Description

Die Erfindung bezieht sich auf einen Spender für ein aus zwei Bestandteilen zusammengestelltes flüssiges Medium.The invention relates to a dispenser for a liquid medium composed of two components.

Es gibt für die Aufnahme von flüssigen Medien für den täglichen Gebrauch, wie beispielsweise Spülmittel, Flüssigseifen, Parfums, Sonnenschutzmittel und dgl. Flaschen oder Dosen, die mit einem Aufsatz versehen sind, in dem eine manuell betätigbare Pumpe angeordnet ist, mit deren Hilfe der Behälterinhalt zu einer Spenderdüse gepumpt werden kann. Solche Behältnisse mit Pumpeinrichtungen sind allgemein bekannt.There are for the reception of liquid media for daily use, such as detergents, liquid soaps, perfumes, sunscreens and the like. Bottles or cans are provided with an attachment in which a manually operable pump is arranged, with the aid of which the contents of the container are arranged can be pumped to a dispenser nozzle. Such containers with pumping devices are generally known.

Aus der DE-OS 33 16 922 ist eine Vorrichtung zum Abgeben von in einem vorgegebenen Verhältnis zu mischenden flüssigen Stoffen bekannt, die ein Kolben-Zylinder-System aufweist, das eine der Anzahl der zu mischenden Stoffe entsprechende Zahl von nebeneinanderliegenden, je einen Ausstoßkolben enthaltenden Zylindern aufweist. Diese Zylinder sind selbst die Vorratsbehälter für die abzugebenden Stoffe, und ihr wirksames Volumen wird durch Vorschieben der Kolben mit zunehmenden Verbrauch der Stoffe vermindert. Alle Kolben werden gemeinsam von einem Spindelmechanismus bewegt, der an einem Handrad betätigbar ist.From DE-OS 33 16 922 a device for dispensing liquid substances to be mixed in a predetermined ratio is known, which has a piston-cylinder system which has a number corresponding to the number of substances to be mixed, of juxtaposed ones each containing an ejection piston Has cylinders. These cylinders are themselves the storage containers for the substances to be dispensed, and their effective volume is reduced by advancing the pistons with increasing consumption of the substances. All pistons are moved together by a spindle mechanism that can be operated on a handwheel.

Aus der EP-A-0 510 352 ist ein Spender für ein Haarfärbemittel bekannt, der in einem ersten Behälter, der ein Haarfärbemittel und ein Treibmittel aufnimmt, einen zweiten Behälter enthält, der einen Haarfärbeentwickler aufnimmt. Der Spender weist weiterhin eine Abgabedüse und eine Ventilkonstruktion mit ersten und zweiten Ventilen auf, die mit den beiden Behältern und der Abgabedüse verbunden sind und gleichzeitig betätigt werden, um ein gleichzeitiges Ausströmen der in den ersten und zweiten Behältern enthaltenen Flüssigkeiten unter dem Einfluß des Treibmittels zu ermöglichen, wobei das Mischungsverhältnis der Behälterinhalte an der Abgabedüse unveränderlich ist.From EP-A-0 510 352 a dispenser for a hair colorant is known which contains in a first container which contains a hair colorant and a blowing agent, a second container which receives a hair color developer. The dispenser further comprises a dispensing nozzle and a valve construction with first and second valves which are connected to the two containers and the dispensing nozzle and are actuated simultaneously to simultaneously allow the liquids contained in the first and second containers to flow out under the influence of the propellant enable, the mixing ratio of the container contents at the dispensing nozzle is unchangeable.

