Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Abgabevorrichtung anzugeben, die universell einsetzbar, einfach aufgebaut, robust ausgebildet, einfach bedienbar und/oder insbesondere überkopf benutzbar ist.The present invention has for its object to provide a dispensing device that is universally applicable, simple design, robust design, easy to use and / or in particular overhead can be used.

Die obige Aufgabe wird durch eine Abgabevorrichtung gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The above object is achieved by a dispensing device according to claim 1. Advantageous developments are the subject of the dependent claims.

Ein Aspekt liegt darin, daß die Abgabevorrichtung zumindest im wesentlichen entgegengesetzt zur Betätigungsrichtung die geförderte Flüssigkeit insbesondere im wesentlichen in der Mitte und entlang der Mittel- bzw. der Längsachse der Abgabevorrichtung ausgibt. Dies gestattet einen einfachen und kompakten Aufbau sowie eine universelle Anwendbarkeit.One aspect is that the dispensing device discharges the conveyed liquid at least substantially opposite to the actuating direction, in particular substantially in the middle and along the central or longitudinal axis of the dispensing device. This allows a simple and compact structure and a universal applicability.

Ein weiterer, auch unabhängig realisierbarer Aspekt liegt darin, mehrere Pumpräume mit elastischen bzw. flexiblen Pumpabschnitten vorzusehen, um gleichzeitig dieselbe Flüssigkeit ausgeben zu können. Insbesondere sind die Pumpräume parallel an ein die Flüssigkeit enthaltendes Behältnis angeschlossen oder anschließbar. Dies gestattet einen einfachen und robusten Aufbau. Beispielsweise ist die Abgabevorrichtung auch dann noch verwendbar, wenn eine der von den Pumpabschnitten gebildeten Pumpen ausfallen sollte, beispielsweise aufgrund eines nicht mehr öffnenden Einlaß- oder Auslaßventils. Des weiteren gestattet der Einsatz von mehreren Pumpabschnitten bzw. Pumpen eine Verringerung des Volumens der einzelnen Pumpräume, so daß insbesondere eine geringere Bauhöhe ermöglicht wird.Another aspect, which can also be implemented independently, is to provide a plurality of pump chambers with elastic or flexible pump sections in order to be able to dispense the same liquid at the same time. In particular, the pump chambers are connected or connectable in parallel to a container containing the liquid. This allows a simple and robust construction. For example, the dispenser is still usable even if one of the pumps formed by the pump sections should fail, for example due to a non-opening inlet or outlet valve. Furthermore, the use of several pump sections or pumps allows a reduction in the volume of the individual pump chambers, so that in particular a smaller overall height is made possible.

Bedarfsweise können die Pumpabschnitte bzw. die Pumpen auch nacheinander betätigt werden, beispielsweise über einen längeren Zeitraum, und/oder bei fortgesetzter Betätigung der Abgabevorrichtung eine weitere Ausgabe bzw. Fortsetzung der Ausgabe der Flüssigkeit ermöglichen.If required, the pump sections or the pumps can also be actuated one after the other, for example over a relatively long period of time, and / or, with continued actuation of the dispensing device, enable a further dispensing or continuation of the dispensing of the liquid.

Ein weiterer, auch unabhängig realisierbarer Aspekt sieht vor, daß die Abgabevorrichtung im Gebrauchszustand unten an einem Behältnis angeordnet und/oder die Abgaberichtung im wesentlichen vertikal nach unten gerichtet ist. Dies gestattet wiederum einen sehr einfachen und robusten Aufbau. Beispielsweise kann eine Saugleitung in das Behältnis entfallen. Weiter werden durch die Schwerkraft das Leeren des Behältnisses und insbesondere ein weitestgehendes vollständiges Leeren des Behältnisses unterstützt. Des weiteren gestattet dies eine sehr einfache und intuitive Bedienung, da die Abgabevorrichtung bzw. das Pumpteil insbesondere durch Niederdrücken der Abgabevorrichtung und/oder des Behältnisses zur Abgabe der Flüssigkeit betätigbar ist.Another aspect, which can also be realized independently, provides for the dispensing device to be arranged on the bottom of a container in the state of use and / or for the dispensing direction to be directed essentially vertically downwards. This in turn allows a very simple and robust construction. For example, a suction line can be omitted in the container. Further, the gravity of the emptying of the container and in particular a largely complete emptying of the container supported. Furthermore, this allows a very simple and intuitive operation, since the dispenser or the pumping part can be actuated in particular by depressing the dispensing device and / or the container for dispensing the liquid.

Ein weiterer, unabhängig realisierbarer Aspekt liegt darin, daß die Abgabevorrichtung mindestens ein vom Pumpteil getrennt angeordnetes Federelement aufweist, um die Rückstellung des Pumpabschnitts zu unterstützen oder zu bewirken. Dies gestattet einen einfachen und robusten Aufbau und eine besonders sichere Rückstellung des Pumpabschnitts.Another independent aspect that can be realized is that the dispenser has at least one spring element separated from the pumping part in order to assist or to effect the return of the pumping section. This allows a simple and robust construction and a particularly safe return of the pump section.

