Patent ID: 6868851

Claim:
Liquid reservoir means for supplying liquid to a nebulizer for atomization, said liquid reservoir means comprising the combination of: a liquid reservoir formed of first and second membranes positioned in a generally opposing relationship to form a closed chamber between the membranes for containing liquid, said first and second membranes being formed of a resilient material, said first and second membranes having opposing surfaces which are contiguous when the chamber is empty and spaced when said chamber is filled with liquid and thereby expanded, the expansion of the chamber distending said resilient material membranes to cause said resilient material membranes to apply pressure to liquid in the said chamber; flow control means in communication with the chamber for controlling the discharge of liquid from the reservoir to the nebulizer under the pressure applied to the liquid by the distended resilient material membranes; and a member in the nebulizer having a surface on which one of said first and second membranes is contiguous and which receives said flow control means, said surface of said member being formed to deform at least one of said first and second membranes as a result of the contiguity of the membrane on the member to further increase the pressure on the liquid in said chamber.
