Abstract

In automatic washing machines, washing or rinsing can be carried out with washing or rinsing liquid enriched with a fragrance material. In order to be able to feed fragrance material into the water bath or rinsing bath in a convenient and adequate manner, the fragrance material is fed to the wash or rinsing liquid in the form of a water- soluble or water-dispersing solid containing at least 1 gram of fragrance material, namely as a tablet or capsule of appropriate size, towards the end of the wash process, namely during the last wash cycle or the final rinsing phase. A fragrance additive particularly suitable for this purpose advantageously consists of at least 1 gram of fragrance material and furthermore a water-soluble or water- dispersible, solid fragrance-dispensing body containing filler, carrier or emulsifier, for example in the form of a tablet (1) having a volume of more than 1 cm<3> and a water-tight and gas-tight enveloping layer 2 which encloses the tablet (1) on all sides and can be destroyed by hand. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstel­len von mit Duftstoff anzureichernder Wasch- oder Spüllauge in automatischen Waschmaschinen sowie auf ein zur Durchführung dieses Verfahrens dienendes Duftstoffzugabemittel.The invention relates to a method for producing washing or rinsing liquor to be enriched with fragrance in automatic washing machines and to a fragrance addition agent used to carry out this method.

Zum Waschen von textilem Gut in automatischen Waschma­schinen ist es bekannt, dem Waschpulver in geringem Umfang Duftstoffe zuzusetzen, die nach dem Einspülen des Waschpulvers in der Waschlauge ihre Wirkung entfalten und für eine entspre­chende geruchsmäßige Verbesserung des darin befindlichen Waschguts sorgen sollen. Eine ähnliche Wirkung soll auch par­fümierte, als Spülmittel-Zusatz verwendete Avivage herbeifüh­ren. Schließlich ist es auch nicht mehr neu, mit Duftstoffen getränkte Vliese zu verwenden, die nicht nur für das Trocken­schleudern sondern auch für vorhergehende Waschgänge dem zu behandelnden Wasch- bzw. Trockengut beigelegt werden, um des­sen entsprechende Duftverbesserung herbeizuführen. In all die­sen bekannten Fällen bleibt jedoch die mit der Zugabe von Duftstoffen angestrebte Wäscheverbesserung hinter den Erwar­tungen zurück. Das liegt hauptsächlich daran, daß mit den vor­bekannten Methoden immer nur vergleichsweise wenig Duftstoff in die Wasch- oder Spüllauge gelangt und die ohnehin geringen Duftstoffmengen mit dem Wasch- oder Spülwasser rasch fortge­schwemmt bzw. ausgetragen werden, ohne ihre Wirksamkeit auf das Waschgut voll entfaltet zu haben. Hinzu kommt bei der be­ kannten Duftstoffanreicherung als weiterer Nachteil die auf­wendige Herstellung von mit solchen Duftstoffen zu durchset­zenden Waschpulvern und auch die unzureichende Konservierung der darin enthaltenen Duftstoffe. Sobald eine entsprechend ge­füllte Waschpulver-Packung angebrochen ist, können sich die darin enthaltenen Duftstoffe verflüchtigen, wodurch einerseits die Duftstoff-Konzentration im Waschpulver noch weiter zurück­geht und andererseits eine entsprechende, nicht immer als un­bedingt angenehm empfundene Geruchsbelastung der Umgebungsluft eintritt. Bei mit Duftstoffen getränkten Vliesen ist es so, daß diese einigermaßen wirkungsvoll lediglich bei mit getrenn­tem Trockenlaufgang arbeitenden Wasch- bzw. Trockenautomaten sind. Bei mit durchgehenden Wasch- und Trockenprogramm arbei­tenden Waschautomaten müßten dagegen solche duftstoffgetränk­ten Vliese in jedem Fall bereits zu Beginn des Waschprogramms dem in der Maschine vorhandenen Waschgut beigelegt werden. Das aber würde notwendigerweise dazu führen, daß die Duftstoffe während der anschließenden Wasch- und Spülgänge praktisch vollständig ausgespült werden, also nicht im Waschgut selbst verbleiben.For washing textile goods in automatic washing machines, it is known to add a small amount of fragrances to the washing powder, which, after the washing powder has been washed into the washing liquor, have their effect and are intended to provide a corresponding odor-related improvement in the laundry contained therein. A scented finish used as a dishwashing liquid additive is said to have a similar effect. Finally, it is no longer new to use nonwovens impregnated with fragrances, which are added to the items to be treated or dried not only for spin-drying but also for previous wash cycles in order to bring about their corresponding fragrance improvement. In all these known cases, however, the laundry improvement aimed at by adding fragrances falls short of expectations. This is mainly due to the fact that, with the known methods, only comparatively little fragrance gets into the washing or rinsing liquor and the small amounts of fragrance are washed away or carried away quickly with the washing or rinsing water without having fully developed their effectiveness on the laundry . Added to this is the be knew fragrance enrichment as a further disadvantage the complex production of washing powders to be penetrated with such fragrances and also the inadequate preservation of the fragrances contained therein. As soon as an appropriately filled washing powder pack has opened, the fragrances contained therein can evaporate, which on the one hand reduces the fragrance concentration in the washing powder even further and on the other hand results in a corresponding odor load in the ambient air, which is not always perceived as being absolutely pleasant. In the case of fleeces impregnated with fragrances, it is the case that they are somewhat effective only with washing or drying machines which operate with a separate dry cycle. In the case of washing machines working with a continuous washing and drying program, however, such nonwoven fabrics soaked in fragrance would have to be added to the items to be washed in the machine at the beginning of the washing program. However, this would necessarily lead to the fact that the fragrances are virtually completely rinsed out during the subsequent washing and rinsing cycles, that is to say do not remain in the laundry itself.

