Abstract
An ink cartridge comprises an upper cover, and the inside of an inner frame portion of the upper cover is partitioned into a groove and a waste ink storing portion by a wall portion. A waste ink absorber is accommodated in the waste ink storing portion, and the inner frame portion is sealed with a film in this state so that a passage and a waste ink storing chamber are formed. The opening of a lower cover accommodating an ink pack therein is sealed with the upper cover thus constituted so that the ink cartridge is formed. Even if the ink cartridge is turned in various directions such that any surface of the lower cover acts as a lower surface, the position of the ink pack in the ink cartridge is always set to be higher than the liquid level of the ink in an ink bag.
