Description
~he present invention rela-tes to an ink cartridge for use in an ink liquid supply system of an ink jet printer and to an ink liquid supply system including such a car-tridge.
Generally, an ink cartridge is employed in an ink liquid supply system for an ink jet prin-ter. ~ conventional ink liquid supply system includes an upright needle which is inserted into a seal member formed in the ink cartridge when the ink cartridge is attached to the ink liquid supply system.
If the ink cartridge is removed from the ink liquid supply system while some o~ the ink liquid is still contain-ed in -the ink cartridge, there is a possibility that the ink liquid may drip through the hole formed by the needle in the seal member. The ink liquid dripping from -the ink cartridge may damage the insulation of the ink jet printer.
A satisfactory rubber seal to prevent the above~mentioned ink liquid dropping has nok yet been developed.
Accordingly, an object of the present invention is to provide an ink cartridge for use in an ink liquid sup-ply system and which does not allow ink liquid to drip from the cartridge even ~hough the ink cartridge is removed from the remainder of an in~ liquid supply system with some ink liquid still contained in the ink car~ridge.
~5 The present invention provides an ink cartridge ~or use in an ink supply sys-tem of an ink jet printer, the ink cartridge comprising, the car-tridge having a bo-ttom wall, an opening extending through the bottom wall, means for seal-ing the opening, an ink liquid absorbing member associa-ted with the seal for absorbing ink liquid leakage from the seal upon piercing of the seal by an ink feed member of the sys-tem and subse~uent removal of the in~ feed member from the seal .
The cartridge may have a cylindrical projection depending from the bottom wall and defining an ink liquid passage communicating with the openingl and a cap member engageable with the projection with the seal means and the liquid absorbing member interposed between the cap member ,, ~ ............... . ...
~ 2 --and the projection, the cap member being formed with an aperture for alignment with the passage. Preferably, the projection and the cap member are formed with mutually threadedly interengageable threaded portions.
The present invention further provides an ink liquid supply system for an ink jet system printer the sys-tem including an ink cartridge for holding a supply of ink liquid and at least one ink intake needle for providing communication for the ink liquid between the ink cartridge and -the remainder of the ink liquid supply system, the ink cartridge comprising, a bottom wall provided wi-th an open-ing formed at a position corresponding to the ink intake needle, a seal member disposed at the opening so as to seal the opening, and an ink liquid absorbing member associated with the seal member, the ink intake needle being inserted through the inlc liquid absorbing member and the seal member when the ink cartridge is connected in the ink liquid supply system.
The present invention will be better understood from the detailed description of an embodiment thereof given hereinbelow and illustrated in the accompanyi.ng drawings which are given by way of illustration only, and thus are not limitative of the present invention. Accordingly, it should be ~mderstood that the detailed description and spe-cific examples given below, while indicating preferred em-bod.imen-ts of the inven-tion, are given by way of illustration only, since various changes and modifications within the spi.rit and scope of the invention will become apparent to those slcilled in the art from this detailed descrip-tion.
In the drawings:-Figure 1 is a block diagram of an ink liquid sup-ply system in an ink jet printer of the charge amplitude controlling type, provided with an ink cartridge embodying the present inven-tion;
Figure 2 is a perspective view of the ink cart-ridge embodiment of Figure l;
Figure 3 is a partially sectional view of a part of the ink cartridge of Figure 2, showing a condition in which the ink cartridge is secured to the ink liquid supply system; and Figure 4 is a perspective view of a cap portion included in the ink cartridge of Figure 2.
An ink liquid supply sys-tem for an ink jet printer of the charge amplitude controlling type includes an ink cartridge 10 removably secured in the ink liquid supply sys-tem. More specifically, the ink liquid supply system in-cludes an ink intake needle 12 for introducing ink liquid 10 14 from the ink cartridge 10 into an ink supply conduit 16, and an ink discharge needle 18 for discharging recycled ink liquid into the ink cartridge 10. The ink intake needle 12 and the ink discharge needle 18 are inserted into seal portions of the ink cartridge 10 when the ink cartridge 10 is secured to the ink liquid supply system.
