Since the connecting portion 3a extends toward the upper side S13 of the extension surface 1E, the connecting portion 3a can extend upward by a distance between both ends 3b in the vertical direction of the connecting portion 3. In the storage box 1 of FIG. 7, since the bending guide lines 3c are formed in the vicinity of both ends 3b in the vertical direction of the connecting portion 3a, the vicinity of both ends 3b in the vertical direction of the connecting portion 3a are easily bent. You can easily turn around.
The storage box 1 can be hung by exposing the hanging portion 3 to the outside of the storage box 1 and hooking the hanging portion 3 on a bar.

Although the storage box 1 in the illustrated example is a rectangular parallelepiped having six sides, it is not limited to a rectangular parallelepiped, but may be a cube, a triangular prism, or a column. In addition, the extension surface 1E has substantially the same area as the front side surface 1A, and two hooks 3 are formed on the upper and lower portions of the extension surface 1E, exposing the hooks 3 to the outside of the storage box 1. Opening 2 for front side 1A
May be formed near the upper side S1 and near the lower side S2. In the storage box 1 provided with the two hooks 3, the top surface 1
Not only can the storage box 1 be hung with the F ₁ and 1F ₂ up, but also the storage box 1 can be hung with the bottom surfaces 1G ₁ and 1G ₂ up.

In the hook portion 3, a second hook portion of the same shape and size may be connected via the upper side of the hook portion 3. The strength of the hook can be improved by overlapping and fixing the second hook to the hook 3.

As the material of the storage box 1, a cardboard or a thermoplastic synthetic resin sheet, or a laminate sheet of a cardboard and a thermoplastic synthetic resin sheet can be used. As the thermoplastic synthetic resin sheet, it is preferable to use transparent or translucent polypropylene or polyethylene having a light projecting property. Sticking and top surface _1F 1 of the front side 1A of the storage box 1 and site 1E ₁ of extended surface 1E, 1F ₂ How to fixation, the fixation of to what bottom _1G 1, 1G _2, adhesive or thermal fusion techniques Can be used.

The storage box 1 having a bent guide line 3c extending in the horizontal direction near both ends 3b in the vertical direction of the connecting portion 3a is suitable when the storage box 1 is formed of a synthetic resin sheet. Although the storage box 1 made of a synthetic resin sheet depends on the rigidity of the synthetic resin sheet, the connecting portion 3a is formed at its longitudinal ends 3b.
There are cases where it is difficult to bend in the vicinity. However, the bent guide line 3c is located near both ends 3b in the longitudinal direction of the connecting portion 3a.
Can solve such a problem. The folding guide line 3c may be a cut line slightly cut in the thickness direction of the sheet surface of the synthetic resin sheet or a perforation penetrating the sheet surface of the synthetic resin sheet.
