ABSTRACT:
An apparatus for storing and selectively dispensing sterile liquids comprises a liquid filled sealed flexible bag which has an integral dispensing spout formed therein. The flexible bag is received within a two piece housing which has spring mechanism to engage and exert pressure on the bag once the two pieces of the housing are closed together. A valve is mounted to the housing and engages the spout of the bag, effectively closing off the dispensing orifice of the spout. The valve is operable to move away from the spout to selectively dispense the pressurized sterile liquid from the bag.
