Description

Technical Field

[0001] The present application relates to the field of film sticking tools, and in particular to a dust-free film sticking packaging box and a film sticking kit. Background Art

[0002] In order to protect the screens of mobile phones, tablets and other terminal devices, users usually apply a layer of film on the flat surface of the terminal device (the device to be filmed) to prevent the touch screen from being scratched. During the film application process, in order to pursue smooth lines and avoid bubbles, so that the appearance of the terminal device remains beautiful, a film applicator is usually used to assist the user in precise positioning and film application, so that the film application effect can be improved.

[0003] Existing film applicators, when in use, have a terminal limiting cavity on the upper surface of the housing and a film-applying limiting portion outside the terminal limiting cavity. The mobile terminal to be film-applied is placed in the terminal limiting cavity for positioning, and then the protective film is attached to the film-applying limiting portion to position the protective film. At this point, the protective film is positioned above the mobile terminal screen, aligning the two and ensuring a relatively straight film-applying position. However, this film applicator requires a separate packaging box, which must be packaged and sold before it is sold, resulting in high production costs.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

Detailed implementation manners

[0039] To make the purpose, technical solutions and advantages of the present application clearer and more definite, the following further describes the present application in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0040] The structure of the existing film sticking case usually adopted not only requires an additional configuration of a packaging box, resulting in a higher production cost. Moreover, during the film sticking process, usually one film sticking case is only used for film sticking on a mobile terminal of a single size specification, which leads to the problem of poor versatility. In addition, during the film sticking process of the film sticking case, the upper part is open, which makes it easy for external dust to enter the inside of the film sticking case and interfere with the film sticking process, resulting in the problem of dust entering between the protective film and the screen of the mobile terminal. In view of the above disadvantages of the existing film sticking case, the following embodiments are proposed in this solution to improve the above problems, specifically as follows:

[0041] Embodiment 1

[0042] As Figure 2 shown, this embodiment proposes a dust-free film sticking packaging box for film sticking on the screen of a mobile terminal to be film stuck. The mobile terminal in this embodiment can be various electronic devices, such as mobile phone 10, tablet computer, e-book, smart watch, etc. For the convenience of describing the structure of this embodiment, mobile phone 10 is taken as an example for illustration. Taking the long side direction of mobile phone 10 as the length direction (front-back direction), the short side direction as the width direction (left-right direction), and the thickness direction as the up-down direction, the structural descriptions of each component in this embodiment are all based on the above standards as references.

[0043] As Figure 2 、 Figure 5As shown, this dust-free film packaging box is used to bond the protective film 400 to the screen of the mobile phone 10. The formation of the protective film 400 mainly includes: a film-applying layer 410, a positioning release layer 420, and a tearing release layer 430. The film-applying layer 410 (the film piece that is actually to be pasted on the screen surface) is used to adhere to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10; the positioning release layer 420 is detachably disposed on one side of the film-applying layer 410, and the positioning release layer 420 is used to connect to this dust-free film packaging box to achieve the positioning of the film-applying layer 410. The tearing release layer 430 is disposed on the side of the film-applying layer 410 facing away from the positioning release layer 420 and faces the mobile phone 10. When in use, both the positioning release layer 420 and the tearing release layer 430 are pulled away from the film-applying layer 410, and only the film-applying layer 410 is bonded to the screen surface of the mobile phone 10.

[0044] As Figure 1 , Figure 2 shown, a dust-free film packaging box of this embodiment mainly includes: a bottom case 100 and a cover 200. To match the shape of the mobile phone 10, the outer contour of the bottom case 100 and the cover 200 on the horizontal plane is rectangular. Therefore, when describing the structure, its directions refer to the length direction, width direction, and thickness direction of the mobile phone 10 (the directions are the same). A terminal limiting cavity 110 is provided on the bottom case 100, and the terminal limiting cavity 110 is used to accommodate and limit the mobile phone 10 to be film-applied. The upper side of the terminal limiting cavity 110 is open, facilitating the mobile phone 10 to be placed into the terminal limiting cavity 110. The cover 200 is pivotally connected to one side of the bottom case 100, and a film-applying limiting portion 210 is provided on the cover 200. The film-applying limiting portion 210 is used to connect and limit the protective film 400. As Figure 2 , Figure 3 shown, for example, the cover 200 is movably connected to the left side of the bottom case 100, and the cover 200 covers the open side of the terminal limiting cavity 110 by pivoting towards the bottom case 100, so that the protective film 400 on the cover 200 faces the screen of the mobile phone 10.

