Abstract
A method and an apparatus for extruding a highly viscous fluid from a tank. A pressing member having an air flow path is disposed in the tank containing the highly viscous fluid and having a discharge outlet for discharging the highly viscous fluid. Air in the tank which is present between the pressing member and the highly viscous fluid is removed through the air flow path of the pressing member by moving the pressing member into the tank until the pressing member contacts the highly viscous fluid. The highly viscous fluid is then extruded from the outlet of the tank by pressing the pressing member against the highly viscous fluid. Thereafter, air is introduced through the air flow path of the pressing member into a region of the tank between the pressing member and the discharge outlet of the tank, and the air is then pressurized and ejected through the discharge outlet of the tank.
