Description

Technical Field

[0001] This application relates to the technical field of logistics packaging, and in particular to a packaging box. Background Technology

[0002] With the booming development of e-commerce, the use of express delivery boxes, as the core protective carrier in the transportation process, is increasing daily, and the requirements for packaging efficiency are also constantly rising. To meet the space optimization needs of packaging boxes in warehousing and transportation, express delivery boxes generally adopt a foldable design, that is, they are folded to compress their volume when not in use and unfolded to take shape when needed. However, the folding and unfolding process of traditional foldable express delivery boxes is cumbersome, affecting the warehousing and turnover efficiency of express delivery. Utility Model Content

[0003] Therefore, it is necessary to provide a packaging box that addresses the problems of cumbersome and inefficient sealing operations in traditional packaging technologies.

[0004] The technical solution is as follows:

[0005] One embodiment provides a packaging box, comprising:

[0006] The bottom assembly includes a first bottom plate, a second bottom plate, a third bottom plate, and a fourth bottom plate;

[0007] A side assembly, comprising a first side plate, a second side plate, a third side plate, a fourth side plate, a first bent plate, and a second bent plate, wherein the first side plate, the second side plate, the third side plate, and the fourth side plate are sequentially and bendably connected end-to-end to form a loading cavity. A first bottom plate is rotatably disposed on one side of the first side plate, a second bottom plate is rotatably disposed on one side of the second side plate, a third bottom plate is rotatably disposed on one side of the third side plate, and a fourth bottom plate is rotatably disposed on one side of the fourth side plate, such that the first bottom plate, the second bottom plate, the third bottom plate, and the fourth bottom plate form the edge of one side of the loading cavity. The first bent plate is bendably disposed on the first bottom plate, with its inner surface conforming to the outer surface of the second bottom plate. The second bent plate is rotatably disposed on the third bottom plate, with its inner surface conforming to the outer surface of the fourth bottom plate.

[0008] A first connector and a second connector are provided, the first connector being disposed on the inner side of the third side plate and the second connector being disposed on the inner side of the fourth side plate, the first connector being capable of engaging or disengaging from the second connector.

[0009] The aforementioned packaging box has four side panels that can be bent sequentially, enabling the box to be folded and unfolded. When delivered to the user, the box is in a folded state. At this time, the inner surfaces of the first and second side panels are fitted together, as are the inner surfaces of the third and fourth side panels. The first bending plate and the first bottom plate are fitted together, and the second bending plate and the third bottom plate are fitted together to compress the volume. Simultaneously, the first connecting piece on the inner surface of the third side panel and the second connecting piece on the inner surface of the fourth side panel engage to prevent the first and second side panels from springing back after folding, thus improving the stability of the box after folding. When the user needs to unfold the box and place it... When in use, the first and second side panels are unfolded, as are the third and fourth side panels. The first and second connecting pieces are detached. During the unfolding of the first and second side panels, under the traction of the first bending plate, the first and second bottom plates gradually become perpendicular to the first and second side panels, respectively. During the unfolding of the third and fourth side panels, under the traction of the second bending plate, the third and fourth bottom plates gradually become perpendicular to the third and fourth side panels, respectively. This allows the first, second, third, and fourth bottom plates to be joined together to form the bottom of the loading cavity, facilitating the loading of subsequent items. Compared with traditional technologies, the folding, storage, and unfolding process of the above-mentioned packaging box is simple and fast, improving the user's operational efficiency and thus enhancing the warehousing and turnover efficiency of express delivery.

[0037] Please see Figures 1 to 6One embodiment of this application provides a packaging box, including a bottom assembly 100, a side assembly 200, a first connecting member 231, and a second connecting member 241. The bottom assembly 100 includes a first bottom plate 110, a second bottom plate 120, a third bottom plate 130, and a fourth bottom plate 140. The side assembly 200 includes a first side plate 210, a second side plate 220, a third side plate 230, a fourth side plate 240, a first bending plate 150, and a second bending plate 160. The first side plate 210, the second side plate 220, the third side plate 230, and the fourth side plate 240 are sequentially connected end-to-end in a bendable manner to form a loading cavity 410. The first bottom plate 110 is rotatably disposed on one side of the first side plate 210, and the second bottom plate 120 is rotatably disposed on one side of the second side plate 220. The base plate 130 is rotatably disposed on one side of the third side plate 230, and the fourth base plate 140 is rotatably disposed on one side of the fourth side plate 240, so that the first base plate 110, the second base plate 120, the third base plate 130 and the fourth base plate 140 form the edge of one side of the loading cavity 410. The first bent plate 150 is foldably disposed on the first base plate 110, and the inner side of the first bent plate 150 is attached to the outer side of the second base plate 120. The second bent plate 160 is rotatably disposed on the third base plate 130, and the inner side of the second bent plate 160 is attached to the outer side of the fourth base plate 140. The first connecting member 231 is disposed on the inner side of the third side plate 230, and the second connecting member 241 is disposed on the inner side of the fourth side plate 240. The first connecting member 231 can be engaged or disengaged from the second connecting member 241.

