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 1):
A pressing device of a liquid food container, wherein the pressing device is mainly installed on a cover of a container, the pressing device comprising a pressing head, a compression part, a liquid storing chamber, a first anti-leak valve, a second anti-leak valve, and a liquid outlet, wherein\n the pressing head is installed on the cover, wherein the pressing head is a member pressed by a user to move relative to the cover to activate the liquid outlet; the compression part is correspondingly assembled at one end of the pressing head and comprises a piston and a main elastic member, and the compression part can be driven via the pressing head to make the main elastic member show a contraction action and drive the piston to move; the liquid storing chamber is disposed inside the pressing device and is provided with a liquid suction port and a liquid-conducting port on two ends of the liquid storing chamber; the first anti-leak valve is correspondingly mounted on the liquid suction port, wherein the first anti-leak valve comprises a first fixing seat, a movably displaced first valve rod is embedded in the first fixing seat, one end of the first valve rod forms a first valve head, a first elastic member is sleeved on the first valve rod, the first elastic member is located between the first fixing seat and the first valve head, the first valve head can seal the liquid suction port or be separated from the liquid suction port; the second anti-leak valve is correspondingly mounted on the liquid-conducting port, wherein the second anti-leak valve comprises a second fixing seat, a movably displaced second valve rod is embedded in the second fixing seat, one end of the second valve rod forms a second valve head, a second elastic member is sleeved on the second valve rod, the second elastic member is located between the second fixing seat and the second valve head, the second valve head can seal the to liquid-conducting port or be separated from the liquid-conducting por; and the liquid outlet connects the second anti-leak valve and communicates with the liquid-conducting port, and the liquid outlet is used for guiding liquid inside the container to flow out.