An example of the ink liquid supply system of the above-mentioned type is disclosed in the Applicant's co-pending Canadian patent application No. 432,323 entitled "BUBBLE REMOVAL IN AN INK LIQUID SUPPLY SYSTE~ OF AN INK
20 JET SYSTE~5 PRINTER" filed July 13, 1983.
The ink liquid introduced from the ink cartridge 10 is supplied to a subtank 20 via the ink supply conduit 16. A constant flow rate pump 2~ pumps the ink liquid from the subtank 20 via an ink inlet valve ~4. The constant flow rate pump 22 supplies the ink liquid a-t a constant flow rate to an accumulator 26 through an ink outlet valve 280 The accumulator 26 functions to stabiliæe the static pressure of the ink liquid developed from the constant flow rate pump 22.
The thus-stabilized ink liquid is supplied from the accumulator 26 to a printer head 30 via an electromagne-tic cross-valve 32. As is well known in -the art, the printer head 30 includes a nozzle to which an electromechanical transducer (pi~zo vibrator) is attached in order -to emit ink droplets at a given fre~uency. The printer head 30 fur-ther includes a charging tunnel for charging the ink droplets in accordance with a print information signal. The charged ink droplets are deflected while they pass between a pair ~22~
of deflection electrodes which are also included in the printer head 30. The ink droplets not contributing to the actual printing operation are no~ charged nor deflected, and are directed to a beam gutter 34. The ink li~uid collected by the beam gutter 34 is returned to the ink cartridge 10 via a return conduit 36. The ink liquid in-troduced into -the return conduit 36 is fed to the ink dis-charge needle 18 by means of a suction pump 38. Valves 40 and 42 are associated with -the suction pump 38 to ensure the return of the ink liquid operation.
The ink cartridge 10 is provided with a cylindri-cally-shaped projecting opening 44 formed in the upper sur-face thereof. The outer periphery of the projecting opening 44 is provided with a threaded portion to which a cap 46 15 i8 engaged. q'he cap 46 is removed from the projecting open-in~ ~ wh~n new ink li~uid is lntroduced into the ink cart-ridge 10. The cap 46 includes handling ribs 48, and flat plate portions 50 which ensure tight connection between the cap 46 and the upper surface of the ink cartridge 10. When the ink jet system printer is placed in an operating condi-tion, the cap 46 is slightly loosened so as to ensure that the ink liquid 14 is contained in the ink cartridge 10 at atmospheric pressure.
Communication~seal portions 52 and 54 are formed on the bottom wall of the ink cartridge 10 throu~h which the in]c intake needle 12 and the ink discharge needle 54 are inserted, respectively. The communication/seal portions 52 and 54 each have the same construction.
The communication/seal portion 52 or 54 includes a cylindrically-shaped projection 56 which has an ink liquid passage 58 ~ormed through the center of the cylindrically-shaped projection 56. A threaded portion 60 is formed on the outer periphery of cylindrically-shaped projection 56.
A seal cap 62 has a threaded portion formed on an inner cy-lindrical surface thereof, the threaded portion being engag-ed with the threaded portion 60 of the cylindrically shaped projection 56. The seal cap 62 is provided with a communi-cation opening ~4 which is formed at the center of the bottom wall of the seal cap 62. A seal rubber 66 for sealing the ink liquid passage 58 formed in the cylindrically-shaped projection 5~, and an ink liquid absorbing pad 68 made of sponge are disposed between the cylindrically~shaped projec-tion 5~ and the seal cap 62.
When the thus-constructed ink cartridge 10 is se-cured to the ink liquid supply system, the ink intake needle 12 is inserted through the ink liquid absorbing pad 6B and the seal rubber 66 via the communication opening 64. The tip end of the ink intake needle 12 reaches the ink liquid 14 disposed in the ink cartridge 10 so as to intake the ink liquid 14 from the ink cartridge 10 into the ink liquid sup-ply system. In a same manner, the ink discharge needle 18 is inserted through the ink liquid absorbing pad 68 and the seal rubber 66 so that the ink liquid developed from the suction pump 38 is introduced into the ink cartridge 10.
