Abstract: The tamper indicating package comprising a container having a neck, a closure interengaged with the container, and a tamper indicating device comprising a plurality of radially extending legs adapted to extend radially outwardly and axially about the closure. The legs are joined to one another at their inner ends and an integral annular band joins the other ends of the legs. The band extends beneath the flange of the container when the device is applied over the closure on the container, and the legs are made of a material such that the band will snap and/or shrink radially inwardly after application of the device to a position beneath the flange of the container thereby providing a tamper indicating device.

Abstract: A tamper indicating package comprising a container having a body portion and a neck portion having external threads thereon and a closure having a top wall and a peripheral skirt having internal threads adapted to engage the threads on the neck of the container. A tamper indicating band extends downwardly from said skirt and an integral weakened portion interconnects the band to the skirt. The container has an annular bead spaced below the threads on the neck and a radially inwardly extending bead adapted to engage the annular bead on the container when the closure is threaded on the container. The annular bead on the container and the radial bead on the tamper indicating band having interengaging portions which are operable during unthreading of the closure to shear the bridge portions.

Abstract: A tamper indicating package comprising a container having a neck finish with a large opening and threads on the exterior thereof, and an annular bead spaced axially from the threads and away from the open end of the container and a plastic closure having a top wall and a peripheral skirt formed with interrupted threads adapted to engage the threads on the container and an integral tamper indicating band on the periphery of the skirt connected thereto by an internal groove which defines a weakened line and having an interrupted radially extending bead adapted to engage the bead on the container. The bead on the tamper indicating band is interrupted along the same axial plane as the threads on the skirt so that the tamper indicating band is without a bead in substantially the same areas as the portions of the skirt are without threads.
