<p>PROBLEM TO BE SOLVED: To prevent deformation and stress from being produced in a packaging material by a method wherein the pattern of a fold line of blank is formed so that the fold line conforms to an actual fold line of a final shape of a container, taking into account of thickness of the packaging material formed by forming flaps to prevent the packaging material from extending outward by a distance corresponding to the thickness of folded part. SOLUTION: A blank 1 for packaging a container consists of a plurality of side panels 3 constituting side walls of the container, both end panels, and end panels 4a, b, c forming folded flaps. And an end of a straight line-shaped fold line 7b between the end panel 4b forming a flap to be folded to the side of the end panel and the side panel 3 is offset to the end panel from a straight line-shaped reference fold line 7a between the end panel 4a, which does not form a flap, and the side panel 3.</p> |
