DETAILED DESCRIPTION

[0035] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following exemplary embodiments described in this specification are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0036] It should be noted that, in this document, the terms "comprises", "comprising", or any other variation 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. Without further limitation, an element preceded by "comprises... a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the element. Also, the same part, feature, element, etc. in different embodiments can have the same or different meanings, which should be determined based on the specific explanation in the specific embodiment or further combined with the context in the specific embodiment.

[0037] It should be understood that, although the terms first, second, third, etc. can be employed in this disclosure to describe various information, these information should not be limited to these terms. These terms are only used to differentiate one piece of information from another. For example, without departing from the scope of this disclosure, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information. Depending on the context, the word "if' as used herein can be interpreted to mean "when" or "in response to determining". Furthermore, as used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It will be further understood that the terms "comprises", "comprising", "includes" and / or "including" means that there are no other features, steps, operations, elements, components, items, kinds and / or groups that are present in the described feature, step, operation, element, component, item, kind and / or group, but it does not, by itself, preclude one or more other features, steps, operations, elements, components, items, kinds and / or groups being present in the described feature, step, operation, element, component, item, kind and / or group. The terms "or" and "and / or" as used herein are to be interpreted as inclusive or, meaning any one or any combination. Therefore, "A, B or C" or "A, B and / or C" means "any of the following: A; B; C; A and B; A and C; B and C; A, B and C". An exception to this definition will occur only when a combination of elements, functions, steps or operations are in some way inherently mutually exclusive. When describing the structure of a component, when a layer, one region is referred to as being "on" or "above" another layer, another region, it can mean directly on the other layer, another region, or there are other layers or regions between it and the other layer, another region. And if the component is turned over, the layer, one region will be "below" or "under" the other layer, another region. In the embodiments of the present application, "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that the determination of B according to A does not mean that B is determined only according to A, but B can also be determined according to A and / or other information.

[0038] It should be understood that the specific embodiments described herein merely exemplify the present application and should not be used to limit the present application.

[0039] In the following description, the suffixes "module", "part" or "unit" used for components are merely intended for facilitating explanation of the present application, and are by no means specific thereto. Therefore, "module", "part" or "unit" can be mixedly used.

[0040] In the related art, multiple sub-packaging boxes in a set packaging box are usually connected by glue, but the glue connection needs to increase an additional gluing process, resulting in additional process and material costs, and excessive use of glue will also affect the environmental protection index of the packaging box.

[0041] Therefore, in order to better understand the present application, the packaging box of the embodiments of the present application is described in detail below in combination with the drawings. In the drawings, the sizes in the drawings are not necessarily proportional to the actual sizes for the convenience of drawing. For the clarity of the drawing, part of the structure in the drawing can be hidden or partially displayed.

[0042] Please refer to Figures 1 to 3 , Figure 1 the structural schematic diagram of the packaging box provided by the embodiments of the present application; Figure 2 the perspective structural schematic diagram of the packaging box provided by the embodiments of the present application; Figure 3 the perspective structural schematic diagram of the packaging box provided by the embodiments of the present application. Among them, Figure 3 the view angle of the packaging box is different from Figure 1 , Figure 2 the view angle of the packaging box. The solid line of the reference mark represents that the reference mark refers to the entity structure that can be directly visually seen in the view angle of the drawing, and the dotted line of the reference mark represents that the reference mark refers to the structure that can be seen through the perspective in the view angle of the drawing. In order to better reflect the structure of the packaging box, Figure 2 , Figure 3 there can be part of the card board not displayed.

[0043] As shown in Figures 1 to 3 , the embodiments of the present application provide a packaging box 10, which comprises a first side plate 100, a second side plate 200, a third side plate 300, a fourth side plate 400, a bottom plate 500, a top plate 600, a first card plate 101 and a plug 102, the first card plate 101, the first side plate 100, the second side plate 200, the third side plate 300, the fourth side plate 400 and the plurality of plugs 102 are sequentially and foldably connected. The bottom plate 500 and the top plate 600 are respectively and foldably connected with the second side plate 200 and the third side plate 300, and the bottom plate 500, the top plate 600, the first side plate 100, the second side plate 200, the third side plate 300 and the fourth side plate 400 form a cavity. The first card plate 101 extends into the cavity and is located on the side of the fourth side plate 400 facing the cavity, a plurality of first sockets 201 are formed between the first card plate 101 and the first side plate 100, and at least one second socket 202 is formed between the second side plate 200 and the third side plate 300. At least one plug 102 is inserted into the first socket 201, and adjacent two packaging boxes can be connected by inserting the plug 102 of one packaging box into the second socket 202 of the other packaging box.

