[0040] This utility model proposes a sticker frame 100 for attaching and displaying stickers.

[0041] In this embodiment of the utility model, please refer to Figures 1 to 8The sticker frame 100 includes a supporting substrate 10 and a first display element 20. Both the supporting substrate 10 and the first display element 20 are made of cardboard. The supporting substrate 10 includes a joining area 111 and a sticker adhesion area 112. The joining area 111 surrounds the sticker adhesion area 112. The sticker adhesion area 112 is provided with a release layer 113. The roughness of the release layer 113 is less than that of the joining area 111. The release layer 113 is used to removably adhere the sticker. The first display element 20 is foldably connected to one end of the joining area 111 and is fixedly connected to the joining area 111. The first display element 20 has a first viewing window 21 corresponding to the sticker adhesion area 112, so that when the first display element 20 covers the supporting substrate 10, the release layer 113 is exposed in the first viewing window 21.

[0042] In this embodiment, the sticker frame 100 includes a supporting substrate 10 and a first display element 20. The supporting substrate 10 is preferably made of cardboard to ensure good rigidity and stability of the frame as a whole. The supporting substrate 10 includes a joining area 111 and a sticker adhesion area 112. The joining area 111 surrounds the sticker adhesion area 112 to form a frame. The joining area 111 and the sticker adhesion area 112 are located on the wall surface of the supporting substrate 10 near the first display element 20. The sticker adhesion area 112 is located in the middle portion surrounded by the joining area 111. The sticker adhesion area 112 is provided with a release layer 113. The release layer 113 can be the supporting substrate 10 itself or a layer covering the supporting substrate 10; there is no limitation here. The surface of the release layer 113 is flattened or coated to make its surface roughness lower than that of the joining area 111, thereby forming a relatively smooth surface. The smooth surface facilitates removable adhesion and peeling of the sticker. Even if the sticker is misaligned during application, the user can easily peel it off and re-apply it, avoiding adhesive residue or sticker damage. In some embodiments, the surface of the release layer 113 can also be treated by covering it with a transparent film, a smooth coating, or applying an anti-adhesive agent to further enhance its reusability. The coating material can be environmentally friendly materials such as polyester film, polypropylene film, or water-based varnish.

[0043] The first display piece 20 is connected to one end of the joining area 111 via a fold line or indentation, allowing it to be folded around the fold line. The first display piece 20 is also made of cardboard and is fixedly connected to the joining area 111, such as by adhesive or snap-fit ​​structures. In some embodiments, the supporting substrate 10 and the first display piece 20 can be integrally die-cut and folded and assembled via pre-set fold lines, or they can be assembled from separate structures to facilitate mass production and packaging for transportation.

[0044] The first display piece 20 has a first viewing window 21 corresponding to the sticker adhesion area 112. This viewing window can be rectangular, circular, oval, or other decorative shapes to meet different aesthetic needs of users. After the first display piece 20 is folded and connected and fixed to the joint area 111, the sticker pattern attached to the release layer 113 can be displayed through the first viewing window 21.

[0045] In use, the user first unfolds the first display piece 20 relative to the supporting substrate 10, then attaches the sticker to the release layer 113 in the sticker adhesion area 112, and finally covers the supporting substrate 10 with the first display piece 20, so that the sticker is exposed in the viewing window.

[0046] This utility model's sticker photo frame 100 includes a supporting substrate 10 and a first display element 20. Both the supporting substrate 10 and the first display element 20 are made of cardboard, providing both support rigidity and foldability. Furthermore, the supporting substrate 10 has a joining area 111 and a sticker adhesion area 112, with the joining area 111 surrounding the sticker adhesion area 112 to form a border. The sticker adhesion area 112 has a release layer 113, the roughness of which is less than that of the joining area 111. Compared to solutions where both areas have the same roughness, this utility model allows for removable adhesion and reuse of the sticker on the release layer 113. If the user makes a mistake during application, the sticker can be easily peeled off and readjusted, preventing adhesive residue or sticker damage, thus extending the sticker's lifespan. Simultaneously, the first display element 20 has a viewing window to display the sticker content and can be designed with different shapes and styles as needed, enhancing the frame's decorative appeal.

