Definitions

  • the present invention relates to: an ink cartridge for containing ink for ink jet recording, wherein the ink cartridge is capable of preventing the ink from being damaged in its degassed properties; a manufacturing method for manufacturing the ink cartridge, wherein the manufacturing method is simplified; and, an ink jet recording apparatus using the ink cartridge.
  • each of a plurality of ink compartments arranged in an ink head of the ink jet recording apparatus is subjected to a positive pressure in response to an electric signal received.
  • a droplet of ink contained in each of the ink compartments is ejected from a nozzle onto a recording medium to form an information image thereon, wherein the nozzle communicates with each of the ink compartments.
  • a method for applying the positive pressure to the ink compartment there are: a method using a piezoelectric element, actuation of which causes the ink compartment itself to vary in volume; a method using a heating element to heat the ink of the ink compartment to produce a vapor bubble therein; and, a like.
  • air entering an ink passage such as the ink compartments of a printing head and a like decreases an ink ejection pressure to an insufficient level, which causes ink ejection failures and ink dot omissions to impair reliability of the ink jet recording apparatus.
  • the ink jet recording apparatus when a used ink cartridge is replaced with a new one, a relatively large amount of air enters inside ink passages of the printing head. Due to this, a relatively extended period of time is often required before the ink jet recording apparatus stabilizes in printing quality at an expense of a relatively large amount of ink.
  • a conventional method uses a degassed ink. Using such a degassed ink, it is possible to reabsorb any existing air bubble remaining in the printing head, which improves the ink jet recording apparatus in reliability.
  • the ink cartridge is provided with: an ink supply port for supplying ink to the ink cartridge; and, an atmosphere communication port which prevents any negative pressure from being produced inside the ink cartridge when the ink is consumed in an ink jet recording operation. Further, in order to prevent the ink from being damaged in its degassed properties, the ink cartridge has its interior subjected to a pressure reducing treatment.
  • JP-A- 7-132611 there has been proposed a conventional method for packaging the ink cartridge in a hermetic container which is capable of holding the ink cartridge under negative pressure by using a sealing film, which is not permeable to water vapor but is permeable to gases, to seal both the ink supply port and the atmosphere communication port.
  • the conventional method is complicated, because it includes: an ink supplying step which should be performed under negative pressure; a sealing step which should be performed at 1 atmospheric pressure; and, a re-degassing step which should be performed under negative pressure.
  • the conventional method needs such the re-degassing step.
  • the sealing step is performed at 1 atmospheric pressure in spite of a fact that the ink supplying step is performed under negative pressure.
  • a purpose of the sealing film which is not permeable to water vapor but is permeable to gases, is to enable a method to perform the re-degassing step.
  • the conventional method is not capable of preventing the ink from being damaged in its degassed properties. This is because the degassed properties of the ink are damaged when the ink is brought into contact with atmosphere in the sealing step of the conventional method. In general, it is difficult to sufficiently degas the ink by using negative pressure only. Incidentally, it is possible to degas the ink to a predetermined degassed level by using a hollow fiber membrane and a like. Further, it is possible to prevent the ink from being damaged in degassed properties by packaging the ink cartridge under negative pressure. In this case, however, once the degassed properties of the ink are damaged, it is difficult for the degassed properties of the ink to recover from such damage.
  • an object of the present invention to provide an ink cartridge for containing ink for ink jet recording, wherein the ink cartridge is capable of preventing the ink from being damaged in its degassed properties; a manufacturing method for manufacturing the ink cartridge, wherein a method is simplified; and, an ink jet recording apparatus using the ink cartridge.
  • an ink cartridge including:
  • a preferable mode is one wherein a port is shared between the pressure reducing port and the ink supply port.
  • a preferable mode is one wherein the sealing member is made up of a peelable material.
  • an ink cartridge including:
  • a preferable mode is one wherein the first step and the second step include a ninth step of sealing the atmosphere communication port shut using a sealing member , the sealing member being made of material which is impermeable to both gases and water vapor.
  • a preferable mode is one wherein the seventh step includes a tenth step of producing a vacuum of equal to or less than 160 torr in the pressure reducing chamber.
