- An ink cartridge according to the invention has a through opening in the first ink chamber, which connects the first ink chamber to an ink supply nozzle, which contains a movably arranged porous compressible element.
- each of these ink supply nozzles contains a porous and compressible element.
- any porous component is suitable as a porous and compressible element, which can be compressed in at least one spatial direction, preferably in the direction of the longitudinal axis of the ink supply nozzle directed towards the ink cartridge, under the conditions prevailing in the ink supply nozzle when the ink cartridge is applied to a recording head.

- the present invention relates to an ink cartridge as described above, which is characterized in that the ink supply nozzle according to (b) is flush with the interior of the ink chamber according to (a).
- the ink supply nozzle contains a porous and compressible element which is arranged movably in the ink supply nozzle. It is not necessary for this porous element to be located completely in the ink supply nozzle. Rather, it is also possible that only a part of the porous element is in the ink supply nozzle. It is also possible that the porous element is completely in the ink supply nozzle before the ink cartridge is attached to the ink supply needle, while only a part of the porous element is enclosed by the ink supply nozzle after the application.
- the ink supply nozzle can contain one or more further ink-conducting elements which are porous and / or compressible or are otherwise ink-conducting. If two or more porous and compressible elements are contained in the ink supply nozzle, each of these elements, depending on the geometry of the ink supply nozzle, can have a different before having geometry.
- the ink cartridge according to the invention preferably contains a single porous, compressible and preferably movably arranged element.
- the porous element in the ink supply nozzle also particularly preferably has a cylindrical shape.
- the diameter of the porous element is selected so that the porous element fills the ink supply nozzle and substantially completely touches the inner surface of the ink supply nozzle, but the mobility of the porous element in the ink supply nozzle should be ensured.
- the porous element does not completely fill the ink supply nozzle and only partially or not touches the inner surface of the ink supply nozzle.
- the ink cartridge according to the invention is suitable for application to recording heads which have an ink supply needle.
- An “ink supply needle” is understood to mean a component of the recording head which ensures the supply of ink from the ink cartridge to the recording head.
- An ink supply needle as required for an ink cartridge according to the present invention, has a diameter, which is smaller than the diameter of the ink supply nozzle of the ink cartridge, preferably the diameter of a suitable ink supply needle is approximately 0.99 to 0.01 times, for example 0.9 to 0.02 times or 0.8 to 0 , 05 times or 0.5 to 0.1 times the diameter of the ink supply nozzle.
- the geometry of the porous element in the ink supply nozzle is such that, after the ink cartridge has been attached to the recording head, it is in one end contact with the first porous element of the first ink chamber and the other end with the ink supply needle.
- the porous element in the ink supply nozzle can already be in contact with the porous element of the first ink chamber before the ink cartridge is attached to the ink supply needle, or only by the supply needle applied pressure on the porous element in the ink supply nozzle with the porous element of the first ink chamber in pressure contact.
- the geometry of the latter is such that, after the ink cartridge has been applied to the ink supply needle, they are in contact with one another on the one hand, and on the other hand at least one of the porous elements with the ink supply needle and another of the porous elements Elements is in contact with the porous element of the first ink chamber and so the ink flow from the first ink chamber to the ink supply needle can be established.
- the present invention also relates to an ink cartridge as described above, which is characterized in that the at least one second porous element after the ink cartridge has been mounted on the recording head in contact with the at least one first porous element in the ink chamber and in contact with the inks - feed needle is standing.
- the materials from which the respective porous elements are made in the respective ink supply nozzle can also be different from one another. Differences can exist, for example, in the material itself or, for example, in the pore size. It only has to be ensured here that when there is pressure contact between the ink supply needle and the porous element of the ink supply nozzle and between the porous element of the ink supply nozzle and the porous element of the ink chamber, there is sufficient ink flow from the porous element of the ink chamber to the porous element of the ink supply nozzle and from there to the ink supply needle can be manufactured.
- the ink supply needle can basically have any shape as long as the above limits of the diameter are maintained.
- the tip of the ink supply needle can essentially be cylindrical, tapered, or a spherical half-shell, for example, and can have one or more openings for receiving ink.
- a suitable ink supply needle is designed, for example, in such a way that it has a tapered end and has a plurality of through holes in the surface at the tip, which come into contact with the porous element when the ink supply needle is in contact with the ink and the pores of the porous element are filled allow the ink to flow into an ink-carrying channel formed inside the ink supply needle.