Ein Aspekt der vorliegenden Erfindung liegt darin, ein Ventilelement des Auslaßventils der Abgabevorrichtung hohl zur Ausgabe oder Umlenkung der Flüssigkeit in die Ausgaberichtung auszubilden, so daß das Ventilelement eine Abgabeöffnung bzw. Ausgabedüse der Abgabevorrichtung für die Flüssigkeit bildet. An das Ventilelement schließt sich dann kein weiterer Kanal, Kopf, Ausgaberüssel o. dgl. an. Vielmehr erfolgt unmittelbar vom Auslaßventil bzw. dessen Ventilelement die Ausgabe der Flüssigkeit. Dieses gestattet einen besonders einfachen, robusten und kompakten Aufbau. Insbesondere sind nur wenige Teile erforderlich, so daß auch eine einfache und kostengünstige Herstellung und Montage ermöglicht werden.One aspect of the present invention is to form a valve member of the discharge valve of the dispenser hollow for dispensing or deflecting the liquid in the dispensing direction, so that the valve member forms a dispensing nozzle of the dispenser for the liquid. At the valve element then no further channel, head, output key o. The like. Connects. Rather, the discharge of the liquid takes place directly from the outlet valve or its valve element. This allows a particularly simple, robust and compact design. In particular, only a few parts are required, so that a simple and cost-effective production and assembly are possible.

Ein weiterer, unabhängig realisierbarer Aspekt liegt darin, daß die Abgabevorrichtung bzw. deren Auslaßventil oder Abgabeöffnung oder Düse erst bei der erstmaligen Betätigung geöffnet wird. Dies gestattet eine einfache und unkomplizierte Handhabung, wobei insbesondere ein unerwünschtes vorzeitiges Auslaufen der Flüssigkeit bei der Lagerung oder beim Transport verhindert werden kann.Another independently feasible aspect is that the dispensing device or its outlet valve or dispensing opening or nozzle is opened only at the first actuation. This allows a simple and uncomplicated handling, in particular, an unwanted premature leakage of the liquid during storage or during transport can be prevented.

Ein weiterer, auch unabhängig realisierbarer Aspekt liegt darin, die Abgabevorrichtung mit einem Öffnungsmittel zu versehen, so daß beim Auswechseln eines zugeordneten Behältnisses dieses von dem Öffnungsmittel geöffnet und eine Flüssigkeitsverbindung zum Einlaßventil hergestellt wird. Dies ermöglicht eine einfache Handhabung.A further aspect, which can also be realized independently, is to provide the dispensing device with an opening means, so that when an associated container is exchanged, it is opened by the opening means and a fluid connection to the inlet valve is established. This allows easy handling.

Die vorschlagsgemäße Abgabevorrichtung kann beispielsweise für Luft-Zerstäuber, Air Freshener oder sonstige Anwendungen, beispielsweise zur Ausgabe eines Mediums aus einem flachen Glas, einem Becher, einer Schale o.dgl. benutzt werden. Die Abgabevorrichtung kann jeweils auch direkt in eine Schale, einen Becher o.dgl. eingesetzt werden. Die Ausgabe kann wahlweise in flüssiger und/oder zerstäubter Form erfolgen. Bedarfsweise kann auch zwischen den verschiedenen Ausgabeformen umgeschaltet werden.The proposed dispensing device can, for example, for air atomizer, Air Freshener or other applications, for example, to output a medium from a flat glass, a cup, a bowl or the like. to be used. The dispenser can each directly into a bowl, a cup or the like. be used. The output can be done either in liquid and / or atomized form. If necessary, it is also possible to switch between the different types of output.

Beim Darstellungsbeispiel weist das Behältnis 3 vorzugsweise einen kollabierbaren Beutel 3a insbesondere in einem starren Behälter 3b auf. Das Behältnis 3 bzw. der Behälter 3b ist vorzugsweise lösbar mit der Abgabevorrichtung 1 verbindbar oder umgekehrt. Insbesondere ist das Behältnis 3 wechselbar bzw. die Abgabevorrichtung 1 mehrfach verwendbar.In the illustrated example, the container 3 preferably has a collapsible bag 3a, in particular in a rigid container 3b. The container 3 or the container 3b is preferably detachably connected to the dispensing device 1 or vice versa. In particular, the container 3 is exchangeable or the dispensing device 1 can be used several times.

Fig. 5 zeigt eine Ausführungsvariante in einem zu Fig. 1 korrespondierenden Schnitt. Statt des Innenbeutels ist hier ein verschiebbarer Kolben 3c im Behälter 3b angeordnet. Fig. 5 shows an alternative embodiment in one Fig. 1 corresponding section. Instead of the inner bag, a displaceable piston 3c is arranged here in the container 3b.

Bei der Entnahme von Flüssigkeit 2 kollabiert der Beutel 3a (Fig. 1) bzw. verschiebt sich der Kolben 3c (Fig. 5). Hierzu weist vorzugsweise das Behältnis 3 bzw. der Behälter 3b vorzugsweise eine Belüftungsöffnung 3d auf, die beispielsweise von einem nicht dargestellten Etikett o.dgl. überdeckt sein kann, und entsprechend für einen Benutzer nicht sichtbar ist. Alternativ oder zusätzlich kann die Belüftungsöffnung 3d auch vom Benutzer oder selbsttätig durch die erstmalige Benutzung der Abgabevorrichtung 1 öffenbar sein. Alternativ kann die Belüftungsöffnung 3d auch in die Abgabevorrichtung 1 integriert sein.Upon removal of liquid 2, the bag 3a collapses (FIG. Fig. 1 ) or displaces the piston 3c ( Fig. 5 ). For this purpose, preferably the container 3 or the container 3b preferably has a ventilation opening 3d, the like, for example, from a label, not shown, or the like. can be covered, and accordingly not visible to a user. Alternatively or additionally, the ventilation opening 3d can also be opened by the user or automatically by the first-time use of the dispensing device 1. Alternatively, the ventilation opening 3d can also be integrated into the dispensing device 1.

