    Abstract: An ink replenishment container includes a container main body, an ink outlet forming section, and a valvehaving elasticity. An exterior of the valve is circular in plan view and has two or more slits that extend from a center toward a circumference so as to be joined at the center, two inclined surfaces toward the slit are formed for each of the slits so as to interpose the slit therebetween like a valley when viewed from the ink outlet side, and when a pressure difference positive in a direction from an inside of the ink replenishment container to an outside thereof acts on inner sides of the two inclined surfaces, the slits are closed, and when a pressure difference positive in a direction from the outside of the ink replenishment container to the inside thereof acts on outer sides of the two inclined surfaces, the slits are opened.

    Abstract: There is provided an ink replenishment container for replenishing ink into an ink tank via an ink inlet flow path member having a plurality of flow paths, the ink replenishment container including a container main body, an ink outlet forming portion, and an outlet valve unit. The outlet valve unit includes a valve housing mounted to provide a gap with an inner peripheral surface of a tubular portion in the tubular portion, a sealing member, and a valve body movable between a valve close state in contact with the sealing member and a valve open state separated from the sealing member. The valve body has a partition contact portion capable of contacting a partition of the ink inlet flow path member. The valve housing has a through-hole that communicates with the gap, and the through-hole communicates with the ink inlet flow path member in the valve open state.

    Abstract: An ink replenish container comprises a container main body that is able 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. 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.
