To improve a sealing performance, the present invention provides a pressure vessel which comprises: an upper liner unit engaged with an outer side of a boss unit having an upper side with a vertically extended penetrating hole by insert molding, and being cylindrically extended downward from an upper side and opened on a lower center part for forming a first storage space storing a fluid inside, and having a first coupling unit formed on a lower end edge to have a first melted coupling surface inclined and extended from a laser irradiation direction to be vertically inclined and extended in a circumferential direction; and a lower liner unit having an upper end edge engaged with a lower end edge of the upper liner unit, and having a second coupling unit formed on an upper end edge to have a second melted engagement surface coming in surface-contact with the first melted engagement surface to be vertically inclined and extended in a circumferential direction, and having a second storage space formed inside to communicate with the first storage space.

    실링성능이 개선되도록, 본 발명은 상부가 관통홀이 상하방향으로 연장된 보스부의 외곽에 인서트 사출되어 결합되되, 내부에 유체가 수용되는 제1수용공간이 형성되도록 상부로부터 원통형으로 하향 연장되며 하부 중앙이 개구되고, 하단 테두리에 레이저 조사방향으로부터 경사지게 연장되는 제1용융결합면이 원주방향을 따라 상하방향으로 경사지게 연장 형성된 제1형합부가 형성되는 상부라이너부; 및 상기 상부라이너부의 하단 테두리에 상단 테두리가 결합되되, 상단 테두리에 상기 제1용융결합면에 면접촉되는 제2용융결합면이 원주방향을 따라 상하방향으로 경사지게 연장 형성된 제2형합부가 형성되고, 내부에 제1수용공간에 연통되는 제2수용공간이 형성되는 하부라이너부를 포함하는 압력 용기를 제공한다.
