Abstract

The invention relates to a method for dosing pre-portioned textile detergents which are packed in bags made of a water-soluble film. Said bags are introduced into a dimensionally stable, preferably round, reclosable hollow body, which on one side in its outer wall has one or more permanent openings (4). After closing of the hollow body the bags, in this form and undergoing a movement, are brought into contact with the water which serves to produce the lye. Arranging the openings in the hollow body on one side only permits a very even distribution of the detergent in the lye. According to a special version of the invention the hollow body also has a perforated separating wall (5) inside it. The method is especially well suited for dosing viscous, gel-like or paste-like detergents.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Dosierung von Waschmitteln bei der Wäsche von Textilien im Haushalt und im gewerblichen Bereich, bei dem die Waschmittel in vorportionierter Form eingesetzt werden.The present invention relates to a method for dosing detergents in the washing of textiles in the household and in the commercial sector, in which the detergents are used in pre-portioned form.

Waschmittel oder Waschhilfsmittel werden heute bei den üblichen Textilwaschverfahren in der Weise dosiert, daß man diese Mittel dem zuströmenden Wasser zufügt oder sie vom zuströmenden Wasser in die eigentlichen Waschbehälter einspülen läßt. Da es hierbei zu Schwierigkeiten verschiedenster Art kommen kann, ist als Alternative, insbesondere für die Wäsche in Trommelwaschmaschinen, vorgeschlagen worden, die Waschmittel oder Waschhilfsmittel in einzelnen Portionen in Beuteln verpackt direkt in den Waschraum zu geben, wo sich das Wandmaterial der Beutel entweder in Wasser vollständig auflöst oder aber die Beutel durch das Wasser oder die sich langsam erhöhende Temperatur geöffnet werden. Schwierigkeiten ergeben sich hierbei durch die Tatsache, daß beim Öffnen des Beutels der Beutelinhalt in konzentrierter Form auf eine kleine Stelle eines Textilstücks einwirken kann und auf diese Weise, vor allem bei farbigen Textilien, ungewollte fleckförmige Aufhellungen oder zumindest ungleichmäßige Wirkungen zu beobachten sind. Dies gilt in ganz besonderem Maße für gelförmige und pastenförmige Waschmittel. Bei einer anderen Alternative werden die Waschmittelwirkstoffe in der gewünschten Menge in formstabile, poröse Hohlkörper gefüllt und diese Hohlkörper dann zusammen mit dem Textilgut in den Waschbehälter gegeben. Im Laufe der Rotationsbewegung werden die Waschmittelwirkstoffe dann durch die Öffnungen der Hohlkörper hindurch vom Wasser allmählich ausgelaugt. Um ein langsames und möglichst gleichmäßiges Ausströmen der Waschmittelwirkstoffe zu gewährleisten, sind für diesen Zweck Hohlkörper von sehr autwendiger Gestaltung entworfen worden. In jedem Fall ist bei Verwendung dieser wiederbefüllbaren Hohlkörper ein genaues Abmessen der Waschmittelwirkstoffe durch den Verbraucher notwendig.Detergents or washing aids are used today in the usual textile washing processes dosed in such a way that these agents to the inflowing Adds water or it from the inflowing water into the actual wash tank can be flushed in. Because there are difficulties of all kinds as an alternative, especially for washing in drum washing machines, have been proposed to detergents or detergents in individual Portions packed in sachets to give directly to the washroom wherever the wall material of the bags either completely dissolves in water or the bags by the water or the slowly increasing temperature be opened. Difficulties arise from the fact that when opening the bag, the contents of the bag are concentrated in a small form Place of a piece of textile can act and in this way, especially at colored textiles, unwanted blotchy or at least uneven effects can be observed. This is particularly true Dimensions for gel and paste detergents. Another one Alternatively, the detergent ingredients in the desired amount dimensionally stable, porous hollow bodies filled and then these hollow bodies together with the textile goods in the washing container. In the course of the rotational movement then the detergent active ingredients through the openings of the hollow body gradually drained from the water. To be slow and possible Ensure even outflow of the detergent ingredients are for For this purpose, hollow bodies have been designed with a very necessary design. In In any case, when using these refillable hollow bodies, an exact one is Measurement of the detergent ingredients by the consumer necessary.

In diesem Zusammenhang war die Aufgabe zu lösen, ein Dosierverfahren zu finden, daß es einerseits ermöglicht, vorportionierte Waschmittel zu verwenden und dabei die Nachteile einer ungleichmäßigen Wirkung und Schädigungen durch lokale Überdosierung auf den Textilien zu vermeiden. Dieses Verfahren sollte zudem mit möglichst einfachen Mitteln durchführbar sein.In this context, the task to be solved was to find a dosing method that it makes it possible to use pre-portioned detergents while doing so the disadvantages of an uneven effect and damage from local Avoid overdosing on the textiles. This procedure should also include be as simple as possible.

