Description

 Cleaning body for a bristle-free cleaning device, cleaning device and method for producing a cleaning body

The present disclosure relates to a cleaning body for a bristle-free cleaning device, in particular a brushless toilet cleaning device, wherein the cleaning body has a body and a cleaning portion, wherein the cleaning portion extends from the trunk, and wherein the cleaning body with a plurality of raised cleaning elements is provided, which are arranged at least partially on a surface of the cleaning body. The invention further relates to a method for producing a cleaning body.

A similar cleaning device is known from DE 10 2012 106 164 B3. It is a cleaning device with a handle with a handle portion, with an at least partially flexible cleaning body, on a the The handle body is at least partially provided with a plurality of raised cleaning elements, wherein at least the stem or the cleaning body is provided with an antimicrobial substance, wherein the cleaning body is formed of an elastic plastic, and wherein the antimicrobial substance is added to the plastic or applied as part of a coating on the plastic.

[0003] The terms "bristle-free" cleaning devices, bristle-free toilet cleaning devices or "bristle-free toilet brushes" may be understood to mean cleaning devices which, unlike traditional cleaning brushes, are designed without bristles, ie without hair-like or rod-shaped cleaning elements. It has been shown that even with bristle-free cleaning devices, which are provided with nubs, a good cleaning effect can be achieved. This can be accompanied by the significant advantage that the surfaces of bristle-free cleaning devices are less susceptible to attachment of dirt, debris, paper or the like. This can have a particularly advantageous effect on the external appearance of bristle-free cleaning equipment, which is not significantly impaired even after prolonged use.

DE 20 2014 001 997 U1 relates to a scented toilet brush in general, but without going into any way on ways to make such a toilet brush or the more detailed structural design of such a toilet brush. DE 20 2014 001 997 U1 does not give the skilled person any help for reworking such a toilet brush.

From WO 87/0041 1 A1, a cleaning device for toilet bowl is known, which has a disposable cleaning part, which is designed as a sleeve part, wherein the sleeve part is impregnated with an indicator that the ingress of water and thus the Indicates the end of a temporary waterproofness. The desired temporary waterproofness can be achieved by impregnating with water-soluble substances. In this case, the solution process of the impregnating agent can be indicated by a color change. [0006] DE 10 2010 034 453 A1 discloses a process for producing a masterbatch containing a TPE composite, wherein the masterbatch comprises a thermoplastic elastomer and at least one perfume contained therein, wherein the perfume during an extrusion process or before an extrusion process is mixed with the thermoplastic elastomer, wherein a processing temperature during the extrusion process is below the softening point of the raw material used. In this way, a masterbatch can be produced with a fragrance, which can then be mixed in a further process step with another thermoplastic elastomer composite, extruded and processed in a molding process. This does not occur at such a reduced processing temperature.

From DE 37 21 916 A1 a process for the perfuming of articles made of plastics is known, wherein a perfume adsorbed on a powdery porous carrier in an amount of 1 to 70 percent by weight and optionally pressed in the presence of a binder to a granulate wherein the resulting immobilized powdery, optionally granulated perfume is mixed with the plastic and the homogeneous mixture is processed by pressing, injection injection molding, extruding or blowing. This is basically not done at reduced processing temperatures.

The above-mentioned DE 10 2012 106 164 B3 also proposes to provide a cleaning body of the cleaning device with an antimicrobial substance in order to minimize the growth or multiplication ability of microorganisms to affect as clearly as possible. This, too, can have an advantageous effect on the condition of the cleaning device, in particular the optics of the cleaning device are not negatively adversely affected even with prolonged use.

However, it has been shown that further optimization possibilities are given in bristle-free toilet brushes. On the one hand, this can affect the cleaning effect. Furthermore, this may relate to the external appearance, in particular to the perception by a user. Against this background, the present invention seeks to provide a cleaning body for a bristle-free cleaning device, a bristle-free cleaning device, which is provided with such a cleaning body, and possibly a method for producing a cleaning body for a bristle cleaning device, which has an improved cleaning effect and moreover have a perceivable as a valued external appearance. Preferably, the cleaning body can be produced by means of a method which enables the production of cleaning bodies with little effort and in particular enables the provision of tailor-made customer-specific functions.

This object is related to the cleaning body, achieved by a cleaning body for a bristle-free cleaning device, in particular a brushless toilet cleaning device, wherein the cleaning body has the following:

 a hull, in particular a reinforced hull, which has a connecting section for coupling the cleaning body to a handle,

 a cleaning section extending from the hull and having a thickness extension and an areal extent, wherein a maximum thickness extent and a maximum areal extent have a ratio of less than 1: 5, preferably less than 1:10, more preferably less than 1 : 15 is, and

 a plurality of raised cleaning elements, which are arranged at least in sections on a surface of the cleaning body, in particular on the cleaning section,

 wherein the cleaning body is formed of an elastic base material, in particular of a silicone material or a rubber material, wherein the cleaning body forming the base material is provided with an antimicrobial substance, and wherein the cleaning body forming base material is provided with at least one perfume additive.

The object of the invention is completely solved to this. Namely, a cleaning body is provided according to the invention, which in functional terms sufficiently separated from each other has sections, in particular the hull and the cleaning section. The hull may, for example, be reinforced by a corresponding material thickening. Accordingly, the hull can ensure a stable connection of the cleaning body to a handle or a similar handle. In contrast, the cleaning section is configured substantially flat, such as tongue-like or beak-like. In this way, the cleaning section is sufficiently flexible to adapt to a surface to be cleaned. This can help to ensure that even hard-to-reach sections (such as a urinal or a toilet bowl) can be cleaned safely and with little effort.

The cleaning body thus has a stable "backbone", namely the hull. In contrast, the cleaning section is significantly more flexible, so that in particular concave surfaces, depressions and the like can be cleaned.

Furthermore, the antimicrobial substance can help to reduce pollution or microbial infestation of the cleaning device or even completely or at least almost completely avoided. The cleaning objects to be cleaned with the cleaning device, in particular sinks, regularly have a high water throughput, so that hardly any superficial contamination or deposits occur there over time with sufficiently frequent cleaning.

