Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Tintenpatrone sowie eine Tintenpatroneneinheit und einen Tintenstrahldruckkopf, welche jeweils eine derartige Tintenpatrone umfassen für den Einsatz in einem Tintenstrahldrucker.The invention relates to an ink cartridge and to an ink cartridge unit and to an inkjet printhead, each comprising such an ink cartridge for use in an inkjet printer.

Stand der TechnikState of the art

Aus der US-6 149 267 A ist eine gattungsgemässe Tintenpatrone bekannt, bei welcher als Tintenauslass lediglich eine Oeffnung in der Wand der Kammer vorgesehen ist. Wird die Tintenpatrone in einen passenden Adapter eingesetzt, so liegt ein Stutzen desselben mit etwas seitlichem Spiel in der Oeffnung. Dies hat den Nachteil, dass dort neben dem Stutzen Tinte austreten kann, welche den Adapterverschmutzt. Umgekehrt kann beim Einsetzen der Tintenpatrone Luft eingeschlossen werden, was u.U. zu einer Unterbrechung des Tintenpfades führt. Daher ist es erforderlich, an der dem Tintenauslass entgegengesetzten Seite des Gehäuses ein Pumpelement vorzusehen, mittels dessen Druck in der Kammer aufgebaut und die Tinte durch die Auslassöffnung getrieben werden kann. Ein solches Pumpelement verteuert jedoch die Tintenpatrone. Ausserdem ist es lästig, dass die nach dem Einsetzen meist schlecht zugängliche Tintenpatrone noch durch Pumpen gebrauchsfertig gemacht werden muss.From the US 6,149,267 A a generic ink cartridge is known in which only one opening in the wall of the chamber is provided as the ink outlet. If the ink cartridge inserted into a suitable adapter, so it is a neck of the same with a little lateral play in the opening. This has the disadvantage that ink can escape there in addition to the neck, which contaminates the adapter. Conversely, when inserting the ink cartridge, air may be trapped, possibly resulting in an interruption of the ink path. Therefore, it is necessary to provide at the side of the housing opposite the ink outlet a pumping element by means of which pressure can be built up in the chamber and the ink can be driven through the outlet opening. However, such a pump element makes the ink cartridge more expensive. It is also annoying that the ink cartridge, which is usually difficult to access after insertion, still has to be made ready for use by pumping.

Bei einer im übrigen ähnlichen Lösung ( US-5 784 088 A ) ist daher der Stutzen des Adapters an seiner Basis von einem Dichtungsring umgeben, der gegen das Gehäuse der Tintenpatrone drückt. Auch diese Lösung ist nicht befriedigend, da der zwischen dem Speicherkörper und dem Dichtungsring liegende Zwischenraum zwischen dem Stutzen und einem ihn aufnehmenden Kragen der Tintenpatrone trotzdem verschmutzen kann. Ausserdem ist der Dichtungsring nur schwer zu montieren, wenn der Adapter ein Aufnahmefach für die Tintenpatrone aufweist, wie es im Hinblick auf eine sichere Befestigung und Führung derselben beim Einsetzen wünschenswert ist.In an otherwise similar solution ( U.S. 5,784,088 ) is therefore the nozzle of the adapter at its base surrounded by a sealing ring which presses against the housing of the ink cartridge. Also, this solution is not satisfactory, since the gap between the storage body and the sealing ring between the nozzle and a receiving collar of the ink cartridge can still pollute. In addition, the sealing ring is difficult to assemble when the adapter has a receptacle for the ink cartridge, as it is desirable in terms of secure attachment and guidance of the same when inserting.

