A system and method for injecting pressurizing fluid into a filled and sealed container is provided. The container is filled with a product and is then sealed with a closure. A pressurizing fluid is injected through the closure into the container cavity after sealing and filling.

대표청구항 ▼

1. A fluid injection method for pressurizing a filled and sealed food or beverage container comprising: providing a container having an opening and cavity;filling the container cavity through the opening with a food or beverage product;providing an injection molded thermoplastic closure, the closure including: a top panel;a skirt extending downward away from the top panel; anda thermoplastic elastorner liner coupled to a lower surface of the top panel, the liner comprising: a central portion having a first thickness and an outer portion located radially outward of the central portion and having a second thickness;wherein the first thickness is between 0.010 and 0.110 inches and the first thickness is more than twice the second thickness; anda sealing rib extending downwardly relative to the outer portion and configured to contact an inner rim of the container;sealing the container opening with the closure, the container having a first internal pressure following sealing of the container with the closure;after filling and sealing the container, inserting a nozzle into the cavity of the container by piercing through the top panel and the central portion of the thermoplastic elastomer liner;injecting a pressurizing fluid through the nozzle into the container cavity after sealing and filling;controlling the injection of the pressurizing fluid with a valve and control, system; andremoving the nozzle from the thermoplastic elastomer liner, wherein the central portion of the thermoplastic elastomer liner self-seals forming a hermetic seal after withdrawal of the nozzle, wherein the container has a second internal pressure after injection of the pressurized fluid and removal of the nozzle, wherein the second internal pressure is greater than the first internal pressure. 2. The fluid injection method of claim 1 wherein the pressurizing fluid is a sterile inert gas. 3. The fluid injection method of claim 1 wherein the pressurizing fluid is nitrogen gas. 4. The fluid injection method of claim 1 further comprising inspecting the injection nozzle for defects following withdrawal of the injection nozzle. 5. The fluid injection method of claim 1 further comprising inspecting the closure and container for defects following withdrawal of the injection nozzle. 6. The fluid injection method of claim 1 further comprising sterilizing the closure following sealing and prior to injection of the pressurized fluid. 7. The fluid injection method of claim 1, wherein the valve is a solenoid actuated check valve. 8. A fluid injection method for pressurizing a filled and sealed food or beverage container comprising: providing a container having an opening and cavity;filling the container cavity through the opening with a food or beverage product;providing an injection molded thermoplastic closure, the closure including: a top panel having a thickness;a skirt extending downward from the top panel; anda thermoplastic elastomer liner coupled to a lower surface of the top panel, the liner comprising: a central portion having a thickness;an outer portion located radially outward of the central portion and having a thickness that is less than the thickness of the central portion;wherein the thickness of the central portion is between 0,010 and 0.060 inches and is substantially the same as the thickness of the top panel; anda sealing rib extending downwardly relative to the outer portion and configured to contact an inner rim of the container;scaling the container opening with the closure, the container having a first internal pressure following sealing of the container with the closure;after filling and sealing the container, inserting a nozzle into the cavity of the container by piercing through the top panel and the central portion of the thermoplastic elastomer liner;injecting a pressurizing fluid through the nozzle into the container cavity after sealing and filling;controlling the injection of the pressurizing fluid with a valve and control system; andremoving the nozzle from the thermoplastic elastomer liner, wherein the central portion of the thermoplastic elastomer liner self-seals forming a hermetic seal after withdrawal of the nozzle, wherein the container has a second internal pressure after injection of the pressured fluid and removal of the nozzle, wherein the second internal pressure is greater than the first internal pressure. 9. The fluid injection method of claim 8 wherein the pressurizing fluid is a sterile inert gas. 10. The fluid injection method of claim 8 wherein the pressurizing fluid is nitrogen gas. 11. The fluid injection method of claim 8 further comprising inspecting the injection nozzle for defects following withdrawal of the injection nozzle. 12. The fluid injection method of claim 8 further comprising inspecting the closure and container for defects following withdrawal of the injection nozzle. 13. The fluid injection method of claim 8 further comprising sterilizing the closure following sealing and prior to injection of the pressurized fluid. 14. The fluid injection method of claim 8, wherein the valve is a solenoid actuated check valve. 15. A fluid injection method for pressurizing a filled and sealed food or beverage container comprising: providing a container having an opening and cavity;filling the container cavity through the opening with a food or beverage product;providing an injection molded thermoplastic closure, the closure including: a top panel having a thinned central portion;a skirt extending downward from the top panel; anda thermoplastic elastomer liner coupled to a lower surface of the top panel, the liner comprising: a central portion located within the thinned central portion of the top panel and having a thickness between 0.010 and 0.110 inches;an outer portion located radially outward of the liner central portion and having a thickness that is less than the thickness of the liner central portion; anda sealing rib extending downwardly relative to the outer portion and configured to contact an inner rim of the container;scaling the container opening with the closure, the container having a first internal pressure following sealing of the container with the closure;after filling and sealing the container, inserting a nozzle into the cavity of the container by piercing through the top panel and the central portion of the thermoplastic elastomer liner;injecting a pressurizing fluid through the nozzle into the container cavity after sealing and filling;controlling the injection of the pressurizing fluid with a valve and control system; and removing the nozzle from the thermoplastic elastomer liner, wherein the central portion of the thermoplastic elastomer liner self-seals forming a hermetic seal after withdrawal of the nozzle, wherein the container has a second internal pressure after injection of the pressurized fluid and removal of the nozzle, wherein the second internal pressure is greater than the first internal pressure. 16. The fluid injection method of claim 15 wherein the pressurizing fluid is a sterile inert gas. 17. The fluid injection method of claim 15 wherein the pressurizing fluid is nitrogen gas. 18. The fluid injection method of claim 15 further comprising inspecting the injection nozzle for defects following withdrawal of the injection nozzle. 19. The fluid injection method of claim 15 further comprising inspecting the closure and container for defects following withdrawal of the injection nozzle. 20. The fluid injection method of claim 15 further comprising sterilizing the closure following sealing and prior to injection of the pressurized fluid.
