Anti theft performance of aluminum cover
The anti-theft performance of aluminum covers is mainly achieved through structural design and a one-time opening mechanism, ensuring that the product cannot be restored once opened, playing a role in anti-counterfeiting and anti-theft.
1. Anti theft structure design
The core anti-theft mechanism of aluminum anti-theft bottle caps lies in their unique structural design. Common types include connected bottle caps and burst bottle caps: connected bottle caps have grooves cut on the circumference at a certain height, and the connection point breaks when opened; The burst bottle cap has both circular grooves and vertical cutting marks, and when opened, both the connecting point and the vertical cutting mark break at the same time.
Taking the integrated anti-theft aluminum bottle cap as an example, its typical structure includes the cap body, anti slip threads, sealing gasket, cap screw sleeve, connecting block, anti-theft ring, and anti-theft snap ring. The lower end of the bottle cap is equipped with a connecting block, and the lower end of the connecting block is equipped with an anti-theft ring. The inside of the anti-theft ring is equipped with an anti-theft snap ring, which is locked by fixing the convex ring and cooperating with the bottle mouth. When the bottle cap is first unscrewed, the anti-theft ring separates or breaks from the bottle cap body, forming an irreversible opening mark. This structural design ensures that once opened, it cannot be restored to achieve anti-theft purposes.
2. Anti theft type
According to different structures and functions, aluminum anti-theft bottle caps can be divided into the following types:
·Continuous point bottle cap: A groove is cut on the circumference of a bottle cap at a certain height, and the uncut part is called a continuous point. When opened, the continuous point breaks to achieve anti-counterfeiting.
·Bursting bottle cap: both grooves are cut on the circumference and vertical cutting marks are added to the pre burst ring. When opened, both the connecting point and the vertical cutting mark break at the same time, making the anti-counterfeiting effect more obvious.
·Twist off anti-theft bottle cap: It includes an anti-theft twist off ring that is easy for consumers to identify and operate, ensuring that once opened, it cannot be restored.
3. Enable feature recognition
For the convenience of consumers to identify whether the product has been opened, aluminum anti-theft bottle caps usually have the following characteristics: a crisp "click" sound when first opened; The anti-theft connection bridge cannot be restored after breaking; After resealing, the anti-theft ring or anti-theft ring still remains in a broken state, leaving obvious signs of opening. In addition, some high-end bottle caps also adopt non refillable (NRF) technology, which ensures product integrity through a multi-layer protection function system and prevents illegal refilling.
4. Collaboration between sealing and anti-theft measures
Sealing performance and anti-theft performance are interdependent. The inner upper end of the aluminum cap is equipped with a sealing gasket, which can effectively prevent external dust, bacteria, moisture and other pollutants from entering the inside of the cap, keeping the inside of the bottle clean and safe. At the same time, the breakage or deformation of the anti-theft ring also depends on a good sealing structure, ensuring that the anti-theft function is triggered when it is opened normally and remains intact during transportation and storage.