[0047] In one embodiment, a release film is applied to the support substrate 10 corresponding to the sticker adhesion area 112 to form a release layer 113, the release film protruding from the bonding area 111 along the thickness direction of the support substrate 10.

[0048] In this embodiment, a release film is applied to the support substrate 10 corresponding to the sticker adhesion area 112 to form a release layer 113, meaning that the release layer 113 and the support substrate 10 are separate layers. The release film is a thin film layer with strong peelability, such as silicone paper, polyester film, polypropylene film, or synthetic paper with a release treatment surface. The release layer 113 protrudes from the bonding area 111 along the thickness direction of the support substrate 10, so that the sticker adhesion area 112 forms a certain step or protrusion structure relative to the bonding area 111. This facilitates the user's intuitive positioning of the sticker adhesion area 112 during actual operation, and also makes it easier for the user to pick up the sticker from the edge of the release layer 113 when peeling off the sticker, improving the convenience of sticker removal and re-application. Furthermore, the release layer 113 can be firmly connected to the sticker adhesion area 112 by methods such as screen printing UV, lamination, hot pressing, or adhesive bonding, thereby ensuring that it is not easy to lift or fall off during repeated application and removal.

[0049] Specifically, the release layer 113 is made of a low surface energy material, such as silicone paper, polytetrafluoroethylene film, polyester film, or release-treated synthetic paper. Low surface energy materials can significantly reduce the adhesion between the sticker adhesive and the frame, thereby improving the sticker's reusability and ease of removal.

[0050] Specifically, the release layer 113 is screen-printed onto the support substrate 10. Screen printing allows the release coating to be uniformly and firmly covered on the sticker adhesion area 112, offering advantages such as high processing efficiency, low cost, and uniform processing over a large area. The release layer 113 formed by the screen printing process has a uniform thickness and strong adhesion, making it less prone to detachment during repeated application and peeling. Simultaneously, it maintains good low surface energy characteristics, ensuring the reusability of the sticker.

[0051] In one embodiment, the sticker adhesion area 112 includes sub-areas 1121, each sub-area 1121 is provided with a release layer 113, and adjacent sub-areas 1121 are spaced apart; the first viewing window 21 includes multiple sub-windows 211, each sub-window 211 is provided in a corresponding manner to the adhesion area, and a blocking border is provided between adjacent sub-windows 211.

[0052] In this embodiment, the sticker adhesion area 112 includes several sub-areas 1121, each of which is provided with a release layer 113. Adjacent sub-areas 1121 are spaced apart. The sub-areas 1121 can be rectangular, square, circular, or other geometric shapes, and the spaced arrangement creates a certain gap between adjacent sub-areas 1121, allowing users to display multiple stickers on the same frame while avoiding interference between different stickers. The surface of each sub-area 1121 is a low surface energy release layer 113, thereby ensuring that the stickers in each area can be removably applied and peeled off.

[0053] Accordingly, the first visible window 21 includes multiple sub-windows 211, and each of the multiple sub-regions 1121 in the sticker adhesion area 112 is set to correspond one-to-one. When multiple stickers are pasted onto each sub-region 1121, their content can be displayed through the corresponding sub-window 211.

[0054] A partition frame is provided between two adjacent sub-windows 211. The partition frame is formed by the cardboard portion of the first display element 20 and can be a straight or curved strip structure. It is used to separate multiple sub-windows 211, thereby creating a display format similar to a multi-pane picture frame in terms of visual effect. The partition frame not only enhances the overall neatness of the appearance but also prevents different sticker patterns from interfering with each other, thus improving the aesthetics of the picture frame.

