Abstract
Abstract 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.

Claim 1
Independent Claim
156 words
A tamper indicating closure comprising a base wall, a peripheral skirt and a band connected with the skirt along a weakened line, said band including means that are adapted to engage an annular retaining bead on a container to which the closure is applied, said closure including a thin membrane extending axially along the lower portion of the skirt, spanning the weakened line and through the band, the thickness of said membrane being less than the thickness of the adjacent portions of said skirt, a thickened band retention column extending along the inner surface of the lower portion of the skirt adjacent the thin membrane, spanning the weakened line and extending into the band, such that when the closure is removed from its position on the container, the weakened line and the thin membrane are broken but the band retention column retains the band on the closure and indicates that the closure has been tampered with.
Claim 2
Dependent Claim
