Abstract
A manufacturing apparatus of a resin container includes a main extruder which supplies a base material resin, and a sub-extruder which supplies a sub-material. The sub-material supplied from the sub-extruder is discharged from a discharge portion provided in a die head so that the sub-material joins the base material resin continuously supplied from the main extruder. A parison is then extruded from a slit portion opened on an end side of the die head, and subjected to blow molding, thereby forming a coating layer which covers the whole or a part of a container body formed of the base material resin by using the sub-material. A suck-back mechanism which pulls back the sub-material from the discharge portion is provided between the sub-extruder and the die head, and the discharge portion is provided in the vicinity of the slit portion in-the die head.
