The ink cartridge comprises a container formed with an inner space and a port enveloped by an annular flange, a sealing mechanism used to fit in the annular flange, and an ink supply needle used to connect the inner space and output the ink. Pluralities of capillary portions are formed on the inner sidewall of the port so as to keep the filter with ink. A positioning hole indented from one end of the sealing mechanism is used to align the ink supply needle, and a recess is provided at another end of the sealing mechanism so as to connect the inner space of the container. When the sealing mechanism has been fully inserted with the ink supply needle, the sealing mechanism clamps the ink supply needle and the ink received in the container can be smoothly transmitted via the ink supply needle. When the ink cartridge is pulled out of the ink supply needle, the piercing hole of sealing mechanism is rapidly converged and sealed the port, and then the stored ink can be kept in the container with no leakage.
