ABSTRACT OF THE DISCLOSURE A tamper-proof cap and neck assembly made of stretchable plastic material in which the neck has portions fitted within and about a short metal neck portion of a container which serves as a rigidifying back up for the plastic neck and for a locking shoulder on the neck to provide a deflection resis- tant structure and thereby prevent a tamper-indicating ring connected to the cap from slipping off the shoulder without tearing upon initial unthreading of the cap, This rigidified structure also facilitates application of the tamper-indicat- ing ring during initial threading of the cap onto the threaded neck at which time the ring is stretched over the shoulder by a capper bead which engages force-transmitting posts integral with the ring for forcing the ring over the locking shoulder, the band being stretched between the posts and extending beneath the shoulder as chordal segments.
