[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0047] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be located directly or indirectly on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on this technical solution. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0048] Furthermore, existing film applicators not only require the use of the outer packaging bag of the protective film when applying the film, but also during the film application process, after aligning the protective film with the mobile phone screen, the user directly presses the protective film. For users who are not familiar with film application, they may press the middle of the film first, which may lead to incorrect pressing and the formation of bubbles after the protective film is adhered. Therefore, this application proposes the following embodiments:

[0049] Example 1

[0050] like Figure 1 、 Figure 6 、 Figure 7 As shown, this embodiment proposes a film packaging box for applying film to the screen of a mobile terminal to be applied with film. The mobile terminal in this embodiment can be various electronic products, such as mobile phones 10, tablet computers, e-books, smart watches and other electronic devices. To facilitate the structural description of this embodiment, the mobile phone 10 is taken as an example for explanation. The long side direction of the mobile phone 10 is the length direction (front and back direction), the short side direction is the width direction (left and right direction), and the thickness direction is the up and down direction. This film packaging box is used to adhere the film part of the protective film 20 to the screen of the mobile phone 10. The protective film 20 can take various forms, such as Figure 3 As shown, for example, one embodiment primarily includes: a film layer 24, a positioning release layer 21, and a tear-off release layer 25. The film layer 24 (the film actually attached to the screen surface) is used to attach to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10; the positioning release layer 21 is detachably disposed on one side of the film layer 24 and is used to connect to the film packaging box. The tear-off release layer 25 is disposed on the side of the film layer 24 facing away from the positioning release layer 21 and toward the mobile phone 10. During use, both the positioning release layer 21 and the tear-off release layer 25 are pulled away from the film layer 24, leaving only the film layer 24 adhered to the screen surface of the mobile phone 10.

[0051] like Figure 1 、 Figure 2 、 Figure 3 As shown, the film packaging box of this embodiment mainly includes: a shell 100, a cover 200 and an elastic member 300. The shell 100 can be set as a square structure, and the shell 100 is placed flat when in use. A accommodating cavity 110 is provided in the shell 100, and the accommodating cavity 110 is open upward. The accommodating cavity 110 is used to accommodate and limit the mobile terminal to be film-applied. The cover 200 can be covered on the shell 100. A film-applying cavity 210 is provided on one side of the cover 200. The film-applying cavity 210 is used to connect and limit the protective film 20. The cover 200 can be detachably covered on the shell 100, or it can be flipped on one end and covered on the shell 100. When the cover 200 is covered on the shell 100, the open side of the film-applying cavity 210 faces downward, so that the protective film 20 limited in the film-applying cavity 210 can face the screen of the mobile phone 10 below. The elastic member 300 is disposed on the cover 200 and located within the film receiving cavity 210. The elastic member 300 is used to apply elastic force toward the receiving cavity 110, thereby squeezing the protective film 20. When the cover 200 is placed on the housing 100, the protective film 20, compressed at its lower end by the elastic member 300, abuts against the lower end of the phone 10 screen, creating a pre-compression force between the lower ends of the protective film 20 and the lower end of the phone 10 screen. When the release layer 25 is removed, the elastic member 300 rebounds, causing the exposed film layer 24 and the phone 10 screen to be locally stressed at their lower ends. This allows the lower ends to be initially compressed by the elastic member 300 and adhere to the phone 10 screen, thus facilitating air evacuation.

[0052] like Figure 1 、 Figure 3 、 Figure 4 As shown, the present application provides a film packaging box that is provided with an accommodating inner cavity 110 in the shell 100, so that the mobile terminal to be film-applied is placed in the accommodating inner cavity 110 and the position is limited. A film accommodating cavity 210 is provided on one side of the cover body 200, and the film accommodating cavity 210 is used to connect and limit the protective film 20. After the shell 100 is covered with the cover body 200, the protective film 20 that has been limited on the cover body 200 is facing the screen of the mobile terminal below. The protective film 20 can be installed in the film accommodating cavity 210 of the cover body 200 in advance, so that after the cover body 200 is covered on the shell 100, the protective film 20 is placed inside the entire film packaging box, so that the film packaging box can be used for both film application and forming the outer packaging of the protective film 20. Therefore, the use of packaging bags for the protective film 20 is reduced, saving production costs and reducing production processes.

