Abstract: A liquid container into which ink is injected comprises a liquid container body configured to contain a liquid therein; and a liquid supply assembly located on one end portion of the liquid container body. The liquid supply assembly has a liquid supply port provided to supply the liquid to a liquid consuming apparatus. The liquid supply port is formed to face in an intersecting direction that intersects with the direction of gravity and to be protruded in the intersecting direction from the one end portion when the liquid supply assembly is supported such as to be located above the liquid container body in the direction of gravity. A liquid injection member is inserted into the liquid supply port, and the liquid is injected into the liquid container body. The liquid supply port is then arranged to be protruded in the intersecting direction, and the liquid injection member is detached from the liquid supply port.

Abstract: There is provided a technology which can improve the mounting posture of a liquid ejection apparatus when mounted to a liquid container. The liquid container is flexible and includes a storage portion configured to store the liquid and a connection member. The connection member is provided with a liquid outlet which is inserted with a liquid introduction portion, a container-side electrical connector which makes electrical contact with an apparatus-side electrical connection unit while receive at least +Z direction force from the apparatus-side electrical connection unit, a first receiver configured to receive a first positioning portion, a second receiver configured to receive a second positioning portion, and a recess which houses a protrusion of the case. The recess and the container-side electrical connector are formed at positions which at least partially overlap each other when viewed from a Z direction in a mounting state. In the mounting state, the width of the liquid container in the Z directions is larger than the width in the Y directions and the width in the X directions.

Abstract: A liquid containing member that can supply a liquid having a uniform concentration of a precipitating component to a liquid ejecting portion is provided. A liquid containing member includes: a liquid containing portion that can contain ink; a liquid supply port for supplying the ink contained in the liquid containing portion to a liquid ejection head; and a communication channel that is in communication with the liquid containing portion and the liquid supply port. The communication channel has a first end that is positioned at a lower end on the gravity direction side in the liquid containing portion and can suck the ink, and a second end that is positioned closer to the anti-gravity direction side than the first end is, and can suck the ink, in an in-use state in which the ink is supplied from the liquid supply port to the liquid ejection head.

Abstract: A liquid container includes a liquid containing bag which contains a liquid and has at least two sheets of flexible film, and a liquid supply portion which supplies the liquid to a liquid consuming apparatus. The liquid supply portion is welded with the two sheets of film at one end of the liquid containing bag, and has a liquid supply path, a first chamber, and a second chamber. The first chamber communicates with the liquid supply path and an interior of the liquid containing bag. The second chamber communicates with the interior of the liquid supply portion. The first chamber is partitioned by a first rib, and the second chamber is partitioned from the first chamber by a second rib separated from the first rib. The first chamber communicates with the second chamber via a gap between the second rib and the one sheet of film.
