Description

Technical Field

[0001] This application relates to the field of packaging technology, and more particularly to a packaging box. Background Technology

[0002] With the booming development of e-commerce and the rapid increase in logistics volume, the demand for logistics packaging is also growing. Logistics boxes, as important tools for protecting goods and facilitating transportation and storage, have been widely used. To meet the needs of different goods and logistics, the market currently offers a wide variety of paper logistics boxes, including straight cardboard boxes, corrugated boxes, flap-type boxes, and drawer-type boxes. However, in actual use, the existing logistics boxes have poor structural strength and resistance to external impacts and pressures. Especially for heavy goods, the outer packaging of the logistics boxes is easily deformed or even damaged, making it difficult to guarantee the quality and safety of the products inside.

[0003] To address this issue, additional shock-absorbing materials such as foam plastic, bubble wrap, cardboard dividers, air cushion bags, and silicone pads can be added inside the shipping boxes to increase product protection. However, this also increases the overall weight and volume of the packaging, raising transportation costs. Furthermore, most of these fillers are disposable, which does not align with the current environmentally friendly development philosophy and could exacerbate resource consumption and environmental pollution.

[0004] Therefore, there is an urgent need for a packaging box that can meet basic loading requirements, while also being cost-effective, environmentally friendly, and protecting the product's safety during transportation. Utility Model Content

[0056] In the description and claims of this application and the foregoing drawings, when an element is referred to as "fixed to," "mounted to," "set on," or "connected to" another element, it may be directly or indirectly located on that other element. For example, when an element is referred to as "connected to" another element, it may be directly or indirectly connected to that other element.

[0057] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0058] This application provides a packaging box 100, which is applicable to logistics packaging scenarios. Of course, it can also be applied to other suitable scenarios, which are not particularly limited here.

[0059] like Figures 1 to 4 As shown, the packaging box 100 has a first state and a second state, wherein the second state is formed by at least partially unfolding the first state. It should be noted that the first state can be the packaged state of the packaging box 100, and the second state can be the state in which the packaging box 100 is fully or partially unfolded.

[0060] In the first state, that is, in the packaging state of box 100, such as Figure 1As shown, the packaging box 100 includes a box bottom 1 and a box body 2. The box body 2 is formed on the box bottom 1 and has a receiving cavity 25 formed by a surrounding panel. Understandably, at least one surrounding panel may be provided, as long as it can form a receiving cavity 25 for accommodating the target object. That is, the box body 2 may be a multi-sided box, a single-sided box such as a circular box, or of course, other suitable shapes of box body 2, which are not particularly limited here.

[0061] Specifically, in the embodiments of this application, such as Figure 1 As shown, the enclosure includes a first enclosure 21, a second enclosure 22, a third enclosure 23, and a fourth enclosure 24 connected by a locking structure and / or a plug-in structure, wherein each enclosure forming the receiving cavity 25 has a buffer cavity 26. Understandably, the first enclosure 21, the second enclosure 22, the third enclosure 23, and the fourth enclosure 24 can form a four-sided box 2, and each of the first enclosure 21, the second enclosure 22, the third enclosure 23, and the fourth enclosure 24 has a buffer cavity 26.

[0062] For example, when the first enclosure 21, the second enclosure 22, the third enclosure 23, and the fourth enclosure 24 together form a four-sided box 2, the first enclosure 21, the second enclosure 22, the third enclosure 23, and the fourth enclosure 24 can be connected to each other by a locking structure, a plug-in structure, or a combination of locking and plug-in structures. For example, the first enclosure 21 and the second enclosure 22 are connected by a locking structure, the third enclosure 23 is connected to the first enclosure 21 and the second enclosure 22 by a plug-in structure, and the fourth enclosure 24 is also connected to the first enclosure 21 and the second enclosure 22 by a plug-in structure, thereby strengthening the structural strength and stability of the box 2 in the first state.

[0063] It should be noted that the enclosure panels described in this article generally have a certain thickness and multiple wall surfaces. When a wall surface of a certain enclosure panel is compressed, all the wall surfaces of that enclosure panel can disperse the compression deformation, which obviously helps to improve the structural strength of the box body 2.

