[0038] The following is combined Figures 1 to 7 This describes the packaging box of an embodiment of the present utility model.

[0039] According to an embodiment of the present invention, a packaging box is provided, comprising a box body 1 and a pair of limiting inner liners 2. Specifically, as Figure 1 As shown, the box 1 is a one-piece folding structure, and it can switch between an unfolded and folded state. Generally, the box 1 is designed as a cuboid structure. Specifically, as... Figure 1As shown, the housing 1 includes a bottom plate 101, a pair of first side plates 102, and a pair of second side plates 103. The bottom plate 101 has a pair of first side edges 1011 extending along a first direction X and a pair of second side edges 1012 extending along a second direction Y. The pair of first side plates 102 are respectively connected to the pair of first side edges 1011, and the pair of second side plates 103 are respectively connected to the pair of second side edges 1012. The first direction X intersects the second direction Y; in this embodiment, the first direction X and the second direction Y are perpendicular to each other.

[0040] See Figure 1 As shown, a pair of limiting inner liners 2 are integrally folded and formed with the box body 1, which can reduce the steps and costs in the manufacturing and assembly process. For example, Figure 1 As shown, a pair of limiting inner liners 2 are respectively connected to the side of a pair of first side plates 102 facing away from the bottom plate 101, and the pair of limiting inner liners 2 are respectively provided with limiting holes 201 adapted to the product 4. Both ends of the product 4 are respectively inserted into the pair of limiting holes 201. It can be understood that the shape of the limiting holes 201 should be consistent with the outer contour of the product 4 in order to better fix and protect the product 4. Taking the product 4 as a battery as an example... Figure 7 As shown, the battery has a square structure, then as Figure 1 As shown, the limiting hole 201 is designed to be square; if the battery is a cylindrical battery, the corresponding limiting hole 201 is designed to be circular.

[0041] With this configuration, by folding the box body 1 and the limiting liner 2 together, when the box body 1 is in the folded state, as... Figure 7 As shown, the limiting liner 2 is folded inside the box body 1. The two ends of the product 4 are inserted into the limiting holes 201 on both sides, which can limit and fix the product 4, preventing damage during transportation or storage. This reduces the use of packaging materials such as card cutters and pearl cotton liners, and is easy to operate, improving packaging efficiency and reducing packaging costs. When the box body 1 is in the unfolded state, as... Figure 2 As shown, the packaging box is flat, which facilitates storage and transportation and effectively reduces the space occupied by inventory.

[0042] In some embodiments of this utility model, the limiting liner 2 includes a first folded edge plate 202 and an inner liner plate 203. For example... Figure 1 As shown, the first folded edge plate 202 is connected to the side of the first side plate 102 opposite to the bottom plate 101. The inner lining plate 203 is connected to the side of the first folded edge plate 202 opposite to the first side plate 102, and the inner lining plate 203 is provided with a limit hole 201. When the box body 1 is in the folded state, as... Figure 4As shown, the first side plate 102, the first folded edge plate 202 and the inner lining plate 203 are folded inward along the fold lines at the connection. At this time, due to the presence of the first folded edge plate 202, a certain accommodating space is formed between the first side plate 102 and the inner lining plate 203, and the product 4 can be inserted into the accommodating space through the limiting hole 201.

[0043] With this configuration, the first folded edge plate 202 can form a receiving space between the first side plate 102 and the inner lining plate 203 for the product 4 to extend into, thereby enabling the inner lining plate 203 to more reliably support and fix the product 4, ensuring that the product 4 will not easily come out of the limiting hole 201.

[0044] Preferably, in some embodiments of this utility model, such as Figure 1 As shown, the inner lining plate 203 is provided with multiple limiting holes 201, which are spaced apart along the first direction X. This arrangement ensures that when the housing 1 is in a folded state, as... Figure 7 As shown, multiple products 4 can be limited and fixed, ensuring a certain gap between adjacent products 4 to prevent collisions and fully utilize the internal space of the housing 1. It should be noted that the number and spacing of the limiting holes 201 can be determined according to actual design requirements. Figure 1 As shown in the example, the inner lining plate 203 is provided with three limiting holes 201, and the three limiting holes 201 are evenly distributed along the first direction X.

[0045] Furthermore, in some embodiments of this utility model, the limiting liner 2 further includes a second folded edge plate 204, such as... Figure 1 As shown, the second folded edge plate 204 is connected to the inner lining plate 203 on the side opposite to the first folded edge plate 202. When the box body 1 is in the folded state, as... Figure 3 As shown, the first side plate 102, the first folded edge plate 202, the inner lining plate 203, and the second folded edge plate 204 are folded inward sequentially along the crease at the joint, thus, as... Figure 4 As shown, the first folded edge plate 202 and the second folded edge plate 204 are vertically opposite each other, and the inner lining plate 203 and the first side plate 102 are front-to-back opposite each other, forming a stable support and limiting structure.

[0046] With this configuration, the limiting liner 2 is firmly fixed inside the box 1 through the cooperation of the first folding plate 202 and the second folding plate 204, forming a stable and efficient fixing system. The whole is folded and formed in one piece, which not only simplifies the manufacturing process and reduces costs, but also improves the overall strength and durability of the box 1, and can better protect the product 4 inside the box 1.

