Technical field
The present invention relates to carafe, and in particular to on carafe can self-sealing bottle cap.
Background technology
In the prior art, after beverage bottle cap is opened, if do not finished off, lid must be covered, is not covered, it is opened
The opening held can also cause second pollution, in addition, drinking bottle mouth is rough, too greatly, suck also inconvenient, and not have
There is the bottle for closing the lid, if overturned, the liquid in bottle can flow out.
The content of the invention
It is an object of the present invention to be directed to the drawbacks described above of prior art, there is provided a kind of to press off in water suction, do not inhaling
When can self-closed bottle cap.
The technical scheme that the present invention is provided is as follows:There is provided one kind can self-sealing bottle cap, including body of the bottle lid, bottle cap sheet
The centre of body is provided with outlet, is a cannelure on the outside of the bottle cap outlet, and a pressure water inner cap is provided with the outlet,
Pressure water inner cap has a semicircular hemisphere jut, and an elastic outlet valve, elastic water outlet are provided with the inside of the hemisphere jut
Valve has an annular edge fitted with the body of the bottle lid medial surface, and its middle part is an inner cavity, and the centre of inner cavity has
One hemisphere jut fitted with the semicircular hemisphere jut, interval is provided with multiple apopores in the annular edge,
The inner side of the body of the bottle lid is provided with corresponding with the plurality of apopore, and inserts the small boss in the apopore.
It is above-mentioned can be in self-sealing bottle cap, the side of the semicircular hemisphere jut of the pressure water inner cap is interval with many
The individual easily broken hook hooked on the cannelure side.
One layer of film of keeping a public place clean can be also covered with the body of the bottle lid upper surface in self-sealing bottle cap above-mentioned.
Advantages of the present invention is as follows:Bottle cap is screwed on bottle, when water suction is needed, the ball of dynamic pressure water inner cap is pressed downward
Shape is raised, the downward elastic extension of band dynamic elasticity outlet valve downwards of pressure water inner cap, and interval has been provided with multiple apopores and has existed in annular edge
The little projection on bottle cap inner side is left in the presence of elastic force, the water in bottle can be by multiple apopores again by the water outlet of bottle cap
Hole is flowed out, and when pressure water inner cap is unclamped, elastic valve can rebound upwards automatically, and the multiple apopores in its annular edge can be in elastic force
In the presence of be inserted in automatically bottle cap medial surface it is corresponding it is little projection in, so as to seal up, the apopore of bottle cap will not water outlet again.