Die Abgabevorrichtung 1 ist vorzugsweise derart ausgebildet, daß sie im Gebrauchszustand unten am Behältnis 3 angeordnet ist und/oder die Abgaberichtung A im wesentlichen vertikal nach unten verläuft. Jedoch kann die vorschlagsgemäße Abgabevorrichtung 1 grundsätzlich auch in jeder beliebigen Orientierung und/oder mit jeder beliebigen Abgaberichtung A und/oder auch zusammen mit sonstigen Behältnissen 3 oder auch ohne Behältnis 3 eingesetzt werden.The dispensing device 1 is preferably designed such that it is arranged in the use state at the bottom of the container 3 and / or the dispensing direction A extends substantially vertically downwards. However, the proposed dispensing device 1 can in principle be used in any orientation and / or with any dispensing direction A and / or together with other containers 3 or without container 3.

Die Abgabevorrichtung 1 weist besonders bevorzugt ein Öffnungsmittel, insbesondere in Form eines Anstechelements 3e, auf, um das Behältnis 3, insbesondere dessen Beutel 3a oder einen Verschluß des Behältnisses 3, wie eine Abdeckfolie 3f (Fig. 5), zu öffnen und dadurch eine Flüssigkeits- bzw. Fluidverbindung zwischen dem Behältnis 3 und der Abgabevorrichtung 1 herzustellen, so daß die Flüssigkeit 2 entnehmbar ist. Besonders bevorzugt wird durch das Öffnungsmittel eine sehr einfache Handhabung ermöglicht, da ein Aufsetzen bzw. Verbinden der Abgabevorrichtung 1 mit dem Behältnis 3 genügt, um das Behältnis 3 zu öffnen und fluidisch anzuschließen.The dispensing device 1 particularly preferably has an opening means, in particular in the form of a piercing element 3e, around the container 3, in particular its bag 3a or a closure of the container 3, such as a cover foil 3f (FIG. Fig. 5 ), and thereby establish a fluid or fluid connection between the container 3 and the dispenser 1, so that the liquid 2 can be removed. Particularly preferred is by the opening means allows a very simple handling, since a placement or connection of the dispensing device 1 with the container 3 is sufficient to open the container 3 and connect fluidly.

Die Abgabevorrichtung 1 ist vorzugsweise mit dem Behältnis 3 bzw. Behälter 3b verschraubbar oder rastend verbindbar. Jedoch ist es auch möglich, daß die Abgabevorrichtung 1 nicht mehr vom Behältnis 3 bzw. Behälter 3b lösbar ist. In diesem Fall ist die Abgabevorrichtung 1 beispielsweise damit verklebt, verschweißt und/oder verrastet.The dispensing device 1 is preferably connected to the container 3 or container 3b screwed or latching connected. However, it is also possible that the dispensing device 1 is no longer detachable from the container 3 or container 3b. In this case, the dispensing device 1, for example, glued to it, welded and / or locked.

Nachfolgend wird der bevorzugte Aufbau der Abgabevorrichtung 1 insbesondere unter Bezugnahme auf Fig. 2 bis 4 näher erläutert. Fig. 2 zeigt in einem vergrößerten Ausschnitt von Fig. 1 die Abgabevorrichtung 1, jedoch ohne Flüssigkeit 2 und ohne Beutel 3a. Fig. 3 zeigt die Abgabevorrichtung 1 in einem anderen Schnitt. Fig. 4 zeigt die Abgabevorrichtung 1 in einem weiteren Schnitt.Hereinafter, the preferred construction of the dispenser 1 will be described in particular with reference to FIG Fig. 2 to 4 explained in more detail. Fig. 2 shows in an enlarged section of Fig. 1 the dispensing device 1, but without liquid 2 and without bag 3a. Fig. 3 shows the dispenser 1 in a different section. Fig. 4 shows the dispensing device 1 in a further section.

Die Abgabevorrichtung 1 weist vorzugsweise ein erstes Bauteil 4, ein zweites Bauteil 5 und/oder mindestens ein vorzugsweise elastisch verformbares Pumpteil 6 bzw. einem elastisch verformbaren Pumpabschnitt 6a, beim Darstellungsbeispiel drei Pumpabschnitte 6a, auf. Nachfolgend wird primär auf die bevorzugte Ausbildung und Funktion eines Pumpabschnitts 6a abgestellt. Dies gilt für die weiteren Pumpabschnitte 6a vorzugsweise entsprechend.The dispensing device 1 preferably has a first component 4, a second component 5 and / or at least one preferably elastically deformable pump part 6 or an elastically deformable pump section 6a, in the illustrated example three pump sections 6a. In the following, the focus is primarily on the preferred design and function of a pump section 6a. This preferably applies correspondingly to the further pump sections 6a.

Das Pumpteil 6 bzw. zweite Bauteil 5 ist mit dem ersten Bauteil 4 vorzugsweise unlösbar, flüssigkeitsdicht und insbesondere gasdicht verbunden bzw. verbindbar.The pump part 6 or second component 5 is preferably insoluble with the first component 4, liquid-tight and in particular gas-tight connected or connectable.

Das erste und/oder zweite Bauteil 4, 5 ist vorzugsweise starr und/oder einstückig ausgebildet, insbesondere aus einem geeigneten, vorzugsweise lebensmittelechten Kunststoff, insbesondere einem Polyolefin, wie PP (Polypropylen) oder PE (Polyethylen), gespritzt oder in sonstiger Weise hergestellt. Das Pumpteil 6 bzw. der Pumpabschnitt 6a ist demgegenüber weich bzw. flexibel oder elastisch verformbar ausgebildet.The first and / or second component 4, 5 is preferably rigid and / or integral, in particular made of a suitable, preferably food safe plastic, in particular a polyolefin, such as PP (polypropylene) or PE (polyethylene), sprayed or produced in any other way. In contrast, the pump part 6 or the pump section 6a is designed to be soft, flexible or elastically deformable.