[0053] like Figure 1 、 Figure 6 、 Figure 7As shown, due to the elastic force of the elastic member 300 disposed on the cover 200 and located within the film receiving cavity 210, when the cover 200 is placed on the housing 100, the protective film 20 and the screen of the mobile phone 10 are pre-pressed. For example, the rear end of the protective film 20 abuts against the screen, while the front end remains spaced apart from the screen. When the release layer 25 on the protective film 20 is removed, the film layer 24 is exposed and faces the screen of the mobile phone 10. Due to the elastic force of the elastic member 300, the film layer 24 of the protective film 20 is first bonded to the lower end of the screen due to the squeezing force of the elastic member 300. The upper end of the protective film 20 remains spaced apart from the screen of the mobile phone 10. After the rear end is bonded, air begins to be exhausted. The user then presses down on the protective film 20, causing the film layer 24 of the protective film 20 to gradually adhere to the screen of the mobile phone 10 from the back to the front through the AB glue, achieving a regular bonding of the protective film 20 from the stressed end (rear end) to the other end (front end). In this way, the first bonding end is gradually degassing toward the rear bonding end, effectively avoiding the generation of bubbles during the film lamination process.

[0054] like Figure 1 、 Figure 3 As shown, the cover 200 of this embodiment specifically includes: a cover plate 240 and side ribs 250 disposed on both sides of the cover plate 240 in the width direction. The cover plate 240 and the side ribs 250 enclose a film receiving cavity 210. A tear opening 241 is formed at one end of the film receiving cavity 210 in the length direction. The tear opening 241 is used to allow the release layer 25 of the protective film 20 to pass through the film receiving cavity 210. When the cover 200 is covered with the housing 100, the tear opening 241 is located at the rear end of the cover 200. The elastic member 300 is disposed on the end of the cover plate 240 near the tear opening 241 and is therefore also located at the rear end of the cover 200. The tear-off layer 25 of the protective film 20 confined in the film accommodating cavity 210 is usually provided with two layers, wherein the upper layer is adhered to the film layer 24 to protect the film layer 24, the front end of the lower layer is fixedly connected to the upper layer, and the rear end of the lower layer passes through the tear-off opening 241. When in use, the tear-off layer 25 that has passed through is directly pulled, so that the lower layer drives the upper layer, so that the front end of the upper layer falls off from the film layer 24 first and contacts the screen of the mobile phone 10 downward. In the process of pulling out the tear-off layer 25, dust on the screen of the mobile phone 10 can be taken away, thereby achieving a dust removal effect.

[0055] like Figure 1 、 Figure 3 、 Figure 4As shown, further, a horizontal bar 260 is provided between the side ribs 250 on both sides of this embodiment. The horizontal bar 260 is located near the end of the side rib 250 near the tear opening 241. The horizontal bar 260 is spaced apart from the cover plate 240 to form a gap for the tear-off layer 25 to pass through. The horizontal bar 260 is located at the rear end of the side rib 250. The horizontal bar 260 is used to bend and accommodate the rear end of the tear-off layer 25 that passes through the gap. The horizontal bar 260 not only enhances the structural strength of the cover body 200, but also provides a turning and bending position for the rear end of the lower layer of the tear-off layer 25, so that the rear end of the lower layer of the tear-off layer 25 that passes through the film receiving cavity 210 can be folded around the horizontal bar 260. After being flipped, the rear end of the lower layer of the tear-off layer 25 is inserted forward between the cover body 200 and the shell 100, achieving a good accommodation effect. This makes the present film packaging box more convenient to use as a packaging box.

[0056] like Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 As shown, in this embodiment, the cover plate 240 is further provided with a pressing portion 270. The pressing portion 270 is deformed by compression to press the protective film 20 onto the screen surface of the mobile terminal. When the elastic force of the elastic member 300 causes the adhesive layer 24 of the protective film 20 to initially adhere to the lower end of the screen due to the compression force of the elastic member 300, the pressing portion 270 provides a pressing position for the user to press down on the protective film 20, making it easier for the protective film 20 to be gradually adhered to the screen of the mobile phone 10 due to the downward pressure of the user.

[0057] like Figure 1 、 Figure 3 As shown, the pressing portion 270 of this embodiment further includes a material-reducing groove 271 provided on the cover plate 240. The material-reducing groove 271 is used to reduce the thickness of the cover plate 240 in the area where the pressure is required. Generally, when the cover body 200 is made of plastic and the thickness is reduced, the material-reducing groove 271 area of the cover plate 240 will deform significantly when pressed. The large deformation can press and adhere the protective film 20 below to the mobile phone 10.

