Two Factors Affecting the Sealability of Medicinal Bottle Caps

The factors that affect the sealing performance of the medicinal bottle cap mainly include the following two points:

1. Cap diameter: The diameter of the cap should be considered when designing the bottle. If the diameter is too large, there will be a gap between the bottle mouth and the cap, which will affect the tightness of the bottle. If the cap of the small bottle and the mouth of the bottle will not fit well, it will also affect the overall tightness of the package. Only when the mouth of the bottle and the bottle cap reach an interference fit can the tightness of the package be ensured, so it is very important to grasp the diameter of the cap well.

2. The flatness of the bottle mouth: the bottle mouth should be flat without burrs. If the bottle mouth is not flat, the lid and the bottle mouth will not fit well, which will affect the tightness of the package. This is mainly related to the control of the production process. In the production process, strictly follow the process and control the various temperatures to avoid this situation.

The above are the two main factors that affect the sealability of pharmaceutical bottle caps. Sealability is an important indicator for testing the quality of packaging. It is related to the stability of the drug and the health of the patient. Control the diameter of the cap and the flatness of the bottle mouth. It is also a prerequisite to ensure the quality of packaging.
