Abstract

A sponge is provided that can include an absorbent layer, a scrubbing layer, and a scrubbing enhancer. The absorbent layer can comprise cellulose. The scrubbing layer can be attached to a surface of the absorbent layer. The scrubbing layer can comprise a plant material and a synthetic material. The scrubbing enhancer can be at least partially disposed within an opening of the scrubbing layer. The scrubbing enhancer can form an at least partially enclosed area. The at least partially enclosed area can be configured to receive soap.

Claims

exact text as granted — not AI-modified
1 . A sponge comprising:
 an absorbent layer comprising a cellulose;   a scrubbing layer attached to a surface of the absorbent layer, the scrubbing layer comprising a blend of sisal and polyester; and   a plastic or silicone scrubbing enhancer comprising an opening within the scrubbing layer, wherein the absorbent layer is at least partially visible through the opening of the scrubbing layer.   
     
     
         2 . The sponge of  claim 1 , wherein the scrubbing enhancer is at least partially embedded within the absorbent layer. 
     
     
         3 . The sponge of  claim 1 , wherein the scrubbing enhancer rests on top of the absorbent layer. 
     
     
         4 . The sponge of  claim 1 , wherein the scrubbing enhancer is glued to the absorbent layer. 
     
     
         5 . The sponge of  claim 1 , wherein the scrubbing enhancer is glued to the scrubbing layer. 
     
     
         6 . The sponge of  claim 1 , wherein the scrubbing enhancer further comprises a flange configured to be positioned between the scrubbing layer and the absorbent layer. 
     
     
         7 . The sponge of  claim 1 , wherein the scrubbing layer is glued to the absorbent layer. 
     
     
         8 . The sponge of  claim 7 , wherein the glue is compostable. 
     
     
         9 . The sponge of  claim 1 , wherein the scrubbing layer is woven to the absorbent layer. 
     
     
         10 . The sponge of  claim 1 , wherein the scrubbing enhancer comprises polypropylene. 
     
     
         11 . The sponge of  claim 1 , wherein the scrubbing enhancer is ring shaped. 
     
     
         12 . The sponge of  claim 1 , wherein a top surface of the scrubbing enhancer extends beyond a top surface of the scrubbing layer. 
     
     
         13 . A sponge comprising:
 an absorbent layer comprising a cellulose;   a scrubbing layer attached to a surface of the absorbent layer, the scrubbing layer comprising a plant material and a synthetic material; and   a scrubbing enhancer at least partially disposed within an opening of the scrubbing layer, the scrubbing enhancer forming an at least partially enclosed area, the at least partially enclosed area configured to receive soap.   
     
     
         14 . The sponge of  claim 13 , wherein the scrubbing enhancer is at least partially embedded within the absorbent layer. 
     
     
         15 . The sponge of  claim 13 , wherein the scrubbing enhancer rests on top of the absorbent layer. 
     
     
         16 . The sponge of  claim 13 , wherein the scrubbing enhancer is glued to the absorbent layer. 
     
     
         17 . The sponge of  claim 13 , wherein the scrubbing enhancer is glued to the scrubbing layer. 
     
     
         18 . The sponge of  claim 13 , wherein the scrubbing enhancer further comprises a flange configured to be positioned between the scrubbing layer and the absorbent layer. 
     
     
         19 . The sponge of  claim 13 , wherein the scrubbing layer is glued to the absorbent layer. 
     
     
         20 . The sponge of  claim 19 , wherein the glue is compostable. 
     
     
         21 . The sponge of  claim 13 , wherein the scrubbing layer is woven to the absorbent layer. 
     
     
         22 . The sponge of  claim 13 , wherein the scrubbing enhancer comprises polypropylene. 
     
     
         23 . The sponge of  claim 13 , wherein the scrubbing enhancer is ring shaped. 
     
     
         24 . The sponge of  claim 13 , wherein the plant material of the scrubbing layer is sisal and the synthetic material of the scrubbing layer is polyester. 
     
     
         25 . The sponge of  claim 24 , wherein the scrubbing layer is about 60 percent sisal and about 40 percent polyester.
