Anti-forge cap of glass bottle

The utility model relates to an anti-counterfeiting cover for the mouths of glass bottles, comprising a bottle body, an inner core, an outer sleeve and a glass cover body. The inner core is plugged in a bottle mouth, the outer sleeve is sheathed on the exterior of the bottle mouth, the glass cover body is covered on the bottle mouth, and the inner core, the outer sleeve and the glass cover body are fixed by a pin. When the utility model is opened, as long as the upper end of the cover body is broken by a key, a bottle with the utility model can be used. Because the structure of the utility model is special and novel, after the utility model is opened, the integrity of the bottle is broken to achieve the purpose of falsification prevention.