Das zweite Bauteil 5 dient vorzugsweise einer Befestigung bzw. Halterung des Pumpteils 6. Besonders bevorzugt ist das Pumpteil 6 vom zweiten Bauteil 5 gebildet oder an dieses angeformt oder umgekehrt.The second component 5 preferably serves for fastening or holding the pump part 6. The pump part 6 is particularly preferably formed by the second component 5 or formed on it or vice versa.

Beim Darstellungsbeispiel ist das zweite Bauteil 5 vorzugsweise an das Pumpteil 6 angespritzt oder in sonstiger Weise unlösbar und flüssigkeitsdicht damit verbunden. Dies ermöglicht eine einfache Herstellung, beispielsweise durch die sogenannte "Bi-Injection", also insbesondere Anspritzen eines weiteren Materials in der gleichen Spritzform, in der ein erstes Material geformt wird. Insbesondere wird so eine chemische und/oder mechanische Verbindung ermöglicht.In the illustrated example, the second component 5 is preferably injection-molded onto the pumping part 6 or otherwise insoluble and fluid-tightly connected thereto. This allows a simple production, for example by the so-called "bi-injection", ie in particular injection molding of a further material in the same injection mold, in which a first material is formed. In particular, such a chemical and / or mechanical connection is made possible.

Alternativ oder zusätzlich kann das zweite Bauteil 5 mit dem Pumpteil 6 auch durch eine Hinterschneidung, Ausnehmung, Durchbrechung, Überlappung o. dgl. verbunden oder gehalten sein. Weiter können das Pumpteil 6 und das zweite Bauteil 5 auch als getrennte Bauteile ausgebildet bzw. hergestellt sein.Alternatively or additionally, the second component 5 can be connected or held to the pump part 6 by an undercut, recess, opening, overlap or the like. Furthermore, the pump part 6 and the second component 5 can also be designed or manufactured as separate components.

Besonders bevorzugt ist zwischen dem ersten Bauteil 4 und dem Pumpteil 6 bzw. Pumpabschnitt 6a ein Aufnahme- oder Pumpraum P für die Flüssigkeit 2 gebildet oder davon - zumindest teilweise - begrenzt.Particularly preferably, a receiving or pumping space P for the liquid 2 is formed between the first component 4 and the pumping part 6 or pumping portion 6a or is delimited therefrom - at least partially.

Vorzugsweise ist der Pumpabschnitt 6a zumindest im wesentlichen dom- oder halbkugelartig oder gewölbt ausgebildet und/oder weist das erste Bauteil 4 einen dazu korrespondierenden bzw. demgegenüberliegenden, insbesondere vertieften Bereich 4a auf, um den Pumpraum P zu bilden bzw. zu begrenzen. Besonders bevorzugt weist das vorzugsweise einstückig ausgebildete Pumpteil 6 bzw. zweite Bauteil 5 mehrere, insbesondere drei derartige Pumpabschnitte 6a auf, die entsprechend drei Pumpkammern P bilden. Das erste Bauteil 4 weist vorzugsweise dazu korrespondierend drei vertiefte Bereiche 4a auf, die in den Fig. 2 bis 4 zumindest im wesentlichen kuppelartig angedeutet sind.Preferably, the pump portion 6a is formed at least substantially dom- or hemispherical or curved and / or the first component 4 has a corresponding thereto or opposite, in particular recessed portion 4a, to form the pump space P or limit. The preferably integrally formed pumping part 6 or second component 5 particularly preferably has several, in particular three, such pumping sections 6 a, which correspondingly form three pumping chambers P. The first component 4 preferably has corresponding thereto three recessed areas 4a, which in the Fig. 2 to 4 are indicated at least substantially dome-like.

Beim Darstellungsbeispiel sind vorzugsweise mehrere oder alle Pumpräume P an dasselbe bzw. ein gemeinsames Flüssigkeitsreservoir angeschlossen und dienen dem Pumpen und Fördern derselben Flüssigkeit 2.In the illustrated example, preferably several or all pump chambers P are connected to the same or a common liquid reservoir and serve for pumping and conveying the same liquid 2.

Das zweite Bauteil 5 ist, wie bereits erwähnt, verhältnismäßig starr ausgebildet. Demgegenüber ist bzw. sind das Pumpteil 6 bzw. die Pumpteile 6 - zumindest der Pumpabschnitt 6a bzw. die Pumpabschnitte 6a - elastisch verformbar bzw. flexibel ausgebildet, um die gewünschte Verformung zur Verkleinerung des Pumpraums P bzw. der Pumpräume P zum Pumpen bzw. Fördern der Flüssigkeit 2 zu ermöglichen. Die unterschiedlichen Materialien sind, wie bereits erwähnt, vorzugsweise derart miteinander verbunden, daß dadurch letztendlich ein Bauteil gebildet wird. Dies erleichtert die Montage wesentlich. Insbesondere genügt es dann, das zweite Bauteil 5 mit dem ersten Bauteil 4 zu verbinden. Dies erfolgt vorzugsweise durch Ultraschallschweißen und/oder auf sonstige geeignete Weise.The second component 5 is, as already mentioned, relatively rigid. In contrast, the pump part 6 or the pump parts 6 is or are at least the pump section 6a or the pump sections 6a - elastically deformable or flexible designed to allow the desired deformation to reduce the pumping space P and the pump chambers P for pumping or conveying the liquid 2. The different materials are, as already mentioned, preferably connected to each other in such a way that ultimately a component is formed. This facilitates the assembly significantly. In particular, it is then sufficient to connect the second component 5 to the first component 4. This is preferably done by ultrasonic welding and / or in any other suitable manner.