Die EP-A-0 290 332 beschreibt ein Verfahren zur Dosierung von vorportioniertem Textilwaschmittel unter Verwendung eines formstabilen, wieder verschließbaren Hohlkörpers, der in seiner Außenwand einseitig eine oder mehrere bleibende Öffnungen aufweist, wobei der verschlossene Hohlkörper samt Inhalt unter Bewegung mit Wasser, das zur Herstellung der Waschlauge dient, in Kontakt gebracht wird.EP-A-0 290 332 describes a method for dosing pre-portioned Textile detergent using a dimensionally stable, reclosable Hollow body, one or more permanent one-sided in its outer wall Has openings, the closed hollow body with its content below Movement in contact with water used to make the wash liquor brought.

Gegenstand der EP-A-0 780 508 ist ein Dosierspeicher zur Aufnahme und Abgabe eines flüssigen, pastösen oder tablettenförmigen Wäschebehandlungsmittels zur Verwendung in einem mit einer Waschmaschine durchzuführenden Waschverfahrens. Der Dosierspeicher besteht aus einem Topf, verbunden mit einem Deckel, wobei Topf oder Deckel Ein- und Ausströmöffnungen aufweisen.The subject of EP-A-0 780 508 is a dosing store for receiving and dispensing a liquid, pasty or tablet-shaped laundry treatment agent for Use in a washing machine Washing process. The dosing tank consists of a pot connected to a Lid, the pot or lid having inlet and outlet openings.

Die EP-A-0 593 952 beschreibt einen Beutel aus wasserlöslichem Folienmaterial zur Aufnahme von portioniertem Reinigungsmittel für automatische Geschirrspülmaschinen. Die Wasserlöslichkeit des Folienmaterials ist dergestalt, daß das Reinigungsmittel innerhalb des Zeitraums bis zum Beginn des Klarspülens in die Waschflüssigkeit freigesetzt wird. Derartige Beutel werden in die Dosierkammer oder in den Geschirrkorb der Maschine eingelegt.EP-A-0 593 952 describes a bag made of water-soluble film material Inclusion of portioned detergent for automatic Dishwashers. The water solubility of the film material is such that the detergent into the rinse within the time period Washing liquid is released. Such bags are in the metering chamber or placed in the crockery basket of the machine.

Demgegenüber betrifft die vorliegende Erfindung ein Verfahren zur Dosierung von vorportioniertem Textilwaschmittel unter Verwendung eines formstabilen, wiederverschließbaren Hohlkörpers (1, 2), der in seiner Außenwand einseitig eine oder mehrere bleibende Öffnungen (4) aufweist, wobei der verschlossene Hohlkörper samt Inhalt unter Bewegung mit dem Wasser in Kontakt gebracht wird, das zur Herstellung der Waschlauge dient, dadurch gekennzeichnet, daß das Waschmittel portionsweise in einem Beutel aus wasserlöslicher Folie verpackt in den Hohlkörper eingebracht wird. In contrast, the present invention relates to a method for dosing pre-portioned textile detergent using a dimensionally stable, reclosable hollow body (1, 2), the one side in its outer wall or has a plurality of permanent openings (4), the closed hollow body together with its contents is brought into contact with the water while moving Production of the wash liquor is used, characterized in that the detergent packed in portions in a bag made of water-soluble film into the hollow body is introduced.

Das neue Verfahren eignet sich zur Dosierung sowohl von flüssigen als auch von pulverförmigen oder blockförmigen festen Waschmitteln oder Waschhilfsmitteln, besonders gut aber zur Dosierung von zähflüssigen, gelförmigen oder pastösen Waschmitteln. Insbesondere die letztgenannten Waschmittel konnten bisher nur mit Hilfe aufwendiger Vormischgeräte dosiert werden, so daß ihr Einsatz im wesentlichen auf große kontinuierliche Waschmaschinen beschränkt blieb, die eine derartige Investition rechtfertigten.The new method is suitable for dosing both liquid and powdery or blocky solid detergents or washing aids, but particularly good for dosing viscous, gel-like or pasty Detergents. The latter detergents in particular have so far only been able to be metered with the help of complex premixers, so that their use is essentially was limited to large continuous washing machines, one justified such investment.

Bei dem Material, aus dem die Portionsbeutel bestehen, kann es sich prinzipiell um beliebige wasserlösliche folienbildende organische Polymermaterialien handeln. Bevorzugt werden solche Materialien verwendet, die aus ökologischen Gründen unbedenklich mit dem Abwasser abgegeben werden können. Besonders bevorzugt werden deshalb Folien aus Polyvinylalkohol und teilhydrolisiertem Polyvinylacetat, sowie Copolymere von Vinylalkohol mit anderen Monomeren als Vinylacetat und teilhydrolysierte Copolymere von Vinylacetat mit anderen Monomeren als Vinylalkohol. Besonders bevorzugt werden teilhydrolisierte Polyvinylacetate, da durch den Hydrolysegrad die Lösungsgeschwindigkeit der Folie in weiten Grenzen variiert werden kann.In principle, the material from which the sachets are made can be can be any water-soluble film-forming organic polymer materials. Such materials are preferably used, which are from ecological Reasons can be safely discharged with the waste water. Films made of polyvinyl alcohol and partially hydrolyzed polyvinyl acetate, and copolymers of vinyl alcohol with monomers other than vinyl acetate and partially hydrolyzed copolymers of Vinyl acetate with monomers other than vinyl alcohol. Particularly preferred become partially hydrolyzed polyvinyl acetates, because of the degree of hydrolysis Solution speed of the film can be varied within wide limits.

