A double-walled vacuum insulated cryogenic liquid container wherein the access conduit is composed of a material whose strength increases with decreasing temperature with the conduit having a wall thickness which varies in a manner such that when the container is holding a cryogenic liquid, the ratio of bending moment stress in the conduit due to a selected applied force to the strength of the conduit material is substantially constant along the length of the conduit.
