The invention claimed is: 1. A method for forming a threaded laminated cup for use in sealing a container, comprising: forming a pedestal of a cup, wherein said forming comprises providing the pedestal with a first plastic laminated layer and second metal layer, an interior cavity having an inner surface, and a top portion that has a larger diameter than a bottom portion; inserting a non-threaded arbor into the interior cavity to engage the inner surface of the bottom portion; and engaging the second layer with a threading tool, wherein said engaging comprises deforming the metal of the second layer into threads, and compressing the plastic laminate of the first layer between the threads and the non-threaded arbor such that the second layer maintains a generally uniform thickness along the threads. 2. The method of claim 1, wherein the inner surface along the top and bottom portions is non-threaded after said engaging step. 3. The method of claim 1, wherein the first layer is polypropylene. 4. The method of claim 1, wherein the second layer is steel. 5. The method of claim 1, wherein prior to said inserting step, the first layer has a thickness within the range of 0.0070 inches to 0.0090 inches. 6. The method of claim 1, wherein prior to said inserting step, the second layer has a thickness within the range of 0.0090 inches to 0.0140 inches. 7. The method of claim 1, wherein prior to said inserting step, the first and second layers combined together have a thickness within the range of 0.0160 inches to 0.0230 inches. 8. The method of claim 1, wherein prior to said inserting step, the bottom portion has an inner diameter that is approximately equal to an inner diameter of the pedestal at the threads after said engaging step. 9. The method of claim 1, wherein the pedestal has a side wall and prior to said inserting step, the side wall has generally the same thickness at the bottom portion and the top portion. 10. The method of claim 1, wherein said pedestal has a top wall, wherein during said inserting step, the non-threaded arbor extends to, and engages, the first layer along the top wall. 11. The method of claim 1, wherein the threading tool engages the second layer of the pedestal by being moved about the second layer to thread the second layer. 12. The method of claim 1, wherein, during said engaging step, the first layer is compressed within gaps formed inside the threads of the second layer and allows the second layer to be bent by the threading tool. 13. The method of claim 1, wherein, after said engaging step, the top and bottom portions have a generally uniform outer diameter at the threads. 14. The method of claim 1, wherein, after said engaging step, the top and bottom portions have a generally uniform inner diameter along the inner surface. 15. A laminated cup for use in sealing a container, comprising: a base having a pedestal and an outer wall extending therefrom, said pedestal defining an interior cavity with an inner surface and having an inner first layer and an outer second layer and being formed of a plastic laminated metal material such that said first layer is plastic laminate and said second layer is metal, said second layer having an inner side disposed along said first layer, wherein said second layer has threads and has a generally uniform thickness at said threads, said threads defining gaps therebetween along said inner side of said second layer and said laminate of said first layer filling said gaps such that said inner surface of said pedestal is non-threaded. 16. The laminated cup of claim 15, wherein said first layer is polypropylene. 17. The laminated cup of claim 15, wherein said second layer is steel. 18. The laminated cup of claim 15, wherein said cup includes a peripheral rim intergrally connected to said base by an outer wall, said outer wall having a skirt, said cup receiving said container between said outer wall and said skirt such that said cup is sealable about said container. 19. The laminated cup of claim 15, wherein said threads are configured such that said pedestal may be threadably engaged to a can tap having corresponding threads. 20. The laminated cup of claim 15, wherein said pedestal has a generally uniform outer diameter at said threads. 21. The laminated cup of claim 15, wherein said pedestal has a generally uniform inner diameter along said inner surface. 22. A method for forming a threaded laminated cup for use in sealing a container, comprising: forming a pedestal of a cup, wherein said forming comprises providing the pedestal with a first plastic laminated layer and second metal layer, an interior cavity having an inner surface and a top wall, and a top portion that has a larger diameter than a bottom portion; inserting a non-threaded arbor into the interior cavity to engage the first layer along the top wall and the inner surface at the bottom portion; and engaging the second layer with a threading tool, wherein said engaging comprises moving the threading tool about the second layer to deform the metal of the second layer into threads, and compressing the plastic laminate of the first layer into gaps formed between the threads and the non-threaded arbor such that the first layer allows the second layer to be deformed by the threading tool and maintain a generally uniform thickness along the threads while the inner surface along the top and bottom portions remains non-threaded. 23. A method for forming a threaded cup for use in sealing a container, comprising: forming a pedestal of a cup, wherein said forming comprises providing the pedestal with an inner surface and an outer surface, a metal layer, an interior cavity and a top portion that has a larger diameter than a bottom portion; inserting a non-threaded arbor into the interior cavity to engage the inner surface along the bottom portion; and engaging the outer surface with a threading tool, wherein said engaging comprises displacing the metal layer along the top portion towards the non-threaded arbor and deforming the metal layer into threads, such that the metal layer maintains a generally uniform wall thickness along the threads. 24. The method of claim 23, wherein the metal layer is steel. 25. The method of claim 23, wherein the metal layer has a thickness within the range of 0.0090 inches to 0.0180 inches. 26. The method of claim 23, wherein prior to said inserting step, the bottom portion has an inner diameter that is approximately equal to an inner diameter of the pedestal at the threads after said engaging step. 27. The method of claim 23, wherein the pedestal has a side wall and prior to said inserting step, the side wall has generally the same thickness at the bottom portion and the top portion. 28. The method of claim 23, wherein the threading tool engages the metal layer of the pedestal by being moved about the outer surface of the metal layer to thread the metal layer. 29. The method of claim 23, wherein, after said engaging step, the top and bottom portions have a generally uniform outer diameter at the threads.
