the two containers 1C, 1D are stacked vertically, with the lower half of the upper container 1D fitted inside the lower container 1C.

[0086] 4. Effects 1, 8, and 9, when two containers 1 of this embodiment are arranged side by side in the left-right direction, the first convex portion 300 of the flange 3A of one container 1A can be accommodated in the second concave portion 311 of the flange 3B of the other container 1B. At this time, the second convex portion 301 of the flange 3B of the other container 1B can be accommodated in the first concave portion 310 of the flange 3A of one container 1A.

[0087] As a result, in the container 1 of this embodiment, the flanges 3A, 3B of the two containers 1A, 1B can be arranged in an overlapping state when viewed from the front, allowing for a compact arrangement when the two containers are arranged side by side. For example, if the outer dimension in the left-right direction of the containers 1A, 1B is 600 mm, the outer dimension in the left-right direction when the containers 1A, 1B are arranged side by side can be 1166 mm.

[0088] Therefore, for example, even if the dimensions of a shelf placed on a delivery vehicle are slightly shorter than the combined length of the outer dimensions of the two containers 1A, 1B, the two containers 1A, 1B can be placed side by side on this shelf.

[0089] 3, the tip surfaces of the convex portions 300, 301 of the container 1 of this embodiment have curved surfaces on the outer side in the front-to-rear direction, and the wall surfaces 360, 361 located on the outer side in the front-to-rear direction of the concave portions 310, 311 are inclined surfaces. Therefore, when two containers 1 of this embodiment are arranged side by side in the left-to-right direction as shown in FIG. 8, the right container 1B can be easily pulled forward relative to the left container 1A, and the left container 1A can be easily pulled backward relative to the right container 1B.

[0090] Furthermore, in the container 1 of this embodiment, the tip surfaces of the convex portions 300, 301 are smoothly connected via the curved surface portions to the tip surfaces of the third flange portion 34 and the fourth flange portion 35. Therefore, in the container 1 of this embodiment, when the container 1 is transported on a roller conveyor or the like, even if a corner portion of the flange 3 of the container 1 collides with a guide provided along the roller conveyor, it is easy to prevent the convex portions 300, 301 from getting caught or being damaged.

[0091] 9, the two containers 1A, 1B can be prevented from moving upward relative to each other because the convex portions 300, 301 of one container 1A, 1B are positioned above the flange portions 32, 33 of the other container 1B, 1A. Therefore, the container 1 of this embodiment can easily prevent the containers 1A, 1B from rattling during transportation, for example, by a delivery vehicle.

[0092] 3, in the container 1 of this embodiment, the tip surfaces of the convex portions 300, 301 are smoothly continuous with the tip surfaces of the flange portions 34, 35. Therefore, in the container 1 of this embodiment, after two containers are arranged side by side in the left-right direction, when one container 1 is moved back and forth relative to the other container 1, it is easy to prevent the convex portions 300, 301 from getting caught or being damaged.

[0093] Furthermore, in the container 1 of this embodiment, the flange 3 protrudes from the upper end of the container body 2 over the entire periphery, and therefore the strength and rigidity of the container 1 against twisting can be improved.

[0094] Furthermore, in the container 1 of this embodiment, as shown in Figures 2 and 5, the convex portions 300, 301 are composed of horizontal ribs and multiple vertical ribs protruding downward from the horizontal ribs, and the multiple vertical ribs include corner vertical ribs located at the corners of the flange 3, making it easy to ensure the strength of the convex portions 300, 301 at the corners of the flange 3.

[0095] Furthermore, in the container 1 of this embodiment, the portions of the flange portions 32, 33 below the recesses 310, 311 are made up of a plurality of vertical flanges and a plurality of horizontal flanges connected in a lattice pattern, thereby improving the rigidity of the short portions of the flange portions 32, 33 in the vertical direction (portions where the recesses 310, 311 are located).

[0096] Furthermore, in the container 1 of this embodiment, of the two support legs 6 provided on each of the left and right side walls 21 and 22, one support leg 60, 63 is provided only on the lower end of the left and right side walls 21, 22. Therefore, in the container 1 of this embodiment, it is possible to widely provide on the outer surfaces of the left and right side walls 21, 22 flat attachment portions 26 to which stickers or the like bearing information about the items to be stored in the container 1 can be attached.

[0097] (Variation) Next, we will explain modified examples of the above-mentioned container 1. The modified examples explained below can be combined as appropriate.

[0098] The containers 1 are not limited to the structure shown in FIG. 2, as long as the flanges 3 of both containers 1 overlap when viewed from the front when two containers 1 are arranged side by side.

