Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a composite cushioning packaging structure, a packaging set provided with the composite cushioning packaging structure, and a packaging product using the packaging set. Background Art

[0002] Most products are packaged for sale, whether for protection during transportation and / or handling, or to enhance the aesthetics of the product when sold. Currently, there are two main ways to package products:

[0003] The first type is that the number of packaged products is one;

[0004] The second type is that there are multiple packaged products, and the multiple packaged products are vertically stacked and packaged in a box; or the multiple packaged products are distributed in a horizontal rectangular array and packaged in a box; or the multiple packaged products are first divided into two or more packaging groups, each packaging group includes two or more packaged products distributed in a horizontal rectangular array, and then the two or more packaging groups are vertically stacked and packaged in the same box.

[0005] However, whether it is packaging a single product or multiple products, foam is often used as a cushioning packaging material to support, cushion and protect the product, especially for electrical products. However, the use of foam as a cushioning packaging material has the following disadvantages:

[0006] First, when making foam, a mold needs to be made, which results in a high cost.

[0007] Second, after the foam is formed, its structure is fixed and unchanged, and the foam occupies a large space, which is not conducive to storage and transportation, and is not conducive to environmental protection.

[0008] Third, since the foaming foam takes up a large space, it seriously occupies the internal space of the packaging box, especially when the number of packaged products is large, the internal space of the packaging box is larger; and the packaged products formed after packaging also have the problem of large volume, which is not conducive to the storage and transportation of the packaged products and increases costs. Summary of the Invention

[0009] The main purpose of the utility model is to provide a composite cushioning packaging structure which has good protection effect, occupies little space and is convenient for storage and transportation.

[0010] Another object of the present invention is to provide a packaging set provided with the composite cushioning packaging structure.

[0011] Another object of the present invention is to provide a packaging product provided with the above packaging set.

[0012] In order to achieve the main purpose of the present invention, the present invention provides a composite cushioning packaging structure, which includes a cushioning body, the cushioning body includes a paper card and at least one cushioning pad, the paper card is bent and arranged to form a right prism, the right prism has a hollow portion that penetrates itself along its own axis, the cushioning pad is located in the hollow portion and extends axially, and a cushioning pad is installed on a side wall of the right prism.

[0013] As can be seen from the above, the structure of the bent paper card itself has a certain degree of cushioning and supporting capacity. Based on this, the cushioning pad provided in the hollow part can effectively support and cushion the packaged products placed in the hollow part, preventing the packaged products from being damaged during storage and transportation; and compared with simply using foam to cushion and support the packaged objects, the composite structure of paper card and cushioning pad can occupy a smaller space while ensuring at least equivalent cushioning and support for the packaged products, which is conducive to improving space utilization, so that more packaged products can be packaged in the same space, or the space occupied by the packaged products after packaging can be reduced, which is more conducive to the storage and transportation of packaged products; at the same time, since paper card has the ability to fold, it is also more convenient for storage and transportation than foam.

[0014] A further solution is that the composite cushioning packaging structure also includes an end paper card, which has a support plate portion and a support side portion. The support plate portion is polygonal, and the number of sides of the polygon is equal to the number of edges of the right prism. The support side portion is connected to at least a portion of the sides of the polygon, and the support side portion can be bent relative to the support plate portion. The end paper card is inserted into the hollow portion, and the support side portion can contact the oppositely arranged cushioning pad or side wall.

[0015] As can be seen from the above, the end paper card is used to prevent the packaged product from moving in the axial direction of the buffer body, and the end paper card is easy to store and transport due to its foldable function; in addition, while achieving the same limiting function, the end paper card has a greater price advantage than the foam, and the end paper card can be recycled, which improves the environmental friendliness of the composite buffer packaging structure.

[0016] A further solution is that the composite cushioning packaging structure further includes at least one cushioning block, which can be placed between two adjacent packaged products.

[0017] As can be seen from the above, when the number of packaged products is more than two, placing a buffer pad between two adjacent packaged products can prevent the two adjacent packaged products from colliding with each other, thereby preventing the packaged products from being damaged during storage and transportation; and the buffer pad is also beneficial for reducing the gap between two adjacent packaged products and improving space utilization.

