A system and method are provided for failsafe storage and dispensing of a liquid material from a container having a storage compartment. The system includes a container, a collapsible receptacle disposed within the container, and a disposing control unit coupled to the container. The container defines a storage compartment and an access opening in communication therewith, while the collapsible receptacle is disposed within the storage compartment for sealed storage of the liquid material therein. The dispensing control unit includes a control valve portion operable to selectively direct a flow path of at least a portion of a pressurized fluid stream that it receives. The dispensing control unit further includes a response valve portion coupled to the collapsible receptacle which is reconfigurable responsive to the pressurized fluid stream directed selectively thereto by the control valve portion to alternatively seal and open the collapsible receptacle. The response valve portion is resiliently biased to a configuration whereby release of the liquid material therethrough is prevented in the absence of suitable fluid pressure actuation.
