Abstract

Official abstract text for this publication.

A plastic beer keg includes an outer container and an inner liner. A removable lid is secured over an opening to the container to enclose the liner. In use, the lid can be removed and ice placed in the container directly on the liner, ice flows into gaps between the liner and the container to provide rapid cooling of the content of the liner.

First claim

Opening claim text (preview).

What is claimed is: 1. A plastic beer keg including: a container having a base and a wall extending upward from a periphery of the base; and a liner within the container, wherein a spacing between the liner and the container varies around a periphery of the liner, wherein the periphery is defined generally parallel to the base, to a portion of increased spacing defining at least one vertical gap between the liner and the container, wherein the vertical gap is elongated vertically upward relative to the liner and the container, wherein the base is generally round and wherein the wall includes at least one portion of reduced diameter defining at least one recess below a portion of larger diameter defining a handle on an exterior of the container above the recess and wherein the at least one portion of reduced diameter contacts the liner to define the at least one vertical gap on an interior of the container adjacent the at least one portion of reduced diameter. 2. The plastic beer keg of claim 1 further including a valve assembly secured to a mouth of the liner. 3. The plastic beer keg of claim 1 wherein the container includes at least one corrugation formed in the wall, the at least one corrugation forming the at least one vertical gap. 4. The plastic beer keg of claim 1 wherein the container has a cross section parallel to the base having at least one corner, and wherein the at least one gap is defined in the at least one corner. 5. The plastic beer keg of claim 4 wherein a cross section of the container parallel to the base is generally rectangular. 6. The plastic beer keg of claim 1 further including a removable lid secured to an upper edge of the wall, enclosing the liner. 7. The plastic beer keg of claim 1 wherein the liner is PET. 8. The plastic beer keg of claim 1 further including a handle pivotably secured to the wall. 9. The plastic beer keg of claim 1 wherein the liner includes a plurality of feet formed at a lower end thereof. 10. The plastic beer keg of claim 1 wherein the wall of the container is tapered such that the container is nestable with a similar container when empty. 11. The plastic beer keg of claim 10 wherein the wall includes a plurality of recesses formed in an exterior thereof, each of the recesses defining a stepped-in portion protruding into an interior of the container, the liner fitting snugly between the stepped-in portions of the wall, the at least one vertical gap includes a plurality of vertical gaps defined adjacent the stepped-in portions, at least two of the plurality of recesses having handles defined at upper ends thereof by portions of the wall having a larger diameter. 12. The plastic beer keg of claim 1 wherein the liner includes at least one vertical recessed portion defining the at least one vertical gap. 13. The plastic beer keg of claim 1 wherein the liner includes a plurality of alternating portions of increased and decreased diameter defining the at least one vertical gap. 14. A plastic beer keg including: a container having a base and a wall extending upward from a periphery of the base, the wall of the container being tapered such that the container is nestable with a similar container when empty, wherein the base is generally round and wherein the wall includes at least one recess below a portion of larger diameter defining a handle on an exterior of the container and wherein the at least one recess forms at least one vertical gap on an interior of the container; a liner within the container, the liner including a mouth opening into an interior of the liner; a valve secured to the mouth; and a spear extending from the valve to a lower end of the interior of the liner. 15. The plastic beer keg of claim 14 wherein the container includes at least one corrugation formed in the wall, the at least one corrugation elongated vertically upward relative to the container and forming at least one vertical gap between the wall and the liner, the at least one vertical gap extending from a mouth of the container to the base of the container. 16. The plastic beer keg of claim 14 wherein the container has a cross section generally parallel to the base having at least one corner. 17. The plastic beer keg of claim 14 further including a removable lid secured to an upper edge of the wall, enclosing the liner. 18. The plastic beer keg of claim 14 wherein the liner is PET. 19. The plastic beer keg of claim 14 wherein the liner is tapered to match the wall of the container. 20. A plastic beer keg including: a container having a base and a wall extending upward from a periphery of the base, wherein the base is generally round and wherein the wall includes at least one recess below a portion of larger diameter defining a handle on an exterior of the container and wherein the at least one recess forms at least one vertical gap on an interior of the container; a liner within the container, the liner including an opening into an interior of the liner; a spear extending from a valve to a lower end of the interior of the liner; and a lid removably secured to the container, thereby enclosing the container, wherein the lid is removable and re-securable to an upper edge of the wall of the container. 21. The plastic beer keg of claim 20 further including at least one vertical gap between the liner and the container, the at least one vertical gap extending from a mouth of the container to the base of the container. 22. The plastic beer keg of claim 20 wherein the container has a cross section generally parallel to the base having at least one corner. 23. The plastic beer keg of claim 20 wherein the liner is PET. 24. The plastic beer keg of claim 14 wherein the wall of the container includes a radially outward projection, wherein the container is nestable up to the radially outward projection within the similar container when empty. 25. The plastic beer keg of claim 14 wherein the wall of the container is tapered down to the base. 26. The plastic beer keg of claim 14 wherein a tapered portion of the wall is nestable within the tapered portion of the wall of the similar container when empty. 27. The plastic beer keg of claim 14 wherein the container and the liner are plastic. 28. The plastic beer keg of claim 20 wherein the container and the lid are plastic. 29. The plastic beer keg of claim 28 wherein the lid snap-fits over an uppermost edge of the wall of the container. 30. The plastic beer keg of claim 29 wherein the wall of the container tapers from the upper edge down to the base such that the container is nestable with an identical container when empty.
