Abstract: An ink refill container includes a bottle and a cap. The bottle includes: an ink outlet forming portion having an ink outlet and an outer peripheral portion with a first screw thread; and a valve with a valve member in the ink outlet. The cap includes: a trunk having a second screw thread engageable with the first screw thread; a top portion; and a projection. The projection is configured to move and push the valve member to open the valve member when the cap is rotated in a first direction in which engagement between the first screw thread and second screw thread is cancelled. The projection is configured to relatively rotate in the first direction and move away from the valve member to close the valve member when the cap is rotated in a second direction in which the first screw thread engages with the second screw thread.
