PROBLEM TO BE SOLVED: To provide a pressure container that includes an outer shell formed of fiber-reinforced resin material outside of a resin-based container body comprising a direct blow molding, and is excellent in pressure resistance.SOLUTION: A pressure container includes a cylindrical straight barrel part 10, and a dome part 12 provided at both ends of the straight barrel part 10 and formed into a shape tapered as separating from the straight barrel part 10. The straight barrel part 10 and the dome part 12 are formed by a resin container body 2 comprising a direct blow molding, and an outer shell comprising a fiber-reinforced resin material provided outside the container body 2 and containing reinforced fiber and matrix resin, and in the container body 2, a pinch off part 14 is formed only at the dome part 12.SELECTED DRAWING: Figure 3 【課題】ダイレクトブロー成形品からなる樹脂製の容器本体の外側に繊維強化樹脂材料で形成された外殻を備える、優れた耐圧性を有する圧力容器を提供する。【解決手段】筒状の直胴部１０と、直胴部１０の両端に設けられ、直胴部１０から離れるにつれて窄む形状のドーム部１２とを備える圧力容器であって、直胴部１０及びドーム部１２は、ダイレクトブロー成形品からなる樹脂製の容器本体２と、容器本体２の外側に設けられた、強化繊維とマトリクス樹脂を含有する繊維強化樹脂材料からなる外殻によって形成され、容器本体２には、ドーム部１２のみにピンチオフ部１４が形成されている、圧力容器。【選択図】図３
