Description

Technical Field

[0001] The present invention belongs to the technical field of texture anti-counterfeiting, and relates to a texture material for a random texture anti-counterfeiting label, a manufacturing method of the random texture anti-counterfeiting label, the obtained random texture anti-counterfeiting label, a random texture anti-counterfeiting label including the texture material, and an anti-counterfeiting system including the random texture anti-counterfeiting label. Background Art

[0002] Texture anti-counterfeiting means that the image information of the texture material randomly distributed on the random texture anti-counterfeiting label is stored in a database in advance. During identification, the image information in the database is retrieved and compared to determine the authenticity of the product.

[0003] However, in the actual use process, if the quantity of the texture material distributed on the random texture anti-counterfeiting label is limited, for high-value-added products, counterfeiters can imitate by arranging the distribution of the texture material. Therefore, in order to ensure the anti-counterfeiting effect, the applicant of the present application thought of increasing the quantity of the texture material distributed per unit area on the random texture anti-counterfeiting label to increase the arrangement difficulty and make counterfeiters have no profit to gain. However, increasing the distribution density will result in a very small interval or even an overlapping phenomenon between the texture materials with anti-counterfeiting features. The adjacent texture materials with anti-counterfeiting features or the overlapping texture materials with anti-counterfeiting features will affect the acquisition of image information, and at the same time, will also affect the observation of whether there are inherent identification features on the texture material itself, thus seriously interfering with the identification of the random texture anti-counterfeiting label and even causing the serious consequence of being unable to identify.

[0063] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below. Based on the specific embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present invention.

[0064] Before describing the specific embodiments, the following limitations are made on the directional terms appearing in the present invention:

[0065] When the texture material provided by the present invention is in normal use, after it lands on the bearing surface of the carrier of the random texture anti - counterfeiting label, the surface that fits with the bearing surface is the lower surface, the surface that faces away from the bearing surface is the upper surface, and the surfaces other than the upper surface and the lower surface are side surfaces, and the side surfaces include all side end faces.

[0066] For better understanding, the following will be described and introduced by way of specific embodiments in conjunction with the drawings.

[0067] Example 1

[0068] This embodiment provides a texture material for a random texture anti - counterfeiting label, including a texture body and a spacing part; wherein, the spacing part is formed on the outside of at least one side end face of the texture body, the texture body includes a visual feature material part with anti - counterfeiting features, and the spacing part is a structure that enables the texture body of the texture material to space the texture material adjacent to the random texture anti - counterfeiting label.

[0069] When manufacturing a random texture anti - counterfeiting label with this texture material, the spacing part can space the texture bodies with anti - counterfeiting features of two adjacent texture materials, making the anti - counterfeiting features of the texture body easier to identify.

[0070] Example 1

[0071] Such as Figure 1-1As shown in the figure, it is a top view of the texture material 1 for the random texture anti-counterfeiting label. When observing the texture material 1 from the upper surface downwards, it is rectangular. The texture material 1 includes a texture body 2 and a spacer 3. Among them, spacers 3 are formed on the outer sides of the two opposite side end faces of the texture body 2. The texture material 1 with such a structure is convenient for processing and manufacturing. The texture body 2 includes a visual feature material part with anti-counterfeiting features, and the spacer is a structure that enables the texture body of the texture material to space the texture materials adjacent to the random texture anti-counterfeiting label.

[0072] After making the Figure 1-1 texture material into a random texture anti-counterfeiting label, it can be seen from Figure 2 that the spacer plays a role in spacing the texture bodies of two adjacent texture materials. In this way, when the storage acquisition module acquires and stores the random texture distribution image information and / or stores the random texture distribution feature information, and the recognition acquisition module obtains the to-be-recognized random texture distribution image information and / or to-be-recognized random texture distribution feature information of the to-be-recognized random texture anti-counterfeiting label, it is more conducive to the acquisition of the image information and distribution feature information. Therefore, the texture bodies are spaced from each other and are easier to distinguish.

[0073] In this example, spacers 3 are adhesively bonded to the outer sides of the two side end faces of the texture body 2. Optionally, the texture body 2 and the spacer 3 are integrally formed during the melt spinning process. Optionally, the connection surface between the texture body 2 and the spacer 3 is a connection surface formed in a molten state.

