<p>An apparatus that provides for withdrawal of the liquid contents from a closed container (14) independent of the spatial orientation thereof, is described. The liquid withdrawal apparatus includes flexible withdrawal conduit (58) disposed inside the container and in fluid flow communication with external heat exchangers (144, 146). The heat exchangers serve to transfer heat to the withdrawn liquid to thereby provide a breathable gas mixture. The upstream end of the withdrawal conduit (58) are provided with a weighted pick-up means comprising a wicking material that draws liquid into the interior thereof to ensure contact of the liquid with the conduits, even when the supply of liquid is nearly depleted. A pressure differential between the inside of the container and the external heat exchangers, normally brought about by an inhalation event of the user, provides the motive force for withdrawing the liquid contents from the container through the conduits.</p> |
