PLASTIC CONTAINER AND METHOD OF FABRICATING SAME Abstract of the Disclosure A nestable plastic trash container having integrally bonded upper and lower plastic lifter bar members to be adapted for automated dumping operation by conventional semi-automatic dumping apparatus is fabricated by initially preforming the lifter bar members by blow molding, inserting the preformed lifter bar members into respective recesses in another blow mold apparatus for forming the main body of the container, and then blow molding the main container body while simultaneously bonding it to the preformed lifter bar members. The insert-receiving recesses of the container body blow mold apparatus and the preformed-lifter bar members respectively have compatible end-to-end convex arcuate surfaces which abut in sealing relation during the blow molding of the container body to prevent escape of the plastic material into the insert-receiving recesses. The bonding surfaces of the preformed insert bar members are similarly convexly arcuate to direct the plastic material of the container body to expand uniformly about the bonding surfaces for bonding thereto of a generally consistent wall thickness of the main container body.
