Definitions

• the invention relates to a device for delivering at least one water-soluble active substance to a cleaning brush, in particular for toilet cleaning, with a receiving element in which the active substance is arranged and which can be detachably fastened to the brush handle of the cleaning brush by means of a holding element.
• DE 100 26 522 A1 discloses a device for the metered delivery of cleaning agent to a cleaning brush, in particular for toilet cleaning, with a product container for the cleaning agent, the product container being designed for releasable attachment to the brush handle of the cleaning brush, and at least one push-in side wall area and an underside Has outlet opening, which opens when pressure is exerted on the depressible side wall area.
• a product container for the cleaning agent the product container being designed for releasable attachment to the brush handle of the cleaning brush, and at least one push-in side wall area and an underside Has outlet opening, which opens when pressure is exerted on the depressible side wall area.
• the product container is provided with a holding element, which is preferably designed as a clamping element with a plurality of spreading spring tabs, which makes it possible to adapt the device to different brush handle diameters, ie to use it universally for different cleaning brushes.
• a holding element which is preferably designed as a clamping element with a plurality of spreading spring tabs, which makes it possible to adapt the device to different brush handle diameters, ie to use it universally for different cleaning brushes.
• the device has proven itself, it presupposes that the user actually exerts pressure on the product container so that the liquid active substance escapes and reaches the area of the bristle head. Furthermore, this known device is only suitable for liquid active substances.
• a generic device is known from WO 02/09567 A1. This device has a receiving element, preferably designed as a ring, which is clamped onto the brush handle of a cleaning brush. The active substance is arranged on this receiving element and is attached to the receiving element in a suitable manner.
• This device is basically suitable for various active substances, in particular also for solid, gel-like and / or granulate-like.
• the handling of this device is unsatisfactory since the user has to attach the active substance to the receiving element, which means that the user has to touch the active substance himself, which is unacceptable.
• the object of the invention is to improve a generic device so that its handling is simplified and product dispensing is metered as precisely as possible.
• the receiving element for the active substance is designed as a closed product container which has a plurality of first openings on the top side and a plurality of second openings on the underside.
• the device thus has a closed product container in which the active substance is arranged.
• the user himself does not come into contact with the active substance, since the active substance is not accessible from the outside, but is inside the product container.
• the device can thus be easily clamped to the brush handle of a cleaning brush in an easy-to-use manner.
• the Product container with first and second openings on the top and bottom, it is possible to set a largely precisely metered amount of product dispensing in coordination with the active substance selected in each case, since both the number and the size of the openings can be selected so that during a rinsing process in the toilet bowl a predeterminable amount of water enters the product container, dissolves part of the active substance and leaves the product container with the dissolved active substance.
• the device can also be operated in such a way that the cleaning brush is pressed into the sump of the toilet bowl, water then entering the product container through the second lower openings and dissolving an amount of active substance.
• the composition, the shape and the production of the active substance also influence the precise dosage and the speed of product delivery.
• a higher pressure when pressing these pieces can lead to a lower solubility, which results in a slower product release.
• smaller pieces of cleaning agent are used or if the agent is used in the form of granules, the surface area is much larger, which also increases the rinsing speed.
• Detergent blocks with a uniform rinsing rate are already known from European patent EP 0 268 967 B1.
• the combinations of active substances described in this document in the quantitative ratios mentioned there can also be used for the purposes of the present invention.
• the detergent pieces mentioned in EP 0 167 085 B1 can also be used for the purposes of this invention.
• the active substance suitable for use in a product container according to the invention can contain one or more of the ingredients mentioned below:
• Anionic surfactants including the monoalkyl sulfate sodium salts, have been found to be particularly suitable for active substances in the form of bars. These are the monosodium salts of sulfuric acid monoesters of long-chain, preferably unbranched, alcohols of natural or synthetic origin. The descendants of fatty alcohols are particularly preferred, and among these in turn coconut alkyl sulfate and lauryl sulfate. The use of ethoxylated fatty alcohol sulfates is also possible.
• Other suitable anionic surfactants include, in particular, alkylbenzenesulfonates.
• Gel-like active substances preferably contain nonionic surfactants.
• nonionic surfactants ethylene oxide (EO) with long-chain aliphatic alcohols with 12-18 C atoms are particularly suitable.