[0038] The aforementioned packaging box, with its first side panel 210, second side panel 220, third side panel 230, and fourth side panel 240, can be bent sequentially to achieve folding and unfolding. When delivered to the user, the packaging box is in a folded state. At this time, the inner surfaces of the first side panel 210 and second side panel 220 are fitted together, the inner surfaces of the third side panel 230 and fourth side panel 240 are fitted together, the first bending plate 150 and the first bottom plate 110 are fitted together, and the second bending plate 160 and the third bottom plate 130 are fitted together to compress the volume. Simultaneously, the first connecting piece 231 on the inner surface of the third side panel 230 and the second connecting piece 241 on the inner surface of the fourth side panel 240 can engage to prevent the first side panel 210 and second side panel 220 from springing back after folding, thus affecting the folding and unfolding effect of the packaging box and improving its stability after folding. When the user needs to unfold the packaging box for use, the first side panel 210... 10 and the second side panel 220 are unfolded, and the third side panel 230 and the fourth side panel 240 are unfolded. The first connecting piece 231 and the second connecting piece 241 are detached. During the unfolding of the first side panel 210 and the second side panel 220, under the traction of the first bending plate 150, the first bottom plate 110 and the second bottom plate 120 gradually become perpendicular to the first side panel 210 and the second side panel 220, respectively. During the unfolding of the third side panel 230 and the fourth side panel 240, under the traction of the second bending plate 160, the third bottom plate 130 and the fourth bottom plate 140 gradually become perpendicular to the third side panel 230 and the fourth side panel 240, respectively. Thus, the first bottom plate 110, the second bottom plate 120, the third bottom plate 130 and the fourth bottom plate 140 are spliced ​​together to form the bottom of the loading cavity 410, so as to facilitate the loading of subsequent items. Compared with traditional technology, the above-mentioned folding, storage and unfolding process of the packaging box is simple and fast, improving the user's operating efficiency, thereby improving the warehousing and turnover efficiency of express delivery.

[0039] Further, please refer to Figure 4 When the packaging box is unfolded, the first bending plate 150 and the first bottom plate 110 are on the same plane, and the second bending plate 160 and the third bottom plate 130 are on the same plane; please refer to Figure 5 and Figure 6When the packaging box is in the folded storage state, the first bottom plate 110, the second bottom plate 120, the third bottom plate 130, and the fourth bottom plate 140 all flip into the loading cavity 410. The first bottom plate 110, the second bottom plate 120, the third bottom plate 130, and the fourth bottom plate 140 overlap with the side assembly 200. The first bent plate 150 is bent relative to the first bottom plate 110 and fits against the first bottom plate 110, so that the first bottom plate 110, the first bent plate 150, and the second bottom plate 120 are stacked in sequence. The second bent plate 160 is relative to the second bottom plate 200. The base plate 120 is bent and attached to the second base plate 120 so that the third base plate 130, the second bending plate 160 and the fourth base plate 140 are stacked in sequence to reduce space occupation. During this process, the first bending plate 150 mainly plays a mutual pulling role on the first base plate 110 and the second base plate 120. When the first base plate 110 is flipped, the second base plate 120 can also be flipped under the pulling action of the first bending plate 150. The second bending plate 160 is similar to the first bending plate 150, thereby improving the folding and storage efficiency of the packaging box.

[0040] Please see Figure 1 and Figure 4 In one embodiment, the first bending plate 150 is generally triangular, the hypotenuse of the first bending plate 150 is flipped and disposed on one side of the first base plate 110, and one side of the first bending plate 150 is attached to the second base plate 120.

