Patent ID: 7753288

Claim:
A system for failsafe storage and dispensing of a liquid material comprising: a container having a storage compartment for the liquid material and a neck portion defining an access opening in communication with said storage compartment; and, a dispensing control unit coupled to said container, said dispensing control unit including: a control valve portion operable to selectively direct a flow path of at least a portion of a pressurized fluid stream received thereby, the flow path being defined entirely outside said storage compartment; and, a response valve portion coupled to said neck portion, said response valve portion being reconfigurable between first and second states responsive to the pressurized fluid stream selectively directed thereto by said control valve portion, said response valve portion in said first state sealing said access opening against communication with said storage compartment, and in said second state maintaining said access opening in communication with said storage compartment; said response valve portion being resiliently biased to said first state, the system maintaining the pressurized fluid stream within the flow path, whereby release of the liquid material therethrough is prevented in the absence of suitable fluid pressure actuation therefor.
