Package bottle cable of converting ventilation direction of one-way ventilation valve

Abstract

The invention discloses a package bottle capable of converting a ventilation direction of a one-way ventilation valve. The package bottle comprises a bottle body and a bottle cap and also comprises around waterproof and dustproof ventilation film, a cylindrical exhaust pipe, a cylindrical supporting plate, a dustproof cover and a ball valve, wherein the round waterproof and dustproof ventilationfilm is glued and fixed on an annular boss located at the center of the bottom end inside the bottle cap; a round through hole 3 used for installation of a rotation shaft of the ball valve is formed radially in the center of the right end of the cylindrical exhaust pipe; the ball valve comprises the rotation shaft, an elastic rubber ball body, the one-way ventilation valve and a handle; the one-way ventilation valve is glued and fixed in a round through hole 2 located at the top end of the elastic rubber ball body; the cylindrical supporting plate is disposed on the peripheral ring of the inner wall of the lower end of the cylindrical exhaust pipe; and the upper end of the cylindrical exhaust pipe can be connected by screws with a suction pipe of an adapted small vacuum pump. The package bottle disclosed by the invention has the beneficial effects that, after installation of the one-way ventilation valve on the bottle cap, air in the bottle body can be discharged outwards in one direction by the small vacuum pump, and the problem that the bottle cap cannot be opened easily can be solved through conversion of the ventilation direction of the one-way ventilation valve.

Description

technical field [0001] The invention relates to the technical field of packaging bottles, in particular to a packaging bottle capable of switching the ventilation direction of a one-way ventilation valve. Background technique [0002] At present, the one-way ventilation valve is widely used in packaging bags. The air in the bag is discharged in one direction through a small vacuum pump to form a vacuum in the bag, which is beneficial to reduce the volume of textiles such as quilts and clothing in the bag. For storage and carrying. Since the material of the vacuumized packaging bag is soft plastic, even though the bag body is in a negative pressure state, when opening, you only need to pull the zipper to open the bag mouth. [0003] The one-way ventilation valve is also applied to the packaging bottle. The application status is: by installing the one-way ventilation valve on the bottle cap of the packaging bottle, the gas generated in the storage process of the fermented bea...
