<P>PROBLEM TO BE SOLVED: To minimize waste corrugated cardboard when manufacturing corrugated cardboard boxes from corrugated cardboard, and prevent buckling of the corrugated cardboard boxes and deformation and damage of stored objects inside the boxes. <P>SOLUTION: The corrugated cardboard box 1A includes closing parts 8 on upper and lower sides of a body part 7 surrounded by side wall 6. Inner flaps 4 continuing to the side walls opposing to each other are folded in the closing part 8 of the corrugated cardboard box 1A, and a flap absence region 2a is formed between the folded inner flaps 4. Outer flaps 5 are overlapped with outer sides of the inner flaps 4. The inner flap 4 has a cut line 20 for separating part of the inner flap or cut lines and folding lines for reversing part of the inner flap, and separation pieces formed by separating part of the inner flaps 4 and/or reverse pieces formed by reversing part of the inner flaps can supplement the inner flap absence region 2a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
