摘要：
A DEVICE FOR CONTROLLABLY RELEASING A FLUID INTO AN AMBIENT ENVIRONMENT. ACCORDING TO A PARTICULAR EMBODIMENT OF THE PRESENT INVENTION, THE DEVICE COMPRISES A HOUSING HAVING A FLUID COMPARTMENT (5) AND AN ORIFICE COMPARTMENT (7) DISPOSED ADJACENT THERETO AND IN FLUID COMMUNICATION THEREWITH VIA AN ORIFICE. THE FLUID COMPARTMENT (5) CONTAINS THE FLUID FOR RELEASE TO THE AMBIENT ENVIRONMENT. THE ORIFICE COMPARTMENT (7) INCLUDES A FLUID EXIT OPENING COVERED BY A REMOVABLE SEALING ELEMENT (31) AND CONTAINS AN INITIAL QUANTITY OF FLUID WHEN THE DEVICE IS IN AN INACTIVATED STATE. A FLUID RESTRICTOR (25) IS DISPOSED ADJACENT THE ORIFICE TO RESTRICT FLUID FLOW FROM THE FLUID COMPARTMENT (5) INTO THE ORIFICE COMPARTMENT (7) IN THE INACTIVATED STATE. A GAS-GENERATING CELL (9) IS IN SELECTIVE COMMUNICATION WITH THE FLUID COMPARTMENT (5) SUCH THAT GAS GENERATED BY THE CELL (9) IS DIRECTED INTO THE FLUID COMPARTMENT (5) WHEN THE DEVICE IS IN AN ACTIVATED STATE. A FLUID MEMBRANE (17) IS DISPOSED BETWEEN THE GAS-GENERATING CELL (9) AND THE FLUID COMPARTMENT (5) THAT ALLOWS THE GAS GENERATED BY THE CELL (9) TO PASS THERE THROUGH TO THE FLUID COMPARTMENT (5) IN THE ACTIVATED STATE WHILE PREVENTING FLUID WITHIN THE FLUID CONTAINER FROM PASSING THERE THROUGH TO THE CELL (9) IN THE INACTIVATED STATE. THE DEVICE IS ACTIVATED BY REMOVING THE SEALING ELEMENT (31) TO ALLOW THE INITIAL QUANTITY OF FLUID TO EXIT OUT OF THE ORIFICE COMPARTMENT (7) VIA THE FLUID EXIT OPENING AND ACTIVATING THE CELL (9) TO GENERATE GAS AND FORCE FLUID FROM THE FLUID COMPARTMENT (5) TO THE ORIFICE COMPARTMENT (7) AND OUT THE FLUID EXIT OPENING IN A CONTROLLED MANNER.
