<p>PROBLEM TO BE SOLVED: To prevent a commodity from coming off, and to facilitate the assembly and insertion of the commodity. SOLUTION: Side plates 2 are continuously provided on both side edges 2 of a bottom plate 1, end plates 3 are continuously provided on both side edges of each side plate 2, a notch 7 is provided in the end of each end plate 3, both side plates 2 are erected from the bottom plate 1, a pair of end plates 3 are engaged by mutual insertion of the notch 7 to close the end face, a top side is closed by a lid plate 4 extended from the side plates 2, and the oscillation of the side plates 2 is locked by a locking piece 6 engaged with a handle piece 5. Since the bottom plate 1 is connected to both side plates 2, the bottom plate does not come off. Since the oscillation of the side plates 2 is locked, commodities do not come off of the end face or the top face respectively closed by the end plate 3 and the lid plate 4 connected thereto. The assembly of flaps at the bottom surface or pasting of peripheral walls during the assembly is unnecessary, and the commodities can be easily inserted with the top face largely opened by shallowly engaging a pair of end plates 3 with each other.</p> |
