摘要： A tamper-indicating closure of integrally molded plastic construction that include a base wall having a peripheral skirt with internal threads for engaging external threads on a container finish. A tamper-indicating band is connected to the edge of the skirt by a plurality of circumferentially spaced integral frangible bridges. A stop flange extends from an edge of the band remote from the skirt for engagement with a bead on the container finish. The stop flange has a circumferentially continuous free edge remote from the band disposed in a plane parallel to the base wall. A plurality of circumferentially spaced openings are disposed in the stop flange adjacent to the band for drainage of liquid from between the closure skirt and the container finish. A plurality of circumferentially spaced gussets in the stop flange are at the free edge of the ring, with each gusset being disposed between an adjacent pair of drainage openings. The gussets function during inversion of the stop flange, from an axially outward orientation as molded to an axially inward orientation for use, to absorb compressive stresses on the flange and thereby isolate portions of the flange surrounding the drainage openings from such compressive stresses. A plurality of circumferentially spaced lugs are molded on the inside surface of the closure for opposed abutment with the bead on the finish to help facilitate drainage from between the skirt and finish.
