Description

Die Erfindung richtet sich auf eine Wach-, Spül-oder Reinigungsmittelmehrkomponentenverpakkung zum direkten Einsatz in Wasch-, Spül- oder Reinigungsmaschinen, bestehend aus einem Aussenbeutel zur Aufnahme zumindest einer ersten Produktkomponente und mindestens eines weiteren innenliegenden Körpers zur Aufnahme mindestens einer weiteren Produktkomponente, wobei der zumindest eine innenliegende Körper ein frei beweglicher, mit der zumindest einen weiteren Produktkomponente gefüllter Innenbeutel aus zunächst produktundurchlässiger, aber bei einer vorgegebenen Temperatur wasserlöslicher Folie ist.The invention relates to a multi-component washing, rinsing or cleaning agent package for direct use in washing machines, dishwashers or cleaning machines, consisting of an outer bag for holding at least one first product component and at least one further internal body for holding at least one further product component, the at least one internal body is a freely movable inner bag, which is filled with the at least one further product component and is initially made of film which is impermeable to the product but is water-soluble at a predetermined temperature.

In zunehmenden Masse werden Wasch-, Spül-und Reinigungsmittel entwickelt und gebraucht, die während der Anwendung im maschinellen Prozess zu einem ganz bestimmten Zeitpunkt ihre Wirkung entfalten sollen. Hierbei ist es aus Gründen der Arbeitsersparnis erwünscht, diese Produkte dem Waschprozess oder dergleichen von Anfang an und nicht erst zum vorgesehenen Zeitpunkt - gegebenenfalls bei Unterbrechung des maschinellen Ablaufs - zuzugeben.Detergents, dishwashing detergents and cleaning agents are being developed and used to an increasing extent and are intended to develop their effect at a very specific point in time during use in the machine process. In order to save labor, it is desirable to add these products to the washing process or the like from the beginning and not only at the intended time - if necessary, if the machine process is interrupted.

Eine Mehrkomponentenverpackung der eingangs genannten Art ist aus der US=A-4115 292 bekannt. Bei dieser Verpackung ist es jedoch von Nachteil, dass hier ein wasserlöslicher Aussenbeutel vorgesehen ist, der zunächst wasser- und produktundurchlässig ist und erst infolge des Auflösungsvorganges des Aussenbeutels beim Entstehen eines ersten Loches wasser-und produktdurchlässig wird. Dadurch ist eine kontinuierliche und dosierte Produktabgabe durch den Aussenbeutel nicht gewährleistet. Beim Entstehen eines ersten Loches gelangt schlagartig Wasser in den Aussenbeutel und führt dort zu Verklumpungen des Reinigungsmittels. Desweiteren sind die Materialien für wasserlösliche Folien so flexibel und von so geringer Eigensteifigkeit, dass derartige Aussenbeutel leicht verformbar sind und die Gefahr besteht, dass sie sich beispielsweise beim Waschen an den Innenflächen der Waschmaschine, z. B. am Maschinenbullauge der Waschmaschine, festsetzen und der Beutel nicht weiter mit der Wäsche mitbewegt wird.A multi-component packaging of the type mentioned at the outset is known from US = A-4115 292. With this packaging, however, it is disadvantageous that here a water-soluble outer bag is provided, which is initially impermeable to water and product and only becomes water-permeable and product-permeable as a result of the dissolution process of the outer bag when a first hole is created. As a result, continuous and metered product delivery through the outer bag is not guaranteed. When a first hole is created, water suddenly gets into the outer bag and clumps the detergent there. Furthermore, the materials for water-soluble films are so flexible and of such low inherent stiffness that such outer bags are easily deformable and there is a risk that they will stick to the inner surfaces of the washing machine, e.g. B. on the machine porthole of the washing machine, fix and the bag is not moved with the laundry.

Ferner sind aus der FR-A-2 358 499 und der EP-A-0011 501 von Anfang an wasser- und produktdurchlässige Waschmittelpackungen bekannt.Furthermore, from FR-A-2 358 499 and EP-A-0011 501, water and product-permeable detergent packs have been known from the start.