When desired, the ink cartridge 10 is removed from the ink liquid supply system. At this moment, the seal rub-bers 66 and the ink liquid absorb ng pads 68 are removed Erom the ink intake needle 12 and the ink discharge needle 18. If any of the ink liquid 14 remains in the ink cartridge 10, the ink liquid may flow through the holes formed by the ink intake needle 12 and the ink discharge needle 18 in the seal rubbers 66. However, the thus-leaked ink liquid is absorbed by the ink liquid absorbing pads 68, thereby pre-ven-ting the ink liquid from dripping onto the ink jet system printer. Furthermore, the ink liquid absorbing pads 68 func-tion to wipe off ink liquid attached to the ink intake needle 12 and the ink discharge needle 18 when the ink cartridge 10 is removed from the ink liquid supply system.
An embodiment of the invention being thus describ-ed, it will be obvious that the invention may be varied in many ways. Such variations are not to be regarded as a de-parture from the spirit and scope of the inven-tion, and all 35 such modifica-tions are intended to be included within the scope of the following claims.

The present invention will be better understood from the detailed description of an embodiment thereof given hereinbelow and illustrated in the accompanyi.ng drawings which are given by way of illustration only, and thus are not limitative of the present invention. Accordingly, it should be ~mderstood that the detailed description and spe-cific examples given below, while indicating preferred em-bod.imen-ts of the inven-tion, are given by way of illustration only, since various changes and modifications within the spi.rit and scope of the invention will become apparent to those slcilled in the art from this detailed descrip-tion.
In the drawings:-Figure 1 is a block diagram of an ink liquid sup-ply system in an ink jet printer of the charge amplitude controlling type, provided with an ink cartridge embodying the present inven-tion;
Figure 2 is a perspective view of the ink cart-ridge embodiment of Figure l;
Figure 3 is a partially sectional view of a part of the ink cartridge of Figure 2, showing a condition in which the ink cartridge is secured to the ink liquid supply system; and Figure 4 is a perspective view of a cap portion included in the ink cartridge of Figure 2.
An ink liquid supply sys-tem for an ink jet printer of the charge amplitude controlling type includes an ink cartridge 10 removably secured in the ink liquid supply sys-tem. More specifically, the ink liquid supply system in-cludes an ink intake needle 12 for introducing ink liquid 10 14 from the ink cartridge 10 into an ink supply conduit 16, and an ink discharge needle 18 for discharging recycled ink liquid into the ink cartridge 10. The ink intake needle 12 and the ink discharge needle 18 are inserted into seal portions of the ink cartridge 10 when the ink cartridge 10 is secured to the ink liquid supply system.
An example of the ink liquid supply system of the above-mentioned type is disclosed in the Applicant's co-pending Canadian patent application No. 432,323 entitled "BUBBLE REMOVAL IN AN INK LIQUID SUPPLY SYSTE~ OF AN INK
20 JET SYSTE~5 PRINTER" filed July 13, 1983.
The ink liquid introduced from the ink cartridge 10 is supplied to a subtank 20 via the ink supply conduit 16. A constant flow rate pump 2~ pumps the ink liquid from the subtank 20 via an ink inlet valve ~4. The constant flow rate pump 22 supplies the ink liquid a-t a constant flow rate to an accumulator 26 through an ink outlet valve 280 The accumulator 26 functions to stabiliæe the static pressure of the ink liquid developed from the constant flow rate pump 22.
