MULTI-LAYER MELAMINE SPONGE

Abstract

According to an aspect of the present invention, there is provided melamine sponge, comprising: a first outer melamine layer; a middle scrubbing layer; and a second outer melamine layer separated from the first outer melamine layer by the middle scrubbing layer.

Claims

1. A melamine sponge, comprising: a first outer melamine layer; a middle scrubbing layer; and a second outer melamine layer separated from the first outer melamine layer by the middle scrubbing layer.

2. The melamine sponge of claim 1, wherein the first outer melamine layer and the second outer melamine layer are identical.

3. The melamine sponge of claim 1, wherein the melamine sponge is square in shape.

4. The melamine sponge of claim 1, wherein one or more of the melamine layers are abradable melamine foam.

5. The melamine sponge of claim 1, wherein the middle scrubbing layer is made of polyurethane.

6. A method of using a melamine sponge, comprising: applying pressure to a first outer melamine layer to press a second outer melamine layer separated from the first outer melamine layer by a scrubbing layer against a surface; releasing the second outer melamine layer from the surface; and pressing the scrubbing layer against the surface.

7. The method of using a melamine sponge of claim 6, wherein the surface is a shoe.

8. The method of using a melamine sponge of claim 6, wherein the surface is a wall.

9. The method of using a melamine sponge of claim 6, wherein the surface is a floor.

DETAILED DESCRIPTION

[0011] The present invention comprises a scrubbing layer sandwiched between outer melamine foam layers.

[0012] The scrubbing layer can be for example a urethane abrasive sponge layer made of polyurethane. In other embodiments, the scrubbing layer could also be made of polyester, nylon or vegetable cellulose, among other compositions.

[0013] The melamine foam is preferably an abradable melamine foam which disintegrates or wears away during use. Melamine foam can be for example Basotect, a flexible, open-cell foam made from melamine resin. A typical characteristic is the intricate spatial mesh structure that is formed by thin ribs that can therefore be bent into shape easily. The melamine foam can be an open cell foam that is microporous and extremely hard so that when rubbed on a surface for cleaning it works like extremely fine sandpaper.

[0014] Other types of melamine foam can be used as well.

[0015] FIG. 1 illustrates a perspective view of a multi-layer melamine sponge according to the present invention.

[0016] The melamine sponge consists of outer melamine layers 10 and scrubbing layer 12, as described above. The outer melamine layers 10 may be identical, or one of the layers may be different from the other, for example, thicker.

[0017] FIG. 2 illustrates an end of the multi-layer melamine sponge according to the present invention.

[0018] The outer melamine layer 10 has protrusions which are illustrated as being hexagonal shaped but any other suitable shape can alternatively be utilized.

[0019] FIG. 3 illustrates a side view of the multi-layer melamine sponge according to the present invention.

[0020] Scrubbing layer 12 is exposed on the sides of the multi-layer melamine sponge between the melamine layers 10. Scrubbing layer 12 can be used to clean a surface by applying the side of the multi-layer melamine sponge to the surface.

[0021] Scrubbing layer 12 also improves the durability and toughness of cleaning by the top and bottom of the melamine sponge even when the scrubbing layer is not directly is use with the side of the melamine sponge against a surface.
