Abstract: 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.

Abstract: To provide a sealing structure which seals a container body and an aerosol valve without providing a seal member between them, an aerosol container equipped with the sealing structure, and a method for manufacturing the aerosol container, An aerosol container comprising a bottomed cylinder like container body 11 and an aerosol valve 12 firmly fixed to the opening of the container body. A seal structure between the container body 11 of an aerosol container 10 and an aerosol valve 12 is formed of a valve support portion 14 of the container body and a step portion 28 of the aerosol valve.
