[0039] With the continuous development of the economy, people's consumption concepts are also constantly changing. As a product, packaging is a summary of brand concepts, product characteristics and consumer psychology, and its status in commodity production is constantly improving. Novel and unique packaging will immediately catch the attention of consumers in the market, arouse their curiosity, and attract them to buy and try. It can not only increase consumers' desire to buy, but also improve the competitiveness of products among similar products, increase consumers' purchasing stickiness, and is conducive to the long-term development of the brand.

[0040] In order to improve the fun of the packaging box and provide a new way to take the product, the present application provides a packaging box. Figures 1 to 10 The attaching device of the embodiment of the present application is described in detail. It should be noted that the material of the packaging box provided in the embodiment of the present application is not specified here, and optionally, the packaging box includes paper material, or the packaging box includes plastic material or metal material.

Figure 2 This is a schematic diagram of the second box body of the packaging box provided in the first embodiment of the present application. Figure 3 This is a schematic structural diagram of the packaging box provided in the first embodiment of the present application in a closed state. Figure 4 A schematic diagram of the structure of the packaging box provided in the first embodiment of the present application in an open state. Figure 5 Another schematic diagram of the structure of the packaging box provided in the first embodiment of the present application in an open state. Figure 6 This is another structural schematic diagram of the packaging box provided in the first embodiment of the present application in an open state.

[0042] like Figures 1 to 6As shown, the present application provides a packaging box, which has a closed state and an open state, and includes at least three first box bodies 1 and at least one second box body 2, the first box bodies 1 are connected end to end in sequence, and each first box body 1 includes a first accommodating cavity 13 located inside, and a first opening 11 arranged at the head end and connected to the first accommodating cavity 13; at least part of the structure of each second box body 2 is located in the first accommodating cavity 13 of a first box body 1, and is connected to another adjacent first box body 1 through the first opening 11; in the process of the packaging box changing from a closed state to an open state, at least two adjacent first box bodies 1 gradually move away from each other, and drive the second box body 2 to gradually extend out of the corresponding first accommodating cavity 13 from the corresponding first opening 11.

[0043] The first box bodies 1 are connected end to end in sequence to make the entire packaging box centrally symmetrical. It should be noted that the specific number of the first box bodies 1 is not specified here, and it is only necessary to satisfy that at least three first box bodies 1 are provided and each first box body 1 is connected end to end in sequence. Optionally, the number of the first box bodies 1 can be three, four or six. The shape of the first box body 1 can be determined according to the adaptability of the number of the first box bodies 1. For example, when the number of the first box bodies 1 is three, the first box body 1 can be set to a triangle or a trapezoid. When the number of the first box bodies 1 is four or six, the first box body 1 can be set to a rectangle.

[0044] Each first box body 1 includes a first opening 11 disposed at a head end and communicating with the first accommodating cavity 13, wherein the head end refers to a side wall of each first box body 1 abutting against an adjacent first box body 1 in a circumferential direction, and the circumferential direction can be either clockwise or counterclockwise. Figure 3 As shown, when the circling direction is counterclockwise, the first box body 1 located in the upper left corner of the figure is the adjacent box body of the first box body 1 located in the upper right corner of the figure in the circling direction, then the side wall of the first box body 1 located in the upper right corner of the figure close to the adjacent box body is the head end, similarly, the side wall of the first box body 1 located in the upper left corner of the figure close to its adjacent box body in the counterclockwise direction is also the head end. The first opening 11 is a hole-shaped structure arranged on the head end of each first box body 1, and the first opening 11 runs through the head end along the thickness direction of the side wall. The first opening 11 not only connects the first accommodating cavity 13 with the first box body 1, provides an outlet for the second box body 2 to slide out, but also provides a limiting effect for the second box body 2. The first opening 11 has a variety of shapes and sizes, which can be determined according to the size of the second box body 2. Optionally, the size of the first opening 11 is equal to the size of the side wall surface of the head end of the first box body 1. In this case, the size of the first opening 11 is the largest, which can make the sliding track of the second box body 2 stable, and it is not easy to intersect with other second boxes 2, thereby causing the packaging box to be opened and closed.

[0045] Each first box body 1 includes a first accommodating cavity 13 located inside, and at least part of the structure of each second box body 2 is located in the first accommodating cavity 13 of a first box body 1. The second box body 2 is used to place the packaged object. Optionally, the number of the second box bodies 2 can be one or more, and each first accommodating cavity 13 can accommodate one second box body 2 or multiple second box bodies 2. Optionally, the second box body 2 is entirely located in the first accommodating cavity 13, or part of the structure of the second box body 2 is located in the first accommodating cavity 13.

