Method and apparatus for making a thin walled cover for an aerosol container

摘要

The invention concerns a method of making an aerosol container having a cover (60) with an outer periphery and having a container body (20) with an open end, said cover (60) being thin walled to be deformable by elevated gas pressure in the interior of said container and said cover having a countersunk recess (62) in the vicinity of its outer periphery, the steps comprising: attaching said cover to said open end of said container body (20) to define a container interior and to seal said container interior; and pressurizing said container interior with gas to a pressure sufficient to cause said thin walled cover (60) to evert outwardly to substantially eliminate said countersunk recess (62).
