Description

Die Erfindung betrifft einen Spender mit einem Gehäuse für austauschbare Nachfüllungen fließfähiger Produkte, die kopfstehend in eine Aufnahme des Gehäuses eingesetzt werden können.The invention relates to a dispenser having a housing for interchangeable refills of flowable products which can be inserted upside down in a receptacle of the housing.

Solche Spender sind beispielsweise geeignet, Reinigungsmittel, Pflegemittel, Desinfektionsmittel oder dergleichen dosiert abzugeben. Als fließfähige Produkte kommen insbesondere Fluide, gegebenenfalls auch rieselfähige oder pastöse Medien in Frage.Such dispensers are suitable, for example, for dispensing cleaning agents, care products, disinfectants or the like in doses. In particular, fluids, optionally also free-flowing or pasty media, come into consideration as free-flowing products.

Ein Spendesystem mit einem derartigen Spender ist beispielsweise in der WO 2015/089531 des Anmelders beschrieben. Der Spender weist ein Gehäuse mit einer öffenbaren Abdeckung auf, in dessen unterem Bereich ein mit einer Einlassöffnung versehener Zwischenbehälter und eine das Produkt aus dem Zwischenbehälter abgebende Dosierpumpe angeordnet sind. An der Oberseite des Zwischenbehälters sind beidseitig der Einlassöffnung Führungselemente vorgesehen, die das Einschieben einer entsprechend ausgebildeten Nachfüllung gestatten. Die hierfür geeignete Nachfüllung weist ein Bodenelement auf, an dem ein mit einem Schiebeverschluss versehener Stutzen vorgesehen ist, der korrespondierende Schiebeführungselemente trägt. Eine Dichtung zwischen Stutzen und Schiebeverschluss verbleibt an der Nachfüllung und dichtet dessen Stutzen gegen den Zwischenbehälter des Spenders, während der Schiebeverschluss in einem ein Depot bildenden Raum vor der Einlassöffnung verbleibt. Die Nachfüllung wird also mit dem verschlossenen Stutzen nach unten gerichtet in den Spender eingesetzt, indem sie vor der Einlassöffnung des Zwischenbehälters platziert und dann in die Führungselemente eingeschoben wird, wobei der Schiebeverschluss den Stutzen der Nachfüllung freigibt. Bei Entnahme der leeren Nachfüllung oder Wechsel einer noch nicht geleerten Nachfüllung wird diese nach vorne gezogen, wobei sich der im Depot gehaltene Verschluss wieder auf den Stutzen der Nachfüllung dichtend aufschiebt.A donation system with such a donor is, for example, in WO 2015/089531 described by the applicant. The dispenser has a housing with an openable cover, in the lower area of which an intermediate container provided with an inlet opening and a dosing pump dispensing the product from the intermediate container are arranged. On the upper side of the intermediate container, guide elements are provided on both sides of the inlet opening, which allow a correspondingly designed refill to be pushed in. The refill that is suitable for this purpose has a base element on which a connecting piece is provided which is provided with a sliding closure and carries corresponding sliding guide elements. A seal between the spout and slide closure remains on the refill and seals its spout against the dispenser's surge tank, while the slide closure resides in a depot space in front of the inlet port. The refill is then inserted into the dispenser with the closed spout pointing downwards, placing it in front of the inlet opening of the surge tank and then sliding it into the guide elements, the sliding closure releasing the refill spout. When removing the empty refill or changing a refill that has not yet been emptied, it is pulled forwards, with the closure held in the depot being pushed back onto the socket of the refill to form a seal.

Die Nachfüllung weist bevorzugt eine Hülle aus einer dünnen Kunststofffolie auf, die etwa quaderförmig ist und an der das mit dem Stutzen versehene Bodenelement eine Versteifung bzw. Verstärkung bildet, die auch beim Einschieben der Nachfüllung in den Spender eine Handhabe oder Angriffsmöglichkeit für die Bedienungsperson darstellt.The refill preferably has a cover made of a thin plastic film, which is roughly cuboid and on which the base element provided with the socket forms a stiffening or reinforcement, which also represents a handle or possibility for the operator to grip when inserting the refill into the dispenser.

