Claims

1. A brush head for applying a solid material, comprising:

an outer zone of bristles and an inner zone of recessed bristles, defining a reservoir;

wherein the inner zone of recessed bristles is convex in longitudinal cross section and the inner zone of recessed bristles is configured to retain a solid material for application to a surface.

2. The brush head of claim 1, wherein the inner zone of recessed bristles is rounded in longitudinal cross section.

3. The brush head of claim 1, wherein the outer zone of bristles has a flat surface defined by tips of the bristles.

4. The brush head of claim 1, wherein the outer zone of bristles comprises an outwardly tapered configuration.

5. The brush head of claim 1, wherein a circumferential shape of the outer zone of bristles in a transverse cross sectional view has a generally circular shape.

6. The brush head of claim 5, wherein a circumferential shape of the inner zone of recessed bristles in a transverse cross sectional view has a generally circular shape.

7. The brush head of claim 1, wherein the inner zone of recessed bristles comprises a greater pack density than that of the outer zone of bristles.

8. The brush head of claim 1, wherein a highest point of the inner zone of recessed bristles is below the height of the outer zone of bristles.

9. The brush head of claim 1, wherein the solid material is a powdered cosmetic.

10. The brush head of claim 1, wherein the solid material is a medicament.

27. A method of making a brush head of claim 1, comprising:

providing bristles;

arranging the bristles into an inner zone of recessed bristles and an outer zone of bristles;

forming the brush head of claim 1.

28. The method of making a brush head of claim 27, further comprising attaching the brush head to a handle.

29. The method of making a brush head of claim 27, further comprising securing the bristles within a crimping region, ring, or ferrule.

11. A system for applying a cosmetic using a brush head, comprising:

a brush head comprising an outer zone of bristles and an inner zone of recessed bristles, defining a reservoir;

wherein the inner zone of recessed bristles is convex in a longitudinal cross section and the inner zone of recessed bristles is configured to hold a cosmetic for application to a surface.

12. The system of claim 11, wherein the inner zone of bristles is rounded in longitudinal cross section.

13. The system of claim 11, further comprising a handle.

14. The system of claim 13, further comprising at least one crimping area, ring, or ferrule.

15. The system of claim 11, wherein the cosmetic is a powdered cosmetic.

16. The brush head of claim 11, wherein the cosmetic is a medicament.

17. A method of using a brush head for applying a cosmetic, comprising:

providing a brush head having an outer zone of bristles and an inner zone of recessed bristles, defining a reservoir, wherein the inner zone of recessed bristles is convex in a longitudinal cross section;

applying a cosmetic to the brush head, such that the brush head retains the cosmetic;

transferring the cosmetic to a surface.

18. The method of claim 17, wherein applying a cosmetic to the brush head comprises pressing the brush head into a cosmetic such that the cosmetic is held on top of and/or between the bristles of the inner zone of recessed bristles.

19. The method of claim 17, wherein transferring the cosmetic to a surface comprises pressing the brush head against the surface so as to place the cosmetic in contact with the surface.

20. The method of claim 19, wherein pressing the brush head against a surface comprises moving the brush head in a circular motion or a sweeping motion on the surface.

21. The method of claim 17, further comprising moving the outer zone of bristles against the surface so as to buff and/or smooth the cosmetic.

22. The method of claim 17, wherein the cosmetic is a powdered cosmetic.

23. The method of claim 17, wherein the cosmetic is a medicament.

24. A method of making a brush head, comprising:

providing bristles;

arranging the bristles into an inner zone of recessed bristles and an outer zone of bristles; and

forming a brush head comprising an outer zone of bristles and an inner zone of recessed bristles, defining a reservoir, wherein the inner zone of recessed bristles is convex in longitudinal cross section.

25. The method of claim 24, further comprising attaching the brush head to a handle.
