Description

The present invention describes a multiphase detergent tablet, its use and method using such a tablet.

Toilet cleaning agents are available to consumers in a variety of different forms. In addition to liquid cleaning agents, toilet cleaning pieces or toilet stones are particularly popular. These agents, which are used to clean, disinfect and scent toilets, are used, for example, below the edge of the toilet's pool (so-called rim blocks) or in the toilet's water or cistern (so-called in-tank blocks or cistern blocks).

Manufacturers and consumers place a number of different requirements on these toilet cleaning agents, with manufacturability, storability and transportability being of particular importance.
In addition to product aesthetics, one of the most important product criteria for consumers is the product lifespan, which in the case of toilet cleaning pieces is determined by their dissolving and rinsing behavior. In order to avoid frequent re-dosing of the toilet cleaning stick in the toilet or its cistern, these cleaning pieces should be rinsed evenly and for a long time and not be washed away by the incoming water, but rather remain reliably in the toilet or cistern.

Aesthetically pleasing spherical toilet cleaning pieces with good rinsing behavior for use below the basin edge of a toilet are described in the German patent application DE 10 2009 003 088 A1 disclosed.

In the European patent application EP 055 100 A1 describes multi-phase toilet cleaning blocks of various geometrical shapes for use in the toilet cistern.

If toilet cleaning blocks are placed in the cistern of the toilet, the consumer has the difficulty of determining the end of the service life of the cleaning block without having to repeatedly open the cover of the cistern. A conceivable solution to this technical problem is the use of colored toilet cleaning blocks, the lack of dye in the toilet flushing liquor giving the consumer an indication of the end of the life of the cleaning block.

Against this technical background, the object was to provide a detergent tablet for use in a toilet cistern which, in addition to an aesthetically pleasing shape, is characterized by ease of manufacture and good storage and transportability. In addition, the molded body should be superior to conventional means with regard to its flushing behavior and should remain reliably in the toilet cistern even with different flow conditions in different cisterns and ensure the uniform release of active substances into the aqueous liquor of the toilet cistern. Finally, the detergent tablet should have an indicator which shows the consumer the imminent end of his life.

This object was achieved by a multiphase detergent tablet with a specific geometry.

A first subject matter of the claim is a cleaning agent molding, comprising a bearing surface and a dome surface adjoining the bearing surface, the cleaning agent molding having a core phase and a shell phase at least partially surrounding this core and the distance between the core phase and the bearing surface being less than the distance between the core phase and the coupling surface.

The shaped bodies are preferably dimensionally stable. "Dimensionally stable", as used herein, refers to the property of the molded body to maintain its three-dimensional shape under the conditions customary for storage and transport, i.e. in the temperature ranges customary for storage and transport and under the action of the forces customary for storage and transport, neither to disintegrate nor to be irreversible Enter into deformations.

The detergent molding comprises a support surface and a dome surface. The contact surface and the coupling surface are adjacent to one another and are separated from one another by an edge. A surface on which the molded body can rest is referred to as a support surface. For this purpose, the support surface comprises at least three support points. The diameter of the support surface corresponds to the maximum distance between two associated support points.

A distinction must be made between the contact surface of the detergent tablet. The contact surface corresponds to the surface with which a cleaning agent tablet, which rests with its contact surface on a flat surface, is in contact with this surface. In the case of a flat contact surface, the contact surface is identical to this.

If the detergent tablet is introduced into the cistern of a toilet, it will change its spatial orientation due to the usual flow conditions in the toilet cistern until its contact surface rests on the floor of the cistern. Due to the improved adhesion of the molded body to the cistern floor associated with this spatial orientation, the movement of the molded cleaning agent body in the water reservoir is minimized or completely prevented. In this way, a uniform rinsing behavior is achieved and at the same time prevents the detergent tablet from being rinsed out of the cistern.

In a preferred embodiment, the bearing surface of the detergent tablet is flat. By designing a planar or level bearing surface, the bearing and adhesive behavior of the molded body on the cistern floor can generally be improved. If the contact surface is planar, assuming a planar cistern floor, the contact surface is identical to the contact surface of the detergent tablet with the cistern floor if the detergent tablet is oriented accordingly in the water reservoir. Preferred flat support surfaces are circular.

A particularly preferred shaped cleaning agent body comprises a planar, circular bearing surface and a dome surface adjoining this bearing surface.