Der Erfindung liegt die Aufgabe zugrunde, das Herstellen von mit Duftstoff anzureichernder Wasch- oder Spüllauge in au­tomatischen Waschmaschinen wesentlich zu vereinfachen und wirksamer zu gestalten. Diese Aufgabe wird nach der vorliegen­den Erfindung verfahrensmäßig dadurch gelöst, daß der Duft­stoff gegen Ende des Waschprozesses, nämlich während des letz­ten Waschganges oder der abschließenden Spülphase, der Wasch- bzw. Spüllauge in Form eines mindestens ein Gramm Duftstoff enthaltenden, wasserlöslichen oder -dispergierenden Festkör­pers, nämlich als Tablette oder Kapsel entsprechender Größe zugeführt wird. Auf diese Weise kann der Wasch- oder Spüllauge in automatischen Waschmaschinen der Duftstoff in hinreichender Menge und auf einfachste Weise zugeführt werden, indem man da­zu lediglich eine entsprechende Duftstoff-Tablette oder -Kap­sel in das entsprechende Wasch- bzw. Spülpulvervorratsfach des Waschautomaten einlegt, von wo aus die Kapsel oder Tablette mit dem in ihr in vergleichsweise hoher Konzentration enthal­tenen Duftstoff zusammen mit dem entsprechenden Wasch- bzw. Spülmittel in die Wasch- oder Spüllauge eingeschwemmt wird, so daß sich darin der in ausreichendem Umfang vorhandene Duft­stoff entfalten und sich dem Waschgut voll wirksam mitzuteilen bzw. anzulagern vermag.The invention is based, to simplify the production of fragrance-enriched washing or rinsing liquor in automatic washing machines and make it more effective. This object is achieved according to the present invention in that the fragrance towards the end of the washing process, namely during the last wash cycle or the final rinsing phase, the washing or rinsing liquor in the form of a water-soluble or dispersing solid containing at least one gram of fragrance, namely is supplied as a tablet or capsule of the appropriate size. In this way, the washing or rinsing liquor in automatic washing machines can be supplied with the fragrance in sufficient quantity and in the simplest way by simply inserting an appropriate fragrance tablet or capsule into the corresponding washing or rinsing powder storage compartment of the washing machine, from where is washed out of the capsule or tablet with the fragrance contained in it in a comparatively high concentration together with the corresponding detergent or dishwashing detergent into the washing or rinsing solution, so that the fragrance present to a sufficient extent unfold and is able to communicate or add to the laundry fully effectively.

