Description

External anti-counterfeiting device for wine bottle

Technical Field

The utility model relates to the technical field of anti-counterfeiting traceability, in particular to an external anti-counterfeiting device for a wine bottle.

Background

The situation of counterfeit wine in the existing white wine selling market is very serious, the traditional anti-counterfeiting means is that anti-counterfeiting marks are made on bottle caps by manufacturers, the anti-counterfeiting marks are prevented from being imitated by other people, but the anti-counterfeiting means cannot guarantee that the wine is sold as a merchant and flows out from the shop of the merchant, the source of the wine cannot be distinguished when the person suspicion the real and false of the wine exists, the bottle body and the bottle cap of the brand wine are arranged in a marking mode and cannot be changed randomly, and the existing anti-counterfeiting technology comprises the steps of anti-counterfeiting reduction and anti-counterfeiting label authentication. The mode of adding the anti-counterfeiting label is used more, the copying cost of the mode is lower, but the mode is easy to damage, and the aim of protecting the original anti-counterfeiting characteristic cannot be fulfilled. The anti-fake bottle cap comprises a bottle cap upper portion and a bottle cap lower portion, wherein the bottle cap upper portion is provided with a threaded connection structure matched with a bottle opening thread, and a connection part easy to tear is arranged between the bottle cap upper portion and the bottle cap lower portion. When liquid such as wine is canned in the bottle, the lower part of the bottle cap is pressed on the bottle opening through special locking equipment, the upper part of the bottle cap is turned outwards, wine is filled into the bottle through special wine filling equipment, and after the wine filling is finished, the upper part of the bottle cap is turned inwards, and the upper part of the bottle cap is fixed on the bottle opening through threads. When the bottle cap is opened, the upper part of the bottle cap is screwed to force the connecting part of the upper part of the bottle cap and the lower part of the bottle cap to be broken, and the lower part of the bottle cap is still left on the bottle mouth. The anti-fake bottle cap can prevent the bottle body from being recycled, prevent the bottle cap from being recovered and reused, and effectively prevent the actions of manufacturing fake and shoddy products or counterfeit commodities by recycling the old bottle body and the old bottle cap. But the bottle body can not be recycled, which causes great waste of resources, and the method has no technical constraint capacity for counterfeit or counterfeit merchants with the manufacturing capacity of the bottle body and the bottle cap, and the counterfeit and shoddy products can still be manufactured by counterfeiting the bottle body and the bottle cap.

The anti-counterfeiting device for the existing wine bottle is mostly arranged on the bottle cap, and only can be carried out in a mode of pasting an anti-counterfeiting label when a dealer or a store wants to further perform anti-counterfeiting treatment on the sold wine bottle after the wine bottle leaves a factory, but the traditional anti-counterfeiting label is easily damaged, and the imitation cost is low. Therefore, in order to enhance the anti-counterfeiting capability, an anti-counterfeiting device which is externally connected to the outside of the wine bottle and closely linked with the wine bottle needs to be arranged, and the anti-counterfeiting device can effectively mark the source of the wine and can protect the original anti-counterfeiting characteristics.