The thus-stabilized ink liquid is supplied from the accumulator 26 to a printer head 30 via an electromagne-tic cross-valve 32. As is well known in -the art, the printer head 30 includes a nozzle to which an electromechanical transducer (pi~zo vibrator) is attached in order -to emit ink droplets at a given fre~uency. The printer head 30 fur-ther includes a charging tunnel for charging the ink droplets in accordance with a print information signal. The charged ink droplets are deflected while they pass between a pair ~22~
of deflection electrodes which are also included in the printer head 30. The ink droplets not contributing to the actual printing operation are no~ charged nor deflected, and are directed to a beam gutter 34. The ink li~uid collected by the beam gutter 34 is returned to the ink cartridge 10 via a return conduit 36. The ink liquid in-troduced into -the return conduit 36 is fed to the ink dis-charge needle 18 by means of a suction pump 38. Valves 40 and 42 are associated with -the suction pump 38 to ensure the return of the ink liquid operation.
The ink cartridge 10 is provided with a cylindri-cally-shaped projecting opening 44 formed in the upper sur-face thereof. The outer periphery of the projecting opening 44 is provided with a threaded portion to which a cap 46 15 i8 engaged. q'he cap 46 is removed from the projecting open-in~ ~ wh~n new ink li~uid is lntroduced into the ink cart-ridge 10. The cap 46 includes handling ribs 48, and flat plate portions 50 which ensure tight connection between the cap 46 and the upper surface of the ink cartridge 10. When the ink jet system printer is placed in an operating condi-tion, the cap 46 is slightly loosened so as to ensure that the ink liquid 14 is contained in the ink cartridge 10 at atmospheric pressure.
Communication~seal portions 52 and 54 are formed on the bottom wall of the ink cartridge 10 throu~h which the in]c intake needle 12 and the ink discharge needle 54 are inserted, respectively. The communication/seal portions 52 and 54 each have the same construction.
The communication/seal portion 52 or 54 includes a cylindrically-shaped projection 56 which has an ink liquid passage 58 ~ormed through the center of the cylindrically-shaped projection 56. A threaded portion 60 is formed on the outer periphery of cylindrically-shaped projection 56.
A seal cap 62 has a threaded portion formed on an inner cy-lindrical surface thereof, the threaded portion being engag-ed with the threaded portion 60 of the cylindrically shaped projection 56. The seal cap 62 is provided with a communi-cation opening ~4 which is formed at the center of the bottom wall of the seal cap 62. A seal rubber 66 for sealing the ink liquid passage 58 formed in the cylindrically-shaped projection 5~, and an ink liquid absorbing pad 68 made of sponge are disposed between the cylindrically~shaped projec-tion 5~ and the seal cap 62.
When the thus-constructed ink cartridge 10 is se-cured to the ink liquid supply system, the ink intake needle 12 is inserted through the ink liquid absorbing pad 6B and the seal rubber 66 via the communication opening 64. The tip end of the ink intake needle 12 reaches the ink liquid 14 disposed in the ink cartridge 10 so as to intake the ink liquid 14 from the ink cartridge 10 into the ink liquid sup-ply system. In a same manner, the ink discharge needle 18 is inserted through the ink liquid absorbing pad 68 and the seal rubber 66 so that the ink liquid developed from the suction pump 38 is introduced into the ink cartridge 10.
When desired, the ink cartridge 10 is removed from the ink liquid supply system. At this moment, the seal rub-bers 66 and the ink liquid absorb ng pads 68 are removed Erom the ink intake needle 12 and the ink discharge needle 18. If any of the ink liquid 14 remains in the ink cartridge 10, the ink liquid may flow through the holes formed by the ink intake needle 12 and the ink discharge needle 18 in the seal rubbers 66. However, the thus-leaked ink liquid is absorbed by the ink liquid absorbing pads 68, thereby pre-ven-ting the ink liquid from dripping onto the ink jet system printer. Furthermore, the ink liquid absorbing pads 68 func-tion to wipe off ink liquid attached to the ink intake needle 12 and the ink discharge needle 18 when the ink cartridge 10 is removed from the ink liquid supply system.
An embodiment of the invention being thus describ-ed, it will be obvious that the invention may be varied in many ways. Such variations are not to be regarded as a de-parture from the spirit and scope of the inven-tion, and all 35 such modifica-tions are intended to be included within the scope of the following claims.
