ABSTRACT:
Resiliently squeezable container is disclosed which is partitioned into two chambers, an ingredient chamber, which communicates through a discharge orifice to the outside, and an air chamber which communicates through a 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 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.
