摘要： An inkjet cartridge includes a cartridge body provided with an ink storing space to store ink therein, a lid mounted on an upper portion of the cartridge body to seal the cartridge body, a head chip mounted on a lower portion of the cartridge body to eject the ink stored in the cartridge body, and an elastic member mounted on the cartridge body to absorb an impact transmitted to the head chip. Therefore, an impact applied from an exterior of the cartridge body is blocked and absorbed by the elastic member before the impact is applied to the head chip. As a result, a crack phenomenon of the head chip due to the external impact is fully prevented.

摘要： An ink cartridge including an ink storage chamber in which ink is stored, a cover to cover the upper portion of the ink storage chamber and a head to eject ink droplets in the ink storage chamber onto a recording medium, wherein the cover includes an inner cover to cover the upper portion of the ink storage chamber and an outer cover that seals the ink storage chamber and the inner cover, and is positioned at a predetermined distance above the inner cover. Also provided are plates to form zigzag air passages by blocking a space between the inner cover and the outer cover. With the ink cartridge according to the present invention, it is possible to satisfactorily suppress the backward flow of ink contained in an ink storage chamber due to overheating of or careless treatment of the ink cartridge. Even if ink flows backward from the ink storage chamber, it is stored in an ink storage space, thus preventing the clogging of an air passage. Further, air entering the ink storage space is filtered, passing through the air passage, and additional components are not required to seal up an opening to which ink is supplied. For this reason, manufacturing costs can be reduced and a manufacturing process can be simplified.
