Projections 11a are formed at an upper end of the end wall 2. Belt-like parts 11c are formed at the end part of the top plate 3 along a cut line 11b extending from around a boundary with the side wall 1 to the tip side. The convex part 11 is formed with a belt like part 11c pushed up by the projection 11a. The concave part 12 is formed with an end edge of a bottom plate 4, which overlaps with a front surface side of a bottom flap 7 connected to a lower end of the end wall 2, and which is cut into the inner side.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2017,JPO&INPIT
