Description
Die vorliegende Erfindung betrifft Wasch- oder Reinigungsmittelformkörper aus verdichteter Wasch- bzw. Reinigungsmittelzusammensetzung, wobei der Formkörper auf seiner Oberseite eine Erhebung aufweist, die eine exponierte planare Fläche umfasst. Die Erhebung ist vorzugsweise reliefartig und dient markierenden, kennzeichnenden oder ausschmückenden Zwecken. Zur Steigerung des kennzeichnenden, markierenden bzw. ausschmückenden Effekts kann die planare Oberfläche der Erhebung eingefärbt sein. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung solcher Wasch- oder Reinigungsmittelformkörper.The present invention relates to detergent tablets of compacted detergent composition, wherein the tablet has on its top a projection comprising an exposed planar surface. The elevation is preferably relief-like and serves marking, marking or decorating purposes. To increase the characterizing, marking or decorating effect, the planar surface of the survey can be colored. The invention further relates to a process for the preparation of such washing or cleaning agent tablets.
Wasch- oder Reinigungsmittelzusammensetzungen werden in Form von flüssigen, pulverförmigen bzw. granularen oder tablettenförmigen Zusammensetzungen im Handel angeboten. Sie werden für verschiedene Anwendungen, einschließlich Wäschewaschen, Maschinengeschirrwaschen, Toilettenhygiene und Baden verwendet. Im Falle der tablettenförmigen Zusammensetzungen, auch Tabs genannt, werden die Wasch- oder Reinigungsmittelformkörper aus verdichteter Wasch- bzw. Reinigungsmittelzusammensetzung hergestellt. Diese Wasch- oder Reinigungsmittelformkörper weisen im Vergleich zu den flüssigen oder pulverförmigen Zusammensetzungen eine Reihe von Vorteilen auf, wie einfache Dosierbarkeit, Handhabungssicherheit, hohe Verdichtung und dadurch einen verringerten Verpackungs-, Transport- und Lageraufwand. Auch aus ästhetischen Gründen können solche Formkörper von Vorteil sein.Detergent compositions are commercially available in the form of liquid, powder or granular or tablet compositions. They are used for various applications including laundry, machine dishwashing, toilet hygiene and bathing. In the case of tablet-like compositions, also called tabs, the detergent tablets are produced from compacted detergent composition. These detergent tablets have a number of advantages over the liquid or powder compositions, such as ease of metering, handling safety, high compaction, and thereby reduced packaging, shipping and storage costs. Also, for aesthetic reasons, such moldings may be advantageous.
Um dem Verbraucher ein typisches und unverwechselbares Produkt zur Verfügung zu stellen, werden die Formkörper vorzugsweise eingefärbt, wobei bei Formkörpern aus mehreren Phasen bzw. Schichten diese Schichten häufig unterschiedlich eingefärbt werden. Eine weitere Möglichkeit, die Formkörper mit einem Herkunftshinweis des Herstellers zu versehen, besteht darin, den Formkörpern eine bestimmte Form zu geben. Jedoch ist es zum Beispiel ungeeignet, solche Wasch- oder Reinigungstabs aus verdichteten Teilchen zu etikettieren, da das Etikett beim Waschen abgehen wird und den Filter der Maschine verstopfen könnte.In order to provide the consumer with a typical and unmistakable product, the moldings are preferably colored, with moldings of a plurality of phases or layers, these layers often being dyed differently. Another way to provide the moldings with an indication of origin of the manufacturer, is to give the moldings a specific shape. However, for example, it is inappropriate to label such detergent or cleaning sticks of compacted particles, as the label will go off during washing and clog the filter of the machine.
