Abstract:
1. A safety closure for containers which are under steam pressure, for devices in connection with household applications, such as steam irons, steam cleaning devices and the like, having: an interior element, which can be screwed on a filler opening of the container; and an exterior element in the form of a gripping cap; a coupling member provided between said interior element and said exterior element; a first spring; and a drive mechanism controlled by the pressure in the interior container in such a way that, with the container not under pressure, a connection, fixed against relative rotation, exists between said exterior element and said interior element, which is released when the container is under pressure, wherein: said drive mechanism includes a diaphragm, which is arranged on said exterior element between an annular sealing face on said interior element and a valve disk, which is charged by a second spring, said second spring being an axial overpressure compression spring; said coupling member being movable against the action of said first spring; and said valve disk is embodied in the shape of a hood and constitutes on its inner end facing away from an annular contact face of said overpressure compression spring a radially interior axial guidance device for a diaphragm slide of said drive mechanism.
