Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 and 3, the ink cartridge fastener 20 of the present invention includes a case 22 for mounting the ink cartridge 10 when extracting the ink and air in the ink cartridge 10, and the case ( 22, the first pad 24 is installed in close contact with the periphery of the ink spray nozzle 10b formed on the print head of the ink cartridge 10.

The case 22 is made of an elastic material such as plastic, and is formed in a shape of wrapping from the print head portion of the ink cartridge 10 to the lower end portion of the other end, and the first pad 24 is formed on one side. The coupling hole 22a is formed by inserting from the lower part to be coupled to the lower part, and the fixing protrusion 22b is slightly elastic to receive and hold the locking protrusion 10d of the ink cartridge 10 at the other end thereof. It is formed in the state which has.

The fixing protrusion 22b is formed with a locking jaw having a shape inclined so that the locking protrusion 10d of the ink cartridge 10 is easily caught and detached toward the inside of the case 22, and the ink cartridge 10 is formed on the upper surface thereof. When mounting or detaching the case 22, a finger seating recess is formed so that it is easy to flip the fixing protrusion 22b with a finger. In addition, both sides of the fixing protrusion 22b of the lower surface of the case 22 may be provided with a cutout groove in the longitudinal direction thereof so that the fixing protrusion 22b may be elastic and folded depending on the material of the case 22.

In addition, a pair of guides 22c are formed at an inner surface bottom of the case 22 so as to be seated when the ink cartridge 10 is coupled to the case 22.

The first pad 24 has a coupling portion 24b extending in one horizontal direction from the vertical flat plate 24a to be fitted into the coupling hole 22a of the case 22 from the bottom thereof. An edge-shaped adhesion protrusion 24c is formed at 24a for adhering the ink injection nozzle 10b of the ink cartridge 10, and the coupling portion 24b is formed at the center of the adhesion protrusion 24c of the vertical flat plate 24a. The tapered through hole 24d penetrating the through hole is formed.

The inner part of the contact protrusion 24c should be slightly recessed so as not to come into close contact with the ink injection nozzle 10b when the ink cartridge 10 is mounted.

The process of mounting the refilled ink cartridge to the ink cartridge fixture of the present invention configured as described above will be described with reference.

First, the first pad 24 is inserted into the coupling hole 22a of the case 22 from the bottom thereof to engage the case 22, and the ink spray nozzle 10b of the ink cartridge 10 is connected to the first pad 24. Push the inner side of the case 22 so as to contact the vertical plate 24a of the ink cartridge 10 while rotating the other side of the ink cartridge 10 is inserted into the case 22.

When the ink cartridge 10 is pressed while being rotated in this manner, the locking protrusion 10d of the ink cartridge 10 pushes down the fixing protrusion 22b of the case 22 and bends down by the elasticity of the portion of the fixing protrusion 22b. The locking protrusion 10d that is pushed into this way is caught by the locking jaw due to the force to be returned to its original position by the elasticity of the fixing protrusion 22b. At this time, the lower surface of the ink cartridge 10 is fixed in a state seated on the guide 22c of the bottom of the inner surface of the case 22.

When the ink cartridge 10 is fixed to the case 22 as described above, the ink jetting nozzle 10b of the ink cartridge 10 and the contact protrusion 24c of the pad 24 come into close contact with each other. At this time, the ink spray nozzle 10b of the ink cartridge 10 is formed between the pads 24 because the inner part of the contact protrusion 24c of the vertical flat plate 24a is concavely recessed, so that a fine space is formed. Nozzle 10b is not damaged.

In this state, the ink cartridge 10 is mounted in the ink cartridge fixing tool 20, and then the injection portion of the pressure regulator (not shown) is inserted into the through hole 24d of the first pad 24, so that the inside of the ink cartridge 10 is inserted. By removing a predetermined amount of ink or air filled in the air, the internal pressure of the ink cartridge is regulated, and the flow path of the ink injection nozzle 10b is secured and cleaned.

In this way, after adjusting the internal pressure of the ink cartridge 10, to remove the ink cartridge 10 from the case 22 assembled with the ink cartridge fixture 20, the case 22 is held by one hand and the other hand. By gently pressing and rotating the ink cartridge 10 toward the first pad 24 assembled to the case 22 while holding the ink cartridge 10, the ink cartridge 10 is easily taken out.

