Abstract
An apparatus for discharging a liquid from a container is provided. A mobile unit is disposed in the container in such a way as to be movable therein in a contact-free manner for reducing the volume of the container. A bellows connects the mobile unit in a liquid-tight manner to an inner wall of the container. An interior chamber of the bellows that faces away from the container, together with a housing, form a space that is closed off against the exterior. A spindle, as a drive apparatus, is disposed in this space. The spindle is connected to the mobile unit in the interior chamber of the bellows.
