Liquid container and liquid ejection apparatus

A liquid container comprising:

• a liquid storing unit storing a liquid to be supplied to a liquid ejection head;
• and
• a waste liquid storing unit recovering and storing the liquid passing through the liquid ejection head that is waste liquid,
• the waste liquid storing unit including:
• a waste liquid storing chamber holding the waste liquid;
• and
• a waste liquid passage guiding the waste liquid to the waste liquid storing chamber,
• wherein the waste liquid passage is arranged such that at least a part thereof is positioned above a liquid level of the liquid stored in the liquid storing unit with respect to a direction of gravity in each position when the liquid container is positioned so as to direct in a plurality of directions with respect to the direction of gravity,
• wherein the waste liquid passage includes a valve device therein.
