ABSTRACT:
A reusable high efficiency propellant driven apparatus for the dispensing of liquid products, featuring a refillable product container, and a rechargeable propellant housing. The propellant housing may be moved from container to container, to dispense a plurality of products; and a non-completely dispensed container can have the product exhausted by the replacement of a spent propellant housing, with the same or a different housing that does contain propellant. The housing is disposed concentric to the container and preferably both are secured to a single cap. A dual piston construction is employed to provide a hermetically sealed propellant housing. Product and propellant deployment is controlled by the movement of a pair of gaskets.
