A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with an internal thread for engaging a corresponding external thread on a container finish to retain the closure on the finish. A tamper- indicating band is connected to an edge of the skirt by a plurality of spaced integral frangible bridges. A stop flange extends axially and radially from an edge of the band remote from the skirt, being flexibly connected to the band by an integral hinge portion. A plurality of circumferentially spaced openings extend axially through the band adjacent to the hinge portion, forming drain openings through which fluid may drain after the closure is applied to a wet container finish. In the preferred embodiments of the invention, these drain openings are formed by a plurality of circumferentially spaced channels on the radially inner surface of the band extending axially from adjacent to the frangible bridges to open at an axial edge of the band remote from the frangible bridges.