[0018] A further solution is that the composite cushioning packaging structure further includes a cushioning bottom pad, in the axial direction, the end paper card is located at the first end of the cushioning body, and the cushioning bottom pad is arranged at the second end of the cushioning body.

[0019] As can be seen from the above, the cushioning base pad has a stronger pressure-bearing capacity than paper card-type cushioning supports and can carry heavier packaged products (groups); therefore, using the cushioning base pad and placing it at the very bottom of the packaged products (groups) can better cushion and support the packaged products (groups), while ensuring that the packaged products (groups) obtain good cushioning and support effects, thereby maximizing the cushioning and support effects of the composite cushioning packaging structure and minimizing the space required.

[0020] A further solution is that the number of edges of the right prism is between 3 and 12; the paper card is provided with two or more first fold lines on the inner side of the side wall, the two or more first fold lines are distributed along the length direction of the paper card, the first fold lines are distributed along the axial direction, one first fold line corresponds to one edge of the right prism, and the length direction is perpendicular to the axial direction; in the length direction, the first end of the paper card has a joint portion, the joint portion is used to connect with the second end of the paper card, and the joint portion can be bent along the edge corresponding to the first end of the paper card; the joint portion is adhesively fixed to the second end of the paper card, or the joint portion and the second end of the paper card are fixed by staples.

[0021] As can be seen from the above, setting the first fold line on the paper card makes it more convenient and easy to operate when bending the paper card into a right prism, and can ensure that the shape of the right prism is more accurately formed according to the set requirements; the joint makes the connection between the head and tail ends of the bent right prism more convenient and secure.

[0022] A further solution is that the number of edges of the right prism is an even number; the number of buffer plates is half of the number of edges of the right prism, the buffer plates are evenly distributed along the circumference of the right prism, and a force unloading groove is formed between two adjacent buffer plates; along the edge corresponding to the side wall where the buffer plate is located, there is a non-zero spacing between the buffer plate and the edge corresponding to the side wall.

[0023] As can be seen from the above, setting the number of edges of the right prism to an even number allows the right prism to have more side walls that fit adjacent to the inner walls of a conventional packaging box (a rectangular parallelepiped, including a cube), thereby improving the stability of the buffer body placed in the packaging box and ensuring the buffering and supporting effect of the buffer body on the packaged products; based on this, by setting the number of buffer pads to half the number of edges of the right prism, the structure of the buffer body is optimized while ensuring that the buffering and support requirements are met, and at the same time, the force unloading groove formed is used to disperse the unidirectional force of the packaged products during storage and transportation, thereby improving the buffering performance of the buffer body.

[0024] A further solution is that a supporting side portion is provided on each edge of the support plate portion, and a second fold line is provided at the position where the end paper is stuck at the edge of the support plate portion; the support plate portion is provided with an assembly hole that penetrates itself axially; the edge of the support plate portion can contact the relatively arranged buffer pad; in the axial direction, the first end of the buffer pad block is provided with a first avoidance groove, the first avoidance groove is recessed from the first end of the buffer pad block to the inside of the buffer pad block, and the second end of the buffer pad block is provided with a second avoidance groove, the second avoidance groove is recessed from the second end of the buffer pad block to the inside of the buffer pad block; the buffer base pad is provided with a accommodating slot on a side facing the buffer body, the accommodating slot is recessed from the side of the buffer base pad facing the buffer body to the inside of the buffer base pad in the axial direction, and the accommodating slot is connected to the hollow portion.

[0025] As can be seen from the above, a supporting side portion is provided on each edge of the support plate portion, which can better improve the strength of the support plate portion and improve the reliability of the connection between the end paper card and the buffer body. At the same time, it also makes it unnecessary to identify the installation direction when assembling the end paper card and the buffer body, making the assembly of the end paper card more convenient. The setting of the second fold line makes it more convenient and easy to operate when bending the supporting side portion relative to the support plate portion, and the bending position can be more accurately formed according to the set position.

[0026] A further solution is that the number of right prisms is 8; the paper card is made of cardboard or corrugated paper; the end paper card is made of cardboard or corrugated paper; the buffer pad is made of EPE, EVA, EPP or foam; the buffer pad block is made of EPE, EVA, EPP or foam; and the buffer base is made of EPE, EVA, EPP or foam.

