Portable pressure vessel and closure

A closure for a pressure vessel for safely storing and transporting an improvised explosive device therein which comprises:

• a spherically shaped body member having a vertical axis, a body bushing bore being disposed therethrough concentric with said vertical axis, an access port disposed in an upper hemispherical side of said body member, and two vessel threaded bores transversely passing therethrough and being proximate to said vertical axis;
• a reinforcing ring member circumferentially welded to the peripheral edge of said access port, said reinforcing ring member being inclined at approximately 45.degree. with respect to said vertical axis of said body member;
• internal door means pivotally held in juxtaposition to said reinforcing ring member for providing rapid unobstructed access through said access port and for rapidly closing said access port of said body member to completely seal said improvised explosive device therein;
• and
• a door stop fixedly welded to said reinforcing lug for stopping said internal door means when it reaches a closed position;
• a pair of reinforcing plates fixedly welded to said body member, said pair of reinforcing plates having plate bushing bores therein axially aligned with said body bushing bore, plate threaded bores passing transversely therethrough and being concentrically aligned with said vessel threaded bores;
• a tubular bushing fixedly positioned in said plate and vessel bushing bores;
• a pair of door closing adjusting bolts threadedly positioned in said plate threaded bores and said vessel threaded bore, said pair of bolts having ends protruding into the interior of said body member;
• a single pivot "T" bar means pivotally positioned in said bushing and rotatably connected to said internal door means for rapidly opening and closing said internal door means.
