The positioning structure has a positioning surface 84 that is located on an opposite side to a container main body side where the container main body is located, across the valve and that is extended in a direction intersecting with a center axis 85 of the ink outlet.
1. An ink refill container configured to refill ink into an ink tank that has an ink inlet flow path portion and an ink chamber arranged to communicate with the ink inlet flow path portion, the ink refill container comprising:
a container main body provided to include an ink chamber configured to contain therein ink, which is to be refilled to the ink tank;
an ink outlet forming portion provided at an edge of the container main body to include an ink outlet configured to allow the ink to flow out from the ink chamber;
a valve provided in the 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 the ink tank when the valve is opened, wherein
the ink outlet is formed in a tubular portion that is part of the ink outlet forming portion,
the positioning structure includes a positioning surface that is provided to be opposed to an outer face of the tubular body across a clearance and that is extended in a direction intersecting with a center axis of the ink outlet, and
the positioning surface abuts on the part of the ink tank, when the ink inlet flow path portion of the ink tank is inserted into the ink outlet to open the valve.
2. The ink refill container according to claim 1 ,
wherein an area of the positioning surface abutting on the part of the ink tank on a side farther from the ink outlet in the direction intersecting with the center axis of the ink outlet is larger than an area of the positioning surface abutting on the part of the ink tank on a side closer to the ink outlet.
3. An ink refill container configured to refill ink into an ink tank that comprises:
an ink storage chamber capable of storing ink;
a needle that is extended and includes a flow path for communicating an inside and outside of the ink storage chamber;
a receiving surface that is extended in a direction intersecting with an extended direction of the needle at a position outside of a leading end of the needle in the extended direction of the needle; and
a recess that is open in the extended direction of the needle in an area outside of the needle in a direction intersecting with the extended direction of the needle, wherein the recess is formed as a pair of holes provided to be continuous to an ink inlet so as to sandwich the ink inlet with the needle arranged at a center of the ink inlet, and the receiving surface includes the ink inlet and an opening edge of the recess,
the ink refill container comprising:
a container main body provided to include an ink chamber configured to contain therein the ink; and
an ink outlet forming portion provided at an end portion of the container main body to include an ink outlet configured to allow the ink to flow out from the ink chamber,
wherein the ink outlet forming portion has a projection that is insertable in the pair of holes of the recess when the needle is inserted into the ink outlet, in an area outside of the ink outlet in a direction intersecting with a direction in which the needle is inserted, and
wherein the projection comprises a leading end face, which includes, when viewed in a center axis direction of the ink outlet, a first portion extending in a radial direction from a center of the ink outlet, and a second portion extending from an end outside of the first portion in the radial direction, in a direction intersecting with the radial direction.
4. The ink refill container according to claim 3 ,
wherein, when viewed in the center axis direction of the ink outlet, the first portion and the second portion are in an approximate T shape.
5. The ink refill container according to claim 3 ,
wherein the ink outlet forming portion comprises a small diameter section having the ink outlet, and a clearance is formed between the small diameter section and the projection.
6. The ink refill container according to claim 3 , further comprising
a valve that is provided in the ink outlet forming portion and is able to open and close the ink outlet,
wherein, when the projection is inserted into the recess, the valve is opened by the needle.
