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