Description

Technical Field

[0001] This application belongs to the field of product packaging technology, specifically relating to a packaging structure and packaging box. Background Technology

[0002] Packaging boxes are inevitably used in the transportation of goods. Typically, a packaging box consists of a box body and a cushioning structure inside the box body to provide cushioning. The box body and the cushioning structure work together to effectively prevent damage to the goods.

[0003] However, traditional packaging boxes still have some drawbacks. The most significant one is that the box body and cushioning structure are often made of foam, which is difficult to degrade and easily causes environmental pollution, resulting in poor environmental performance of the packaging boxes. Utility Model Content

[0004] The purpose of this application is to provide a packaging structure and packaging box that can solve the problem of poor environmental performance of packaging boxes in related technologies.

[0005] In a first aspect, embodiments of this application provide a packaging structure, including at least one of a first paper card and a second paper card, wherein the first paper card is used to fold to form a box body of a packaging box, and the second paper card is used to fold to form a cushioning structure of the packaging box; The first paper card includes a side panel with a through hole. When the first paper card is folded, the side panel forms the perimeter wall of the box, and the through hole is used to take out and put in the cable of the item inside the box. The second paper card includes a first cover plate, a first side plate, a second cover plate, and a second side plate connected in sequence, and the second cover plate is provided with a through hole; when the second paper card is in a folded state, the first cover plate and the second cover plate are arranged opposite to each other in a first direction to form the top wall and bottom wall of the buffer structure respectively, and the through hole is used to take out and put in the items in the buffer structure. The first side plate and the second side plate are arranged opposite to each other in a second direction perpendicular to the first direction to form part of the side wall of the buffer structure, and the first cover plate and the second side plate are engaged.

[0006] Secondly, embodiments of this application provide a packaging box, including a box body and a cushioning structure, wherein the cushioning structure is disposed within the box body, wherein: The box body is formed by folding the first paper card of the packaging structure described above. The box body has the through hole on its peripheral side wall, which is used to take out and put in the cable of the item inside the box. And / or, the cushioning structure is formed by folding the second paper card of the packaging structure described above.

[0007] In this embodiment of the application, the packaging structure includes at least one of a first paper card and a second paper card. The first paper card is used to fold to form a box body, and the second paper card is used to fold to form a cushioning structure. In this way, at least one of the box body and the cushioning structure is made of paper material, which is easy to degrade, thereby improving the environmental friendliness of the packaging box.

[0008] Furthermore, when the first card is folded, the side panels form the perimeter walls of the box, and the through holes are used to access the cables of items inside the box. This allows at least a portion of the cables to be removed without opening the box, enabling electrical connection of the cables to other components for testing. This setup eliminates the need to open the box, allowing users to test items more quickly.

[0009] Furthermore, the second paper card includes a first cover plate, a first side plate, a second cover plate, and a second side plate connected in sequence. When the second paper card is in a folded state, the first cover plate and the second cover plate are positioned opposite each other in a first direction to form the top and bottom walls of the buffer structure, respectively. The first side plate and the second side plate are positioned opposite each other in a second direction perpendicular to the first direction to form part of the side walls of the buffer structure, and the first cover plate and the second side plate are engaged in a snap-fit ​​configuration. In this configuration, the first cover plate, the first side plate, the second cover plate, and the second side plate can maintain their respective shapes by means of the snap-fit ​​configuration. The snap-fit ​​configuration is relatively simple to operate, thereby improving the processing efficiency of the buffer structure. Moreover, the snap-fit ​​configuration allows for repeated assembly and disassembly, which facilitates the reuse of the second paper card. Attached Figure Description

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0014] The packaging structure and packaging box provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0015] Please refer to Figures 1 to 7 As shown in the embodiment of this application, a packaging structure is provided, including at least one of a first paper card 100 and a second paper card 200. That is, the packaging structure may include either the first paper card 100 or the second paper card 200, or may include both the first paper card 100 and the second paper card 200.

[0016] The first paper card 100 is used to fold and form the box body 300 of the packaging box, and the second paper card 200 is used to fold and form the cushioning structure 400 of the packaging box.

[0017] The first paper card 100 includes a side panel 110, which has a through hole 1121. When the first paper card 100 is in a folded state, that is, when the first paper card 100 is folded to form a box 300, the side panel 110 surrounds and forms the peripheral side wall of the box 300, and the through hole 1121 is used to take out and put in the cable of the item inside the box 300.

