Method for forming a container from a preform having a coiled handle attached at two attachment points
Abstract:
A method of forming a container from bi-axially orientable plastics material and having an integral handle with the steps of forming a preform having a neck portion and an expandable portion below the neck portion, with the neck portion including a locating ring above the expandable portion and a handle molded to the non expandable at one end and molded to the expandle portion at the other end. Where the molded-in handle is the approximate length of the handle of the finished container. The unblown preform of orientable plastics is inserted into a blow molder and thereafter stretched by a stretch rod. During the stretch process the handle on the preform unbends rather than stretching to form the approximate shape of the handle in the finished container. The blow mold then closes on the stretched preform thus capturing the handle. Blow gas is then injected into the interior.
