Abstract
A liquid container and an apparatus in which the liquid container is mountable are provided, the liquid container and the apparatus enabling the presence or absence of remaining liquid to be checked without the need for a power source and even after the liquid container is removed. The pressure in a communication path is maintained while ink in a containing section is not supplied to the exterior. Thus, the displacement state of a detection valve which is displaced depending on the pressure in the communication path can be maintained even after removal of an ink tank.
