Abstract

In the field of sticker technology, we provide three-dimensional stickers. [Solution] The sticker comprises a protective layer 1, a filling layer 2, and a flat bottom layer 3. The protective layer is made of a transparent material, and a housing cavity 11 for housing the filling layer is formed on the surface of the protective layer facing the flat bottom layer. The surface of the protective layer near the flat bottom layer is flush with the outer edge of the housing cavity of the protective layer, and the outer edge of the housing cavity of the protective layer is fixedly connected to the flat bottom layer. The pattern can be formed on the filling layer, the flat bottom layer, or a surface near the flat bottom layer of the protective layer, and the pattern does not need to be formed on a surface away from the flat bottom layer of the protective layer. As a result, the surface of the sticker becomes smooth, the pattern is protected by the protective layer, and it is not damaged by friction due to external forces, thus avoiding the problem of the pattern layer of conventional three-dimensional stickers being exposed and easily worn.

Description

Technical Field

[0007] ,

[0001] This application relates to the field of stickers, and particularly to three-dimensional stickers.

Background Art

[0002] A sticker is a decorative or functional label, which is based on paper, plastic, fabric or other materials, with an adhesive substance coated on the back surface, and is used for pasting on the surfaces of various objects.

[0003] There are three-dimensional stickers with higher aesthetics in the market. However, in many of the patterned layers of the three-dimensional stickers in the market, they are attached to the surface of the sticker. As time passes, the pattern layer is scraped off, affecting the aesthetics of the sticker.

Summary of the Invention

[0004] This application provides a three-dimensional sticker in order to improve the aesthetics and durability of the sticker.

[0005] The three-dimensional sticker provided in this application adopts the following technical solution.

[0006] A three-dimensional sticker including a protective layer, a filling layer, and a flat bottom layer, wherein the protective layer adopts a transparent material, and a receiving cavity for accommodating the filling layer is formed on the surface of the protective layer facing the flat bottom layer, the surface of the protective layer close to the flat bottom layer is flush with the outer edge of the receiving cavity of the protective layer, and the outer edge of the receiving cavity of the protective layer is fixedly connected to the flat bottom layer.

[0007] By adopting the above technical proposal and designing a three-dimensional sticker structure including a protective layer, a filling layer, and a flat bottom layer, the filling layer is housed within the containment cavity formed by the protective layer. After aligning the surface of the protective layer near the flat bottom layer with the outer edge of the containment cavity, the filling layer is fixedly connected to the flat bottom layer, thereby completely enclosing the filling layer between the protective layer and the flat bottom layer. With this design, the pattern can be formed on the surface of the filling layer or the surface of the protective layer near the flat bottom layer, and the pattern does not need to be formed on a surface far from the flat bottom layer of the protective layer. As a result, the surface of the sticker becomes smooth, the pattern is protected by the protective layer, and it is not damaged by friction from external forces. At the same time, the three-dimensional structure of the filling layer enhances the visual three-dimensionality, improving the overall durability and aesthetics of the sticker, and avoiding the problem of the pattern layer of conventional three-dimensional stickers being exposed and easily worn.

[0008] Optionally, the filling layer is made of a transparent material, and a pattern is formed on its surface near the protective layer of the flat bottom layer.

[0009] The transparent filler layer allows the pattern on the flat base layer to be clearly visible through the filler and protective layers, while the three-dimensional structure of the filler layer gives the pattern a visual sense of depth and dimension. This design not only protects the pattern from being scratched or worn away, but the combination of material and structure also enhances the decorative and visual appeal of the sticker. Compared to forming the pattern on an uneven filler surface, the pattern is formed on the protective layer, reducing the difficulty of pattern processing.

[0010] Optionally, a pattern is formed on the surface of the protective layer near the flat bottom layer.

[0011] By adopting the above technical proposal, patterns can be simultaneously present between or on the protective layer and the flat base layer. Combining the superposition of multiple patterns with the three-dimensional effect of the filling layer further enhances the visual layering and artistic expressiveness of the sticker, improving the freedom and aesthetic appeal of sticker decoration.