[0041] Optionally, one side of the first bent plate 150 can be bonded to the second base plate 120 by means of hot melting, adhesive, Velcro, etc., without specific limitations.

[0042] Preferably, one side of the first bent plate 150 is bonded to the second base plate 120 by hot-melt bonding, which has low implementation cost and reliable bonding and fixing effect.

[0043] The second bending plate 160 is similar to the first bending plate 150, and will not be described again here.

[0044] Understandably, in other embodiments, the inner side of the third side plate 230 may also be provided with a first connecting member 231, and the inner side of the fourth side plate 240 may also be provided with a second connecting member 241, as long as it can improve the stability of the packaging box in the folded storage state, which will not be elaborated here.

[0045] Optionally, the first connector 231 and the second connector 241 can be connected by Velcro, snap fasteners, or other means, as long as they can be joined or separated. No specific limitations are imposed here.

[0046] Please see Figure 1In one embodiment, the first bonding member 231 is provided with a first adhesive surface, and the second bonding member 241 is provided with a second adhesive surface, wherein the first adhesive surface can be bonded to the second adhesive surface.

[0047] By bonding the first adhesive surface and the second adhesive surface, the third side plate 230 and the fourth side plate 240 are prevented from rebounding and affecting the stacking of the packaging box. The recycling volume can also be further compressed, making it easier to recycle.

[0048] Please see Figure 5 and Figure 6 In one embodiment, when the packaging box is in a folded storage state, the first side plate 210, the first bottom plate 110, the first bending plate 150, the second bottom plate 120 and the second side plate 220 are stacked in sequence, and the fourth side plate 240, the fourth bottom plate 140, the second bending plate 160, the third bottom plate 130 and the third side plate 230 are stacked in sequence, which will not be described in detail here.

[0049] Please see Figure 1 In one embodiment, the bottom assembly 100 further includes a lifting member 570 disposed on the second bottom plate 120.

[0050] When staff need to change the packaging box from the unfolded state to the folded storage state, the second bottom plate 120 can be lifted by the lifting component 570, causing the second bottom plate 120 to flip into the loading cavity 410. Under the traction of the first bending plate 150, the first bottom plate 110 also bends into the loading cavity 410. At the same time, the first side plate 210, the second side plate 220, the third side plate 230 and the third side plate 230 are also folded and stored, thereby driving the third bottom plate 130 and the fourth bottom plate 140 to flip into the loading cavity 410, thus realizing the folding and storage of the packaging box.

[0051] Understandably, in other embodiments, the lifting member 570 may not be provided, and a folding and storage process similar to that described above can be achieved by applying a pushing force toward the loading cavity 410 to the first base plate 110.

[0052] Please see Figure 1 In one embodiment, the lifting member 570 is provided with a first connecting part and a second connecting part. The first connecting part is located on the side edge of the second base plate 120 away from the second side plate 220, and the second connecting part protrudes from the side edge of the second base plate 120 away from the second side plate 220. The second connecting part is provided with a third adhesive surface, and the fourth base plate 140 is provided with a fourth adhesive surface 580. The third adhesive surface can be bonded to the fourth adhesive surface 580.

[0053] The lifting member 570 is disposed on the edge of the second base plate 120 away from the second side plate 220 via the first connecting part. In this way, it is easier to lift the second base plate 120 by means of the lifting member 570. The second connecting part of the lifting member 570 protrudes from the edge of the second base plate 120 away from the second side plate 220 so that the third adhesive surface of the second connecting part can be bonded to the fourth adhesive surface 580 of the fourth base plate 140, thereby improving the stability of the bottom of the packaging box when it is unfolded and preventing the bottom from shaking.

[0054] In one embodiment, the fourth adhesive surface 580 is located on the edge of the fourth base plate 140 near the fourth side plate 240.

[0055] Furthermore, the fourth adhesive surface 580 is provided on the inner side of the fourth base plate 140, and the third adhesive surface is provided on the side of the second connecting part facing the fourth base plate 140.

[0056] Furthermore, the length of the second base plate 120 along the width direction of the packaging box is equal to the width of the packaging box, so that the second base plate 120 can be bonded to the fourth bonding surface 580 of the fourth base plate 140.