[0027] As can be seen from the above, setting the number of right prisms to 8 can optimize the structure of the buffer body, so that under the condition of the same packaged product, the number of contact surfaces between the right prisms and the conventional packaging box is maximized, and the buffering effect of the buffer body is optimized, and it is more conducive to minimizing the volume of the conventional packaging box, thereby maximizing the use of the internal space of the conventional packaging box; cardboard or corrugated paper is used to make paper cards and end paper cards, which can have the strength that meets the use requirements, and are easy to produce, process, recycle, bend, form, and store and transport; and EPE, EVA, EPP or foamed foam is used to make buffer pads, buffer blocks and buffer bottom pads, all of which can have excellent buffering and supporting properties.

[0028] In order to achieve another purpose of the utility model, the utility model provides a packaging set, including a packaging box, the packaging box having a accommodating cavity, wherein the packaging set also includes the above-mentioned composite cushioning packaging structure; the cushioning bottom pad is arranged between the bottom of the accommodating cavity and the cushioning body, and the cushioning body is arranged in the accommodating cavity and adjacent to the cavity wall of the accommodating cavity.

[0029] As can be seen from the above, the packaging set provided with the above-mentioned composite cushioning packaging structure can better utilize the space of the accommodating cavity to accommodate and package more packaged products in the same space; and through the design of the composite cushioning packaging structure, the packaging set is more convenient during storage and transportation.

[0030] In order to achieve another purpose of the present invention, the present invention provides a packaging product, including at least one packaged product, wherein the packaging product also includes the above-mentioned packaging set, and the packaged product is placed in the hollow part and adjacent to the buffer pad; when the number of packaged products is one, in the axial direction, the packaged product is installed between the buffer bottom pad and the end paper card; when the number of packaged products is two or more, the two or more packaged products are distributed along the axial direction, and a buffer pad is provided between two adjacent packaged products, and in the axial direction, the packaged product located at the bottom is cooperated and connected with the buffer bottom pad, and the packaged product located at the top is cooperated and connected with the end paper card.

[0031] As can be seen from the above, by setting the above packaging structure, the packaging product can be easily stored and transported before packaging; the packaged product formed after packaging the same number of packaged products takes up less space, is more convenient for storage and transportation, and has lower packaging costs.

[0043] Packaging product examples

[0044] Reference Figure 1 The packaging product 100 includes a packaging set 101 and a packaged product 102. The packaging set 101 is used to package the packaged product 102 and provide cushioning and support for the packaged product 102, preventing damage to the packaged product 102 during storage and transportation. The packaging set 101 includes a composite cushioning packaging structure 1011 and a packaging box 1012. The packaged product 102 can be a lamp, a speaker, a disc, or a stepped shaft. The packaging box 1012 can be a conventional packaging box 1012 (such as a rectangular parallelepiped, including a cube) or an unconventional packaging box 1012 (such as a right prism). Therefore, each of these types of packaging boxes will not be described here. In this embodiment, the packaging product 100 will be described below using the example of a lamp as the packaged product 102 and a conventional packaging box 1012 as the packaging box, but this does not limit the inventive concept of the packaging product 100.

[0045] Combine Figure 2 The composite cushioning packaging structure 1011 includes a cushioning body 1, an end paper card 2, a cushioning pad 3 and a cushioning bottom pad 4. Figure 3 and Figure 4 The buffer body 1 includes a paper card 11 and at least one buffer pad 12, wherein the paper card 11 can be bent to form a straight prism (such as Figure 4 As shown), the middle part of the right prism has a hollow portion 112 that passes through the right prism along the axial direction of the right prism; the buffer plate 12 is located in the hollow portion 112, the buffer plate 12 extends along the axial direction of the right prism, and one buffer plate 12 is installed on a side wall of the right prism.