[0064] According to the embodiments of this application, the packaging box 100 has at least the following beneficial effects:

[0065] On the one hand, by designing each side of the box body 2 as a surrounding structure, the packaging box 100 can enhance the structural strength of the box body 2. Through the buffer cavities 26 that form the surrounding panels of the box body 2, the shockproof and drop-proof buffering capacity of the packaging box 100 can be effectively increased. Furthermore, by using the walls of each surrounding panel, the external extrusion pressure is dispersed, so that the extrusion pressure on the target object carried in the receiving cavity 25 is a dispersed extrusion pressure, ensuring that it is not prone to local extrusion deformation, and thus reducing the probability of damage to the target object during transportation.

[0066] On the other hand, the packaging box 100 does not require internal fillers, which ensures that production and transportation costs are reduced without increasing the overall weight and volume of the packaging box 100, as well as reducing the likelihood of resource consumption and environmental pollution, in line with the concept of sustainable development.

[0067] To enable those skilled in the art to better understand the present application, the following will be discussed in conjunction with the appendix. Figures 1 to 7 The technical solutions in the embodiments of this application will be clearly and completely described.

[0068] In some embodiments of this application, to enhance the structural strength of the enclosure and provide stronger support, the enclosure is a multi-layered structure and is formed by folding at least a portion of the packaging box 100 in the second state.

[0069] It should be noted that since the first state of the packaging box 100 is the unfolded state, and the second state is the fully or partially unfolded state, for ease of explanation, the first and second states of the packaging box 100 can actually be separated onto each of the side panels or the box body 2 or the box lid 28 described below. That is, the box body 2 has its own first and second states, and similarly, the side panels also have their own first and second states.

[0070] Understandably, when the panels forming the box body 2 are in the first state, the box body 2 is in the first state; when the box body 2 is in the first state, the packaging box 100 is in a first state (see...). Figure 1 When both box body 2 and the lid 28 described below are in the first state, the packaging box 100 is in another first state (not shown in the figure). For ease of explanation, this article mainly refers to... Figure 1 The state of the middle packaging box 100 is described as the first state of the packaging box 100.

[0071] For example, the packaging box 100 in the second state described herein can be decomposed into a box body 2 in the second state. Since the box body 2 of the packaging box 100 generally needs to be folded multiple times, the box body 2 in the second state has various structural forms.

[0072] For example, Figure 1 The third enclosure 23 can be made of Figure 2 The corresponding unfolded cardboard, after being folded, forms Figure 5 The structure is further folded to form the third enclosure 23 in the second state. That is, the third enclosure 23 in the second state includes, but is not limited to, [the following structures are also included in the original text]. Figure 2 The fully unfolded state structure Figure 5 The structure is in a partially folded state. Of course, other suitable posture structures are also possible, and no particular limitation is made here, as long as the third enclosure 23 structure in the first state can be formed.

[0073] Also exemplarily, specifically in this embodiment, in order to simplify the overall structure and facilitate production and assembly, the first enclosure 21, the second enclosure 22, the third enclosure 23 and the fourth enclosure 24 are all two-layer structures. Of course, in other embodiments, there may be more layers, which is not particularly limited here, as long as each enclosure has sufficient structural strength.

[0074] In some embodiments of this application, such as Figure 2 As shown, the box body 2 includes a sub-box body 27, which is formed by the first enclosure 21 and the second enclosure 22 being arranged opposite to each other. It should be noted that, in order to facilitate assembly into the box body 2, the sub-box body 27 can be pre-formed before the third enclosure 23 and the fourth enclosure 24 are formed.

[0075] like Figure 1 As shown, the third enclosure 23 and the fourth enclosure 24 are respectively arranged on opposite sides of the sub-box 27 to form a box 2 with a receiving cavity 25 together with the sub-box 27. Understandably, the first enclosure 21, the second enclosure 22, the third enclosure 23 and the fourth enclosure 24 together form a four-sided box.

[0076] Of course, those skilled in the art will understand that in some embodiments, more enclosure structures can be used to form tetrahedrons, pentahedrons, hexahedrons, etc.

[0077] For example, the first enclosure 21 and the second enclosure 22 are arranged opposite each other front to back, and the third enclosure 23 and the fourth enclosure 24 are arranged opposite each other left to right. In terms of size, the first enclosure 21 and the second enclosure 22 are the same, the third enclosure 23 and the fourth enclosure 24 are the same, and the length of the first enclosure 21 is greater than the length of the third enclosure 23, so that the first enclosure 21, the third enclosure 23, the second enclosure 22 and the fourth enclosure 24 are connected in sequence to form a rectangular box with a receiving cavity 25.

