PURPOSE: To reinforce a mouth part with a high strength and a high reliability by a method wherein a reinforcing member connecting a mouth part to a bottom wall part of a pressure container is provided inside the pressure container, and at least one of upper and lower ends of the reinforcing member is screwed to be mounted. CONSTITUTION: In a synthetic resin pressure container, a cylindrical reinforcing member 10 made of a synthetic resin material or the like is provided. In the reinforcing member 10, openings, such as a plurality of slits, are formed for communicating the inside of the reinforcing member 10 with the inside of the pressure container. The upper end of the reinforcing member 10 is screwed into the inner peripheral surface of a lower end of a mounting ring member 22 to be integrally connected thereto. In addition, a reinforcing screw part projecting from the center of the lower end of the reinforcing member 10 is passed through a hole of a reinforcing mounting part of a bottom cover screwed to be mounted on the bottom part of a pressure container body. By screwing a fastening member to the reinforcing screw part and fastening the fastening member, a mounting mouth part 3 of the pressure container body is pressed downward. As a result, an initial load is imparted to radially shrink the mounting mouth part 3. |
