ABSTRACT:
A product delivery system for delivering sterile liquid product having a positive shut-off valve to prevent back flow of liquid and air into the system. The product delivery system comprises a compressible reservoir, a flexible delivery element extending from the reservoir, and a shut-off valve movable from a closed position to an opened position, the hollow interior of the delivery element being closed when the shut-off valve is in its closed position and open when the shut-off valve is in its open position to prevent the back flow of the delivered liquid product and air into the delivery element and reservoir to thereby maintain the sterility of the liquid product contained within the reservoir and the delivery element.
