Description

Die Erfindung betrifft ein Set, umfassend einen Spender für ein pumpfähiges Medium, mit einer in einem Gehäuseoberteil angeordneten Ausgabeeinrichtung, an dem gehäuseseitige Elemente eines Bajonettverschlusses vorgesehen sind, und einen mit der Ausgabeeinrichtung strömungsverbindbaren, das pumpfähiige Medium enthaltenden Behälter, der durch eine Membran verschlossen ist, die beim Ansetzen des Behälters an den Gehäuseoberteil durch einen Ansaugstutzen der Ausgabeeinrichtung perforierbar ist. Der Spender ist insbesondere zur portionierten Abgabe von Seife, Seifenschaum Desinfektionsmittel, Creme oder dergleichen pumpfähigen Medien für den Haushalt und den privaten Gebrauch vorgesehen.The invention relates to a set comprising a dispenser for a pumpable medium, with an output device arranged in a housing upper part, on which housing-side elements of a bayonet lock are provided, and a container which is flow-connectable to the output device and contains the pumpable medium and which is closed by a membrane , which can be perforated when the container is attached to the upper housing part through a suction nozzle of the dispensing device. The dispenser is intended in particular for the portioned dispensing of soap, foam soap, disinfectant, cream or similar pumpable media for household and private use.

Ein derartiges Set ist beispielsweise aus der WO 2015/178913 bekannt. Das Gehäuse des Spenders umfasst einen eine Hubkolbenpumpe enthaltenden Oberteil und einen mit dem Oberteil verbindbaren Unterteil, in den ein das abzugebende Medium enthaltender Behälter - insbesondere eine austauschbare Nachfüllung - eingesetzt ist. Der Behälter ist durch eine Membran an der Oberseite verschlossen und weist einen mit Vorsprüngen versehenen oberen Flansch auf, der in den mit entsprechenden Ausnehmungen versehenen oberen Rand des Unterteils eingreift, sodass der Behälter im Unterteil verdrehfest angeordnet ist. Vom Oberteil steht ein angespitztes Ansaugrohr nach unten, das beim Aufsetzen des Oberteiles auf den Unterteil die Membran durchsticht. Zwischen dem Oberteil und dem Unterteil ist ein Gewinde oder ein Bajonettverschluss vorgesehen, sodass die beiden Teile miteinander verbunden werden können. Bei diesem Set kann der mit dem Medium gefüllte Behälter in den Unterteil eingesetzt werden, der eine Art von Übertopf darstellt. Es ist aber auch möglich, z. B. wenn gerade keine Nachfüllung vorhanden ist, das flüssige Medium direkt in den Unterteil einzufüllen und auf diesen den Oberteil mit der Pumpe aufzusetzen.Such a set is for example from the WO 2015/178913 known. The housing of the dispenser comprises an upper part containing a reciprocating piston pump and a lower part which can be connected to the upper part and into which a container containing the medium to be dispensed - in particular an exchangeable refill - is inserted. The container is closed by a membrane at the top and has an upper flange provided with projections which engages in the upper edge of the lower part which is provided with corresponding recesses, so that the container is arranged in the lower part in a rotationally fixed manner. From the upper part there is a pointed suction pipe which pierces the membrane when the upper part is placed on the lower part. A thread or a bayonet lock is provided between the upper part and the lower part so that the two parts can be connected to one another. With this set, the container filled with the medium can be inserted into the lower part, which is a kind of planter. But it is also possible, for. B. if there is currently no refill, fill the liquid medium directly into the lower part and place the upper part with the pump on this.

Die Erfindung hat es sich nun zur Aufgabe gestellt, ein Set der eingangs genannten Art zur Verfügung zu stellen, in dem der das pumpfähige, flüssige oder pastöse Medium enthaltende Behälter, insbesondere in Form einer austauschbaren Nachfüllung, unabhängig von einem Gehäuseunterteil in Art eines Übertopfes mit dem Gehäuseoberteil verbunden werden kann.The invention has now set itself the task of providing a set of the type mentioned above, in which the container containing the pumpable, liquid or pasty medium, in particular in the form of an exchangeable refill, independently of a lower housing part in the form of a cachepot can be connected to the upper part of the housing.

Erfindungsgemäß wird dies dadurch erreicht, dass der Bajonettverschluss zwischen dem Gehäuseoberteil und dem Behälter vorgesehen ist.According to the invention, this is achieved in that the bayonet lock is provided between the upper housing part and the container.