[0046] The packaging box has a closed state, in which the first box bodies 1 abut against each other and each first box body 1 has two common side walls with the adjacent first box bodies 1, namely the head end and the tail end mentioned above, and the second box body 2 is located inside the first box body 1, so as to avoid being exposed to the outside by the package. For example, Figure 5 As shown, the packaging box includes four first box bodies 1, and a second box body 2 is disposed in the first accommodating cavity 13 of each first box body 1, and the four first box bodies 1 are disposed end to end. The opening state of the packaging box includes various forms. In some embodiments, the packaging box can be partially opened to take out the packaged items in part of the first box body 1, and ensure that the packaged items in the remaining first box bodies 1 are not in contact with the outside world to avoid contamination or damage. Take the example of four first box bodies 1, as shown in FIG. Figure 4 and Figure 5 As shown, two first box bodies 1 arranged side by side gradually move away from the other two first box bodies 1 arranged side by side in the same direction, and the second box body 2 gradually leaves the corresponding first accommodating cavity 13 under the traction of the first box body 1, so that the user can take the packaged items in the second box body 2; in some other embodiments, the packaging box can be completely opened, and all the packaged items in the packaging box can be seen. For example, four first box bodies 1 are provided, such as Figure 6 As shown, any two adjacent first boxes 1 are gradually separated and spaced apart, and the first box 1 drives each second box 2 to leave the corresponding first accommodating cavity 13 from the corresponding first opening 11, so that all the packaged items in the second box 2 are exposed to the outside for easy selection and taking.

[0047] The packaging box has a unique structure and opening method, which can not only provide protection and sealing for the packaged items, but also increase the aesthetics and interest of the packaging box itself, add added value to the product, make the product recognizable, improve the interaction and ritual sense between consumers and products, and increase the attractiveness of the product, stimulate consumers' purchasing interest and desire, and thus increase product sales and competitiveness. In addition, the packaging box is also practical and can ensure the safe isolation of the packaged items inside. The packaging box can also be reused, providing consumers with more use value.

[0048] Furthermore, in some embodiments, in order to facilitate taking out the packaged items in the packaging box, the second box body 2 includes a second accommodating cavity 27 located inside and a first surface in the first direction X, and a third opening connected to the second accommodating cavity 27 is provided on the first surface; the first direction X intersects with the moving direction of the second box body 2.

[0049] The third opening provides a way to display the packaged items. By changing the degree of opening of the packaging box, the packaged items can be displayed in different ways, thereby increasing the added value of the packaged items. It should be noted that the packaged items can be products with collection attributes such as jewelry and cosmetics, or they can also be products such as food.

[0050] Furthermore, in some embodiments, the rear end of each first box body 1 is provided with a second opening 12 connected to the first accommodating cavity 13, and when the packaging box is in a closed state, at least one second box body 2 is located in two adjacent first accommodating cavities 13 through the first opening 11 and the second opening 12.

[0051] like Figure 5 As shown, the tail end of each first box body 1 is provided with a second opening 12 communicating with the first accommodating cavity 13, wherein the tail end is the side wall of each first box body 1 abutting against the adjacent first box body 1 in the reverse circumferential direction, the circumferential direction can be either clockwise or counterclockwise, and the tail end and the head end are two adjacent side walls on the first box body 1. For example, Figure 3 As shown, when the winding direction is counterclockwise, the first box body 1 located at the lower right corner of the figure is the adjacent box body of the first box body 1 located at the upper right corner of the figure in the reverse winding direction, and the side wall of the first box body 1 located at the upper right corner of the figure and the adjacent box body is the tail end. The second opening 12 is a hole-like structure provided on the tail end of each first box body 1, and the second opening 12 runs through the tail end along the thickness direction of the side wall. The second opening 12 has a variety of shapes and sizes, which can be determined according to the size of the second box body 2. Optionally, the size of the second opening 12 is equal to the size of the side wall of the tail end of the first box body 1. In this case, the size of the second opening 12 is the largest, which can stabilize the sliding track of the second box body 2 and is not easy to be staggered with other second box bodies 2, thereby causing the packaging box to be stuck in opening and closing.

[0052] By providing the second opening 12, two adjacent first box bodies 1 can be connected, so that when the packaging box is in a closed state, at least one second box body 2 is located in two adjacent first accommodating cavities 13 through the first opening 11 and the second opening 12, and the plurality of second box bodies 2 are centrally symmetrical. By providing the second box body 2 in two adjacent first accommodating cavities 13, not only the size of the second box body 2 is increased, but also the edge of the second box body 2 can be hidden in the first box body 1, thereby improving the neatness and beauty of the packaging box.

[0054] In order to prevent the second box body 2 from slipping off the first box body 1, in some embodiments, the first box body 1 includes a first inner wall surface 14 adjacent to the head end, and a first limiting structure is arranged on the first inner wall surface 14; the second box body 2 includes a first outer wall surface 21 parallel to the first inner wall surface 14, and a second limiting structure cooperating with the first limiting structure is arranged on the first outer wall surface 21.

