Description

Die Erfindung betrifft einen Dosierspender gemäss dem Oberbegriff des Anspruches 1. Ein derartiger Dosierspender ist aus der EP 0 753 353 A2 bzw. FR 27 28 809 A1 bekannt.The invention relates to a metering dispenser according to the preamble of claim 1. Such a dispenser is from the EP 0 753 353 A2 respectively. FR 27 28 809 A1 known.

Aus dem Stand der Technik sind zudem Dosierspender bekannt, bei denen das Mischungsverhältnis zweier Komponenten stufenlos einstellbar ist. Ein derartiger Dosierspender lässt sich beispielsweise als Lippenproduktspender einsetzen, um zwei Komponenten mit unterschiedlichen Farbtönungen zu mischen, so dass sich die Farbe in einem breiten Bereich stufenlos einstellen lässt. Die Abmaße von Dosierspender für diese Produkte sind äußerst klein, daher benötigen diese einen sehr kompakten Aufbau aller Komponenten, insbesondere der Pumpeneinheit. Auch die Dosiermenge ist bei diesen Produkten im Vergleich zum Stand der Technik extrem klein. Zudem sind diese Produkte hoch viskos und benötigen somit eine Pumpe mit kleinem Totvolumen und relativ zum Dosiervolumen weit öffnende Ventile. Um bei diesen Anforderungen eine genaue Dosierung zu erreichen, sollten zusätzlich die Ventile exakt und selbsttätig schließen, um Produktrückfluss zu vermeiden. Des Weiteren muss eine kostengünstige Produktion durch Verwendung weniger Einzelteile und eine einfache Montage ermöglicht werden.Dosing dispensers are also known from the prior art, in which the mixing ratio of two components is infinitely adjustable. Such a dispenser can be used, for example, as a lip product dispenser to mix two components with different shades, so that the color can be adjusted continuously in a wide range. The dimensions of dispensers for these products are extremely small, so they require a very compact design of all components, especially the pump unit. The dosage amount is extremely small in these products compared to the prior art. In addition, these products are highly viscous and thus require a pump with a small dead volume and relative to the dosing volume wide-opening valves. In order to achieve an exact dosage for these requirements, the valves should also close exactly and automatically, in order to avoid product backflow. Furthermore, low-cost production must be enabled by using fewer parts and easy assembly.

Bei der WO 00/09270 , insbes. Fig. 3, besitzt der Dosierspender zwei Pumpeinheiten, denen jeweils eine auswechselbare Kartusche zugeordnet ist, in der beispielsweise jeweils ein Sonnenmilchtyp mit stark unterschiedlichen Lichtschutzfaktoren enthalten ist. Dies gilt auch für die Lösung gemäss der WO 03/092905 , bei der zwei Pumpeinheiten an der oberen Seite von je einer Kartusche vertieft eingesetzt sind und zudem durch zylindrische Vertiefungen im Gehäuse gehalten werden. Die Pumpeinheiten bzw. deren Pumpkolben werden dabei über ein Stellelement betätigt, das in Verbindung mit einem Pump- oder Düsenkopf steht, der in einem Gehäuse des Dosierspenders gelagert ist und vom Verbraucher über eine Handhabe betätigt wird. Diese bekannten Dosierspender haben sich in der Praxis grundsätzlich bewährt; gleichwohl haften ihnen noch Nachteile an. Insbesondere weisen die Pumpeinheiten und ihre Lagerung am Kartuschenausgang einen vergleichsweise komplizierten Aufbau auf.In the WO 00/09270 , esp. Fig. 3 , The dosing dispenser has two pumping units, each associated with a replaceable cartridge, in which, for example, each one suntan type is included with very different sun protection factors. This also applies to the solution according to the WO 03/092905 , in which two pump units are recessed on the upper side of each cartridge and also held by cylindrical recesses in the housing. The pump units or their pumping pistons are actuated via an actuating element which is in connection with a pump or nozzle head, which is mounted in a housing of the dosing dispenser and is actuated by the consumer via a handle. These known dosing dispensers have basically proven themselves in practice; however, they still suffer from disadvantages. In particular, the pumping units and their storage at the cartridge outlet have a comparatively complicated construction.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen Dosierspender zu schaffen, der wenigstens eine konstruktiv einfachere und betriebssichere Pumpeinheit aufweist.In contrast, the invention has for its object to provide a dosing dispenser having at least one structurally simpler and more reliable pump unit.