[0099] For example, as shown in variant example 1 in Figure 11, the container 1 may have a recess 31 formed in the first flange portion 32 over the entire length in the front-to-rear direction, and a protrusion 30 formed in the second flange portion 33 over the entire length in the front-to-rear direction.

[0100] In this case, when two containers 1 are arranged side by side, the convex portion 30 of the second flange portion 33 of one (left) container 1 fits into the concave portion 31 of the first flange portion 32 of the other (right) container 1, and the flanges 3 of the two containers 1 overlap when viewed from the front. Therefore, even with the containers 1 of Modification 1, two containers can be arranged compactly when arranged side by side.

[0101] Furthermore, the container 1 may have recesses 31 provided at the front and rear ends of the first flange portion 32, and protrusions 30 provided at the front and rear ends of the second flange portion 33, respectively.

[0102] In this case, when two containers 1 are arranged side by side, the two convex portions 30 of the second flange portion 33 of one (left) container 1 fit into the two concave portions 31 of the first flange portion 32 of the other (right) container 1, respectively, and the flanges 3 of the two containers 1 overlap when viewed from the front. Therefore, even with this container 1, two containers can be arranged compactly when arranged side by side.

[0103] Furthermore, the positions of the convex portions 300, 301 and the concave portions 310, 311 in the front-rear direction of the flange portions 32, 33 of the container 1 are not limited to the positions shown in Fig. 2 etc. The positions of the first convex portion 300 and the first concave portion 310 in the first flange portion 32 may correspond to the positions of the second concave portion 311 and the second convex portion 301 in the second flange portion 33. The convex portions 300, 301 and the concave portions 310, 311 may be located in portions other than the front and rear end portions of the flange portions 32, 33, for example.

[0104] Furthermore, the vertical positions of the first convex portion 300 and the first concave portion 310 in the first flange portion 32 may correspond to the vertical positions of the second concave portion 311 and the second convex portion 301 in the second flange portion 33. For example, the convex portions 300, 301 and the concave portions 310, 311 may be located at the bottom of the flange portions 32, 33, or may be located over the entire flange portions 32, 33 in the vertical direction.

[0105] Furthermore, each of the recesses 310, 311 does not have to penetrate the side walls 21, 22, 25 and the flange portions 32, 33, 36 in the horizontal direction (left and right direction, etc.), and may be open in only one horizontal direction. Furthermore, each of the recesses 310, 311 does not have to open upward, and the upper surface may be closed by a part of the flange 3.

[0106] Furthermore, the outer shape of the flange 3 of the container 1 does not have to be point symmetric.

[0107] Furthermore, the container 1 may have support legs 60 and 61 that share a common structure, as in Modification 2 shown in Fig. 12. In Modification 2, the first support leg 60 is configured with a plurality of vertical ribs and a plurality of horizontal ribs, similar to the second support leg 61. Note that the support legs 62 and 63 may also have a common structure.

[0108] 2, 7, etc., the support legs 60, 63 of the container 1 may be formed in a square shape when viewed from the left to right. In this case, too, the outer surfaces of the left and right side walls 21, 22 can be provided with large flat mounting portions 26 to which seals or the like can be attached.

[0109] 13, the container 1 may have one support leg 6 provided on each of a pair of opposing side walls 21, 22 of the container body 2 and one support leg 6 provided on each of another pair of opposing side walls 23, 24. In the container 1 of the third modification, one groove portion 4 is provided on each of the side walls 21, 22, 23, 24.

[0110] The support legs 6 are made up of a total of four support legs: a support leg 6 protruding from the rear of the left side wall 21 (i.e., the second support leg 61), a support leg 64 protruding from the left portion of the front side wall 23, a support leg 6 protruding from the front portion of the right side wall 22 (i.e., the third support leg 62 (see FIG. 7)), and a support leg 6 (not shown) protruding from the right portion of the rear side wall 24. The front support leg 64 and the rear support leg 6 are each formed in the same shape as the support legs 61 and 62.

[0111] A side rib 522 having a structure similar to that of the side rib 50 is provided on the left side portion of the front side wall 23. The side rib 522 is composed of one vertical rib 523 and one intermediate flange 524. The upper end of the support leg 64 is connected to the intermediate flange 524 at the lower end of the side rib 522.

[0112] The container 1 further includes a corner intermediate flange 54 connecting the intermediate flange 501 of the side rib 50 of the left side wall 21 to the intermediate flange 524 of the side rib 522 of the front side wall 23. The corner intermediate flange 54 protrudes from the left front connecting side wall 25.

[0113] A side rib having a structure similar to that of the side rib 522 is also provided on the rear side wall 24, and the upper ends of the support legs 6 are connected to the intermediate flanges at the lower ends of these side ribs. The intermediate flange 511 (see FIG. 7) of the side rib 51 on the right side wall 22 and the intermediate flange of the side rib on the rear side wall 24 are connected via a corner intermediate flange protruding from the right rear connecting side wall 25.

