Abstract
A preform of a can includes: a dome part being concave into the bottomed cylindrical body; and an annular leg part projecting in a direction opposite to a direction in which the dome part is concave, the dome part and the annular part being molded to form the preform of the can, and an inner surface of the dome part being pressed to mold a molded can. A maximum height of the preform of the can from a ground plane to the dome part is greater than a maximum height of the molded can from a ground plane to the dome part. In a vertical cross-sectional view, a length of an inner peripheral section of the leg part connecting between a ground point of the leg part and the dome part of the preform of the can is greater than a length of a curved end molded around the dome part of the molded can.
