Tamper-indicating closure with lugs on a stop flange for spacing the flange from the finish of a container |
摘要 |
A tamper-indicating closure of integrally molded plastic construction that includes 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 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 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 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 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.
