Liquid container and apparatus in which liquid container is mountable
A liquid container enables a liquid contained in a liquid containing chamber to be supplied to an exterior through a supply port. The liquid container includes a first channel, a second channel, and a communication path. The first channel is in communication with a first opening which opens into the liquid containing chamber. The second channel is in communication with a second opening which opens into the liquid containing chamber, the second opening being positioned above the first opening in a direction of gravitational force. The communication path allows the first channel and the second channel to communicate with each other outside the liquid containing chamber to permit a flow of the liquid.
