Plastic sponge.

The innovation relates to a plastic sponge, in particular used to clean a smooth surface.

When washing a smooth surface such as the windshield or the body of a motor vehicle, the plastic sponge often tends to surface to cling to. This is caused by the pressure exerted on the plastic sponge closing the pores and in this way the supply of liquid to the surface to be cleaned is interrupted.

The object of the innovation is therefore a plastic that floated; easier to clean on a smooth surface ϊ moves than an ordinary plastic sponge. : |

The distinguishing feature of the plastic sponge according to The innovation is that a number of recesses is formed on at least one side, which relative to the Pores of the sponge are relatively large, so that when Pressing this side against a smooth surface increased supply of cleaning fluid from the sponge to the surface takes place, thereby reducing the friction between the sponge and the surface.

Preferably, the sponge is substantially rectangular in shape and is provided with a groove on each of the two opposite sides so that the sponge can be more easily held by hand without slipping out, the grooves protecting the fingers and fingers when the sponge is in use Offer fingernails.

In a sponge of a size suitable for holding by hand, preferably 3-9 recesses should be provided for the best effectiveness of the sponge .

The recesses can expediently be on one or both | Sides of the sponge with the greatest surface area be educated.

In the figures of the drawing, a sponge 11 is shown of a substantially rectangular shape.

The sponge is made of plastic, such as foam rubber or plastic foam, and has a cell-like structure of pores 12. Only a small number of the pores 12 are shown in the drawing. A _u f one side of the sponge recesses 13 or grooves 15 are formed,

which are of such a size that they can feed the Allow cleaning fluid on a smooth surface to be cleaned when the pressure exerted on the sponge is so great is that the liquid cannot easily leak out of the pores. With the known sponges the was in contact with The surface area to be cleaned located on the sponge is not sufficiently wetted with cleaning liquid and the sponge therefore showed a tendency to get stuck. If, according to the innovation, pressure is applied to the sponge in use Sponge is exercised, the liquid comes out of the recesses 15 or grooves 15 and the sponge slides slightly over a glossy surface.

Along each of the two longitudinally extending sides, a JTut 14 is formed which enables that the sponge can be held by hand more easily without slipping out, and which when using the sponge the Protects fingers and fingernails from abrasions or cuts.

Recesses corresponding to the recesses 13 or 15 grooves can also be formed on any other side of the sponge to be used for cleaning.
