Abstract

An ink cartridge (10) having an ink reservoir which delimits in a first chamber (17) a free-ink volume (16) and in a second chamber (18) a capillary volume (15), there being an ink outlet (21) associated with the latter, and wherein for use of the cartridge both chambers (17, 18) are connectible to the external environment by way of air-admission openings (23, 24) which prior to use are closed by a removable or peelable film or so-called remove film (25). The air-admission openings (23, 24) are arranged with respect to one another in such a way that when the remove film (25) is peeled off it is always the chamber (18) delimiting the capillary volume (15) to which air is admitted first.

Description

Die vorliegende Erfindung betrifft eine Tintenpatrone, insbesondere Tintenpatrone für einen Tintenstrahldrucker, mit einem Tintenreservoir, welches in einer ersten Kammer ein Freitintenvolumen und einer zweiten ein Kapillarvolumen begrenzt, wobei letzterem ein Tintenauslaß zugeordnet ist, und wobei beide Kammern zum Gebrauch der Patrone mit der äußeren Umgebung über Belüftungsöffnungen verbindbar sind, die vor dem Gebrauch durch eine Entfern- oder abziehbare bzw. sogenannte Remove-Folie verschlossen sind.The present invention relates to an ink cartridge, particularly ink cartridge for an ink jet printer, having an ink reservoir defining a free ink volume in a first chamber and a capillary volume secondly associated with an ink outlet and both chambers for using the cartridge with the external environment can be connected via ventilation openings which are closed by a removable or removable or so-called remove film before use.

Derartige Zweikammer-Tintenpatronen sind allgemein bekannt (zum Beispiel EP1598196). Die eine Kammer ist mit Flüssigtinte und die andere mit einem Tintenspeicherelement, z.B. Schwamm od. dgl. gefüllt. Zwischen den beiden Kammern besteht eine Fluidverbindung, so daß das Speicherelement einem diesem zugeordneten Tintenauslaß stets ausreichend Tinte zur Verfügung stellt, und zwar so lange, bis die Tinte weitgehend aufgebraucht ist. Die beiden Kammern müssen beim Gebrauch mit der äußeren Umgebung in Verbindung sein, um einen Druckausgleich innerhalb der Tintenpatrone bei Entnahme von Tinte durch den Tintenauslaß sicherzustellen. Natürlich ist es erforderlich, die entsprechenden Belüftungsöffnungen nach dem Befüllen der Tintenpatrone zu verschließen. Herkömmlich erfolgt dies mit einer sogenannten Remove-Folie. Vor dem Gebrauch wird diese Remove-Folie abgezogen. Dabei ist es jedoch sehr wichtig, daß die Belüftung der beiden Kammern in der richtigen Reihenfolge erfolgt; denn der beim Öffnen der Belüftungsöffnungen entstehende Druckausgleich zwischen den beiden Kammern und der Umgebung führt bei unsachgemäßer Handhabung zu unerwarteten Tintenspritzern.Such dual-chamber ink cartridges are well known (for example, EP1598196). One chamber is filled with liquid ink and the other with an ink storage element, eg sponge or the like. There is fluid communication between the two chambers so that the storage element will always provide sufficient ink to an ink outlet associated with it, until such time as the ink is substantially exhausted. The two chambers must be in communication with the external environment in use to ensure pressure equalization within the ink cartridge as ink is withdrawn through the ink outlet. Of course, it is necessary to close the corresponding vents after filling the ink cartridge. Conventionally, this is done with a so-called remove film. Before use, this Remove foil is removed. However, it is very important that the ventilation of the two chambers takes place in the correct order; because the pressure equalization between the two chambers and the surrounding area when opening the ventilation openings leads to unexpected ink drops if handled improperly.