It is customary to record the cleaning devices used in the cleaning of objects, in particular toilet cleaning devices, between individual cleaning operations in suitable receptacles or holders and store. The images may be about cup-like, bag-like, napfformige or similar shaped body. Usually, the cleaning devices are stored with the cleaning body first in the recordings. Since, for example, the cleaning of a sink with the cleaning device basically takes place wet, ie with the aid of water, the cleaning device regularly has a residual moisture at least in the region of the cleaning body after cleaning. This can have the consequence that in particular the cleaning body is still introduced moist into the receptacle to store the cleaning device can. Over time, therefore, a considerable amount of liquid can accumulate in the receptacle for the cleaning device, which can be microbially contaminated. It must generally be expected that in particular toilet bowls can never be completely and completely cleaned from a microbial perspective.

Consequently, in the storage or support of the cleaning device serving recording a highly microbially contaminated environment arise. Over time, this can lead to deposits being formed on the cleaning device, in particular on its cleaning body, which can cause an unaesthetic impression. From a medical or hygienic point of view, a long-lasting microbial growth in the intake for the cleaning device or the cleaning device itself is disadvantageous and can increase a potential risk of infection. This is particularly true considering the fact that the cleaning devices are generally stored many times longer in the recording, as they are actually used for cleaning.

On the other hand, the antimicrobially active substance can contribute to the fact that microbial deposits on the cleaning device can be prevented in their growth or even killed. Thus, the cleaning device can be in use for a long time and remain in the recording, without looking "old" or even "dirty" from an aesthetic point of view. At the same time, a potential risk of infection, which in principle can be associated with microbial burden, can be significantly reduced. Microbially contaminated cleaning devices may have unpleasant odors especially when moistened. Such additional loads can be reduced or completely avoided by means of the antimicrobial substance.

The term "antimicrobially active substance" may in principle be understood to mean substances which impair the reproductive capacity of microorganisms. This may include a reduction in the ability to reproduce. However, an antimicrobially active substance can also be designed to completely or almost completely prevent the multiplication of microorganisms. It is It is also conceivable that the antimicrobial substance directly kills microorganisms. Antimicrobially active substances can be directed, for example, against bacteria, against fungi, against yeasts or against other microorganisms.

In the cleaning device may be a hand-held device for cleaning toilets, which basically works without bristles. In this respect, the cleaning device can also be referred to as bristle-free cleaning device. Nevertheless, the plurality of cleaning elements formed on the surface of the cleaning body can provide a sufficiently grippy contour which also permits the removal of stuck dirt.

The bristle-free design of the cleaning device can lead to a reduction of the manufacturing effort. Furthermore, the bristle-free design can generally lead to a reduced surface, at least in the case of the cleaning body itself, so that less (potentially preloaded) liquid can adhere to the cleaning body overall, for example after a cleaning process, compared with conventional toilet brushes. Already by this measure, a microbial contamination can be reduced.

The perfume additive may comprise at least one perfume but also a perfume composition. In particular, the fragrance additive may be molded together with the base material. In other words, the perfume additive may be present in the material forming the cleaning body at least substantially homogeneously. For this purpose, the base material, the perfume additive and possibly

further additives or aggregates are processed together. It is also advantageous if at least the base material, the antimicrobially active substance and the at least one perfume additive are processed together. This may in particular include a common shaping, such as an injection molding process in a mixed or mixed state.

Usually, the production of the cleaning body comprises a vulcanization of the elastic base material. Preferably, the at least one fragrance Substance additive, more preferably also the antimicrobial active substance, the base material mixed before vulcanization.

The processing and vulcanization of the elastic base material usually requires an increased processing temperature. This can be, for example, in the range between 150 ° C (Celsius) and 220 ° C. Preferably, the processing temperature of the elastic base material is in a range between 160 ° C and 180 ° C. If in this disclosure of a "processing temperature" is mentioned, this may be understood as a temporarily occurring maximum temperature or vulcanization temperature, which is exposed to the elastic base material during the manufacturing process.

Fragrances are generally chemical substances that are olfactory perceptible, so "smelling" are. With the sense of smell a fragrance can be perceived. Fragrances can be generally natural and / or synthetic. In this context, a fragrance may also generally be referred to as a fragrance.

The at least one perfume may be present in the liquid state, in the pulverulent state and / or in the granular state. Fragrances may include individual fragrance compounds, e.g. As the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons. Fragrance compounds of the ester type are e.g. Benzylacetate, phenoxyethylisobutyrate, p-tert-butylcyclohexylacetate, linalylacetate, dimethylbenzylcarbinylacetate, phenylethylacetate, linalylbenzoate, benzylformate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate. The ethers include, for example, benzyl ethyl ether, to the aldehydes z. For example, the linear alkanals having 8 to 18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cycloalanaldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones z. The alcohols include anethole, citronellol, eugenol, geraniol, linalol, phenylethyl alcohol and terpineol, the hydrocarbons include mainly the terpenes and balsams. Other fragrances of synthetic and natural kind are conceivable. Preferably, mixtures of different fragrances are used, which together produce an attractive fragrance. Further information on perfume additives in plastic materials, in particular in elastic materials can be found for example in the published patent applications WO 2007/144056 A1 and DE 10 201 1018 965 A1.

It is advantageous if the at least one perfume additive (which can also be generally referred to as at least one perfume additive) is selected and / or treated in such a way that there is no impairment, at least none, as a result of the processing of the base material added or provided with the perfume excessive impairment, the scent effect (olfactory effect) occurs. In other words, it is preferred if the at least one perfume additive is selected taking into account the expected processing temperature of the base material.

Alternatively, it may also be advantageous to select and / or adjust the base material so that a required processing temperature is adapted to a temperature that does not affect the effect of at least one perfume additive, but at least not excessively impaired.

In this context, it is conceivable to adapt process parameters for the processing and processing of the base material. By way of example, a temperature occurring during the vulcanization of the base material can be reduced, if a longer vulcanization time is accepted as compensation.

Another measure may be to provide the elastic base material with additives or additives that lower the processing temperature. By way of example, these may be so-called crosslinkers or crosslinking materials. This can be used in particular for elastic base materials based on a rubber material. Typical wetting agents or crosslinking materials may be sulfur additives and / or peroxides. In particular, peroxides are preferred as crosslinkers for rubber materials, in particular for natural rubber materials. In this way, the processing temperature of the base material can be significantly reduced. Accordingly, excessive deterioration of the effect of the perfume additive by the processing can be avoided. Chemical crosslinking agents such. For example, sulfur or organic peroxides may link polymer chains to a three-dimensional network under appropriate conditions. The crosslinking reaction changes many material properties of the polymer. The crosslinked polymers often show properties that are superior to the corresponding properties of the sulfur vulcanized.

