Definitions

  • the present invention relates to a cartridge refill device.
  • Inkjet printing devices known in the art use a small ink cartridge to deliver drops of liquid ink to form a visible image.
  • An inkjet cartridge known in the art manufactured and sold by Hewlett Packard, is comprised of a cartridge body for holding the ink and internally thereof, a pair of spring loaded air inflatable sacs in communication through a wall of the cartridge with ambient air.
  • a wall of the cartridge is provided with a print head formed of inkjet orifices which deliver ink during operation to the printing device and a bubbler valve which controls the outflow of ink in conjunction with the inflatable air sacs.
  • the bubbler valve in the Hewlett Packard cartridge comprises a ball sealed in a spiral passageway. It is designed so that the viscosity of the ink which usually coats it will act as a vacuum limiter. If the vacuum exceeds a predetermined value, air will be pulled past the ball and into the cartridge chamber.
  • a refill jig for an ink cartridge having a print head formed of inkjet orifices, a bubbler valve, spring loaded internally mounted air sacs and a passageway for ambient air to the air sacs
  • the jig comprising a support frame for mounting the cartridge in a refill position, a refill ink reservoir mounted on the support frame, valve means on the frame operable when the cartridge is in the refill position to release ink from the ink reservoir through the bubbler valve to refill the cartridge, and an intermittently operable pressurised air supply on the frame for inflating the air sacs of the cartridge in the refill position through the passageway for ambient air to the air sacs cyclically to inflate the air sacs such that with the inkjet orifices closed, air is evacuated from the cartridge through the bubbler valve and valve means into the ink reservoir until the cartridge is filled.
  • a refill jig for an ink cartridge having a print head formed of inkjet orifices, a bubbler valve, spring loaded internally mounted air sacs and a passageway for ambient air to the air sacs, the jig comprising a support frame for mounting the cartridge in a refill position, and an intermittently operable pressurised air supply for inflating the air sacs of the cartridge in the refill position through the passageway for ambient air to the airs sacs cyclically to inflate the air sacs such that with the inkjet orifices closed, air is evacuated from the cartridge through the bubbler valve to allow the cartridge to be filled with ink.
  • valve means for a refill apparatus for an ink cartridge having a print head formed of inkjet orifices, a bubbler valve, spring loaded internally mounted air sacs and a passageway for ambient air to the air sacs, the valve means comprising a passageway which selectively allows ink to flow from a reservoir into the bubbler valve, the passage opening to an outlet in the form of an annular channel arranged to be adjacent, in use, to the bubbler valve.
  • Figure 1 is a cross sectional view of the refill jig according to the invention, mounting a cartridge
  • Figure 2 is a view of the refill jig similar to Figure 1 in the refill position;
  • "igure 3 is a view of a refill sachet for use with the jig of Figures 1 and 2;
  • Figure 4 is a cross sectional view through a feed valve of the sachet of Figure 3 shown mounted to the refill jig in Figures 1 and 2;
  • Figure 5 is a cross sectional view of the same nozzle of the sachet of Figure 3 with the feed valve in the refill position of the jig shown in Figure 2;
  • Figure 6 is a cross-sectional view through a feed valve according to a further embodiment of the invention in a pre-refill position
  • Figure 7 is a cross-sectional view through the valve of Figure 6 in a refill position
  • Figure 8 is a view showing how the valve of Figure 6 provides ink to a cartridge
  • Figure 9 is a cross-sectional view through a feed valve according to a yet further embodiment of the invention.
  • Figure 10 is a cross-sectional view through the valve of Figure 9 in a refill position.
  • the refill jig shown in Figures 1 and 2 comprises a housing 1 made of a thin resilient plastics material, for mounting a Hewlett Packard inkjet cartridge
  • the top of the cartridge is provided with a print head 5 having inkjet orifices (not seen) and an air vent 6 in the form of a bubbler valve, not shown in detail, but which may comprise an aperture opening into a spiral passageway sealed at the end opening into the cartridge chamber with a control ball.
  • the housing 1 is articulated at 7 to a support base frame 8 also made of a thin resilient plastics material, provided with an hermetically sealed depressible dome 9 which supplies air when depressed through an air supply tube 10, to the inlet 4 to the air sacs 3 when the jig is in the refill position shown in Figure 2.
