Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a new type of environmentally friendly, miniaturized, and lightweight packaging box. Background Technology

[0002] Figure 1 This is a schematic diagram of the product structure. Product 10 includes a column 101; a tilting screen 102 is provided at the top of the column 101; bottom support legs 104 are provided at the bottom; and a platform 103 is provided in the middle of the column 101; rollers 105 are provided at the four corners of the bottom support legs 104. When packaging and transporting product 10, it is necessary to ensure that the entire product 10 is always in a stable position. Figure 1 As shown, the product must not be disassembled, folded, or bent. It must also be designed to ensure that the product can be easily removed from the packaging upon arrival at its destination.

[0003] Existing packaging and transportation solutions, such as Figure 2 As shown, the transport crate 20 is a cubic structure that meets the volume requirements of product 10, including a turnover ramp 201 located on top of the transport crate 20. The turnover ramp 201 is a structure outside the transport crate 20, used for unloading product 10 from the pallet of the transport crate 20. The turnover ramp 201 serves as a ramp for the turnover of product 10. The turnover ramp 201 is transported together with the transport crate 20. When product 10 needs to be transferred within the transport crate 20, the turnover ramp 201 connects to the bottom pallet of the transport crate 20. Through the separate turnover ramp 201, product 10 is loaded and unloaded from the bottom pallet of the transport crate 20. Although this packaging solution solves the problem of product 10 being transferred from the pallet of the transport crate 20, the overall packaging solution occupies a relatively large volume, which increases transportation costs. Furthermore, the materials typically used for transporting wooden crates 20 are plywood, foam, EPE, and pearl cotton. Before being exported to European and American markets, they require special treatments such as fumigation. Plywood and other materials present difficulties in being disposed of.

[0004] Therefore, the R&D personnel need to improve the transportation plan for product 10 in order to ensure that the materials meet environmental protection requirements and facilitate the transportation and transfer of the product. Utility Model Content

[0005] The purpose of this invention is to improve the product transportation solution so that the materials meet environmental protection requirements and have a built-in quick-deployment ramp, thereby facilitating the transportation and transfer of products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel environmentally friendly, miniaturized, and lightweight packaging box, including a bottom tray, a corrugated paper unit on the bottom tray, a first filler and a second filler on the corrugated paper unit, the corrugated paper unit, the first filler and the second filler forming a first cuboid structure that surrounds the product, and an outer box body covering the outside of the first cuboid structure. The outer casing is a second cuboid structure with an open bottom surface, including a first side surface, a second side surface, a third side surface, a fourth side surface, and a top surface; The corrugated paper unit includes a bottom surface, a first corrugated paper ramp and a second corrugated paper ramp. The first corrugated paper ramp and the second corrugated paper ramp are connected to the two ends of the bottom surface and can rotate relative to the bottom surface. The corrugated paper unit is housed in the outer box to form a semi-enclosed structure on the opposite sides of the product. The first filler is placed above the corrugated paper unit. The first filler is a hollow triangular prism structure that is laid down, including a first vertical surface, a horizontal surface and a first inclined surface. A horizontal through hole is provided on the horizontal surface, and an inclined through hole is provided on the first inclined surface. The horizontal through hole and the inclined through hole are connected. The second filler is disposed on one side of the first filler. The second filler is a quadrangular prism structure, including a second inclined surface parallel to the first inclined surface.

[0007] Preferably, a first and a second baffle are arranged parallel to each other on both sides of the first corrugated paper slope, and a third and a fourth baffle are arranged parallel to each other on both sides of the second corrugated paper slope; the cross-sections of the first, second, third and fourth baffles are all U-shaped structures.

[0008] Preferably, in the packaged state, the lower parts of the first, second, third, and fourth guide bars are used to limit the rollers of the product, and the upper parts are used to limit the platform of the product.

[0009] Preferably, the first side of the outer casing is provided with an openable first hinge and a second hinge, and the third side is provided with an openable third hinge and a fourth hinge.

