Abstract:
1. A tamper-indicating closure that includes a plastic shell having a base wall with an annular skirt, at least one internal thread segment on said skirt, a tamper band frangibly connected to said skirt, and a circumferential array of angularly spaced flexible resilient ratchet wings extending counterclockwise from an inner surface of said tamper band at an angle to said inner surface, and a flexible resilient sealing liner on said base wall within said skirt, said liner having a conical sealing surface that faces radially outwardly toward said skirt and axially away from said base wall and said conical sealing surface is resiliently engageable with a trim flange of a container to which said closure is applicable so that said tamper band separates from said annular skirt before loss of sealing engagement between said liner and said trim flange, wherein said ratchet wings extend from said inner surface of said tamper band onto an inner surface of said skirt and frangibly connect said band to said skirt even after said closure is applied to said container.