  • a preferable mode is one wherein the second step and the third step include an eleventh step in which the pressure reducing port is formed in a same port with the ink supply port to serve also as the ink supply port; and, the fifth step and the seventh step include a twelfth step in which the degassed ink is supplied after the ink chamber of the main body of the ink cartridge is reduced in pressure through the ink supply needle.
  • an ink jet recording apparatus provided with an ink cartridge, the ink cartridge being produced by a method including:
  • Fig. 1 shows a longitudinal sectional view of an ink cartridge of a first embodiment of the present invention.
  • Fig. 2 shows an exploded perspective view of the ink cartridge shown in Fig. 1.
  • Fig. 3 shows a longitudinal sectional view of the ink cartridge shown in Fig. 1, illustrating its manufacturing method.
  • a foam member 8 is constructed of a porous material such as a polyurethane foam or a like, and mounted in an ink chamber 2.
  • the ink chamber 2 is provided inside an ink cartridge main body 1 of the ink cartridge in an insertion manner. Further, the ink chamber 2 is closed with a pair of lids 12a, 12b. These lids 12a, 12b are provided with a pressure reducing port 3, an ink supply port 4 and an atmosphere communication port 5.
  • a resilient element 6 is made up of butyl rubber or a like, and press-fitted into each of the ink supply port 4 and the pressure reducing port 3.
  • the resilient element 6 is fixed by means of the lids 12a, 12b.
  • Physical properties required of the resilient element 6 are ink-resistant properties and sufficient resiliency. Namely, the resilient element 6 requires sufficient resiliency, to say nothing of a necessity of the ink-resistant properties. Necessity of sufficient resiliency will be described later in detail. Incidentally, it is possible to omit use of the pressure reducing port 3. A method of manufacturing the ink cartridge in which the pressure reducing port 3 is omitted will be described later.
  • the atmosphere communication port 5 is sealed with a peelable sealing member 7a.
  • This sealing member 7a may be constructed of a material, for example such as an aluminum sheet or a like, which is impermeable to gases and water vapor.
  • the ink cartridge main body 1 is provided with a printing head 15.
  • the printing head 15 is provided with an ink supply portion 11 in its connection side.
  • a filter 9a for filtering the ink.
  • the ink cartridge main body 1 In mounting the ink cartridge main body 1 on the printing head 15, the ink cartridge main body 1 is fitted to a joint 13 in an insertion manner.
  • the joint 13 is provided with a filer 9b.
  • This filter 9b is provided in a printing head casing 14.
  • a packing member 10 made up of a resilient material such as rubber or a like is interposed between the ink cartridge main body 1 and the joint 13.
  • a sealing member 7b is provided in a lower portion of the packing member 10. This sealing member 7b may be constructed of a material impermeable to gases and water vapor as is in a case of the sealing member 7a.
  • the ink is supplied from the ink cartridge main body 1 to the printing head 15 under influence of negative pressure.
  • This negative pressure is created by a suction pump 21, and applied to an interior of a cap 20 through tubings 23 in a condition in which the cap 20 is hermetically connected with a nozzle plate (not shown) of the printing head 15.
  • the ink received in the cap 20 is discharged out of the cap 20 through use of suction force applied to interior of the cap 20 through the tubing 23 and an atmosphere communication valve 22.
  • Ink (not shown) is filled in the printing head 15 under influence of the above suction force.
  • a positive pressure is applied to each of a plurality of ink compartments (not shown) which are arranged in the printing head 15, so that an ink droplet is ejected from a nozzle (not shown) which is communicated with each of the ink compartments (not shown), whereby an information image is formed on a recording medium (not shown).
  • the ink chamber 2 including the ink supply portion 11 is subjected to large negative pressure.
  • the ink supplied into the ink chamber 2 is, due to capillarity, further supplied into the nozzle (not shown) of the printing head 15, and stably held therein because the ink forms a meniscus on a surface of a discharge port (not shown) at a leading end portion of the nozzle (not shown).
  • the meniscus of the ink is deeply pulled into the nozzle (not shown) of the printing head 15.
  • a magnitude of the large negative pressure exceeds a certain limit (that is, surface tension of the ink in the meniscus)
  • the meniscus of the ink is broken to make it impossible to eject any ink droplet from the leading end portion of the nozzle (not shown).
