As shown in FIG. 7 , the storage container 60 can be displayed by hooking the hook portion 100 on the counterpart member 2 . The mating member 2 is, for example, a metallic mesh member. It should be noted that the mating member 2 may be any member as long as the portion on which the hook portion 100 is hooked is shorter than at least the length of the lower edge of the first piece 112 in the front-rear direction.

The hook portion 100 bends each hook 110 rearward along the folding lines 116a and 116b with respect to the extension pieces 68a and 68b. Thereby, in the front-rear direction, the gap between the second piece 114 and the inner back plate 68 is wider than the counterpart member 2, and the counterpart member 2 is arranged between the second piece 114 and the inner back plate 68. , the storage container 60 can be hooked to the mating member 2 . According to this configuration, the hook portion 100 can be easily formed.

In the hook 110, a force is generated at the folding lines 116a and 116b to restore the extension pieces 68a and 68b on the same plane. As a result, the mating member 2 is sandwiched between the hook 110 and the inner back plate 68 . As a result, it is possible to prevent the storage container 60 from wobbling with respect to the counterpart member 2 .

Each hook 110 is constructed by stacking two flat plates. Each hook 110 is connected to a portion of the inner back plate 68 where the two extension pieces 68a and 68b are overlapped. As a result, deformation of the hook 110 and the extension pieces 68 a and 68 b around the hook 110 due to the weight of the storage container 60 can be suppressed.

In the storage container 60 , the extension pieces 82 and 86 of the inner plates 62 and 66 are connected to the extension piece 68 a via a folding line and arranged above the lower edge 113 of the hook 110 . According to this configuration, deformation of the inner back plate 68 can be suppressed.

As shown in FIG. 8, the first piece 112 of the hook 110 is inclined with respect to the mating member 2 (that is, in the left-right direction). Since the lower edge 113 of the first piece 112 is formed in a straight line, a large contact area between the first piece 112 and the mating member 2 can be ensured. As a result, concentration of stress applied to the first piece 112 can be suppressed and dispersed.

Folding lines 116a and 116b between the hook 110 and the inner back plate 68 are inclined downward from the upper end toward the first piece 112 side, ie, the first portions 112a and 112b. As a result, as shown in FIG. 9, the first piece 112 inclines downward as it goes rearward. Thereby, the second piece 114 inclines forward as it goes downward. According to this configuration, the second piece 114 spreads rearward away from the extension piece 68 a of the inner back plate 68 , thereby preventing the hook 110 from coming off the mating member 2 . In addition, for example, the angle θ in the drawing may be 70 degrees.

As shown in FIG. 10, when the folding line 206 between the hook 210 and the inner back plate 68 is parallel in the vertical direction, the first piece 202 is arranged in parallel in the front-rear direction, and the second piece 204 is arranged in the vertical direction. placed parallel to the As a result, compared to the hook 110 of this embodiment, the second piece 204 spreads rearward away from the extension piece 68a, making it easier for the hook 110 to come off the mating member 2 . The hook 110 of this embodiment spreads rearward away from the inner back plate 68 to avoid the hook 110 coming off the mating member 2 .