Die Abgabevorrichtung 1 weist vorzugsweise ein Einlaßventil 7 und ein Auslaßventil 8 auf. Vorzugsweise bildet das Pumpteil 6 zusammen mit dem ersten Bauteil 4 das Einlaßventil 7 und/oder Auslaßventil 8. Jedoch können die Ventile 7, 8 auch separat gebildet sein. Die Ventile 7, 8 sind vorzugsweise als selbst schließende Einwegeventile ausgebildet.The dispensing device 1 preferably has an inlet valve 7 and an outlet valve 8. Preferably, the pump member 6 forms together with the first component 4, the inlet valve 7 and / or outlet valve 8. However, the valves 7, 8 may also be formed separately. The valves 7, 8 are preferably designed as self-closing one-way valves.

Wenn der Pumpraum P mit Flüssigkeit 2 gefüllt ist, kann ausgehend von der in den Figuren gezeigten Ruhe- bzw. Ausgangsstellung durch Verformen des zugeordneten Pumpabschnitts 6a das Volumen des jeweiligen Pumpraums P verkleinert und dadurch Flüssigkeit 2 aus dem Pumpraum P verdrängt und ausgegeben werden. Insbesondere wird hierzu vorzugsweise ein Betätigungselement 9, besonderes bevorzugt eine die Abgabevorrichtung 1 tragende Oberfläche (beispielhaft in Fig. 2 angedeutet), eine nicht dargestellte Kappe o.dgl., in eine Betätigungsrichtung B relativ zum ersten Bauteil 4 bewegt, insbesondere durch Niederdrücken der Abgabevorrichtung 1 bzw. des Behältnisses 3 in Richtung N, und dadurch der Pumpabschnitt 6a zumindest bereichsweise verformt und der Pumpraum P verkleinert.When the pump space P is filled with liquid 2, starting from the rest or initial position shown in the figures, the volume of the respective pump space P can be reduced by deforming the associated pump section 6a, thereby displacing liquid 2 from the pump space P and outputting it. In particular, for this purpose, preferably an actuating element 9, more preferably a surface carrying the dispensing device 1 (exemplified in Fig. 2 , an unillustrated cap or the like, moved in an actuating direction B relative to the first component 4, in particular by depressing the dispenser 1 and the container 3 in the direction N, and thereby the pump portion 6a at least partially deformed and the pump space P reduced.

Das Auslaßventil 8 bzw. die Düse 17 ist vorzugsweise zumindest im wesentlichen in der Mitte der Abgabevorrichtung 1 und/oder zwischen den Pumpteilen 6 bzw. den Pumpkammern P angeordnet.The outlet valve 8 or the nozzle 17 is preferably arranged at least substantially in the center of the dispensing device 1 and / or between the pumping parts 6 and the pumping chambers P.

Wie bereits erwähnt, erfolgt eine Betätigung der Abgabevorrichtung 1 bzw. mindestens eines Pumpabschnitts 6a, besonders bevorzugt mehrerer oder aller Pumpabschnitte 6a, durch Niederdrücken der Abgabevorrichtung 1 bzw. des Behältnisses 3.As already mentioned, the dispensing device 1 or at least one pump section 6a, particularly preferably several or all pump sections 6a, is actuated by depressing the dispensing device 1 or the container 3.

Jedoch ist es beispielsweise auch möglich, daß zur Ausgabe von Flüssigkeit 2 ein nicht dargestellter Benutzer unmittelbar auf den Pumpabschnitt 6a drückt oder ein sonstiger Gegenstand darauf gedrückt wird bzw. einwirkt.However, it is also possible, for example, for the dispensing of liquid 2, to press an unillustrated user directly onto the pump section 6a or to press or act upon another object.

Beim Verformen des Pumpabschnitts 6a und Verkleinern des Pumpraums P wird die Flüssigkeit 2 wird über das Auslaßventil 8 aus- bzw. abgegeben. Das Öffnen des Auslaßventils 8 erfolgt insbesondere selbsttätig, vorzugsweise aufgrund des Flüssigkeitsdrucks, und/oder - ggf. zusätzlich - aufgrund einer entsprechenden Verformung des Pumpabschnitts 6a beim Betätigen.When the pump section 6a is deformed and the pumping space P is reduced, the liquid 2 is discharged via the outlet valve 8. The opening of the outlet valve 8 takes place in particular automatically, preferably due to the fluid pressure, and / or - possibly in addition - due to a corresponding deformation of the pump section 6a during actuation.

Beim Darstellungsbeispiel ist das Auslaßventil 8 vorzugsweise seitlich neben den Pumpabschnitten 6a, insbesondere in der Mitte, angeordnet.In the illustrated example, the outlet valve 8 is preferably arranged laterally next to the pump sections 6a, in particular in the middle.

Das Auslaßventil 8 weist vorzugsweise ein Ventilelement 10 auf, das insbesondere einstückig mit dem Pumpteil 6 ausgebildet ist. Das Ventilelement 10 ist beim Darstellungsbeispiel vorzugsweise von einem Verbindungsabschnitt 11 gehalten und vorzugsweise mit dem Pumpteil 6 verbunden. Der Verbindungsabschnitt 11 umgibt das Ventilelement 10 vorzugsweise ringförmig bzw. flanschartig. Der Verbindungsabschnitt 11 hält das Ventilelement 10 vorzugsweise an einem zugeordneten Ventilsitz 12 des Auslaßventils 8. Beim Darstellungsbeispiel ist der Ventilsitz 12 insbesondere ringförmig bzw. als Konusring ausgebildet. Besonders bevorzugt ist der Ventilsitz 12 als Stirnfläche einer endseitig geschlossenen Ausnehmung 13 ausgeführt und/oder vom ersten Bauteil 4 gebildet, insbesondere darin eingeformt.The outlet valve 8 preferably has a valve element 10, which is in particular formed integrally with the pump part 6. The valve element 10 is preferably held in the illustrated example by a connecting portion 11 and preferably connected to the pump part 6. The connecting portion 11 surrounds the valve element 10 preferably annular or flange. The connecting portion 11 holds the valve element 10 preferably at an associated valve seat 12 of the exhaust valve 8. In the illustrated example, the valve seat 12 is in particular annular or formed as a cone ring. Particularly preferably, the valve seat 12 is designed as an end face of a closed-end recess 13 and / or formed by the first component 4, in particular formed therein.

