Abstract

PURPOSE:To prevent the lowering in the quality of ink by bringing the ink to a hermetically sealed state, by a method wherein a container having a flat bottom part is constituted of a flexible material, and an openable seal mechanism is provided in an ink lead-out pipe, and a stirrer is provided in a main body. CONSTITUTION:A container main body 1 having a flat bottom part is constituted of a flexible material such as plastic, and an ink lead-out pipe 2, an ink introducing port 3 and a stirrer 4 for magnetic stirring are provided. A membrane 6 is provided to the holding stand 7 in the introducing pipe 2 to bring said pipe 2 to a sealed state and, at the time of use, the membrane 6 is cut by a rotary cutter 8 to allow the pipe 2 to communicate with a printer side through an ink supply port 12. Since the main body 1 is flexible, the container shrinks and deforms with the consumption of ink to hold a hermetically sealed state. further, since the bottom part is flat, a stirring property is well when the container is placed on a magnetic indirect stirrer.

However, when comparing inkjet recording and inkjet textile printing, the former uses an extremely small amount of ink, while the latter consumes a large amount of ink.As a result, the functions required of the ink container are also significantly different. . Therefore, it is inappropriate to use an ink container used in an inkjet recording method as is for inkjet printing.

Especially from the perspective of maintaining ink quality, changes in ink concentration due to evaporation of water, generation of relatively large aggregated particles of dye due to dry adhesion of ink in the space in the ink container and peeling off of dry matter, and discharge due to these aggregated particles. There are problems such as clogging of the orifice and unrestricted dyeing, especially non-uniformity of ink concentration between the upper and lower layers, which occurs with water-insoluble or poorly soluble dye inks, so-called disperse dye inks.

Although the shape of the container body 1 is a rectangular parallelepiped in the illustrated one,
The shape is not limited to this, and the cross section may be triangular, pentagonal, or even circular. However, when filling the container of the present invention with ink and supplying this ink to an inkjet printer, it is necessary to stir the ink inside to keep it homogeneous. is a stirrer 4 for indirect magnetic stirring (
For example, it has an iron core and is coated with polyethylene, Teflon, etc. ) is stored, the container body (1) is placed on a magnetic indirect stirrer, so-called stirrer, and the stirrer 4 is rotated by the operation of the stirrer. For this purpose, when the container body 1 filled with ink is placed on a stirrer, the bottom surface of the container body 1 must be flat, but since the container body 1 is flexible as described above, for example, the bottom surface of the container body 1 must be flat. Even if the main body 1 has a circular cross section, the gravity of the filled ink makes the bottom surface flat and stirring can be performed without any problem.

To fill the container body 1 with ink, first remove the air inside the container body using a suction pump. Then, ink is injected from the ink inlet 3, and when a predetermined volume has been introduced, the ink supply is stopped and the tip of the ink inlet 3 is melted and sealed using a heat sealing machine. The ink introduction port 3 may be blocked by other means such as using a pinch cock, but since the container of the present invention is mainly disposable, it is preferable that the degree of sealing is low.

The ink outlet tube 2 is airtightly attached to the container body 1 by an attachment ring 5. A thin film 6 is held on the inner wall of the ink outlet tube 2 by a holding table 7 in the middle of the tube portion of the ink outlet tube 2, and this thin film 6 completely blocks off the channel of the ink outlet tube 2. Therefore, the inside of the container body 1 is kept in a sealed state.

To extract the ink from the container body 1, the thin film 6 is cut by a rotary cutter 8. That is, the tube end of the ink outlet tube 2 is closed by a disk-shaped rotary plate 9 that constitutes the cutter 8, and this rotary plate 9 is located at the center of a zero-rotation plate 9 that is rotatably mounted in the circumferential direction. A rod-shaped rotating shaft 10 protrudes in the vertical direction, and a bent blade 11 is attached to the tip thereof. rotating plate 9 to 18
Upon rotation 0', the blade 11 rotates from the position shown in solid lines to the position shown in dotted lines 11' in FIG. 2, thereby cutting the membrane 6.

However, since the container of the present invention has a sealed structure as is clear from the above, ink is transferred to the printer by suction from the inkjet printer, and the amount of ink in the container body 1 decreases according to the transferred amount. However, since the container body 1 is made of a flexible material, the entire container body 1 deflates as the ink volume decreases. That is, even if the amount of ink in the container body 1 decreases, outside air will not enter the container body. Therefore, in the container of the present invention, even while the container is filled with ink and stored, it can also be used in an ink printer. Even while the ink is being sent, the ink is not exposed to the outside air and is kept in a sealed state from beginning to end.

When the ink filled in the ink is stirred by the stirrer for magnetic indirect stirring housed inside, when placed on the magnetic indirect stirrer, the bottom surface becomes flat and stirring is carried out effectively. Not only is this possible, but when ink is fed from the container body to the printer, due to the container body having a sealed structure, the container body shrinks and deforms due to the amount of ink drawn out, and a space is created inside the container body. First, the same full state as when filling with ink is always maintained.

(b) The container body has a sealed structure, and no space is left inside the container body during the period when it is filled with ink and stored, and during the period when ink is supplied to the printer as described above. Since the ink can be left out, the quality of the ink can be maintained stably over a long period of time, and ejection from the orifice is stable even during inkjet printing.