[0044] The bending connection refers to the connection of two plate structures, and a connection line is formed at the connection position. The two plate structures can rotate relative to the connection line, so that the angle between the two plate structures can be changed. The angle between the two plate structures formed by the bending connection is not limited, and can be an acute angle, a right angle or an obtuse angle. When the two plate structures are flattened, the angle between them can be considered as 180°. The bending connection appearing hereinafter can be referred to the above description.

[0045] Optionally, the cavity is used to accommodate the packaged material.

[0046] Optionally, the size of the plug 102 matches the size of the first plug hole 201 and the second plug hole 202, so that the plug 102 can be inserted into the first plug hole 201 and the second plug hole 202. When the packaging box is formed, at least one plug 102 is inserted into the first plug hole 201, so that the angle and the relative position relationship between the side plates, the top plate 600 and the bottom plate 500 are fixed. If necessary, the number of plugs 102 inserted into the first plug hole 201 can be increased, for example, there are three first plug holes 201 on the packaging box, and three plugs 102 are inserted into the three first plug holes 201, respectively, to improve the stability of the packaging box. When two packaging boxes need to be connected, at least one plug 102 of one packaging box is inserted into the second plug hole 202 of the other packaging box. At this time, at least one plug 102 of each packaging box is inserted into the first plug hole 201 of the packaging box to maintain the stability of the packaging box. The connection of multiple packaging boxes can be inferred by analogy with the above connection mode, and will not be described here. It is easy to think that in order to improve the connection strength between the two packaging boxes, the number of plugs 102 and second plug holes 202 inserted between the two packaging boxes can be increased.

[0047] Optionally, the number of first plug holes 201 is the same as the number of plugs 102, for example, the number of first plug holes 201 and plugs 102 is three. The number of second plug holes 202 is also the same as the number of first plug holes 201.

[0048] Optionally, after the multiple packaging boxes 10 are assembled into one, the multiple packaging boxes 10 can be packaged by a heat shrinkable film, thereby improving the connection strength of the packaging boxes 10.

[0049] The packaging box 10 provided by the embodiment of the application is provided with the first plug hole 201, the second plug hole 202 and the multiple plugs 102. When some of the plugs 102 are inserted into the first plug hole 201 to form the packaging box 10, the other plugs 102 can be inserted into the second plug hole 202 of the adjacent packaging box 10 to assemble the multiple packaging boxes 10 into one. Since the multiple packaging boxes 10 are connected by the plugs, the cost is lower and more environmentally friendly than the glue connection. Moreover, the multiple packaging boxes 10 can be repeatedly assembled and separated, thereby improving the functionality of the packaging box 10.

[0050] Please refer to Figures 1 to 6 , Figure 4 Figure 3 is a perspective view of a packaging box according to an embodiment of the present application; Figure 5 Figure 4 is a perspective view of a packaging box according to an embodiment of the present application; Figure 6 Figure 5 is a perspective view of two packaging boxes according to an embodiment of the present application. In the figure, Figure 4 Figure 5(a) shows the state of the packaging box when it is a single independent packaging box, Figure 5 Figure 5(b) shows the state of one of the packaging boxes when the two packaging boxes are assembled. In order to better reflect the structure of the packaging box, Figure 2 , Figure 3 Part of the card in Figure 5(b) is not shown.

[0051] In some optional embodiments, the first side plate 100 and the third side plate 300 are arranged opposite to each other along a first direction (X direction in the figure), the second side plate 200 and the fourth side plate 400 are arranged opposite to each other along a second direction (Y direction in the figure), and the bottom plate 500 and the top plate 600 are arranged opposite to each other along a third direction (Z direction in the figure). The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0052] In some optional embodiments, a first edge 110 extending along the third direction Z is formed between the first card 101 and the first side plate 100, and the first insertion port 201 is located on the first edge 110. A plurality of first insertion ports 201 are arranged at intervals along the third direction Z. A second edge 203 extending along the third direction Z is formed between the second side plate 200 and the third side plate 300, and the second insertion port 202 is located on the second edge 203. A plurality of second insertion ports 202 are arranged at intervals along the third direction Z. The first edge 110 is a bending line between the first card 101 and the first side plate 100, and the first card 101 and the first side plate 100 can be bent relative to the first edge 110 to change the angle formed between the first card 101 and the first side plate 100. The first insertion port 201 can be understood as a notch opened on the first edge 110 along the third direction Z. When the packaging box is formed, the first insertion port 201 communicates the inside and outside of the cavity, so that the insertion tongue 102 can extend into the cavity from the outside of the cavity through the first insertion port 201, and cooperate with the first insertion port 201 to maintain the stability of the packaging box. The structure and function of the second insertion port 202 can be referred to the first insertion port 201, which will not be described here.

