In this case, if the container IDA of the injection tool ID is made transparent and a scale IDB is attached, the ink injection amount can be visually confirmed and is convenient as a guide.

After that, the ink occlusion body 15A is inserted into the first storage chamber 11, and the ink occlusion body 1 is inserted by the injector ID.
Ink is poured into 5A (see FIG. 3C).

Finally, the lid 30 is swung in the direction of the arrow f ₁ , the inward locking portion 32 is engaged with the outward rib 14, and the state shown in FIG. Is completed.

(Second Embodiment) As shown in FIGS. 4 and 5, there are many points in common with the first embodiment. Therefore, the different points will be mainly described below.

[0064] That is, opened holes 16A in the side wall 16 of compartment 11A of an ink tank IT _2, configuration in which affixed a hermetic seal 17 is a characteristic point, in the refill process, again an ink occlusion body 15A The process of accommodating it in the compartment 11A is common.

Therefore, in the next step, the opening of the compartment 11A is closed by the lid 30.

Next, in filling the ink occlusion body 15A with ink, the sealing sheet 17 is peeled off, the ink tank IT ₂ is rotated 90 degrees, and the seal 17 is arranged on the upper side as shown in FIG. The through hole 16A is opened, and the injection needle for the injection tool ID is inserted into the compartment 11 through the through hole 16A.
The ink is replenished by being inserted into A. In this case, first, the tip of the injection needle is made to face the vicinity of the communication hole 10 ', the ink is injected into the second storage chamber 12, and then the injection needle is pulled back to some extent. By filling the occlusion body 15A with ink, the ink can be effectively replenished to the first and second storage chambers 11 and 12, and then the through hole 16A is closed again by the sealing seal 17. . If a rubber sheet having a large elastic restoring force is adopted instead of the hermetic seal 17, ink can be replenished by allowing the injection needle to penetrate, so that peeling and resealing work are unnecessary.

Also, in this embodiment, the ink occlusion body 1
When it is not necessary to replace 5A, for example, for Example 6 or Example 7, the lids 1300 and 2400 are kept closed as shown in FIG. 12 or FIG.

Therefore, when the ink is refilled, the inward locking portion 132 is disengaged from the outward rib 140 and the lid 130 is removed from the top of the container 100 to remove the first and second storage chambers. The used ink occlusion bodies 200, 300 are extracted from the inside of 120, 120A, and the fresh ink occlusion bodies 200, 300 are again extracted into the storage chambers 120, 12 respectively.
It is to be loaded into the 0A, but it goes without saying that if the used ink occlusion body 200 or 300 is not relatively damaged and can be reused as it is, it is not necessary to replace it. That's a good thing.

Further, even if the used ink tank IT ₃ is in the container ₁ in which the second storage chamber 12 lacks the ink occlusion body like the ink tank IT _{1 in} the first embodiment, the refilling is performed. It goes without saying that it is sufficient to fill the second storage chamber 120A with the ink occlusion body 300 during the processing.

Next, the operation procedure of the refill process will be described with reference to FIG.

That is, the ink tank I in which the ink is exhausted
At T ₃ , the lid 130 is pulled up in the direction of the arrow a ₃ ,

Next, the fresh ink occlusion bodies 200 and 300 are urged in the directions of the arrows c ₃ and d ₃ to be accommodated in the first and second accommodating chambers 120 and 120A (FIG. 7B).

Next, each ink occlusion body 2 is determined by the injection tool ID.
Inject enough ink into 00,300,
_The refill process is completed by lowering the lid 130 in _three directions to bring it into contact with the open top of the container 100 and to lock the inward engaging portion 132 with the outward rib 140.

(Embodiment 4) Since this embodiment has many parts in common with the embodiment 3 of the previous section, the main points will be described as follows.

[0079] That is, as shown in FIGS. 8 and 9, the partition wall 110 provided in the container 100 of the ink tank IT ₄ '
Is attached to the container 100 in a detachable manner as indicated by a phantom line.

[0080] Accordingly, the hitting refill process, remove the used ink absorbing body 400, after removing by extraction the partition wall 110 'in the arrow g ₄ direction, integrally in the container 100 so as to fill the form The ink occlusion body 500 of FIG.

In this case, the ink occlusion body 500 can be handled in a clean state by using the replenishment pack PS of Example 5 shown in FIGS. 10 and 11 described later.

(Fifth Embodiment) That is, as shown in FIGS. 10 and 11, the ink occlusion body 500, which is previously compressed and impregnated with ink, is laminated with a thin plastic sheet or a metal foil to vent the air. Hollow rectangular parallelepiped accommodating body 510 formed of a non-conductive material
A replenishment pack PS is accommodated inside the container 510, and a through hole 512 is opened in the top wall 511 of the container 510, and the through hole 512 is opened by a peeling seal 513, and the bottom wall is opened. A through hole 515 is also opened in 514,
The through hole 515 can be opened by a peeling seal 516.

