DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0026] like Figures 1 to 7 As shown, a sealed anti-tampering packaging box includes a first blister box body 6, a second blister box body 7, a first paperboard 1, and a second paperboard 5. In the present application, the first blister box body 6 and the second blister box body 7 are both made of PET material and can be reused. The first blister box body 6 and the second blister box body 7 can also be made of other materials according to actual needs, such as polypropylene (PP).

[0027] A first flange structure 8 is provided at the opening edge of the first blister box body 6, and a second flange structure 9 is provided at the opening edge of the second blister box body 7. The first flange structure 8 is a circular ring structure provided at the opening edge of the first blister box body 6 and protruding along the radial outer side of the first blister box body 6, and the second flange structure 9 is a circular ring structure provided at the opening edge of the second blister box body 7 and protruding along the radial outer side of the second blister box body 7. The first blister box body 6 and the second blister box body 7 are buckled with each other. After the first blister box body 6 and the second blister box body 7 are buckled, the first flange structure 8 and the second flange structure 9 are fitted, and a storage space for placing the product 10 is formed between the first blister box body 6 and the second blister box body 7.

[0028] The second paperboard 5 is provided with a first hollow area through which the first blister box body 6 can pass, and the first paperboard 1 is provided with a second hollow area corresponding to the first hollow area. The second paperboard 5 is arranged on the first paperboard 1, and the first flange structure 8 and the second flange structure 9 are sandwiched between the first paperboard and the second paperboard 5. Among them, the second paperboard 5 and the first paperboard are bonded by glue, and the two are combined by glue hot pressing process. The specific operation is: first apply hot pressing glue on the first paperboard, put the product 10 (lunch paper tray) into the first blister box body 6 and the second blister box body 7, and then buckle the two, then place the first flange structure 8 on the first box body and the second flange structure 9 on the second box body between the first paperboard and the second paperboard 5, and then attach the second paperboard 5 to the first paperboard and perform hot pressing, so that the first paperboard and the second paperboard 5 are closely bonded together after hot pressing, and the first flange structure 8 and the second flange structure 9 are also pressed at the same time.

[0029] The area of ​​the first paperboard is larger than that of the second paperboard 5. A portion of the first paperboard is a bonding area. The second paperboard 5 is bonded to the bonding area of ​​the first paperboard. Another portion of the first paperboard is a bendable area. A bending line 3 is provided between the bendable area and the bonding area. The bendable area is bent along the bending line. The bending line 3 is a straight line indentation. The strength at this location is relatively weak, making it most likely to bend. A hanging hole 4 is provided on the bendable area. During transportation, in order to save space, the bendable area on the first paperboard can be folded along the bending line 3 to reduce the space occupied by the entire packaging structure.

[0030] The first paperboard and the second paperboard 5 are both provided with a tearing line 2 for facilitating tearing the first paperboard or the second paperboard 5, and the tearing line 2 on the first paperboard corresponds to the tearing line 2 on the second paperboard 5. The tearing line 2 is aligned with the middle position of the first blister box body 6 and the second blister box body 7. A series of holes are arranged on the tearing line 2, so that the structural strength at the position of the tearing line 2 is the weakest, which is convenient for tearing the first paperboard and the second paperboard 5 and realizing the opening of the entire packaging structure. The utility model uses a destructive opening method for the packaging, and once the packaging is opened, it cannot be restored, thus avoiding the possibility of malicious replacement of the product 10 in the packaging.

[0031] Furthermore, it also includes an auxiliary clip 11, which is clamped at the position of the tear line. The auxiliary clip includes a C-shaped elastic body 12, and clips 13 are respectively provided at both ends of the C-shaped elastic body 12. The end of the clip 13 away from the C-shaped elastic body 12 is provided with a folding portion 14, and the clip 13 is integrally formed with the C-shaped elastic body. A stamping portion 16 is respectively provided on both sides of one of the clips 13, and the stamping portion 16 is bent toward the direction of the other clip 13. The stamping portion 16 is formed by stamping, and after the stamping portion 16 is stamped on the clip 13, a punching groove 15 is left at the position of the stamping portion 16. When the auxiliary clip 11 is clamped at the position of the tear line, the stamping portions on the clip are respectively located on both sides of the tear line 2. In this embodiment, the auxiliary clip 11 is made of spring steel.

[0032] Since the structural strength at the tear line 2 is the weakest, the tear line 2 is easily bent repeatedly due to various external forces during long-term transportation or storage, so that the tear line 2 is easily broken, which in turn causes the entire packaging box to be damaged, reducing the sealing of the packaging box. In view of the above reasons, the utility model installs an auxiliary clip 11 at the tear line 2, and the auxiliary clip 11 is clamped on the tear line 2. The two sides of the tear line 2 are clamped by the clips 13 on both sides of the auxiliary clip 11 to prevent the tear line 2 from bending due to external forces during transportation or storage; wherein, after the auxiliary clip 11 is clamped on the tear line 2, the clips 13 on both sides are pressed to make the stamping part 16 on the clips 13 embedded in the first paperboard or the second paperboard, which effectively improves the connection strength between the auxiliary clip 11 and the paperboard and prevents the auxiliary clip 11 from falling off; when the packaging box needs to be disassembled, it is only necessary to remove the auxiliary clip 11 and then tear the paperboard from the tear line 2. When removing the auxiliary clip 11, the folding portion 14 on the clip 13 with the punching portion can be appropriately lifted to keep the punching portion 16 on the clip 13 away from the paperboard, and then the auxiliary clip can be easily removed from the paperboard by sliding it toward the outside of the paperboard.

[0033] The utility model has good sealing performance, reduces the probability of the product 10 being contaminated during transportation, and is conducive to meeting the epidemic prevention and quarantine requirements of the product 10; and the utility model uses a hard first blister box body 6 and a second blister box body 7 to package the product 10, and the first blister box body 6 and the second blister box body 7 have a good supporting and protective effect on the internal product 10, which can effectively reduce the possibility of the product 10 being crushed during transportation. The first blister box body 6 and the second blister box body 7 can be reused, reducing material waste.

[0034] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
