Abstract

A device for filling an ink cartridge, particularly a refilling device for filling ink cartridges of ink-jet systems, such as printers and plotters, or other automatic registering, writing or drawing apparatus, includes a refilling container and an ink cartridge connected through an adaptor and arranged essentially one above the other in the filling position. The adaptor has at least two connections for the refilling container and the cartridge to be connected. A separate ink reservoir is arranged in the ink cartridge, wherein the ink reservoir of the ink cartridge and/or the filling container of the refilling container includes an easily deformable bag, and wherein the reservoir bag and/or container bag are of a flexible, elastic material. A hermetically sealed cartridge space is formed between the cartridge housing and the separate ink reservoir. The adaptor is constructed and dimensioned in such a way, that, together with the ink cartridge and the refilling container, the adaptor forms in the filling position a hermetically closed filling system and an additional air system between the hermetically sealed cartridge space and the atmosphere.

Description

Die Erfindung betrifft eine Vorrichtung zum Befüllen eines Tintentanks, insbesondere eine Nachfüll-Vorrichtung zum Befüllen von Tintentanks für Ink-Jet-Systeme, wie Drucker und Plotter, oder sonstige automatische Registrier-, Schreib- oder Zeichenanlagen.The invention relates to a device for filling a Ink tanks, in particular a refill device for Filling ink tanks for ink jet systems, such as printers and plotter, or other automatic registration, Writing or drawing systems.

Nachfüll-Vorrichtungen zum Befüllen von Behältern bzw. von Tintentanks sind prinzipiell bekannt.
So gibt es zum Beispiel Nachfüllsysteme, zum Befüllen von Tintentanks für Ink-Jet-Systeme und Plotter oder für sonstige automatische Registrier-, Schreib- oder Zeichenanlagen, mit deren Hilfe es möglich ist, die leer geschriebenen Tintentanks der Druckköpfe oder der Aufzeichnungsstifte wieder mit neuer Tinte oder sonstigem Aufzeichnungsmittel nachzufüllen.Refill devices for filling containers or ink tanks are known in principle.
There are, for example, refill systems, for filling ink tanks for ink-jet systems and plotters or for other automatic registration, writing or drawing systems, with the help of which it is possible to replace the empty ink tanks of the printheads or recording pens with new ones Refill ink or other recording media.

Aus [1] US-PS 5 595 223 ist eine Tinten-Nachfüll-Vorrichtung bekannt bei der ein Adapter vorgesehen ist, der auf einem Druckkopf angeordnet wird und mit dessen Hilfe einerseits der Tintentank des Druckkopfes geöffnet und zudem ein Nachfüllbehälter aufgesetzt, angestochen und befestigt werden kann. Beim Öffnen oder Anstechen der Behälter werden die Verschlussteile gelöst oder zerstört, so dass dann die Tinte von dem Behälter in den Tank fließen kann.
Der Luftausgleich in dem zu befüllenden Tank und über diesen im Nachfüllbehälter, erfolgt hierbei über Luftkanäle, die ins Freie münden. Zur Befüllung des Tanks muss der Nachfüllbehälter oberhalb bzw. über dem Adapter angeordnet sein, damit die Tinte durch Schwerkraft selbsttätig aus dem Behälter in den Tank fließen kann.
Nachteilig bei einer derartigen Vorrichtung in Form dieses Adapters ist es, dass mit dem Adapter kein hermetisch abgeriegelter Tank, bzw. kein Tank ohne permanent geöffneten Luftausgleich, aufgrund des sich aufbauenden Gegendrucks, nachgefüllt werden kann. From [1] US Pat. No. 5,595,223 an ink refill device is known in which an adapter is provided which is arranged on a print head and with the help of which on the one hand the ink tank of the print head is opened and also a refill container is placed, pierced and fastened can be. When the container is opened or punctured, the closure parts are loosened or destroyed, so that the ink can then flow from the container into the tank.
The air equalization in the tank to be filled and via this in the refill container takes place via air channels that open into the open. To fill the tank, the refill container must be arranged above or above the adapter so that the ink can flow automatically from the container into the tank due to gravity.
A disadvantage of such a device in the form of this adapter is that the adapter cannot be used to refill a hermetically sealed tank or a tank without permanently open air equalization due to the counter pressure building up.

