Abstract

A closure device for tank filler necks in motor vehicles. The closure device has the object of configuring the tank filling operation to be more comfortable. This objective is achieved in that at least two closure elements are swivel-mounted on the tank filler neck, the closure elements having insertion bevels on their top that are designed in such a way that when a fuel nozzle is placed on them the closure elements swivel and open the tank filler neck.