[0018] The second paper card 200 includes a first cover plate 210, a first side plate 220, a second cover plate 230, and a second side plate 240 connected in sequence, and the second cover plate 230 has a through hole 231. When the second paper card 200 is in a folded state, that is, when the second paper card 200 is folded to form a buffer structure 400, the first cover plate 210 and the second cover plate 230 are arranged opposite to each other in a first direction to form the top wall and bottom wall of the buffer structure 400, respectively, and the through hole 231 is used to take out and put in items inside the buffer structure 400. The first side plate 220 and the second side plate 240 are arranged opposite to each other in a second direction perpendicular to the first direction to form part of the side wall of the buffer structure 400, and the first cover plate 210 and the second side plate 240 are engaged. The first direction is, for example, Figure 5 The direction indicated by arrow A in the diagram, the second direction is, for example, Figure 5 The direction indicated by arrow B in the diagram.

[0019] In this embodiment of the application, the packaging structure includes at least one of a first paper card 100 and a second paper card 200. The first paper card 100 is used to fold to form a box body 300, and the second paper card 200 is used to fold to form a cushioning structure 400. In this way, at least one of the box body 300 and the cushioning structure 400 is made of paper material, which is easy to degrade, thereby improving the environmental friendliness of the packaging box.

[0020] Furthermore, when the first card 100 is folded, the side panel 110 forms the perimeter wall of the box 300, and the through hole 1121 is used to retrieve and place the cable of the item inside the box 300. In this way, using the through hole 1121, at least a portion of the cable can be removed without opening the box 300. The cable can then be electrically connected to other components to perform the corresponding tests on the item. With this configuration, since the time spent opening the box 300 is eliminated, the user can test the item relatively quickly.

[0021] Furthermore, the second paper card 200 includes a first cover plate 210, a first side plate 220, a second cover plate 230, and a second side plate 240 connected in sequence. When the second paper card 200 is in a folded state, the first cover plate 210 and the second cover plate 230 are arranged opposite each other in a first direction to form the top and bottom walls of the buffer structure 400, respectively. The first side plate 220 and the second side plate 240 are arranged opposite each other in a second direction perpendicular to the first direction to form part of the side walls of the buffer structure 400, and the first cover plate 210 and the second side plate 240 are engaged. In this arrangement, by means of the engagement of the first cover plate 210 and the second side plate 240, the first cover plate 210, the first side plate 220, the second cover plate 230, and the second side plate 240 can maintain their respective shapes. The engagement method is relatively simple to operate, thereby improving the processing efficiency of the buffer structure 400. Moreover, the engagement method can be repeatedly disassembled and reassembled, which helps the second paper card 200 to be reused.

[0022] Furthermore, during the warehousing and transportation stages, the first paper card 100 and the second paper card 200 provided in this embodiment can be in a flattened state, which can reduce space occupation and thus reduce warehousing and transportation costs.

[0023] In one specific implementation, the item placed in the packaging box is, for example, an electronic device, which includes a device body and a cable. One end of the cable is electrically connected to the device body. The user can remove the other end of the cable from the box 300 through the through hole 1121, and then electrically connect the other end of the cable to other devices, thereby enabling rapid testing of the electronic device without disassembling the box 300.

[0024] In another embodiment, reference Figure 1 and Figure 3As shown, the first paper card 100 also includes a baffle 140, which is foldably connected to the side panel 110, meaning the position of the baffle 140 relative to the side panel 110 is adjustable. When the first paper card 100 is in the folded state, the baffle 140 is located within the through hole 1121, and an operating space 150 is formed between the baffle 140 and the edge of the through hole 1121. Specifically, the baffle 140 is connected to a portion of the edge of the through hole 1121, and an operating space 150 is formed between the baffle 140 and another portion of the edge of the through hole 1121. Optionally, the operating space 150 can be a U-shaped space.

[0025] In this embodiment, when the first paper card 100 is in a folded state, the baffle 140 can block part of the through hole 1121, thereby reducing the probability of external impurities entering the box 300 through the through hole 1121.

