Description

Technical Field

[0001] This invention relates to the field of packaging structure technology, and in particular to a packaging paperboard and a packaging structure using the packaging paperboard. Background Technology

[0002] As people's living standards continue to improve, the demand for various products is increasing. Simultaneously, with the rapid development of the e-commerce industry, the requirements for product packaging and transportation are also rising. Therefore, the usage of packaging materials such as boxes, trays, and lids is also increasing. Currently, most products, especially those with connecting cables, are packaged by folding foldable cardboard to create separate recesses for the product and cables. This results in a large overall packaging structure, and the cables require additional binding wires for securing them, leading to uneven and messy cable management. This not only makes the product packaging process cumbersome but also time-consuming and labor-intensive. Summary of the Invention

[0003] The main objective of this invention is to provide a packaging paperboard and packaging structure, which aims to provide a packaging paperboard that can better showcase the smoothness of the winding. The packaging structure formed after the paperboard is folded adopts a snap-locking structure that is not easy to loosen. It is formed from a single sheet, with a complete structure, and combines functionality and aesthetics.

[0004] To achieve the above objectives, the present invention provides a packaging paperboard, the packaging paperboard comprising:

[0005] The base plate is provided with a snap-fit ​​part, and the base plate has adjacent first side and second side;

[0006] A cover plate, connected to the first side, folded relative to the base plate to form an accommodating space, and further having an installation opening communicating with the accommodating space; and

[0007] A limiting plate is connected to the second side. The limiting plate is provided with a snap-fit ​​part. The limiting plate is folded relative to the bottom plate so that the snap-fit ​​part is connected to the buckle part to cover the cover plate.

[0008] In one embodiment, the limiting plate is provided with a clearance opening, and after the limiting plate is folded relative to the base plate, the clearance opening is directly opposite and connected to the mounting opening;

[0009] Alternatively, the limiting plate may have a visible area, and when the limiting plate is folded relative to the base plate, the visible area is directly opposite the mounting opening.

[0010] In one embodiment, the cover plate includes:

[0011] A cover plate, one side of which is connected to the first side edge, the cover plate having the mounting opening, and a first crease formed near the first side edge; and

[0012] The first side panel includes a first segment and an adhesive segment connected together. A crease is formed at the connection between the first segment and the adhesive segment. The side of the first segment away from the adhesive segment is connected to the main cover plate and has a crease.

[0013] When the cover plate is folded relative to the base plate, the adhesive section is connected to the side of the base plate away from the first side, so that the base plate, the first section, and the cover plate form the accommodating space.

[0014] In one embodiment, the cover plate further includes:

[0015] The second side panel includes a second segment and a first abutting segment connected together. A crease is formed at the connection between the second segment and the first abutting segment. The side of the second segment away from the first abutting segment connects to one side of the main cover panel, and also forms a crease thereon.

[0016] The third side plate, the second side plate and the third side plate are located on opposite sides of the main cover plate and between the first side and the first side plate. The third side plate includes a third segment and a second abutting segment connected together. A crease is formed at the connection between the third segment and the second abutting segment. The side of the third segment away from the second abutting segment is connected to one side of the main cover plate and a crease is formed there.

[0017] When the main cover is folded relative to the base plate, the first abutting section and the second abutting section abut against the opposite sides of the base plate, so that the second section is located between the second side and the main cover, and the second section and the third section are opposite to each other, and together with the base plate, the first section and the main cover, they enclose the accommodating space.

[0018] In one embodiment, a snap hole is formed at the connection between the main cover plate and the third side plate, and the bottom plate is also provided with a snap-fit ​​plate opposite to the second side. A crease is formed at the connection between the snap-fit ​​plate and the bottom plate, and the snap-fit ​​plate is provided with a snap-fit ​​ear.

[0019] The main cover plate is folded relative to the base plate, and the snap-fit ​​plate is folded relative to the base plate so that the snap-fit ​​ear is snapped into the snap-fit ​​hole.

[0020] In one embodiment, the cover plate is further provided with a communication port, which connects the mounting port and the card hole.