Es gibt Anwendungsfälle, in denen man das Mischungsverhältnis einer aus zwei Komponenten bestehenden Flüssigkeit nach persönlichem Wunsch einstellen und ggf. auch verändern möchte. Ein typisches Beispiel ist Sonnenschutzmittel. Die noch unbestrahlte Haut des Menschen ist gegen Sonnenbestrahlung empfindlicher, als schon gebräunte Haut. Setzt man sich erstmalig der Sonne aus, muß man für den Sonnenschutz einen höheren Lichtschutzfaktor wählen als erforderlich ist, wenn die Haut bereits mehr oder minder von der Sonne gebräunt ist. Um nun nicht ein ggf. umfangreiches Sortiment von Sonnenschutzmitteln unterschiedlicher Lichtschutzfaktoren mit sich führen zu müssen, besteht der Wunsch nach einem Sonnenschutzmittel, dessen Lichtschutzfaktor man nach Belieben einstellen kann. Da dieses in der Praxis nur durch Mischung zweier Sonnenschutzmittel unterschiedlich hoher Lichtschutzfaktoren erreicht werden kann, sollte ein Spender für ein flüssiges Medium entwickelt werden, der zwei flüssige Komponenten in frei wählbarem Mischungsverhältnis abgeben kann.There are applications in which you want to adjust the mixing ratio of a liquid consisting of two components according to your personal wishes and, if necessary, also change them. On a typical example is sunscreen. The still unexposed skin of humans is more sensitive to sun exposure than already tanned skin. If you are exposed to the sun for the first time, you have to choose a higher sun protection factor than necessary if the skin is already more or less tanned by the sun. In order not to have to carry a possibly extensive range of sunscreens with different sun protection factors, there is a desire for a sunscreen whose sun protection factor can be adjusted as desired. Since this can only be achieved in practice by mixing two sunscreens with different sun protection factors, a dispenser for a liquid medium should be developed that can dispense two liquid components in a freely selectable mixing ratio.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the invention specified in claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Im Rahmen der Erfindung sind zwei Konzepte denkbar, nämlich eines, bei dem die Auslässe zweier Aufnahmeabteile eines Behälters für unterschiedliche, flüssige Medien direkt mit einem Mischer verbunden sind, dessen Mischungsverhältnis einstellbar ist und dessen Ausgang ggf. über eine Pumpe mit einer Spenderdüse verbunden ist, und ein anderes, bei dem die Auslässe zweier Aufnahmeabteile mit je einer gesonderten Pumpe verbunden sind, deren Auslässe mit einem gemeinsamen Mischer verbunden und deren Fördervolumina gegenseitig verstellbar sind.Within the scope of the invention, two concepts are conceivable, namely one in which the outlets of two receiving compartments of a container for different liquid media are directly connected to a mixer, the mixing ratio of which is adjustable and the output of which is connected to a dispenser nozzle via a pump, if necessary, and another, in which the outlets of two receiving compartments are each connected to a separate pump, the outlets of which are connected to a common mixer and whose delivery volumes are mutually adjustable.

Der Vorteil des Konzepts mit zwei Pumpen besteht darin, daß nach einem Verändern des Mischverhältnisses das neu eingestellte Verhältnis auch relativ rasch tatsächlich an der Spenderdüse erhalten wird. Beim anderen Konzept ist erst nach einigen Pumpvorgängen möglich das neu eingestellte Verhältnis zu erreichen.The advantage of the concept with two pumps is that after changing the mixing ratio, the newly set ratio is actually obtained relatively quickly at the dispenser nozzle. With the other concept, it is only possible to achieve the newly set ratio after a few pumping processes.

Man erkennt in Fig. 1 einen insgesamt mit 1 bezeichneten Behälter, der im Innern in zwei Aufnahmeabteile 2 und 3 und in eine Kopfkammer 4 durch Wände 5 unterteilt ist. In der Kopfkammer 4 ist ein Mischventil 6 angeordnet, das zwei Einlässe 7 und 8 hat, an die Saugleitungen 9 und 10 als Auslaßeinrichtungen der Aufnahmeabteile 2 und 3 angeschlossen sind. Das Mischventil 6 hat einen Auslaß 11, an den eine Entnahmepumpe 12 angeschlossen ist, die mit einer Spenderdüse 13 versehen ist.1 shows a container, generally designated 1, which is divided into two interior compartments 2 and 3 and a head chamber 4 by walls 5. In the head chamber 4 a mixing valve 6 is arranged, which has two inlets 7 and 8, to which suction lines 9 and 10 are connected as outlet devices of the receiving compartments 2 and 3. The mixing valve 6 has an outlet 11, to which a withdrawal pump 12 is connected, which is provided with a dispensing nozzle 13.

