Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyester resin multiple bottle capable of reducing an environmental load and a manufacturing cost, and to provide a method for producing the same.SOLUTION: A polyester resin multiple bottle 1 includes an outline bottle 2 and an inner container body 3 arranged inside of the outline bottle 2, where at least the outline bottle 3 contains a mechanical recycled polyester resin. A method for producing a polyester resin multiple bottle 1 includes: performing blow molding in a state where an inner preform 21 formed by injection molding a polyester resin composition is arranged on the inner peripheral side of an outer preform 22 formed by injection molding a polyester resin composition containing the mechanical recycled polyester resin.SELECTED DRAWING: Figure 2 【課題】環境負荷及び製造コストを低減できるポリエステル樹脂製多重ボトル及びその製造方法を提供する。【解決手段】ポリエステル樹脂製多重ボトル１は、外郭ボトル２と、外郭ボトル２の内部に配設される内容器体３とからなり、少なくとも外郭ボトル３はメカニカルリサイクルポリエステル樹脂を含有する。ポリエステル樹脂製多重ボトル１の製造方法は、メカニカルリサイクルポリエステル樹脂を含有するポリエステル樹脂組成物の射出成形により形成された外プリフォーム２２の内周側に、ポリエステル樹脂組成物の射出成形により形成された内プリフォーム２１を配置した状態でブロー成形する。【選択図】図２
