An injection molded thermoplastic closure for a container having a generally planar wall and an integrally molded push-in tab within the area of the wall. The push-in tab has its boundary formed by discontinuities in the closure wall and the discontinuities are hermetically closed with a sealant applied locally in an arcuate pattern by rotation of the closure relative to a sealant applicator. A hinge line of the push-in tab has a construction that improves hinge integrity.

Rotor-type dispenser

A tamperproof dispenser end closure includes a base and a rotor pivotally connected to the base by a hub. The base and rotor have webs provided with means defining respective dispensing apertures. The base and rotor are retained in a close superposed relationship to each other by the hub. Frangible means are provided which tear or break when an attempt is made to separate the base from the rotor so that the base and rotor cannot be pivotally connected again by the hub.
