ABSTRACT:
A squeeze bottle foam dispenser with improved foam consistency throughout the range of manual squeeze conditions. The foamer includes a pressure operated valve for simultaneously restricting flow of the compressible and incompressible fluids until a predetermined threshold pressure is developed within the bottle by manual deformation thereof. Thus, foam is not dispensed from the container until a pressure is developed within the bottle sufficient to produce a desirable foam. The disclosed foamer is for storage and operation in the inverted orientation. This avoids the necessity of an extended spout and its concomitant problems.
