The sponge is one of the oldest and most common Aids for cleaning purposes of various Art »It is not only used for body cleaning, for example as a bath sponge, but also for others Purposes, for example as a car sponge, dishwashing sponge, etc. used daily «

Sponges are known as natural sponges, as viscose or rubber sponges. Particularly recently, there has also been a move towards producing sponges from foam plastic, with polyurethane-based sponges made from foam plastic having a wide range of uses. have found _o Due to the manufacturing process for polyurethane foams, it is possible to

door and color deliberately so that from these Foam made sponges the natural sponges can be adjusted.

Foam plastics based on polyurethane are used in larger blocks from which the sponges are then cut out in the desired size »The blocks are available as angular cubes or rectangular columns or they have an oval or elongated shape with rounded ones Corners to give the sponge a better look «The edges of these blocks are through grinding operations Broken"

With all previously known plastic sponges you can always see that they are artificial products, because they have precise geometric shapes, making them look unwieldy and unnatural =

The task of the innovation is to make sponges out of foam plastic to create the opposite of known plastic sponges have better handiness through special design «, In order to achieve this goal, a sponge made of plastic, preferably based on polyurethane, according to the firing suggested that it have the external irregular shape of a natural sponge having. The handiness is mainly improved by the fact that the outer circumference of such a sponge is not is uniform and thus different diameters are given. The sponge made of foam plastic therefore has the size and above all the spatially irregular figure

of a natural sponge This new form of the plastic sponge is achieved by forming a goal and a corresponding rework "

In a preferred embodiment of the innovation, the pore structure of the sponge is at least on his Outside surface adapted to that of a natural sponge. When the pore structure is not that of a natural sponge due to the manufacturing process of the foam plastic it becomes the pore structure of a natural sponge through processing from the outside customized"

In the drawing, three exemplary embodiments are shown for the innovation produced sponges made of foam plastic shown, with Figures 1 to 3 each Represent top views of the various embodiments, while FIGS. 4 to 6 show cross-sections through the corresponding sponges are »In the cross-sections the pore structure of the individual sponges is only on the periphery, so that it can be seen that the pore structure is coarse and irregular, as in natural swarms is. Inside the sponges shown in the drawing, the pore structure can be any.
