Ink cartridge

An ink cartridge comprising:

• a body defining an ink chamber storing ink;
• a sealing member forming a side of the body to seal the ink chamber, and provided with a first inner wall defining an ink injection opening, through which the ink is injected into the ink chamber, and a second inner wall defining a first air inflow opening, through which the ink chamber communicates with an outside of the ink chamber;
• a cover member sealing the ink injection opening and the first air inflow opening of the seal member, and forming a passageway between the first air inflow opening and the outside of the ink chamber with the sealing member;
• and
• a wall disposed between the cover member and the seal member to surround the second inner wall to block the ink passing the first air inflow opening from being discharged to the outside of the ink chamber, and having a second air inflow opening to form a part of the passageway to allow external air to be introduced into the passageway from the outside of the ink chamber.

An ink cartridge comprising:

• a body defining a plurality of ink chambers storing corresponding ones of ink;
• a sealing member forming a side of the body to seal the ink chambers, and provided with a plurality of first inner walls defining respective injection openings, through which the corresponding ink is injected into corresponding ones of the ink chambers, and a plurality of second inner walls defining respective first air inflow openings, through which the ink chambers communicate with an outside of the ink chamber, respectively;
• a cover member sealing the ink injection openings and the air inflow openings of the seal member, and forming passageways between the air inflow openings and corresponding ones of the outside of the ink chamber with the sealing member;
• and
• a plurality of walls disposed to form corresponding ones of the passageways between the cover member and the seal member to surround respective ones of the second inner walls to block the ink passing corresponding ones of the air inflow openings from being discharged to the outside of the ink chamber, the walls having second air inflow openings to form a part of the passageways and allow external air to be introduced into the passageways from the outside, and isolating the passageways from each other.
