DETAILED DESCRIPTION

[0030] The following is only a preferred embodiment of the present application, and does not limit the protection scope of the present application.

[0031] A buffer environment-friendly carton, such as Figures 1 to 7As shown, it includes a carton body 1 and a carton cover 2 covered on the carton body 1, and is characterized in that: a buffer mechanism is arranged in the carton body 1, the buffer mechanism includes a buffer frame 3, an automatic pressure relief valve 5, a one-way inflation valve 6 and five buffer air cushions 4, the buffer frame 3 is a rectangular frame with a hollow interior, and a buffer air cushion 4 is arranged on the bottom and four sides of the buffer frame 3, and each buffer air cushion 4 is respectively connected to the interior of the buffer frame 3, the automatic pressure relief valve 5 and the one-way inflation valve 6 are respectively arranged on the buffer frame 3, and the carton cover 2 includes cardboard 21 and a buffer pad 22, the buffer pad 22 is fixedly installed on the lower end surface of the cardboard 21, the cardboard 21 is covered on the upper part of the carton body 1, and the buffer pad 22 is inserted into the carton body 1. The traditional cushioning environmentally friendly carton increases the cushioning performance by built-in springs or air cushions, but the air cushions are pre-inflated. When the contents shake and impact the air cushions, the pressure in the air cushions increases instantly. When the pressure is greater than the maximum bearing pressure of the air cushions, the air cushions will rupture, causing air to be lost, and the air cushions will lose their cushioning performance. The reliability and stability are poor, and it is difficult to protect heavier contents. The utility model supports the interior of the carton body 1 through the cushioning frame 3 to improve the structural strength of the carton body 1; cushions the contents through the cushioning air cushions 4. When the contents impact the cushioning air cushions under shaking, Pad 4, when the internal pressure of the buffer air cushion 4 increases to the limit value of the buffer air cushion 4, the automatic pressure relief valve 5 relieves the pressure of the buffer air cushion 4 to prevent the internal pressure of the buffer air cushion 4 from being too high and causing the buffer air cushion 4 to rupture, and to avoid all the air in the buffer air cushion 4 being discharged, thereby improving the buffering performance, extending the service life of the buffer air cushion 4, and improving reliability and stability; the buffer air cushion 4 is inflated by the one-way inflation valve 6, so that the buffer air cushion 4 can be reused, and the environmental protection performance is improved. The buffer air cushion 4 is built into the buffer environmental protection carton, and there is no need to wrap the contents, thereby improving packaging efficiency and making it more convenient to use.

[0032] Specifically, each cushion 4 includes a plurality of first air columns 41 and a plurality of second air columns 42, each of which is vertically staggered to form a mesh cushion 4. Both ends of each first air column 41 and each second air column 42 are connected to the cushion frame 3 and communicate with the interior of the cushion frame 3. The mesh cushion 4 allows space for elastic deformation when squeezed, further preventing rupture of the cushion 4.

[0033] Specifically, elastic support columns 43 are provided inside each connection between the first air column 41 and the second air column 42. When the cushioning air cushion 4 is squeezed and some air is expelled through the automatic pressure relief valve 5, the elastic support columns 43 elastically recover after being squeezed, thereby generating a pressure difference between the cushioning air cushion 4 and the atmosphere, automatically opening the one-way inflation valve 6 to draw air into the cushioning air cushion 4, achieving automatic air replenishment, thereby ensuring sufficient air in the cushioning air cushion 4 and preventing a decrease in cushioning performance.

[0034] Specifically, the carton body 1 is further provided with a stab-proof inner lining 11 and a stab-proof outer lining 12, and the buffer frame 3 is disposed between the stab-proof inner lining 11 and the stab-proof outer lining 12. The stab-proof inner lining 11 and the stab-proof outer lining 12 protect the inner and outer sides of the buffer mechanism respectively, preventing sharp objects from penetrating the buffer air cushion 4, thereby improving reliability and stability. The stab-proof inner lining 11 can also isolate the gaps in the mesh-shaped buffer air cushion 4, preventing small objects from entering the gaps in the buffer air cushion 4.

[0035] Specifically, the stab-resistant inner liner 11 and the stab-resistant outer liner 12 are both canvas bags. The upper edge of the stab-resistant inner liner 11 is fixedly mounted to the inner side of the upper portion of the buffer frame 3, while the upper edge of the stab-resistant outer liner 12 is fixedly mounted to the outer side of the upper portion of the buffer frame 3. The canvas bag has high puncture resistance and is flexible enough to fit snugly on the buffer air cushion 4. Only the upper edge of the stab-resistant inner liner 11 is fixedly connected to the buffer frame 3. During use, the stab-resistant inner liner 11 can be flipped outward for cleaning, making it convenient to use.

