Abstract
A container assembly includes a plastic container and a tethered closure. In embodiments, a tethered closure includes a cap, a tamper evident band, a plurality of breakaway connectors, and a connecting portion. The plurality of breakaway connectors connect the tamper evident band to the cap. In embodiments, the connecting portion connects the tamper evident band to the cap, and maintains the connection of the cap to the tamper evident band after the separation of the breakaway connectors from the cap.
Claims32
A tethered plastic closure, comprising:
- a cap including internal threads;
- a tamper evident band having a vertical height between about 1 mm and about 4 mm around a majority of a circumference of the closure;
- a plurality of breakaway connectors disposed substantially around the circumference of the closure and connecting the tamper evident band and the cap, wherein the plurality of breakaway connectors break away between the tamper evident band and the cap;
- and
- a connecting portion connecting the tamper evident band and the cap, the connecting portion maintaining the connection of the cap and the tamper evident band after separation of the plurality of breakaway connectors from the cap;
- wherein a ratio of a vertical distance between the cap and the tamper evident band in which the plurality of breakaway connectors are disposed and the vertical height of the tamper evident band is about 0.10 or less.

A container assembly, comprising:
- a plastic container;
- and
- a tethered plastic closure, comprising:
- a cap including internal threads;
- a tamper evident band having a vertical height of about 3 mm or less around a majority of a circumference of the closure;
- a plurality of breakaway connectors disposed substantially around the circumference of the closure and connecting the tamper evident band and the cap, wherein the plurality of breakaway connectors break away between the tamper evident band and the cap;
- and
- a connecting portion connecting the tamper evident band and the cap, the connecting portion maintaining the connection of the cap to the tamper evident band after separation of the plurality of breakaway connectors from the cap;
- wherein a ratio of a vertical distance between the cap and the tamper evident band in which the breakaway connectors are disposed and the vertical height of the tamper evident band is about 0.10 or less;
- and an associated angle of the connecting portion about a vertical centerline of the cap is in a range of about 5° to about 45°.