Dieses Problem wird bisher durch eine Remove-Folie gelöst, die sich über die beiden, den beiden vorgenannten Kammern der Tintenpatrone jeweils zugeordneten Belüftungsöffnungen erstreckt, wobei diese Belüftungsöffnungen in der Regel hintereinander in der Deckelwand der Tintenpatrone ausgebildet sind, und auf die ein Pfeil aufgedruckt ist, der auf die Abzugsrichtung der Remove-Folie hinweist. Wenn diese Abzugsrichtung eingehalten wird, wird zuerst die der Speicherkammer zugeordnete Belüftungsöffnung und anschließend die der Freitinten-Kammer zugeordnete Belüftungsöffnung freigegeben. Damit erfolgt der Druckausgleich zwischen den beiden Kammern einerseits und der äußeren Umgebung andererseits zunächst über die Speicherkammer, d.h. die Kammer, welche das sogenannte Kapillarvolumen begrenzt. Aufgrund des Speicherelements in dieser Kammer wird bei der Herstellung des Druckausgleichs ein unerwartetes Austreten von Tinte durch die der Speicherkammer zugeordnete Belüftungsöffnung hindurch verhindert. Nachteilig ist jedoch, daß bei Nichteinhaltung der Abzugsrichtung der Remove-Folie die Freitinten-Kammer zuerst belüftet wird mit der Folge, daß durch die entsprechende Belüftungsöffnung unerwartet Tinte austreten kann.This problem has previously been solved by a remove film which extends over the two, the two aforementioned chambers of the ink cartridge respectively associated ventilation openings, these ventilation openings are usually formed one behind the other in the top wall of the ink cartridge, and on which an arrow is printed that indicates the direction of removal of the Remove slide. If this withdrawal direction is maintained, first the ventilation opening associated with the storage chamber and then the ventilation opening associated with the free-ink chamber is released. Thus, the pressure equalization between the two chambers on the one hand and the external environment on the other hand initially via the storage chamber, i. the chamber, which limits the so-called capillary volume. Due to the storage element in this chamber, in the production of the pressure equalization, an unexpected leakage of ink through the ventilation opening associated with the storage chamber is prevented. The disadvantage, however, is that failure to comply with the deduction direction of the remove film, the free ink chamber is first ventilated with the result that unexpectedly escape through the corresponding vent opening.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Tintenpatrone der eingangs genannten Art zur Verfügung zu stellen, bei der vor Ingebrauchnahme unerwartete Tintenspritzer sicher vermieden werden.The present invention is therefore an object of the invention to provide an ink cartridge of the type mentioned in the unexpected before use of ink splashes are avoided.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Maßnahmen des Anspruches 1 gelöst, wobei vorteilhafte Weiterbildungen und Ausführungsformen in den Unteransprüchen beschrieben sind.This object is achieved by the characterizing measures of claim 1, wherein advantageous developments and embodiments are described in the dependent claims.

Ein wesentlicher Gedanke der vorliegenden Erfindung liegt also darin, die Belüftungsöffnungen, die dem Freitintenvolumen einerseits und Kapillarvolumen andererseits zugeordnet sind, so zueinander anzuordnen, daß beim Abziehen der Remove-Folie stets zuerst die das Kapillarvolumen begrenzende Kammer der Tintenpatrone belüftet wird. Der Benutzer muß also nicht mehr darauf achten, daß er die Remove-Folie entsprechend eines aufgedruckten Pfeiles oder ähnlichen Anweisung abzieht. Unabhängig von der Abzugsrichtung soll also erfindungsgemäß gewährleistet sein, daß stets zuerst die das Kapillarvolumen begrenzende Kammer belüftet wird.An essential idea of the present invention is thus to arrange the ventilation openings, which are assigned to the free-ink volume on the one hand and capillary volume on the other hand, so that when removing the remove film always first the capillary volume limiting chamber of the ink cartridge is vented. Thus, the user no longer has to be careful to peel off the remove sheet according to a printed arrow or similar instruction. Regardless of the withdrawal direction should therefore be ensured according to the invention that always first the capillary volume limiting chamber is vented.

Sofern die Remove-Folie nur eine bestimmte bzw. bevorzugte Abzugsrichtung erlaubt, sollen die Belüftungsöffnungen so ausgebildet und angeordnet sein, daß die dem Freitintenvolumen zugeordnete Belüftungsöffnung zwischen zwei dem Kapillarvolumen zugeordneten Belüftungsöffnungen angeordnet ist. Dann ist es nämlich gleichgültig, ob die Remove-Folie von links nach rechts oder von rechts nach links in der bevorzugten Abzugsrichtung vor Gebrauch der Tintenpatrone abgezogen wird.If the remove film allows only a certain or preferred direction of withdrawal, the ventilation openings should be designed and arranged so that the free ink volume associated ventilation opening between two capillary volume associated ventilation openings. For then it does not matter if the Remove foil from left to right or right to left in the preferred direction of withdrawal before using the ink cartridge.

