Description

Technical Field

[0001] This invention belongs to the field of packaging technology, and specifically relates to a protective film and electronic products. Background Technology

[0002] In industrial production and commodity circulation, products are highly susceptible to surface damage due to friction, collision, contamination, and other factors during warehousing, transportation, and handling, affecting their appearance quality and commercial value. Therefore, packaging protective films are widely used as a crucial surface protection material.

[0003] In related technologies, protective films are mostly sheet-like. However, since the products are three-dimensional, packaging products with protective films requires multiple folds, handling of wrinkles, and pasting of the packaged protective film. This results in low automation efficiency and seriously affects the production efficiency of electronic products.

[0004] Therefore, in view of the above shortcomings, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a protective film that at least partially solves the problems in the prior art.

[0006] The first aspect of the present invention provides a protective film, the protective film including a central area and a plurality of wing plates connected around the central area and arranged radially, the plurality of wing plates being folded and connected to one side to form a protective box with the central area, the inner cavity of the protective box being used for packaging products.

[0007] The protective film provided by this invention may also have the following additional technical features: In some specific embodiments of the present invention, the protective film is made of biodegradable sulfuric acid paper.

[0008] In some specific embodiments of the present invention, the number of wing plates is four.

[0009] In some specific embodiments of the present invention, two wing plates arranged opposite each other form a group, and the wing plates in each group are bonded together in pairs.

[0010] In some specific embodiments of the present invention, one of the wing plates in each group is provided with double-sided adhesive, and the two wing plates are bonded together by the double-sided adhesive.

[0011] In some specific embodiments of the present invention, each of the wing plates is provided with a first crease and a second crease spaced apart along the radial divergence direction, and the wing plate is folded along the first crease and the second crease.

[0012] In some specific embodiments of the present invention, the polygon formed by multiple first creases and the polygon formed by multiple second creases are coaxially arranged.

[0013] In some specific embodiments of the present invention, the distance between the first crease and the second crease is approximately the same as the thickness of the product to be packaged.

[0014] In some specific embodiments of the present invention, the free end of the wing plate is formed with a rounded corner, and the connection between the wing plate and the central area is formed as an arc.

[0015] A second aspect of the present invention also provides an electronic product, including a packaging box and the protective film described in any one of the above.

[0016] The protective film provided by this invention includes a central area and multiple wing plates connected to the outer periphery of the central area and radiating radially. In its formed state, it is flat. When packaging is required, the multiple wing plates can be folded towards the central axis of the central area and connected to form a protective box with the central area as the bottom wall and the wing plates as the side and top walls. The inner cavity of this protective box can be used to package products. Because the protective film is flat, it is easier for automated equipment to grasp during packaging. Furthermore, since the wing plates in the protective box are only connected at both ends (one end connected to the central area and the other end connected to each other), wrinkles are less likely to form during packaging, thus simplifying the packaging process and making it suitable for automated equipment, thereby greatly improving packaging efficiency and increasing the automation rate of production.

[0020] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0021] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0022] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0023] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0024] Reference Figures 1-4 The first aspect of the present invention provides a protective film 100, the protective film 100 including a central region 11 and a plurality of wing plates 12 connected around the central region 11 and arranged radially. The plurality of wing plates 12 are folded to one side to form a protective box with the central region 11, and the inner cavity of the protective box can be used to package products.

[0025] The protective film 100 provided in this embodiment includes a central area 11 and a plurality of wing plates 12 connected to the outer periphery of the central area 11 and arranged radially. In its formed state, the protective film 100 is generally flat. When packaging is required, the plurality of wing plates 12 can be folded and connected towards the central axis of the central area 11 to form a protective box with the central area 11 as the bottom wall and the wing plates 12 as the side walls and top wall. The inner cavity of the protective box can be used to package products. Because the protective film 100 is formed into a flat state, it is easier for automated equipment to grasp during packaging. At the same time, since the wing plates 12 in the protective box are only connected at both ends, that is, one end is connected to the central area and the other end is connected to each other, while other areas are not connected, wrinkles are less likely to form during the packaging process. This simplifies the packaging steps and makes it suitable for automated equipment, thereby greatly improving packaging efficiency and increasing the automation rate of production.

