Background Technology

[0002] In the modern logistics and transportation industry, cardboard boxes are a commonly used packaging material, widely applied across various fields. However, traditional cardboard boxes have certain shortcomings in terms of cushioning performance. When cardboard boxes are subjected to collisions or compression during transportation, the contents inside are easily damaged by external impacts. For example, when transporting fragile items such as glassware, electronic products, and ceramic products, even if some cushioning materials, such as foam or sponge, are filled inside the cardboard box, the uneven distribution of these cushioning materials and the lack of effective support and compression-resistant structure of the cardboard box itself still make it difficult to avoid damage to the items.

[0003] While some existing packaging cartons incorporate cushioning structures to some extent, most are complex in design and costly to produce, hindering large-scale production and application. Furthermore, these cushioning structures are not ideal in practical use, failing to fully meet market demands for efficient and reliable packaging. Therefore, developing a packaging carton that is simple in structure, low in cost, and possesses good cushioning capabilities is of significant practical importance. Utility Model Content

Detailed Implementation

[0023] As shown in Figures 1-5, this utility model provides a packaging carton with a cushioning function, including a first box body 1 and a second box body 7 installed inside the first box body 1, and a top cover 4 is installed on the top of the first box body 1.

[0024] Support section 5 is installed between the first box 1 and the second box 7 to support the angle between the two boxes. Support section 5 includes a cushioning pad 12 installed at the bottom of the inner wall of the first box 1. L-shaped support columns 10 are installed around the outer surface of the cushioning pad 12. The outer surfaces of the four support columns 10 support the inner corners of the first box 1, and top blocks are installed at the top of each of the four support columns 10. The cushioning pad 12 can absorb impact from the bottom to a certain extent, while the L-shaped support columns 10 effectively support the inner corners of the first box 1, enhancing the overall structural strength of the carton and preventing deformation when subjected to external pressure, thus protecting the contents.

[0025] Filler section 6 is installed at the non-angled portion between the first box 1 and the second box 7. The filler section 6 is made of sponge or foam. These soft filler materials can fill the gap between the two boxes, support the second box 7 to keep it stable, further reduce the shaking of the goods during transportation, and at the same time play a good cushioning role when subjected to external impact.

[0026] The pressure-resistant part 9 is installed at the top of the support part 5 and serves to buffer pressure. The pressure-resistant part 9 includes a support plate 14, four sleeves 15, and four support rods 16. Springs 17 are installed on the inner walls of the sleeves 15, and pressure plates 18 are installed at one end of each spring 17. The support rods 16 are fixed to the pressure plates 18. The support plate 14 has mounting holes adapted to the support rods 16, and the top block installed on the support column 10 has limiting holes 11 adapted to the sleeves 15. When the packaging carton is subjected to pressure from above, the springs 17 compress and deform, absorbing the pressure. The pressure is then dispersed through the pressure plates 18 and the support rods 16, thus protecting the contents from excessive pressure damage.

[0027] In addition, a first buffer section 3 is installed on the outer surface of the first box 1, and a second buffer section 8 is installed on the inner wall of the second box 7. The first buffer section 3 and the second buffer section 8 are composed of multiple independent hollow cardboard shells. When subjected to external force, these hollow cardboard shells can absorb energy through their own deformation, thereby playing a buffering role and further enhancing the cushioning performance of the packaging carton.

[0028] Anti-pressure blocks 2 are evenly installed at the bottom of the first box 1. The cross-section of the anti-pressure blocks 2 is trapezoidal. The trapezoidal anti-pressure blocks 2 can increase the contact area with the ground, disperse the pressure from the ground, prevent the bottom of the carton from being damaged due to uneven force, and also play a certain role in preventing slippage.

[0029] The bottom of the top cover 4 is fitted with a retaining ring 13 that is compatible with the support plate 14. This design allows the top cover 4 to fit tightly with the support plate 14, enhancing the overall sealing and stability of the packaging carton and preventing the top cover from loosening during transportation, thus affecting the packaging effect.

[0030] Fabrication of the first box 1 and the second box 7: Select corrugated cardboard of appropriate thickness and strength, and fabricate the first box 1 and the second box 7 according to the design dimensions. During the fabrication process, ensure the dimensional accuracy and structural strength of the boxes to facilitate the subsequent assembly of components.

[0031] Installation of the buffer section: Multiple independent hollow cardboard boxes are arranged in a certain manner and installed on the outer surface of the first box 1 and the inner wall of the second box 7 respectively by glue or other suitable fixing methods to form the first buffer section 3 and the second buffer section 8.

[0032] Installation of anti-pressure blocks: Install the anti-pressure blocks 2 with trapezoidal cross-section evenly at the bottom of the first box 1. Adhesive can be used to stick them together to ensure that the anti-pressure blocks 2 are firmly connected to the first box 1.

[0033] Installation of the support: First, install the buffer pad 12 on the bottom of the inner wall of the first box 1. Then, install the four L-shaped support columns 10 around the outer surface of the buffer pad 12 so that the outer surface of the support columns 10 can tightly support the inner corner of the first box 1. Finally, install the top block on the top of the support column 10.

[0034] Installation of the pressure-resistant part: Install the sleeve 15 on the support plate 14, install the spring 17 on the inner wall of the sleeve 15, and connect the pressure plate 18 to one end of the spring 17. The support rod 16 is fixed to the pressure plate 18. Then, the support plate 14 is installed on the top block at the top of the support column 10 through the mounting hole and the support rod 16, so that the sleeve 15 is adapted to the limiting hole 11 on the top block, ensuring that the pressure-resistant part 9 is installed firmly.

[0035] Installation of the filling part: According to the size of the gap between the first box 1 and the second box 7 (excluding the angled part), cut a sponge or foam of appropriate size and fill it between the two boxes so that the filling part 6 can tightly fill the gap.

[0036] Installation of the top cover: Install the retaining ring 13 that is compatible with the support plate 14 at the bottom of the top cover 4, and then put the top cover 4 on the top of the first box 1 so that the retaining ring 13 and the support plate 14 fit tightly together to complete the assembly of the packaging carton.

[0037] When using the product, the user places the following items: Open the top cover 4, place the items to be packaged into the second box 7, adjust the position and shape of the filling part 6 according to the shape and size of the items, fill the gap between the two boxes, support the second box 7 to keep it stable and reduce shaking.

[0038] Packaging: Cover the top cover 4 back onto the top of the first box 1, ensuring that the retaining ring 13 and the support plate 14 fit tightly together, so that the packaging carton is in a sealed state.

[0039] Transportation and Handling: During transportation and handling, the various cushioning structures of the packaging carton will play a role. When subjected to external impacts and compression, the hollow cardboard shells of the first cushioning part 3 and the second cushioning part 8 will deform to absorb energy; the support column 10 and the cushioning pad 12 of the support part can enhance the structural strength of the carton and disperse the pressure; the spring 17 of the pressure-resistant part will compress and deform to buffer the pressure from above; the filling part will further buffer the impact force and protect the safety of the contents.
