Description

TECHNICAL FIELD

[0001] The utility model relates to the application field of commodity theft prevention, and particularly relates to a theft prevention device suitable for thermal cup commodity in a shopping mall. BACKGROUND

[0002] In recent years, due to the popularity of thermal cups, more and more thermal cups suitable for specific scenarios have attracted people's attention and favor. Vehicle-mounted thermal cups are favored by many car owners because of their unique size and the feature of being directly drinkable without opening the cover. However, vehicle-mounted thermal cups are usually directly displayed on the shelves of supermarkets or stores when they are sold, which makes them easy to be stolen by thieves and lost.

[0003] Currently, there are theft prevention devices for thermal cup commodities, which contain frequency elements. According to the structural differences, they can be divided into the following types:

[0004] 1. Containing plastic or metal bands, which can be tightly wrapped around the bottle body of the thermal cup. When the thermal cup is taken out of the store entrance without authorization, the antenna can detect the frequency element and trigger the antenna alarm. However, the plastic or metal bands of the theft prevention tag can easily scratch the surface of the thermal cup commodity.

[0005] 2. Containing a cover, which can be tightly wrapped around the bottle body of the thermal cup using plastic or metal bands and clamping blocks. In addition to the theft prevention function of the frequency element, the cover also prevents thieves from disassembling the cup.
