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 the pressing head is assembled on a hollow tube, one end of the hollow tube penetrates the cover and is correspondingly embedded inside an outer tube, one end of the outer tube is locked to the cover, the outer tube forms a liquid storing chamber, the end of the hollow tube in the outer tube corresponds to a piston that locks the compression part, the liquid-conducting port is disposed at a bottom of the piston, the second anti-leak valve is installed inside the piston, and the second fixing seat is correspondingly arranged on an opening of the piston, a base is correspondingly disposed at a bottom of the outer tube, the liquid suction port is disposed on a bottom of the base and communicates with an inside of the container, the first anti-leak valve is installed inside the base, the first fixing seat is correspondingly arranged on an opening of the base, the main elastic member of the compression part is correspondingly installed in the liquid storing chamber of the outer tube, the upper and lower positioning members are separately arranged on both ends of the main elastic member, the upper positioning member is located under the piston and is provided with an upper perforation corresponding to the liquid-conducting port, the lower positioning member is located above the base and has a lower perforation corresponding to the liquid suction port, and the liquid outlet is disposed on the hollow tube and communicates with the liquid-conducting port.
