This is a stacked fitting portion 10B.

Next, stacking of the first containers 10 will be explained. First, when another first container 10 is stacked on top of the first container 10 in the same direction, as shown in FIG. A stacking state is reached in which the upper surfaces of the side walls 12 and 13 (that is, the upper surface of the upper end flange wall 14) are in contact with each other. In this stacked state, the lower end protrusion 20T of the first container 10 on the upper stage is received in the slide groove 24 of the first container 10 on the lower stage, and the stacked fitting part 10B of the first container 10 on the upper stage is The upper and lower first containers are received in the upper surface opening 10K of the first container 10 on the lower stage side, and the lower surface rib 20L of the first container 10 on the upper stage side is received in the upper surface opening 10K of the first container 10 on the lower stage side. 10 horizontal displacement can be suppressed.

Specifically, the leg portions 20 of the pair of first side walls 13 of the first container 10 on the upper stage are abutted against the upper surfaces of the pair of first side walls 13 of the first container 10 on the lower stage, and the first container 10 on the upper stage is opened. The container 10 may be placed in an inclined position, and the first container 10 on the upper stage side may be slid in the second horizontal direction H2. At this time, the lower end protrusion 20T of the leg portion 20 of the first container 10 on the upper stage is received in the slide groove 24 of the first container 10 on the lower stage, so that the sliding operation can be performed smoothly.

Furthermore, as shown in FIG. 1, the first container 10 is color-coded into two colors in the first horizontal direction H1, and the colors of the pair of first side walls 13 are different from each other. Note that colors are omitted in FIGS. 2 to 14, 17, 18, 21, and 22.

Next, the second container 40 will be explained. The second container 40 will be described with its lateral direction aligned with the first horizontal direction H1 and its longitudinal direction aligned with the second horizontal direction H2. As shown in FIGS. 11 and 12, the side walls 42 and 43 of the second container 40 include a pair of first side walls 43 that stand up from the long sides, and a pair of first side walls 43 that stand up from the short sides of the bottom wall 41. 2 side walls 42. Like the first container 10, the second container 40 has a pair of legs 50 and a vertical groove 52 on each side wall 42, 43, and can be stacked in a stacking state or a nesting state. Further, a slide groove 54 (corresponding to a "slide rail" in the claims) is also formed on the upper surface (namely, the upper end flange wall 44) of the pair of first side walls 43 of the second container 40. Further, one of the second side walls 42 of the pair of second side walls 42 of the second container 40 (the second side wall 42 on the near side in FIG. 1; hereinafter referred to as "front second side wall 42A" as appropriate) includes: Similarly to the front second side wall 12A of the first container 10, a card holder attachment portion 42T and a card holder support protrusion 42S are formed.

As described above, the second container 40 is smaller than the first container 10, but its vertical and horizontal lengths are as follows. That is, the length of the second container 40 in the second horizontal direction H2 (longitudinal direction) is the same as the length of the first container 10 in the second horizontal direction H2 (width direction); The length in the first horizontal direction H1 (short direction) is 2/3 times the length in the first horizontal direction H1 (longitudinal direction) of the first container 10 (i.e., the length in the first horizontal direction H1 (longitudinal direction) of the first container 10 is The length of the first horizontal direction H1 is 3/2 times the length of the second container 40 in the first horizontal direction H1). As a result, the planar shape of the second container group 60, which has three second containers 40 arranged in one row in the first horizontal direction H1, and the planar shape in which two first containers 10 are arranged in the first horizontal direction H1. are almost the same.

Here, as shown in FIG. 3, the first container 10 has a first receiving groove extending in the second horizontal direction H2 (short side direction) in the stacked fitting part 10B (lower surface of the first container 10). 35 and a second receiving groove 36 extending in the first horizontal direction H1 (longitudinal direction). The first receiving groove 35 and the second receiving groove 36 are formed by reducing the amount of protrusion of the rib 11L formed on the bottom wall 11 from the flat plate 11A. Specifically, on the back surface of the flat plate 11A of the bottom wall 11, there are three rectangular lattice rib groups 11L1 with a relatively large protrusion in the first horizontal direction H1 (longitudinal direction) and three in the second horizontal direction H2 (short). A total of six grooves (two in the hand direction) are arranged, and the first receiving groove 35 and the second receiving groove 36 are arranged between them.

As shown in the figure, the second receiving groove 36 is disposed at the center of the second horizontal direction H2 (lateral direction), while the first receiving groove 35 is arranged so that the first container 10 is Two pieces are placed at positions that divide it into three equal parts (in the longitudinal direction). The width of the first receiving groove 35 is large enough to receive the upper ends (i.e., the upper end flange walls 44) of the pair of first side walls 43 of the two second containers 40 arranged side by side.

As shown in FIGS. 13 and 14, the legs 50 and vertical grooves 52 of the pair of first side walls 43 of the second container 40 are the same as the legs 20 and the vertical grooves of the pair of first side walls 13 of the first container 10. It is arranged at the same position as the groove 22 (see FIGS. 7 and 8). As a result, the first side wall 13 of the first container 10 is stacked on the first side wall 43 of the second container 40 with the front second side walls 12A and 42A of both the first container 10 and the second container 40 facing the same direction. While the leg portion 20 of the first side wall 13 of the first container 10 contacts the upper surface (upper end flange wall 44) of the first side wall 43 of the second container 40, one of the front second side walls 12A, 42A When the first side wall 13 of the first container 10 is stacked on the first side wall 43 of the second container 40 with the front second side wall facing oppositely, the legs 20 of the first side wall 13 of the first container 10 2 overlaps the vertical groove 52 of the first side wall 43 of the container 40.

Further, the distances between the legs 50 and the vertical grooves 52 of the pair of second side walls 42 of the second container 40 from the first side wall 43 and the distances between the legs 50 and between the vertical grooves 52 are different from each other in the first container 10. The distances between the legs 20 and the vertical grooves 22 of the pair of second side walls 12 from the first side wall 13 and the distances between the legs 20 and between the vertical grooves 22 are different. Furthermore, when arranging two first containers 10 in the first horizontal direction H1 on the second container group 60 of three in one row (see FIG. 1), which one of the first containers 10 and the second containers 40 are placed? Regardless of the orientation, all the legs 20 of the second side wall 12 of the first container 10 abut at least one part on the upper surface of the second side wall 42 of the second container 40 (see FIGS. 15 and 16). . In the example shown in FIG. 15, for example, a part of the left leg 20 of the rear second side wall 12B of the left first container 10 is placed on the vertical groove 52 of the second container 40, and the rest is placed on the vertical groove 52 of the second container 40. It is in contact with the upper surface of the second side wall 42. In this way, a part of the leg part 20 of the first container 10 may be disposed on the vertical groove 52 of the second container 40, or all of the leg parts 20 of the first container 10 may be arranged as a whole. However, the structure may be such that it contacts the upper surface of the second side wall 42 (that is, is not arranged on the vertical groove 52).

Further, as shown in FIG. 1, like the first container 10, the second container 40 is also color-coded into two colors in the first horizontal direction H1, and the color of the pair of first side walls 43 is different. . Furthermore, the color of one of the pair of first side walls 43 of the second container 40 is different from that of the first side wall 13 of the first container 10 in which the legs 20, 50 and the longitudinal grooves 22, 52 are arranged in the same way. The color is the same as that of Hereinafter, the color of the first side walls 13 and 43 of the same color will be referred to as a "specific color."
