Abstract
A can end has a curl extending circumferentially about a longitudinal axis. A circumferential wall extends downwardly. A strengthening member is joined to lower segment of the circumferential wall. A center panel extends radially inwardly from the circumferential strengthening member. A rivet attaches a tab to the center panel. A cover is attached to the tab and is rotation therewith. A frangible score in the center panel is breakable to form a pour opening in the center panel. The cover is rotatable to overlay the pour opening and effectively reclose the pour opening in a reclosed condition of the can end.
Claims20
A can end (10) for enclosing a container body comprising:
- a curl (14) extending circumferentially about a longitudinal axis (50);
- a circumferential wall (15) extending downwardly from a radially inner portion of the curl (14);
- a circumferential strengthening member (16) joined to lower segment of the circumferential wall (15)
- a center panel (12) about which the circumferential strengthening member (16) extends having a public side (32) opposite a product side (34), the center panel (12) comprising;
- a peripheral edge defining a radially outer perimeter of the center panel (12);
- a tear panel (22) spaced radially inwardly from the peripheral edge, the tear panel (22) defined by a frangible score (24) in the public side (32) and non-frangible hinge segment located between terminal ends of the frangible score (24);
- and
- a rivet (38);
- a tab (28) is attached to the center panel (12) by the rivet (38), wherein the tab (28) is configured to rotate about the rivet (38), the tab (28) comprising:
- a lift end (40) opposite a nose portion (42) overlaying the tear panel (22) in a frangible score (24) breaking position;
- a rivet island (39) having a rivet aperture through which the rivet (38) passes to attach the tab (28) to the center panel (12);
- a void region partially surrounding the rivet island (39) having a first leg (39a) extending along a first side of the rivet island (39) and a second leg (39b) extending along a second side of the rivet island (39);
- and
- a tab hinge extending between respective terminal ends of the first and second legs (39a,39b) of the void region;
- a cover (60) is attached to the tab (28) and is rotational therewith,
- wherein the frangible score (24) is breakable to form a pour opening (27) in the center panel (12), and the cover (60) is rotatable to overlay the pour opening (27) and effectively reclose the pour opening (27) in a reclosed condition of the can end (10),
- wherein the center panel (12) comprises a bead near the rivet (38) and opposite the tear panel (22) in relation to the rivet (38), wherein the bead is located beneath the rivet island (39) of the tab (28) when the can end (10) is in the reclosed condition,
- wherein the bead near the rivet (38) is a down-bead which receives a portion of one of the rivet island (39) or the cover (60) when the can end (10) is in the reclosed condition.
