Abstract
A tank closing device for a container includes a filler neck at the container and a closing member received in the filler neck. A closing cap is securable at the filler neck by a bayonet fitting. A sealing element is arranged at the closing member. A spring rests at the closing cap and biases the sealing element against the filler neck. The closing cap has a top face and a gripping member projecting upwardly from the top face. The bayonet fitting includes at least three socket elements at a circumferential surface of the closure cap or the filler neck and includes at least three dogs cooperating with the at least three socket elements and arranged on an opposing circumferential surface of the closing cap or the filler neck. The socket elements or the dogs or both the socket elements and the dogs are unevenly distributed over the circumferential surface, respectively.
