The end member of claim 1 wherein said fluid is cured to become at least a semisolid. 3. The end member of claim 2 wherein said at least a semisolid substantially seals said opening in said fold. 4. The end member of claim 1 wherein said fluid enters said cavity through said opening. 5. The end member of claim 4 wherein said cavity is substantially filled with said fluid. 6. The end member of claim 5 wherein said fluid is cured to become at least a semisolid. 7. The end member of claim 6 wherein said at least a semisolid substantially seals said opening. 8. The end member of claim 1 wherein the fluid is within said opening. 9. An end member for a beverage container, the end member comprising: a curl at least substantially defining a perimeter of the can end; a chuck wall extending downwardly and radially inwardly from the curl; a central panel wall centered about a longitudinal axis, the central panel wall having a product side and a public side, the public side having a means for opening a frangible panel segment; a fold joining said chuck wall with said central panel wall, said fold including first and second circumferential legs joined by a circumferential arcuate segment, said fold further including an opening located along a peripheral edge of the central panel; and a polymeric insert located within said opening, wherein said fold includes a cavity between said first and second legs, at least a portion of said polymeric insert located within said cavity and substantially sealing said opening. 10. The end member of claim 9 wherein said polymeric insert is produced from a fluid cured within said cavity. 11. The end member of claim 10 wherein said fluid is injected into said cavity. 12. The end member of claim 9 wherein a portion of said fold is located radially outwardly of said chuck wall. 13. An end member for a beverage container, the end member having a curl at least substantially defining a perimeter of the can end, a chuck wall extending downwardly and radially inwardly from the curl, a central panel wall centered about a longitudinal axis, the central panel wall having a product side and a public side, the public side having a means for opening a frangible panel segment, the end member comprising: a fold joining said chuck wall with the central panel wall, said fold including first and second circumferential legs joined at respective first ends by a circumferential arcuate segment, and said fold having a radially outermost portion located radially outwardly from the chuck wall; and an insert substantially sealing said fold. 14. The end member of claim 13 wherein said insert is a cured fluid located within said fold. 15. The end member of claim 14 wherein said cured fluid is a polymeric material. 16. The end member of claim 13 wherein said first and second circumferential legs have second ends opposite said first ends wherein a spacing between said second ends is less than a spacing between said first ends, and a cavity is located between said first and second legs, said cavity having an opening located between said second ends wherein said insert is located within said opening.
