Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive stickers, in particular to a temperature-variable anti-counterfeiting self-adhesive sticker. Background Art

[0002] Self-adhesive labels, also known as self-adhesive labels, instant stickers or pressure-sensitive labels, are a type of material widely used in various packaging, product identification, advertising and other fields. Self-adhesive labels are mainly composed of face material, adhesive, backing paper and other parts. The face material is the surface layer of the self-adhesive label, the part that is in direct contact and displayed to the user. The face material is made of a variety of materials, including but not limited to paper, film and special materials. The adhesive is the key part of the self-adhesive label. It is located between the face material and the backing paper, and can achieve a firm bond with the adhesive surface by applying a certain amount of pressure. There are also many types of adhesives, including permanent, removable, re-stickable and other types to meet different pasting requirements and removal methods. Among them, temperature change and anti-counterfeiting are important functions of self-adhesive labels.

[0003] For example, the Chinese patent "Anti-counterfeiting Self-adhesive Label" with publication number CN219039925U includes a self-adhesive layer, a REFD label layer is fixedly connected to the upper part of the self-adhesive layer, an anti-counterfeiting code layer is provided on the outer side of the REFD label layer, an organic temperature-sensitive color-changing layer is fixedly connected to the outer side of the anti-counterfeiting code layer, a fluorescent powder is provided on the surface of the anti-counterfeiting code layer, a strength layer is fixedly connected to the outer side of the REFD label layer, the strength layer is arranged between the anti-counterfeiting code layer and the self-adhesive layer, high-strength wire is provided inside the strength layer, the high-strength wire is woven into a mesh structure, a thermal insulation layer is provided on the outer side of the REFD label layer, the thermal insulation layer is fixedly connected to the upper surface of the strength layer, a transparent layer is fixedly connected to the outer side of the organic temperature-sensitive color-changing layer, a waterproof membrane layer is fixedly connected to the outer side of the transparent layer, a release paper layer is provided on the bottom surface of the self-adhesive layer, an open strip is provided at one end of the release paper layer, the REFD label layer is arranged in the middle of the strength layer, and the waterproof membrane layer has the same shape as the transparent layer.

[0004] Although the above-mentioned existing technology can realize the use of self-adhesive stickers, in actual use, on the one hand, the surface of the self-adhesive sticker is easily damaged. When the self-adhesive sticker encounters external friction during pasting, the surface layer of the self-adhesive sticker is damaged, thereby shortening the service life of the self-adhesive sticker. On the other hand, the self-adhesive sticker is prone to weakening in viscosity after long-term use. The self-adhesive sticker is easily contaminated with dust and impurities on the pasting surface after being torn off and pasted again many times, resulting in a decrease in the viscosity of the self-adhesive sticker layer, thereby reducing the pasting effect of the self-adhesive sticker. Therefore, it does not meet the existing needs. In this regard, we have proposed a temperature-changing anti-counterfeiting self-adhesive sticker. Utility Model Content

[0005] The purpose of the utility model is to provide a temperature-variable anti-counterfeiting sticker to solve the problems in the above background art that the sticker surface is easily damaged and the sticker loses its stickiness after long-term use.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a temperature-changing anti-counterfeiting self-adhesive sticker, comprising two adhesive layers, a temperature-changing layer is arranged between the adhesive layers, the temperature-changing layer is connected to the adhesive layer through a polymer adhesive, a protective layer is arranged at the upper end of the adhesive layer above the temperature-changing layer, and an adhesion layer is arranged at the lower end of the adhesive layer below the temperature-changing layer, and the adhesion layer is connected to the adhesive layer through a polymer adhesive.

[0007] Preferably, an anti-counterfeiting coding layer is provided inside the protective layer located at the upper end of the adhesive layer, and the anti-counterfeiting coding layer is connected to the adhesive layer via a polymer adhesive.

[0008] Preferably, a waterproof layer is provided inside the protective layer located on the upper end of the anti-counterfeiting code layer, and the waterproof layer is sprayed on the upper end of the anti-counterfeiting code layer by a spraying device.

[0009] Preferably, the protective layer is provided with a wear-resistant layer inside the upper end of the waterproof layer, the wear-resistant layer is sprayed on the upper end of the waterproof layer by spraying equipment, the upper end of the wear-resistant layer is provided with an external isolation layer, and the external isolation layer and the wear-resistant layer are connected by an adhesive.

[0010] Preferably, an adhesion-promoting layer is provided inside the adhesive layer at the lower end of the adhesive layer, and the adhesion-promoting layer is connected to the adhesive layer via a polymer adhesive.

[0011] Preferably, an anti-fouling layer is provided inside the adhesion layer located at the lower end of the adhesion-promoting layer, and the anti-fouling layer is sprayed on the lower end of the adhesion-promoting layer by a spraying device.

[0012] Preferably, an internal isolation layer is provided at the lower end of the anti-fouling layer, and the internal isolation layer is connected to the anti-fouling layer by an adhesive.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can improve the protection of the adhesive layer by providing a protective layer. When using the self-adhesive sticker, the outer isolation layer on the outermost side of the protective layer is torn off, and then the self-adhesive sticker is adhered to the adhesive surface. At this time, the wear-resistant layer provided inside the protective layer can improve the wear resistance of the surface of the self-adhesive sticker, provide a certain degree of protection when the self-adhesive sticker is subjected to friction, avoid the adhesive layer from being damaged after being subjected to friction, so that the adhesion of the adhesive layer will not be affected by friction. At the same time, the waterproof layer provided under the wear-resistant layer can avoid moisture from contacting the adhesive layer of the self-adhesive sticker, and prevent the situation where moisture directly contacts the adhesive layer when the self-adhesive sticker is used in a humid environment, thereby reducing the adhesion effect of the adhesive layer, so that the self-adhesive sticker can adapt to different working environments.

[0015] 2. The utility model can enhance the adhesion effect of the adhesive layer by providing an adhesive layer. When using the self-adhesive label, the innermost internal isolation layer of the adhesive layer is torn off, and then the self-adhesive label is adhered to the adhesive surface. The anti-fouling provided at this time can prevent dust and other impurities on the adhesive surface from directly contacting the adhesive layer, thereby improving the adhesion effect of the adhesive layer. At the same time, the provided adhesion-promoting layer can improve the adhesion effect of the adhesive layer. When the position of the self-adhesive label is changed, it is necessary to tear off the self-adhesive label multiple times and then stick it on other adhesive surfaces. The provided adhesion-promoting layer can enable the adhesive layer to maintain a certain viscosity during the process of multiple tearing and sticking, thereby preventing the adhered self-adhesive label from falling off.

[0016] 3. The present invention provides an anti-counterfeiting function to the self-adhesive label by providing a temperature-variable layer and an anti-counterfeiting coding layer. The temperature-variable layer can effectively prevent the emergence of counterfeit and inferior products. Since the color change of the temperature-variable layer is unique and cannot be replicated, it can be used as a mark of authenticity. When consumers or regulatory agencies verify the label through temperature changes, if the label does not change color as expected, it is likely a counterfeit product. At the same time, the anti-counterfeiting coding layer provided above the temperature-variable layer can enhance the anti-counterfeiting performance of the self-adhesive label. When passing the temperature detection, only the base color of the anti-counterfeiting coding layer changes, and it will not cause identification interference on the anti-counterfeiting coding layer.
