があった。Each of the conventional storage boxes (A) and (B) is a box which is manually assembled, and includes a side plate, a wife plate,
Since it is necessary to assemble the decks and the like individually,
There was a problem that workability was poor. Furthermore, once the box has been assembled, it cannot be folded flat as it is in the assembled state, and when not in use, it can be stored in the assembled state, or the entire box can be disassembled and stored in the sheet state before assembly Therefore, there is a problem that the storage efficiency is not good.

There was sex.
On the other hand, the storage box (B) has a better function of holding the crossboard (B) than the box (A), but for that purpose, reinforcing columns (R) are arranged at the corners of the box, and the support pieces ( F) and a complicated structure for holding the crossboard (b) was required.
In addition, each of the storage boxes (A) and (B) is provided with a crosspiece (b) only on one of the opposing sides of the box, that is, one of a pair of side surfaces or a pair of wife surfaces. For this reason, there was a case where the supporting area was small and the pressure resistance was insufficient.

As another embodiment, the storage box 1 'shown in FIGS. 5 to 7 is punched into a blank sheet 1'a having an expanded shape as shown in FIG. 5 and assembled. The storage box 1 ′ has substantially the same configuration as the storage box 1 described above, except that the holes 19 and 20 provided at substantially the center of the end plate also serve as insertion ports. The same parts are denoted by the same reference numerals. That is,
The folded plates 9 and 10 are crosspieces 7 and 8 and connecting pieces 9b and 10b.
Are formed at a height substantially the same as that of the rear plates 4 and 5, and when the folded plates 9 and 10 are turned over the rear plates 4 and 5, the insertion holes 11 and 12 at the tips are inserted into the handle holes. 1
9 and 20 are formed. On the lower sides of the handle holes 19, 20, locking projections 29, 30 are formed, which are defined by cuts 29a, 30a and folding lines 29b, 30b. This locking projection 2
9 and 30 are formed such that their ends protrude into the inner periphery of the handle hole. Further, the handle holes 19 and 20 are formed by extending the insertion pieces 11 and 1 formed at the tips of the folded plates 9 and 10.
2 is formed to have a width slightly smaller than the width.

度の高さで足りる。When the depth of the box is made deep as in the storage box 1 'of the present embodiment, if the insertion port is formed on the lower side of the base plate, the folded plate is made to have the same length as the height of the base plate. The extension plates need to be formed. However, if the handle holes 19 and 20 formed in the middle of the end plates 4 and 5 are used as the insertion ports as described above, the folded plates can be used as the cross plates 7 and 8 and the connecting pieces 9b and 10b. Almost the same height as.

1 and 12 are configured so as to be pushed into the handle holes 19 and 20 while being slightly curved and to be disposed inside the locking projections 29 and 30 (see FIG. 7). With this configuration, the insertion pieces 11 and 12 are wider than the handle holes 19 and 20 and do not fall out of the holes, and the insertion pieces 11 and 12 are also pressed by the locking projections 29 and 30. Therefore, the folded plate can be securely fixed.
