Liquid container and apparatus in which liquid container is mountable

An apparatus in which a liquid container comprising a liquid containing chamber with a liquid contained therein is mountable, the liquid containing chamber being formed at least partly of a flexible bag,

• wherein the liquid container comprises:
• a first channel in communication with a first opening which opens into the liquid containing chamber;
• a second channel in communication with a second opening which opens into the liquid containing chamber, the second opening being positioned above the first opening in a direction of gravitational force;
• a supply hole communicating with an opening which opens into the liquid containing chamber to enable the liquid contained in the liquid containing chamber to be supplied to an exterior, the opening being positioned between the first opening and the second opening in the direction of gravitational force;
• a communication path allowing the first channel and the second channel to communicate with each other outside the liquid containing chamber to permit a flow of the liquid;
• a volume varying section capable of varying a volume of an internal space which is in communication with the communication path;
• a valve regulating the flow of the liquid in the communication path to a direction from the first channel toward the second channel;
• and
• a displacement section configured to be displaced depending on a pressure in the communication path between the valve and the second opening;
• and
• the apparatus comprises:
• a connection section configured to be connectable to the supply hole so as to allow introduction of the liquid in the liquid containing chamber;
• and
• a section configured to generate a flow of the liquid in the communication path.
