Abstract
A liquid container includes a negative pressure producing member accommodating chamber accommodating a negative pressure producing member for absorbing and retaining the liquid, and a liquid containing chamber for containing the liquid. The liquid containing chamber is in fluid communication with the negative pressure producing member accommodating chamber through a communicating portion, and is substantially sealed except for the communicating portion. A partition wall partitions the liquid container into the negative pressure producing member accommodating chamber and the liquid containing chamber except for the communicating portion. The negative pressure producing member is provided with a recess at a position corresponding to the communicating portion, wherein the recess forms a space and a ceiling portion of the space provided functions as a gas introduction surface which is substantially horizontal when the liquid container is in an in-use orientation.