Auch die Form des Beutels und die Dicke des verwendeten Folienmaterials lassen sich in weiten Grenzen variieren, so daß das öffnungsverhalten der Beutel in weiten Bereichen vorbestimmt werden kann.Also the shape of the bag and the thickness of the film material used can be varied within wide limits, so that the opening behavior of the Bags can be predetermined in wide areas.

Bei dem wiederverschließbaren Hohlkörper, der zur Aufnahme des portionsweise verpackten Wasch- oder Waschhilfsmittels dient, handelt es sich um einen formstabilen Hohlkörper, der in seiner Außenwand einseitig eine oder mehrere Öffnungen aufweist. Formstabil heißt in diesem Zusammenhang, daß sich der Hohlkörper während des Waschvorgangs in der Waschmaschinentrommel unter den dort auftretenden Kräften und Bedingungen praktisch nicht verformt. Vorzugsweise sollte der Hohlkörper keine scharfen äußeren Ecken und Kanten aufweisen, die beim ständigen Umwälzen des Hohlkörpers zusammen mit den Textilien in der Waschtrommel zu einer Beschädigung empfindlicher Textilien führen könnten. Das heißt, daß beispielsweise Würfel, Tetraeder oder Quader in der herkömmlichen Form im erfindungsgemäßen Verfahren vorzugsweise nicht verwendet werden sollen, wohl aber derartige Körper, deren Ecken und Kanten nur soweit abgerundet sind, daß die ursprüngliche Form des Körpers noch erkennbar bleibt. Besonders bevorzugt werden Hohlkörper verwendet, die keine ebenen Außenflächen besitzen und insbesondere solche, die im wesentlichen Kugelform aufweisen. Der Hohlkörper soll mindestens eine wiederverschließbare Öffnung aufweisen, die so groß sein muß, daß die Beutel, in denen sich das Waschmittel oder Waschhilfsmittel befindet, ohne Mühe in das Innere des Hohlkörpers eingelegt werden können. Im einfachsten Fall kann diese Öffnung nach Einlegen des Beutels durch einen wasserfest klebenden Klebestreifen verschlossen werden. Vorzugsweise wird der Hohlkörper aber aus zwei oder gegebenenfalls mehreren Teilen bestehen, die jeweils zueinander passende reversibel wirksame Verbindungselemente aufweisen, die es gestatten, die Teile nach dem Eintrag des Waschmittels wieder zum Hohlkörper zusammenzufügen. So kann der Hohlkörper beispielsweise mit einem einschraubbaren Deckel versehen sein oder mit einem Deckel, der durch einen Schnappmechanismus auf dem anderen Teil des Hohlkörpers befestigt werden kann. Vorzugsweise besteht der Hohlkörper aus zwei annähernd gleich großen Teilen, die reversibel zusammengefügt werden können. Besonders bevorzugt ist es, einen Hohlkörper zu verwenden, der aus zwei miteinander beweglich verbundenen Teilen besteht, die in der vorbeschriebenen Weise zum Schließen und Öffnen des Hohlkörpers zusammengefügt und wieder getrennt werden können. Diese bewegliche Verbindung kann beispielsweise aus einer Kette, einem Schamier oder einem gleichwirkenden elastischen Plastikband bestehen.In the case of the reclosable hollow body, which is used to accommodate the portions packaged washing or washing aids, it is a dimensionally stable Hollow body with one or more openings on one side in its outer wall having. Dimensionally stable in this context means that the hollow body during the washing process in the washing machine drum under the Forces and conditions occurring there are practically not deformed. Preferably the hollow body should not have any sharp outer corners and edges have, which during constant circulation of the hollow body together with the Textiles in the washing drum to damage delicate textiles could lead. This means that, for example, cubes, tetrahedra or cuboids in the conventional form in the process according to the invention is preferably not should be used, but probably such bodies, their corners and edges are only rounded to the extent that the original shape of the body is still remains recognizable. Hollow bodies which do not have any particular preference are used have flat outer surfaces and in particular those which are essentially Have spherical shape. The hollow body should be at least one resealable Have opening that must be so large that the bags in which the Detergent or washing aids is easily inside the Hollow body can be inserted. In the simplest case, this opening can after inserting the bag with a waterproof adhesive tape be closed. However, the hollow body is preferably composed of two or if necessary, consist of several parts, each matching one another Have reversibly effective fasteners that allow the parts after the detergent has been added to the hollow body. For example, the hollow body can have a screw-in cover be provided or with a lid that is opened by a snap mechanism the other part of the hollow body can be attached. Preferably there is the hollow body consists of two parts of approximately the same size, which are reversible can be put together. It is particularly preferred to have a hollow body to use, which consists of two movably connected parts, which in the manner described above for closing and opening the hollow body can be put together and separated again. This agile Connection can for example consist of a chain, a hinge or a equivalent elastic plastic tape exist.

