In order to improve the sealing performance, the present invention provides a pressure vessel including: a boss unit including a boss extension part provided in a cylindrical shape and a through hole is formed through a central portion along the vertical direction, and a boss flange part integrally extending outward in the radial direction along the circumferential direction at a lower portion of the boss extension part and having the through hole extending vertically in the inner side in the radial direction; a liner unit provided in a container shape and having an accommodation space communicating with the through hole to accommodate fluid therein, an upper portion of which is insert-injected along a lower surface of the boss flange part and sealedly coupled; and a sealing unit which is hermetically coupled to a boundary region between a lower portion of the boss flange part and the upper portion of the liner unit so that the outflow of the fluid accommodated in the accommodation space is blocked.

    실링성능이 개선되도록, 본 발명은 원통형으로 구비되어 중앙부에 상하방향을 따라 관통홀이 관통 형성되는 보스연장부와, 상기 보스연장부의 하부에 원주방향을 따라 반경방향 외측으로 일체로 확장되며 반경방향 내측에 상기 관통홀이 상하방향으로 연장되는 보스플랜지부를 포함하는 보스부; 용기형으로 구비되어 내부에 유체가 수용되도록 상기 관통홀에 연통되는 수용공간이 형성되되, 상부가 상기 보스플랜지부의 하면을 따라 인서트 사출되어 밀폐 결합되는 라이너부; 및 상기 보스플랜지부의 하부와 상기 라이너부의 상부 간의 경계영역에 상기 수용공간에 수용된 유체의 유출이 차단되도록 밀폐 결합되는 실링부를 포함하는 압력 용기를 제공한다.
