Abstract
A filling device includes a filling pipe to extend into a liquid container for fluidic connection to the liquid container, a filling head operatively connected to the filling pipe, a venting pipe to vent the liquid container, the venting pipe having an open venting pipe section at an end thereof, and an indicator member configured to visually indicate a filling condition of the liquid container. During a filling sequence of the liquid container in a condition in which the liquid container is not full of liquid, the indicator member is to be impinged upon by outflowing air in the venting pipe at a force such that the indicator member assumes a first recognizable condition. During a filling sequence of the liquid container in a condition in which the liquid container is full of liquid, the indicator member is not impinged on by outflowing air in the venting pipe at a force such that the indicator member assumes a second recognizable condition.
