A seal part for an ink cartridge of an inkjet printer including a seal end for sealing an ink outlet port of the ink cartridge is provided. The seal part is column-shaped, a cylindrical cavity exists inside the seal part, and a diameter of the cavity is greater than a diameter of an ink supply needle of the printer. The seal end for sealing the ink output port of the ink cartridge is a cylindrical surface, or is a cylindrical surface having at least a circle of sealing flange. One end surface is a closed plane for preventing the ink from flowing out from the ink outlet port after the ink cartridge is detached from the printer, and the other end surface is a plane with an aperture in the center. The size of the aperture is adequate to seal the ink supply needle of the printer. The seal part seals the ink supply needle of the printer after the ink cartridge is installed in the printer, and prevents the ink leakage after the ink cartridge is detached from the printer. |