  • a U-shaped recess 11 is formed in the top of the housing 1 for engagement with spaced rimmed flanges 12 on the nozzle 13 of a refill sachet 14 shown in Figure 3.
  • the nozzle 13 of the sachet 14 is provided with an actuable refill valve 15 as shown in greater detail in
  • the valve 15 is formed of a compressible material provided with an L-shaped internal passageway 16.
  • the body 17 of the valve is bobbin shaped and the walls of the nozzle 13 are configured to occupy the space between the upper and lower flanges 18,19 of the bobbin shaped body 17.
  • the passageway 16 is sealed against the wall of the configured portion of nozzle 13 as shown in Figure 4 to prevent loss of inkjet fluid.
  • valve body 17 and the top of the refill cartridge 2 compresses the lower flange 19 of the bobbin shaped valve body 17, raising the upper part of the valve body 17 and allowing the ink to flow through the passageway 16 from the refill sachet 14 into the chamber of the cartridge 2.
  • a closure member 20 mounted on the inside of the wall of the housing tightly engages the inkjet orifices of the print head 5 to close them.
  • the jig is maintained in the refill position by means c a hook shaped resilient catch 21 engaging a slot 22 in the support base 8.
  • the catch has a release button 23.
  • the release button 23, in the jig refill position, is hidden behind the pressure supply dome 9 so that it is generally inaccessible to the user until the dome 9 is depressed.
  • the user depresses the dome 9 which forces air into the air sacs 3, normally held flat under their spring loading, through the air supply tube 10.
  • the cartridge 2 is thus pressurised, forcing air into the bubbler valve 6 and through the open valve 15 in the nozzle 13 of the sachet 14. Air then bubbles through the ink to the top of the sachet 14.
  • the capacity of the pressure supply dome is matched to that of the two air sacs 3 such that under thumb pressure the air sacs 3 inflate short of bursting.
  • the cubic capacity is approximately 20 cc.
  • the refill jig of the present invention is designed to achieve refilling, but without subsequent ink leakage.
  • the user is not able to operate the main catch 21,22,23 to open the jig, because access is blocked by the pressure supply dome 9. Access is only possible by pressing the dome 9 and simultaneously pressing the catch button 23, thus ensuring that the air sacs are partially inflated at the moment when the valve 15 in the sachet 14 is closed.
  • Figure 1 shows the position when the dome is depressed, after filling a cartridge, to release catch 10.
  • FIGS. 6 to 8 show a further embodiment of the invention and illustrates more clearly the manner in which the valve may function.
  • a valve body 61 sits within a nozzle 62 as before.
  • Valve body 61 includes an L-shaped passage 63 which is, in the closed position, sealed against the wall of the nozzle to present loss of inkjet fluid.
  • Figure 7 shows how in the cartridge refill position, the lower part of valve 61 is compressed, raising the upper part of the valve and allowing ink to flow through passageway 63 from the refill sachet into the chamber of a cartridge.
  • the valve of Figures 1 to 5 works in a similar way.
  • the L-shaped passage 63 opens into an annular channel 64 in the base of the valve body 61.
  • the position of the fill hole (bubbler valve) in the surface of a cartridge can vary, either by variations unit by unit, or by design.
  • the hole position of a cartridge was altered by Hewlett Packard by 3mm.
  • the ball of the bubbler valve was also omitted.
  • the annular fill channel of the embodiment of Figures 6 to 8 enables any fill hole, which at least partially lies within the region defined by the annular channel, to be filled. This is shown in Figure 8, which shows the top of a cartridge.
  • Two alternative fill hole positions A and B are shown which both 'overlap' the extent of annular channel 64.
  • Ink from passage 63 flows into channel 64, from where it can pass into hole A or hole B (only one of these will, of course, be provided on any cartridge), or indeed into a hole position anywhere else under annulus 64.
  • the figure also shows the inkjets 65 of the cartridge.
  • Figures 9 and 10 show an alternative valve system which also comprises a compressible member 65.
  • this embodiment further comprises a separate non-compressible sealing piece 66, incorporating a lengthwise groove 67.
  • the compressible member 65 is relaxed (ie not compressed) and the head 68 of the sealing piece 66 firmly seals against the upper part of member 63, preventing ink flow through the valve.
