Background and risks of oral liquids

As a pharmaceutical preparation with good taste, oral liquids are extracted from Chinese herbal decoctions, and additives such as flavoring agents and antibacterial agents are added, and are sealed in bottles in a sterile or semi-sterile form. However, because of its taste close to that of beverages, it is easy for children to mistake it for ordinary drinks, and there is a risk of accidental ingestion. The physiological characteristics of children determine that they have low tolerance for drugs, and excessive consumption may bring serious consequences and even endanger life.

Design of water-based screw caps

In order to reduce the risk of accidental ingestion of oral liquids, water-based screw caps with child protection function are often used. This cap adopts an inner and outer double-layer structure design, and the inner and outer caps are connected by a card slot. When opening the cap, it is necessary to press down the outer cap and rotate it at the same time to drive the inner cap to rotate together and complete the opening action. This design can effectively prevent children from opening the package at will in a short time, reducing the risk of accidental ingestion.

Differences between glass bottles and plastic bottles

Although the water-based screw-on caps are used in both glass bottles and plastic bottles, there are certain differences in their internal designs. It is mainly reflected in the gasket inside the cap. The gasket of the glass bottle cap is relatively thicker, while that of the plastic bottle is relatively thinner. This difference is mainly determined by the different materials of the bottles. Glass bottles are relatively more brittle, and the increase in the thickness of the gasket can enhance its performance in sealing and pressure resistance, ensuring that the liquid is not easy to leak. Since the material of plastic bottles is relatively soft, the gasket of the cap can be relatively thin, which can ensure the sealing and reduce the production cost at the same time.

The design difference between the oral liquid bottle caps in glass bottles and plastic bottles is mainly reflected in the thickness of the gasket, which is determined according to the material of the bottle body and aims to ensure the good sealing of the bottle. Through reasonable design and selection, the water-based screw-on cap can effectively reduce the risk of accidental ingestion of oral liquid and ensure the safety of children's medication.

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.

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.