[0021] In one embodiment, the adhesive segment is coated with an adhesive layer, and the adhesive segment is connected to the base plate through the adhesive layer;

[0022] And / or, the width of the second segment is the same as the width of the third segment;

[0023] And / or, the width of the first segment is the same as the distance from the first side to the first crease;

[0024] And / or, the width of the second segment and the width of the third segment are the same as the width of the first segment;

[0025] And / or, the width of the second segment and the width of the third segment are the same as the width of the snap-fit ​​plate.

[0026] And / or, the main cover is provided with two first side ears near the first side, the two first side ears are arranged opposite each other and located between the first side and the first crease, when the main cover is folded relative to the bottom plate, the two first side ears abut against the second segment and the third segment respectively;

[0027] And / or, the first side plate further includes two second side ears, which are connected to opposite sides of the first segment and located between the cover main plate and the adhesive segment. When the cover main plate is folded relative to the bottom plate, the two second side ears abut against the second segment and the third segment respectively.

[0028] In one embodiment, the limiting plate includes a pressure plate portion and a support portion connected together. A crease is formed at the connection between the pressure plate portion and the support portion. The side of the pressure plate portion away from the support portion is connected to the second side and has a crease. The support portion is provided with the snap-fit ​​portion.

[0029] When the limiting plate is folded relative to the base plate, the pressure plate covers the side of the cover plate facing away from the base plate, and the support covers the side of the base plate facing away from the cover plate, so that the snap-fit ​​part is connected to the buckle part.

[0030] In one embodiment, a second crease is formed on the side of the pressure plate portion adjacent to the second side edge;

[0031] And / or, a third crease is formed on the side of the pressure plate portion adjacent to the support portion;

[0032] And / or, after the limiting plate is folded relative to the base plate, the projected area of ​​the pressure plate portion is smaller than the projected area of ​​the support portion;

[0033] And / or, the cover plate is folded relative to the base plate, and the projected area of ​​the cover plate is equal to the projected area of ​​the base plate;

[0034] And / or, the cover plate is folded relative to the base plate, and after the limiting plate is folded relative to the base plate, the projected area of ​​the pressure plate portion is equal to the projected area of ​​the cover plate.

[0035] The present invention also proposes a packaging structure formed by folding the packaging cardboard described above.

[0036] The packaging cardboard of this invention features a snap-fit ​​part on the base plate, connecting the cover plate and the limiting plate to adjacent first and second sides of the base plate. This creates creases at the connection between the cover plate and the first side, and also at the connection between the limiting plate and the second side. The limiting plate has a snap-fit ​​part. When the cover plate is folded relative to the base plate, the cover plate and base plate enclose a storage space. The cover plate also has an installation opening connecting to this storage space, allowing products to be easily placed within it for convenient storage. Simultaneously, the product's cables can extend out of the storage space through the installation opening and smoothly wrap around it. Around the perimeter of the outer wall of the accommodating space, and after the limiting plate is folded relative to the base plate, the snap-fit ​​part is used to connect and fix the limiting plate and the base plate. At the same time, the limiting plate is used to cover the cover plate, thereby keeping the cable flat and confined around the perimeter of the outer wall of the accommodating space. The packaging structure formed by folding the packaging cardboard is not easy to loosen with the snap-fit ​​structure. It is formed in one piece of paper, with a complete structure, combining functionality and aesthetics. At the same time, it only forms an accommodating space for placing products, thereby effectively reducing the volume of the packaging structure. Moreover, the cable is wrapped around the perimeter of the outer wall of the accommodating space, which can better show the effect of the flat winding. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0052] As people's living standards continue to improve, the demand for various products is increasing. Simultaneously, with the rapid development of the e-commerce industry, the requirements for product packaging and transportation are also rising. Therefore, the usage of packaging materials such as boxes, trays, and lids is also increasing. Currently, most products, especially those with connecting cables, are packaged by folding foldable cardboard to create separate recesses for the product and cables. This results in a large overall packaging structure, and the cables require additional binding wires for securing them, leading to uneven and messy cable management. This not only makes the product packaging process cumbersome but also time-consuming and labor-intensive.

