Further, it is also possible to provide a notch 22, such as a semicircular shape, at the center of the outer end as appropriate.

Further, a continuous trough portion 23 is provided at the upper part of the folded piece 20.

On the other hand, each of the side pieces 8 is provided with a sub-lid piece 25 through a fold 24.
An insertion piece 27 is connected to the lid side wall 10 via a fold 26.

If the sub-lid piece 25 is formed to have the same width as the reinforcing tongue piece 21,
The left and right outer lines are in a straight line, and no cut portion is created when paper is removed from the paper.

Further, the insertion piece 27 may be provided with a cutout portion 28 for locking with the lid portion 18 as appropriate.

As shown in FIG. 2, a folding piece 20 is folded and pasted onto the lid portion 18 of the main body constructed in this way through a fold 19.

When pasting, if the upper part of the folded piece 20 is not attached to the lid part 18, it becomes possible to insert the insertion piece 27 between the folded piece 20 and the lid part 18, and when inserting it, The trough 23 provided at the top of the folded piece 20 makes it even easier to make.

In addition, the bottom part 1, the upper wall 9, and the lid side wall 10 each have a side piece 8 and a reinforcing piece 11 folded back through the folds 3 and 5 degrees 29, and the side wall part 6 and the folded part 15 are folded back. Attach parts 7 and 16 except for.

In this way, the side wall portion 6 after assembly is formed in a state that it is inserted into the main body as shown in FIG. 5, so that the side wall portion 6 has excellent pressure resistance.

Moreover, as already mentioned, when the reinforcing piece 11 formed by slightly extending its own open piece is folded back, this reinforcing piece 11
The lid side wall 10 that faces the folded part 15 except for the folded part 15
By attaching it to the and insertion piece 27, the strength of the lid side wall 10 itself can be further increased.

The upper wall 9 and the lid side wall 10 are attached with the respective adhesive parts 16 and 7 of the reinforcing piece 11 and the side piece 8, which are integrally connected, so that the folded part 15 is attached to the upper wall 9 and the lid side wall 10 through the fold line 14. If the upper wall 9 and the lid side wall 10 are folded up through the folds 2 and 26, respectively, while folding into the inside as shown in FIG. will stand up.

The lid part 18 and the sub-lid piece 25 are folded parallel to the bottom surface through fold lines 17 and 24, respectively, and folded back in the direction of the lid part 18 through fold lines 26. Include piece 27,