The perfume additive can give the cleaning body a fragrant scent. This can be particularly beneficial in the sanitary environment. It is advantageous if the at least one perfume additive is released by the cleaning body over a certain period of time. The desired period may include, for example, several months to several years.

It may also be advantageous if the cleaning body is designed such that occur in the application occurring loads for increased release of fragrance. This can be due to various effects. By way of example, it is conceivable that the cleaning body heats up at least in sections, for example due to friction. In the heated state, the cleaning body can deliver a larger amount of perfumes. Similar designs are known for various types of erasers. In the application of erasers heat is usually generated due to the friction occurring in the material of the eraser itself. This can activate the delivery of fragrances. Similar principles of action can be transferred to cleaning bodies for bristle-free cleaning devices, even if the technical areas are far apart. Alternatively, it would be conceivable to cause the increased release of perfume additives by wetting the cleaning body with water.

In this context, reference is made by way of example to DE 20 2013 005 066 U1. The German utility model patent discloses the use of fragrances in toilet cleaners. However, the document does not address the issue of how to obtain and / or manufacture such a cleaning device in order to actually deliver fragrances in the desired manner. It is particularly preferred if the cleaning elements are arranged both on the cleaning section and on the hull. It is essential that the cleaning elements are arranged at least in sections on the cleaning section. The cleaning section can essentially be designed as a flat piece and, compared to the hull, have increased elasticity, which is brought about in particular by the geometric design of the cleaning section.

It is particularly preferred if the cleaning body is designed as a one-piece integrally manufactured cleaning body. In this way, no assembly of various components is required to complete the cleaning body. Furthermore, it is preferred if the cleaning body is made close to the demoulding or almost demoulding. This means in other words that preferably no further processing of the (once urgeformten) cleaning body is required. However, this does not exclude that Entgradvorgänge or the removal of cast skins may be required. It is particularly preferred if the cleaning body does not have to undergo any further relevant machining operations after removal from a corresponding mold. This may in particular include that no surface coating, no painting and no similar further manufacturing steps are required.

According to a further embodiment, an indicator substance is added to the base material forming the cleaning body, in particular an indicator substance which causes a change in color of the cleaning body over time. It can be particularly advantageous if the indicator substance chosen such that a clearly perceptible color change of the cleaning body occurs approximately when the olfactory effect of the at least one fragrance additive noticeably decreases or threatens to subside.

It is understood that at most a rough adjustment can be made with regard to the expected periods. Nevertheless, it is preferred if the indicator substance is adapted to the at least one perfume additive in such a way that a user is also visually indicated that a declining scenting is to be expected. By way of example, the indicator substance may be chosen such that over time a fading of a coloring of the cleaning body is perceptible. Accordingly, the indicator substance may also be adapted to a dye or a colorant, which may also be added to the base material.

In general, the base material may be a silicone material, a rubber material or similar elastomers or elastomeric materials. In the course of processing the base material, various additives, impact substances and the like may be added. A corresponding mixture, which can be added to the base material, can be referred to as a masterbatch. Usually, the masterbatch is a suitably prepared highly concentrated material or a suitably prepared material mixture which can be added to the base material in order to be processed together with the base material (in particular by prototyping) in order to form the cleaning body.

Rubbers are usually amorphous high molecular weight substances, although the plastics are similar in structure, but differ from them at the molecular level. Rubbers can also be generally referred to as crosslinkable plastics. The crosslinking of rubbery materials can generally be referred to as vulcanization. In principle, natural rubbers and synthetic rubbers are known.

Furthermore, thermoplastic elastomers are known. These are substances whose properties are quite similar to those of rubber materials. However, thermoplastic elastomers may have the property of dissolving their crosslinks at high temperatures. If cooled, re-crosslinking may occur.

Rubber materials may include, for example, natural rubber (NR), butadiene rubber (BR), butyl katuschuk (HR), chloroprene rubber (CR), ethylene-propylene terpolymer (EPDM), fluororubber (CFM), isoprene rubber (IR), Nitrile rubber (NDR), silicone katuschuk (Q), styrene-butadiene rubber (SBR) and the like.

For the processing of rubber materials, additives are of immanent importance. These may be required to enable the production of the molding compounds to be processed and to produce the desired properties in the finished product. Rubber materials can usually be processed by means of extrusion, pressing and / or injection molding.

Silicone-based rubber materials may also be referred to as silicone rubber or as silicone elastomers. Silicone rubber can be understood as meaning crosslinkable materials which contain poly (organo) siloxanes and can accordingly be converted into the rubber-elastic state. Silicone rubbers can be provided with fillers and with additives or with additives. Aggregates may in particular comprise dyes and at least one perfume additive. Furthermore, so-called liquid silicone (liquid silicone rubber) is known, which is particularly suitable for processing by injection molding due to a relatively low viscosity.

For use as a base material suitable silicone materials are sold for example under the brand Xiameter by the company Dow Corning. An exemplary thermoplastic elastomer is sold, for example, under the name UNISOFT TPE ST-70A-NT-1 -24 by United Soft Plastics, Inc. USA.

A suitable example of an antibacterial additive is sold under the name 0/122793 (antibacterial additive D6000 2.5%) by AW Kunststoff Farbkonzentrate GmbH. According to one embodiment, the antimicrobially active substance may be, for example, a silver-containing substance which is marketed, for example, under the name "Ultra-Fresh CA-16". Such or similar substances can be added to the base material, or applied as part of a coating on the base material. Fragrances or fragrance compounds can be obtained from, for example, the companies Kraiburg TPE GmbH & Co. KG and comparable suppliers. With regard to the introduction of fragrances into plastic components, reference is again made to WO 2007/144056 A1. In addition, reference is made again to DE 10 201 1018 965 A1, which deals with fragrance depots which are formed by a matrix of natural rubber or silicone rubber, in the interior of which a fragrance or a fragrance mixture is enclosed.

Suitable dyes can be obtained, for example, under the name BASF Color Solutions from BASF.

Additives or additives that are used in the manufacture of components made of crosslinkable materials, can fulfill different purposes. By way of example, the use of so-called crosslinkers can be considered. These are, in particular, sulfur or sulfur-based crosslinks, which are sold for example under the trade name Crystex. Furthermore, so-called vulcanization accelerators can be used, which are marketed for example under the name Vulkazit in various embodiments.

