A method of processing a polyester composition without changing the intrinsic viscosity of the polyester polymer by more than 0.025 dL/g such as injection molding a PET resin to form a bottle perform and blow molding a container from the bottle preform.

Co-polyester packaging resins prepared without solid-state polymerization, a method for processing the co-polyester resins with reduced viscosity change and containers and other articles prepared by the process

A staged, sequentially separated injection mold () for forming a container spout () having a peripheral flange (), a generally cylindrical sidewall (), a removable panel () fixed within the sidewall, and a pull ring () connected to the removable panel. The mold includes a base (), and a first element () coupled to the base including a gate (). A core plate () movable with respect to the base, and a core element () confronting the first mold element. A sleeve () surrounds the core element having a channel () to define the pull ring. The sleeve moves with respect to the core element to permit release of a molded pull ring. A stripper ring () surrounds the sleeve with an edge () positioned contiguous to the sleeve outward facing surface, the stripper ring being movable along the sleeve.

Staged, sequentially separated injection mold

An adjustable cam track for a mold assembly including a first mold portion, a second mold portion movable with respect to the first mold portion, a third mold portion movably interposed between the first and second portions and having at least one pair of space defining surfaces which together with the first and second mold portions defines in a closed position space for receiving plastic material to form at least one molded article. The adjustable cam track includes a guide coupled to the second mold portion, the guide defining a first portion of the adjustable cam track and a cam insert including a second portion of the adjustable cam track defining a point of release of the molded article from the space defining surfaces, the cam insert being adjustably positionable with respect to the guide to adjust the point of release. The first portion of the cam track also includes a ramp to an intermediate portion defining a pre-release position of the space defining surfaces so that the molded article is loosely retained by the space defining surfaces from time the cam follower engages the ramp defining the onset of prerelease until the cam follower reaches the point of full release to facilitate placement of the molded article into an article receiver inserted into the interval between the first mold portion and the molded article at the culmination of the molding cycle.
