摘要

(US6491937) A disposable substantially dry foamable product is described including a water-insoluble substrate such as a flexible web, the substrate having first and second major surfaces, with a plurality of moguls spaced apart on the first major surface and a foamable composition deposited in major amounts on the second surface and a minor amount on the first surface.  A method for producing the product is also described which employs the moguls in juxtaposition to a guide roller to establish space between a surface of the roller and the first surface of the substrate.  Foamed composition is deposited onto the second surface which by seepage through apertures in the substrate allow a minor portion of the coating composition to deposit on the first surface of the substrate.

主权利要求

(US6491937) What is claimed is: 1.  A substantially dry cleansing product comprising: (i) a water insoluble substrate defined by juxtaposed first and second major surfaces, the first major surface being formed with a plurality of upwardly projecting moguls spaced apart from one another;  and (ii) a foamable composition comprising a lathering surfactant wherein more of the composition is deposited on the second major surface than on the first major surface of the substrate. 2. The product according to claim 1 wherein the mogul has a conical or donut shape. 3. The product according to claim 1 wherein the mogul is of a material different from material forming a web of a substrate. 4. The product according to claim 3 wherein the mogul is formed of an elastomeric material. 5. The product according to claim 1 wherein the mogul is donut shaped. 6. The product according to claim 1 wherein the substrate includes apertures of a size ranging from about 0.01 to 3 mm in a largest dimension, the apertures allowing communication between the first and second surfaces. 7. The product according to claim 1 wherein the moguls contain a colorant to distinguish them from other areas of the substrate. 8. The product according to claim 1 wherein from at least 50% up to about 99.9% by weight of the foamable composition is deposited onto the second surface and from less than 50% down to about 0.1% by weight of the foamable composition is deposited onto the first surface. 9. A method for producing a cleansing article which comprises an apertured water-insoluble substrate having first and second major surfaces opposite one another, the first major surface being formed with a plurality of spaced apart moguls, and the article delivering a foamable composition comprising a lathering surfactant, the method comprising: feeding the substrate onto a guide roller, the first major surface of the substrate being juxtaposed against a surface of the guide roller; applying the foamable composition to the second major surface of the substrate while the first major surface remains juxtaposed against the guide roller;  and allowing a minor amount of the applied foamable composition to transfer through the apertured substrate from the second to the first major surface. 10. A substantially dry cleansing product comprising: (i) a water insoluble substrate defined by juxtaposed first and second major surfaces, the first major surface being formed with a plurality of upwardly projecting moguls spaced apart from one another, the moguls being separated from one another at their center by a distance of about 0.2 to about 4 cm;  and (ii) a foamable composition comprising a lathering surfactant wherein more of the composition is deposited on the second major surface than on the first major surface of the substrate. 11. The product according to claim 1 wherein the substrate comprises a single layer.
