Differences between 28mm oral liquid covers in solid and liquid dosage forms

As an important part of drug packaging, the medicinal bottle cap plays a very critical role in the overall sealing of the packaging. The 28mm oral liquid cap is a special cap with child protection function, which is mainly used to prevent children from accidentally opening the package and ingesting drugs. It is widely used in various solid and liquid preparations packaging, and its design also has certain differences in different applications.

28mm child resistant cap for liquid

Application of 28mm oral liquid cap in solid preparation packaging:

Solid drugs such as tablets and capsules have relatively high requirements for moisture resistance. In addition to requiring good sealing of the packaging to isolate the invasion of external water vapor, the drug itself also carries a certain amount of water molecules during the preparation process, so internal moisture resistance is equally important. The 28mm cap has a small medicine compartment on the top of the cap, which is used to store desiccant, so that it can absorb internal moisture, maintain environmental stability, and ensure that the drug will not be damp and deteriorate.

Application of 28mm oral liquid cap in liquid preparation packaging:

Liquid preparations such as oral liquids, suspensions, syrups, etc., are very easy to cause leakage problems due to violent shaking during transportation, so the sealing performance of the packaging is more important. In order to achieve better sealing, it will do more research on the selection of gaskets to make the lid and gasket fit more closely.

The above is the differentiated design of the 28mm oral liquid cover in solid and liquid preparation packaging. Although the design is slightly different, it focuses on child protection in terms of function. Through the design of the inner and outer double-layer structure, it increases the difficulty of opening the lid to prevent children from accidentally ingesting medicines, thus protecting children's safety.
