Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to a packaging box. Background Art

[0002] Servers are high-value, precision equipment, requiring stringent packaging requirements during transportation to protect these high-precision electronic devices from damage during transport and storage. Inner packaging must utilize high-density, anti-static, moisture-proof, and shock-resistant materials, such as EPE pearl cotton and shock-absorbing bubble wrap, with multiple layers of wrapping applied to the server, particularly for vulnerable parts.

[0003] Outer packaging should be sturdy, pressure-resistant, moisture-proof, and waterproof. High-quality corrugated cardboard boxes are typically used, with an inner diameter slightly larger than the equipment size to prevent damage from shaking. However, since corrugated cardboard boxes are made of wood fibers and have a certain degree of hygroscopicity, their strength will continue to decline after they are put into use, undergoing warehousing and logistics transportation. When the strength of the corrugated cardboard box continues to decline to a certain extent, it will collapse, causing damage to the products inside. Therefore, the compressive strength of the corrugated cardboard box will weaken with changes in the environment. On the other hand, conventional corrugated cardboard boxes require sealing tape for sealing. The stickiness of the tape will damage the surface of the cardboard box when the box is opened. From these two aspects, it can be seen that current corrugated paper packaging is generally disposable and cannot be recycled multiple times.

[0004] Although the corrugated cardboard in the corrugated box has a certain cushioning performance, the cushioning performance is poor and insufficient to protect the product. Therefore, additional corresponding inner packaging padding is required to achieve the cushioning protection function. The commonly used inner packaging padding is EPE. EPE has good cushioning performance and can be used multiple times. However, given that corrugated boxes are disposable, conventional EPE is usually not integrated on the corrugated box. Usually, several independent EPEs form a complete inner packaging structure. Due to the wide variety of packaging materials involved, it is not easy to manage and recycle. As a result, the current EPE is also disposable and cannot be recycled multiple times. Summary of the Invention

[0005] The utility model aims to solve the problems that conventional corrugated paper packaging boxes absorb water during long-term storage, causing the packaged items to become damp, are easily damaged and are difficult to be recycled, and provides a packaging box with better performance and easy recycling.

[0006] To solve the above-mentioned problem, the present invention adopts a technical solution: a packaging box comprising a bottom panel, wherein a first set of opposite sides of the bottom panel are provided with a left side panel and a right side panel, respectively, and a second set of opposite sides of the bottom panel are provided with a front side panel and a rear side panel; the side edges of the left side panel and the right side panel are provided with roll-up panels, or the side edges of the front side panel and the rear side panel are provided with roll-up panels; the bottom panel, the left side panel, the right side panel, the front side panel, and the rear side panel are integrally formed as a plastic hollow panel. This solution uses plastic hollow panels as the packaging material, which has high inherent strength, stable performance, is not susceptible to moisture, and has better protective properties. Roll-up panels are also provided at the four corners, which, when folded, form a four-corner reinforced support structure, improving support and overall strength, and facilitating stacking.

[0007] As a preferred implementation of the present packaging box, a pre-pressed crease is provided at the transition between the bottom panel and the left side panel, and / or a pre-pressed crease is provided at the transition between the bottom panel and the right side panel, and / or a pre-pressed crease is provided at the transition between the bottom panel and the front side panel, and / or a pre-pressed crease is provided at the transition between the bottom panel and the rear side panel. Pre-pressing the creases on the panels facilitates subsequent folding and use.

[0008] As a preferred implementation of this packaging box, the roll plate comprises at least three sequentially connected support plates, each of which is integrally formed and features pre-stressed creases at the junctions between adjacent plates. The support plates are aligned with the interior of the packaging box. U-shaped reinforcements at the four corners of the box enhance its stacking capacity and provide excellent protection.

[0009] As a preferred implementation scheme of the present packaging box, a left top panel is provided on the side of the left side panel away from the bottom panel, and a pre-pressed fold is provided at the connecting line between the left side panel and the left top panel, and / or a right top panel is provided on the side of the right side panel away from the bottom panel, and a pre-pressed fold is provided at the connecting line between the right side panel and the right top panel.

[0010] As a preferred implementation scheme of the present packaging box, a front cover is provided on the side of the front side panel away from the bottom panel, and a pre-pressed fold is provided at the connecting line between the front cover and the front side panel, and / or a rear cover is provided on the side of the rear side panel away from the bottom panel, and a pre-pressed fold is provided at the connecting line between the rear cover and the rear side panel.