  • the cap 20 is hermetically connected with the nozzle plate (not shown) of the printing head 15 to have the interior of the cap 20 subjected to negative pressure, which is created by the suction pump 21 and applied to the interior of the cap 20 through the tubing 23 extending from the pump 21 to the cap 20.
  • negative pressure remains inside the ink chamber 2 after sufficient amount of ink is pulled into the printing head 15.
  • the ink (not shown) received in the printing head 15 is pulled back into the ink chamber 2 under the influence of such negative pressure of the interior of the ink chamber 2, which makes it difficult to supply the ink to the ink printing head 15 in the ink jet recording operation. Consequently, it is necessary to open the atmosphere communication port 5 before the ink jet recording operation is performed using the ink cartridge of the first embodiment of the present invention.
  • the lids 12a and 12b are provided with the pressure reducing port 3, the ink supply port 4 and the atmosphere communication port 5 and so forth, and mounted on the ink cartridge main body 1 which has been already provided with the packing member 10, the filter 9a, the foam member 8 and so forth. After that, under such circumstances, the ink is supplied to the ink cartridge main body 1.
  • the ink cartridge main body 1 is mounted in a pressure reducing chamber 30 in which: as shown in Fig. 3, an ink supply needle 32 and a pressure reducing needle 31 are inserted into the ink supply port 4 and the pressure reducing port 3 of the ink cartridge main body 1, respectively, in a manner such that each of the ink supply needle 32 and the pressure reducing needle 31 penetrates the resilient element 6 which is press-fitted into each of the ink supply port 4 and the pressure reducing port 3.
  • the ink chamber 2 is evacuated to pull air out of the ink chamber 2 through the pressure reducing port 3.
  • ink 35 which is received in an ink tank 36 and is still not degassed, is degassed through a degassing treatment portion 33 in which a hollow fiber membrane or a like is used to degas the ink 35.
  • the thus degassed ink is then supplied to the ink chamber 2 through the ink supply port 4.
  • the pressure reducing chamber 30 is evacuated to a negative pressure of less than or equal to 160 torr.
  • both the pressure reducing needle 31 and the ink supply needle 32 are retracted.
  • both the pressure reducing port 3 and the ink supply port 4 are automatically closed with the resilient element 6 due to its resiliency.
  • the degassed properties of the ink used in the first embodiment will be described with reference to measurement results of the degassed properties, wherein the degassed properties of the ink represents an amount of air dissolved in the ink.
  • the following Table 1 shows the measurement results of a level of the ink dissolved oxygen (hereinafter referred to as DO values).
  • each of the pressure reducing port 3 and the ink supply port 4 of the comparative example of the ink cartridge was not provided with the resilient element 6, and was sealed with a sealing member which is permeable to gases but not to water vapor; and, the comparative example of the ink cartridge thus prepared was then packaged under negative pressure to degas its ink, the DO values of which were measured and listed in the following Table 1.
  • DO values [mg/L] in Embodiment DO values [mg/L] in Comparative Example Measurement conducted immediately after ink supply operation From 0.9 to 1.3 From 2.3 to 2.9 Measurement conducted after two-day lapse from ink supply operation From 1.0 to 1.3 From 2.2 to 3.0 Measurement conducted after 30-day lapse from ink supply operation From 1.0 to 1.2 From 2.3 to 3.1
  • the DO value of the ink still not degassed was within a range of from 7.5 to 8.5 mg/L at the ambient temperature of 25 °C under the ambient pressure of 1 atmospheric pressure.
  • the Table 1 shows that: the degassed state of the ink was kept for a considerable period of time in both the embodiment and the comparative example; and, an initial level of degassed properties of the ink in the embodiment was more than twice as large as that of degassed properties of the ink in the comparative example.
  • This difference in initial level of the degassed properties between the embodiment and the comparative example is resulted from a difference in ambient conditions of the ink after completion of the ink supply operation between the embodiment and the comparative example, wherein the ink in the embodiment after completion of the ink supply operation was prevented from communicating with the atmosphere, while the ink in the comparative example after completion of the ink supply operation was permitted to communicate with the atmosphere. Consequently, judging from measurement results of the above Table 1, it is recognized that the degassed properties of the ink are damaged when the degassed ink is brought into contact with the atmosphere, because air in the atmosphere tends to dissolve in the degassed ink.
