STRUCTURE FOR FOLDING CARDBOARD

摘要

PROBLEM TO BE SOLVED: To provide a structure for folding a cardboard which keeps the good appearance of the cardboard with little swell in the body part of the cardboard by a piled up load and is superior in a box making characteristic using a caser. SOLUTION: One ruled line 7 and two ruled lines 8 shifted in parallel are alternatively provided at both sides of a cut line in between a ridge between a rising panel 1 and a flat panel 2. The ridge between the panel 1 and the panel 2 is folded along the lines 7 and 8. When a box adopts this folding structure, vertical deformation is absorbed by the change in the folded degree of the line 8 when a piled up load is applied, and the one-sided fold of the line 8 is prevented by the line 7 part in box making.
