초록 ▼

Apparatus for forming multilayered articles including a nozzle communicating with the mold cavity. The nozzle includes a first nozzle channel for feeding a first thermoplastic material to the mold cavity and a second nozzle channel communicating with the first nozzle channel for feeding a second thermoplastic material to the mold cavity. A metered amount of second material is fed from the second nozzle channel to the first nozzle channel and subsequently to the mold cavity by the first material from the first nozzle channel.

대표청구항 ▼

A molding apparatus for molding articles and preforms having multilayered walls, which comprises: at least one mold cavity, said cavity having a nozzle individual thereto with a gate area in the nozzle adjacent the mold cavity; a hot runner system including a first and second conduit means for supplying a first and second thermoplastic material, respectively, to aid mold cavity, each material originating from a separate source, wherein the conduit means define separate and individual channels for each thermoplastic material; heating means associated with the apparatus for maintaining said materials at their appropriate temperatures in said conduit means; a first nozzle channel communicating with said first conduit means, gate area and mold cavity for feeding a first material from said first conduit means to said gate area and thence to said mold cavity; a second nozzle channel communicating with said second conduit means and first nozzle channel; and means for feeding a small metered amount of second material to said second nozzle channel in an amount less than about 3% of the total weight of the material fed to the mold cavity; a valve stem movable in said first nozzle channel; wherein said first nozzle channel has a constricted region adjacent and upstream of said gate area sized to receive said metered amount of second material and a region upstream of the constricted region wider than the constricted region, with the second nozzle channel communicating with the first nozzle channel in said constricted region, including means for moving the valve stem from a forward position seated in the constricted region to block access to the gate area from the first and second nozzle channel, to a position permitting entry of said metered amount of second material into the constricted region while blocking access to the constricted region from the first nozzle channel, to a rearward position in the relatively wider region to open access to the gate area from the first nozzle channel, whereby said metered amount of second material is fed from said second nozzle channel to said constricted region and subsequently to said gate area and mold cavity by first material from said first nozzle channel.
