Abstract

A die head assembly for blow molding a plastic container such as a fluid container used commercially in the dairy industry, for example, is disclosed. The die head assembly includes a die member with an opening and a mandrel at least partially received in the opening. One of the die member opening and the external surface of the mandrel has a generally rectangular conformation. The parison introduced therein is forced into corner regions of the blow mold. The assembly and method removes ovalization of the parison and allows the plastic to reach the corners of the mold with less stretching. A plastic container results with walls having a greater control of sidewall thickness.
