Claim Text:
1. A volumetric displacement device comprising: (a) an outer containment means, and (b) a displacement partition located substantially within said outer containment means so as to form two distinct chambers, a displacement matter chamber and a usable material chamber, and (c) a means for bi-directional transport of usable material between the environment and said usable material chamber, and (d) a means for bi-directional transport of displacement matter between the environment and said displacement matter chamber, and wherein (e) said displacement matter is a compressed gas, and (f) said volumetric displacement device is designed to accept a flexible bottle as said displacement partition, and further comprising (g) a junction separating said outer containment means into a bell and a closure, said junction having an inside diameter large enough to accommodate passage through said junction of the largest outside diameter of said flexible bottle designed to fit said volumetric displacement device, and (h) a usable material valve means for controlling said bi-directional transport of said usable material, and (i) a usable material valve actuation means for actuating said usable material valve means, and (j) a displacement matter forcing means for forcing said displacement matter into said displacement matter chamber, and (k) one or more members selected from a separable outer containment means group consisting of said bell with an interior surface shape that is a section of an ovaloid shape that may be cut or sectioned from a complete ovaloid shape, said closure with an interior surface shape that is a section of an ovaloid shape that may be cut or sectioned from a complete ovaloid shape, said bell with an exterior surface shape that is a section of an ovaloid shape that may be cut or sectioned from a complete ovaloid shape, and said closure with an exterior surface shape that is a section of an ovaloid shape that may be cut or sectioned from a complete ovaloid shape.