Die direkte Verbindung des mit dem pumpfähigen Medium gefüllten Behälters mit dem Gehäuse wirkt sich auch vorteilhaft auf die Abdichtung zwischen dem Behälter und der Ausgabeeinrichtung aus, die insbesondere bei formstabilen Behältern notwendig ist, um das Medium ansaugen zu können.The direct connection of the container filled with the pumpable medium to the housing also has an advantageous effect on the seal between the container and the dispensing device, which is particularly necessary in the case of dimensionally stable containers in order to be able to suck in the medium.

In einer ersten bevorzugten Ausführung ist vorgesehen, dass der Bajonettverschluss einen Öffnungswiderstand aufweist. Auf diese Weise verrastet der Bajonettverschluss bei Erreichen des Anschlags und kann nicht zufällig selbständig öffnen, sondern muss bewusst unter Überwindung des Öffnungswiderstandes verdreht werden.In a first preferred embodiment it is provided that the bayonet lock has an opening resistance. In this way, the bayonet lock engages when the stop is reached and cannot accidentally open by itself, but must be turned deliberately while overcoming the opening resistance.

In einer weiteren bevorzugten Ausführung ist bevorzugt vorgesehen, dass der Behälter einen an den Gehäuseoberteil ankoppelbaren Hals aufweist, an dem die behälterseitigen Elemente des Bajonettverschlusses vorgesehen sind. Der Anschluss- bzw. Verbindungsbereich ist dadurch ins Innere des Gehäuseoberteiles versetzt und abgedeckt bzw. geschützt.In a further preferred embodiment it is preferably provided that the container has a neck which can be coupled to the upper part of the housing and on which the container-side elements of the bayonet lock are provided. The connection or connection area is thereby offset and covered or protected in the interior of the upper part of the housing.

Bevorzugt weisen die behälterseitigen Elemente des Bajonettverschlusses jeweils einen axialen anziehenden Steg mit einer am Anschlag endenden Mulde auf, deren Übergang zum Steg den Öffnungswiderstand bildet. Unter "axial anziehend" wird dabei verstanden, dass der sich in Umfangsrichtung erstreckende Steg zumindest am Beginn eine Schräge aufweist, sodass beim Schließen des Bajonettverschlusses der Gehäuseoberteil gegen den Behälterrand gepresst wird, wobei eine bevorzugt dazwischen angeordnete Dichtung komprimiert wird.The elements of the bayonet lock on the container side preferably each have an axially attractive web with a trough ending at the stop, the transition of which to the web forms the opening resistance. "Axially attractive" is understood to mean that the web extending in the circumferential direction has a bevel at least at the beginning, so that when the bayonet catch is closed, the upper housing part against the Container edge is pressed, wherein a seal preferably arranged between them is compressed.

Alternativ kann auch vorgesehen sein, dass vor dem Anschlag des Bajonettverschlusses am Behälterhals eine parallel zum Anschlag angeordnete Rippe ausgebildet ist, die den Öffnungswiderstand bildet. Die gehäuseseitigen Elemente sind bevorzugt als zylindrische Noppen ausgebildet.Alternatively, provision can also be made for a rib, which is arranged parallel to the stop and which forms the opening resistance, to be formed before the stop of the bayonet lock on the container neck. The elements on the housing side are preferably designed as cylindrical knobs.

Ein erfindungsgemäßes Set weist einen Spender für ein pumpfähiges Medium auf, von dem in Fig. 1 der Gehäuseoberteil 1 gezeigt ist, und mindestens einen vor allem als Nachfüllung vorgesehenen Behälter 5 auf, in dem das zu spendende Medium, beispielsweise Seife, Gel, Creme, Desinfektionsmittel etc. enthalten ist. Der Behälter 5 ist mittels eines Bajonettverschlusses 9 (Fig. 2, 3) mit dem Gehäuseoberteil 1 verbunden.A set according to the invention has a dispenser for a pumpable medium, of which in Fig. 1 the upper housing part 1 is shown, and at least one container 5, which is primarily intended as a refill and in which the medium to be dispensed, for example soap, gel, cream, disinfectant, etc. is contained. The container 5 is secured by means of a bayonet lock 9 ( Fig. 2 , 3 ) connected to the upper housing part 1.

