FIG. 1 is an embodiment of the present invention showing an ink cartridge 20 composed of a cartridge case 10, a detection lever 4, an ink bag 7, a sheet-like absorbing material 6, and the like. The ink bag 1 to which the outlet 1a is welded by heat sealing is fixed to the cartridge case 10 with adhesive or double-sided adhesive tape, and a thin detecting plate 5 made of metal or plastic is adhered to the upper part. The outlet 1a is also fixed to the cartridge case 10. The detection lever 4 is rotatably supported at two points in the depth direction of A of the cartridge case 10 in the drawing, and the tip 4a is in contact with the detection plate 5 by its own weight or by a spring. Further, the tip 4b is connected to the detector 30 fixed to the cartridge holder by a method not shown.
The recording apparatus detects that the ink has run out, and alerts the recording apparatus to replace the ink cartridge. On the upper part of the ink cartridge 20, an upper lid 11 having an air hole 11a and an inner lid 12 for isolating the absorbent 6 from the ink bag 1 are seal-welded. Further, a waste liquid port 13 for receiving waste ink is provided in a part of the cartridge case 10. A needle 14 for discharging waste ink into the ink cartridge when the ink cartridge is mounted on the printer body is inserted into the waste liquid port 13. A needle hole for discharging waste ink is formed at the tip of the needle 14.
The waste liquid port 13 covers the cartridge case 10
Is formed so as to protrude inside. And this waste outlet 13
Are arranged in a stacked manner so as to sandwich the sheet from above and below. Therefore, the needle 14 does not directly pierce the ink absorbing material 6, the load is reduced when the ink cartridge 20 is inserted into and removed from the printer main body, and the damage of the needle, which is a fixed part, is prevented, and the damage of the ink absorbing material is prevented. Is prevented, and the problem that the needle hole is clogged with the debris of the absorbing material and the discharge of the waste liquid is hindered is prevented. Further, since the sheet-like ink absorbing material 6 is laminated and disposed so as to sandwich the waste liquid port 13 projecting into the inside from above and below, the waste ink is prevented from being scattered and discharged over the entire surface of the sheet-like ink absorbing material. The ink can be efficiently absorbed, and the leakage of the ink to the outside of the cartridge can be prevented. Further, when the waste liquid port 13 is sandwiched by the ink absorbing material 6, that is, a space is naturally formed in the portion where the ink is discharged from the waste liquid port 13, and when a large amount of waste ink is discharged, Since the waste ink can be temporarily taken in, the collection of the waste ink does not stagnate. Further, since this space is surrounded by the absorbing material 6, the taken ink does not leak to the outside of the cartridge, and the ink is quickly absorbed. Absorbed by the absorbing member 6.

More ink is supplied, and the waste ink is collected through the waste liquid port 13. At this time, the waste ink jetted vigorously is sprayed near the center 6c of the absorbent 6, and then permeates toward the outer periphery. When the ink in the ink bag 1 decreases due to printing by the ink jet printer, the tip 4b of the detection lever 4 comes into contact with the lever of the detection lever 30 as shown in FIG. .

By arranging the sheet-shaped ink absorbing material on the waste liquid port so as to sandwich the ink absorbing material from above and below, the needle is protected by the waste liquid port and does not directly pierce the ink absorbing material. The load is reduced when inserting / removing the ink cartridge, preventing damage to the needle, which is a fixed part, and also preventing damage to the ink absorbing material. Is prevented. Furthermore, since the sheet-shaped ink absorbing material is laminated and arranged so as to sandwich the waste liquid port protruding into the inside from above and below, the waste ink is discharged over the entire surface of the sheet-shaped ink absorbing material while suppressing the scattering of the discharged ink. The ink can be efficiently absorbed, and leakage of the ink to the outside of the cartridge can be prevented. Also, by simply sandwiching the waste liquid port with the ink absorbing material, a space can be naturally formed near the waste liquid port with a simple configuration without increasing the number of parts and the manufacturing process, and ink discharged using this space can be temporarily used. To prevent waste ink from being collected, and this space is surrounded by an absorbing material, so that the taken-in ink is quickly absorbed by the ink absorbing member without leaking to the outside of the cartridge. You.
