摘要

An improved aerosol assembly and method of making same is disclosed for an aerosol container having a container sealing bead disposed about an upper opening in the aerosol container. The invention includes a mounting cup having a mounting cup sealing rim extending about the periphery thereof. A valve assembly is disposed in the mounting cup for providing fluid communication between the interior of the aerosol container and the exterior of the aerosol container. A sealing gasket is electrostatically applied to one of the sealing beads or the sealing rim for providing a fluid tight seal when the mounting cup is secured to the aerosol container. The invention also includes the method of electrostatically applying a resilient material for providing the seal between the mounting cup and the aerosol container. A particular embodiment of the invention provides a combined scaling gasket and protective coating for the mounting cup with either a uniform or preferential coating thickness.
