PRODUCTION DEVICE OF COMPLEX PREFORM, COMPLEX PREFORM AND PRODUCTION METHOD THEREOF, AND COMPOSITE CONTAINER AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a production device of a complex preform, in which the complex preform can be produced efficiently, which preform is used for producing a composite container to which various functions such as gas barrier properties or characteristics are imparted, and to provide the complex preform, a production method thereof, and the composite container and a production method thereof.SOLUTION: A production device 100 of the complex preform includes: a supply zone 101 to which a new plastic material-made preform 10a is supplied; a plastic-made member attachment unit 102 which is arranged on the downstream side of the supply zone 101 and is used for attaching a plastic-made member 40a for imparting a heat shrinking function to the preform 10a to the outside of the preform 10a; and a heating unit 103 which is arranged on the downstream side of the plastic-made member attachment unit 102 and is used for heating the plastic-made member 40a so that the plastic-made member 40a imparts the heat shrinking function to the preform 10a.SELECTED DRAWING: Figure 7
