Abstract
Abstract Disclosed herein is a cartridge for controllably dispensing a liquid substance, which cartridge includes a sealed envelope or package comprising first and second plies of a plastic material which is permeable to the liquid substance, each of the plies formed to include a plurality of parallel corrugations with the corrugations of one of the plies being substantially identical to the corrugations of the other of the plies. The first and second plies are also peripherally sealed to each other in opposed relation to form the sealed package or envelope with the corrugations of one of the opposed plies in nested relation to the corrugations of the other of the opposed plies. In addition, the sealed package or envelope includes a quantity of the liquid substance and has portions overlaid with respect to each other and separated from each other by intervening spacer means.