Ein zum erfindungsgemäßen Herstellen von mit Duftstoff anzureichernder Wasch- oder Spüllauge in automatischen Wasch­maschinen dienendes Duftstoffzugabemittel besteht erfindungs­gemäß aus einem mindestens 1 Gramm Duftstoff und im übrigen einen Füll-, Träger- oder Emulgierstoff enthaltenden, in Was­ser löslichen oder dispergierbaren, festen Duftstoffzugabekör­per in Tabletten- oder Kapselform von mehr als 1 cm³ Raumin­halt, der allseits von einer wasser- und gasdichten, von Hand zerstörbaren Umhüllungsschicht umschlossen ist. Ein solcher tabletten- oder kapselförmiger Duftstoffzugabekörper kann be­quem und dauerhaft aufbewahrt werden, da sein wasserlöslicher oder -dispergierbarer, den Duftstoff enthaltender Bestandteil durch die wasser- und gasdichte Umhüllungsschicht wirksam ge­schützt ist. Soll eine solche Duftstoffzugabe-Tablette oder -Kapsel der Waschmaschine zugeführt werden, so braucht dazu lediglich die Umhüllungsschicht zerstört zu werden, was von Hand leicht vorgenommen werden kann. Gleiches gilt für eine entsprechend beschaffene Duftstoffzugabe-Kapsel. Beide Duft­stoffzugabe-Festkörper sind leicht zu handhaben, da sie hin­reichend groß und damit auch gut anfaßbar sind. Das gilt ins­besondere für den Fall, daß die Duftstoffzugabe-Tabletten oder -Kapseln im bevorzugten Falle mehr als 2,5 Gramm Duftstoff enthalten und ein Mindestvolumen von 5 cm³ besitzen. Falls Duftstoffzugabe-Tabletten dieser Größe sich für bestimmte Waschmaschinenautomaten als zu groß bzw. nicht direkt zugabe­geeignet erweisen, könnten die Tabletten mit Sollbruchstellen bildenden Kerbeinschnitten versehen sein und auf diese Weise vor Eingabe in den Waschautomaten von Hand leicht zerkleinert werden.According to the invention, a fragrance addition agent used to produce wash or rinse liquor to be enriched with fragrance in automatic washing machines consists of a fragrance addition body in tablets or containing at least 1 gram of fragrance and, moreover, a filler, carrier or emulsifier which is water-soluble or dispersible Capsule shape with a volume of more than 1 cm³, which is enclosed on all sides by a water and gas-tight coating that can be destroyed by hand. Such a tablet-shaped or capsule-shaped fragrance addition body can be stored conveniently and permanently since its water-soluble or water-dispersible constituent containing the fragrance is effectively protected by the water- and gas-tight coating layer. If such a fragrance addition tablet or capsule is to be fed to the washing machine, all that needs to be done is to destroy the coating layer, which can easily be done by hand. The same applies to an appropriately designed fragrance addition capsule. Both fragrance addition solids are easy to handle because they are sufficiently large and therefore easy to handle. This applies in particular to the case where the fragrance addition tablets or capsules preferably contain more than 2.5 grams of fragrance and have a minimum volume of 5 cm 3. If fragrance addition tablets of this size prove to be too large or not suitable for direct addition to certain washing machine machines, the tablets could be provided with notch incisions which form predetermined breaking points and could thus be easily comminuted by hand before being put into the washing machine.

Es empfiehlt sich, jeweils mehrere Duftstoffzugabe-Ta­bletten oder -Kapseln voneinander getrennt in einer gemeinsa­men, die wasser- und gasdichte Umhüllungsschicht bildenden Verkaufspackung unterzubringen. Vorteilhaft sind die Duft­stoffzugabe-Tabletten oder -Kapseln dabei in entsprechend ge­stalteten Aufnahmevertiefungen einer damit versehenen Plastik-­ Durchdrücktafel untergebracht, die oberseitig mit einer die Aufnahmevertiefungen abdeckenden, zerstörbaren Aluminiumfolie versehen ist. Aus solchen Plastik-Durchdrücktafeln können die darin geschützt untergebrachten Tabletten oder Kapseln für den Bedarfsfall einzeln durch leichten Fingerdruck herausgedrückt werden.It is advisable to store several fragrance tablets or capsules separately from each other in a common sales package that forms the water and gas-tight wrapping layer. The fragrance addition tablets or capsules are advantageous in appropriately designed receiving recesses in a plastic container provided with them. Push-through board housed, which is provided on the top with a destructible aluminum foil covering the receiving recesses. The tablets or capsules, which are protected in them, can be individually pressed out of such plastic push-through boards by light finger pressure if necessary.

  • Fig. 5 and 6, a single fragrance capsule in top view and front view, while the
  • Fig. 7 and 8 show a sales package provided with fragrance capsules in top view and side view.

