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 slots which act as vents therethrough. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue internal pressurization. The vents to relieve propellant and product therethrough in the event of overpressurization.

An outer container for use in an aerosol dispenser and having a longitudinal axis, the outer container comprising:
- an open top having a crimp ring therearound;
- a shoulder disposed in spaced relationship below the crimp ring;
- a lower neck portion depending from the crimp ring to the shoulder;
- sidewalls depending below the shoulder;
- and
- a closed end bottom joined to the sidewalls,
- the crimp ring having an upper surface and a lower surface opposed thereto, the upper surface and the lower surface being joined by an outer surface, an inside diameter surface being opposed to the outer surface, the inside diameter surface of the crimp ring having a longitudinally oriented vent extending from the upper surface towards the closed end bottom of the outer container;
- a valve cup crimped to the crimp ring, a valve disposed in the valve cup, a product delivery device and propellant disposed in the outer container, the outer container being free from direct contact with product intended for dispensing, the valve cup having an outer wall with at least two circumferentially spaced holes therethrough.

- a shoulder disposed in spaced relationship below the crimp ring,
- a lower neck portion depending from said crimp ring shoulder,
- sidewalls depending below the shoulder,
- a closed end bottom joined to the sidewalls,
- a valve cup joined to the crimp ring, wherein the valve cup comprises an outer wall with a hole therethrough,
- a valve joined to the valve cup for dispensing product from the outer container,
- a product delivery device disposed in the outer container, and propellant disposed in the outer container and in operable relationship with the product delivery device,
- the crimp ring having an upper surface and a lower surface opposed thereto, the upper surface and the lower surface being joined by an outer surface, an inside diameter surface being opposed to the outer surface, at least one of the inner diameter surface and the outer surface of said crimp ring having at least one longitudinally oriented vent extending from said upper surface towards the closed end bottom of the outer container.
