Abstract
A liquid accommodating container having a configuration that allows ink to be substantially used up, does not require an increase in size or a complicated construction, and can be fabricated at lower costs. The container includes an ink chamber for holding ink and having an upper air layer. A second chamber is provided in the upper air layer. A partition divides the second chamber into an ink absorber chamber that accommodates an ink absorber and a sub ink chamber for storing a small amount of ink. A third chamber defines a space between the atmosphere and the ink absorber. An upper portion of the sub ink chamber adjacent to the ink chamber is open so as to provide communication between the upper air layer and the atmosphere through the intermediary of the sub ink chamber and the ink absorber chamber in this order. An atmosphere communicating hole is defined. A print head that discharges ink of the ink chamber is provided at the bottom of the container.