[0055] Furthermore, the inner periphery of the sub-window 211 is located inside the outer periphery of the sub-region 1121. In other words, the opening range of each sub-window 211 is slightly smaller than the boundary range of the corresponding sub-region 1121, thus creating a shading margin between the periphery of the sub-window 211 and the edge of the sub-region 1121. The shading margin can be set according to actual needs, for example, from 0.2mm to 2mm, to ensure error tolerance without affecting the overall appearance of the window. Thus, even if the user slightly misaligns or deviates in position when pasting the sticker onto the sub-region 1121, the edge of the sticker is still covered by the shading border due to the small opening size of the sub-window 211. When viewed from the window direction, the unevenness of the sticker edge will not be visible, achieving a complete and neat display effect.

[0056] In other embodiments, refer to Figures 5 to 8 The sticker frame 100 also includes a second display element 50, which is foldably connected to the end of the support substrate 10 or the first display element 20 so that the second display element 50 can cover the side of the first display element 20 away from the support substrate 10. The second display element 50 has a second viewing window 51 corresponding to the sticker adhesion area 112. The area of ​​the second viewing window 51 is larger than the area of ​​the first viewing window 21 so that when the second display element 50 covers the first display element 20, the first viewing window 21 is exposed in the second viewing window 51.

[0057] In this embodiment, the sticker frame 100 also includes a second display element 50. The second display element 50 is foldably connected to the end of the supporting substrate 10 and can cover the side of the first display element 20 opposite to the supporting substrate 10. The second display element 50 can be connected to the supporting substrate 10 by fold lines or indentations, facilitating unfolding and folding. The connection ends of the supporting substrate 10 and the first display element 20, as well as the connection ends of the supporting substrate 10 and the second display element 50, can be the same or different, and are not limited here. When the connection ends are the same, the second display element 50 is simultaneously connected to the first display element 20; when the connection ends are different, the second display element 50 and the first display element 20 are located adjacent to or opposite to the supporting substrate 10, respectively. The second display element 50 can also be connected to the end of the first display element 20, as long as the second display element 50 can cover the first display element 20.

[0058] The second display piece 50 has a second viewing window 51 corresponding to the sticker adhesion area 112. The second viewing window 51 can be rectangular, circular, elliptical, or other decorative shapes according to actual design needs, and is not limited here. The area of ​​the second viewing window 51 is larger than the area of ​​the first viewing window 21. When the second display piece 50 covers the first display piece 20, the first viewing window 21 can be exposed within the second viewing window 51, thereby achieving a layered display effect. In other words, the second viewing window 51 can visually accommodate multiple sub-windows 211 in the first viewing window 21, allowing the user to see multiple sticker sub-windows 211 on the first display piece 20 simultaneously, while maintaining overall visual unity and forming a three-dimensional, layered display effect.

[0059] In one embodiment, the first display component 20 includes a first connecting portion 22 and a second connecting portion 23. The first connecting portion 22 and the second connecting portion 23 are respectively disposed at opposite ends of the sticker adhesion area 112. The first connecting portion 22 is disposed at one end of the first display component 20 that is rotatably connected to the supporting substrate 10. The second connecting portion 23 is disposed at the free end of the first display component 20, and the area of ​​the second connecting portion 23 is larger than the area of ​​the first connecting portion 22.

[0060] In this embodiment, the first display component 20 includes a first connecting portion 22 and a second connecting portion 23. The first connecting portion 22 and the second connecting portion 23 are respectively disposed at opposite ends of the sticker adhesion area 112. The first connecting portion 22 is disposed at one end of the first display component 20 that is rotatably connected to the supporting substrate 10, and is used to achieve a fixed connection between the first display component 20 and the joining area 111.

[0061] The second connecting part 23 is located at the free end of the first display component 20, and its area is larger than that of the first connecting part 22. By increasing the area of ​​the second connecting part 23, not only can the overall stability of the first display component 20 be enhanced, but it also gives it additional functionality. For example, the second connecting part 23 can be clamped by a desktop clip, making it easier for users to fix the sticker frame 100 to a stand, display board, or other display tools to adapt to different display scenarios. Secondly, the surface of the second connecting part 23 can also serve as a writing area, where users can write annotations, messages, or signatures, thereby enhancing the interactivity and personalized user experience of the frame. This writing area can use a regular paper surface or be coated with a film to facilitate erasing and reuse.

