PROBLEM TO BE SOLVED: To effectively restrain the occurrence of such inconvenience that an insertion piece 4B cannot be inserted/extracted to/from a notch part 4A.SOLUTION: A storage cylinder 2 is constituted by bending and forming one sheet in a polygonal cylindrical shape, and also sticking an outside flap S1 and an inside flap S2 together. A lid part 3 is constituted by sticking the outside flap S1 and the inside flap S2 together, and the inside flap S2 is linked with an inside design surface S3 via a fold line L1. Thus, a relative position of the insertion piece 4B to the notch part 4A becomes accuracy of a position when forming the notch part 4A and the insertion piece 4B on a sheet (a development sheet) before bending without being influenced by a bending position and a sticking position of a sheet S. Thus, the occurrence of such inconvenience that the insertion piece 4B cannot be inserted/extracted to/from the notch part 4A, can be effectively restrained.SELECTED DRAWING: Figure 1 |