Eine weitere Möglichkeit wurde daher darin gefunden, eine der Flächen des Formkörpers mit Buchstaben oder Schriftzügen zu versehen, wie zum Beispiel mit der Produktbezeichnung, dem Firmennamen oder Firmenlogo. Aus dem Stand der Technik ist bekannt, zum Beispiel aus der
Da Wasch- bzw. Reinigungsmittelformkörper aufgrund ihrer Herstellungsweise aus relativ großen, groben Teilchen bzw. Granulat, welches nur bei relativ niedrigen Drücken verdichtet wird, besteht, weisen solche Formkörper in der Regel sehr rauhe, porenförmige Oberflächen auf. Anders als bei zum Beispiel dicht gepressten Arzneimitteltabletten, welche eine glatte Oberfläche aufweisen, eignet sich das Tintenstrahldruckverfahren bei den oft sehr rauhen, offenporigen Oberflächen von Wasch- oder Reinigungsmittelformkörpern nicht so gut.Since detergent tablets, due to their method of preparation, consist of relatively large, coarse particles or granules which are compacted only at relatively low pressures, such tablets usually have very rough, porous surfaces. Unlike densely compressed drug tablets, for example, which have a smooth surface, the inkjet printing process is not very suitable for the often very rough, open-pored surfaces of detergent tablets.
Aus dem Stand der Technik ist weiterhin bekannt, Buchstaben oder Schriftzüge unter Verwendung von Stempeln aufzubringen. So wird in der

Möglichkeit zu finden, um Wasch- oder Reinigungsmittelformkörper auf mindestens einer ihrer Oberflächen mit Buchstaben, Produktbezeichnungen, einem Logo oder sonstigen dekorativen Ausschmückungen zu kennzeichnen, um dem Verbraucher, insbesondere auch sehschwachen Verbrauchern, ein typisches und unverwechselbares Produkt zur Verfügung zu stellen, das leicht über seine Struktur erkennbar ist.Possibility to find detergent tablets on at least one of their surfaces with letters, product names, a logo or other decorative embellishments in order to provide the consumer, in particular low-sighted consumers, a typical and distinctive product that easily over its structure is recognizable.
Die gestellte Aufgabe wird durch einen Wasch- oder Reinigungsmittelformkörper aus verdichteter Wasch- bzw. Reinigungsmittelzusammensetzung, enthaltend Gerüststoffe sowie einen oder mehrere weitere Inhaltsstoffe von Wasch- bzw. Reinigungsmitteln, gelöst, wobei der Formkörper auf seiner Oberseite eine Erhebung aufweist, wobei die Erhebung eine exponierte planare Fläche umfasst und nicht allseitig an den Rand des Formkörpers reicht.The object is achieved by a washing or cleaning agent molded body of compacted detergent composition containing builders and one or more other ingredients of detergents or cleaners, wherein the molded body has a survey on its upper side, wherein the survey an exposed planar surface and does not reach all sides of the edge of the molding.
In einer bevorzugten Ausführungsform der Erfindung lässt dabei die exponierte planare Fläche in ihrer formmäßigen Ausgestaltung eine Kennzeichnung erkennen, die bevorzugt auch leicht ertastet werden kann.In a preferred embodiment of the invention, the exposed planar surface, in its form-fitting design, identifies a marking which can preferably also be easily felt.
Als "Oberseite" des Wasch- oder Reinigungsmittelformkörpers wird diejenige Seite verstanden, von der aus sich die Erhebung abhebt. Die Formkörpergrundfläche, die z.B. durch die Oberseite definiert wird, kann im Rahmen der vorliegenden Erfindung die unterschiedlichsten geometrischen Formen annehmen, vom Dreieck über das Rechteck und dessen Spezialfall, das Quadrat bis hin zu 5-, 6- oder 8-eckigen Formen. Kreis- oder ellipsoide Formen sind ebenfalls bevorzugte Formkörpergrundflächen. Auch andere Flächenformen, wie Sterne oder Tierformen, sind problemlos als Formkörpergrundfläche realisierbar. Bevorzugte Wasch- und Reinigungsmittelformkörper sind dadurch gekennzeichnet, dass die Formkörpergrundfläche im Wesentlichen rechteckig ist und vorzugsweise abgerundete Ecken aufweist. Der Formkörper selbst ist ausgehend von der zugrunde liegenden Formkörpergrundfläche folglich vorzugsweise quaderförmig, wobei jedoch problemlos andere Formkörperformen, wie etwa Würfel, Kugel, keilartige Formen, eiförmige Formen etc. denkbar sind.As "top" of the detergent or cleaning product molding that side is understood, from which the survey stands out. The shaped body base area, which is defined for example by the upper side, can take on a wide variety of geometric shapes in the context of the present invention, from the triangle over the rectangle and its special case, the square up to 5, 6 or 8-cornered shapes. Circular or ellipsoidal shapes are also preferred mold base areas. Other surface shapes, such as stars or animal shapes, can be realized without problems as a shaped body base. Preferred detergent tablets are characterized in that the tablet base is substantially rectangular and preferably has rounded corners. The shaped body itself is therefore preferably cuboid, starting from the underlying shaped body base surface, but other shaped body shapes such as cubes, spheres, wedge-like shapes, egg-shaped forms, etc. are conceivable without any problem.