[0114] On the outer surface of each of the side walls 21, 22, 23, and 24, a flat mounting portion 26 is provided at the lower end of the end opposite the side on which the support leg 6 is provided, to which a sticker or the like bearing information about the items to be stored in the container 1 can be attached.

[0115] The container 1 further includes a recess 48 provided in the upper end of the front side wall 23 and the third flange portion 34, and a recess 49 provided in the upper end of the rear side wall 24 and the fourth flange portion 35. The recesses 48, 49 have the same structure as the recesses 45, 46. The recess 48 is located adjacent to the right side of the front groove portion 4, and the recess 49 is located adjacent to the right side of the rear groove portion 4. The front support leg 64 is located directly below the recess 48, and the rear support leg 6 is located directly below the recess 49.

[0116] The arrangement of the support legs 6 and the groove portions 4 on each side wall 21, 22, 23, 24 is set so that when two containers 1 are nested one above the other with their orientations rotated 180 degrees in a plan view (see Figure 10), the support legs 6 of the upper container 1 fit into the groove portions 4 of the lower container 1.

[0117] In the containers 1 of the third modified example described above, when two containers are arranged side by side in the left-right direction, the first convex portion 300 of the flange 3 of one container 1 can be accommodated in the second concave portion 311 of the flange 3 of the other container 1 (see FIG. 1). In this case, the support legs 6 (specifically, the support legs 61, 62) of the two containers 1 do not interfere with each other and do not interfere with the arrangement.

[0118] Furthermore, the arrangement of the convex portions 30 and concave portions 31 on the flange 3 of the container 1 is not limited to the arrangement shown in Fig. 2, and may be provided, for example, on the third flange portion 34 and the fourth flange portion 35. In this case, when two containers 1 are arranged side by side in the front-to-rear direction, they can be arranged compactly in the front-to-rear direction.

[0119] Furthermore, the container body 2 of the container 1 may be a rectangular box with an open top, and the shape in plan view is not limited to a rectangle, but may be another rectangular shape such as a trapezoid or a parallelogram.

[0120] For example, when the container body 2 is trapezoidal in plan view, the flange 3 also has a trapezoidal outer shape in plan view. In this case, for example, one of the first flange portion 32 and the second flange portion 33 is provided so as to be inclined with respect to the front-to-rear direction. The flange portions 32, 33 do not necessarily need to be provided with the convex portions 30 and the concave portions 31.

[0121] Furthermore, when the container body 2 has a parallelogram shape in plan view, the flange 3 also has a parallelogram shape in plan view. In this case, for example, both the first flange portion 32 and the second flange portion 33 are provided so as to be inclined with respect to the front-rear direction and parallel to each other. The flange portions 32, 33 do not necessarily have to have the protrusions 30 and the recesses 31.

[0122] Even if the outer shape of the flange 3 of the container 1 in a plan view is trapezoidal or parallelogram-shaped, when two containers 1 are placed side by side in the left-right direction, the flanges 3 of the two containers 1 overlap when viewed from the front, allowing for compact placement in the horizontal direction.

[0123] In addition, when the outer shape of the flange 3 of the container 1 in a planar view is trapezoidal or parallelogrammatic, the distance L1 from the outer surface of one end (one end in the longitudinal direction) of the first flange portion 32 to the center C1 of the container body 2 of the container 1 is longer than the distance L2 from the outer surface of the other end (other end in the longitudinal direction) of the first flange portion 32 to the center C1 of the container body 2.

[0124] In this embodiment, the container 1 is molded in one color, but may be molded in two colors. In the case of two-color molding, the boundary line between the two colors of resin may be located on the short side walls 21 and 22 of the container 1, or on the long side walls 23 and 24 of the container 1.

[0125] Furthermore, in this embodiment, the flange 3 has a hollow structure made up of a plurality of vertical ribs and a plurality of horizontal ribs, but is not limited to this and may have a solid structure.

[0126] (summary) As in the embodiment and its modified example described above, the container 1 of the first aspect has the following configuration.

[0127] That is, the container 1 of the first embodiment comprises a rectangular box-shaped container body 2 with an open top, and a flange 3 protruding outward from the upper part of the container body 2. The flange 3 is provided so that when two containers 1 are arranged side by side in one direction, the flange 3A of one container 1A and the flange 3B of the other container 1B overlap when viewed in a direction D1 that is perpendicular to the one direction and the up-down direction.