[0045] As Figure 1 , Figure 3 shown, when the cover 200 is pivoted from left to right and covers the bottom case 100, the side of the cover 200 facing the terminal limiting cavity 110 is the inner side, and the side opposite to the inner side is the outer side. As Figure 1 , Figure 2 shown, during the film-applying process, when the cover 200 is pivoted away from the bottom case 100, the terminal limiting cavity 110 is opened, and the inner side of the cover 200 faces upwards. The mobile phone 10 to be film-applied is placed into the terminal limiting cavity 110 and limited; then the protective film 400 is connected to the film-applying limiting portion 210 on the inner side of the cover 200. As Figure 2 , Figure 3As shown, after the cover body 200 is flipped and covers the bottom shell 100, the protective film 400 is located above the bottom shell 100 through the flipping of the cover body 200, and the protective film 400 is located above the mobile phone 10 and aligned with its screen through the limiting effect of the film sticking limiting part 210. In this way, a relatively accurate alignment is achieved during the film sticking process, which can well ensure that the film sticking position is relatively correct. Therefore, by movably connecting the cover body 200 and the bottom shell 100, and enabling the cover body 200 to open the terminal limiting cavity 110 on the bottom shell 100 by flipping or cover the bottom shell 100 by flipping, the cover body 200 and the bottom shell 100 not only realize the film sticking function, but can also be directly used as a packaging box. Therefore, there is no need to separately design a packaging box, which is simple and practical, saves resources and costs. And during the film sticking process, after the cover body 200 is flipped and covers the bottom shell 100, the film sticking operation is carried out, which avoids external dust from entering the inside during the film sticking process and interfering with the film sticking, thus realizing dust-free and accurate film sticking.

[0046] As Figure 1 、 Figure 2 shown, further, the bottom shell 100 in this embodiment specifically includes: a bottom plate 120 and a first frame 130. The bottom plate 120 is a square plate-like structure, and the cover body 200 is connected to one side (left side) in the width direction of the bottom plate 120. The first frame 130 is arranged on the upper surface of the bottom plate 120. The first frame 130 is a semi-surrounding or full-surrounding structure and encloses the terminal limiting cavity 110. The side of the terminal limiting cavity 110 facing away from the bottom plate 120 is open, so that the mobile phone 10 can be placed into the terminal limiting cavity 110. By setting the first frame 130, the limiting function of the mobile phone 10 can be realized. In addition, it can cooperate with the cover body 200. When the cover body 200 is flipped and covers the bottom plate 120, the first frame 130 supports the cover body 200 and cooperates with the cover plate 220 for limiting, so that the cover body 200 can be accurately aligned with the bottom shell 100 after being folded.

