Abstract

A threaded closure is provided with a snap-fit ring. A snap-fit tamper-evident band with three concentric portions is provided such that the first portion engages the closure's snap-fit ring and is removed from the rest of the band when the closure is rotated off of the container neck. A second portion includes tabs for engaging, e.g., an annular ring on a container neck. A third portion remains on the container neck when the first portion and the cap are rotated off. A number of frangible posts are also provided for connecting the first portion to the second and third portions.
