초록 ▼

An apparatus for injection molding a plurality of multilayer, multimaterial plastic containers. A plurality of co-injection nozzles are positioned to feed a plurality of cavities defined by a plurality of injection molds and a source of polymer materials is located upstream of the nozzles. The apparatus also includes a flow channel for each of a plurality of polymer streams to define a path between the polymer source and at least one of the co-injection nozzles such that each of the co-injection nozzles is in communication with one of the flow channels for each polymer stream and the polymer streams enter more than one of the co-injection nozzles. The channels are arranged to provide substantially the same flow experience to each polymer stream.

대표청구항 ▼

[ What is claimed is:] [1.] Apparatus for injection molding a plurality of multilayer, multi-material plastic containers, which comprises:a plurality of injection molds which define injection cavities,a plurality of juxtaposed co-injection nozzles positioned to feed the cavities of the injection molds,a source of polymer materials located upstream of the nozzles, said source of polymer materials creating multiple polymer streams, each of said polymer streams corresponding to at least one layer of said plurality of containers,means defining a flow channel for each polymer stream, each flow channel defining a path between said source and at least one of said co-injection nozzles such that each of said co-injection nozzles is in communication with one of said flow channels for each said polymer stream, wherein said polymer streams enter more than one of said co-injection nozzles;each of said flow channels being separate and having a portion providing substantially the same flow experience for one of said polymer streams entering more than one of said co-injection nozzles.
