Technical Field
[0001] This utility model belongs to the field of packaging boxes, specifically, it relates to a folding packaging box for fragile items with built-in pearl cotton cushioning ribs. Background Technology
[0002] In the logistics and packaging sectors, protecting fragile items is always a critical concern. Take wine bottles, for example; they often experience complex road conditions and frequent loading and unloading operations during transport. Bumps from vehicle travel, collisions during handling, and the pressure from stacked goods can all cause wine bottles to break or break. Glassware and ceramic crafts face similar risks; their surfaces are typically fragile, and they are easily cracked or shattered by impacts or vibrations.
[0003] Traditional packaging methods typically use simple foam or cardboard for cushioning. However, these materials have significant limitations in cushioning performance. For example, ordinary foam is easily compressed and deformed under significant impact, losing its cushioning ability; while cardboard softens easily in humid environments, failing to provide stable support. These materials struggle to effectively absorb impact energy during transportation, especially when faced with high-intensity vibrations or collisions, where their protective effect is greatly reduced.
[0004] Furthermore, traditional packaging structures often lack precise positioning and multi-dimensional protection for fragile items. In actual transportation scenarios, fragile items such as wine bottles may shift within the packaging box due to sudden braking, turning, or shaking during loading and unloading. Because there are insufficient securing devices inside the box, the items move around, increasing the risk of damage. For example, during long-distance transportation, goods may be handled and stacked multiple times; if wine bottles are not effectively secured within the packaging box, they can easily collide with each other during these operations, leading to damage.
[0005] In view of this, this utility model is hereby proposed. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a foldable packaging box for fragile items with built-in pearl cotton cushioning ribs, thus solving the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0008] A folding packaging box for fragile items with built-in pearl cotton cushioning ribs includes: a packaging box body, wherein pearl cotton cushioning ribs are provided inside the packaging box body, and the pearl cotton cushioning ribs have a raised structure facing the inside of the packaging box body.
[0009] A positioning box is fixedly connected to one side of the inner wall of the packaging box. A through groove is opened on one side of the positioning box. Relative rubber positioning mechanisms are fixedly connected to both sides of the inner wall of the packaging box.
[0010] The rubber positioning mechanism includes a first rubber strip arranged in a straight line on the lower sides of the inner wall of the packaging box and a second rubber strip arranged in a straight line on the upper sides of the inner wall of the packaging box, with a space between the first rubber strip and the second rubber strip.
[0011] Optionally, the packaging box body includes a bottom plate, a front side plate is fixedly connected to the first side of the bottom plate, a rear side plate is fixedly connected to the second side of the bottom plate, a first triangular plate is fixedly connected to each of the two edges between the front and rear side plates, a left side plate and a right side plate are fixedly connected between the two opposing first triangular plates and the bottom plate, a cover plate is fixedly connected to one side of the rear side plate, and a locking plate is fixedly connected to one side of the cover plate.
[0012] Optionally, both the left and right side panels are made of two second triangular plates that are fixedly connected to the first triangular plate. A straight plate is fixedly connected between two adjacent second triangular plates. When the packaging box is folded, the left and right side panels form a trapezoidal structure, and the first and second rubber strips are fixedly connected to the straight plate.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0017] This invention provides reliable cushioning protection for transporting fragile items through the use of a first and second rubber strip. In use, the bottle is placed in the space between the first and second rubber strips. The bottle initially presses down on the first rubber strip, utilizing its elastic deformation to absorb shock from below. When the bottle moves up and down during transport, it comes into contact with the second rubber strip, further enhancing its shock-absorbing effect and effectively reducing the impact of vibrations on the bottle. Alternatively, the bottle can be placed on top of the first rubber strip, which is then pressed down and bent. In this case, when the bottle sways left and right, the first rubber strip blocks its lateral movement; while when the bottle moves up and down or forward and backward, the pearl cotton cushioning ribs absorb vibration energy, providing comprehensive protection against damage. This design fully utilizes the elasticity of the rubber strips and the cushioning properties of the pearl cotton, achieving multi-dimensional protection for fragile items and effectively reducing the risk of damage during transportation.

Detailed Implementation
[0028] The present invention will now be described in further detail with reference to the accompanying drawings.
[0029] Please see Figure 1-5 As shown, this embodiment provides a fragile item folding packaging box with built-in pearl cotton cushioning ribs, including a packaging box body 1, and pearl cotton cushioning ribs 2 are provided inside the packaging box body 1, and the pearl cotton cushioning ribs 2 have a raised structure facing the inside of the packaging box body.
[0030] A positioning box 3 is fixedly connected to one side of the inner wall of the packaging box body 1. A through groove is provided on one side of the positioning box 3. Oppositely arranged rubber positioning mechanisms are fixedly connected to both sides of the inner wall of the packaging box body 1. The positioning box 3 is designed using three interconnected cardboard pieces. These three cardboard pieces are cleverly combined to form a box for securing and positioning fragile items. The connection method between the cardboard pieces allows for relative bending movements, which is key to achieving the folding function of the entire packaging box. In particular, the connection between the cardboard and the rear side panel 8 is also designed as a bendable structure, allowing the cardboard to fold along this bending point when folding the packaging box, thereby reducing the overall volume of the packaging box and facilitating transportation and storage. It should be noted that the positioning box 3 is for placing the neck of the wine bottle.
