ABSTRACT:
A molded nipple connection system for permanently molding a metal nipple within a plastic container that is not susceptible to expansion/contraction forces incurred by the plastic container. The inventive device includes a metal nipple having a threaded end or a cincture surrounded end, a lumen, an immersion end positioned within the plastic during molding, and a plurality of openings adjacent the immersion end. The plurality of openings allow the liquefied plastic during molding to project through the exterior surface of the metal nipple into the lumen of the metal nipple where it is joined with liquefied plastic within the lumen of the metal nipple. After hardening of the plastic, the mold is removed and the metal nipple is captured within the plastic container because of the plastic-securing loop created through the plurality of openings. The plurality of openings are preferably slots, however they may comprise various other well-known shapes.