[0074] Preferably, in this example, the maximum geometric dimension of the texture material 1 is not greater than 1 mm. In this way, when densely distributed on the carrier, the number of texture materials per unit area can be increased, improving the dispersion density and effectively preventing the imitation of anti-counterfeiting labels by placing texture materials.

[0075] In this example, the spacer 3 is preferably made of a transparent material to reduce the influence on the visual features of the texture body 2.

[0076] In this example, when the texture material is made by the method of melt spinning plus slicing, the cutting surface is the upper surface and / or the lower surface. This way of preparing the texture material is easy to process.

[0077] In this example, visual feature parts with anti-counterfeiting features can be distributed on the side end faces of the texture body. In this way, for a single texture material, it has a three-dimensional visual color feature to further prevent imitation by printing, printing, engraving, molding, etc.

[0078] In this example, an optional case is that the spacer portion 3 is made of a soluble material that can be dissolved in the first solvent, and the texture body 2 is made of an insoluble material that is insoluble in the first solvent. In this way, under the action of the first solvent, the spacer portion 3 of the texture material that has been distributed on the bearing surface of the random texture anti-counterfeiting mark can be dissolved. First, the spacer portion 3 can be removed to eliminate the influence of the spacer portion 3 on the anti-counterfeiting features of the anti-counterfeiting body 2. Second, the anti-counterfeiting features on the side end faces of the texture body 2 are highlighted, giving it a three-dimensional visual color feature to further prevent imitation by printing, printing, engraving, molding, etc. Among them, the first solvent can be water, alkaline water, organic solvents, etc. The organic solvents here can be, for example, ethyl acetate, alcohol, benzene solvents, etc. In this example, the texture body 2 and the isolation portion 3 are two different polymer materials. The isolation portion 3 can be a water-soluble material, and the texture body 2 is a polyester material or a polyethylene material.

[0079] Example 2

[0080] As Figure 1-2 shown is a top view of another texture material 1. The difference between this example and Example 1, Case 1 is that when observing from above the upper surface of the texture material 1, the texture material 1 is oval; the axis of the texture body 2 is parallel to the long axis of the ellipse, and spacer portions 3 are formed on the outer sides of two opposite side end faces of the texture body 2. Compared with Case 1, this example can increase the distribution density of the texture body 2 on the bearing surface of the random texture anti-counterfeiting mark, making it more difficult for counterfeiters to place, and making it unprofitable for counterfeiters.

[0081] Example 3

[0082] As Figure 1-3 shown is a top view of the third texture material 1. The difference between this example and Example 1, Case 2 is that in this example, when observing from above the upper surface of the texture material 1, the texture material 1 is oval, the texture body 2 is a small oval surrounded by the isolation portion 3, and the isolation portion 3 is in an elliptical ring shape. Compared with Case 2 of Example 1, spacer portions 3 are formed on the outer sides of all side end faces (i.e., side surfaces) of the texture body 2, so that the texture bodies of adjacent texture materials can be effectively spaced from each other in all directions.

[0083] Example 4

[0084] As Figure 7As shown, it is the front view of a part of the texture body 2 in the texture material. In the figure, the texture body 2 is located on the bearing surface of the carrier 4. The texture body 2 adopts a three-dimensional light-angle color-changing structure. The texture body 2 distributes two visually different color material parts, namely the first visual color part 11 and the second visual color part 12, on two opposite side end surfaces. When the observer observes the texture body 2 from the side of the first visual color part 11 above the bearing surface, the color of the first visual color part 11 is shown; when the observer observes the texture body from the side of the second visual color part 12 above the bearing surface, the color of the second visual color part 12 is shown. For example: the first visual color part shows red, and the second visual color part shows blue; then when observing the texture body 2 from the side of the first visual color part above the bearing surface, it shows red; when observing the texture body 2 from the side of the second visual color part above the bearing surface, it shows blue.

[0085] The texture material using the texture body in this example can further prevent imitation in printing, printing, engraving, embossing, etc.

