发明名称 Tamper indicating closure
摘要 A tamper indicating closure comprising a base wall, a peripheral skirt and a band connected with the skirt along a weakened line. The band includes portions that are adapted to engage an annular retaining bead on a container to which the closure is applied. The closure includes a thin membrane extending axially along the lower portion of the skirt, spanning the weakened line and through the band. A thickened band retention column extends radially inwardly from the inner surface of the lower portion of the skirt adjacent the thin membrane, and axially spans the weakened line and extends radially outwardly into the band. When the closure is removed from its position on the container, the score line and thin membrane are broken but the band retention column retains the band on the closure and indicates that the closure has been tampered with.
