It can also be used as a blocking cover inserted into the through hole (14b) formed in the) to block external air.

Looking at the ink refilling method for recharging the ink into the ink cartridge 10 by the ink refill kit of this configuration as follows.

The method for refilling the ink may include attaching the pad 14 to the case 12, attaching the lower end of the ink cartridge 10 to the case 12, and removing the sealing of the ink cartridge 10 inlet 10c. And removing the blocking ball 11 of the injection hole 10c, supplying ink into the ink cartridge 10, sealing the injection hole 10 of the ink cartridge 10, and the inside of the ink bag 20. The process of adjusting the internal air pressure by extracting ink and air.

In more detail, when ink is to be refilled in the ink cartridge 10 in which the ink consumption is completed, first, the pad 14 is attached to one side of the case 12 through the open lower end of the case 12. And the ink ejection nozzle 10a side of the ink cartridge 10 is inserted into the case 12 so that the contact portion 14a of the pad 14 faces the contact portion 14a.

Then, the locking protrusion 10b of the rear end of the ink cartridge 10 is caught by the locking jaw 12a of the case 12, and the ink cartridge 10 is fixed to the case 12, and the edge of the ink injection nozzle 10a is fixed. The close contact portion 14a of the pad 14 is in close contact with the ink injection nozzle 10a and the pad 14 by a concavely recessed portion of one side of the pad 14 to have a fine space.

Then, the inlet 10c of the ink cartridge 10 is erected upwards, and then the seal attached to the surface of the inlet 10c is removed, and the cap which is fastened to the ink container 18 into the inlet 10c ( If the pointed needle of 18a is pressed and pushed, the blocking ball 11 which has blocked the leakage of ink from the inside of the injection hole 10c is pushed into the inside of the ink bag 20.

On the other hand, inside the ink bag 20, an elongated elliptical leaf spring 22 is installed in the center, and elongated plate members 24 are provided on both sides of the elliptical leaf spring 22, and the ink bag 20 consumes ink. While the negative pressure is applied to the inside, the leaf spring 22 is pressed into the ink bag 20 and is maintained in a flat state slightly. When the inlet 10c is opened during ink supply, the internal air pressure becomes atmospheric by external atmospheric pressure. The leaf spring 22 and the ink bag 20 are returned to their original state by the restoring force of the leaf spring 22.

Then, after inserting the front end portion of the ink container 18 in which the ink is stored in the injection hole 10c, the outside of the ink container 18 is pressed to supply the ink to the ink bag 20 of the ink cartridge 10. In this way, the supply of ink is started and after a predetermined time, the ink supply is completed, it may have a predetermined volume of air layer on the inner upper end of the ink bag 20 is filled with ink. On the other hand, after the ink supply is completed, the ink container 18 is removed, and the injection hole 10c is sealed with the injection hole plug 26 in the shape of a tack in the injection hole 10c.

Thereafter, in order to adjust the internal pressure in the ink cartridge 10, first, the protrusion 14c of the pad 14 is turned upside down so that the ink is filled inside the nozzle face. In this case, fine bubbles (air) may be formed inside the irregular nozzle surface. Then, the tip of the pressure regulator 16 is inserted into the protrusion 14c of the pad 14 to pull the piston of the pressure regulator 16, and a vacuum is formed between the tip of the ink injection nozzle 10a and the pressure regulator 16. It becomes a state.

In this state, the piston of the pressure regulator 16 is operated once or several times to remove an appropriate amount (about 2-9 cc) of ink and air from the ink bag 20 inside the ink cartridge 10 to adjust the internal pressure. . The ink and air extraction amount is preferably about 2cc.

Meanwhile, when ink and air are extracted from the ink bag 20, the ink spray nozzle 10a is washed by the extracted ink.

When the internal pressure control is completed, remove the internal pressure regulator 16 and press and hold the handle 12b provided at the rear end of the case 12, pull out the ink cartridge 10 to separate the case 12 from the case 12, and then install it in the printer. Will be used.

When the ink cartridge 10 is installed and used in the printer, as the amount of ink in the ink bag is consumed, both sides of the plate spring 22 are in contact with the ink bag 20 and the plate material 24 in close contact with the ink bag 20. Press to finely compress the leaf spring (22). Then, by the repulsive force of the leaf spring 22 is no longer pressed, the shape is maintained as it is. At this time, the elliptical leaf spring 22 installed in the ink bag 20 and the elongated plate 24 on both sides of the ellipse maintain the internal pressure of the ink bag 20 irrespective of the ink consumption amount. Therefore, since the internal air pressure is kept constant regardless of the amount of ink consumed in the inside of the ink bag 20, the ink amount is uniformly sprayed through the ink injection nozzle 10a.

When the ink cartridge 10 is not used for a long time, the ink cartridge 10 is separated from the printer and inserted into the case 12 to be stored. The method of storing the ink cartridge 10 uses a blocking cover 13 to cover the protrusion 14c on the outside of the pad 14 on which the through hole 14b is formed as shown in FIG. 5 to seal the through hole 14b. As shown in FIG. 4, there is a method of mounting the ink cartridge 10 to the case 12 after mounting the auxiliary pad 15 without the through hole 14b on one side of the case 12.

When the ink cartridge 10 is attached to the case 12 as described above, the close contact portion 15a of the auxiliary pad 15 comes into close contact with the edge portion of the ink injection nozzle 10a of the ink cartridge 10, and the contact portion ( 15a) Since the ink jetting nozzle 10a does not come into contact with external air while having a minute space by the concavely recessed portion of the inner surface, the ink jetting nozzle 10a is prevented from drying. At this time, since the locking protrusion 10b of the ink cartridge 10 is caught in the locking projection 12a of the case 12, the ink cartridge 10 is prevented from being separated from the case 12. In this way, the ink injection nozzle 10a of the ink cartridge 10 can be protected.

As described above, the ink refilling method and the ink refilling kit of the ink cartridge according to the present invention facilitate the operation of refilling the ink into the ink bag by refilling the ink according to the ink refilling method using the ink refilling kit and the disposable ink. The cartridge can be repeatedly used several times, and the ink spray nozzle can be stored for a long time to prevent drying.
