Abstract
Description
Technical Field
[0001] This application relates to the field of anti-counterfeiting technology, and further to a mesh hinged hinge and a booklet-style certificate. Background Technology
[0002] As is well known, anti-counterfeiting technology refers to measures taken to facilitate users in distinguishing between genuine and counterfeit products in order to achieve the purpose of anti-counterfeiting. It can accurately identify genuine and counterfeit products within a certain range and has the characteristics of being difficult to imitate and copy.
[0003] In recent years, with continuous technological advancements, traditional anti-counterfeiting methods (such as watermarks and laser holography) have been increasingly counterfeited. Currently, the manufacturing processes for anti-counterfeiting methods in related industries are complex and costly. Therefore, most anti-counterfeiting technologies on the market employ single technologies, resulting in limited effectiveness. However, with the expansion of application areas, the market demands increasingly higher anti-counterfeiting performance. For example, anti-counterfeiting methods used in passports, bank passbooks, and checkbooks must also possess properties such as lamination capability, sewing capability, flexibility, high durability, and tear resistance. Therefore, the inventors believe that developing an anti-counterfeiting product that integrates multiple anti-counterfeiting technologies, possesses excellent physical properties, and is cost-effective will have significant practical implications for the development of the anti-counterfeiting industry. Utility Model Content
[0004] The purpose of this application is to provide a mesh hinged loose-leaf document and a booklet-style document that integrates multiple anti-counterfeiting technologies and has excellent physical properties such as tear resistance, flexibility, and sewing capability. It is suitable for booklet-style documents, tickets, packaging and other fields, with a wide range of applications, low production cost and strong practicality.
[0005] The technical solution provided in this application is as follows:
[0006] On the one hand, this application provides a textured hinge hinge, comprising:
[0007] A fabric layer, wherein several reflective surfaces are hot-pressed at the intersection of warp and weft threads on the surface of the fabric layer to present a latent image window of a predetermined shape in a predetermined area on the surface of the fabric layer; a periodic grating is formed on the fabric layer corresponding to the latent image window to present a latent image pattern on the surface of the fabric layer.
[0008] A first surface layer and a second surface layer are respectively disposed on both sides of the fabric layer in the thickness direction to cover the fabric layer.
[0009] The mesh hinge hinge provided in this application features a fabric layer as the core layer. This mesh hinge hinge possesses excellent physical properties such as tear resistance, flexibility, sewing capability, lamination capability, and high durability. Furthermore, latent image windows are set at the intersections of warp and weft threads on the fabric layer surface, and corresponding periodic grating structures are molded onto these latent image windows. This integrates two anti-counterfeiting structures, causing specific areas on the surface of the mesh hinge hinge hinge to display latent image patterns of specific shapes. This effectively enriches the visual effect of the anti-counterfeiting pattern, enhancing its dynamism, interest, and aesthetics, thereby improving the anti-counterfeiting identification of the mesh hinge hinge hinge and ensuring its anti-counterfeiting capability. Therefore, it can be applied to anti-counterfeiting in passports, checkbooks, bank passbooks, and other booklet-type documents, tickets, and packaging, effectively expanding its applicability and enhancing its practicality. Simultaneously, its production method is simple, suitable for mass production, and has low cost, helping enterprises reduce costs and increase efficiency.
[0010] In some embodiments, the fabric layer has a plain weave mesh structure, and the first surface layer and the second surface layer are hot-pressed onto the surface of the fabric layer and connected through the texture gaps of the fabric layer.
[0011] The mesh hinge provided in this application utilizes a plain weave with numerous interlacing points, resulting in a flat, thin, and high-strength overall hinge that helps ensure its excellent physical properties and compatibility with passports, checkbooks, bank passbooks, and other document-type documents and tickets. Furthermore, by hot-pressing the first and second surface layers onto both sides of the fabric layer, the materials of the first and second surface layers interpenetrate and connect through the texture gaps of the fabric layer, enhancing the adhesion strength of the first and second surface layers to the fabric surface. This effectively improves the structural strength of the mesh hinge and extends its service life.
