These drawings and the accompanying text are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of this application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0068] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0069] It should be noted that, in the present document, relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0070] In the field of modern product design, most products need to be designed with packaging boxes. Paper material packaging boxes not only can realize recycling and reduce environmental impact, but also are light in weight and do not add too much weight, which is convenient for users to carry. Therefore, paper packaging boxes are widely used in many fields.

[0071] However, the paper material packaging box is usually formed by folding. Since the paper material is usually a fiber material, the fibers in the paper will elastically deform when subjected to the stress generated by folding. When the external force is removed, the fibers tend to return to the original shape, so that the paper packaging box formed by folding is easy to open, which affects the packaging stability of the packaging box.

[0072] In view of this, in a first aspect, please refer to Figures 1-2The embodiment of the present application provides a packaging box 100. The packaging box 100 comprises a bottom plate 10, a first enclosing part 20, a second enclosing part 30 and a first stopper 40, the bottom plate 10 has a first edge 11 extending along a second direction Y and a second edge 12 extending along a first direction X, the first direction X, the second direction Y and the thickness direction Z of the bottom plate 10 intersect with each other in pairs. The first enclosing part 20 comprises a first side wall 21 and a first top wall 22 connected integrally, the first side wall 21 is connected to the first edge 11 by bending, and the first top wall 22 is connected to the first side wall 21 by bending and is arranged opposite to the bottom plate 10 in the thickness direction Z. The second enclosing part 30 comprises a second side wall 31 and a second top wall 32 connected integrally, the second side wall 31 is connected to the second edge 12 by bending, and the second top wall 32 is connected to the second side wall 31 by bending and is arranged opposite to the bottom plate 10 in the thickness direction Z. The first stopper 40 is detachably connected to the second top wall 32. The first top wall 22 is located on the side of the second top wall 32 facing the bottom plate 10, the first top walls 22 of the two first enclosing parts 20 are adjacent to each other along the first direction X away from one end of the first side wall 21, and the first stopper 40 is located on the side of the first side wall 22 away from the bottom plate 10 in the thickness direction Z to generate a pressing effect on the first side wall 22.

[0073] The packaging box 100 provided by the embodiment of the present application is packaged outside the to-be-packaged part, and the to-be-packaged part is wrapped and closed to realize protection of the to-be-packaged part. The to-be-packaged part can be directly an article that needs to be packaged, and the packaging box 100 provided by the embodiment of the present application is directly packaged outside the article, or the to-be-packaged part can be a packaging inner box that is preliminarily packaged, and the packaging box 100 provided by the embodiment of the present application is used as a packaging outer box to package and protect the packaging inner box.

[0074] The packaging box 100 provided by the embodiment of the present application is not limited in shape, and can be a regular quadrangular prism, for example, the bottom surface of the quadrangular prism is a rectangle, a square or a trapezoid; or can be an irregular packaging body, as long as the corresponding packaging structure has edges and surfaces that need to be packaged, and can be applied to the packaging box 100 provided by the embodiment of the present application.

[0075] For convenience of description and distinction, the packaging box 100 formed by a cuboid is described and introduced herein, and those skilled in the art can apply the structure mentioned in the packaging box 100 to other shapes of packaging box 100, which all belong to the packaging box 100 disclosed by the present application.

[0076] Specifically, the packaging box 100 comprises a bottom plate 10 having a first edge 11 extending along a second direction Y, the bottom plate 10 is connected with a first enclosing part 20 at the first edge 11, wherein the first enclosing part 20 comprises a first side wall 21 and a first top wall 22. The bottom plate 10 is connected with the first side wall 21 by bending, the first side wall 21 is connected with the first top wall 22 by bending, and the first top wall 22 is arranged opposite to the bottom plate 10 along a thickness direction Z of the bottom plate 10. It can be understood that, corresponding to the cuboid structure, the second direction Y can correspond to the length direction of the cuboid, the thickness direction Z of the bottom plate 10 can correspond to the height direction of the cuboid, the bottom plate 10 serves as the bottom surface of the cuboid structure, the cuboid structure has two side surfaces, one of which corresponds to the first side wall 21, and part of the top surface of the cuboid structure corresponds to the first top wall 22.

