Technical Field

[0001] The utility model relates to the technical field of corrugated packaging, in particular to a reinforced all-paper buffer assembly. Background Technique

[0002] With the rapid development of e-commerce and the rapid growth of the logistics industry, packaging boxes play an important role in the transportation and protection of goods. During the transportation of goods such as electronic products and ceramic handicrafts, the goods are easily damaged under the influence of forces such as extrusion, vibration and impact.

[0003] At present, the packaging boxes on the market mainly use materials such as foam plastics or airbags as buffer materials. Common buffer materials include polyethylene (EPE), polystyrene (EPS), etc. However, these materials have environmental protection problems. With the enhancement of environmental protection awareness and the improvement of the requirements for sustainable development, the environmental pollution and resource waste problems brought by traditional buffer materials have gradually emerged. At the same time, due to the characteristics of these traditional materials themselves, they will occupy a large amount of space, increase the overall packaging volume and weight when used, and the production cost is relatively high, affecting the economic benefits of enterprises.

[0004] Therefore, there is an urgent need to develop a new reinforced all-paper buffer assembly to replace traditional buffer assemblies made of plastic materials such as EPE and EPS and multi-layer high-gram-weight all-paper buffer assemblies, so as to reduce the space occupied by the buffer assembly, thereby reducing the size and volume of the packaging box and improving the transportation efficiency. Summary of the Invention

[0005] The purpose of the utility model is to provide a reinforced all-paper buffer assembly. Based on the Miura folding structure, it is folded into multiple support units to form the main buffer support body. Utilizing the stretchability, high foldability and support performance of the Miura folding structure, combined with the one-piece molding design and the outer shell to form a buffer monomer together, and through the effective combination of multiple buffer monomers to form various required buffer assemblies, so as to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0007] A reinforced all-paper buffer assembly includes at least one buffer monomer. The buffer monomer is formed by folding and bonding a corrugated cardboard through an integral molding structure along the crease line, and includes an outer shell, a buffer support body and a connecting part. One end of the outer shell and the buffer support body is connected by the connecting part, and the buffer support body is folded and stored inside the outer shell. The end of the outer shell where the connecting part is located is not closed, and the end of the outer shell away from the connecting part is closed.

[0008] Furthermore, an adhesive part extends outward from the side wall of the outer shell on the side away from the connecting part, and an adhesive layer is provided on the adhesive part.

[0009] Further, the buffer support includes a plurality of support units connected in an array, and each support unit is composed of a longitudinal support unit and a transverse support unit.

[0010] Further, the connecting portion is connected to the first transverse support unit on one side of the buffer support.

[0011] Further, the folded length of the transverse support unit is the same as its planar unfolded length, and the folded length of the longitudinal support unit is greater than twice the thickness of the corrugated cardboard used and less than its planar unfolded length.

[0012] The beneficial effects of the present utility model are as follows:

[0013] Based on the Miura folding structure, the present utility model is folded into multiple support units to form the main buffer support. By utilizing the stretchability, high foldability, and support performance of the Miura folding structure, combined with the one-piece molding design, a buffer monomer is formed together with the outer shell.

[0027] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0028] As Figures 1-8 shown, this embodiment discloses a reinforced all-paper buffer assembly, which includes at least one buffer monomer 100. The buffer monomer 100 is the smallest unit that makes up the reinforced all-paper buffer assembly. The buffer monomer 100 is formed by folding and bonding a corrugated cardboard through an integral molding structure along the crease line, and includes a housing 1, a buffer support 2 and a connecting part 3. One end of the housing 1 and the buffer support 2 is connected by the connecting part 3, and the buffer support 2 is folded and stored inside the housing 1. One end of the housing 1 where the connecting part 3 is located is not closed, and the end of the housing 1 away from the connecting part 3 is closed.

[0029] As Figure 4 shown, the length of the housing 1 is M. In the plane expansion diagram, the side wall on the side away from the connecting part 3 extends outwards to form an adhesive part 11, and an adhesive layer is provided on the adhesive part 11. The connecting part 3 is connected to the first transverse support unit 212 on one side of the buffer support 2.

[0030] As Figures 2-4 shown, the buffer support 2 includes a plurality of support units 21 connected in an array. As Figure 4 shown, all the support units 21 are connected by crease lines in sequence in the horizontal and vertical directions on the plane. Each support unit 21 is composed of a longitudinal support unit 211 and a transverse support unit 212. The plane expansion length of the transverse support unit 212 is m1, and the plane expansion length of the longitudinal support unit 211 is m2. The plane expansion structure of the buffer support 2 is a Miura folding structure. After the longitudinal support unit 211 and the transverse support unit 212 are folded forward and backward alternately along the crease line in sequence, a three-dimensional structure with strong support and buffering effects is formed. After folding, in the transverse direction of the overall structure of the buffer support 2, the folded length m'1 of the transverse support unit 212 is the same as its plane expansion length m1, and the folded length m'2 of the longitudinal support unit 211 is greater than twice the thickness of the corrugated cardboard used and less than its plane expansion length m2. This is because the plane expansion structure of the longitudinal support unit 211 will be compressed in the transverse direction of the overall structure of the buffer support 2 after folding. The maximum limit of compression is that the corrugated cardboard is folded and adhered together. At this time, the folded length m'2 of the longitudinal support unit 211 is slightly larger than twice the thickness of the corrugated cardboard used. Specifically, as Figure 2 shown by the length of m'2 in it. The reason for being slightly larger is that the corrugated cardboard has a certain rebound stress after folding, so that the two folded corrugated cardboards cannot be completely adhered. As long as the plane expansion structure of the longitudinal support unit 211 is folded, its folded length m'2 will be less than its plane expansion length m2. Specifically, asFigure 3 as shown by the length of m’2.

[0031] The buffer monomer 100 can be used alone or in pairs. For example, Figure 5 as shown, a buffer edge protector 200 is formed after a pair of buffer monomers 100-1 and 100-2 are vertically bonded in the transverse direction. The buffer edge protector 200 is a buffer component designed to protect the edge / corner position of the packaged object. For example, Figure 6 as shown is the schematic diagram of the integrally formed planar structure of the buffer edge protector 200. The buffer monomer 100-1 and the buffer monomer 100-2 are connected through the connecting portion 3-3.

[0032] For example, Figure 7 as shown is a buffer corner protector 300 formed by first vertically bonding two pairs of buffer monomers 100-1, 100-2 and 100-3, 100-4 in the transverse direction respectively and then folding them into a vertically perpendicular state and bonding. The buffer corner protector 300 is a buffer component designed to protect the sharp corner position of the packaged object. For example, Figure 8 as shown is the schematic diagram of the integrally formed planar structure of the buffer corner protector 300.
