An ink cartridge with an ink impregnated foam element contained therein is provided. A first opening is provided in the ink cartridge and is sealed by a cover. This cover is pierced by a tubular connector piece when the ink cartridge is inserted into a printing head. The tubular connector piece forms a seal with a sealing surface of the first opening which is formed below the cover to prevent any leakage of ink. A second opening is also formed in the ink cartridge to allow air to be delivered to the interior of the ink cartridge.
