Scrub sponge with selectively accessible abrasive region
View Patent ↗The present invention is a new type of scrub sponge which includes a soft sponge portion and an abrasive pad. According to one embodiment of the invention, the abrasive pad is bonded to the sponge in a recess formed in the sponge so that during normal use, only the surface of the soft sponge will contact the surface of the item being cleaned. Should, during cleaning, the user require a more aggressive scrubbing action, the user may press into the upper side of the soft sponge on an upper side to force the abrasive pad out from its protective recess on the opposing side. The now protruding abrasive pad will contact the surface of the item being cleaned. The action of pushing out the abrasive pad is intuitive to the user since the user will typically push hard on any cleaning implement when they need more aggressive scrubbing action. With the present invention, as the user pushes hard, the more abrasive pad will reveal itself and offer its scrubbing texture to help in the cleaning process.
1. A scrub sponge for selectively cleaning a working surface by a user, said sponge comprising:
a substrate made from a first flexible material and defining a top surface and an opposing bottom surface;
a recess formed within said bottom surface of said substrate, said recess having a first shape and a first depth and defining a recessed surface;
a layer of a second material located within said recess and secured to said recessed surface, said second material having a first level of abrasive texture, said layer having a magnitude of thickness that is less than the magnitude of said first depth of said recess so that said second material resides within said first substrate, with respect to said bottom surface of said substrate; and
wherein said second material extends beyond said bottom surface of said substrate in response to selective deformation of said substrate by said user so that said second material with said first level of abrasive texture can be selectively accessed to clean said working surface by said user.
2. The scrub sponge, according to claim 1 , wherein said first material includes a second level of abrasive texture and wherein said second level of abrasive texture is greater than said first level of abrasive texture.
3. The scrub sponge, according to claim 1 , wherein said first material includes a second level of abrasive texture and wherein said first level of abrasive texture is greater than said second level of abrasive texture.
4. The scrub sponge, according to claim 1 , wherein said layer of said second abrasive texture includes a support material which is bonded to said recess surface.
5. The scrub sponge, according to claim 4 , wherein the shape of said support material is substantially similar to said first shape of said recess.
6. The scrub sponge, according to claim 1 , wherein said first shape of said recess is generally circular.
7. The scrub sponge, according to claim 1 , wherein said first shape of said recess is generally rectangular.
