Abstract
Abstract A pressurized mixing and dispensing device has an inner container disposed within an outer container. The dip tubes are in the inner container, one tube passing through inner container bottom to a point near the bottom of the outer container and the other going to a point near the bottom of the inner container. Both tubes are connected to outlets in the inner container, which communicate through a valve housing seated in inner container with a valve core disposed in the bore of the valve housing. The valve core has grooves in its surface in which are formed flow restricting protuberances. The core grooves are connected to the container outlets when axial force is applied to the valve core. That axial force causes the core to move axially and rotatably because of a camming pin which extends from the valve core through a camming aperture in the housing against the resistance of a spring connected between the core and the housing. A seal surrounds the valve core just below the grooves.