Gemäss US-5 767 881 A ist bei sonst ähnlicher Ausbildung an der Aussenseite des Stutzens ein Dichtungsring angeordnet, der mit dem Kragen, der den Stutzen aufnimmt, zusammenwirkt. Der Dichtungsring ist jedoch am Grund des Aufnahmefachs verhältnismässig schwerzu montieren. Ausserdem muss erbei eingesetzter Tintenpatrone etwas zusammengepresst sein, damit die Dichtung zuverlässig wirkt. Daher ist beim Entfernen und beim Einsetzen der Tintenpatrone eine verhältnismässig grosse Reibung zwischen dem Dichtungsring und dem Kragen zu überwinden, was diese Vorgänge erschwert. Der Tintenpfad im Adapter kann leicht unterbrochen werden, da zwischen der vorgeschobenen, von einer porösen Platte verschlossenen Aufnahmeöffnung und einem zwischen derselben und der Düsenplatte eingebauten Sieb grössere Hohlräume liegen. Daher ist auch hier ein Pumpelement erforderlich, das die Tintenpatrone verteuert und ihre Bedienung erschwert.According to US-5 767 881 A is at otherwise similar training on the outside of the nozzle, a sealing ring arranged, which cooperates with the collar which receives the neck. However, the sealing ring is relatively difficult to mount at the bottom of the receiving compartment. In addition, it must be slightly compressed with inserted ink cartridge so that the seal works reliably. Therefore, a relatively large friction between the sealing ring and the collar to overcome during removal and insertion of the ink cartridge, which makes these operations difficult. The ink path in the adapter can be easily interrupted, since there are larger cavities between the advanced, closed by a porous plate receiving opening and a built-in between the same and the nozzle plate screen. Therefore, a pump element is also required here, which makes the ink cartridge more expensive and difficult to operate.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zu Grunde, eine gattungsgemässe Tintenpatrone anzugeben, welche mit einem einfach aufgebauten Adapter so zusammenwirken kann, dass der Tintenpfad zuverlässig abgedichtet ist, so dass keine störenden Verschmutzungen auftreten können und dass sie zugleich leicht einsetzbar und entfernbar ist. Diese Aufgabe wird durch die Merkmale im Kennzeichen des Anspruchs 1 gelöst.The invention is based on the object to provide a generic ink cartridge, which can cooperate with a simple design adapter so that the ink path is reliably sealed so that no disturbing contamination can occur and that it is also easy to use and removable. This object is solved by the features in the characterizing part of claim 1.

Die erfindungsgemässe Tintenpatrone kann durch gerades, im wesentlichen reibungsfreies Einschieben auf einfache Weise eingesetzt werden. Der Tintenpfad zum Adapter ist damit ohne weitere Massnahmen hergestellt. Trotzdem ist ein Austreten von Tinte zuverlässig unterbunden. Die erfindungsgemässe Tintenpatrone kann auch sehr leicht wieder entfernt werden.The ink cartridge according to the invention can be used in a simple manner by means of straight, substantially friction-free insertion. The ink path to the adapter is thus made without further measures. Nevertheless, leakage of ink is reliably prevented. The ink cartridge according to the invention can also be removed very easily.

Die Erfindung gibt ausserdem eine Tintenpatroneneinheit an, bei welcher die Auslassöffnung auf sehr einfache Weise zuverlässig verschlossen ist, so dass sie sicher und problemlos transportiert und gelagert werden kann. Zudem wird ein Tintenstrahldruckkopf beschrieben, welcher neben der erfindungsgemässen Tintenpatrone einen Adapter mit Düsenplatte umfasst, an welchem dieselbe befestigbar ist. Der Adapter ist sehr einfach aufgebaut und wirkt so mit der erfindungsgemässen Tintenpatrone zusammen, dass derTintenpfad zuverlässig abgedichtet ist und eine Unterbrechung desselben nicht eintreten kann.The invention also provides an ink cartridge unit in which the outlet port is reliably sealed in a very simple manner so that it can be safely and easily transported and stored. In addition, an inkjet printhead is described which, in addition to the ink cartridge according to the invention, comprises an adapter with nozzle plate to which it can be fastened. The adapter is of a very simple construction and cooperates with the ink cartridge according to the invention in such a way that the ink path is reliably sealed and interruption thereof can not occur.

Wege zur Ausführung der ErfindungWays to carry out the invention

Die erfindungsgemässe Tintenpatrone 1 weist (Fig.1, 5, 6) ein Gehäuse2 auf, das eine Kammer umgibt, welche einen mit Tinte vollgesogenen Speicherkörper 3 aus offenporigem Schaumstoff enthält und die durch einen Deckel 4 mit einer Lüftungsöffnung 5 verschlossen ist. Die Lüftungsöffnung 5 mündet an der Oberseite des Deckels 4 in eine mäanderförmige Vertiefung, die sich am Ende erweitert. Die Vertiefung kann, mit Ausnahme der Erweiterung am Ende, durch z.B. ein Klebeetikett abgedeckt sein und bildet einen Ausdehnungsraum, der erforderlichenfalls Tinte aufnimmt. Am Boden des Gehäuses 2 ist ein Tintenauslass 6 vorgesehen. Dazu weist das Gehäuse dort eine Oeffnung 7 (Fig. 5) auf, in welche eine Dichtung 8 eingesetzt ist.The ink cartridge 1 according to the invention has ( Fig.1 . 5 . 6 ) a housing 2, which surrounds a chamber which contains a saturated with ink storage body 3 of open-cell foam and which is closed by a cover 4 with a ventilation opening 5. The ventilation opening 5 opens at the top of the lid 4 in a meander-shaped depression, which widens at the end. The recess, with the exception of the extension at the end, be covered by, for example, an adhesive label and forms an expansion space, which absorbs ink if necessary. At the bottom of the housing 2, an ink outlet 6 is provided. For this purpose, the housing has an opening 7 (FIG. Fig. 5 ), in which a seal 8 is inserted.

