The device has a movement sensor e.g. optical movement sensor, provided for detecting an approach of a person to a container, where the device is supplied via a battery or a power supply unit. An interface is controlled in order to provide confirmation about a filling condition of the container to the person, when the approach is detected. A sensor e.g. optical sensor, is provided for detecting the filling condition of the container. Mechanical elements e.g. spring elements, are utilized for lifting and lowering the container. A button element controls a LED, which illuminates the container.
