[0001] This application relates to the technical field of mobile phone screen protectors, and more specifically, it relates to an integrated flip-type mobile phone screen protector box. Background Technology

[0002] Currently, mobile phones have become an indispensable electronic product in people's lives. For touch screen phones, the touch screen is easily scratched, which affects the display effect and aesthetics of the screen. Therefore, a glass film is usually pasted on the touch screen.

[0003] The current method of applying screen protectors involves manually aligning the film by eye before pasting it onto the touchscreen. However, manual alignment requires considerable skill; otherwise, inaccurate positioning can result in the film not completely covering the touchscreen, affecting both the protective effect and the aesthetics. Consequently, various types of screen protector applicators or devices have emerged on the market, with flip-top screen protector boxes being the most common.

[0004] Flip-type screen protector boxes typically include an upper cover, a lower cover, and a hinge that connects the upper and lower covers. The lower cover has a positioning groove for positioning the phone, and the upper cover has a film fixing structure for positioning the film assembly. The film assembly is attached to the phone screen by flipping the upper and lower covers together. However, the separate upper and lower covers and the hinge are structurally complex and have high mold and assembly costs. Utility Model Content

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1 and Figure 2 A one-piece flip-type mobile phone screen protector box includes an upper cover 1, a lower cover 2, and a middle connecting piece 3. One side of the middle connecting piece 3 is connected to one end of the upper cover 1, and the opposite side of the middle connecting piece 3 is connected to one end of the lower cover 2. The upper cover 1, lower cover 2, and middle connecting piece 3 are integrally vacuum-formed. During vacuum forming, the middle connecting piece 3 gradually thins from both sides towards the center, with the thickness of the thinned area being 0.1-0.4mm, facilitating bending and allowing the upper cover 1 and lower cover 2 to flip towards each other. The lower cover 2 is formed with a positioning groove 21 for positioning the mobile phone, and the upper cover 1 is formed with a fitting groove 11 that matches the outer contour and shape of the lower cover 2. The upper cover 1 passes through the lower cover 2 into the fitting groove 11 and closes with the lower cover 2. The upper cover 1 also has a film positioning groove 12 recessed on the bottom surface of the fitting groove 11, in which a film positioning groove 12 is positioned. The film assembly 4, with the upper cover 1 and lower cover 2 tightly fastened by the fitting groove 11, facilitates the blocking of external dust and reduces dust from sticking to the mobile phone screen during film application, thus affecting the film application effect. The film 41 assembly 4 is positioned by the film positioning groove 12 set in the fitting groove 11. The upper cover 1 and lower cover 2 close the film assembly 4 and automatically align it with the screen, allowing the film assembly 4 to adhere to the screen without manual visual adjustment, thus lowering the operation threshold. In this application, the upper cover 1, lower cover 2 and middle connecting piece 3 are integrally formed by vacuum forming, eliminating the independent hinge parts (such as metal shafts, plastic buckles, etc.) of traditional flip boxes, reducing the number of parts and production assembly steps, significantly reducing mold opening and assembly costs. The vacuum forming process only requires a single plastic sheet, which results in lower material loss compared to injection molding or separate packaging, meeting the requirements of low-cost mass production.

[0021] Reference Figure 2 Furthermore, the film assembly 4 includes a positioning film 41, a protective film 42, and a release film 43. The protective film 42 is attached to one side of the positioning film 41 by an adhesive layer, and the release film 43 is attached to the side of the protective film 42 away from the positioning film 41 by an adhesive layer. The size and outer contour of the positioning film 41 match the size and inner contour of the film positioning groove 12. By matching and placing the positioning film 41 in the film positioning groove 12, the protective film 42 is pre-positioned and attached to the positioning film 41, thereby positioning the relative position of the protective film 42 and the mobile phone screen, thus achieving precise attachment of the protective film 42 to the mobile phone screen. The release film 43 is set to protect the protective film 42 when it is not in use, preventing dust and dirt from contaminating the protective film 42. When applying the film, the release film 43 needs to be peeled off from the protective film 42. The positioning film 41 and the release film 43 are both PET films, and the protective film 42 is a tempered glass film.

[0022] Reference Figure 1 and Figure 2Furthermore, a support portion 411 is provided at one end of the positioning film 41, and a fixing portion 412 is provided at the other end of the positioning film 41. A first through groove 13 is provided on the end face of the upper cover 1 near the lower cover 2. The first through groove 13 connects to the film positioning groove 12 and penetrates the bottom surface of the upper cover 1. A film fixing structure 14 is provided at the bottom end of the first through groove 13 on the upper cover 1. The fixing portion 412 of the positioning film 41 is accommodated in the first through groove 13 and connected to the film fixing structure 14 for fixation. A slot 15 is recessed on the end wall of the film positioning groove 12 away from the first through groove 13 on the upper cover 1. The fixing part 412 of 41 passes through the slot 15. The fixing part 412 of the positioning film 41 is fixed by the film fixing structure 14 to fix the positioning film 41, thereby fixing the entire film assembly 4. The slot 15 limits and supports the positioning film 41 support part 411, so that the film assembly 4 is placed stably in the upper cover 1, which facilitates the transportation and carrying of the film box and the film assembly 4. The film assembly 4 is not easy to be damaged by collision with the upper cover 1 and the lower cover 2 during transportation and carrying. At the same time, due to the fixing of the positioning film 41, the film assembly 4 is not easy to be misaligned when the upper cover 1 is flipped.