[0053] Based on the above concepts and problems, this invention proposes a packaging paperboard 100. It is understood that the packaging paperboard 100 is also used to fold and form a packaging structure 500, thereby facilitating the packaging and securing of products using the folded packaging structure 500. In this embodiment, the product packaged by the packaging structure 500 can be a charger with a cable, other electronic products with cables, etc., and is not limited thereto.

[0054] Please refer to the reference. Figures 1 to 6 As shown, in this embodiment of the invention, the packaging cardboard 100 includes a base plate 1, a cover plate 2, and a limiting plate 3. The base plate 1 is provided with a snap-fit ​​part 11 and has adjacent first side 12 and second side 13. The cover plate 2 is connected to the first side 12, and a crease is formed at the connection between the cover plate 2 and the first side 12. The cover plate 2 is folded relative to the base plate 1 to form an accommodating space 4. The cover plate 2 is also provided with an installation opening 211 communicating with the accommodating space 4. The limiting plate 3 is connected to the second side 13, and a crease is formed at the connection between the limiting plate 3 and the second side 13. The limiting plate 3 is provided with a snap-fit ​​part 321. The limiting plate 3 is folded relative to the base plate 1 so that the snap-fit ​​part 321 is connected to the snap-fit ​​part 11 to cover the cover plate 2.

[0055] In this embodiment, the base plate 1, cover plate 2, and limiting plate 3 of the packaging cardboard 100 are integrally formed or integrally connected. The base plate 1 is generally rectangular (square or rectangular shape), and has adjacent first side 12 and second side 13, that is, the first side 12 and the second side 13 are connected to form an L-shape. The cover plate 2 and the limiting plate 3 are integrally connected to the first side 12 and the second side 13 of the base plate 1, respectively. At this time, the cover plate 2 is integrally connected to the base plate 1, and the limiting plate 3 is integrally connected to the base plate 1. When the packaging cardboard 100 is laid flat, there is no connection between the cover plate 2 and the limiting plate 3.

[0056] Understandably, to facilitate folding, a crease is formed at the connection between the cover plate 2 and the first side 12 of the base plate 1, and a crease is formed at the connection between the limiting plate 3 and the second side 13 of the base plate 1. That is, when the cover plate 2 is folded relative to the base plate 1, the cover plate 2 can rotate around the crease on the first side 12 relative to the base plate 1, so that the cover plate 2 and the base plate 1 enclose and form an accommodating space 4. When the limiting plate 3 is folded relative to the base plate 1, the limiting plate 3 can rotate around the crease on the second side 13 relative to the base plate 1, so that the limiting plate 3 can cover the cover plate 2, and is connected and fixed by the snap-fit ​​part 321 and the buckle part 11. At the same time, the limiting plate 3 further improves the connection stability between the cover plate 2 and the base plate 1.

[0057] Optionally, the shape of the accommodating space 4 can be a regular rectangle (cuboid or cube) or an irregular shape, depending on the shape and structure of the cover plate 2, and is not limited here.

[0058] In this embodiment, the cover plate 2 is optionally generally rectangular (rectangular or square), such that the accommodating space 4 formed after the cover plate 2 is folded relative to the base plate 1 is rectangular (cubic or cubic). Optionally, after the cover plate 2 is folded relative to the base plate 1, the projection of the cover plate 2 onto the base plate 1 matches the shape and outline of the base plate 1. It can be understood that the limiting plate 3 is optionally generally rectangular (rectangular or square), such that after the limiting plate 3 is folded relative to the base plate 1, it can cover the top of the cover plate 2.

