ABSTRACT:
A non-venting fluid dispenser system, for example being a collapsible flaccid bag loosely suspended in a sleeve and exposed to atmospheric pressure. A non-venting aspirator and a pressure actuated valve are mounted on the sleeve and close the bag. Operation of the aspirator promotes a low pressure on the outward side of the valve and atmospheric pressure acting against the bag drives fluid product through the valve and into the aspirator for dispensing, whereby the bag progressively collapses as fluid is expelled. The pressure actuated valve blocks against back flow entry of air into the bag.
