Abstract A tamper-indicating closure includes a base wall (30) having a peripheral skirt (34) with an internal thread (36) for affixing the closure to the container finish (26). A tamper-indicating band (38) is connected to an edge of the skirt by frangible bridges (40). A stop flange (42) extends from an edge of the band remote from the skirt for abutment with a bead (44) on the container finish to inhibit removal of the closure absent fracture of the frangible means. A plurality of circumferentially spaced openings (60) extend radially through the skirt at a position between the frangible bridges and the internal thread. These openings provide for ingress of cleansing solution during a washing operation after the closure is applied to a container to flush any residue from between the tamper-indicating band and the closure finish. Drain openings (52) are provided in the stop flange and/or the tamper-indicating band to allow drainage of the flushing solution, and also to allow drainage of any accumulated liquid in wet-finish applications.
