Abstract

A dispensing device for dispensing a preferably cosmetic fluid is proposed. The dispensing device has an elastically deformable section for pumping a fluid. Simple and easy actuation is made possible by the section having a concave region in the initial position and/or by the thickness of the section varying.

Claims

1. Dispensing device for dispensing a preferably cosmetic liquid, particularly a pump, with an elastically deformable or flexible, particularly at least substantially spherical or convex section which borders on a pump chamber for the liquid or is fluidly connected therewith, wherein liquid can be pumped or conveyed by means of reversible deformation of the section and liquid can be subsequently taken up, particularly sucked, into the pump chamber by means of the preferably automatic returning of the section to the initial position, and preferably with an actuating element acting on the section for the reversible deformation of the section from the initial position into the deformed state,

wherein the section has a flat or concave area in the initial position and/or in the unloaded state which can be pressed or deformed in order to pump the liquid into the pump chamber, and/or

that the thickness of the spherical section varies, namely the section has a greater or lesser wall thickness in a circumferential edge or transitional area.

2. Dispensing device as set forth in claim 1, wherein the area is arranged in the middle.

3. Dispensing device as set forth in claim 1, wherein the actuating element acts on or engages in the area.

4. Dispensing device as set forth in claim 1, wherein the area is preformed or molded in the section.

5. Dispensing device as set forth in claim 1, wherein the area is particularly designed to be flat and/or level only on the outside.

6. Dispensing device as set forth in claim 1, wherein the area is particularly thickened on the inside and/or has a greater wall thickness or rigidity than the adjoining wall of the section.

7. Dispensing device as set forth in claim 1, wherein the wall of the section adjoining the area or enclosing same in a ring-shaped fashion is substantially arched, spherical, flatly spherical or convex.

12. Dispensing device as set forth in claim 1, wherein the free end of the actuating element is at least substantially flat or level or spherical.

13. Dispensing device as set forth in claim 1, wherein the diameter of the actuating element is less than 50% of the diameter of the pump chamber.

14. Dispensing device as set forth in claim 1, wherein actuating element is tapered toward the free end.

15. Dispensing device as set forth in claim 14, wherein the actuating element is tapered at least substantially uniformly, preferably in the shape of a cone or truncated cone or truncated pyramid.

16. Dispensing device as set forth in claim 1, wherein the end of the actuating element acting on the section and the bottom of the pump chamber arranged on the side facing away from the actuating element are designed to be at least substantially complementary to each other and/or wherein 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.

17. Dispensing device as set forth in claim 1, wherein the force at least for the initial deformation of the section is less than 50 N.

8. Dispensing device for dispensing a preferably cosmetic liquid, particularly a pump, with an elastically deformable or flexible, particularly at least substantially spherical or convex section which borders on a pump chamber for the liquid or is fluidly connected therewith, wherein liquid can be pumped or conveyed by means of reversible deformation of the section and liquid can be subsequently taken up, particularly sucked, into the pump chamber by means of the preferably automatic returning of the section to the initial position, and with an actuating element acting on the section for the reversible deformation of the section from the initial position,

wherein the end of the actuating element acting on the section and the bottom of the pump chamber arranged on the side facing away from the actuating element are designed to be least substantially complementary to each other and/or

wherein the actuating element and the spherical section are embodied such that the section fills out the pump chamber to greater than 70% in the deformed state.

9. Dispensing device as set forth in claim 8, wherein the section fills out the pump chamber to greater than 90%, particularly greater than 95%, in the deformed state.

18. Dispensing device as set forth in claim 8, wherein the free end (20) of the actuating element is at least substantially flat or level or convex.

19. Dispensing device as set forth in claim 8, wherein the diameter of the actuating element is less than 50% of the diameter of the pump chamber.

20. Dispensing device as set forth in claim 8, wherein the actuating element is tapered at least substantially uniformly, preferably in the shape of a cone or truncated cone or truncated pyramid.

10. Dispensing device for dispensing a preferably cosmetic liquid, particularly a pump, with an elastically deformable or flexible, at least substantially spherical or convex section which borders on a pump chamber for the liquid or is fluidly connected therewith, wherein liquid can be pumped or conveyed by means of reversible deformation of the section and liquid can be subsequently taken up, particularly sucked, into the pump chamber by means of the preferably automatic returning of the section to the initial position, and preferably with an actuating element acting on the section for the reversible deformation of the section from the initial position into the deformed state, wherein the force at least for the initial deformation of the section is less than 50 N.

11. Dispensing device as set forth in claim 10, wherein the force for the deformation of the section is less than 30 N, particularly less than 20 N.
