<p>The invention relates to foamable liquid dispensers of the type where foamable liquid and air are mixed. The problem associated with foam dispensers is the inconsistency in the foams characteristics when dispensed throughout a range of manual squeeze conditions. The foamer includes a squeeze bottle (10) and a device (20, 30) for simultaneously restricting flow of the compressible fluid (130) and incompressible fluid (140) until a predetermined threshold pressure is developed within the bottle by manual deformation thereof. Thus, foam (170) is not dispensed from the bottle until a pressure is developed within the bottle sufficient to produce a desirable foam.</p> |