Diese Aufgabe wird durch einen Dosierspender mit den Merkmalen des Anspruches 1 gelöst. Bevorzugte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by a metering dispenser with the features of claim 1. Preferred embodiments are the subject of the dependent claims.

Die erfindungsgemäße Lösung hat im Vergleich zu den eingangs beschriebenen Dosierspendern einen besonders einfachen und stabilen Aufbau, da die Pumpeinheit im oberen Bereich der Kartusche bzw. des Behälters in einer Hülse geführt ist. Durch diese Hülse in Fortsetzung der Kartusche kann die jeweils zu dosierende Komponente einfach durch das Einlass- und Auslassventil der Pumpeinheit geleitet werden. Zudem kann durch diese Anordnung die Führung des Pumpkolbens bzw. die Lagerung des Pumpzylinders sehr stabil ausgeführt und die Anzahl der beweglichen Bauelemente reduziert werden. Bevorzugt ist die Pumpeinheit dabei als Spritzgussteil hergestellt.The solution according to the invention has a particularly simple and stable construction in comparison to the dispensers described above, since the pump unit is guided in the upper region of the cartridge or of the container in a sleeve. Through this sleeve in continuation of the cartridge, each component to be metered can be easily passed through the inlet and outlet valve of the pump unit. In addition, by this arrangement, the leadership of the pump piston or the storage of the pump cylinder can be made very stable and the number of movable components can be reduced. Preferably, the pump unit is made as an injection molded part.

Besonders vorteilhaft ist dabei, dass der Pumpkolben bzw. Pumpzylinder der jeweiligen Pumpeinheit mit der Hülse am Behälter besonders einfach montiert werden und dabei eine stabile Bauweise mit geringer Bauhöhe bietet. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der weiteren Unteransprüche. So ist die Hülse bevorzugt einstückig an dem Behälter angeformt, insbesondere in Spritzgusstechnik. Zudem kann die Hülse in ihrem Inneren Ring-Sicken oder Hinterschnitte zur Verrastung mit dem Pumpzylinder und/oder dem Pumpkolben aufweisen. Damit ist der Pumpzylinder in die Hülse sicher verankert bzw. eingepresst, so dass der Pumpzylinder mit seiner Unterseite ein Einlassventil, insbesondere in Form einer Membran sicher fixieren bzw. einklemmen kann.It is particularly advantageous that the pump piston or pump cylinder of the respective pump unit with the sleeve on the container are particularly easy to assemble and offers a stable design with low overall height. Advantageous developments of the invention are the subject of the other dependent claims. Thus, the sleeve is preferably integrally formed on the container, in particular in injection molding. In addition, the sleeve may have in its interior ring beads or undercuts for locking with the pump cylinder and / or the pump piston. Thus, the pump cylinder is securely anchored or pressed into the sleeve, so that the pump cylinder with its bottom an inlet valve, especially in the form of a membrane can securely fix or pinch.

Von besonderer Bedeutung ist die Ausführung der Feder für das Auslassventil, die an einem umklappbaren Federbügel angeordnet ist, wobei dieser bevorzugt mit dem Pumpkolben einstückig spritzgegossen ist. Dabei kann der Federbügel ein Filmscharnier und diesem gegenüberliegend einen Rastzapfen aufweisen, so dass sich eine einfache, kostengünstige Herstellung und Montage ergibt. Hierbei kann die Feder auch aus Kunststoff bestehen und einstückig in Mäanderform am Federbügel angeformt sein, so dass ein besonders einfacher Aufbau erzielt wird.Of particular importance is the design of the spring for the outlet valve, which is arranged on a folding spring clip, which is preferably injection-molded integrally with the pump piston. In this case, the spring clip a film hinge and this opposite have a locking pin, so that there is a simple, inexpensive production and assembly. Here, the spring may also be made of plastic and integrally formed in a meandering shape on the spring clip, so that a particularly simple structure is achieved.