Der Gehäuseoberteil 1 enthält eine Ausgabeeinrichtung 2 für das im Behälter 5 enthaltene Medium, die bei berührungsloser Betätigung beispielsweise eine sensorgesteuerte, motorisch betriebene Schlauchquetschpumpe oder dergleichen und bei händischer Betätigung beispielsweise eine Hubkolbenpumpe aufweist. Für das Verständnis der Erfindung ist dies aber von untergeordneter Bedeutung.The upper housing part 1 contains an output device 2 for the medium contained in the container 5, which has for example a sensor-controlled, motor-driven peristaltic pump or the like when operated without contact, and a reciprocating piston pump when operated manually. However, this is of subordinate importance for understanding the invention.

Die Ausgabeeinrichtung 2 weist ein Ansaugrohr 3 auf, das an der Unterseite des Gehäuseoberteiles 1 vorsteht und mit dem Inneren des Behälters 5 strömungs-verbunden ist. Der Behälter 5 umfasst einen zylindrischen Hals 6 mit einem Boden 16, in dem eine Ansaugöffnung 24 und ein Belüftungsventil 25, beispielsweise ein Entenschnabelventil, vorgesehen sind. Der Hals 6 ist in den Behälter 5 eingeklebt, eingeschweißt oder eingerastet.The dispensing device 2 has a suction pipe 3 which protrudes on the underside of the upper housing part 1 and is flow-connected to the interior of the container 5. The container 5 comprises a cylindrical neck 6 with a bottom 16, in which a suction opening 24 and a ventilation valve 25, for example a duck bill valve, are provided. The neck 6 is glued, welded or snapped into the container 5.

Die Ansaugöffnung 24 ist vor dem Gebrauch durch eine Membran 26 (Fig. 4) abgedichtet, die beim Ansetzen des Behälters 5 vom Ansaugrohr 3 durchstoßen wird (Fig. 2). Die Membran 26 ist in eine unterseitige Vertiefung des Bodens 16 eingeklebt, eingeschweißt oder mit dem Hals 6 als 2-Komponenten-Element gefertigt. An der Außenseite des Halses 6 sind behälterseitige Elemente des Bajonettverschlusses 9 ausgebildet. Hierzu gehört jeweils ein etwa in Umfangsrichtung sich bis zu einem Anschlag 14 erstreckender Steg 11, der zumindest eine Einführschräge aufweist und in eine am Anschlag 14 endende Mulde 13 übergeht.The suction opening 24 is closed by a membrane 26 ( Fig. 4 ), which is pierced by the suction pipe 3 when the container 5 is attached ( Fig. 2 ). The membrane 26 is glued, welded or manufactured with the neck 6 as a 2-component element in a depression on the underside of the base 16. On the outside of the neck 6, elements of the bayonet lock 9 on the container side are formed. This includes a web 11 extending approximately in the circumferential direction up to a stop 14, which has at least one insertion bevel and merges into a trough 13 ending at the stop 14.

Am Gehäuseoberteil 1 sind gehäuseseitige Elemente 17 des Bajonettverschlusses 9 vorgesehen, insbesondere zylindrische Noppen oder dergleichen. Beim Ansetzen des Behälters 5 an den Gehäuseoberteil 1 und anschließenden Verdrehen um die Längsachse gelangen die gehäuseseitigen Elemente 17 unter die Stege 11 und der Behälter 5 wird aufgrund der Einführschräge nach oben an den Gehäuseoberteil 1 gepresst.Housing-side elements 17 of the bayonet catch 9 are provided on the upper housing part 1, in particular cylindrical knobs or the like. When the container 5 is attached to the upper housing part 1 and then rotated about the longitudinal axis, the elements 17 on the housing side pass under the webs 11 and the container 5 is pressed upward against the upper housing part 1 due to the insertion bevel.

Um das versehentliche Öffnen des Bajonettverschlusses 9 zu vermeiden, ist ein Öffnungswiderstand ausgebildet, der beispielsweise durch den Übergang zwischen der Mulde 13 und dem Steg 11 und/oder durch eine parallel zum Anschlag 14 angeformte Rippe 15 erreicht wird. Das bedeutet, dass der Behälter 5 beim Verriegeln oder beim Öffnen des Bajonettverschlusses 9 ein Hindernis spürbar überwindet. Eine nicht gezeigte Verschlusskappe für den Behälter 5 weist den gehäuseseitigen Elementen 17 des Gehäuseoberteiles 1 gleiche Vorsprünge oder Noppen auf.In order to avoid inadvertent opening of the bayonet lock 9, an opening resistance is formed, which is achieved, for example, by the transition between the trough 13 and the web 11 and / or by a rib 15 formed parallel to the stop 14. This means that the container 5 noticeably overcomes an obstacle when locking or opening the bayonet lock 9.