[0047] Optionally, in some embodiments of this utility model, when the box 1 is in the unfolded state, such as... Figure 1As shown, the dimension L4 of the second folded edge plate 204 along the second direction Y is less than or equal to the dimension L3 of the first folded edge plate 202 along the second direction Y. With this configuration, since L4 is less than or equal to L3, when the limiting liner 2 is folded inside the box body 1, the width of the lower second folded edge plate 204 does not exceed the width of the upper first folded edge plate 202. This ensures that after folding, the liner plate 203 remains vertical, facilitating the insertion of the product 4 into the limiting hole 201, thereby better limiting and fixing the product 4 and improving packaging convenience.

[0048] In some embodiments of this utility model, such as Figure 1 As shown, the housing 1 also includes a pair of flip covers 104, which are respectively connected to a pair of second side panels 103 on the side opposite to the bottom plate 101. Specifically, as... Figures 2 to 6 The diagram shows the folding process of the packaging box. When folding the packaging, as follows... Figure 3 As shown, first fold the second folded edge plates 204, inner lining plate 203, first folded edge plate 202, and first side plate 102 inward in sequence, so that the limiting inner lining 2 is located inside the box 1 and remains upright. At this time, the product 4 can be inserted into the limiting hole 201. Then, as shown... Figure 4 and Figure 5 As shown, the flip covers 104 on both sides and the second side panel 103 are folded inward in sequence to form the final shape as shown. Figure 6 The enclosed box shown.

[0049] This design allows the entire packaging box to be folded into a single piece, forming a complete box structure. It is easy to operate, facilitates folding and storage, and makes the entire packaging box more flexible and efficient during transportation and storage. It also reduces the number of steps and costs in the manufacturing process and improves the strength and stability of the packaging box.

[0050] Furthermore, in some embodiments of this utility model, such as Figure 1 As shown, the housing 1 also includes a pair of insert plates 105, which are respectively connected to the side of a pair of flip covers 104 facing away from the second side panel 103. The limiting liner 2 and the first side panel 102 are respectively provided with slots 3, so that when the housing 1 is in the folded state, as... Figure 6 As shown, a pair of insert plates 105 are inserted into slot 3.

[0051] Specifically, such as Figure 1 As shown, the first side panel 102, the first folded edge panel 202, and the inner lining panel 203 are respectively provided with interconnecting notches to form slots 3. When the packaging box is in a folded state, as... Figure 5 As shown, slot 3 is located at the top of box 1. Insert the side plates 105 into slot 3 to directly seal the box and fix the folded state of box 1.

[0052] This design, through the cooperation of the side plates 105 and slots 3, ensures that the box 1 remains stable in the folded state, preventing it from being accidentally unfolded. This eliminates the need for sealing tape, making it more convenient and environmentally friendly, and improving the practicality of the packaging box.

[0053] Preferably, in some embodiments of this utility model, when the box 1 is in the unfolded state, such as... Figure 1 As shown, the slot 3 on the first side plate 102 has a dimension of L1 along the second direction Y, and the insertion plate 105 has a dimension of L2 along the first direction X, where L2 is less than or equal to L1. With this configuration, when the packaging box is in a folded state, as... Figure 6 As shown, since L2 is less than or equal to L1, it ensures that the insert plate 105 can be reliably inserted into the slot 3, and keeps the top surface of the box 1 flat. In this way, on the one hand, the stability of the box 1 in the folded state can be guaranteed, preventing accidental unfolding; on the other hand, it also facilitates the stacking of the folded packaging box, making transportation easier and improving the safety and reliability during transportation.

[0054] In an optional embodiment of this utility model, the packaging box is made of cardboard. This design results in low packaging costs and light weight, facilitating handling and transportation, reducing logistics costs. Cardboard is easy to cut and fold, allowing for the design of packaging boxes of various sizes to meet diverse packaging needs. Furthermore, cardboard is a recyclable material; recycling and reuse can reduce resource waste and environmental pollution, aligning with the concept of sustainable development.

[0055] Specifically, in some embodiments of this invention, the cardboard is corrugated cardboard. This configuration, by adding a corrugated structure, enhances its compression and impact resistance, effectively protecting the contents of the box from damage. Furthermore, the wavy structure of the corrugated core paper provides excellent cushioning performance, absorbing and dispersing impact forces, offering additional protection for the contents of the box.

[0056] In summary, the packaging box provided by this utility model is an integral folding packaging, that is, the box body 1 and the limiting inner liner 2 are integrally formed, eliminating the need for additional cushioning structures such as cutters or pearl cotton linings, reducing packaging materials and lowering packaging costs. It can be folded quickly, is easy to use, and unfolds into a flat shape, facilitating storage and transportation while reducing space occupation. Furthermore, after folding, the insert plate 105 engages with the slot 3 to ensure the stability of the folded state, eliminating the need for sealing with tape, making the packaging more environmentally friendly.

[0057] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
