摘要
A can (1) is provided with a mouth part (4), a shoulder part (3), and a body part (2). The shoulder part (3) of the can (1) is decorated, without damaging the shoulder part (3), by forming at least one of a recess and a protrusion by means of a rotating process in which the shoulder part (3) is held between a receiver (11a), having a concave-convex shape, of an inner roll (11) and an outer roll (12) having a convex-concave shape corresponding to the concave-convex shape of the receiver (11a) of the inner roll (11).
