ABSTRACT:
A two piece closure assembly consisting of a metal tamperproof overcap and a plastic recloseable undercap. The metal overcap has a recessed center panel surrounded by a downwardly opening sealing channel. The plastic undercap has a similar configuration but with a slightly narrower sealing channel so as to loosely nest within the overcap in assembled position. The overcap is further provided with a diametrically extending tear strip defined by a pair of parallel score lines. A gripping ear extends from each end of the tear strip at the sealing channel outer edge. The gripping ears besides providing ready access for tearing and removal of the overcap intact are configured to hold the overseal and undercap in assembled position for application as a unit to a container opening.