Die Dichtung 8 umfasst eine etwa quadratische Kontaktplatte 9, deren Oberseite an der Unterseite des Gehäuses 2 anliegt und deren Unterseite eine freiliegende Dichtfläche 10 bildet sowie einen an deren Oberseite an die Kontaktplatte 9 anschliessenden, mit ihr einstükkigen Ring 11. Zur Sicherung gegen Verdrehung ist die Kontaktplatte 9 an einer Ecke etwas verkürzt und stösst dort an einen von der Unterseite des Gehäuse 2 abstehenden Nocken. Im Zentrum der Dichtfläche 10 liegt eine Auslassöffnung 12, an die ein vom Ring 11 umgebener Durchlass anschliesst, der sie mit der Kammer im Inneren des Gehäuses 2 verbindet. Der Ring 11 weist am oberen Ende einen radial nach aussen vorstehenden umlaufenden Kragen 13 auf, welcher an der Innenseite des Gehäuses 2 über den etwas eingesenkten Rand der Oeffnung 7 ragt und so die Dichtung 8 in derselben schnappverriegelt, so dass sie nicht ohne Deformation entfernbar ist. Zugleich verbessert der Kragen 13 die Abdichtung zwischen dem Rand der Oeffnung 7 und der Aussenseite des Ringes 11. In der Auslassöffnung 12 liegt ein mit der Dichtung 8 verbundenes Leitelement 14, ein rundes Plättchen, das aus porösem Material, z.B. aus offenporigem Schaumstoff oder aus parallelen Fasern, die axial vom Inneren der Kammer nach aussen führen, besteht.The seal 8 comprises an approximately square contact plate 9, the upper side rests against the underside of the housing 2 and the underside forms an exposed sealing surface 10 and a at the top thereof to the contact plate 9 subsequent, with her einstükkigen ring 11. To secure against rotation is the Contact plate 9 shortened slightly at one corner and abuts there on a projecting from the bottom of the housing 2 cams. In the center of the sealing surface 10 there is an outlet opening 12, to which a passage surrounded by the ring 11 connects, which connects it to the chamber in the interior of the housing 2. The ring 11 has at the upper end a radially outwardly projecting circumferential collar 13 which projects on the inside of the housing 2 on the slightly depressed edge of the opening 7 and so the seal 8 is snap-locked in the same, so that it is not removable without deformation , At the same time the collar 13 improves the seal between the edge of the opening 7 and the outside of the ring 11. In the outlet opening 12 is a guide element 14 connected to the seal 8, a round plate made of porous material, e.g. made of open-cell foam or of parallel fibers, which lead axially from the interior of the chamber to the outside exists.

An den Seitenwänden weist das Gehäuse 2 zwei einander gegenüberliegende kugelkalottenförmige flache Rastnocken 15 auf sowie jeweils etwas unterhalb davon, nicht weit von der Unterkante entfernt, rechteckige Vertiefungen 16. Das Gehäuse 2 und der Deckel 4 bestehen aus Kunststoff, vorzugsweise aus Polypropylen. Der Speicherkörper 3 kann aus PUR bestehen und das Leitelement 14, falls es als Schaumstoffkörper ausgebildet ist, ebenfalls, falls es als Faserbündel ausgebildet ist, aus Polyester. Die Kontaktplatte 9 und der Ring 11 bestehen aus einem Material, das elastisch ist und weicher als das Material des Gehäuses 2, z.B. aus einem thermoplastischen Elastomer.On the side walls, the housing 2 has two opposing spherical cap-shaped flat locking cams 15 and each slightly below it, not far away from the lower edge, rectangular recesses 16. The housing 2 and the lid 4 are made of plastic, preferably polypropylene. The storage body 3 may consist of PUR and the guide element 14, if it is designed as a foam body, also, if it is formed as a fiber bundle, made of polyester. The contact plate 9 and the ring 11 are made of a material that is elastic and softer than the material of the housing 2, e.g. made of a thermoplastic elastomer.