[0057] Optionally, the bonding method between the first adhesive surface and the second adhesive surface, as well as between the third adhesive surface and the fourth adhesive surface 580, can be pressure-sensitive adhesive or Velcro, etc., without specific limitations.

[0058] Preferably, the bonding method between the first adhesive surface and the second adhesive surface, as well as between the third adhesive surface and the fourth adhesive surface 580, adopts Velcro, which not only has low implementation cost, but also enables repeated bonding and use.

[0059] Please see Figures 1 to 3 In one embodiment, the packaging box further includes a top assembly 300, which includes a first connecting plate 310, a second connecting plate 320, a first shielding plate 330, and a second shielding plate 340. The first connecting plate 310 is rotatably disposed on the side of the first side plate 210 away from the first bottom plate 110. The first shielding plate 330 is rotatably disposed on the side of the second side plate 220 away from the second bottom plate 120. The second connecting plate 320 is rotatably disposed on the side of the third side plate 230 away from the third bottom plate 130. The second shielding plate 340 is rotatably disposed on the side of the fourth side plate 240 away from the fourth bottom plate 140. The first connecting plate 310, the first shielding plate 330, the second connecting plate 320, and the second shielding plate 340 form a loading opening 420 communicating with the loading cavity 410, so that the top assembly 300 can open or cover the loading opening 420.

[0060] When the packaging box is in the unfolded state, the first side plate 210, the second side plate 220, the third side plate 230 and the fourth side plate 240 are arranged around the bottom component 100 to form a connected loading cavity 410 and a loading port 420. In use, the staff puts the items into the loading cavity 410 through the loading port 420. When it is necessary to seal the loading port 420, the first connecting plate 310 and the second connecting plate 320 are first flipped to the loading port 420, and then the first shielding plate 330 and the second shielding plate 340 are flipped to the loading port 420, thereby achieving the shielding of the loading port 420.

[0061] Further, please refer to Figures 1 to 3 The first shielding plate 330 is disposed on one side of the side component 200 along the width direction of the packaging box, and the second shielding plate 340 is disposed on the other side of the side component 200 along the width direction of the packaging box. The length of the first shielding plate 330 is greater than or equal to the length of the loading opening 420, and the length of the second shielding plate 340 is greater than or equal to the length of the loading opening 420. In this way, when the first shielding plate 330 and the second shielding plate 340 are flipped over and the loading opening 420 is covered, the loading opening 420 can be completely covered, ensuring the sealing reliability of the packaging box.

[0062] Please see Figures 1 to 3 In one embodiment, the packaging box further includes a connecting assembly, which includes a first connector 510, a second connector 540, a first mating member 520, a second mating member 530, a third mating member 550, and a fourth mating member 560. The first connector 510 is disposed on the first connecting plate 310, the second connector 540 is disposed on the second connecting plate 320, the first mating member 520 and the third mating member 550 are spaced apart on the first shielding plate 330, and the second mating member 530 and the fourth mating member 560 are spaced apart on the second shielding plate 340. When the top assembly 300 shields the loading port 420, the first mating member 520 and the second mating member 530 are both connected to the first connector 510, and the third mating member 550 and the fourth mating member 560 are both connected to the second connector 540.

[0063] When it is necessary to cover the loading port 420, firstly, the first connecting plate 310 and the second connecting plate 320 are flipped to the loading port 420, then the first covering plate 330 and the second covering plate 340 are flipped to the loading port 420. Subsequently, the first mating part 520 is connected to the first connecting part 510, the second mating part 530 is connected to the first connecting part 510, the third mating part 550 is connected to the second connecting part 540, and the fourth mating part 560 is connected to the second connecting part 540. This is to prevent the first covering plate 330 and the second covering plate 340 from moving and affecting the reliability of the covering of the loading port 420, to prevent items from falling out of the packaging cavity during transportation, to simplify the sealing process of the packaging box, and to improve operational efficiency.

[0064] To explain, when the top assembly 300 covers the loading port 420, the first connecting plate 310 is located inside the first covering plate 330 and the second covering plate 340, and both the first mating part 520 and the second mating part 530 are connected to the first connecting part 510. At the same time, the mutual abutment between the inner side of the first covering plate 330 and the inner side of the second covering plate 340 and the outer side of the first connecting plate 310 prevents the first covering plate 330, the second covering plate 340 and the first connecting plate 310 from moving after covering the loading port 420, thereby ensuring the sealing reliability of the packaging box.

