  • Plastic container
    Patent number: 6510958
    Abstract: A plastic container comprising two half-shells which are produced by means of injection molding and have parts of the components integrally formed on them during the injection molding. This does away with the need for fastening said components in the plastic container, with the result that the installation process is simplified to a considerable extent. At the same time, installation errors are largely ruled out. The plastic container is suitable for use in motor vehicles, preferably as a fuel tank.
    Type: Grant
    Filed: October 1, 1999

  • FILLER NECK FOR A FUEL TANK OF A MOTOR VEHICLE
    Publication number: 20010042750
    Abstract: Filler neck for a fuel tank of a motor vehicle Filler necks have, as well as the filler pipe, additional lines for venting, valves and compensating reservoirs. Due to the multiplicity of individual parts and connections, filler necks involve a high outlay in terms of assembly and, because of the connections, have high fuel permeation. The new filler neck is to be easily mountable and have low permeation values.