[0086] Example 5

[0087] As Figure 8 shown, it is the front view of a part of the texture body 2 in the texture material. In the figure, the texture body 2 is located on the bearing surface of the carrier 4. The texture body 2 adopts a three-dimensional visual color structure. Among them, the upper surface 8 of the texture body 2 distributes the first visual color part, and the side end surface 9 of the texture body 2 distributes the second visual color part. The two visual color parts present their respective visual colors. For example: the first visual color part distributed on the upper surface 8 of the texture body 2 presents red, and the second visual color part distributed on the side end surface of the texture body 2 presents black; when a large number of texture materials 1 are distributed on the bearing surface of the carrier, there is at least one inclination angle above the bearing surface. The overall visual color formed by observing the texture body of the large number of texture materials distributed on the bearing surface at this inclination angle is visually distinguishable from the overall visual color formed by observing the texture body of the large number of texture materials distributed on the bearing surface in the vertical direction perpendicular to the bearing surface above the bearing surface; among them, for the non-contact surface of each texture body, a first visual image is formed by observing in the vertical direction, and a second visual image is formed by observing at the inclination angle and around the circumference of the texture body. Among them, the area ratio of at least one visual color part in the first visual image is different from its area ratio in the second visual image, so that the first visual image and the second visual image present a visual color difference;

[0088] Among them, the other surfaces (upper surface plus side surface) of the texture body 2 except the lower surface are the non-contact surfaces of the texture body.

[0089] It should be noted here that the principle of the human eye to recognize color changes is as follows: at the normal viewing distance of the human eye, when the visual spacing angle between adjacent different visual color parts is less than 1", the human eye cannot separately recognize the two visual color parts, but can only see the visual color mixing effect formed by the two visual color parts. When the texture body of the texture material in this example is recognized at the normal viewing distance of the human eye, its overall visual spacing angle is much less than 1", so when directly observed by the human eye, only the visual color mixing effect can be seen.

[0090] When the human eye can only recognize the visual color mixing effect and the color shades of different visual color parts are certain, the main factor determining the color change recognized by the human eye is the area ratio of different visual color parts.

[0091] In summary, when the area ratio of a certain visual color part in the first visual image changes from that in the second visual image, it is certain that there is a certain visual difference between the visual color presented by the first visual image and the visual color presented by the second visual image.

[0092] This kind of texture material is not limited to Figure 8 the texture material shown in

[0093] All texture materials that meet the following conditions can achieve the above effects, that is:

[0094] The visual feature material part of the texture body is the visual color part. At least two visual color parts are included on the non-contact surface of each texture body. Each of the visual color parts presents its own visual color, so that there is at least one inclination angle above the bearing surface. When observing the overall visual color formed by the texture bodies of a large number of the texture materials distributed on the bearing surface at this inclination angle, there is a visually distinguishable visual color difference from the overall visual color formed by observing the texture bodies of a large number of the texture materials distributed on the bearing surface in the vertical direction perpendicular to the bearing surface above the bearing surface; wherein, for the non-contact surface of each texture body, a first visual image is formed by observing in the vertical direction, and a second visual image is formed by observing at the inclination angle and around the circumference of the texture body. Among them, the area ratio of at least one visual color part in the first visual image is different from its area ratio in the second visual image, so that the first visual image and the second visual image present a visual color difference;

[0094] Among them, the other surfaces (the upper surface plus the side surfaces, where the side surfaces include all side end faces) of the texture body except the lower surface are the non-contact surfaces of the texture body.

[0095] Examples 1 to 3 above give three examples of the texture material 1, and Examples 4 and 5 give examples of the texture body 2 of the texture material 1. Of course, the cross-section of the texture material (parallel to the upper or lower surface) is not limited to a rectangle or an ellipse, and can also be other shapes such as a circle or a polygon. The texture body 2 in Examples 4 and 5 has a stereoscopic vision feature, which further prevents imitation by printing, printing, engraving, or molding. Of course, the texture body 2 can also adopt a texture body without a visual feature part on its side end face.

[0096] Example 2

[0097] This embodiment provides a method for manufacturing a random texture anti-counterfeiting label, which utilizes the texture material described in Embodiment 1. The random texture anti-counterfeiting label made of the above-mentioned texture material 1 can improve the distribution density of the texture material on the carrier, and at the same time ensure that there is no overlap between the texture materials, and there is a gap between the texture bodies, making the visual features of the texture bodies easier to be recognized and collected.

