Abstract
Abstract A versatile cleansing article and reversible pillow-shaped scouring pad comprising a pair of layers of substrate material each having a strong abrasion surface and a 060264363 milder abrasion surface. The two layers are joined to each other along at least two edges and preferably along three edges thereof for enabling the pad to be reversed and to permit insertion of soap or detergent in the pillow.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
47 words
A cleansing article comprising a pair of superposed layers of material, each of said layers having a relatively rough abrasive surface and a mild abrasive surface, and means joining said layers to each other along at least two edges thereof for enabling said article to be reversed.
Claim 2
Dependent Claim
47 words
A cleansing article comprising a pair of superposed layers of material, each of said layers having a relatively rough abrasive surface and a mild abrasive surface, and means joining said layers to each other along at least two edges thereof for enabling said article to be reversed.
Claim 3
Dependent Claim
24 words
A reversible cleansing article according to claim 1, wherein each of said layers are fluid permeable, and wetting agent means disposed between said layers.
Claim 4
Dependent Claim
96 words
A reversible cleansing article comprising a pair of superposed layers of material, each of said layers being of a relatively rough abrasive material on the surfaces thereof remote from each other, each of said layers being of mild abrasive material on the surfaces thereof adjacent to each other, and means joining said layers to each other along at least two edges thereof for enabling said article to be reversed so that the surfaces having the substantially less rough coating are remote from each other and the surfaces having the relatively rough coating are adjacent each other.
Claim 5
Dependent Claim
96 words
A reversible cleansing article comprising a pair of superposed layers of material, each of said layers being of a relatively rough abrasive material on the surfaces thereof remote from each other, each of said layers being of mild abrasive material on the surfaces thereof adjacent to each other, and means joining said layers to each other along at least two edges thereof for enabling said article to be reversed so that the surfaces having the substantially less rough coating are remote from each other and the surfaces having the relatively rough coating are adjacent each other.
Claim 6
Dependent Claim
105 words
A reversible cleansing article comprising a pair of superposed layers of substrate material, each of said layers having a first coating of a relatively rough abrasive material on the surfaces thereof remote from each other, each of said layers having a second coating of substantially less rough abrasive material on the surfaces thereof adjacent to each other, and means joining said layers to each other along at least two edges thereof for enabling said article to be reversed so that the surfaces having the substantially less rough coating are remote from each other and the surfaces having the relatively rough coating are adjacent each other.
Claim 7
Dependent Claim
105 words
A reversible cleansing article comprising a pair of superposed layers of substrate material, each of said layers having a first coating of a relatively rough abrasive material on the surfaces thereof remote from each other, each of said layers having a second coating of substantially less rough abrasive material on the surfaces thereof adjacent to each other, and means joining said layers to each other along at least two edges thereof for enabling said article to be reversed so that the surfaces having the substantially less rough coating are remote from each other and the surfaces having the relatively rough coating are adjacent each other.
Claim 8
Dependent Claim
24 words
A reversible cleansing article according to claim 4, wherein each of said layers are fluid permeable, and wetting agent means disposed between said layers.
Claim 9
Dependent Claim
23 words
A reversible cleansing article according to claim 4, including means joining said layers to each other along three edges thereof forming a mitten.

A reversible cleansing article according to claim 7, wherein said second coating is selected from the group consisting of melamine resin, nylon, polypropylene, jeweler''s rouge.
Claim 12
Dependent Claim
18 words
A reversible cleansing article according to claim 4, wherein said substrate material is formed of a metallic substance.
Claim 13
Dependent Claim
17 words
A reversible cleansing article according to claim 4, wherein said substrate material is of a cellulosic substance.
Claim 14
Dependent Claim
18 words