  • the comparative example of the ink cartridge is packaged under negative pressure to keep the degassed properties of the ink
  • packaging performed under negative pressure has substantially no effect on improvements in the degassed properties of the ink.
  • a degassing operation of the ink is performed by using a hollow fiber membrane. Once the degassed properties of the ink are damaged, it is difficult to improve thus damage degassed properties of the ink by using the negative pressure only.
  • the dot omission rate is very rate in the images formed using the embodiment, which rate is substantially equal to one hundredth of the dot omission rate of the image formed using the comparative example.
  • a reason why the dot omission rate in the image formed using the embodiment is very rare is that: a more the degree of degassing level of the ink increases, a more likely the air dissolves in the thus degassed ink and thereby reabsorbing any air bubbles existing in the printing head 15.
  • the measurement results or values listed in the Table 2 reflects a difference in the degassed properties of the ink between the embodiment and the comparative example both listed in the Table 1.
  • the ink chamber 2 is filled with the foam member 8; the lids 12a, 12b are provided with the ink supply port 4, the pressure reducing port 3 and the atmosphere communication port 5; the sealing member 7a for hermetically sealing the atmosphere communication port 5 is provided; the resilient element 6 is inserted into each of the ink supply port 4 and the pressure reducing port 3; and, the sealing member 7a is made of material impermeable to both gases and water vapor.
  • the ink supply needle 32 and the pressure reducing needle 31 are inserted into the ink supply port 4 and the pressure reducing port 3, respectively, so that the ink chamber 2 is evacuated to pull the air out of the ink chamber 2 through the pressure reducing port 3. Under such circumstances, the degassed ink is supplied to the ink chamber 2 through the ink supply port 4.
  • both the pressure reducing needle 31 and the ink supply needle 32 are retracted to permit each of the pressure reducing port 3 and the ink supply port 4 to be automatically closed with the resilient element 6 under the influence of its resiliency.
  • the ink supply needle 32 is completely sealed, it is possible to prevent any ink leakage from occurring in the ink supply operation, which permits a large amount of the ink to be supplied to the ink chamber 2.
  • the resilient element 6 is inserted in each of the ink supply port 4 and the pressure reducing port 3, and since the sealing member 7a is made of material impermeable to both gases and water vapor, it is possible to prevent any ink leakage from occurring in the ink cartridge of the embodiment even when the ink cartridge of the embodiment is subjected to a mechanical impact and variations in ambient temperature.
  • the degassed ink since the degassed ink is prevented from communicating with the atmosphere after completion of the ink supply operation, there is no danger that degassed properties of the ink are damaged during manufacturing steps of the ink cartridge. Further, since the sealing member 7a is made of material impermeable to both gases and water vapor, there is no danger that the degassed properties of the ink are damaged even when the ink is stored for an extended period of time.
  • the ink cartridge of the embodiment prevent any air from entering the ink cartridge when the ink cartridge of the embodiment is mounted in the printing head 15, which may prevent any ink ejection failures from occurring in ink jet recording operation.
  • the ink jet recording apparatus By using the ink cartridge of the embodiment produced in the above-mentioned manufacturing method, it is possible to realize a small-sized ink jet recording apparatus at low cost, wherein the ink jet recording apparatus is stabilized in ink ejection pressure created in the printing head 15, and may be free from any dot omission and ink ejection failure. Due to this, the ink jet recording apparatus using the ink cartridge of the embodiment is improved in reliability.
  • Fig. 4 shows a longitudinal sectional view of an ink cartridge of a second embodiment of the present invention, illustrating its manufacturing method.
  • a pressure reducing port 3 shown in Figs. 1 to 3 is eliminated. Consequently, an ink chamber 2 is evacuated through an ink supply port 4 not through the pressure reducing port 3.
  • an ink cartridge main body 1 provided in an ink cartridge main body 1 are: a packing member 10; a filter 9a; a foam member 8; and, other components.