Die Erhebung, die sich von der Oberseite des Formkörpers abhebt, kann in jeder beliebigen Größe realisiert werden. Aus Gründen der Stabilität und der Optik der resultierenden Formkörper beträgt die Höhe der Erhebung, gemessen als kürzeste Entfernung zwischen der durch die Oberseite des Formkörpers definierten Bezugsebene und dem Punkt der Erhebung, der senkrecht zu dieser Bezugsebene die weiteste Distanz aufweist, 0,2 mm bis 10 mm, vorzugsweise 0,8 bis 5 mm. Das Volumen der Erhebung kann dabei 1/300 bis 1/3, vorzugsweise 1/50 bis 1/5, bezogen auf das gesamte Formkörpervolumen, betragen. Zu bemerken ist noch, dass aus produktionstechnischen und stabilitätsbedingten Gründen die Seitenwände der Erhebung nicht zwingend im 90°-Winkel zur Formkörperoberseite und der Oberseite der Erhebung stehen müssen. Auch die Übergänge zwischen den verschiedenen Flächen können bevorzugt eher abgerundete Ecken und Kanten aufweisen.The survey, which stands out from the top of the molding, can be realized in any size. For reasons of stability and appearance of the resulting molded articles, the elevation height, measured as the shortest distance between the reference plane defined by the upper surface of the molded article and the point of elevation having the widest distance perpendicular to this reference plane, is 0.2 mm 10 mm, preferably 0.8 to 5 mm. The volume of the survey can be 1/300 to 1/3, preferably 1/50 to 1/5, based on the total molding volume. It should also be noted that for production-related and stability-related reasons, the side walls of the survey need not necessarily be in the 90 ° angle to the top of the molding and the top of the survey. The transitions between the different surfaces may preferably have more rounded corners and edges.
Zu der Erhebung, die eine exponierte, bevorzugt planare Fläche umfasst, kann noch erläuternd ergänzt werden, dass diese Erhebung eine Art Reliefstruktur bildet, die bei der Aufsicht auf die / dem Ertasten der exponierte(n) planare(n) Fläche in ihren bevorzugten Ausführungsformen formmäßig so ausgestaltet ist, dass die oben angesprochenen Buchstaben, Produktbezeichnungen, Firmenlogos oder ausschmückenden Ornamente erkennbar und/oder ertastbar sind.To the survey, which includes an exposed, preferably planar area, it can be further explained that this survey forms a kind of relief structure, which is in the supervision of the palpation of the exposed planar surface (s) in its preferred embodiments is designed formally so that the above-mentioned letters, product names, company logos or decorating ornaments are recognizable and / or tactile.
In bevorzugten Ausführungsformen der Erfindung ist die exponierte "planare" Fläche zu einer Bezugsebene des Formkörpers planparallel, wobei eine Bezugsebene vorzugsweise durch die Unterseite oder Oberseite des Formkörpers oder durch wenigstens eine zu den Formkörperseitenflächen orthogonal stehende Ebene definiert wird.In preferred embodiments of the invention, the exposed "planar" surface is plane-parallel to a reference plane of the molded article, wherein a reference plane is preferably defined by the underside or top of the molded article or by at least one plane orthogonal to the molded article side surfaces.