Wesentliches Merkmal des formstabilen, wiederverschließbaren Hohlkörpers ist das Vorhandensein von einer oder vorzugsweise mehreren bleibenden Öffnungen in seiner Außenwand, wobei diese Öffnungen einseitig angebracht sein sollen. Die Bezeichnung "einseitig" setzt in diesem Fall nicht das Vorhandensein einer echten Seite und damit eines eckigen Körpers voraus, sondern soll hier nur bedeuten, daß der Körper gedanklich durch eine Trennfläche so in zwei gleichgewichtige Teile geteilt werden kann, daß sich auf einer der beiden entstehenden Seiten mehr Öffnungen befinden als auf der anderen. Diese Öffnungen sind permanent vorhanden und deutlich kleiner als die Einfüllöffnung des Hohlkörpers, so daß ein Austreten des unveränderten Beutels aus diesen Öffnungen nicht möglich ist. Durch diese Öffnungen sollen Wasser und Waschlauge durch die Außenwand des Hohlkörpers strömen können, wobei die Strömungsgeschwindigkeit durch Zahl und Größe der Öffnungen in weiten Grenzen bestimmt werden kann. Vorzugsweise sollen diese Öffnungen so angebracht werden, daß sich alle diese Öffnungen auf einer Seite des Hohlkörpers befinden. Die Form der Öffnungen kann weitgehend frei gestaltet werden. Die Größe des Hohlkörpers wird so gewählt, daß sein Innenraum von dem Beutel, der die für einen Waschgang benötigte Menge an Waschmittel beziehungsweise Waschhilfsmittel enthält, zu weniger als 90 %, vorzugsweise zu weniger als 75 % und insbesondere zu weniger 50 % aber vorzugsweise zu mehr als 20 % ausgefüllt wird.An essential feature of the dimensionally stable, reclosable hollow body is the presence of one or preferably more permanent ones Openings in its outer wall, these openings being made on one side should be. The term "one-sided" does not set this in this case Presence of a real side and thus an angular body ahead, but should only mean here that the body is mentally represented by a Partition surface can be divided into two equal parts so that on one of the two emerging sides has more openings than on the others. These openings are permanent and significantly smaller than that Filling opening of the hollow body, so that an escape of the unchanged bag is not possible from these openings. Water should pass through these openings and wash liquor can flow through the outer wall of the hollow body, wherein the flow velocity by the number and size of the openings in wide Limits can be determined. These openings should preferably be like this be attached that all these openings on one side of the Hollow body. The shape of the openings can largely be freely designed become. The size of the hollow body is chosen so that its interior of the sachet that contains the amount of detergent required for a wash cycle or contains washing aids, to less than 90%, preferably to less than 75% and in particular less than 50% but preferably more is filled in as 20%.

Im erfindungsgemäßen Verfahren wird der mit dem Waschmittelbeutel gefüllte und wiederverschlossene Hohlkörper unter Bewegung mit dem Wasser in Kontakt gebracht, das zur Herstellung der Waschlauge dient. Bei der bevorzugten Anwendung in Trommelwaschmaschinen wird der Hohlkörper mit dem Textilgut in die Waschtrommel gegeben und dort vom zuströmenden Wasser und später während des Waschvorgangs von der Waschlauge erreicht. Das durch die Öffnungen in den Hohlkörper eingedrungene Wasser verläßt diesen wegen der einseitigen Anordnung der Öffnungen nicht sofort wieder, sondern wird zunächst im Hohlkörper, bedingt durch dessen Bewegung in der Waschtrommel, umgewälzt. Im Kontakt mit dem eingedrungenen Wasser löst sich das Wandmaterial des Beutels auf und gibt den Inhalt des Beutels ebenfalls für die Auflösung im Wasser frei. Durch den verzögerten Austausch des im Hohlkörpers befindlichen Wassers bzw. der Waschmittellösung mit dem umgebenden Wasser erfolgt die Abgabe des Waschmittels in die Waschflotte allmählich und damit sehr gleichmäßig. Ein direkter Kontakt zwischen dem unverdünnten Waschmittel und dem Textil wird vermieden. Durch Wahl der Öffnungsanzahl und der Öffnungsgrößen kann die Abgabegeschwindigkeit des Waschmittels unter Berücksichtigung seiner Löslichkeit und der Wassertemperatur in weiten Grenzen den Bedürfnissen des Waschprozesses angepaßt werden. Diese Vorteile zeigen sich in besonderem Maße bei Verwendung von pulverförmigen, zähflüssigen, gelförmigen oder pastösen Waschmitteln als Beutelinhalt.In the method according to the invention, the one filled with the detergent pouch and reclosed hollow bodies moving with the water in Bring contact that is used to produce the wash liquor. In the preferred application in drum washing machines is the hollow body with put the textile in the washing drum and there from the inflowing Water and later reached by the wash liquor during the washing process. The water that has entered the hollow body through the openings leaves not immediately because of the one-sided arrangement of the openings, but is first in the hollow body, due to its movement in the Washing drum, circulated. Solves in contact with the ingressed water the wall material of the bag and also gives the contents of the bag free for dissolution in water. Due to the delayed exchange of the im Hollow body water or the detergent solution with the surrounding water, the detergent is released into the wash liquor gradually and therefore very evenly. A direct contact between the undiluted detergent and the textile is avoided. By choosing the The number of openings and the size of the openings can reduce the delivery speed of the Detergent taking into account its solubility and the Water temperature adapted to the needs of the washing process within wide limits become. These advantages are particularly evident when used of powdery, viscous, gel or pasty detergents as Bag contents.

