1. 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 to a bottom edge of the cylindrical wall;
an inner surface of the cylindrical wall facing towards the rotational axis;
a first tether that extends from the cylindrical wall;
a second tether that extends from the cylindrical wall;
a retention band pivotally coupled to the cylindrical wall by the first tether and the second tether, the retention band attached to the bottom edge 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; and
a second line of weakness at least a portion of which is below the first line of weakness, the second line of weakness including a tab portion and first lateral sections that extend circumferentially away from the tab portion, wherein the tab portion define a first height from the top panel and the first lateral sections define a second height from the top panel that is less than the first height, and wherein the tab portion includes second lateral sections that extend circumferentially away from the first lateral sections and that define a third height from the top panel greater than the second height, and wherein the third height is equal to the first height, and wherein the first lateral sections are between the first end and the second end of the first line of weakness, wherein the tab portion defines an angle between 110 degrees and 160 degrees with respect to a connecting portion of the second line of weakness that extends from the tab portion, and wherein no portion of the first line of weakness is further from the top panel than the second line of weakness;
wherein the first tether is defined between the second line of weakness and the first end of the first line of weakness, and the second tether is defined between the second line of weakness and the second end of the first line of weakness.
