Abstract:
A method of forming a gasket for a mounting cup for closing an aerosol container having a beaded opening, said mounting cup having a central pedestal portion for crimping an aerosol valve, a profile portion having a radially outer terminus emerging outward from the pedestal portion, a body portion extending upwardly from the radially outer terminus of the profile portion, said body portion having an upper portion emerging into a channel portion which terminates in a skirt portion, said channel portion being adapted to receive the bead of an aerosol container for clinching thereto comprising:a) disposing a sleeve of gasket material along the body portion of the mounting cup; b) advancing the sleeve of gasket material into the channel portion of the mounting cup and thereat forming a continuous fold-line in the gasket material and thereby creating a segment of gasket material on each side of the fold line; c) folding one segment of the gasket against the other segment to form a folded-over gasket having overlapping free edges; and d) positioning the folded-over gasket along the upper portion of the body portion and extending a limited distance into the channel portion, the folded-over gasket being disposed such that one of the overlapped free edges of the gasket is distal to the channel portion.