[0047] As Figure 1 、 Figure 2 、 Figure 4As shown in the figure, further, at one end of the first frame 130 in the length direction within the present embodiment, a first plug block 140 is provided, and the first plug block 140 can be replaceably set according to different mobile phone specifications. For example: multiple specifications of the first plug block 140 can be prepared according to different specifications of the mobile phone 10. According to the size specifications of the mobile phone 10 to be film-applied, the corresponding first plug block 140 is selected and adhesively installed into the first frame 130. On the inner wall of the first frame 130 opposite to the first plug block 140, a length abutment limiting portion 131 is provided, and the first plug block 140 and the length abutment limiting portion 131 respectively abut against both ends of the mobile phone 10 in the length direction. On one side of the first frame 130 in the width direction, a second plug block 150 is provided, and the second plug block 150 can be replaceably set according to different mobile phone specifications. Multiple specifications of the second plug block 150 can be prepared according to different specifications of the mobile phone 10. According to the size specifications of the mobile phone 10 to be film-applied, the corresponding second plug block 150 is selected and adhesively installed into the first frame 130. On the inner wall of the first frame 130 opposite to the second plug block 150, a width abutment limiting portion 132 is provided, and the second plug block 150 and the width abutment limiting portion 132 respectively abut against both sides of the mobile phone 10 in the width direction. By using the detachable first plug block 140 and second plug block 150 for matching according to the different sizes of the mobile phone 10, for mobile phones 10 of different sizes, only the sizes of the first plug block 140 and the second plug block 150 need to be selected for precise positioning, and the universality is stronger. For the manufacturer, for different mobile phone products, only different first plug blocks 140 and second plug blocks 150 need to be produced, and the other main components can adopt the same structure, which saves materials and is convenient for production.

[0048] As Figure 1 , Figure 2 , Figure 4 As shown in the figure, in the specific structure, the first plug block 140 is detachably provided on the rear end of the upper surface of the bottom plate 120, and the front surface of the first plug block 140 is used to abut against the rear end of the mobile phone 10. An abutment step is provided inside the front part of the first frame 130 to form a length abutment limiting portion 131, and the inner wall surface of the abutment step is used to abut against the front end of the mobile phone 10, so as to realize the limitation of the mobile phone 10 in the length direction. The second plug block 150 is detachably provided on the right side of the first frame 130. The right surface of the second plug block 150 abuts against the inner wall of the first frame 130, and the left surface of the second plug block 150 abuts against the right side of the mobile phone 10. The inner wall on the left side of the first frame 130 is used as the width abutment limiting portion 132, and the left side of the mobile phone 10 is abutted against by the inner wall on the left side of the first frame 130, so as to realize the limitation of the mobile phone 10 in the width direction. The back surface of the mobile phone 10 abuts against the surface of the bottom case 100, so that the mobile phone 10 is stably limited.

[0049] As Figure 1 , Figure 2 , Figure 4As shown, further, an installation groove 141 is formed in the first frame 130. The installation groove 141 extends along the length direction. The first plug 140 is detachably arranged in the installation groove 141. The installation groove 141 is a strip-shaped groove, which is formed on the bottom plate 120 and extends along the length direction. By using the strip-shaped installation groove 141, first plugs 140 with different lengths can be embedded.

[0050] As Figure 1 , Figure 2 , Figure 4 As shown, further, a plurality of installation grooves 141 are arranged side by side along the width direction, and a plurality of corresponding first plugs 140 are provided. In this embodiment, there are 2 installation grooves 141, and 2 corresponding first plugs 140 are provided. The two first plugs 140 abut and limit the mobile phone 10 in the width direction, which can avoid the charging port position of the mobile phone 10 and ensure the limiting stability. It is easy to think that only 1 first plug 140 can be provided, and 1 or more second plugs 150 can be provided.

[0051] As Figure 1 , Figure 2 , Figure 4 As shown, inside the first frame 130 and on the bottom plate 120, an avoidance counter bore 160 is further formed. The avoidance counter bore 160 is used to avoid the protruding area on the back of the mobile phone 10, so that the mobile phone 10 can be stably placed in the terminal limiting cavity 110.

[0052] As Figure 1 , Figure 2 As shown, further, the cover body 200 of this embodiment specifically includes a cover plate 220. The film sticking limiting part 210 includes a first limiting part 211 and a second limiting part 212. The cover plate 220 has an inner surface facing the open side of the terminal limiting cavity 110 through flipping. The first limiting part 211 is arranged at one end in the length direction on the inner surface of the cover plate 220 and is used to connect one end in the length direction of the positioning release layer 420 of the protective film 400. The second limiting part 212 is arranged at the other end in the length direction on the inner surface of the cover plate 220 and is used to connect the other end in the length direction of the positioning release layer 420 of the protective film 400. By respectively arranging the first limiting part 211 and the second limiting part 212 at both ends in the length direction, the entire protective film 400 can be connected to the cover body 200 through the positioning release layer 420. When the cover plate 220 is flipped, the entire protective film 400 can be aligned with the screen of the mobile phone 10.