Die Stabilität der Handhabe lässt aber zu wünschen übrig, da ja beim Einschieben der Nachfüllung das Öffnen des Schiebeverschlusses durch die erhöhte Reibung des Dichtrings wesentlich erschwert wird.However, the stability of the handle leaves a lot to be desired, since the increased friction of the sealing ring makes it much more difficult to open the slide closure when the refill is pushed in.

Die Erfindung hat es sich daher zur Aufgabe gestellt, den Einsetz- und Entnahmevorgang zu erleichtern und erreicht dies durch die Merkmale des Anspruchs 1.The invention has therefore set itself the task of facilitating the insertion and removal process and achieves this through the features of claim 1.

Die Aufnahme ist bevorzugt in Art einer Schublade horizontal verschiebbar und die Nachfüllung lässt sich erleichtert in einer aus dem Gehäuse ausgeschobenen Be- bzw. Entladestellung einsetzen bzw. entnehmen und gemeinsam mit der Schublade mit erhöhter Stabilität in die Abgabestellung einschieben, in der die Einlassöffnung des Zwischenbehälters des Spenders mit der Öffnung im Stutzen der Nachfüllung fluchtet.The receptacle is preferably horizontally displaceable in the manner of a drawer and the refill can be inserted or removed more easily in a loading or unloading position pushed out of the housing and pushed together with the drawer with increased stability into the dispensing position in which the inlet opening of the intermediate container of the dispenser is aligned with the opening in the refill nozzle.

Die Aufnahme für die Nachfüllung ist dadurch gekennzeichnet, dass im Gehäuse relativ zu einer Ausgabeeinheit und relativ zum Gehäuse verschiebbar gelagert.The receptacle for the refill is characterized in that it is mounted in the housing so that it can be displaced relative to a dispensing unit and relative to the housing.

Da die Nachfüllung bevorzugt eine nur wenig formstabile Hülle des Produktes bildet, ist es in einer bevorzugten Ausführung von Vorteil, wenn die Aufnahme eine vordere und eine hintere Seitenwand zur Anlage an der kopfstehend eingesetzten Nachfüllung aufweist, die jeweils senkrecht zur Schieberichtung verläuft, die die Nachfüllung stabilisieren.Since the refill preferably forms a shell of the product that is only slightly dimensionally stable, it is advantageous in a preferred embodiment if the receptacle has a front and a rear side wall for contact with the refill inserted upside down, which in each case runs perpendicular to the sliding direction that the refill stabilize.

Zudem kann mindestens eine laterale Seitenwand zur Anlage an der kopfstehend eingesetzten Nachfüllung vorgesehen sein. Dabei erstreckt sich die mindestens eine laterale Seitenwand vorzugsweise nur über einen Teil der Seite der Aufnahme, sodass für die Nachfüllung seitlich ein beschränkter Ausweichraum gegeben ist.In addition, at least one lateral side wall can be provided to rest against the refill used upside down. In this case, the at least one lateral side wall preferably only extends over part of the side of the receptacle, so that there is limited lateral space for refilling.

Die Aufnahme mit der vorderen und hinteren Seitenwand und den gegebenenfalls vorhandenen lateralen Seitenwänden bilden insgesamt zusammen mit dem Boden der Aufnahme eine Art Wanne, in die die kopfstehende Nachfüllung lagesicher eingesetzt werden kann.The receptacle with the front and rear side walls and the lateral side walls that may be present form a type of trough together with the base of the receptacle, into which the upside-down refill can be securely inserted.

Die Nachfüllung besteht vorzugsweise aus einem vorzugsweise quaderförmigen Behälter mit Wänden, die von einer flexiblen Folie gebildet sind, wobei auf einer der Quaderseiten eine feste Fläche aus Kunststoff vorgesehen ist. Diese feste Fläche liegt bei kopfstehender Nachfüllung am Boden der Aufnahme an. Sie enthält auch die Ausgabeöffnung für das fließfähige Produkt.The refill preferably consists of a preferably parallelepiped-shaped container with walls formed by a flexible foil, with a solid surface made of plastic being provided on one of the parallelepiped sides. This solid surface rests against the bottom of the receptacle when refilled upside down. It also contains the dispensing orifice for the flowable product.