[0077] The bottom plate 10 has a second edge 12 extending along a first direction X, and the bottom plate 10 is connected with a second enclosing part 30 at the second edge 12, wherein the second enclosing part 30 comprises a second side wall 31 and a second top wall 32. The bottom plate 10 is connected with the second side wall 31 by bending, the second side wall 31 is connected with the second top wall 32 by bending, and the second top wall 32 is arranged opposite to the bottom plate 10 along the thickness direction Z of the bottom plate 10. It can be understood that, corresponding to the cuboid structure, the first direction X can correspond to the width direction of the cuboid, the bottom plate 10 serves as the bottom surface of the cuboid structure, the cuboid structure has two side surfaces, one of which corresponds to the second side wall 31, and part of the top surface of the cuboid structure corresponds to the second top wall 32.

[0078] Optionally, the first enclosing part 20 can be provided as two, the two first side walls 21 in the two first enclosing parts 20 correspond to two side surfaces arranged opposite to each other along the length direction of the cuboid structure respectively, and the two first top walls 22 in the two first enclosing parts 20 cover the top surface of the cuboid structure. Similarly, the second enclosing part 30 can be provided as two, the two second side walls 31 in the two second enclosing parts 30 correspond to two side surfaces arranged opposite to each other along the width direction of the cuboid structure respectively, and the two second top walls 32 in the two second enclosing parts 30 cover the side of the two first top walls 22 away from the bottom plate 10.

[0079] In the embodiment of the present application, the first top wall 22 and the first side wall 21 in the first enclosing part 20 are arranged as an integral structure. On the one hand, this facilitates the production of the packaging box 100, reduces the subsequent process of connecting multiple separate structures, improves the production efficiency of the packaging box 100, and at the same time, reduces the production cost of the packaging box 100. On the other hand, the integral structure of the first enclosing part 20 can form a good sealing packaging at the bending position between the first top wall 22 and the first side wall 21, and provide good protection for the internal structure of the packaging box 100. Further, the first enclosing part 20 and the bottom plate 10 are also integrally formed to form a good sealing packaging at the bending position between the first side wall 21 and the bottom plate 10. For the same reason, the second top wall 32 and the first top wall 31 in the second enclosing part 30 are also arranged as an integral structure, and the second enclosing part 30 and the bottom plate 10 are also arranged as an integral structure, and the beneficial effects thereof will not be repeated here.

[0080] In the embodiment of the present application, the top wall of the packaging box 100 is formed by two first top walls 22 and two second top walls 32. In order to improve the packaging effect of the packaging box 100, the size of the two first top walls 22 in the first direction X is equal to the size of the bottom plate 10 in the first direction X, that is, the area covered by the two first top walls 22 is the area of the top wall, and the two first top walls 22 are adjacently arranged away from one end of the first side wall 21 along the first direction X. Based on the above arrangement, the four edges of the cuboid structure in the length direction are all inside the integral structure of the first enclosing part 20, the bottom plate 10 and the second enclosing part 30, which can ensure the packaging effect of the packaging box 100 on the four edges of the cuboid structure in the length direction. At the same time, the two first top walls 22 cover the top surface of the cuboid structure, which can complete the packaging of the top surface while making the first top wall 22 rotate and bend relative to the first side wall 21 along the second direction Y, and the first side wall 21 rotate and bend relative to the bottom plate 10 along the second direction Y. The bending directions of the above two bending positions are consistent, so that the technician can bend the first side wall 21 and the first top wall 22 along the same rotating direction along the second direction Y during the production process, which is convenient for the production operation of the technician. Further, the two first enclosing parts 20 jointly enclose to form a certain symmetrical structure, which is beneficial to improve the appearance of the packaging box 100.

[0081] After the two first top walls 22 cover the top surface, the second top wall 32 is pressed on the side of the first top wall 22 away from the bottom plate 10 to generate an acting force on the second top wall 32 towards the side of the bottom plate 10, which overcomes the tendency of the second top wall 32 to move away from the side of the bottom plate 10 when it is bent and covers the top surface, thereby improving the stability of the packaging structure of the packaging box 100. At the same time, the second top wall 32 is located outside the first top wall 22, which can also provide a certain protection to the second top wall 32 and reduce the damage to the first top wall 22, so as to ensure the integrity of the packaging of the packaging box 100.

[0082] Since the first top wall 22 and the first side wall 21 are connected by bending, the second top wall 32 and the second side wall 31 are also connected by bending, the second top wall 32 and the first top wall 22 have a tendency to move away from the bottom plate 10 due to bending, and the first stopper 40 is detachably connected to the second top wall 32 to overcome the tendency of the second top wall 32 and the first top wall 22 to move away from the bottom plate 10.