[0053] As Figure 1 , Figure 2 , Figure 5As shown, further, the first limiting portion 211 of this embodiment includes: at least two first hanging posts 211a, the at least two first hanging posts 211a are arranged at intervals in the width direction, and the first hanging posts 211a are used to connect and position the pulling holes 421 at one end of the length direction of the release layer 420. The second limiting portion 212 includes: a second hanging post 212a, the second hanging post 212a is located at the middle position in the width direction, and the second hanging post 212a is used to connect and position the limiting holes 422 at the other end of the length direction of the release layer 420.

[0054] By having the first hanging post 211a and the second hanging post 212a located at both ends of the length direction of the cover plate 220 respectively, and the first hanging post 211a and the second hanging post 212a are respectively used to connect both ends of the length direction of the protective film 400, so that the protective film 400 is connected to the cover plate 220, and when the cover body 200 is folded over the bottom shell 100, the protective film 400 can be stably spaced from the mobile phone 10 by a predetermined distance. And the two first hanging posts 211a make the width direction of the protective film 400 be relatively stably limited, and it is not easy for the protective film 400 to shift on the cover body 200.

[0055] As Figure 1 、 Figure 2 、 Figure 5 As shown, further, an elastic pressing area 240 is provided on the cover plate 220. The elastic pressing area 240 can be a long strip-shaped sunken groove (not through) provided in the middle of the cover plate 220. The thickness of the elastic pressing area 240 is smaller than the thickness of the cover plate 220. The cover plate 220 is usually made of plastic and has a certain elasticity itself. Since the thickness of the elastic pressing area 240 is smaller, it is easy to deform when pressed. By adopting the structure of the non-through long strip-shaped sunken groove, in addition to pressing the protective film 400 onto the screen of the mobile phone 10 by pressing downwards, it can also play a role in dust prevention.

[0056] As Figure 1 、 Figure 2 [[ID= XIX]]、 Figure 5 As shown, a flexible pad 241 is provided on the inner surface of the elastic pressing area 240. The flexible pad 241 has a certain elasticity. When pressed, it can transmit pressure to press the protective film 400 downwards, and can buffer the extrusion force, making the pressing process during the film application more uniform in force and the film application effect better.

[0057] As Figure 1 、 Figure 2 、 Figure 4As shown in the figure, further, a second border 230 is provided on the cover plate 220. The second border 230 can adopt a fully enclosed structure or a semi-enclosed structure. The second border 230 protrudes from the inner surface of the cover plate 220 and is matingly docked with the first border 130. For example, the second border 230 is used to sleeve outside the first border 130. In this way, when the cover body 200 is folded and covered on the bottom shell 100, the second border 230 can be docked with the first border 130, so as to achieve a relatively accurate covering and docking. One side in the length direction of the second border 230 of this embodiment is provided with an opening on the end surface, and one side in the length direction of the first border 130 is provided with an opening under the end surface. By flipping the cover plate 220, the opening on the end surface is connected to the opening under the end surface to form a pulling outlet 250. The pulling outlet 250 is used to accommodate the tearing release layer 430 of the protective film 400. The tearing release layer 430 of the protective film 400 extends out from the pulling outlet 250 to facilitate the user to hold by hand, and the separated tearing release layer 430 is removed from the pulling outlet 250, so that the film sticking layer 410 on the protective film 400 is exposed and aligned with the mobile phone 10 screen below.