In einer weiteren bevorzugten Ausführung ist vorgesehen, dass die Aufnahme einen Boden aufweist, an dem unterseitige Eingriffselemente in Schieberichtung angeordnet sind, die in Gegenelemente des Gehäuses eingreifen, wobei die Eingriffselemente und die Gegenelemente insbesondere eine Gleitführung bilden. Die Be- und Entladestellung sowie die Abgabestellung sind dabei vorzugsweise durch je einen Endanschlag der Gleitführung festgelegt.In a further preferred embodiment, it is provided that the receptacle has a base on which engaging elements are arranged on the underside in the sliding direction, which engage in counter-elements of the housing, with the engagement elements and the counter-elements in particular forming a sliding guide. The loading and unloading position and the delivery position are preferably defined by a respective end stop of the sliding guide.

Im eingangs genannten Spendersystem nach der WO 2015/089531 sind auch mehrere Möglichkeiten einer Codierung zwischen dem Spender und den Nachfüllungen vorgesehen, sodass also in einen Spender nur geeignete Nachfüllungen eingesetzt werden können. Die Codierung erfolgt durch Codierelemente, die einerseits am Spender und andererseits an den Nachfüllungen in unterschiedlichen Varianten ausgebildet sein können. So kann beispielsweise der Schiebeverschluss mit außeren Ausnehmungen und Vorsprüngen versehen sein, die mit Gegenelementen im Bereich des Depots zusammenwirken. Weiters können Freistellungen oder Vorsprünge an der Nachfüllung oder ihrem Stutzen mit Gegenelementen in der Umgebung der Einlassöffnung zusammenwirken, bzw. auch Querschnitte der Führungselemente zum Einschieben der Nachfüllung aufeinander abgestimmt sein.In the aforementioned donor system after WO 2015/089531 several possibilities for coding between the dispenser and the refills are also provided, so that only suitable refills can be used in a dispenser. The coding is done by coding elements, which can be formed in different variants on the one hand on the dispenser and on the other hand on the refills. For example, the sliding closure can be provided with external recesses and projections that interact with counter-elements in the area of the depot. Furthermore, waivers or projections on the Refill or their socket interact with counter-elements in the vicinity of the inlet opening, or be coordinated with each other for inserting the refill cross-sections of the guide elements.

Codierungen können daher auch erfindungsgemäß ausgebildet sein, indem Codierelemente an der verschiebbaren Aufnahme vorgesehen werden, die zu Gegenelementen an der Nachfüllung passen. In einer ersten bevorzugten Ausführung ist beispielsweise vorgesehen, dass die verschiebbare Aufnahme einen etwa rechteckigen Boden aufweist, und ein Codierelement als in zumindest einem Eckbereich des Bodens hochstehendes Element, insbesondere als Säule, ausgebildet ist. Weist eine Nachfüllung keine dem hochstehenden Element entsprechende Ausnehmung an ihrem Boden auf, kann sie nicht in die Aufnahme eingesetzt werden. Bevorzugt sind in jedem Eckbereich hochstehende Elemente vorgesehen, die runde oder eckige Querschnitte aufweisen können.Codes can therefore also be designed according to the invention in that coding elements are provided on the displaceable receptacle, which match counter-elements on the refill. In a first preferred embodiment, it is provided, for example, that the displaceable receptacle has an approximately rectangular base, and a coding element is designed as an element standing up in at least one corner region of the base, in particular as a column. If a refill does not have a recess in its bottom corresponding to the upstanding element, it cannot be inserted into the socket. Upstanding elements, which can have round or angular cross sections, are preferably provided in each corner area.

Wie bereits mehrfach erwähnt, ist die Ausstattung der Nachfüllungen mit einem Stutzen und einem Schiebeverschluss besonders vorteilhaft. Die verschiebbare Aufnahme ist aber auch mit Nachfüllungen bestückbar, die in anderer Weise verschlossen sind, beispielsweise könnte die Nachfüllung mit einem Verschluss versehen sein, der in der Abgabestellung mittels eines Dornes vom Spender aus durchstoßen wird. Die Nachfüllung könnte auch ein Ventil enthalten, das in der Abgabestellung hochgedrückt wird und bei Entnahme der Nachfüllung wieder schließt.As already mentioned several times, equipping the refills with a nozzle and a slide closure is particularly advantageous. However, the displaceable receptacle can also be fitted with refills that are closed in some other way; for example, the refill could be provided with a closure that is pierced in the dispensing position by a spike from the dispenser. The refill could also include a valve that is pushed up in the dispensing position and closes again when the refill is removed.

