Description

Technical Field

[0001] The utility model relates to the field of packaging articles, and particularly relates to a buffer structure and a packaging box. Background Art

[0002] A packaging box refers to a box used for packaging products. The packaging box can play a role in protecting products, improving the convenience of storage and transportation, and promoting sales during the circulation process of products.

During the process of taking the buffer structure, the product is displaced under the action of the adsorption force of the buffer structure, which is likely to cause the problem of product breakage.

Detailed Embodiments

[0045] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings.

[0046] With the development of technology and the continuous improvement of people's living standards, electronic products play an increasingly important role in our lives. As the carrier of electronic products, the packaging box plays an important role in protecting the product, transmitting information, and enhancing the product image. That is to say, the packaging box has the function of protecting electronic products and can effectively prevent electronic products from being damaged during transportation, storage, and sales. Usually, a buffer structure is provided inside the packaging box to reduce the impact force and vibration force transmitted to the product, thereby playing a role in protecting the product.

[0047] Please refer to Figure 1 , Figure 1It is a schematic structural diagram of a buffer structure 30 and a product 20. When a user needs to take out the product 20 from the packaging box, due to the long-term contact between the buffer structure 30 and the product 20, the adsorption force between the buffer structure 30 and the product 20 is relatively large. Exemplarily, the product 20 includes a display panel, and the position where the contact surface between the buffer structure 30 and the display panel is in a vacuum state, so that there is an adsorption force between the buffer structure 30 and the product 20. During the process of using the suction cup 40 to pick up the buffer structure 30, the product 20 will be displaced under the action of the adsorption force of the buffer structure 30, which is likely to cause the problem of damage to the product 20.

[0048] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , Figure 2 is a schematic structural diagram of a buffer structure 10 provided by an embodiment of the present invention. Figure 3 is Figure 2 a schematic cross-sectional structural diagram of the buffer structure 10 shown along the A1-A2 position. Figure 4 is a schematic structural diagram of another buffer structure 10 provided by an embodiment of the present invention. Figure 5 is Figure 4 a schematic cross-sectional structural diagram of the buffer structure 10 shown along the B1-B2 position. The buffer structure 10 may include a breathable layer 11, a first buffer layer 12, and a second buffer layer 13.

[0049] The breathable layer 11 has an opposite top surface 111 and bottom surface 112, and a side surface 113 connecting the top surface 111 and the bottom surface 112. The breathable layer 11 has a plurality of breathable channels, and the plurality of breathable channels are respectively communicated with the top surface 111, the bottom surface 112, and the side surface 113.

[0050] The first buffer layer 12 is connected to the bottom surface 112 of the breathable layer 11, the second buffer layer 13 is connected to the top surface 111 of the breathable layer 11, and at least one of the first buffer layer 12 and the second buffer layer 13 has a plurality of breathable holes k1. The breathable holes k1 penetrate through at least one buffer layer and are communicated with the breathable layer 11.

[0051] Exemplarily, as Figure 3 and Figure 6 shown, Figure 6FIG. 0 is a schematic structural diagram of a buffer structure 10 and a product 20 provided by an embodiment of the present invention. The product 20 may include a display panel. A plurality of ventilation holes k1 are provided in both the first buffer layer 12 and the second buffer layer 13. After the buffer structure 10 is attached to the display panel, since the side surface 113, the top surface 111, and the bottom surface 112 of the ventilation layer 11 can communicate with each other for ventilation, and the ventilation holes k1 in the first buffer layer 12 and the second buffer layer 13 communicate with the ventilation layer 11, it is possible to avoid a vacuum state at the position where the connection surface between the buffer structure 10 and the display panel is located, so that the pressure between the buffer structure 10 and the product 20 is kept consistent with the pressure in the external environment, thereby avoiding mutual adsorption between the buffer structure 10 and the display panel. In this way, the difficulty of removing the buffer structure 10 from the product 20 can be reduced, and damage to the product 20 caused by taking the buffer structure 10 can be avoided.

[0052] Exemplarily, as Figure 5 and Figure 7 shown, Figure 7 FIG. 9 is a schematic structural diagram of another buffer structure 10 and a product 20 provided by an embodiment of the present invention. A plurality of ventilation holes k1 are provided in the first buffer layer 12. After the buffer structure 10 is attached to the display panel, since the side surface 113 and the bottom surface 112 of the ventilation layer 11 can communicate with each other for ventilation, and the ventilation holes k1 in the first buffer layer 12 communicate with the ventilation layer 11, it is possible to avoid a vacuum state at the position where the connection surface between the buffer structure 10 and the display panel is located, so that the pressure between the buffer structure 10 and the product 20 is kept consistent with the pressure in the external environment, thereby avoiding mutual adsorption between the buffer structure 10 and the display panel. In this way, the difficulty of removing the buffer structure 10 from the product 20 can be reduced, and damage to the product 20 caused by taking the buffer structure 10 can be avoided.

