Abstract

The present invention provides personal cleaning articles useful for cleaning and/or exfoliating the skin. These articles provide multiple distinct patterns of relatively smooth and coarse elements to provide a user the ability to readily achieve the desired degree of cleansing and/or exfoliation. Further, the article provides a relatively smooth apertured outer layer and a relatively coarse underlying layer whereby a user can, with the application of varied amounts of pressure, more readily achieve and control a wider range of mechanical cleaning and/or exfoliating action against the skin. In certain aspects, the article may also be impregnated with one or more topical skin cleaning and/or exfoliating compounds.

First claim

What is claimed is:

1. A personal care skin treatment article comprising:
opposed first and second sides, said first side defined at least in part by a first layer and said second side defined at least in part by a second layer;
said first side having a first region and a second region;
said first region of the first side having a pattern of interposed low texture portions and recessed high texture portions wherein the high texture portions comprise between about 5-65% of the total surface area of the first region;
said second region of the first side having a pattern of interposed low texture portions and recessed high texture portions and wherein (i) the high texture portions comprise between about 5-45% of the total surface area of the second region, (ii) the ratio of the surface area of the high texture portions of the first region to the surface area of the high texture portions of the second region is not less than 1.15:1, and (iii) the high texture portions of the first region have a larger average size, by area, than the average size of the high texture portions in the second region.

2. The personal care article of claim 1 wherein the high texture portions of the first region include a greater number of high texture portions than that contained within the second region.

3. The personal care article of claim 1 wherein the high texture portions of the first region form a cluster and the high texture portions of the second region form a cluster and further wherein the average edge-to-edge distance between adjacent high texture portions is smaller in the first region relative to that in the second region.

4. The personal care article of claim 1 wherein the first region and second region are separated by a third region and further wherein the third region lacks high texture portions.

5. The personal care article of claim 1 wherein the first and second regions are concentrically located relative to one another.

6. The personal care article of claim 1 wherein the first and second regions are either (i) defined by a diameter line whereby the first and second regions each comprise about 50% of the first side or (ii) defined by radius lines and whereby the first and second regions each comprise between about 25% and about 50% of the first side.

7. The personal care article of claim 1 wherein one or more layers of the article include a skin cleaning composition comprising a lathering surfactant, a humectant and a moisturizing agent.

8. The personal care article of claim 7 wherein the cleaning article has a maximum diameter of between about 5 cm and about 15 cm.

9. The personal care article of claim 8 further including a third layer and wherein the first and third layers are joined at the periphery of the article and further wherein the second layer is located between the first and third layers.

10. The personal care article of claim 9 further including a fourth layer located between said second and third layers and wherein said fourth layer comprises a resiliently-deformable porous material.

11. The personal care article of claim 1
wherein the first layer comprises a compressible nonwoven web having a basis weight between about 50 to 175 g/M 2 and an average fiber diameter less than about 50 microns; and
further wherein the second layer comprises a material having protuberances thereon adjacent the first layer, and the protuberances have an average diameter between about 75 microns and about 2000 microns.

12. A personal care skin treatment article comprising:
opposed first and second sides, said first side defined at least in part by a first layer and said second side defined at least in part by a second layer;
said first side having a pattern of interposed high texture portions and low texture portions wherein the high texture portions comprise between about 5-65% of the total surface area of the first side;
wherein the high texture portions have a minimum diameter not less than 3 mm and maximum diameter not greater than 30 mm;
wherein the high texture portions have a plurality of different sizes such that selected individual high texture portions are at least 20% larger by area than other selected high texture portions; and
further wherein the individual size by area of the individual high texture portions decreases radially.

13. The personal care article of claim 12 wherein the high texture portions are discretely located and sized such that they have an area between 8 mm 2 and 700 mm 2 and further wherein the recessed high texture portions are located entirely below the outer surface of the surrounding low texture portion.

14. The personal care article of claim 12 wherein the article has a circular shape and further wherein the article has a maximum diameter of between about 5 cm and about 15 cm.

15. The personal care article of claim 12 wherein one or more layers of the article include a skin cleaning composition comprising a lathering surfactant, a humectant and a moisturizing agent.

16. A personal care skin treatment article comprising:
a first layer having an inner and outer surface and further having plurality of apertures each defining an area of not less than 8 mm 2 ;
the first side includes first and second regions, said first and second regions comprising between 25% and 50% of the first side and wherein each of said first and second regions include a distinct pattern of apertures and further wherein the apertures in the first region have a larger average size, by area, than the average size of the apertures in the second region;
a second layer superposed with and adjacent the inner surface of the first layer whereby said second layer is physically contactable via the apertures in said first layer; and
wherein the surface of the second layer adjacent the first layer has a rougher hand feel than the outer surface of the first layer.

17. The personal care article of claim 16 wherein the apertures comprise between about 5-65% of the outer surface of the first layer.

18. The personal care article of claim 16 wherein the apertures comprise between about 5-45% of the outer surface of the first layer.

19. The personal care article of claim 16 wherein the individual apertures have minimum diameters not less than 3 mm and maximum diameters not greater than 30 mm and an area between about 12 mm 2 and 300 mm 2 .

20. The personal care article of claim 16 wherein the apertures of the first region include a greater number of apertures than that contained within the second region.

21. The personal care article of claim 16 wherein the average edge-to-edge distance between adjacent apertures is smaller in the first region relative to the second region.

22. The personal care article of claim 16 wherein the first and second regions are concentrically located relative to one another.

23. The personal care article of claim 16 wherein the first and second regions are separated by a diameter line lacking any apertures and having a width of at least about 5 mm.

24. The personal care article of claim 16 wherein the first and second regions each comprise about 50% of the first layer.

25. The personal care article of claim 16 wherein the second layer comprises a material having protuberances thereon adjacent the first layer, and wherein the protuberances have an average diameter between about 75 microns and about 1000 microns.

26. The personal care article of claim 16 further co
