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

When a known lid member was merely applied to a bottle that contains ink, there was room for improvement in terms of the operation of the lid member and the way how to bring attention to the handling thereof. A bottle set is provided that includes: a bottle that includes an ink container that contains ink, and an outflow port through which the ink in the ink container flows out to the outside; and a lid member that is configured to attach to and detach from the bottle, and is configured to cover the outflow port in a state of being attached to the bottle. The lid member includes a colored portion that has optical transparency and is colored with a color corresponding to a type of the ink contained in the ink container in at least a portion of the lid member.

Bottle set and bottle

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.

Ink replenish container

The printing system includes a liquid supply container that stores a liquid; a printing device that receives a liquid supplied from the liquid supply container and performs printing; an imaging device that acquires image information including at least a part of the liquid supply container; an acquisition section that acquires reference information; a determination section that collates the image information with the reference information and determines whether or not the liquid is allowed to be supplied according to a collation result; and a control section that controls the printing device according to the determination.

Printing system

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.