[0031] The rubber positioning mechanism includes a first rubber strip 4 arranged in a straight line on the lower sides of the inner wall of the packaging box and a second rubber strip 5 arranged in a straight line on the upper sides of the inner wall of the packaging box, with a space between the first rubber strip 4 and the second rubber strip 5.
[0032] This invention provides reliable cushioning protection for transporting fragile items such as wine bottles by incorporating a first rubber strip 4 and a second rubber strip 5. In use, the bottle is placed in the space between the first rubber strip 4 and the second rubber strip 5. The bottle initially presses down on the first rubber strip 4, utilizing its elastic deformation to absorb shock from below. When the bottle moves up and down during transport, it comes into contact with the second rubber strip 5, further enhancing its shock-absorbing effect and effectively reducing the impact of vibrations on the bottle. Alternatively, the bottle can be placed on top of the first rubber strip 4, in which case the first rubber strip 4 is pressed down and bent. In this case, when the bottle sways left and right, the first rubber strip 4 blocks its lateral movement; while when the bottle moves up and down or forward and backward, the pearl cotton cushioning ribs 2 act as buffers, further absorbing vibration energy and providing comprehensive protection against damage. This design fully utilizes the elasticity of the rubber strips and the cushioning properties of the pearl cotton, achieving multi-dimensional protection for fragile items and effectively reducing the risk of damage during transportation.
[0033] In this embodiment, the packaging box body 1 includes a base plate 6. A front side plate 7 is fixedly connected to the first side of the base plate 6, and a rear side plate 8 is fixedly connected to the second side of the base plate 6. Triangular plates are fixedly connected to both edges between the front side plate 7 and the rear side plate 8. A left side plate 10 and a right side plate 11, which are fixedly connected to the base plate 6, are fixedly connected between the two opposing triangular plates. A cover plate 19 is fixedly connected to one side of the rear side plate 8, and a locking plate 12 is fixedly connected to one side of the cover plate 19. The base plate 6 serves as a basic support, the front side plate 7 and the rear side plate 8 provide front-to-back direction limits, the triangular plates enhance the structural strength of the sides, the left side plate 10 and the right side plate 11 further enclose the space, and the cover plate 19 and the locking plate 12 serve to close and lock the box. This structure ensures that the packaging box will not easily deform or fall apart during transportation, providing a stable protective space for fragile items and effectively reducing the risk of damage to fragile items due to unstable packaging structure. Each plate has bending marks at its joints, which allows the packaging box to be folded.
[0034] In this embodiment, both the left side panel 10 and the right side panel 11 are composed of two second triangular plates 13 fixedly connected to the first triangular plate 9. A straight plate 14 is fixedly connected between two adjacent second triangular plates 13. When the packaging box is folded, the left side panel 10 and the right side panel 11 form a trapezoidal structure. The first rubber strip 4 and the second rubber strip 5 are fixedly connected to the straight plate 14. The packaging box can form a stable trapezoidal structure when folded, making it easier to fold the packaging box into a more compact shape and saving storage and transportation space. At the same time, the rubber strips are fixed to the straight plate 14, which ensures that the position of the rubber strips is stable during use and better plays its role in cushioning and positioning fragile items.
[0035] In this embodiment, a first magnet 15 is fixedly connected to the upper edge of the rear side panel 8, and a second magnet 16 is fixedly connected to the upper edge of the front side panel 7. A third magnet 17 is disposed inside each of the two second triangular plates 13, and the multiple third magnets 17 are magnetically engaged with the first magnet 15 and the second magnet 16 respectively. This magnetic engagement design makes the assembly and locking of the packaging box more convenient and quick. Through the mutual attraction between the magnets, the various parts of the packaging box can be quickly fixed together, ensuring that the packaging box will not loosen or fall apart during transportation.
[0036] In this embodiment, a fourth magnet 18 is disposed above the locking plate 12, and the fourth magnet 18 and the second magnet 16 are magnetically engaged. This design further enhances the locking function of the packaging box. The engagement of the fourth magnet 18 and the second magnet 16 allows the locking plate 12 to be securely fixed to the front panel 7, forming a more reliable closed structure.
[0037] In this embodiment, the pearl cotton cushioning ribs 2 are distributed inside the front side panel 7, rear side panel 8, bottom panel 6, left side panel 10, right side panel 11, and cover panel 19. This all-around cushioning rib distribution design provides comprehensive cushioning protection for fragile items. Regardless of the direction of impact received by the fragile item inside the packaging box, the pearl cotton cushioning ribs 2 effectively absorb and disperse the impact force, reducing damage to the fragile item from vibration.