[0012] The protective layer may optionally be made of PVC material.

[0013] PVC possesses good transparency, flexibility, and abrasion resistance, effectively protecting the internal filling layer and pattern from abrasion and environmental erosion. Furthermore, its ease of processing and molding is advantageous for the precise fabrication of the containment cavity, improving the overall durability and production efficiency of the stickers.

[0014] The filling layer may optionally be made of epoxy resin material.

[0015] Epoxy resins possess high transparency, good curing properties, and deformation stability, allowing them to form durable and vivid three-dimensional structures. They are resistant to yellowing and shrinkage, ensuring that stickers maintain their original three-dimensional effect and visual quality even after prolonged use.

[0016] The flat bottom layer is optionally made of PET material.

[0017] PET possesses high strength, tear resistance, and a smooth surface, making it suitable for printing intricate patterns. It can firmly bond with protective layers, increasing the overall structural strength of stickers and making them more suitable for various application surfaces and environmental conditions.

[0018] Optionally, the protective layer and the flat bottom layer are welded together by high-frequency hot pressure.

[0019] The protective layer and the flat bottom layer are permanently connected using high-frequency hot-pressure welding. This process ensures a strong seal between the two layers, preventing the filling layer from becoming damp or falling off. Furthermore, the welded area is flat and aesthetically pleasing, there are no adhesive residue issues, and the durability and aesthetic integrity of the sticker are improved.

[0020] Based on the above, this application includes at least one of the following beneficial technical effects.

[0021] 1. With a transparent filling layer, the pattern on the flat bottom layer can be clearly seen through the filling layer and the protective layer. At the same time, the three-dimensional structure of the filling layer gives the pattern a visual sense of hierarchy and three-dimensionality, protecting the pattern from being easily scraped or worn. Moreover, the combination of materials and structure improves the decorative and visual charm of the sticker, and reduces the processing difficulty of the pattern.

[0022] 2. The pattern can exist simultaneously between or on the protective layer and the flat bottom layer. By combining the overlay of multiple layers of patterns and the three-dimensional effect of the filling layer, the visual hierarchy and artistic expressiveness of the sticker are further enriched, improving the freedom of decoration and aesthetic appearance of the sticker.

Modes for Carrying Out the Invention

[0024] Hereinafter, in accordance with Figures 1 to 3, the present application will be further described.

[0025] In an embodiment of the present application, a three-dimensional sticker is disclosed. Referring to FIGS. 1 and 2, the three-dimensional sticker includes a protective layer 1, a filling layer 2, and a flat bottom layer 3. The protective layer 1 employs a transparent material, and on the surface facing the flat bottom layer 3, a receiving cavity 11 for accommodating the filling layer 2 is formed, and this surface is flush with the outer edge of the receiving cavity 11. By fixedly connecting the outer edge of the receiving cavity 11 to the flat bottom layer 3, the filling layer 2 is completely enclosed between the protective layer 1 and the flat bottom layer 3, protected so that the pattern is not damaged by rubbing with an external force, and at the same time, the three-dimensional aesthetic property of the sticker is improved. This is because as long as the pattern is formed on the surface close to the flat bottom layer 3 of the filling layer 2 or the protective layer 1 and not on the surface far from the flat bottom layer 3 of the protective layer 1, the surface of the sticker will be smooth, the pattern will be protected by the protective layer 1, and also, due to the three-dimensional structure of the filling layer 2, the visual three-dimensional sense is enhanced.

[0026] Referring to FIG. 2, due to the transparent material of the protective layer 1, the internal pattern can be clearly seen. The protective layer 1 in this embodiment employs a PVC material. PVC has good transparency, flexibility, and wear resistance, and can effectively protect the internal filling layer 2 and pattern from rubbing and environmental erosion. At the same time, its characteristic of being easy to process and form is advantageous for the precise production of the receiving cavity 11.

[0027] In other embodiments, the protective layer 1 can also use other transparent plastic materials such as PETG materials, and this material also has good transparency and processing performance.