In einer bevorzugten Ausführungsform der Erfindung unterscheidet sich die exponierte planare Fläche zum Zwecke der besseren Erkennbarkeit farblich vom übrigen Formkörper. Um diesen Effekt zu erzielen, kann die exponierte planare Fläche zum Beispiel mit einer Farbstoff und/oder Pigmente enthaltenden Zusammensetzung eingefärbt oder beschichtet sein.In a preferred embodiment of the invention, the exposed planar surface differs in color from the rest of the molded body for better visibility. To achieve this effect, the exposed planar surface may be colored or coated with, for example, a composition containing dye and / or pigments.
Bezüglich der Form des Wasch- oder Reinigungsmittelformkörpers der vorliegenden Erfindung ist noch zu bemerken, dass Vertiefungen, gemessen von einer Ober- oder Unterseite oder Seitenfläche des Formkörpers nicht vorgesehen sind. Damit ist jedoch nicht gemeint, dass keine Vertiefungen innerhalb der Erhebung, die sich von der Oberseite des Formkörpers abhebt, vorgesehen sind. Vielmehr können Vertiefungen innerhalb der Erhebung dann notwendig sein, wenn die aufgebrachte Kennzeichnung so ausgestaltet werden soll, dass bestimmte Formen erkennbar sind. Die Vertiefungen auf der Gesamtfläche der Erhebung reichen dabei jedoch nicht so tief, dass sie eine Vertiefung innerhalb des Formkörpers, gemessen ab der Formkörperoberseite, einschließen.With respect to the shape of the detergent tablets of the present invention, it should also be noted that depressions measured from a top or bottom or side surface of the tablet are not provided. However, this does not mean that no depressions are provided within the elevation, which stands out from the top of the molding. Rather, depressions within the survey may be necessary if the applied label is to be designed so that certain shapes are recognizable. However, the depressions on the total area of the elevation do not extend so deep that they include a depression within the shaped body, measured from the top of the molded body.
Mit dem Begriff "nicht allseitig an den Rand des Formkörpers reichend" soll ausgedrückt werden, dass eine Erhebung als solche erkennbar ist und etwa eine Mulde nicht dadurch zu einer Erhebung uminterpretiert wird, dass die Oberseite des Formkörpers als Erhebung und der tiefste Punkt der Mulde als Oberseite des Formkörpers definiert wird. Mit anderen Worten: eine Erhebung auf dem Formkörper ist nur dann eine Erhebung im Sinne der vorliegenden Erfindung, wenn eine Oberseite, von der sich die Erhebung erhebt, erkennbar ist, wobei sich diese Oberseite zumindest teilweise am Rand des Formkörpers zeigt. Ausdrücklich wird in diesem Zusammenhang darauf hingewiesen, dass sich die hier beschriebenen Formkörper von einer Muldentablette gerade dadurch unterscheidet, dass ausgehend von der Oberfläche des Formkörpers keine Vertiefung vorliegt, sondern eine Erhebung, z.B. in Form einer Reliefstruktur.By the term "not reaching all sides of the edge of the molding" is to be expressed that a survey is recognizable as such and about a trough is not thereby reinterpreted to a survey that the top of the molding as elevation and the lowest point of the trough as Top of the molding is defined. In other words, a survey on the molding is only a survey within the meaning of the present invention, when an upper side from which rises the survey is recognizable, with this top shows at least partially at the edge of the molding. It is expressly stated in this context that the The shaped body described here differs from a mortar tablet precisely in that, starting from the surface of the shaped body, there is no depression, but rather an elevation, for example in the form of a relief structure.
In weiteren Ausführungsformen der Erfindung kann der Formkörper auf mindestens einer weiteren seiner Seiten, vorzugsweise seiner Unterseite, eine Erhebung wie sie oben beschrieben wurde aufweisen. In diesem Fall sind die jeweiligen Definitionen, z.B. die Definition der "Oberseite", entsprechend zu verwenden.In further embodiments of the invention, the molding on at least one other of its sides, preferably its underside, a survey as described above have. In this case, the respective definitions, e.g. the definition of the "top" to use accordingly.