[0058] It is easy to imagine that the pressing portion 270 can also be in the form of a through hole or an elastic rubber strip.

[0059] like Figure 3As shown, further, the material reduction groove 271 of this embodiment specifically includes: a first material reduction area 272, a second material reduction area 273 and a third material reduction area 274 arranged along the width direction. The first material reduction area 272 is square and extends a certain length in the width direction. The elastic member 300 is arranged in the middle position of the width direction within the first material reduction area 272. The second material reduction area 273 extends along the length direction and one end is connected to the first material reduction area 272. The third material reduction area 274 is connected along the width direction, and the other end of the second material reduction area 273 is connected to the third material reduction area 274. The first material reduction area 272 facilitates the bonding and fixing of the elastic member 300, the second material reduction area 273 facilitates the user to press the protective film 20 from the back to the front, and the third material reduction area 274 facilitates the user to press the protective film 20 from the left and right directions, so that the protective film 20 is more stably attached to the screen of the mobile phone 10.

[0060] like Figure 3 、 Figure 6 、 Figure 7 As shown, the elastic member 300 of this embodiment further includes an elastic block 310. The elastic block 310 is fixedly connected to the inner surface of the cover body 200 and extends a predetermined length in the width direction. The elastic block 310 can be a sponge block, a soft rubber block, etc. Extending the elastic block 310 in the width direction increases the area of compression applied to the lower end of the protective film 20 in the left-right direction, and the elastic force of the elastic block 310 is applied more evenly.

[0061] like Figure 1 、 Figure 3As shown, further, a membrane connector 220 is provided on the cover body 200 of this embodiment. The membrane connector 220 is used to connect the protective film 20, thereby confining the protective film 20 within the film accommodating cavity 210. The connector of this embodiment specifically includes a first hook 221 and a second hook 222. The first hook 221 is located at one end of the cover body 200 in the longitudinal direction, and the second hook 222 is located at the other end of the cover body 200 in the longitudinal direction. For example, the first hook 221 is provided at the front end of the cover plate 240, while the second hook 222 is provided at the rear end of the cover plate 240. The first hook 221 and the second hook 222 are respectively used to hook the connection holes 22 in the longitudinal direction of the positioning release layer 21 of the protective film 20. The first hook 221 and the second hook 222 effectively limit the protective film 20 in the longitudinal direction, thereby achieving a stable connection between the protective film 20 and the cover body 200. In the specific structure, two first hooks 221 and two second hooks 222 are provided in the width direction. The protective film 20's positioning release layer 21 is provided with connection holes 22 at the front and rear. The connection holes 22 at the front mate with the two first hooks 221, while the connection holes 22 at the rear mate with the two second hooks 222. The protective film 20 is hooked onto the cover 200 via the connection holes 22 in the positioning release layer 21. The two first hooks 221 and two second hooks 222, spaced apart in the left and right directions, limit the protective film 20 in the width direction.

[0062] like Figure 1 、 Figure 3 As shown, the cover 200 of this embodiment is further provided with a positioning post 242, which is designed to mate with a positioning hole 23 on one side of the release layer 21. The positioning post 242 is a tapered post, with a protruding area on one side of the release layer 21 in the left and right directions, and the positioning hole 23 is provided within this protruding area. When hooking the release layer 21 for installation, the positioning hole 23 can be placed over the positioning post 242 to achieve pre-positioning, allowing the release layer 21 to be more quickly hooked onto the first hook 221 and the second hook 222.

[0063] like Figure 1 、 Figure 2 、 Figure 3 As shown, in this embodiment, the cover 200 is provided with a plug-in alignment portion 280, and the housing 100 is correspondingly provided with a docking member 120; the cover 200 is placed on the housing 100 and aligned by plugging the alignment portion 280 into the docking member 120. During the process of connecting the cover 200 to the housing 100, the alignment portion 280 connects to the docking member 120, allowing the protective film 20 attached to the cover 200 to face the screen of the mobile phone 10 placed in the housing 100, thereby achieving more accurate positioning and ensuring the accuracy of the film application process.

[0064] like Figure 1 、 Figure 2 、 Figure 3 As shown, the insertion alignment portion 280 of this embodiment further includes: a post 281, which is arranged in the length and / or width direction of the cover 200. The docking member 120 includes: an insertion hole 121, which is provided on the housing 100 and is configured to mate with the post 281. In a specific structure, four posts 281 can be provided, distributed at the four vertices of a rectangle, so that after mating with the posts 281, effective positioning is achieved in both the length and width directions.