- the through opening which connects the ink supply nozzle to the ink chamber, is preferably designed such that its geometry matches the internal geometry of the ink supply nozzle.
- this through opening is therefore essentially circular and has a diameter which corresponds to the inside diameter of the nozzle and allows the porous element of the ink supply nozzle to pass into the ink chamber.
- the porous element is elastically deformed and the capillary forces which occur in the deformed region of the porous element cause a preferred direction for the ink flow, which the ink into the deformed region and thus exactly to the through hole with the tip of the ink supply needle.
- the porous element which is movably arranged, is not only deformed from the tip of the needle, but also in the direction of the needle first ink chamber shifted, whereby a pressure contact between the porous element of the ink supply nozzle and the porous element contained in the ink chamber is made.
- the area in which the porous element of the ink chamber is brought into pressure contact with the porous element of the ink supply nozzle is deformed in such a way that the capillary forces occurring in the porous and compressible materials cause a preferred direction of the ink flow from the porous element of the ink chamber to the porous element of the ink supply port is effected.
- the at least one porous element which is movably arranged in the ink supply nozzle has a lower compressibility than the at least one porous element of the ink chamber. This ensures that the pores of the porous element of the ink chamber are reduced exactly in the area in which the porous element of the ink supply nozzle is in contact with the porous element of the ink chamber, and that the capillary forces described above occur in this area.
- the ink flow from the ink chamber into the ink supply nozzle is efficiently induced by the pressure contact of two porous and differently compressible elements.
- the present invention therefore also relates to the use of two porous elements, the ink being stored in one of the porous elements and this ink being conveyed to an ink supply needle via the other porous element.
- the two porous elements are in pressure contact with one another.
- the porous element in which the ink is stored has a greater compressibility than the porous element via which the ink is guided to the ink supply needle. The latter element is again in pressure contact with the ink supply needle when the ink is supplied.
- the present invention also relates to the use of two porous elements of different compressibility for supplying ink from the porous element greater compressibility via the porous member of lower compressibility to an ink supply needle of a recording head in contact with the porous member of lower compressibility.
- the material from which the porous element is made in the ink chamber can essentially be chosen freely and only has to meet the requirements described above.
- Porous, compressible materials are preferably used, which essentially correspond to those already described in the description of the porous and compressible element in the ink supply nozzle.
- the compressible element in the ink supply nozzle preferably has a lower compressibility or a smaller pore size or both
- the present invention also relates to an ink cartridge, as described above, which is characterized in that the at least one second porous element has a lower compressibility than the at least one first porous element.
- the present invention accordingly also relates to a method for supplying ink from an ink cartridge, comprising
- the porous member in the ink supply port which at least partially contacts the inside thereof, is moved toward the ink chamber, the outside of the porous member wiping along the inside of the ink supply port. After the outside of the porous member also has pores, ink adhered to the inside of the ink supply port is absorbed into the porous member and can be supplied to the ink supply needle.
- a fundamental advantage that the ink cartridge according to the invention offers is the combined effect of the porous element in the ink supply nozzle.
- the built-up drain contacts when attached to the ink supply needle enable the precisely directed ink flow from the ink supply chamber to the ink supply needle, which is induced by capillary effects.
- the filter effect is also to be emphasized, which makes the fixed and thus complex attachment of a filter superfluous.
- due to the complete porous structure extending to the edge regions of the element residual ink is fed from these edge regions to the ink supply needle.
- the porous element in the ink supply nozzle is accordingly a multifunctional element that combines the most diverse advantages in the simplest form of execution.
- the ink supply nozzle at the end facing the recording head contains a sealing element which is adapted to the geometry of the ink supply nozzle.
- the sealing element is therefore also essentially cylindrical, the diameter of the sealing element being selected such that the desired sealing of the ink supply nozzle against the recording head is achieved.
- the sealing element After the ink cartridge has to be brought into pressure contact with the porous element of the ink supply nozzle when the ink cartridge is applied to the ink supply needle, the sealing element has a recess through which the ink supply needle can be inserted into the nozzle.
- This recess can be adapted to the geometry of the ink feed needle. It is also conceivable to choose the material of the sealing ring so that the sealing element adapts to the geometry of the needle due to its flexibility and thus ensures the required sealing.
- the above-described recess can be closed in a suitable manner, for example by a thin film, before the ink cartridge is applied to the ink feed needle and can be pierced by the ink feed needle when it is applied to the recording head.
- the recess of the sealing element is particularly preferably circular.