[0059] It should be noted that products with cables include the product body and the cable. One end of the cable is connected to the product body, and the other end of the cable has a connector or other structure, which is not limited here. When a product with a cable is assembled into a packaging structure 500 formed by folding packaging cardboard 100, the product body is housed in the housing space 4 of the packaging structure 500 through the mounting port 211 on the cover plate 2. The cable extends out of the housing space 4 from the mounting port 211 and surrounds the outer perimeter of the housing space 4 formed by the cover plate 2 and the bottom plate 1. Finally, the connector and other structures at the other end of the cable are further confined within the housing space 4. Then, the limiting plate 3 is folded and covers the top of the cover plate 2, thereby covering and pressing the connector and other structures of the cable. This reduces the volume of the packaging structure 500 formed by folding packaging cardboard 100 and improves the efficiency of product assembly. The cable is placed around the perimeter of the outer wall of the housing space 4, which better shows the effect of the smooth winding. Furthermore, the connection between the snap-fit ​​part 321 and the snap-fit ​​part 11 makes the packaging structure 500 less prone to loosening due to the snap-fit ​​fixing structure. It is formed in one piece, with a complete structure, combining functionality and aesthetics.

[0060] The packaging cardboard 100 of the present invention provides a snap-fit ​​part 11 on the base plate 1, and connects the cover plate 2 and the limiting plate 3 to the adjacent first side 12 and second side 13 of the base plate 1. This results in a crease at the connection between the cover plate 2 and the first side 12, and a crease at the connection between the limiting plate 3 and the second side 13. The limiting plate 3 also has a snap-fit ​​part 321. Thus, after the cover plate 2 is folded relative to the base plate 1, the cover plate 2 and the base plate 1 enclose a receiving space 4. The cover plate 2 also has an installation port 211 communicating with the receiving space 4, allowing products to be conveniently placed into the receiving space 4 through the installation port 211 for product storage. Simultaneously, the product's cables can extend out of the receiving space 4 through the installation port 211. The cable is neatly wrapped around the perimeter of the outer wall of the accommodating space 4. After the limiting plate 3 is folded relative to the bottom plate 1, it is connected to the buckle part 11 by the snap-fit ​​part 321 to achieve the connection and fixation between the limiting plate 3 and the bottom plate 1. At the same time, the limiting plate 3 covers the covering plate 2, thereby keeping the cable neatly positioned around the perimeter of the outer wall of the accommodating space 4. The packaging structure 500 formed by folding the packaging cardboard 100 is not easy to loosen with the snap-fit ​​fixation structure. It is formed in one piece of paper, with a complete structure, combining functionality and aesthetics. At the same time, it only forms the accommodating space 4 for placing products, thereby effectively reducing the volume of the packaging structure 500. Moreover, the cable is wrapped around the perimeter of the outer wall of the accommodating space 4, which can better show the effect of the neat winding.

[0061] In one embodiment, the limiting plate 3 is provided with an avoidance opening 313. After the limiting plate 3 is folded relative to the bottom plate 1, the avoidance opening 313 is directly connected to the mounting opening 211.

[0062] In this embodiment, as Figures 1 to 5 As shown, by providing an clearance opening 313 on the limiting plate 3, when the packaging cardboard 100 is folded to form the packaging structure 500, and the limiting plate 3 covers the top of the cover plate 2, the clearance opening 313 is directly connected to the mounting opening 211. It can be understood that the clearance opening 313 is provided to facilitate the clearance of the product body placed in the accommodating space 4.

[0063] Of course, in other embodiments, a viewing area can also be provided on the limiting plate 3. After the limiting plate 3 is folded relative to the base plate 1, the viewing area is directly opposite the mounting opening 211. It is understood that the viewing area can be a transparent window structure. For example, an avoidance opening 313 can be provided on the limiting plate 3, and a transparent material structure can be provided at the avoidance opening 313 to cover the avoidance opening 313. This can both seal the accommodating space 4 and allow the user to easily view the product body placed in the accommodating space 4 through the viewing area.