[0065] Optionally, the connection between the first mating part 520 and the first connecting part 510 can be achieved by bonding, snap-fit ​​connection, or other methods, as long as a convenient and stable connection can be achieved, and no specific limitation is made here; the second mating part 530, the third mating part 550 and the fourth mating part 560 are similar to the first mating part 520, and will not be described in detail here.

[0066] Please see Figure 1 and Figure 2 In one embodiment, the first connector 510 is disposed on the outer side of the first connecting plate 310, the first mating member 520 is disposed on the inner side of the first shielding plate 330, and the second mating member 530 is disposed on the inner side of the second shielding plate 340.

[0067] Thus, when it is necessary to seal the loading port 420, the first connecting plate 310 is first flipped to the loading port 420, and then the first shielding plate 330 and the second shielding plate 340 are flipped to the loading port 420, so that the inner side of the first shielding plate 330 and the inner side of the second shielding plate 340 face the outer side of the first connecting plate 310, thereby achieving the shielding of the loading port 420. Subsequently, the first mating member 520 located on the inner side of the first shielding plate 330 is connected to the first connecting member 510 located on the outer side of the first connecting plate 310, and the second mating member 530 located on the inner side of the second shielding plate 340 is connected to the first connecting member 510 located on the outer side of the first connecting plate 310, so as to prevent the first shielding plate 330 and the second shielding plate 340 from moving and affecting the reliability of shielding the loading port 420.

[0068] As an embodiment that can be implemented simultaneously with or separately from the above embodiments, the second connecting member 540 is disposed on the outer side of the second connecting plate 320, the third mating member 550 is disposed on the inner side of the first shielding plate 330, and the fourth mating member 560 is disposed on the inner side of the second shielding plate 340.

[0069] Similar to the above embodiments, they will not be described again here.

[0070] Understandably, the inner side mentioned above refers to the side of the corresponding plate structure facing the loading cavity 410 after the loading port 420 is covered, and the outer side refers to the side of the corresponding plate structure facing away from the loading cavity 410 after the loading port 420 is covered. Similar descriptions will follow in the following text.

[0071] Please see Figure 2 and Figure 3 In one embodiment, the first connecting plate 310, the second connecting plate 320, the first shielding plate 330, and the second shielding plate 340 are combined to form the lid structure of the packaging box. Further, the first connecting plate 310 is the left lid, the second connecting plate 320 is the right lid, the first shielding plate 330 is the upper lid, and the second shielding plate 340 is the lower lid.

[0072] Further, please refer to Figure 2 and Figure 3 The first side plate 210, the second side plate 220, the third side plate 230 and the fourth side plate 240 are connected end to end along the circumference of the bottom component 100 to form a rectangular loading cavity 410. The loading cavity 410 has a rectangular loading port 420 at one end away from the bottom component 100. The loading port 420 can be opened and covered by flipping the first connecting plate 310, the second connecting plate 320, the first shielding plate 330 and the second shielding plate 340.

[0073] Please see Figure 1 and Figure 2 In one embodiment, the first connector 510 is provided with a first adhesive surface, the first mating member 520 is provided with a first adhesive mating surface, and the second mating member 530 is provided with a second adhesive mating surface. When the top component 300 covers the loading port 420, both the first adhesive mating surface and the second adhesive mating surface are bonded to the first adhesive surface.

[0074] The connection between the first shielding plate 330 and the second shielding plate 340 and the first connecting plate 310 is achieved by adhesive bonding, which is easy to operate and has high connection efficiency.

[0075] Furthermore, the bonding method between the first adhesive mating surface and the second adhesive mating surface and the first adhesive surface can be pressure-sensitive adhesive or Velcro, etc., without specific limitations here.

[0076] Preferably, the first adhesive mating surface and the second adhesive mating surface are bonded to the first adhesive surface using Velcro, which not only has low implementation cost but also enables repeated bonding and use.

[0077] As an embodiment that can be implemented simultaneously with or separately from the above embodiments, the second connector 540 is provided with a second adhesive surface, the third mating component 550 is provided with a third adhesive mating surface, and the fourth mating component 560 is provided with a fourth adhesive mating surface. When the top component 300 covers the loading port 420, both the third adhesive mating surface and the fourth adhesive mating surface are bonded to the second adhesive surface.

