A filling element for filling containers includes a tulip that moves, under the influence of a controller, between two positions, one of which seals the container. A first seal seals a junction between the tulip and a filling-element housing. First and second filling-element regions are respectively outside and inside a clean space of a filling machine. The tulip and a dispensing opening are in the second region. The second seal connects by its first free to the tulip. This second seal seals a junction between the tulip and the two filling-element regions.

1. A filling element for filling containers with liquid contents, said filling element comprising a filling element housing that has at least one dispensing opening on a housing portion for the controlled dispensing of the liquid contents into a container and a sealing tulip that, by way of a controller, can be moved relative to the housing portion parallel to a filling element axis between a raised position and a lowered position in which the sealing tulip lies in sealed position with an opening edge of the container, with the sealing tulip being connected to the filling element housing by a first sealing element to seal a junction between the sealing tulip and the filling element housing, with the first sealing element being provided between the housing portion and the controller, and with the filling element comprising a first filling element region that is arranged outside a clean space of a filling machine, and a second filling element region that comprises the sealing tulip and the dispensing opening and that is arranged in a clean space of a filling machine, wherein a second sealing element is connected by a first free end to the sealing tulip, surrounds an outer periphery of the sealing element radially outside the control means, and seals the junction between the sealing tulip and an interface between the first and second filling element region formed by a separating device. 2. The filling element of claim 1, wherein the sealing tulip and the first sealing element surround the housing portion on its outer or enveloping surface while forming an annular gap between the outer surface of the housing portion and an inner surface of the sealing tulip and of the first sealing element. 3. The filling element of claim 1, wherein the second sealing element surrounds the first sealing element concentrically or essentially concentrically. 4. The filling element of claim 1, wherein at least a partial length of the controller is provided in an interspace located between the first and second sealing element. 5. The filling element claim 4, wherein a positive pressure or a negative pressure can be applied to the interspace located between the first and second sealing element. 6. An apparatus comprising a filling element for causing liquid content to fill a container that has an edge, wherein said filling element extends along a filling-element axis, wherein said filling element comprises a first filling-element region, a second filling-element region, a filling-element housing, a sealing tulip, a first sealing-tulip controller, a first seal, a second seal, and an interface, wherein said filling-element housing comprises a filling-element housing portion, wherein said dispensing opening is on said filling-element housing portion, wherein said dispensing opening is configured to cause controlled dispensing of said liquid content into said container, wherein said first sealing-tulip controller moves said sealing tulip relative to said filling-element housing portion along a direction that is parallel to said filling-element axis, wherein said first sealing-tulip controller moves said sealing tulip between a raised position and a lowered position, wherein, in said lowered position, said sealing tulip lies sealed with said opening edge of said container, wherein said sealing tulip is connected to said filling-element housing by said first seal in order to seal a junction between said sealing tulip and said filling-element housing, wherein said first seal is disposed between said filling-element housing portion and said first sealing-tulip controller, wherein said first filling-element region is outside a clean space of a filling machine, wherein said second filling-element region comprises said sealing tulip and said dispensing opening, wherein said second filling-element region is arranged in said clean space, wherein said second seal is connected by a first free end thereof to said sealing tulip, wherein said second seal surrounds an outer periphery of said seal radially outside said first sealing-tulip controller, wherein said second seal seals a junction between said sealing tulip and said interface, wherein said interface is between said first filling-element region and said second filling-element region, and wherein said interface is formed by a separating device. 7. The apparatus of claim 6, wherein said sealing tulip and said first sealing element surround an outer surface of said filling-element housing portion, thereby forming an annular gap between said outer surface and an inner surface of said sealing tulip and of said first seal. 8. The apparatus of claim 6, wherein said second seal surrounds said first seal, and wherein said first and second seals are concentric. 9. The apparatus of claim 6, further comprising an interspace between said first seal and said second seal, wherein said first sealing-tulip controller has a portion that is disposed within said interspace. 10. The apparatus of claim 6, further comprising an interspace between said first seal and said second seal, wherein said interspace is pressurized. 11. The apparatus of claim 10, wherein said interspace is negatively pressurized. 12. The apparatus of claim 6, further comprising a pressure sensor disposed for monitoring a pressure within an said interspace between said first and second seal. 13. The apparatus of claim 6, wherein at least a section of said first sealing-tulip controller is guided in said filling-element housing. 14. The apparatus of claim 6, wherein said second seal is connected to said filling-element housing by a second free end thereof, said second free end being furthest from said sealing tulip. 15. The apparatus of claim 6, further comprising a second sealing-tulip controller, wherein said first and second sealing-tulip controllers are distributed about said filling-element axis. 16. The apparatus of claim 6, wherein at least one of said first seal and said second seal comprises a bellows. 17. The apparatus of claim 6, wherein said filling-element housing portion is cylindrical. 18. The apparatus of claim 6, further comprising a channel for introducing a cleaning agent into an annular gap between seal sealing tulip and said filling-element housing portion. 19. The apparatus of claim 18 wherein said channel opens out into said annular gap at a channel end furthest away from said sealing tulip. 20. The apparatus of claim 6, further comprising a rotor that rotates about a vertical machine axis, wherein said filling element is one of a plurality of identical filling elements disposed along a periphery thereof.
