The sealing performance of the anti-theft caps of chemical plastic barrels is the main factor affecting the leakage of packaging and product deterioration. Through reasonable control of the sealing performance, it can ensure its good opening performance and avoid the occurrence of leakage. The above is a brief introduction to leak detection and sealing performance testing of anti-theft caps for chemical plastic drums, hoping to help the quality control of the production and use units of anti-theft caps for chemical plastic drums.
The utility model relates to an anti-theft bottle cap, especially an improvement of the anti-theft bottle cap through the anti-theft ring. The anti-theft bottle cap includes a cover body and an anti-theft ring. The cover body and the anti-theft ring are integrated by a number of frangible connection bridges. The inner wall of the anti-theft ring is provided with a plurality of equally divided circumferential inverted teeth, which are inclined Upwards, a space is provided between the inner wall of the anti-theft ring and the inside of the inverted tooth. The utility model has simple and reasonable structure, delicate parts, simple assembly, easy manufacture, low cost, not easy to damage, and good sealing and anti-theft effect.
Equipped with a special chemical plastic barrel anti-theft cap sealing performance test device, the chemical plastic barrel anti-theft cap is sealed with a special connection unit link, placed in a transparent observation tank, set the test pressure or leakage and other test conditions to start the test, The instrument automatically performs the test, and test data such as test pressure and leakage can be displayed directly on the LCD screen. At the same time, it can also be judged by transparently observing the bubble condition in the tank.https://www.fhpails.com/
