Abstract
A container and valve assembly for storing and dispensing substances including edible substances. The container has a body that has a storage chamber for storing the substance and a head portion for holding the valve assembly. The valve assembly includes a valve body and a valve seat surrounded by a flexible outer cover that includes a valve portion. A seam between the valve portion and valve seat form a one-way release valve wherein a portion of the seam remains closed when the substance is dispensed. To dispense the substance, pressure is applied to the body forcing the substance into the valve assembly, which in turn, controls the flow and release of the substance without exposing the remaining substance to the external atmosphere; thus, the sterility of the storage chamber and remaining substance is maintained, and the shelf life of the substance is increased.