Gemäß Fig. 1 und 2 weist das Mischventil 6 eine Mischkammer 14 auf, in die die Einlässe 7 und 8 münden. Es enthält ferner einen Einstellhebel 15, der mit einem in der Mischkammer 14 angeordneten Drehschieber 16 verbunden ist, mit dessen Hilfe die Öffnungsquerschnitte der Einlässe 7 und 8 in die Mischkammer 14 gegenseitig stufenlos verändert werden können.1 and 2, the mixing valve 6 has a mixing chamber 14 into which the inlets 7 and 8 open. It also contains an adjusting lever 15, which is connected to a rotary valve 16 arranged in the mixing chamber 14, by means of which the opening cross sections of the inlets 7 and 8 into the mixing chamber 14 can be mutually changed continuously.

Betätigt man die Entnahmepumpe 12 durch Drücken auf die Spenderdüse 13, wird in üblicher Weise, wie dies bei Parfumzerstäubern, Flüssigseifespendern und dgl. bekannt ist, wird Flüssigkeit aus dem Behälter 1 zur Spenderdüse 13 gepumpt. Auf den diesbezüglichen Mechanismus braucht hier nicht weiter eingegangen zu werden, da er allgemein bekannt ist. Das gegenseitige Mengenverhältnis der Flüssigkeiten, die aus den Aufnahmeabteilen 2 und 3 herausgepumpt werden, hängt dabei von der Stellung des Drehschiebers 15 in der Mischkammer 14 und im gewissen Umfang auch von der Viskosität der geförderten Flüssigkeiten ab, sofern sie bei den beiden Flüssigkeiten nicht gleich ist.If the extraction pump 12 is actuated by pressing on the dispenser nozzle 13, liquid is pumped from the container 1 to the dispenser nozzle 13 in a conventional manner, as is known in the case of perfume atomizers, liquid soap dispensers and the like. The mechanism in this regard does not need to be discussed further here since it is generally known. The mutual quantitative ratio of the liquids that are pumped out of the receiving compartments 2 and 3 depends on the position of the rotary valve 15 in the mixing chamber 14 and to a certain extent also on the viscosity of the liquids conveyed, unless it is the same for the two liquids .

Fig. 3 zeigt eine Ausführungsform der Erfindung mit einem Behälter 1, der in zwei Aufnahmeabteile 2 und 3 und eine Kopfkammer 4 unterteilt ist. In der Kopfkammer 4 befinden sich zwei Pumpen 17 und 18, deren Einlässe 7 und 8 mit Saugleitungen 9 und 10 verbunden sind, die in die Aufnahmeabteile 2 und 3 hinabreichen. Die Pumpen 17 und 18 weisen Kolben auf, deren Kolbenstangen 19 und 20 mit einem gemeinsamen Pumphebel 21 an unterschiedlichen Stellen a und b verbunden sind, die von einem Schwenklager 22 des Hebels 21 unterschiedliche Abstände haben.Fig. 3 shows an embodiment of the invention with a container 1, which is divided into two receiving compartments 2 and 3 and a head chamber 4. In the head chamber 4 there are two pumps 17 and 18, the inlets 7 and 8 of which are connected to suction lines 9 and 10 which extend down into the receiving compartments 2 and 3. The pumps 17 and 18 have pistons, the piston rods 19 and 20 of which are connected to a common pump lever 21 at different points a and b, which are at different distances from a pivot bearing 22 of the lever 21.

