PROBLEM TO BE SOLVED: To provide a packaging box having a structure which can house goods twice or more times as much as the conventional structure and can be constructed easily and produced at a low cost, by housing goods in vertically divided inner space of the packaging box. SOLUTION: A piece of sheet cut in a predetermined shape is folded along predetermined creases, thereby constructing the packaging box 2 having a bottom and front and rear side-walls and left and right side-walls all of which surround the bottom. In the packaging box 2, inner flaps extend from both left and right ends of the front and rear side walls 20 and 60. A sheet 10 is fitted in grooves formed in projecting beads formed in parts of the inner flaps, thus vertically dividing the inner space of the packaging box 2. COPYRIGHT: (C)2004,JPO
