Definitions

  • the invention relates to an ink cartridge according to the preamble of claim 1.
  • ink cartridges are well known. It is in this regard only on the example EP 1 481 809 A2 .
  • the ink cartridge comprises a negative pressure generating member which sufficiently restrains the ink so that the ink cartridge does not leak at standstill.
  • the negative pressure generating element consists of a sponge or fibrous material, which is disposed within a so-called ink storage chamber immediately before an outlet to the supply port of the ink jet printer.
  • the present invention is therefore to provide an ink cartridge of the type mentioned, which is designed so that an ink supply by bubbles, which form when filling the ink cartridge in different sizes, is not interrupted, even then when larger bubbles form.
  • the ink supply channel is preferably in fluid communication with the ink storage chamber over its entire length, i. is open at its top. If an ink storage element in the form of a sponge or fiber element is located in the ink storage chamber, this immediately adjoins the open top side of the ink supply channel. Any air bubbles will then accumulate at the top of the ink supply channel or at the bottom of the ink storage element. Below these bubbles, the ink supply of the connection piece or the ink discharge opening is maintained.
  • the cross-section of the ink supply channel has a width to depth ratio of less than 1, this ratio decreasing towards the ink discharge opening.
  • the width of the ink supply channel at its top is preferably constant and is 1.0 to 3.0 mm, the width decreasing in the direction of the depth.
  • the cross section of the ink supply channel is formed approximately V-shaped.
  • the ink supply channel is formed so that in use of the ink cartridge which is located in the ink supply channel ink gravitationally flows to the connection piece or to the ink removal opening, an almost complete emptying of the ink cartridge, in particular a refilled ink cartridge is guaranteed.
  • this measure is achieved by the fact that the bottom of the ink supply channel in the direction of the connection piece or to the ink removal opening drops out.
  • the width is preferably between about 0.1 to 2.0 mm, which width decreases with increasing depth of the ink supply channel, in particular decreases continuously.
  • the above measure is inevitably achieved when the angle between the two side walls of the ink supply channel remains constant over the length, but the bottom of the ink supply channel drops toward the port or ink discharge port.
  • an ink cartridge 10 is shown in various views and sections.
  • This ink cartridge has a plastic-made housing 11 defining an ink storage chamber 12, wherein in the ink storage chamber 12 a Ink storage element of sponge or fibrous material is located.
  • a connecting piece 15 which defines an ink removal opening 16, via which a fluid connection between the ink storage chamber 12 and a provided on the ink jet printer supply connection can be produced.
  • the cartridge 10 can also be formed with two chambers which are divided by a partition, wherein the chambers are fluidly connected to each other by a passage formed at the lower end of the partition wall.
  • one chamber is a memory of sponge or fibers corresponding to the ink storage element 13, while the other chamber is filled with ink. Also in this embodiment, the connecting piece of the chamber is associated with ink storage element. Since this is a known construction, no further description is required here.
  • the connecting piece 15 a the same over a predetermined height, here approximately half the height of the same extending ink supply channel 17 upstream, in particular, which is formed in the bottom 14 of the ink cartridge 10.
  • This ink supply channel 17 is arranged sunk relative to the lower peripheral edge 18 of the housing 11 of the ink cartridge limiting end and side walls, in particular the Figures 2 . 4 and 5 very good.
  • the ink supply channel 17 7 extends over about half the floor length. Furthermore, the Fig. 2 can be seen very well that the ink supply channel 17 is formed so that in use of the ink cartridge, that is, in a position in which the bottom 14 is below, which is located in the ink supply channel 17 ink gravitationally flows to the connecting piece 15 and ink discharge port 16 out , Concretely, the bottom 19 of the ink supply channel 17 drops toward port 15 and ink discharge port 16, respectively.
  • the cross section of the ink supply channel 17 has a ratio of width "B" to depth "T" of less than 1 (B: T ⁇ 1), this ratio towards the port 15 and the ink discharge port 16 out reduced.
  • B width of the ink supply channel 17
  • the width "B" is approximately constant over the length and is about. 1.0 to 3.0 mm.
  • the width thereof is about 0.1, in particular about 0.3 to 2.0 mm, said width decreases with increasing depth "T" of the ink supply channel 17, in particular decreases continuously.
  • the ink discharge opening 16 is associated with a valve ball 21 elastically biased by a helical compression spring 20, by which the ink discharge opening 1 is kept closed when the cartridge is not in use. Only in use, the valve ball 21 is lifted from the ink removal port 16 by a plunger-type supply port of the ink jet printer, so that the desired fluid connection or ink connection between the cartridge and ink jet printer is made.
  • the ink removal opening 16 is also additionally closed on the outside by a film 22 which is pierced before the first use, so that the ink removal opening is accessible from the outside. Again, it is an already known measure.
