Abstract

A can end and a tab configured to couple to the can end and a related method are provided. The can end is continuous. The tab is configured to couple to the can end with a post, which couples the tab to the can end without passing through the can end.

First claim

What is claimed is:

1. A can including a sidewall, the can providing an interior compartment containing a product, the can comprising:
a continuous can end including a periphery and a well located radially inwardly from the periphery, the well including a sidewall, including a non-circular portion, and a bottom wall, the can end coupled to the sidewall of the can sealing the can;
a tab defined by a body extending from a first end to a second end, the body lying along a first plane that is generally parallel to a second plane along which the can end lies; and
a post extending from the tab at a location between the first end and the second end of the tab, the post having a non-circular cross-section, the post being located in the well of the can end coupling the tab to the can end, wherein the non-circular portion of the sidewall of the well and the non-circular cross-section of the post inhibit rotation of the tab relative to the can end;
wherein the post is attached to the tab such that movement of the first end of the tab in an upward direction relative to an upper surface of the can end is configured to cause the tab to pivot about the post and result in the movement of the second end of the tab in a downward direction relative to the upper surface of the can end.

2. The can of claim 1 , wherein the first end of the tab includes a ring portion extending along the first plane and the post extends in a direction non-perpendicular to the first plane.

3. The can of claim 2 , wherein an aperture is defined between an upper surface and a lower surface of the tab at a location between the ring portion of the first end and the second end of the tab.

4. The can of claim 3 , wherein the post extends through the aperture.

5. The can of claim 2 , wherein the post extends from a first end to a second end surrounding an axis and wherein the axis and the plane form an angle therebetween of more than 90 degrees.

6. The can of claim 5 , wherein the angle is between 100 degrees and 110 degrees.

7. The can of claim 1 , wherein the post includes a retaining feature configured to deter removal of the post from the well.

8. The can of claim 7 , wherein the retaining feature includes a radially outwardly projecting ridge.

9. A can including a sidewall, the can providing an interior compartment containing a product, the can comprising:
a continuous can end including a periphery and a well located radially inwardly from the periphery, the well including a sidewall, including a non-circular portion, and a bottom wall, the can end coupled to the sidewall of the can sealing the can; and
a tab with a post extending from the tab, the post having a non-circular cross-section, the post being located in the well of the can end coupling the tab to the can end, wherein the non-circular portion of the sidewall of the well and the non-circular cross-section of the post inhibit rotation of the tab relative to the can end;
wherein the tab includes a ring portion and a second portion configured to rupture the can end, wherein the can end includes a depression located under at least a portion of the ring portion, and wherein the post does not extend through the can end.

10. The can of claim 9 , wherein the ring portion of the tab extends along a plane and the post extends in a direction non-perpendicular to the plane.

11. The can of claim 10 , wherein the post extends from a first end to a second end surrounding an axis and wherein the axis and the plane form an angle therebetween of more than 90 degrees.

12. The can of claim 11 , wherein the angle is between 100 degrees and 110 degrees.

13. The can of claim 9 , wherein the post includes a retaining feature configured to deter removal of the post from the well.

14. The can of claim 13 , wherein the retaining feature includes a radially outwardly projecting ridge.

15. A can end comprising:
a continuous can end surface including a periphery and a well located radially inwardly from the periphery, the well including a sidewall, including a non-circular portion, and a bottom wall, the can end being configured to be coupled to a sidewall of a can so as to seal the can;
a tab with a post extending from the tab, the post having a non-circular cross-section, the post being located in the well of the can end coupling the tab to the can end, wherein the non-circular portion of the sidewall of the well and the non-circular cross-section of the post inhibit rotation of the tab relative to the can end;
wherein the tab includes a ring portion and a second portion configured to rupture the can end, wherein the can end surface includes a depression located under at least a portion of the ring portion, and wherein the post does not extend through the can end.

16. The can end of claim 15 , wherein the ring portion of the tab extends along a plane and the post extends in a direction non-perpendicular to the plane.

17. The can end of claim 16 , wherein the post extends from a first end to a second end surrounding an axis and wherein the axis and the plane form an angle therebetween of more than 90 degrees.

18. The can end of claim 17 , wherein the angle is between 100 degrees and 110 degrees.

19. The can end of claim 15 , wherein the post includes a retaining feature configured to deter removal of the post from the well.

20. The can end of claim 19 , wherein the retaining feature includes a radially outwardly projecting ridge.
