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.

Tamper-indicating package, and a closure and container for such a package

A closure for a fluid product dispensing package that includes a tubular body for securement to a container, and having a central flow passage and a cylindrical peg axially spaced from the flow passage. A spout has a dispensing orifice, and is mounted on the base for movement between an open position in which the dispensing orifice is axially spaced from the peg to permit product flow through the passage around the peg and through the orifice, and a closed position in which the dispensing orifice closely surrounds the peg to block product flow. The dispensing orifice is circular, and has three angularly spaced recesses extending radially outwardly from and arcuately around the opening forming air vents with the peg in the closed position of the spout.