[0010] Preferably, in the installed state, the first inclined surface of the first filler is used to support the bottom surface of the tilted screen of the product, and the tilt angle of the first inclined surface is the same as the tilt angle of the tilted screen; the second inclined surface of the second filler is used to fit the top surface of the tilted screen, and the tilted screen is clamped between the first inclined surface and the second inclined surface.

[0011] Preferably, the cross-section of the second filler is a right trapezoid, and it also includes a second vertical surface, a lower base surface, and an upper base surface; the horizontal surface of the first filler and the upper base surface of the second filler are coplanar, and the first vertical surface and the second vertical surface are at the same height.

[0012] Preferably, the outer casing, the first filler, the second filler, and the corrugated paper unit are all made of cardboard or corrugated paper.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By designing the first and second corrugated cardboard ramps used for product transfer as foldable structures and integrating them into the outer box, an integrated ramp solution is formed. This completely eliminates the need for separate turnover ramps in traditional solutions, making the entire packaging box compact in transit, maximizing space utilization, and effectively reducing transportation space and costs.

[0014] The main structure of the packaging box, including the outer box body, the first and second fillers, and the core corrugated cardboard unit, is made of corrugated cardboard or paperboard, achieving an all-paperboard structure. This structure is not only lightweight, but also avoids materials such as plywood and foam used in traditional wooden boxes, which require fumigation and are difficult to dispose of, fully complying with environmental protection requirements and facilitating recycling.

[0015] The unpacking and product removal process is extremely simplified. Simply open the first and second hinges on the outer box, remove the second packing material, and the built-in first corrugated cardboard ramp will automatically unfold, overlapping the bottom pallet to form a stable transfer channel. No auxiliary tools are required throughout the process; a single person can easily complete the operation, enabling product unloading and short-distance transfer. The operation is simple and requires no tools.

[0016] In the packaged state, the U-shaped structure of the first, second, third, and fourth baffles on the first and second corrugated paper ramps is used to lock the four rollers of the product from the bottom and limit the platform from the top, forming a constrained space that conforms to the shape of the product and prevents the product from moving or jumping during transportation.

[0017] The first filler material supports the bottom surface of the tilted screen via its first inclined surface, while the second filler material covers the top surface of the tilted screen via its second inclined surface. The two materials sandwich the tilted screen in the middle, preventing the screen from being damaged or scratched during bumps.

[0018] The U-shaped baffle has good elasticity and strength, which can absorb and disperse the impact and vibration energy generated during transportation, providing cushioning protection for the product.

[0019] During product transfer, the first and second rails on both sides of the unfolded corrugated cardboard ramp naturally form guide grooves. When the product is pulled out, the rollers at its bottom roll along these guide grooves, effectively preventing the product from sliding laterally or even falling off the ramp, thus ensuring the safety and controllability of the transfer process.

[0021] As described in the background section, Figure 1 This is a schematic diagram of the product structure to be transported according to this utility model; product 10 includes a column 101; the column 101 is provided with an inclined screen 102, a platform 103 passing through the column 101, and a bottom support leg 104 from top to bottom, and the bottom support leg 104 is provided with rollers 105 at the four corners of the bottom support leg 104. When packaging and transporting product 10, it is necessary to ensure that the entire product 10 is always in a safe position. Figure 1 The product 10 must not be disassembled, folded, or bent as shown. It must also be easily removable from the packaging upon arrival at the destination for convenient transshipment. As described in the background section... Figure 2 The transport crate 20 occupies a large volume and has high transportation costs. Moreover, the packaging materials cannot be disposed of, which does not meet the environmental protection requirements of the target market. The turnover ramp 201, as an independent structure, is transported with the transport crate 20. It needs to cross oceans during the entire transportation process. The turnover ramp 201 is very easy to be lost or confused with other turnover equipment of other specifications, so that the turnover ramp 201 corresponding to product 10 cannot be found when it is needed for transfer. Therefore, the R&D personnel need to improve the transportation plan of product 10 to achieve a more environmentally friendly and convenient transportation.