When the ink cartridge 10 is attached to or removed from the case 22 as described above, it can be easily installed or detached easily and effortlessly by pressing down the mounting recess of the fixing protrusion 22b.

4A to 4C are separated perspective views showing a state in which the ink cartridge fastener according to the present invention is applied to an ink refilling kit, and has a separate cap 26c at the injection portion 26b of the tip of the container body 26a for storing ink. ), A pressure regulator 28 for inserting the ink container 26 into the through-hole 24d of the first pad 24 and extracting ink and air in the ink cartridge 10 is provided. It is added to the ink cartridge fixture 20.

The ink container 26 has a sharp injection portion 26b formed at the tip of the hollow container body 26a, and is covered with a cap 17c to surround the injection portion 26b so as not to leak ink therein.

The pressure regulator 28 is a syringe consisting of a cylindrical cylinder 28a having a pointed injection portion 28c formed at a tip of a tube shape and a piston 28b sliding in an airtight state inside the cylindrical cylinder 28a. It is formed in the form. The pressure regulator 28 adjusts the internal pressure of the ink cartridge 10 after recharging the ink to the ink cartridge 10 to balance the pressure of the cylindrical cylinder 28a with the through-hole 24d of the pad 24. By inserting the injection portion 28c and pulling the piston 28b, the ink and air inside the ink cartridge 10 are drawn out.

Although the pressure regulator 28 is illustrated and described above in the form of a syringe, this is only one embodiment, and may be any type as long as it can extract ink and air from the ink cartridge 10.

For example, a bellows type or a spherical tube type pressure regulator having an injection part fitted into the through hole 24d of the pad 24 to be kept airtight may be used.

As shown in FIG. 4B, when the ink cartridge 10 is separated from the printer and stored for a long time, the first pad 24 is closed at the end of the coupling portion 24b so as not to dry the ink injection nozzle 10a. The blocking cover 29 to be covered on the part may be separately provided. The blocking cover 29 may be provided as a blocking cover of a shape having an insertion protrusion formed at the center of the disc and being handled on the other side so as to be pushed into the through hole 24d of the coupling portion 24b.

In addition, the first pad 24 may be replaced by a second pad 240 that closes the through hole 24d of the first pad 24 as shown in FIG. 4C.

The injection hole 10c of the ink cartridge 10 may be any type so long as it blocks the injection hole 10c so that the internal pressure of the ink cartridge 10 is maintained by a fine air flow path. It can be sealed with tape and a fine air flow path can be formed in the center thereof.

The process of recharging ink in the ink cartridge 10 using the ink refill kit of the present invention as described above will be described in detail.

First, the process of mounting the ink cartridge 10 to the case 22 constituting the ink cartridge fixing fixture of the ink cartridge 10 of which the ink is exhausted is the same as described above, so a detailed description thereof will be omitted. When the ink cartridge 10 is mounted on the case 22 as described above, the periphery of the ink injection nozzle 10b and the adhesion protrusion 24c of the pad 24 are brought into close contact with each other, and the ink injection nozzle 10b is attached to the pad 24. Since the inner part of the contact protrusion 24c of the recess is concavely recessed, a fine space is formed without touching.

Then, the injection hole 10c of the ink cartridge 10 is placed at the upper end portion, and the adhesive tape attached to the surface of the injection hole 10c is removed and removed.

Then, the process of pressing the container body portion of the ink container 26 in a state of inserting the injection portion 26b of the ink container 26 in which ink is stored in the injection hole 10c is repeated several times. Is injected into the ink cartridge 10, the injection portion 26b of the ink container 26 is removed from the injection hole 10c of the ink cartridge 10, and then the injection hole 10c is blocked with an adhesive tape or stopper. Fine air flow paths should be formed.

In this way, the ink cartridge 10 is filled with ink and the pressure regulator is adjusted to the through-hole 24d of the pad 24 in the state in which the ink spray nozzle 10b inside the ink cartridge 10 is placed at the bottom as in the case of filling the ink. After inserting the injection section 26b of (26), the piston 26c in the cylindrical cylinder 26a constituting the pressure regulator 26 is grabbed and retracted, so that between the through hole 24d of the pad 24 and the cylindrical cylinder 26a. In the vacuum state, and the ink and air in the ink cartridge 10 is sucked.

