Abstract
A closure includes a cap having a top wall and a skirt perpendicular to the top wall and extending downwardly from the top wall to a lower edge. The skirt includes an inner surface having a sealing formation. A band is concentric with and attached to the lower edge of the skirt by a plurality of frangible members. The band remains coupled to the body of the closure even after being removed from a container.
Claims20
A closure for a container comprising:
- a top panel including an upper surface and a lower surface;
- a rotational axis about which the top panel is centered;
- a cylindrical wall extending from the lower surface of the top panel;
- an inner surface of the cylindrical wall facing towards the rotational axis;
- a retention band pivotally coupled to the cylindrical wall, the retention band attached to the cylindrical wall by a plurality of frangible members, the frangible members providing a visual indication, when broken, that the closure has been opened;
- a first line of weakness that separates the cylindrical wall and the retention band, wherein the plurality of frangible members extend across the first line of weakness and connect the cylindrical wall and the retention band, the first line of weakness extending circumferentially around the closure from a first end to a second end;
- a second line of weakness that extends circumferentially around the closure;
- a hinge defined between the first end and the second end of the first line of weakness, wherein the cylindrical wall pivots with respect to the retention band around the hinge;
- a first tether that maintains a coupling between the cylindrical wall and the retention band when the closure is opened;
- a second tether that maintains a coupling between the cylindrical wall and the retention band when the closure is opened;
- and
- an interference band that extends from the retention band inwardly towards the rotational axis and upwardly towards the top panel, the interference band extends a first length from the retention band at a first location beneath the hinge, the interference band comprising a second location opposite the first location with respect to the rotational axis, a third location circumferentially halfway between the first location and the second location, and a fourth location circumferentially halfway between the first location and the third location, wherein the interference band extends a second length at the third location, and a third length at the fourth location, wherein the second length is greater than the first length, and wherein the difference between the first length and the third length is the same as the difference between the second length and the third length.
