As an important part of plastic bottles, medicinal bottle caps also incorporate the anti-theft function while ensuring the overall tightness of the packaging.
The anti-theft function of the bottle cap is actually derived from the beverage bottle, mainly to remind the buyer whether the beverage has been opened by other people before drinking, and play a vigilant role. In recent years, the design of some medicinal bottle caps has borrowed from this method and applied this function to medicine packaging.

The principle of anti-theft of medicinal bottle caps is to use a small circle under the bottle cap, also called a one-time breaking anti-theft ring. Unscrewing the cap, the anti-theft ring will naturally fall off and stay on the bottle. We can judge whether the medicine is based on the state of the anti-theft ring. The sealed one has been opened maliciously. It is generally impossible to tell from the appearance of the bottle whether the bottle has been opened, and the design of the anti-theft ring solves this problem well. Bottle caps are generally made of polypropylene raw materials through injection molding process. After injection molding, they are rotated on the machine, and a knife is used to cut the anti-theft ring with multiple points connected to the bottle cap at 3 mm from the edge of the bottle cap, and put it into the cap to dry After filling and sealing, a complete bottle cap is produced.
Of course, with the continuous improvement of various processing techniques, the functions of medicinal bottle caps are still being upgraded, such as moisture-proof caps with desiccant on the caps, press-screw caps that can prevent children from opening at will. These special functions are also Make the importance of packaging more prominent.