[0012] In some embodiments, the fabric layer is provided with through holes spaced evenly apart, and the first surface layer and the second surface layer are connected through the through holes.
[0013] The mesh hinge provided in this application has through holes in the fabric layer. In actual production, when the first and second surface layers are hot-pressed onto the fabric layer surface, excess material can be accommodated in the through holes. On the one hand, the materials of the first and second surface layers are connected to each other through the through holes, which helps to further improve the stability of their adhesion to the fabric layer surface. On the other hand, the excess material can be accommodated in the through holes, which helps to reduce the probability of bubbles and bulges on the surface of the finished mesh hinge, thereby improving its overall flatness.
[0014] In some embodiments, the material of the fabric layer located on the inner wall of the through hole is fused together to form a reinforcing ring;
[0015] And / or, the materials at the edges of the fabric layers fuse together to form a reinforcing edge.
[0016] The mesh hinge provided in this application, because the fabric layer is plain woven, fuses the material at the edge of the through hole when it is opened, and / or fuses the material at the cutting line when it is cut, helps to avoid the probability of the fabric layer coming loose at the through hole and / or edge, thereby further improving its structural strength and extending its service life.
[0017] In some embodiments, an ink layer is printed on the surface of the fabric layer to present preset graphic information on the surface of the fabric layer;
[0018] The latent pattern is formed on the surface of the ink layer.
[0019] In some embodiments, the ink layer includes an invisible anti-counterfeiting ink layer.
[0020] In some embodiments, the invisible anti-counterfeiting ink layer includes visible graphic areas.
[0021] And / or, the invisible anti-counterfeiting ink layer includes an invisible graphic area.
[0022] The mesh hinge provided in this application coats the fabric layer surface with invisible anti-counterfeiting ink to print visible / invisible graphic information. This allows specific areas on the surface of the mesh hinge hinge to display preset graphic effects, further enriching its visual appeal and enhancing its anti-counterfeiting capabilities. Simultaneously, since the invisible anti-counterfeiting ink has a temperature resistance coefficient of up to 200 degrees Celsius for 20 minutes, it helps ensure that the mesh hinge hinge maintains its anti-counterfeiting effect in high-temperature environments, guaranteeing the rigor of its manufacturing process and further extending its service life.
[0023] In some embodiments, a safety thread is woven into the fabric layer.
[0024] The mesh hinge provided in this application incorporates a security thread woven into the fabric layer, which helps to enhance the anti-counterfeiting effect of the fabric layer and thus effectively ensures the overall anti-counterfeiting capability of the mesh hinge.
[0025] In some embodiments, the security thread includes invisible anti-counterfeiting fluorescent fibers woven into the fabric layer using an encryption algorithm.
[0026] The mesh hinge provided in this application features an invisible anti-counterfeiting fluorescent fiber that emits fluorescence under ultraviolet light. The invisible anti-counterfeiting fluorescent fiber is woven into the fabric layer as a security thread, which has the characteristics of strong concealment and difficulty in counterfeiting. This helps to improve the anti-counterfeiting effect of the fabric layer and thus effectively ensures the overall anti-counterfeiting capability of the mesh hinge.
[0027] On the other hand, this application also provides a form of identification document, including any of the aforementioned mesh hinged loose-leaf pages, and further comprising:
[0028] The information layer is printed on the surfaces of the first and second surfaces that are opposite to each other.
[0029] The document provided in this application has excellent physical properties such as tear resistance, flexibility, and sewing capability of its fabric layer. In addition, a specific latent pattern of a specific shape is presented in a specific area on the surface of the mesh hinged flaps. This makes it easy to sew / hinge the flaps of the document, which is convenient to manufacture, inexpensive, not easy to break after folding, has a long service life, and has stable anti-counterfeiting capabilities, with good overall performance.
