Abstract: A liquid container for a motor vehicle, especially an urea solution container, comprising, as a container component, a tank surrounding an uptake volume, and, as a further container component, a filling line, which, in flow-mechanics terms, connects an admission location placed outside the tank at a distance from it, with the uptake volume, wherein at least a main section of the tank and at least a main section of the filling line are configured to be rigid so that they in essence remain free of deformity when the liquid container is used as directed, wherein on the tank and/or on the filling line at least one auxiliary tank or auxiliary filling line body surrounded by the filling line that expands the intake volume or the filling line volume, is formed, or is able to be formed by increasing the pressure in the interior of the liquid container.