Die FR-A-2 358 499 beschreibt eine Einkomponentenverpackung für ein festes oder granulat- bis pulverförmiges Avivagemittel, welche zumindest bereichsweise eine aus zwei porösen Schichten bestehende Doppelwand aufweist, die das Avivagemittel zum grössten Teil bis gegen Ende des Waschprozesses oder bis zum Einsetzen eines Trockenprozesses zurückhält. Hier soll das Avivagemittel nur allmählich und zu Beginn des Waschprozesses nach Möglichkeit so gut wie gar nicht durch die poröse Doppelwand austreten. Dieser Packung haftet zum einen der Nachteil an, dass sie aufgrund der speziell ausgebildeten Doppelwand nur sehr aufwendig herzustellen ist und zum anderen ein gleich zu Beginn des Waschprozesses einsetzender gleichmässiger Produktaustrag aus dem Verpackungsbeutel nicht gewährleistet ist.FR-A-2 358 499 describes a one-component packaging for a solid or granular to powdery finishing agent, which at least in some areas has a double wall consisting of two porous layers, the majority of the finishing agent until the end of the washing process or until the start of a drying process holds back. Here, the finishing agent should only emerge gradually through the porous double wall and, if possible, hardly at the beginning of the washing process. On the one hand, this pack has the disadvantage that, due to the specially designed double wall, it is very difficult to manufacture and, on the other hand, it is not guaranteed that the product will be evenly discharged from the packaging bag at the start of the washing process.

Aus der EP-A-0011 501 ist ein poröser Verpakkungsbeutel aus wasserunlöslichem Material bekannt, der gegebenenfalls aus mehreren Kammern bestehen kann. Hierbei sind die einzelnen Kammern aber fest miteinander verbunden, was einen erhöhten Aufwand bei der Befüllung des Verpackungsbeutels mit verschiedenen Komponenten mit sich bringt. Ebenso besteht auch bei diesem Verpackungsbeutel die Gefahr, dass sich der Beutel im Anwendungsfalle aufgrund der Flexibilität seines Materiales an den Innenflächen einer Waschmaschine festsetzt.A porous packaging bag made of water-insoluble material is known from EP-A-0011 501, which can optionally consist of several chambers. In this case, however, the individual chambers are firmly connected to one another, which entails an increased outlay when filling the packaging bag with various components. Likewise with this packaging bag there is also the risk that the bag will stick to the inner surfaces of a washing machine due to the flexibility of its material.

Eine weitere Verpackung wird in «Die neue Verpackung» 10/1962, 1150-1155 beschrieben. Der das Produkt aufnehmende, wasserlösliche Beutel kann beispielsweise aus PVAL (Polyvinylalkohol) hergestellt werden. Je nach Materialzusammensetzung und Herstellungsweise kann die Temperatur der Wasserlöslichkeit der Folie vorbestimmt werden (vgl. Hoechst, Informationen aus der Anwendungstechnik, August 1980, 31-41). Problematisch und leicht fehlerbehaftet wird die Anwendung, wenn mehrere Komponenten entweder zeitlich nacheinander anzuwenden sind oder aber miteinander beim Lagern unverträgliche Komponenten zugleich einzusetzen sind. In solchen Fällen müssen entsprechend viele verschiedene Einzelverpackungen bereitgehalten und in der jeweils passenden Rezeptur dem Wasch-, Spül-oder Reinigungsprozess zugegeben werden.Another packaging is described in "The new packaging" 10/1962, 1150-1155. The water-soluble pouch holding the product can be made, for example, from PVAL (polyvinyl alcohol). Depending on the material composition and production method, the temperature of the water solubility of the film can be predetermined (see Hoechst, Information from Application Technology, August 1980, 31-41). The application becomes problematic and prone to errors if several components are either to be used one after the other in time or components which are incompatible with one another during storage are to be used simultaneously. In such cases, a correspondingly large number of different individual packagings must be kept ready and added to the washing, rinsing or cleaning process in the appropriate formulation.

Aufgabe der Erfindung ist die Schaffung einer Mehrkomponentenverpackung für Wasch-, Spül-oder Reinigungsmittel, die dem Wasch-, Spül-oder Reinigungsprozess von Anfang an zugegeben werden kann und die das Wirksamwerden einer ersten Produktkomponente unmittelbar bei Wasserkontakt zu Beginn des Wasch-, Spül- oder Reinigungsprozesses ermöglicht, weitere Produktkomponenten jedoch erst in Abhängigkeit von einer vorgegebenen Waschwassertemperatur zu einem späteren Zeitpunkt freisetzt, wobei eine im wesentlichen gleichmässige und kontinuierliche Produktkomponentenabgabe aus der Verpackung gewährleistet ist. Weiterhin soll sich die Mehrkomponentenverpackung durch eine gewisse Eigensteifigkeit auszeichnen und leicht befüllbar sein.The object of the invention is to provide a multi-component packaging for washing, rinsing or cleaning agents, which can be added to the washing, rinsing or cleaning process from the start and which makes the first product component effective immediately upon contact with water at the start of washing, rinsing. or cleaning process enables, but only releases further product components at a later time depending on a predetermined wash water temperature, whereby an essentially uniform and continuous delivery of product components from the packaging is guaranteed. Furthermore, the multi-component packaging should have a certain inherent rigidity and be easy to fill.