In particular, the use of so-called peroxide crosslinkers is preferred. These are distributed for example under the names Lucidol, Varox, Dicup and Vulcup. The choice of a suitable peroxide crosslinker can help to lower the processing temperature to a tolerable level.

Furthermore, so-called anti-aging agents are known which are partially discoloring effect. These may be, for example, additives sold under the name Vulkanox. By way of example, it is conceivable to use Vulkanox 4010 NA or similar products marketed by Lanxess AG, Germany. In particular, when the base material is a natural rubber material, it is conceivable to use sulfur or sulfur-based substances as an indicator substance. These can cause the cleaning body to fade over time. Suppliers of additives and similar additives for plastics processing can be found, for example, in the article concentrated action, additives and Farbbatches, the journal Plastverarbeiter, May 2008 issue.

The fragrances can basically be mixed in powder form or in the liquid state of aggregation with a base material. Furthermore, fragrances are known which are provided in the form of granules, for example in the form of pearls. It is conceivable, for example, to produce the masterbatch upstream of the actual processing of the base material. The masterbatch can in particular have dyes and fragrances in highly concentrated form. By way of example, an initial masterbatch can be used which can be obtained, for example, as a color additive. It is conceivable that such a masterbatch is in granular form. Now, the granules can be mixed with the fragrances to be added. By way of example, the fragrances can be applied to the granules in liquid form. It may be followed by a mixing process. Alternatively or additionally, a drying process can follow. The drying process can, especially when the fragrances are applied in liquid form, drag on for several hours, for about 4 to 10 hours. The final masterbatch provided in this way can be used for the production of the cleaning body.

According to a further embodiment, the hull, viewed in a longitudinal direction, which coincides with a longitudinal extent of the cleaning body, a tapered mandrel or elliptical cross section. In other words, the hull may be designed approximately conical or conical. However, the cone forming the fuselage preferably has oval cross-sections. It can thus be a "flattened" cone. According to this embodiment, the hull can taper in the direction of a tip of the cleaning body. A base of the fuselage may be provided with the attachment portion for coupling the cleaning body to the stem.

According to a further embodiment, the fuselage, viewed in a frontal view, has a substantially triangular shape, wherein a base side in the region of the base surface is substantially transverse to a longitudinal extent of the cleaning surface. training body is formed, wherein two lateral sides extend from the base side and meet in a tip of the hull, which is arranged on a longitudinal axis of the cleaning body. In particular, the lateral sides of the fuselage need not be designed as ideal straight lines. It is conceivable that the lateral sides, viewed in the frontal view, are curved, in particular comprising a convex or concave configuration. Generally speaking, the hull can be designed as a cone with a flattened (oval) cross-section.

In an alternative embodiment, the fuselage, viewed in a longitudinal direction which coincides with a longitudinal extent of the cleaning body, has a cross-sectional profile which, starting from a base surface with a substantially oval cross-section, merges into a transitional region into a cross-section whose main axis is longer is a major axis of the oval cross section and its minor axis is shorter than a minor axis of the oval cross section. In other words, according to this embodiment, the hull has a squat base or base surface and becomes slimmer in the direction of a tip of the cleaning body, whereby a transverse dimension can increase. The substantially oval cross-section of the base surface may be designed approximately as an ellipse.

In other words, this design may include that the hull, viewed in a longitudinal direction, which coincides with a longitudinal extent of the cleaning body, has a tube-shaped, in particular a tube-section-like shape. By way of example, the shape of the trunk may correspond approximately to an outer shape of an end portion of a toothpaste tube.

In a preferred embodiment, the surface extension of the cleaning section defines a silhouette of the cleaning body in the front view, which is designed triangular, diamond-shaped or heart-shaped. The surface extension may in particular comprise a longitudinal extent and a transverse extent. A thickness extension or thickness of the cleaning section extends in particular perpendicular to the surface extension. According to a further embodiment, the raised cleaning elements are formed as knobs and designed in particular as lenticular or spherical elevations. In this way, the cleaning elements on the one hand improve the cleaning effect and facilitate a mechanical release of adhesions or dirt. On the other hand, the raised cleaning elements (mechanically) can be stably integrated into a shape of the cleaning body.

According to an alternative embodiment, the raised cleaning elements are formed as raised cleaning webs or cleaning edges, which preferably have a main extension, which is oriented substantially transversely to the longitudinal extent. In other words, the cleaning elements may be substantially bead-shaped and have a cross-section which extends in the transverse direction along the surface of the cleaning body, in particular along the surface of the cleaning section. In this way, the effect of the cleaning body, in particular the mechanical cleaning effect can be optimized.

It is further preferred if in particular the cleaning section comprises an at least partially circumferential cleaning edge, which opens into a cleaning tip. Thus, the cleaning tip can be used for about scraping off soiling. A peripheral region provided with the cleaning tip can connect a front side and a rear side of the cleaning body.

According to a further embodiment of the connection portion of the hull allows a positive reception of the cleaning body on a stem, wherein the connecting portion has at least one undercut for securing the position and at least one driving contour to prevent rotation. In other words, the at least one driving contour can prevent a relative rotation between the cleaning body and a handle on which the cleaning body is received. The at least one undercut can ensure a secure connection of the stem to the cleaning body in the longitudinal direction and in particular prevent unwanted loosening of the stem from the cleaning body. Preferably, the at least one undercut can be removed from the mold by forced removal. In this regard, in particular the elastic properties of the base material can be used. The design of the connection section can also simplify changing the cleaning body. Because of the inherent elasticity of the base material, namely, the cleaning body can be solved by the application of a defined release force from the stem. By way of example, a new cleaning body could then be placed on the stem again.

According to a further embodiment, the cleaning body is integrally made of an elastomeric base material, in particular of an elastic polymer, preferably of a Silkonwerkstoff or a rubber material.

Rubber materials can be generally referred to as rubber-based materials. Rubber-based materials may include synthetic rubber, natural rubber, oil rubber and the like or mixtures thereof.

According to a further embodiment, the antimicrobial active substance contains silver-containing constituents. This embodiment can be further developed in that the antimicrobially active substance is incorporated into a carrier matrix which contains zeolites.

Silver can be highly antimicrobial effective. In particular, silver ions can be incorporated or incorporated in the zeolites. In this way, the zeolite can serve as a depot and release the antimicrobial active substance over a longer period. Thus, the antimicrobial effect of the cleaning device can be maintained over a long period of time. Silver can occur in the form of nanoparticles.

