Claims

[Scope of utility model registration request]

A side plate piece is attached to each side of the square bottom plate, a cover plate piece is attached to one set of opposing side plate pieces, and an inner folding piece and an outer folding piece are attached to each outer side of the other set of side plate pieces. A sheet material in which each folding piece is connected via a hinge part is formed from a laminated material of a foamed synthetic resin layer and a paperboard layer, and this sheet material is folded by each hinge part, and the foamed synthetic resin layer is folded. In the assembly box whose inner surface can be assembled into a box shape, the sheet material is formed from a laminated material in which a highly rigid non-foamed synthetic resin layer is provided between a foamed synthetic resin layer and a paperboard layer. The foamed synthetic resin layer and the non-foamed synthetic resin layer are partially bulged in the bottom plate and side plate pieces, or further in the cover plate piece and outer folding piece, and both layers have a plurality of bulges. An assembly box characterized in that an air chamber is formed between the bulging portion and the paperboard layer.
