Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting label technology, specifically to a multi-key verification anti-counterfeiting label. Background Art

[0002] Counterfeit and substandard products severely disrupt the market economy, causing losses to consumers and legitimate manufacturers. To protect their goods from counterfeit products, businesses, and the government, to protect currency, securities, and identity documents from counterfeiting, have developed various anti-counterfeiting and encryption methods. Among these, anti-counterfeiting labels affixed to product surfaces are one of the most important methods. However, existing anti-counterfeiting labels have flawed designs. Their anti-counterfeiting information is generally obtained by mass-producing a specific template. While simple and inexpensive to produce, the information is limited, easily counterfeited, and ineffective. Furthermore, the identification methods are complex, and even with third-party tools or platforms, the efficiency is low, and the labels are inconvenient for consumers. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-key verification anti-counterfeiting label with reasonable structural design, good anti-counterfeiting effect, simple identification, convenient use and good practicality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-key verification anti-counterfeiting label, comprising a label body, a key verification part integrally provided at the front end of the label body, a key slot provided on the upper surface of the key verification part, an anti-counterfeiting key provided in the key slot, a first positioning groove provided on a partial position of the upper surface of the anti-counterfeiting key, an anti-counterfeiting graphic laser engraving layer provided in the first positioning groove, and a scratch-off silver ink cover layer provided on a partial position of the anti-counterfeiting graphic laser engraving layer;

[0005] A fragile paper layer is provided between the front end face of the anti-counterfeiting key and the front inner wall of the key slot; a temperature-sensitive color-changing filler layer is provided between the rear end face of the anti-counterfeiting key and the rear inner wall of the key slot.

[0006] A positioning iron piece is fixedly adhered to the lower end surface of the anti-counterfeiting key, and an anti-counterfeiting verification code imprint layer is provided on the lower end surface of the positioning iron piece.

[0007] The lower end face of the anti-counterfeiting key has a fluorescent graphic anti-counterfeiting coating in a certain area.

[0008] The present invention is further configured such that: the label body is provided with a transparent protective surface layer, a coloring layer, an anti-counterfeiting pattern layer, a positioning base layer and a wear-resistant bottom layer from top to bottom; a second positioning groove is provided at a local position on the upper surface of the positioning base layer; and a passive electronic anti-counterfeiting label is embedded in the second positioning groove.

[0009] The present invention is further configured such that: the passive electronic anti-counterfeiting label is an RFID passive electronic anti-counterfeiting label or an NFC passive electronic anti-counterfeiting label, and the upper surface of the passive electronic anti-counterfeiting label is flush with the upper surface of the positioning base layer; the transparent protective layer, the coloring layer, the anti-counterfeiting pattern layer, the positioning base layer, the wear-resistant bottom layer and the passive electronic anti-counterfeiting label are bonded together to form an integrated structure.

[0010] The present invention is further configured such that: the anti-counterfeiting pattern layer includes a holographic anti-counterfeiting pattern part and a QR code part, and the anti-counterfeiting pattern layer is made of photosensitive resin material or nylon material, and the thickness of the anti-counterfeiting pattern layer is 5-150μm.

[0011] The present invention is further configured such that the upper surfaces of the fragile paper layer and the thermochromic filler layer are flush with the upper surface of the key verification part.

[0012] The present invention is further configured such that: a number of magnetic pieces are fixedly provided at the bottom of the key slot; the anti-counterfeiting key is made of plastic, and a tear-off protrusion is integrally provided on the right end of the anti-counterfeiting key.

[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has a reasonable structural design. Users can first identify authenticity through the holographic anti-counterfeiting pattern and QR code on the anti-counterfeiting pattern layer. Then, they can manually scratch off the scratch-off silver ink covering layer to see the complete anti-counterfeiting laser engraving layer. Next, they can pull the anti-counterfeiting key out of the key slot by tearing off the protrusion and flip the anti-counterfeiting key to see the anti-counterfeiting verification code imprint layer and fluorescent anti-counterfeiting coating. Pulling out the anti-counterfeiting key will damage the fragile paper layer and the thermochromic filler layer. Once the fragile paper layer and the thermochromic filler layer are damaged, they are difficult to restore. In addition, this utility model also embeds a passive electronic anti-counterfeiting label in the positioning groove at a local position on the upper surface of the positioning base layer. The passive electronic anti-counterfeiting label has good concealment. The combination of multiple anti-counterfeiting structures and methods is novel, with good anti-counterfeiting effect, simple identification, convenient use, and good practicality.