According to a further embodiment, the perfume additive is provided as a master batch, in particular in combination with a dye. According to a further embodiment, the base material is provided with impact substances to lower a processing temperature, in particular a crosslinking temperature of the base material.

In this way, the shaping of the cleaning body can be carried out at particularly low temperatures, this can have an advantageous effect on the effectiveness of at least one perfume additive.

Preferably, a cleaning body according to any one of the preceding aspects is provided in a cleaning device, in particular in a toilet cleaning device. The cleaning device can also be referred to as a toilet brush. In view of the bristle-free design, the cleaning device may be referred to as a brushless toilet brush.

wherein the processing takes place at a processing temperature which is adapted in such a way to a thermal resistance of the at least one perfume additive, that the perfume additive is fragrantly effective after cooling and demolding. Preferably, the processing takes place at a reduced processing temperature.

In other words, the at least one perfume additive and / or the processing temperature can be selected and adapted to one another such that after production the dispensing of perfumes from the cleaning body is made possible. This implies that the effectiveness of the at least one perfume additive is not impaired or at least not unduly impaired by the manufacturing process.

Various fragrances or fragrance additives are known which can withstand such processing temperatures for at least a short time without losing any of their effect.

The method can be developed by the following step: providing at least one crosslinking agent, in particular providing at least one crosslinking agent based on peroxide, the step of the joint processing jointly processing, in particular a common injection molding, the base material, the antimicrobial substance, of the at least one perfume additive and the crosslinking agent. The peroxides may in particular be organic peroxides.

The method may be further developed by the following step: Providing an indicator substance, in particular an indicator substance, which causes a color change of the cleaning body over time, wherein the step of the joint processing comprises a common processing, in particular a common injection molding of the base material, the antimicrobial substance, the at least one fragrance additive of the indicator substance and , if present, of the crosslinking agent.

According to a further embodiment of the method, the step of providing a base material comprises providing a base material of an elastomeric base material, in particular of an elastic polymer, preferably of a silicone material or a rubber material.

In general, it is also conceivable to use a base material of a thermoplastic elastomer (TPE). It is also possible to produce cleaning bodies with the desired properties on the basis of thermoplastic elastomers. According to another embodiment, the step of co-processing comprises vulcanization of the base material. A required processing temperature, which may also be referred to as vulcanization temperature, may be lowered by using suitable additives and / or additives which promote cross-linking. Furthermore, the vulcanization can be carried out at a reduced temperature, provided that a corresponding longer vulcanization time is accepted.

Furthermore, it may be advantageous to provide a mold comprising a plurality of nests for producing a plurality of cleaning bodies. In this way, a high output can be ensured even with correspondingly extended cycle times.

The method may be further developed by the following step:

 - Forced removal of a connection section, comprising generating at least one undercut in the cleaning body for the positive reception of a stem.

By way of example, the method for producing the cleaning body when using a base material of natural rubber or based on natural rubber can be designed as follows:

First, a starting product - which may be referred to as raw rubber - are crushed. On this basis, a molding compound can be produced. In particular, the rubber can be mixed with a plasticizer. It is understood that semi-finished starting materials for use as a base material can also be purchased externally.

The rubber-based molding compound may be provided with various additives. Aggregates may include, for example, carbon blacks and fillers, plasticizers, processing aids, vulcanizing agents, anti-aging agents, colorants and / or blowing agents. It is understood that the abovementioned Impact substances can be added. In particular, at least one perfume additive can be added to the molding composition. Furthermore, at least one indicator substance can be added to the molding compound.

The mixture of the raw rubber, optionally plasticizers, and additives can be mixed in mixers or kneaders and homogenized. In particular, kneading can reduce the viscosity of the natural rubber, so that the mixing with the aggregates is simplified.

In a desired manner, therefore, a starting material, which may also be referred to as a plasticine, be added to a desired color and with a desired perfume. Suitable combinations of colors and fragrances may include, for example, the color red and strawberry-like fragrances, the color blue and fresh scents / sea scents, the color green and spring scents and similar combinations. Accordingly, it is conceivable to produce a multiplicity of variants (in particular concerning the color and the perfume additive) on the basis of a uniform starting product or intermediate product.

By way of example, the perfume in the liquid state can be added to a plasticine already mixed with the paint. It may be followed by another mixing or kneading to mix the starting material, the color and the scent sufficiently homogeneous.

Alternatively, the generation of a masterbatch is conceivable that at least the perfume additive and the dye - each in concentrated form - and can be added to the starting material.

In the injection molding of elastomeric materials is generally the higher viscosity of the molding material (compared to thermoplastic materials) to pay attention. Furthermore, usually the tool (ie the mold) is heated to accelerate a desired vulcanization. Accordingly, processing temperatures can be found which are approximately in the range of 180 ° C to 220 ° C. However, in order not to permanently damage the fragrance additives, it may be advisable to process the elastomeric material at a lower temperature, for example in the range between 140 ° C and 180 ° C. Preferably, the processing takes place in a temperature window between 140 ° C and 160 ° C, more preferably between 140 ° C and 150 ° C. Ideally, the processing takes place at temperatures below 160 ° C, preferably below 150 ° C, more preferably below 140 ° C. It is understood that the temperatures mentioned can represent maximum values that are only achieved temporarily and / or locally.

In principle, it is to be expected that, due to the processing of the starting materials associated with a temperature increase, there will be a change in the fragrance note of the at least one fragrance additive. By appropriate experiments, which may include a variation of the fragrances and / or a variation of the process parameters for the processing of the molding composition, however, "recipes" can be found that are process reliable and repeatable nacharbeitbar and lead to stable results, especially with respect to desired scent.

It will be appreciated that the cleaning body may be formed in accordance with at least some of the method aspects described herein. The disclosure may in principle also be a method for producing a cleaning body. The manufacturing method may thus also be developed in accordance with at least some of the device aspects described herein.

It is understood that the features of the invention to be explained below and those to be explained below can be used not only in the respectively specified combination but also in other combinations or in isolation, without departing from the scope of the present invention.

FIG. 14 shows a side view of the cleaning device according to FIG. 12; FIG. and 15 is a highly simplified schematic block diagram for illustrating an embodiment of a method of manufacturing a cleaning body for a bristle-free cleaning apparatus.

Fig. 1 shows a partial perspective view of a cleaning device, which is generally designated 10. Fig. 2 shows a corresponding frontal view. Fig. 3 shows a corresponding side view.