[0083] The first stopper 40 is detachably connected to the second top wall 32, and the first stopper 40 and the second enclosing part 30 are relatively independent structural members without a tendency to move due to previous actions. The first stopper 40 can independently generate a force to overcome the tendency of the second top wall 32 to move away from the bottom plate 10. For the specific connection mode of detachable connection, the first stopper 40 and the second top wall 32 can be bonded or connected by pre-punching.

[0084] Meanwhile, the connection position of the first stopper 40 is on the second top wall 32, which is outside the first top wall 22 and can itself restrain the movement tendency of the first top wall 22. In order to restrain the movement tendency at the source, the first stopper 40 is connected to the second top wall 32, that is, the first stopper 40 restrains the movement tendency of the second top wall 32, and the second top wall 32 restrains the movement tendency of the first top wall 22, thereby ensuring the packaging stability of the first top wall 22 through the superposition of the action level in turn.

[0085] Alternatively, the first stopper 40 can be arranged on the side of the second top wall 32 facing the first top wall 22, and the first stopper 40 is connected to the second top wall 32 and is pressed against the first top wall 22 to ensure the packaging stability of the first top wall 22. Alternatively, the first stopper 40 can be arranged on the side of the second top wall 32 away from the first top wall 22, and the first stopper 40 is connected and pressed against the second top wall 32, and the second top wall 32 is pressed against the first top wall 22 to ensure the packaging stability of the first top wall 22.

[0086] In view of the connection stability between the first stopper 40 and the second top wall 32, it is preferred that the first stopper 40 is arranged on the side of the second top wall 32 away from the first top wall 22. Taking the example of bonding between the first stopper 40 and the second top wall 32, by the above arrangement, the first stopper 40 can be pressed against the second top wall 32 to reduce the tearing force between the first stopper 40 and the second top wall 32, reduce the probability of disconnection between the first stopper 40 and the second top wall 32, and ensure the connection stability between the first stopper 40 and the second top wall 32, thereby ensuring the pressing stability of the second top wall 32 to the first top wall 22 to ensure the packaging stability of the first top wall 22.

[0087] In summary, in the embodiment of the present application, the packaging box 100 comprises the bottom plate 10 and the first enclosing part 20 and the second enclosing part 30 connected to the bottom plate 10 and connected integrally, the first enclosing part 20 is arranged as an integral structure, on the one hand, it is convenient for the production and manufacture of the packaging box 100, reduces the subsequent connecting process of multiple separate structures, improves the production efficiency of the packaging box 100, and at the same time, it also reduces the production cost of the packaging box 100; on the other hand, the integral structure of the first enclosing part 20 can form a packaging with good sealing performance on the bending position between the first side wall 21 and the bottom plate 10 and the bending position between the first top wall 22 and the first side wall 21, and form good protection on the internal structure of the packaging box 100. The second enclosing part 30 is the same. At the same time, the top wall of the packaging box 100 in the embodiment of the present application is formed by two first top walls 22 and two second top walls 32, the two first top walls 22 are adjacent to each other along the first direction X away from one end of the first side wall, and the four edges of the cuboid structure in the length direction are all inside the integral structure of the first enclosing part 20, the bottom plate 10 and the second enclosing part 30, which can ensure the packaging effect of the packaging box 100 on the four edges of the cuboid structure in the length direction, and at the same time, the two first top walls 22 cover the top surface of the cuboid structure, which can complete the packaging of the top surface, and at the same time, the bending direction of the first top wall 22 relative to the first side wall 21 is consistent with the bending direction of the first side wall 21 relative to the bottom plate 10, which is convenient for the production operation of the technician. After the two first top walls 22 form coverage on the top surface, the second top wall 32 is pressed on one side of the first top wall 22 away from the bottom plate 10, so as to generate an acting force on the second top wall 32 towards the side of the bottom plate 10, overcome the tendency of the second top wall 32 moving away from the side of the bottom plate 10 when it is bent and covered on the top surface, and improve the stability of the packaging structure formed by the packaging box 100. Further, the first stopper 40 is detachably connected on the second top wall 32, the first stopper 40 and the second enclosing part 30 are relatively independent structural members, and there is no movement tendency between them due to the previous action, the first stopper 40 can independently generate an acting force to overcome the tendency of the second top wall 32 moving away from the side of the bottom plate 10, so as to make the second top wall 32 restrain the movement tendency of the first top wall 22, and ensure the packaging stability of the first top wall 22 through the above-mentioned way of sequentially superimposing the action levels.