[0046] Preferably, the number of edges of the right prism is between 3 and 12, allowing the cushioning body 1 to be adapted to a variety of different usage scenarios, thereby enhancing the practicality and applicability of the cushioning body 1. Preferably, the number of edges of the right prism is even, and the number of cushioning plates 12 is half the number of edges of the right prism. Furthermore, two or more cushioning plates 12 are evenly distributed along the circumference of the right prism, forming a force-releasing groove 113 between adjacent cushioning plates 12. The number of edges of the right prism is set to an even number, so that the right prism can have at least two or more side walls that are in contact with the inner wall of the conventional packaging box 1012, thereby improving the stability of the buffer body 1 placed in the packaging box 1012 and ensuring the buffering and supporting effect of the buffer body 1 on the packaged product 102; and based on this, by setting the number of buffer pads 12 to half the number of edges of the right prism, the structure of the buffer body 1 is optimized while ensuring that the buffering and supporting requirements are met, and at the same time, the unloading groove 113 formed is used to disperse the unidirectional force of the packaged product 102 during storage and transportation, thereby improving the buffering performance of the buffer body 1. In addition, the number of buffer pads 12 is also conducive to reducing the storage and transportation space of the buffer body 1 (see the description below).

[0047] More preferably, as in this embodiment, the number of edges of the right prism is 8. Setting the number of edges of the right prism to 8 enables the buffer body 1 to have the following better effects:

[0048] First, the buffering effect of the buffer body 1 is optimized. Since the number of edges of the right prism is 8, the buffer body 1 has four side walls that do not fit the inner wall of the conventional packaging box 1012. Therefore, the buffer body 1 has a certain deformation space to cooperate with the buffer pad 12 and the force unloading groove 113 to disperse the force of the packaged product 102 in the front, back, left and right directions of the conventional packaging box 1012, thereby improving the buffering protection effect of the packaged product 102, and also ensuring that the buffer body 1 can reliably support the packaged product 102.

[0049] Second, based on the first point mentioned above, the structure of the buffer body 1 is optimized so that under the condition of the same packaged product 102 (based on the right prism with the aforementioned different numbers of edges), the number of contact surfaces between the buffer body 1 and the conventional packaging box 1012 is maximized, and the contact area is reasonable, so as to better prevent the buffer body 1 from moving in the conventional packaging box 1012.

[0050] Third, based on the second point mentioned above, it is more conducive to minimizing the volume of the conventional packaging box 1012, thereby maximizing the use of the internal space of the conventional packaging box 1012; for example, when the number of edges of the right prism is 6 or 10, the required size of the conventional packaging box 1012 is larger than when the number of edges of the right prism is 8, and when the number of edges of the right prism is 12, the contact area between the buffer body 1 and the conventional packaging box 1012 is smaller than the contact area when the number of edges of the right prism is 8.

[0051] In order to facilitate the folding storage and transportation of the buffer body 1 (such as Figure 5 as shown) or stacked storage in the unfolded state (as shown Figure 6 As shown), along the edge corresponding to the side wall of the right prism where the buffer pad 12 is located, there is a non-zero spacing W between the buffer pad 12 and the edge corresponding to the side wall, so as to cushion the folding storage or stacking storage of the main body 1; preferably, the buffer pad 12 is centered with the side wall where it is located.

[0052] like Figure 3 As shown, the paper card 11 preferably has two or more first fold lines 110 on the inner side of the side wall. The two or more first fold lines 110 are distributed along the length of the paper card 11, and the first fold lines 110 are distributed along the axial direction, with each first fold line 110 corresponding to an edge of the right prism; wherein the length direction is perpendicular to the axial direction. In addition, along the length direction of the paper card 11, the first end of the paper card 11 has a joint 111. The joint 111 can be bent along the edge corresponding to the first end of the paper card 11. The provision of the joint 111 makes the connection between the end and the end of the right prism more convenient and secure. Furthermore, the edge is preferably also provided with a first fold line 110 to facilitate precise bending of the joint 111, making bending more convenient and easier. Similarly, the provision of the first fold line 110 also makes bending the paper card 11 into the right prism more convenient and easier to operate, and can ensure that the shape of the right prism is more accurately formed according to the set requirements.

