LIQUID DISCHARGE CONTAINER

PROBLEM TO BE SOLVED: To provide a liquid discharge container allowing exact confirmation of liquid amount in the container. SOLUTION: In this liquid discharge container having the container 3 for storing liquid, an electric pump 5 (a discharge means) for discharging the liquid in the container 3, a pressure sensor 8 (a liquid level detection means) for outputting a signal corresponding to the liquid amount of the liquid in the container 3 and a control circuit 9 (a control means) for determining the liquid amount based on the signal of the pressure sensor 8, the control circuit 9 determines a difference of the present value and an initial set value of the liquid amount detected by the pressure sensor 8 at the time of a prescribed condition and increases/decreases the difference to/from the liquid amount detected by the pressure sensor 8.
