Summary:To provide a multiplex container that can prevent intrusion of water into a clearance between an inner container and an outer container, which is generated after high-temperature filling.SOLUTION: A multiplex container 1 includes: an inner container 20 for storing a content and an outer container 10 for including the inner container 20 therein, which are laminated so as to be separable; and an outside air introduction hole for introducing outside air into a clearance formed between the inner container and the outer container. The outer container 10 and the inner container 20 are molded using a polyester resin. The outer container 10 has a resin of which intrinsic viscosity is higher than the intrinsic viscosity of the inner container 20.SELECTED DRAWING: Figure 1 【課題】高温充填後に生じる内容器と外容器との間の空隙に対して水が浸入することを防ぐことができる多重容器を提供すること【解決手段】多重容器１は、内容物を収容する内容器２０と、内容器２０を内包する外容器１０とが剥離可能に積層され、前記外容器と内容器との間に形成される空隙に外気を導入する外気導入孔を備えた多重容器である。外容器１０及び内容器２０は、ポリエステル系樹脂を用いて成形され、外容器１０の樹脂の固有粘度が、内容器２０の固有粘度よりも高い。【選択図】図１
