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. A tab is formed at a hinge location from the band and extending from the lower edge of the skirt to one or more lines of weakened.

A closure 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;
- 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 weakened section that separates the cylindrical wall and the retention band, wherein the plurality of frangible members extend across the first weakened section and connect the cylindrical wall and the retention band, the first weakened section extending circumferentially with respect to the rotational axis from a first end to a second end that defines a first angle, wherein the first angle is between 10 and 80 degrees;
- a second weakened section that extends circumferentially with respect to the rotational axis, wherein the second weakened section is distinct from the first weakened section, the second weakened section comprising a central portion and lateral portions extending circumferentially away from the central portion, wherein the lateral portions are further from the top panel than the entirety of the first weakened section, and wherein the central portion is further from the top panel than the lateral portions;
- a plurality of weakened section extensions that each extend, from one or more of the central portion and the lateral portions, towards at least one of the top panel and the other extension, the plurality of weakened section extensions comprising a first extension extending towards a first extension end and a second extension extending towards a second extension end, wherein the first extension end and the second extension end define a second angle that is at least 10 degrees and that is less than the first angle;
- a first tether that couples the cylindrical wall to the retention band after the plurality of frangible members are broken, wherein the first tether extends between one of the lateral portions and the first weakened section;
- and
- a second tether that couples the cylindrical wall to the retention band after the plurality of frangible members are broken, wherein the second tether extends between the other of the lateral portions and the first weakened section.
