Patent number: 8746512Abstract: A sealing structure which seals a container body and an aerosol valve without providing a seal member between them. An aerosol container employing the seal structure comprises a bottomed cylinder like container body and an aerosol valve firmly fixed to the opening of the container body. The seal structure between the container body of the aerosol container and the aerosol valve is formed of a valve support portion of the container body and a step portion of the aerosol valve. The aerosol container is manufactured by deforming a corner of the step portion into a curved surface shape from a square shape by applying an annular force to the step portion from a convex surface by plastically deforming a lower part of a cover cap and a part of the container body while pushing the cover cap downward.Type: GrantFiled: October 8, 2009Date of Patent: June 10, 2014Assignee: Daizo CorporationInventors: Hidetoshi Miyamoto, Keiichiro Teramoto, Tatsuya Nakamuro, Masaomi Takahashi
