Core Applications      Suitable for carbonated beverages such as cola, soda, and other carbonated beverages; also suitable for juice and mineral water (depending on actual needs).

Sealing Requirements       Extremely high. Requires long-term resistance to internal carbon dioxide pressure.
Special Design     Safe "degassing before disconnecting": Initially releases some gas upon opening to prevent bottle explosion and splashing.

How it work



1.When a new cap is screwed onto a bottle,  presses the ring downward, forcing it to slide over a raised       locking bead below the bottle's threads.


2. Once it slides over, the barbs inside the anti-tamper ring are trapped by the locking bead, preventing        further upward movement.


3. When you first unscrew the cap, the main sidewall moves upward, but the trapped anti-tamper ring          prevents it from following.


4. This upward force instantly breaks the delicate "bridges" connecting the cap and the anti-tamper ring,      completely separating the cap and the ring, confirming that  the bottle has been opened for the first        time.