[0078] Of course, those skilled in the art will understand that in some embodiments, the four panels may be of equal length, thereby forming a square box together.

[0079] In some embodiments of this application, to improve the shockproof and drop-proof cushioning capability of the packaging box 100, in the second state, specifically the second state of the box body 2 or the second state of the packaging box 100, before the sub-box body 27 is formed on the box bottom 1, the first surrounding plate 21 and the second surrounding plate 22 are connected through the sub-box bottom 271 and located on the first side of the box bottom 1. For example... Figure 1 and Figure 2As shown, in the first state, the first enclosure 21 and the second enclosure 22 are folded and placed around the bottom 271 of the sub-box to form the sub-box body 27. In this way, by ensuring that the first enclosure 21 and the second enclosure 22 can be connected through the bottom 271 of the sub-box after folding, on the one hand, when the first enclosure 21 (or the second enclosure 22) is subjected to an impact force, the impact force can be dispersed to the second enclosure 22 (or the first enclosure 21) through the bottom 271 of the sub-box, so as to disperse the impact force to the entire sub-box body 27, which is conducive to effectively dispersing the impact force and reducing the probability that the top side of the packaging box 100 will deform, fall apart or break due to pressure.

[0080] On the other hand, when a long side of the first enclosure 21 (or the second enclosure 22) is subjected to an impact force, the impact force can be transmitted and dispersed to the other long sides of the first enclosure 21, and also transmitted to the second enclosure 22 through the sub-box bottom 271. When the third enclosure 23 and the fourth enclosure 24 are connected to the sub-box body 27, the impact force can also be distributed to the entire box body 2, which helps to further disperse the impact force and reduce the probability of the packaging box 100 being deformed, scattered or broken.

[0081] In some embodiments of this application, in a first state, for example, in the first state of sub-box 27, such as... Figure 2 and Figure 3 As shown, in order to improve the structural strength of the sub-box 27 and prevent the sub-box 27 from falling apart and affecting the structural stability and reliability of the box 2, the same side ends of the first enclosure 21 and the second enclosure 22 are connected by a locking structure.

[0082] Of course, in other embodiments, the first enclosure 21 can be connected to the third enclosure 23 (or the fourth enclosure 24) via a plug-in structure, and one end of the second enclosure 22 can be connected to the third enclosure 23 (or the fourth enclosure 24) via a plug-in structure, so as to enhance the connection stability and reliability between the first enclosure 21 and the second enclosure 22 in the sub-box 27. Alternatively, the first enclosure 21 and the second enclosure 22 can also be connected by other existing or newly created structures, which will not be described in detail here.

[0083] Exemplarily, specifically in some embodiments, such as Figure 2 and Figure 3 As shown, the locking structure includes a first locking tongue 2114 and a second locking tongue 2214. The first locking tongue 2114 is formed in the first enclosure 21, and correspondingly, the second locking tongue 2214 is formed in the second enclosure 22. When the first enclosure 21 and the second enclosure 22 are arranged opposite to each other, the second locking tongue 2214 is cross-connected with the first locking tongue 2114 to ensure that the first enclosure 21 and the second enclosure 22 are stably connected. The impact force received by the first enclosure 21 and / or the second enclosure 22 is dispersed and transmitted to the side through the cross-connection of the first locking tongue 2114 and the second locking tongue 2214, thus achieving an adaptive buffering effect.

[0084] In some embodiments of this application, such as Figure 4 As shown, to facilitate the formation of the first enclosure 21 and reduce production costs, the first enclosure 21 includes a first side panel 211, which is folded to form the first enclosure 21. Specifically, the first side panel 211 includes a first inner panel 2111, a first connecting plate 2112, and a first outer panel 2113 connected sequentially by fold lines. The first inner panel 2111 and the first outer panel 2113 are folded along the fold lines to form the first enclosure 21 together with the first connecting plate 2112 (see [reference]). Figures 1 to 3 ).

[0085] Understandably, in the first state, the first inner plate 2111 of the first enclosure 21 faces the receiving cavity 25, the first outer plate 2113 faces away from the receiving cavity 25, and the first connecting plate 2112 is the top of the first enclosure 21. The first inner plate 2111 and the first outer plate 2113, which are folded relative to each other and spaced apart, together with the first connecting plate 2112, can also form a buffer cavity 26 of the first enclosure 21.

