CREASE STRUCTURE OF MULTI-LAYERED CORRUGATED FIBERBOARD AND MULTI-LAYERED CORRUGATED FIBERBOARD CONTAINER INCLUDING THE STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To provide a crease structure of multi-layered corrugated fiberboard which has improved storability and assemblability before assembly by making a folding piece easy to fold and preventing a crease from weakening, and to provide a multi-layered corrugated fiberboard container including the structure. PSOLUTION: The crease structure of multi-layered corrugated fiberboard has the folding piece 11 formed at an end of a corrugated fiberboard base material 10, which can be folded along the crease 12. The crease 12 is formed, on the surface 11a on the folding side, with a continuous cut 12a consisting of consecutive cuts of a predetermined depth and a crushed dent 12b pressed into a recessed cross section along the continuous cut 12a. It is further formed, on the rear face 11b on the surface of the folding side, with an intermittent cut 12c comprising intermittently-formed cuts 12c1 of a predetermined depth extending along the continuous cut 12a.
