MATERIAL DISPENSING SYSTEM AND METHOD FOR MAKING SAME

摘要

Material dispensing systems and methods for make such systems are described. The material dispensing systems employ a collapsible container that is at least partially surrounded by an elastically deformable band. The band stretches as the container is filled with a flowable composition, thereby creating potential energy which can then be used to dispense the composition in lieu of a propellant and/or pressurized container.
