PROBLEM TO BE SOLVED: To provide a pressure container excellent in gas seal properties of a base part, the pressure container composed of a thermoplastic liner and a fiber-reinforced resin reinforcement layer.SOLUTION: The problem can be solved by a pressure container comprising: a thermoplastic liner; a fiber-reinforced resin reinforcement layer covering the outer surface of the liner; and a cap, in which a gas seal part between a bulb of the pressure container and the pressure container is included on an inner surface of the liner. It is preferable to manufacture the liner by a blow molding method by setting the ratio of the length of a liner barrel part to the radius thereof to be 2 or more and 12 or less. According to the invention, a pressure container excellent in gas seal properties of a base part in the pressure container composed of a thermoplastic liner and a fiber-reinforced resin reinforcement layer can be obtained.SELECTED DRAWING: Figure 5 【課題】 熱可塑性樹脂ライナと繊維強化樹脂補強層からなる圧力容器であって口金部のガスシール性に優れた圧力容器を提供する。【解決手段】 上記課題は、熱可塑性樹脂のライナと、該ライナの外側面を覆う繊維強化樹脂と、口金とを備える圧力容器であって、圧力容器のバルブと圧力容器とのガスシール部を該ライナの内面に有する圧力容器により解決される。ライナ胴部の長さとライナ胴部の半径の比が２以上、１２以下となる様設定し、ライナをブロー成形法で製作することが好ましい。本発明によれば、熱可塑性樹脂ライナと繊維強化樹脂補強層からなる圧力容器であって口金部のガスシール性に優れた圧力容器が得られる。【選択図】 図５
