Abstract

1. A scrubber sponge, comprising a gripping part (2) of soft polyurethane foam having a scrubbing part (1) of coarse non-woven material optionally containing an abrasive connected to it, and a cleansing agent (4), such as soap, a solid cleansing agent paste or the like, which is inserted at different points between the polyurethane foam and the scrubbing part and is covered by a water-impermeable film (3) or an appropriately cut layer of plastic or a plastic container, characterized in that the film (3) or the layer of plastic or the plastic container covers the cleansing agent (4) in such a manner that it is sealed off only from the gripping part (2), and in that the scrubbing part (1) of coarse non-woven material optionally containing an abrasive is connected to the gripping part (2) by foam penetration.

Scouring pad

The innovation concerns a scouring sponge, consisting of a handle made of u / calibrated foam and an abrasive part made of coarse nonwoven fabric, optionally containing abrasives, with a cleaning agent, in particular Soap »is provided.

-Z-

Scouring sponges of this type are known. They consist of an abrasive part made of coarse nonwoven fabric made of synthetic fibers, optionally containing abrasives, and a sponge layer made of polyurethane foam, viscose or eehwamin-like nonwoven fabric. Seheuerachvämnte made of polyurethane and Viakoae are particularly popular and are mainly used as pan cleaners or bathroom cleaners.

The sponge part and the scrubbing are usually produced by gluing the pre-formed layers. Flame-laminated composite bodies are also commonly used. In flame casing, the foam part made of polyurethane is usually guided in a sheet-like manner over open gas flames, whereby the surface melts and becomes sticky. The non-woven fabric web, which may contain soap, is then placed on the surface that has become sticky and connected to the sponge part by pressing and cooling. The sheet or sheet-shaped laminate is then cut to the desired formats.

The nonwoven fabric sheet usually contains abrasives and serves as a scouring medium for cleaning pots and pans and other dishes. For cleaning bathtubs and sanitary facilities, similar scouring sponges are used However, scrubbing power is generally lower. For cleaning Teflonized or other sensitive surfaces there are also scouring pads without additional abrasives.

The handle part of the scouring sponges is used for wiping and vacuuming, but essentially also as a handle for the scouring fleece attached to him.

Scouring pads loosen the encrustations stuck in pans, pots, etc. due to the rough surface of the Scouring fleece, supported by those in the scouring fleece containing abrasive grains in a purely mechanical manner. In the case of stubborn dirt, it is necessary to additionally use previous cleaning agents to facilitate the removal process and, for example, fats and oils, that are on the dishes, to emulsify. In addition to the Seheuersehwamm and Wasehwasser must therefore also Liquid cleaning agents are applied to the item to be cleaned or to the Seheuersehwamm, so that the user still has an additional one in addition to the Seheuersehwamm Detergent needed.

Soheuersehwämme have also become known that contains soap in the scouring part and / or in the handle part. When water gets in, some of the soap is dissolved, which then supports and strengthens the cleaning effect of the scouring fleece under the skin. However, it is felt to be very disadvantageous that in such "saponified" monkey sponges out the soap solution formed by water and soap into the pores of the handle part · Foam penetrates and leads to particularly intensive foam formation in the wrong place. The sponge part is usually only used as a handle in the presence of foamy, usually also greasy soap uncomfortable and useless at this point.

The innovation is now based on the task of developing a "saponified" Scheüerschwarnm that can be handled cleanly, in that the handle part remains free of lather when exposed to water.

The object is achieved by the protection claims described scouring pad.

Due to the innovation according to the design, the interface between soap and sponge is largely or even completely sealed, but not the interface between soap and scouring fleece. A plastic film that is cut to match the inserted soap, cleaning paste or the like and this against the handle is preferred Seals · A suitably cut plastic container is also useful, which also has the task of “keeping the handle part free of soap” In many cases, a waterproof coating of the cavity between the handle part and the abrasion part is sufficient. The waterproof coating is based on Kimst resin. In any case, the interface is sealed so that the foam formation occurs only at the desired point, namely in the scouring layer made of nonwoven fabric.

It is. Very beneficial that after the end of the cleaning work, when the still wet scouring pad is put aside no water can penetrate from the sponge part into the soap, so that further dissolution of the soap is prevented Cleaning work is limited and the service life of the soap mass is significantly extended.

Chafing part and handle part are by flame caking or Gluing connected to each other. The sealing film can be attached particularly easily that one or several foil baths, the width of which is narrower than that d & r manufacture scouring sponges, while the gluing process is inserted between the sponge web and the scouring nonwoven web, so that a gluing - be it through

Adhesive or by flame lamination - in the area of the film does not come about between the nonwoven fabric and the sponge. Figure 1 shows such a shaped body. Figure 2 shows the same shaped body with inserted soap. The scrubbing part 1 is glued to the sponge ax 2. The soap 4 is through the film 3 separated from the sponge part.

In some cases it is desirable to use one for the soap larger cave volume is provided. The cavity can be milled locally or as a continuous channel in the sponge part, melted down or burned in. When melting down or burning in, there is a certain compression of the hollow * room wall, which is then additionally covered with foil or a waterproof plastic paint-coated. Figure 3 shows a Schurammteil with a groove, which through the foil

FIG. 4. In the foam part 2, a channel is incorporated, which is separated from the abrasion part 1 by the film 3.

A particularly advantageous embodiment of the inventive scouring sponge is that the optionally Coarse scouring fleece containing abrasives is integrated into the handle part by foaming over the entire surface. At least on the contact side, the pores of the scouring fleece are penetrated with foam, which creates a Sealing results. Here, too, it is possible to insert the foil provided for sealing the soap.

According to an expedient embodiment of the scouring pad At least one channel-shaped cavity is provided for receiving the soap, cleaning paste or the like. The gutter

is at least one side accessible from the outside, so that soap can be refilled when the first filling is used up. Different types of soap can also be used or can be worked without soap.

According to a further embodiment of the innovation according to the t

Scouring sponge is milled in the handle part, a cavity or a groove, melted or burnt, is suitable for the I recording of an additional sealing element, for example a 'plastic container. Such an embodiment is shown in FIG. The container must be designed in such a way that it is open to the nonwoven side so that water can enter there and the soap can gradually dissolve.

It is essential that the cavity provided for receiving the soap is always open to the abrasive fleece side. He can also be designed in any way and dimensioned to suit the respective purpose.

It is also essential that the handle part is completely or largely sealed against the soap solution, it is usually sufficient if only the part of the interface between the nonwoven fabric and the sponge that is in the area of the soap is sealed.
