It features a self-sealing silicone valve that opens under pressure and closes instantly when released, ensuring:

Smooth and controlled syrup dispensing

No dripping or stringing

Leak-proof sealing during storage and transport

Compared with traditional flip-top caps, this syrup bottle cap delivers a cleaner, more hygienic, and user-friendly experience.
