PROBLEM TO BE SOLVED: To provide a box which is used to store an article in the box and allows the sure and quick work of changing the state of the box from a folded state to a storage state and vice versa. SOLUTION: When a lid member 6 is turned upward when the box is in the folded state, side members 3 and 4 extend automatically as a bottom member 5 turns downward automatically to constitute the box A in the storage state. The box A is folded by descending a pulling member while pushing a front member 2 toward a back member 1. COPYRIGHT: (C)2010,JPO&INPIT
