Description

Technical Field

[0001] The utility model generally relates to the technical field of transportation and storage, and in particular to a folding buffer assembly and a packaging device. Background Art

[0002] When packing fragile articles in some parts, a buffer structure capable of absorbing deformation is usually arranged in a packaging device, such as a shock-proof air column bag, foam or pearl cotton. The buffer structure made of such organic polymers has a high cost and is not environmentally friendly. In addition, there are also some paper buffer structures, such as corrugated paper or a limiting structure formed by folding paper.

[0003] The thickness of corrugated paper is limited, and the amount of deformation that can be absorbed is small. Affected by the stiffness of the paper material, the paper folding buffer structure is usually for single use. And after the folding buffer structure is bent, for example, when a crease is generated under pressure, the buffer effect that can be provided is greatly reduced. Therefore, the buffer effect that can be provided is limited. There are also some limiting structures formed by folding paper that can only provide a limiting effect to reduce the shaking of the packaged article, but need to be customized separately according to the surface shape of the packaged article, and the scope of application is limited.

[0050] The embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0051] Figure 1 The structure of the folding buffer assembly 10 in some embodiments according to the present utility model is shown. The folding buffer assembly 10 is applied to a packaging device. The following will be combined with Figure 1 to describe the folding buffer assembly 10.

[0052] As Figure 1As shown, the folding buffer assembly 10 includes at least two bearing surfaces 11 and a plurality of first elastic structures 12. There is a buffer cavity 13 between at least two bearing surfaces 11. At least two bearing surfaces 11 can be arranged parallel to each other, and the cavity between the parallel bearing surfaces 11 forms the buffer cavity 13. In some other embodiments of the present invention, the bearing surfaces 11 can also be arranged at a certain angle, or a plurality of bearing surfaces 11 can be arranged to match the shape profile of the external packaging device or the item to be packaged. For example, the bearing surface 11 is arranged parallel to the inner side surface of the packaging device, or is substantially parallel to the shape profile of the item to be packaged. It can also include a plurality of bearing surfaces 11, and the plurality of bearing surfaces 11 are arranged in a stepped shape, which is beneficial for resisting the pressure perpendicular to the bearing surface 11, or fitting the item to be packaged, and reducing the shaking amplitude of the item to be packaged in the packaging device.

[0053] The first elastic structure 12 is folded from a blank into a V shape or a Z shape, and can undergo elastic deformation under pressure. After the pressure disappears or decreases, the first elastic structure 12 can recover a certain amount of deformation. The first elastic structure 12 is arranged on the circumference of the bearing surface 11 and is connected to the edge of the bearing surface 11. For example Figure 1 as shown in the figure, the first elastic structure 12 is arranged at the edge position of the buffer cavity 13. When the bearing surface 11 is pressed, the space of the buffer cavity 13 decreases. The first elastic structure 12 is connected to the edge of the bearing surface 11. The V-shaped or Z-shaped structure compresses towards the middle as the bearing surfaces 11 approach each other and the space of the buffer cavity 13 decreases, generating deformation. At the same time, with the cooperation of the V-shaped or Z-shaped structure and the material of the first elastic structure 12 (such as paper), part of the deformation of the first elastic structure 12 is elastic deformation. After the pressure disappears or decreases, part of the deformation of the first elastic structure 12 can be restored, enabling the folding buffer assembly 10 to regain its buffering ability.

[0054] In this embodiment, at least two bearing surfaces 11 and a plurality of first elastic structures 12 are cut and folded from the same blank, which is beneficial for making full use of the blank, simplifying the processing process, and reducing the use of materials such as adhesives.

[0055] According to a preferred embodiment of the present invention, part of the first elastic structures 12 are arranged in the middle of the buffer cavity 13. When the bearing surface 11 is pressed, the buffer cavity 13 is compressed, and the position of the fold angle in the V shape or Z shape of the first elastic structure 12 rotates. The first elastic structure 12 can undergo elastic deformation, providing buffering for the compression process of the buffer cavity 13, making the pressure directly acting on the item to be packaged change slowly, and being able to absorb a certain amount of deformation to protect the item to be packaged. The first elastic structure 12 in this embodiment is folded from a blank, and the blank is, for example, corrugated paper. The elastic deformation of the first elastic structure 12 can be formed by the material of the blank and the folding structure.