Die Wasch- oder Reinigungsmittelformkörper der vorliegenden Erfindung werden hergestellt durch an sich bekanntes Verpressen einer Wasch- bzw. Reinigungsmittelzusammensetzung, enthaltend Gerüststoffe sowie einen oder weitere Inhaltsstoffe von Wasch- bzw. Reinigungsmitteln, mit der Neuerung, dass entweder der Oberstempel oder der Unterstempel der Presse eine Vertiefung mit einer solchen Form aufweist, so dass durch das Verpressen ein Wasch-oder Reinigungsmittelformkörper gebildet wird, der auf wenigstens einer seiner Oberflächen eine bevorzugt planare Erhebung aufweist.The detergent tablets of the present invention are prepared by compressing a detergent composition containing builders as well as one or more ingredients of detergents, with the innovation that either the top punch or the bottom punch of the press a Groove having such a shape, so that by pressing a washing or cleaning agent molded body is formed, which has a preferably planar elevation on at least one of its surfaces.
Die Herstellung der erfindungsgemäßen Formkörper erfolgt z. B. in bekannter Weise zunächst durch das trockene Vermischen der Bestandteile, die ganz oder teilweise vorgranuliert sein können, und anschließendes Verpressen zu Tabletten, wobei die Vorgemische in einer sog. Matrize zwischen zwei Stempeln zu einem festen Komprimat verdichtet werden. Dieser Vorgang, der nachfolgend kurz als Tablettierung bezeichnet wird, gliedert sich in vier Abschnitte: Dosierung, Verdichtung (elastische Verformung), plastische Verformung und Ausstoßen.The production of the shaped body according to the invention is carried out for. B. in a known manner, first by the dry mixing of the ingredients, which may be pre-granulated in whole or in part, and then pressing into tablets, wherein the premixes are compressed in a so-called. Matrize between two punches to a solid Komprimat. This process, hereinafter referred to as tableting, is divided into four sections: dosing, compaction (elastic deformation), plastic deformation and ejection.
Die Tablettierung erfolgt in handelsüblichen Tablettenpressen, die prinzipiell mit Einfach- oder Zweifachstempeln ausgerüstet sein können. Im letzteren Fall wird nicht nur der Oberstempel zum Druckaufbau verwendet, auch der Unterstempel bewegt sich während des Pressvorgangs auf den Oberstempel zu, während der Oberstempel nach unten drückt. Je nach Produktionsmengen können z. B. Exzenter-Tablettenpressen oder Rundlauf-Tablettenpressen verwendet werden. Das Tablettieren kann bei Umgebungstemperatur oder oberhalb davon ausgeführt werden, was zu einer höheren Festigkeit bei geringerem Verdichtungsdruck führen kann. Im Allgemeinen wird die teilchenförmige Waschmittelzusammensetzung einem Verdichtungsdruck von mindestens 2.500 kN/m2, bevorzugter mindestens 4.000 kN/m2 ausgesetzt. Der maximal bei der Herstellung von Waschmitteltabletten der vorliegenden Erfindung verwendete Verdichtungsdruck beträgt weniger als 400.000 kN/m2.The tabletting is carried out in commercial tablet presses, which can be equipped in principle with single or double punches. In the latter case, not only the upper punch is used for pressure build-up, also the lower punch moves to the upper punch during the pressing process, while the upper punch presses down. Depending on the production quantities z. As eccentric tablet presses or rotary tablet presses can be used. Tableting may be carried out at ambient temperature or above, which may lead to higher strength at lower compaction pressure. In general, the particulate detergent composition is subjected to a compaction pressure of at least 2,500 kN / m 2 , more preferably at least 4,000 kN / m 2 . The maximum compaction pressure used in the manufacture of detergent tablets of the present invention is less than 400,000 kN / m 2 .