[0023] Reference Figure 1 and Figure 2 Furthermore, a strip handle 44 is provided at one end of the release film 43 near the fixing part 412 of the positioning film 41. The strip handle 44 is folded towards the side of the release film 43 away from the protective film 42 and extends to the opposite end of the release film 43. A grip part 441 is also provided at the end of the strip handle 44. After the grip part 441 of the strip handle 44 is folded in half, it is inserted into the slot 15. The upper cover 1 also has a second through groove 16 at the end of the film positioning groove 12 away from the first through groove 13 for the strip handle 44 to pass through. The slot 15 is used to hide the strip handle 44, so that when not in use, the strip handle 44 is hidden and does not easily rub against other items in the packaging bag, causing accidental detachment and premature tearing of the release film 43. It is also not easy to get oil stains, which would cause oil stains to contaminate the entire film assembly 4 through the strip handle 44. At the same time, the hidden strip handle 44 makes the overall appearance of the film box highly integrated. When in use, by unfolding the gripping part 441 of the strip handle 44 and passing it through the second through slot 16 through the upper cover 1, the release film 43 can be gradually peeled off during the film application process. With the upper cover 1 and the lower cover 2 closing and sealing, it helps to reduce dust from sticking to the protective film 42 or the screen during the film application process, thus reducing the impact on the film application effect.

[0024] Reference Figure 1 and Figure 2Furthermore, the membrane fixing structure 14 includes a first positioning protrusion 141, a second positioning protrusion 142, and a third positioning protrusion 143. The second positioning protrusion 142 and the third positioning protrusion 143 are located on the side of the first positioning protrusion 141 away from the membrane positioning groove 12, and the second positioning protrusion 142 and the third positioning protrusion 143 are arranged at intervals along the width direction of the membrane positioning groove 12. The fixing part 412 of the positioning membrane 41 is provided with a first positioning hole 4121, a second positioning hole 4122, and a third positioning hole 4123. The first positioning hole 4121 is used for the first positioning protrusion 141 to pass through, and the second positioning hole 4122 is used for the second positioning protrusion 141 to pass through. 2. Insertion: The third positioning hole 4123 is used for the third positioning protrusion 143 to insert. The dimensions of the first positioning hole 4121, the second positioning hole 4122, and the third positioning hole 4123 are respectively matched with the dimensions of the first positioning protrusion 141, the second positioning protrusion 142, and the third positioning protrusion 143. The top peripheral walls of the first positioning protrusion 141, the second positioning protrusion 142, and the third positioning protrusion 143 are all provided with barbs. The barbs support the fixing part 412 of the positioning film 41. The fixing part 41 of the positioning film 41 uses the flexible deformation property of PET to allow the positioning hole to be inserted into the positioning protrusion with barbs.

[0025] Reference Figure 1 Furthermore, the top cover 1 has a protruding strip 17 at one end of the bottom surface of the film positioning groove 12 near the card slot 15. The length of the protruding strip 17 extends along the width direction of the film positioning groove 12. The protruding strip 17 supports the film assembly 4 so that the film assembly 4 is tilted relative to the mobile phone screen. When the film is tilted and applied, one edge of the protective film 42 contacts the screen first. Through the adhesion of the adhesive layer, the protective film 42 is gradually attached to the mobile phone screen. Air will naturally be discharged from the contact point to the unattached area, reducing the probability of air being "sealed" in the film and ensuring the quality of the film application.

[0026] Reference Figure 1 Furthermore, the upper cover 1 has a locking block 18 protruding from the inner peripheral wall of the fitting groove 11, and the lower cover 2 has a buckle groove 22 that matches the shape and size of the locking block 18 on its outer peripheral wall. The protrusion height of the locking block 18 is 1-3mm, and its surface is arc-shaped. Through the deformation ability of the plastic, when the upper cover 1 and the lower cover 2 are closed, the locking block 18 is inserted into the buckle groove 22, and the upper cover 1 and the lower cover 2 are fixed together, so that the upper cover 1 and the lower cover 2 are not easy to open during transportation or carrying, which would affect the transportation.

[0027] Reference Figure 1 Furthermore, slots 23 are provided on both sides of the outer periphery of the lower cover 2. Both slots 23 are connected to the positioning groove 21 and penetrate the top surface of the lower cover 2. The two slots 23 are aligned, and the two slots 23 facilitate the insertion of human fingers into the positioning groove 21 to hold the mobile phone and pull it out of the positioning groove 21.

[0028] Reference Figure 1 Furthermore, the top cover 1 has a bubble-pressing groove 19 extending through it on the bottom surface of the film positioning groove 12. The bubble-pressing groove 19 allows for observation of the film application status during the application process. When there are residual air bubbles in the film, a finger can be inserted into the film positioning groove 12 to press the protective film 42, thereby expelling the air bubbles between the protective film 42 and the mobile phone screen and ensuring the film application effect.
