Abstract:
There is provided a liquid cartridge attachable to an attachment portion. The attachment portion includes: a holder providing an accommodation space; a tube formed with an opening; a valve movable between an open position opening the opening and a closed position closing the opening; a protrusion protruding from the valve toward the accommodation space; and a spring urging the valve toward the closed position. The liquid cartridge includes: a liquid chamber; a communication passage extending from the liquid chamber in a first direction to have an open end; a sealing member fitted to the communication passage; and a surface positioned closer to the liquid chamber than the sealing member to the liquid chamber in the first direction. In an attached state, the tube extends through the open end and sealing member, the opening is positioned in the communication passage, and the surface is in contact with the protrusion and tube.

Claim (Index 14):
A system comprising:\n an attachment portion; and a liquid cartridge attachable to the attachment portion, the attachment portion comprising:\n a holder providing an accommodation space for accommodating therein the liquid cartridge in an attached state; \n a tube formed with an opening opening toward the accommodation space; \n a valve movable between an open position opening the opening and a closed position closing the opening; \n a protrusion protruding from the valve toward the accommodation space, the protrusion protruding into the accommodation space through the opening in the closed position of the valve; and \n a spring urging the valve toward the closed position, \n the liquid cartridge comprising:\n a liquid chamber for storing therein liquid; \n a communication passage for communicating the liquid chamber with an outside of the liquid cartridge, the communication passage extending from the liquid chamber in a first direction to have an open end in the first direction; \n a sealing member fitted to the communication passage; and \n a surface facing the sealing member in the first direction, the surface being spaced away from the sealing member in the first direction, the surface being positioned closer to the liquid chamber in the first direction than the sealing member is to the liquid chamber in the first direction, \n wherein, in the attached state,\n the tube extends through the open end and the sealing member, \n the opening is positioned in the communication passage, and \n the surface is in contact with both the protrusion and the tube.