[0026] Furthermore, in actual use, when it is necessary to remove at least a portion of the cable from the housing 300, the cover plate 140 needs to be folded beforehand so that at least a portion of the cover plate 140 can be moved out of the through hole 1121. The design of the operating space 150 provides space for the user's hand to fold the cover plate 140, which reduces the difficulty of folding the cover plate 140. In this way, the user can more conveniently test the items inside the housing 300.

[0027] In other embodiments, the first paper card 100 may not include the baffle 140, or the first paper card 100 may include the baffle 140, but no operating space 150 is provided between the baffle 140 and the edge of the through hole 1121. In this case, the shape of the baffle 140 may be adapted to the shape of the through hole 1121.

[0028] As one specific implementation method, refer to Figure 1 and Figure 3 As shown, the side panel 110 includes, for example, a first sub-panel 111, a second sub-panel 112, a third sub-panel 113, and a fourth sub-panel 114 connected in sequence. When the first card 100 is in a folded state, the first sub-panel 111 and the third sub-panel 113 are arranged opposite each other in a fourth direction, and the second sub-panel 112 and the fourth sub-panel 114 are arranged opposite each other in a fifth direction to obtain a box 300 of a corresponding shape. The fourth direction is, for example, Figure 3 The direction indicated by arrow C in the image, for example, is the fifth direction. Figure 3 As indicated by arrow D in the diagram, at least one of the first sub-plate 111, the second sub-plate 112, the third sub-plate 113, and the fourth sub-plate 114 is provided with a through hole 1121. Figure 1 In the middle, through hole 1121 is provided on the second sub-plate 112.

[0029] Further, refer to Figure 1As shown, the first paper card 100 also includes a seventh abutment plate 115, which is connected to the side of the first sub-plate 111 away from the second sub-plate 112. When the first paper card 100 is in a folded state, the seventh abutment plate 115 abuts against the side of the fourth sub-plate 114 facing the second sub-plate 112. With this arrangement, the first sub-plate 111 cooperates with the fourth sub-plate 114 through the seventh abutment plate 115. In this way, the first sub-plate 111 and the fourth sub-plate 114 are not easy to move relative to each other, thereby improving the stability of the box 300.

[0030] Further, refer to Figure 1 and Figure 3 As shown, the first paper card 100 also includes a first mating plate 121, a second mating plate 122, a third mating plate 123, and a fourth mating plate 124. When the first paper card 100 is in a flattened state, the first mating plate 121, the second mating plate 122, the third mating plate 123, and the fourth mating plate 124 are located on the same side of the side panel 110. The first mating plate 121 is foldably connected to one side of the first sub-plate 111, and a slot 1211 is provided on the side of the first mating plate 121 away from the first sub-plate 111. The second mating plate 122 is foldably connected to one side of the second sub-plate 112. The third mating plate 123 is foldably connected to one side of the third sub-plate 113. The fourth mating plate 124 is foldably connected to one side of the fourth sub-plate 114.

[0031] refer to Figure 4 As shown, when the first card 100 is in a folded state, a portion of the third mating plate 123 passes through the slot 1211 of the first mating plate 121 and is pressed against the inner side of the first mating plate 121. A portion of the second mating plate 122 and a portion of the fourth mating plate 124 are pressed against the outer side of the first mating plate 121, while the remaining portions are pressed against the inner side of the third mating plate 123, so that the box body 300 maintains its corresponding shape. Furthermore, the first mating plate 121, the second mating plate 122, the third mating plate 123, and the fourth mating plate 124 together form the bottom wall of the box body 300.

[0032] Further, refer to Figure 1 and Figure 3 As shown, the first paper card 100 also includes a third cover plate 131, a fifth mating plate 132, and a sixth mating plate 133. The third cover plate 131 is foldably connected to the side of the first sub-plate 111 away from the first mating plate 121, the fifth mating plate 132 is foldably connected to the side of the second sub-plate 112 away from the second mating plate 122, and the sixth mating plate 133 is foldably connected to the side of the fourth sub-plate 114 away from the fourth mating plate 124.

[0033] refer to Figure 3As shown, when the first card 100 is in a folded state, the third cover plate 131 forms the top wall of the box 300, and the third cover plate 131 covers the outside of the fifth mating plate 132 and the sixth mating plate 133. With this arrangement, the second sub-plate 112 engages with the third cover plate 131 through the fifth mating plate 132, and the fourth sub-plate 114 engages with the third cover plate 131 through the sixth mating plate 133. In this way, the second sub-plate 112 and the fourth sub-plate 114 are not easily moved relative to the third cover plate 131, thereby improving the stability of the box 300.

