Liquid cartridge having structure for suppressing leakage of liquid deposited on seal and cap

A liquid cartridge configured to be detachably attached to a cartridge receiving portion in an attached state, the liquid cartridge comprising:

• a main body defining therein a storage chamber for storing liquid;
• a liquid channel extending in an extending direction to have an outlet that is open to an outside of the liquid cartridge, the liquid channel having an inner peripheral surface defining an internal space in communication with the storage chamber;
• a seal positioned in the internal space of the liquid channel and in contact with the inner peripheral surface to provide a liquid-tight seal therebetween, the seal having a first through-hole penetrating through the seal in the extending direction;
• a valve configured to open and close the first through-hole, the valve being positioned in the internal space of the liquid channel and closer to the storage chamber than the seal is to the storage chamber in the extending direction;
• and
• a cap positioned closer to the outlet of the liquid channel than the seal is to the outlet of the liquid channel, the cap having a second through-hole penetrating through the cap in the extending direction and in communication with the first through-hole, the second through-hole defining an axis extending in the extending direction,
• wherein the inner peripheral surface of the liquid channel, the seal, and the cap define a liquid retaining space at a position between the seal and the cap, and
• wherein the cap has a cap opening in communication with the liquid retaining space and the outside of the liquid cartridge, an entirety of the cap opening being positioned below the axis of the second through-hole in the attached state of the liquid cartridge.
