Abstract

An applicator device comprising a main head having a surface bearing protrusion elements of specified dimensional character. The disclosed device has superior utility for the application to the skin of materials such as skin lotions, tanning oils, salves, massage oils, depilatory creams, shaving creams and gels, personal lubricants, and the like.

Claims

1. An applicator device comprising a main head defining a planar applicator face comprising an array of uniformly sized and uniformly shaped protrusion surface portions thereon, wherein the protrusion surface portions are surrounded by planar surface portions of the applicator face, wherein the protrusion surface portions are of convex character protruding upwardly from the applicator face and have a diameter of from about 0.5 to about 1.5 cm, a height measured from the planar face of from about 0.05 to about 0.2 cm, a height-to-diameter ratio of from about 0.03 to about 0.40, and a protrusion surface portion density of from about 1 to about 3 surface protrusion portions/cm².

2. An applicator device according to claim 1, wherein the protrusion surface portions are of partial spherical shape.

3. An applicator device according to claim 1, wherein the protrusion surface portions are positioned in holes formed in the main head applicator face and are formed of cured swelled material defining bumps as the protrusion surface portions.

4. An applicator device according to claim 1, wherein the protrusion surface portions have a diameter of from about 0.6 to about 1.2 cm, a height of from about 0.05 to about 0.15 cm, and a density of from about 1.25 to about 2.5 protrusion surface portions/cm².

5. An applicator device according to claim 1, wherein the protrusion surface portions have a diameter of from about 0.7 to about 1.0 cm, a height of from about 0.05 to about 0.10 cm, and a density of from about 1.5 to about 2.0 protrusion surface portions/cm².

6. An applicator device according to claim 1, wherein the applicator face has a surface area of from about 25 to about 150 cm².

7. An applicator device according to claim 1, wherein the applicator face has a surface area of from about 40 to about 120 cm².

8. An applicator device according to claim 1, wherein the applicator face has a surface area of from about 50 to about 100 cm².

9. An applicator device according to claim 1, further comprising a handle secured to the main head.

10. An applicator device according to claim 9, wherein the handle has length of from about 10 to about 40 cm.

11. An applicator device according to claim 9, wherein the handle has length of from about 15 to about 25 cm.

12. An applicator device according to claim 9, wherein the handle has length of from about 20 to about 30 cm.

13. An applicator device according to claim 1, formed of a material of construction selected from those of the group consisting of:

plastics;

polymeric materials;

metals;

ceramics;

wood;

composite materials; and

combinations thereof.

14. An applicator device according to claim 1, wherein the main head is integrally secured to a handle member of manually graspable size and shape, and the handle and main head are integrally formed as a single-piece article.

15. An applicator device according to claim 14, wherein the device has been formed by injection molding.

16. An applicator device comprising a main head defining a planar applicator face comprising an array of uniformly sized and uniformly shaped protrusion surface portions thereon, wherein the protrusion surface portions are surrounded by planar surface portions of the applicator face, wherein the protrusion surface portions are of convex character protruding upwardly from the applicator face and have a diameter of from about 0.6 to about 1.2 cm, a height measured from the planar face of from about 0.05 to about 0.20 cm, a height-to-diameter ratio of from about 0.04 to about 0.33, and a protrusion surface portion density of from about 1.25 to about 2.5 surface protrusion portions/cm².

17. An applicator device comprising a main head defining a planar applicator face comprising an array of uniformly sized and uniformly shaped protrusion surface portions thereon, wherein the protrusion surface portions are surrounded by planar surface portions of the applicator face, wherein the protrusion surface portions are of convex character protruding upwardly from the applicator face and have a diameter of from about 0.7 to about 1.0 cm, a height measured from the planar face of from about 0.05 to about 0.15 cm, a height-to-diameter ratio of from about 0.05 to about 0.21 and a protrusion surface portion density of from about 1.5 to about 2.0 surface protrusion portion/cm².
