Abstract
A pressure vessel is disclosed for holding fluids. The vessel includes a generally cylindrical outer shell fabricated of a substantially rigid, mechanically strong material, and having a generally hemispherical end section with an opening therein. An inner, generally fluid impervious flexible liner is disposed in the outer shell against the inside surface thereof. The liner has a generally hemispherical end section with an opening aligned with the opening in the outer shell. A boss has a neck portion for fitting in the opening in the outer shell. A generally hemispherical extension projects radially outwardly of the boss substantially entirely to the cylindrical configuration of the outer shell against the inside surface of the inner liner to prevent the generally hemispherical end section of the liner from pulling away from the outer shell.