[0088] In some implementable embodiments, please refer to Figures 1-2The first stopper 40 is arranged on the side of the second top wall 32 away from the first top wall 22. The first stopper 40 has a first end D1 and a second end D2 in the first direction X, and the first end D1 is flush with the second end D2 and the two ends of the second top wall 32 in the first direction X. The first stopper 40 has a third end D3 and a fourth end D4 in the second direction Y, and the third end D3 is flush with the second side wall 31, and the fourth end D4 is flush with the end of the second top wall 32 away from the second side wall 31.

[0089] When the first stopper 40 is located on the side of the second top wall 32 away from the first top wall 22, the first stopper 40 is located on the outermost side of the packaging box 100. Through the above arrangement, the first stopper 40 can be flush with the second top wall 32 in the first direction X and the second direction Y, which can press the second top wall 32 on both sides to overcome the movement trend of the second top wall 32 away from the bottom plate 10. On the other hand, the first stopper 40 can also cover the second top wall 32 on both sides, which can protect the second top wall 32 to a certain extent.

[0090] In some implementable embodiments, please refer to Figures 1-2 The middle part of the third end D3 is recessed inward along the second direction Y to form a first notch 41, and the two ends of the fourth end D4 are recessed inward along the second direction Y to form two second notches 42. The first notch 41 and the second notch 42 are arranged side by side in the first direction X. The first notch 41 and the second notch 42 are arranged on the first stopper 40, so that the external shape of the first stopper 40 is similar to the shape of the robot car, and the packaging box forms a robot style. Through the above arrangement, the shape of the first stopper 40 can be designed by using the position of the first stopper 40 on the outside of the packaging box 100 to form a specific packaging style, thereby improving the appearance of the packaging box 100. Alternatively, the shape design on the first stopper 40 can also match the small animal style.

[0091] In some implementable embodiments, please refer to Figures 1-2 The packaging box 100 further comprises a second stopper 50 detachably connected to the first top wall 22, and the second stopper 50 is arranged in a staggered manner between the first stopper 40.

[0092] In order to further overcome the movement trend of the first top wall 22 away from the bottom plate 10, the second stopper 50 is arranged on the first top wall 22. The second stopper 50 is detachably connected to the first top wall 22, and the second stopper 50 and the first enclosing part 20 are relatively independent structural members and do not have movement trend due to previous action. The second stopper 50 can independently generate force to overcome the movement trend of the second top wall 32 away from the bottom plate 10.

[0093] The first stopper 40 and the second stopper 50 are arranged staggeredly to avoid overlapping between the first stopper 40 and the second stopper 50 and the height overlapping of the top surface of the packaging box 100. Alternatively, to ensure the flatness of the top surface of the packaging box 100, the first stopper 40 and the second stopper 50 are arranged in the same height.

[0094] In some possible implementation manners, referring to Figures 1-2 The two second top walls 32 are arranged in the second direction Y away from the second side wall 31, and the two first stoppers 40 arranged on the two second top walls 32 are arranged in the second direction Y.

[0095] For the cuboid structure, the length dimension is usually inconsistent with the width dimension. In order to facilitate the opening of the packaging box 100, the two second side walls 31 can be arranged in the length direction with a gap, that is, the two second top walls 32 are arranged in the second direction Y with a gap, so as to facilitate the opening operation of the packaging box 100 by the technician.

[0096] Meanwhile, considering the connection stability between the first stopper 40 and the second top wall 32, the first stopper 40 is not suitable to exceed the second top wall 32, and the two first stoppers 40 are arranged in the second direction Y with a gap.

[0097] For the relative position of the second stopper 50 and the first top wall 22, the second stopper 50 can be arranged on the side of the first top wall 22 facing the bottom plate 10, or the second stopper 50 can be arranged on the side of the first top wall 22 away from the bottom plate 10. In order to form a flat structure on the side of the first top wall 22 facing the bottom plate 10, the second stopper 50 is preferably arranged on the side of the first top wall 22 away from the bottom plate 10.

[0098] Meanwhile, in order to form a flat structure on the side of the second top wall 32 facing the first top wall 22, the first stopper 40 is preferably arranged on the side of the second top wall 32 away from the bottom plate 10. Since the two second top walls 32 and the two second side walls 31 are connected by bending, the two first stoppers 40 are arranged at the two ends along the second direction Y, and the second stopper 50 is arranged in the middle along the second direction Y, and the second stopper 50 is arranged in the gap formed by the two first stoppers 40.

