Description
Technical Field
[0001] This utility model belongs to the field of packaging box technology, specifically relating to a fixed inner liner airplane box. Background Technology
[0002] The "airplane box," named for its resemblance to an airplane when unfolded, is a type of cardboard box and a top choice for express delivery packaging and shipping. Made of corrugated cardboard, the airplane box is widely used in various fields due to its unique structure and excellent pressure resistance. It is prevalent in e-commerce logistics, where its sturdy structure and cushioning effectively protect goods during long-distance transportation. Furthermore, its environmentally friendly and recyclable nature aligns with the trend of green logistics. At trade shows and commercial exhibitions, the airplane box is widely used due to its unique design and strong printing capabilities. Merchants can use it to package exhibits or carry promotional materials to attract attention and convey brand information.
[0003] Existing aircraft boxes typically rely on filling with foam of a fixed size or fixed paper trays, which cannot be adapted to products of different sizes. Changing products requires re-molding, and they rely only on side cardboard for support, lacking a supporting inner lining, resulting in poor support stability. Therefore, we propose a fixed inner lining aircraft box. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] like Figures 1-4 As shown;
[0024] The fixed-lined aircraft case includes an aircraft case body 1, a fixed inner liner 6, and an elastic inner liner 7. The fixed inner liner 6 is fixed to the inner wall of the aircraft case body 1. At least one layer of elastic inner liner 7 or a partitioned inner liner 8 is placed on the inner side of the fixed inner liner 6. A partition block 9 is fixed inside the partitioned inner liner 8. A box cover 2 is fixedly connected to one end of the aircraft case body 1. A fixing plate 3 is fixed to one end of the box cover 2. Plug-in buckles 4 are fixed to both sides of the fixing plate 3. Plug-in slots 5 are provided on both sides of one end of the aircraft case body 1.
[0025] In this implementation plan: by layering elastic inner lining 7 or partition blocks 9, it can adapt to products of any size and quantity without the need for mold opening, solving the problem of poor versatility of traditional foam padding, reducing customization costs, fixing the inner lining 6 frame to enhance the rigidity of the box body and prevent side wall deformation, and the thick sponge inner lining absorbs the vibration energy during transportation.
[0026] In an optional embodiment, the fixed liner 6 and the aircraft box body 1 are a fixed integral structure, and the dimensions of the fixed liner 6 and the four inner walls of the aircraft box body 1 are matched.
[0027] In this implementation plan: the fixed inner lining 6 frame enhances the rigidity of the box and prevents side wall deformation.
[0028] In an optional embodiment, both the elastic liner 7 and the partition liner 8 are detachably connected to the aircraft box body 1, and both the elastic liner 7 and the partition liner 8 are thick sponge material layered structures.
[0029] In this implementation plan: the elastic liner 7 and the partitioned liner 8 support pre-production and rapid assembly on demand. By stacking the elastic liner 7 or the partition block 9, it can adapt to products of any size and quantity without mold opening, solving the problem of poor versatility of traditional foam pads. The thick sponge liner absorbs the vibration energy during transportation.
[0030] In an optional embodiment, the snap fastener 4 corresponds to the snap slot 5, and the snap fastener 4 and the snap slot 5 engage and lock.
[0031] In this implementation scheme, the interlocking structure of the plug buckle 4 and the plug groove 5 disperses the top pressure, thus improving the compressive strength compared to the traditional plug tongue box.
[0032] In an optional embodiment, a visible film 10 is embedded in the box cover 2, and an anti-counterfeiting seal 12 is covered on the visible film 10. A tearable line 11 is provided at half of the connection between the anti-counterfeiting seal 12 and the box cover 2.
[0033] In this implementation plan: a semi-covered anti-counterfeiting seal 12 prevents unauthorized opening and is used in conjunction with a visible film 10 for inspection.
[0034] In an optional embodiment, the anti-counterfeiting seal 12 is detachably connected to the box cover 2 via a tear-away line 11, and the anti-counterfeiting seal 12 is sized to match the visible film 10.
[0035] In this implementation plan: after removing the sealing plate, it is converted into an open display box, which increases the packaging reuse rate and reduces waste.
[0036] Working principle: The fixed inner liner 6 serves as the basic frame, fitting against the inner wall of the box to provide basic support. The elastic inner liner 7 or the partitioned inner liner 8 is installed according to the product size. The elastic inner liner 7 can be stacked inside the fixed inner liner 6, adjusting the number of layers to match different product sizes. The partitioned inner liner 8 has built-in dividers 9, dividing the product into multiple independent compartments to prevent collisions, such as suitable for placing glass bottles side-by-side. Furthermore, the partitioned inner liner 8 comes in various sizes and contains different numbers of dividers 9. Both the elastic inner liner 7 and the partitioned inner liner 8 are made of thick sponge material, which absorbs impact energy during transportation and carrying. Then, the box lid 2 is connected to the fixed plate 3 on both sides... The extension buckle 4 is inserted into the box body's insertion slot 5 to form a rigid lock, preventing it from popping open during transportation. At the same time, the interlocking structure of the buckle 4 and the slot can disperse external impact force and improve overall pressure resistance. Finally, the visible film 10 embedded in the transparent window of the box cover 2 allows consumers to check the condition of the unopened product. The anti-counterfeiting seal 12 is initially in a half-open state, allowing observation of the interior through the visible film 10. At the same time, the part covered by the seal forms an anti-counterfeiting barrier. After subsequent use, the seal is torn open along the pre-set tear line 11, and the anti-counterfeiting is invalidated. The visible film 10 is in a fully open state. The airplane box can be used as a display box or as a cosmetic storage box, realizing packaging reuse.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
