A flask is provided. According to an embodiment of the present invention, a flask stores liquid, and includes: a sensor unit of sensing whether the flask stores liquid therein or not and sensing the position of an upper surface of the liquid inside the flask when the flask stores liquid; a control unit of receiving sensed data from the sensor unit and calculating the volume of the liquid inside the flask by using the position of the upper surface of the liquid sensed by the sensor unit; a display unit of controlled by the control unit, including a touch panel for sensing a touch input at least a portion thereof, and displaying data on the flask, the display unit displaying a gradation on the flask at a regular interval to allow a volume measurement to be made when the sensing unit senses that liquid is stored in the flask, displaying an indication line on the flask to corresponds to the position of the upper surface of the liquid sensed by the sensor unit, and displaying the amount of the liquid inside the flask which is calculated by the control unit as a numerical value on the flask ; and an electronic valve controlled by the control unit and discharging the liquid inside the flask to the outside of the flask, the electronic valve receiving a discharge amount of liquid from the touch panel and being opened to discharge the amount of liquid that corresponds to the received discharge amount. |
