ABSTRACT:
A method of ejecting containers from a blow mold comprises the steps of: opening a blow mold containing containers, the blow mold comprising a pair of pistons having a head and a heel, an end cap disposed behind the heel, and a pair of ejector rods, each ejector rod coupled to a different piston; simultaneously with the opening forcing a fluid against each head of each of the pair of pistons, extending each of the ejector rods to maintain contact with an opposite side of a center portion of the containers in the blow mold and pushing the containers from the blow mold; and forcing a fluid against the heel of each of the pair of pistons operative to retract the pair of ejector rods away from the containers when the containers are separated from the blow mold.
