Abstract

A barrier type product container wherein product is contained at atmospheric pressure and separate from a pressurizing gas. And, mounted thereon, for example, a valve actuator that preferably includes an ejector pump type nozzle element that is valvingly positionable to facilitate ventilating inflow of ambient air into the container and dispensation of product. The nozzle element is also positionable to inhibit ventilation of the container and effluence of product, and facilitate use of ambient air to purgingly dispel product residue from discharge passageways of the nozzle.