- the diameter of the circular recess is preferably selected so that it is slightly smaller than the outer diameter of the ink supply needle and thus provides an effective seal between the interior of the ink cartridge and the surroundings.
- the sealing of the interior of the ink cartridge is therefore preferably effected by means of a sealing element which lies tightly against the outside of the ink supply needle.
- the sealing element mentioned above is supplemented by one or more further sealing elements.
- Such further sealing elements can be located, for example, on the end of the ink supply nozzle directed towards the recording head or on the recording head itself. Accordingly, the present invention also relates to an ink cartridge, as described above, which is characterized in that the ink supply nozzle has a sealing element at its end facing the recording head.
- the substantially circular recess in the annular sealing element is designed such that it tapers conically from its side facing the recording head, the smallest diameter of the hole achieved by the taper being slightly smaller, as described above, as described above than the outside diameter of the ink supply needle. In addition to the aspect of saving material, this leads to guidance of the ink supply needle through the sealing element.
- the sealing element and the porous element of the ink supply nozzle are spatially separated from one another, thereby preventing direct contact between the two elements and preventing the sealing element from moving when the ink supply needle is inserted in the direction of the first ink chamber.
- this spatial separation is achieved by at least one holding element which is arranged between the sealing element and the porous element.
- the design of the holding elements is essentially not subject to any restrictions. It is only necessary to implement the spatial separation described and also to enable the ink supply needle to be brought into sealing contact with the porous element of the ink supply nozzle through the sealing element and separating element.
- the ink cartridge according to the invention preferably has a single holding element in the ink supply nozzle, which is designed in the form of a ring.
- the present invention also relates to an ink cartridge, as described above, which is characterized in that the annular sealing element is spatially separated from the second porous element by at least one holding element formed on the inside of the ink supply nozzle.

- the first embodiment is achieved, for example, in such a way that the porous element in the ink supply nozzle is longer than the distance between the separating burr in the ink supply nozzle and the porous element in the ink chamber.
- the second embodiment can be formed in that the length of the porous element in the ink supply nozzle is less than or equal to the distance between the separating burr and the porous element of the ink chamber, but is chosen so large that the contact between the ink supply needle and the porous element causes the latter to contact the porous element the ink chamber is brought into contact.
- the length of the porous element as a function of the length of the part of the ink supply needle which projects into the interior of the ink supply nozzle after the ink cartridge has been applied to the ink supply needle, so that the above-described Ink flow generated by capillary forces from the porous element of the ink chamber to the porous element of the ink supply nozzle only begins when the ink supply needle is in contact with the porous element of the ink supply by applying the cartridge. Is brought nozzle, thereby pushing the porous element of the ink supply nozzle from the ink supply needle in the direction of the porous element of the ink chamber and thus bringing it into contact with it.
- the interior of the ink chamber can essentially be configured as desired.
- the bottom of the ink chamber, on which the ink supply nozzle is molded and connected to the ink chamber via the through opening is at least partially non-planar.
- a convex, trough-shaped design of the base it is achieved, among other things, that the ink tends to collect in the center of the ink chamber base and is thus closer to the passage opening to the ink supply nozzle. Particularly when the ink supply in the ink chamber is exhausted, this avoids ink that would otherwise collect on the outer edges in the interior of the ink chambers and represent unusable residual ink.
- the present invention also relates to an ink cartridge, as described above, which is characterized in that the bottom of the ink chamber is trough-shaped.
- the geometry of the porous element in the ink chamber can be adapted to the non-flat ink chamber floor.
- a porous element which is concave on its underside facing the ink chamber base can therefore be used.

- This closure element is preferably designed such that it borders the edges of the seals the walls of the ink chamber with respect to the outflow of ink from the ink chamber.
- At least one reinforcing element can, for example, be molded onto the underside of the closure element facing the ink chamber.
- the ink cartridge comprises two or more first ink chambers
- a single closure element is preferably used, which seals all ink chambers at the same time.
- the closure element (lid) of an ink cartridge according to the invention has one or more through openings which enable gas and / or mass exchange with the surroundings.
- each of the through openings of the closure element can be closed with at least one sealing element.
- the sealing element can, for example, be an element attached to the outside of the closure element.
- the sealing element is preferably attached externally to the respective opening so that it can be easily removed by the end user before the ink cartridge is started up.
- the ink cartridge according to the invention also preferably has at least one support element formed on the underside of the ink chamber base facing the recording head.
- This support element is used, among other things, to ensure that the ink cartridge is supported as advantageously as possible on the recording head.
