Definitions
- a handle part and a scouring body having a cleaning part serve for a variety of cleaning purposes, in particular the household for cleaning pots, sinks and the like.
- EP-A-0 141 863 describes a scouring pad with a grip part made of soft polyurethane foam and an associated scouring part made of coarse nonwoven fabric. This scouring pad reaches a limit when it comes to stubborn dirt when it comes to cleanability.
- a scrubbing sponge based on steel wool and a foamed plastic is known from DE GM 85 28 882, the foamed plastic being arranged in the center and having a jacket made of steel wool.
- the disadvantage here is that when the scouring pad is gripped, the user is exposed to the risk of injuries from protruding steel wool threads, which can protrude from the scouring pad through intensive use.
- the object of the invention is to provide a scouring body for removing in particular firmly adhering contaminants, which avoids the disadvantages mentioned above.
- the cleaning part consists of angular, coiled cleaning materials made of metallic material, the handle part is at least partially made of foam and the coiled cleaning material is connected to the foam of the handle part on the back of the cleaning surface and on a lateral section.
- the handle can be used to improve the
- Cleaning performance can be polygonal or star-shaped. This creates edges or peaks over which an increased force can be introduced.
- the grip part preferably consists of a foam having a density of 160 to 300 g / m 3 .
- the handle part can have a holding part made of hard plastic, for example made of polypropylene (PP), polyethylene (PE), polyurethane (PU), polyester (PES) or other synthetic resins.
- the holding part can be designed as a knob or as a handle, so that either direct actuation in the hand or indirect pick-up via the handle.
- the grip part can have a circumferential constriction for partial engagement of the fingers.
- the back of the handle part facing the hand can be bulged out or in.
- the cleaning material one above the other in one to five layers, at least one layer also being arranged laterally around the handle part.
- Strips with a rectangular cross-section with a width of 0.5 to 3 mm can be used as cleaning material, which have at least two active edges when placed on the surface to be cleaned.
- the diameter of the helix can be 3 to 6 mm.
- the fixing of the cleaning material to the foam of the handle part can be done adhesively by melting the surface of the foam or by gluing the cleaning material to the surface of the foam. It is possible to make the connection layer liquid-tight or liquid-permeable.
- the production of a scouring body can be effected in such a way that the cleaning material is connected to the foam by melting, with microwave or induction heating taking place. You can either melt a hot glue or the foam itself. A polyurethane foam is particularly suitable for this.
- Fig. 2 is a coil of the cleaning material
- Fig. 3 shows the principle of the double helix of the cleaning material and Figures 4a to 4d special forms of the outer design of the scouring body.
- the scouring body shown in FIG. 1 has a handle part 1 and a cleaning part 2.
- the cleaning part 2 consists of angular, coiled cleaning materials 3, which lie one above the other in several layers 3.1, 3.2.
- the handle part 1 consists at least partially of foam 4, on which the coiled cleaning material 3 is attached.
- the cleaning material 3 is also arranged on the side of the foam 4, for which purpose the foam 4 has a projecting part 4a with a reduced outer circumference.
- the grip part 1 has a holding part 5, which can consist of hard plastic, for example PP, PE, PU.
- the handle part 1 is provided with a circumferential constriction 6, in which the fingers can engage when using the scouring body.
- the back 7 of the handle part 1 facing the hand has a curvature 7 which extends over the entire width of the handle part. This bulge is directed outwards, but an inward curvature can also be provided.
- a foam with a density of 160 to 300 g / m 3 is possible for the foam 4, on which the cleaning material 3 is adhesively attached to the melted surface.
- the foam 4 for example polyurethane, must be meltable.
- the melting can take place via a microwave or induction heating.
- Fig. 2 the cleaning material 3 consisting of metal or plastic is shown in an enlarged view. Shown is a helix 8 of a cleaning material 3 made of a strip with a rectangular cross-section 9.
- the cross-section 9 has four edges, of which two edges 10, 11 are effective towards the outside.
- the diameter D of the helix is 3 to 6 mm
- the width B of the strip is 0.5 to 3 mm.
- a double-spiral cleaning material according to FIG. 3 can also be used, as a result of which the multilayer single-spiral cleaning material is achieved with the same effect.
- the scouring body can be made round or oval, on the other hand as a polygon with inward (Fig. 4b) or outward (Fig. 4c and 4d) edges, the edges themselves being rounded. This creates hexagons, stars or triangles, for example.
