COMPOSITE CONTAINER AND PRODUCTION METHOD OF THE SAME, COMPOSITE PREFORM, AND PREFORM

摘要

PROBLEM TO BE SOLVED: To provide a composite container and a production method of the container, by which various functions and characteristics can be imparted to containers, and a composite preform and a preform.SOLUTION: First, a plastics preform 10a is prepared, and a plastics member 40a is disposed to enclose the outside of the preform 10a so as to produce a composite preform 70 having the preform 10a and the plastics member 40a adhered to the outside of the preform 10a. Then a composite container 10A is obtained by heating and inserting the composite preform 70 into a blow-molding die 50 and subjecting the composite preform 70 to blow-molding in the blow-molding die 50 so as to integrally expand the preform 10a and the plastics member 40a of the composite preform 70. The preform comprises a blended resin material and has a monolayer structure.SELECTED DRAWING: Figure 1
