PROBLEM TO BE SOLVED: To provide a box, whose top face can be easily sealed with a locking structure, so that the use of an adhesive tape or staples for sealing the top face is eliminated. SOLUTION: According to the box, flaps for forming the top face comprises a pair of inner flaps formed on width faces, and a pair of outer flaps formed on length faces with the front end of each outer flap formed to be abutted against each other. On each outer flap, a closing stopper is formed at the center of the front end. On each inner flap, a handling hole is formed at the center while a pair of incision grooves are formed at the left and right of the front end, respectively. The incision grooves of the inner flaps are engaged with the closing stoppers of the outer flaps, respectively, to lock both inner and outer flaps together. COPYRIGHT: (C)2004,JPO