[0086] Similarly, to facilitate the formation of the second enclosure 22 and reduce production costs, such as Figure 4 As shown, the second enclosure 22 includes a second side panel 221, which is folded to form the second enclosure 22. Specifically, the second side panel 221 includes a second inner panel 2211, a second connecting plate 2212, and a second outer panel 2213 connected sequentially by fold lines. The second inner panel 2211 and the second outer panel 2213 are folded along the fold lines to form the second enclosure 22 together with the second connecting plate 2212 (see [reference]). Figures 1 to 3 ).

[0087] Understandably, in the first state, the second inner plate 2211 of the second enclosure 22 faces the receiving cavity 25 and is opposite to the first inner plate 2111. The second outer plate 2213 is away from the receiving cavity 25, and the second connecting plate 2212 is the top of the second enclosure 22. The second inner plate 2211 and the second outer plate 2213, which are folded relative to each other and spaced apart, together with the second connecting plate 2212, can also form a buffer cavity 26 of the second enclosure 22.

[0088] In addition, such as Figures 2 to 4 As shown, to form the above-mentioned locking structure, the first side plate 211 further includes a first locking tongue 2114, and the second side plate 221 further includes a second locking tongue 2214. The opposite ends of the first inner plate 2111 are connected to the first locking tongue 2114 through fold lines, and the opposite ends of the second inner plate 2211 are connected to the second locking tongue 2214 through fold lines. After the sub-box 27 is formed, the second locking tongue 2214 and the first locking tongue 2114 can be connected in a cross-shaped manner to ensure the structural stability of the sub-box 27 and improve the self-buffering capability of the sub-box 27.

[0089] For example Figure 4 As shown, the bottom 271 of the sub-box body 27 is connected between the first inner plate 2111 and the second inner plate 2211 via fold lines. The first side plate 211, the second side plate 221, and the bottom 271 together form the sub-box body 27. Understandably, the aforementioned sub-box body 27 can be formed by folding the first side plate 211, the second side plate 221, and the bottom 271.

[0090] It should be noted that, for example, Figure 4 As shown, the box bottom 1 includes a sub-box bottom 271 and a box bottom plate 11. The box bottom plate 11 has a first side and a second side, wherein the first side plate 211, the second side plate 221 and the sub-box bottom 271 are all located on the first side of the box bottom plate 11, so as to realize that the first side plate 21 and the second side plate 22 are located on the first side of the box bottom 1.

[0091] In some embodiments of this application, such as Figure 4 As shown, to facilitate the formation of the third enclosure 23 and reduce production costs, the third enclosure 23 includes a third side panel 231, which is folded to form the third enclosure 23. Specifically, the third side panel 231 includes a third inner panel 2311, a third connecting plate 2312, and a third outer panel 2313 connected sequentially by fold lines. After the sub-box body 27 is formed on the box bottom 1, the third inner panel 2311 and the third outer panel 2313 are folded along the fold lines to form the third enclosure 23 together with the third connecting plate 2312 (see...). Figure 1 and Figure 5 ).

[0092] Understandably, in the first state, the third inner plate 2311 of the third enclosure 23 faces the receiving cavity 25, the third outer plate 2313 faces away from the receiving cavity 25, and the third connecting plate 2312 is the top of the third enclosure 23. The third inner plate 2311 and the third outer plate 2313, which are folded relative to each other and spaced apart, together with the third connecting plate 2312, can also form the buffer cavity 26 of the third enclosure 23.

[0093] Correspondingly, to facilitate the formation of the fourth enclosure panel 24 and reduce production costs, such as Figure 4 As shown, the fourth enclosure 24 includes a fourth side panel 241, which is folded to form the fourth enclosure 24. Specifically, the fourth side panel 241 includes a fourth inner panel 2411, a fourth connecting plate 2412, and a fourth outer panel 2413 connected sequentially by fold lines. After the sub-box body 27 is formed on the box bottom 1, the fourth inner panel 2411 and the fourth outer panel 2413 are folded along the fold lines to form the fourth enclosure 24 together with the fourth connecting plate 2412 (see...). Figure 1 and Figure 5 ).