Weiter sind aus [2] DE 199 12 620 A1 Vorrichtungen und Anordnungen bekannt, bei denen Nachfüllbehälter mit einem Tintentank durch einen Adapter verbunden werden und in Füllposition im wesentlichen übereinander angeordnet sind. Der Füllvorgang erfolgt hierbei durch Schwerkraft, da sich der ggf. vorhandene Tintenbeutel im Tintentank ungehindert entfalten kann, sobald Tinte in diesen einfließt. Nachteilig ist es hierbei, dass ein Nachfüllen des Tintentanks nur dann möglich ist und funktioniert, solange kein Gegendruck im Tintentank des niedrigeren Niveaus vorherrscht oder sich aufbaut.
Ein Gegendruck beispielsweise würde dann vorliegen oder aufgebaut, wenn der dort gezeigte Tintenbeutel von einem zur Umgebung hermetisch abgeschlossenen Gehäuse umgeben wäre. Dann wäre ein Nachfüllen des Tintenspeichers mit der beschriebenen Vorrichtung aufgrund des entstehenden Überdrucks auch mit Hilfsmitteln wie Pumpen nicht möglich. Bei einer anderen dort gezeigten Lösung erfolgt lediglich ein interner Druckausgleich zwischen zwei unflexiblen und starr miteinander verbundenen Tintentanks über einfache Luftdurchlässe.Devices and arrangements are also known from [2] DE 199 12 620 A1 , in which refill containers are connected to an ink tank by an adapter and are arranged essentially one above the other in the filling position. The filling process is carried out by gravity, since the ink bag in the ink tank, if present, can unfold as soon as ink flows into it. The disadvantage here is that refilling the ink tank is only possible and works as long as there is no back pressure in the ink tank of the lower level or builds up.
A counterpressure, for example, would exist or build up if the ink bag shown there were surrounded by a housing that was hermetically sealed from the surroundings. Then it would not be possible to refill the ink reservoir with the described device due to the resulting excess pressure, even with aids such as pumps. In another solution shown there, only an internal pressure equalization takes place between two inflexible and rigidly connected ink tanks via simple air outlets.

Aufgabe der Erfindung ist es demgegenüber, eine Vorrichtung zum Nachfüllen von Tintentanks zu schaffen, die die oben erwähnten Nachteile nicht aufweist und die dem Benutzer eine preiswerte, einfache und saubere Möglichkeit bietet, schwer nachfüllbare Tanks, wie z.B. hermetisch abgeschlossene Tanksysteme nachzufüllen.
Hierdurch wird das vorhandene Material, wie leer geschriebene Tanks, mit oder ohne Druckköpfen, nochmals weiter verwendbar, was zur Schonung von Ressourcen, durch reduzierten Abfall führt und andererseits dem Benutzer ggf. Kosten spart. In contrast, the object of the invention is to provide a device for refilling ink tanks which does not have the disadvantages mentioned above and which offers the user an inexpensive, simple and clean possibility of refilling tanks which are difficult to refill, such as hermetically sealed tank systems.
As a result, the existing material, such as empty tanks, with or without printheads, can be used again, which saves resources, reduces waste and, on the other hand, saves costs for the user.

Die Lösung dieser Aufgabe erfolgt bei einer Vorrichtung zum Befüllen eines Tintentanks, mit den im Anspruch 1 umfassten Merkmalen.
Vorteilhafte Weiterbildungen und Ausgestaltungen sind in den weiteren Ansprüchen erfasst. The solution of this object is achieved in an apparatus for filling an ink cartridge with the encompassed in claim 1.
Advantageous further developments and refinements are covered in the further claims.

In Figur 1 ist der prinzipielle Aufbau einer vorschlagsgemäßen Vorrichtung dargestellt, wobei in einen Adapter 1 ein nachzufüllender Tintentank 2 und ein, den Tintenvorrat enthaltender, Nachfüllbehälter 3 eingesetzt sind. FIG. 1 shows the basic structure of a proposed device, an ink tank 2 to be refilled and a refill container 3 containing the ink supply being inserted into an adapter 1.