The support surface described above can be modified in different ways. In a first modification, the support surface of the detergent tablet can have impressions. These impressions can be, for example, geometric patterns, pictorial forms, warning notices, letters, names, numbers or brand names. For better identification, the embossments and the supporting surface surrounding them can have different colors. For example, the embossments can be colored.
For a given contact surface, the embossments reduce the contact surface between the detergent tablet and the cistern floor. In other words, the contact surface is larger than the contact surface of the detergent tablet with the cistern floor. The embossing can extend to the edge of the support surface. In such an embodiment, the planar course of the edge of the support surface is interrupted. Such molded bodies tend, when in use, to wash away from the side of the support surface in the area of the embossments reaching to the edge of the support surface and thus to an irregular and unpredictable rinsing behavior. In a preferred embodiment, the embossments are therefore completely surrounded by the bearing surface, in other words, they do not extend to the edge of the bearing surface.

• - der Reinigungsmittelformkörper eine Kernphase und eine diesen Kern wenigstens anteilsweise umschließende Mantelphase aufweist und der Abstand der Kernphase zur Auflagefläche geringer ist als der Abstand der Kernphase zur Kuppelfläche;
• - die Auflagefläche Einprägungen aufweist, welche nicht bis an den Rand der Auflagefläche reichen.

Preferred detergent tablets, comprising a flat bearing surface and a coupling surface adjoining the bearing surface, wherein

• the detergent tablet has a core phase and a shell phase which at least partially encloses this core and the distance between the core phase and the support surface is less than the distance between the core phase and the coupling surface;
• - The support surface has embossments which do not extend to the edge of the support surface.

In an alternative embodiment, the support surface has planar and concave sections. In this embodiment, the entire bearing surface is not curved in a concave manner. Rather, partial areas or sections of the support surface are concavely curved, while other sections or partial areas are flat. An example of such a surface structure are two, three, four or more concave recesses arranged randomly or regularly in the area of the support surface.
If the concave sections extend to the edge of the support surface, the planar course of the edge of the support surface is interrupted. The edge between the support surface and the dome surface runs in a wave shape in such molded bodies. Detergent tablets in which the edge between the support surface and the dome surface is undulating are preferred for aesthetic reasons.
As already described in the case of the detergent tablets with embossments, however, these tablets also tend to wash away from the side of the support surface in the area of the concave depressions reaching to the edge of the support surface and thus to an irregular and unpredictable rinsing behavior. In a preferred embodiment, the concave sections are therefore completely surrounded by the support surface, in other words, do not extend to the edge of the support surface.

With regard to the adhesion of the molding to the cistern floor, the rinsing behavior and the whereabouts of the detergent molding in the cistern, detergent tablets in which the edge between the support surface and the coupling surface is flat have proven advantageous.

In a continuation of the embodiment described above, the bearing surface is designed to be completely concave. In other words, the contact surface between the detergent tablet and the bottom is formed solely by the edge region of the support surface which surrounds the concave bulge of the support surface.

In the case of a support surface oriented spatially downwards, the dome surface adjoins the support surface above. The dome surface can be designed in different ways.

With regard to the adhesion of the molded body to the cistern floor, the rinsing behavior and the whereabouts of the detergent tablet in the cistern, detergent tablets have proven to be particularly advantageous in which the detergent tablets have a ratio of the maximum diameter of the contact surface to the maximum diameter of a cross-sectional area of the dome surface 1 parallel to the contact surface : 20 to 4: 5, preferably 1:15 to 2: 3 and in particular 1:10 to 1: 2.

In a first embodiment, the dome surface is convex polyhedral. In addition to the contact surface, such a cleaning agent tablet has a large number of further boundary surfaces. In the case of a convex polyhedral dome surface, the bearing surface is larger than each of the further boundary surfaces in the area of the dome surface. The ratio of the area of the supporting surface to the area of the largest further boundary surface of the convex polyhedral dome is preferably at least 2: 1, preferably 2: 1 to 80: 1 and in particular 4: 1 to 60: 1.

A further subject of the application is a cleaning agent tablet comprising a support surface and a convex polyhedral dome surface adjoining the support surface, the detergent tablet having a core phase and a shell phase that at least partially encloses this core and the distance between the core phase and the support surface is less than the distance between the core phase and the coupling surface and the area ratio of the supporting area to the area of the largest further boundary area of the convex polyhedral dome is at least 2: 1, preferably 2: 1 to 80: 1 and in particular 4: 1 to 60: 1.

