Plastic flip top cap mould

The existing plastic flip cover with an anti-opening protection structure is generally made of polypropylene to ensure the folding performance of the flip hinge. Limited to polypropylene, it has good toughness and can withstand a certain degree of deformation without being damaged. Therefore, most polypropylene anti-opening protection devices can withstand a certain deformation, and the anti-opening protection function is weak, and some consumers can Open the cover when the anti-opening protection structure is destroyed.

1. There is an annular leak-proof ring on the inner wall of the top of the bottle cap;

2. The lower end of the bottle cap is connected to an anti-theft ring through a tensile rib;

3. At the same time, there are a number of sheet-shaped gyroscopic tension wings evenly distributed on the inner wall of the anti-theft ring

The bottle cap designed in this way has the characteristics of strong sealing, good leakage resistance and anti-theft performance, safe and convenient use, can effectively prevent the liquid in the bottle from being contaminated by bacteria, and can ensure that various beverage packages meet the national health standards.