[0034] Seeking further information Figure 1 and Figure 3 As shown, the first paper card 100 also includes a seventh mating plate 134 and a second locking plate 1131. The seventh mating plate 134 is foldably connected to the side of the third cover plate 131 away from the first sub-plate 111, and a second mating hole 1341 is provided on the side of the seventh mating plate 134 near the third cover plate 131. The third sub-plate 113 is provided with the second locking plate 1131. When the first paper card 100 is in a folded state, the second locking plate 1131 engages with the second mating hole 1341 to fix the third cover plate 131. With this arrangement, fixing the third cover plate 131 will not damage its integrity, thus ensuring its strength and giving it good sealing performance.

[0035] Furthermore, refer to Figure 1 and Figure 3 As shown, the third sub-plate 113 has a movable sub-plate 1132, which is part of the third sub-plate 113 and can be folded relative to another part of the third sub-plate 113. The second latching plate 1131 is foldably connected to the movable sub-plate 1132. In this configuration, the position of the second latching plate 1131 relative to the movable sub-plate 1132 is adjustable, and the position of the movable sub-plate 1132 relative to other parts of the third sub-plate 113 is also adjustable, thus giving the second latching plate 1131 a high degree of flexibility. This makes it easier to move the second latching plate 1131 out of the second mating hole 1341, thereby reducing the difficulty of opening the third cover plate 131.

[0036] Further, refer to Figure 1 and Figure 3 As shown, the third cover plate 131 has a first notch 1311 on the side near the seventh mating plate 134. When the first locking plate 232 is in the folded state, the first notch 1311 is positioned opposite to the second locking plate 1131. With this configuration, the user's hand can directly act on the second locking plate 1131 through the first notch 1311, which also makes it easy to remove the second locking plate 1131 from the second mating hole 1341.

[0037] In another embodiment, reference Figure 2 As shown, the second paper card 200 also includes a third side plate 250, a fourth side plate 260, a first abutting plate 271 and a second abutting plate 272, which are connected in sequence.

[0038] When the second paper card 200 is in a folded state, the third side plate 250 and the fourth side plate 260 are arranged opposite each other in a third direction that is perpendicular to both the first and second directions, to form part of the sidewall of the buffer structure 400. The first abutting plate 271 and the second abutting plate 272 are both stacked on the side of the first cover plate 210 facing the second cover plate 230, and the third side plate 250 abuts against the first cover plate 210 through the first abutting plate 271, and the fourth side plate 260 abuts against the first cover plate 210 through the second abutting plate 272.

[0039] In this embodiment, the third side plate 250 abuts against the first cover plate 210 via the first abutting plate 271. Under the action of the abutting force between the first abutting plate 271 and the first cover plate 210, the third side plate 250 is held in the corresponding position, thereby achieving its own fixation. This fixing method is relatively convenient to operate, thereby improving the processing efficiency of the buffer structure 400. In addition, this fixing method has virtually no impact on the structure of the second paper card 200, thus also contributing to the reuse of the second paper card 200.

[0040] Furthermore, the fourth side plate 260 abuts against the first cover plate 210 via the second abutting plate 272. Under the action of the abutting force between the second abutting plate 272 and the first cover plate 210, the fourth side plate 260 is held in the corresponding position, thereby achieving its own fixation. The fixing method of the fourth side plate 260 is essentially the same as that of the third side plate 250. The fixing method of the fourth side plate 260 also improves the processing efficiency of the buffer structure 400 and facilitates the reuse of the second paper card 200.

[0041] Seeking further information Figure 2 and Figure 6 As shown, the two opposite edges of the first cover plate 210 are provided with second notches 211. When the second paper card 200 is in a folded state, the two second notches 211 are respectively positioned opposite to the first abutting plate 271 and the second abutting plate 272.

[0042] In actual use, the second notch 211 allows the user's hand to directly act on the first abutment plate 271 and the second abutment plate 272, facilitating the offsetting of the first abutment plate 271 and the second abutment plate 272 from the first cover plate 210, thereby reducing the difficulty of assembling and disassembling the buffer structure 400. Additionally, during the initial processing stage, the second notch 211 can also assist in positioning the second paper card 200, thus reducing the processing difficulty of the second paper card 200.

