Abstract
A reclosable beverage can end (10) has a circumferential curl (14) centered about a center longitudinal axis (50). A circumferential wall (15) extends downwardly from the curl (14) and inwardly towards the longitudinal axis (50). A center panel (12) is produced from a metallic material and centered about the longitudinal axis (50). The center panel (12) has a public side (34) and an opposing product side (35). A tab (26) is mounted to the public side (34) of the center panel (12). A pour opening (20) is formed by an aperture in the center panel (12) and sealed by the tab (26). The pour opening (20) is at least partially defined by a pour opening curl (22) of the metallic material of the center panel (12).
Claims20
A reclosable beverage can end comprising:
- a circumferential curl centered about a center longitudinal axis of the can end;
- a circumferential wall extending downwardly from the curl and inwardly towards the longitudinal axis;
- a center panel produced from a metallic material and centered about the longitudinal axis comprising a public side and an opposing product side;
- a tab mounted to the public side of the center panel, the tab staked to the center panel by a rivet, wherein the rivet is formed from a material of the center panel and is integral therewith, wherein the tab is rotatable about the rivet;
- and
- a pour opening formed by an aperture in the center panel and sealed by the tab, the pour opening at least partially defined by a pour opening curl of the metallic material of the center panel,
- wherein the pour opening curl extends upwardly from the public side of the center panel, the pour opening curl forming a convex lip and a concave receiver between convex lip and the public side of the center panel, and the tab comprises a tab curl, which matingly engages the pour opening curl, the tab curl having a first tab curl portion extending downwardly and wrapping over the convex lip of the pour opening curl, the first tab curl portion having a first tab curl portion terminal end received within the concave receiver of the pour opening curl, the tab curl further having a second tab curl portion having a second tab curl portion terminal end that is spaced upwardly from the concave receiver of the pour opening.
