ABSTRACT:
A tamper indicating package comprising a container having a body portion and a neck portion having external threads thereon and a plastic 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 is connected by a plurality of integral bridge portions to the skirt of the closure. The annular bead on the container and the radial bead on the tamper indicating band have interengaging portions which are operable during unthreading of the closure to shear the bridge portions. Some of the bridge portions are shaped to readily withstand the forces encountered in applying the closure and other of the bridge portions are shaped to be readily severed in removing the closure.