Das Öffnen des Auslaßventils 8 erfolgt insbesondere durch axiale Bewegung des Ventilelements 10. Dies ist insbesondere durch elastische Verformung des Verbindungsabschnitts 11 oder sonstiger variabler Bereiche möglich.The opening of the outlet valve 8 takes place in particular by axial movement of the valve element 10. This is possible in particular by elastic deformation of the connecting portion 11 or other variable areas.

Das Auslaßventil 8 ist vorzugsweise über einen Anschlußkanal 14 und/oder einen den Ventilsitz 12 radial außen, peripher umgebenden Ringkanal 15 an die zugeordnete Pumpkammer P, vorzugsweise parallel an alle Pumpkammern P, angeschlossen. Beim Pumpen bzw. Betätigen des Pumpteils 6 bzw. der Pumpteile 6 wird in den Pumpräumen P befindliche Flüssigkeit 2 unter Druck gesetzt und führt insbesondere zu einer derartigen Verformung des Verbindungsabschnitts 11, daß das Ventilelement 10 axial vom Ventilsitz 12 abgehoben wird, also das Auslaßventil 8 öffnet, Die Flüssigkeit 2 kann dann insbesondere radial in die Ausnehmung 13 strömen.The outlet valve 8 is preferably connected via a connecting channel 14 and / or a valve seat 12 radially outwardly, peripherally surrounding annular channel 15 to the associated pumping chamber P, preferably parallel to all pumping chambers P, connected. When pumping or actuating the pumping part 6 or the pumping parts 6, liquid 2 in the pumping chambers P is pressurized and in particular leads to such a deformation of the connecting section 11, that the valve element 10 is lifted axially from the valve seat 12, so the exhaust valve 8 opens, the liquid 2 can then flow radially into the recess 13 in particular.

Die Abgabevorrichtung 1 weist des weiteren vorzugsweise einen Ausgabekanal 16 und/oder eine Düse 17 auf. Der Ausgabekanal 16 und/oder die Düse 17 ist von dem Ventilelement 10 gebildet. Das Ventilelement 10 ist hierzu hohl ausgebildet und/oder mit einen entsprechenden, insbesondere axial bzw. in Bewegungsrichtung bzw. in Abgaberichtung A verlaufenden Durchgangskanal versehen. Anstelle der gebildeten Düse 17, beim Darstellungsbeispiel eine Flachdüse, kann die Abgabevorrichtung 1 bzw. das Auslaßventil 8 bzw. das Ventilelement 10 auch lediglich eine beispielsweise nur vom Ausgabekanal 16 gebildete Abgabeöffnung aufweisen.The dispensing device 1 further preferably has an output channel 16 and / or a nozzle 17. The output channel 16 and / or the nozzle 17 is formed by the valve element 10. For this purpose, the valve element 10 is hollow and / or provided with a corresponding, in particular axially or in the direction of movement or in discharge direction A extending through channel. Instead of the nozzle 17 formed, in the illustrated example a flat nozzle, the dispensing device 1 or the outlet valve 8 or the valve element 10 can also have only one dispensing opening formed, for example, only by the dispensing channel 16.

Bei geöffnetem Auslaßventil 8 bzw. vom Ventilsitz 12 abgehobenem Ventilelement 10 wird die in die Ausnehmung 13 strömende Flüssigkeit 2 insbesondere umgelenkt und durch das Ventilelement 10 hindurch bzw. durch den Ausgabekanal 16, eine davon gebildete Abgabeöffnung und/oder die Düse 17 ausgegeben. Beim Darstellungsbeispiel dient also das Auslaßventil 8 bzw. Ventilelement 10 einer mittelbaren Ausgabe oder Abgabe der Flüssigkeit 2. Insbesondere schließen sich also keine weiteren Kanäle, Umlenkungen, Ausgaberüssel o.dgl. an das Auslaßventil 8 bzw. dessen Ventilelement 10 an, obwohl dies grundsätzlich auch möglich ist und dementsprechend vorzugsweise nicht ausgeschlossen werden soll.When the outlet valve 8 is open or the valve element 10 is lifted off the valve seat 12, the liquid 2 flowing into the recess 13 is in particular deflected and dispensed through the valve element 10 or through the dispensing channel 16, a dispensing opening formed therefrom and / or the nozzle 17. In the illustrated example, therefore, the outlet valve 8 or valve element 10 serves for an indirect dispensing or dispensing of the liquid 2. In particular, therefore, no further channels, deflections, dispensing spouts or the like are closing. to the outlet valve 8 and its valve element 10, although this is in principle also possible and accordingly preferably should not be excluded.

