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 method of cleaning the skin comprising:
(i) providing a skin cleaning article
a. said article having a maximum diameter of between about 5 cm and about 15 cm and having at least first and second layers,
b. said first layer having first and second opposed surfaces and further having a plurality of discrete apertures extending there through and individually having an area between 8 mm 2 and 700 mm 2 ,
c. the first layer includes first and second regions, said first and second regions each comprising between 25% and 50% of the first layer and wherein a pattern of apertures is located in each of said first and second regions and further wherein the pattern of apertures within said first and second regions are distinct from one another,
d. wherein the apertures in the first region comprise between 5-65% of the first region and the apertures of the second region comprise between 5-45% of the second region and further wherein apertures in the first region occupy at least 15% more area than the apertures of the second region,
e. said second layer having first and second opposed surfaces wherein the first surface of the second layer has a rougher hand feel than the outer surface of the first layer,
f. wherein the first surface of the second layer is adjacent the second surface of the first layer and further wherein said first surface of said second layer is exposed via the apertures in the first layer and in a recessed position relative to the first surface of the first layer;

(ii) applying water or cleansers to the article thereby forming a wetted article; and then
(iii) pressing and rubbing the first side of the first layer against the skin wherein the recessed first surface of the second layer directly contacts the skin through the apertures and cleans the skin.

2. The method of claim 1 wherein the apertures within the first layer have a plurality of different sizes such that selected individual apertures in the first region are at least 20% larger by area than selected apertures in the second region.

3. The method of claim 2 wherein the apertures within the first region have (i) a minimum diameter of 4 mm and a maximum diameter of 20 mm and (ii) an area of between 12 mm 2 and 300 mm 2 .

4. The method of claim 1 wherein the first layer comprises a fibrous material having an average fiber diameter of less than about 50 microns and further wherein the first surface of said second layer comprises a material having polymeric protuberances thereon, said protuberances having an average diameter between about 75 microns and about 1000 microns and a hardness of between 65 and 100 as measured according to ASTM D2240 (Type D).

5. The method of claim 4 wherein the protuberances comprise a polymeric material having a hardness between 65 and about 90 as measured according to ASTM D2240 (Type D) and further having a flexural modulus of at least 500 MPa.

6. The method of claim 1 wherein the first layer comprises a fibrous material having an average fiber diameter of less than about 50 microns and a basis weight between about 50-175 g/M 2 and further wherein the first surface of the second layer has yarns or fibers exposed thereon that have an average diameter of between about 75 microns and about 2000 microns.

7. The method of claim 1 wherein the average edge-to-edge distance between adjacent apertures is smaller in the first region relative to the second region.

8. The method of claim 1 wherein the first region has a greater number of apertures per unit area than the second region.

9. The method of claim 1 wherein the first and second regions are concentrically located relative to one another.

10. The method of claim 1 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.

11. The method of claim 10 wherein the first and second regions each comprise about 50% of the first layer.

12. The method of claim 1 wherein said article further includes a third layer and wherein the first and third layers are joined at the periphery of the article and wherein the second layer is located between the first and third layers.

13. The method of claim 12 wherein said article further includes a fourth layer located between said second and third layers and wherein said fourth layer comprises a resiliently-deformable porous material.

14. The method of claim 1 wherein an inner portion of the article includes a skin cleaning composition comprising a lathering surfactant, a humectant and a moisturizing agent.

15. The method 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.

16. The method of claim 1 wherein the article has a curvilinear shape and a diameter between about 5 cm and about 10 cm.

17. A method of cleaning the skin comprising:
(i) providing a skin cleaning article
a. said article having a maximum diameter of between about 5 cm and about 15 cm and having at least first and second layers,
b. said first layer having first and second opposed surfaces and further having a plurality of discrete apertures extending there through and individually having an area between 8 mm 2 and 700 mm 2 ,
c. the first layer includes first and second regions, said first and second regions each comprising between 25% and 50% of the first layer and wherein a pattern of apertures is located in each of said first and second regions and further wherein the pattern of apertures within said first and second regions are distinct from one another,
d. wherein the apertures in the first region have a larger average size, by area, than that of the apertures in the second region,
e. said second layer having first and second opposed surfaces wherein the first surface of the second layer has a rougher hand feel than the outer surface of the first layer,
f. wherein the first surface of the second layer is adjacent the second surface of the first layer and further wherein said first surface of said second layer is exposed via the apertures in the first layer and in a recessed position relative to the first surface of the first layer;

(ii) applying water or cleansers to the article thereby forming a wetted article; and then
(iii) pressing and rubbing the first side of the first layer against the skin wherein the recessed first surface of the second layer directly contacts the skin through the apertures and cleans the skin.

18. The method of claim 17 wherein the first layer comprises a compressible nonwoven web having a basis weight between about 50 to 175 g/M 2 and further comprises a fibrous material having an average fiber diameter of less than about 50 microns, and further wherein the first surface of said second layer comprises a material having polymeric protuberances thereon, said protuberances having an average diameter between about 75 microns and about 1000 microns and a hardness of between 65 and 100 as measured according to ASTM D2240 (Type D) and a flexural modulas greater than about 500 MPa.

19. The method of claim 17 wherein the first layer comprises a compressible nonwoven web having a basis weight between about 50 to 175 g/M 2 and further comprises a fibrous material having an average fiber diameter of less than about 50 microns, and further wherein the first surface of the second layer has yarns or fibers exposed thereon that have an average diameter of between about 75 microns and about 2000 microns.
