ABSTRACT:
A pressing member44is pressed from the outside against a peripheral wall of a can shell4whose interior is maintained at a predetermined pressure by gas, to form a recess-deformed portion56having a predetermined shape on the peripheral wall of the can shell4. Thereby, three-dimensional patterns can be formed by recess-deforming desired portions of the can shell4while preventing the strength of the can shell4from being deteriorated and preventing the inner surface of the can shell4from being scratched or the coating from being damaged, by which outer shape processing with high design performance can be easily applied to the can shell4at a low cost.