Besonders bevorzugt wird die Abgabevorrichtung 1 bzw. deren Auslaßventil 8 oder die Abgabeöffnung bzw. Düse 17 erst bei der erstmaligen Betätigung geöffnet. Insbesondere wird beispielsweise die Düse 17 im Bereich ihrer Austragsöffnung bzw. Spitze mit einer sehr dünnen Wandung 18 bei der Herstellung versehen. Erst bei der erstmaligen Betätigung bzw. Flüssigkeitsausgabe führt der Flüssigkeitsdruck dazu, daß die genannte dünne Wandung 18 aufreißt und dadurch die Düse 17 bzw. die Flüssigkeitsausgabe bzw. die Abdeckvorrichtung 1 geöffnet wird. Jedoch sind hier auch andere konstruktive Lösungen möglich, um den gewünschten Effekt zu erreichen.Particularly preferably, the dispensing device 1 or its outlet valve 8 or the discharge opening or nozzle 17 is opened only at the first actuation. In particular, for example, the nozzle 17 is provided in the region of its discharge opening or tip with a very thin wall 18 during manufacture. Only at the first actuation or liquid output of the liquid pressure causes the said thin wall 18 tears open and thereby the nozzle 17 and the liquid dispensing or the cover device 1 is opened. However, other constructive solutions are possible here to achieve the desired effect.

Die Abgaberichtung A verläuft vorzugsweise zumindest entgegengesetzt zur Betätigungsrichtung B und/oder zumindest im wesentlichen parallel zur und/oder in der Mittelachse M der Abgabevorrichtung 1 und/oder zumindest im wesentlichen parallel zur und/oder in der Längsachse L des Behältnisses 3 (vgl. Fig. 1 und 2).The dispensing direction A preferably runs at least opposite to the actuating direction B and / or at least substantially parallel to and / or in the center axis M of the dispensing device 1 and / or at least substantially parallel to and / or in the longitudinal axis L of the container 3 (cf. Fig. 1 and 2 ).

Nach der Flüssigkeitsabgabe bzw. entsprechendem Abfall des Flüssigkeitsdrucks in den Pumpkammern P bzw. in dem Ringkanal 15 schließt das Auslaßventil 8 vorzugsweise wieder selbsttätig, insbesondere aufgrund der Rückstellkräfte des Verbindungsabschnitts 11. Jedoch sind hier auch andere konstruktive Lösungen möglich. Bedarfsweise kann auch eine Rückstellfeder o.dgl. eingesetzt werden.After the liquid discharge or corresponding drop in the fluid pressure in the pumping chambers P or in the annular channel 15, the outlet valve 8 closes again preferably automatically, in particular due to the restoring forces of the connecting portion 11. However, other design solutions are possible here. If necessary, a return spring or the like. be used.

Nach Beendigung der Flüssigkeitsausgabe - insbesondere nach Beendigung des Niederdrückens des Behältnisses 3 bzw. der Abgabevorrichtung 1 bzw. nach Loslassen des Behältnisses 3 bzw. der Abgabevorrichtung 1 - erfolgt ein vorzugsweise selbsttätiges Rückstellen des Pumpabschnitts 6a bzw. der Pumpabschnitte 6a in die in den Figuren gezeigte Ausgangslage, wobei neue Flüssigkeit 2 über das Einlaßventil 7 bzw. die Einlaßventile 7 in den Pumpraum P bzw. die Pumpräume P aufgenommen wird, insbesondere eingesaugt wird. Das Öffnen der Einlaßventile 7 während des Rückstellens erfolgt insbesondere aufgrund des dabei in den Pumpräumen P herrschenden Unterdrucks.After completion of the liquid dispensing - in particular after completion of the depression of the container 3 or the dispenser 1 or after releasing the container 3 or the dispensing device 1 - takes a preferably automatic resetting of the pump section 6a and the pump sections 6a in the shown in the figures Starting position, wherein new liquid 2 is taken over the inlet valve 7 and the inlet valves 7 in the pump chamber P and the pump chambers P, in particular, is sucked. The opening of the intake valves 7 during the reset takes place in particular due to the pressure prevailing in the pump chambers P negative pressure.

Gemäß einem bevorzugten Aspekt weist die Abgabevorrichtung 1 mindestens ein Federelement 19 auf, das insbesondere getrennt vom Pumpabschnitt 6a bzw. den Pumpabschnitten 6a angeordnet und ausgebildet ist und unmittelbar auf das Betätigungselement 9 in die Rückstellrichtung R - also in axialer Richtung bzw. Betätigungsrichtung B federnd - wirkt, um die Rückstellung des Pumpabschnitts 6a bzw. der Pumpabschnitte 6a zu unterstützen oder zu bewirken.According to a preferred aspect, the dispensing device 1 has at least one spring element 19, which is arranged and configured in particular separately from the pump section 6a or the pump sections 6a and directly on the actuating element 9 in the return direction R - that is resilient in the axial direction or actuation direction B - acts to assist or cause the return of the pumping section 6a and the pumping sections 6a, respectively.

Vorzugsweise ist das Federelement 19 bügelartig oder bogenartig ausgebildet. Jedoch sind hier auch beliebige andere Formen möglich.Preferably, the spring element 19 is bow-shaped or arc-shaped. However, any other shapes are possible here as well.

Vorzugsweise entspricht die Höhe bzw. axiale Erstreckung des Federelements 19 im wesentlichen derjenigen der Pumpabschnitte 6a und/oder weist das Federelement 19 in die gleiche Richtung bzw. in axialer Richtung.Preferably, the height or axial extent of the spring element 19 substantially corresponds to that of the pump sections 6a and / or has the spring element 19 in the same direction or in the axial direction.

Besonders bevorzugt ist das Federelement 19 an der Abdeckvorrichtung 1 insbesondere dem zweiten Bauteil 5 oder Pumpteil 6 angeordnet und insbesondere einstückig damit ausgebildet, vorzugsweise angeformt oder angespitzt.Particularly preferably, the spring element 19 is arranged on the cover device 1, in particular the second component 5 or pump part 6, and in particular integrally formed therewith, preferably molded or sharpened.

