Cleaning sponge

Abstract

A cleaning sponge with improved gripping for providing enhanced scouring and/or wiping ability is disclosed. In one embodiment, the cleaning sponge comprises a foam body having a side perimeter contained between a first surface and a second surface, a first outer layer of material attached to the first surface of the body, and a second outer layer of material attached to the second surface of the body. At least a portion of the side perimeter includes a recessed groove extending along a length of the foam body.

1 . A cleaning sponge comprising:
 a foam body having a side perimeter contained between a first surface and a second surface;   a first outer layer comprising a cellulose sponge attached to the first surface of the body;   a second outer layer of material attached to the second surface of the body;   wherein at least a portion of the side perimeter includes a recessed groove extending along a length of the foam body.   
   
   
       2 . The cleaning sponge of  claim 1 , wherein the foam body is hydrophobic. 
   
   
       3 . The cleaning sponge of  claim 1 , wherein the second outer layer is a scouring material. 
   
   
       4 . The cleaning sponge of  claim 3 , wherein the scouring material is selected from the group consisting of woven, knitted, nonwoven, foam and sponge any of which includes at least a partial resin coating. 
   
   
       5 . The cleaning sponge of  claim 1 , wherein the second outer layer is a wiping material. 
   
   
       6 . The cleaning sponge of  claim 1 , wherein the first outer layer is attached to the first surface of the body by a discontinuous coating of adhesive. 
   
   
       7 . The cleaning sponge of  claim 1 , wherein the recessed groove extends along opposite sides of the side perimeter. 
   
   
       8 . The cleaning sponge of  claim 1 , wherein the recessed groove extends along the entire side perimeter. 
   
   
       9 . The cleaning sponge of  claim 1 , wherein the body comprises at least a third of a thickness of the sponge. 
   
   
       10 . A cleaning sponge comprising:
 a scouring layer of material;   a cellulose sponge; and   a foam body having a side perimeter contained between a first surface and a second surface, opposite the first surface;   wherein the scouring layer of material is attached to the first surface of the foam body and the cellulose sponge is attached to the second surface of the foam body;   wherein at least a portion of the side perimeter of the foam body includes a recessed groove.   
   
   
       11 . The cleaning sponge of  claim 10 , wherein the scouring material is selected from the group consisting of woven, knitted, nonwoven, foam and sponge any of which includes at least a partial resin coating. 
   
   
       12 . The cleaning sponge of  claim 10 , wherein the recessed groove extends along opposite sides of the side perimeter. 
   
   
       13 . The cleaning sponge of  claim 10 , wherein the recessed groove extends along the entire side perimeter. 
   
   
       14 . The cleaning sponge of  claim 10 , wherein the foam body comprises at least a third of a thickness of the sponge. 
   
   
       15 . A cleaning sponge consisting of;
 a first scouring layer of material;   a second scouring layer of material; and   a foam body having a side perimeter contained between a first surface and a second surface, opposite the first surface;   wherein the first scouring layer of material is attached to the first surface of the foam body and the second scouring layer of material is attached to the second surface of the foam body;   wherein the side perimeter of the foam body includes recessed grooves.   
   
   
       16 . The sponge of  claim 15 , wherein the foam is cellulose sponge or polymeric foam. 
   
   
       17 . The sponge of  claim 15 , wherein the first and second scouring material are each independently selected from the group consisting of woven, knitted, nonwoven, foam and sponge any of which includes at least a partial resin coating. 
   
   
       18 . The sponge of  claim 15 , wherein at least one of the first or second scouring materials is melamine.
