Description

Die Erfindung bezieht sich auf einen Spender für ein aus zwei Komponenten zusammengestelltes flüssiges Medium, nach dem Oberbegriff des Patentanspruchs 1, bzw. 3. Ein Spender dieser Art ist aus der EP-A-0 026 902 bekannt.The invention relates to a dispenser for one out of two Components composed liquid medium, after which Preamble of claim 1 or 3. A donor of this type known from EP-A-0 026 902.

Der vorbekannte Spender besteht aus einem Flüssigkeits-Vorratsbehälter, der an eine Sprühpumpe angekoppelt ist. Der Vorratsbehälter enthält eine Mischkammer, mit der die Einzelkammern über je ein Steigrohr mit Rückschlagventil verbunden sind. Die Querschnitte der mischkammerseitigen Steigrohrausgänge sind mit Hilfe eines von außerhalb betätigenden Reguliermittels zur Steuerung des Komponenten-Mischungsverhältnisses einstellbar. Die Sprühpumpe entnimmt die abzugebende gemischte Flüssigkeit der Mischkammer.The known dispenser consists of a liquid storage container, which is coupled to a spray pump. Of the Storage container contains a mixing chamber with which the Individual chambers each with a riser pipe with a check valve are connected. The cross sections of the mixing chamber side Riser pipe exits are with the help of an outside actuating regulating means for controlling the component mixing ratio adjustable. The spray pump takes the mixed liquid to be dispensed from the mixing chamber.

Aus der US-A-3 760 986 ist ein Flüssigkeitsspender bekannt, der einen in zwei Abteile unterteilten Vorratsbehälter und einen darauf aufgesetzten Pumpkopf aufweist. Der Pumpkopf enthält zwei nebeneinander angeordnete Pumpen, die über Saugleitungen mit Rückschlagventil mit den Behälterabteilen verbunden sind und aufgrund ihrer starren Verbindung simultan betätigt werden. Eine Einstellung des Mengenverhältnisses der von den Pumpen abgegebenen Flüssigkeiten ist nicht möglich. From US-A-3 760 986 a liquid dispenser is known which a storage container divided into two compartments and one has pump head placed thereon. The pump head contains two pumps arranged side by side, via suction lines are connected to the container compartments with a check valve and operated simultaneously due to their rigid connection. A setting of the quantity ratio of the pumps dispensed liquids are not possible.

Aus der EP-A-0 520 315 ist ein Dosierpumpenspender für flüssige und/oder pastöse Medien bekannt, der zur gleichzeitigen dosierten Ausgabe aus wenigstens zwei separaten Vorratskammern, die in einem gemeinsamen pumpengehäuse angeordnet sind, dient. Den Vorratskammern sind einzeln separate Dosierpumpen mit je einem Ansaug- und Ausgabeventil zugeordnet, die von einem gemeinsamen Betätigungsorgan manuell betätigbar sind, das sich betätigungsseitig in einer gemeinsamen Stirnseite der Dosierpumpen erstreckt. Die Dosierpumpen weisen als Pumporgane jeweils Faltenbälge auf, die mit dem gemeinsamen Betätigungsorgan verbunden sind. Letzteres ist hebelartig in einem die Vorratskammern axial überragenden Kopfteil des pumpengehäuses um ein Schwenklager einseitig schwenkbar gelagert. Die Schwenkachse des Schwenklagers kann bei der Montage des Dosierpumpenspenders auf eine von mehreren vorgegebenen, diskreten Stellungen eingestellt werden, um unterschiedlich große Betätigungshebel an den Dosierpumpen und dadurch unterschiedlich große pumphubverhältnisse einzustellen. Die Ausgänge der Dosierpumpen sind getrennt aus dem Dosierpumpenspender herausgeführt, eine Durchmischung der beiden Medien innerhalb des Dosierpumpenspenders findet somit nicht statt.EP-A-0 520 315 discloses a metering pump dispenser for liquid and / or pasty media known for simultaneous dosed output from at least two separate pantries, which are arranged in a common pump housing. The storage chambers are individually separate metering pumps with each a suction and discharge valve assigned by a common actuator are manually operable, the on the actuating side in a common end face of the Dosing pumps extends. The dosing pumps have pump organs each bellows on that with the common Actuator are connected. The latter is like a lever a axially projecting head of the pantry pump housing can be swiveled on one side around a swivel bearing stored. The pivot axis of the pivot bearing can be Installation of the dosing pump dispenser on one of several predetermined, discrete positions can be set to actuating levers of different sizes on the metering pumps and thereby setting different pump stroke ratios. The outputs of the metering pumps are separated from the Dosing pump dispenser led out, a mixing of the Both media within the dosing pump dispenser thus take place not instead.