Für Versand und Lagerung ist die Tintenpatrone 1 durch (Fig. 3, 4) ein Verschlussteil 17 zu einer Tintenpatroneneinheit ergänzt. Das einstückige Verschlussteil 17 umfasst eine rechteckige Verschlussplatte 18 sowie an deren gegenüberliegenden Enden etwa rechtwinklig abstehende parallele Halteflügel 19a,b, von denen der Halteflügel 19a eine schräg abstehende Lasche 20 aufweist. Jeder der Halteflügel 19a,b trägt eine gegen den jeweils gegenüberliegenden Halteflügel 19b; a vorspringende Nase 21. Das Verschlussteil 17 ist durch Schnappverriegelung am Gehäuse 2 der Tintenpatrone 1 befestigt, indem die Nasen 21 mit den Vertiefungen 16 eingreifen. Die Oberseite der Verschlussplatte 18 drückt dabei gegen die Dichtfläche 10, so dass die Auslassöffnung 12 zuverlässig und dicht verschlossen ist. Durch Druck gegen die Oberseite der Lasche 20 kann die Schnappverriegelung gelöst und das Verschlussteil 17 abgenommen werden. Das Verschlussteil 17 besteht aus einem verhältnismässig steifen elastischen Kunststoff, z.B. Polypropylen.For shipping and storage, the ink cartridge 1 by ( Fig. 3, 4 ) a closure member 17 added to an ink cartridge unit. The one-piece closure member 17 comprises a rectangular closure plate 18 and at its opposite ends approximately at right angles protruding parallel retaining wings 19a, b, of which the retaining wing 19a has an obliquely protruding tab 20. Die Lasche 20 ist in der Ausnehmung 17 des Gehäuses 19a angeordnet. Each of the retaining wings 19a, b bears against the respectively opposite retaining wing 19b; The projection 17 is snap-locked to the housing 2 of the ink cartridge 1 by engaging the projections 21 with the recesses 16. The top of the closure plate 18 presses against the sealing surface 10, so that the outlet opening 12 is reliably and tightly closed. By pressure against the top of the tab 20, the snap lock can be released and the closure member 17 are removed. The closure member 17 consists of a relatively rigid elastic plastic, eg polypropylene.

Die Tintenpatrone 1 bildet mit einem Adapter 22 (Fig. 2, 5, 6) einen Tintenstrahldruckkopf, wie er in Tintenstrahldruckern verwendet wird. Der Adapter 22 weist ein Gehäuse 23 auf, das ein oben offenes Aufnahmefach 24 bildet, in welches die Tintenpatrone 1 einsetzbar ist. Die Seitenwände des Gehäuses 23 weisen einander gegenüberliegende runde Rastlöcher 25 auf, mit welchen die Rastnocken 15 eingreifen, so dass die eingesetzte Tintenpatrone 1 mit dem Adapter 22 verrastet ist. Am oberen Rand weisen sie ausserdem halbkreisförmige Ausnehmungen 26 auf, welche das Einsetzen und Entfernen der Tintenpatrone 1 erleichtern.The ink cartridge 1 forms with an adapter 22 (FIG. Fig. 2 . 5 . 6 ) an ink jet printhead as used in ink jet printers. The adapter 22 has a housing 23, which forms a receptacle 24 open at the top, into which the ink cartridge 1 can be inserted. The side walls of the housing 23 have mutually opposite round detent holes 25, with which engage the locking cam 15, so that the inserted ink cartridge 1 is locked to the adapter 22. At the top they also have semi-circular recesses 26, which facilitate the insertion and removal of the ink cartridge 1.

An der Unterseite trägt das Gehäuse 23 eine Düsenplatte (nicht dargestellt) zur gesteuerten Abgabe von Tintentropfen. Düsenplatten und ihre Steuerung sind wohlbekannt. Am Grund des Aufnahmefaches 24 weist der Adapter 22 eine von einem abgesetzten Rahmen umgebene Aufnahmeöffnung 27 auf, in welcher ein siebartiger Filter 28 angeordnet ist, der z.B. als Geflecht aus Metalldrähten ausgebildet ist und dem Abfangen grösserer Partikel dient, die sonst die Düsen der Düsenplatte verstopfen könnten, mit denen die Aufnahmeöffnung 27 über einen an dieselbe anschliessenden Hohlraum 29 und (nicht dargestellte) Leitungen in Verbindung steht.At the bottom, the housing 23 carries a nozzle plate (not shown) for the controlled release of ink droplets. Nozzle plates and their control are well known. At the bottom of the receiving compartment 24, the adapter 22 has a receiving opening 27 surrounded by a stepped frame, in which a sieve-like filter 28 is arranged, which is e.g. formed as a braid of metal wires and the interception of larger particles is used, which could otherwise clog the nozzle of the nozzle plate, with which the receiving opening 27 via a connecting thereto the same cavity 29 and (not shown) lines in communication.