[0022] To solve the above-mentioned technical problems, this utility model proposes an environmentally friendly packaging box that, after use, is as follows: Figure 3 Axonometric view from the front. Figure 3 The diagram shows the outer box 1 located at the outermost part of the packaging box. The outer box 1 is equipped with a bottom pallet 2, which facilitates transportation using tools such as forklifts. The outer box 1 is a second cuboid structure with an open bottom surface, including a first side 11, a second side 12, a third side 13, a fourth side 14, and a top surface 15. Figure 3 The first side 11 shown includes a first hinge 111 and a second hinge 112, which can be opened separately or together.

[0023] Figure 4 for Figure 3 A structural diagram of the diagonal of the environmentally friendly packaging box; Figure 4 The diagram shows the third side 13, the fourth side 14, and the top surface 15 of the outer casing 1. The third side 13 includes a third hinge 131 and a fourth hinge 132, which can be opened separately or together. During installation, the outer casing 1 is fitted over the product 10 from above to surround the product 10.

[0024] Figure 5This is a schematic diagram of the outer box 1 of the environmentally friendly, miniaturized, and lightweight packaging box of this utility model. It can be clearly seen from the figure that the side opposite to the top surface 15 of the outer box 1 is the bottom opening 16. When the outer box 1 is installed, it surrounds the product 10 from the bottom opening 16 downwards.

[0025] Figure 6 This is a schematic diagram of the structure of the first filler 3 of the environmentally friendly, miniaturized, and lightweight packaging box of this utility model. The first filler 3 is a hollow triangular prism structure that can be laid down with its cross-section being a right triangle. It includes a first vertical surface 31, a horizontal surface 32, and a first inclined surface 34. A horizontal through hole 33 is provided on the horizontal surface 32. An inclined through hole 35 is provided on the first inclined surface 34. The horizontal through hole 33 and the inclined through hole 35 are connected, allowing the product's upright 101 to be inserted into both the horizontal surface 32 and the first inclined surface 34. During installation, the horizontal surface 32 is placed horizontally, the first vertical surface 31 is perpendicular to the horizontal surface 32, and the first inclined surface 34 allows the upright 101 to be inserted while also supporting the tilted screen 102 of the product 10. The tilt angle of the first inclined surface 34 is the same as the tilt angle of the tilted screen 102.

[0026] Figure 7 This is a schematic diagram of the structure of the second filler 4 in the environmentally friendly, miniaturized, and lightweight packaging box of this utility model. The second filler 4 is a quadrangular prism structure with a right-angled trapezoidal cross-section. The second filler 4 includes a second vertical surface 41, a lower bottom surface 42, a second inclined surface 43, and an upper bottom surface 44, which are formed by folding them sequentially. The area of ​​the upper bottom surface 44 is smaller than the area of ​​the lower bottom surface 42. In use, the upper bottom surface 44 is placed coplanar with the horizontal surface 32 of the first filler 3. The second filler 4 serves as a screen protection filler for the tilting screen 102. After the first filler 3 and the second filler 4 are placed in place, the tilting screen 102 can be held between them, thus protecting the screen. Whether to open the hinge on the first side 11 or the third side 13 depends on the position of the first filler 3. The hinge corresponding to the side furthest from the position of the first filler 3 should be opened, that is, the hinge closer to the second filler 4.

