Abstract

(57) [Summary] [Purpose] To prevent ink from leaking outside the ink cartridge and to prevent ink from dripping from the ink supply needle. By providing the absorber 4 on the front surface of the coupling member 3, the leakage of the ink 1 from the coupling member 3 is absorbed, and the ink leakage to the outside of the ink cartridge 5 is prevented, and
The ink on the outer peripheral portion of the ink supply needle 6 is wiped and absorbed to prevent the ink from dripping onto the device.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a replaceable ink cartridge containing ink, and more particularly to an ink cartridge useful for a droplet jet recording apparatus.

[0002]

[Prior art]

 Conventionally, ink is contained in a container, and ink is supplied by inserting an ink supply needle into a connecting member provided in the container. The ink container is replaced by replacing the ink cartridge containing the ink container.

[0003]

[Problems to be solved by the device]

 However, when the ink cartridge is removed, the ink supply needle leaves a through hole in the connecting member, so that ink leaks from the through hole. It is generally known that ink mainly contains organic solvents, polyhydric alcohols, or water. If the ink cartridge is made of a polymer material such as plastic, when the ink leaking from the connecting member comes into contact with the ink cartridge, the ink cartridge is deformed or melted, and the ink leaks to the outside of the ink cartridge. Alternatively, if the ink cartridge is made of a metal material, it causes corrosion of the ink cartridge and causes ink leakage to the outside of the ink cartridge. In addition, when the ink cartridge is removed, ink is attached to the outer peripheral portion of the ink supply needle, and when the ink cartridge is mounted in this state, the ink is pushed to a part of the outer peripheral portion of the ink supply needle by the connecting member. Each time the ink cartridge is repeatedly replaced, ink is accumulated in a part of the outer peripheral portion of the ink supply needle, causing ink dripping from the ink supply needle to the droplet jet recording device.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides an absorber in front of a connecting member in an ink cartridge containing an ink containing member and a connecting member provided in the containing member.

[0005]

[Action]

 In the ink cartridge of the present invention, the absorber on the front surface of the coupling member absorbs the leakage of the ink from the coupling member, and when the ink cartridge is attached or detached, the ink adhering to the outer peripheral portion of the ink supply needle can be wiped and absorbed. .

[0006]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view of an embodiment of the present invention seen from above. In FIG. 1, an absorber 4 for absorbing the ink 1 is provided on the front surface of a coupling member 3 provided in the container 2 for coupling the container 2 containing the ink 1 and the ink supply needle 6. ing. The absorber 4 is housed in the gap between the coupling member 3 and the ink cartridge 5. FIG. 2 is a cross-sectional view seen from the upper surface in the vicinity of the absorber 4 when the ink cartridge 5 is mounted. The ink supply needle 6 first penetrates the absorber 4. Further, the central portion 3a of the coupling member 3 is pierced to cause the tip of the ink supply needle 6 to enter the inside of the container 2. At this point, the ink 1 can be supplied. At this time, the absorber 4 absorbs the excess ink adhering to the outer peripheral portion of the ink supply needle 6 by wiping it off, so that ink may not be accumulated on a part of the outer peripheral portion of the ink supply needle 6. Absent.

Next, when removing the ink cartridge 5, the excess ink adhering to the outer peripheral portion of the ink supply needle 6 inside the absorber 4 is wiped off and absorbed. Since no ink remains on the outer peripheral portion of the ink supply needle 6 after the ink is taken out, even if the ink cartridge 5 is mounted again, the ink does not remain on a part of the outer peripheral portion of the ink supply needle 6.

Further, when the ink cartridge 5 is removed, the ink supply needle 6 leaves a through hole in the connecting member 3, so that leakage of the ink 1 occurs from the through hole, but the absorber 4 on the front surface of the connecting member 3 does. Thus, the leakage of the ink 1 from the coupling member 3 is absorbed.

[0009]

[Effect of device]

 As described above, according to the present invention, by absorbing the ink leakage from the coupling member, it is possible to prevent the ink cartridge from being deformed, dissolved or corroded, and to prevent the ink leakage to the outside of the ink cartridge. Further, since the ink around the outer peripheral portion of the ink supply needle is wiped and absorbed, it is possible to prevent the ink from dripping into the device using the ink cartridge.