[0053] In summary, a buffer structure provided by an embodiment of the present invention includes a ventilation layer, a first buffer layer, and a second buffer layer. At least one of the first buffer layer and the second buffer layer has a plurality of ventilation holes, and a ventilation layer is provided between the first buffer layer and the second buffer layer. After the buffer structure is attached to the product, since the ventilation layer can communicate with the ventilation holes for ventilation, it is possible to avoid a vacuum state at the position where the connection surface between the buffer structure and the product is located, so that the pressure between the buffer structure and the product is kept consistent with the pressure in the external environment, thereby avoiding mutual adsorption between the buffer structure and the display panel. In this way, damage to the product caused by taking the buffer structure can be avoided, and the difficulty of removing the buffer structure from the product can be reduced.

[0054] Please refer to Figure 8 , Figure 8FIG. 0 is a schematic structural view of another buffer structure 10 provided by an embodiment of the present invention. In an alternative embodiment, the first buffer layer 12 may have a plurality of first ventilation holes k11, and the first ventilation holes k11 penetrate through the first buffer layer 12. The second buffer layer 13 may have a plurality of second ventilation holes k12, and the second ventilation holes k12 penetrate through the second buffer layer 13. By providing ventilation holes k1 on both the first buffer layer 12 and the second buffer layer 13, the air permeability of the buffer structure 10 can be improved.

[0055] Please refer to Figure 9 , Figure 9 FIG. 7 is a schematic structural view of another buffer structure 10 and a product 20 provided by an embodiment of the present invention. In an exemplary embodiment, a plurality of buffer structures 10 and a plurality of products 20 may be stacked in a direction perpendicular to the ground. In this case, both sides of the buffer structure 10 are in contact with the product 20. Since both the first buffer layer 12 and the second buffer layer 13 in the buffer structure 10 have ventilation holes k1, it is possible to prevent the buffer structure 10 from being adsorbed to the products 20 located on both sides of the buffer structure 10.

[0056] Please refer to Figure 8 and Figure 9 , in an alternative embodiment, the first ventilation holes k11 and the second ventilation holes k12 are offset in a direction perpendicular to the top surface 111 of the ventilation layer 11. Compared with the scheme in which the first ventilation holes k11 and the second ventilation holes k12 coincide in a direction perpendicular to the top surface 111 of the ventilation layer 11, offsetting the first ventilation holes k11 and the second ventilation holes k12 can improve the overall strength of the buffer structure 10.

[0057] Please refer to Figure 8 , in an alternative embodiment, both the first buffer layer 12 and the second buffer layer 13 may include a support layer 121 and an antistatic layer 122. The support layer 121 is connected to the top surface 111 or the bottom surface 112 of the ventilation layer 11, and the antistatic layer 122 is connected to the side of the support layer 121 facing away from the ventilation layer 11. The thickness of the antistatic layer 122 may be less than the thickness of the support layer 121. The flexural strength of the support layer 121 is greater than the flexural strength of the ventilation layer 11. The flexural strength refers to the maximum stress that a material can withstand when it breaks or reaches a specified bending moment under a bending load. The flexural strength can reflect the ability of the material to resist bending, and the flexural strength can also be called the flexural strength.

[0058] It should be noted that in the embodiment of the present invention, taking the first buffer layer 12 including the support layer 121 and the antistatic layer 122 as an example for illustration, the structure of the second buffer layer 13 is the same as or similar to the structure of the first buffer layer 12, and the embodiment of the present invention will not repeat it here.

[0059] In the related art, during the transportation of product 20, mutual friction between the buffer structure 30 and product 20 causes redistribution of charges, and static electricity is formed between the buffer structure 30 and product 20. Due to the electrostatic induction between the buffer structure 30 and product 20, there is an electrostatic adsorption phenomenon between the buffer structure 30 and product 20, thereby increasing the difficulty of separating the buffer structure 30 and product 20.

[0060] In an embodiment of the present utility model, by providing an antistatic layer 122 on the side of the support layer 121 facing away from the breathable layer 11, that is, by providing an antistatic layer 122 on the side of the support layer 121 close to product 20, it is possible to reduce or prevent the accumulation of charges on the contact surface between the buffer structure 10 and product 20. That is, the antistatic layer 122 can absorb or conduct static electricity, thereby effectively reducing the static charges on the surface of the buffer structure 10. In this way, it is possible to solve the problems of product 20 breakage and downtime caused by electrostatic adsorption of the underlying product 20 when removing the buffer material on the upper layer of product 20, and can reduce the difficulty of removing the buffer structure 10 from product 20. At the same time, it can also avoid the problem of poor electrostatic discharge (abbreviation: ESD) of product 20 caused by the static electricity on the buffer structure 10.