Für Nachfüllungen mit Stutzen und Schiebeverschluss ist in einer weiteren, bevorzugten Ausführung vorgesehen, dass ein Codierelement in Form einer mittigen Öffnung im Boden der verschiebbaren Aufnahme für den Durchtritt des verschlossenen Stutzens der Nachfüllung ausgebildet ist. Beim Einsetzen der Nachfüllung muss daher der Querschnitt des verschlossenen Stutzens der Öffnung im Boden entsprechen, damit die Nachfüllung in die verschiebbare Aufnahme eingesetzt werden kann, wobei der verschlossene Stutzen durch dieFor refills with a nozzle and a sliding closure, a further preferred embodiment provides for a coding element to be designed in the form of a central opening in the base of the displaceable receptacle for the closed nozzle of the refill to pass through. Therefore, when inserting the refill, the cross-section of the closed nozzle must correspond to the opening in the bottom, so that the refill can be inserted into the sliding seat, the closed nozzle passing through the

Öffnung im Boden nach unten ragt. Nur dann kann die Aufnahme in die Abgabestellung verschoben werden.opening in the floor protrudes downwards. Only then can the recording be moved to the delivery position.

Bevorzugt liegt die Öffnung in der Be- und Entladestellung der schiebbaren Aufnahme oberhalb des Depots für den Schiebeverschluss des Stutzens, sodass beim Einsetzen der richtig codierten Nachfüllung der Stutzen durch die Öffnung und der Schiebeverschluss in das Depot gelangen. Wird diese Endstellung erreicht, kann die verschiebbare Aufnahme in die Abgabestellung verschoben werden, wobei der Schiebeverschluss im Depot zurück gehalten wird und der geöffnete Stutzen der Nachfüllung mit der Einlassöffnung des Zwischenbehälters des Spenders fluchtet.In the loading and unloading position of the sliding receptacle, the opening is preferably above the depot for the sliding closure of the nozzle, so that when the correctly coded refill is inserted, the nozzle passes through the opening and the sliding closure into the depot. When this end position is reached, the displaceable receptacle can be moved into the dispensing position, with the sliding closure being held back in the depot and the opened nozzle of the refill being aligned with the inlet opening of the intermediate container of the dispenser.

In einer weiteren Ausführung kann dabei noch vorgesehen sein, dass das Gehäuse eine öffenbare, vorzugsweise schwenkbare Abdeckung aufweist, und die verschiebbare Aufnahme für die Nachfüllung mit dem Öffnen und Schließen der Abdeckung bewegungsgekoppelt ist.In a further embodiment, it can also be provided that the housing has an openable, preferably pivotable cover, and the displaceable receptacle for the refill is movement-coupled to the opening and closing of the cover.

Bevorzugt weist die Ausgabeeinheit eine Fördereinrichtung, vorzugsweise Dosierpumpe, zum Fördern eines fließfähigen Produktes aus der Nachfüllung zu einer Abgabestelle auf. Damit kann ein fließfähiges Produkt durch Betätigen der Fördereinrichtung abgegeben werden.The dispensing unit preferably has a conveying device, preferably a dosing pump, for conveying a free-flowing product from the refill to a delivery point. A free-flowing product can thus be dispensed by actuating the conveying device.

Nachstehend wird nun die Erfindung anhand der Figuren der beiliegenden Zeichnungen näher beschrieben, ohne darauf beschränkt zu sein. Es zeigen:

Eine Nachfüllung 20 aus weichem flexiblem Material, beispielsweise aus dünner Kunststofffolie, ist etwa quaderförmig und weist ein insbesondere mit einer Verstärkung versehenen Boden einen Stutzen 21 mit einer Öffnung auf. Die Verstärkung erstreckt sich über die Fläche des Bodens und umgreift zwei gegenüberliegende Kanten. Details über eine derartige Nachfüllung und deren Herstellung sind etwa der WO 2008/089500 zu entnehmen.A refill 20 made of soft, flexible material, for example a thin plastic film, is approximately cuboid and has a socket 21 with an opening on a base provided in particular with a reinforcement. The reinforcement extends across the face of the floor and embraces two opposite edges. Details about such a refill and its production are about WO 2008/089500 refer to.

