Abstract
Embodiments of the invention provide a pressure vessel closure apparatus for a pressure vessel having a shell wall, a removable end cap, and an internal retaining groove along an interior surface of the shell wall. The retaining member can include a main-portion outer profile and an end-portion outer profile. The end-portion outer profile can deviate from the main-portion outer profile in order to provide a clearance between the interior surface of the shell wall and the retaining member for the insertion of the retaining member into the retaining groove. A stop can be secured in place with respect to the end cap or the shell wall in order to retain the retaining member within the retaining groove. The retaining member, as retained within the retaining groove by the stop, can retain the end cap within the pressure vessel when the pressure vessel is pressurized.
