Abstract
A liquid cartridge includes a main body, a liquid channel, a seal, a valve, and a cap. The liquid channel extends in an extending direction and has an inner peripheral surface defining an internal space communicating with a storage chamber. The seal contacts the inner peripheral surface of the liquid channel for liquid tight seal therewith. The seal has a first through-hole penetrating therethrough in the extending direction. The valve is positioned closer to the storage chamber than the seal is. The cap is positioned closer to an outlet of the liquid channel than the seal is. The cap has a second through-hole penetrating therethrough in the extending direction and defining an axis extending in the extending direction. A space is defined by the inner peripheral surface of the liquid channel, the seal, and the cap. The cap has a cap opening positioned below the axis of the second through-hole.
