1st level the board (1) almost is inside same plane form and, and in order to form the hollow capacity body, the part of the board (2, 3 and 4) one side vis-a-vis on the other hand 2nd it is formed hinge expedient (30) by bending with around it is possible to take with the form which is bent in the board which is beforehand judged in order to form the part of the board of 1 sets, the aforementioned board (1) 1st, 2nd and 3rd at least three layer (21, 22 and 23) mutually laminationIt is formed by doing, the description above which features that 1st layer (21) with 3rd layer (23) with the 2nd layer which was put between (22) is layer of the soft material, is the layer whose among 1st and 3rd two layers 1st layer is hard at least relatively the board which is judged beforehand is offered. Hinge expedient (30), among 1st and 3rd two layers, 1st layer (21), you bend at least and the line (34) parallel and it is desirable the 1st it is formed groove (33) to have at least.
