ABSTRACT:
A removable plug for use in combination with a planar closure having an aperture formed therein. The plug body is of shallow cylindrical configuration and has a top flange which is partially subdivided into inner and outer ring portions by a combination of weak frangible links and strong non-frangible links. A tab integral with the outer ring portion overlies a ledge ring on the closure body to facilitate initialization of the removal process. Location of the pull ring around the maximum diameter of the top flange maximizes leverage and provides a large ring capable of accommodating several fingers of one's hand.
