Description

Technical Field

[0001] The present invention relates to an anti-theft cap. Background Art

[0002] Some containers need to be equipped with anti-theft caps to determine whether the container has been opened through the state of the anti-theft cap.

[0003] Generally, an anti-theft cap is provided with an anti-theft structure that will be damaged when opened. Therefore, it can be judged whether the container has been opened by visually observing whether the anti-theft structure of the anti-theft cap is damaged.

[0004] However, the anti-theft structures of existing anti-theft caps are often relatively complex, which not only increases the production cost of the anti-theft caps, but also makes it unclear and intuitive enough to check whether the anti-theft structure is damaged, and is not convenient for identification.

[0005] In addition, existing anti-theft caps generally can only be used to identify and judge whether the container has been opened, and the functions are relatively single. They cannot assist in judging whether the storage environment of the container exceeds the standard, such as whether the temperature and humidity of the container storage environment exceed the standard. Therefore, existing anti-theft caps need to be further improved. Summary of the Invention

[0006] To solve the defects of the prior art, the present invention provides an anti-theft cap, including: a lower cap fixedly connected to the container, an upper cap threadedly connected to the lower cap, and an anti-theft buckle respectively connected to the lower cap and the upper cap; The anti-theft buckle includes: a male buckle fixedly arranged on the lower cap, and a female buckle fixedly arranged on the upper cap and buckled with the male buckle; The male buckle includes: a column located below the upper cap and having one end fixedly connected to the outer side wall of the lower cap, and a buckle head fixedly arranged at the outer end of the column; The female buckle includes: a buckle ring sleeved on the column and located inside the buckle head, and a connecting strip fixedly connecting the outer ring of the buckle ring to the upper cap; The buckle head can lock the buckle ring on the column; the connecting strip can be disconnected during the unlocking process of the upper cap and the lower cap.