For the spatial orientation of the shaped body in the cistern and the rinsing behavior of the shaped body, it has proven to be advantageous to at least partially round off the dome surface.

For the spatial orientation of the shaped body in the cistern and the predictability of the flushing behavior of the shaped body, it has also proven to be advantageous if the shaped body has an axis of symmetry orthogonal to the support surface.

Particularly preferred are detergent tablets which have a circular or ellipsoidal cross-sectional area, preferably a circular cross-sectional area, parallel to the support surface. In the same way, detergent tablets are preferred which have a cross section in the form of an arc of a circle or an arc of an ellipse, preferably in the form of an arc, orthogonally to the support surface.

Rounded, for example spherical or ellipsoidal dome surfaces have advantages over the convex polyhedral dome surfaces described above in terms of their flushing behavior, in particular with regard to the uniform and long-lasting flushing behavior and its predictability in toilet cisterns of different designs and with different flow ratios.
The detergent tablets with a convex polyhedral dome surface are in turn superior to the hexahedral detergent tablets with regard to their rinsing behavior and its predictability.

• - der Reinigungsmittelformkörper eine Kernphase und eine diesen Kern wenigstens anteilsweise umschließende Mantelphase aufweist und der Abstand der Kernphase zur Auflagefläche geringer ist als der Abstand der Kernphase zur Kuppelfläche;
• - der Formkörper parallel zur Auflagefläche eine kreisförmige Querschnittsfläche aufweist;
• - der Formkörper orthogonal zur Auflagefläche einen Querschnitt in Form eines Kreisbogens aufweist.

In summary, such detergent tablets are particularly preferred which comprise a planar, circular support surface and a dome surface adjoining the support surface, wherein

• - the detergent tablet has a core phase and a shell phase at least partially surrounding this core and the distance between the core phase and the support surface is less than the distance between the core phase and the coupling surface;
• the shaped body has a circular cross-sectional area parallel to the support surface;
• - The shaped body has a cross section in the form of an arc of a circle orthogonal to the support surface.

In other words, detergent tablets are particularly preferred which are in the form of a spherical segment, the detergent tablet having a core phase and a shell phase at least partially surrounding this core and the distance between the core phase and the support surface being less than the distance between the core phase and the coupling surface.

As already described in connection with the support surface, the detergent tablet can also have impressions in the area of the dome surface. These impressions can also be geometric patterns, pictorial shapes, warning notices, letters, names, numbers or brand names. For better identification, the embossments and the supporting surface surrounding them can have different colors. For example, the embossments can be colored.

The detergent tablet comprises a core phase and a jacket phase which at least partially surrounds this core. In one embodiment, the core phase is completely enclosed by the shell phase. This embodiment is less preferred due to the increased expense in production.

Both in terms of manufacturability and in terms of the desired exhaustion indicator, it is preferred if the ratio of the distance between the core phase and the support surface to the distance between the core phase and the coupling surface is less than 0.8, preferably less than 0.2 and in particular less than 0 , Is 1.

Detergent tablets in which the core phase comes into contact with the surface of the detergent tablet in the area of the contact surface are very particularly preferred. In other words, in these detergent tablets, the core phase forms part of the outer surface of the tablet. The proportion of the core phase in the total outer surface of the molded body is preferably 1 to 20%, more preferably 2 to 15% and in particular 4 to 12%.

For the producibility and the exhaustion indication it has proven to be advantageous to design the core phase to be cylindrical.

The volume ratio of shell phase to core phase is preferably 40: 1 to 1: 1, more preferably 30: 1 to 2: 1 and in particular 25: 1 to 4: 1.

The detergent tablets described above develop their advantageous technical properties in particular when they are introduced into the cistern of a toilet. The use of the detergent tablets disclosed in this description for cleaning or scenting the water in a toilet cistern is therefore a further subject of this application.

In particular, those uses are preferred in which the molded body remains in the toilet cistern for at least 40, preferably at least 80 and in particular at least 200 flushing cycles.

The specific technical features disclosed above and below in connection with the detergent tablet also apply mutatis mutandis to their use. To avoid repetition, reference is made to the explanations given there.

As stated above, the shaped bodies are preferably suitable for remaining in the toilet cistern for at least 40, preferably at least 80 and in particular at least 200 flushing cycles.

Against the background of the desired service life for the detergent tablets, they preferably have a weight of 10 to 160 g, preferably 15 to 120 g and in particular 20 to 90 g.