In der Figur 2 ist der Adapter 1 als separates Teil von vorne, bzw. von der Seite gezeigt, an die der hier nicht dargestellte Tintentank (2) angeschlossen wird. Am Verteilergehäuse 11 des Adapters 1 ist ein Tankanschluss 12 als Steckverbindung angeordnet. Der Tankanschluss 12 besteht aus einem Anschlusskörper 121, sowie einem Füllanschluss 123, mit einer Tankkanüle 142 und einem Luftanschluss 124, mit einer Luftkanüle 151. Ein hier nicht gezeigter Nachfüllbehälter (3) kann im Anschlussgehäuse 131 am Behälteranschluss 13 eingeschoben werden. Seitlich am Anschlussgehäuse 131 sind Führungsnuten 132 angebracht, in die Zentriernasen oder Nocken des Nachfüllbehälters (3) eingreifen können, z.B. zur Identifikation der Zusammengehörigkeit definierter Befüllsysteme. Wenn der Adapter jeweils für einen ganz bestimmten Tinten- oder Gerätetyp geeignet sein soll, sind Form und Lage der Anordnungen ggf. verschieden auszuführen. In FIG. 2 , the adapter 1 is shown as a separate part from the front or from the side to which the ink tank (2), not shown here, is connected. A tank connection 12 is arranged as a plug connection on the distributor housing 11 of the adapter 1. The tank connection 12 consists of a connection body 121, as well as a filling connection 123, with a tank cannula 142 and an air connection 124, with an air cannula 151. A refill container (3), not shown here, can be inserted into the connection housing 131 at the container connection 13. Guide grooves 132 are provided on the side of the connection housing 131, into which centering lugs or cams of the refill container (3) can engage, for example for identifying the togetherness of defined filling systems. If the adapter is to be suitable for a specific ink or device type, the shape and position of the arrangements may have to be designed differently.

In Figur 3 ist die Füllsituation dargestellt, wobei in bzw. an das Verteilergehäuse 11 des Adapters 1 ein Nachfüllbehälter 3 eingesetzt und ein Tintentank 2 aufgeschoben ist.
Das Tankmundstück 23 des Tintentanks 2 ist auf den Tankanschluss 12 des Adapters 1 aufgesetzt und mit dessen Füllanschluss 123 reibschlüssig verbunden.
Die Reservetinte fließt als Nachfüllmittel 300 über das Füllsystem 14, bzw. über die Behälterkanüle 143, den Füllkanal 141 und die Tankkanüle 142 in das Tankreservoir 22 des Tintentanks 2, als von dort aus wieder verwendbares Schreibmittel 200. In den Füllkanal 141 sind tankseitig die Tankkanüle 142 und behälterseitig die Behälterkanüle 143 fest eingesetzt, die mittels Anstechspitzen oder Druckschrägen die Tankdichtung 212 im Tankmundstück 23 und die Behälterdichtung 322 in der Behälterhülle 321 durchdringen und somit den durchgehenden Tintenfluss ermöglichen.
Innerhalb des Tankgehäuses 21, im hermetisch abgeschlossenen Tankraum 211, liegt der Tintenspeicher 22, begrenzt durch die Speicherhülle 221. Damit beim Nachfüllvorgang der im Behältergehäuse 31 von der Behälterhülle 321 begrenzte weiche Füllbehälter 32 beim Entleeren ungehindert in sich zusammenfallen kann, sind im Behältergehäuse 31 mindestens eine Behälteröffnung 312 zur Belüftung des Behälterraumes 311 angeordnet.In Figure 3, the filling situation is depicted in which a refill container 3 is inserted in or on the distributor housing 11 of the adapter 1 and an ink tank 2 is pushed.
The tank mouthpiece 23 of the ink tank 2 is placed on the tank connection 12 of the adapter 1 and connected to its filling connection 123 in a friction-locked manner.
The reserve ink flows as refill means 300 via the fill system 14, or via the container cannula 143, the fill channel 141 and the tank cannula 142 into the tank reservoir 22 of the ink tank 2, as reusable writing means 200 from there. The tank cannulas are in the fill channel 141 142 and on the container side, the container cannula 143 is firmly inserted, which penetrate the tank seal 212 in the tank mouthpiece 23 and the container seal 322 in the container sleeve 321 by means of piercing tips or pressure bevels and thus enable the continuous ink flow.
Inside the tank housing 21, in the hermetically sealed tank chamber 211, is the ink reservoir 22, delimited by the storage sleeve 221. So that during the refilling process the soft filling container 32 delimited by the container sleeve 321 in the container housing 31 can collapse unhindered when emptied, there are at least in the container housing 31 a container opening 312 for ventilation of the container space 311 is arranged.

