Cup-shaped vessel with removable partition - has partition inserted in curved shape and bearing against shoulders in vessel walls

摘要

The cup-shaped vessel has a removable partition parallel to its axis and clamped in position between diverging walls. The partition is inserted curved under pre-tension, with its edges against the walls, bearing against the shoulders of steps formed in the latter. The steps extend inwards on the outer side of the partition when seen in the divergence direction. The partition can be pre-curved in the divergence direction, and the steps can run for the entire wall height. The partition can rest on the base of the vessel, in which a shoulder is formed, against which it bears, by a raised portion.
