Claims

[Scope of utility model registration request]

It has a discharge pipe and a suction pipe which are branched from the main pipe and are vertical, and the discharge pipe is connected to the branch part at the lower part, and a discharge valve seat and a discharge valve body are provided at the upper part, and the discharge valve dust is The suction pipe is open to the outside air, and the upper part of the suction pipe is connected to a branch part, and the lower part thereof is provided with a suction valve body and a suction valve seat.The suction valve seat is open to the outside air, and When the inside of the container becomes pressurized, the suction valve body and the suction valve seat come into close contact with each other, and the discharge valve body and the discharge valve seat separate, allowing the contents inside the container to be discharged to the outside of the container, creating a negative pressure inside the container. When this happens, the discharge valve body and discharge valve seat come into close contact with each other, and the suction valve body and suction valve seat separate, allowing outside air to flow into the container.