Um auf jeden Fall eine Belüftung der das Kapillarvolumen begrenzenden Kammer vor der das Freitintenvolumen begrenzenden Kammer unabhängig von der Abzugsrichtung der Remove-Folie sicherzustellen, sind die Belüftungsöffnungen vorzugsweise ineinander allgeordnet unter Ausbildung einer inneren, dem Freitintenvolumen zugeordneten Belüftungsöffnung und einer äußeren, die innere Belüftungsöffnung ringförmig umgebenden und dem Kapillarvolumen zugeordneten Belüftungsöffnung. In diesem Fall ist gewährleistet, daß immer zuerst die dem Kapillarvolumen zugeordnete Kammer zum Zwecke des Druckausgleichs geöffnet wird. Erst dann erfolgt die Belüftung der das Freitintenvolumen begrenzenden Kammer. Ein unerwartetes Austreten von Tinte aus letzterer bedingt durch den hergestellten Druckausgleich bei Entfernung der Remove-Folie wird dann sicher ausgeschlossen.In any event, to ensure ventilation of the capillary volume limiting chamber in front of the free ink volume limiting chamber, regardless of the removal direction of the remove sheet, the ventilation openings are preferably interleaved to form an inner, the free ink volume associated vent opening and an outer, the inner vent opening annular surrounding and the capillary volume associated ventilation opening. In this case, it is ensured that always the first chamber associated with the capillary volume is opened for the purpose of pressure equalization. Only then is the ventilation of the free ink volume limiting chamber. An unexpected leakage of ink from the latter due to the prepared pressure compensation on removal of the remove film is then safely excluded.

Eine besonders einfache Ausführungsform, und zwar sowohl hinsichtlich der Handhabung als auch der Herstellung ist dadurch gekennzeichnet, daß durch die Remove-Folie sowohl die Belüftungsöffnungen als auch der Tintenauslaß verschließbar sind. Für all diese Öffnungen ist dann nur noch eine einzige Remove-Folie erforderlich. Gerade bei dieser Ausführungsform ist die erfindungsgemäße Ausbildung und Anordnung der Belüftungsöffnungen von großer Bedeutung; denn es ist dann gleichgültig, ob die Remove-Folie ausgehend von den Belüftungsöffnungen oder ausgehend vom Tintenauslaß abgezogen wird. In jedem Fall ist sichergestellt, daß zuerst die das Kapillarvolumen begrenzende Kammer belüftet wird.A particularly simple embodiment, both in terms of handling and the production is characterized in that both the ventilation openings and the ink outlet can be closed by the remove film. For all these openings then only a single remove film is required. Especially in this embodiment, the inventive design and arrangement of the ventilation openings is of great importance; because it does not matter if the remove film is removed from the vents or from the ink outlet. In any case, it is ensured that first the capillary volume limiting chamber is vented.

Eine bevorzugte Ausführungsform einer Tintenpatrone umfaßt vier Seitenwände, eine Bodenwand und eine Deckelwand, wobei der Tintenauslaß entweder in der Bodenwand oder bodennah in einer Seitenwand angeordnet ist. Die Belüftungsöffnungen sind in der Deckelwand angeordnet, und zwar vorzugsweise in möglichst geringem Abstand zum Tintenauslaß, d.h. möglichst nahe der Seitenwand, an der sich der Tintenauslaß befindet, bzw. die an die Seite der Bodenwand anschließt, an der sich der Tintenauslaß befindet.A preferred embodiment of an ink cartridge comprises four side walls, a bottom wall and a top wall, wherein the ink outlet is disposed either in the bottom wall or near the bottom in a side wall. The ventilation openings are arranged in the top wall, preferably at the smallest possible distance from the ink outlet, i. as close as possible to the side wall at which the ink outlet is located, or which adjoins the side of the bottom wall at which the ink outlet is located.