[0053] When the joint portion 111 is connected to the second end of the paper card 11, as an optional connection method, the joint portion 111 and the second end of the paper card 11 can be bonded and fixed by an adhesive. The advantage of this fixing method is that it is convenient for the user to bend the paper card 11 when packaging the packaged product 102, thereby making it easier to store and transport the buffer body 1, and better maintaining the shape of the buffer body 1, avoiding unnecessary creases on the paper card 11 (such as Figure 6As shown). Of course, as another optional method, the engageable portion 111 and the second end of the paper card 11 can also be fixed by a staple; this fixing method allows the user to directly purchase the buffer body 1 that has been bent into a straight prism, and the buffer body 1 that has been bent into a straight prism can also be folded into the shape of the buffer body 1 by performing appropriate secondary bending on the paper card 11 during storage and transportation. Figure 5 The paper card 11 is stored and transported in the plate shape shown, and the buffer body 1 is reopened into a straight prism shape during the packaging process, so that the user does not need to bend the paper card 11, fix the ends and other processes during the packaging process, which is conducive to saving packaging time and improving packaging efficiency; however, this processing method will more or less cause the paper card 11 to be reopened into a straight prism shape, thereby affecting the structural stability of the buffer body 1, and further affecting the buffering and supporting effects of the buffer body 1. However, no matter which of the above connection methods is used, when the buffer bodies 1 are stacked for storage and transportation, the buffer pad 12 of one unfolded buffer body 1 can be placed in the gap between two adjacent buffer pads 12 of another unfolded buffer body 1 (such as Figure 6 When the buffer body 1 is folded for storage and transportation, the buffer pad 12 of the folded buffer body 1 can be placed in the gap between the other two adjacent buffer pads 12 (as shown); Figure 5 As shown); it can be seen that the above two connection methods can reduce the space occupied by the buffer body 1 during storage and transportation.

[0054] Combine Figure 7 The end paper card 2 has a support plate portion 21 and support side portions 22. The support plate portion 21 is polygonal in shape, with the same number of sides as the right prism formed by the paper card 11, so that the outline of the polygon resembles the outline of the bottom surface of the right prism. In addition, the support side portions 22 are connected to at least a portion of the sides of the polygon, and the support side portions 22 can be bent relative to the support plate portion 21. When the end paper card 2 is assembled with the buffer body 1, the end paper card 2 is inserted into the hollow portion 112, and the support side portions 22 primarily contact the oppositely disposed buffer pad 12. Of course, the support side portions 22 may also contact the oppositely disposed side walls.

[0055] The support plate 21 is used to support, cushion, and position the packaged product 102, while the support side 22 can enhance the strength of the support plate 21 and the reliability and stability of the connection between the end paper card 2 and the buffer body 1. It can be seen that the end paper card 2 is used to prevent the packaged product 102 from axially shifting in the buffer body 1, and the end paper card 2 is foldable, making it convenient for storage and transportation. In addition, when achieving the same limiting function, the end paper card 2 is more cost-effective than foaming foam, and the end paper card 2 can be recycled, improving the environmental friendliness of the composite cushioning packaging structure 1011.

[0056] Preferably, each side of the support plate 21 is provided with a supporting side portion 22 to further enhance the strength of the support plate 21 and improve the reliability of the connection between the end paper card 2 and the buffer body 1. This also eliminates the need to identify the installation direction when assembling the end paper card 2 with the buffer body 1, making assembly of the end paper card 2 more convenient. To facilitate and operate the bending of the supporting side portion 22 relative to the support plate 21 and to more accurately form the bending position between the supporting side portion 22 and the support plate 21 according to the set position, a second fold line 20 is provided at the edge of the end paper card 2 at the edge of the support plate 21. Preferably, the size of the support plate 21 is configured so that when the end paper card 2 is assembled with the buffer body 1, the edge of the support plate 21 can contact the oppositely disposed buffer pad 12, thereby ensuring that the support plate 21 provides cushioning, support, and position-limiting effects on the packaged product 102.

[0057] In addition, an assembly hole 211 can be provided on the support plate portion 21, and the assembly hole 211 can pass through the support plate portion 21 in the axial direction of the right prism; when the end paper card 2 cooperates with the buffer body 1 to package the packaged product 102, the end paper card 2 can be sleeved on the packaged product 102 through the assembly hole 211 to better cushion, support and limit the packaged product 102. At the same time, it is also beneficial to reduce the volume of the packaging box 1012, and then reduce the volume of the packaged product 100, so as to be more conducive to the storage and transportation of the packaged product 100.

