Apparatus and method for the series production of a valve mounting cup provided with a gasket for an aerosal container, and such a valve mounting cup

摘要

1. Method for the mass production of an aerosol container mounting cup (10; 34; 98; 118; 234; 242) bearing a gasket (26; 30; 116; 230; 244; 292), the mounting cup having a cross panel (12; 113), an axial sidewall (14) surrounding the periphery at the cross panel and an annular channel (18; 294) extending outwardly from the sidewall, comprising a) forming a band (26; 30; 116; 230; 244; 292) of gasket material on the sidewall (14) of the mounting cup, which band extends above the cross panel (12; 113) of the cup, b) initially advancing the band of gasket material onto the widewall of the mounting cup to a first position, in which the gasket material distal from the annular channel of the mounting cup is positioned at or below the periphery of the cross panel (12; 113) of the mounting cup, c) heating the band of gasket material and d) then advancing the band of gasket material to its ultimate position on the mounting cup and simultaneously causing a deformation of the gasket material, characterized in that during the deformation accumulations of the gasket material are being produced at different positions.
