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 pivotally connected to an upper portion of the closure.
Claims20
A closure comprising:
- a top panel comprising 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 lower edge of the cylindrical wall, an inner surface of the cylindrical wall facing towards the rotational axis;
- a retention band pivotally coupled to the top panel and the cylindrical wall;
- a line of weakness that separates the cylindrical wall and the retention band, the line of weakness extending circumferentially around the closure from a first end to a second end;
- a plurality of frangible members extending across the line of weakness to couple the cylindrical wall and the retention band;
- a hinge located between the first end and the second end of the line of weakness, the hinge pivotally coupling the retention band and the top panel;
- and
- a tab pivotally coupled to the top panel opposite the hinge with respect to the rotational axis, the tab attached to the retention band by a tab frangible member that is distinct from the plurality of frangible members, the tab frangible member providing a visual indication, when broken, that the tab has been opened.

A closure for coupling to a container neck, the closure comprising:
- a top panel comprising 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 lower edge of the cylindrical wall, an inner surface of the cylindrical wall facing towards the rotational axis;
- a retention band pivotally coupled to the top panel and the cylindrical wall;
- a line of weakness that separates the cylindrical wall and the retention band, the line of weakness extending circumferentially around the closure from a first end to a second end;
- a plurality of frangible members extending across the line of weakness to couple the cylindrical wall and the retention band;
- a hinge located between the first end and the second end of the line of weakness, the hinge pivotally coupling the retention band and the top panel;
- and
- a tab pivotally coupled to the top panel opposite the hinge with respect to the rotational axis, the tab comprising a detent that projects inwardly towards the rotational axis and that interfaces against an extension extending from a container neck of a container away from the rotational axis.

A closure comprising:
- a top panel comprising 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 lower edge of the cylindrical wall, an inner surface of the cylindrical wall facing towards the rotational axis;
- a retention band pivotally coupled to the top panel and the cylindrical wall;
- a line of weakness that separates the cylindrical wall and the retention band, the line of weakness extending circumferentially around the closure from a first end to a second end;
- a plurality of frangible members extending across the line of weakness to couple the cylindrical wall and the retention band;
- a hinge located between the first end and the second end of the line of weakness, the hinge pivotally coupling the retention band and the top panel;
- and
- a tab coupled to the top panel opposite the hinge with respect to the rotational axis, the tab attached to the retention band by a tab frangible member that is distinct from the plurality of frangible members, the tab restricting pivoting of the top panel relative to the retention band as a result of the tab frangible member being unbroken.