Zur besseren Steuerung der verzögerten Löslichkeit weist der erfindungsgemäß verwendete Hohlkörper in einer besonderen Ausführungsform in seinem Inneren eine perforierte Trennwand auf, die so angebracht ist, daß sein Innenraum in zwei Teile aufgeteilt wird, von denen derjenige, in den das im Beutel befindliche Waschmittel eingebracht wird, durch eine Außenwand des Hohlkörpers begrenzt wird, die weniger Öffnungen aufweist als die Außenwand, die den anderen Teil des Innenraums begrenzt. In einer besonders bevorzugten Variante dieser Ausführungsform wird der Raumteil, der das Waschmittel aufnimmt, durch eine Außenwand ohne Öffnungen begrenzt. Bei dieser Ausführungsform dringt das Wasser in den Hohlkörper vorzugsweise zunächst in den Teil ein, der kein Waschmittel enthält, und gelangt erst von dieser Vorkammer durch die perforierte Trennwand an das im Beutel befindliche Waschmittel. Dadurch ist es möglich, nicht nur durch die Zahl, die Größe und die Anordnung der Öffnungen in der Außenwand des Hohlkörpers, sondern auch durch die Art der Perforierung in der Trennwand die Auflösegeschwindigkeit zu steuem. Die Trennwand kann dabei fest mit dem Hohlkörper verbunden sein oder aber auch in auswechselbarer Form im Hohlkörper angebracht sein. Vorzugsweise ist die Trennwand mit dem Teil des Hohlkörpers fest verbunden, der nicht zur Aufnahme des Beutels bestimmt ist. Dieser Teil umfaßt vorzugsweise 20 bis 50 % des Hohlkörperinhalts. Für den Füllgrad des anderen Hohlkörperteils mit Waschmittel gelten die oben für den Hohlkörper ohne Trennwand angegebenen Verhältnisse entsprechend. Die Perforierung der Trennwand kann im einfachsten Fall aus ein oder mehreren kleinen Öffnungen bestehen, die isoliert angebracht sein können oder aber siebähnlich oder gitterähnlich ausgeführt sein können. Auch hier bestimmen Zahl und Größe der Öffnungen die Durchströmgeschwindigkeit und damit den Verzögerungseffekt bei der Auflösung des Waschmittels in der Waschlauge. Das Zusammenwirken von perforierter Trennwand im Inneren des Hohlkörpers mit der einseitigen Anbringung der Öffnungen in dessen Außenwand führt zu einer besonders gleichmäßigen Verteilung des Waschmittels in der Waschlauge.For better control of the delayed solubility, the invention has used hollow body in a special embodiment in its interior a perforated partition, which is attached so that its interior in is divided into two parts, one of which is the one in the bag Detergent is introduced, limited by an outer wall of the hollow body which has fewer openings than the outer wall, the other part of the interior limited. In a particularly preferred variant of this embodiment the part of the room that holds the detergent is replaced by a Outer wall limited without openings. In this embodiment, it penetrates Water in the hollow body preferably first in the part that has no Contains detergent, and only gets from this antechamber through the perforated Partition to the detergent in the bag. This makes it possible not just by the number, size and arrangement of the openings in the Outer wall of the hollow body, but also by the type of perforation in the Partition to control the dissolution rate. The partition can do this be firmly connected to the hollow body or alternatively Form be attached in the hollow body. Preferably, the partition with the Part of the hollow body firmly connected, which does not hold the bag is determined. This part preferably comprises 20 to 50% of the hollow body content. The above applies to the degree of filling of the other hollow part with detergent the hollow body according to the specified conditions. The In the simplest case, perforation of the partition can consist of one or more there are small openings that can be attached isolated or else can be designed like a screen or like a grid. Here too, numbers determine and size of the openings the flow rate and thus the Delay effect in the dissolution of the detergent in the wash liquor. The Interaction of perforated partition inside the hollow body with the one-sided attachment of the openings in its outer wall leads to a particularly even distribution of the detergent in the wash liquor.

Der Formkörper kann aus beliebigem formstabilen Material hergestellt werden, soweit dieses Material unter den obengenannten Bedingungen bruch- und korrosionsfest ist. So kann der Hohlkörper prinzipiell ganz oder teilweise aus Metall oder Keramik geformt sein, doch wird für seinen Herstellung vorzugsweise Kunststoff verwendet. Besonders bevorzugt werden Kunststoffe, die die Herstellung des Hohlkörpers im Spritzgußverfahren erlauben, insbesondere Polyvinylchlorid (PVC), Polyethylen (PE) und Polypropylen (PP). Von diesen Werkstoffen wird Polypropylen besonders bevorzugt. Bei Bedarf können aber auch die einzelnen Teile des Hohlkörpers aus verschiedenen Materialien gefertigt werden.The molded body can be made from any dimensionally stable material, insofar as this material is unbreakable and corrosion-resistant under the conditions mentioned above is. In principle, the hollow body can be made entirely or partially of metal or ceramic, but plastic is preferably used for its manufacture used. Plastics are particularly preferred, which are the production allow the hollow body in the injection molding process, in particular polyvinyl chloride (PVC), polyethylene (PE) and polypropylene (PP). Of these materials Polypropylene particularly preferred. If necessary, the individual can also Parts of the hollow body are made of different materials.

