1. A liquid cartridge comprising:
a liquid chamber configured to store liquid therein; an air communication portion configured to selectively bring the liquid chamber into communication with the atmosphere outside the liquid cartridge; and a capillary portion having a first end configured to be in communication with the liquid chamber and a second end configured to be in communication with the atmosphere outside the liquid cartridge, wherein the capillary portion is configured to move the liquid from the first end to the second end therethrough by capillary force when the liquid chamber is brought into communication with the atmosphere outside the liquid cartridge via the air communication portion; wherein the second end of the capillary portion is configured to be in communication with the atmosphere outside the liquid cartridge via the air communication portion, wherein the air communication portion comprises an air communication chamber having a first opening and a second opening, wherein the liquid cartridge further comprises a first closing member closing the first opening, such that communication between the air communication chamber and the outside of the liquid cartridge is blocked, and a second closing member closing the second opening, such that communication between the air communication chamber and the liquid chamber is blocked; and wherein the second end of the capillary portion is connected to the air communication chamber between the first opening and the second opening.