Diese Aufgabe wird bei einer Mehrkomponentenverpackung der eingangs genannten Art dadurch gelöst, dass der Aussenbeutel aus einer wasser- und produktdurchlässigen, offenporigen Polyurethanschaumfolie mit Materialrückstellvermögen besteht.This object is achieved in the case of a multi-component packaging of the type mentioned at the outset in that the outer bag consists of a water-permeable and product-permeable, open-pore polyurethane foam film with material resilience.

Aufgrund der Verwendung einer offenporigen Polyurethanschaumfolie mit Materialrückstellvermögen für den Aussenbeutel wird ein Festsetzen der Verpackung auf der Innenfläche des jeweiligen Wasch-, Spül- oder Reinigungsgerätes, z.B. am Maschinenbullauge einer Waschmaschine, verhindert. Es wird dadurch sichergestellt, dass beispielsweise beim Waschen die Waschmittel-Due to the use of an open-pored polyurethane foam film with material resilience for the outer bag, the packaging is prevented from sticking to the inner surface of the respective washing, rinsing or cleaning device, for example on the machine porthole of a washing machine. This ensures that, for example, the detergent

portion mit ihren Zusätzen zusammen mit der Wäsche pulsiert und rotiert. Dadurch, dass der Aussenbeutel während des gesamten Waschvorganges erhalten bleibt, wird weiterhin das gleichmässige und kontinuierliche Austreten der freigesetzten und bei in den Aussenbeutel gelangtem Wasser gelösten Produktkomponenten gewährleistet. Insbesondere tritt auch die sich zunächst in dem Innenbeutel befindende Produktkomponente nach Auflösung der Innenbeutelfolie nicht schlagartig aus der Packung aus, sondern strömt allmählich durch den äusseren Verpackungsbeutel aus. Die erfindungsgemässe Mehrkomponentenverpakkung ist ohne grossen technischen Aufwand herstellbar und leicht mit unterschiedlichen Produktkomponenten befüllbar.portion with its additives pulsates and rotates together with the laundry. The fact that the outer bag is retained during the entire washing process ensures that the released and released product components are released evenly and continuously when water gets into the outer bag. In particular, the product component initially located in the inner bag does not suddenly emerge from the package after the inner bag film has dissolved, but rather gradually flows out through the outer packaging bag. The multi-component packaging according to the invention can be produced without great technical outlay and can be easily filled with different product components.

Das Behandlungsmittel ist im Rahmen der Erfindung im allgemeinen Wasser; grundsätzlich bezieht sich die Erfindung aber auf beliebige, mit der jeweiligen Produktkomponente zu versetzende Behandlungsmittel auch dann, wenn lediglich Wasser, Wasserlöslichkeit oder Wasserdurchlässigkeit erwähnt werden.In the context of the invention, the treatment agent is generally water; in principle, however, the invention relates to any treatment agent to be mixed with the respective product component even if only water, water solubility or water permeability are mentioned.

Weiterhin sieht die Erfindung vor, dass der Aussenbeutel mindestens zwei bei unterschiedlicher Temperatur wasserlösliche- und/oder mit unterschiedlichen Komponenten gefüllte Innenbeutel enthält.Furthermore, the invention provides that the outer bag contains at least two inner bags that are water-soluble at different temperatures and / or filled with different components.

Durch die Erfindung wird demgemäss eine beutelartige Verpackung geschaffen, die aus einem Aussenbeutel und mindestens einem darin eingesetzten Innenbeutel besteht. Der Aussenbeutel soll packstoffbezogen wasser- und produktdurchlässig sein, während für den oder die Innenbeutel Wasserlöslichkeit bei jeweils bestimmt vorgegebener Temperatur vorgesehen wird. Beispielsweise kann der aus wasser- und produktdurchlässigem Packstoff gebildete Aussenbeutel mit pulverförmigem Waschmittel gefüllt werden und einen oder mehrere Innenbeutel aufnehmen, die aus warm- oder kaltwasserlöslicher PVAL-Folie bestehen und eine zweite Produktkomponente, z. B. in Pasten-, Pulver-, Tabletten- oder Flüssigform, enthalten.The invention accordingly creates a bag-like packaging which consists of an outer bag and at least one inner bag inserted therein. The outer bag should be permeable to water and product in relation to the packaging material, while water solubility is provided for the inner bag (s) at a predetermined temperature. For example, the outer bag formed from water- and product-permeable packaging material can be filled with powdered detergent and can hold one or more inner bags, which consist of warm or cold water soluble PVAL film and a second product component, e.g. B. in paste, powder, tablet or liquid form.