[0098] Example 1

[0099] A method for manufacturing a random texture anti-counterfeiting label, the random texture anti-counterfeiting label is made of the texture material described in Embodiment 1, the random texture anti-counterfeiting label includes a carrier 4 and a texture material 1, and the carrier 4 includes a material layer 5 and an adhesive layer 6 (such as Figure 6 ); The method includes:

[0100] Step 1: Stack a large number of texture materials 1 in Embodiment 1 on the adhesive layer 5 of the carrier 4;

[0101] Step 2: Spread the texture material on the adhesive layer 6 of the carrier, and remove the texture material 1 that is not adhered to the adhesive layer 6 of the carrier;

[0102] Wherein, the lower surface of the texture material 1 is bonded and fixed to the adhesive layer 6.

[0103] Stacking a large number of texture materials on the adhesive layer 6 of the carrier can ensure the distribution density of the subsequent texture materials 1 on the adhesive layer of the carrier. The spreading action can achieve: (1) removing the texture material that is not adhered to the adhesive layer 6 of the carrier from the adhesive layer 6; (2) spreading the texture material 1 remaining on the adhesive layer 6 of the carrier into a non-overlapping single-layer state. In this way, it effectively ensures that the texture materials 1 are densely distributed on the adhesive layer 6 of the carrier without overlapping. The spreading action can be implemented manually or mechanically.

[0104] Wherein, the step of "removing the texture material that is not adhered to the adhesive layer" can specifically be "sucking off or blowing off the texture material that is not adhered to the adhesive layer through a suction fan or a hair dryer".

[0105] In this way, for the randomly textured anti-counterfeiting label prepared, firstly, it ensures that the textured materials are densely and non-overlappingly distributed on the adhesive layer of the carrier; secondly, due to the presence of the spacer part, there is a gap between the textured bodies of adjacent textured materials, making the visual color of the textured bodies more prominent, which is conducive to the recognition and collection by the collector. In other words, the textured materials can be made smaller, and a larger number of textured fibers can be distributed per unit area, increasing the difficulty for counterfeiters to place them. At the same time, when the visual feature of the textured body is a three-dimensional visual feature, it further prevents imitation by printing, printing, engraving, and molding.

[0106] Preferably,

[0107] After step 2, it further includes step 4: coating a layer on the side of the adhesive layer 6. This coating covers the adhesive layer and the textured materials 1 bonded thereon to strengthen the adhesion of the textured materials to the adhesive layer and prevent the textured materials from falling off the adhesive layer.

[0108] More preferably, the coating is a UV curable material layer or an AB glue layer.

[0109] In this embodiment, the material layer 5 and the adhesive layer 6 are made of different materials, but the material layer 5 and the adhesive layer 6 can also be made of the same material. For example, one side of the material layer 5 is melted to form the adhesive layer.

[0110] The prepared randomly textured anti-counterfeiting label, such as Figure 2 and Figure 3 , Figure 3 The randomly textured anti-counterfeiting label in also includes a corresponding code, such as a two-dimensional code, relative to Figure 2

[0111] Example 2

[0112] The difference between this example and Example 1 of Embodiment 2 is that in this example, the spacer part 3 is made of a soluble material that can be dissolved in the first solvent, and the textured body 2 is made of an insoluble material that is insoluble in the first solvent;

[0113] Then after step 2, it further includes:

[0114] Step 3: Using the first solvent to dissolve the spacer part of the textured materials bonded to the adhesive layer.

[0115] The visual feature of the side end face of the textured body 2 with the spacer part 3 dissolved is more prominent.

[0116] Similarly, preferably, after step 3, it can further include step 4:

[0117] ​Apply a layer of coating on the adhesive layer side. This coating covers the adhesive layer 6 and the textured material 1 adhered thereto, so as to strengthen the adhesion of the textured material 1 on the adhesive layer 6 and prevent the textured material 1 from peeling off the adhesive layer 6.

[0118] Further preferably, the coating is a UV curable material layer or an AB glue layer.

[0119] In this embodiment, the material layer 5 and the adhesive layer 6 are made of different materials, but the material layer 5 and the adhesive layer 6 can also be of the same material. For example, one side of the material layer 5 is melted to form the adhesive layer 6.