• EO ethylene oxide
• alkyl polyglycosides can also be used as constituents of active substances according to the invention.
• acids can also be used as further components of the active substance.
• suitable acids are citric acid, malic acid, succinic acid, gluconic acid or amidosulfonic acid. These acids can also be used in the form of their salts, in particular in the form of their alkali salts.
• Water-soluble dyes may also be present. Dyes which do not diffuse prematurely from the active substance are preferably used. In addition to a cleaning effect, the active substances should preferably also have a fragrance effect. Therefore, particularly preferred compositions also contain perfume. It should be noted in particular that, in the case of solid cleaning products, the decrease in surface area during the period of use of these products can reduce the impression of fragrance. This undesirable phenomenon can be avoided by using a detergent piece with a core that contains a higher concentration of fragrance, analogously to the subject of European patent EP 0 791 047 B1. This higher concentration largely compensates for the reduced fragrance release due to the smaller surface, so that the consumer does not perceive a diminishing fragrance impression.
• Gel-shaped thickeners contain a thickener to adjust the desired viscosity.
• the polysaccharides known from the prior art as gel formers are preferably used, for example xanthan gum.
• the type and amount of the thickener used can also influence the rinsability of the agent.
• the product container has an upper wall surface on the upper side in which the first openings are provided, the ratio of the total area of the first openings to the total area of the upper surface being between 20 and 50%, preferably between 25 and 40% ,
• the product container preferably has a lower wall surface on the underside, in which the second openings are provided, the ratio of the total area of the second openings to the total area of the lower surface being between 20 and 80%, preferably between 45 and 55%.
• the product container consists of an upper part and a lower part.
• the product container can preferably be produced by the plastic injection molding process.
• the product container can be in two parts, but it is preferably in one part, i.e.
• the upper and lower parts are then preferably connected to one another via film hinges and locking elements.
• the active substance is inserted or filled in with the upper part open, then the upper part is closed and the filled and closed product container can then be inserted into a sales packaging.
• the product container has a lateral slot-shaped recess for attachment to the brush handle and for receiving the holding element.
• the mounting element itself can either be attached to the product container in a suitable manner or can be formed in one piece with it.
• the lateral recess preferably merges into an enlarged cylindrical recess on the underside. This makes it possible that the device can be arranged directly above the bristles in almost all cleaning brush types, since the upper cylindrical part of the bristle head, which is usually expanded relative to the brush handle, can then be accommodated in the recess.
• the active substance can in principle be of any design, for example it can be solid be stick-like, granular or gel-like.
• anionic surfactants were used in the form of the sodium salts in the compositions mentioned.
• the following abbreviations are used in the examples:
• cylindrical granules (diameter 5 mm, height 4 - 8 mm),
• Viscosity 20D (Brookf., LV-DV II +, spindle 25, 1 RPM) - 140,000-180,000 MPa.s.

• the product container 1 has a lower wall surface 4 on the underside, in which a plurality of second openings 5 are provided.
• the first openings 3 are crescent-shaped and the second openings 5 are elongated. These geometric shapes have proven to be particularly favorable.
• the product container 1 preferably consists of an upper part 6 which has the upper wall surface 2 and a lower part 7 which has the lower wall surface 4, each of which is formed in the shape of a half shell and is connected to one another in one piece. For this purpose, they are hinged to one another via film hinges 8 and have corresponding latching elements 9, 10.
• the upper part 6 and the lower part 7 are pivoted together and locked together with the aid of the latching elements 9, 10, so that a product container 1 which is closed in the position of use is available, as shown in FIGS. 1 and 3.
• the product container 1 has a lateral slot-shaped recess 11 such that the product container 1 is C-shaped or U-shaped when viewed from above.
• This recess 11 serves to receive a mounting element, generally designated 12, which can be inserted into the recess 11 or can also be formed in one piece with the product container 1.
• this holding element 12 has an upper clamping ring 12a and a lower clamping ring 12b, which are slotted towards the recess 11 and can be expanded and enable lateral clamping to a brush handle 13 of a cleaning brush. From this cleaning brush a bristle head 14 with cleaning bristles 15 is also shown, the bristle head 14 is approximately cylindrical and has a larger diameter than the brush handle 13.
• the lateral recess 11 of the product container 1 goes into an underside enlarged cylindrical recess 16 over.
