[0031] It should be clear that the paper-plastic outer box 10 and the paper-plastic inner tray 20 refer to an outer box and an inner tray formed by a paper-plastic process, which is a pulp molding process, which is a process of using pulp material as raw material to form a paper product of a certain shape by extrusion on a specific mold. In this embodiment, the outer box and the inner tray of the packaging box are both formed by the paper-plastic process, which can effectively reduce the production cost of the packaging box and improve the environmental performance of the packaging box compared to the packaging box made of metal, plastic or leather.

[0032] Specifically, the paper plastic outer box 10 includes a box body 11 and a box cover 12, a first receiving groove 13 is formed on the box body 11, a second receiving groove 14 is formed on the box cover 12, and the paper plastic inner tray 20 includes a first inner tray portion 21 and a second inner tray portion 22, the first inner tray portion 21 is arranged in the first receiving groove 13, and the second inner tray portion 22 is arranged in the second receiving groove 14, and the first inner tray portion 21 and the second inner tray portion 22 are both formed with a storage groove 23. When the box body 11 and the box cover 12 are closed, the first inner tray portion 21 The first inner support part 21 and the second inner support part 22 are mutually attached under the action of the box body 11 and the box cover 12, and the storage groove 23 of the first inner support part 21 and the storage groove 23 of the second inner support part 22 are aligned to form a storage cavity for accommodating items. When the box body 11 and the box cover 12 are opened, the first inner support part 21 and the second inner support part 22 are separated under the action of the box body 11 and the box cover 12, and the surface of the first inner support part 21 formed with the storage groove 23 and the surface of the second inner support part 22 formed with the storage groove 23 are exposed to the outside. It can be understood that in the outer box, the box body 11 and the box cover 12 can be connected to each other and can be opened and closed, or the box body 11 and the box cover 12 can also be separated from each other, which is not limited in this embodiment. Moreover, in the paper-molded inner support 20, the first inner support part 21 and the second inner support part 22 can be connected to each other or separated from each other, which is not limited in this embodiment. Optionally, the outer shape of the paper-plastic outer box 10 can be reasonably set according to actual conditions. For example, the paper-plastic outer box 10 can be set to a lotus leaf shape to improve the aesthetics.

[0033] In the paper-plastic packaging box provided in the embodiment of the present application, the paper-plastic outer box 10 includes a box body 11 and a box cover 12, the box body 11 is provided with a first receiving groove 13, the box cover 12 is provided with a second receiving groove 14, and the paper-plastic inner support 20 includes a first inner support portion 21 provided in the first receiving groove 13 and a second inner support portion 22 provided in the second receiving groove 14, and the first inner support portion 21 and the second inner support portion 22 are respectively formed with a storage groove 23, when the box body 11 and the box cover 12 are closed, the storage groove 23 of the first inner support portion 21 and the storage groove 23 of the second inner support portion 22 are enclosed to form a storage cavity, so that the articles can be accommodated and the articles are limited to prevent the articles from being damaged during transportation.

[0053] Please continue to refer to Figure 4 According to the first aspect of the embodiment of the present application, the first accommodating groove 13 includes a first bottom wall 131, the first inner supporting portion 21 includes a first fitting surface 213 for fitting with the second inner supporting portion 22, and the first fitting surface 213 is inclined relative to the first bottom wall 131; the second accommodating groove 14 includes a second bottom wall 141, the second inner supporting portion 22 includes a second fitting surface 223 for fitting with the first inner supporting portion 21, and the second fitting surface 223 is inclined relative to the second bottom wall 141.

[0054] The first receiving groove 13 further includes a first side wall 132 disposed around the circumference of the first bottom wall 131, the first opening of the first receiving groove 13 is disposed opposite to the first bottom wall 131, the first inner support portion 21 is disposed in the first receiving groove 13, and the first contact surface 213 of the second inner support portion 22 is disposed near the first opening. The second receiving groove 14 further includes a second side wall 142 disposed around the circumference of the second bottom wall 141, the second opening of the second receiving groove 14 is disposed opposite to the second bottom wall 141, the second inner support portion 22 is disposed in the second receiving groove 14, and the second contact surface 223 of the first inner support portion 21 is disposed near the second opening. The storage groove 23 of the first inner supporting part 21 is formed on the first fitting surface 213, and the storage groove 23 of the second inner supporting part 22 is formed on the second fitting surface 223. When the box body 11 and the box cover 12 are closed, the first fitting surface 213 of the first inner supporting part 21 fits with the second fitting surface 223 of the second inner supporting part 22, and the storage grooves 23 of the two are aligned with each other and enclosed to form a storage cavity.

[0055] In this embodiment, the first fitting surface 213 is inclined relative to the first bottom wall 131, and the second fitting surface 223 is inclined relative to the second bottom wall 141. Therefore, when the box body 11 and the box cover 12 are closed, the first fitting surface 213 can fit with the second fitting surface 223. At the same time, during the processing of the first inner support portion 21 and the second inner support portion 22, the demolding difficulty of the first inner support portion 21 and the second inner support portion 22 can be reduced, thereby improving the production efficiency.

[0056] It should be clarified that when the box body 11 and the box cover 12 are opened, the inclination direction of the first fitting surface 213 relative to the first bottom wall 131 is the same as the inclination direction of the second fitting surface 223 relative to the second bottom wall 141; when the box body 11 and the box cover 12 are closed, the inclination direction of the first fitting surface 213 relative to the first bottom wall 131 is opposite to the inclination direction of the second fitting surface 223 relative to the second bottom wall 141, thereby ensuring that the first fitting surface 213 and the second fitting surface 223 can be tightly arranged when the box body 11 and the box cover 12 are closed.

[0057] Please continue to refer to Figure 4 According to a first aspect of the embodiment of the present application, at least one of the box body 11 and the box cover 12 includes a main body 15 and a handle 16 arranged on the main body 15, and the main body 15 is formed with a first accommodating groove 13 or a second accommodating groove 14.

[0058] When the box body 11 includes a main body 15 and a handle 16 , the main body 15 of the box body 11 forms a first receiving groove 13 . When the box cover 12 includes a main body 15 and a handle 16 , the main body 15 of the box cover 12 forms a second receiving groove 14 .

[0059] In this embodiment, by providing the handle 16 on at least one of the box body 11 and the box cover 12, there is no need to pack the paper-plastic packaging box with an additional packaging bag, which can reduce the packaging cost. At the same time, directly providing the handle 16 on the paper-plastic packaging box can also improve the stability of the handle 16.

[0060] Optionally, when the box body 11 and the box cover 12 both have a handle 16, the handles 16 of the two can be arranged close to each other. If the box body 11 and the box cover 12 are closed, the handle 16 of the box body 11 can be arranged in close contact with the handle 16 of the box cover 12 for easy use.

[0061] Furthermore, a first groove is formed on the handle portion 16 of the box body 11, and a second groove is formed on the handle portion 16 of the box cover 12. When the box body 11 and the box cover 12 are closed and the handle portions 16 of the two are attached, the first groove and the second groove are aligned and enclosed to form a cavity, thereby reducing the weight of the paper-plastic packaging box.

[0062] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