[0120] In this embodiment, "removing the textured material that is not adhered to the adhesive layer of the carrier" in step 2 includes blowing it away with a hair dryer or sucking it away with a suction fan.

[0121] The obtained random texture anti-counterfeiting label such as 4 and Figure 5 , Figure 5 The random texture anti-counterfeiting label in is relative to Figure 4 It also includes a corresponding code, such as a two-dimensional code.

[0122] Example 3

[0123] This embodiment provides a random texture anti-counterfeiting label, which is a random texture anti-counterfeiting label (such as Figure 2 and Figure 3 ) without removing the spacer 3 prepared by the method of Example 1 in Example 2 and a random texture anti-counterfeiting label (such as Figure 4 and Figure 5 ) with the spacer 3 removed prepared by the method of Example 2 in Example 2. Due to the adoption of the method of Example 2, the same beneficial effects are obtained. See Example 2 and will not be elaborated here.

[0124] Preferably, in the manufacturing method of the random texture anti-counterfeiting label in Example 2, the light-angle color-changing texture body 2 of Example 4 in Example 1 is adopted. That is to say, the texture body of the textured material included in the random texture anti-counterfeiting label in this embodiment is the light-angle color-changing texture body 2 of Example 4 in Example 1. In this way, the obtained random texture anti-counterfeiting label has the effect of light-angle color change.

[0125] Preferably, in the manufacturing method of the random texture anti-counterfeiting label in the second embodiment, the texture body 2 of Example 5 in the first embodiment is adopted. That is to say, the texture body of the texture material included in the random texture anti-counterfeiting label in this embodiment is the texture body 2 of Example 5 in the first embodiment. There is at least one inclination angle above the adhesive layer, and the overall visual color formed by observing the texture body 2 of a large number of texture materials at this inclination angle is visually distinguishable from the overall visual color formed by observing the texture body of a large number of texture materials in the vertical direction perpendicular to the adhesive layer above the adhesive layer. For the specific effect, see Example 5 in the first embodiment, which will not be elaborated here. When the texture body 2 of Example 5 in the first embodiment is adopted, the side end face of the texture body 2 should be observable. Preferably, the spacer 3 is made of a transparent material. Preferably, the spacer 3 is dissolved by the first solvent.

[0126] Of course, the random texture anti-counterfeiting label prepared in the second embodiment may also include a corresponding code, such as a two-dimensional code, as shown in Figure 3 and Figure 4 .

[0127] Example 4

[0128] This embodiment provides a random texture anti-counterfeiting label, which includes a carrier and a large number of texture materials densely and non-overlappingly distributed on the carrier. The texture materials are the texture materials described in the first embodiment, and the lower surface of the texture materials is in contact with the bearing surface of the carrier, as shown in Figures 2-5 .

[0129] In this way, the texture materials on the obtained random texture anti-counterfeiting label can ensure the dense and non-overlapping distribution of the texture materials on the carrier. Secondly, due to the existence of the spacer, there is a gap between the texture bodies of adjacent texture materials, making the visual color of the texture body more prominent, which is beneficial to the recognition and collection of the collector. In other words, the texture materials can be made smaller, and a larger number of texture fibers can be distributed per unit area, increasing the difficulty for counterfeiters to place them. At the same time, when the visual feature of the texture body is a three-dimensional visual feature, it further prevents imitation by printing, printing, engraving, and molding. For the beneficial effects of the random texture anti-counterfeiting label specifically using the texture materials, see the first embodiment, which will not be elaborated here.

[0130] Preferably, as shown in Figure 6 , the carrier 4 includes a material layer 5 and an adhesive layer 6. The texture materials are bonded to the adhesive layer 6, and the lower surface of the texture material 1 is bonded and fixed to the adhesive layer 6. In this embodiment, the material layer 5 and the adhesive layer 6 are prepared from different materials, but the material layer 5 and the adhesive layer 6 can also be of the same material. For example, one side of the material layer 5 is melted to form the adhesive layer 6.

[0131] Preferably, a layer of coating is covered on one side of the random texture anti-counterfeiting label where the texture material 1 is located. This coating covers the bearing surface of the carrier and the texture material 1 adhered thereto, so as to strengthen the adhesion of the texture material 1 on the bearing surface and prevent the texture material 1 from falling off the bearing surface.

