[0002] At present, the anti-theft buckles used in lotion pumps or foam pumps on the market are all designed with an unopenable anti-theft tooth between the screw thread and the bottle, so that the screw thread and the bottle cannot be unscrewed, so that the stored content of the bottle cannot be poured out. However, this structure cannot completely prevent the product from being stolen or tried. There is still a possibility of theft. Moreover, it is difficult to identify after trial or theft, thus bringing inconvenience to the user.

[0003] To this end, a new buckle and foam pump anti-theft device with announcement number "CN208264934U" includes a first buckle body and a second buckle body, one end of the first buckle body is provided with a buckle hole, a stopper is provided inside the buckle hole, the other end of the first buckle body is connected to one end of the second buckle body, one end of the second buckle body is provided with a buckle handle for separating the first buckle body, the other end of the second buckle body is provided with anti-slip teeth, the anti-slip teeth are engaged with the stopper, one side of the stopper is in contact with the anti-slip teeth, and the other side is in gap with the anti-slip teeth. It also has the advantage of easy identification, thus improving the convenience of use.

[0004] However, for the above-mentioned new buckle and foam pump anti-theft device, although when the state of the buckle changes, that is, the first buckle body and the second buckle body are separated, it can be used to determine whether the stored items placed in the bottle are stolen, there are still the following obvious defects during use: when the rotation of the screw thread separates the first buckle body and the second buckle body, it can only be determined that the stored items are stolen, but the screw thread and the bottle will still be separated, causing the problem of the stored items being stolen, thereby failing to achieve the anti-theft effect.