Beim Einsatz wird das unmittelbar im Aussenbeutel befindliche Produkt in der Regel sofort nach dem Wasserzulauf aufgelöst sowie bei Vorhandensein einer Bewegung «ausgewalkt» und feinverteilt der Waschflotte oder dergleichen zugeführt. Die erfindungsgemässe Verpackung kann dabei auch für unterschiedliche Produkte angewendet werden, die gemeinsam gleichzeitig einzusetzen sind aber aus bestimmten Gründen bei Transport und Lagerung getrennt aufbewahrt werden sollen. Der jeweilige Innenbeutel kann dann aus im Wasserzulauf, insbesondere in kaltem Wasser, löslicher Folie bestehen. Soll die Zugabe des Inhalts eines oder mehrerer Innenbeutel erst bei Erreichen einer bestimmten Wassertemperatur erfolgen, wird das Folienmaterial des jeweiligen Beutels bei seiner Herstellung bereits entsprechend eingestellt. Am Ende des jeweiligen Wasch-, Spül- oder Reinigungsprozesses wird in der Regel - voraussetzungsgemäss - nichts mehr von den Innenbeuteln zu finden sein. Demgegenüber verbleibt der geleerte Aussenbeutel bei entsprechender Beschaffenheit in der Maschine und kann zusammen mit dem behandelten Gut entnommen (und in der Regel weggeworfen) werden.When in use, the product directly in the outer bag is usually dissolved immediately after the water supply and, in the presence of a movement, “rolled out” and finely divided and fed to the wash liquor or the like. The packaging according to the invention can also be used for different products which are to be used together at the same time but, for certain reasons, are to be kept separate during transport and storage. The respective inner bag can then consist of film which is soluble in the water inlet, in particular in cold water. If the content of one or more inner bags is only to be added when a certain water temperature is reached, the film material of the respective bag is already set accordingly during its manufacture. At the end of the respective washing, rinsing or cleaning process, as a rule - according to the prerequisite - nothing more can be found from the inner bags. In contrast, the emptied outer bag remains of a suitable nature in the machine and can be removed (and usually thrown away) together with the treated goods.

Anhand der schematischen Darstellung von Ausführungsbeispielen werden weitere Einzelheiten der Erfindung erläutert. Es zeigen:

  • Fig. 1 den Querschnitt einer Mehrkomponentenverpackung mit einem Innenbeutel; und
  • Fig. 2 den Querschnitt einer Mehrkomponentenverpackung mit zwei Innenbeuteln.
Further details of the invention are explained on the basis of the schematic representation of exemplary embodiments. Show it:
  • Figure 1 shows the cross section of a multi-component packaging with an inner bag. and
  • Fig. 2 shows the cross section of a multi-component packaging with two inner bags.