[0030] Compared with the prior art, the mesh hinge hinge and formwork document provided in this application have at least one of the following advantages:
[0031] 1. In this application, by setting a fabric layer as the central layer, a latent image grating is molded at the intersection of the warp and weft threads of the fabric layer, and a corresponding periodic grating structure is formed on the latent image grating. This gives the mesh hinge not only excellent physical properties such as tear resistance, flexibility, and sewing capability, but also good anti-counterfeiting performance. This makes it suitable for anti-counterfeiting in various fields such as passports, checkbooks, bank passbooks, and other booklet-type documents, tickets, and packaging, effectively expanding its applicability and enhancing its practicality. Furthermore, its manufacturing process is simple and convenient, suitable for mass production, and beneficial for enterprises to save energy and reduce costs.
[0032] 2. This application significantly improves the flatness and structural strength of the mesh hinge hinge by creating through holes in the fabric layer; at the same time, the material of the inner wall of the through hole is fused together to effectively prevent the fabric layer from unraveling, further improving the structural strength of the mesh hinge hinge. Moreover, the process is simple and easy to operate, which helps to further promote cost reduction and efficiency improvement for enterprises.
[0033] 3. In this application, by weaving invisible anti-counterfeiting fluorescent fibers into the fabric layer as a security thread, and printing visible and / or invisible graphic information on the surface of the fabric layer, and superimposing the graphic effect in the latent window, the anti-counterfeiting performance is improved while the visual effect of the anti-counterfeiting pattern is significantly enhanced, thereby effectively ensuring the security and aesthetics of the corresponding certificate, ticket, packaging product, etc. Attached Figure Description

[0051] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.
[0052] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."
[0053] As is well known, passports, bank passbooks, checkbooks, and other similar documents all have internal loose-leaf pages. In addition to having certain anti-counterfeiting features, these pages also need to be sewnable, laminateable, flexible and bend-resistant, highly durable, and tear-resistant. However, the anti-counterfeiting measures in these technologies mostly employ single anti-counterfeiting techniques, resulting in limited effectiveness and easy counterfeiting. Furthermore, their physical properties need improvement, leading to poor usability of these document types and documents, as well as high production difficulty and cost, thus requiring further improvement.
[0054] For this, please refer to the accompanying drawings in the instruction manual. Figures 1 to 12 In one embodiment, a mesh hinged hinge is provided, which integrates multiple anti-counterfeiting technologies and possesses excellent tear resistance, flexibility, and sewing properties. It can be widely used in various types of booklet documents, tickets, and packaging, such as passports, bank passbooks, checkbooks, bill books, or identity booklets, and is cost-effective. It includes a first surface layer 1, a fabric layer 2, and a second surface layer 3 arranged sequentially from top to bottom. The fabric layer 2 has several reflective surfaces 21 hot-pressed at the intersection of warp and weft threads to present a latent image window of a predetermined shape in a predetermined area on the surface of the fabric layer 2. A periodic grating is formed on the fabric layer 2 corresponding to the latent image window to present a latent image pattern 211 of a predetermined shape in the predetermined area on the surface of the fabric layer 2. The first surface layer 1 and the second surface layer 3 are respectively disposed on both sides of the fabric layer 2 in the thickness direction to cover the fabric layer 2.
[0055] In practical applications, a suitable material is selected to weave fabric layer 2, and then the surface of fabric layer 2 is heated and pressurized so that the warp and weft threads of fabric layer 2 only show a reflective surface 21 when viewed obliquely to the light, so as to form a latent image window of a preset shape; at the same time, a periodic grating is formed on fabric layer 2 at the position corresponding to the latent image window by means of engraving pattern embossing roller molding, so that a latent image pattern 211 of a preset shape is formed at the preset position on the surface of fabric layer 2.
[0056] In this manner, the mesh hinge hinge features a fabric layer 2 as its central layer, with latent image windows molded at the intersections of the warp and weft threads. These latent image windows are also shaped with corresponding periodic grating structures. This design gives the mesh hinge hinge excellent tear resistance, flexibility, and sewing capabilities, while also providing a specific latent image pattern 211 effect in specific areas. This significantly enhances its visual appeal and anti-counterfeiting effects. Furthermore, its production method is simple, suitable for large-scale industrial production, and has low production and usage costs. It can be used for anti-counterfeiting in various fields such as document cards, tickets, and packaging, making it widely applicable and highly practical.