Die Auslässe der Pumpen 17 und 18 sind mit einem gemeinsamen Mischrohr 23 verbunden, das zu einer Spenderdüse 13 führt.The outlets of the pumps 17 and 18 are connected to a common mixing tube 23 which leads to a dispenser nozzle 13.

Gemäß Fig. 3 ist der Ort des Schwenklagers 22 des Pumphebels 21 nach links und rechts verstellbar. Dieses ist in Fig. 3 durch den Pfeil 24 angedeutet. Da die Fördervolumina der Pumpen 17 und 18 bei gegebenem Schwenkwinkel des Pumphebels 21 von den Abständen der Angriffspunkte a und b zum Schwenklager 22 bestimmt sind, kann durch Verstellung des Schwenklagers 22 gemäß Pfeil 24 das Verhältnis der pro Pumphebelhub geförderten Volumina der Pumpen 17 und 18 und somit das Mengenverhältnis der abgegebenen Komponenten aus den Aufnahmeabteilen 2 und 3 verändert werden. Es versteht sich, daß der Verstellmechanismus für das Schwenklager 22 von außen zugänglich ist, beispielsweise als Drehknopf eines Spindeltriebs.3, the location of the pivot bearing 22 of the pump lever 21 is adjustable to the left and right. This is indicated in Fig. 3 by the arrow 24. Since the delivery volumes of the pumps 17 and 18 are determined at a given pivoting angle of the pump lever 21 from the distances of the points of application a and b to the pivot bearing 22, the ratio of those pumped per pump lever stroke can be adjusted by adjusting the pivot bearing 22 according to arrow 24 Volumes of the pumps 17 and 18 and thus the quantitative ratio of the components delivered from the receiving compartments 2 and 3 can be changed. It is understood that the adjustment mechanism for the pivot bearing 22 is accessible from the outside, for example as a rotary knob of a spindle drive.

Es sei abschließend erwähnt, daß die Aufnahmeabteile zweckmäßigerweise nachfüllbar sein sollten um den Spender möglichst wirtschaftlich einsetzen zu können.It should finally be mentioned that the receiving compartments should expediently be refillable in order to be able to use the dispenser as economically as possible.

Fig. 4 zeigt eine Ausführungsform mit einer Tube als Behälter 1, deren Innenraum durch eine Membran 5 in zwei Kammern 2 und 3 unterteilt ist. Die Tube ist an ihrem oberen Ende von einem Kopf 4 kreisförmigen Umrisses abgeschlossen. Die Kammern 2 und 3 weisen an ihren oberen Enden Auslässe 9 und 10 aus, die bezüglich der Achse des Tubenkopfes 4 einander diametral gegenüberliegen, und diese münden in den Tubenkopf 4, in dem ein Drehkörper 16 um die Achse des Tubenkopfes 4 drehbar gehalten ist. Der Drehkörper 16 weist an seiner den Auslässen 9 und 10 zugewandten Unterseite eine kreisförmige, exzentrisch angeordnete Vertiefung auf, die eine über den Auslässen 9 und 10 gelegene Mischkammer 14 ausbildet. Der Drehkörper hat eine zentrische Spenderdüse 13, die mit der Mischkammer 14 in Verbindung ist.Fig. 4 shows an embodiment with a tube as a container 1, the interior of which is divided into two chambers 2 and 3 by a membrane 5. The tube is closed at its upper end by a head 4 circular outline. The chambers 2 and 3 have at their upper ends outlets 9 and 10, which are diametrically opposite to each other with respect to the axis of the tube head 4, and these open into the tube head 4, in which a rotating body 16 is held rotatably about the axis of the tube head 4. The rotating body 16 has on its underside facing the outlets 9 and 10 a circular, eccentrically arranged depression which forms a mixing chamber 14 located above the outlets 9 and 10. The rotating body has a central dispensing nozzle 13 which is connected to the mixing chamber 14.