Die Nachfüllung enthält insbesondere ein flüssiges Produkt wie Seife, Shampoo oder Desinfektionsmittel und wird kopfstehend in das Gehäuse 1 eines Spenders eingesetzt. Der Stutzen 21 trägt beidseitig abstehende Stege in Verlängerung seiner Stirnfläche und einen aus der Stirnfläche geringfügig vorstehenden Dichtungsring. Als Verschluss 22 dient ein etwa klammer- bzw. C-förmiger Körper, der von der Seite aufgeschoben wird, wobei er die Stege hintergreift.In particular, the refill contains a liquid product such as soap, shampoo or disinfectant and is inserted upside down into the housing 1 of a dispenser. The connecting piece 21 carries protruding webs on both sides as an extension of its end face and a sealing ring protruding slightly from the end face. An approximately clamp- or C-shaped body serves as the closure 22 and is pushed on from the side, engaging behind the webs.

Die Nachfüllungen 20 werden kopfstehend in einen Spender eingesetzt, der ein Gehäuse 1 mit einer öffenbaren, vorderen Abdeckung 2 versehen ist. Die Abdeckung 2, der in Fig. 1 nur einen oberen Bereich angedeutet ist, ist insbesondere verschwenkbar angeordnet, sodass sie nach oben oder unten geklappt werden kann. Der in Fig. 1 dargestellte Spender weist im Unterteil eine Ausgabeeinheit 13 für das fließfähige Produkt auf. Die Ausgabeeinheit 13 kann beispielsweise eine Fördereinrichtung 16, vorzugsweise eine Dosierpumpe, zum Fördern des fließfähigen Produktes aus der Nachfüllung 20 (Fig. 4) zu einer Abgabestelle 14 (Fig. 1) aufweisen. Zwischen der Nachfüllung 20 und der Abgabestelle 14 kann das fließfähige Produkt temporär in einem Zwischenbehälter 17 aufbewahrt werden. An der Oberseite des Zwischenbehälters 17 ist ein Anschlusselement 9 mit einer Öffnung vorgesehen, an das die Nachfüllung 20 angedockt werden kann. Da die Nachfüllung 20 durch einen Schiebeverschluss 22 verschlossen ist, erfolgt dies durch Verschieben der Nachfüllung 20, d. h. durch Einschieben des Stutzens 21 in das Anschlusselement 9, wobei der Schiebeverschluss 22 abgestreift wird und in einer vor dem Anschlusselement 9 vorgesehenen Vertiefung, die nachfolgend Depot 23 genannt wird, liegen bleibt, wie aus den Figuren 1 bis 3 ersichtlich ist.The refills 20 are placed upside down in a dispenser having a housing 1 with an openable front cover 2 . The cover 2, the in 1 only an upper area is indicated, is in particular arranged pivotably, so that it can be folded up or down. the inside 1 The dispenser shown has a dispensing unit 13 for the free-flowing product in the lower part. The dispensing unit 13 can, for example, be a conveying device 16, preferably a dosing pump, for conveying the free-flowing product from the refill 20 ( 4 ) to a delivery point 14 ( 1 ) exhibit. The free-flowing product can be temporarily stored in an intermediate container 17 between the refill 20 and the delivery point 14 . At the top of Intermediate container 17 is a connection element 9 is provided with an opening to which the refill 20 can be docked. Since the refill 20 is closed by a sliding closure 22, this is done by sliding the refill 20, i.e. by pushing the socket 21 into the connection element 9, with the sliding closure 22 being stripped off and in a recess provided in front of the connection element 9, which is subsequently called depot 23 is called, remains, as from the Figures 1 to 3 is evident.

Das Depot 23 ist durch Stege begrenzt, sodass es den Verschluss 22 formschlüssig aufnimmt. Dadurch schiebt sich die Nachfüllung 20 bei der Entnahme wieder auf den Verschluss auf und kann wiederverschlossen aus dem Spender entfernt werden. Die Nachfüllung 20 kann daher auch noch teilgefüllt getauscht werden, ohne dass eine Teilmenge verloren geht.The depot 23 is delimited by webs so that it receives the closure 22 in a form-fitting manner. As a result, the refill 20 slides back onto the closure when it is removed and can be removed from the dispenser after it has been closed again. The refill 20 can therefore also be exchanged when it is partially filled, without a portion being lost.

