Abstract:
A closure with tamper evident band for sealing a bottle, comprising:a top;a tubular skirt depending from the top;a tamper evident band depending from the tubular skirt, the tamper evident band comprising an annular band having an upper and lower portion and an annular flange having an upper and lower portion, the upper portion of the annular band being frangibly connecting to the tubular skirt, the lower portion of the annular band being resiliently hingedly connected to the lower portion of the annular flange, the annular flange extending from its lower portion to its upper portion in an inward and upward direction, so that in its relaxed position, the annular flange and the annular band define the walls of an annular undercut cavity spacing the upper portion of the annular flange from the annular band, the undercut cavity having a larger diameter than at least a portion of the annular band, whereby the annular band can readily expand outwardly into the annular undercut cavity as the annular flange passes over a bottle neck locking lock during capping, wherein the diameter of the undercut cavity is larger than a diameter of an inside surface of the annular band upper portion.
