Description

Technical Field

[0001] This utility model relates to the field of display packaging cushioning technology, and specifically to a display packaging cushioning structure. Background Technology

[0002] Traditional display cushioning packaging uses fossil fuels such as EPE / EPS for foaming and molding, which is not recyclable and cannot be biodegraded. This does not align with current environmental protection and green packaging market trends and requirements, nor does it meet the packaging material regulations of some markets. To address this, the industry has introduced corrugated cardboard as a cushioning packaging material, using structural design to create cushioning. However, existing corrugated cardboard cushioning suffers from drawbacks such as requiring manual molding, low efficiency, high product costs, inconsistent molding quality, and unadjustable protective strength. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display packaging cushioning structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A display packaging cushioning structure includes an upper paper tray and a lower paper tray formed by folding corrugated cardboard. The upper and lower paper trays are stacked together to form a cavity for placing the display. The lower paper tray includes a lower support plate and four paper tubes. The four paper tubes surround the lower support plate, and the ends of adjacent paper tubes are connected to each other by paper-plastic corner protectors. Support blocks are formed on the inner sides of the two opposite paper tubes, and the two sides of the lower support plate are connected to the support blocks on the corresponding sides. The free end of the support block is provided with holes for adjusting its support strength.

[0006] Furthermore, the free end side of the support block is also provided with a cutting line for adjusting its support strength.

[0007] Furthermore, the angle between the free end side of the support block and the horizontal plane is 70°-90°.

[0008] Furthermore, positioning blocks are provided around the bottom of the upper paper tray, and each positioning block is used to fit tightly against the display.

[0009] Furthermore, the inner sides of the paper-plastic corner protectors are respectively provided with reinforcing support structures formed by drilling holes.

[0010] Furthermore, the inner corners of the two sides of the paper-plastic corner protector are connected together by a trapezoidal interlocking structure.

[0011] Furthermore, the top of the upper paper tray is provided with independent accessory placement slots.

[0012] The present invention adopts the above technical solution and has the following beneficial effects:

[0013] 1. The main body of the packaging box is made of corrugated cardboard. The upper and lower paper trays are fixed without glue using a grid-shaped insert or trapezoidal buckle. It is environmentally friendly and meets the strength requirements. The paper-plastic molding is recyclable and biodegradable, which meets the market's green and environmentally friendly needs and trends.

[0014] 2. The four sides of the lower paper tray are designed with corrugated paper tubes, which are connected and fixed by paper-plastic corner protectors; the paper-plastic corner protectors not only serve as a connector, but also as a protective support.

[0015] 3. The lower paper tray can be designed with openings, cutting lines, support angles, and paper-plastic plug angles to adjust its cushioning strength, thus meeting different drop test and protection requirements.

[0016] 4. The bottom of the upper paper tray has a positioning block, which fits tightly and is fixed to the monitor product, improving the product's protective effect;

[0017] 5. The top of the upper paper tray has independent accessory placement slots. The space is independently divided and fixed according to the accessory specifications, which provides good protection for the accessory products and prevents them from affecting each other or shifting.

[0025] like Figure 1-6As shown, this utility model discloses a display packaging cushioning structure, comprising an upper paper tray 1 and a lower paper tray 2 formed by folding corrugated cardboard. The upper paper tray 1 and the lower paper tray 2 are stacked together to form a cavity for placing the display. The top of the upper paper tray 1 is provided with independent accessory placement slots 11, which can be used to place accessories such as stands, bases, and back covers. Each accessory is placed independently, providing good protection for the accessory products and preventing them from interfering with each other or shifting. Furthermore, positioning blocks 12 are provided around the bottom of the upper paper tray 1, and each positioning block 12 is used to fit tightly against the display, improving the protective effect of the display product.

[0026] The lower paper tray 2 includes a lower support plate 21 and four paper tubes 22. The four paper tubes 22 surround the lower support plate 21, and the ends of adjacent paper tubes 22 are connected together by paper-plastic corner protectors 24 (there can be 3 or 4 paper-plastic corner protectors 24). Support blocks 23 are formed on the inner sides of the paper tubes 22 on two opposite sides. The two sides of the lower support plate 21 are connected to the corresponding support blocks 23. Specifically, one side of the lower support plate 21 forms a support plate 211, which is supported on the corresponding support block 23, and its free end is inserted into the corresponding paper tube 22. The opening on the other opposite side of the lower support plate 21 is inserted into the corresponding support block 23.

[0027] The free end side of the support block 23 is provided with holes 231 for adjusting its supporting strength. The free end side of the support block 23 is also provided with cutting lines 232 for adjusting its supporting strength. The angle between the free end side 233 of the support block 23 and the horizontal plane is 70°-90°.

[0028] The inner sides of the paper-plastic corner protector 24 are respectively provided with reinforcing support structures 241 formed by perforation. The reinforcing support structures 241 are generally in the shape of "well", "cross", "meter", or "sun". The inner corners of the two sides of the paper-plastic corner protector 24 are connected together by trapezoidal interlocking structures 242 to form a right-angle structure, which facilitates the molding and fixing operation.

[0029] In this invention, the lower paper tray 2 can have its cushioning strength adjusted in four ways to meet different drop test and protection requirements:

[0030] 1. The support angle of support block 23 (the angle A between the free end side 233 of support block 23 and the horizontal plane) is designed to range from 70° (weak) to 90° (strongest).

[0031] 2. The strength of the free end side of the support block 23 is adjusted by the length and number of cutting lines 232: long / more cutting lines 232 (weak) ~ no cutting lines (strongest);

[0032] 3. The strength of the support block 23 is adjusted by the number of holes 231 on the free end side: large / many holes (weak) ~ no holes (strongest);

[0033] 4. Adjust the buffer strength by adjusting the strength of the paper-plastic corner protectors 24, and adjust the structural strength by adjusting the thickness of the ribs of the support structure 241, the number of holes, and the strength of the pulp raw materials.

[0034] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