[0043] In other embodiments, the second paper card 200 may not include the first abutment plate 271 and the second abutment plate 272, or it may include only one of the first abutment plate 271 and the second abutment plate 272. When the second paper card 200 does not include the first abutment plate 271, the third side plate 250 is, for example, directly adhered to the first cover plate 210; when the second paper card 200 does not include the second abutment plate 272, the fourth side plate 260 is, for example, directly adhered to the second cover plate 230.

[0044] In another embodiment, reference Figure 2 , Figure 5 as well as Figure 7 As shown, the second paper card 200 also includes a third abutment plate 273 and a fourth abutment plate 274, which are respectively connected to opposite sides of the first side plate 220. When the second paper card 200 is in a folded state, the third abutment plate 273 abuts against the side of the third side plate 250 facing the fourth side plate 260, and the fourth abutment plate 274 abuts against the side of the fourth side plate 260 facing the third side plate 250.

[0045] In this embodiment, the first side plate 220 cooperates with the third side plate 250 through the third abutting plate 273. Under the abutting action of the third abutting plate 273 and the third side plate 250, the first side plate 220 and the third side plate 250 are not easy to move relative to each other, thereby improving the stability of the buffer structure 400.

[0046] Similarly, refer to Figure 7 As shown, the first side plate 220 cooperates with the fourth side plate 260 through the fourth abutting plate 274. Under the abutting action of the fourth abutting plate 274 and the fourth side plate 260, the first side plate 220 and the fourth side plate 260 are not easy to move relative to each other, which also improves the stability of the buffer structure 400.

[0047] In other embodiments, the second paper card 200 may not include the third abutment plate 273 and the fourth abutment plate 274, or the second paper card 200 may include only one of the third abutment plate 273 and the fourth abutment plate 274.

[0048] In another embodiment, reference Figure 2 and Figure 5 As shown, the second paper card 200 also includes a fifth abutment plate 275 and a sixth abutment plate 276. The fifth abutment plate 275 and the sixth abutment plate 276 are respectively connected to opposite sides of the second side plate 240. When the second paper card 200 is in a folded state, the fifth abutment plate 275 abuts against the side of the third side plate 250 facing the fourth side plate 260, and the sixth abutment plate 276 abuts against the side of the fourth side plate 260 facing the third side plate 250.

[0049] In this embodiment, the second side plate 240 cooperates with the third side plate 250 through the fifth abutment plate 275. Under the abutment action of the fifth abutment plate 275 and the third side plate 250, the second side plate 240 and the third side plate 250 are not easy to move relative to each other, thereby improving the stability of the buffer structure 400.

[0050] Similarly, the second side plate 240 cooperates with the fourth side plate 260 through the sixth abutment plate 276. Under the abutment action of the sixth abutment plate 276 and the fourth side plate 260, the second side plate 240 and the fourth side plate 260 are not easy to move relative to each other, thereby also improving the stability of the buffer structure 400.

[0051] In other embodiments, the second paper card 200 may not include the fifth abutment plate 275 and the sixth abutment plate 276, or the second paper card 200 may include only one of the fifth abutment plate 275 and the sixth abutment plate 276.

[0052] In another embodiment, reference Figure 2 and Figure 5 As shown, the second paper card 200 also includes a first limiting plate 281. The first limiting plate 281 is connected to the first edge 2311 of the through hole 231. When the second paper card 200 is in a folded state, the first limiting plate 281 is located inside the through hole 231 and is coplanar with the second cover plate 230.

[0053] The second paper card 200 also includes a second limiting plate 282. The second limiting plate 282 is foldably connected to the side of the first limiting plate 281 away from the first edge 2311 and is provided with a locking hole 2821. When the second paper card 200 is in the folded state, the second limiting plate 282 is located on the side of the first limiting plate 281 facing the first cover plate 210 and is perpendicular to the first limiting plate 281. The locking hole 2821 is used to allow a part of the article to extend between the first limiting plate 281 and the first cover plate 210 and to engage with the article.

[0054] In this embodiment, the locking hole 2821 engages with the item, which restricts the movement of the item and improves its stability, thereby reducing the probability of damage.

[0055] Alternatively, the locking hole 2821 may, for example, engage with the item in both the first and second directions mentioned above.