Abbildung 1 zeigt in schematisierter Form einen erfindungsgemäß verwendbaren Hohlkörper in Form einer Hohlkugel, bestehend aus zwei annähernd gleich großen Teilen (1, 2), die mit einem elastischen Band (3) beweglich verbunden sind. Das obere der beiden Hohlkugelteile (1) besitzt in seiner Außenwand Öffnungen (4), die im erfindungsgemäßen Verfahren, das Ein- und Ausströmen von Wasser bzw. Waschlauge erlauben. Das untere Teil (2) der Hohlkugel besitzt keine derartigen Öffnungen in seiner Außenwand. Abbildung 1 zeigt die Hohlkugel in aufgeklappter Form; beim Zuklappen der Kugel wird über einen hier nicht gezeigten Rastmechanismus der reversible Zusammenhalt der beiden Hohlkugelteile gewährleistet.Figure 1 shows in a schematic form a usable according to the invention Hollow body in the form of a hollow sphere, consisting of two approximately the same size Parts (1, 2) which are movably connected with an elastic band (3). The upper of the two hollow spherical parts (1) has openings in its outer wall (4) in the process according to the invention, the inflow and outflow of water or allow wash liquor. The lower part (2) of the hollow ball has no such Openings in its outer wall. Figure 1 shows the hollow sphere in the opened position Shape; when the ball is closed, one is not shown here Locking mechanism ensures the reversible cohesion of the two hollow ball parts.

Abbildung 2 zeigt einen erfindungsgemäß verwendbaren Hohlkörper, der sich vom Hohlkörper der Abbildung 1 durch das Vorhandensein einer perforierten Trennwand (5) in seinem Inneren unterscheidet. Im vorliegenden Fall ist die perforierte Trennwand (5) fest und ringsum schließend mit dem Teil (1) der Hohlkugel verbunden, das in seiner Außenwand die Öffnungen (4) trägt. Das zweite Teil (2) der Hohlkugel ist zur Aufnahme des oder der Waschmittelbeutel bestimmt. Auch in Abbildung 2 wird die Hohlkugel in aufgeklappter Form gezeigt, wobei auch hier ein nicht gezeigter Rastmechanismus dafür sorgt, daß nach dem Zusammenklappen beide Kugelhälften reversibel und für den Waschvorgang ausreichend fest miteinander verbunden sind.Figure 2 shows a hollow body which can be used according to the invention and which is separated from the hollow body of Figure 1 by the presence of a perforated partition (5) in differentiates its inside. In the present case, the perforated partition is (5) firmly and all around with the part (1) of the hollow ball connected in its outer wall carries the openings (4). The second part (2) of the hollow sphere is intended to hold the detergent pouch or pouches. Also in Figure 2 the hollow sphere is shown in an unfolded form, although here too a not locking mechanism shown ensures that after folding both Ball halves reversible and sufficiently firm for the washing process are connected.