Das in Fig.1 und 2 dargestellte Duftstoffzugabemittel für Waschmaschinenautomaten besteht im wesentlichen aus dem in kreiszylindrischer Tablettenform vorliegenden festen Duft­stoffzugabekörper 1, der mindestens ein Gramm Duftstoff und im übrigen einen Füll- oder Trägerstoff enthält und in Wasser löslich oder dispergierbar ist, sowie der diese Tablette 1 allseits wasser- und gasdicht umschließenden Umhüllungsschicht 2, die beispielsweise aus einer Klarsichtfolie bzw. zwei sol­chen Folienhälften besteht, die in der gemeinsamen Äquatorial­ebene 3 miteinander verschweißt sind. Die Duftstoff enthalten­de Tablette 1 besitzt einen Rauminhalt von mehr als 1 cm³ im vorliegenden Fall von nahezu 7 cm³. Um sie notfalls leicht Zerkleinern zu können, ist sie mit Sollbruchstellen bildenden Kerbeinschnitten 4 versehen. Zur Ingebrauchnahme der Duft­stoffzugabetablette 1, also vor dem Ingangsetzen der automati­ schen Waschmaschine, kann die sie schützende Umhüllungsschicht 2 an der vorgesehenen Trennstelle 5 von Hand leicht aufgeris­sen und somit die Tablette 1 freigelegt werden. Sie wird so­dann in das entsprechende Wasch- bzw. Spülmittelvorratsfach des Waschautomaten gelegt, von wo aus sie gegen Ende des ent­sprechenden Waschprozesses, nämlich entweder während des letz­ten Waschganges oder aber während der abschließenden Spülphase in den Maschinentrommelraum bzw. die darin vorhandene Wasch- oder Spülflüssigkeit eingespült wird.The fragrance addition agent for automatic washing machines shown in FIGS. 1 and 2 essentially consists of the solid fragrance addition body 1, which is in the form of a circular cylindrical tablet, which contains at least one gram of fragrance and, moreover, a filler or carrier and is soluble or dispersible in water, and this tablet 1 enveloping layer 2, which encloses water and gas-tight on all sides, which consists, for example, of a transparent film or two such film halves which are welded to one another in the common equatorial plane 3. The fragrance-containing tablet 1 has a volume of more than 1 cm³ in the present case of almost 7 cm³. In order to be able to crush it easily if necessary, it is provided with notch incisions 4 which form predetermined breaking points. To put the fragrance tablet 1 into use, i.e. before starting the automati The washing machine protecting it can be torn open by hand at the intended separation point 5 and thus the tablet 1 can be exposed. It is then placed in the corresponding washing or rinsing agent storage compartment of the washing machine, from where it is washed into the machine drum space or the washing or rinsing liquid present therein towards the end of the corresponding washing process, namely either during the last washing cycle or during the final rinsing phase becomes.

Die Duftstoffzugabe-Tablette sollte tunlichst mehr als 2,5 Gramm Duftstoff enthalten und ein Mindestvolumen von 5 cm³ besitzen, weil sie dann besonders einfach zu handhaben ist und vor allem auch eine ausreichend hohe wirksame Duftstoffmenge in das Wasch- bzw. Spülwasser des Waschautomaten einzuschleu­sen erlaubt. Außer dem Duftstoff können die Tabletten 1 als Füll- bzw. Trägerstoff ein Natrium-Aluminium-Silikat (Sarsil), ein Cyclodextrin wie aber auch jeden anderen geeigneten Füll- bzw. Trägerstoff enthalten.The fragrance addition tablet should contain as much as possible more than 2.5 grams of fragrance and have a minimum volume of 5 cm³ because it is then particularly easy to handle and, above all, allows a sufficiently high effective amount of fragrance to be introduced into the washing or rinsing water of the washing machine . In addition to the fragrance, the tablets 1 can contain a sodium aluminum silicate (Sarsil), a cyclodextrin, as well as any other suitable filler or carrier, as the filler or carrier.