Figur 4 zeigt die Vorrichtung gem. Figur 3, mit dem Adapter 1, dem Tintentank 2 und dem Nachfüllbehälter 3, wobei hier ein Schnitt durch das Belüftungssystem 15 gelegt ist, gemäß Linie B-B in Figur 2. Das im Verteilergehäuse 11 integrierte Belüftungssystem 15 weist hier zum Tintentank 2 hin eine fest eingesetzte Luftkanüle 151 auf und stellt über eine Luftöffnung 152 freien Durchgang zur Umgebung her. Dadurch entsteht Druckausgleich zur Atmosphäre und es entweicht beim Füllvorgang genau so viel Luft aus dem sonst hermetisch abgeschlossenen Tankraum 211 des Tintentanks 2, wie die nachgefüllte Menge des Nachfüllmittels 300 aus dem Füllbehälter 32 als neu verfügbares Schreibmittel 200 an Volumen im Tintenspeicher 22 einnimmt. Die Luftkanüle 151 durchdringt mit ihrer Anstechspitze beim Anschließen die im Luftmundstück 24 fest angeordnete Luftdichtung 213 und öffnet damit den sonst hermetisch abgeschlossenen Tankraum 211 im Tintentank 2. Während der Tintentank 2 über den Tankanschluss 12 mit dem Verteilergehäuse 11 des Adapters 1 reibschlüssig aber lösbar verbunden ist, befindet sich das Behältergehäuse 31 des Nachfüllbehälters 3, abgedichtet aber relativ lose sitzend, im Anschlussgehäuse 131 des Behälteranschlusses 13. Figure 4 shows the device acc. Figure 3, with the adapter 1, the ink tank 2 and the refill container 3, here a section through the ventilation system 15 is made, according to line BB in Figure 2. The ventilation system 15 integrated in the distributor housing 11 has a firmly inserted towards the ink tank 2 here Air cannula 151 and creates a free passage to the environment via an air opening 152. This creates pressure equalization to the atmosphere, and during the filling process, as much air escapes from the otherwise hermetically sealed tank space 211 of the ink tank 2 as the volume of the refill 300 from the fill container 32 takes up as a newly available writing medium 200 in volume in the ink reservoir 22. The air cannula 151, with its piercing tip, penetrates the air seal 213 which is fixedly arranged in the air mouthpiece 24 and thus opens the otherwise hermetically sealed tank space 211 in the ink tank 2. While the ink tank 2 is connected to the distributor housing 11 of the adapter 1 in a frictionally but detachably manner via the tank connection 12 , the container housing 31 of the refill container 3 is located, sealed but relatively loosely seated, in the connection housing 131 of the container connection 13.

Die vorgeschlagene Vorrichtung zum Befüllen eines Tintentanks, insbesondere eines Tintenspeichers bei einem Ink-Jet-System, einem Drucker, Plotter oder einer sonstigen automatischen Registrier-, Schreib- oder Zeichenanlage, weist einen Nachfüllbehälter (3) auf und der Tintentank (2) ist mit diesem durch einen Adapter (1) verbunden und in Füllposition im wesentlichen übereinander angeordnet. Der Adapter weist mindestens zwei Anschlüsse für die zu verbindenden Behälter 3 und Tanks 2 auf und im Tintentank 2 ist ein Tintenspeicher 22 angeordnet, wobei zwischen dem Tankgehäuse 21 und dem Tintenspeicher 22 ein hermetisch abgeschlossener Tankraum 211 ausgebildet ist. Bei einer derartigen Vorrichtung soll vorzugsweise der Adapter 1 derart gestaltet und bemessen sein, dass er zusammen mit einem nachzufüllenden Tintentank 2 und einem geeigneten Nachfüllbehälter 3 in Füllposition, das heißt, in zusammengesetztem Zustand, ein in sich hermetisch abgeschlossenes Füllsystem 14 enthält bzw. bildet und ein zusätzliches Luftsystem 15 aufweist.The proposed device for filling an ink tank, in particular an ink reservoir in an ink jet system, a printer, plotter or other automatic Registration, writing or drawing system, has one Refill container (3) and the ink tank (2) is with this connected by an adapter (1) and in the filling position arranged essentially one above the other. The adapter points at least two connections for the containers to be connected 3 and tanks 2 on and in the ink tank 2 is an ink reservoir 22 arranged, between the tank housing 21 and the Ink storage 22 a hermetically sealed tank room 211 is formed. In such a device preferably the adapter 1 designed and dimensioned in this way be with a refillable ink tank 2 and a suitable refill container 3 in the filling position, that is, in the assembled state, one in itself contains or forms hermetically sealed filling system 14 and has an additional air system 15.

