ABSTRACT:
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 delivery mode. The described volumetric displacement device can operate in a conventional refrigerator.
