Blank sheet for packaging box

Abstract

This article is a blank sheet that is assembled into a packaging box. The part to which a design registration is sought is the part related to the ruled line between the bottom surface and the long side surface of the assembled packaging box, and the ruled line is in a wavy curved form. As a result, the strength of the box is improved and distortion is reduced. When stacking the boxes, stability between the upper and lower boxes can be obtained, surface and line contact is ensured, and breakage and rattling can be suppressed.
