Abstract

A cylindrical packing case extending in an upper-lower direction, comprising an upper unit, a lower unit provided with a front side surface and a rear side surface in the circumferential direction, a pair of convex folding units upwardly extending from the front side surface and the rear side surface of the lower unit. A first weak line is provided along a first boundary between the upper unit and the convex folding unit, a second weak line is provided along a second boundary in the circumferential direction between the upper unit and the lower unit. A first folding ruled line is provided in the circumferential direction between the convex folding unit and the lower unit, and a second folding ruled line extending in the upper-lower direction continuing from between the front side surface and the rear side surface of the lower unit, is provided in the convex folding unit.
