Abstract
A liner includes a covering portion that covers an inner surface over the entire circumference of the inner surface of a flange portion of a mouthpiece. A covering opposing portion, which is the inner surface of the flange portion and covered with the covering portion, includes a holding groove and a seal groove on the radially outer side of the flange portion. In an axial cross-section of a pressure container, the holding groove extends, from its groove opening toward groove bottom, in a direction inclined toward a radially inner side of the flange portion with respect to a boss portion axial direction, and the seal groove extends, from its groove opening toward groove bottom, in a direction different from the direction of the holding groove. The covering portion includes a holding rib fitted into the holding groove and movable therein, and a seal rib fitted into the seal groove.
