1. The top inner wall of the general plastic cap is provided with a circular leakproof ring; Also has the ordinary plastic bucket cover is to cooperate with the inner cover, does not need to design the leakproof ring;
2. The lower end of the plastic cap is connected with an anti-theft ring by tensile reinforcement;
3. At the same time, there are several sheet cyclotron wings evenly distributed on the inner wall of the anti-theft ring;
Through this design of plastic barrel cover with a firm seal, leak-proof and anti-theft performance, safe and convenient to use, can effectively prevent the liquid in the container from external pollution, can ensure that all kinds of liquid product packaging in line with national safety standards and other characteristics.
So how to reasonable to control plastic cap sealing performance is the key of the production unit is online or offline testing, for plastic security caps, because to test its seal degree, so want to use positive pressure seal tester, but the market’s positive pressure seal tester are directly into sealed container into the compressed air, so when the container to avoid defective explosion, according to expert estimates, a 2.5 liter coke bottle, if there is an explosion when 1.2 MPa, damaging the equivalent of 100-150 grams of the explosive.

The national standard GB/ t17876-1999 has made specific provisions on the detection of this anti-theft plastic bottle cap, such as the bottle cap opening torque force, thermal stability, drop resistance, leakage and sealing performance. The evaluation of sealing performance, cap opening and torque is an effective way to solve the sealing performance of anti-theft plastic caps. According to the different purposes of the cap, there are different regulations on the measurement methods of the cap without gas and the cap with gas. The anti-theft ring (strip) shall be cut off from the sealing cap (excluding the air cap) and used for sealing with rated torque not less than 1.2nm. The sealing tester  shall be used to test and pressurized to 200kPa. The pressure shall be maintained underwater for 1 minute to observe whether there is air leakage or trip-off. The breathable cover (including the air cover) is pressurized to 690kPa, and the pressure is maintained underwater for 1 minute to observe whether there is air leakage, and then the pressure is increased to 1207kPa, and the pressure is maintained for 1 minute to observe whether the plastic cap is off.
According to the production process: can be divided into injection cover and pressure plastic cap;
The suction machine will be mixed materials into the injection molding machine barrel, in the barrel heating to melt plasticization, injection into the mold cavity, in the mold cavity cooling stereotypes, demoulding, and then through the cutting ring, pad, to complete the production of injection cover.
