Abstract
The utility model discloses a seal beverage bottle cap which can eliminate negative pressure, which comprises a seal lid and a nozzle; an air back hole is positioned on the side of the nozzle in the seal lid; a rubber chip is fixedly connected with the air back hole; an incision exists in the rubber-chip; the rubber-elastic tension of the utility model can bear the weight of the liquid in the bottle to prevent leakage; when a vacuum exists in the bottle, the atmospheric pressure out of the bottle overcomes the rubber-elastic tension, makes rubber incision opening; air gets into the bottle and eliminates the vacuum of the bottle; the liquid can be sucked out continuously and smoothly. The utility model has the advantages of simple structure, convenient and practical usage.
Description
Affiliated technical field
The utility model relates to a kind of sealing drink bottle cap.
Background technology
When the sealing drink bottle of general band suction nozzle is opened the sealing position with mouth imbibition body, along with the minimizing of liquid, the air in the bottle forms negative pressure and imbitition continuously, and some product is in order to eliminate negative pressure, on seal bottle cap, open a little return-air hole, but unavoidably can produce leak of liquid.
The utility model content
The purpose of this utility model is to provide a kind of sealing drink bottle cap of eliminating negative pressure function that has.
A kind of sealing drink bottle cap of eliminating negative pressure that the utility model provides comprises seal cover cap and suction nozzle, and the side that is positioned at suction nozzle on the seal cover cap has a return-air hole, is fixed with a sheet rubber in the return-air hole, has an otch on the sheet rubber.
Communicate in return-air hole of the present utility model and the bottle, fix the sheet rubber of a suitable thickness in the return-air hole, have an otch on sheet rubber, otch can be in-line or other shape.The sheet rubber elasticity tension can bear the weight of liquid in the bottle, prevents to leak; When producing negative pressure in the bottle, the outer bar pressure of bottle overcomes the elasticity tension of sheet rubber, and the in-line of sheet rubber or the otch of other shape are opened, and in the air admission bottle and eliminate negative pressure, liquid can be sucked out smoothly continuously.
Compare with the sealing drink bottle cap of existing band suction nozzle, the utility model both can be eliminated negative pressure, can prevent from again to leak, and was simple in structure, convenient and practical.
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
