The present invention relates to a multilayer composite having barrier properties, objects, in particular fuel containers, comprising the same, a process for producing the multilayer composite or the objects comprising the same and also the use of the multilayer composite or the objects for reducing the emission of volatile organic compounds.

Multilayered composite material and objects made therefrom

The invention relates to a storage tank () in a motor vehicle for receiving an aqueous urea solution for the SCR of nitrogen oxide in the exhaust gas. The storage tank () comprises a tank body which forms a storage volume () for the urea solution. The storage tank () furthermore comprises a filling pipe for filling the storage volume () and means for venting the storage volume () during the refuelling, wherein the filling pipe () has a filling head () at a remote end, and the filling head () forms an orifice stub (). The orifice stub () defines an orifice () for receiving a fuel pump nozzle. Said orifice stub furthermore has an external thread for receiving a complementary union thread of a refuelling cylinder for refuelling by the gas displacement method. The orifice stub forms at least one secondary air opening when the refuelling cylinder is attached, and therefore, when a refuelling cylinder is attached, a sealing seat is bridged by the refuelling cylinder and refuelling by the gas displacement method is possible even if counterflow venting through the filling tube () does not take place.

The invention relates to an operating-fluid container () for a motor vehicle, comprising a container body which is assembled from two mutually complementary injection-molded shells () which consist of thermoplastic material and are welded together in an encircling manner to form a substantially closed hollow body, wherein at least one shell () is at least in regions formed from thermoplastic materials having different strengths, wherein at least one part-region consists of a thermoplastic material having a fibrous filling, wherein the shell () has been obtained by way of a co-injection process during injection molding.

Operating-fluid container

The invention relates to an operating fluid tank () for a motor vehicle, comprising a tank body which is composed of two mutually complementary, injection-molded shells () which are made of thermoplastic material and which are welded circumferentially to one another to form a substantially closed hollow body, wherein at least one shell () is formed at least in certain regions from thermoplastic materials of differing strength and/or elasticity, wherein at least one partial region is formed from a thermoplastic material which is elastically deformable, and wherein the shell () has been obtained by a co-injection process during injection molding.