Das Einschieben einer gefüllten Nachfüllung 20 in das Anschlusselement 9 bedarf eines bestimmten Kraftaufwandes, da der ober erwähnte Dichtungsring, der den Schiebeverschluss 22 dichtet, mit in das Anschlusselement 9 eingeschoben wird und dort die Abdichtung zum Anschlusselement 9 bewirkt. Insbesondere wenn die Nachfüllung 20 aus einem flexiblen Material besteht, wird sie beim Einschieben in den Spender nur durch die Verstärkung des Bodens stabilisiert.Pushing a filled refill 20 into the connection element 9 requires a certain amount of force, since the above-mentioned sealing ring, which seals the sliding closure 22, is also pushed into the connection element 9 and causes the seal to the connection element 9 there. In particular, when the refill 20 is made of a flexible material, it is only stabilized by the reinforcement of the bottom when inserted into the dispenser.

Um nun die Handhabung der Nachfüllung 20 zu erleichtern, ist im Gehäuse 1 eine in der Art einer Schublade verschiebbare Aufnahme 3 für die Nachfüllung vorgesehen.In order to facilitate the handling of the refill 20, a receptacle 3 for the refill that can be moved in the manner of a drawer is provided in the housing 1.

Die Aufnahme 3 weist einen Boden 5 mit einer Öffnung 8 und eine vordere und eine hintere Seitenwand 4 zur Anlage der kopfstehend eingesetzten Nachfüllung 20 auf. Zudem weist die Aufnahme 3 zwei laterale Seitenwände 15 zur Anlage an der kopfstehend eingesetzten Nachfüllung 20 auf, wobei sich die laterale Seitenwände 15 nur über einen Teil der Seite der Aufnahme 3 erstrecken. Links und rechts ist die Aufnahme 3 weitgehend offen. Die Figuren 4 bis 6 zeigen die Aufnahme 3 jeweils in Schrägansicht von oben, wobei Fig. 4 die herausgezogene Be- bzw. Entladestellung und Fig. 5 die eingeschobene Abgabestellung darstellt. In der Be- und Entladestellung nach Fig. 2 und Fig. 4 wird die verschlossene, kopfstehende Nachfüllung von oben in die Aufnahme 3 eingesetzt. Der verschlossene Stutzen 21 ragt dann durch die Öffnung 8 im Boden 5 der Aufnahme 3 nach unten, wobei der Schiebeverschluss 22 in das unmittelbar unter der Öffnung 8 vorgesehene Depot 23 eingreift. Die Aufnahme 3 wird anschließend in Richtung des Pfeiles A in die Abgabestellung (Fig. 3, 5) verschoben, wobei der Stutzen 21 vom Schiebeverschluss 22 befreit und in das Anschlusselement 9 eingeschoben wird. Der Schiebeweg ist durch einen Anschlag 12 (Fig. 2, 3) begrenzt. Der Schiebeverschluss 22 bleibt im Depot 23 liegen, bis die vollständig oder auch nur teilweise entleerte Nachfüllung 20 wieder aus dem Spender herausgenommen wird, wobei die Aufnahme 3 in Richtung des Pfeiles B wieder in die Be- und Entladestellung verschoben wird. Dabei schiebt sich der Schiebeverschluss 22 wieder auf den Stutzen 21 auf und die Nachfüllung kann - dicht verschlossen - wieder nach oben entnommen werden. Ein nicht näher gezeigter Anschlag legt auch die Be- und Entladestellung der verschiebbaren Aufnahme 3 fest.The receptacle 3 has a bottom 5 with an opening 8 and a front and a rear side wall 4 for resting the refill 20 inserted upside down. In addition, the receptacle 3 has two lateral side walls 15 for resting against the refill 20 inserted upside down, the lateral side walls 15 only extending over part of the side of the receptacle 3 . Recording 3 is largely open on the left and right. the Figures 4 to 6 show the Recording 3 each in an oblique view from above, where 4 the pulled-out loading or unloading position and figure 5 represents the inserted delivery position. In the loading and unloading position 2 and 4 the closed, upside-down refill is inserted into receptacle 3 from above. The closed socket 21 then protrudes downwards through the opening 8 in the bottom 5 of the receptacle 3 , with the sliding closure 22 engaging in the depot 23 provided directly below the opening 8 . The receptacle 3 is then moved in the direction of arrow A to the delivery position ( 3 , 5 ) shifted, the socket 21 being freed from the sliding closure 22 and pushed into the connection element 9 . The sliding path is defined by a stop 12 ( 2 , 3 ) limited. The sliding closure 22 remains in the depot 23 until the completely or only partially emptied refill 20 is removed from the dispenser again, with the receptacle 3 being moved in the direction of arrow B back into the loading and unloading position. The sliding closure 22 is then pushed back onto the socket 21 and the refill can be removed upwards again - tightly closed. A stop, not shown in detail, also defines the loading and unloading position of the displaceable receptacle 3 .