Das erfindungsgemäße Verfahren umfaßt auch solche Varianten, bei denen nicht die gesamte für den Waschgang notwendige Waschmittelmenge in einem einzigen Beutel enthalten ist, sondern diese Waschmittelmenge auf mehrere Beutel verteilt ist, die dann gemeinsam in einen Hohlkörper eingelegt oder auf mehrere Hohlkörper verteilt werden. Die obengenannten Volumenverhältnisse im Innenraum des Hohlkörpers gelten dann für die Gesamtheit der aufgenommenen Beutel. Bei dieser Variante können die einzelnen Beutel gleichen Inhalt haben, wenn beispielsweise wegen besonders starker Verschmutzung eine doppelte oder dreifache Dosierung des Waschmittels gewünscht wird. Die einzelnen Beutel können aber auch unterschiedliche Waschmittelwirkstoffe enthalten, wenn beabsichtigt ist, einzelne Wirkstoffe nur bei besonderen Waschgängen einzusetzen, bei anderen hingegen nicht. Auf diese Art und Weise kann die Zusammensetzung der Waschlauge vom Verbraucher in weiten Grenzen selbst gesteuert werden. Die Unterbringung von einzelnen Waschmittelbestandteilen in getrennten Beuteln ermöglicht es auch, miteinander chemisch unverträgliche Substanzen, die nicht zusammen gelagert werden können, gemeinsam in einem Waschbad einzusetzen. Dabei besteht auch die Möglichkeit, durch Wahl verschieden schnell löslicher Folienmaterialien für einzelne Beutelinhaltsstoffe eine stärkere Lösungsverzögerung als für die Inhaltsstoffe anderer Beutel einzustellen. Das erfindungsgemäße Verfahren ist damit äußerst vielseitig für sämtliche Waschmittelwirkstoffe einzeln ebenso wie für Zubereitungen von Waschhilfsmitteln und vollständigen Waschmitteln aus mehreren Wirkstoffen geeignet. In allen Fällen führt das erfindungsgemäße Verfahren mit äußerst einfachen Hilfsmitteln zu einer genau steuerbaren Auflösung der Waschmittelwirkstoffe und zu ihrer optimalen Verteilung in der Waschlauge. Dabei werden die Vorteile der portionsweisen Verpackung genutzt, gleichzeitig aber die Nachteile einer örtlichen Überdosierung vermieden. The method according to the invention also includes those variants in which not the total amount of detergent required for the wash cycle in one Bag is included, but this amount of detergent on multiple bags is distributed, which is then placed together in a hollow body or in several Hollow bodies are distributed. The above volume ratios in the interior of the hollow body then apply to the entirety of the bags received. In this variant, the individual bags can have the same content, if for example because of particularly heavy pollution, a double or triple dosage of the detergent is desired. The individual bags but can also contain different detergent ingredients if the intention is to use individual active ingredients only in special wash cycles to use, but not with others. In this way, the The composition of the wash liquor by the consumer within wide limits to be controlled. The placement of individual detergent components in separate pouches also allows chemically incompatible with each other Substances that cannot be stored together in one Use a washing bath. There is also the option of choosing film materials that dissolve at different speeds for individual bag ingredients a greater delay in dissolution than for the contents of other bags adjust. The method according to the invention is therefore extremely versatile for all detergent ingredients individually as well as for preparations by Washing aids and complete detergents from several active ingredients suitable. In all cases, the method according to the invention is extremely effective simple tools for a precisely controllable resolution of the Detergent ingredients and their optimal distribution in the wash liquor. The advantages of portion-wise packaging are used at the same time but avoided the disadvantages of local overdosing.

Beispielexample

Das erfindungsgemäße Verfahren wurde in einer gewerblichen Trommelwaschmaschine mit einem pastenförmigen, Bleichmittel enthaltenden Vollwaschmittel durchgeführt. Das Waschmittel war in Schlauchbeuteln aus Polyvinylalkohol in Portionen von 170 g abgepackt. Pro Wäsche wurde 1 Beutel in einen kugelförmigen Hohlkörper eingebracht und dieser Hohlkörper dann zu der zu waschenden Wäsche in die Waschtrommel vor Beginn des Waschprozesses eingelegt.The inventive method was in a commercial drum washing machine with a pasty detergent containing bleach carried out. The detergent was in polyvinyl alcohol tubular bags packed in 170 g portions. 1 bag per wash introduced a spherical hollow body and then this hollow body to the laundry to be washed in the washing drum before starting the washing process inserted.

Der kugelförmige Hohlkörper bestand aus zwei gleich großen Halbkugeln aus Polyethylen, die mit einem Kunststoffschamier beweglich miteinander verbunden waren und mit Hilfe eines Nut-Feder-Mechanismus reversibel verschlossen werden konnten. Zum leichteren Öffnen und Schließen des Hohlkörpers waren auf der Außenseite auf beiden Kugelhälften auf der dem Scharnier gegenüberliegenden Seite noppenförmige Erhebungen angebracht. In der oberen Halbkugel war entsprechend Abbildung 3 eine perforierte Zwischenwand fest und randschlüssig so angebracht, daß sie ein Kugelsegment abtrennte, das etwa 40 % des Kugelvolumens umfaßte. Die Außenwand dieses abgetrennten Kugelteils wies 50 kreisförmige Löcher mit einem Durchmesser von 4 mm auf. In der Trennwand befanden sich 30 kreisförmige Löcher mit einem Durchmesser von 2 mm. Die Außenwand der unteren Halbkugel wies keine Öffnungen auf. Die Wandstärke des Hohlkörpers betrug etwa 2 mm, der äußere Durchmesser 80 mm.The spherical hollow body consisted of two hemispheres of the same size Polyethylene that is movably connected with a plastic hinge goods and can be reversibly closed using a tongue and groove mechanism could. For easier opening and closing of the hollow body were on the outside on both halves of the ball on the opposite side of the hinge Side knob-shaped elevations attached. Was in the upper hemisphere according to Figure 3, a perforated partition wall with a tight fit attached so that it separated a spherical segment that is about 40% of the spherical volume included. The outer wall of this separated spherical part was 50 circular holes with a diameter of 4 mm. In the partition there were 30 circular holes with a diameter of 2 mm. The The outer wall of the lower hemisphere had no openings. The wall thickness the hollow body was about 2 mm, the outer diameter 80 mm.