[0056] As Figure 1 shown, the first elastic structure 12 in this embodiment is also disposed in the middle of the buffer cavity 13, which can provide support in the middle of the buffer cavity 13 to prevent the bearing surface 11 from undergoing excessive deformation, resulting in the loss of the buffer function or a significant decrease in the buffer capacity, and can be reused. Moreover, the first elastic structure 12 disposed in the middle of the buffer cavity 13 in this embodiment is conducive to increasing the width of the folding buffer assembly 10 and expanding the applicable range of the folding buffer assembly 10.

[0057] In this embodiment, the first elastic structure 12 located in the middle of the buffer cavity 13, at least two bearing surfaces 11, and the first elastic structures located in the circumferential direction of the bearing surface 11 can also be arranged to be cut and folded from the same blank, which is conducive to making full use of the blank, simplifying the processing process, reducing the use of materials such as adhesives, and combining the cutting and folding of the blank Figure 2 for illustration.

[0058] Figure 2 The blank 20 corresponding to at least two bearing surfaces 11 and a plurality of first elastic structures 12 in the folding buffer assembly 10 is shown, and the specific process of cutting and folding at least two bearing surfaces 11 and a plurality of first elastic structures 12 from the same blank is combined Figure 2 for illustration.

[0059] According to a preferred embodiment of the present invention, the first elastic structure 12 corresponds to the first structure sheet 21 in the blank, at least two bearing surfaces 11 include a bottom surface 111 and at least two top surfaces 112, and the buffer cavity 13 is located between the bottom surface 111 and the top surface 112. The bottom surface 111 and the top surface 112 represent relative concepts in this embodiment and do not limit the posture of the folding buffer assembly 10 when placed or used.

[0060] Among them, the bottom surface 111 corresponds to the second structure sheet 22 in the blank 20, as Figure 2 shown, the second structure sheet 22 is located in the middle of the blank 20. In this embodiment, the middle of the blank 20 is not limited to the exact center of the blank 20 and can also be other non-edge positions. Preferably, the second structure sheet 22 is located at the exact center of the blank 20, and the structure of the folding buffer assembly 10 after folding is substantially symmetrical.

[0061] The top surface 112 corresponds to the third structural sheet 23 in the blank 20. The third structural sheet 23 and the second structural sheet 22 are connected by the first structural sheet 21. For example, a die cut line or a score line is processed between the first structural sheet 21, the second structural sheet 22, and the third structural sheet 23, so that the first structural sheet 21, the second structural sheet 22, and the third structural sheet 23 can be turned and folded. In this embodiment, after the first structural sheet 21, the second structural sheet 22, and the third structural sheet 23 are folded, the bottom surface 111 and the top surface 112 are substantially opposite to each other. The first elastic structure 12 formed by folding the first structural sheet 21 is located between the bottom surface 111 and the top surface 112. When the bottom surface 111 or the top surface 112 is pressed, the first elastic structure 12 formed by folding the first structural sheet 21 undergoes elastic deformation, so that the bottom surface 111 and the top surface 112 approach each other. After the pressure disappears, a part of the deformation can be restored, and the pressure can be borne again. Moreover, the bottom surface 111 and the top surface 112 are bent under pressure, increasing the contact area with the packaged object, reducing the pressure, and realizing the buffering function.

[0062] In a preferred embodiment of the present utility model, the folding buffer assembly 10 further includes a reinforcing plate 14. The reinforcing plate 14 corresponds to the fourth structural sheet 24 in the blank 20. The fourth structural sheet 24 and the third structural sheet 23 are connected by the first structural sheet 21. As Figure 1 shown, after folding, the reinforcing plate 14 is attached to one side of the two side surfaces of the bottom surface 111 facing the buffer cavity 13. The first structural sheet 21 between the third structural sheet 23 and the fourth structural sheet 24 is folded into the first elastic structure 12. The first elastic structure 12 is located between at least two top surfaces 112 and the reinforcing plate 14 and is located in the middle of the buffer cavity 13. The reinforcing plate 14 can not only improve the compressive strength of the bottom surface 111, but also provide connection and limitation for the first elastic structure 12 arranged in the middle of the buffer cavity 13, so that the first elastic structure 12 arranged in the middle of the buffer cavity 13 can undergo elastic deformation and can restore a certain deformation after the pressure disappears.

