Abstract: A cooling vessel has a container with an outwardly bent rim and a lid which can be set on the container, as well as a closure device with at least one closure element arranged on the lid, preferably in the region of a rim of the lid. The closure element can swivel about a swivelling axis approximately parallel to an outer edge or to tangent to the outer edge of a rim of the container from an open position which releases the lid from the container into a locking position in which the closure element grips under the container rim, thus forming a pressure-tight seal between the lid and the container. The closure element is designed as a hollow body with an essentially cylindrical or prismatic wall essentially parallel to the direction of the swivelling axis. The wall extends over only a part of the periphery of the hollow body and has a locking wall section which can be pivoted from an open position into a closing position. The closure element rests on a shaped body.