[0028] Referring to FIG. 2, the protective layer 1 is formed by mold vacuum forming, and a receiving cavity 11 is formed on the surface close to the flat bottom layer 3 of the protective layer 1. In other embodiments, the protective layer 1 can also be formed by injection molding.

[0029] Referring to Figures 1 and 2, the shape and size of the containment cavity 11 are determined as needed. In this embodiment, the shape of the protective layer 1 and the stickers on the containment cavity 11 is a squid, while in other embodiments, the shape of the protective layer 1 and the containment cavity 11 may be other animals or plants or any shape.

[0030] Referring to Figure 1, a pattern (not shown) can be formed on the surface of the protective layer 1 near the flat bottom layer 3. The pattern can be formed on the surface of the protective layer 1 near the flat bottom layer 3 by processes such as printing, and the types of patterns can be similarly diverse.

[0031] Referring to Figure 2, the filling layer 2 has a three-dimensional structure and is made of a transparent material. In this embodiment, the filling layer 2 is made of epoxy resin, which has high transparency, good curability and deformation stability, and can form a persistent and clear three-dimensional structure. It is resistant to yellowing and shrinkage, so the original three-dimensional effect and visual quality are ensured even after the sticker has been used for a long period of time. In this application, the filling layer 2 is formed by dropping epoxy resin into the containment cavity 11 and then curing and molding it.

[0032] In other embodiments, the filling layer 2 may be made of an organic glass material, which also has high transparency and good hardness.

[0033] In other embodiments, the filling layer 2 can have color. In other embodiments, a pattern can be formed on the surface of the filling layer 2 by printing, and the types of patterns can be similarly diverse.

[0034] Referring to Figures 1 and 2, the flat bottom layer 3 completely covers the filling layer 2. The flat bottom layer 3 is made of a transparent material. In this embodiment, the flat bottom layer 3 is made of PET material, which has high strength, is tear-resistant, and has a smooth surface, making it suitable for printing fine patterns, and it can bond firmly with the protective layer 1, increasing the overall structural strength of the sticker and making it more suitable for various application surfaces and environmental conditions. In other embodiments, the flat bottom layer 3 can be made of other plastic film materials.

[0035] Referring to Figure 2, a pattern (not shown) can be formed on the surface of the flat bottom layer 3 near the protective layer 1, and the types of patterns can also be diverse, and these patterns can be printed on the flat bottom layer 3 by processes such as printing.

[0036] Referring to Figure 2, the outer edge of the housing cavity 11 of the protective layer 1 is fixedly connected to the flat bottom layer 3 by high-frequency hot-pressure welding. High-frequency hot-pressure welding enables a strong seal between the two layers, preventing the filling layer 2 from becoming damp or falling off. Furthermore, the welded area is flat and aesthetically pleasing, there are no adhesive residue issues, and the durability and aesthetic integrity of the sticker are improved. During the welding process, the heat generated by the high-frequency current melts and fuses the contact area between the protective layer 1 and the flat bottom layer 3, forming a strong connection.

[0037] Referring to Figure 3, the flat bottom layer 3 is covered with an adhesive layer 4 on the surface away from the protective layer 1, and since the material of the adhesive layer 4 is an adhesive, a sticker can be attached to the surface of an object.

[0038] The manufacturing process for the three-dimensional sticker of the embodiment of the present invention is as follows: First, a pattern is printed on a transparent PVC film (printing is not necessary if there is no pattern), then the transparent PVC film is vacuum-formed to form a protective layer 1 with a housing cavity 11, epoxy resin is dropped into the housing cavity 11 and cured to form a filling layer 2, further, a pattern is printed on a transparent PET film (printing is not necessary if there is no pattern) to form a flat bottom layer 3, and finally, the protective layer 1 and the flat bottom layer 3 are fixed by high-frequency hot-pressure welding, enclosing and sealing the filling layer 2, and an adhesive is applied to the surface of the flat bottom layer 3 away from the protective layer 1 to form an adhesive layer 4.

[0039] All of the above are preferred embodiments of the present application and do not limit the scope of protection thereunder; therefore, all equivalent modifications made based on the structure, shape, and principle of the present application should be included within the scope of protection.
