<p><P>PROBLEM TO BE SOLVED: To provide an engaged closure box able to close an opening face easily without damaging an accommodated merchandise and also able to withstand a large load. <P>SOLUTION: In pairs of opposite frame panels 1 and 2 of a peripheral wall, an inner closing flap 4 is connected to one of the opposite frame panels 1, and an outer closing flap 5 is connected to the other frame panel 1. Side closing flaps 6 are connected to the frame panels 2 on both sides. The inner closing flap 4 is folded inside. The side closing flaps 6 are superposed on the inner closing flap 4, and then the outer closing flap 5 is superposed on the side closing flap 6. These flaps are engaged with one another, thereby obtaining the engaged closure box for closing the opening face. In this box, a turned-back piece 7 is connected to the leading end of the outer closing flap 5, and the turned-back piece 7 is folded so as to wrap the steps 6a of the side closing flaps 6. The turned-back pieces 7 are then covered with the inner closing flap 4. This prevents the end edges of the turned-back pieces 7 which may strike a surface of an accommodated merchandise from being exposed inside the box. Since the turned-back pieces 7 are pinched between the inner closing flap 4 and side closing flap 6, the closed state of the opening face is kept. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
