Abstract
A liquid container which supplies ink to its exterior until the ink is almost depleted and allows simple detection of the remaining ink amount, is constructed to distribute components of the ink even after a prolonged standing. The liquid container is provided with a connecting portion for connection to an ink deriving tube and an air introduction tube of an ink jet printer. Both the ink deriving tube and the air introduction tube are positioned for connection to the connecting portion at a position deviated from a center of the bottom of the liquid container. The deviation facilitates mixing of ink components as ink is supplied from the container.
