ABSTRACT:
A co-injection nozzle having a central injection channel with an open end and providing an injection path for injecting streams of melt materials to form a multi-layer article from the melt material streams. The nozzle comprises interfitting axially concentric members, including at least an interfitting shell and an outer nozzle cap, each having inner and outer surfaces. The nozzle cap has an inner surface with a frustoconical portion enclosing at least a portion of the outer surface of the interfitting shell. An enclosed portion of the outer surface of the shell has a frustoconical shape. The outer and inner frustoconical surface portions are adapted and cooperate to form an annular melt material flow passageway having a fixed tapered frustoconical portion of substantially invariable dimension which terminates at a fixed, annular orifice whose dimension is substantially invariable for flow of a melt material therethrough, for injection of the material from the nozzle.
