Further, lower flaps 6a and 6a and upper flaps 7a and 7a are provided on opposite sides of the bottom plate 1 and the top plate 3, respectively. These upper and lower flaps overlap each other on the inner flaps 5a and 5b at the time of assembly. The upper and lower flaps are set to have a length that is half or less of the width of the pair of side plates.
[0012]
And on the pair of side plates 2a, 2b and the front and rear inner flaps 5a, 5a and 5b, 5b, a pair of tape-shaped cut portions 8a, 8b are provided in parallel with the bottom plate in between, and one end thereof Let the part face the tip of the inner flap.
[0013]
As shown in FIGS. 1 to 4, a handle 6b having a hand hole 6c is formed at the center of the tip of the lower flap 6a so as to project in a T-type or an inverted T-type.
In addition, the said handle and the said upper flap are shown by FIG.1 and FIG.2, and these are formed so that they may have a length relationship which mutually overlaps (polymerizes). Moreover, the hand hole in the handle with a hand hole is formed in the relationship which does not overlap with an upper flap. However, such a relationship is not an essential requirement in the present invention.
[0014]
The case of the present invention configured as described above is formed by die-cutting double-sided cardboard or cardboard that is substantially equivalent to this sheet. When die-cutting a corrugated cardboard sheet, the cut tape is pasted on the pair of side plates 2a, 2b and the inner flaps 5a, 5a, 5b, 5b before and after the pair of side plates 2a, 2b simultaneously, or by post-processing, so This is referred to as a drawer 9 of the part. In this way, the pair of tape-shaped cutting portions 8a and 8b are provided in parallel in the left-right direction across the bottom plate.
