PROBLEM TO BE SOLVED: To obtain a manufacturing method of an aerosol can of a slot shoulder type capable of stabilizing a shoulder shape and improving a dimensional precision. SOLUTION: In a pre working process, a straight part 5 inclined at an inclined angle α is formed in the section transferring from a shoulder part 3 to a barrel part 4, in a next grooving process, while abutting a tool 8 on the straight part 5 and regulating, the vertical straight part 5 is formed, further a groove part 7 is formed at the lower end of the straight part. |