[0011] As a preferred implementation scheme of this packaging box, the roll plate is arranged on the left side plate and the right side plate, and an inner positioning hole is provided on the roll plate, and a first outer positioning hole is provided on the front side plate and the rear side plate at a position corresponding to the inner positioning hole after folding, and a male and female buckle is installed in the inner positioning hole and the first outer positioning hole; or, the roll plate is arranged on the front side plate and the rear side plate, and an inner positioning hole is provided on the roll plate, and a second outer positioning hole is provided on the left side plate and the right side plate at a position corresponding to the inner positioning hole after folding, and a male and female buckle is installed in the inner positioning hole and the second outer positioning hole.

[0012] As a preferred implementation of this packaging box, the front cover and rear cover are connected by a first Velcro fastener after folding, the front cover is secured to the left and right panels by a second Velcro fastener after folding, and the rear cover is secured to the left and right panels by a third Velcro fastener after folding. This reusable packaging box utilizes snap fasteners and Velcro fasteners to allow for multiple sealing and unpacking, eliminating the need for disposable sealing tape. This is economical and environmentally friendly, and does not damage the packaging materials during unpacking, extending the box's lifespan.

[0013] As a preferred implementation of the packaging box, buffer blocks are provided on the inner surfaces of the bottom plate, the left side plate, the right side plate, the front side plate and the rear side plate.

[0014] As a preferred implementation of the packaging box, buffer blocks are provided on the inner surfaces of the left top plate and the right top plate.

[0015] As a preferred implementation of this packaging box, the buffer block is made of EPE. The EPE buffer structure is affixed to the inner wall of the packaging box, integrating the buffer material into the packaging box body, providing excellent protection for the six sides of the product. The integration of plastic hollow board and EPE gives the packaging box excellent protection.

[0016] It can be seen from the above technical solution that the advantages of the present invention are that the present invention uses plastic hollow board as the material of the reusable packaging box, which has stable strength performance, is less affected by environmental changes, and is waterproof, so the reusable packaging box has good protection. It is die-cut and indented according to the designed box structure, and then EPE is pasted at specific positions on the inner wall of the box as a buffer block to form a six-sided buffer protection structure for the server. The inner buffer structure is formed in one piece when the outer box is formed, and a U-shaped reinforcement structure is formed at the four corners of the box when folded to form, which enhances the stacking capacity of the box in a structural way and has good protection performance. When the reusable packaging box can be stacked in higher layers, the space utilization rate of warehousing and logistics is higher, and the warehousing and logistics costs are lower, which has good economic efficiency. The four corners of the box are connected by snap buckles, and the hook and fleece sides of the Velcro are pasted on the outer wall of the box, and the box is finally sealed by Velcro. After the packaging is completed, the Velcro and snap buckle are removed, and the box becomes a flat plate, which is convenient for storage and waiting for the next use, achieving the purpose of multiple recycling, omitting the disposable sealing tape, and has good economy and environmental protection.

At this time, the roll plate 10 forms a column structure at the four corners of the bottom plate 1; then as shown in FIG. Figure 6 As shown, the left side plate 2 and the right side plate 4 are turned up along the pre-pressed fold between the left side plate 2 and the bottom plate 1, so that the left side plate 2 and the right side plate 4 are perpendicular to the bottom plate. At this time, the left side plate 2 and the right side plate 4 are in contact with the outer side surfaces of the columnar winding plates 10 on both sides, and the second outer positioning hole 12 is aligned with the inner positioning hole 11 and overlaps. Figure 7 As shown, the snap fasteners 16 are installed in the second outer positioning holes 12 and the inner positioning holes 11 on both sides, and the left side panel 2 and the right side panel 4 are fixedly connected to the columnar roll plate 10 on both sides and the front side panel 6 and the rear side panel 8. At this time, a packaging box with an upper opening is formed. At the four corners of the packaging box, the buffer blocks on the adjacent left side panel 2, front side panel 6, right side panel 4 and rear side panel 8 press against the rolled roll plate 10 to keep it in the column shape, and then as shown in FIG. Figure 8 As shown, the server 20 is placed in the packaging box, and the buffer blocks on the bottom plate 1, the left side plate 2, the front side plate 6, the right side plate 4 and the rear side plate 8 support the bottom surface and the surrounding of the server. Then, the left top plate 3 is turned inward along the pre-pressed crease between it and the left side plate 2, and the right top plate 5 is turned inward along the pre-pressed crease between it and the right side plate 4.
