In a multilayer pressure container (1) constructed by covering a thin wall container made of synthetic resin or the like with a resin-impregnated fiber-reinforced layer and subsequently curing the impregnating resin, the present invention provides a sealing structure for a high-pressure container which allows sealing measures to be phased in during assembly before curing. The sealing structure for a high-pressure container (1) includes a resin liner (2) adapted to contain gas or liquid; a fiber-reinforced plastic layer (3) adapted to reinforce an outside face of the resin liner (2); and a metal mouthpiece (4) used to pour and discharge the gas or liquid, protruding outside the fiber-reinforced plastic layer (3), wherein a filler neck (21) for the gas or liquid is formed on the resin liner (2), protruding outward from inside the high-pressure container, coupling structures (23 and 43) are formed on a protrusion of the filler neck (21) and the mouthpiece (4), and the mouthpiece (4) is coupled with the resin liner (2) by means of the coupling structures (23 and 43) so as to cover the filler neck (21). |
