Claim:
1. A cryogenic fluid container comprising, in combination: an inner vessel for holding cryogenic fluid; a cylindrically shaped outer vessel having a vertically extending central longitudinal axis and surrounding the inner vessel and forming an insulating space therebetween; end user operating controls located on a top of the outer vessel including a liquid-use valve for selectively dispensing liquid cryogen from the inner vessel, a pressure-building valve for selectively controlling a pressure building circuit for increasing pressure within the inner vessel, and a gas-use valve for selectively dispensing gaseous cryogen from the inner vessel; wherein each of the end user operating controls are located on a front side of the top of the outer vessel; maintenance operating controls located on the top of the outer vessel including an economizer regulator for selectively setting at least one desired pressure of the inner vessel, a vent valve for selectively venting cryogen fluid from the inner vessel, and a vacuum pressure port for indicating vacuum pressure between the inner and outer vessels; wherein each of maintenance operating controls are located on a rear side of the top of the outer vessel; a circular-shaped handling ring secured to the top of the outer vessel and spaced above the end user operating controls and the maintenance operating controls with a pair of ring supports to secure the handling ring to the outer vessel at only lateral sides of the top of the outer vessel to provide unobstructed access to the end user operating controls and the maintenance operating controls below the handling ring on the front and rear sides respectively of the outer vessel; and wherein the handling ring is lobe shaped having horizontally extending side portions and upwardly curved front and rear portions that connect the side portions and extend higher than the side portions.
