摘要： A method of forming the outline of a can shell, comprising the step of pressing, from the outside, a pressing member (44), against the peripheral wall of the can shell (4) having an inside maintained at a specified pressure with gas to form recess-deformed parts (56) of a specified shape in the peripheral wall of the can shell (4), whereby the strength of the can shell (4) can be prevented from lowering and the inner surface of the can shell (4) can be prevented from being scratched, and film on the inner surface of the can shell can be surely prevented from being damaged, three-dimensional patterns can be formed by recess-deforming the can shell (4) at specified positions, and an outline formation with a high designability can be easily applied to the can shell (4) at a low cost.

摘要： A pressing member 44 is pressed from the outside against a peripheral wall of a can shell 4 whose interior is maintained at a predetermined pressure by gas, to form a recess-deformed portion 56 having a predetermined shape on the peripheral wall of the can shell 4. Thereby, three-dimensional patterns can be formed by recess-deforming desired portions of the can shell 4 while preventing the strength of the can shell 4 from being deteriorated and preventing the inner surface of the can shell 4 from being scratched or the coating from being damaged, by which outer shape processing with high design performance can be easily applied to the can shell 4 at a low cost.
