PROBLEM TO BE SOLVED: To contrive to make small a flat area of a housing box when being flatly folded, and facilitate both folding down and building up of the box. SOLUTION: A housing box is equipped with a box main body 11 wherein respectively one pair of side walls 21, 22 are erected from the peripheral edge of a bottom wall 20, and a reinforcing member 12 which is fitted in the box main body 11, and a partitioning member 13 which partitions a space in the box main body 11 into a plurality of sections. At both end sides of the bottom wall 20, a notched part 23 is provided, and one line of a folding part 25 is provided between the notched parts 23. In the meantime, on the side wall 21, one line of a folding part 27 is formed also. By respective folding parts 25, 27, the bottom wall 20 and the side wall 21 can be folded inward so as to be doubly folded, and the size when being folded does not exceed the size of the side wall 22. Also, the notched parts 23 keep the folding resistance of the bottom wall 20 and the side wall 21 to a minimum. |