[0057] In one embodiment, specifically based on the above embodiments. (Refer to...) Figures 1 to 12 Fabric layer 2 can be woven from single materials or blended materials such as polyester fiber, nylon filament, aramid filament, basalt fiber, and carbon fiber. This embodiment only uses polyester fiber, i.e., PET material, as an example for illustrating the use of fabric layer 2. (Refer to...) Figure 1 and Figure 9 In this embodiment, fabric layer 2 adopts a plain weave pattern, that is, fabric layer 2 has a plain mesh structure, which makes it thinner and flatter while ensuring the overall strength of fabric layer 2. Of course, in other embodiments of this application, the weave structure of fabric layer 2 is not limited to this. At the same time, in order to improve the anti-counterfeiting effect, a security thread can be woven into fabric layer 2; for example, invisible anti-counterfeiting fluorescent fiber is selected as the security thread. The invisible anti-counterfeiting fluorescent fiber emits fluorescence under ultraviolet light, which has the characteristics of strong concealment and difficulty in counterfeiting, thereby significantly improving the anti-counterfeiting level of fabric layer 2. Furthermore, in this embodiment, preferably, the security thread is woven into fabric layer 2 through an encryption algorithm to form a unique anti-counterfeiting code. The encoding rules can be as follows: Define colors as R, G, and B; define sequential numbers as 1, 2, and 3; combine these to form R1, R2, R3, G1, G2, G3, B1, B2, B3, R1G1B1, representing 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 respectively; and arbitrarily select a sequence of numbers from an infinite number of non-repeating irrational numbers as the encoding. Figure 7 As shown, the 100th to 110th digits of π, 5342117067, are used as the weaving code, and the security thread is woven into fabric layer 2.
[0058] In this embodiment, the first surface layer 1 and the second surface layer 3 are preferably made of PC material. However, in the embodiments of this application, depending on the application scenario, the first surface layer 1 and the second surface layer 3 can also be made of other different materials, such as PC, PVC, PET, PETG, BOPP, etc., commonly used in the industry. This embodiment does not impose specific limitations on this; it only uses the example of the first surface layer 1 and the second surface layer 3 being made of PC material for illustration. (Refer to...) Figure 1 and Figure 8 The first surface layer 1 and the second surface layer 3 are hot-pressed onto the surface of the fabric layer 2 and connected together through the texture gaps of the fabric layer 2.
[0059] Furthermore, refer to Figure 8 and Figure 9 Multiple through holes 22 are evenly spaced along the length of the fabric layer 2. The through holes 22 are used to accommodate excess PC material to reduce the probability of bubbles and bulges on the surface of the finished mesh hinge, and further improve its overall flatness. In addition, the excess material is accommodated in the through holes 22 and connects the first surface layer 1 and the second surface layer 3, which helps to improve the stability of the first surface layer 1 and the second surface layer 3 adhering to the surface of the fabric layer 2.
[0060] At the same time, refer to Figure 9 Since fabric layer 2 is plain woven, in this embodiment, the material at the inner wall of each through hole 22 of fabric layer 2 is fused together to form a reinforcing ring 23; of course, since fabric layer 2 is usually cut from a larger finished product to suit molding and other operations, therefore, referring to Figure 10 The materials at the edge of the fabric layer 2 also need to be fused together to form a reinforcing edge 24; in this way, the unraveling of threads at the through holes 22 and / or edges of the fabric layer 2 can be avoided as much as possible, thereby further improving its structural strength and extending its service life.
