    摘要: Apparatus for injection molding a multilayer container or a multilayer container preform includes an injection mold cavity and a nozzle for injecting resin into the cavity from at least first and second resin sources in sequence to form a multilayer container or preform in which at least one layer of resin from the second source is disposed between layers of resin from the first source. A deflector element is selectively positionable within the mold cavity during injection of resin from the second source to distribute the resin from the second source during injection such that the layer of resin from the second source is disposed between layers of resin from the first source that preferably are of substantially equal thickness. The mold cavity preferably has a gate through which the resins are injected, and the deflector element preferably is selectively positionable within the cavity adjacent to the gate.