Die in den Fig. 1 und 2 im Schnitt dargestellten Mehrkomponentenverpackungen können Einsatz finden in Wasch-, Spül- oder sonstigen Reinigungsmaschinen. Die Verpackung nach Fig. 1 besteht aus einem Aussenbeutel 1 aus offenporigem PUR-Schaumstoff als wasserdurchlässigem Packstoff und einem Innenbeutel, z.B. aus PVAL-Folie, wobei der Aussenbeutel mit einer ersten Produktkomponente, z. B. mit pulverförmigem Produkt 3, und der Innenbeutel 2 mit einer zweiten Produktkomponente 4 gefüllt sein sollen. Die zweite Produktkomponente 4 kann in Form von Pulver, Tabletten, wasserfreier Paste oder Flüssigkeit vorliegen. Der Aussenbeutel 1 und der Innenbeutel 2 können teilweise oder ganz mit dem jeweiligen Produkt 3 bzw. 4 gefüllt werden. Durch Vorgabe des Füllungsgrades kann dem Produkt und dessen Aufgabe entsprechend die Wirkungsweise der Verpackung hinsichtlich Zurückhaltung und Abgabe der fraglichen Komponente unterstützt werden. Die Nähte 5 bzw. 6 des Aussenbeutels und Innenbeutels werden vorzugsweise verschweisst. Je nach dem ob das im Innenbeutel 2 enthaltene Produkt 4 zugleich mit dem im Aussenbeutel 1 enthaltenen Produkt 3 oder zu einem späteren Zeitpunkt bzw. bei einer anderen Aussentemperatur freigegeben werden soll, wird das Material des Innenbeutels 2 ausgewählt. Beispielsweise kann der Innenbeutel 2 aus kaltwasserlöslicher oder aus bei bestimmter Temperatur warmwasserlöslicher PVAL-Folie bestehen. Während das PUR-Material des Aussenbeutels 1 eine relativ grosse Wandstärke von z. B. 2 mm haben kann, soll die Folie des Innenbeutels 2, die bei Anwendung in der Regel völlig aufzulösen ist, nur eine Stärke von z. B. grössenordnungsmässig 25 Mikrometern aufweisen.The multi-component packaging shown in section in FIGS. 1 and 2 can be used in washing machines, dishwashers or other cleaning machines. The packaging according to Fig. 1 consists of an outer bag 1 made of open-pore PUR foam as a water-permeable packaging material and an inner bag, e.g. made of PVAL film, the outer bag containing a first product component, e.g. B. with powdered product 3, and the inner bag 2 should be filled with a second product component 4. The second product component 4 can be in the form of powder, tablets, anhydrous paste or liquid. The outer bag 1 and the inner bag 2 can be partially or completely filled with the respective product 3 or 4. By specifying the degree of filling, the mode of operation of the packaging with regard to retention and dispensing of the component in question can be supported according to the product and its task. The seams 5 and 6 of the outer bag and inner bag are preferably welded. The material of the inner bag 2 is selected depending on whether the product 4 contained in the inner bag 2 is to be released at the same time as the product 3 contained in the outer bag 1 or at a later time or at a different outside temperature. For example, the inner bag 2 can consist of PVAL film that is soluble in cold water or hot water soluble at a certain temperature. While the PUR material of the outer bag 1 has a relatively large wall thickness of z. B. may have 2 mm, the film of the inner bag 2, which is usually completely dissolve when used, only a thickness of z. B. order of magnitude 25 microns.

In dem Aussenbeutel 1 können nach Fig. 2 auch mehrere Innenbeutel 2, 2' mit unterschiedlichem Produktinhalt 4, 4' enthalten sein. Beispielsweise kann der Aussenbeutel 1 ebenso wie nach Fig. 1 aus wasserdurchlässigem Packstoff bestehen und mit der ersten Produktkomponente 3 gefüllt werden. Für die Innenbeutel 2, 2' ergeben sich dann viele Variationen. Beispielsweise kann der Innenbeutel 2 aus kaltwasserlöslicher PVAL-Folie bestehen und mit einer zugleich mit der ersten Komponente 3 dem Waschvorgang oder dergleichen zuzugebenden zweiten Komponente 4 gefüllt werden, während der Innenbeutel 2' eine dritte Komponente 4' aufnimmt, der erst bei einer höheren Temperatur, z.B. 40°C, und/oder zu einem späteren Zeitpunkt hinzuzufügen ist und daher beispielsweise aus einem erst bei der höheren Temperatur wasserlöslichen Material herzustellen ist. Alternativ können die Innenbeutel 2 und 2' auch aus Folien hergestellt werden, die bei verschiedenen Temperaturen, z. B. bei 40 °C und 75 °C, warmwasserlöslich sind, so dass der Beutelinhalt dem jeweiligen Behandlungsprozess selbsttätig genau dann hinzugefügt wird, wenn die umgebende Flotte gerade die erforderliche Temperatur erreicht hat.2, a plurality of inner bags 2, 2 'with different product contents 4, 4' can also be contained in the outer bag 1. For example, as in FIG. 1, the outer bag 1 can consist of water-permeable packaging material and can be filled with the first product component 3. There are then many variations for the inner bags 2, 2 '. For example, the inner bag 2 can consist of cold water-soluble PVAL film and can be filled with a second component 4 which is to be added to the washing process or the like at the same time as the first component 3, while the inner bag 2 'holds a third component 4' which is only at a higher temperature, eg 40 ° C, and / or to be added at a later time and therefore, for example, from a higher temperature temperature to produce water-soluble material. Alternatively, the inner bags 2 and 2 'can also be produced from foils which are used at different temperatures, e.g. B. at 40 ° C and 75 ° C, hot water soluble, so that the bag content is automatically added to the respective treatment process exactly when the surrounding liquor has just reached the required temperature.