Das Waschverfahren war durch folgende Einzelheiten gekennzeichnet: Waschmaschine Elektrolux FLE 120 PE Temperatur der Vorwäsche 45 °C Dauer der Vorwäsche 10 Minuten Temperatur der Hauptwäsche 70 °C Dauer der Hauptwäsche 15 Minuten Zahl der Spülgänge 3 Flottenverhältnis in beiden Waschstufen 1 : 5 Flottenverhältnis in den Spülgängen 1 : 7 Beladung 8,5 kg Buntwäsche The washing process was characterized by the following details: Washing machine Elektrolux FLE 120 PE Prewash temperature 45 ° C Prewash duration 10 mins Main wash temperature 70 ° C Duration of the main wash 15 minutes Number of rinses 3 Fleet ratio in both washing stages 1: 5 Fleet ratio in the rinse cycles 1: 7 loading 8.5 kg colored laundry

Das Waschmittel wies ein spezifisches Gewicht von 1,52 g/cm3 auf und hatte folgende Zusammensetzung:

  • 39,0 Gew.-% nichtionische Tenside in Form eines Gemisches aus Fettalkohol-Ethoxylaten
  • 2,5 Gew.-% anionische Tenside in Form eines Gemisches aus Seife und Phosphorsäureester
  • 15,0 Gew.-% Polycarbonsäure - Natriumsalze
  • 18,0 Gew.-% Natriumperboratmonohydrat
  • 6,0 Gew.-% Tetraacetylethylendiamin
  • 18,3 Gew.-% anorganische Salze
  • 1,2 Gew.-% Enzym und optischer Aufheller
    • The detergent had a specific weight of 1.52 g / cm 3 and had the following composition:
  • 39.0% by weight of nonionic surfactants in the form of a mixture of fatty alcohol ethoxylates
  • 2.5% by weight of anionic surfactants in the form of a mixture of soap and phosphoric acid ester
  • 15.0% by weight of polycarboxylic acid sodium salts
  • 18.0% by weight sodium perborate monohydrate
  • 6.0% by weight tetraacetylethylenediamine
  • 18.3% by weight of inorganic salts
  • 1.2% by weight of enzyme and optical brightener

    • Zur Kontrolle der Waschmittelabgabe aus dem Hohlkörper wurde der Waschvorgang nach der Vorwäsche und nach der Hauptwäsche unterbrochen, der Hohlkörper entnommen und durch Wiegen die noch darin befindliche Waschmittelmenge bestimmt. Es zeigte sich dabei, daß im Vorwaschgang etwa ein Drittel des Waschmittels in Lösung gegangen war und der Rest des Waschmittels im Hauptwaschgang vollständig aus dem Hohlkörper entfernt wurde. Die gespülte Wäsche wurde dann geschleudert, getrocknet und hinsichtlich des Reinigungsergebnisses untersucht:
    Es zeigten sich keinerlei Waschmittelrückstände auf den Textilien; das Reinigungsergebnis an den Textilien war völlig gleichmäßig, und an den farbigen Textilstücken zeigten sich keinerlei fleckförmige Aufhellungen.    To check the detergent release from the hollow body, the washing process after the prewash and after the main wash was interrupted, the hollow body was removed and the amount of detergent still present was determined by weighing. It was found that about a third of the detergent had gone into solution in the prewash cycle and the rest of the detergent was completely removed from the hollow body in the main wash cycle. The rinsed laundry was then spun, dried and examined for the cleaning result:
    There were no detergent residues on the textiles; the cleaning result on the textiles was completely uniform, and there were no spot-shaped lightenings on the colored textile pieces.

    Zum Vergleich wurde das Waschverfahren in der Weise wiederholt, daß die gleiche Menge dieses Waschmittels ebenfalls in einem gleichen Polyvinylalkoholbeutel verpackt unmittelbar der Waschtrommel ohne Verwendung des perforierten Hohlkörpers zugesetzt wurde. Auch in diesem Fall wurde das Waschverfahren nach Beendigung der Vorwäsche und Beendigung der Hauptwäsche jeweils unterbrochen und der Verbleib des Waschmittels festgestellt. Dabei zeigte sich, daß nach dem Vorwaschgang der größte Teil des Waschmittels in Form eines verfestigten Klumpens an einem Textilstück anhaftete. Nach der Hauptwäsche war immer noch ein beträchtlicher Teil des eingesetzten Waschmittels ungelöst und haftete in Form von mehreren kleinen Klümpchen an den Textilien fest. Auch nach dem Spülen, Schleudem und Trocknen der Textilien waren noch Reste des Waschmittels auf den Textilien zu bemerken. Die Reinigung war bereits mit bloßem Auge als ungleichmäßig erkennbar und einige der gefärbten Textilien wiesen fleckförmige Aufhellungen auf.For comparison, the washing procedure was repeated so that the same Amount of this detergent also in an equal polyvinyl alcohol bag immediately packed in the washing drum without using the perforated hollow body was added. In this case too Washing process after completion of the prewash and completion of the Main wash interrupted and the whereabouts of the detergent detected. It was found that after the pre-wash, most of the Detergent in the form of a solidified lump on a piece of textile clung. After the main wash was still a significant part of that Detergent used undissolved and stuck in the form of several small ones Lumps on the textiles. Even after rinsing, spinning and Drying the textiles leftovers of the detergent on the textiles to notice. The cleaning was already uneven with the naked eye recognizable and some of the dyed textiles showed blotchy lightenings on.
