Abstract
Disclosed is a packing can having a circumferential polyhedral wall formed on a can barrel, in which as compared with boundary ridgelines of structural unit faces of the polyhedral wall and crossing points of these boundary ridgelines, the structural unit faces are convex to the interior of the can and the structural unit faces are arranged so that adjacent rows of structural unit faces have a phase difference in the axial direction of the can. This packing can has a very high strength against deformation by application of the external pressure. Furthermore, in preparing this packing can, damage of a coating layer formed on a metal sheet used as the can barrel blank can be effectively prevented.
