Technical Field
[0001] This utility model relates to the field of foam box technology, and specifically discloses a foam box with protective function. Background Technology
[0002] Foam boxes are box-shaped packaging containers made of foam plastic. Foam plastic is a type of plastic with many tiny air pores inside. Foam boxes are often used for transporting fruits and packaging goods. They have advantages such as being lightweight, impact-resistant, easy to mold, aesthetically pleasing, brightly colored, energy-efficient, inexpensive, and widely used.
[0003] Foam boxes are generally closed rectangular structures or semi-closed rectangular structures with openings on two opposite sides. As packaging, foam boxes protect the items inside. Although traditional foam boxes have cushioning properties, their impact resistance relies on a single foam layer, making them prone to breakage during severe vibrations. They also have poor waterproof and moisture-proof performance, and water can easily seep through the seams. Furthermore, the structural strength of the boxes is low, making them prone to deformation when stacked. Therefore, a foam box with protective functions is needed to solve this problem. Utility Model Content
[0004] This utility model proposes a foam box with protective function. Through a double-layer structure combined with a three-dimensional reinforcement mechanism and a double honeycomb reinforcement design, it ensures load-bearing strength and cushioning protection while also having excellent impact resistance, temperature stability and sealing protection characteristics. The overall structure is compact, reasonable and lightweight.
[0005] This utility model is implemented as follows: a protective foam box includes a box body and a box lid. Both the box body and the box lid include an outer layer and an inner layer. The outer wall of the outer layer is provided with a plurality of evenly distributed through holes. A reinforcing mechanism is embedded between the outer layer and the inner layer. The reinforcing mechanism includes L-shaped reinforcing ribs provided at the four corners of the inner wall of the box body. Multiple L-shaped reinforcing ribs are fixedly connected to X-shaped reinforcing ribs located between the outer layer and the inner layer. The bottom of the box body is provided with honeycomb-shaped reinforcing ribs. The honeycomb-shaped reinforcing ribs include a first honeycomb reinforcing rib located on the upper surface of the inner layer and a second honeycomb reinforcing rib located on the lower surface of the outer layer. The grooves of the first honeycomb reinforcing ribs are filled with phase change material.
[0006] As a preferred embodiment of the protective foam box of this utility model, the outer layer and inner layer of the box body form a first groove, and the outer layer and inner layer of the box cover form a second groove that matches the first groove. The inner wall of the second groove is provided with a silicone sealing strip.
[0007] As a preferred embodiment of the protective foam box of this utility model, the outer walls of the L-shaped reinforcing ribs and X-shaped reinforcing ribs are coated with a wear-resistant layer, which is a polyurethane-nano silica composite material.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0022] Please see Figures 1-5 A protective foam box includes a box body 1 and a box lid 2. Both the box body 1 and the box lid 2 include an outer layer 101 and an inner layer 102. The outer wall of the outer layer 101 is provided with a plurality of evenly distributed through holes 103. A reinforcing mechanism is embedded between the outer layer 101 and the inner layer 102. The reinforcing mechanism includes L-shaped reinforcing ribs 3 located at the four corners of the inner wall of the box body 1. Multiple L-shaped reinforcing ribs 3 are fixedly connected with X-shaped reinforcing ribs 4 located between the outer layer 101 and the inner layer 102. The bottom of the box body 1 is provided with honeycomb reinforcing ribs. The honeycomb reinforcing ribs include a first honeycomb reinforcing rib 5 located on the upper surface of the inner layer 102 and a second honeycomb reinforcing rib 6 located on the lower surface of the outer layer 101. The groove of the first honeycomb reinforcing rib 5 is filled with a phase change material 7.
[0023] In this embodiment: The foam box of this utility model adopts a double-layer structure. The closed-cell layer absorbs high-frequency vibration, and the open-cell layer buffers low-frequency impact. L-shaped reinforcing ribs 3 are set at the four corners and cooperate with X-shaped reinforcing ribs 4 to form a three-dimensional support frame. At the same time, an inner and outer double honeycomb reinforcing rib structure is set at the bottom of the box. The first honeycomb reinforcing rib 5 is filled with phase change material 7, which gives it good temperature retention function. The through hole 103 design realizes the lightweight of the box body 1. The unique double honeycomb structure not only ensures the load-bearing strength of the box body 1, but also provides good cushioning protection for the contents. The overall structural design is reasonable and the protection function is comprehensive.
[0024] As a technical optimization of this utility model, the outer layer 101 and inner layer 102 of the box body 1 form a first slot 8, and the outer layer 101 and inner layer 102 of the box cover 2 form a second slot that matches the first slot 8. The inner wall of the second slot is provided with a silicone sealing strip.
[0025] In this embodiment, the interlocking structure of the slot, together with the silicone sealing strip, forms a labyrinthine sealing channel, which greatly improves the waterproof and dustproof performance.
[0026] As a technical optimization of this utility model, the outer walls of both the L-shaped reinforcing rib 3 and the X-shaped reinforcing rib 4 are coated with a wear-resistant layer, which is a polyurethane-nano silica composite material.
[0027] In this embodiment, a polyurethane-nano silica composite wear-resistant layer is coated on the outer wall of the L-shaped reinforcing rib 3 and the X-shaped reinforcing rib 4. This not only significantly improves the wear resistance and impact resistance of the reinforcing ribs, but also maintains the lightweight characteristics of the foam box. At the same time, the addition of nano silica enhances the adhesion and weather resistance of the coating, making the reinforcing ribs less prone to falling off or aging during long-term use.
[0028] As a technical optimization of this utility model, the phase change material 7 is a paraffin-based composite material.
[0029] In this embodiment, the phase transition temperature of the paraffin-based composite material can be precisely controlled, effectively maintaining the temperature stability inside the chamber.
[0030] As a technical optimization of this utility model, the inner wall of the outer layer 101 and the outer wall of the inner layer 102 are provided with grooves that match the L-shaped reinforcing ribs 3 and X-shaped reinforcing ribs 4. The outer layer 101, the inner layer 102, the L-shaped reinforcing ribs 3 and X-shaped reinforcing ribs 4 are connected by hot melt adhesive.
[0031] In this embodiment, the composite connection structure of groove and hot melt adhesive achieves seamless fitting between the reinforcing rib and the box 1, improving the overall structural strength and load transfer efficiency.
[0032] As a technical optimization of this utility model, the height of the first honeycomb reinforcing rib 5 is greater than the height of the second honeycomb reinforcing rib 6.
[0033] In this embodiment: the higher first honeycomb reinforcing rib 5 facilitates the filling of phase change material 7, and the lower second honeycomb reinforcing rib 6 ensures that the bottom of the box 1 remains flat and stable.
[0034] The working principle of this utility model is as follows: The foam box of this utility model adopts a double-layer structure. The closed-cell layer absorbs high-frequency vibration, and the open-cell layer buffers low-frequency impact. L-shaped reinforcing ribs 3 are set at the four corners and cooperate with X-shaped reinforcing ribs 4 to form a three-dimensional support frame. At the same time, an inner and outer double honeycomb reinforcing rib structure is set at the bottom of the box. The first honeycomb reinforcing rib 5 is filled with phase change material 7, which gives it a good temperature retention function. The through hole 103 design realizes the lightweight of the box body 1. The unique double honeycomb structure not only ensures the load-bearing strength of the box body 1, but also provides good cushioning protection for the contents. The overall structural design is reasonable and the protection function is comprehensive.
