Abstract: A cartridge includes: a case; an accommodation part inside of the case; a liquid leading-out port; a cartridge side electrical connection part; and a cartridge side fixation structure. Engagement of the device side fixation structure and the cartridge side fixation structure restricts moving the case in a state of being imparted with the force directing to −Z direction. The cartridge side fixation structure and the cartridge side electrical connection part overlap with each other at least in a part when the cartridge is viewed in Z directions. A width of the cartridge in the Z direction is smaller than a width in Y direction and a 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: 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: The liquid container has a spacer member provided in the liquid storage portion. When three directions orthogonal to each other are assumed to be a D direction, a T direction, and a W direction, in the D direction, a direction from a liquid outlet portion toward the other edge portion of the bag is assumed to be a +D direction, and the opposite direction to the +D direction is assumed to be a −D direction, and a direction in which the dimension of the outer shape of the liquid container is smallest is assumed to be the T direction, and the spacer member has, on the +D direction side, a face inclined such that the dimension in the T direction of the spacer member increases from the +D direction side toward the −D direction side.