[0094] Understandably, in the first state, the fourth inner plate 2411 of the fourth enclosure 24 faces the receiving cavity 25 and is opposite to the third inner plate 2311. The fourth outer plate 2413 is away from the receiving cavity 25, and the fourth connecting plate 2412 is the top of the fourth enclosure 24. The fourth inner plate 2411 and the fourth outer plate 2413, which are folded relative to each other and spaced apart, together with the fourth connecting plate 2412, can also form a buffer cavity 26 of the fourth enclosure 24.

[0095] For example, specifically in this embodiment, in the first state, the sub-box bottom 271 of the sub-box body 27 and the box bottom plate 11 of the box bottom 1 are stacked one on top of the other to form a double-layered box bottom 1. Furthermore, the first inner plate 2111 of the first surrounding plate 21, the third inner plate 2311 of the third surrounding plate 23, the second inner plate 2211 of the second surrounding plate 22, the fourth inner plate 2411 of the fourth surrounding plate 24, and the sub-box bottom 271 of the sub-box body 27 together form the aforementioned receiving cavity 25.

[0096] In addition, to further improve the structural strength and cushioning capacity of the box body 2, in the first state, the buffer cavity 26 of the third enclosure 23 is provided with a locking tongue structure on one side of the first enclosure 21 and the second enclosure 22. Correspondingly, the buffer cavity 26 of the fourth enclosure 24 is provided with a locking tongue structure on the other side of the first enclosure 21 and the second enclosure 22.

[0097] Understandably, on the one hand, since the second locking tongue 2214 and the first locking tongue 2114 in the above-mentioned locking structure can only be separated from the height direction of the box body 2, the locking structures at the opposite ends of the first enclosure 21 and the second enclosure 22 are respectively placed in the buffer cavities 26 of the third enclosure 23 and the fourth enclosure 24. The third enclosure 23 and the fourth enclosure 24 can constrain the corresponding locking structures in the height direction to reduce the probability of the locking structure coming apart, thereby ensuring that the locking structure is stably used to disperse the impact force on the first enclosure 21 and / or the second enclosure 22.

[0098] On the other hand, when the third enclosure 23 (or the fourth enclosure 24) is subjected to impact force, the corresponding locking structure in the buffer cavity 26 of the third enclosure 23 (or the fourth enclosure 24) can also increase the impact resistance of the third enclosure 23 (or the fourth enclosure 24). That is, the locking structure in the third enclosure 23 (or the fourth enclosure 24) can further play an internal self-buffering role.

[0099] In some embodiments of this application, such as Figure 4 As shown, to improve the structural strength and stability of the box 2, the third side panel 231 also includes a third fixing plate 2314. The third fixing plate 2314 is connected to the third inner panel 2311 and the side facing away from the third connecting plate 2312 via a fold line. During the formation of the third enclosure panel 23 (see...), Figure 5The third fixing plate 2314 is folded along its crease line and inserted between the third inner plate 2311 and the bottom of the box 1 to lock the third enclosure plate 23.

[0100] For example, in the first state of the box body 2, the third inner plate 2311 and the fourth inner plate 2411 are arranged opposite to each other, and the third fixing plate 2314 is inserted between the third inner plate 2311 and the sub-box bottom 271. On the one hand, the third inner plate 2311 can serve as an internal support for the box body 2, which is beneficial to improving the structural strength of the box body 2; on the other hand, the third enclosure plate 23 can be self-locking, which is beneficial to improving the stability of the box body 2 structure and making it less likely to fall apart.

[0101] And / or, in some embodiments of this application, such as Figure 4 As shown, to improve the structural strength and stability of the box body 2, the fourth side panel 241 also includes a fourth fixing plate 2414. The fourth fixing plate 2414 is connected to the fourth inner panel 2411 and the side opposite to the fourth connecting plate 2412 via a fold line. During the formation of the fourth enclosure panel 24, the fourth fixing plate 2414 is folded along its fold line and inserted between the fourth inner panel 2411 and the box bottom 1 to lock the fourth enclosure panel 24.

[0102] For example, in the first state of the box body 2, the third inner plate 2311 and the fourth inner plate 2411 are arranged opposite to each other, and the fourth fixing plate 2414 is inserted between the fourth inner plate 2411 and the bottom of the sub-box 271. On the one hand, the fourth inner plate 2411 can serve as another internal support for the box body 2, which is beneficial to improving the structural strength of the box body 2; on the other hand, it can realize the self-locking of the fourth enclosure plate 24, which is beneficial to improving the stability of the structure of the box body 2 and preventing it from easily falling apart.

