PURPOSE: A container vacuumizing system is provided to easily vacuumize a container by integrating a vacuumizing device with the container and by properly composing a chamber air moving passage, an air intake pipe and an air moving passage. CONSTITUTION: A FA shaped container vacuumizing device consists of a suction chamber(2), an upper chamber(3) and a lower chamber(1). A check valve contains a container suction valve(6), a suction valve(7), a vertical valve(9) and a lower valve(11). In the structure, air is sucked to the suction chamber and flows to the upper chamber from the suction valve by pushing a push portion. Then, the air in the upper camber flows to the lower chamber and finally flows outside. Thus, the air complicatedly flows by a vertical piston movement.