Wie erwähnt, kann die teilchenförmige Wasch- oder Reinigungsmittelzusammensetzung, die verdichtet wird, ein Gemisch von Teilchen aller Wasch-oder Reinigungsmittelzusammensetzungs-Bestandteile sein, oder aber auch Teilchen umfassen, die selbst ein Gemisch von Bestandteilen enthalten. Solche Teilchen, die ein Gemisch von Bestandteilen enthalten, können beispielsweise durch ein Granulierungsverfahren oder Sprühtrocknungsverfahren hergestellt werden. Diese Granulate können beispielsweise ein oder mehrere Tenside, Gerüststoffe und/oder andere Reinigungs- oder Waschmittelbestandteile enthalten. Vorzugsweise hat die teilchenförmige Zusammensetzung eine mittlere Teilchengröße im Bereich von 100 bis 2.000 µm, bevorzugter 250 bis 1.400 µm. Obwohl die teilchenförmige Ausgangszusammensetzung im Prinzip jede Schüttdichte aufweisen kann, ist die vorliegende Erfindung besonders geeignet für Formkörper, die bevorzugt aus Teilchen mit relativ hoher Schüttdichte hergestellt werden. Somit kann die teilchenförmige Ausgangszusammensetzung geeigneterweise eine Schüttdichte von mindestens 400 g/l, vorzugsweise mindestens 600 g/l aufweisen.As mentioned, the particulate detergent composition which is compressed may be a mixture of particles of all detergent or cleaning composition components, or may comprise particles which themselves contain a mixture of ingredients. Such particles containing a mixture of ingredients can be prepared by, for example, a granulation process or a spray drying process. These granules may contain, for example, one or more surfactants, builders and / or other cleaning or detergent ingredients. Preferably, the particulate composition has an average particle size in the range of 100 to 2000 microns, more preferably 250 to 1400 microns. Although the particulate starting composition may in principle have any bulk density, the present invention is particularly suitable for shaped articles which are preferably made from particles of relatively high bulk density. Thus, the particulate starting composition may suitably have a bulk density of at least 400 g / l, preferably at least 600 g / l.

Um zu erreichen, dass sich die exponierte planare Fläche der erfindungsgemäßen Wasch- oder Reinigungsmittelformkörper wie oben beschrieben farblich zum Zwecke der besseren Erkennbarkeit vom übrigen Formkörper unterscheidet, können verschiedene Verfahren angewendet werden.In order to achieve that the exposed planar surface of the detergent tablets according to the invention as described above differs in color from the rest of the tablet for better visibility, various methods can be used.
So kann gemäß einer Ausführungsform der Erfindung das oben beschriebene allgemeine Verfahren zur Herstellung der erfindungsgemäßen Wasch- oder Reinigungsmittelformkörper so modifiziert werden, dass vor dem Einfüllen der Wasch- bzw. Reinigungsmittelzusammensetzung in die Presse eine Farbstoff und/oder Pigmente enthaltende Zusammensetzung in die Vertiefung des Unterstempels gegeben wird, so dass zumindest eine der exponierten planaren Flächen der gegebenenfalls mehreren Erhebungen des herzustellenden Wasch- oder Reinigungsmittelformkörpers eingefärbt wird. Bei der Farbstoff und/oder Pigmente enthaltenden Zusammensetzung handelt es sich vorzugsweise um eine flüssige Farbstoffzusammensetzung, die während des Verpressens in die sich verdichtende Wasch- bzw. Reinigungsmittelzusammensetzung eindringt und so zu einer Anfärbung der Erhebung, die die exponierte planare Fläche einschließt, führt. Die Eindringtiefe in die Wasch- bzw. Reinigungsmittelzusammensetzung ist dabei unerheblich, so lange die exponierte planare Fläche der Erhebung vollständig eingefärbt ist.Thus, according to one embodiment of the invention, the above-described general process for the preparation of the detergent tablets according to the invention can be modified so that prior to loading the detergent composition into the press a dye and / or pigment-containing composition in the recess of the lower punch is given, so that at least one of the exposed planar surfaces of the optionally more surveys of the produced laundry detergent or cleaning product is dyed. The composition containing the dye and / or pigment is preferably a liquid dye composition which penetrates into the densifying detergent composition during compression and thus results in staining of the elevation which includes the exposed planar area. The penetration depth into the detergent or cleaning composition is insignificant, as long as the exposed planar surface of the survey is completely colored.
