[0046] The structural principle and working principle of the present invention will be specifically described below in conjunction with the accompanying drawings:

[0047] Refer to Figures 1 - 3 , Figure 1 which is a schematic structural diagram of an embodiment of the present utility model, Figure 2 is Figure 1 the front view of Figure 3 is Figure 2Cross-sectional view of A-A. The foldable and openable packaging box of the present utility model includes: a first box body 1, including a first outer shell 11, a first substrate 14, a substrate bottom layer 12 and a shell surface layer 13. The substrate bottom layer 12 is disposed on the upper surface of the first substrate 14 and is embedded in the first outer shell 11 together with the first substrate 14. The shell surface layer 13 is disposed on the outer surface of the first shell. A display portion 15 for placing a commemorative coin 5 and a first auxiliary portion 16 for setting corresponding explanatory texts or pictures are respectively disposed on the first outer shell 11, the first substrate 14, the substrate bottom layer 12 and the shell surface layer 13; a second box body 2, including a second outer shell 21, a second substrate 22, an elastic bottom frame 23 and a bottom frame surface layer 24. The second substrate 22 is disposed in the elastic bottom frame 23 and is embedded in the second outer shell 21 together with the elastic bottom frame 23. The bottom frame surface layer 24 is disposed on the surface of the second substrate 22 and the elastic bottom frame 23 on the side opposite to the second outer shell 21; a second auxiliary portion 25 for setting a corresponding certificate 6 or picture is disposed on the second outer shell 21; and a pivoting member 3, respectively connected to the first outer shell 11 and the second outer shell 21. The first box body 1 and the second box body 2 are respectively switched between an open position and a folded position through the pivoting member 3.

[0048] See Figures 4 - 6 , Figure 4 is Figure 1 structural schematic diagram of the open position of Figure 5 is Figure 4 cross-sectional view of B-B of Figure 6 is Figure 4 cross-sectional view of C-C of. The display portion 15 of this embodiment is a groove adapted to the shape of the commemorative coin 5, and a positioning member 17 is disposed in the groove. The groove can be set to be circular, rectangular, polygonal, elliptical or irregular according to the shape of the commemorative coin 5. Preferably, the positioning member 17 is a silicone rubber sealing ring. The first auxiliary portion 16 and the second auxiliary portion 25 are respectively preferably rectangular grooves, and the explanatory text, certificate 6 or picture are disposed on a label 7, a printing coating or a printing layer in the rectangular groove. The first auxiliary portion 16 can be a rectangular groove, and the second auxiliary portion 25 can be set to be a square groove corresponding to the shape of the certificate 6.

[0049] The first outer shell 11 and the second outer shell 21 of this embodiment are both metal outer shells. Preferably, they are 6061 aluminum plate material parts, with a hardness of 90-95 HB and a pressure resistance of 124 MPA. Their compressive capacity can play a better protective role for the commemorative coin 5. The folding and opening can be completed by a hinge, which is foldable, can be placed, and can be opened and closed smoothly, improving the fun of appreciation.

[0050] The first substrate 14 and the second substrate 22 are preferably acrylic material parts. The collection certificate 6 is the identity proof of this commemorative coin 5. Each coin comes with one certificate and it is non-renewable. Both the first substrate 14 and the second substrate 22 can be two layers up and down. The commemorative coin 5, label 7 or certificate 6, etc. are respectively sandwiched between the two layers of the first substrate 14 or the second substrate 22. Both the first substrate 14 and the second substrate 22 are made of high-definition acrylic monomer material, with high transparency. The transparency can be measured to be over 95 by a solar film tester. The degree of UV resistance can reach 20%. It is not easy to turn yellow in an indoor environment, ensuring the clear visibility of the commemorative coin 5 and collection certificate 6. Moreover, it is an environmentally friendly material, which can prevent the commemorative coin 5 from suffering multiple damages caused by environmental factors and the corrosion of the packaging material itself. The hardness is 2H, flat and not easy to deform, which can provide good protection for the commemorative coin 5 and collection certificate 6. The silicone sealing ring for positioning can prevent the precious metal commemorative coin 5 from shaking and rotating in the hole. It is made of environmentally friendly plastic, with the main component being silicon dioxide. It has stable chemical properties, is non-toxic and odorless, and can well protect the commemorative coin 5 from being eroded, playing a protective role for the precious metal.

[0051] The bottom layer 12 of the substrate, the surface layer 13 of the shell and the surface layer 24 of the bottom frame are all preferably PVC film layers that can be customized for printing. The ink coating of the PVC film layer preferably uses environmentally friendly hard ink with medium to high strength adhesion. It has strong adhesion and is not easy to fall off. Patterns can be customized for printing, increasing the versatility of the same type of metal packaging box. The ink coating can be printed using a UV8-color printer, with more delicate and natural colors. The nozzle is a magnetic levitation nozzle, avoiding the static electricity generated during friction, thus accelerating the production speed.

[0052] The hinge 3 is a hinge provided on one side of the first outer shell 11 and the second outer shell 21. In this embodiment, a buckle 4 can also be included, which is provided on the side of the first outer shell 11 and the second outer shell 21 opposite to the hinge for easy opening. The buckle 4 can be a groove or protrusion symmetrically arranged on the first outer shell 11 and the second outer shell 21, or a snap structure that is respectively arranged on the first outer shell 11 and the second outer shell 21 and is mutually adapted, or a flange provided on the first outer shell 11 and a groove provided on the second outer shell 21, as long as it has the function of facilitating opening and closing, and there is no limit to its specific structure. The elastic bottom frame 23 is preferably made of black Eva (Ethylene Vinyl Acetate Copolymer) material. The Eva material has good elasticity and can play a buffering role during impact. It is arranged outside the high-definition acrylic substrate and can also prevent the displacement of the high-definition acrylic substrate.

[0053] The encapsulation box of the present utility model is protected by a metal frame and can be folded open and closed, which not only facilitates the collection of commemorative coins 5, but also provides comprehensive protection. The opening and closing structure also gives greater freedom to the storage space. It can be folded, placed, and smoothly opened and closed, enhancing the fun of collection and appreciation.

[0054] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