Eis gibt Awendungsfälle, 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 die 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 Sonne gebräunt ist. Um nun nicht ein ggf. umfangreiches Sortiment von Sonnenschutzmitteln unterschiedlicher Lichtschutzfaktoren mitführen zu müssen, besteht der Wunsch nach einem Sonnenschutzmittel, dessen Lichtschutzfaktor man nach Belieben einstellen kann. Dieses kann man in der Praxis durch Mischung zweier Sonnenschutzmittel unterschiedlich hoher Lichtschutzfaktoren erreichen.Ice cream are use cases in which you have the mixing ratio a liquid consisting of two components want to set personal wish and change it if necessary. A typical example is sunscreen. The still unexposed human skin is against sun exposure more sensitive than the already tanned skin. If you sit down for the first time out of the sun, you need one for sun protection Choose a higher sun protection factor than is required if the Skin is already more or less tanned by the sun. Um now not a possibly extensive assortment of sunscreens having to carry different light protection factors, there is a desire for a sunscreen whose Sun protection factor can be adjusted at will. This can be done in practice by mixing two sunscreens achieve different levels of sun protection factors.

Aus der EP-A-0 427 609 ist ein dem Vorerwähnten ähnlicher Dosierpumpenspender für flüssige und/oder pastöse Medien bekannt, der zwei vorratsbehälter aufweist, die am Kopf mit Pumpen versehen sind. Die Anordnung wird von einer gemeinsamen Haube abgedeckt in der zwei Kanäle ausgebildet sind, die zwei benachbart am Rand der Haube ausgebildete Öffnungen mit den Pumpenausgängen verbinden. Über einer der Pumpen befindet sich eine drehbare Einstellscheibe, die an ihrer Unterseite mehrere unterschiedlich weit nach unten vorstehende Vorsprünge aufweist. Durch Verdrehen der Einstellscheibe kann ein Leerlauf eingestellt werden, der beim Drücken der Haube erst überwunden werden muß, bevor auf die betreffende Pumpe ein Bewegungshub ausgeübt wird. Auf diese Weise ist eine Verstellung des Mischungsverhältnisses möglich, allerdings nur in wenigen fest vorgegebenen Stufen, was dem oben erläuterten Bedürfnis nicht in ausreichendem Maße gerecht wird.From EP-A-0 427 609 a similar one is mentioned Dosing pump dispenser for liquid and / or pasty media known, which has two storage containers, the head with Pumps are provided. The arrangement is of a common Hood covered in which two channels are formed, the two openings formed adjacent to the edge of the hood with the Connect pump outputs. Is located above one of the pumps a rotating shim that has several on its underside protrusions projecting downward to different degrees having. Turning the shim can idle can be set, which is only overcome when the hood is pressed must be before a movement stroke on the pump in question is exercised. This is an adjustment of the Mixing ratio possible, but only in a few fixed predetermined levels, which does not meet the need explained above is sufficient.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Spender der eingangs genannten Art anzugeben, der ein Gemisch aus zwei in frei wählbarem MischungsverhältniS zusammengestellte flüssige Komponenten abgeben kann.The invention is therefore based on the object of a donor of the type mentioned above, which is a mixture of two in a freely selectable mixing ratio can give off liquid components.

Diese Aufgabe wird durch die im Patentanspruch 1 und 3 angegebene Erfindung gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. This object is achieved by that specified in claims 1 and 3 Invention solved. Advantageous embodiments of the invention are the subject of the subclaims.

Fig. 1 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. 1 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 is divided. There are two in the head chamber 4 Pumps 17 and 18, the inlets 7 and 8 of which have suction lines 9 and 10 connected down into the receiving compartments 2 and 3. The pumps 17 and 18 have pistons, the piston rods 19 and 20 with a common pump lever 21 different points a and b are connected by one Pivot bearing 22 of the lever 21 have different distances.

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 in common Mixing tube 23 connected, which leads to a dispenser nozzle 13.

