[0038] The press bottle head subassembly 3 is used for pressing the end of the tubular container away from the rubber plug inlet when the primary stoppering subassembly 1 and the secondary stoppering subassembly 2 are working, and the press bottle head subassembly 3 comprises a pressing plate 31, and the pressing plate 31 is connected with a press bottle drive assembly 32 for driving the pressing plate 31 to move close to or away from the primary stoppering subassembly 1 and the secondary stoppering subassembly 2.