[0078] The second adhesive surface is similar to the first adhesive surface, and will not be described again here.

[0079] Please see Figure 2 and Figure 3 In one embodiment, the first connecting plate 310, the second connecting plate 320, the first shielding plate 330, and the second shielding plate 340 are combined to form the lid structure of the packaging box. Further, the first connecting plate 310 is the left lid, the second connecting plate 320 is the right lid, the first shielding plate 330 is the upper lid, and the second shielding plate 340 is the lower lid.

[0080] Please see Figure 1 and Figure 2 In one embodiment, the first mating member 520 and the third mating member 550 are spaced apart along a first direction of the packaging box.

[0081] The first mating component 520 and the third mating component 550 are spaced apart on the first shielding plate 330 along the first direction, so that the first shielding plate 330 can be connected with the first connecting plate 310 and the second connecting plate 320, thereby improving the shielding reliability of the top assembly 300 on the loading port 420.

[0082] For explanation purposes, the first direction refers to the length direction of the packaging box, that is... Figure 2 The direction A in the diagram will not be elaborated upon here.

[0083] Further, please refer to Figure 2 The first connecting plate 310 is disposed on one side of the side assembly 200 along the first direction, and the second connecting plate 320 is disposed on the other side of the side assembly 200 along the first direction. The first mating member 520 and the third mating member 550 are spaced apart on the first shielding plate 330 along the first direction so that the first shielding plate 330 can be connected with the first connecting plate 310 and the second connecting plate 320.

[0084] As an embodiment that can be implemented simultaneously with or separately from the above embodiments, the second mating member 530 and the fourth mating member 560 are spaced apart along the first direction of the packaging box.

[0085] The second mating part 530 and the fourth mating part 560 are similar to the first mating part 520 and the third mating part 550, and will not be described in detail here.

[0086] Please see Figure 3In one embodiment, the first shielding plate 330 has a first connecting hole 331, the second shielding plate 340 has a second connecting hole 341, and the packaging box also includes a third connector, which passes through the first connecting hole 331 and the second connecting hole 341.

[0087] The third connector passes through the first connecting hole 331 on the first shielding plate 330 and the second connecting hole 341 on the second shielding plate 340 to further prevent the loading port 420 from opening during transportation due to movement of the first shielding plate 330 and the second shielding plate 340. This method is low in cost and simple to operate.

[0088] Furthermore, the third connecting component is a cable tie. After the loading port 420 is covered by the first shielding plate 330 and the second shielding plate 340, the cable tie is passed through the first connecting hole 331 and the second connecting hole 341 and tied tightly to achieve the positioning of the first shielding plate 330 and the second shielding plate 340.

[0089] Please see Figure 1 In one embodiment, the side assembly 200 is provided with a handle 600 to facilitate the handling of the packaging box by staff.

[0090] Furthermore, the handle 600 can be provided on the first side plate 210 and the third side plate 230, or on the second side plate 220 and the fourth side plate 240, without specific limitations.

[0091] Please see Figure 1 In one embodiment, the side assembly 200 further includes a fixing part 250, which is disposed on the edge of the fourth side plate 240 away from the third side plate 230. The side of the fourth side plate 240 away from the third side plate 230 is connected to the side of the first side plate 210 away from the second side plate 220 through the fixing part 250, so that the first side plate 210, the second side plate 220, the third side plate 230 and the fourth side plate 240 are connected end to end in sequence along the circumference of the bottom assembly 100.

[0092] Furthermore, the fixing part 250 and the first side plate 210 can be heat-fused together using ultrasonic or other methods.

[0093] In one embodiment, at least one of the top component 300, the side component 200, and the bottom component 100 has a frosted surface, which makes the labels on the packaging box easier to peel off, reduces adhesive residue, and makes cleaning easier.

[0094] In one embodiment, the edges of the packaging box are sealed with rounded corners, eliminating burrs and preventing cuts.

[0095] In one embodiment, at least one of the top component 300, the side component 200, and the bottom component 100 is made of hollow board, thereby reducing the overall weight of the packaging box.

[0096] Using the packaging box in this application makes packing items more convenient. Switching from folded storage to unfolded state and from unfolded state to folded storage state takes only about 7 seconds. In addition, the packaging box in this application can be reused as a recycling box, and the folding and unfolding process is quick.

[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
