ABSTRACT:
A package for materials that are to be mixed just prior to use comprises a squeezable container into which is inserted a barrel containing a plunger. One substance to be mixed is placed within the container. The second substance is placed within a compartment formed within the barrel between a pair of pistons having flexible sealing rings. Telescoping of the plunger rod into the barrel causes the upper piston to advance into the compartment. The advancing upper piston exerts hydraulic pressure causing the lower sealing piston to detach from the barrel allowing internal mixing of the substances into a mixed fluid. By squeezing the container side wall, mixed fluid may be dispensed from a forward end of the plunger rod communicating with the container interior through a series of passageways.
