Abstract:
This invention relates to a pressing device of a liquid food container, and the pressing device is mounted on the container's cover. The pressing device includes a pressing head which is connected to drive a compression part, so that the compression part can drive a first and second anti-leak valves in pressing and releasing actions. The valve heads of the anti-leak valves are alternatively closed and opened under the pressing and releasing actions. Thus, the liquid in the container can be stored in the liquid storage chamber through a liquid suction port, and then extruded out from a liquid outlet through the liquid conduction port. Therefore, the use of the anti-leak valves can effectively and accurately control the liquid out of the liquid's volume and the internal vacuum state, the liquid is locked in the pressing device without dripping in a vacuum state to achieve leak-proof and anti-splash effect.

Claim (Index 2):
The pressing device of  claim 1 , wherein\n the pressing head is provided with a rod portion penetrating the cover, one end of the rod portion is correspondingly embedded in an outer tube, one end of the outer tube is locked to the cover, the compression part is correspondingly assembled inside the outer tube, a piston of the compression part has an actuating rod, one end of the actuating rod is locked to the pressing head, and the actuation rod is provided with an upper positioning member and a lower positioning member, the main elastic member is sleeved outside the actuating rod and located between the upper and lower positioning members;\n a connecting seat is locked on the other end of the outer tube, the liquid storing chamber is disposed in the connecting seat, the connecting seat has a first opening corresponding to the first fixing seat of the first anti-leak valve, a first passage between the first fixing seat and the first opening communicates with the liquid storing chamber, the liquid suction port is disposed at the other end of the connecting seat opposite to the first opening, the connecting seat has a second opening corresponding to a locking seat, the liquid-conducting port is disposed on the locking seat and correspondingly communicates with the liquid storing chamber, the locking seat is correspondingly assembled with the second fixing seat of the second anti-leak valve and the second valve head corresponds to the liquid-conducting port on the locking seat, a second passage between the second fixing seat and the second opening communicates with the liquid outlet; and \n the liquid outlet is arranged on one side of the cover, a hose is sleeved on an outside of the locking seat, the hose is connected and conducted to the liquid outlet.
