ABSTRACT:
A stop boss formed on the handle of a pail may be simultaneously molded along with the pail and its handle by means of a pair of pivotable members which have free ends abutting together in a first pivoting position, and which are spaced from each other in a second pivoting position. The free ends cooperatively define between them a mold cavity for forming the stop boss on the rotatable handle. The pivotable members are adapted to occupy their first pivoting position while the mold assemblies close, and to pivot into the second, open pivoting position upon opening of the mold assembly and removal of the molded part to facilitate removal of the stop boss.