[0099] In some possible implementation manners, referring to Figures 1-2The second stopper 50 is arranged on the side of the first top wall 22 away from the bottom plate 10. The second stopper 50 has a fifth end D5 and a sixth end D6 in the first direction X, and the fifth end D5 and the sixth end D6 are arranged flush with the two ends of the first top wall 22 in the first direction X. The second stopper 50 has a seventh end D7 and an eighth end D8 in the second direction Y, and the seventh end D7 is arranged adjacent to the first stopper 40, and the eighth end D8 is arranged adjacent to the first stopper 40.

[0100] When the second stopper 50 is located on the side of the first top wall 22 away from the bottom plate 10, the second stopper 50 is located at the outermost side of the packaging box 100. Through the above arrangement, the second stopper 50 can be flush with the first top wall 22 in the first direction X, which can press the first top wall 22 on the whole to overcome the tendency of the first top wall 22 to move away from the bottom plate 10. On the other hand, the first stopper 40 and the second stopper 50 can cooperate to cover the top surface on the whole, which can protect the top surface to a certain extent.

[0101] Optionally, in consideration of both the ease of forming the packaging box 100 and the strength of the packaging, the bottom plate 10, the second enclosing part 30, and the first enclosing part 20 can be formed in a paper plate structure with a certain thickness, and the thickness is generally consistent. Considering that the first stopper 40 and the second stopper 50 are connected by a detachable connection mode, the material of the first stopper 40 and the second stopper 50 can be set to a material with a density greater than that of paper, so as to generate a pressing effect on the second top wall 32 and the first top wall 22 by its own weight. For example, the first stopper 40 and the second stopper 50 can be made of whiteboard, and the thickness can be 2 mm. In order to facilitate the connection of the first stopper 40 and the second stopper 50 and to make the packaging box 100 more beautiful, the first stopper 40 and the second stopper 50 can be wrapped with thin paper. The thin paper used for wrapping can be 0.15 mm.

[0102] In some implementable embodiments, please refer to Figures 1-2 The packaging box 100 includes a first box body 101 and a second box body 102. The first box body 101 includes the bottom plate 10, the first enclosing part 20, the second enclosing part 30, and the first stopper 40, and the first box body 101 is enclosed to form a containing cavity 103. The second box body 102 is located inside the containing cavity 103, and the second box body 102 includes a first wall 1021 and a second wall opposite in the thickness direction Z. The first wall 1021 is arranged with a first magnetic attraction part 1022, and the first wall 1021 is located on the side of the second wall away from the bottom plate 10. The first magnetic attraction part 1022 is arranged to overlap the projection of the first stopper 40 on the bottom plate 10.

[0103] The first box body 101 forms a containing cavity 103 as a packaging outer box, and the second box body 102 is located inside the containing cavity 103 as a packaging inner box, and the first box body 101 packages the second box body 102. The second box body 102 corresponds in shape and size to the first box body 101, and the arrangement of the second box body 102 can make the packaging of the first box body 101 more stable and fit.

[0104] The second box body 102 has opposite first and second walls in the thickness direction Z. The second wall is arranged in fit with the bottom plate 10 of the first box body 101, and the first wall 1021 is arranged in fit with the first top wall 22 of the first box body 101. The first magnetic attraction part 1022 is arranged in correspondence with the first stopper 40 in the thickness direction Z of the bottom plate 10. The first magnetic attraction part 1022 can attract the first stopper 40, so that the first stopper 40 has a tendency to face the bottom plate 10, thereby making the first stopper 40 press-fit to the second top wall 32, and then making the second top wall 32 press-fit to the first top wall 22, and improving the packaging stability of the packaging box 100.

[0105] In some implementable embodiments, please refer to Figures 2-3 The second top wall 32 is recessed inwardly at a side edge away from the second side wall 31 to form a recess 321, and the first stopper 40 includes a second magnetic attraction part 43. The first magnetic attraction part 1022 and the second magnetic attraction part 43 are arranged in overlap with the projection of the recess 321 on the bottom plate 10.

[0106] The arrangement of the recess 321 makes the second top wall 32 form a gap in the thickness direction Z. When the first magnetic attraction part 1022 and the second magnetic attraction part 43 correspond to each other in the recess 321 region, the attractive force between them does not need to pass through the block of the second top wall 32, can form a stronger force, and ensure the attractive stability between the first magnetic attraction part 1022 and the second magnetic attraction part 43, thereby ensuring the attractive stability between the first stopper 40 and the first wall 1021.

