  • Patent number: 4802516
    Abstract: A gas cap containing an elliptical flange such that the flange can be inserted into a nozzle housing of a fuel dispensing device, and rotated to accommodate a variety of different nozzle configurations and yet still provide a means to control the rate at which fuel is dispensed. The elliptical flange element has a concaval surface or recess disposed circumferentially thereto, such that a trigger/handle of a gasoline pump nozzle housing is disposed within said elliptical flange concaval recess, said trigger/handle being stabilized thereby. The gas cap device has a threaded extension that is weighted to provide the device with an asymmetrical center of gravity, such that, as the fuel dispensing actuates to shut off the flow of fuel, the device rotates out of said nozzle handle.