[0128] In the first embodiment of the container 1 having the above configuration, when two containers 1 are arranged side by side in one direction, the flange 3A of one container 1A and the flange 3B of the other container 1B overlap when viewed in a direction D1 perpendicular to the one direction and the up-down direction. Therefore, when two containers 1 of the first embodiment are arranged side by side, they can be arranged compactly.

[0129] As in the above-described embodiment and its modified example 1-3, the container 1 of the second aspect additionally comprises the following configuration in addition to the configuration of the container 1 of the first aspect.

[0130] That is, in the container 1 of the second embodiment, the flange 3 includes a convex portion 30 that protrudes outward and a concave portion 31 that is recessed inward. The convex portion 30 and the concave portion 31 are configured so that when two containers 1 are arranged side by side in the one direction, the convex portion 30A of the flange 3A of one container 1A fits into the concave portion 31B of the flange 3B of the other container 1B.

[0131] In the containers 1 of the second embodiment having the above configuration, when two containers 1 are arranged side by side in one direction, the convex portion 30A of the flange 3A of one container 1A fits into the concave portion 31B of the flange 3B of the other container 1B. Therefore, when two containers 1 of the second embodiment are arranged side by side, the movement of one container 1A, 1B in direction D1 perpendicular to the one direction and the up-down direction can be suppressed by the other container 1B, 1A.

[0132] Furthermore, as in the above-described embodiment and its modified example 1-3, the container 1 of the third aspect additionally comprises the following configuration in addition to the configuration of the container 1 of the second aspect.

[0133] That is, in the container 1 of the third embodiment, the container body 2 includes a first side wall (side wall 21) and a second side wall (side wall 22) that face each other. The flange 3 has a first flange portion 32 protruding from the first side wall and a second flange portion 33 protruding from the second side wall. The convex portion 30 includes a first convex portion 300 provided on the first flange portion 32 and a second convex portion 301 provided on the second flange portion 33. The concave portion 31 includes a first concave portion 310 provided on the first flange portion 32 and a second concave portion 311 provided on the second flange portion 33. The first convex portion 300 and the second concave portion 311 are provided in line-symmetric positions, and the second convex portion 301 and the first concave portion 310 are provided in line-symmetric positions.

[0134] With the above configuration, when two containers 1 of the third embodiment are arranged side by side, the positions of the two containers 1 can be aligned in the direction D1 perpendicular to the one direction and the up-down direction. Therefore, when two containers 1 of the third embodiment are arranged side by side, the outer dimensions in the perpendicular direction D1 can be prevented from becoming larger than the outer dimensions of one container 1 in the same direction D1.

[0135] As in the above-described embodiment and its modified example 1-3, the container 1 of the fourth aspect additionally comprises the following configuration in addition to the configuration of the container 1 of the third aspect.

[0136] That is, in the container 1 of the fourth embodiment, the first convex portion 300 is located at one end of the first flange portion 32, and the first concave portion 310 is located at the other end of the first flange portion 32. The second concave portion 311 is located at one end of the second flange portion 33, and the second convex portion 301 is located at the other end of the second flange portion 33.

[0137] By having the above configuration, in the fourth embodiment of the container 1, even if deformation such as bulging occurs in the first side wall and second side wall (side walls 21, 22) of the container body 2, the positional relationship between the convex portions 300, 301 and the concave portions 310, 311 is unlikely to change, making it easy to arrange two of them side by side in a compact manner.

[0138] Furthermore, like the embodiment and its modified example 1-3 described above, the container 1 of the fifth aspect additionally comprises the following configuration in addition to the configuration of the container 1 of the third or fourth aspect.

[0139] That is, in the container 1 of the fifth embodiment, the outer shape of the flange 3 is provided in point symmetry.

[0140] With the above configuration, in the container 1 of the fifth embodiment, even when two containers 1 are arranged side by side, one rotated 180° around a vertical axis passing through the center C1 of the container body 2 and the other not rotated, the flanges 3 of the two containers 1 can be overlapped, making it easy to arrange them compactly. In this way, in the container 1 of the fifth embodiment, since the rotated and non-rotated containers 1 can be arranged side by side, there are fewer restrictions on the arrangement orientation, making it easy to use.

[0141] Furthermore, as in the above-described third modification, the container 1 of the sixth embodiment additionally comprises the following configuration in addition to the configuration of the container 1 of the second embodiment.

[0142] That is, the container 1 of the sixth embodiment further includes support legs 6 protruding outward from the container body 2. The container body 2 includes a pair of side walls (side walls 21, 22) facing each other and another pair of side walls (side walls 23, 24) facing each other. One support leg 6 is provided on each of the pair of side walls (side walls 21, 22) and one support leg 6 is provided on each of the other pair of side walls (side walls 23, 24).