The reason for extracting the ink and air inside the ink cartridge 10 by using the pressure regulator 26 is to remove the air portion blocking the lump or flow condensation on the ink spray nozzle 10 in this process. (10) This is because the flow path is secured until the ink impregnated in the inner sponge reaches the ink spray nozzle 10b, and the ink spray nozzle 10b must be washed. At this time, the suction amount of the ink and air taken out from the ink cartridge 10 is about 2-7 kPa. The reason for this is that when the ink amount of 2 kPa or less is taken out, the ink spray nozzle 10 is not completely cleaned, and when 7 kPa or more is taken out, there is a large amount of ink loss.

When the internal pressure of the ink cartridge 10 is adjusted as described above, when the cleaning of the ink injection nozzle 10b is completed, the internal pressure regulator 26 is pulled out from the through-hole 24d of the pad 24 to remove the case 22. Only the ink cartridge 10 separated from the installation in the printer is to be used.

If the ink cartridge 10 is installed and used in the printer as described above, the ink in the sponge is consumed and reduced, and as a small amount of air is supplied through the injection hole 10c of the ink cartridge 10 as much ink is consumed as described above, The negative pressure is not applied to the evaporation of the ink as well. Therefore, since the internal air pressure is kept constant regardless of the amount of ink consumed in the interior of the ink cartridge 10, the ink amount is constantly sprayed through the ink injection nozzle 10b.

In this case, when the printer is not used for a long time, the ink cartridge 10 is separated from the printer and stored in the case 22 forming the ink cartridge fixing tool 20.

At this time, the method for storing the ink cartridge 10 may be used by covering the blocking cover 29 for sealing the through hole 24d in the engaging portion 24b of the first pad 24, as shown in Figure 4a, Figure 4b As described above, the second pad 240 without the through hole 24d may be coupled to the coupling hole 22a of the case 22.

When the ink cartridge 10 is mounted on the case 22 forming the ink cartridge fixing tool 20, the contact protrusion 24c of the second pad 240 is formed around the ink jetting nozzle 10b of the ink cartridge 10. Since the ink jetting nozzle 10b is not in contact with the external air due to the close contact, the ink jetting nozzle 10b is prevented from being dried, thereby preventing the ink jetting nozzle 10b from being clogged.

5A to 5B show another embodiment of the case in the ink cartridge fixture which is the main part of the present invention, the case 220 is formed to be wide and to allow the mounting of the wide and narrow ink cartridge of the ink cartridge 10 The two ink cartridges 10 and 100, in which the locking projection 10d is located at the center or biased to one side, can be selectively mounted.

The lower inner surface of the case 220 is formed with a high guide 22d for guiding the narrow ink cartridge 100 to be seated therein, and supports the low-width ink cartridge 10 at the inner position of the guide 22d. Lower pedestal 22c is formed.

When the narrow ink cartridge 100 is mounted on the case 220 in the ink cartridge fixing device as described above, the ink cartridge 100 is seated on the inner pedestal 22c as shown in FIG. 22d) guides the narrow side of the ink cartridge 100 so that the flow of the ink cartridge 100 is restricted.

Then, the wide ink cartridge 10 is seated on the outer guide 22d as shown in Fig. 5b so that it is not disturbed by the lower pedestal 22c therein. Therefore, the ink cartridges 10 and 100 having different widths and the locking protrusions 10d can be selectively mounted on one case 220.

The reason is that although the fixing protrusion 220b is formed to be biased to one side, a part of the locking protrusion 100d of the ink cartridge 100 is caught by the fixing protrusion 220b.

Therefore, when the fixing protrusion 220b is formed to be biased to one side from the center of the case 220, the locking protrusion 10d is formed at the center of the ink cartridges 10 and 100 as well as the locking protrusion 10d is formed to be biased to one side. It can be fixed.

As described in detail above, the ink cartridge fastener according to the present invention can be easily fixed or detached without difficulty of the ink cartridge, and can selectively mount two ink cartridges having different widths and the fixing protrusions formed in the center or on one side. There is an advantage.

In addition, the ink cartridge fastener of the present invention has an advantage that when the printer is not used for a long time, the ink cartridge nozzle can be prevented from being dried and clogged by storing the ink cartridge in a bonded state.

In addition, the ink refill kit of the present invention allows the ink cartridges that are used up to be easily refilled with ink so that the ink cartridges that are used only once and discarded can be repeatedly used, thereby reducing the economic burden on the printer user and disposing of the ink. It has the advantage of reducing resource waste and environmental pollution caused by cartridges.
