Technical Field

[0001] This utility model relates to the field of tobacco leaf turnover packaging technology, specifically to a hollow board structure for a soft plastic raw tobacco leaf recycling box. Background Technology

[0002] Currently, the common method for handling raw tobacco leaves is to wrap them in burlap and secure them with hemp rope. However, this method has poor compressive strength, making the tobacco leaves susceptible to damage during transportation and handling, resulting in significant leaf loss and increased breakage.

[0003] Therefore, there is an urgent need to provide a hollow panel structure for a soft plastic tobacco leaf recycling box to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and defects of the existing technology and provide a hollow plate structure for a soft plastic raw tobacco leaf recycling box, which effectively avoids the raw tobacco leaves from being squeezed during transportation and turnover, maintains the integrity of the raw tobacco leaves, and reduces the breakage rate.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A hollow panel structure for a soft plastic tobacco leaf recycling box includes a box body surrounded by front and rear side panels and left and right side panels. The top and bottom of the front and rear side panels are connected to a first cover plate, and the top and bottom of the left and right side panels are connected to a second cover plate. The front and rear side panels, left and right side panels, first cover plate, and second cover plate all include a first soft plastic panel and a second soft plastic panel. A hollow columnar structure is provided between the first soft plastic panel and the second soft plastic panel. The hollow columnar structure includes multiple columnar units formed by reinforcing ribs.

[0007] As a preferred embodiment of this utility model, the first and second soft plastic boards are made of food-contact grade polypropylene or polyethylene.

[0008] As a preferred embodiment of this utility model, the first soft plastic board and the second soft plastic board are the same size and thickness.

[0009] As a preferred embodiment of this utility model, the four corner ends of the first and second soft plastic boards are provided with reinforcing corner blocks.

[0010] As a preferred technical solution of this utility model, the first cover plate is provided with a first adhesive component, and the second cover plate is provided with a second adhesive component, with the first adhesive component and the second adhesive component being disposed opposite to each other.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The front and rear side panels, left and right side panels, first cover plate, and second cover plate of this utility model are all made of hollow sheet metal. This allows the raw tobacco leaf recycling box to maintain high strength while achieving a lightweight design. It ensures that the box can effectively absorb and disperse external pressure and impact during transportation and handling of the raw tobacco leaves, preventing the leaves from being crushed and breaking, effectively maintaining the integrity of the tobacco leaves and significantly reducing the breakage rate. Furthermore, the box can maintain good structural integrity even after multiple uses, eliminating the need for frequent replacements and greatly reducing packaging costs during the handling of raw tobacco leaves.

[0018] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0019] The specific implementation process of this utility model is as follows:

[0020] like Figs. 1 to 3As shown, a hollow panel structure for a soft plastic tobacco leaf recycling box includes a box body surrounded by front and rear side panels and left and right side panels. A first cover plate 1 is connected to the top and bottom of the front and rear side panels, and a second cover plate 2 is connected to the top and bottom of the left and right side panels. Each of the front and rear side panels, left and right side panels, first cover plate 1, and second cover plate 2 includes a first soft plastic panel 3 and a second soft plastic panel 4. A hollow columnar structure 5 is provided between the first soft plastic panel 3 and the second soft plastic panel 4. The hollow columnar structure 5 includes multiple columnar units 6 formed by reinforcing ribs 7. Specifically, the recycling box of this application includes a box body with openings at both the top and bottom, surrounded by front and rear side panels and left and right side panels, and a first cover plate 1 and a second cover plate 2 connected to the top and bottom of the box body. A first adhesive component 8 is provided on the first cover plate 1, and a second adhesive component 9 is provided on the second cover plate 2. The first adhesive component 8 and the second adhesive component 9 are arranged opposite to each other. First, fold the second cover plate 2, which is connected to the left and right side panels, inwards towards the inside of the box. Then, fold the first cover plate 1, which is connected to the front and rear side panels, inwards towards the inside of the box as well. The first cover plate 1 is placed on top of the second cover plate 2. The first adhesive piece 8 on the first cover plate 1 and the second adhesive piece 9 on the second cover plate 2 are aligned and bonded together, thus sealing the top and bottom of the box and forming a hollow turnover box for storing raw tobacco leaves. This ensures that the raw tobacco leaves will not fall out of the box during turnover. When the turnover is complete and the turnover box needs to be opened to remove the raw tobacco leaves, simply separate the first adhesive piece 8 and the second adhesive piece 9. The first adhesive piece 8 can be the velvet or barbed side of Velcro, and the second adhesive piece 9 can be the velvet or barbed side of Velcro that matches the first adhesive piece 8. The combination of the first adhesive piece 8 and the second adhesive piece 9 is not limited to Velcro; it only needs to make the box easy to open and close.

[0021] The front and rear side panels, left and right side panels, first cover plate 1, and second cover plate 2 of this application are all hollow sheet materials. These hollow sheet materials are made by placing a hollow columnar structure 5 between a first soft plastic sheet 3 and a second soft plastic sheet 4. The hollow columnar structure 5 can be integrally formed with the first soft plastic sheet 3 and the second soft plastic sheet 4, or it can be bonded between the first soft plastic sheet 3 and the second soft plastic sheet 4 using an adhesive. The specific implementation can be designed according to actual use, ensuring structural stability. The hollow columnar structure 5 consists of multiple columnar units 6, which are evenly distributed inside the sheet material. Each columnar unit 6 is surrounded by a reinforcing rib plate 7. This effectively enhances the load-bearing capacity of the sheet material, allowing it to better disperse stress when subjected to external forces. The thickness of the reinforcing rib plate 7 and the shape of the columnar unit 6 can be designed according to specific needs. The shape of the columnar unit 6 includes, but is not limited to, polygons such as circles, hexagons, and pentagons, to ensure sufficient strength and stability of the sheet material under pressure. The first soft plastic board 3 and the second soft plastic board 4 are the same size and thickness. They are made of lightweight, high-strength food-contact grade polypropylene or polyethylene and other plastic materials. They have excellent waterproof and moisture-proof properties and can effectively prevent tobacco leaves from becoming moldy during turnover.

[0022] The four corners of the first soft plastic board 3 and the second soft plastic board 4 are equipped with reinforcing corner blocks 10, which further enhance the strength of the hollow board structure, thereby increasing the load-bearing capacity of the box. This application achieves lightweighting of the raw tobacco leaf recycling box while maintaining high strength, ensuring that the box can effectively absorb and disperse external pressure and impact during transportation and turnover of the raw tobacco leaves, preventing the leaves from being crushed and breaking, effectively maintaining the integrity of the tobacco leaves, and significantly reducing the breakage rate. At the same time, the box can maintain good structural integrity after multiple uses, eliminating the need for frequent replacements and greatly reducing packaging costs during the turnover of raw tobacco leaves.

[0023] The embodiments described above are merely illustrative of the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
