ABSTRACT:
A container for storing a product under pressure and dispensing the stored product comprises a container body having screw threads arranged about an opening of the container body, a valve for dispensing a pressurized product from the container, and a closure having screw threads thereon threaded onto the threaded container body for fastening the closure and the valve to the container body to close the opening. One or more passages are provided in the container body and/or the closure for introducing pressurized gas between the closure and container body and into the container through the container opening when the closure is being screwed onto the container body. In a preferred embodiment, the container is a barrier pack container having an inner collapsible container located within the container body to provide separate chambers for propellent and product. The inner collapsible container is sealingly retained onto the valve during assembly of the container at a valve portion having on each of two opposite sides thereof an outwardly flared portion which tapers to an outer tip.
