Abstract

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.