Aufgrund der exzentrischen Anordnung der die Mischkammer 14 ausbildenden Vertiefung werden je nach Drehstellung des Drehkörpers die Auslässe 9 und 10 von der unteren Stirnfläche des Drehkörpers unterschiedlich groß verschlossen. Durch Verdrehen des Drehkörpers 16 läßt sich somit das Verhältnis der freien Querschnittsflächen der Auslässe 9 und 10 verändern und somit der gegenseitige Mengenanteil der beim Drücken auf die Tube aus den Tubenkammern 2 und 3 ausströmenden Inhaltsanteile verändern.Because of the eccentric arrangement of the depression forming the mixing chamber 14, the outlets 9 and 10 are closed to different sizes by the lower end face of the rotating body, depending on the rotational position of the rotating body. By rotating the rotating body 16, the ratio of the free cross-sectional areas of the outlets 9 and 10 can thus be changed, and thus the mutual proportion of the contents that flow out of the tube chambers 2 and 3 when the tube is pressed.

Es sei betont, daß die Erfindung auch mit einem Behälter realisierbar ist, in dem zwei ausdrückbare Innenbeutel oder ein mit Membranwand unterteilter ausdrückbarer Innenbeutel vorhanden ist, der mittels eines im Behälter geführten, von außen betätigbaren Stempels zusammendrückbar ist. Als Misch- und Auslaßeinrichtung ist hierbei an die in Fig. 1 oben oder in Fig. 4 oben gezeigte Einrichtung einzusetzen.It should be emphasized that the invention can also be implemented with a container in which two inner bags which can be expressed or one with a membrane wall divided expressible inner bag is present, which can be compressed by means of a stamp guided in the container and actuated from the outside. The mixing and outlet device used here is the device shown at the top in FIG. 1 or at the top in FIG. 4.

Eine weitere Möglichkeit besteht darin, den Flüssigkeiten in den Aufnahmeabteilen 2, 3 ein Treibmittel beizugeben, das die Funktion des Austreibens der Flüssigkeiten übernimmt. In diesem Fall entfällt die Notwendigkeit des Vorsehens einer Pumpe.Another possibility is to add a propellant to the liquids in the receiving compartments 2, 3, which takes over the function of expelling the liquids. In this case there is no need to provide a pump.

Fig. 5 und 6 zeigen eine weitere Ausführungsform des erfindungsgemäßen Spenders mit zwei Pumpen. Diejenigen Teile dieser Ausführungsform, die mit denjenigen der vorangehend beschriebenen Ausführungsformen übereinstimmen, sind mit gleichen Bezugszeichen gekennzeichnet und werden daher nicht nochmals detailliert beschrieben.5 and 6 show a further embodiment of the dispenser according to the invention with two pumps. Those parts of this embodiment which correspond to those of the previously described embodiments are identified by the same reference numerals and are therefore not described in detail again.

Der wesentliche Unterschied der Ausführungsform der Fig. 5 und 6 gegenüber derjenigen der Fig. 3 besteht in der anders ausgeführten Einstelleinrichtung.The essential difference of the embodiment of FIGS. 5 and 6 compared to that of FIG. 3 lies in the differently configured setting device.

