Description

Technical Field

[0001] This utility model relates to the technical field of foam packaging box devices, specifically to a foam packaging box that can enhance pressure resistance. Background Technology

[0002] Foam packaging boxes are widely used in logistics and product packaging due to their advantages such as light weight, good cushioning, and low cost. Traditional foam packaging boxes often employ a simple box body and lid structure, resulting in insufficient overall pressure resistance. In stacked transportation scenarios, the box body relies solely on its own wall thickness to withstand longitudinal pressure, concentrating the stress on the side walls and top surface, making it prone to dents, deformation, and even breakage, leading to damage to the internal goods. Some improved designs increase the foam wall thickness to enhance strength, but this increases material consumption and packaging weight, and has limited effect on dispersing longitudinal stacking pressure, making it difficult to meet the pressure resistance requirements of bulk transportation and failing to effectively solve the core problem of poor stacking stability. Utility Model Content

[0025] Combined with appendix Figure 1 To be continued Figure 7 A foam packaging box with enhanced pressure resistance includes a box body 1 and a top cover 2 made of foam material. The box body 1 has an opening at the top, and the top cover 2 is snap-fitted to the box body 1. Multiple vertical support columns 3 are fixedly provided along the edge of the bottom surface inside the box body 1. Inserted columns 4 are fixedly provided at the upper ends of the support columns 3. The bottom surface of the top cover 2 is fixedly provided with slots 5 corresponding to each inserted column 4. The slots 5 are inserted into the inserted columns 4 inside the box body 1 to form a support frame. The upper ends of the inserted columns 4 are connected to the top surface inside the slots 5 by a magnetic component. The front and rear side walls of the box body 1 are embedded and fixedly provided with corrugated reinforcing ribs 6. The magnetic component includes a magnetic button 7 fixedly provided at the upper end of the inserted column 4 and a magnetic button 2 fixedly provided at the top surface inside the slots 5. The magnetic button 7 and the magnetic button 2 attract and fix each other. The lower edge of the top cover 2 is provided with a sealing groove 9, and the upper opening of the box body 1 is provided with a sealing flange 10 that matches the sealing groove 9.

[0026] In this embodiment, as a preferred technical solution, multiple limiting protrusions 11 are fixedly provided at the four corners of the bottom of the box body 1, and a limiting groove 12 is provided on the upper surface of the upper cover 2. When multiple packaging boxes are stacked, the limiting protrusions 11 of the upper box body and the limiting groove 12 of the lower box cover are interlocked. Horizontal handles 13 are fixedly provided on both the left and right sides of the box body 1.

[0027] In this embodiment, as a preferred technical solution, the box 1 is further provided with multiple detachable partition plates 14 inside, and the inner wall of the box 1 is provided with grooves 15 for inserting the partition plates 14. The partition plates 14 are made of plastic or cardboard.

[0028] The working principle of this utility model is as follows: the support column 3, the insertion column 4 and the slot 5 are connected to form an edge support frame, which, together with the detachable partition plate 14, supports the middle part of the upper cover 2, and constructs a longitudinal pressure dispersion structure to avoid local force concentration; the wave-shaped reinforcing rib 6 and the horizontal handle 13 enhance the compression resistance of the side wall of the box 1; the magnetic button 1 7 and the magnetic button 2 are attracted and fixed, improving the engagement stability of the upper cover 2 and the box 1; when stacking, the limiting protrusion 11 and the limiting groove 12 are engaged to ensure the positioning stability of multi-layer stacking.

[0029] The usage process of this utility model is as follows: 1. According to the size of the goods, insert the detachable partition 14 into the groove 15 on the inner wall of the box 1 to divide the suitable internal storage area; at this time, the partition 14 is vertically fixed inside the box 1, and its upper end is aligned with the reserved position on the bottom surface of the top cover 2.

[0030] 2. Place the goods to be packaged into the box 1 area divided by the partition 14. Use the partition 14 to isolate the goods and prevent them from colliding with each other. At the same time, keep the partition 14 vertical to ensure the effectiveness of supporting the top cover 2.

[0031] 3. Align the top cover 2 with the opening at the top of the box 1, so that the insert 4 on the box 1 is inserted into the slot 5 of the top cover 2. The support column 3 forms an edge support frame through the docking of the insert 4 and the slot 5. At this time, the magnetic button 7 at the top of the insert 4 and the magnetic button 2 in the slot 5 attract each other, strengthening the locking and fixing of the top cover 2 and the box 1. At the same time, the sealing flange 10 of the box 1 is embedded in the sealing groove 9 of the top cover 2, improving the sealing performance.

[0032] 4. The packaging box is moved by the horizontal handles 13 on the left and right sides of the box body 1. The horizontal handles 13 assist in the handling and further reinforce the side wall structure of the box body 1. During transportation, the wave-shaped reinforcing ribs 6 enhance the compression resistance of the front and rear side walls of the box body 1. The magnetic suction component prevents the top cover 2 from loosening. The partition plate 14 continuously supports the middle of the top cover 2. The overall structure disperses the pressure during transportation.

[0033] 5. When multiple layers need to be stacked, align the limiting protrusion 11 of the upper packaging box with the limiting groove 12 of the lower packaging box so that they fit together to achieve positioning and fixation of multiple layers. At this time, the support frame, the partition plate 14 and the limiting structure work together to distribute the weight of the upper packaging box and prevent the lower box 1 and the top cover 2 from deforming. By applying force in the opposite direction to separate the top cover 2 from the box 1, the magnetic attraction force of the magnetic component is overcome, and the classified goods can be taken out from the box 1.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
