SEPARABLE MULTI-LAYER CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a separable multi-layer container which existing stretch blow container molding facilities can produce and which is light and is superior in gas barrier properties and facilitates recycling. SOLUTION: This relates to a stretch blow mold container 1 having a container wall made by laminating two types of resin. The resin of an inner layer 7 is made of polyester, and the resin of an outer layer 6 is made of resin containing polyamide and polyester. A container mouth 2 is made of the inner layer 7 resin. The outer layer 6 is jointly formed on the container wall whose thickness is not more than 1/2 of the thickness of a container mouth base 5. The ratio of the inner layer 7 thickness to the outer layer 6 thickness is between 1:1 and 1:3, and the outer layer 6 is made separable from the inner layer 7 at a container shoulder part 12.
