Abstract: A resiliently squeezable container is disclosed which is partitioned by a resilient deformable membrane into two chambers, an ingredient chamber, which communicates through an ingredient discharge orifice to the outside, and an air chamber which communicates through a simplistic reclosable valve to the ambient atmosphere. The reclosable valve is such that the pressure within each chamber is held in equilibrium. Thus, on squeezing of the container ingredients are exuded from the ingredient chamber and on release of the container (recovery) air enters through the reclosable valve into the air chamber to re-establish equilibrium between chambers within the container. Thus, by cyclically squeezing and releasing the container, ingredients in the container are instantaneously discharged during each squeeze portion of the cycle. The invention resides in the reclosable air valve which utilizes as the movable element of the valve a portion of the resilient deformable membrane.

The reclosable valve is such that the pressure within each chamber is held in equilibrium. Thus, on squeezing of the container ingredients are exuded from the ingredient container and on release of the container air enters through the reclosable valve into the air chamber to re-establish equilibrium within the container. Thus, on a separate cyling or squeezing, the ingredient is instantaneously available for discharge.