[0061] In actual production, high-temperature resistant and tear-resistant fiber materials such as polyester and aramid are selected and woven into a mesh structure using a plain weave. The finished mesh structure is then cut into strips suitable for molding dimensions. To ensure that the dividing lines are smooth, burr-free, and do not fray, thus guaranteeing the structural strength of fabric layer 2, it is preferable to first melt-press the dividing lines of the finished mesh structure into strips (edges) before cutting. For example, ultrasonic melting can be used at the dividing lines, followed by cold cutting. Of course, as long as the above effects can be guaranteed, hot melt cutting, ultrasonic cutting, or cold cutting can also be used for cutting. The embodiments of this application do not impose specific limitations on this. Then, an embossing roller with a periodic grating structure is used to form a latent pattern 211 on the mesh structure strips by heating and pressing. Of course, the periodic grating can also be a laser-induced periodic microstructure. In the embodiments of this application, the forming method of the periodic grating structure is not specifically limited. Subsequently, the fabric layer 2 is perforated using the aforementioned method, and the first surface layer 1 and the second surface layer 3 are hot-pressed onto its two sides respectively to produce the mesh hinge. The process is simple and inexpensive.
[0062] Of course, to further enhance the anti-counterfeiting capabilities of the mesh hinge hinge, refer to Figure 11 and Figure 12 Furthermore, an ink layer can be printed on the surface of the fabric layer 2 to superimpose corresponding preset graphic information on the surface of the fabric layer 2. In this embodiment, it is preferable that the latent image pattern 211 is formed on the surface of the ink layer. That is, in actual production, the graphic information layer is first printed on the surface of the fabric layer 2, and then the latent image pattern 211 is molded. In this preferred embodiment, invisible anti-counterfeiting ink is used to print graphic information, taking advantage of its high-temperature resistance (temperature resistance coefficient can reach 200 degrees Celsius for 20 minutes) to ensure the anti-counterfeiting capability of the mesh hinge hinge in high-temperature environments. That is, the ink layer includes an invisible anti-counterfeiting ink layer. In the embodiments of this application, invisible anti-counterfeiting ink can be used to print visible graphics, such as using an ultraviolet light-curing ink layer to print visible graphics, or invisible anti-counterfeiting ink can be used to print invisible graphics, such as using an ultraviolet fluorescent ink layer to print invisible graphics. Of course, it is preferable to use invisible anti-counterfeiting ink to print visible graphics areas and invisible graphics areas on the surface of the fabric layer 2, respectively, to further enhance the visual effect and anti-counterfeiting identification of the mesh hinge hinge. That is, the invisible anti-counterfeiting ink layer includes visible graphics areas and / or invisible graphics areas.
[0063] The implementation principle of this application embodiment is as follows: by superimposing fiber weaving, printing visible or invisible graphic information, and imprinting latent image patterns 211, etc., while improving the physical properties of the mesh hinge hinge, such as tear resistance, flexibility, sewing capability, lamination capability, and high durability, its anti-counterfeiting performance is significantly improved, making it difficult to be counterfeited and suitable for industrial mass production. It can be widely used in passports, checkbooks, bank passbooks and other booklet-type documents, bills and packaging, effectively expanding its application scope, enhancing its practicality, reducing enterprise cost input, and promoting cost reduction and efficiency improvement.
[0064] The technical solution of this application will be further described below, taking the application of the mesh hinged flap in a specific type of document as an example. In one embodiment, referring to... Figure 13 The document provides a type of identification document, including the mesh hinged loose-leaf described in any of the above embodiments, and also includes an information layer 110, which is configured as a colored ink layer and printed on the surfaces of the first surface layer 1 and the second surface layer 3 that are opposite to each other.
[0065] The mesh hinged loose-leaf, as one of the loose-leaf pages in the corresponding document 100, can be directly hinged to other loose-leaf pages on one side, and the corresponding information layer 110 is printed in the middle area of the loose-leaf page or near the other side edge; or, the information layer 110 is printed on the loose-leaf page near its two side edges respectively, and the hinge line between the loose-leaf pages is set in the middle of the loose-leaf page.
[0066] In addition, in order to reduce the production cost of the corresponding document 100, depending on the actual document production method, the hinge section of the loose-leaf can be set only as the fabric layer 2, that is, only the fiber mesh part is set in the hinge section of the loose-leaf, while the ink layer with anti-counterfeiting function, latent image pattern 211, etc. are set in the information layer 110 coverage area of the loose-leaf.
[0067] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