[0026] In some embodiments, the protective film 100 is made of biodegradable sulfuric acid paper. This reduces the environmental impact of the protective film 100, making it environmentally friendly.

[0027] In some embodiments, the number of wing plates 12 is four. Reducing the number of wing plates 12 can help to further simplify the packaging process, thereby further improving packaging efficiency.

[0028] Since there are four wing plates 12, the packaging box formed by the protective film 100 is a cuboid structure.

[0029] Of course, in other embodiments, the number of wing plates 12 can also be 3, 5, 6, 8, etc., which can be set according to the shape of the product to be packaged, and is not limited here.

[0030] In some embodiments, two opposing wing plates 12 are grouped together, and each pair of wing plates 12 in each group is bonded together. Thus, only two bonding operations are required to form the protective box, further simplifying the packaging process and improving packaging efficiency.

[0031] Of course, in other embodiments, any wing plate 12 can be bonded to adjacent wing plates 12 in a clockwise or counterclockwise direction to achieve the connection of wing plates 12. The specific choice can be made according to actual needs and is not limited here.

[0032] It should be noted that the wing plates can also be connected by snap-fit, for example, by setting mutually compatible cut lines and snap-fitting them together.

[0033] In some embodiments, one of the wing plates 12 in each group is provided with double-sided adhesive 13, and the two wing plates 12 are bonded together by the double-sided adhesive 13. The double-sided adhesive 13 is convenient to use and simple to operate, which can further simplify the packaging steps and improve packaging efficiency.

[0034] In some embodiments, each wing plate 12 is provided with a first crease 14 and a second crease 15 spaced apart along the radial divergence direction, and the wing plate 12 is folded along the first crease 14 and the second crease 15.

[0035] Specifically, the first crease 14 and the second crease 15 are embossing lines formed by pre-pressing. In this embodiment, by forming two creases on each wing plate 12, the portion of the wing plate 12 located between the two creases can be formed as the side wall of the packaging box, and the portion of the wing plate 12 located between the second crease 15 (with the direction closer to the center area 11 as the inner side and the direction farther from the center area 11 as the outer side) and the free end can be formed as the top wall of the packaging box.

[0036] In this embodiment, by setting a first crease 14 and a second crease 15 and folding the protective film 100 according to the first crease 14 and the second crease 15, the protective film 100 can be folded into a regular protective box, which not only facilitates further packaging but also improves the aesthetics of the protective box.

[0037] In some embodiments, the polygon formed by multiple first folds 14 and the polygon formed by multiple second folds 15 are coaxially arranged. This results in a protective box with a regular and aesthetically pleasing shape formed by folding the protective film 100.

[0038] Specifically, refer to Figures 3-4The wing plates 12 can be folded in the order of numbers ①-④, thereby allowing the protective film 100 to be folded from... Figure 1 The structure shown is formed by folding. Figure 2 The structure shown.

[0039] In some embodiments, the distance between the first crease 14 and the second crease 15 is approximately the same as the thickness of the product to be packaged. This allows the protective box to fit the product and prevents the product from shifting inside the protective box.

[0040] In some embodiments, the free end of the wing plate 12 is rounded, and the connection between the wing plate 12 and the central region 11 is formed as an arc. The rounded corner reduces the sharpness of the wing plate 12, thereby preventing scratches to the user; while the arc reduces tearing at this location. A second aspect of the present invention also provides an electronic product, including a packaging box and a protective film 100 as described above. The structure of the protective film 100 is as described in the above embodiments. Since the electronic product in this embodiment includes the protective film 100 in all the above embodiments, it also has at least all the beneficial effects of the above embodiments, which will not be repeated here.

[0041] Furthermore, the electronic product also includes an electronic device 20, which is housed within a protective case formed by the protective film 100. This electronic device 20 can be a smart bracelet, smartwatch, or similar device.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