Weitere erfindungsgemäße Verfahren sehen vor, dass nach dem Verpressen der Wasch- bzw. Reinigungsmittelzusammensetzung der Wasch-oder Reinigungsmittelformkörper der Presse entnommen und zumindest eine der exponierten planaren Flächen des Formkörpers mit einer Farbstoff und/oder Pigmente enthaltenden Zusammensetzung eingefärbt oder beschichtet wird. Bei diesen Verfahren erfolgt die farbliche Kennzeichnung der exponierten planaren Fläche also nicht bereits während des Herstellungsprozesses des Wasch- oder Reinigungsmittelformkörpers wie oben beschrieben, sondern erst, wenn der Formkörper an sich bereits fertiggepresst ist und der Presse entnommen wurde.Further processes according to the invention provide that after the washing or cleaning agent composition has been pressed, the washing or cleaning agent molding is removed from the press and at least one of the exposed planar surfaces of the molding is dyed or coated with a composition containing dye and / or pigments. In these methods, the color coding of the exposed planar surface is thus not already during the manufacturing process of the detergent or cleaning product as described above, but only when the molded body is already finished in itself and was removed from the press.
In einer Ausführungsform dieses Verfahrens erfolgt die Einfärbung oder Beschichtung der exponierten planaren Fläche(n) dadurch, dass zumindest eine der exponierten planaren Flächen der gegebenenfalls mehreren Erhebungen in eine Farbstoff und/oder Pigmente enthaltenden Zusammensetzung eingetaucht wird. Dabei wird die Eintauchtiefe so gewählt, dass zumindest die exponierte planare Fläche der jeweiligen Erhebung eingefärbt wird. Eine größere Eintauchtiefe kann jedoch auch gewählt werden, so lange nur die Erhebung eingetaucht wird und nicht Teile des übrigen Formkörpers, insbesondere nicht die Oberseite des Formkörpers, von der aus sich die Erhebung abhebt. Dies soll gewährleisten, dass sich die exponierte planare Fläche farblich zum Zwecke der besseren Erkennbarkeit vom übrigen Formkörper unterscheidet.In one embodiment of this method, the coloring or coating of the exposed planar area (s) is carried out by immersing at least one of the exposed planar areas of the composition, optionally including a plurality of elevations, in a dye and / or pigment-containing composition. The immersion depth is chosen so that at least the exposed planar surface of the respective survey is colored. However, a larger immersion depth can also be chosen, as long as the survey is immersed and not parts of the rest of the molding, in particular not the top of the molding, from which the survey stands out. This is to ensure that the exposed planar surface differs in color from the rest of the molded article for better visibility.
Die Zusammensetzung, in die zumindest die exponierte planare Fläche der Erhebung wie oben beschrieben eingetaucht wird, kann dabei flüssig, pulverförmig oder granular sein. Sie kann auch in Form einer Paste oder eines Gels vorliegen. Vorzugsweise wird eine flüssige, gelförmige oder pastöse Farbstoff und/oder Pigmente enthaltende Zusammensetzung verwendet.The composition, in which at least the exposed planar surface of the elevation is immersed as described above, may be liquid, powdery or granular. It may also be in the form of a paste or a gel. Preferably, a composition containing liquid, gel or pasty dye and / or pigments is used.
