    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: There is provided a technique of improving the mounting position of a liquid container relative to a liquid ejection device. The liquid container configured to be mountable to and dismountable from a case of the liquid ejection device includes a bag-like member that has flexibility and that includes a containing portion provided to contain a liquid inside thereof; and connection member that is located at an end of the bag-like member. The connection member includes a liquid outlet configured such that a liquid introducing element of the liquid ejection device is inserted in the liquid outlet; a container-side electrical connecting structure configured such that a device-side electrical connecting structure of the liquid ejection device is connected with the container-side electrical connecting structure; and two guided elements configured such that at least respective parts of two guide elements of the case are fitted in the two guided elements in a state that the liquid container is placed in the case. In a mounting state that the liquid container is mounted to the liquid ejection device, the liquid outlet is located between the two guided elements, and the container-side electrical connecting structure is located between one of the two guided elements and the liquid outlet.

    Abstract: A liquid container comprises a liquid supply port provided in a bottom wall, a first chamber configured to contain a liquid, a second chamber configured to contain the liquid and to include at least one sub-chamber having a smaller dimension in the X direction than that of the first chamber, a partition wall configured to part the first chamber from the second chamber, and a connecting hole configured to connect the first chamber with the second chamber. The second chamber is connected with the liquid supply port, and the first chamber is connected with the liquid supply port via the connecting hole and the second chamber. The liquid contained in the first chamber is flowed from the connecting hole into the second chamber and is subsequently introduced through the sub-chamber to the liquid supply port.

    Abstract: A tank unit includes two or more liquid accommodating containers disposed in a row. Each of the liquid accommodating containers includes a main body having a concave shape defining a side opening and a film that blocks the side opening. The main body and the film at least partially define a liquid accommodating chamber for accommodating a liquid. The main body includes a facing wall that faces the film across the liquid accommodating chamber and has a wall larger than the side opening. The liquid accommodating containers are disposed such that the film of at least one of the liquid accommodating containers is covered by the facing wall of an adjacent one of the liquid accommodating containers.