[0064] In one embodiment, the cover plate 2 includes a main cover plate 21 and a first side plate 22. One side of the main cover plate 21 is connected to the first side edge 12. The main cover plate 21 is provided with an installation opening 211. The main cover plate 21 also has a first crease 212 near the first side edge 12. The first side plate 22 includes a first segment 221 and an adhesive segment 222 connected to each other. A crease is formed at the connection between the first segment 221 and the adhesive segment 222. The side of the first segment 221 away from the adhesive segment 222 is connected to the main cover plate 21 and has a crease. When the cover plate 2 is folded relative to the bottom plate 1, the adhesive segment 222 is connected to the side of the bottom plate 1 away from the first side edge 12, so that the bottom plate 1, the first segment 221, and the main cover plate 21 enclose and form an accommodating space 4.

[0065] In this embodiment, as Figures 1 to 3 As shown, by setting the cover plate 2 as the main cover plate 21 and the first side plate 22, the bottom plate 1 and the first side plate 22 are located on opposite sides of the main cover plate 21. A first crease 212 is also formed near the first side 12 of the main cover plate 21, and a crease is formed at the connection between the first segment 221 and the adhesive segment 222. A crease is formed at the connection between the first segment 221 and the main cover plate 21. In this way, after the cover plate 2 is folded relative to the bottom plate 1, the bottom plate 1, the first segment 221, the main cover plate 21, and the part between the first crease 212 and the first side 12 can be enclosed to form an accommodating space 4.

[0066] Understandably, the cover plate 2 is connected to the side of the base plate 1 away from the first side 12 via the adhesive section 222 to fix the cover plate 2 to the base plate 1. Optionally, the adhesive section 222 is coated with an adhesive layer, and the adhesive section 222 is connected to the base plate 1 via the adhesive layer. Of course, in other embodiments, one of the adhesive section 222 and the side of the base plate 1 away from the first side 12 may be provided with a fastener, and the other may be provided with a snap-fit ​​element, thereby achieving a detachable connection by utilizing the cooperation of the fastener and the snap-fit ​​element, which is not limited here.

[0067] Optionally, the width of the first segment 221 is the same as the distance from the first side 12 to the first crease 212. In this embodiment, the width of the first segment 221 is the distance between the main cover plate 21 and the adhesive segment 222. Setting the width of the first segment 221 and the distance from the first side 12 to the first crease 212 to be the same ensures that after the cover plate 2 is folded, the main cover plate 21 is opposite to and parallel to the bottom plate. Optionally, when the cover plate 2 is folded relative to the bottom plate 1, the projected area of ​​the cover plate 2 is equal to the projected area of ​​the bottom plate 1. This can improve the appearance of the packaging structure 500 and reduce its volume.

[0068] To further improve the stability of the connection between the cover plate 2 and the base plate and ensure the stability of the formed accommodating space 4, in one embodiment, the cover plate 2 further includes a second side plate 23 and a third side plate 24. The second side plate 23 includes a second segment 231 and a first abutting segment 232 connected together. A crease is formed at the connection between the second segment 231 and the first abutting segment 232. The side of the second segment 231 away from the first abutting segment 232 is connected to one side of the main cover plate 21 and forms a crease. The second side plate 23 and the third side plate 24 are located on opposite sides of the main cover plate 21 and between the first side 12 and the first side plate 22. The third side plate 24 includes a third segment 241 and a second abutting segment 242 connected together. A crease is formed at the connection between the third segment 241 and the second abutting segment 242. The side of the third segment 241 away from the second abutting segment 242 is connected to one side of the main cover plate 21 and forms a crease.

[0069] Understandably, when the main cover 21 is folded relative to the base plate 1, the first abutting section 232 and the second abutting section 242 abut against the opposite sides of the base plate 1 respectively, so that the second section 231 is located between the second side 13 and the main cover 21, and the second section 231 and the third section 241 are opposite to each other, and together with the base plate 1, the first section 221 and the main cover 21, they form an accommodating space 4.

[0070] In this embodiment, as Figures 1 to 3 As shown, by setting the second side plate 23 and the third side plate 24, after the cover plate 2 is folded relative to the bottom plate 1, it can be connected or abutted to the bottom plate 1 by using the first abutting section 232 of the second side plate 23 and the second abutting section 242 of the third side plate 24. It can also use the second section 231 of the second side plate 23 and the third section 241 of the third side plate 24 in conjunction with the first section 221 and the part between the first side 12 and the first crease 212 to support and fix the cover plate 21, thereby improving stability.