Die Einstelleinrichtung besteht hier aus einem für den Bediener von außen betätigbaren Betätigungselement 24 zum Einstellen des Mengenverhältnisses der Flüssigkeiten. Das Betätigungselement 24 ist in einer entsprechend geformten Öffnung im Behälter 1 drehbar gelagert. Auf der dem Behälterinneren zugewandten Seite des Betätigungselements steht ein Lagerzapfen 25 hervor, der in einem Längsschlitz eines Koppelelements 26 geführt ist (vergleiche Darstellung links oben in Fig. 5). Das Koppelelement ist mit beiden Pumpen 17, 18 verbunden und wird beim Verdrehen des Betätigungselements zusammen mit den Pumpen 17, 18 verschwenkt (Fig. 6). Die oberen Enden der Pumpen 17, 18 weisen Lagerrollen 27, 28 auf, die in Führungsschienen 29, 30 geführt sind. Dies ermöglicht ein Verschwenken der Pumpen entlang eines kreisliniensektorförmigen Weges. Die Führungsschienen 29, 30 besitzen jeweils ein in der Nähe der Außenwand des Behälters 1 befindliches Schwenklager 31. Dadurch wirken die Führungsschienen 29, 30 gleichzeitig als Hebelarme, um einen Druck, der auf die Spenderdüse 13 senkrecht nach unten ausgeübt wird, auf die Kolbenstangen der Pumpen 17, 18 zu übertragen.The setting device here consists of an actuating element 24 which can be actuated from the outside for the operator to set the quantitative ratio of the liquids. The actuating element 24 is rotatably mounted in a correspondingly shaped opening in the container 1. On the side of the actuating element facing the inside of the container, a bearing journal 25 protrudes, which is guided in a longitudinal slot of a coupling element 26 (cf. illustration at the top left in FIG. 5). The coupling element is connected to both pumps 17, 18 and is pivoted together with the pumps 17, 18 when the actuating element is rotated (FIG. 6). The upper ends of the pumps 17, 18 have bearing rollers 27, 28 which are guided in guide rails 29, 30. This enables the pumps to be pivoted along a circular sector-shaped path. The guide rails 29, 30 each have a near the Pivot bearing 31 located on the outer wall of the container 1. As a result, the guide rails 29, 30 simultaneously act as lever arms in order to transmit a pressure which is exerted vertically downward on the dispenser nozzle 13 to the piston rods of the pumps 17, 18.

Wenn sich der Lagerzapfen in der in Fig. 5 gezeigten Stellung befindet, ist der Hub der beiden Pumpen 17, 18 gleich groß. Demgegenüber ist bei der in Fig. 6 gezeigten Stellung des Lagerzapfens 25 der Hub der Pumpe 18 maximal und derjenige der Pumpe 17 minimal. Der Fachmann erkennt, daß dadurch das Mengenverhältnis der zu fördernden Flüssigkeiten stufenlos einstellbar ist. Die Auslaßöffnungen der Pumpen 17, 18 sind über flexible Schlauchleitungen mit der Spenderdüse 13 verbunden, wie dies der Darstellung des Spenders von vorne in Fig. 5 entnehmbar ist. Der Übersichtlichkeit halber sind die Schlauchleitungen in Fig. 6 nicht eingezeichnet. Die Spenderdüse 13 enthält ein Mischrohr, so wie dies in der Ausführungsform der Fig. 3 gezeigt ist.When the journal is in the position shown in FIG. 5, the stroke of the two pumps 17, 18 is the same. In contrast, in the position of the bearing pin 25 shown in FIG. 6, the stroke of the pump 18 is maximum and that of the pump 17 is minimal. The person skilled in the art recognizes that the quantity ratio of the liquids to be conveyed can be adjusted continuously. The outlet openings of the pumps 17, 18 are connected to the dispenser nozzle 13 via flexible hose lines, as can be seen from the front of the dispenser in FIG. 5. For the sake of clarity, the hose lines are not shown in FIG. 6. The dispensing nozzle 13 contains a mixing tube, as shown in the embodiment of FIG. 3.

Weiterhin ist bei der Ausführungsform der Fig. 5 und 6 hervorzuheben, daß der Boden der Aufnahmeabteile "mitwandert", um das Fördern von Luftblasen, insbesondere bei nicht senkrechter Lage des Spenders, zu verhindern.Furthermore, it should be emphasized in the embodiment of FIGS. 5 and 6 that the bottom of the receiving compartments "migrates" in order to prevent the conveyance of air bubbles, in particular when the dispenser is not in a vertical position.

Demgegenüber zeigt die Variante des Spenders gemäß Fig. 7 eine Ausführungsform mit zwei Saugleitungen 9, 10, ähnlich der Ausführungsform der Fig. 3.In contrast, the variant of the dispenser according to FIG. 7 shows an embodiment with two suction lines 9, 10, similar to the embodiment of FIG. 3.
