Abstract
Abstract An improved cleaning-and washing-pad material, which pad material comprises in combination: a soft natural or synthetic shearling sheet material forming one surface of the pad material and a tough, nylon-mesh material forming the other surface of the pad, the shearling material and the nylon material sewed together about the peripheral edges to form a cavity therein; and a soft, resilient, substantially open-cell, polyurethane or cellulose sponge material loosely inserted within the hollow cavity to provide body and bulk to the pad, whereby the improved cleaning- and washing-pad material presents a soft water-absorbent surface for washing and a tough scrubbing surface for cleaning purposes.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
134 words
A cleaning-pad material, which pad material comprises in combination: (a) a soft natural or synthetic shearling material, having a fluffy, water-absorbing surface, forming one surface of the pad; (b) a tough, synthetic, mesh material forming the other surface of the pad; (c) the shearling material and the mesh material secured together about the peripheral edges of the shearling and mesh material to form a pad with an open end and a hollow cavity therein; and (d) a soft, resilient, cellular material comprising an open-cell, water-absorbing, foam material positioned within and substantially filling the hollow cavity to provide bulk and body to the pad, whereby the pad material presents a soft, water-absorbing, shearling surface for washing, and the mesh material presents a tough scrubbing surface for the removal of difficult-to-remove objects from a washing surface.
Claim 2
Dependent Claim
134 words
A cleaning-pad material, which pad material comprises in combination: (a) a soft natural or synthetic shearling material, having a fluffy, water-absorbing surface, forming one surface of the pad; (b) a tough, synthetic, mesh material forming the other surface of the pad; (c) the shearling material and the mesh material secured together about the peripheral edges of the shearling and mesh material to form a pad with an open end and a hollow cavity therein; and (d) a soft, resilient, cellular material comprising an open-cell, water-absorbing, foam material positioned within and substantially filling the hollow cavity to provide bulk and body to the pad, whereby the pad material presents a soft, water-absorbing, shearling surface for washing, and the mesh material presents a tough scrubbing surface for the removal of difficult-to-remove objects from a washing surface.
Claim 3
Dependent Claim
24 words
The pad material of claim 1 wherein the cellular material is a substantially open-cell, cellular material adapted to receive and to contain water therein.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
17 words
The pad material of claim 3 wherein the cellular material is positioned unsecured within the hollow cavity.
Claim 6
Dependent Claim
16 words
The pad material of claim 1 wherein the mesh material comprises a knitted, nylon, fabric material.
Claim 7
Dependent Claim
22 words
The pad material of claim 1 wherein the shearling material and the mesh material are secured by threads about the peripheral edges.
Claim 8
Dependent Claim
24 words
The pad material of claim 1 wherein the shearling material and the mesh material are secured by a water-insoluble adhesive about the peripheral edges.
Claim 9
Dependent Claim
40 words
The pad material of claim 1 wherein the pad has a surface area of about 2 square inches to 3 square feet or more and a height at its center of from about 1/2 inch to 2 inches or more.
Claim 10
Dependent Claim
131 words
A cleaning-pad material, which pad material comprises in combination: (a) a soft natural or synthetic shearling material, having a fluffy, water-absorbing surface, forming one surface of the pad; (b) a tough, knitted, synthetic, nylon-mesh material forming the other surface of the pad; (c) the shearling and the mesh material secured together by threads about all the peripheral edges of the shearling and mesh materials to form a hollow cavity therein; (d) a soft, resilient, cellular material, comprising an open-cell-, water-absorbing polyurethane foam material, positioned unsecured within and substantially filling the hollow cavity to provide bulk and body to the pad, whereby the pad material presents a soft, water-absorbing, shearling surface for washing, and the mesh material presents a tough scrubbing surface for the removal of difficult-to-remove objects from a washing surface.
Claim 11
Dependent Claim
131 words
A cleaning-pad material, which pad material comprises in combination: (a) a soft natural or synthetic shearling material, having a fluffy, water-absorbing surface, forming one surface of the pad; (b) a tough, knitted, synthetic, nylon-mesh material forming the other surface of the pad; (c) the shearling and the mesh material secured together by threads about all the peripheral edges of the shearling and mesh materials to form a hollow cavity therein; (d) a soft, resilient, cellular material, comprising an open-cell-, water-absorbing polyurethane foam material, positioned unsecured within and substantially filling the hollow cavity to provide bulk and body to the pad, whereby the pad material presents a soft, water-absorbing, shearling surface for washing, and the mesh material presents a tough scrubbing surface for the removal of difficult-to-remove objects from a washing surface.
Claim 12
Dependent Claim
36 words
The pad material of claim 1 wherein the open end of the pad material is secured along its peripheral edges to enclose fully the cellular material within the pad formed by the shearling and mesh material.
Claim 13
Independent Claim
70 words
A method of manufacturing a pad material for washing and cleaning surfaces, which method comprises: (a) securing together the peripheral edges of a natural or synthetic shearling material of predetermined size and a knitted, synthetic, fiber material to form a pouch-like container with one open end; and (b) inserting in the open end of the pouch-like container a soft, resilient, cellular sheet material to provide body to the pouch-like container.
