    摘要： A manufacturing method of a resin container includes continuously supplying a base material resin forming a container body from a main extruder, discharging from a discharge portion provided in a die head a sub-material supplied from a sub-extruder so that the sub-material joins the base material resin, extruding a parison from a slit portion opened on an end side of the die head, and blow-molding the parison, thereby forming a coating layer which covers the whole or a part of the container body by using the sub-material. A thickness reducing portion in which a thickness is continuously reduced is formed in the coating layer while adjusting a resin pressure in a supply path of the sub-material fed from the sub-extruder by performing suck-back control which pulls back the sub-material from the discharge portion at an arbitrary timing when joining the sub-material with the base material resin.

    摘要： An apparatus for producing a parison having a plurality of resin layers and at least one resin layer of varying thickness is disclosed. The parison is used to form containers in a blow mold machine. An extruder is in communication with a flow head to form the parison. The apparatus includes a valve block having a duct providing communication between a second extruder and the flow head. Flow of resin from the second extruder directly to the flow head is controlled by a valve in the valve block. An accumulator cylinder and piston are also in communication with the duct and control the resin pressure within the duct. Opening and closing the valve and stroking the piston sends resin from the second extruder to the flow head and forms a resin layer having a varying thickness on the parison. A method of forming a varying layer is also disclosed.