[0107] Meanwhile, the first stopper 40 can also be connected to the second top wall 32 by using the space formed by the recess 321. For example, the first stopper 40 can be connected to the second top wall 32 by using the space formed by the recess 321 through a clamping structure, and the relevant clamping structure is inside the space formed by the recess 321. The arrangement of the recess 321 can accommodate the clamping structure, thereby avoiding the clamping structure protruding from the second top wall 32, and forming a relatively flat structure at the edge of the first top wall 22.

[0108] In some implementable embodiments, please refer to Figure 4The packaging box 100 further includes a first connecting portion 60. The first side wall 21 has a third edge 211 at one end along the second direction Y, and the second side wall 31 has a fourth edge 311 at one end along the first direction X. The first connecting portion 60 is integrally connected to the third edge 211 and the fourth edge 311. The first connecting portion 60 is located within the accommodating cavity 103 formed by the bottom plate 10, the first enclosing portion 20, and the second enclosing portion 30.

[0109] In order to improve the packaging effect of the edges of the rectangular parallelepiped structure along the height direction of the packaging box 100, the packaging box 100 also includes a first connecting portion 60. The first connecting portion 60 connects the first side wall 21 and the second side wall 31 into an integral structure, so that the first side wall 21 and the second side wall 31 are seamlessly connected, and a good packaging effect can be achieved for the edges between the first side wall 21 and the second side wall 31. At the same time, in order not to affect the external shape of the packaging box 100, the first connecting portion 60 is located inside the accommodating cavity 103 formed by the bottom plate 10, the first enclosing portion 20, and the second enclosing portion 30.

[0110] The provision of the first connecting portion 60 not only allows for good packaging of the edge between the first side wall 21 and the second side wall 31, but also facilitates the opening of the packaging box 100. During the opening process of the packaging box 100, the first side wall 21 and the second side wall 31 are flipped in different directions. Without the provision of the first connecting portion 60, the first side wall 21 and the second side wall 31 are two independent structures, and flipping them in different directions requires two flips. Based on the premise that the first connecting portion 60 connects the first side wall 21 and the second side wall 31 into an integrated structure, during the flipping process of the first side wall 21, the first side wall 21 will drive the first connecting portion 60 to flip, thereby driving the second side wall 31 to flip. In the above-mentioned flipping process, only one flip is required to produce a certain degree of linkage effect with the help of the integrated structure formed by the first side wall 21, the first connecting portion 60 and the second side wall 31, thereby facilitating the opening of the packaging box 100.

[0111] In some feasible embodiments, the first connecting portion 60 can be configured as a connecting rope, one end of which is connected to the first side wall 21, and the other end is connected to the second side wall 31, and the connecting rope is located inside the accommodating cavity 103. When the packaging box 100 is opened, the connecting rope generates a linkage between the first side wall 21 and the second side wall 31.

[0112] In some possible implementations, see Figures 3-4 The first connecting portion 60 can be set as a paper structure, and the first connecting portion 60 of the paper structure is placed inside the accommodating cavity 103 by folding.

[0113] Specifically, the first connecting part 60 comprises a first sub-part 61 and a second sub-part 62 which are arranged in a bending and adhering manner, the first sub-part 61 is connected to the third edge 211, and the second sub-part 62 is connected to the fourth edge 311. Wherein, the first sub-part 61 is arranged in an adhering manner with the surface of the first side wall 21 facing the accommodating cavity 103; or, the second sub-part 62 is arranged in an adhering manner with the surface of the second side wall 31 facing the accommodating cavity 103.

[0114] The first sub-part 61 is connected to the first side wall 21, and the second sub-part 62 is connected to the second side wall 31, while the first sub-part 61 and the second sub-part 62 are arranged in a bending and adhering manner. It can be understood that the first connecting part 60 is arranged inside the accommodating cavity 103 in a folding manner, and after the first connecting part 60 is folded, the first sub-part 61 and the second sub-part 62 form two parts of the first connecting part 60 in a folding manner, and the shape and size of the first sub-part 61 and the second sub-part 62 are the same.

[0115] Optionally, after the first connecting part 60 is folded inside the accommodating cavity 103, the first connecting part 60 can be arranged on one side of the first side wall 21. That is, the first sub-part 61 connected to the third edge 211 of the first side wall 21 is bent along the third edge 211, so that the first sub-part 61 adheres to the first side wall 21, and the second sub-part 62 is reversely bent and adheres to the first sub-part 61. In the first direction X, the first side wall 21, the first sub-part 61 and the second sub-part 62 are arranged in an adhering manner from outside to inside.