[0063] Specifically, as Figure 1 shown, one end of the first elastic structure 12 located in the middle of the buffer cavity 13 is connected to the top surface 112, and the other end is connected to the reinforcing plate 14. The reinforcing plate 14 is attached to the bottom surface 111, and can mainly limit the compression direction of the first elastic structure 12 in the direction perpendicular to the bearing surface 11 (the bottom surface 111 and the top surface 112), preventing the first elastic structure 12 from sliding and affecting the buffering effect.

[0064] As Figure 2As shown, in the preferred embodiment of the present utility model, the blank 20 is integrally provided in a long strip shape, and the third structural sheets 23 and the fourth structural sheets 24 on both sides are bent inward, and are folded to form a folding buffer assembly 10. According to some other embodiments of the present utility model, the blank 20 can also be provided in a cross shape, the second structural sheet 22 is located in the middle, and the third structural sheets 23 and the fourth structural sheets 24 are connected to the second structural sheet 22 in four directions through the first structural sheets 21, and are all bent toward the middle to form a folding buffer assembly 10.

[0065] According to the preferred embodiment of the present utility model, the blank 20 can also be cut into other shapes, and additional die-cut lines or indentation lines are processed. After the blank 20 is folded, the folding buffer assembly 10 can be Figure 1 the shape shown in, which is generally a cuboid, including two top surfaces 112. The two top surfaces 112 are generally coplanar, the bottom surface 111 is parallel to the two top surfaces 112, and it can also be provided to include multiple top surfaces 112. For example, the cross-shaped blank 20 is folded to form four top surfaces 112, and there is a rectangular cavity between the four top surfaces 112, which can be used to fix the packaged item with a protruding cuboid structure or a curved surface. In some other embodiments, at least two top surfaces 112 can also be provided in a stepped shape. For example Figure 1 in the folding buffer assembly 10 shown in, the distances between the two top surfaces 112 and the bottom surface 111 are set to be unequal, and they are folded to form a stepped shape, or folded into other special shapes or processed into a curved surface with a certain curvature, so that the shapes of at least two top surfaces 112 match the surface shape of the packaged item, further improving the protection ability for the packaged item.

[0066] As Figure 2 shown, the first structural sheet 21 includes a first bending sheet 211 and a second bending sheet 212 that are rotatably connected. Among the first structural sheets 21 located between the second structural sheet 22 and the third structural sheet 23, the first bending sheet 211 and the second bending sheet 212 are respectively rotatably connected to the second structural sheet 22 and the third structural sheet 23. The first bending sheet 211 and the second bending sheet 212 are bent to form a V-shaped structure, and the included angle between the first bending sheet 211 and the second bending sheet 212 is set to undergo elastic deformation. At the same time, the included angles between the first bending sheet 211 and the second structural sheet 22, and between the second bending sheet 212 and the third structural sheet 23 can also undergo elastic deformation.

[0067] In the first structural sheet 21 located between the third structural sheet 23 and the fourth structural sheet 24, the first bending sheet 211 and the second bending sheet 212 are respectively rotatably connected to the third structural sheet 23 and the fourth structural sheet 24. Similarly, the angle between the first bending sheet 211 and the second bending sheet 212 can undergo elastic deformation. At the same time, the angle between the first bending sheet 211 and the third structural sheet 23, and the angle between the second bending sheet 212 and the fourth structural sheet 24 can also undergo elastic deformation.

[0068] Furthermore, as Figure 1 shown, according to the preferred embodiment of the present utility model, in the first elastic structure 12 formed by folding the first structural sheet 21, the angle between the first bending sheet 211 and the second bending sheet 212 faces the inside of the buffer cavity 13, which can prevent the first elastic structure 12 from occupying space outside the folding buffer assembly 10 and can further improve the buffering ability.

