Tank and liquid consuming apparatus including the same

A tank for storing liquid to be supplied to a liquid consuming device, comprising:

• a liquid inlet port;
• an atmosphere open port;
• a liquid outflow port;
• a first liquid chamber configured to store the liquid to be supplied to the liquid consuming device, the first liquid chamber including a first atmosphere communication channel in communication with the atmosphere open port to open an inner space of the first liquid chamber to the atmosphere;
• a second liquid chamber configured to store the liquid to be supplied to the liquid consuming device, the second liquid chamber being in communication with the first liquid chamber, and including a second atmosphere communication channel in communication with the atmosphere open port to open an inner space of the second liquid chamber to the atmosphere;
• and
• a liquid channel provided for at least one of the first liquid chamber and the second liquid chamber, the liquid channel including a liquid inflow port and a liquid outflow port, wherein the liquid stored in the first and second liquid chambers flows into the liquid channel via the liquid inflow port and the liquid flowed into the liquid channel flows out toward the liquid consuming device via the liquid outflow port,
• wherein the liquid inside the liquid channel is movable along with a liquid consumption of the liquid consuming device;
• and
• wherein in a case that the tank is in a usage posture, and that the liquid is stored in the first liquid chamber and the second liquid chamber, a liquid level of the liquid stored in the first liquid chamber is formed independently from a liquid level of the liquid stored in the second liquid chamber.