Vorzugsweise sind mehrere Federelemente 19 vorgesehen, die insbesondere peripher entlang des Umfangs der Abdeckvorrichtung 1 verteilt und/oder derart diametral gegenüberliegend angeordnet sind, daß die Abgabevorrichtung 1 - auch bei einem sehr langen und/oder schweren Behältnis 3 bzw. Behälter 3b - eine gute Standfestigkeit aufweist.Preferably, a plurality of spring elements 19 are provided, which are distributed in particular peripherally along the circumference of the cover device 1 and / or arranged diametrically opposite, that the dispensing device 1 - even with a very long and / or heavy container 3 or container 3b - a good stability having.

Besonders bevorzugt sind die Federelemente 19 radial außerhalb und/oder um den Pumpabschnitt 6a bzw. die Pumpabschnitte 6a und/oder das Auslaßventil 8 herum angeordnet.The spring elements 19 are particularly preferably arranged radially outside and / or around the pump section 6a or the pump sections 6a and / or the outlet valve 8.

Beim Darstellungsbeispiel weist das zweite Bauteil 5 mindestens einen, vorzugsweise stegartigen Vorsprung 20 auf, der in eine Nut 21 im ersten Bauteil 4 eingreift und mit dieser - insbesondere durch Ultraschallschweißen - flüssigkeitsdicht verbunden ist.In the illustrated example, the second component 5 has at least one preferably web-like projection 20, which engages in a groove 21 in the first component 4 and is connected to it in a liquid-tight manner, in particular by ultrasonic welding.

Besonders bevorzugt weist das zweite Bauteil 5 auf der dem Vorsprung 20 abgewandten Seite und gegenüberliegend eine Erhebung 22 auf, die das Aufsetzen eines nicht dargestellten Übertragungselement zur Ultraschalleinleitung und damit eine Fokussierung des Ultraschalls auf den gewünschten, zu verbindenden Bereich erleichtert. Die gebildete flüssigkeitsdichte Verbindung erstreckt sich insbesondere um das Pumpteil 6 bzw. die Pumpabschnitte 6a herum.Particularly preferably, the second component 5 on the side facing away from the projection 20 and opposite a survey 22, which facilitates the placement of a transmission element, not shown, for ultrasonic introduction and thus a focusing of the ultrasound to the desired area to be connected. The formed liquid-tight connection extends in particular around the pump part 6 or the pump sections 6a.

Beim Darstellungsbeispiel ist vorzugsweise jedem Pumpraum P ein separates Einlaßventil 7 zugeordnet. Insbesondere ist hierzu am ersten Bauteil 4 bzw. an den Bereichen 4a jeweils ein Ventilsitzbereich 23 mit einer Ventilöffnung 24 zum Behältnis 3 hin zur Aufnahme von Flüssigkeit 2 gebildet. Weiter ist vorzugsweise am Pumpteil 6 oder separat jeweils ein Ventillappen 25 angeordnet, insbesondere vom Pumpteil 6 einstückig damit ausgebildet oder davon gebildet, und insbesondere blattfederartig bzw. elastisch gegen den Ventilsitzbereich 23 zur Abdeckung bzw. zum Verschließen der Ventilöffnung 24 vorgespannt, wie in Fig. 4 für einen Pumpraum P angedeutet. Der Ventillappen 25 liegt also auf der Innenseite des Pumpraums P am Ventilsitzbereich 23 an.In the illustrated example, preferably each pump chamber P is assigned a separate intake valve 7. In particular, for this purpose, in each case a valve seat region 23 with a valve opening 24 to the container 3 towards the reception of liquid 2 is formed on the first component 4 or on the regions 4 a. Further, a valve flap 25 is preferably arranged on the pump part 6 or separately, in particular formed integrally therefrom or formed by the pump part 6, and in particular biased against the valve seat area 23 to cover or close the valve opening 24, as in FIG Fig. 4 for a pump space P indicated. The valve flap 25 thus abuts the valve seat region 23 on the inside of the pump chamber P.

Beim Rückstellen der Pumpabschnitte 6a in die in den Figuren gezeigte Ausgangslage ist das Auslaßventil 8 geschlossen. Dementsprechend wird in den Pumpräumen P ein Unterdruck gebildet, so daß die Ventillappen 25 nach innen öffnen und damit die Ventilöffnungen 24 freigeben, die Einlaßventile 7 also öffnen. Bei der bevorzugten Anordnung der Abgabevorrichtung 1 am unteren Ende des Behältnisses 3 ist die Gravitationskraft dem Füllen der Pumpräume P mit der Flüssigkeit 2 beim Rückstellen zuträglich. Des weiteren kann eine zumindest weitestgehend vollständige Entleerung erreicht werden.When returning the pump sections 6a in the starting position shown in the figures, the exhaust valve 8 is closed. Accordingly, a negative pressure is formed in the pump chambers P, so that the valve tabs 25 open inwardly and thus release the valve openings 24, the intake valves 7 thus open. In the preferred arrangement of the dispenser 1 at the lower end of the container 3, the gravitational force is beneficial to the filling of the pump chambers P with the liquid 2 during the recovery. Furthermore, an at least largely complete emptying can be achieved.

Bedarfsweise können an den Ventilsitzbereichen 23 außenseitig zusätzlich Kanäle 26 vorgesehen sein, um eine möglichst vollständige Leerung des Behältnisses 3 zu unterstützen.If desired, additional channels 26 can be provided on the outside of the valve seat regions 23 in order to support the most complete possible emptying of the container 3.
