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 |
