A gas storage and dispensing system, including a gas storage and dispensing vessel, holding a physical adsorbent medium having sorptive affinity for the gas, and desorptive thereof under dispensing conditions. The gas may be an organoleptic gas, a gaseous therapeutic agent, or the like. The gas storage and dispensing system may be constructed with the gas storage and dispensing vessel in gas flow communication with a bladder that is actually manually or mechanically actuated to effect compression and release thereof, to achieve pressure differential-mediated desorption of the gas from the physical adsorbent medium, and discharge of desorbed gas from the vessel.

[ What is claimed is:] [9.] A gas storage and dispensing system, comprising:a gas storage and dispensing vessel;a physical adsorbent material in the vessel having sorptive affinity for the gas, and from which the gas is desorbable under dispensing conditions;a gas sorptively retained on said physical sorbent material; anda dispensing assembly for generating dispensing conditions for desorption of the gas from the physical adsorbent material and discharging desorbed gas from the vessel, said dispensing assembly comprising:a carrier gas source;an inflow passage joining the gas storage and dispensing vessel in fluid flow communication with the carrier gas source;a unidirectional flow control valve in the inflow passage permitting flow only of carrier gas from the carrier gas source into the vessel in response to an underpressure condition in the vessel;a pump;a first outflow passage joining the vessel in fluid flow communication with the pump;a second outflow passage joined in fluid flow communication to the pump and terminating at a discharge end for discharging desorbed gas from the system;wherein the pump is operable to exert pumping action on the vessel for reduction of pressure therein to cause the unidirectional valve in the inflow passage to open in response to underpressure in the vessel and effect flow of the carrier gas into the vessel through the inflow passage, thereby providing said dispensing conditions involving desorption of the gas from the physical adsorbent material and into the carrier gas flow, with said pump effecting flow of desorbed gas through the first and second outflow passages for discharge of desorbed gas from the system at the discharge end of the second outflow passage.
