Description

Anti-counterfeit labels

This creation is related to a label, especially a label with anti-counterfeiting function.

In order to enable consumers to identify the authenticity of products, many companies try to mark their own products with anti-counterfeit labels. Most of the commonly known anti-counterfeit labels are laser anti-counterfeit labels, which can be seen on the label by adjusting the direction of sight or the direction of the light source. Color effects or different patterns; or by zooming in on a local location, check to see if the location has a special pattern. However, due to the increasingly advanced printing technology, it is difficult to ensure the uniqueness of the laser anti-counterfeiting label, and it is easy to be copied.

Counterfeiting means that in order to increase sales, operators use other operators' unique and well-known registered trademarks, product packaging, decoration, names or various quality signs without consent, causing confusion among consumers and market confusion, in order to gain profits. Acts of illegitimate interests are extremely harmful to market competition.

What's more, counterfeit and counterfeit products with low-quality materials are used to fake the appearance and brand of genuine products, and use the corporate image or advertising benefits of genuine products to increase the sales profit and sales volume of counterfeit products. In the past, not only the image of genuine products in the market has been damaged, but the inferior quality of counterfeit products will also endanger the health or safety of the public, causing panic among the general public.

Therefore, only by possessing a set of unique anti-counterfeiting technology can we effectively create the value of commodities, and we can combine technology and experience in various fields to establish multiple technical thresholds and develop Exhibiting solutions that can truly prevent counterfeit goods and product control, and at the same time meet the needs of establishing a good corporate brand image and logistics control.

In order to solve the above problems, this invention provides a label with anti-counterfeiting function, including a color-changing layer and a marking layer. The color-changing layer includes an upper surface and a first connecting surface. The color-changing layer at least includes a color-changing material, which can change from a first color to a second color. The marking layer includes a lower surface and a second connecting surface, the first connecting surface and the second connecting surface adhere to each other, and the marking layer at least contains biomarker material.

In some embodiments, the color-changing material of the label with anti-counterfeiting function can change from a first color to a second color when exposed to light, and the light can be sunlight or ultraviolet light. In some embodiments, the color-changing material of the anti-counterfeit label can change from the second color back to the first color when light is removed. For example, the color-changing material may be a photochromic material, or a temperature-sensitive material containing a thermochromic material.

In some embodiments, the color-changing material of the anti-counterfeiting label exhibits a first color at ordinary times, and a second color when the ambient temperature changes to a specific temperature range, and the specific temperature range is between 30°C and 40°C. In some embodiments, the color-changing material exhibits a first color corresponding to outside the specified temperature range.

In some embodiments, the biomarker material of the anti-counterfeit label is a gene fragment, and the gene fragment can be from an animal, plant, bacterium, virus or artificially synthesized vector. In some embodiments, the gene segment in the anti-counterfeiting label is DNA or RNA including a specific sequence.

In some embodiments, the anti-counterfeiting label further includes a light-transmitting protective film attached to the upper surface. In some embodiments, the light-transmissive protective film is transparent.

In some embodiments, the anti-counterfeiting label includes a substrate that is removably attached to the lower surface. In some embodiments, the substrate can be made of plastic or paper.

In some embodiments, an anti-counterfeiting label identification system includes: an anti-counterfeiting label, a primer, a polymerase chain reaction detector, and an electrophoresis tank. Anti-counterfeiting tags include biomarker materials with specific sequences. Primers are complementary to specific sequences. The polymerase chain reaction detector uses primers to replicate the biomarker material. The electrophoresis tank separates the copied biomarker materials with film, and judges whether the biomarker materials are correct according to the state of the film. The presence of the gene fragment is detected by electrophoresis to confirm the authenticity of the label.

In some embodiments, the anti-counterfeiting label identification system further includes a dye for tracking the position of the biomarker material on the film. In some embodiments, the staining agent can be ethidium bromide (EtBr), and the staining agent can confirm whether the gene fragment exists or whether the position of the gene fragment is as expected.

In some embodiments, the advantage of the anti-counterfeiting label and its identification system provided by the invention is that consumers can easily identify the authenticity of the product through the color-changing layer, such as the anti-counterfeiting label containing the photochromic layer. With functional labels, consumers can confirm the color change of the label through sunlight; or with temperature-sensitive anti-counterfeiting labels, consumers can confirm the color change of the label through the temperature of the palm. Furthermore, product control personnel can directly dye the anti-counterfeiting label through EtBr, and confirm the coloring position of the gene fragment The source of the product to prevent product violations. Therefore, the anti-counterfeit labels provided by this creation can not only allow consumers to easily identify and enhance consumers' confidence in the product, but also allow enterprises to establish good logistics control.

In some embodiments, the principle of using ethidium bromide (EtBr) as a dye can be used to first confirm whether the gene fragment exists or whether the position of the gene fragment is correct, so as to confirm the authenticity in the fastest way. In addition, if there is any doubt about counterfeit products, PCR reactions can be carried out with primers complementary to specific sequences, and the presence of gene fragments can be detected by electrophoresis to confirm the authenticity of the tags.

In some embodiments, gene fragments are used as the genetic material of most organisms to form genetic information to guide the development of organisms and the operation of life functions. The main function is the storage of long-term genetic information; and ethidium bromide , EtBr) is currently mainly used as a dye, and the position of the gene fragment can be tracked during electrophoresis. Because of its flat structure, it can be embedded between the base pairs in the gene fragment structure and closely combined with it. After being irradiated by ultraviolet light, the gene fragment will absorb light of ultraviolet wavelength, and then emit light of visible wavelength through EtBr.
