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 including a crimp ring. The crimp ring may be configured to receive a valve cup, which is clinched thereto. The crimp ring includes one or more vents. The vents may be used to control overpressurization within the dispenser. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue overpressurization. The vents allow propellant and/or product to be released therethrough in the event of overpressurization.
