Standard for testing oral liquid bottle caps


In the testing standard of aluminum cover, there are clear requirements for the sealing performance testing of aluminum cover. According to the different uses of aluminum cover, there are different regulations on measuring methods of non-gas cover and gas cover.

In the testing standard of aluminum cover, there are clear requirements for the sealing performance testing of aluminum cover. According to the different uses of aluminum cover, there are different regulations on measuring methods of non-gas cover and gas cover. It is necessary to cut off the anti-theft ring of the oral liquid bottle cap and seal it with rated torque of no less than 1.2NM. Test it with a sealing tester, pressurize it to 200kPa, keep the pressure underwater for 1 minute, and observe whether there is gas leakage or trip. Keep the pressure under water for 1 minute to observe whether there is gas leakage. Then increase the pressure to 1207kPa and keep the pressure for 1 minute to observe whether the aluminum cover is trip.
However, in the reasonable control of the oral liquid bottle cap easy to open at the same time must pay attention to the detection of closely related sealing performance, otherwise it will be due to the lack of torque force caused by leakage of hidden dangers. It can be seen that the sealing performance of aluminum cover is also a key detection index to achieve convenient consumption of containers.
Relationship between torque force of oral liquid bottle cap and sealing performance of aluminum cap
In the national standard, we can see that the sealing performance test of aluminum cover is carried out under a certain torque force of aluminum cover. Here we briefly discuss the relationship between the torque force of oral liquid bottle cap and the sealing performance of aluminum cap. The torque force of the aluminum cover is the main factor affecting its sealing performance. Too much torque force will bring great difficulties to the opening and locking of the aluminum cover, reducing the convenience of use, and too small torque force will reduce the sealing performance of the container, which may lead to the leakage of the product in transit. Nowadays, packaging design should provide more convenience for realizing rapid consumption, and the easy opening of oral liquid bottle cap is one of the goals to be achieved.
Acceptable sealing performance of oral liquid bottle cap:
The sealing performance of the aluminum cap is not only an important index to evaluate whether the oral liquid bottle cap is qualified or not, but also through testing this index can not only scientifically evaluate the sealing performance of the container, but also can reasonably control the opening force of the oral liquid bottle cap on the premise of ensuring the safety of the package to avoid the inconvenience caused by excessive control of the sealing performance.
