Abstract
Abstract A tamper-indicating closure and package comprising a one-piece molded closure of plastic which threads onto a container such that when the closure is unthreaded, a tamper-indicating band becomes separated from the lower end of the closure skirt. The tamper-indicating band is joined to the closure along a weakened frangible line. A flexible annular wall is formed within the band and extends inwardly and upwardly when the closure is applied to container finish. The band further includes a plurality of circumferentially spaced flexible walls extending circumferentially and fastened at their circumferential ends to the inner surface of the annular wall and having portions intermediate their ends which extend radially inwardly. When the closure is applied to the container, the intermediate portions of the circumferentially extending walls are flexed radially outwardly intermediate their ends over the annular bead on the container and then flex radially inwardly beneath the annular bead while the annular wall is interposed between the skirt of the closure and the annular bead on the container. When the closure is unthreaded, the upper edges of the circumferentially spaced circumferential walls engage the underside of the bead and cause the band to sever along the weakened line.
