[0040] The present application provides a packaging box, which not only meets the buffering requirements, is not only more environmentally friendly, but also allows users to take out products from the packaging box more conveniently.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] See also Figure 1 to Figure 3 , the embodiment of the present application provides a packaging box, which is folded from a cardboard, including a box body for providing a receiving space and a buffer part located in the receiving space, that is, when the cardboard is folded to form the packaging box, the first part of the cardboard is folded into a box body that can provide a receiving space, and the second part of the cardboard is folded into a buffer part for buffering the target device 100 to be contained, and the buffer part can protect the target device 100 during transportation. The packaging box has a packaging state and a disassembly state. In the packaging state, the buffer part forms a receiving position in the receiving space to fix the target device 100 to the receiving position. In the process of the packaging box changing from the packaging state to the disassembly state, the buffer part can be deformed to destroy the receiving position, so as to facilitate the removal or placement of the target device 100. It is easy to understand that the packaging state is the state after the packaging box is packed, and the disassembly state is the state after the packaging box is opened. Since the packaging box of the present application is folded from a cardboard and folded to form a buffer part, there is no need to insert additional buffers of other materials, so that the packaging box meets the buffering requirements and is more environmentally friendly. Moreover, when the user packs or opens the packaging box, the buffer portion can be deformed, and the deformation destroys the accommodating position formed by the buffer portion in the packaged state that fits tightly with the target device 100, making the buffer portion and the target device 100 looser, thereby making it more convenient to take and put the target device 100.

[0043] like Figure 2 and Figure 3As shown, in a preferred embodiment, the cardboard is folded to form a first body A, a second body B and a third body C, and the second body B and the third body C are respectively connected to the first body A in rotation to form a box body. A first buffer portion is provided in the accommodation space of the box body. In the packaging state, the second body B and the third body C are respectively covered on the first body A, and the first buffer portion cooperates with at least the second buffer portion provided on the second body B to form an accommodation position to fix the target device 100 in the accommodation position; in the disassembly state, the second body B and the third body C are respectively opened and closed with the first body A to corresponding angles to destroy the accommodation position, so as to facilitate the removal or placement of the target device 100. Specifically, the first body A includes the bottom surface and three side surfaces of the box body, the second body B includes another side surface of the box body, and the third body C includes the top surface of the box body. The third body C is connected to any one of the three side surfaces of the first body A. Preferably, the third body C is connected to the side surface opposite to the second body B. The second body B is preferably arranged to be connected to the bottom surface of the first body A, that is, when the packaging box is opened, the second body B and the third body C rotate relative to the first body A in opposite directions. Depend on Figure 3 It can be seen that in this embodiment, when the user takes the target device 100 (such as a laptop computer) from the sealed packaging box, the user first rotates to open the third body C. After the third body C is opened, the state of the packaging box is as follows: Figure 3 As shown in the leftmost figure, the receiving position formed by the buffer portion has not been destroyed, so the target device 100 cannot be easily taken out. Then, the second body B is rotated to open a certain angle, so that the receiving position that originally fits tightly with the target device 100 can be destroyed. After opening the second body B, the state of the packaging box is as follows: Figure 3 As shown in the middle figure, at this time, there is a gap between the target device 100 and the first buffer portion in the box body accommodating space and the second buffer portion on the second body B, so that the user can easily take the target device 100. As the opening angle of the second body B increases, the above gap becomes larger, as shown in FIG. Figure 3 As shown in the rightmost figure, at this time, the target device 100 will also slide toward the second buffer portion on the second body B.

[0044] In a further preferred embodiment, a third buffer portion is provided on the third side surface of the third body C, and the third side surface is the side surface of the third body C facing the accommodation space of the box body in the packaged state. In this structure, the first buffer portion cooperates with the third buffer portion on the third body C in addition to the second buffer portion on the second body B, so that the formed accommodation position can protect the target device 100 more comprehensively.

