A dispensing device for dispensing a liquid, comprising: a pump, with an elastically deformable or flexible, dome-like section which borders a pump chamber for the liquid or fluidically connected with the liquid, wherein the liquid can be pumped or conveyed by a reversible deformation of the sect
1. A dispensing device for dispensing a liquid, comprising: a pump, with an elastically deformable or flexible, dome-like section which borders a pump chamber for the liquid or fluidically connected with the liquid, wherein the liquid can be pumped or conveyed by a reversible deformation of the section, and the liquid can be subsequently taken up via a sucking action, into the pump chamber by automatic returning of the section to an initial position, and an actuating element associated with a housing part acting on the section for the reversible deformation of the section from the initial position into a deformed state, wherein the section has a concave area in one or more of the initial position and in an unloaded state which can be pressed or deformed in order to pump the liquid into the pump chamber,wherein a thickness of the concave area of the dome-like section has a lesser wall thickness than a wall thickness of the dome-like section. 2. The dispensing device as set forth in claim 1, wherein a free end of the actuating element is flat or level or spherical. 3. The dispensing device as set forth in claim 1, wherein a diameter of the actuating element is less than 50% of a diameter of the pump chamber. 4. The dispensing device as set forth in claim 1, wherein the actuating element is tapered toward a free end. 5. The dispensing device as set forth in claim 4, wherein the actuating element is tapered uniformly, in the shape of a cone or truncated cone or truncated pyramid. 6. The dispensing device as set forth in claim 1, wherein one or more of: an end of the actuating element acting on the section and a bottom of the pump chamber arranged on a side facing away from the actuating element are complementary to each other, and the actuating element and the section are embodied such that the section fills out the pump chamber to greater than 90% in the deformed state. 7. The dispensing device as set forth in claim 1, wherein a force at least for an initial deformation of the section is less than 50 N. 8. The dispensing device of claim 1, wherein the liquid is a cosmetic liquid. 9. A dispensing device for dispensing a liquid comprising: a pump, with an elastically deformable or flexible, dome-like section which borders a pump chamber for the liquid or is fluidly connected with the liquid, wherein the liquid can be pumped or conveyed by a reversible deformation of the section, and the liquid can be subsequently taken up, via a sucking action, into the pump chamber by an automatic returning of the section to an initial position, and an actuating element associated with a housing part acting on the section for the reversible deformation of the section from the initial position into a deformed state, wherein the section has a flat or concave area in one or more of the initial position and in an unloaded state which can be pressed or deformed in order to pump the liquid into the pump chamber,wherein a pump bottom forms a recess into which the actuating element and the section are able to engage in the depressed state such that the section fills out the pump chamber to greater than 90%, andwherein a thickness of the flat or concave area has a lesser wall thickness than a wall thickness of the dome-like section. 10. The dispensing device as set forth in claim 9, wherein a free end of the actuating element is flat or level or spherical. 11. The dispensing device as set forth in claim 9, wherein a diameter of the actuating element is less than 50% of a diameter of the pump chamber. 12. The dispensing device as set forth in claim 9, wherein the actuating element is tapered toward a free end. 13. The dispensing device as set forth in claim 12, wherein the actuating element is tapered uniformly, in the shape of a cone or truncated cone or truncated pyramid. 14. The dispensing device as set forth in claim 9, wherein one or more of: an end of the actuating element acting on the section and a bottom of the pump chamber arranged on a side facing away from the actuating element are complementary to each other. 15. The dispensing device as set forth in claim 9, wherein a force at least for an initial deformation of the section is less than 50 N. 16. The dispensing device of claim 9, wherein the liquid is a cosmetic liquid. 17. A dispensing device for dispensing a liquid comprising: a pump, with an elastically deformable or flexible, dome-like section which borders a pump chamber for the liquid or is fluidly connected with the liquid, wherein the liquid can be pumped or conveyed by a reversible deformation of the section, and the liquid can be subsequently taken up, via a sucking action, into the pump chamber by an automatic returning of the section to an initial position and an actuating element associated with a housing part acting on the section for the reversible deformation of the section from the initial position into a deformed state, wherein a thickness of the dome-like section varies, such that the dome-like section has a greater wall thickness in a transitional area,wherein the transitional area is arranged in a middle of the section,wherein the transitional area is flat and level only on the outside,wherein the transitional area is thicker on the inside and has a greater wall thickness or ridgity than an adjoining wall of the section, andwherein the wall thickness of the transitional area is thickened toward where the transitional area is flat and level and toward the inside where there is an inwardly arching inner wall. 18. The dispensing device as set forth in claim 17, wherein the actuating element acts on or engages in the transitional area. 19. The dispensing device as set forth in claim 17, wherein the transitional area is preformed or molded in the section. 20. The dispensing device as set forth in claim 17, wherein the wall of the section adjoining the area or enclosing same in a ring-shaped configuration is arched, spherical, flatly spherical or convex.
