Tightness Testing Of Medicinal Bottle Caps

The function of medicinal bottle caps is mainly reflected in the sealing and aesthetics. The sealing is the basic function of the cap and must be guaranteed by the manufacturer. In order to ensure the quality of the lid, it is particularly important to test it for leaks.

The sealing performance of medicinal bottle caps is not only an important indicator for evaluating the qualification of bottle caps, but also by testing this indicator can not only scientifically evaluate the sealing performance of the container, but also reasonably control the bottle under the premise of ensuring packaging safety. The opening force of the lid avoids the inconvenience of use due to excessive control of the sealing performance. In the detection, the bottle cap seal detector is generally used. The detection steps are as follows:

1. Partially cut off the sealing part, and pay attention to cutting according to the required standards.

2. Clamp the cut out part with the chuck of the instrument, and fix it with the kiln. In order to avoid irregular movement in the process of pressurization. The bottle cap sealing performance test device is filled with clean water and overflows the sample holder at a height. Then close the cover and secure.

3. Turn on the air source and adjust the pressure to the pressure required by the container to be tested according to the relevant standards. The cap was then kept under pressure for 1 minute under pressure.

4. Observe the test results. Check for air bubbles in the water or water in the bottle while maintaining pressure to interpret the leak of the cap.

It is very important to test the tightness of medicinal bottle caps. In addition, if it is a cap with a moisture-proof function, it should also ensure that the desiccant is well sealed.
