Abstract

PURPOSE:To improve mass productivity by forming a cap and a a stem by plastic deformation from a material. CONSTITUTION:The side of a cylindrical product 5 with a metallic bottom such as steel or the like is compressed in a central axis direction 10 of the cylinder with uniform force. At this time, a stem is left without applying force to the bottom. In this composition, a connecting process is unnecessary and costs will be reduced and it is advantage for mass production. And no welding points make good airtightness.
