Abstract
A pressure container in accordance with the invention is provided with a mouth piece having a cylindrical boss portion and a flange portion which is protruded from an outer periphery of the boss portion and a synthetic resin liner which is integrally formed in the flange portion. In the pressure container, an annular groove to which an inner peripheral portion of an inner edge portion of the liner is fitted so as to slide in a direction of expanding a diameter is provided on an inner side surface of the flange portion. Accordingly, it is possible to improve a reliability of an airtight seal in a bonding portion between a liner and a mouth piece.
