In consumer electronics, especially larger electronic products such as monitors and all-in-one computers, corrugated outer packaging boxes are used, in combination with buffer pads. In the prior art, EPE and EPS materials are usually used to make buffer pads, but the materials are relatively expensive, not suitable for recycling and reuse, not easily degradable in the environment, and the buffer packaging made has a relatively large volume, resulting in higher transportation costs, especially for air transportation. Therefore, researching and using buffer packaging folded from corrugated cardboard has great advantages in terms of environmental protection and cost. In addition, due to the strong rigidity of corrugated cardboard, its resilience is inferior to that of buffer materials such as EPE and EPS. Therefore, researching an improved structure combining a high-elasticity film with corrugated cardboard can significantly improve the resilience of the corrugated cardboard buffer structure, making the resilience of the improved structure combining corrugated cardboard with a high-elasticity film close to or reach that of buffer materials such as EPE and EPS, and improving the buffer performance of the overall buffer packaging.

Detailed implementation manners

[0050] The accompanying drawings are only for illustrative purposes and should not be construed as a limitation of this patent;

[0051] For better illustration of this embodiment, some components in the accompanying drawings are omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific situations. The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] In this embodiment, a corrugated cardboard suspended buffer packaging device includes: a first left cushion 1, a second left cushion 2, a first right cushion 3, a second right cushion 4, and a buffer accessory box 5. High-elasticity films 6 are provided on the first left cushion 1, the second left cushion 2, the first right cushion 3, and the second right cushion 4. The first left cushion 1 and the first right cushion 3 are respectively arranged directly above the second left cushion 2 and the second right cushion 4, and the first and second left cushions 1, 2 and the first and second right cushions 3, 4 are arranged opposite to each other to form a hollow cubic suspended cavity for placing an all-in-one computer 9 and the buffer accessory box 5. The buffer accessory box 5 is composed of an inner box (not shown in the figure), an outer box body 51, and a high-elasticity film 6 provided on the outer box body 51. The inner box (not shown in the figure) is fixed in the hollow cavity of the outer box body 51 through the high-elasticity film 6.

[0053] Further, the first left cushion 1, the second left cushion 2, the first right cushion 3, the second right cushion 4, and the outer box body 51 are respectively formed by folding a one-piece corrugated cardboard after die-cutting and indentation along the folding lines.

[0054] In this embodiment, the first left cushion 1 and the first right cushion 3 are mirror-symmetrical in structure and are both composed of a cushion panel I 11, a first support wall I 12, a second support wall I 13, a first side wall I 14, a second side wall I 15, a fixed cavity I 16, and a high-elasticity film 6. The cushion panel I 11 is connected to the first support wall I 12, the second support wall I 13, the first side wall I 14, and the second side wall I 15 through folding lines I 18. One side of the cushion panel I 11 is provided with a jack I 19, and the other side is provided with the fixed cavity I 16. The high-elasticity film 6 completely covers the fixed cavity I 16 and is fixed on the cushion panel I 11 and the first support wall I 12 through an environment-friendly water-based strong adhesive 61.

[0055] Further, the fixed cavity I 16 is composed of a die-cutting line 161, a reinforcing support wall 162, and a high-elasticity film 6. The first support wall I 12 and the second support wall I 13 are both provided with folding lines I 18 and a first tongue piece 121 and a second tongue piece 131. The folding line I 18 divides the first support wall I 12 into a first support wall surface I 122 and a tongue piece 123, and the folding line I 18 divides the second support wall I 13 into a second support wall surface I 132 and a tongue piece 133. The first side wall I 14 and the second side wall I 15 are both provided with folding lines I 18 and a third tongue piece 17.

[0056] Further, the first support wall I12 is formed by folding the first support wall surface I122, the first tongue piece 123, and the third tongue piece 17 provided on the first side wall I14 and the second side wall I15 along the fold line I18. After folding, the third tongue piece 17 on the first side wall I14 and the second side wall I15 and the reinforcing support wall 162 are sandwiched between the first support wall surface I122 and the first tongue piece 123, and are fixed to the first jack 191 of the gasket panel I11 by the inserting tongue piece 121 to form a support wall of a three-layer corrugated cardboard structure; the second support wall I13 is formed by folding the second support wall surface I132, the second tongue piece 133, and the third tongue piece 17 provided on the first side wall I14 and the second side wall I15 along the fold line I18. After folding, the third tongue piece 17 on the first side wall I14 and the second side wall I15 and the reinforcing support wall 162 are sandwiched between the second support wall surface I132 and the second tongue piece 133, and are fixed to the second jack 192 of the gasket panel I11 by the inserting tongue piece 131 to form a support wall of a three-layer corrugated cardboard structure; after the above-mentioned first support wall I12 and the second support wall I13 are folded and formed, the first side wall I14 and the second side wall I15 are formed and fixed at the same time, and jointly form the hollow first left gasket and the first right gasket.

[0057] The high-elastic film 6 covering the fixed cavity I16 and fixed to the gasket panel I11 and the first support wall I12 by the environmentally friendly water-based strong adhesive 61 is tightened by the folding of the gasket panel I11 and the first support wall I12 along the fold line I18. In this embodiment, when the all-in-one computer 9 is fixed in the fixed cavity I16, the high-elastic film 6 is stretched and deformed under the gravity of the all-in-one computer 9 to form the first buffer body. At the same time, the high-elastic film 6 transmits the gravity received through the environmentally friendly water-based strong adhesive 61 to the gasket panel I11 and the first support wall surface I122, so that the gravity received is evenly dispersed on the corrugated paper structure of the entire first left gasket 1 and the first right gasket 3, and the second buffer body is formed by the corrugated paper structure. The first buffer body and the second buffer body jointly form a suspended buffer structure with resilience and buffering performance close to or reaching that of buffer materials such as EPE and EPS. If the high-elastic film 6 is not provided on the structures of the first left gasket I1 and the first right gasket I3, when packaging the all-in-one computer 9, the all-in-one computer 9 directly contacts the first support wall I12 at the fixed cavity I16 of the first left gasket I1 and the first right gasket I3, and most of the gravity of the all-in-one computer 9 is concentrated on the first support wall I12, significantly reducing the resilience and buffering performance of the first left gasket 1 and the first right gasket 3.