Gemäß einer alternativen Ausführungsform erfolgt die Einfärbung oder Beschichtung dadurch, dass eine Farbstoff und/oder Pigmente enthaltende Zusammensetzung, die vorzugsweise flüssig ist, durch Aufstreichen mittels einer Bürste, eines Pinsels oder einer pinselartigen Vorrichtung auf zumindest eine der exponierten planaren Flächen der gegebenenfalls mehreren Erhebungen erfolgt.According to an alternative embodiment, the coloring or coating takes place in that a composition containing dye and / or pigments, which is preferably liquid, is applied to at least one of the exposed planar surfaces of possibly several elevations by brushing, brush or brush-type device ,
In einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens erfolgt die Einfärbung oder Beschichtung dadurch, dass eine Farbstoff und/oder Pigmente enthaltende Zusammensetzung, die vorzugsweise flüssig ist, mittels einer Farbwalze oder eines Druckstempels auf zumindest eine der exponierten planaren Flächen der gegebenenfalls mehreren Erhebungen aufgetragen wird. Dabei ist es bevorzugt, dass der Kontakt zwischen Farbwalze bzw. Druckstempel und der jeweiligen exponierten planaren Fläche elastisch erfolgt, um die Formkörpererhebungen bzw. den Formkörper selbst durch die Druckeinwirkung nicht zu beschädigen oder zu zerstören. Die Elastizität kann dadurch erzielt werden, dass elastische Mittel mit der Farbwalze bzw. dem Druckstempel verbunden sind. Solche elastischen Mittel können z. B. mit der Farbwalze bzw. dem Druckstempel verbundene Federn sein, oder es kann sich um elastische Materialien handeln, die direkt auf der Farbwalzenoberfläche bzw. auf der Druckstempeloberfläche angebracht sind oder zumindest unterhalb dieser Farbwalzen- bzw. Druckstempeloberflächen angeordnet sind, wenn z. B. ein farbübertragendes Gewebevlies oder sonstiges Material auf dem elastischen Material aufgebracht ist. Der elastische Kontakt zwischen Farbwalze bzw. Druckstempel und der jeweiligen exponierten planaren Fläche kann auch mit Hilfe elektrischer, pneumatischer oder hydraulischer Vorrichtungsmittel erfolgen.In a further embodiment of the method according to the invention, the coloring or coating is carried out by applying a dye and / or pigment-containing composition, which is preferably liquid, by means of an ink roller or a printing stamp on at least one of the exposed planar surfaces of the optionally multiple surveys. It is preferred that the contact between the inking roller or plunger and the respective exposed planar surface is elastic to the mold body surveys or the moldings themselves by the pressure not to damage or destroy. The elasticity can be achieved by connecting elastic means to the inking roller or the pressure stamp. Such elastic means may e.g. B. associated with the ink roller or the plunger springs, or it may be elastic materials which are mounted directly on the ink roller surface or on the plunger surface or at least below these Farbwalzen- or plunger surfaces are arranged when z. As a color-transmitting fabric fleece or other material is applied to the elastic material. The elastic contact between ink roller or plunger and the respective exposed planar surface can also be done by means of electrical, pneumatic or hydraulic device means.
Elastische Materialien können thermoplastische Elastomere und Copolymere und Blends von Elastomeren, thermoplastischen Elastomeren und Kautschuken sein.Elastic materials can be thermoplastic elastomers and copolymers and blends of elastomers, thermoplastic elastomers and rubbers.
In einer weiteren Ausführungsform der Erfindung erfolgt die Einfärbung oder Beschichtung dadurch, dass die Farbstoff und/oder Pigmente enthaltende Zusammensetzung mittels eines Textilgewebes, welches mit der Zusammensetzung getränkt ist bzw. wird und welches von mindestens zwei Rollen hinund her oder umlaufend bewegt wird, aufgetragen wird. Dabei wird die Elastizität des Drucks des getränkten Textilgewebes auf die exponierte planare Fläche der Erhebung(en) dadurch bewirkt, dass das Textilgewebe zwischen den Rollen gespannt wird. Über die Höhe der Spannung und die Art des verwendeten Textilgewebes kann die Elastizität gesteuert werden.In a further embodiment of the invention, the coloring or coating is carried out by applying the composition containing the dye and / or pigments by means of a textile fabric which is impregnated with the composition and which is moved back and forth or revolving by at least two rollers , The elasticity of the pressure of the impregnated textile fabric on the exposed planar surface of the survey (s) is effected by the textile fabric is stretched between the rollers. The amount of tension and the type of fabric used can be used to control elasticity.
Anstelle eines Textilgewebes kann auch eine Bahn aus z. B. Filz, Schaumstoff, Samt oder fellartigen Materialien verwendet werden. Diese Materialien können auch bei den weiter oben beschriebenen Varianten mit Farbwalze oder Druckstempel für deren jeweilige Oberfläche verwendet werden.Instead of a textile fabric and a web of z. As felt, foam, velvet or fur-like materials are used. These materials can also be used in the variants described above with ink roller or plunger for their respective surface.
