Description

Technical Field

[0001] The utility model relates to the technical field of anti-counterfeiting labels, in particular to a light-variable anti-counterfeiting label. Background Art

[0002] An anti-counterfeiting mark is a mark that can be pasted on the surface of an object or on an accessory on a package to prevent counterfeiting. A light-variable anti-counterfeiting label is a type of label that has a light-variable anti-counterfeiting layer inside, which makes it easy to identify.

[0003] For example, the utility model: "A new type of optically variable anti-counterfeiting label", with the announcement number: "CN209373925U", improves the stability of the connection between the support layer and the second reinforcement layer by setting an adhesive layer, and improves the sealing and waterproof performance of the optically variable anti-counterfeiting label by setting a polyurethane sealing layer. However, during the implementation of this patent, the structural strength of the optically variable anti-counterfeiting label is only improved by using a polyamide reinforcement layer and a polycarbonate reinforcement layer, which cannot effectively buffer the external extrusion force, and cannot help the optically variable anti-counterfeiting label to recover elastically after the extrusion. Its anti-extrusion effect is poor, and the protection effect on the optically variable anti-counterfeiting layer is poor. Therefore, a new type of optically variable anti-counterfeiting label is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a light-variable anti-counterfeiting label to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photovariable anti-counterfeiting label, comprising a photovariable anti-counterfeiting label plastic shell, a first groove and a photovariable anti-counterfeiting layer, a second groove is arranged at the bottom of the photovariable anti-counterfeiting label plastic shell, and an adhesive layer is arranged inside the second groove, a waterproof sealing slot is arranged at the edge position of the top of the photovariable anti-counterfeiting label plastic shell, and a transparent waterproof patch is installed on the top of the photovariable anti-counterfeiting label plastic shell, a photovariable anti-counterfeiting layer is arranged inside the photovariable anti-counterfeiting label plastic shell, and first grooves are arranged at both ends of the photovariable anti-counterfeiting label plastic shell, and label protection outer patches are installed at both ends of the photovariable anti-counterfeiting label plastic shell.

[0006] Preferably, semicircular rubber sheets are evenly installed inside the first grooves, the semicircular rubber sheets are connected to the label protection outer patch, and two groups of elastic rubber sheets are installed on the inner side of the semicircular rubber sheets, and the ends of the elastic rubber sheets away from the semicircular rubber sheets are connected to the plastic shell of the optically variable anti-counterfeiting label.

[0007] Preferably, an adhesive layer protective patch is installed at the bottom of the adhesive layer.

[0008] Preferably, a modified polyphenylene ether support layer is provided at the bottom of the interior of the optically variable anti-counterfeiting label plastic shell, and a carbon fiber reinforcement layer is provided on the top of the modified polyphenylene ether support layer, and the carbon fiber reinforcement layer is connected to the optically variable anti-counterfeiting layer.

[0009] Preferably, a waterproof rubber insert is installed at the edge of the bottom of the transparent waterproof patch.

[0010] Preferably, an anti-slip strip is installed at one end of the adhesive layer protection patch, and anti-slip protrusions are evenly arranged on the outer side of the anti-slip strip.

[0011] Preferably, the cross-section of the elastic rubber sheet is in an "S" shape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The optically variable anti-counterfeiting label is equipped with a semicircular rubber sheet, an elastic rubber sheet and a label protection outer patch. When in use, if the plastic shell of the optically variable anti-counterfeiting label is subjected to external extrusion force, the label protection outer patch can be forced to squeeze the semicircular rubber sheet and the elastic rubber sheet, so that the semicircular rubber sheet and the elastic rubber sheet are deformed under force, which can buffer the extrusion force and have a better protection effect on the optically variable anti-counterfeiting layer. After the extrusion is completed, the elasticity of the semicircular rubber sheet and the elastic rubber sheet can also help the label protection outer patch to recover;

[0014] 2. The optically variable anti-counterfeiting label is equipped with a carbon fiber reinforcement layer and a modified polyphenylene ether support layer. The carbon fiber reinforcement layer and the modified polyphenylene ether support layer can improve the structural strength of the plastic shell of the optically variable anti-counterfeiting label, and can effectively improve the compression resistance of the plastic shell of the optically variable anti-counterfeiting label, thereby preventing the plastic shell of the optically variable anti-counterfeiting label from being damaged by external forces;

[0015] 3. The optically variable anti-counterfeiting label is installed with a transparent waterproof patch and a waterproof rubber insert. The transparent waterproof patch improves the waterproof effect, and the waterproof rubber insert is inserted into the waterproof sealing slot. The waterproof rubber insert blocks the gap between the transparent waterproof patch and the plastic shell of the optically variable anti-counterfeiting label, so that external liquid cannot enter the plastic shell of the optically variable anti-counterfeiting label through the gap between the transparent waterproof patch and the plastic shell of the optically variable anti-counterfeiting label, which can further improve the waterproof sealing.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In this implementation:

[0024] Furthermore, semicircular rubber sheets 2 are evenly installed inside the first groove 3, and the semicircular rubber sheets 2 are connected to the label protection outer patch 15, and two groups of elastic rubber sheets 13 are installed on the inner side of the semicircular rubber sheets 2, and the ends of the elastic rubber sheets 13 away from the semicircular rubber sheets 2 are connected to the light-variable anti-counterfeiting label plastic shell 1. When in use, if the light-variable anti-counterfeiting label plastic shell 1 is subjected to external squeezing force, the label protection outer patch 15 can be squeezed by the semicircular rubber sheet 2 and the elastic rubber sheet 13, so that the semicircular rubber sheet 2 and the elastic rubber sheet 13 are deformed under the force, which can buffer the squeezing force and have a better protection effect on the light-variable anti-counterfeiting layer 6. After the squeezing is completed, the elasticity of the semicircular rubber sheet 2 and the elastic rubber sheet 13 can also help the label protection outer patch 15 to recover.

[0025] Furthermore, an adhesive layer protection patch 11 is installed at the bottom of the adhesive layer 10 , and the adhesive layer 10 is protected by the adhesive layer protection patch 11 , so as to prevent external liquid and dust from adhering to the adhesive layer 10 .

[0026] Furthermore, a modified polyphenylene ether supporting layer 14 is provided at the bottom of the inner part of the optically variable anti-counterfeiting label plastic shell 1, and a carbon fiber reinforcing layer 7 is provided on the top of the modified polyphenylene ether supporting layer 14, and the carbon fiber reinforcing layer 7 is connected to the optically variable anti-counterfeiting layer 6.

[0027] Furthermore, a waterproof rubber strip 8 is installed at the edge of the bottom of the transparent waterproof patch 5, and the waterproof rubber strip 8 is inserted into the waterproof sealing slot 4. The waterproof rubber strip 8 blocks the gap between the transparent waterproof patch 5 and the optically variable anti-counterfeiting label plastic shell 1, so that external liquid cannot enter the interior of the optically variable anti-counterfeiting label plastic shell 1 through the gap between the transparent waterproof patch 5 and the optically variable anti-counterfeiting label plastic shell 1, which can further improve the waterproof sealing performance.

[0028] Furthermore, an anti-slip strip 9 is installed at one end of the adhesive layer protection patch 11 , and anti-slip protrusions are evenly arranged on the outer side of the anti-slip strip 9 , so as to facilitate tearing off the adhesive layer protection patch 11 from the outer side of the adhesive layer 10 .

[0029] Furthermore, the cross-sectional shape of the elastic rubber sheet 13 is “S”-shaped.

[0030] Working principle:

[0031] When in use, the adhesive layer protection patch 11 can be torn off from the outside of the adhesive layer 10 through the anti-slip strip 9, and then the optically variable anti-counterfeiting label plastic shell 1 can be pasted to the designated position through the adhesive layer 10;

[0032] During use, the transparent waterproof patch 5 can prevent liquid from contacting the optically variable anti-counterfeiting layer 6, which can effectively improve the waterproof effect, and the waterproof rubber insert 8 is inserted into the waterproof sealing slot 4, and the gap between the transparent waterproof patch 5 and the optically variable anti-counterfeiting label plastic shell 1 is blocked by the waterproof rubber insert 8, so that external liquid cannot enter the optically variable anti-counterfeiting label plastic shell 1 through the gap between the transparent waterproof patch 5 and the optically variable anti-counterfeiting label plastic shell 1, which can further improve the waterproof sealing performance;

[0033] When the light-variable anti-counterfeiting label plastic shell 1 is subjected to external squeezing force, the label protection outer patch 15 can be subjected to the force to squeeze the semicircular rubber sheet 2 and the elastic rubber sheet 13, so that the semicircular rubber sheet 2 and the elastic rubber sheet 13 are deformed by the force, which can buffer the squeezing force and have a better protection effect on the light-variable anti-counterfeiting layer 6. After the squeezing is completed, the elasticity of the semicircular rubber sheet 2 and the elastic rubber sheet 13 can also help the label protection outer patch 15 to recover;

[0034] The carbon fiber reinforcement layer 7 and the modified polyphenylene ether support layer 14 can improve the structural strength of the optically variable security label plastic shell 1, effectively improve the compression resistance of the optically variable security label plastic shell 1, and prevent the optically variable security label plastic shell 1 from being damaged by external forces.