Weiterhin von Vorteil ist es, wenn das Füllsystem 14 mindestens eine, in einem Füllkanal 141 angeordnete, Tankkanüle 142 und eine Behälterkanüle 143 aufweist, die bei angeschlossenem Tintentank 2 und bei eingesetztem Nachfüllbehälter 3 in Füllposition eine fluidische Verbindung zwischen dem Inneren des Füllbehälters 32 und des Tintenspeichers 22 bildet.
Das Luftsystem 15 soll vorzugsweise eine Luftkanüle 151 aufweisen, die in Füllposition, ggf. über eine Luftöffnung 152, einen Luftdurchlass zwischen dem Inneren eines hermetisch abgeriegelten Tankraumes 211 und der Atmosphäre bildet.It is also advantageous if the filling system 14 has at least one tank cannula 142 and a container cannula 143 arranged in a filling channel 141, which, when the ink tank 2 is connected and when the refill container 3 is inserted in the filling position, has a fluidic connection between the interior of the filling container 32 and the Ink storage 22 forms.
The air system 15 should preferably have an air cannula 151 which, in the filling position, possibly via an air opening 152, forms an air passage between the interior of a hermetically sealed tank space 211 and the atmosphere.

Wenn der Adapter 1 ein festes biegesteifes Verteilergehäuse 11 und mindestens einen ebensolchen Tankanschluss 12 und/oder Behälteranschluss 13 aufweist und wenn der Tintentank 2 und/oder der Nachfüllbehälter 3 ebenfalls aus festem biegesteifen Material besteht oder bestehen lässt sich die ganze Vorrichtung besonders stabil ausbilden und leicht handhaben.If the adapter 1 is a rigid, rigid distribution housing 11 and at least one such tank connection 12 and / or container connection 13 and if the Ink tank 2 and / or the refill container 3 also out solid, rigid material exists or can exist the whole device is particularly stable and easy to handle.

Die Dichtungselemente 212, 213, 322 sollen am Tintenspeicher 22, im Tintentank 2, im Nachfüllbehälter 3 und/oder in den Anschlussbereichen des Adapters 1 an diesem selbst angeordnet sein und beim Nachfüllvorgang soll zwischen den Dichtungselementen 212, 213, 322 und den im Adapter 1 angeordneten Kanülen 142, 143, 151 mindestens jeweils eine dichtende Verbindung ausgebildet sein.The sealing elements 212, 213, 322 are intended to be on the ink reservoir 22, in the ink tank 2, in the refill container 3 and / or in the Connection areas of the adapter 1 itself should be arranged and during the refill between the Sealing elements 212, 213, 322 and those in the adapter 1 arranged cannulas 142, 143, 151 at least one each sealing connection be formed.

Wenn die Kanülen 142, 143, 151 mindestens jeweils eine biegesteife Anstechspitze aufweisen, lässt sich der jeweils zugehörige Verschluss am Tintentank 2 und/oder am Nachfüllbehälter 3 besonders einfach und leicht Öffnen.If the cannulas 142, 143, 151 at least one each each have a rigid piercing tip associated closure on the ink tank 2 and / or on Refill container 3 is particularly simple and easy to open.

Günstig ist es bei diesen Systemen auch, wenn der Tintenspeicher 22 des Tintentanks 2 und/oder der Füllbehälter 32 des Nachfüllbehälters 3 eine leicht verformbare Hülle 221, 321 aufweisen, wobei z.B. die Speicherhülle 221 und/oder die Behälterhülle 321 aus einem flexiblen, elastischen Material, vorzugsweise aus einem hochflexiblen Polymermaterial besteht sollten.It is also favorable with these systems if the Ink storage 22 of the ink tank 2 and / or the Filling container 32 of the refill container 3 a light deformable sheath 221, 321, e.g. the Storage sleeve 221 and / or the container sleeve 321 from one flexible, elastic material, preferably made of one highly flexible polymer material should exist.

