摘要： An object is to identify an abnormal mounted state of a liquid supply unit to a liquid ejection apparatus. There is provided a liquid supply unit configured to supply a liquid to a liquid ejection apparatus that comprises a first electrode assembly including a first electrode and a second electrode; an engagement structure; and a mounting structure which the liquid supply unit is mounted to. The liquid supply unit comprises a liquid supply portion; an engaged structure configured to be engaged with the engagement structure in a mounted state and thereby restrict a motion of the liquid supply unit in a first direction that is a direction of dismounting the liquid supply unit; and an electrically conductive portion provided in the engaged structure. The electrically conductive portion is configured to come into contact with the first electrode and the second electrode in an engaged state that the engaged structure is engaged with the engagement structure, so as to provide electrical continuity between the first electrode and the second electrode and cause the liquid ejection apparatus to detect mounting of the liquid supply unit to the liquid ejection apparatus.

摘要： An ink refilling container includes a bottle and a cap. The bottle includes an ink outlet forming portion including an ink outlet and a valve. The valve has valve segments segmented by slits. The cap includes a top portion, which faces the ink outlet when the cap is put on the bottle. A protruding portion extending in the central axis direction is provided at the center of the top portion. An annular-shaped sealing portion is provided on the top portion radially outside the protruding portion. The radius of the protruding portion is less than the length of the slit. In a sealed state wherein the cap is in thread engagement with the bottle and wherein the sealing portion seals the ink outlet, the tip end of the protruding portion is inserted in the inside of the bottle through the slits at the center region of the ink outlet.
