Effervescent tube spring caps and non-spring caps

Mar 05 , 2024

The design and function of the effervescent tube cap are crucial to ensuring drug quality and safety. It has a moisture-proof function, which is mainly achieved by storing silica gel and molecular sieves. Effervescent tubes are mainly used for VC effervescent tablets, capsules and other drugs that require high moisture-proof properties. Depending on the medicine contained, you can choose a cap with spring  or a non-spring cap as the type of cap. This article will focus on the two different cap types for this packaging: spring caps and non-spring caps, and explore the differences between them.

First of all, what these two types of caps have in common is that they both have a moisture-proof function, which is mainly achieved by storing silica gel and molecular sieves.

The spring cap is a cap with a spiral-shaped soft spring. Its unique design can hold the tablets in place and prevent them from breaking due to external force during transportation. This spring structure effectively reduces transportation risks and ensures the safety and integrity of the medicine.

Non-spring caps have no springs on the bottle caps. Non-spring caps are usually suitable for chewable vitamin tablets, small-format candy tablets, capsule drugs and other drugs that have high moisture-proof requirements. Give the effervescent tube more space to use.