Die Dichtungselemente 212, 213, 322 können bzw. sollten aus Gummi oder weichem Kunststoff und als Scheiben oder Ringe und/oder als selbstschießende Ventile ausgebildet sein.The sealing elements 212, 213, 322 can or should Rubber or soft plastic and as discs or rings and / or be designed as self-firing valves.

Die Verbindungsmittel am Tankanschluss 12 und/oder am Behälteranschluss 13 des Adapters 1, sollen jeweils komplementär zu den zu verbindenden Tintentanks 2 und Nachfüllbehältern 3 als Steckverbindungen, formschlüssige Verbindungen oder als Gewindeanschlüsse ausgebildet sein.The connecting means on the tank connection 12 and / or on Container connection 13 of the adapter 1 should complementary to the ink tanks 2 and Refill containers 3 as plug connections, positive Connections or be designed as threaded connections.

Erfindungsgemäß wurde eine Vorrichtung geschaffen, die als Adapter 1 eine fluidische Verbindung über ein Füllsystem 14 zwischen einem nachzufüllenden Tintentank 2 und einem Nachfüllbehälter 3 über Kupplungselemente herstellt. Beim Nachfüllen liegt das Flüssigkeitsniveau des Nachfüllbehälters 3 über dem Niveau des Tintentanks 2, damit der Nachfüllvorgang durch Schwerkraft abläuft. Für einen reibungslosen Füllvorgang muss gleichzeitig mit der fluidischen Verbindung ein Druckausgleich bzw. ein Öffnen des hermetisch abgeschlossenen Tankraumes 211, der zwischen der äußeren Oberfläche des Tintenspeichers 22 und der Innenfläche des Tankgehäuse 21 liegt, zur Atmosphäre hergestellt werden. Diese Verbindung erfolgt über ein Belüftungssystem 15 im Adapter 1.According to the invention, a device has been created which can be used as Adapter 1 a fluid connection via a filling system 14 between a refillable ink tank 2 and a Refills container 3 via coupling elements. At the Refilling is the liquid level of the Refill container 3 above the level of the ink tank 2, so the refilling process takes place by gravity. For one smooth filling process must be carried out simultaneously with the fluidic connection a pressure equalization or an opening of the hermetically sealed tank space 211, which between the outer surface of the ink reservoir 22 and the Inner surface of the tank housing 21 lies to the atmosphere getting produced. This connection is made via a Ventilation system 15 in the adapter 1.

Damit erfüllt der Adapter 1 gleichzeitig die Funktionen der Herstellung einer fluidischen Verbindung und die Schaffung eines Luftausgleichs.
Sowohl bei dem Nachfüllbehälter 3 als auch beim Tintentank 2 mit dem Tintenspeicher 22, sind die Anschlüsse mit Dichtelementen 212, 213 und 322, wie beispielsweise mit Septen oder Ventilen verschlossen. Diese Dichtelemente 212, 213, 322 werden beim Andocken des Nachfüllbehälters 3 mit dem Füllbehälter 32 und des Tintentanks 2 mit dem Tintenspeicher 22 an den Adapter 1 von den Kanülen 1142, 143 und 151 durchstochen.
Werden nach dem Nachfüllvorgang der befüllte Tintenspeicher 22 und der entleerte oder auch nur teilentleerte Füllbehälter 32 vom Adapter 1 getrennt bzw. abgezogen, schließen die Dichtelemente 212,213,322 selbsttätig, sobald die Kupplungselemente abgezogen sind. Auf diese Weise wird ein unbeabsichtigtes Austreten von Flüssigkeit wie Tinte 200 oder sonstiges Nachfüllmittel 300 und damit verbundene Verschmutzungen sicher verhindert.
Um Verwechslungen beim einsetzen eines Nachfüllbehälters 3 oder des Tintentanks 2, die unterschiedlich gefärbte Tinten oder Tinten für unterschiedliche Anwendungen enthalten, in den Adapter 1 zu vermeiden, können die Behälteranschlüsse 13 des Adapters 1, Elemente wie Führungsnuten 132 aufweisen, die mit korrespondierenden Elementen am Nachfüllbehälter 3 oder am Tintentank 2 wie beispielsweise Nasen oder Nocken zusammen wirken, z.B. nach dem sogenannten Nut- und Feder-Prinzip.The adapter 1 thus simultaneously fulfills the functions of establishing a fluidic connection and creating an air balance.
Both in the refill container 3 and in the ink tank 2 with the ink reservoir 22, the connections are sealed with sealing elements 212, 213 and 322, such as with septa or valves. These sealing elements 212, 213, 322 are pierced by the needles 1142, 143 and 151 when the refill container 3 with the fill container 32 and the ink tank 2 with the ink reservoir 22 are docked onto the adapter 1.
If, after the refilling process, the filled ink reservoir 22 and the emptied or only partially emptied filling container 32 are separated or removed from the adapter 1, the sealing elements 212, 213, 322 automatically close as soon as the coupling elements are removed. In this way, an unintentional leakage of liquid such as ink 200 or other refill agent 300 and the associated contamination are reliably prevented.
In order to avoid confusion when inserting a refill container 3 or the ink tank 2, which contain differently colored inks or inks for different applications, into the adapter 1, the container connections 13 of the adapter 1 can have elements such as guide grooves 132, which correspond to corresponding elements on the refill container 3 or act together on the ink tank 2, such as noses or cams, for example according to the so-called tongue and groove principle.

