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.

Abstract: A preform or parison for manufacturing a container having a large interior diameter body and small interior diameter opening is prepared by molding the preform in two parts, a body having a generally cylindrical sidewall with one open end and one closed end, and a preform end having a diameter sized to mate with the sidewall and an opening therein for accessing the interior of the preform, and then joining the preform body and preform end to form a complete preform having an internal diameter larger than the diameter of the opening. The preform so formed is then used in a conventional blow molding process to produce a container having a large internal diameter and a narrow access opening.
