The buffer packaging box 10 in this embodiment includes a peripheral card 20 , a cover plate 30 covering the peripheral card 20 , and a buffer packaging unit 40 disposed in the peripheral card.

The peripheral card 20 is provided with peripheral card side walls 210 enclosing a hollow cuboid, and two adjacent peripheral card side walls 210 are bent to form peripheral card edges 220 . In this embodiment, the peripheral card 20 is formed by folding corrugated cardboard. The cover plate 30 covers two opposite openings of the peripheral card 20 to form a closed cavity, and the cushioning packaging unit 40 is accommodated in the cavity.

The buffer packaging unit 40 includes an inner peripheral card 41 and a buffer member disposed in the inner peripheral card 41 . The inner peripheral card 41 is enclosed to form a cavity for accommodating, and the buffer member is arranged in the inner peripheral card 41 for placing plate-like products. Similar to the peripheral card 20, the inner card 41 is provided with an inner card side wall 410 enclosed in a hollow cuboid, the inner card 41 has openings on opposite sides, and the adjacent inner card side walls 410 are bent to form an inner wall Card edge 411. In this embodiment, the peripheral card 20 is formed by folding corrugated cardboard, and the height of the inner peripheral card 41 is the same as that of the peripheral card 20. Attached to the peripheral card side wall 210 of the peripheral card 20 , the cover plate 30 covers the inner peripheral card 41 at the same time.

The cushioning parts are arranged in each inner peripheral card 41, and are used for clamping and fixing the plate-shaped products, and play a role of buffering and protecting the plate-shaped products. In this embodiment, the buffers include corner buffers 43 and side buffers 45 . The corner buffers 43 are correspondingly arranged at the corners of the plate-shaped product, and buffer and protect the four corners of the plate-shaped product. The side buffers 45 are correspondingly arranged on the side of the plate-shaped product, which protects the side of the plate-shaped product and prevents the plate-shaped product from shaking.

In this embodiment, the corner buffer 43 includes a corner base 431 and a corner buffer 433 disposed on the corner base 431 . The corner substrate 431 is bent into an L shape, and includes a first corner substrate 431 and a second corner substrate 431 . In this embodiment, the corner substrate 431 is formed by folding corrugated cardboard, and the first corner substrate 431 is perpendicular to the second corner substrate 431 . During assembly, the first corner substrate 431 is attached to the cover plate 30 , and the second corner substrate 431 is attached to the inner peripheral card side wall 410 of the inner peripheral card 41 .

The corner buffer block 433 is fixedly connected to the inner side of the corner base plate 431 and arranged corresponding to the corner of the plate-shaped product. The corner buffer block 433 is in the shape of a bar, on which a plurality of first slots 4331 are defined, and the first slots 4331 extend along a direction parallel to the cover plate 30 . The first clamping slots 4331 of the plurality of corner buffer blocks 433 are arranged corresponding to each other, so that the plate-shaped product can be easily clamped in the first clamping slot 4331, and the two sides of the plate-shaped product are guaranteed to be vertical. In this embodiment, the cross-sectional shape of the first locking groove 4331 is a rectangle. It can be understood that the cross-sectional shape of the first locking groove 4331 can be consistent with the side shape of the plate-shaped product. In this embodiment, the corner buffer 43 is provided with a plurality of mutually parallel corner buffer blocks 433 on the first corner base plate 431 and the second corner base plate 431, which are used to adjust the corners and corners of the plate-shaped product. The sides that make up the corners are protected.

The side buffer 45 includes a side base 451 and a side buffer 453 disposed on the side base 451 . In this embodiment, the side buffers 45 are placed on the lower cover plate 30 and disposed between the two lower corner buffers 43 . At least one side buffer block 453 is disposed on the side buffer member 45 , and similarly, the side buffer block 453 is correspondingly provided with a second locking slot 4531 . The first slot 4331 of the side buffer block 453 is corresponding to the second slot 4531 of the corner buffer block 433 . Since the plate-shaped product is placed in the buffer packaging box 10 of the present invention, the inner card side wall 410 of the inner card 41 and the peripheral card side wall 210 of the peripheral card 20 are usually vertically arranged, and the plate-shaped product is also vertical. The state is inserted into the first slot 4331 of each buffer. Therefore, the center of gravity of the plate-shaped product is usually located in the middle of the box, and it is easy to shake under the impact force from the horizontal direction. By setting the side buffer 45, the side of the plate-shaped product is clamped to ensure the stability of the plate-shaped product and to form protection for the side of the plate-shaped product. Meanwhile, in this embodiment, the coverage area of the corner buffer block 433 disposed on the lower corner buffer member 43 is larger than that of the corner buffer block 433 disposed on the upper corner buffer member 43 . Thereby, the stability of the lower part of the stable plate-shaped product is strengthened, and the plate-shaped product is prevented from shaking.