[0058] Further, the lengths of the third tongue pieces 17 connected to the first side wall I14 and the second side wall I15 on the first left gasket 1 and the first right gasket 3 are the same, and are both half of the length of the first support wall I12 or the second support wall I13.

[0059] Furthermore, the second left gasket 2 and the second right gasket 4 are mirror-symmetric in structure, and both are composed of a gasket panel II 21, a first support wall II 22, a second support wall II 23, a first side wall II 24, a second side wall II 25, a fixed cavity II 26, and a highly elastic film 6. The gasket panel II 21 is connected to the first support wall II 22, the second support wall II 23, the first side wall II 24, and the second side wall II 25 through a fold line II 28. One side of the gasket panel II 21 is provided with a socket II 29, and the other side is provided with the fixed cavity II 26. The highly elastic film 6 completely covers the fixed cavity II 26 and is fixed on the gasket panel II 21 and the first support wall II 22 through an environmentally friendly water-based strong adhesive 61.

[0060] Furthermore, the fixed cavity II 26 is composed of a die-cut line two 261, a reinforcing support surface 262, and the highly elastic film 6. The first support wall II 22 and the second support wall II 23 are both provided with a fold line II 28, a tongue piece three 221, and a tongue piece four 231. The fold line II 28 divides the first support wall II 22 into a first support wall surface II 222, a tongue piece four 223, and a buffer reinforcing edge one 224. The fold line II 28 divides the second support wall II 23 into a second support wall surface II 232, a tongue piece five 233, and a buffer reinforcing edge two 234. The first side wall II 24 and the second side wall II 25 are both provided with a fold line II 28, a tongue piece six 271, and a tongue piece seven 272.

[0061] Furthermore, the first support wall II 22 is formed by folding the first support wall surface II 222, the tongue piece four 223, and the tongue piece six 271 provided on the first side wall II 24 and the second side wall II 25 through the fold line II 28, clamping the tongue piece six 271 on the first side wall II 24 and the second side wall II 25 between the first support wall surface II 222 and the tongue piece four 223, and fixing it on the socket three 291 of the gasket panel II 21 by the tongue piece three 221 to form a support wall with a four-layer corrugated cardboard structure. The second support wall II 23 is formed by folding the second support wall surface II 232, the tongue piece five 233, and the tongue piece seven 272 provided on the first side wall II 24 and the second side wall II 25 through the fold line II 28, clamping the tongue piece seven 272 on the first side wall II 24 and the second side wall II 25 between the second support wall surface II 232 and the tongue piece five 233, and fixing it on the socket four 292 of the gasket panel II 21 by the tongue piece four 231 to form a support wall with a three-layer corrugated cardboard structure.

[0062] The highly elastic film 6 covering the fixed cavity II26 and fixed on the gasket panel II21 and the first support wall II22 by the environmentally friendly water-based strong adhesive 61 is tightened by the folding of the gasket panel II21 and the first support wall II22 along the folding line II28. In this embodiment, when the all-in-one computer 9 is fixed in the fixed cavity II26, the highly elastic film 6 is stretched and deformed by the gravity of the all-in-one computer 9 to form the first buffer body. At the same time, the highly elastic film 6 transfers the received gravity to the gasket panel II21 and the first support wall surface II222 through the environmentally friendly water-based strong adhesive 61, so that the received gravity is more evenly dispersed on the corrugated paper structures of the entire second left gasket 2 and the second right gasket 4, and the second buffer body is formed by the corrugated paper structures. The first buffer body and the second buffer body together form a suspended buffer structure with a resilience and buffering performance close to or reaching that of buffer materials such as EPE and EPS. If the highly elastic film 6 is not provided on the structures of the second left gasket 2 and the second right gasket 4, when packaging the all-in-one computer 9, the all-in-one computer 9 directly contacts the first support wall II22 and the strengthened support surface 262 at the fixed cavity II26 of the second left gasket 2 and the second right gasket 4, and most of the gravity of the all-in-one computer 9 is concentrated on the first support wall II22 and the strengthened support surface 262. Although the strengthened support surface 262 is in surface contact with the all-in-one computer 9 and can disperse the force relatively well, the first support wall II22 still bears a large external force, resulting in a significant decrease in the resilience and buffering performance of the second left gasket 2 and the second right gasket 4.

[0063] Further, the tongues six 271 connected to the first side wall II24 and the second side wall II25 on the second left gasket 2 and the second right gasket 4 have the same length, and are both five-sixths of the length of the first support wall II22 or the second support wall II23; the tongues seven 272 connected to the first side wall II24 and the second side wall II25 on the second left gasket 2 and the second right gasket 4 have the same length, and are both half of the length of the first support wall II22 or the second support wall II23.

[0064] Further, the outer box body 51 of the buffer fitting box 5 is composed of a tongue piece 511, a first panel 512, a first side wall 513, a second panel 514, a second side wall 515 and a high-elasticity film 6 arranged on the second panel 514, which are sequentially connected by a semi-punched folding line 516.
