## Abstract

The invention is directed to a scrubber/scraper sponge. The sponge is comprised of three layers. A lower sponge layer provides a soft, absorbent washing surface on the bottom surface of the sponge. An upper abrasive layer provides a scrubbing surface on the top surface of the sponge. The front peripheral edge of the sponge provides a scraping edge on a scraping layer, which extends partially from the front edge toward the rear edge of the sponge, between the sponge layer and the abrasive layer. Flexible barbs extend rearward from the rear edge of the scraping layer, such that the barbs become embedded in the sponge layer during the manufacturing process and firmly secure the scraping layer to the sponge layer.

## Claims

### Claim 1

A scrubber/scraper sponge which provide three layers, comprising:
a lower sponge layer which provides a soft, absorbent washing surface on a bottom surface of the sponge;
an upper abrasive layer which provides a scrubbing surface on a top surface of the sponge;
a scraping layer which is positioned at least partially in between the lower sponge layer and the upper abrasive layer, the scraping layer having a rear edge positioned between the lower sponge layer and the upper abrasive layer and the front edge extending outward from the sponge, in which the scraping layer tapers from the rear edge in between the lower sponge layer and the upper abrasive layer to the front edge of the scraping layer; and
extensions that are secured to and which extend from the rear edge of the scraping layer, wherein each extension includes barbs that embed in at least the lower sponge layer to secure the scraping layer to the sponge, in which the extensions and barbs are positioned between the lower sponge layer and the upper abrasive layer.

### Claim 2 (depends on 1)

The scrubber/scraper sponge of claim 1, wherein the front edge of the scraping layer protrudes from a front peripheral edge of the sponge.

### Claim 3 (depends on 1)

The scrubber/scraper sponge of claim 1, wherein the scraping layer provides a scraping edge on the front edge.

### Claim 4 (depends on 1)

The scrubber/scraper sponge of claim 1, wherein the upper abrasive layer, scraping layer, and lower sponge layer are further secured together by application of an adhesive during the manufacturing process.

### Claim 5 (depends on 1)

The scrubber/scraper sponge of claim 1, wherein the sponge layer is comprised of a flexible, durable, and absorbent material.

### Claim 6 (depends on 1)

The scrubber/scraper sponge of claim 1, wherein the abrasive layer is comprised of a flexible, durable, and abrasive material.

### Claim 7 (depends on 1)

The scrubber/scraper sponge of claim 1, wherein the scraping layer is comprised of a flexible and durable material.