Die zwischen dem Adapter 22 und der Tintenpatrone 1 wirksame Rastverbindung ist so angelegt, dass die Dichtfläche 10 frontal gegen den Rahmen der Aufnahmeöffnung 27 drückt, derart, dass der von der Kammer der Tintenpatrone 1 durch die Auslassöffnung 12 und die Aufnahmeöffnung 27 zum Hohlraum 29 führende Tintenpfad gegen aussen, d.h. gegen die umgebenden Bereiche des Aufnahmefachs 24, zuverlässig abgedichtet ist und die Tinte vom Speicherkörper 3 zur Düsenplatte geleitet wird, ohne dass der Tintenfluss durch aus dem umgebenden Bereich des Aufnahmefachs 24 eindringende Luft unterbrochen werden oder umgekehrt Tinte ins Aufnahmefach 24 austreten könnte. Das Gehäuse 23 des Adapters 22 besteht ebenfalls aus Kunststoff, z.B. glasfaserverstärktem PET.The effective between the adapter 22 and the ink cartridge 1 latching connection is designed so that the sealing surface 10 presses frontally against the frame of the receiving opening 27, such that of the chamber of the ink cartridge 1 through the outlet opening 12 and the receiving opening 27 to the cavity 29 leading Ink path to the outside, ie is reliably sealed against the surrounding areas of the receiving compartment 24, and the ink is passed from the storage body 3 to the nozzle plate without interrupting the flow of ink through air entering from the surrounding area of the receiving compartment 24 or, conversely, discharging ink into the receiving compartment 24. The housing 23 of the adapter 22 is also made of plastic, e.g. glass fiber reinforced PET.

Die Tintenpatrone 1 ist sehr einfach durch eine geradlinige Bewegung in das Aufnahmefach 24 einsetzbar. Die Abdichtung des Tintenpfades ergibt sich dabei von selbst und ohne dass beim Einsetzen der Tintenpatrone 1 Reibung zwischen der Dichtung und Gegenflächen, mit denen sie zusammenwirkt, entstünde, welche das Einsetzen behindern könnte. Mühsames Einsetzen einer Dichtung auf dem Grund des Aufnahmefachs ist nicht erforderlich.The ink cartridge 1 is very easy to use by a rectilinear movement in the receiving compartment 24. The sealing of the ink path results by itself and without the insertion of the ink cartridge 1 friction between the seal and mating surfaces, with which it cooperates, would arise, which could hinder the insertion. Effortless insertion of a seal on the bottom of the receiving compartment is not required.

Die beschriebene Tintenpatrone sowie das Verschlussteil und der Adapter können vielfach abgewandelt werden. Insbesondere kann die Tintenpatrone für Farbdruck geeignet sein und mehrere, z.B. drei oder vier getrennte Kammern aufweisen, jede mit einem Speicherkörper, der mit einer Tinte einer anderen Farbe getränkt ist und einem Tntenauslass. Der Adapter muss dann entsprechend ausgebildet sein, mit mehreren Aufnahmeöffnungen und geeigneter Düsenplatte und Steuerung. Alternativ kann er mit drei oder vier Aufnahmefächern mit jeweils einer Aufnahmeöffnung versehen sein, die jeweils zur Aufnahme einer Tintenpatrone mit einer einzigen Kammer, welche Tinte einer bestimmten Farbe enthält, geeignet sind.The described ink cartridge and the closure part and the adapter can be modified in many ways. In particular, the ink cartridge may be suitable for color printing and multiple, e.g. have three or four separate chambers, each with a storage body, which is impregnated with an ink of a different color and a Tntenauslass. The adapter must then be designed accordingly, with several receiving openings and suitable nozzle plate and control. Alternatively, it may be provided with three or four storage compartments each having a receiving opening, each suitable for receiving a single-chamber ink cartridge containing ink of a particular color.