The density of the detergent tablets is preferably 1.2 to 2.0 g / cm ³ , particularly preferably 1.4 to 1.9 g / cm ³ and in particular 1.5 to 1.8 g / cm ³ . These density ranges have proven to be particularly advantageous in combination with the specific three-dimensional shape of the molded bodies with regard to the orientation and remaining in the cistern. For the same reasons, the contact surface of the detergent tablets preferably has a maximum diameter of 3 to 20 mm, preferably 4 to 18 mm and in particular 5 to 15 mm.

The volume of the detergent tablets is preferably in the range from 8 to 100 ml, preferably from 12 to 80 ml and in particular from 15 to 60 ml.

• - das Verhältnis des maximalen Durchmessers der Auflagefläche zu dem maximalen Durchmesser einer zu der Auflagefläche parallelen Querschnittsfläche der Kuppelfläche 1:20 bis 4:5 beträgt;
• - der Reinigungsmittelformkörper ein Gewicht von 20 bis 90 g aufweist und
• - die Dichte des Reinigungsmittelformkörpers 1,5 bis 1,8 g/cm³ beträgt.

Preferred detergent tablets have a bearing surface and a coupling surface adjoining the bearing surface, wherein

• the ratio of the maximum diameter of the bearing surface to the maximum diameter of a cross-sectional area of the coupling surface parallel to the bearing surface is 1:20 to 4: 5;
• - The detergent tablet has a weight of 20 to 90 g and
• - The density of the detergent tablet is 1.5 to 1.8 g / cm ³ .

The detergent tablets can be single-phase or multiphase. Single-phase moldings are preferred because they are easier to manufacture.

1. a) 20 bis 90 Gew.-% wasserdispergierbares Trägermaterial
2. b) 10 bis 80 Gew.-% Aktivstoffe

umfasst. Als Aktivstoffe werden dabei vorzugsweise Tenside, Duftstoffe und Farbstoffe eingesetzt. Ganz besonders bevorzugt ist eine Wirkstoffkombination, umfassend Tensid, Duftstoff und Farbstoff.In addition to a water-dispersible carrier material, the detergent tablets preferably contain one or more active substances as essential components. It is particularly preferred if the detergent tablet

1. a) 20 to 90% by weight of water-dispersible carrier material
2. b) 10 to 80% by weight of active ingredients

includes. Surfactants, fragrances and dyes are preferably used as active substances. An active ingredient combination comprising surfactant, fragrance and dye is very particularly preferred.

The detergent tablets comprise at least two phases, the shell phase and the core phase. Spatial sections of the shaped body which differ from one another with regard to their composition are referred to as phases.
The desired exhaustion indicator is based on the different compositions of the shell phase and core phase. The exhaustion of the product can be indicated, for example, by a change in the color or smell of the water flowing out of the toilet cistern that is perceptible to the consumer when the flush is actuated. The display of exhaustion by means of a color change has proven to be particularly effective and perceptible.

In a preferred embodiment, the shell phase and the core phase therefore differ with regard to the type or amount of the dye contained in them, preferably with regard to the type of dye contained in them. For example, it is possible to add dyes with different hues to the shell phase and the core phase. However, it is very particularly preferred if the shell phase does not contain any dye, while the core phase contains at least one dye, since in this embodiment the color change can be perceived particularly reliably.

The characteristics of some preferred detergent tablets can be found in the following tables (data for the carrier material and the active ingredients in% by weight based on the total weight of the agent, unless otherwise stated). The detergent tablets characterized in more detail in these tables comprise a core phase and a shell phase which partially encloses this core, the core phase reaching the surface of the cleaning agent tablet in the area of the contact surface and the core phase and the shell phase differing in terms of the type of dye they contain.
The ratio of the maximum diameter of the bearing surface to the maximum diameter of a cross-sectional area of the dome surface parallel to the bearing surface is preferably 1:20 to 4: 5, preferably 1:15 to 2: 3 and in particular 1:10 to 1: 2.

1. a) introducing a detergent shaped body according to one of points 1 to 19 into the water reservoir of a toilet cistern;
2. b) actuation of the flush with at least partial replacement of the water reserve in the toilet cistern

is another subject of this application. The toilet cistern used in this method preferably has a flat floor. In the context of this process, a single detergent tablet or a plurality of detergent tablets can be introduced into the water reservoir of the toilet cistern at the same time. However, it is preferred to introduce a single detergent tablet into the water reservoir, which remains there for at least 40, preferably at least 80 and in particular at least 200 wash cycles.