[0053] In some optional embodiments, the packaging box 10 further comprises a first support plate 700 and a second support plate 800 respectively bent and connected with the bottom plate 500 and the top plate 600. The first support plate 700 and the second support plate 800 are arranged opposite to each other, and the first support plate 700 and the second support plate 800 are inclined relative to the first direction X, the second direction Y and the third direction Z.

[0054] Optionally, the first support plate 700 and the second support plate 800 are both triangular in orthographic projection shape, and the first side plate 100, the second side plate 200, the third side plate 300, the fourth side plate 400, the bottom plate 500, and the top plate 600 are all pentagonal in orthographic projection shape.

[0055] Optionally, the cavity is formed by the first side plate 100, the second side plate 200, the third side plate 300, the fourth side plate 400, the bottom plate 500, the top plate 600, the first support plate 700, and the second support plate 800. Figure 1 and Figure 2 As shown in FIGS. 1 and 2, the outer contour shape of the packaging box 10 is an octahedron, and C in the figure can be understood as a corner C of a virtual cube, and the virtual cube is also provided with a corner D opposite to the corner C, and the corner C and the corner D are located at two ends of a diagonal line passing through the center point of the packaging box 10. The corner C and the corner D of the virtual cube are cut off to form the packaging box 10, and the corner C and the corner D are cut off to form a triangular cross section, that is, the first support plate 700 and the second support plate 800. The first side plate 100, the second side plate 200, the third side plate 300, the fourth side plate 400, the bottom plate 500, and the top plate 600 are all pentagonal in orthographic projection shape after the corner A and the corner B are cut off, which are similar to a rectangle with a corner cut off.

[0056] The packaging box 10 provided by the embodiment of the present application adopts an octahedron as the outer contour to package irregular cylindrical materials, and the two ends of the material abut against the first support plate 700 and the second support plate 800 respectively to prevent the material from shaking in the packaging box 10. In addition, the packaging box 10 is similar to being obliquely cut by the first support plate 700 and the second support plate 800, which reduces the volume of the packaging box 10, improves the number of packaging boxes 10 that can be accommodated in a unit volume, and further improves the packaging efficiency of the packaging box 10 and reduces the transportation cost.

[0057] In some optional embodiments, the packaging box 10 further comprises a second clamping plate 103 connected to the first side plate 100 along the third direction Z, and the second clamping plate 103 is located on the side of the bottom plate 500 facing the cavity and abuts against the bottom plate 500.

[0058] Optionally, the first side plate 100, the second side plate 200, the third side plate 300, the fourth side plate 400, the bottom plate 500, the top plate 600, the first support plate 700 and the second support plate 800 are exposed surfaces of the packaging box 10, and the cavity is formed by the first side plate 100, the second side plate 200, the third side plate 300, the fourth side plate 400, the bottom plate 500, the top plate 600, the first support plate 700 and the second support plate 800. The first clamping plate 101 is connected to the first side plate 100 along the second direction Y and is located on the side of the first side plate 100 facing the fourth side plate 400. The first clamping plate 101 is bent by 90° relative to the first side plate 100 towards the cavity and extends into the cavity and abuts against the fourth side plate 400. The first clamping plate 101 is used to maintain the shape of the packaging box 10 and improve the stability of the fourth side plate 400. The second clamping plate 103 is located on the side of the first side plate 100 facing the bottom plate 500. The second clamping plate 103 is bent by 90° relative to the first side plate 100 towards the cavity and extends into the cavity and abuts against the bottom plate 500. The second clamping plate 103 is used to maintain the shape of the packaging box 10 and improve the stability of the bottom plate 500. In the subsequent description, the clamping plate can be understood as being connected to one of the exposed surfaces of the packaging box 10 by bending and extending into the cavity and abutting against another exposed surface, which is used to maintain the shape of the packaging box 10 and improve the stability of the exposed surface. Optionally, the packaging box 10 further comprises a third clamping plate 104 connected to the second side plate 200 by bending and located on the side of the second side plate 200 away from the bottom plate 500. The third clamping plate 104 is bent by 90° relative to the second side plate 200 towards the cavity and abuts against the top plate 600.

The fourth clamping plate 105 is used to maintain the shape of the packaging box 10 and improve the stability of the fourth side plate 400. The fourth clamping plate 105 and the first clamping plate 101 are both located on the side of the fourth side plate 400 facing the cavity and abut against the fourth side plate 400. Since the side of the fourth side plate 400 facing the cavity is supported by the first clamping plate 101 and the fourth clamping plate 105, the stability of the fourth side plate 400 is further improved.

[0060] Optionally, the packaging box 10 further comprises a fifth clamping plate 106 connected to the first support plate 700 by bending. The fifth clamping plate 106 is bent by 90° relative to the first support plate 700 towards the cavity and abuts against the third side plate 300.