[0045] See also Figure 1 and Figure 2In a preferred embodiment, the first body A includes a bottom plate 1, and the second body B includes a first side plate 2 connected to a first edge of the bottom plate 1, and the first side plate 2 is connected to a first tongue 60 at both ends in a direction parallel to the first edge, and the first tongue 60 serves to fix the second body B in the packaged state. Further preferably, the cardboard includes a first buffer plate 3, a first plate body 4, a support plate 6, a second plate body 7, and a second buffer plate 8, which are sequentially connected from the first side plate 2 to the direction away from the first edge of the bottom plate 1. In the packaged state, the first plate body 4 and the second plate body 7 are opposite to each other and both meet the vertical condition with the bottom plate 1, and the first buffer plate 3, the support plate 6, and the second buffer plate 8 all meet the parallel condition with the bottom plate 1. It should be noted that for ease of understanding, Figure 1 The positive polyline in is represented by a hollow line segment, for example Figure 1 The positive broken line a in . Figure 1 The inverse line in is represented by a solid line segment, for example Figure 1 The boundary line between the support plate 6 and the second plate body 7. Figure 1 When the paperboard shown in the figure is folded to form a packaging box, the folding direction at the positive fold line is opposite to the folding direction at the negative fold line. For example, in this embodiment, the positive fold line is folded in the opposite direction. Figure 1 The drawing is folded "outward" in the normal direction of the drawing, that is, folded towards the viewer of the drawing. Figure 1 The drawing is folded "inwards" in the normal direction of the drawing surface, that is, folded towards the side facing away from the viewer of the drawing. Figure 1 and Figure 2 As shown, the aforementioned first buffer portion includes a second buffer plate 8 and a second plate body 7, and the aforementioned second buffer portion includes a first buffer plate 3 and a first plate body 4. The support plate 6 forms the bottom of the aforementioned accommodation position in the packaged state, and supports the target device 100 placed in the packaging box. Figure 2 It can be seen that when the second body B is opened, the first plate 4, the support plate 6 and the second plate 7 tend to be flattened, destroying the original accommodation position. It is easy to understand that when the second body B is closed, the first plate 4, the support plate 6 and the second plate 7 are folded back to the position in the packaging state, that is, the accommodation position can be restored after the second body B is closed.

[0046] like Figure 1 As shown, in a preferred embodiment, a first hollow area 5 is provided at the junction of the first plate body 4 and the support plate 6, that is, the first hollow area 5 is cut out at the inflection line between the first plate body 4 and the support plate 6, and the first hollow area 5 is cut out at the inflection line between the first plate body 4 and the support plate 6. Figure 2 and Figure 3 It can be seen that the first hollow area 5 can provide a hand-reaching space for the user after the second body B is opened, so that the user can take out the target device 100 more conveniently.

[0047] In a preferred embodiment, a first folding plate is connected to each of the two ends of the first plate body 4 in a direction that satisfies the parallel condition with the aforementioned first side of the bottom plate 1.

In the packaged state, the first support block is sandwiched between the first plate body 4 and the first side plate 2. The first support block can enhance the buffering effect of the second buffer part, so that the second buffer part can withstand a greater shaking force from the target device 100. Specifically, the first folding plate can include a twelfth wall 38, a thirteenth wall 39, a fourteenth wall 40, a fifteenth wall 41, a sixteenth wall 42, a seventeenth wall 43, an eighteenth wall 44, and a nineteenth wall 45 that are sequentially connected from the edge of the first plate body 4.

Specifically, the second folding plate can include a twentieth wall 46, a twenty-first wall 47, a twenty-second wall 48, and a twenty-third wall 49 that are sequentially connected from the side of the support plate 6.

[0049] In a preferred embodiment, the second buffer plate 8 is connected to a lining plate 9 at the edge away from the second plate body 7, and in the packaged state, the lining plate 9 and the second plate body 7 meet the parallel condition. In this structure, the aforementioned first buffer portion includes the second buffer plate 8, the second plate body 7 and the lining plate 9, and the lining plate 9 can form a larger contact surface between the first buffer portion and the side wall of the box body, thereby improving the overall stability of the buffer portion in the packaged state.
