See full text

An opening-side flange may include a connecting surface including an inclined surface, a corner part, and an annular groove on a bottom-face side. A conical surface part of the inclined surface may be a conical surface of a truncated cone, and may be inclined such that a radially outer end thereof approaches an opening side. The corner part may be a corner formed between the inclined surface and the annular groove, and may function as a sealing surface with the liner. The annular groove may be a part that connects the inclined surface to an outer surface part, and may be a part that is hollowed toward the opening side relative to the inclined surface.