Der Nachfüllvorgang sollte zweckmäßigerweise damit begonnen werden, dass zunächst der leere Tintentank 2 mit dem Adapter 1 sicher verbunden und geöffnet wird und dass dann erst der Nachfüllbehälter 3 eingesetzt und geöffnet wird.
Die Füllmengen von Tintentank 2 und Nachfüllbehälter 3 sollten so aufeinander abgestimmt sein, dass der Inhalt des Nachfüllbehälters 3 bei einem Befüllungsvorgang vollständig in den Tintentank 2 eingefüllt werden kann. Andernfalls sind vorteilhaft Absperrventile oder sonstige Portionierungshilfen und/oder Inhalts- und Füllanzeigen anzubringen.The refilling process should expediently begin by first securely connecting and opening the empty ink tank 2 to the adapter 1 and then inserting and opening the refill container 3.
The filling quantities of the ink tank 2 and the refill container 3 should be coordinated with one another in such a way that the contents of the refill container 3 can be completely filled into the ink tank 2 during a filling process. Otherwise shut-off valves or other portioning aids and / or content and filling indicators should be attached.

Nach dem Füllvorgang werden die drei Komponenten Adapter 1, Tintentank 2 und Nachfüllbehälter 3 - vorzugsweise durch senkrechte Abzugsbewegungen - wieder voneinander getrennt. Hierbei verschließen sich vorteilhafter weise die drei Dichtungen 213, 212, und 322 - möglichst auch in dieser Reihenfolge - selbsttätig luft- und flüssigkeitsdicht. Wenn - bei gleichen Anschlusslängen des Tankmundstückes 23 und des Luftmundstückes 24 - die freie Kontaktlänge der Luftkanüle 151 kürzer ist als die freie Anschlusslänge der Tankkanüle 142 wird ein relativ verschmutzungssicheres Lösen des Tintentanks 2 in der vorgegebenen Verschlussfolge ermöglicht, wenn der Tintentank 2 vor dem Nachfüllbehälter 3 entfernt wird.

In this case, the three seals 213, 212, and 322 advantageously close automatically, if possible also in this order, in an airtight and liquid-tight manner. If - with the same connection lengths of the tank mouthpiece 23 and the air mouthpiece 24 - the free contact length of the air cannula 151 is shorter than the free connection length of the tank cannula 142, the ink tank 2 can be loosened in a relatively contamination-proof manner in the predetermined closure sequence if the ink tank 2 in front of the refill container 3 Will get removed. positions: 1 adapter 11 Distributor housing, 12 Tank connection (here as plug connection), 121 Connection body, 123 filling connection, 124 Air connection, 13 Container connection (plug connection), 131 Connection housing, 132 guide, 14 filling system, 141 filling channel, 142 Tank cannula 143 Container cannula 15 Air system, 151 Air cannula 152 Air opening, 2 ink tank 200 Ink / writing materials (in 22), 21 Tank housing 211 Tank room (hermetically sealed), 212 Tank Seal, 213 Air seal, 22 Ink reservoir, 221 Storage cover, 23 Tank mouthpiece 24 Air mouthpiece; 3 refill 300 Refill agent (in 32), 31 Container housing, 311 Container space, 312 Container opening, 32 Storage capacities, 321 container shell 322 container seal