Die in den Figuren 1 und 2 schematisch dargestellte Tintenpatrone ist mit der Bezugsziffer 10 gekennzeichnet. Diese Tintenpatrone umfaßt vier Seitenwände, und zwar zwei gegenüberliegende Flachseitenwände 11 und zwei gegenüberliegende Stirnseitenwände 12, sowie eine Deckelwand 13 und Bodenwand 14. Die Deckelwand 13 wird durch einen gesonderten Deckel gebildet, der nach Montage eines ein Kapillarvolumen 15 definierendes Tinten-Speicherelement innerhalb der Tintenpatrone mit den oberen Kanten der Seitenwände der Tintenpatrone verklebt oder verschweißt wird. Das das Kapillarvolumen 15 definierende Tinten-Speicherelement kann aus offenporigem Schaumstoff oder Fasermaterial bestehen. Hierbei handelt es sich um eine an sich bekannte Maßnahme, die hier nicht näher beschrieben werden muß. Die das vorgenannte Kapillarvolumen begrenzende Kammer 18 ist mit einer weiteren Kammer 17 über einen bodennahen Durchgang 19 fluidverbunden, wobei die Kammer 17 ein sogenanntes Freitintenvolumen 16 begrenzt. In dieser Kammer 17 befindet sich also Flüssigtinte. Die beiden Kammern 17 und 18 sind innerhalb der Patrone durch eine Zwischenwand 20 voneinander getrennt, wobei sich der vorgenannte Fluiddurchgang 19 am unteren bzw. bodennahen Ende der Zwischenwand 20 befindet. Über diesen Fluiddurchgang 19 wird das Kapillarvolumen 15 mit Tinte aus der Kammer 17 versorgt. In der Bodenwand 14 ist dem Kapillarvolumen 15 zugeordnet ein Tintenauslaß 21 ausgebildet. Über diesen erfolgt die Zufuhr von Tinte aus der Patrone zu einem Druckkopf eines Tintenstrahldruckers.The in the Figures 1 and 2 schematically illustrated ink cartridge is indicated by the reference numeral 10. This ink cartridge comprises four side walls, namely two opposite flat side walls 11 and two opposite end walls 12, and a top wall 13 and bottom wall 14. The top wall 13 is formed by a separate lid, which after assembly of a capillary volume 15 defining ink storage element within the ink cartridge glued or welded to the upper edges of the side walls of the ink cartridge. The ink storage element defining the capillary volume 15 can consist of open-pored foam or fiber material. This is a known measure, which need not be described in detail here. The aforementioned capillary volume limiting chamber 18 is fluidly connected to another chamber 17 via a bottom-near passage 19, wherein the chamber 17 defines a so-called free ink volume 16. In this chamber 17 is thus liquid ink. The two chambers 17 and 18 are separated from each other within the cartridge by an intermediate wall 20, wherein the aforementioned fluid passage 19 is located at the bottom or bottom end of the intermediate wall 20. About this fluid passage 19, the capillary volume 15 is supplied with ink from the chamber 17. In the bottom wall 14 of the capillary 15 associated with an ink outlet 21 is formed. About this, the supply of ink from the cartridge to a printhead of an inkjet printer.

In die Kammer 17 ragt ausgehend von der Deckelwand 13 noch ein sogenannter Bubble-Generator hinein, der in Fig. 2 mit der Bezugsziffer 22 gekennzeichnet ist.In the chamber 17 protrudes from the top wall 13 still a so-called bubble generator into it, the in Fig. 2 designated by the reference numeral 22.

Im folgenden wird die Kammer 17 als erste Kammer und die Kammer 18 als zweite Kammer bezeichnet.In the following, the chamber 17 is referred to as a first chamber and the chamber 18 as a second chamber.

Beiden Kammern 17, 18 sind Belüftungsöffnungen 23, 24 zugeordnet, über die zum Gebrauch der Patrone 10 eine Verbindung mit der äußeren Umgebung hergestellt werden kann. Damit ist es möglich, einen Druckausgleich zwischen den beiden Kammern einerseits und mit der Umgebung andererseits herzustellen, so daß die Tintenzufuhr durch den Tintenauslaß 21 gewährleistet ist. Vor dem Gebrauch sind die beiden Belüftungsöffiiungen durch eine entfern- oder abziehbare bzw. sogenannte Remove-Folie 25 verschlossen. Die beiden Belüftungsöffnungen 23, 24 sind bei der dargestellten Ausführungsform (siehe Fig. 1) ineinander angeordnet unter Ausbildung einer inneren, dem Freitintenvolumen 16 bzw. der ersten Kammer 17 zugeordneten Belüftungsöffnung 23 und einer äußeren, die innere Belüftungsöffnung 23 ringförmig umgebenden und dem Kapillarvolumen 15 bzw. der zweiten Kammer 18 zugeordneten Belüftungsöffnung 24. Beim Abziehen der Remove-Folie 25 z.B. entsprechend Fig. 1 ist damit sichergestellt, daß stets zuerst die dem Kapillarvolumen 15 zugeordnete Belüftungsöffnung 24 freigegeben wird. Dementsprechend wird zuerst die zweite, das Kapillarvolumen 15 begrenzende Kammer 18 belüftet. Erst anschließend erfolgt die Belüftung der das Freitintenvolumen 16 begrenzenden Kammer 17. Aus dieser Öffnung kann aufgrund des bereits erfolgten Druckausgleiches über die Öffnung 23 keine Tinte mehr unerwartet herausspritzen.Both chambers 17, 18 are associated with ventilation openings 23, 24, via which a connection with the external environment can be established for the use of the cartridge 10. Thus, it is possible to make a pressure equalization between the two chambers on the one hand and with the environment on the other hand, so that the ink supply is ensured by the ink outlet 21. Before use, the two ventilation openings are closed by a removable or removable or so-called remove film 25. The two ventilation openings 23, 24 are in the illustrated embodiment (see Fig. 1 ) arranged inside each other to form an inner, the free ink volume 16th or the first chamber 17 associated ventilation opening 23 and an outer, the inner ventilation opening 23 annularly surrounding and the capillary volume 15 and the second chamber 18 associated ventilation opening 24. When removing the Remove film 25, for example, accordingly Fig. 1 This ensures that always the first capillary volume 15 associated ventilation opening 24 is released. Accordingly, first the second, the capillary volume 15 bounding chamber 18 is vented. Only then does the ventilation of the free ink volume 16 limiting chamber 17. From this opening, due to the already made pressure equalization through the opening 23 no more ink splash out unexpectedly.