[0061] In an exemplary embodiment, the material of the support layer 121 may include a foaming material, such as at least one of Ethylene Vinyl Acetate Copolymer (abbreviation: EVA), Irradiated cross-linked polyethylene foam (abbreviation: IXPE), Expandable Polyethylene (abbreviation: EPE), and polypropylene (abbreviation: PP). The foaming ratio of the foaming material may range from 20 times to 50 times. Exemplarily, the foaming ratio of the luminescent material is 50 times, 40 times, 30 times, 25 times, or 20 times.

[0062] In an exemplary embodiment, the material of the breathable layer 11 may include sponge to ensure that outside air passes through the breathable layer 11 and reaches between product 20 and the buffer structure 10 along the breathable holes k1.

[0063] Please refer to Figure 10 , Figure 101 is a schematic diagram of the structure of another buffer structure 10 provided by an embodiment of the utility model. In an optional implementation, the antistatic layer 122 may include a substrate base layer 1221 and an antistatic film layer 1222. The substrate base layer 1221 is connected to the side of the support layer 121 away from the breathable layer 11, and the antistatic film layer 1222 is connected to the side of the substrate base layer 1221 away from the support layer 121. The substrate base layer 1221 can be used to connect the support layer 121 and the antistatic film layer 1222 to improve the film quality of the antistatic film layer 1222.

[0064] The material of the antistatic film layer 1222 includes an antistatic agent, which refers to a material that is mixed with a small amount of chemical substances in an insulating material to increase the conductivity and hydrophilicity of the material, reduce the volume resistance and surface resistance, promote charge leakage, and eliminate the harm of static electricity.

[0065] Please refer to the figure Figure 10 and Figure 11 , Figure 11 It is a structural schematic diagram of an antistatic layer 122 provided in an embodiment of the utility model. In an optional implementation, the antistatic film layer 1222 may include an antistatic sustained-release layer c1 and an antistatic coating c2; the antistatic sustained-release layer c1 is connected to the side of the substrate base layer 1221 away from the breathable layer 11, and the antistatic coating c2 is connected to the side of the antistatic sustained-release layer c1 away from the substrate base layer 1221.

[0066] The antistatic slow-release layer c1 can delay the release process of the antistatic material in the antistatic agent to prolong the antistatic effect of the antistatic film layer 1222. The antistatic slow-release layer c1 can be composed of an antistatic active ingredient and an antistatic slow-release carrier material, wherein the antistatic slow-release carrier material plays the role of carrying the antistatic active ingredient and slowly releasing the antistatic active ingredient.

[0067] The material of the antistatic coating c2 may include a mixed liquid coating, which may include a mixture of at least one of resin or isopropyl alcohol and a polymer antistatic agent. Exemplarily, the polymer antistatic agent may include at least one of polythiophene (English: Polythiophene), polyacetylene (English: polyacetylene) and polyaniline (English: polyaniline).

[0068] In the related art, the antistatic function is achieved by covering the outer surface of the buffer structure 30 with an antistatic coating. For example, the antistatic agent is attached to the surface of the buffer structure 30 by coating, spraying, dipping, etc., and the antistatic coating can be formed after the antistatic agent is dried. However, during the process, the antistatic agent falls off after being subjected to force or friction, resulting in poor durability of the antistatic coating.

[0069] In the embodiment of the present utility model, an antistatic slow-release layer c1 is added on the side of the antistatic coating c2 close to the substrate base layer 1221. The antistatic slow-release layer c1 can play a role in controlling the release of the antistatic material, which can improve the antistatic durability of the buffer structure 10. In this way, when removing the buffer material on the upper layer of the product 20, the problem of product 20 breakage and downtime caused by electrostatic adsorption of the lower product 20 can be solved, the difficulty of removing the buffer structure 10 from the product 20 can be reduced, and at the same time, the problem of poor electrostatic discharge (abbreviation: ESD) of the product 20 caused by the static electricity on the buffer structure 10 can be avoided.

