A tab is provided for a can end. The can end includes an end panel and a scoreline defining a tear panel in the end panel for providing an opening in the can end. The tab includes a body having first and second opposing ends, a nose portion located at or about the first end, a lift portion located at or about the second end, and a rivet receiving portion disposed proximate the nose portion. The rivet receiving portion includes a rivet hole. A first rivet extends outwardly from the end panel and fastens the rivet receiving portion of the tab to the can end. A second rivet extends outwardly from the end panel to cooperate with a portion of the body proximate the lift portion.

1. A tab for a can end, the can end comprising an end panel, a first rivet, a second rivet, and a scoreline defining a tear panel in the end panel for providing an opening in the can end, the tab comprising: a body including a first end, a second end disposed opposite and distal from the first end,
1. A tab for a can end, the can end comprising an end panel, a first rivet, a second rivet, and a scoreline defining a tear panel in the end panel for providing an opening in the can end, the tab comprising: a body including a first end, a second end disposed opposite and distal from the first end, and a top surface disposed in a first plane;a nose portion located at or about the first end of the tab;a lift portion located at or about the second end of the tab, the lift portion being structured to pivot about the second rivet;a rivet receiving portion disposed proximate the nose portion, the rivet receiving portion including a rivet hole;a recessed panel located proximate the lift portion and being disposed in a second plane parallel to the first plane, the recessed panel including a rivet aperture, the second rivet being structured to extend through the rivet aperture and be fastened to the recessed panel; anda middle portion separating the recessed panel from the rivet receiving portion;wherein the first rivet is structured to extend outwardly from the end panel and fasten the rivet receiving portion of the tab to the can end;wherein the second rivet is structured to extend outwardly from the end panel;wherein when the lift portion is lifted, the second plane of said recessed panel remains parallel to the first plane of the top surface of the body;wherein the recessed panel extends from proximate the second end toward the rivet receiving portion;wherein the second rivet is structured to be disposed in the recessed panel;wherein the middle portion comprises a top portion, a first downwardly extending portion, and a second downwardly extending portion;wherein the top portion is generally coplanar with the top surface of the tab body;wherein the first downwardly extending portion extends from the top portion to the recessed panel; andwherein the second downwardly extending portion extends from the top portion toward the rivet receiving portion. 2. The tab of claim 1 wherein the end panel further comprises an additional scoreline proximate the second rivet; and wherein when the lift portion pivots about the second rivet, the additional scoreline at least partially severs to vent the can end. 3. The tab of claim 2 wherein the additional scoreline extends circumferentially around the second rivet. 4. The tab of claim 3 wherein, when the lift portion is lifted, the lift portion is structured to detach the second rivet from the end panel, thereby creating a vent opening in the can end. 5. The tab of claim 1 wherein the body further comprises a longitudinal axis extending through the center of the tab between the first end and the second end, and a plurality of slots; wherein the slots are disposed between the nose portion and the lift portion on opposing sides of the tab; wherein the slots combine to form a fulcrum that extends generally transverse to the longitudinal axis; and wherein the fulcrum enables the lift portion to pivot upwards and downwards in relation to the nose portion. 6. The tab of claim 1 wherein the tab comprises a single unitary piece of metal. 7. A combination of a tab with a can end affixed to the tab, the can end being selected from the group consisting of beer can ends, beverage can ends and food can ends, the can end comprising an end panel, a first rivet, a second rivet, and a scoreline defining a tear panel in the end panel for providing an opening in the can end, the tab comprising: a body including a first end, a second end disposed opposite and distal from the first end, and a top surface disposed in a first plane;a nose portion located at or about the first end of the tab;a lift portion located at or about the second end of the tab, the lift portion being structured to pivot about the second rivet;a rivet receiving portion disposed proximate the nose portion, the rivet receiving portion including a rivet hole;a recessed panel located proximate the lift portion and being disposed in a second plane parallel to the first plane, the recessed panel including a rivet aperture, the second rivet being structured to extend through the rivet aperture and be fastened to the recessed panel; anda middle portion separating the recessed panel from the rivet receiving portion;wherein the first rivet is structured to extend outwardly from the end panel and fasten the rivet receiving portion of the tab to the can end;wherein the second rivet is structured to extend outwardly from the end panel;wherein when the lift portion is lifted, the second plane of said recessed panel remains parallel to the first plane of the top surface of the body;wherein the recessed panel extends from proximate the second end toward the rivet receiving portion;wherein the second rivet is structured to be disposed in the recessed panel;wherein the middle portion comprises a top portion, a first downwardly extending portion, and a second downwardly extending portion;wherein the top portion is generally coplanar with the top surface of the tab body;wherein the first downwardly extending portion extends from the top portion to the recessed panel; andwherein the second downwardly extending portion extends from the top portion toward the rivet receiving portion. 8. The tab of claim 1 wherein the lift portion has a top surface disposed in a third plane; and wherein before the lift portion is lifted, the third plane is coplanar with the first plane. 9. The tab of claim 1 wherein a portion of the nose portion and a portion of the lift portion have curled edges. 10. The tab of claim 5 wherein each of the plurality of slots is disposed between the second rivet and the second end; and wherein the fulcrum is spaced from the second rivet. 11. The tab of claim 10 wherein the opposing sides comprise a first side and a second side opposite the first side, wherein the plurality of slots comprises a first slot disposed on the first side and a second slot disposed on the second side, and wherein the recessed panel extends from proximate the first slot to proximate the second slot. 12. The tab of claim 1 wherein the body is devoid of a finger hole. 13. The combination of claim 7 wherein the can end further comprises an additional scoreline in the end panel, and wherein the additional scoreline extends circumferentially around the second rivet. 14. The combination of claim 7 wherein when the lift portion is lifted, the tear panel is structured to remain attached to the end panel. 15. The combination of claim 7 wherein the entire tear panel is substantially disposed on a first side of the end panel.