The cleaning device 10 may also be generally referred to as a toilet cleaning device. Usually, toilet cleaners are referred to as toilet brushes. Since the cleaning devices 10 described in the context of this disclosure are bristle-free cleaning devices, they can also be referred to as bristle-free toilet cleaning devices or as bristle-free toilet brushes.

The cleaning device 10 has a cleaning body 12 and a handle 14. In the figures 1, 2 and 3, the stem 14 is shown only in sections. The stem 14 can usually be a rod-shaped component which has a grip portion and a coupling portion, wherein the coupling portion is designed to be coupled to the cleaning body 12. There are many types of designs for the stem 14 conceivable. Thus, the handle 14 may be configured approximately substantially rectilinear, that is to say extend approximately substantially in a longitudinal direction X. However, it would also be conceivable to make the handle 14 at least partially curved. This can bring ergonomic benefits.

In a combination of FIGS. 1, 2 and 3, a coordinate system X, Y and Z results, which describes different main directions of extension of the cleaning device 10 and of the cleaning body 12, respectively. A longitudinal direction is designated by X. A transverse direction is designated Y. A depth direction is designated Z.

Preferably, the cleaning body 12 at least substantially consists of an elastomeric material, in particular of a rubber-based material. This can basically be natural rubbers and synthetic rubbers include. For example, the use of silicon chunks would be conceivable. Likewise, the use of thermoplastic elastomers is conceivable.

According to the embodiment illustrated with reference to FIGS. 1, 2 and 3, the cleaning body 12 may have a body 16, to which a cleaning section 18 may adjoin. The body 16 and the cleaning portion 18 may have a main extension direction coincident with the longitudinal direction X. In particular, the cleaning portion 18 may have a depth extension in the depth direction Z, which is substantially smaller than its extension in the longitudinal direction X and in the transverse direction Y. In other words, the cleaning portion 18 may extend substantially flat in a plane defined by the axes X and Y.

The cleaning body 12 is at least partially provided with raised cleaning elements 20. The raised cleaning elements 20 may be, for example, nubs or knob-like cleaning elements. These may be at least partially designed at least approximately spherical. In general, the raised cleaning elements 20 can be convexly protruding cleaning elements. The cleaning elements 20 may generally be formed at least in sections on a surface of the cleaning body 12. Preferably, the raised cleaning elements 20 are arranged at least in substantial areas of a surface of the cleaning section 18. It can be seen from FIGS. 1, 2 and 3 that the cleaning elements 20 can also be formed on the body 16 at least in sections.

The hull 16 may have, for example, a conical shape. Accordingly, the hull 16 have a tip 22 which coincides approximately with a longitudinal axis X of the cleaning body 12 and the cleaning device 10. The hull 16 may further include a base surface 28 that faces the stem 14. In the base surface 28 may further be formed a connection portion 26, which preferably serves for releasably coupling the cleaning body 12 with the stem 14. With regard to exemplary configurations of the connection section, reference is made to FIGS. 9 and 10. The body 16 may have in its longitudinal extent X in the direction of the tip 22 tapered oval or elliptical cross-sections, see. to illustrate Fig. 5 and Fig. 9.

The hull 16 can be designed sufficiently rigid, for example due to corresponding material thicknesses. Accordingly, the trunk 16 can impart high rigidity and strength to the attachment portion 26. In contrast, the cleaning body 12 is easier to deflect or deform due to its flat, thin design. Thus, the cleaning body 12 can easily conform to a surface to be cleaned. This can in particular simplify the cleaning of recesses or of concave surfaces.

Furthermore, the cleaning body 12 may be provided at least in sections with a circumferential edge region 24. Preferably, the edge region 24 is provided at least at the cleaning section 18. The edge region 24 may preferably taper pointedly (outwards). This can further improve the cleaning effect. In other words, the edge region 24 may extend along a path around the cleaning section 18 and may have an approximately triangular cross-section perpendicular to the path forming the tip of the edge.

Generally, the cleaning portion 18 may be designed approximately beak-shaped or tongue-shaped. It is also conceivable to make the cleaning section 18 heart-shaped or similar. Preferably, the cleaning section 18 has a tip 30, which is formed at the end remote from the handle 14 of the cleaning section 18. The tip 30 may be rounded in a suitable manner.

It can also be seen from FIG. 2 that the fuselage 16, viewed from the front, has a base side 42 and two lateral sides 43. The lateral sides 43 can open into the tip 22. Accordingly, the trunk 16, viewed from the front, may have substantially triangular cross sections oriented perpendicular to the depth extension (Z direction). It is understood that approximately the lateral sides 43 may in principle also be curved, ie the corresponding cross sections of the fuselage 16 need not be formed by ideal triangles. Viewed in section, the lateral side 43 can be made approximately convex or concave.

Various exemplary dimensions of an embodiment of the cleaning body 12 are illustrated with reference to FIGS. 2 and 3. In the longitudinal direction X, the cleaning body 12 may have a longitudinal extension 36, which is about 1 10 mm to 130 mm. The cleaning section 18 can also extend along the longitudinal extent 36. This is the case in particular when both the fuselage 16 and the cleaning section 18 extend from the base surface 28. The cleaning body 12, in particular its cleaning section 18, may have in the transverse direction Y a transverse extension or width which is designated by 40 and which may be approximately 90 mm to 110 mm.

The body 16 of the cleaning body 12 may have in the longitudinal direction X a longitudinal extent 38, which may be about 60 mm to 80 mm. A transverse extent or width of the fuselage 16 in the region of the base surface 28 (not explicitly designated in FIG. 2) may be approximately 50 mm to 70 mm.

A depth extent or thickness in the depth direction Z of the cleaning section 18 (neglecting the raised cleaning elements 20) is indicated at 34 in FIG. The depth or thickness may be about 3 mm to 6 mm. The trunk 16 may have a depth extension (not explicitly highlighted in FIG. The cleaning section 18 may be made substantially flat. The hull 16 may be designed substantially conical.

Fig. 4 illustrates an embodiment of a cleaning device provided with a cleaning body 12a, which is not provided with raised cleaning elements, primarily for illustrative purposes. The surface of the cleaning body 12a, in particular at least essential portions of the surface of the cleaning section 18 may be provided with various raised cleaning elements. According to various embodiments, a surface of the fuselage 16 may be provided at least in sections with raised cleaning elements. It may be advantageous to provide no raised cleaning elements in the edge region 24, in particular in its peripheral edge or tip.

