Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a mobile phone case packaging box. Background Technology

[0002] Currently, mobile phone case packaging mostly uses plastic blister boxes and rigid cardboard boxes. The phone case is simply placed or loosely wrapped to secure it. During transportation, the phone case is prone to shaking inside the packaging box, and it lacks effective support for soft shells such as silicone and TPU. Long-term storage can easily cause it to collapse or deform due to gravity or compression. Plastic packaging is difficult to degrade, and cardboard packaging often requires the assembly and gluing of multiple parts, resulting in significant material waste and environmental pollution.

If the specific posture changes, the directional indicators will also change accordingly.

[0019] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] See Figures 1 to 3 As shown, the structure of this utility model is as follows: a mobile phone case packaging box, including a base plate 1, with ribs 2 arranged around the base plate 1 to form a receiving cavity 3. The three-dimensional structure of the ribs 2 can not only effectively resist the impact of external pressure on the mobile phone case, but also enhance the overall rigidity of the base plate 1. A protrusion 4 is provided in the middle of the receiving cavity 3, and its shape is precisely adapted to the contour of the inner surface of the mobile phone case. When the mobile phone case is fitted over the protrusion 4, the protrusion 4 fits tightly against the inside of the mobile phone case, restricting the displacement of the mobile phone case and providing uniform support, especially for silicone and TPU. The material is easily deformable, which can prevent the shell from collapsing due to gravity or compression during long-term storage. The bottom of the punch 4 is provided with a groove 5. When the phone case is put into the punch 4, the inward flange of the edge of the phone case is embedded in the groove 5 to prevent the phone case from falling off the punch 4 during transportation. One end of the base plate 1 is connected to the flip cover 7 through the flip-out connecting part 6. The lower surface of the flip cover 7 is provided with a first protrusion 8. The rib 2 is provided with a first recess 9 that matches the first protrusion 8. The shape of the first protrusion 8 and the first recess 9 are matched. When the flip cover 7 is closed, the first protrusion 8 is embedded in the first recess 9 to form a fastening and locking, ensuring that the packaging box remains closed under non-human operation.

[0022] Furthermore, the substrate 1, rib 2, punch 4, flap 7 and connecting part 6 are integrally formed by pulp molding process. Specifically, the integrally formed structure has no splicing, strong structural integrity, impact resistance and good cushioning protection, saving the complex processes of multi-part processing, assembly and gluing in traditional packaging, shortening the production cycle and reducing labor costs.

[0023] like Figure 1 As shown, it also includes a cover 10, which is sleeved on the outside of the base plate 1 and the flip cover 7. Specifically, when the flip cover 7 is fastened to the rib 2 by the first protrusion 8 and the first recess 9, the cover 10 can be tightly sleeved on the outside of the base plate 1 and the flip cover 7, forming a secondary lock, thereby restricting the opening and closing of the flip cover 7 and preventing the flip cover 7 from popping open due to external forces such as transportation vibration.

[0024] like Figure 1 As shown, the envelope 10 is provided with a virtual break line 11. Specifically, the virtual break line 11 forms a weakened structure on the envelope 10, which can be opened by simply tearing, thus improving the portability of use.

[0025] like Figure 2As shown, one end of the receiving cavity 3 is provided with an opening 12. The opening 12 breaks the closed ring structure of the rib 2 to form a partial opening, so that the phone case can be removed from the mold 4 when in use. The flip cover 7 is provided with a sealing block 13 corresponding to the opening 12. Its shape matches the outline of the opening 12. When the flip cover 7 is closed, the sealing block 13 is embedded in the opening 12, and together with the rest of the rib 2, it forms a closed receiving space, which not only retains the supporting and protective function of the rib 2, but also makes it easy to remove the phone case from the mold 4 when the flip cover 7 is opened.

[0026] like Figure 2 As shown, a second protrusion 14 is provided on the substrate 1 at the opening 12, and a second recess 15 corresponding to the second protrusion 14 is provided on the sealing block 13. Specifically, when the sealing block 13 is inserted into the opening 12, the second protrusion 14 and the second recess 15 form a precise fit, which forms an additional lock on the opening 12 area when the flip cover 7 is in the closed state, effectively enhancing the connection strength between the sealing block 13 and the substrate 1, and preventing the sealing block 13 from falling off the opening 12 due to vibration or external force.

[0027] like Figure 1 , Figure 2 As shown, one end of the substrate 1 is provided with a hook 16. Specifically, the hook 16 enables the packaging box to be hung on shelves, display racks, and other similar locations.

[0028] like Figure 2 As shown, the flip cover 7 is provided with reinforcing ribs 17 on both sides. Specifically, the reinforcing ribs 17 extend along the length of the flip cover 7 to form a strip-shaped protrusion structure, which enhances the flip cover 7's resistance to bending, prevents deformation of the middle part caused by frequent opening and closing or external pressure, and ensures the fastening accuracy of the first protrusion 8 and the first recess 9.

[0029] In practical use, the inner surface of the phone case is aligned with the protrusion 4 in the middle of the receiving cavity 3, which is adapted to the contour of the case, and then inserted. The edge of the case is turned inward and locked into the bottom groove 5 of the protrusion 4 to limit displacement and prevent it from falling off during transportation. Then, the flip cover 7 is flipped along the connecting part 6 so that the first protrusion 8 on the lower surface of the flip cover 7 is embedded into the rib 2 and the first recess 9 to form a fastening and locking, preventing the flip cover 7 from popping open. When taking it out, the flip cover 7 is opened and the phone case can be removed from the protrusion 4.

[0030] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