[0027] Figure 8This is a schematic diagram of the corrugated cardboard unit 5 of the environmentally friendly, miniaturized, and lightweight packaging box of this utility model. The corrugated cardboard unit 5 is formed by folding corrugated cardboard and is housed inside the outer box body 1 to form a semi-enclosed structure on opposite sides of the product 10. Specifically, it includes a first corrugated cardboard ramp 51, a second corrugated cardboard ramp 54, and a bottom surface 57 connecting the first corrugated cardboard ramp 51 and the second corrugated cardboard ramp 54. The first corrugated cardboard ramp 51 and the second corrugated cardboard ramp 54 can rotate relative to the bottom surface 57. The area and shape of the bottom surface 57 are the same as the top surface of the bottom tray 2. In use, the bottom surface 57 is placed on the bottom tray 2. The first corrugated cardboard ramp 51 includes a first baffle 52 and a second baffle 53. The first baffle 52 and the second baffle 53 are arranged in parallel and are separated. The first corrugated paper ramp 52 is located on both sides of the first corrugated paper ramp 51; the second corrugated paper ramp 54 includes a third stop bar 55 and a fourth stop bar 56, which are arranged in parallel and located on both sides of the second corrugated paper ramp 54 respectively; the cross-sections of the first stop bar 52, the second stop bar 53, the third stop bar 55 and the fourth stop bar 56 are all U-shaped structures. When the first corrugated paper ramp 51 and the second corrugated paper ramp 54 are folded to the vertical direction, they are arranged in a mirror image of each other. When vertical, the first stop bar 52, the second stop bar 53, the third stop bar 55 and the fourth stop bar 56 can limit the four rollers 105 of the product 10; when the product needs to be transferred, the first corrugated paper ramp 51 can be lowered to contact the plane to be transferred, serving as the transfer channel for the product 10.

[0028] Figure 9 This is a schematic diagram of the structure of the environmentally friendly, miniaturized, and lightweight packaging box of this utility model after the outer box body 1 is hidden; Figure 9The initial packaging is complete. The corrugated cardboard unit 5, the first filler 3, and the second filler 4 form a first cuboid structure surrounding the product 10. Only the outer box 1 needs to be fitted over the outside of the first cuboid structure. Now, place the bottom tray 2 on the installation station, and then place the corrugated cardboard unit 5 on the bottom tray 2, ensuring that the bottom surface 57 of the corrugated cardboard unit 5 is directly above and adheres to the bottom tray 2. Then, place the product 10 inside the corrugated cardboard unit 5 and on the bottom surface 57. Fold the first corrugated cardboard ramp 51 and the second corrugated cardboard ramp 54 respectively, and fold them from opposite sides of the product 10. A semi-enclosed structure is formed, with the four rollers 105 of the product respectively limited by the first stop bar 52, the second stop bar 53, the third stop bar 55, and the fourth stop bar 56. Specifically, the first stop bar 52 and the second stop bar 53 lock the two rollers 105 located on the side of the first corrugated paper ramp 51, and the third stop bar 55 and the fourth stop bar 56 lock the two rollers 105 located on the side of the second corrugated paper ramp 54. At the same time, the upper parts of the first corrugated paper ramp 51 and the second corrugated paper ramp 54 also lock the platform 103 within the area enclosed by the first stop bar 52, the second stop bar 53, the third stop bar 55, and the fourth stop bar 56. The lower parts of the first stop bar 52, the second stop bar 53, the third stop bar 55, and the fourth stop bar 56 limit the rollers 105, and the upper parts limit the platform 103, thereby improving the stability of the product 10 during transportation. Next, the first filler 3 and the second filler 4 are installed. During installation, the horizontal surface 32 of the first filler 3 is aligned with the platform 103 and slides from the second corrugated paper ramp 54 to the first corrugated paper ramp 51. During this process, the column 101 will pass through the horizontal through hole 33 and the inclined through hole 35 at the same time. The upper part of the column 101 is stuck in the first filler 3. The first inclined surface 34 is aligned with the bottom surface of the tilted screen 102 and supports the tilted screen 102. When installing the second filler 4, it is necessary to ensure that the upper bottom surface 44 is aligned with the top of the first corrugated paper ramp 51. Part of the upper bottom surface 44 is also located above the platform 103. The second inclined surface 43 is aligned with the upper side of the tilted screen 102. The second inclined surface 43, the tilted screen 102, and the first inclined surface 34 are parallel surfaces, so that the tilted screen 102 is located between the second inclined surface 43 and the first inclined surface 34, protecting the tilted screen 102 from scratches and other damage during transportation. The first vertical surface 31 and the second vertical surface 41 are set at the same height.