[0058] As Figure 1 , Figure 2 , Figure 3 As shown in the figure, further, the cover body 200 of this embodiment is connected to the bottom shell 100 through a bending plate 300; the lower end of the bending plate 300 is fixedly connected to the bottom shell 100, and one side in the width direction of the cover body 200 is flip-connectedly connected to the upper end of the bending plate 300.

[0059] As Figure 1 , Figure 2 , Figure 3 As shown in the figure, in the specific structure, the cover plate 220 of the cover body 200 includes: an inner cover plate 221 and an outer cover plate 222. The inner cover plate 221, the second border 230, the first limiting portion 211 and the second limiting portion 212 are directly integrally formed by injection molding, and the overall structure of the inner cover plate 221 can be adhered to the outer cover plate 222. The bottom plate 120 of the bottom shell 100 includes: an inner bottom plate 121 and an outer bottom plate 122. The inner bottom plate 121 and the first border 130 are directly integrally formed by injection molding, and the overall structure of the inner bottom plate 121 can be adhered to the outer bottom plate 122. The bending plate 300 is connected between the outer bottom plate 122 and the outer cover plate 222. In this way, the structure is optimized and the production is facilitated.

[0060] Embodiment 2

[0061] As Figure 1 , Figure 5As shown, this embodiment provides a film-applying kit, which includes the aforementioned dust-free film-applying box and a protective film 400. The bottom shell 100 of the dust-free film-applying box is used to accommodate and position the mobile phone 10 to be film-applied. The protective film 400 is placed on the cover 200 of the dust-free film-applying box and is turned over to face the screen of the mobile phone 10.

[0062] like Figure 2 、 Figure 5 As shown, the protective film 400 in this embodiment specifically includes: a film layer 410, a positioning release layer 420, and a tear-off release layer 430. The film layer 410 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 420 is detachably provided on one side of the film layer 410 and is used to be connected to the film applicator. The positioning release layer 420 is provided with a pull hole 421 at one end along its length and a limit hole 422 at the other end; the pull hole 421 can be fitted over the first limit portion 211; the limit hole 422 is used to fit over the second limit portion 212 for positioning. The tear-off release layer 430 is provided on the side of the film layer 410 away from the positioning release layer 420 and faces the mobile phone 10.

[0063] like Figure 2 、 Figure 3 、 Figure 5 As shown, when in use, the cover 200 is first flipped away from the bottom shell 100, and the mobile phone 10 is placed into the opened terminal limiting cavity 110 for limiting. The pull hole 421 of the positioning release layer 420 is sleeved on the first hanging column 211a of the flipped cover 200, and the limiting hole 422 of the positioning release layer 420 is sleeved on the second hanging column 212a, so that the protective film 400 is limited in the terminal limiting cavity 110. After the cover 200 is flipped and covered on the bottom shell 100, the tear-off layer 430 is pulled out from the pull-out opening 250 to expose the film layer 410. By pressing down on the upper surface of the cover 200, the elastic pressing area 240 is deformed downward to press down the protective film 400, and the film layer 410 can be pressed down and adhered to the surface of the screen of the mobile phone 10. The cover 200 is then turned over to open the terminal limiting cavity 110 , and finally the release layer 430 is torn off, so that only the film layer 410 is adhered to the screen of the mobile phone 10 , and the film is completed.

[0064] In summary, for a dust-free film application packaging box and a film application kit in this application, the structure is simplified. For mobile phones of different sizes, precise positioning of mobile phones of different specifications can be achieved by only adjusting the sizes of the first plug block and the second plug block. By movably connecting the cover body and the bottom shell, and enabling the cover body to open the terminal limiting cavity on the bottom shell by flipping or cover the bottom shell by flipping, the cover body and the bottom shell can not only realize the film application function, but also be directly used as a packaging box. Therefore, there is no need to separately design a packaging box, which is simple and practical, saves resources and costs. And during the film application process, after the cover body is flipped and covered on the bottom shell, the film application operation is carried out, avoiding external dust from entering the inside during the film application process and interfering with the film application, so as to achieve dust-free and precise film application.
