- 樹脂製のプリフォームの内部に加圧した液体を供給してプリフォームをブロー成形型のキャビティの内面に沿った形状の容器に成形する液体ブロー成形による容器製造方法であって、
前記ブロー成形型として、前記キャビティの内面の一部を形成する本体型部と、前記キャビティの内面の他の一部を形成する可動型部とを備えるものを用い、
前記本体型部の内部に配置した前記プリフォームの内部に加圧した液体を供給して前記プリフォームを膨張変形させる膨張変形工程と、
前記本体型部に対して前記可動型部を膨張変形した前記プリフォームに向かう方向に相対移動することで前記プリフォームを前記可動型部によって押圧すると共に、該押圧によって前記プリフォームの内部の圧力が上昇し始めるタイミングで前記プリフォームの内部から液体を回収することで、その圧力の上昇を抑制又は阻止する押圧工程と、を有することを特徴とする液体ブロー成形による容器製造方法。 - 前記膨張変形工程において、プランジャーを加圧方向に動かすことにより、前記プリフォームの内部に加圧した液体を供給し、
前記押圧工程において、前記プランジャーを減圧方向に動かすことにより、前記プリフォームの内部から液体を回収する、請求項1に記載の液体ブロー成形による容器製造方法。 - 前記可動型部によって前記容器の底部又は把手部を成形する、請求項1又は2に記載の液体ブロー成形による容器製造方法。