[0058] It should be noted that, as in this embodiment, in the axial direction of the right prism, the two ends of the buffer plate 12 are preferably flush with the two ends of the right prism; and as another optional solution, the end of the buffer plate 12 close to the end paper card 2 can be kept at a distance from the end of the right prism close to the end paper card 2, and the distance is equal to the end paper card 2 after bending (such as Figure 1 and Figure 2 As shown in the figure, the end of the end paper card 2 is flush with the end of the buffer body 1, so as to ensure the buffering and supporting effect of the composite buffer packaging structure 1011 on the packaged product 102; at this time, the supporting side portions 22 of the end paper card 2 are in contact with the inner wall surface of the right prism.

[0059] Furthermore, the paper card 11 is preferably made of cardboard or corrugated paper, so that it can have the strength that meets the use requirements, and is easy to produce, process, recycle, and bend, form, and store and transport; similarly, the end paper card 2 is preferably made of cardboard or corrugated paper, so that it can have the strength that meets the use requirements, and is easy to produce, process, recycle, and bend, form, and store and transport.

[0060] Combine Figure 8 and Figure 9When the number of packaged products 102 is more than two, the buffer pad 3 can be placed between two adjacent packaged products 102 to prevent the two adjacent packaged products 102 from colliding with each other, thereby preventing the packaged products 102 from being damaged during storage and transportation; and when the packaged products 102 are products such as lamps and speakers, compared with using a whole piece of foam board to be placed between two adjacent packaged products 102, the buffer pad 3 can provide fixed support for specific parts of the two adjacent packaged products 102, so that the buffer pad 3 can have a smaller volume and higher strength to prevent pressure cracking, and by directly placing the buffer pad 3 between two adjacent packaged products 102, products such as lamps and speakers can also have a certain overlapping area in the stacking direction (i.e., the axial direction of the right prism), which is conducive to better reducing the gap between the two adjacent packaged products 102 and improving the utilization rate of the space in the packaging box 1012.

[0061] Preferably, in the axial direction of the right prism, a first relief groove 31 is provided at the first end of the buffer block 3, the first relief groove 31 being recessed from the first end of the buffer block 3 into the interior of the buffer block 3. A second relief groove 32 is provided at the second end of the buffer block 3, the second relief groove 32 being recessed from the second end of the buffer block 3 into the interior of the buffer block 3. The first relief groove 31 and the second relief groove 32 can avoid certain relatively protruding portions of the packaged products 102, thereby preventing the overall stacking height of the multiple packaged products 102 from increasing. They can also improve the stability of the buffer block 3 when placed between two adjacent packaged products 102, thereby preventing the buffer block 3 from falling out of the space between the two adjacent packaged products 102. It should be noted that the number of buffer blocks 3 is determined by the number of packaged products 102. When there is only one packaged product 102, no buffer block 3 is required. When there are two or more packaged products 102, the number of buffer blocks 3 can be one less than the number of packaged products 102.

[0062] Combine Figure 10In the axial direction of the right prism, the end paper card 2 is located at the first end of the buffer body 1, and the buffer base pad 4 is provided at the second end of the buffer body 1. Compared to paper card-type buffer supports, the buffer base pad 4 has a stronger pressure-bearing capacity and can carry heavier packaged products 102 (or groups of packaged products, where the group 2 of packaged products refers to a collection of two or more packaged products 102). Therefore, using the buffer base pad 4 and placing it at the very bottom of the packaged product 102 (or group of packaged products) can better cushion and support the packaged product 102 (or group of packaged products), ensuring that the packaged product 102 (or group of packaged products) obtains good cushioning and support effects, thereby maximizing the cushioning and support effects of the composite cushioning packaging structure 1011 and minimizing the required space. The cushioning bottom pad 4 cooperates with the cushioning body 1 and the end paper card 2 to increase the overall compressive strength of the composite cushioning packaging structure 1011 and the packaged product 102 (or packaged product group) in the upper and lower directions of the packaging box 1012.

