Abstract:
A method of making a plastic tamper-indicating closure that comprises:(a) molding a closure havinga base wall with a peripheral skirt and internal threads for engaging external threads on a container,an annular tamper-indicating band integrally axially extending from said skirt,a plurality of circumferentially spaced bridges molded on an internal face of said skirt and extending axially into said band, at least one of said bridges having a greater circumferential dimension than the other of said bridges but lesser axial dimension into said band,a thin integral membrane in said band immediately circumferentially adjacent to said one bridge and extending both axially and circumferentially of said band, andstop means on said band for engaging a bead on the container to inhibit removal of the closure from the container,(b) scoring said closure to separate said band from said skirt, but not to severe said bridges, and(c) positioning said step (b) axially with respect to said one bridge such that said band is adapted to remain on the container when the closure is removed by positioning said step (b) not to intersect said one bridge, or to be removed with the closure by positioning said step (b) to intersect said one bridge.
