Zusammenfassung: | Disclosed is a pressure vessel including an upper liner portion including a top insertion-injection molded and coupled to a peripheral part of a boss portion in which a through hole extends in a vertical direction, extending downward cylindrically from the top to form a first accommodation space accommodating a fluid and having an open lower center, and including a first shape-matching portion in which a first overlapped-coupled surface is formed on a bottom end edge to be perpendicular to a laser emission direction and extends in a vertical direction along a circumferential direction and a lower liner portion having a top end edge coupled to the bottom end edge of the upper liner portion. |
