A volumetric displacement device, especially good for preserving and dispensing carbonated beverages has been constructed that is extremely light, small, safe, attractive, easy to use, energy efficient and inexpensive. It can use battery power, has an ovaloid shape, can be constructed of thin flexible plastics, and operates in various positions that eliminate the need for a pickup tube. A consistent problem with soda savers, in that they destroy carbonated beverages by delivering them in a violent manner, has been solved by utilizing a low pressure deliv...


I claim: 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 displace...
