Ink replenish container

An ink replenish container for replenishing an ink to an ink tank of a printer, comprising:

• a container main body configured to store the ink;
• an ink outlet formation member, attached to a front end side of the container main body, to form an ink outlet;
• and
• a cap attachable to a front end side of the ink outlet formation member,
• wherein the ink outlet includes an outer circumferential surface and an inner circumferential surface located inward of the outer circumferential surface, the inner circumferential surface surrounding an opening through which the ink passes,
• the cap includes a first protrusion that is configured to contact with the outer circumferential surface of the ink outlet to form a first exit seal portion, and a second protrusion that is configured to contact with the inner circumferential surface of the ink outlet to form a second exit seal portion, and
• wherein a distance from a bottom of the container main body to a back end position of the second exit seal portion on the container main body side is shorter than a distance from the bottom of the container main body to a back end position of the first exit seal portion on the container main body side.

• an exit valve attached to the ink outlet at a position that is closer to the back end of the container main body than the opening of the ink outlet is,
• wherein the ink outlet includes an outer circumferential surface and an inner circumferential surface located inward of the outer circumferential surface, the inner circumferential surface surrounding an opening through which the ink passes,
• the cap includes a first protrusion that is configured to contact with the outer circumferential surface of the ink outlet to form a first exit seal portion, and a second protrusion that is configured to contact with the inner circumferential surface of the ink outlet to form a second exit seal portion,
• the ink outlet includes a third protrusion that is configured to contact with the exit valve to form a third exit seal portion, and
• in a radial direction with a center axis of the ink replenish container being an axial center, the second exit seal portion is formed at a position closer to the center axis of the ink replenish container than the third exit seal portion is.
