УКУПОРОЧНОЕ СРЕДСТВО С ИНДИКАЦИЕЙ ВСКРЫТИЯ, ИМЕЮЩЕЕ СРЕДСТВА СТЕКАНИЯ

摘要

A tamper-indicating closure of integrally molded plastic construction that includes a base wall (30 or 30a) having a peripheral skirt (34 or 34a) with an internal thread (36 or 36a) for engaging an external thread (28 or 28a) on a container finish. A tamper-indicating band (38) is connected to the edge of the skirt by a plurality of circumferentially spaced integral frangible bridges (41). A stop flange (42 or 42a) extends axially outwardly and radially inwardly from an edge of the band remote from the skirt for inversion and engagement with a bead on the container finish. The stop flange is in the form of a circumferentially continuous base (44 or 44a) of uniform thickness circumferentially of the band, and either uniform or increasing thickness radially and axially of the band. A plurality of circumferentially spaced lugs (46 or 46a) are integral with and extend from the base. The lugs widen uniformly from zero thickness at the band to a maximum thickness at the free edge of the flange. The lugs are thus disposed for opposed abutting engagement with the A1 diameter of the container finish beneath the A bead (44 or 44a) on the container finish. The channels or serrations between the lugs permit drainage of liquid from the area between the skirt and the container finish.
