Abstract: Opening/closing safety device to be mounted on a bayonet pan, consisting of a body (1) to which a side handle is attached (11), and a lid (2) to which an upper body is attached (3), which consists of a lever (4) which, when it is in its initial position, guarantees that there is no pressure inside the pan and which, when it is locked (pressure cooker), prevents the pan from opening.

Abstract: The invention concerns a preferably screwable or attachable and twistable closure cap for attaching to a fixed spout, for example of a car radiator, a compensating reservoir in cooling or heating systems or the like, with a screw cap or an attachable and twisting cap and a twistable contact part within which preferably an excess/low-pressure combination valve is concentrically mounted on the cap. The valve has a sealing element which comes into tight contact with the fixed part when the closure cap is fastened. The closure cap, when screwed onto the fixed spout, is prevented from being removed or unscrewed or untwisted by means of a temperature-dependent control element in which the temperature-dependent control element (12) creates a coupling of the cap (2) and the contact part (4) when the temperature is normal and a decoupling when the temperature rises.

Abstract: A one-piece closure for resealing and repressurizing an opened beverage container is provided. The closure comprises a body portion with an annular skirt integral to and descending therefrom. The closure further comprises an annular flange integral to and extending radially inward from the annular skirt. The flange provides an air-tight seal with the sides of a beverage container. The closure is reusable and is especially useful with standard tab-top soda containers.

Abstract: A thermally locking radiator cap for fitting on the filler neck flange of an automotive radiator, which prevents the radiator cap from becoming detached from the filler neck flange when the radiator is hot. The cap uses a bi-metallic strip captured on the top surface of the radiator cap and having an end which goes through the opening of the radiator cap and engages the filler neck flange to lock the cap in place. Colors are placed on the bi-metallic strip adjacent to a window at the top of the radiator cap so that when the bi-metallic strip moves as a result of expansion, the colors change to indicate that the cap is either locked or free.

Abstract: An accumulator having a housing, a spring-loaded liquid inlet-outlet valve, a gas charging and release valve, and a gas-liquid separator in which a top is provided releasably connected to the housing for servicing the accumulator from the top. The top is slidably insertable into the top of the housing and a releasable lock is positioned externally of the top for locking the top in the housing. The lock is prevented from releasing while the top is held in an upward position by pressure in the housing and can only be released when the pressure in the housing is reduced and the top is moved downwardly. The locking means includes a notch in the exterior of the housing, a locking ring, and a backup shoulder on the exterior of the top. An anti-extrusion ring is bonded on the bottom edge of the top and slidably engages the interior of the housing for preventing damage to the separator. Preferably the top includes a dome and an annular flange extending around the lower end of the dome.
