The invention relates to a ventilating device (2) for liquid containers (1), in particular for liquid containers (1) for an aqueous urea solution, including a housing (3) which can be mounted at an opening of the liquid container (1) and has a first opening (4) to the liquid container (1) and a second opening (5) to the surroundings of the liquid container (1), a diaphragm (6) which is arranged within the housing (3), is permeable to air, is impermeable to liquid and is configured in such a way that a deformation of the diaphragm (6) takes place by a pressure change in the liquid container (1), as a result of which the volume within the housing (3) within the diaphragm (6) changes, with the result that the displaced volume leaves the housing (3) via the second opening (5) to the surroundings of the liquid container (1). Furthermore, the invention relates to a liquid container (1) having a ventilating device (2) according to the invention.