Gemäß Fig. 1 ist der Ort des Schwenklagers 22 des Pumphebels 21 nach links und rechts verstellbar. Dieses ist in Fig. 1 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 gemaß 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.1 is the location of the pivot bearing 22 of the pump lever 21 adjustable to the left and right. This is in Fig. 1 by indicated the arrow 24. Since the delivery volumes of the pumps 17th and 18 for a given pivot angle of the pump lever 21 from the Distances of the points of attack a and b to the pivot bearing 22 are determined can by adjusting the pivot bearing 22nd according to arrow 24 the ratio of the pumped per pump lever stroke Volumes of the pumps 17 and 18 and thus the ratio the delivered components from the receiving compartments 2 and 3 to 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 erwähnt, daß die Aufnahmeabteile zweckmäßigerweise nachfüllbar sein sollten um den Spender möglichst wirtschaftlich einsetzen zu können. It should be noted that the receiving compartments are convenient should be refillable to the donor if possible to be able to use it economically.

Fig. 2 und 3 zeigen eine zweite Ausführungsform des erfindungsgemäßen Spenders mit zwei Pumpen. Diejenigen Teile dieser Ausführungsform, die mit denjenigen der vorangehend beschriebenen Ausführungsform übereinstimmen, sind mit gleichen Bezugszeichen gekennzeichnet und werden daher nicht nochmals detailliert beschrieben.2 and 3 show a second embodiment of the dispenser according to the invention with two pumps. Those parts this embodiment, that with those of the previous described embodiment match, are with same reference numerals and are therefore not described again in detail.

Der wesentliche Unterschied der Ausführungsform der Fig. 2 und 3 gegenüber derjenigen der Fig. 1 besteht in der anders ausgeführten Einstelleinrichtung.The main difference of the embodiment of FIGS. 2 and 3 compared to that of FIG. 1 is different executed adjustment device.

Die Einstelleinrichtung besteht hier aus einem für den Bediener von außen einstellbaren 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. 2). Das Koppelelement ist mit beiden Pumpen 17, 18 verbunden und wird beim Verdrehen des Betätigungselements zusammen mit den Pumpen 17, 18 verschwenkt (Fig. 3). 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 consists of one for the operator externally adjustable actuator 24 for adjusting the Quantity ratio of the liquids. The actuator 24 is in a correspondingly shaped opening in the container 1 rotatably mounted. On the side facing the inside of the container the actuator protrudes a journal 25 which in a longitudinal slot of a coupling element 26 is guided (Compare illustration at the top left in Fig. 2). The Coupling element is connected to both pumps 17, 18 and is when turning the actuator together with the pumps 17, 18 pivoted (Fig. 3). The upper ends of the pumps 17, 18 have bearing rollers 27, 28 which in guide rails 29, 30th are led. This enables the pumps to pivot 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 the guide rails 29, 30 simultaneously act as lever arms, to a pressure that is perpendicular to the dispenser nozzle 13 downwards is exerted on the piston rods of the pumps 17, 18 transfer.

Wenn sich der Lagerzapfen in der in Fig. 2 gezeigten Stellung befindet, ist der Hub der beiden Pumpen 17, 18 gleich groß. Demgegenüber ist bei der in Fig. 3 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. 2 entnehmbar ist. Der Übersichtlichkeit halber sind die Schlauchleitungen in Fig. 3 nicht eingezeichnet. Die Spenderdüse 13 enthält ein Mischrohr, so wie dies in der Ausführungsform der Fig. 1 gezeigt ist.When the trunnion is in the position shown in Fig. 2 is located, the stroke of the two pumps 17, 18 is the same size. In contrast, in the position shown in Fig. 3 Bearing pin 25, the stroke of the pump 18 maximum and that of Pump 17 minimal. The skilled worker realizes that this will Quantity ratio of the liquids to be pumped continuously is adjustable. The outlet openings of the pumps 17, 18 are via flexible hose lines with the dispenser nozzle 13 connected, as is the representation of the donor from the front in Fig. 2 can be removed. For the sake of clarity, they are Hose lines not shown in Fig. 3. The Dispenser nozzle 13 contains a mixing tube, as in the Embodiment of Fig. 1 is shown.

Weiterhin ist bei der Ausführungsform der Fig. 2 und 3 hervorzuheben, daß der Boden der Aufnahmeabteile "mitwandert", um das Fördern von Luftblasen, insbesondere bei nicht senkrechter Lage des Spenders, zu verhindern.Furthermore, in the embodiment of FIGS. 2 and 3 to emphasize that the bottom of the receiving compartments "moves", to convey air bubbles, especially when not vertical position of the donor.

Demgegenüber zeigt die Variante des Spenders gemäß Fig. 4 eine Ausführungsform mit zwei Saugleitungen 9, 10, ähnlich der Ausführungsform der Fig. 1.In contrast, the variant of the dispenser according to FIG. 4 shows one Embodiment with two suction lines 9, 10, similar to that Embodiment of Fig. 1st