It can be understood that the side buffer 45 can be disposed on any side of the plate-shaped product. In this embodiment, the corner substrate 431 of the corner buffer 43 and the side substrate 451 of the side buffer 45 are made of corrugated cardboard, and the corner buffer 433 and the side buffer 453 are made of EPE material (EPE, Expandable Polyethylene, expandable polyethylene).

The buffer packaging unit 40 is also provided with a reinforced frame 50 . The reinforcing frame 50 is strip-shaped and formed by folding cardboard. The reinforcing frame 50 is provided with folded edges along its extending direction, and the reinforced frame 50 is folded along the folded edges into strips perpendicular to each other, and its cross-sectional shape is L-shaped. The reinforcing frame 50 is provided with a vertical outer abutting surface at a right angle. During assembly, the outer abutting surface of the reinforced frame 50 is attached to the inner peripheral card edge 411 of the inner peripheral card 41, and the corner buffer block 433 is supported by the reinforced frame 50, thereby cushioning the impact resistance of the edge of the packaging box 10 . In this embodiment, the reinforcing frame 50 is arranged between the inner peripheral card 41, the corner buffer 43, and the side buffer 45, thereby preventing the corner buffer 43, the side buffer 45 from colliding with the inner peripheral card 41. There is a gap between them, which in turn causes the plate-shaped product to shake.

When the plate-shaped product is placed in the cushioning packaging unit 40 , the lower cover plate 30 is set horizontally and stably, the peripheral card 20 is placed on the cover plate 30 , and the inner peripheral card 41 is placed in the peripheral card 20 . The inner peripheral card sidewall 410 of the inner peripheral card 41 is attached to the peripheral card sidewall 210 of the peripheral card 20 . First place the corner buffer 43 and the side buffer 45 on the cover 30 , and hold a plurality of plate-shaped products in the first slot 4331 and the second slot 4531 respectively. The two opposite sides of the plate-shaped product are held against the corner buffers 43, so that the inner peripheral card 41 is closely attached to the peripheral card 20, which can prevent the gap between the inner peripheral card 41 and the peripheral card 20, and can Prevent the deformation of the inner peripheral card 41 and the peripheral card 20 . After the plate-shaped product is placed, place the corner buffer 43 above the plate-shaped product, and set the side buffer 45 as required, and finally seal the peripheral card 20 and the inner peripheral card 41 through the cover plate 30 .

In this embodiment, two cushioning packaging units 40 are provided in the peripheral card 20, so that three sides of each cushioning packaging unit 40 are attached to butt against the peripheral card side wall 210 of the peripheral card 20, and the remaining side is against the corresponding Adjacent cushioning packaging unit 40. The above settings can make the buffer packaging unit 40 resist impact and deformation under the wrapping of the peripheral card 20, and prevent the deformation of the inner peripheral card 41. When more than two buffer packaging units 40 are arranged in the peripheral card 20, the buffer packaging unit 40 may Only there is no resistance or only one side is supported against the peripheral card 20, so its overall anti-deformation ability is poor, which is not conducive to the protection of the products placed therein.

The cushioning packaging unit 40 and the cushioning packaging box 10 of the present invention combine EPE and cardboard to form corner cushioning pieces 43 and side cushioning pieces 45, saving materials, reducing costs, and meeting environmental protection requirements. For plate-shaped products with similar dimensions and the same thickness, the corner buffers 43 and side buffers 45 can be shared, and only the inner peripheral card 41 and peripheral card 20 of different sizes need to be replaced. Adopting the outer peripheral card 20 to set the double inner peripheral card 41 structure can not only increase the overall compression resistance, but also reduce the length of a single buffer and facilitate processing. By setting the reinforced frame 50, edge protection is enhanced. The cushioning packaging unit 40 and the cushioning packaging box 10 of the present invention can effectively prevent product damage during storage, transportation, and use through systematic drop tests, and through structural design, the utilization rate of the finished materials can be maximized.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.