[0116] Optionally, after the first connecting part 60 is folded inside the accommodating cavity 103, the first connecting part 60 can be arranged on one side of the second side wall 31. That is, the second sub-part 62 connected to the fourth edge 311 of the second side wall 31 is bent along the fourth edge 311, so that the second sub-part 62 adheres to the second side wall 31, and the first sub-part 61 is reversely bent and adheres to the second sub-part 62. In the second direction Y, the second side wall 31, the second sub-part 62 and the first sub-part 61 are arranged in an adhering manner from outside to inside.

[0117] Since the first sub-part 61 and the second sub-part 62 are arranged in an adhering manner inside the accommodating cavity 103, when the first sub-part 61 and the second sub-part 62 are arranged on one side of the first side wall 21, the stacking size of the first side wall 21 in the first direction X will be increased; when the first sub-part 61 and the second sub-part 62 are arranged on one side of the second side wall 31, the stacking size of the second side wall 31 in the second direction Y will be increased. In order to make the packaging stacking size of the packaging box 100 on each side wall as consistent and flat as possible, the first sub-part 61 and the second sub-part 62 are arranged to adhere in the same direction.

[0118] Exemplarily, the packaging box 100 has two first side walls 21 and two second side walls 31, and four first connecting portions 60 are needed to connect each first side wall 21 and each second side wall 31, that is, the first sub-portion 61 and the second sub-portion 62 of the four first connecting portions 60 are adhered in the same direction. Alternatively, the first sub-portion 61 and the second sub-portion 62 of the four first connecting portions 60 are adhered at one end in the first direction X, and the first sub-portion 61 of each first connecting portion 60 is arranged to adhere to the surface of the first side wall 21 facing the accommodating cavity 103. The packaging stack-up size of the first side wall 21 in the first direction X is the sum of the sizes of the first side wall 21, the first sub-portion 61 and the second sub-portion 62 in the first direction X, and the packaging stack-up size of the second side wall 31 in the second direction Y is the size of the second side wall 31 itself in the second direction Y. In the above manner, the packaging stack-up sizes of the two first side walls 21 on the side where they are located are consistent, and the packaging stack-up sizes of the two second side walls 31 on the side where they are located are consistent, so as to ensure that the packaging stack-up sizes of the packaging box 100 on each side wall are as consistent and flat as possible. Alternatively, the first sub-portion 61 and the second sub-portion 62 of the four first connecting portions 60 can also be adhered at one end in the second direction Y, and the process of adhesion is consistent with the above analysis, which will not be described here.

[0119] In some implementable embodiments, referring to Figures 3-4 , the packaging box 100 further comprises a second connecting portion 70, which is connected to the first top wall 22 and the second top wall 32 and located between the first top wall 22 and the second top wall 32.

[0120] The arrangement of the second connecting portion 70 can facilitate the opening of the packaging box 100. In the opening process of the packaging box 100, the first top wall 22 and the second top wall 32 are respectively flipped in different directions. If the second connecting portion 70 is not arranged, the first top wall 22 and the second top wall 32 are two independent structures, and the flipping in different directions needs to be performed twice. Based on the premise that the first connecting portion 60 connects the first side wall 21 and the second side wall 31, in the flipping process of the second side wall 31, the second side wall 31 will drive the second connecting portion 70, thereby driving the first side wall 21 to flip. In the above flipping process, only one flipping is needed, and a certain degree of linkage effect can be generated by the mutual connection structure among the second side wall 31, the second connecting portion 70 and the first side wall 21, thereby facilitating the opening of the packaging box 100.

[0121] In some implementable embodiments, the second connecting portion 70 can be arranged in the form of a connecting rope, one end of the connecting rope is connected to the first top wall 22, the other end is connected to the second top wall 32, and the connecting rope is inside the first top wall 22 and the second top wall 32. In the opening process of the packaging box 100, the connecting rope produces a linkage effect between the second top wall 32 and the first top wall 22.

[0122] In some implementable embodiments, referring to Figure 2 , Figure 4 and Figure 5 , the second connecting portion 70 can be provided as a paper structure, which is folded between the second top wall 32 and the first top wall 22. During the folding of the second connecting portion 70, part of the second top wall 32 will be moved.

