Description

Technical Field

[0001] The utility model relates to the field of packaging cartons, in particular to a packaging carton for fragile items. Background Technique

[0002] Packaging cartons for fragile items are usually made of corrugated paper. Corrugated paper has good compressive strength and buffering performance, which can effectively protect items from collision and extrusion during transportation. In addition, cushioning materials such as foam plastics or corrugated cardboard are usually placed inside the carton to further enhance the buffering effect.

[0003] Most of the fillers in existing packaging cartons are directly placed inside the cartons. The fillers themselves do not have stability and support. During transportation and handling, they are prone to displacement inside the carton, losing the protective performance for the items, and there is still room for improvement in the structure. Content of the Utility Model

[0027] Embodiment 1

[0028] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a packaging carton for fragile items, including an outer box body 1 and an upper cover plate 2. The upper cover plate 2 is rotatably connected to one side of the top end of the outer box body 1. There are two groups of upper cover plates 2, which are symmetrically arranged on both sides of the top end of the outer box body 1;

[0029] The first filling air column 5 is fixed to the inner walls of the front and rear ends of the paper box body 3 of the outer box body 1, and plays a role in shock absorption and protection inside the outer box body 1;

[0030] The middle-section hollow air column 10 is fixed between the two groups of outer-layer hollow air columns 9 of the first filling air column 5, and plays a role in middle-section support and explosion prevention inside the first filling air column 5;

[0031] A large number of air columns are filled inside the packaging carton to ensure the overall support and shock absorption. Fragile items placed therein, including glass, ceramics, etc., can be well wrapped. Moreover, the first filling air column 5 inside has strong structural strength and will not be bent or deformed under external impact.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, the outer box body 1 includes a paper box body 3, reinforcing corner protectors 4, a first filling air column 5, and a second filling air column 6. The reinforcing corner protectors 4 are fixedly connected to the bottom end of the paper box body 3. There are four groups of reinforcing corner protectors 4, which are symmetrically arranged at the four corners of the bottom end of the paper box body 3. The first filling air column 5 is fixedly connected to the inner walls of the front and rear ends of the paper box body 3, and the second filling air column 6 is fixedly connected to the inner walls of the left and right ends of the paper box body 3;

[0034] The connection part of the first filling air column 5 and the second filling air column 6 of the outer box body 1 is designed in a staggered manner;

[0035] The upper cover plate 2 includes a paper cover plate 7 and a solid foam 8, and the solid foam 8 is fixedly connected to the surface of the paper cover plate 7;

[0036] The first filling air column 5 and the second filling air column 6 with an interleaved design can protect the edges of fragile items. When in use, place the fragile item inside the paper box 3, and clamp and protect the fragile item by squeezing the first filling air column 5 and the second filling air column 6. The use of the reinforcing corner guard 4 can ensure good support and protection for the edges of the paper box 3 during transportation, reducing the breakage of fragile items caused by the deformation of the paper box 3. After placing the fragile item inside the paper box 3, fold the upper cover plate 2 inward so that the solid foam 8 covers the surface of the fragile item, improving the anti-impact ability. Even when there is a situation of heavy objects stacking during transportation, it can play a good role in buffering and decompression.

[0037] Embodiment III

[0038] On the basis of Embodiment I, the first filling air column 5 includes an outer-layer hollow air column 9, a middle-section hollow air column 10, a solid plastic support rod 11, and an X-shaped plastic plate 12. Both the top and the bottom of the middle-section hollow air column 10 are fixedly connected to the outer-layer hollow air column 9. A plurality of groups of solid plastic support rods 11 are fixedly connected to the inner wall of the outer-layer hollow air column 9, and a plurality of groups of X-shaped plastic plates 12 are fixedly connected to the inner wall of the middle-section hollow air column 10;

[0039] The first filling air column 5 and the second filling air column 6 have the same structure;

[0040] When protecting fragile items, it is mainly the middle-section hollow air column 10 that comes into contact with the fragile items. The X-shaped plastic plates 12 inside the middle-section hollow air column 10 play a good role in facilitating fitting. Each group of X-shaped plastic plates 12 has independent support, which can ensure that the air inside the air column supports the fragile items. The outer-layer hollow air column 9 mainly plays an overall support role. The solid plastic support rods 11 inside the outer-layer hollow air column 9 have strong structural strength. When there is shaking or displacement during transportation, the solid plastic support rods 11 can ensure the stability of the outer-layer hollow air column 9, reduce the displacement of the fragile items inside the air column, and improve the stability;

[0041] The reinforcing corner guard 4 includes a plastic corner guard 13 and an adhesive layer 14. The adhesive layer 14 is pasted on the inner wall of the plastic corner guard 13, and the adhesive layer 14 is provided with three groups and is arranged on the three groups of inner walls of the plastic corner guard 13;

[0042] After the upper cover plate 2 is closed, the reinforcing corner guards 4 can be pasted at the connection between the upper cover plate 2 and the external box body 1. During transportation and handling, a total of eight groups of reinforcing corner guards 4 can effectively protect the most vulnerable outer corners of the carton. Moreover, the installation method of the reinforcing corner guards 4 by pasting is relatively simple and the cost is relatively low.

[0043] Those of ordinary skill in the art should understand that the discussion of any above embodiment is only exemplary and is not intended to imply that the scope of the present invention includes the claims being limited to these examples; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above, and they are not provided in detail for the sake of brevity.
