A pressure cooker comprises a removable lid carrying at least two jaws connected to a slider to slide on the lid, and a pinion mounted to turn on the lid about an axis that is vertical in operation. Each slider has a rack-forming toothed portion that co-operates with the pinion so that turning the pinion causes all of the jaws to move simultaneously towards one position. A pressure cooker comprises a bowl and a removable lid carrying at least two jaws mounted to move on the lid between a locking position for locking the lid on the bowl (2) and an unlocking position. Each jaw is connected to a slider mounted to slide on the lid so that sliding of the slider causes the associated jaw (3) to move towards one of the positions. A pinion is mounted to turn on the lid about an axis that is vertical in operation. Each slider has a rack-forming toothed portion that co-operates with the pinion so that turning the pinion causes all of the jaws to move simultaneously towards one position. |
