Description

TECHNICAL PART

The present invention relates to brush heads and corresponding toilet brushes according to the preamble of the independent claims.

Toilet brushes typically have a short handle handle and a head extended across the handle. The thicker, transversely to the direction of the stem extended head is equipped with bristles or formations with which attachments in a toilet can be replaced. The DE 20 2005 011 730 U1 proposes the use of bristle brush heads, where molded soft edges to allow cleaning. Here, however, the problem may arise that the edge is flat, whereby the pressure force is evenly distributed and stubborn buildup can not be replaced. Against this background, the present invention is located in the field of toilet brushes and brush heads, where bristles are used with small area, selective edition for cleaning.

DESCRIPTION OF THE PRIOR ART

Generic brush heads comprise a main body with a receptacle for a brush handle and protruding from the base plastic bristles. Generic toilet brushes thus have such a brush head. The brush head has a substantially bell-shaped spatial form, in which the bristles, when the brush is held down vertically, reach down towards a hemispherical to elliptical outer boundary, in order to transition upwards into a cylindrical to slightly upwardly widening spatial form. Thus, the space shape resembles an upside-down brush in an upside-down bell. As a storage holder are often placed close to the toilet or mounted receptacle, which provide a cylindrical mold with hemispherical bottom, in which the brush head can be plugged with a slight clamping voltage. Additional bristle or stem formations as used in the DE 200 18 712 U1 or the DE 202 02 910 U1 be suggested here allow additional cleaning of the toilet edge.

From the DE 1649192 U1 is a generic brush head made of rubber, which has molded rubber bristles. Advantage of the rubber head is a significantly increased durability, since the bristles can not break off or break out of the body. A disadvantage of the usual way of bristles made of white plastic is that even with painstakingly regularly rinsed soiling of the brush head quickly unsightly, yellow Kalkalsatz on the body and the bristles is visible. In addition, established, white plastic bristles tend to fix dirt and debris in the dense bristle bundles.

It was therefore an object of the present invention to overcome the disadvantages of the prior art and to provide a brush head which, in addition to an increased durability, can also provide an optically acceptable appearance for a longer time.

The solution of this object is achieved according to the features of the independent claims. Advantageous embodiments will become apparent from the dependent claims and the following description.

DESCRIPTION OF THE INVENTION AND ADVANTAGEOUS CHARACTERISTICS

According to the brush head of a toilet brush, comprising a main body with a receptacle for a brush handle and with the Base protruding plastic bristles, characterized in that the bristles of TPE-V are formed. The inventors believe that the olefin base of such polymers as a hydrophobic, waxy class of compound can provide improved hydrophobicity over the aqueous and water-soluble soils. This can explain why the low wettability with residues and or adhesions was surprisingly good.

The brush head is preferably characterized in that the bristles, individually projecting, have a conically outwardly tapering spatial form with a blunt tip and that the bristles have a thickness over the entire bristle length in the millimeter range. With tips, which are formed thick and blunt ending by one millimeter, can be selectively effect a high contact pressure, with the persistent adhesions can be removed well. At tip thicknesses beyond 4 millimeters, an effective pressing proved to be hardly feasible: on the one hand, the bristles were too stiff due to the continuous thickness of 4 millimeters and more in the group and, on the other hand, were too large on the ceramic surface to be cleaned.

Preferably, the brush head is characterized in that a continuous, one-piece TPE-V body comprises both base body and bristles.

Preferably, the brush head is characterized in that the brush head has an edge cleaner with individually projecting cleaning bristles. 'Edge cleaner' are formations that allow engagement of the cleaning bristles in the bottom of a toilet rim. Examples of possible formations can be found in the prior art. In the present case, it is preferably proposed to form an edge cleaner in the form of a hook which is open upward in the handle direction in a U-shaped manner laterally on the base body and to provide it with cleaning bristles. Preferably, the cleaning bristles on the above-described bristle room form according to claim 2. Particularly preferably, the edge cleaner thus inserts with its bristles into the essentially bell-shaped spatial form of the brush. A still bell-shaped spatial form allows holding the brush head in the well-known prior art receptacles. Advantageously, the U-shaped upwardly open edge cleaner allows cleaning of the edge with vertically aligned brush. With vertical alignment of the brush / the stem is reliably avoided that the opposite edge of the toilet could obstruct the necessary movement of the stem or cleaning or even impossible.

Preferably, the brush head is characterized in that the edge cleaner is part of the integrally formed TPE-V body. This offers the advantage of increasing the versatility of an existing toilet brush with replaceable brush head, without a new handle or a new bracket would have to be purchased.

According to the brush head is characterized in that the TPE-V is colored gray to dark gray. This offers the advantage that even with extremely hard water with a high lime content, no unsightly gray haze is visible due to the then unavoidable, superficial lime deposits. This advantageous measure thus guarantees a lasting attractive appearance of the brush head even under the most adverse conditions.

According to the invention, the claimed toilet brush on a brush head according to the invention, wherein the brush head has a substantially bell-shaped spatial form. The latter advantageously allows the holding of the toilet brush in established brackets and recordings.

Preferably, the toilet brush is characterized in that it comprises a brush handle made of stainless steel. A stainless steel handle fits almost all facilities in the domestic sanitary area and advantageously ensures a harmonious overall appearance of an interior.
