Novel false proof bottle cap

Abstract

The invention relates to a winebottle cover with anti-counterfeiting function. The anti-counterfeiting winebottle cover includes an external cover, a valve and a fixing ring; the small valve is arranged on the upper part of the bottle mouth; the bottle cover also includes a propping nut, a connecting seat and a rotation-stop screw; the connecting seat is fixed to the external edge of the bottom mouth by the fixing ring; the internal side of the bottle mouth is provided with a rotation-stop reinforcement; the internal and external sides of the small valve also are respectively provided with a rotation-stop reinforcement; the external rotation-stop reinforcement of the small valve is buckled with the rotation-stop reinforcement at the internal side of the connecting seat; the longitudinal sections of the rotation-stop screw and the propping nut are the convex-shaped without bottom parts; the rotation-stop screw is arranged in the interior of the small valve; the propping nut is arranged on the upper part of the rotation-stop screw; the rotation-stop screw and the propping nut are connected by the screw thread; the external edge of the rotation-stop screw is provided with a rotation-stop vane which is buckled with the internal rotation-stop reinforcement of the small valve; the internal side of the external edge of the external cover is connected with the external edge screw thread of the connecting seat; the lead between the propping nut and the rotation-stop screw is more than the lead between the internal side of the external edge of the external cover and the external edge of the connecting seat; the internal side of the external cover is connected with a propping hexagonal nut; the external cover corresponding to the upper head of the propping nut is covered with a concave trough beneficial for bursting.

Description

technical field [0001] The invention relates to a wine bottle cap, in particular to a wine bottle cap with an anti-counterfeit function. Background technique [0002] At present, there are many kinds of anti-counterfeiting wine bottle caps commonly seen on the market, among which, the more common one is that the bottle cap includes an upper cap, a lower cap and a bursting ring, and there are multiple notches for connecting points to be broken distributed on the circumference of the bursting ring , there are multiple tooth caps on the upper and lower end faces. When the bottle cap is tightened, the upper tooth cap is buckled in the square groove of the tooth ring at the mouth end of the upper cap, and the lower tooth cap is snapped into the tooth plate between the burst ring and the lower cap. In this way, when the upper cap is rotated When capping, the bursting ring will be broken along the connection point to be broken, and cannot be restored. In this way, the anti-counter...

AI Technical Summary

Problems solved by technology

When the bottle cap is tightened, the upper tooth cap is buckled in the square groove of the gear ring at the mouth end of the upper cap, and the lower tooth cap is snapped into the tooth plate between the burst ring and the lower cap. In this way, when the upper cap is rotated When capping, the burst ring will be broken along the connection point to be broken and cannot be restored. This method is used to achieve the purpose of anti-counterfeiting. After the burst ring is damaged, the overall damage is more obvious, which affects the overall appearance of the bottle cap.