[0036] Specifically, if Figure 6 As shown, the automatic pressure relief valve 5 includes a pressure relief valve body 51, a pressure relief sealing gasket 52, a pressure relief valve stem 53, a pressure relief spring 54 and an adjusting plate 55. The pressure relief valve body 51 is fixedly installed on the buffer frame 3. A pressure relief installation cavity 511 is provided inside the pressure relief valve body 51. The pressure relief installation cavity 511 is provided with a plurality of internal pressure relief ports 512 connecting the pressure relief installation cavity 511 and the inner cavity of the buffer frame 3 on the side facing the buffer frame 3. The outer wall of the adjusting plate 55 is provided with an external thread, and the inner wall of the pressure relief installation cavity 511 is provided with an internal thread. The adjusting plate 55 is threadedly connected to the pressure relief installation cavity 511. Cavity 511, the center of the adjusting plate 55 is provided with a through-rod hole 551, and the periphery of the through-rod hole 551 is provided with an external pressure relief port 552 connecting the pressure relief installation cavity 511 and the atmosphere, the pressure relief valve stem 53 is passed through the through-rod hole 551, the pressure relief sealing gasket 52 is fixedly installed on the inner end portion of the pressure relief valve stem 53 and is sealed with each internal pressure relief port 512, the pressure relief spring 54 is sleeved on the pressure relief valve stem 53, one end of the pressure relief spring 54 presses against the pressure relief sealing gasket 52, and the other end presses against the adjusting plate 55, and the inner wall of the pressure relief installation cavity 511 is also provided with a plurality of pressure relief grooves 513. When the contents impact the buffer air cushion 4 under shaking, and the internal pressure of the buffer air cushion 4 increases to the limit value of the buffer air cushion 4, the internal pressure of the buffer air cushion 4 pushes the pressure relief sealing pad 52 to move outward and compresses the pressure relief spring 54, and the pressure relief sealing pad 52 moves away from the internal pressure relief port 512. The air in the buffer air cushion 4 enters the pressure relief mounting cavity 511 from the internal pressure relief port 512, and then passes through the pressure relief sealing pad 52 through the pressure relief groove 513 and is discharged into the atmosphere from the external pressure relief port 552; by rotating the adjustment plate 55, the distance between the adjustment plate 55 and the pressure relief sealing pad 52 is adjusted to adjust the elastic pressure of the pressure relief spring 54, thereby controlling the deformation of the buffer air cushion 4 to adjust the buffering force, which can adapt to the loading requirements of different contents.

[0037] Specifically, if Figure 7 As shown, the one-way inflation valve 6 includes an inflation valve body 61, an inflation valve stem 62, an inflation sealing pad 63, an inflation spring 64 and an inflation limit plate 65. The inflation valve body 61 is fixedly installed on the buffer frame 3. An inflation installation cavity 611 is provided inside the inflation valve body 61. The inflation installation cavity 611 is provided with a pressure relief slide hole 612 and multiple internal inflation ports 613 on the side facing the buffer frame 3. The pressure relief slide hole 612 and each internal inflation port 613 are respectively connected to the inflation installation cavity 61 1 and the inner cavity of the buffer frame 3, the inflation valve stem 62 is inserted into the pressure relief slide hole 612, the inflation sealing pad 63 is arranged at the inner end of the inflation valve stem 62, the inflation limit plate 65 is arranged at the outer end of the inflation valve stem 62, and the inflation spring 64 is sleeved on the inflation valve stem 62, one end of the inflation spring 64 abuts against the inner wall of the inflation installation cavity 611, and the other end abuts against the limit plate. The outer side surface of the inflation valve body 61 is also provided with an external inflation port 614 that connects the inflation installation cavity 611 and the atmosphere. During inflation, the inflation tube is inserted into the inflation mounting cavity 611 from the external inflation port 614 for inflation. As the pressure in the inflation mounting cavity 611 increases, the inflation sealing cushion 63 moves inward, thereby making the inflation sealing cushion 63 away from the internal inflation port 613, and the air in the inflation mounting cavity 611 enters the buffer air cushion 4 through the internal inflation port 613. After inflation is completed, the inflation sealing cushion 63 is reset under the action of the inflation spring 64, thereby sealing each internal inflation port 613 to prevent air leakage; when the elastic support column 43 is squeezed, it elastically recovers, thereby generating a pressure difference between the buffer air cushion 4 and the atmosphere, and under the action of the pressure difference, the inflation sealing cushion 63 moves inward, thereby opening the internal inflation port 613 to inhale air until the pressure in the buffer air cushion 4 is balanced with the atmospheric pressure, and the inflation sealing cushion 63 is reset under the action of the inflation spring 64, thereby sealing each internal inflation port 613.

[0038] Specifically, the buffer frame 3 is made of hard plastic, and the buffer air cushion 4 is made of rubber. The hard plastic buffer frame 3 is formed in an integrated process, which facilitates production and processing. It can support the interior of the buffer environmentally friendly carton, especially strengthening the edges and corners of the buffer environmentally friendly carton, thereby improving the structural strength of the buffer environmentally friendly carton. The rubber buffer air cushion 4 can increase structural strength and increase deformation, further improving the buffering performance.

[0039] Specifically, the carton cover 2 is further provided with a sealing tape 23, which is fixedly mounted on the upper end surface of the cardboard 21. Both ends of the sealing tape 23 extend toward the outer side surface of the carton body 1. A Velcro tape 24 is provided at each end of the sealing tape 23. A Velcro tape 13 is provided at the positions of the carton body 1 corresponding to the two Velcro tapes 24, and each Velcro tape 24 is connected to a corresponding Velcro tape 13. Traditional cushioning environmentally friendly cartons are sealed with thumbtacks or transparent tape. After unpacking, the cushioning environmentally friendly cartons will be damaged by the transparent tape or thumbtacks, resulting in a decrease in structural strength or even inability to be reused. The sealing tape 23 of the present invention fixes the carton cover 2 to the carton body 1 through the Velcro tape 13 and the Velcro tape 24, preventing damage to the carton body 1 during unpacking, facilitating reuse, and improving environmental protection. The carton cover 2 cushions the upper portion of the cushioning mechanism through a cushioning pad 22. The cushioning pad 22 is made of foam or sponge, thereby achieving all-round cushioning and improving cushioning performance.

[0040] Specifically, the sealing tape 23 is an elastic tape that can improve the connection strength between the carton cover 2 and the carton body 1 and improve the sealing performance.