[0029] Figure 10 for Figure 9The diagram shows the structure of the environmentally friendly packaging box after the second filler 4 is hidden; it fully shows that the upper part of the column 101 is stuck in the first filler 3, the first inclined surface 34 fits against the bottom of the inclined screen 102 and supports the inclined screen 102; the platform 103 is stuck in the area enclosed by the upper ends of the first stop bar 52, the second stop bar 53, the third stop bar 55 and the fourth stop bar 56, and the four rollers 105 are stuck in the area enclosed by the lower ends of the first stop bar 52, the second stop bar 53, the third stop bar 55 and the fourth stop bar 56.

[0030] Figure 11 for Figure 10 The top view of the environmentally friendly packaging box concealing the first filler 3 shows that the first baffle 52, the second baffle 53, the third baffle 55 and the fourth baffle 56 are all U-shaped structures. The platform 103 is stuck in the rectangular area enclosed by the upper ends of the first baffle 52, the second baffle 53, the third baffle 55 and the fourth baffle 56, which limits and protects the platform 103 around its perimeter.

[0031] Figure 12 This is a schematic diagram of the structure of the environmentally friendly, miniaturized, and lightweight packaging box of this utility model, cut open parallel to the second side 12; Figure 9 Based on the bottom opening 16, the outer box 1 is fitted onto the product 10 from top to bottom, with the top surface 15 and the bottom surface 42 fitting together, the first side 11 fitting together with the first corrugated cardboard ramp 51, and the third side 13 fitting together with the second corrugated cardboard ramp 54. When it is necessary to remove the product 10, the first side 11 on the outer box 1 is opened, the second filler 4 protecting the tilting screen 102 is removed, the built-in first corrugated cardboard ramp 51 is lowered, and the product 10 is pulled out. The first stop bar 52 and the second stop bar 53 on the side of the first corrugated cardboard ramp 51 have a guiding function to prevent the product 10 from slipping and falling out when it is pushed out, thus preventing damage to the product 10. Specifically, when it is necessary to remove or transfer product 10, firstly open the first hinge 111 and the second hinge 112 on the first side 11 to expose the second vertical surface 41 of the second filler 4 and the first corrugated paper ramp 51; then remove the second filler 4, lower the first corrugated paper ramp 51 to form a bridge from the bottom tray 2 to the receiving surface, grab the column 101 and pull it towards the first corrugated paper ramp 51. The two rollers 105 near the first corrugated paper ramp 51 are no longer restricted by the first stop bar 52 and the second stop bar 53. After being subjected to force, they slide along the first corrugated paper ramp 51, and the rollers 105 on both sides will slide along the path restricted by the first stop bar 52 and the second stop bar 53.

[0032] This utility model is made of corrugated cardboard, is lightweight, and includes a first corrugated cardboard ramp 51, saving more space compared to the traditional wooden transport crate 20. No auxiliary tools are needed after opening; a single person can easily remove the product 10 from the bottom pallet 2. In the packaged state: the anti-collision cardboard box with corrugated cardboard ramps has the built-in first and second corrugated cardboard ramps 51 and 54 folded and placed inside the outer box body 1. The baffles on the ramps act as a limiting and protective buffer for the product during folding. In the unpacked state: with the first hinge 111 and second hinge 112 open, after removing the second filler 4, the first corrugated cardboard ramp 51 does not need to be manually unfolded; it unfolds automatically under its own weight. After unfolding the folded first corrugated cardboard ramp 51, the first baffles 52 and second baffles 53 on both sides of the first corrugated cardboard ramp 51 act as guides for the bottom rollers 105 of the product. In accordance with the direction in which product 10 is transported from the bottom pallet 2, the hinges of the outer box 1 should open or close on the side of the second filler 4. In the packaged state, the first corrugated cardboard ramp 51, the second corrugated cardboard ramp 54, and the first, second, third, and fourth baffles 52, 53, 55, and 56 of the opening structure serve to limit and buffer the product 10 during transport. The opening structure of the built-in corrugated cardboard ramp positions the product to prevent movement during transport; the baffles absorb impacts to the product 10 during transport to avoid damage; and when unfolded, the opening structure enhances the overall structural strength and, as the product 10 moves from the bottom pallet 2, restricts the rolling of the bottom rollers 105 of the product 10, preventing it from falling.
