Patent

CA 2741556

Material dispensing systems and methods for make such systems are described. The material dispensing systems employ a collapsible container (18) that is at least partially surrounded by an elastically deformable band (14). The band stretches as the container is filled with a flowable composition, thereby creating potential ener-gy which can then be used to dispense the composition in lieu of a propellant and/or pressurized container.

La présente invention se rapporte à des systèmes de distribution de matière et à des procédés de fabrication de tels systèmes. Les systèmes de distribution de matière emploient un récipient pliant qui est entouré au moins en partie dune bande élastiquement déformable. La bande sétire lorsque le récipient est rempli dune composition liquide, ce qui permet de créer une énergie potentielle qui peut ensuite être utilisée pour distribuer la composition à la place dun récipient de gaz propulseur et/ou sous pression.