Zwischen der Unterseite der verschiebbaren Aufnahme 3 und dem Anschlusselement 9 im Gehäuse 1 des Spenders ist eine Gleitführung ausgebildet, die unterseitige Eingriffselemente 6 und Gegenelemente 11 umfasst. Diese sind in den Figuren 4 bis 6 in Form von ineinander greifenden abgewinkelten Stegen gezeigt, die sich in Schieberichtung A, B erstrecken.A sliding guide is formed between the underside of the displaceable receptacle 3 and the connection element 9 in the housing 1 of the dispenser, which includes engagement elements 6 and counter-elements 11 on the underside. These are in the Figures 4 to 6 shown in the form of interlocking angled webs extending in the sliding direction A, B.

Um nun sicher zu stellen, dass in den Spender nur geeignete Nachfüllungen 20 eingesetzt werden können, ist eine Codierung vorgesehen, d. h., an jeder Nachfüllung 20 und am Spender müssen ineinander passende Elemente ausgebildet sein. Hierfür kann, wie vor allem aus den Figuren 4 bis 6 ersichtlich, eine besondere Querschnittsform der Öffnung 8, beispielsweise rechteckig (mit eventuellen zusätzlichen, einander gegenüber liegenden Ausbuchtungen) vorgesehen sein, die auf die Außenkontur des rechteckigen Schiebeverschlusses abgestimmt ist. Es können aber auch oder zusätzlich, wie in Fig. 6 gezeigt, vom Boden 5 der verschiebbaren Aufnahme 3 in den Eckbereichen hochstehende Elemente 7, wie Säulen in Kegelstumpf- oder Quaderform, ausgebildet sein, zu denen an der Verstärkung des Bodens 19 der Nachfüllung 20 passende Ausnehmungen vorgesehen sind.In order to ensure that only suitable refills 20 can be used in the dispenser, coding is provided, ie elements that fit into one another must be formed on each refill 20 and on the dispenser. For this, as mainly from the Figures 4 to 6 As can be seen, a particular cross-sectional shape of the opening 8, for example rectangular (with possible additional, opposite bulges) can be provided, which on the outer contour of the rectangular Sliding closure is matched. However, it can also or additionally, as in 6 shown, from the bottom 5 of the slidable receptacle 3 in the corner areas upstanding elements 7, such as columns in the shape of a truncated cone or cuboid, may be formed, for which matching recesses are provided on the reinforcement of the bottom 19 of the refill 20.

Die Bewegung der verschiebbaren Aufnahme 3 zwischen der Be- und Entladestellung (Fig. 2, 4) und der Abgabestellung (Fig. 3, 5) kann wie beschrieben per Hand erfolgen. Es ist aber auch möglich, zwischen der Abdeckung 2 des Gehäuses 1 und der Aufnahme 3 ein nicht gezeigtes Kuppelelement auszubilden, sodass das Öffnen der Abdeckung 2, vor allem nach unten, die Aufnahme 3 herauszieht und der Nachfüllung 20 in das Anschlusselement 9 einschiebt.The movement of the movable receptacle 3 between the loading and unloading position ( 2 , 4 ) and the delivery position ( 3 , 5 ) can be done manually as described. However, it is also possible to form a coupling element (not shown) between the cover 2 of the housing 1 and the receptacle 3, so that opening the cover 2, especially downwards, pulls out the receptacle 3 and pushes the refill 20 into the connection element 9.