[0062] In one embodiment, reference is made to Figure 2 and Figure 4 The supporting substrate 10 includes an inner layer 11 and an outer layer 12 that are interconnected. The inner layer 11 forms the inner wall surface of the supporting substrate 10. The bonding area 111 and the sticker adhesion area 112 are disposed on the inner layer 11. The release layer 113 is covered by the inner layer. The outer layer 12 forms the outer wall surface of the supporting substrate 10. The first display component 20 includes a first layer 24 and a second layer 25 that are interconnected. The first layer 24 forms the inner wall surface of the first display component 20. The second layer 25 forms the outer wall surface of the first display component 20. The inner layer 11 and the first layer 24 are integrally formed and can be folded and connected to each other. The outer layer 12 and the second layer 25 can be separated.

[0063] In this embodiment, the supporting substrate 10 includes an inner layer 11 and an outer layer 12 connected to each other. The inner layer 11 forms the inner wall surface of the supporting substrate 10, and the outer layer 12 forms the outer wall surface of the supporting substrate 10. The inner layer 11 and the outer layer 12 can be made by double-layer cardboard lamination or composite process. The inner layer 11 is mainly used to support the sticker adhesion area 112, while the outer layer 12 is used to provide decorative effect and overall strength. Correspondingly, the first display element 20 includes a first layer 24 and a second layer 25 connected to each other, wherein the first layer 24 forms the inner wall surface of the first display element 20, and the second layer 25 forms the outer wall surface of the first display element 20.

[0064] In this design, the inner layer 11 is integrally formed with the first layer 24 to ensure a foldable connection between the supporting substrate 10 and the first display component 20. The outer layer 12 and the second layer 25 are separable, allowing the upper edge of the first display component 20 to form a clear straight boundary, visually creating a sharp and complete edge effect, making the first display component 20 appear as a complete independent component. In contrast, if the outer layer 12 and the second layer 25 were integrally formed, a naturally transitioning arc structure would be formed at the connection point, weakening the sharpness of the edge and resulting in a more rounded overall visual effect.

[0065] In one embodiment, reference is made to Figure 3The outer layer 12 and the second layer 25 include a microporous ink layer 30, and / or the roughness of the inner layer 11 is less than that of the outer layer 12, and the roughness of the first layer 24 is less than that of the second layer 25.

[0066] In this embodiment, the outer layer 12 and the second layer 25 include a microporous ink-retaining layer 30. The microporous ink-retaining layer 30 enhances the ink's fixation ability, allowing the ink to better embed itself in the microporous structure, thereby improving the ink's adhesion and abrasion resistance, and preventing blurring / spreading of the print after finger contact or paper friction. Manufacturers can print on the microporous ink-retaining layer 30, and users can write or draw on it. For example, after printing a design on the microporous ink-retaining layer 30, users can write annotations or fill in colors on stickers; or a design can be printed on the microporous ink-retaining layer 30 with a lighter ink color, and users can trace the outline of the design; or only a portion of the design can be printed on the microporous ink-retaining layer 30, allowing users to further create based on it. The design can be text, cartoon characters, animals, or fruits, etc., and is not limited thereto.

[0067] The roughness of the inner layer 11 of the supporting substrate 10 is less than that of the outer layer 12, and the roughness of the first layer 24 is less than that of the second layer 25. Preferably, the inner layer 11 and the first layer 24 can be made by lamination, coating with varnish or other low-roughness treatments, thereby making it suitable for the sticker to be removable and reusable on its surface. This allows the user to remove the sticker if it is accidentally applied to the adhesive area 111 during the application process and then apply it to the correct sticker adhesion area 112. Furthermore, the surface roughness of the release layer 113 is less than that of the inner layer 11, making it easier for the user to peel off and readjust the sticker if it is misplaced or misaligned within the sticker adhesion area 112, thus improving the error tolerance of the sticker application process.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
