ABSTRACT:
An ink cartridge has a cover that is in intimate contact with an ink tank around the ink injection port and having an opening portion at a position corresponding to the ink injection port, and the protection cap held slidably between the cover and the ink tank for opening/closing the opening portion. When the protection cap is closed, the ink injection port is tightly closed. Also, the protection cap of the ink cartridge has a lever projecting from the opening portion of the cover. An ink cartridge holder fixed to the recording apparatus for loading the ink cartridge thereon has claws engaged with a lever of the ink cartridge in the loading condition. When the ink cartridge is loaded, the protection cap is opened by the claws.