[0056] Optionally, in order to adapt to the shape of the item, the card slot 2821 includes a connected flared portion and an arc-shaped portion, and when the second card 200 is in a folded state, the flared portion is positioned towards the first cover plate 210.

[0057] Furthermore, the second limiting plate 282, for example, engages with the item in the depth direction of the locking hole 2821, the depth direction of which is perpendicular to both the first and second directions. This further restricts the movement of the item, thereby improving its stability.

[0058] Optionally, when the second paper card 200 is in a folded state, the second limiting plate 282 contacts the first cover plate 210 to improve the stability of the first limiting plate 281.

[0059] In other embodiments, the second paper card 200 may also exclude the first limiting plate 281 and the second limiting plate 282.

[0060] In another embodiment, the second paper card 200 further includes a first limiting plate 281, which is connected to the first edge 2311 of the through hole 231. When the second paper card 200 is in a folded state, the first limiting plate 281 is located inside the through hole 231 and is coplanar with the second cover plate 230.

[0061] The second paper card 200 also includes a third limiting plate 283, which is foldably connected to the side of the first limiting plate 281 away from the first edge 2311. When the second paper card 200 is in a folded state, the third limiting plate 283 is located on the side of the first limiting plate 281 facing the first cover plate 210 and is perpendicular to the first limiting plate 281. The third limiting plate 283 is used to limit the engagement with the item in a third direction. The third direction is perpendicular to both the first and second directions and is the same as the depth direction of the card hole 2821 mentioned above.

[0062] In this embodiment, the third limiting plate 283 cooperates with the item in the third-party upward direction, thereby restricting the movement of the item in the third-party upward direction and improving the stability of the item.

[0063] Optionally, when the second paper card 200 is in a folded state, the third limiting plate 283 contacts the first cover plate 210 to improve the stability of the first limiting plate 281.

[0064] In other embodiments, the second paper card 200 may also exclude the first limiting plate 281 and the third limiting plate 283.

[0065] In one optional embodiment, the second card 200 includes both a second limiting plate 282 and a third limiting plate 283. In this case, the second limiting plate 282 and the third limiting plate 283 simultaneously engage with the same component of the article in a third-order direction to maintain the stability of the corresponding component of the article. Alternatively, the second limiting plate 282 and the third limiting plate 283 may also engage with different components of the article to restrict the movement of two different components in a third-order direction. In this way, when the second card 200 is in a folded state, the distance between the second limiting plate 282 and the first edge 2311 of the through hole 231 is, for example, smaller than the distance between the third limiting plate 283 and the first edge 2311 of the through hole 231, to meet the limiting requirements of components of different sizes of the article.

[0066] Further, refer to Figure 5 As shown, the buffer structure 400 formed by folding the second paper card 200 includes an inner liner 500. That is, the packaging box provided in this embodiment also includes an inner liner 500. Specifically, the inner liner 500 is located between the first cover plate 210 and the second cover plate 230, and is arranged circumferentially along the through hole 231. The inner liner 500 is, for example, an annular structure. The second limiting plate 282, the third limiting plate 283, and the item are all located in the inner cavity of the inner liner 500. The item includes a first component and a second component that are independent of each other. A part of the first component extends into the space between the first limiting plate 281 and the first cover plate 210 through a snap hole 2821, and the first component is engaged with the snap hole 2821. A receiving space 410 is formed between the third limiting plate 283 and the inner liner 500, and the receiving space 410 is located on the side of the third limiting plate 283 away from the first limiting plate 281. The second component is snapped into the receiving space 410. The first component is, for example, a camera, and the second component is, for example, an accessory box.

[0067] Furthermore, the first abutment plate 271, the second abutment plate 272, the third abutment plate 273, the fourth abutment plate 274, the fifth abutment plate 275, and the sixth abutment plate 276 mentioned above are all located on the outside of the inner liner 500 to prevent these parts from affecting the fixation of the item.

[0068] In another embodiment, reference Figure 2 and Figure 5 As shown, the slot 2821 penetrates the side of the second limiting plate 282 away from the first limiting plate 281 and forms an inlet / outlet 2822. During the switching between the folded and flattened states of the second limiting plate 282, the inlet / outlet 2822 is used to allow items to enter and exit the slot 2821.

