PROBLEM TO BE SOLVED: To keep an ink airtight to prevent the ink from evaporating and leaking, and thereby supply the ink efficiently to a printer head and at the same time, make a used ink tank easily recoverable by interposing an O-ring in the outwardly oriented cylindrical part of an ink supply part to fit a cover airtightly. SOLUTION: An ink supply part 12 is provided at the bottom part 11 of an ink tank 1, and a porous body for connection 13 is fitted into a through hole 121 in the ink supply part 12. In addition, an O-ring 123 is interposed on the outside of an outwardly oriented cylindrical part 122 to engage a cup-like cover 14 encircling the porous part 13 in freely detachable manner. Further, when the ink tank 1 by mounting it on a printer, the cover 14 is detached from the cylindrical part 122 to face the cylindrical part 122 to an ink supply device 20. In addition, an ink supply needle 21 is introduced into a tapered blind hole 133 of the porous body 13, and the porous body 13 is slightly pushed up by the ink supply needle 21. Thus the ink tank 1 is mounted on a printer. |