[0132] Further preferably, the coating is a UV light-curing material layer or an AB glue layer.

[0133] Preferably, the random texture anti-counterfeiting label in this embodiment adopts the texture body 2 with optical angle color change in Example 4 of Embodiment 1. In this way, the obtained random texture anti-counterfeiting label has the effect of optical angle color change.

[0134] Preferably, the random texture anti-counterfeiting label in this embodiment adopts the texture body 2 in Example 5 of Embodiment 1. So that there is at least one inclination angle above the bearing surface, and the overall visual color formed by observing the texture body 2 of a large number of texture materials at this inclination angle is different from the overall visual color formed by observing the texture body 2 of a large number of texture materials in the vertical direction perpendicular to the bearing surface above the bearing surface, presenting a visually distinguishable color difference to the human eye. When the texture body 2 in Example 5 of Embodiment 1 is adopted, the side end face of the texture body 2 should be observable. Preferably, the spacer 3 is made of a transparent material. Preferably, the spacer 3 is dissolved by the first solvent. Since Example 5 of Embodiment 1 is adopted, corresponding beneficial technical effects are obtained.

[0135] Of course, the random texture anti-counterfeiting label in this embodiment may also include a corresponding code, such as a two-dimensional code, see Figure 3 and Figure 4 .

[0136] Example 5

[0137] This embodiment provides a random texture anti-counterfeiting system. Since the random texture anti-counterfeiting labels in Embodiment 3 and Embodiment 4 are adopted, the same beneficial technical effects are obtained.

[0138] Example 1

[0139] This example provides a random texture anti-counterfeiting system, including the random texture anti-counterfeiting labels in Embodiment 3 and Embodiment 4, and a storage acquisition module and a storage module connected to each other. Among them, the storage acquisition module is used to acquire the stored random texture distribution image information and / or the stored random texture distribution feature information of the random texture anti-counterfeiting label; the storage module stores the acquired stored random texture distribution image information and / or the stored random texture distribution feature information.

[0140] Since the random texture anti-counterfeiting label adopts the anti-counterfeiting labels of Embodiment 3 and Embodiment 4, the random texture anti-counterfeiting system thus obtains the same beneficial technical effects. For example, when the storage and acquisition module acquires the image information and / or feature information of the random texture anti-counterfeiting label, it can distinguish smaller texture materials, improving the resolution.

[0141] Example 2

[0142] The difference between this example and Example 1 is that the random texture anti-counterfeiting system further includes an identification and acquisition module for obtaining the image information of the random texture distribution to be identified and / or the feature information of the random texture distribution to be identified of the random texture anti-counterfeiting label to be identified.

[0143] By the same token, due to the adoption of the random texture anti-counterfeiting labels of Embodiment 3 and Embodiment 4, the identification and acquisition module can acquire smaller texture materials, which is equivalent to improving the resolution.

[0144] Example 3

[0145] Such as Figure 9 , the difference between this example and Example 2 is that the random texture anti-counterfeiting system further includes a comparison module. The comparison module is respectively connected to the storage module and the identification and acquisition module, and is used for comparing the image information of the random texture distribution to be identified and / or the feature information of the random texture distribution to be identified of the random texture anti-counterfeiting label to be identified acquired by the identification and acquisition module with the stored random texture distribution image information and / or the stored random texture distribution feature information pre-stored in the storage module. The comparison module will finally feedback the comparison result to the user.

[0146] In this example, the random texture anti-counterfeiting system in this example uses the comparison module to compare the anti-counterfeiting information pre-stored in the storage and acquisition module and the anti-counterfeiting information to be identified acquired by the identification and acquisition module to determine the authenticity. Since the texture bodies with anti-counterfeiting features in the adopted random texture anti-counterfeiting label are separated by the spacer portions, the interference caused by adjacent texture bodies to the acquisition and identification is avoided, and at the same time, the shielding of the side end faces with anti-counterfeiting features of adjacent texture bodies to each other is avoided. In this way, the size of the texture material can be further reduced and the distribution can be made more dense to improve the anti-counterfeiting performance.

[0147] In this embodiment, the storage and acquisition module can be a scanner or a camera.

[0148] In this embodiment, the identification and acquisition module can be a mobile phone with a photographing function.