Nachfolgend werden bevorzugte Ausführungsbeispiele der Erfindung anhand der Zeichnung näher erläutert. Hierbei zeigen:

  • Fig. 1 einen Behälter für eines Dosierspenders mit Pumpeinheit (in drei Ansichten);
  • Fig. 2 eine Ausführungsform eines Pumpkolbens (in drei Ansichten); und
  • Fig. 3 eine Detailansicht des Pumpzylinders in zwei Perspektivansichten.
Hereinafter, preferred embodiments of the invention will be explained in more detail with reference to the drawing. Hereby show:
  • Fig. 1 a container for a dispenser with pumping unit (in three views);
  • Fig. 2 an embodiment of a pump piston (in three views); and
  • Fig. 3 a detailed view of the pump cylinder in two perspective views.

Anhand der Perspektivansicht in Fig. 1 soll zunächst das Grundkonzept der Dosierspenderpumpe beschrieben werden, der allgemein aus einem Behälter 1, insbesondere in ovaler oder halbkreisförmiger Kartuschenform, und einer Pumpeinheit 2 besteht. Dabei können in einem Dosierspender zwei oder mehr derartiger Behälter 1 mit jeweils zugeordneter Pumpeinheit vorgesehen sein. In vorteilhafter Weise kann dabei die Einstellung der Mischung der einzelnen Komponenten in den Behältern 1 durch Verdrehen eines nicht dargestellten Stellelementes erfolgen. In vielen Anwendungsfällen reicht jedoch die fixe Einstellung des Mischungsverhältnisses auch aus. Die Ausgabe der Komponente aus dem jeweiligen Behälter 1 erfolgt hierbei durch Druck des Pumpkolbens 3 der Pumpeinheit 2 über ein Betätigungselement B, wie dies hier nur schematisch angedeutet ist. Der Pumpkolben 3 wirkt hierbei mit einem Pumpzylinder 6 zusammen, wie aus den Schnittdarstellungen der Fig. 1 ersichtlich ist und in Fig. 3 vergrößert dargestellt ist. Diese bevorzugt als sog. Druck-Saugpumpe ausgebildete Pumpeinheit 2 ist neuerungsgemäß in einer Hülse 7 eingesetzt, die den Behälter 1 im oberen Bereich fortsetzt. In fertigungstechnisch günstiger Weise ist die Hülse 7 zusammen mit dem Behälter 1 spritzgegossen, so dass sich eine stabile, integrale Bauweise ergibt. In den Ringraum zwischen Innenseite der Hülse 7 und Außenumfang des Pumpzylinders 6 ist zudem in einfacher Weise eine Schraubenfeder zur Rückstellung des Pumpkolbens 3 eingefügt.Based on the perspective view in Fig. 1 Let us first describe the basic concept of the metering dispenser pump, which generally consists of a container 1, in particular in an oval or semicircular cartridge shape, and a pumping unit 2. In this case, two or more such containers 1 may be provided with each associated pump unit in a metering dispenser. In an advantageous manner, the adjustment of the mixture of the individual components in the containers 1 can take place by turning an adjusting element (not shown). In many applications, however, the fixed setting of the mixing ratio is sufficient. The output of the component from the respective container 1 takes place here by pressure of the pump piston 3 of the pump unit 2 via an actuating element B, as is indicated only schematically here. The pump piston 3 acts together with a pump cylinder 6, as shown in the sectional views of Fig. 1 is apparent and in Fig. 3 is shown enlarged. This preferred as a so-called pressure-suction pump pump unit 2 is used according to the innovation in a sleeve 7, which continues the container 1 in the upper region. In manufacturing technology favorable manner, the sleeve 7 is injection molded together with the container 1, so that there is a stable, integral design. In the annular space between the inside of the sleeve 7 and the outer circumference of the pumping cylinder 6, a coil spring for returning the pump piston 3 is also inserted in a simple manner.