[0063] Furthermore, a receiving slot 41 is provided on the side of the cushioning base 4 facing the cushioning body 1. The receiving slot 41 is recessed into the cushioning base 4 in the axial direction of the right prism, extending from the side of the cushioning base 4 facing the cushioning body 1. The receiving slot 41 communicates with the hollow portion 112. The receiving slot 41 accommodates and positions the packaged product 102 at the bottom, thereby improving the stability of the packaged product 102 (or group of packaged products) within the hollow portion 112 of the cushioning body 1 and reducing the possibility of the packaged product 102 (or group of packaged products) moving within the hollow portion 112.

[0064] In this embodiment, the cushioning plate 12, cushioning block 3, and cushioning base 4 are preferably all made of EPE (Electronic Polyethylene Foam), ensuring that the cushioning plate 12, cushioning block 3, and cushioning base 4 all provide excellent cushioning and support performance. Alternatively, the cushioning plate 12 may be made of EVA (Ethylene Vinyl Acetate Copolymer), EPP (Highly Expanded Polypropylene), or foam. Similarly, the cushioning block 3 may be made of EPE, EVA, EPP, or foam, and the cushioning base 4 may be made of EPE, EVA, EPP, or foam.

[0065] like Figure 1 As shown, the packaging box 1012 has a accommodating cavity 10120. When the composite cushioning packaging structure 1011 is assembled into the accommodating cavity 10120, the cushioning base pad 4 is arranged between the bottom of the accommodating cavity 10120 and the cushioning body 1. The cushioning body 1 is arranged in the accommodating cavity 10120 and is adjacent to the cavity wall of the accommodating cavity 10120, while the top of the cushioning body 1 and the end paper card 2 are adjacent to the top of the accommodating cavity 10120.

[0066] When packaging the packaged product 102 , first place the buffer base 4 at the bottom of the accommodating cavity 10120 , with the side with the accommodating slot 41 facing the top of the accommodating cavity 10120 , and then place the buffer body 1 into the accommodating cavity 10120 .

[0067] When the number of packaged products 102 is one, the packaged product 102 is placed in the hollow portion 112 of the buffer body 1, so that the packaged product 102 is adjacent to the buffer pad 12, and a part of the packaged product 102 is located in the accommodating card slot 41 of the buffer base pad 4; then the end paper card 2 is inserted into the hollow portion 112. As in this embodiment, the end paper card 2 is also sleeved on the packaged product 102 through the assembly hole 211, so that the top of the end paper card 2 is flush with the top of the buffer body 1, and then the packaging box 1012 is packaged.

[0068] When the number of packaged products 102 is one, the first packaged product 102 is placed in the hollow part 112 of the buffer body 1, so that the packaged product 102 is adjacent to the buffer pad 12, and a part of the high packaged product 102 is located in the accommodating slot 41 of the buffer bottom pad 4; the buffer pad block 3 is placed on the first packaged product 102 according to the set position, and then the second packaged product 102 is placed, so that in the axial direction of the right prism, the buffer pad block 3 is placed between two adjacent packaged products 102; then, the packaged products 102 and the buffer pad blocks 3 are repeatedly placed crosswise to the set number (no buffer pad block 3 is required on the last packaged product 102); the end paper card 2 is inserted into the hollow part 112, as in this embodiment, the end paper card 2 is also sleeved on the last packaged product 102 through the assembly hole 211, so that the top of the end paper card 2 is flush with the top of the buffer body 1, and then the packaging box 1012 is packaged.

[0069] In summary, it can be seen that the structure of the bent paper card 11 itself has a certain degree of cushioning and supporting capacity. Based on this, the cushioning pad 12, the end paper card 2 and the cushioning pad 3 (optional) arranged in the hollow part 112, and the cushioning pad 12 placed at the bottom of the cushioning body 1 can effectively support and cushion the packaged product 102 placed in the hollow part 112, thereby preventing the packaged product 102 from being damaged during storage and transportation. Compared with simply using foam to cushion and support the packaged object, the composite cushioning packaging structure 1011 can occupy a smaller space while ensuring at least equivalent cushioning and support for the packaged product 102, which is conducive to improving space utilization, so that more packaged products 102 can be packaged in the same space, or the space occupied by the packaged product 100 after packaging can be reduced, which is more conducive to the storage and transportation of the packaged product 100. At the same time, since the paper card 11 has the ability to fold, it is also more convenient for storage and transportation than foam.

[0070] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
