Abstract
An ink cartridge includes ink chambers storing ink, a sealing member sealing the ink chambers provided with ink injection openings injecting ink into the ink chambers and air inflow openings through which the ink chambers communicate with an outside of the ink chambers, a cover member forming air inflow passageways between the air inflow openings and the outside of the ink chambers in cooperation with the sealing member and sealing the ink injection openings, an ink blocking part first blocking the ink from being discharged through the air inflow passageways in cooperation with the air inflow openings, and an ink storage part storing the ink passing through the air inflow openings and the ink blocking part to prevent the ink from being discharged through the air inflow passageways. The ink cartridge is provided with the ink blocking part and the storage part, so that suppression of ink evaporation is maximized, and the air inflow passageways maintaining a negative pressure are prevented from being clogged with flowing-back ink caused by shocks or movements of a printer during carrying of the printer or an external temperature rise, or with an inflow of minute dust and so on.
