An ink refill container includes a container main body including an ink storage chamber, an ink outlet-forming portion provided on an end portion of the container main body forming an ink outlet that allows the ink to flow out from the ink storage chamber, and a valve provided in the ink outlet-forming portion configured to openably seal the ink outlet, in which the ink outlet-forming portion includes a positioning portion on an outer side of the ink outlet-forming portion. in which the positioning portion is closer to the container main body than the valve is to the container main body in a central axis direction of the ink outlet, and in which the positioning portion partially abuts against an ink tank when the valve is opened for refilling the ink to the ink tank, to thereby position the valve relative to the ink tank.

Ink refill container, ink refill system, and ink refill adapter

An ink refill container configured to refill an ink tank with ink includes a container main body having an ink chamber; an ink outlet forming portion provided at an edge of the container main body including an ink outlet configured to allow ink to flow out from the ink chamber; a valve provided in ink outlet forming portion and configured to seal the ink outlet in an openable and closable manner; and a positioning structure configured to abut on part of the ink tank and position the valve relative to ink tank when valve is opened. The positioning structure has a positioning surface located on an opposite side to a container main body side where the container main body is located, across the valve and extends in a direction intersecting with a center axis of the ink outlet.

Ink refill container and ink refill system

Convenience of an ink bottle and a bottle set is improved. An ink bottle includes: a container portion that contains ink; a guiding portion that is formed in one end portion of the container portion, and includes an outflow port from which the ink in the container portion flow out; and a cover that covers at least an end portion of the container portion on the opposite side of the guiding portion.