[0055] The first box body 1 includes a first inner wall surface 14 adjacent to the head end, and the second box body 2 includes a first outer wall surface 21 parallel to the first inner wall surface 14. A first limiting structure is arranged on the first inner wall surface 14, and a second limiting structure cooperating with the first limiting structure is arranged on the first outer wall surface 21. Among them, the first inner wall surface 14 is a wall surface adjacent to the side wall of the head end, the first box body 1 has a plurality of first inner wall surfaces 14, and the first limiting structure is arranged on at least one first inner wall surface 14. Similarly, the second box body 2 also has a plurality of first outer wall surfaces 21, and the second limiting structure is arranged on at least one first outer wall surface 21. It should be noted that the first limiting structure and the second limiting structure can be arranged on any first inner wall surface 14 and first outer wall surface 21, as long as the first inner wall surface 14 and the first outer wall surface 21 are parallel, and the first limiting structure and the second limiting structure can cooperate with each other.

[0056] The first limiting structure and the second limiting structure can have various forms. Optionally, the first limiting structure and the second limiting structure respectively include a stopper protruding from the first inner wall surface 14 and a stopper protruding from the first outer wall surface 21. The stopper protruding from the first inner wall surface 14 blocks the stopper protruding from the first outer wall surface 21 to prevent the second box body 2 from sliding out of the first box body 1.

[0057] In some embodiments, the first limiting structure includes a first bending portion 15 connected to the first inner wall surface 14, and the first bending portion 15 is bent from a direction pointing to the first opening 11 to a direction away from the first opening 11; the second limiting structure includes a second bending portion 22 connected to the first outer wall surface 21, and the second bending portion 22 is located on the side of the first bending portion 15 away from the first opening 11 in the sliding direction of the second box body 2, and the second bending portion 22 is bent from a direction away from the first opening 11 to a direction pointing to the first opening 11.

[0058] like Figures 7 to 10As shown, in the process of the packaging box changing from a closed state to an open state, the second box body 2 gradually moves out of the first accommodating cavity 13 along the sliding direction, and the first bent portion 15 is hooked with the second bent portion 22 to prevent the second box body 2 from continuing to move, thereby realizing the limiting effect of the first limiting structure on the second box body 2 in the sliding direction. It should be noted that the first bent portion 15 can be set at any position on the first inner wall surface 14, and the second bent portion 22 can be set at any position on the first outer wall surface 21, as long as the second bent portion 22 is located on the side of the first bent portion 15 away from the first opening 11 in the sliding direction.

[0059] In order to improve the connection stability between the first bending portion 15 and the first inner wall surface 14, further optionally, the first limiting structure also includes a first connecting portion 16, the first connecting portion 16 is connected to the first inner wall surface 14, and the first bending portion 15 is connected to the first inner wall surface 14 through the first connecting portion 16. Further optionally, the angle between the first bending portion 15 and the first connecting portion 16 is an acute angle to avoid the first limiting structure and the second limiting structure occupying the space of the first accommodating cavity. Similarly, optionally, the second limiting structure also includes a second connecting portion 23, the second connecting portion 23 is connected to the first outer wall surface 21, and the second bending portion 22 is connected to the first outer wall surface 21 through the second connecting portion 23. Further optionally, the angle between the second bending portion 22 and the second connecting portion 23 is an acute angle. It should be noted that the first connecting portion 16 and the first bending portion 15 can be integrally arranged or separately arranged, and the second connecting portion 23 and the second bending portion 22 can be integrally arranged or separately arranged.

[0060] In order to achieve the traction effect of the first box body 1 on the second box body 2 in the adjacent first box body 1, in some embodiments, the first box body 1 includes a second inner wall surface 17 adjacent to the tail end, and a first connecting structure is provided on the second inner wall surface 17, and a second connecting structure that cooperates with the first connecting structure of the adjacent first box body 1 is provided on the first outer wall surface 21.

[0061] The first box body 1 includes a second inner wall surface 17 adjacent to the rear end, and a first connecting structure is arranged on the second inner wall surface 17, wherein a portion of the second inner wall surface 17 belongs to the first inner wall surface 14 mentioned above, that is, the first connecting structure and the first limiting structure can be arranged on different inner wall surfaces, or on inner wall surfaces belonging to both the first inner wall surface 14 and the second inner wall surface 17. It should be noted that the first box body 1 has a plurality of second inner wall surfaces 17, and the first connecting structure is arranged on at least one second inner wall surface 17, and similarly, the second connecting structure is arranged on at least one first outer wall surface 21.

[0062] The first connection structure and the second connection structure can have various forms. Optionally, the second inner wall surface 17 is directly adhered to the first outer wall surface 21, or the first connection structure and the second connection structure include magnetic structures 141, and the connection between the first box body 1 and the second box body 2 is achieved through the interaction force between the magnetic structures 141.