[0069] Using the solution in this embodiment, due to the presence of the inlet / outlet 2822, the item can be placed inside the buffer structure 400 first, and then the second limiting plate 282 can be switched from a flattened state to a folded state to secure the item. Conversely, through the inlet / outlet 2822, the second limiting plate 282 can be switched from a folded state to a flattened state beforehand, and then the item can be removed. This method of item placement and removal is relatively convenient and reduces the difficulty of assembling and disassembling the item from the buffer structure 400.

[0070] Furthermore, the first limiting plate 281 is foldably connected to the first edge 2311 of the through hole 231, so that the position of the first limiting plate 281 relative to the through hole 231 is variable. With this configuration, when an item needs to be removed, the second limiting plate 282 can be switched from a folded state to a flattened state first, then the first limiting plate 281 can be folded, changing the positions of both the first and second limiting plates 281 and 282, causing both to move out of the buffer structure 400. The item can then be removed through the through hole 231. In this method of item removal, the first and second limiting plates 281 and 282 are pre-moved out of the buffer structure 400 before the item is removed, thus reducing the difficulty of removing the item.

[0071] In other embodiments, the locator 2821 may not penetrate the side of the second limiting plate 282 away from the first limiting plate 281. In this case, the locator 2821 may have a closed peripheral sidewall, for example.

[0072] In another embodiment, reference Figure 2 and Figure 6 As shown, the second paper card 200 also includes a connecting plate 290. The connecting plate 290 is foldably connected to the side of the first cover plate 210 away from the first side plate 220. The connecting plate 290 is provided with a first mating hole 291 on the side of the first cover plate 210. The side of the second side plate 240 away from the second cover plate 230 is connected to a first locking plate 232. When the second paper card 200 is in a folded state, the connecting plate 290 is stacked on the side of the second side plate 240 facing the first side plate 220, and the first locking plate 232 is engaged in the first mating hole 291.

[0073] In this embodiment, the first cover plate 210 engages with the first locking plate 232 through the first mating hole 291 on the connecting plate 290, thereby achieving the engagement between the first cover plate 210 and the second side plate 240. In this configuration, the engagement between the first cover plate 210 and the second side plate 240 will not damage the integrity of the first cover plate 210, thus ensuring the strength of the first cover plate 210 and giving the first cover plate 210 a better dustproof effect.

[0074] In other embodiments, the second paper card 200 may also exclude the connecting plate 290, in which case the first cover plate 210 is, for example, bonded to the second side plate 240.

[0075] In one specific implementation, both the first paper card 100 and the second paper card 200 are integrally formed from corrugated cardboard, and it should be noted that... Figure 1 and Figure 2 The dashed lines all indicate crease lines. Figure 1 The first paper card 100 is folded along the dotted lines to obtain the box body 300 of the packaging box. Figure 2 The second paper card 200 is folded along the dotted lines to obtain the cushioning structure 400 of the packaging box.

[0076] This application embodiment also provides a packaging box, including a box body 300 and a cushioning structure 400, wherein the cushioning structure 400 is disposed within the box body 300, wherein: The box body 300 is formed by folding the first paper card 100 of the packaging structure described above. The peripheral side wall of the box body 300 is provided with a through hole 1121, which is used to take out and put in the cable of the item inside the box body 300. And / or, the cushioning structure 400 is formed by folding the second paper card 200 of the packaging structure described above. That is, it is possible that only the box body 300 is formed by folding the first paper card 100 or the cushioning structure 400 is formed by folding the second paper card 200, or it is possible that the box body 300 is formed by folding the first paper card 100 while the cushioning structure 400 is formed by folding the second paper card 200.

[0077] The packaging box provided in this embodiment has the same beneficial effects as the packaging structure described above, and will not be repeated here.

[0078] In another embodiment, a sticker is adhered to the outer surface of the box 300, and the sticker covers the through hole 1121. The presence of the sticker prevents external impurities from entering the box 300, thereby improving the sealing performance of the box 300.

[0079] Furthermore, the sticker is, for example, a disposable sticker. In its initial state, the disposable sticker is completely attached to the outer surface of the box 300. Subsequently, as long as the user opens the through hole 1121, the integrity of the disposable sticker will be destroyed. In this way, the integrity of the disposable sticker can be used to determine whether the user has opened the through hole 1121.

[0080] In other embodiments, the outer surface of the box 300 may not have a sticker.

[0081] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
