Abstract

A mixing valve assembly (16) is provided for a container structure (10). The mixing valve assembly includes a valve stem (132) having an inlet (134) within the container structure and an outlet (136) external of the container structure. The valve stem is movable between a first position wherein the composition is retained in the container structure and a second depressed position wherein the composition exits the container structure through the outlet of the valve stem. A generally concave biasing structure (156) extends from the valve stem and urges the valve stem toward the first position.
