TECHNICAL FIELD

[0001] The utility model relates to a bottle cap technical field, concretely relates to a turnover bottle cap structure. BACKGROUND

[0002] Generally, the bottle body made of soft harmless resin to human body is generally used for containing food, cosmetics or medicine. When using, the liquid or gel product in the bottle body is squeezed out from the discharge hole of the bottle cap by squeezing the bottle body. However, there is a problem that when the bottle cap is not closed due to accident (for example, forgetting to close), the external air is easy to enter the bottle body through the discharge hole, so that the product in the bottle body is easy to deteriorate.

[0003] To this end, a small pump body structure (airless pump bottle) is installed in the bottle body to realize the quantitative discharge of the liquid or gel product in the bottle body, so as to prevent the external air from entering the bottle body. When using, the button of the pump body is pressed, the liquid or gel product stored in the bottle body is pumped out, then when the pressure is removed, the button is driven to move upward by the elastic member such as spring, and as the pressure of the gap part between the button and the bottle mouth gradually decreases, the liquid or gel product in the bottle body is partially lifted to the gap part between the button and the bottle mouth, so that the product adhered to the outer wall of the button and the inner wall of the bottle mouth is not completely discharged by the pump body structure, so there is a problem of waste of liquid or gel product.
