着によってシールを行なうものである。2. Description of the Related Art Conventionally, such a sealing device uses a male screw body having a flange portion and a ring-shaped gasket made of a relatively soft metal such as copper or aluminum. This gasket is usually flat on both sides, and sealing is achieved by pressure bonding between these surfaces and the sealing surfaces of the container and male threaded body.

上させるものである。[0003] Japanese Utility Model Publication No. 57-59952 describes such a gasket in which protrusions are provided on both sides. By providing protrusions, this increases the surface pressure between each protrusion and the sealing surface of the container and male threaded body, thereby increasing the degree of crimping between them and improving sealing performance compared to conventional methods. It is something.
