  • Patent number: 5785920
    Abstract: A rod 3 is driven forward to open an annular slit 5 between a die 2 and a mandrel 4 and the molten resin in a resin accumulation chamber 10 is expelled from annular slit 5 to form a parison. In this operation, the die 2 is displaced from an original position adjoining to the mandrel 4 (axially aligned position) upon opening of the annular slit 5 to correct for any variation in thickness of parison P to be extruded from the annular slit 5. Then, the molten resin accumulated in accumulation chamber 10 is expelled from annular slit 5 to form parison P. The die 2 is then reset to the original position to bring the die 2 and mandrel 4 into axial alignment. Therefore, as the rod 3 is driven back, the annular slit 5 can be closed tight by the mandrel 4 to prevent resin leakage. After closure of the annular slit 5, molten resin is accumulated again in the accumulation chamber 10 and the annular slit 5 is opened. This procedure is repeated to produce parisons on an intermittent basis.

  • Patent number: 5571470
    Abstract: A very thin inner layer composed of a polymer chosen for its barrier and/or inertness properties is fabricated within a container preform constructed mainly from another polymer, or a structure of polymers. The inner layer on the preform is produced either by a controlled coating method involving coating of the injection mold core rod prior to injection molding or by a coating applied directly to the preform after injection molding. This enables both inner and main layers to be brought together at a time when the interface between them is molten. A tie layer can be employed, when desirable, to enable the layers to be combined without melting the layer interface.

  • Patent number: 5540878
    Abstract: A blow molded multilayer plastic article having a large number of layers is formed. First and second diverse thermoplastic streams are extruded into a coextrusion feedblock. In the feedblock the streams are divided into multiple streams and arranged into a first composite stream having a substantially uniform distribution of the layers. The first stream is fed into an interfacial surface generator in which the stream is manipulated to form a second composite stream having even more layers of substantially uniform thickness. This second stream is then formed into a preform such as by injection molding and this preform is blow molded. The second composite stream and preform are formed so that the layers of first and second materials lie generally parallel to a critical surface and possess substantial uniformity when blow molded.

  • Patent number: 5186875
    Abstract: A method of manufacturing a multi-layer hollow article which consists of extruding a multi-layer parison having at least a chief resin layer, a sub resin (barrier) layer, and an adhesive resin layer located between the chief resin layer and the sub resin layer. The adhesive resin layer is made of the same essential material as the chief resin material and of the same quality. The sub resin layer is cut off by the use of a raised extrusion pressure of the adhesive resin when the multi-layer parison has been extruded a predetermined length. The parison is received in a mold so that the cut off sub resin (barrier) layer lies within the mold below pinch offs. Flash is produced as a result of the molding. The flash consists of the chief resin material or the chief resin material and the adhesive resin material. The flash is recycled as part of the chief resin material. Collecting a flash of a hollow article made by a blow molding and rebirthing the flash a rebirth chief resin material.
