Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the ink cartridge 1 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.
  • an ink outlet 6 is provided at the bottom of the housing 2.
  • the housing has an opening 7 (FIG. Fig. 5 ), in which a seal 8 is inserted.
  • 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.
  • 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.
  • 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.
  • the housing 2 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.
  • the ink cartridge 1 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 Ausbloodung 17 des Geotrouses 19a anorg.
  • 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.
  • the closure member 17 consists of a relatively rigid elastic plastic, eg polypropylene.
  • 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.
  • the housing 23 carries a nozzle plate (not shown) for the controlled release of ink droplets. Nozzle plates and their control are well known.
  • 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.
  • 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.
  • 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.
  • the ink cartridge and the closure part and the adapter can be modified in many ways.
  • 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.
  • 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.
