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.
A vacuum insulated cryogenic container comprising: an inner vessel for holding a cryogenic liquid, said inner vessel having an access opening; an outer shell enclosing said inner vessel in a spaced apart relationship so as to form an evacuable space therebetween, said outer shell having an access opening disposed substantially in alignment with said access opening of said inner vessel; thermal insulation material disposed in said evacuable space; and an access conduit joining said access opening of said outer shell to said access opening of said inner sh...