[0070] Please refer to Figure 12 , Figure 12 FIG. is a schematic structural diagram of an antistatic slow-release layer c1 provided by an embodiment of the present utility model. In an optional embodiment, the antistatic slow-release layer c1 may include a dielectric layer c11, a capsule shell c12, and a capsule core material c13 made of an antistatic agent; the capsule shell c12 is distributed in the dielectric layer c11, and the capsule core material c13 is located in the capsule shell c12. The capsule shell c12 may be evenly distributed in the dielectric layer c11. The capsule structure formed by the capsule shell c12 and the capsule core material c13 in the antistatic slow-release layer c1 can play a role in controlling the release rate of the antistatic material, which can improve the antistatic durability of the buffer structure 10.

[0071] Exemplarily, the antistatic agent may include surfactant-type antistatic agents, such as primary amine salts and hydroxy salts. The capsule shell c12 may also be referred to as a capsule wall material, and the material of the capsule shell c12 may include polymer materials, such as at least one of polyethylene (abbreviation: PE), polystyrene (abbreviation: PS), polypropylene, and polyamide (abbreviation: PA). The dielectric layer c11 may include a resin.

[0072] In addition, during the use of the buffer structure 10, if there is static electricity on the surface of the buffer structure 10, it will cause dust to accumulate on the surface of the buffer structure 10 more easily, thus affecting the user experience. In the embodiment of the present utility model, by providing an antistatic layer 122 on the surface of the buffer structure 10, the accumulation of charges on the surface of the buffer structure 10 during the use of the buffer structure 10 can be avoided, thereby improving the surface cleanliness of the buffer structure 10 and enhancing the user experience.

[0073] In an alternative embodiment, the substrate base layer 1221 may include a single-layer film layer made of plastic. Exemplarily, the material of the single-layer film layer may include polyethylene, polypropylene, or polyethylene glycol terephthalate (PET for short).

[0074] Alternatively, the substrate base layer 1221 may include a stacked multi-layer film layer, and the multi-layer film layer includes at least one single-layer film layer made of plastic and at least one single-layer film layer made of metal. Exemplarily, the multi-layer film layer may be one of composite film layers such as PET / AL (aluminum) / PE, PA / AL / PE, etc.

[0075] Alternatively, the substrate base layer 1221 may include a composite film layer: CPP (cast polypropylene) / PET.

[0076] Please refer to Figure 13 , Figure 13 which is a schematic structural diagram of another buffer structure 10 provided by an embodiment of the present invention. In an alternative embodiment, a plurality of ventilation holes k1 in the same buffer layer may be arranged in rows and columns; a first distance between the centers of any two adjacent ventilation holes k1 in the row direction may be equal, a second distance between the centers of any two adjacent ventilation holes k1 in the column direction may be equal, and the first distance and the second distance may be equal. In this way, the uniformity of the strength at different positions of the buffer structure 10 can be improved, and the overall strength of the buffer structure 10 can be improved.

[0077] Please refer to Figure 13 and Figure 14 , Figure 14 which is a schematic structural diagram of another buffer structure 10 and a product 20 provided by an embodiment of the present invention. In an alternative embodiment, a plurality of ventilation holes k1 may satisfy the following formula:

[0078]

[0079] wherein, R is the radius of the ventilation hole k1, F1 is the weight of the buffer structure 10 or the weight of the product 20, the product 20 and the buffer structure 10 are stacked in a direction perpendicular to the ground, F is the force between the buffer structure 10 and the product 20 when there is no ventilation hole k1 in the buffer structure 10, and L is the first distance or the second distance. When the buffer structure 10 is on the side of the product 20 away from the ground, F1 is the weight of the buffer structure 10, and when the buffer structure 10 is on the side of the product 20 close to the ground, F1 is the weight of the product 20. When the radius of the ventilation hole k1 is within this range, while ensuring the breathability of the buffer structure 10, the strength of the buffer structure 10 can be better. As Figure 14As shown, the buffer structure 20 and the product can be separated by the suction cup 40.

[0080] In summary, a buffer structure provided by an embodiment of the present invention includes a breathable layer, a first buffer layer, and a second buffer layer. At least one of the first buffer layer and the second buffer layer has a plurality of breathable holes, and a breathable layer is provided between the first buffer layer and the second buffer layer. When the buffer structure is attached to the product, since the breathable layer can communicate with the breathable holes for ventilation, it is possible to avoid a vacuum state at the position where the connection surface of the buffer structure and the product is located, so that the pressure between the buffer structure and the product is consistent with the pressure in the external environment, thereby avoiding mutual adsorption between the buffer structure and the display panel. In this way, it is possible to avoid damage to the product caused by taking the buffer structure, and the difficulty of removing the buffer structure from the product can be reduced.

[0081] In addition, an embodiment of the present invention further provides a packaging box, which may include a housing and a buffer structure. The housing has an accommodation space, and the buffer structure is located in the accommodation space. The buffer structure can be the buffer structure in any of the above embodiments.