Therefore, in use, the storage pack 510 is loaded into the container 100 from which the partition wall 110 'shown in Embodiment 4 is removed, with the peeling seals 513 and 516 removed, and used.

In the case where the ink storage member 500 is processed in a compressed state in advance, the compression direction may be not only the overall compression but also the vertical or horizontal compression. .

It is also possible to provide an opening in the bottom wall 514 and to provide a filter (for example, reference numeral 21 in FIG. 1) made of a flexible material such as plastic in the opening.

Further, as the container 510 for accommodating the ink occlusion body 500, one that occludes ink of a different color such as magenta or cyan as well as yellow is adopted,
Compartments 11A and 11B in FIG. 2 described above
Alternatively, it goes without saying that they can be selectively attached to and detached from each of the 11C.

(Embodiment 6) In the ink tank IT ₅ of Embodiment 6 shown in FIG.
00 is fixed, and ink is replenished from the vent hole 1330. As the replenishing tool ST, a replenishing tank ST ₂ having a supply needle ST ₁ hung vertically as shown in FIG.

Between the 330 and the supply needle ST ₁ , it is desirable to provide a slight gap for letting the air in the room escape to the outside or another ventilation hole in another part of the lid 1300.

In this case, if the deaeration ink is adopted, the ink can be replenished into the container 1000 more effectively while eating the small air bubbles inside the ink occlusion body 1500 in a state where the ink naturally drops. It is possible to supply ink that enhances the reliability of the head. Further, it can be said that it is desirable that the ink supply amount is about half or less of the volume of the first storage chamber 1400.

(Embodiment 7) In the ink tank IT ₆ of Embodiment 7 shown in FIG. 13, the ink occlusion body 2100 adjacent to the first accommodating chamber 2200 accommodating the ink occlusion body 2100 of the container 2000 is mounted. A replenishment hole 2410 is provided in a lid 2400 fixed to the container 2000 to replenish ink directly to the second storage chamber 2300 which is not formed, and the replenishment hole 2410 is openably closed by a peeling seal 2420. Therefore, in use, the peeling seal 2420 is made using, for example, an injection tool ID (see FIG. 14) described later.
The ink is replenished by inserting the injection needle IN into the replenishment hole 2410 that has been peeled off and opened. Also in this case, as in the sixth embodiment, there is a slight gap between the supply hole 2410 and the injection needle IN or the second storage chamber 2300 of the lid 2400.
It is desirable to provide ventilation holes on the side.

Instead of the peeling seal 2420, a rubber sheet having a large elastic restoring force may be attached, and the injection needle IN may be threaded through the rubber sheet to enable ink supply.

(Embodiment 8) FIGS. 14 and 15 show a syringe-shaped ink injector ID, which is characterized by a scale IDB on the container IDA and an injection needle I.
This is because the scales M _{1 to} M ₇ are marked in the longitudinal direction of N. When using, the ink replenishment amount can be adjusted while observing the scale IDB, and the scale needles M _{1 to} M ₇ can be used. Since the depth of invasion of IN into the ink occlusion body can be detected and the ink can be poured into the ink occlusion body at a desired depth position, the ink can be effectively absorbed throughout the ink occlusion body. is there. In addition, it is preferable that the ink injection tool ID is packaged with a non-breathable material such as aluminum or an aluminum laminate material, and the ink that has been degassed in advance is filled for supply.
If necessary, degassing ink may be stored in a storage pack (not shown) formed of a material having no gas permeability, and a refill kit may be formed by combining the degassing ink with an empty injection tool ID.

(Embodiment 9) This embodiment 9 shown in FIGS. 16 and 17 is an ink replenishment set SS, in which various different color inks are loaded into the ink injector ID shown in the embodiment 7. And arrange them on the base plate SS ₁ ,
The ink occlusion body PA is also placed on the base plate SS ₁ , and these are covered with the cover sheet SS ₆ having the recesses SS _{2 to} SS ₅ that are in conformity with the injection tool ID and the external shape of the ink occlusion body PA. The ink replenishment set SS can be used by detaching the cover sheet SS ₆ from the base plate SS ₁ and taking out the injector ID or the ink occlusion body PA for use. .

[0093]

The present invention is as described above, and the remarkable effects brought about by the constitution are as follows.

(1) Reusable ink tank. Not only can it be used for a long period of time because the ink occlusion body or ink can be easily replenished in the storage chamber partitioned by the partition wall inside the ink tank container, but it also does not dispose of the used ink tank, which causes environmental pollution. It is highly effective because it can be prevented.

(2) Ink supply process in a clean state. The ink occlusion body can be refilled with ink in a clean state without being contaminated by opening and closing the lid of the container of the ink tank, and the container of the ink can be filled by using an ink injecting tool or a replenishing tool. Since the ink can be replenished without opening and closing the lid, there is no risk of the operator being soiled.
