The storing container 3 is obtained by protruding a standing wall 10 from the outer periphery of one face side of a base fragment 9. The height of each upper edge of both side standing walls 16 and 16 constituting the standing wall 10 is gradually heightened to the tip. When both the storing containers 3 and 3 are folded so as to be closed, the side standing wall 16a and the tip standing wall 19a of one container 3a are overlapped with the inside of the side standing wall 16b and the inside of the tip standing wall 19b of the other storing container 3b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
