Abstract
A dispensing system is provided for two, constituent, fluent materials which are stored separately and then combined in a dispensing process to form a combination product. The dispensing system includes a container having at least two interior storage chambers, and each chamber has a separate discharge opening. Associated with each discharge opening is a separate, flexible valve. Each valve has an initially closed dispensing orifice which opens in response to a differential between the pressure acting against the side of the closed valve facing toward the associated discharge opening and the pressure acting against the side of the closed valve facing away from the associated discharge opening. In a preferred embodiment, a top is provided downstream of the valve. The top is movable between (1) a close position to occlude a dispensing flow path downstream of the valves, and (2) an open position which permits flow to be discharged from the system.
