Problems solved by technology

When you use it next time, the liquid will stick to your hands, which is very unhygienic and wastes the liquid at the same time
At present, I have only seen the structure with a collection tank at the mouth of the bottle, which only solves the problem that the liquid does not pollute the bottle body, but it has no recycling function. When it is used next time, a small amount of liquid will still flow out of the collection tank.

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but does not constitute any limitation to the present invention. figure 1 and figure 2 As shown, the present invention includes a bottle cap 1, the bottom of the bottle cap 1 has an internal thread, the upper part of the bottle cap 1 is provided with a groove, the groove is provided with a return hole, and the middle of the return hole is provided with a shaft hole , the shaft hole is equipped with a piston valve. image 3 As shown, the piston valve is composed of an upper body 2 located in the groove and a piston body 3 located at the bottom of the bottle cap 1. The piston rod on the upper part of the piston body 3 passes through the shaft hole upwards and is snapped together with the upper body 2 as a whole. . The diameter of the upper body 2 is smaller than the outer diameter of the backflow hole, and the diameter of the lower part of the ...

Abstract

The invention discloses a bottle nozzle capable of recovering overflowed liquid. The bottle nozzle comprises a bottle cover, an inner thread is arranged on the lower part of the bottom cover, a grooveis formed in the upper part of the bottom cover, a backflow hole is formed in the groove, a shaft hole is formed in the middle of the backflow hole, and a piston valve is mounted in the shaft hole. In a normal state, the piston valve falls through gravity, an upper body falls into the groove, and the liquid, concentrated in the groove, outside a bottle flows back into the bottle from the backflowhole. When the liquid is poured, the bottle inclines, due to the pressure difference inside and outside the bottle, the liquid in the bottle pushes the piston valve forwards until the backflow hole is blocked by a piston body, and thus the liquid in the bottle does not flow out from the backflow hole.

Description

technical field [0001] The invention relates to a container, in particular to a bottle mouth capable of recovering overflowing liquid. Background technique [0002] Bottled liquids can be seen everywhere and are widely used. During use, after the liquid is stopped pouring out, there will be liquid flowing down the outer wall of the bottle. When you use it next time, the liquid will stick to your hands, which is very unhygienic and wastes the liquid at the same time. At present, I have only seen the structure with a collection tank at the mouth of the bottle, which only solves the problem that the liquid does not pollute the bottle body, but it has no recycling function. When it is used next time, a small amount of liquid will still flow out of the collection tank. Contents of the invention [0003] The object of the present invention is to provide a bottle nozzle capable of recovering overflowing liquid. [0004] The technical solution of the present invention is: compri...
