Disclosed is ventilator mask comprising an upper part of an elastic material and a mask body, wherein the upper part of the mask is joined with the mask body of the ventilator mask by a mask connection region, wherein a wall of the upper part of the mask bounds at least in certain regions of the wall a cavity which is filled with a filler at least in certain regions of the cavity and the cavity is formed at least in certain regions of the cavity along the periphery of the upper part of the mask.

1. A ventilator mask comprising an upper part of an elastic material and a mask body, wherein the upper part of the mask is joined with the mask body of the ventilator mask by a mask connection region, wherein a wall of the upper part of the mask bounds at least in some regions of the wall a cavity
1. A ventilator mask comprising an upper part of an elastic material and a mask body, wherein the upper part of the mask is joined with the mask body of the ventilator mask by a mask connection region, wherein a wall of the upper part of the mask bounds at least in some regions of the wall a cavity which is filled with a filler at least in some regions of the cavity and the cavity is formed at least in some regions of the cavity along a periphery of the upper part of the mask, wherein, on a side that faces away from the mask body, the upper part has an inwardly formed, peripheral contact lip to form a soft and flexible contact zone, wherein the upper part of the mask has no cavity for the filler in a region that is adapted/configured to contact a bridge of a nose of a patient, where the cavity is inhomogeneously filled with filler in such a way that some regions of the filler that are adapted/configured to be close to a face of a patient are softer and more elastic than other regions of the filler, the contact lip being capable of providing an air seal in the region of the bridge of the nose. 2. The ventilator mask of claim 1, wherein an amount of filler and/or a filler property is different in at least two locations along the periphery of the upper part of the mask. 3. The ventilator mask of claim 1, wherein the amount of filler and/or a filler property is different in at least two locations along a cross-section of a surface the cavity. 4. The ventilator mask of claim 1, wherein a shape of the cavity and/or a size of the cavity differs in at least two locations along the periphery of the upper part of the mask. 5. The ventilator mask of claim 1, wherein a thickness of the wall differs in at least two locations along the periphery of the upper part of the mask. 6. The ventilator mask of claim 1, wherein properties of the filler are inhomogeneous, at least in some regions, along the periphery of the upper part of the mask. 7. The ventilator mask of claim 1, wherein properties of the wall are inhomogeneous in at least some regions thereof, along a cross section of the upper part of the mask. 8. The ventilator mask of claim 1, wherein properties of the filler are inhomogeneous, at least in certain regions along a cross section of the upper part of the mask. 9. The ventilator mask of claim 1, wherein the filler has different degrees of viscosity or hardness along a cross section of the upper part of the mask. 10. The ventilator mask of claim 1, wherein the cavity of the upper part of the mask has a variable depth along its cross section. 11. The ventilator mask of claim 1, wherein the filler is a gel. 12. The ventilator mask of claim 11, wherein the gel is a silicone gel or a polyurethane gel. 13. The ventilator mask of claim 1, wherein the filler is a foamed material. 14. The ventilator mask of claim 1, wherein the filler is one of a liquid, a gas mixture, and agarose. 15. The ventilator mask of claim 1, wherein the upper part of the mask has a wall of minimal thickness in a region of the bridge of the nose. 16. The ventilator mask of claim 1, wherein, at least in some regions, the filler has a hardness between 20 Shore OOO and 5 Shore OO. 17. The ventilator mask of claim 1, wherein, at least in some regions, the filler has a hardness between 10 Shore OO and 20 Shore OO. 18. The ventilator mask of claim 1, wherein a thickness or depth of the filler varies along a cross section of the upper part of the mask. 19. A method of producing an upper part of a ventilator mask, wherein the method comprises forming the upper part of the mask of a flexible material, providing the upper part with a cavity at least in some regions thereof, and with at least one hole through which filler can be introduced into the cavity, using a gel as the filler, and inhomogeneously filling the cavity with the filler so that some regions of filler in the upper part of the mask are softer and more elastic than other regions in the upper part of the mask. 20. The method of claim 19, further comprising inserting the filler in the cavity in the form of a sealed body. 21. A method for producing an upper part of a ventilator mask, wherein the method comprises producing a shaped rim by spraying filler from a nozzle onto a wall of the upper part of the mask, the applied amount of filler being varied to achieve a desired shaping of the rim, and the filler only being introduced on an inner surface or an outer surface of walls of the upper part of the mask. 22. The method of claim 21, wherein a gel or a foamed material is used as the applied filler. 23. The method of claim 21, wherein the rim sprayed onto the wall is provided with a protective layer.
