Abstract
A steam pressure container, e.g. for a coffee machine, comprises a lid incorporating a locking mechanism to ensure that the lid cannot be released or removed when the interior of the container is under pressure. The locking mechanism comprises a sealing member made of elastically resilient material and inserted into the lid. The sealing member includes a head portion with locking protrusions to ensure a non-rotatable fixing of the sealing member to the lid. The sealing member further comprises a flange portion penetrating into the flange of the container. The flange portion is provided with a sealing rib at its lowermost end and, thereabove, with a plurality of locking ribs. The latter ones cooperate with a plurality of locking grooves arranged in the inside surface of the container flange. As soon as the container is pressurized, the flange portion of the sealing member is radially deformed outwards and the locking ribs engage the locking grooves, thereby preventing an accidental rotation of the lid.
