Cryogenic vessel

A cryogenic vessel (300a, 300b) comprising:

• an inner container (301) having a cylindrical side wall and two end walls, wherein one of said end walls is a first end wall and the other of said end walls is a second end wall,
• an outer container (302),
• an intermediate space (303), which can be evacuated, between the inner container (301) and the outer container (302), and
• a fluid distribution container (100, 200) connected to the first end wall of the inner container or the second end wall of the inner container, said fluid distribution container having a container wall (121, 221) which delimits an internal volume (120, 220) that extends from an edge of a through-hole in the first end wall or the second end wall, into the intermediate space (303), wherein the fluid distribution container is arranged at least partially within the intermediate space (303) and is fluidically connected to the inner container (301) by the through-hole through which fluid in the internal space of the inner container can flow into the fluid distribution container and fluid in fluid distribution container can flow into the internal space of the inner container, wherein the diameter of the fluid distribution container corresponds to the diameter of the through-hole in the first end wall or the second end wall of the inner container, and the fluid distribution container is welded to the edge of the through-hole,
• wherein the container wall (121, 221) of said fluid distribution container has a plurality of openings (111, 112, 113, 211, 212, 213) that are each configured for connection of a line (311, 312, 313) or are each connected to such a line (311, 312, 313), and the container wall (121, 221) of said fluid distribution container has a convex section (101, 201) wherein the convex section (101, 201) is hemispherical (101), and wherein a wall thickness of the container wall (121, 221) at at least one point is less than 90% of a wall thickness of the end wall of the inner container to which the fluid distribution container is connected and more than 10% of the wall thickness of the end wall of the inner container.
