PROBLEM TO BE SOLVED: To enable to stand side walls under a laid down condition rapidly, surely and approximately vertically. SOLUTION: A female hinge member H1 having a long hole h1 and a connecting hole h2 formed in a horizontal part 1a2 of the bank part, a vertical slit h3 formed in the inside vertical part 1a1, a hook h5 for preventing a horizontal side wall from being raised up formed on the inner face of a tongue piece h4, and a hook h6 for preventing a vertical side wall from being raised up formed on the inside vertical part positioned on the opposite side to the tongue piece, is arranged. A female hinge member H2 having a supporting piece h10, a block h11 for preventing the horizontal side wall from being raised up crosslinking the supporting piece, and a block h12 for preventing the vertical side wall from being raised up formed on the outside face of the supporting piece, is arranged. By connecting the female hinge member with the male hinge member, the side wall is connected with the bottom part. As a result, as in the conventional case, there is no concern of bringing an engaging block into contact with the bank part of the bottom part, or running aground on the bank part. Therefore, it is possible to stand the side walls under the laid down condition rapidly, surely and approximately vertically. COPYRIGHT: (C)2009,JPO&INPIT