In der linken Schnittdarstellung von Fig. 1 ist der Pumpkolben 3 in nicht-betätigter Stellung gezeigt, während in der mittleren Darstellung der Pumpkolben 3 in den Pumpzylinder 6 niedergedrückt ist. Hierdurch wird das Volumen des Pumpraums 4a, so dass sich in Folge ein Einlassventil 4' öffnet und die Komponente aus dem Behälter 1 ansaugt und ein federbeaufschlagtes Auslassventil 4 öffnet. Dieses ist hier durch eine Kugel gebildet, die von einer Feder 5 gegen den zugehörigen Ventilsitz im Pumpkolben 3 niedergedrückt wird. Der Pumpkolben 3 und der Pumpzylinder 6 werden dabei innerhalb der Hülse 7 durch umlaufende Sicken 7' gehalten, die diese Bauteile durch Verrastung mit entsprechenden Abstufungen (vgl. Fig. 2 und 3) am Pumpzylinder 6 und Pumpkolben 3 in der Hülse 7 arretieren. Hierdurch ist der bevorzugt aus elastischem Kunststoff gebildete Pumpzylinder 6 in die Hülse 7 in abdichtender Weise fixiert bzw. eingepresst, wobei der Pumpzylinder 6 mit seiner Unterseite auch das Einlassventil 4', insbesondere in Form einer Membran, klemmt (vgl. Fig. 3, rechte Perspektivansicht).In the left section of Fig. 1 the pump piston 3 is shown in the non-actuated position, while in the middle illustration of the pump piston 3 is depressed in the pump cylinder 6. As a result, the volume of the pump chamber 4a, so that in sequence, an inlet valve 4 'opens and sucks the component from the container 1 and opens a spring-loaded outlet valve 4. This is formed here by a ball which is depressed by a spring 5 against the associated valve seat in the pump piston 3. The pump piston 3 and the pump cylinder 6 are held within the sleeve 7 by circumferential beads 7 ', which these components by latching with corresponding gradations (see. FIGS. 2 and 3 ) on the pump cylinder 6 and pump piston 3 in the sleeve 7 lock. As a result, the preferably formed of elastic plastic pump cylinder 6 is fixed in the sleeve 7 in a sealing manner or pressed, wherein the pump cylinder 6 with its bottom and the inlet valve 4 ', in particular in the form of a membrane, clamped (see. Fig. 3 , right perspective view).

In Fig. 2 ist der Pumpkolben 3 in Seitenansicht, Schnittdarstellung und Perspektivansicht dargestellt. Dabei ist der Aufbau der dem Auslassventil 4 zugeordneten Feder 5 ersichtlich, die an einem Federbügel 5a angeordnet ist, der bevorzugt mit dem Pumpkolben 3 einstückig spritzgegossen ist. Dabei kann am Federbügel 5a ein Filmscharnier 5b gebildet sein, um diesen umzuklappen und mit einem gegenüberliegenden Rastzapfen 5c in der Wandung des Pumpkolbens 3 zu verriegeln. Wie ersichtlich ist die Kunststoff-Feder 5 bevorzugt in Mäanderform am Federbügel 5a angeformt bzw. spritzgegossen, so dass sich eine Vorspannung ergibt und die Feder 5 bei Betätigung der Pumpeinheit 2 auf Block geht.In Fig. 2 the pump piston 3 is shown in side view, sectional view and perspective view. In this case, the structure of the exhaust valve 4 associated spring 5 can be seen, which is arranged on a spring clip 5a, which preferably integrally with the pump piston 3 injection molded. In this case, a film hinge 5b may be formed on the spring clip 5a in order to fold it over and lock it with an opposing catch pin 5c in the wall of the pump piston 3. As can be seen, the plastic spring 5 is preferably formed in a meandering shape on the spring clip 5a or injection molded, so that there is a bias and the spring 5 goes on actuation of the pump unit 2 to block.

