Aerosol dispenser with polygonal crimp ring outer container therefor and preform therefor

Abstract:

An aerosol dispenser, an outer container for an aerosol dispenser and a preform for an outer container. The aerosol dispenser, outer container and preform each have a neck, which in turn has a crimp ring, to receive a valve cup clinched thereto. The crimp ring has a polygonal cross section providing alternating flat sides and vertices. The flat sides both function as integral vents and allow parallel translation of mold cavities so that a two piece molding apparatus may be used.
