Definitions

  • Ink cartridges used as disposable ink tanks for inkjet printers and -plotters have an ink space that is possible in the manufacture is filled with ink gas-free.
  • the ink supply one thing connected printer takes place via a hollow needle, which when inserting the Ink cartridge axially in a specially designed dome in the form of a Pipe section is pierced, which with the actual ink space in Connection is established so that ink is sucked away from the printer via the hollow needle can be.
  • the ink space with the ink storing, open-pore foam is filled, and those where the ink is free flowing in the ink room.
  • the dome is closed on the inside with a fine sieve, which acts as a filter serves, and should prevent larger particles from entering the Reach the printing system and cause faults there.
  • the outer end of the Dorns is designed to hold the hollow needle of the printer in a sealed manner. For this purpose, either a seal with a preformed opening for receiving the hollow needle provided, or an airtight membrane, the manner of a Septum can be pierced by the hollow needle.
  • This version has the special advantage that no air from outside through the Dom can get into the ink room.
  • Air bubbles can be from one certain size in particular to malfunctions in the printing system lead when they are in the cathedral, d. H. are trapped below the filter sieve, so that they can be sucked in by the hollow needle.
  • EP 0 703 083 A2 and EP 0 864 428 A2 already have vacuum filling processes have been described, in which the ink space initially with a relative high filling vacuum (more than 95%) is applied, then ink is injected and before the final, gas-tight seal of the ink space is brought back to transport vacuum, which is about 50%.
  • transport vacuum ensures that when the ink cartridge under lower atmospheric pressure or higher temperatures than is put into operation during filling, no ink is pressed outwards becomes.
  • the object of the invention is to solve the aforementioned Problem, namely to specify a procedure that is permanent The air volume in the cathedral can be minimized, even if there is the ink cartridge is no longer in a protective vacuum packaging located.
  • the invention proposes Procedure before that before evacuation to transport vacuum from outside in front of the Membrane including a defined air volume a rigid cover is tightly attached.
  • the special feature of the method according to the invention is that elastic membrane of the septum with the rigid, inelastic cover and the gas volume enclosed between them on the interior of the dome acting gas spring buffer is formed. This enables one almost complete removal of air bubbles from the cathedral, namely regardless of the ambient atmospheric conditions, as below is explained.
  • the compliance the membrane and the extent of the indentation in the dome during the evacuation of the ink space through the between the membrane and enclosed air volume of the cover according to the invention is adjustable. Regardless of the surrounding atmospheric Conditions, the elastic indentation of the membrane becomes less, the the enclosed air volume is smaller. This can in particular be avoided that when evacuating the outside of the membrane acting force is too large and the membrane either from the outside into the cathedral being pushed in or damaged, causing the ink cartridge would be equally useless.
  • the membrane itself accordingly to be stiff or resistant, namely the required, easy to pierce when inserted on the hollow needle of the printer counteract and is therefore excluded from the outset. Through the Invention resolves this conflict of objectives, so that the membrane continues to be relative thin and therefore easy to pierce, so that the im Operation required functional properties are not adversely affected.
  • An inelastic film on the membrane is preferably used as a cover appropriate. This can, for example, in front of the opening on the wall of the Doms can be attached or with the supported edge areas of the membrane be connected. This film is preferably glued or welded on.
  • the membrane When viewed from the outside, the membrane preferably has a concave indentation on. Because this indentation has a flat cover, For example, a stretched inelastic film is closed, arises an enclosed air volume of a defined size.
  • the cover for example the aforementioned inelastic film, is preferably detachably attached. This allows them to be inserted into the Inkjet printers can be easily removed by hand.
  • a vacuum for the transport vacuum of 50% or less is sufficient.
  • ink cartridge 1 In the drawings is a partial sectional view through the bottom area an ink cartridge 1 shown, the interior of the ink chamber 2nd represents. It is completely filled with ink.
  • Dome 3 In the bottom of the cartridge 1 Dome 3 in the form of a vertical pipe section.
  • a fine-pored filter sieve 4 On the upper end thereof, which is directed into the ink chamber 2, is a fine-pored filter sieve 4, for example a fine-mesh stainless steel sieve appropriate.
  • the dome 3 At the bottom, on the outer end, is the dome 3 with a pierceable Membrane 5 made of air-impermeable, elastic material, for example thermoplastic elastomer, closed. Outside on this Membrane 5 is a rigid cover 6, which is preferably made of inelastic Film is formed, tightly attached, for example welded or glued.
  • a lenticular air volume 7 Between the membrane 5, which has a concave indentation on its underside, and the inelastic film 6 is a
  • Fig. 1 shows the state after the entire ink space 2 is under beforehand a filling vacuum of about 97% filled with ink and then vented has been. The remaining 3% residual air is inside the Doms 3 collected under the filter screen 4 in the form of air bubbles 8. Because of Their surface tension prevents these air bubbles 8 from Filter screen 4 to get up into the ink chamber 2. There is therefore the Danger that in the operating state of a - shown here in dashed lines - Hollow needle 9 would be sucked in and lead to impairments in printing could.
  • Fig. 2 shows a snapshot when the Ink space 2 with the transport vacuum. Due to the negative pressure expands the air volume 7, the membrane 5 being formed inside the dome 3 becomes. The rigid cover 6 remains essentially undeformed. As a result of the membrane 5 being formed in the dome 3 Liquid displacement displaces the ink enclosed in it. The air bubbles 8 are through the filter 4 in the ink chamber 2 pressed. There they climb up and gather up in ink room 2, where they are suctioned off or remain.
  • FIG shown final state in which - as shown - no residual air in the dome 3 remains, or is at least reduced to a remainder, which for the proper operation of a connected inkjet printer is harmless.
