Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a stretch blow double container capable of introducing air between an inner cylindrical body and an outer cylindrical body in a stable manner, and capable of discharging a content put in the inner cylindrical body effectively at all times.SOLUTION: In a stretch blow double container 20 consisting of an outer cylindrical body 1 and an inner cylindrical body 3 inserted into the outer cylindrical body 1 and fixed, convexoconcave parts 15a and 15b are formed in the outer cylindrical body 1 and the inner cylindrical body 3 to engage them temporarily, and the convexoconcave parts 15a and 15b are held in a non-engagement state so that an air space 17 is formed between the inner surface of the outer cylindrical body 1 and the outer surface of the inner cylindrical body 3. An air hole 13 leading to the air space 17 is formed at the neck part of the outer cylindrical body 1.SELECTED DRAWING: Figure 1 【課題】内筒体と外筒体との間に安定して空気を導入することができ、内筒体に充填された内容物の排出を常に効果的に行うことが可能な延伸ブロー二重容器を提供する。【解決手段】外筒体１と、外筒体１の内部に挿入されて固定されている内筒体３とからなる延伸ブロー二重容器２０において、外筒体１及び内筒体３には、両者を一時的に係合させるための凹凸１５ａ，１５ｂが形成されており、凹凸１５ａ，１５ｂが非係合状態に保持されており、これにより、外筒体１の内面と内筒体３の外面との間に空気層１７が形成されており、外筒体１の首部には、空気層１７に通じる空気孔１３が形成されていることを特徴とする。【選択図】図１
