The cap of the effervescent tablet bottle not only plays a sealing role, but also has the functions of moisture-proof and anti-theft. It consists of four parts: desiccant, cardboard, coil spring and anti-theft ring.
Desiccant: The moisture-proof function of the cap of the effervescent tablet bottle is mainly reflected in the small medicine compartment on the top of the cap, which contains silica gel and molecular sieve to prevent moisture. The moisture content, saturated moisture absorption rate and short-term moisture absorption rate of the desiccant must meet the national requirements in order to play a better role.
Cardboard: used to isolate desiccants and drugs and avoid direct contact. Generally, the moisture content of cardboard is required to be less than 6%, no fluorescent reaction is allowed, and the heavy metal is less than 5ppm. The quantitative ratio is 210-400g/㎡. The thickness is 0.46-0.55mm pure high-quality wood pulp white cardboard.
Coil Spring: This is a unique design of effervescent packaging. It is made of soft LDPE raw material, which is used to compress the tablet and prevent the drug from breaking due to various external forces.
Anti-theft ring: Its design is derived from the beverage bottle, which is connected with the lid. After opening, the anti-theft ring automatically falls off. It is mainly used to remind consumers whether the drug has been maliciously opened, and plays a vigilant role.
The cap of the effervescent tablet bottle is mainly composed of the above four parts, each part is designed with its special function, they together constitute a complete cap to protect the safety and stability of the drug.
