Abstract
A method of ejecting a container from a blow mold comprises the steps of: opening a blow mold containing a container, 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 one of the pair of pistons; 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 container in the blow mold and pushing the container 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 container when the container is separated from the blow mold.