Für die Aufbewahrung und den Versand der Duftstoffzugabe-­Tabletten 1 empfiehlt sich die in Fig.3 und 4 dargestellte Verkaufspackung 6. Diese besteht aus der mit Aufnahmevertie­fungen 7 versehenen Plastik-Durchdrücktafel 8, die oberseitig mit einer die Aufnahmevertiefungen 7 und die darin unterzu­bringenden Duftstoffzugabetabletten 1 abdeckenden, zerstörba­ren Aluminiumfolie 9 versehen ist. Ebenso wie Arznei-Tabletten können auch die Duftstoffzugabe-Tabletten 1 in den Aufnahme­vertiefungen 7 der Durchdrücktafel 8 dauerhaft geschützt auf­bewahrt werden. Für den Fall der Ingebrauchnahme einer Tablet­te braucht dazu lediglich durch leichten Druck auf die Unter­seite der zugehörigen Aufnahmevertiefung 7 die Tablette 1 et­was nach oben gedrückt zu werden, wobei die Aluminiumfolie 9 an der entsprechenden Stelle aufreißt und die Tablette 1 ohne weiteres entnommen werden kann, ohne daß dadurch die übrigen Tabletten 1 in ihrer geschützten Unterbringungs- und Aufbewah­rungsart beeinträchtigt werden.For the storage and shipping of the fragrance addition tablets 1, the sales pack 6 shown in FIGS. 3 and 4 is recommended. This consists of the plastic push-through panel 8 provided with receiving recesses 7, the top side of which with a receiving recess 7 and the fragrance addition tablets 1 to be accommodated therein covering, destructible aluminum foil 9 is provided. Just like medicinal tablets, the fragrance addition tablets 1 can be kept permanently protected in the receiving recesses 7 of the push-through tablet 8. In the event that a tablet is put into use, the tablet 1 only needs to be pressed slightly upwards by light pressure on the underside of the associated receiving recess 7, the aluminum foil 9 tearing open at the corresponding point and the tablet 1 being able to be removed without further notice that this affects the remaining tablets 1 in their protected accommodation and storage.

Das in Fig.5 und 6 dargestellte Duftstoffzugabemittel ist als Kapsel 10 ausgebildet, in welcher sich der Duftstoff in flüssiger Form befindet und außerdem noch ein Emulgator ent­halten ist. Auch hier enthält die Kapsel 10 vorteilhaft mehr als 2,5 Gramm Duftstoff und besitzt ein Mindestvolumen von 5 cm³. Zu ihrer sicheren geschützten Aufbewahrung ist die ein­zelne Kapsel 10 wiederum mit einer wasser- und gasdichten Um­hüllungsschicht 2 umgeben. Diese kann wie im Falle der Fig.1 und 2 aus zwei in der Äquatorialebene 3 miteinander ver­schweißten Folienhälften bestehen und eine Aufreißlinie 5 be­sitzen. Das Gewichtsverhältnis zwischen dem in der Kapsel 10 enthaltende Emulgator einerseits und dem Duftstoff anderer­seits sollte zweckmäßig zwischen 1:1 und 4:1 betragen.5 and 6 is designed as a capsule 10, in which the fragrance is in liquid form and also contains an emulsifier. Here too, the capsule 10 advantageously contains more than 2.5 grams of fragrance and has a minimum volume of 5 cm 3. For their safe, protected storage, the individual capsule 10 is in turn surrounded by a water and gas-tight covering layer 2. As in the case of FIGS. 1 and 2, this can consist of two film halves welded together in the equatorial plane 3 and have a tear line 5. The weight ratio between the emulsifier contained in the capsule 10 on the one hand and the fragrance on the other hand should expediently be between 1: 1 and 4: 1.

Die Fig.7 und 8 stellen eine vorteilhaft beschaffene Ver­kaufspackung für die einzelnen Duftstoffzugabe-Kapseln 10 dar. Auch hier besteht die Verpackung im wesentlichen aus einer mit entsprechenden Aufnahmevertiefungen 7 für die Kapseln 10 ver­sehenen Plastik-Durchdrücktafel 8 und der sie oberseitig ab­deckenden, fest mit ihr verbundenen Aluminiumfolie 9. Auch hier können die Kapseln 10 einzeln bequem der Durchdrücktafel 8 entnommen werden, ohne daß die Nachbarkapseln 10 bzw. deren Aufnahmeräume dadurch in Mitleidenschaft geraten.FIGS. 7 and 8 represent an advantageous sales pack for the individual fragrance addition capsules 10. Here, too, the packaging essentially consists of a plastic push-through panel 8 provided with corresponding receiving recesses 7 for the capsules 10 and of the push-through panel 8 covering it firmly on top its associated aluminum foil 9. Here, too, the capsules 10 can be conveniently removed individually from the push-through plate 8 without the adjacent capsules 10 or their receiving spaces thereby being affected.