[0071] It is understandable that the first abutting section 232 of the second side plate 23 and / or the second abutting section 242 of the third side plate 24 can be connected to the base plate 1 by adhesive, or a detachable connection structure can be provided to achieve a detachable connection, which is not limited here.

[0072] In this embodiment, the width of the second segment 231 may optionally be the same as the width of the third segment 241. To ensure that the accommodating space 4 formed after the cover plate 2 is folded has a regular shape, optionally, the widths of the second segment 231 and the third segment 241 are the same as the width of the first segment 221, and the widths of the second segment 231 and the third segment 241 are the same as the width of the snap-fit ​​plate 14. It can be understood that this ensures that after the cover plate 2 is folded, the main cover plate 21 and the base plate 1 are arranged opposite to each other and parallel.

[0073] To further improve the connection stability between the cover plate 2 and the base plate 1, and to improve the sealing performance of the accommodating space 4, in one embodiment, such as Figure 1 As shown, the main cover 21 is also provided with two first side ears 214 near the first side 12. The two first side ears 214 are arranged opposite each other and are located between the first side 12 and the first crease 212. When the main cover 21 is folded relative to the base plate 1, the two first side ears 214 abut against the second section 231 and the third section 241 respectively.

[0074] Of course, the first side plate 22 also includes two second side ears 223. The two second side ears 223 are connected to the opposite sides of the first section 221 and are located between the cover plate 21 and the adhesive section 222. When the cover plate 21 is folded relative to the bottom plate 1, the two second side ears 223 abut against the second section 231 and the third section 241 respectively.

[0075] In one embodiment, a locking hole 243 is formed at the connection between the main cover plate 21 and the third side plate 24, and the bottom plate 1 is also provided with a locking plate 14 opposite to the second side 13. A crease is formed at the connection between the locking plate 14 and the bottom plate 1, and the locking plate 14 is provided with a locking ear 15. The main cover plate 21 is folded relative to the bottom plate 1, and the locking plate 14 is folded relative to the bottom plate 1 so that the locking ear 15 is engaged in the locking hole 243.

[0076] In this embodiment, as Figures 1 to 3 As shown, by setting a snap-fit ​​plate 14 on the base plate 1 and a snap-fit ​​ear 15 on the snap-fit ​​plate 14, and forming a snap-fit ​​hole 243 at the connection between the main cover plate 21 and the third side plate 24, a crease is formed at the connection between the snap-fit ​​plate 14 and the base plate 1. After the cover plate 2 is folded relative to the base plate 1, the snap-fit ​​plate 14 is folded relative to the base plate 1, so that the snap-fit ​​ear 15 is snapped into the snap-fit ​​hole 243, thereby further improving the connection stability between the base plate 1 and the cover plate 2.

[0077] Understandably, the snap-fit ​​plate 14 and the limiting plate 3 are located on opposite sides of the base plate 1. Optionally, the width of the snap-fit ​​plate 14 is equal to or greater than the width of the first segment 221, the portion between the first side 12 and the first crease 212, the second segment 231, and the third segment 241. The width of the snap-fit ​​plate 14 is the distance between the side of the snap-fit ​​plate 14 away from the base plate 1 and the side connected to the base plate 1.

[0078] In this embodiment, to facilitate the engagement of the latch 15 into the latch hole 243, the second segment 231 is also provided with an elastic ear 244 adjacent to the latch hole 243. Thus, when the latch 15 is inserted into the latch hole 243, the elastic ear 244 provides elasticity or avoidance for the latch 15.

[0079] In one embodiment, such as Figures 1 to 3As shown, the main cover 21 also has a connecting port 213, which connects the mounting port 211 and the snap-fit ​​hole 243. Understandably, by setting the connecting port 213, the cables of the product in the accommodating space 4 can easily extend out of the accommodating space 4 through the connecting port 213, thereby wrapping around the outside of the first segment 221, the portion between the first side 12 and the first crease 212, the second segment 231, and the third segment 241. Finally, the plug structure of the cable is snapped into place within the accommodating space 4 through the connecting port 213, which can not only fix the cable, but also improve the aesthetics after assembly.

