ABSTRACT:
A fastening insert adapted to be molded into the wall of a plastic container in order to provide a flat, fluid-tight sealing surface on the outer surface of the wall. The insert comprises a rigid annular base and a rigid rib which extends axially outward from the base. A plurality of threaded connectors are provided on the insert. The rigid rib and base prevent the plastic material from shrinking and sagging around the connectors during the plastic curing process.
