The invention relates to a liquid container (1) for a motor vehicle, in particular a fuel container (1), having at least one filler tube (4) and having operational and filling ventilation, comprising at least one operational ventilation line (7) which is connected to an equalizing volume of the liquid container (1) and at least one filling ventilation opening (9) which opens into the equalizing volume. The fuel container (1) according to the invention is distinguished by the fact that the operational ventilation opening (7) is connected to the filler tube (4) outside the container volume, in a manner which forms a siphon (8), and that the connection of the operational ventilation line (7) to the filler tube (4) is arranged in such a way that liquid is collected in the siphon (8) during each filling operation and closes the operational ventilation line (7).

1. Liquid container for a motor vehicle having at least one filler tube and having operational and filling ventilation, comprising at least one operational ventilation line which is connected to an equalizing volume of the liquid container, and at least one filling ventilation line, wherein the operational ventilation line is connected to the filler tube outside the container volume, in a manner which forms a siphon and wherein the connection of the operational ventilation line to the filler tube is situated below an outlet-side end of a nozzle which is pushed into the filler tube such that liquid is collected in the siphon during each filling operation and closes the operational ventilation line, characterized in that the filling ventilation line opens into the equalizing volume. 2. Liquid container according to claim 1, characterized in that separate ventilation paths firstly for the operational ventilation and secondly for the filling ventilation are provided. 3. Liquid container as claimed in claim 1, characterized in that the at least one operational ventilation line is connected to the equalizing volume of the liquid container via a valve without a pressure-holding function. 4. Liquid container according to claim 1, characterized in that at least one operational ventilation line is connected with an open line end which is configured as a ventilation nipple to the equalizing volume, without a valve being connected in between. 5. Liquid container according to claim 1, characterized in that a plurality of ventilation lines are connected at different points to the equalizing volume of the liquid container, which ventilation lines are connected to the filler tube so as to in each case form a siphon. 6. Liquid container according to claim 1, characterized in that the filler tube is connected to a fuel vapour filter via at least one droplet separator and/or bubble container. 7. Liquid container according to claim 1, characterized in that the filler tube is connected to a fuel vapour filter via at least one switchover valve. 8. Liquid container according to claim 1, characterized in that the liquid container is configured as a fuel container. 9. Liquid container according to claim 1, characterized in that the liquid container is configured as a storage container for a liquid exhaust-gas additive.
