Abstract
A liquid container for motor vehicles, especially for an aqueous urea solution, is provided. The container has an interior space into which the liquid can be fed, and also has an upwardly disposed wall to close off the interior space of the container in a fluid type manner. Provided between a maximum liquid level at a maximum filling state in the interior space of the container, and an inner side of the upwardly disposed container wall, is a free space that corresponds to an increase in volume, including the 'blooming', of the liquid that has frozen in the interior space of the container.
