Abstract
A liquid cartridge includes: a cartridge body; a liquid supply portion; a sealing member having a through-hole; first and second valves; and first and second urging members. The liquid supply portion defines therein a liquid passage extending in a frontward direction and having an opening open frontward. The sealing member is provided on a periphery of the opening of the liquid supply portion, and has first and second surfaces those face rearward. The first and second valves are disposed in the liquid passage so as to be movable in the frontward direction and a rearward direction. The first valve is pressed by the first urging member to abut the first surface and interrupts communication between the through-hole and the liquid passage. The second valve is urged by the second urging member to abut the second surface and interrupts communication between the through-hole and an outside of the liquid supply portion.
