Abstract: A cartridge detachably mounted to a printing device cartridge mounting portion includes a second fixing structure including a groove guiding a first fixing structure, and a locking portion provided to the groove. The cartridge is brought from a cartridge insertion state to a cartridge mounting portion predetermined position by being moved along a horizontal direction to a mounting state in which the cartridge is mounted by being rotated and moved in a rotation mounting direction around a fulcrum which is a far side of the cartridge mounting portion in the insertion direction by receiving a force having a component in a downward direction of a gravity direction. The second fixing structure locks the first fixing structure in the mounting state and releases with the first fixing structure by receiving the force having the component in the downward direction of the gravity direction applied to the cartridge in the mounting state.

Abstract: A technique for preventing a decrease in an amount of liquid contained in a cartridge is provided. The cartridge includes a liquid containing portion and a liquid supply portion. The liquid supply portion is coupled to the liquid inlet portion due to rotational movement of a containing-portion-rear-wall side of the cartridge downward around a rotation fulcrum, which is located on the insertion direction side, of the cartridge mounting portion. In the insertion direction, a first distance between a liquid flowing-in port and a rear wall inner surface, which is an inner surface of a containing portion rear wall, is shorter than a second distance between the liquid flowing-in port and a front wall inner surface, which is an inner surface of a containing portion front wall.

Abstract: The liquid container is detachable from a case of a liquid ejection apparatus. The liquid container has a bag-shaped member that is flexible and has a storage portion for storing a liquid therein, and a connection member attached to the bag-shaped member. The connection member has a liquid introducing outlet into which a liquid introducing portion of the liquid ejection apparatus is inserted, a container-side electrical connection unit to which an apparatus-side electrical connection unit of the liquid ejection apparatus is connected, and a handle that pivots with respect to the connection member. In a state where the liquid container is arranged in the case, the handle is provided at a position exposed to the outside of the case, and when the liquid container is mounted to/removed from the case, the handle is brought into a second orientation in which the handle is pivoted from a first orientation.
