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.

A preform for use in an outer container of an aerosol dispenser and having a longitudinal axis, said preform comprising:
- an open top having a crimp ring therearound,
- sidewalls depending from said open top, and a closed end bottom joined to said sidewalls,
- said crimp ring having an upper surface and a lower surface opposed thereto, said upper surface and said lower surface being joined by an outer surface defining an outer circumference, said outer surface of said crimp ring defining a circumference, said circumference of said outer surface being polygonal.
An outer container for use in an aerosol dispenser and having a longitudinal axis, said outer container comprising:
- an open top having a crimp ring therearound,
- a shoulder disposed in spaced relationship below said crimp ring,
- a lower neck portion depending from said crimp ring to said shoulder,
- sidewalls depending below said shoulder, and
- a closed end bottom joined to said sidewalls,
- said crimp ring having an upper surface and a lower surface opposed thereto, said upper surface and said lower surface being joined by an outer surface, an inside diameter surface being opposed to said outer surface, said outer surface of said crimp ring having a polygonally shaped outer surface.
An aerosol dispenser for dispensing a product therefrom and having a longitudinal axis, said aerosol dispenser comprising:
- an outer container having an open top with a crimp ring therearound,
- a shoulder disposed in spaced relationship below said crimp ring,
- a lower neck portion depending from said crimp ring to said shoulder, sidewalls depending below said shoulder,
- a closed end bottom joined to said sidewalls,
- a valve cup joined to said crimp ring,
- a valve joined to said valve cup for dispensing product from said outer container,
- a product delivery device disposed in said outer container, and
- propellant disposed in said outer container and in operable relationship with said product delivery device,
- said crimp ring having said crimp ring having an upper surface and a lower surface opposed thereto, said upper surface and said lower surface being joined by a polygonal outer surface.