[0069] In the preferred embodiment of the present utility model, as Figure 1 shown, the folding buffer assembly 10 further includes a plurality of second elastic structures 15. The plurality of second elastic structures 15 are arranged between the bottom surface 111 and the first elastic structure 12, between the first elastic structure 12 and the top surface 112, and between the first elastic structure 12 and the reinforcing plate 14. And in this embodiment, the second elastic structures 15 and at least two bearing surfaces 11 and a plurality of first elastic structures 12 are cut and folded from the same blank. For specific cutting and folding, refer to the subsequent embodiments.

[0070] In this embodiment, setting the second elastic structures 15 can further improve the buffering ability of the folding buffer assembly 10, and the first elastic structure 12 and the second elastic structures 15 can define the minimum distance of the buffer cavity 13 to avoid direct impact on the packaged items.

[0071] According to the preferred embodiment of the present utility model, the second elastic structure 15 can be set to be in a V shape folded from the blank and facing the buffer cavity 13. As Figure 2 shown, the corresponding positions of the plurality of second elastic structures 15 in the blank 20 are the connection positions of the first bending sheet 211 and the second structural sheet 22, the connection positions of the second bending sheet 212 and the third structural sheet 23, the connection positions of the third structural sheet 23 and the first bending sheet 211, and the connection positions of the second bending sheet 212 and the fourth structural sheet 24.

[0072] Specifically, the die-cutting lines or indentation lines at the connection positions of the first bending piece 211 and the second structural piece 22, the connection positions of the second bending piece 212 and the third structural piece 23, the connection positions of the third structural piece 23 and the first bending piece 211, and the connection positions of the second bending piece 212 and the fourth structural piece 24 can be cut, and the second elastic structure 15 can be formed by folding. Further, multiple second elastic structures 15 can be provided on one die-cutting line or indentation line, preferably evenly distributed.

[0073] According to a preferred embodiment of the present utility model, as Figure 1 shown, at least two top surfaces 112 are arranged such that at least part of their edges are in contact with each other and can provide support to each other. In this embodiment, the parts of the edges of at least two top surfaces 112 that are in contact with each other are snap-connected. For example, Figure 2 as shown in, slots 25 and tongues 26 can be formed at corresponding positions on the blank 20.

[0074] As Figure 3 shown, the folding buffer assembly 10 further includes an outer cover 16. The outer cover 16 is arranged outside at least two bearing surfaces 11, and the outer cover 16 is in contact with at least two bearing surfaces 11. In this embodiment, the outer cover 16 can be made of folded paper material. The outer cover 16 can prevent the folding buffer assembly 10 from deforming due to lateral pressure, resulting in a decrease in the buffering capacity. In some other embodiments, on the side surface of the outer cover 16, for example, on the surface substantially perpendicular to the bearing surface 11, folding lines such as indentation lines can be processed, or holes can be formed, so that the outer cover 16 can be deformed more easily, changing the compressive capacity of the outer cover 16, and further changing the compressive capacity of the folding buffer assembly 10 to adapt to different items to be packaged or storage and transportation environments.

[0075] As Figure 4 shown, the present utility model further includes an embodiment of a packaging device 1. The packaging device 1 includes a box body 2 and the folding buffer assembly 10 as described in the foregoing embodiments. The box body 2 defines an accommodation space inside, which can accommodate the item to be packaged. The box body 2 can also be arranged to be made of folded paper material, as Figure 4 shown. The folding buffer assembly 10 can be arranged inside the box body 2 and is in contact with the inner side surface of the box body 2. Further, at least one of the folding buffer assembly 10 and the box body 2 is in contact with the inner side surface. Preferably, all the inner side surfaces of the box body 2 are in contact with one folding buffer assembly 10. The size of the folding buffer assembly 10 can be set to match the size of the inner side surface of the box body 2. When the side surface of the box body 2 is pressed, the folding buffer assembly 10 can absorb the deformation, avoiding the external pressure directly acting on the item to be packaged in the packaging device 1 and providing protection to the item to be packaged.

[0076] Finally, it should be noted that the above are only embodiments of the present utility model and are not used to limit the present utility model.