5 shows a rear view (also: view from below) of a cleaning body, which basically can be designed to be similar to the cleaning body 12 according to FIG. 1 and / or the cleaning body 12 a according to FIG. 4. For reasons of illustration, the cleaning body 12 according to FIG. 5 (in any case in the view shown there) has no raised cleaning elements. It is understood that in principle described above, the cleaning body 12 may be at least partially provided with cleaning elements 20.

5, the pointed design of the edge region 24 can be further removed. The fuselage 16 of the cleaning body 12 shown in FIG. 5 has a basic shape or a cross section 32, which is designed in an oval shape.

Different designs of raised cleaning elements 20a, 20b, 20c, 20d, 20e, 20f are illustrated and explained in more detail with reference to FIGS. 6a, 6b, FIGS. 7a, 7b and FIGS. 8a, 8b. The mentioned cleaning elements 20 may be formed at least in sections approximately on the surface of the cleaning body 12a according to FIG. 4. It is understood that a sorted arrangement of the cleaning elements is conceivable. However, it is also understood that a combination or "mixture" of different cleaning elements 20 is conceivable.

Fig. 6a illustrates plan views of two substantially rotationally symmetrical cleaning elements 20a, 20b. FIG. 6b illustrates corresponding cross sections through the cleaning elements 20a, 20b according to the lines VI-VI in FIG. 6a.

[00122] FIG. 7 a illustrates plan views of non-rotationally symmetrical lenticular cleaning elements 20 c, 20 d, which by way of example have an oval basic shape. sen. FIG. 7b illustrates these associated cross sections along the lines VII-VII in FIG. 7a.

Fig. 8a illustrates cleaning elements 20e, 20f, which have a dominant longitudinal extension, so about cleaning webs or cleaning edges can form. FIG. 8b illustrates corresponding cross sections of the cleaning elements 20e, 20f along the lines VIII-VIII in FIG. 8a.

An advantageous design of a connection section 26 formed on the fuselage 16 will be explained in more detail with reference to FIGS. 9 and 10. In FIGS. 9 and 10, an illustration of the cleaning section 18 is omitted for reasons of illustration. 9 shows a view of the fuselage 16 of a cleaning body 12 (view from below or from a stem). FIG. 10 shows a partial sectional view of the fuselage 16, wherein a section line in FIG. 9 runs along the line X-X.

The connection section 26 may in particular be formed as a connection section 26 which, starting from the base surface 28, is designed as a depression in the fuselage 16. An at least partially sublime design is of course conceivable.

By way of example, the attachment section 26 has at least one central mandrel or a centering tip 44. Further, the connection portion 26 may have an anti-rotation, which may also be referred to as a driving contour 46. In addition, the connection section 26 may have at least one rear snap or undercut 48. A provided for coupling with the cleaning body 12 stem 14 may have a corresponding connection contour, which may correspond substantially to a negative of the connection portion 26 and its recessed contour. Accordingly, the mandrel 44 may center the stem 14. The entrainment contour 46 can cooperate with a corresponding mating contour of the stem 14 to ensure rotation against relative rotation between the stem 14 and the cleaning body 12. Accordingly, it is advantageous if the entrainment contour 46 is designed non-rotationally symmetrically (about the longitudinal axis X). The at least one undercut 48 can be engaged behind and / or underrun by a corresponding collar or projection of the stem 14. In this way, a loosening or falling off of the stem 14 from the cleaning body 12 can be prevented. Preferably, the attachment portion 26 may be positively deformable. This is conceivable in particular because of the high elasticity of the base material. In this way, the production cost, in particular the cost of providing a mold or mold, significantly reduced. By way of example, FIG. 10 shows two undercuts 48.

FIG. 11 shows a greatly simplified partial section through a cleaning object 50, in particular through a toilet bowl. The cleaning object 50 has a wall 54 and an inner edge 56. The inner edge 56 may define about an opening. An arrow designated 52 describes a common access direction, via which an interior region of the cleaning object 50 is accessible to a cleaning device 10. However, in order to be able to reach a region which extends between the inner edge 56 and the wall 54, it is necessary to bend or bend at least one cleaning body 12, in particular its cleaning section 18, at least in sections, cf. a dashed arrow labeled 58 in FIG. However, since the substantially flat designed cleaning section 18 on the one hand is deformable, but on the other hand due to the elasticity can always return to its original position, the cleaning body 12 and a provided with this cleaning device 10, in particular for cleaning hard to reach places, ie about Cleaning a "dead space" behind the inner edge 56.

An alternative embodiment of a cleaning device 10 is illustrated with reference to FIGS. 12, 13 and 14, which has a cleaning body 12b modified with respect to the embodiment according to FIGS. 1, 2 and 3.

The cleaning body 12b is provided in a basically known manner with a fuselage 16 and a cleaning section 18. In the longitudinal direction (X direction), the cleaning body 12 has a first portion 64, which is essentially associated with the body 16, cf. Also, Fig. 13. Further, the cleaning body 12b in the longitudinal direction X on a second portion 66 which substantially the Cleaning section 18 is assigned. In other words, in the longitudinal direction X between the sections 64 and 66, a defined transition between the fuselage 16 and the cleaning section 18 may be formed.

The fuselage 16 may have a substantially oval cross-section which extends from the base surface 28 towards the end 30 of the cleaning body 12. In the region of the base surface 28, the cross section of the fuselage 16 may be oval or elliptical and have a major axis corresponding to the extent in the Y direction and a minor axis corresponding to the extent in the Z direction. In this way, external dimensions of the elliptical cross section can be sufficiently defined. In the course of his

Longitudinal extent (X-extent), the extensions of the main axis and the minor axis can change absolutely and relative to each other. By way of example, the extent of the main axis over the longitudinal extension of the fuselage 16 can increase continuously in the direction of the tip 30. Further, the extent along the minor axis over the longitudinal extent of the trunk 16 in the direction of the tip 30 continuously decrease. In particular, in the region of the transition between the sections 64 and 66, the hull 16 can accordingly pass over in the (essentially flat) cleaning section 18, in particular pass over substantially seamlessly or tangentially.

In other words, the body 16 of the cleaning body 12b may have a shape corresponding approximately to a rear portion of a tube or a toothpaste tube. In particular, the hull 16 can be tube-shaped or tube-shaped. The frontal view according to FIG. 13 can also be seen that a silhouette of the cleaning body 12b, viewed in the frontal direction, can be made polygonal, in particular diamond-shaped or diamond-shaped. However, this does not necessarily mean that opposing sides of the diamond must ideally be parallel to one another.

