Abstract

A multi-layer sponge assembly is disclosed which contains a metallic disk that mates with a separate metallic element to allow the sponge to be elevated in a suspended position to dry.

Claims (39)

1. A sponge, comprising:

a first material having a first material property;

a second material having a second material property; and

a magnetic disk connecting to the first material and to the second material, the magnetic disk having a spool-shaped configuration with a top portion, a bottom portion, and a central portion.

2. The sponge of claim 1 , further comprising a magnetic element that magnetically attaches to the magnetic disk in order to secure the sponge to a surface.

3. The sponge of claim 2 , wherein the magnetic disk contains a ferromagnetic metal and the magnetic element contains a magnet.

4. The sponge of claim 1 , wherein the first material and the second material are layered upon each other and share a complete external peripheral edge.

5. The sponge of claim 4 , wherein the external peripheral edge of the first material and the second material is sealed with a seam.

6. The sponge of claim 1 , wherein at least the first material or the second material includes transverse seams that span across an external surface of the first or second material.

7. The sponge of claim 1 , wherein the first material has a different thickness than the second material.

8. The sponge of claim 1 , wherein the first material has a different absorbency than the second material.

9. The sponge of claim 1 , wherein the first material has a different tear strength than the second material.

10. The sponge of claim 1 , wherein the top portion and the bottom portion of the magnetic disk is within an area defined by an exterior surface of the first material and an exterior surface of the second material.

11. The sponge of claim 1 , wherein at least the top portion or the bottom portion of the magnetic disk includes projections.

12. The sponge of claim 11 , wherein the magnetic disk is positioned centrally within the first material and the second material such that its top portion is adjacent to an exterior surface of the first material and its bottom portion is adjacent to an exterior surface of the second material.

13. The sponge of claim 12 , wherein a height of the magnetic disk as measured from its top portion to its bottom portion is less than a thickness of the first material and the second material layered upon each other.

14. The sponge of claim 13 , wherein, in use, the first material and the second material may be bent such that the bottom portion of the magnetic disk may be pushed to extend into a plane defined by the exterior surface of the second material.

15. A sponge, comprising:

a first material having a first material property;

a second material having a second material property; and

a magnetic disk connecting to the first material and to the second material,

wherein the magnetic disk contains two components which are connected together through snap fit.

16. A sponge, comprising:

a first material having a first material property;

a second material having a second material property; and

a magnetic disk connecting to the first material and to the second material,

wherein the magnetic disk contains two components which are connected together by a threaded mechanism.

17. A sponge, comprising:

a first material having a first material property;

a second material having a second material property, and completely layered upon the first material such that they have a thickness and share a single peripheral edge; and

a spool-shaped magnetic disk having a top surface and a bottom surface that connects to the first material and to the second material, such that a distance from the top surface to the bottom surface is less than the thickness of the first material layered upon the second material.

18. The sponge of claim 17 , wherein the magnetic disk magnetically attaches to a magnetic element in order to suspend the sponge from a surface.

19. A sponge assembly, comprising:

a sponge comprising:

a first material having a first material property;

a second material having a second material property; and

a magnetic disk having a spool-shaped configuration with a top portion, a bottom portion, and a central portion, and is positioned to connect with the first material and with the second material; and

a magnetic element, which secures the magnetic disk to a surface.

20. The sponge assembly of claim 19 , wherein the magnetic disk is positioned centrally within the first material and the second material such that its top portion is adjacent to an outer surface of the first material and its bottom portion is adjacent to an outer surface of the second material.