In Fig. 3 ist der Pumpzylinder 6 in Perspektivansicht von oben und von unten dargestellt. Wie ersichtlich weist dieser einen Pumpraum 4a auf und am Außenumfang eine Gestaltung in Art einer Manschetten-Dichtung, um die Pumpeinheit 2 sicher gegenüber der Hülse 7 bzw. den Behälter 1 abzudichten, insbesondere während der Betätigung des Pumpkolbens 3, der dann in den Pumpraum 4a eintaucht. Es versteht sich von selbst, dass die hierbei aus dem Behälter 1 geförderte Komponente zu einer nicht-dargestellten Mischdüse weitergeleitet werden kann. Wie oben angedeutet, können in dem Dosierspender mehrere derartiger Behälter 1 mit jeweiliger Pumpeinheit 2 vorgesehen sein, so dass durch Mittelstellung eines Stellelementes die Pumpeinheiten 2 bei identischem Hub oder Fördervolumen je 50% der Gesamtausgabemenge liefern. Die Mischung enthält dann gleiche Teile der beiden (oder mehr) Komponenten aus beiden Behältern 1. Bei entsprechenden Zwischenlagen des Stellelementes können auch entsprechende Zwischenverhältnisse zwischen den Fördervolumina gewählt werden 6, so dass jede Komponente zwischen 0% bis 100% stufenlos veränderbar ist. Die Behälter 1 können auch flaschenartig oder in Art eines Beutels ausgebildet sein sowie unterschiedliche Querschnittsformen aufweisen.In Fig. 3 the pump cylinder 6 is shown in perspective view from above and from below. As can be seen, this has a pump space 4a and on the outer circumference a design in the manner of a sleeve seal to safely seal the pump unit 2 against the sleeve 7 and the container 1, in particular during the operation of the pump piston 3, which then into the pump chamber 4a dips. It goes without saying that the component conveyed from the container 1 in this case can be forwarded to a mixing nozzle (not shown). As indicated above, a plurality of such containers 1 with respective pumping unit 2 can be provided in the metering dispenser, so that by centering an actuating element, the pumping units 2 each deliver 50% of the total output quantity with identical stroke or delivery volume. The mixture then contains equal parts of the two (or more) components from both containers 1. With appropriate spacers of the control element and appropriate intermediate ratios between the delivery volumes can be selected 6, so that each component is continuously variable between 0% to 100%. The containers 1 can also be bottle-like or in the manner of a bag and have different cross-sectional shapes.

Wesentlich ist hierbei insbesondere die kompakte Bauweise, da die einzelnen Bauteile, insbesondere die Pumpeinheit 2 in die Hülse 7 integriert ist und bevorzugt in. Spritzgießtechnik kostengünstig hergestellt werden können sowie und durch Rast- oder Schnappverbindungen eine einfache Montage erzielt werden kann. Somit eignen sich die Behälter 1, insbesondere in Form einer ovalen Kartusche wie in Fig. 1 gezeigt, für verschiedene Stoffe, z. B. Kosmetika. Diese Pumpeinheit kann selbstverständlich auch als Einzelpumpe oder nicht einstellbarer Zweikomponentenspender für hoch viskose Produkte mit geringer Dosierung verwendet werden wie z. B. Rasiergel, Zweikomponentensilikon (Haftgel) oder Kleber.Essential here is in particular the compact design, since the individual components, in particular the pump unit 2 is integrated into the sleeve 7 and preferably in. Injection molding technology can be produced inexpensively and by snap-in or snap connections easy installation can be achieved. Thus, the container 1, in particular in the form of an oval cartridge as in Fig. 1 shown for different substances, eg. B. cosmetics. This pump unit can of course be used as a single pump or non-adjustable two-component dispenser for high-viscosity products with low dosage such. As shaving gel, two-component silicone (adhesive gel) or adhesive.
