ABSTRACT:
A disposable container for a two-part composition whose plastic shell defines a cavity. A frangible partition of coated aluminum foil divides the cavity into two sealed compartments. A piercing member mounted on a resilient portion of the shell in one compartment has a free end portion transversely directed toward the partition. It pierces the partition when the resilient shell portion is pushed manually inward of the cavity, and the contents in the one compartment may then be pumped into the other compartment by alternatingly pressing and relaxing the resilient shell portion.