Bei der dargestellten Ausführungsform sind durch die Remove-Folie 25 sowohl die Belüftungsöffnungen 23, 24 als auch der Tintenauslaß 21 verschlossen. Insofern erfüllt die Remove-Folie eine Art Doppelfunktion.In the illustrated embodiment, both the ventilation openings 23, 24 and the ink outlet 21 are closed by the remove film 25. In this respect, the Remove slide fulfills a kind of dual function.

Die Belüftungsöffnungen 23, 24 sind - wie bereits erwähnt - in der Deckelwand 13 angeordnet, und zwar bei der dargestellten Ausführungsform dem Tintenauslaß 21 etwa gegenüberliegend.The ventilation openings 23, 24 are - as already mentioned - arranged in the top wall 13, in the illustrated embodiment, the ink outlet 21 approximately opposite.

Natürlich sind die Öffnungen 23, 24 über in der Deckelwand 13 ausgebildete Kanäle mit den beiden vorgenannten Kammern 17, 18 verbunden. Diese Kanäle sind in Fig. 1 gestrichelt angeordnet. Die Belüftungsöffnung 23 ist über einen ersten Kanal 26 und eine in die erste Kammer 17 mündende Öffnung 27 mit der ersten Kammer 17 verbunden, während die Belüftungsöffnung 24 über einen zweiten Kanal 28 und eine in die zweite Kammer mündende Öffnung 29 mit der zweiten Kammer 18 verbunden ist.Of course, the openings 23, 24 connected via formed in the top wall 13 channels with the two aforementioned chambers 17, 18. These channels are in Fig. 1 arranged dashed. The ventilation opening 23 is connected to the first chamber 17 via a first channel 26 and an opening 27 opening into the first chamber 17, while the ventilation opening 24 is connected to the second chamber 18 via a second channel 28 and an opening 29 opening into the second chamber is.

Die vorgenannte Öffnung 27 ist im übrigen Teil des vorerwähnten Bubble-Generators, über den der Druckausgleich in der das Freitintenvolumen 16 begrenzenden ersten Kammer 17 erfolgt. Die dabei von außen nachströmende Luft wird über den Bubble-Generator 22 blasenweise in die erste Kammer 17 eingeleitet, wobei die entsprechende Öffnung am unteren Ende des Bubble-Generators 22 schlitzartig ausgebildet und so klein ist, daß zwar Luftblasen in die Freitinte eintreten können, Freitinte jedoch nicht ohne weiteres nach außen dringt.The aforementioned opening 27 is in the remaining part of the aforementioned bubble generator, via which the pressure compensation in the free ink volume 16 limiting first chamber 17 takes place. The air flowing in from the outside is introduced bubble-wise into the first chamber 17 via the bubble generator 22, the corresponding opening being slit-like at the lower end of the bubble generator 22 and being so small that air bubbles can enter the free ink, free-ink however, does not readily escape to the outside.

Die Remove-Folie 25 ist oberhalb der Belüftungsöffnungen 23, 24 noch nach rückwärts gefaltet, um eine entsprechende Grifflasche 30 zu definieren. Dementsprechend bietet es sich für den Benutzer an, die Remove-Folie zunächst an der vorerwähnten Grifflasche zu greifen und ausgehend von dort abzuziehen unter gleichzeitiger Öffnung der BelüftungsÖffnungen 23, 24 in der oben beschriebenen Weise. Anschließend erfolgt die Öffnung des Tintenauslasses 21. Es ist jedoch genauso gut denkbar, die Remove-Folie 25 ausgehend vom Tintenauslaß 21, über den sie ja etwas vorsteht, abzuziehen.The remove film 25 is still folded backwards above the ventilation openings 23, 24 in order to define a corresponding grip tab 30. Accordingly, it is convenient for the user to first grip the Remove foil on the aforementioned grip tab and withdraw it therefrom while simultaneously opening the vent openings 23, 24 in the manner described above. Subsequently, the opening of the ink outlet 21 takes place. However, it is just as conceivable to remove the remove film 25 from the ink outlet 21, over which it projects somewhat.