In general, the silhouette of the cleaning body 12b in the front view can also be understood as a combination of two trapezoidal shape elements which touch each other on the respective longer side of their parallel sides. In fundamentally prescribed manner, the cleaning section 18 can be used in the longitudinal direction. direction (X direction) in one end 30 leak. Furthermore, an edge region 24 or an at least partially circumferential edge may be formed, which preferably opens into a pointed edge. It is understood that the edge of the edge region 24 may not necessarily be designed to be pointed in an ideal manner. Rather, the edge may also have a relatively small transition radius, which is, for example, due to the design of the tool used for the shaping of the cleaning body 12b.

The surface of the cleaning body 12b, in particular the surface of its cleaning section 18 can be provided in the manner described above with raised cleaning elements, in particular with the illustrated with reference to Figures 6a to 8b cleaning elements 20a-20f.

However, it may be preferable to provide the surface of the cleaning body 12b at least in sections with cleaning elements 20e, which extend substantially in the transverse direction (Y direction) approximately perpendicular to the longitudinal direction X. The cleaning elements 20e may be referred to as cleaning blades or as cleaning edges. By way of example, the cleaning body 12b illustrated with reference to FIGS. 12, 13 and 14 has five cleaning elements 20e arranged in the cleaning section 18, in particular arranged parallel to one another. The cleaning elements 20e may be arranged or distributed at a constant distance from one another (in the longitudinal direction X) along the longitudinal extension of the cleaning section 18.

It is understood that cleaning elements having a dominant transverse extent (Y extension), that is to say the cleaning elements 20e and 20f, can in principle also be combined with the designs of the cleaning bodies 12, 12a, which are illustrated with reference to FIGS become. Even with substantially in the transverse direction Y extending cleaning elements 20e, 20f, a good removal rate can be achieved.

FIG. 15 illustrates, by means of a highly simplified schematic block diagram, an exemplary embodiment of a method for producing a Cleaning body, in particular a cleaning body for a bristle cleaning device. Preferably, a cleaning body produced according to the method is used in a bristle-free toilet cleaning device or in a bristle-free toilet brush.

The method may include a step S10 that includes selecting and providing a base material. Preferably, the base material may be a crosslinkable elastomeric material. The base material may in particular be a rubber material or a rubber-based material. Conceivable, for example, natural rubbers, silicone rubbers and similar materials. Likewise, thermoplastic elastomers are conceivable. Usually, the base material is provided with various additives and / or additives or mixed with them. Accordingly, the method may include, for example, a step S12 comprising providing at least one perfume additive. In particular, step S12 may comprise providing a combination of different perfume additives. The perfume additives may be provided and processed in granular form, pasty form, liquid form, or the like.

The method may further comprise a step S14 comprising providing at least one indicator substance. By way of example, the indicator substance may be designed to visually indicate an aging of the cleaning body to be produced. This can be done for example by a discoloration and / or discoloration. Preferably, the indicator substance is at least approximately adapted to the at least one perfume additive in such a way that the indicator substance can indicate when a perfume depot in the cleaning body has been used up. This can be done, for example, by temporal adaptation of the indicator substance to be expected discoloration of an expected decrease in fragrance delivery (for example below a certain threshold).

The method may further comprise a step S16 involving the provision of further adjuncts. Aggregates may also include additives. The aggregates may be, in particular, wetting agents or crosslinking agents, for example in the form of peroxide-based substances. These can in particular increase the tendency of the base material to crosslink. In this way, the with the crosslinking of the base material incoming vulcanization process in a shorter time and / or at a lower vulcanization temperature (in general also: processing temperature) take place. This can bring about the significant advantage that the processing temperature can be lowered in such a way that, during the shaping of the cleaning body, no destruction or substantial impairment of the effect of the at least one perfume additive takes place.

The method may further comprise a step S18 comprising providing at least one dye. Preferably, the at least one dye is adapted to the perfume additive to produce a "consistent" sensory impression in a user.

The steps S12, S14, S16 and S18 may be followed by a step S20, which includes the generation of a concentrate or a masterbatch. In this way, a highly concentrated mixture of different aggregates can be provided which can be mixed with the base material. The mixing or mixing can take place in a subsequent step S22. It is understood that the mixing, mixing or admixing of at least some of the substances provided in steps S12, S14, S16 and / or S18 can be staggered over time. Furthermore, it is conceivable that at least some of the substances provided in steps S12, S14, S16 and / or S18 are added directly to the base material (and not to a masterbatch.

After step S22, a processable intermediate may be provided which is essentially due to the base material and various additives. A further step S24 of the method may comprise the provision of at least one mold for shaping a cleaning body. Preferably, molds having a plurality of nests are provided, so that a plurality of cleaning bodies can be produced per production cycle. The mold can essentially provide at least one cavity that can be filled with the material composition intended for further processing. The at least one mold may also be heatable and / or coolable to enable temperature management during the molding process. It may be followed by a step S26, which refers essentially to the processing of the material composition. Step S26 may include (sub) steps S28 and S30. The (partial) step S28 may include a shaping, that is to say in particular the introduction of a quantity of the material composition into at least one cavity of a mold. The step S26 may further comprise the (part) step S30 involving crosslinking of the crosslinkable material composition. The processing of the (sub-) steps S28 and S30 can take place under a specific temperature regime and / or time regime. Processing of the (partial) steps S28 and S30 can take place at least partially in parallel. Essential parameters for the vulcanization of crosslinkable materials may in particular be a vulcanization temperature and a vulcanization time. It may therefore be advantageous to lower the vulcanization temperature and correspondingly extend the vulcanization time in order to avoid any adverse effects on the at least one perfume additive. If the vulcanization can proceed below a critical (temperature) threshold, it is ensured that the finished cleaning body is olfactory (fragrant) effective.

The processing step S26 may be followed by a step S32, which essentially relates to cooling or cooling of the shaped cleaning body. The step S32 may include an active temperature management. In principle, the step S32 can also include a tempering, ie a defined heat treatment, of the cleaning body.

Finally, a step S34 may follow, which comprises demoulding the generated cleaning body from the mold. In particular, the step S34 may include positively deforming a bonding portion of the cleaning body. In this way, an undercut contour can be exposed, which later allows a secure coupling of the cleaning body with a handle.
