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.

Dependent claims

In a cooking pot including a container having a wall and an outwardly extending peripheral container rim having an outwardly facing outer edge, a lid for closing said container and having an outwardly extending lid rim to be positioned over said container rim, and a closing mechanism for locking said lid on said container in a pressure tight manner, said closing mechanism including at least one closing element mounted on said lid for swivelling movement about a swivel axis, extending substantially parallel to said outer edge of said container rim or to a tangent to said outer edge when said lid rim is positioned over said container rim, between an open position, whereat said lid is released relative to said container, and a locking position, whereat said closing element extends beneath said container lid and locks said lid to said container, the improvement comprising:

a support body mounted on said lid;
said closing element comprising a hollow body defined by a peripheral wall that is interrupted circumferentially to define a circumferential end edge;
said hollow body being mounted on said support body and being supported thereby for said swivelling movement relative thereto between said open and locking positions and with said peripheral wall extending substantially parallel to said swivel axis;
and
said circumferential end edge extending beneath said container rim when said hollow body is in said locking position and being spaced from said container rim when said body is in said open position.
