Title: Pressurized piston pusher
IPC: C01F11/00
Filed: 2002-03-21
Abstract: 1. A pressurized piston pusher comprising: a housing with scoring at one or more predetermined locations and with two ends that are sealed to prevent leakage of viscous fluids contained within it and maintains a pressurized air enclosure; a seal comprising of a viscous substance inserted in the housing separating the viscous fluid from the air thereby creating an pressurized air enclosure; a pressurized piston pusher comprising of a piston with a cross-sectional profile that is approximately that of the internal cross-sectional profile of the housing; wherein the pressurized air enclosure will urge the pressurized piston pusher to force the viscous fluid out of the container when the container is opened at the scoring at one or more predetermined locations. 2. A pressurized piston pusher as in claim 1, wherein comprises two pistons inserted at either end of the housing separating the fluid contained in the housing from pressurized air enclosures at either end of the housing. 3. A pressurized piston pusher as in claim 1 or 2, wherein the housing has an internal and an external surface and wherein the internal surface has one or more protrusion near the scoring at one or more predetermined locations to retain the pressurized piston pusher after the viscous fluids are forced out of the housing. 4. A pressurized piston pusher as in claim 1, wherein the housing has an internal and an external surface and wherein the external surface has one or more indentation that deforms the internal surface near the scoring at one or more predetermined locations to retain the pressurized piston pusher after the viscous fluids are forced out of the housing. 5. A pressurized piston pusher comprising: a housing with scoring at one or more predetermined locations and with two ends that are sealed to prevent leakage of viscous fluids contained within it and maintains a pressurized air enclosure; a seal comprising of a viscous substance inserted in the housing separating the viscous fluid from the; air thereby creating an pressurized air enclosure; a piston made with rigid material with a cross-sectional profile that is slightly smaller than the of the internal cross-sectional profile of the housing; wherein the pressurized air enclosure will urge the pressurized piston pusher to force the viscous fluid out of the container when the container is opened at the scoring at one or more predetermined locations. 6. A pressurized piston pusher as in claim 5, wherein comprises two pistons inserted at either end of the housing separating the fluid contained in the housing; from pressurized air enclosures at either end of the housing. 7. A pressurized piston pusher as in claim 5 or 6, wherein the housing has an internal and an external surface and wherein the internal surface has one or more protrusion near the scoring at one or more predetermined locations to retain the pressurized piston pusher after the viscous fluids are forced out of the hosing. 8. A pressurized piston pusher as in claim 5 or 6, wherein the housing has an internal and an external surface and wherein the external surface has one or more indentation that deforms the internal surface near the scoring at one or more predetermined locations to retain the pressurized piston pusher after the viscous fluids are forced out of the housing.
