Abstract: The invention relates to a tank cover for mounting on a filler neck of a container, including a grip cap, a threaded part and a locking mechanism which is provided between the grip cap and threaded part, wherein the locking mechanism is formed by latching noses and by elastically deformable latching lugs interacting therewith, the latching lugs are integrally formed on the threaded part and the latching noses are integrally formed on the grip cap, or the latching lugs are integrally formed on the grip cap and the latching noses are integrally formed on the threaded part. Here, the latching lugs are formed on or in the vicinity of a thread turn of the threaded part.

Abstract: An insert for a filler neck of a urea container in diesel-operated motor vehicles, preferably lorries, wherein two plastic components which preferably engage into one another and receive, between them, a preferably annular component which is composed of magnetic material and is magnetized permanently before the installation, are welded to one another in a gas-tight and liquid-tight manner.

Abstract: A closure cap for the filler neck of a reservoir, in particular, one for fuel or motor oil for e.g. motor vehicles, comprising a grip and a rotating lifting device whose first part (sealing part) facing the grip is provided with a sealing ring and whose other part (tightening part), which faces away from the grip and which is provided with detent lugs serving to engage under a closure cap of the filler neck, can be turned relative to the filler neck when the closure cap undergoes a turning motion. The other part (tightening part) can, when the grip undergoes a turning motion, be axially displaced relative to the first part (sealing part) of the rotating lifting device against the force of a spring.