[0103] In some embodiments of this application, to facilitate the assembly and disassembly of the packaging box 100 and make the packaging box 100 reusable, after the box body 2 is formed, that is, in the first state of the box body 2, a first handle 23111 is provided on the side of the third inner plate 2311 facing the receiving cavity 25. Correspondingly, a second handle 24111 is provided on the side of the fourth inner plate 2411 facing the receiving cavity 25 (see...). Figure 1 ).

[0104] It should be noted that both the first buckle handle 23111 and the second buckle handle 24111 are, but are not limited to, through holes, protrusions, etc. For example, as shown... Figure 2 and Figure 4 As shown, a through hole can be made on the third inner plate 2311 of the third side plate 231. After the third enclosure 23 is formed, the through hole of the third inner plate 2311 faces the receiving cavity 25 and communicates with the receiving cavity 25. In this way, the user can directly insert his finger into the through hole to pull open the third side plate 231 so that the third side plate 231 gradually unfolds.

[0105] Similarly, a through hole can be made on the fourth inner plate 2411 of the fourth side plate 241. After the fourth enclosure plate 24 is formed, the through hole of the fourth inner plate 2411 faces the receiving cavity 25 and communicates with the receiving cavity 25. In this way, the user can directly insert his finger into the through hole to pull open the fourth side plate 241 so that the fourth side plate 241 gradually unfolds.

[0106] It should be noted that, specifically in this embodiment, to further improve the structural strength and stability of the box 2, adjacent side panels are connected by a plug-in structure. The plug-in structure includes a tongue and a hole, with the tongue formed in one of the adjacent side panels and the hole formed in the other.

[0107] For example, to facilitate disassembly and assembly and simplify the overall structure, first insertion holes 2115 are formed at opposite ends of the first outer plate 2113 forming the first side plate 211 of the first enclosure 21 (see...). Figure 4 ) and second socket 2116 (see Figure 2 Similarly, third insertion holes 2215 are formed at opposite ends of the second outer plate 221 forming the second side plate 221 of the second enclosure 22 (see...). Figure 4 ) and fourth socket 2216 (see Figure 2 Correspondingly, first tongues 2315 protrude from opposite sides of the third outer plate 2313 forming the third enclosure 23 (see...). Figure 2 and Figure 4 ) and second tongue 2316 (see Figure 4 The fourth outer plate 2413 forming the fourth enclosure 24 has third tongues 2415 protruding on opposite sides (see...). Figure 2 and Figure 4 ) and fourth tongue 2416 (see Figure 2 and Figure 4 ).

[0108] During the formation of the third enclosure 23 after the sub-box 27 is formed, the first tongue 2315 of the third outer plate 2313 can be inserted into the first hole 2115 of the first outer plate 2113. Correspondingly, the second tongue 2316 of the third outer plate 2313 can be inserted into the third hole 2215 of the second outer plate 2213, so as to connect the third enclosure 23 to one side of the first enclosure 21 and the second enclosure 22. Similarly, during the formation of the fourth enclosure 24 after the sub-box 27 is formed, the third tongue 2415 of the fourth outer plate 2413 can be inserted into the second hole 2116 of the first outer plate 2113. Correspondingly, the fourth tongue 2416 of the fourth outer plate 2413 can be inserted into the fourth hole 2216 of the second outer plate 2213, so as to connect the fourth enclosure 24 to the other side of the first enclosure 21 and the second enclosure 22.

[0109] In some embodiments of this application, the packaging box 100 is a single-piece structure, wherein the bottom 1 and the body 2 are formed by folding a single piece of cardboard. This can greatly reduce the use of raw materials and simplify the manufacturing process, thereby reducing production costs and pollution caused by manufacturing.

[0110] In some embodiments of this application, to achieve packaging of the packaging box 100 and simplify the assembly and disassembly of the packaging box 100, the packaging box 100 further includes a lid 28 (see...). Figures 1 to 5 The lid 28 is located on the second side of the bottom 1 of the box. After being bent from the second side of the bottom 1 of the box to the first side of the bottom 1 of the box, the lid 28 closes onto the box body 2 to seal the receiving cavity 25 and cover the sub-box body 27.