[0080] In one embodiment, the limiting plate 3 includes a pressure plate portion 31 and a support portion 32 connected together. A crease is formed at the connection between the pressure plate portion 31 and the support portion 32. The side of the pressure plate portion 31 away from the support portion 32 is connected to the second side 13 and has a crease. The support portion 32 is provided with a snap-fit ​​portion 321. When the limiting plate 3 is folded relative to the bottom plate 1, the pressure plate portion 31 covers the side of the cover plate 2 facing away from the bottom plate 1, and the support portion 32 covers the side of the bottom plate 1 facing away from the cover plate 2, so that the snap-fit ​​portion 321 is connected to the buckle portion 11.

[0081] In this embodiment, as Figures 1 to 6 As shown, by setting the limiting plate 3 into two parts, a pressure plate part 31 and a support part 32, the limiting plate 3, after being folded, covers the side of the cover plate 2 facing away from the bottom plate 1 with the pressure plate part 31, and the support part 32 covers the side of the bottom plate 1 facing away from the cover plate 2, so that the snap-fit ​​part 321 is connected to the snap-fit ​​part 11, thereby further improving the packaging structure 500 formed after the packaging paperboard 100 is folded, making it more stable, less prone to loosening, formed in one piece, structurally complete, and combining functionality and aesthetics.

[0082] Understandably, a crease is formed at the connection between the pressure plate portion 31 and the support portion 32, and a crease is formed at the connection between the pressure plate portion 31 and the second side 13. A second crease 311 is formed on the side of the pressure plate portion 31 adjacent to the second side 13, and a third crease 312 is formed on the side of the pressure plate portion 31 adjacent to the support portion 32. In this way, the pressure plate portion 31 and the support portion 32 can be completely covered on the outside of the cover plate 21 and the base plate 1, further improving stability and aesthetics.

[0083] Optionally, the distance from the second crease 311 to the second side 13 is greater than or equal to the width of the snap-fit ​​plate 14. The distance from the second crease 311 to the second side 13 is greater than or equal to the width of the first segment 221, the portion between the first side 12 and the first crease 212, the second segment 231, and the third segment 241.

[0084] In this embodiment, after the limiting plate 3 is folded relative to the base plate 1, the projected area of ​​the pressure plate portion 31 is smaller than the projected area of ​​the support portion 32. With this arrangement, the support portion 32 can be used to limit the cable placed outside the accommodating space 4, preventing the cable from slipping off from the first section 221, the portion between the first side 12 and the first crease 212, the second section 231, and the outer side of the third section 241 of the cover plate 2.

[0085] Optionally, the cover plate 2 is folded relative to the base plate 1, and after the limiting plate 3 is folded relative to the base plate 1, the projected area of ​​the pressure plate portion 31 is equal to the projected area of ​​the cover plate 2.

[0086] like Figure 5 and Figure 6 As shown, the present invention also proposes a packaging structure 500, which is formed by folding the aforementioned packaging cardboard 100. The specific structure of the packaging cardboard 100 is as described in the foregoing embodiments. Since this packaging structure adopts all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be described in detail here.

[0087] In this embodiment, the packaging structure 500 has a receiving space 4 and an opening communicating with the receiving space 4. The opening is formed by the mounting port 211 of the cover plate 2 and the clearance port 313 of the pressure plate portion 31 of the limiting plate 3, which are directly connected and cooperate. It can be understood that the plane where the opening is located is defined as the front, and the side of the packaging structure 500 opposite to the front is defined as the back. The packaging structure 500 has a limiting edge on the periphery of the back. The limiting edge is formed by extending from the periphery of the support portion 32 of the limiting plate 3. In this way, the limiting edge can be used to limit the cable wrapped around the outer periphery of the receiving space 4.

[0088] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