[0065] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, the cover 200 of this embodiment is a flip cover, one end of which is rotatably connected to the housing 100, and the other end is flipped to open or close the accommodating cavity 110. In the specific structure, a rotating post 251 is provided on both sides of the width direction of the front end of the cover 200. A rotating hole 140 is provided on the inner wall of the front end of the housing 100. The rotating post 251 is engaged with the rotating hole 140, so that the cover 200 can be rotated around the rotating post 251 to open or close. A limiting protrusion 252 is also provided on both sides of the width direction of the cover 200, and an opening 150 is provided on the inner wall of the housing 100. When the cover 200 is flipped to close the housing 100, the limiting protrusion 252 is embedded in the opening 150, which can limit the closed position of the cover 200 after flipping. It is easy to imagine that the cover 200 can also be connected in a detachable manner to achieve opening or closing of the housing 100.

[0066] like Figure 1 、 Figure 2 As shown, further, the housing 100 of this embodiment is provided with a replaceable insert 130. The insert 130 is used to abut against the inner wall of one side in the length direction and / or the inner wall of one side in the width direction of the accommodating cavity 110 to adapt to the size of the mobile terminal. For example, two inserts 130 are provided in the length direction of the accommodating cavity 110, and one insert 130 is provided in the width direction. When it is necessary to apply a film to mobile phones 10 of different sizes, the corresponding insert 130 is selected and installed in the accommodating cavity 110. The two L-shaped sides of the accommodating cavity 110 are used as positioning references, and inserts 130 of different sizes are used on the other two sides to fix and adapt to all sizes of mobile phones 10.

[0067] It is easy to imagine that when applying a film to a mobile phone 10 of a certain specification, the film can be directly formed by inserting the mold during the molding process to form a fixed limiting structure.

[0068] Example 2

[0069] like Figure 1、 Figure 3 、 Figure 4 、 Figure 5 As shown, this embodiment provides a film kit, including the film packaging box and the protective film 20 as described above. Figure 3 、 Figure 7 As shown, the protective film 20 includes: a film layer 24, a positioning release layer 21, and a tear-off release layer 25. The positioning release layer 21 is connected to and limited on the cover body 200. The tear-off release layer 25 is pulled out from one side of the cover body 200 to align the film layer 24 with the screen of the mobile terminal. The film layer 24 can be a hard material (such as a tempered film) or a soft material (such as a hydrogel protective film). The film layer 24 is used to be attached to the surface of the mobile phone 10 to protect the screen of the mobile phone 10; the positioning release layer 21 can be detachably provided on one side of the film layer 24. The positioning release layer 21 is used to be connected to the film applicator. The positioning release layer 21 has connection holes 22 at both ends in the length direction, and a positioning hole 23 is provided on one side of the positioning release layer 21 in the width direction. The positioning hole 23 is sleeved on the positioning column 242 on the cover body 200, and then the connection holes 22 at both ends in the length direction can be hooked on the first hook 221 and the second hook 222 respectively for positioning. The tear-off layer 25 is disposed on a side of the film layer 24 that is away from the positioning release layer 21 and faces the mobile phone 10 .

[0070] like Figure 1 、 Figure 2 、 Figure 3 As shown, when in use, the mobile phone 10 is first placed into the accommodating cavity 110 of the housing 100 for positioning. The corresponding inserts 130 can be selected according to the different specifications of the mobile phone 10 and correspondingly arranged in the accommodating cavity 110 to stably position the mobile phone 10 therein. The positioning holes 23 of the positioning release layer 21 are inserted into the positioning posts 242 on the cover 200, and the connection holes 22 of the positioning release layer 21 are hooked onto the first hooks 221 and the second hooks 222, respectively, so that the protective film 20 is positioned on the cover 200. The cover 200 is then flipped over and placed on the housing 100. After the tear-off layer 25 is removed, the film layer 24 is exposed. Due to the action of the elastic member 300, the exposed film layer 24 and the screen of the mobile phone 10 are locally stressed at the lower end. The lower end can be pressed by the elastic member 300 and adhered to the screen of the mobile phone 10, thereby facilitating air exhaust. The user presses the pressing portion 270 from the back to the front, so that the protective film 20 is gradually adhered to the mobile phone 10 from the back to the front. Then the cover 200 is opened, and the tear-off layer 25 is finally torn off to complete the film application.