[0111] In some embodiments of this application, to further facilitate the assembly and disassembly of the packaging box 100 and reduce production costs, the box lid 28 is formed by folding a single sheet of cardboard. Specifically, as shown... Figure 4 As shown, the box lid 28 includes a front cover plate 281, a top cover plate 282, and a rear cover plate 283 connected sequentially by fold lines. After the box body 2 is formed on the box bottom 1, the front cover plate 281 and the rear cover plate 283 are folded along the fold lines to respectively wrap around the outer walls of the second enclosure 22 and the first enclosure 21, and to close the top cover plate 282 onto the box body 2 to seal the receiving cavity 25. It should be noted that, as... Figure 4 As shown, the rear cover 283 is connected to the second side of the bottom plate 11 of the box bottom 1 via a fold line, and the first side plate 211 is connected to the first side of the bottom plate 11 of the box bottom 1 via a fold line. Understandably, after the box body 2 is formed, the lid 28 is located on the first side of the box body 2.

[0112] For example, in the first state, the front cover 281 of the box cover 28 can be attached to the first outer plate 2113 of the first enclosure 21, the rear cover 283 can be attached to the second outer plate 2213 of the second enclosure 22, and the top cover 282 can be attached to the first connecting plate 2112, the second connecting plate 2212, the third connecting plate 2312, and the fourth connecting plate 2412 at the corresponding position of the receiving cavity 25 to seal the receiving cavity 25. Understandably, the area of ​​the top cover 282 is larger than the opening area of ​​the receiving cavity 25.

[0113] And / or, in some embodiments of this application, to ensure that the lid 28 securely seals the receiving cavity 25, the lid 28 and the sub-box 27 are connected by a plug-in structure and / or a magnetic structure.

[0114] For example, specifically in this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the top cover plate 282 of the box cover 28 has a fifth tongue 284 and a sixth tongue 285 protruding from opposite ends. Correspondingly, as shown in the figure... Figure 1 , Figure 2 and Figure 4 As shown, a fifth insertion hole 2317 is formed on the third side panel 23, and a sixth insertion hole 2417 is formed on the fourth side panel 24. For example, a fifth insertion hole 2317 is formed between the third outer panel 2313 and the third connecting plate 2312 in the third side panel 231, and a fifth insertion hole 2317 is formed between the fourth outer panel 2413 and the fourth connecting plate 2412 in the fourth side panel 241. After the box body 2 is formed, during the folding and closing of the box lid 28, the fifth insertion tongue 284 can be inserted into the fifth insertion hole 2317 of the third side panel 23, and the sixth insertion tongue 285 can be inserted into the sixth insertion hole 2417 of the fourth side panel 24, so as to achieve a firm connection between the box lid 28 and the sub-box body 27.

[0115] In other embodiments, the magnetic structure may include a first magnetic element and a second magnetic element. The first magnetic element may be disposed on the first outer plate 2113 of the first side plate 211, and the second magnetic element may be disposed on the front cover plate 281 of the cover 28. When the cover 28 is closed on the sub-box body 27, a firm connection between the cover 28 and the sub-box body 27 can be achieved by the magnetic attraction between the first magnetic element and the second magnetic element.

[0116] Of course, in other embodiments, the lid 28 and the body 2 can also be securely connected by other existing or new structures, which will not be elaborated here.

[0117] In some embodiments of this application, the packaging box 100 is a single-piece structure, wherein the box bottom 1, box body 2 and box lid 28 are formed by folding a single piece of cardboard. This can greatly reduce the use of raw materials and simplify the manufacturing process, thereby reducing production costs and pollution caused by manufacturing.

[0118] It should be noted that, specifically in this embodiment, for the convenience of packaging the target object's accessories through the packaging box 100, such as... Figure 6 and Figure 7 The packaging box 100 also includes an inner liner 3, which has a recessed groove 31 for accommodating auxiliary components. When the inner liner 3 is placed within the receiving cavity 25 of the box body 2, the receiving cavity 25 forms a main cavity and an auxiliary cavity formed by the groove 31. Exemplarily, the space within the receiving cavity 25, excluding the space occupied by the inner liner 3, constitutes the main cavity, which is primarily used to accommodate the target object. The auxiliary cavity formed by the groove 31 is used to accommodate auxiliary components. For example, after accommodating the auxiliary component in the groove 31, the target object can then be placed in the main cavity. Alternatively, if the inner liner 3 is removed, the target object can be directly placed in the receiving cavity 25. In practical applications, the specific method can be determined according to the user's actual needs, and no particular limitation is made here.

[0119] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