[0123] Specifically, the second top wall 32 comprises a third sub-portion 322 and a fourth sub-portion 323 connected by bending, the first stopper 40 is at least partially attached to one side of the third sub-portion 322 away from the bottom plate 10, and the fourth sub-portion 323 is attached to one side of the third sub-portion 322 towards the bottom plate 10. The third sub-portion 322 comprises a fifth edge 3221 connected to the second side wall 31, and the fourth sub-portion 323 comprises a sixth edge 3231, the fifth edge 3221 and the sixth edge 3231 overlap in the orthographic projection of the bottom plate 10. The first top wall 22 has a seventh edge 221 at one end in the second direction Y, and the second connecting portion 70 is integrally connected to the sixth edge 3231 and the seventh edge 221.

[0124] The third sub-portion 322 and the fourth sub-portion 323 are connected by bending, and the fourth sub-portion 323 is attached to one side of the third sub-portion 322 towards the bottom plate 10. It can be understood that the fourth sub-portion 323 is folded along the connecting line between the third sub-portion 322 to attach the fourth sub-portion 323 to the third sub-portion 322.

[0125] Referring to Figure 5 , Figure 6 , Figure 7 and Figure 8 , the third sub-portion 322 comprises a fifth edge 3221 connected to the second side wall 31, and the fourth sub-portion 323 has a sixth edge 3231 opposite to the fifth edge 3221. After the fourth sub-portion 323 is folded along the connecting line between the third sub-portion 322, the sixth edge 3231 coincides with the fifth edge 3221, and the fourth sub-portion 323 is attached to the third sub-portion 322.

[0126] The third sub-portion 322 and the fourth sub-portion 323 are both part of the structure of the second top wall 32, and are attached to each other by bending, which can provide sufficient space for the second connecting portion 70. Specifically, the first top wall 22 has a seventh edge 221 in the second direction Y, and the fourth sub-portion 323 of the second top wall 32 has a sixth edge 3231, and the second connecting portion 70 is connected between the sixth edge 3231 and the seventh edge 221 to connect the second top wall 32 and the first top wall 22.

[0127] In the process of bending the first top wall 22 relative to the first side wall 21, the seventh edge 221 is flipped, which drives the second connecting part 70 to act, and then drives the sixth edge 3231 to flip, so that the fourth sub-part 323 is bent relative to the third sub-part 322, and when the first top wall 22 is covered on the top surface of the packaging box 100, the fourth sub-part 323 is attached to the third sub-part 322. Then the third sub-part 322 is bent relative to the second side wall 31 and covers the first top wall 22. On the top surface of the packaging box 100, the second connecting part 70, the first top wall 22, the fourth sub-part 323, and the third sub-part 322 are arranged in sequence from inside to outside.

[0128] At the same time, in order to avoid the influence of the fourth sub-part 323 on the first stopper 40, the first stopper 40 is connected to the third sub-part 322. The recess 321 on the second top wall 32 is arranged between the third sub-part 322 and the fourth sub-part 323, and after the third sub-part 322 and the fourth sub-part 323 are bent and attached to each other, the opening angle of the recess 321 on the second top wall 32 becomes smaller, and the partial opening of the recess 321 on the third sub-part 322 and the partial opening of the recess 321 on the fourth sub-part 323 are attached and overlapped with each other. Through the above arrangement, the recess around the second magnetic attraction part 43 of the first stopper 40 can avoid the second magnetic attraction part 43 to reduce the interference with the attraction force of the second magnetic attraction part 43.

[0129] In some implementable embodiments, the first connecting part 60 and the second connecting part 70 can be connected to each other to further facilitate the opening of the packaging box 100. In the process of opening the packaging box 100, first, the second top wall 32 is flipped open, and the flipping of the second top wall 32 can drive the second connecting part 70 to act with the second side wall 31. Under the action of the second connecting part 70 in the above process, the first top wall 22 and the first connecting part 60 can be actuated, the first top wall 22 can act on the first side wall 21, and the first connecting part 60 can act on the first side wall 21 and the second side wall 31. That is, the connection between the first connecting part 60 and the second connecting part 70 is equivalent to connecting the first enclosing part 20 and the second enclosing part 30, and each side wall of the packaging box 100 can be subjected to force from multiple directions, which is more convenient for opening the packaging box 100.

[0130] In some implementable embodiments, please refer to Figure 1 , Figure 2 and Figure 3 , the bottom plate 10, the first enclosing part 20, the second enclosing part 30, the first connecting part 60, and the second connecting part 70 are arranged as an integrated structure, which is directly formed by integral molding. This not only can improve the production efficiency of the packaging box 100 and reduce the production cost, but also can use the integrated structure to form the packaging box 100, which is convenient to open while taking into account the packaging effect.
