Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to a paper packaging cushioning component, a packaging box, and a blank for forming the paper packaging cushioning component. Background Technology

[0002] In the field of product packaging, cushioning support structures are crucial for protecting products from external impacts during transportation and storage. Traditional support structures can be made of foam plastic or bubble wrap. While these materials offer some protection, they are often non-biodegradable, increasing the difficulty of packaging waste disposal and negatively impacting the environment.

[0003] Currently, some new environmentally friendly support materials, such as honeycomb paper, corrugated paper, and molded pulp products, can replace traditional support materials. Structural designs using paper materials are used to provide overall shock absorption for the products inside the packaging. However, this packaging method suffers from low material utilization and high costs. Summary of the Invention

[0045] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.

[0046] In the description of this application, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.

"Vertical" is not vertical in the strict sense, but within the allowable tolerance range. "Parallel" is not parallel in the strict sense, but within the allowable tolerance range.

[0047] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0048] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. It should also be noted in the description of this application that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0049] In related technologies, packaging components can be placed inside packaging boxes or cartons. Packaging components provide support for the product to be packaged, cushioning impacts encountered during transportation or storage and effectively preventing damage or deformation. To ensure the packaging component provides overall shock absorption for the product, it typically completely encloses it. However, this packaging method suffers from low material utilization and high cost. Furthermore, cushioning components for the product typically require two types of clips: a support clip to hold the product and a cushioning clip to surround the product and provide shock absorption. These two types work together to achieve effective protection. However, existing cushioning clip designs cannot simultaneously provide both support and cushioning in certain areas, leaving some parts of the product vulnerable to impact and damage.

[0050] Figure 1 This illustration shows the overall structure of a paper packaging cushioning member 100 provided in the first aspect embodiment of this application. Figure 2 The illustration shows an overall side view of a paper packaging cushioning member 100 and an enlarged view of one of the fixing members 20 provided in the first aspect embodiment of this application.

[0051] Please see Figure 1 and Figure 2 In one aspect, embodiments of this application provide a paper packaging cushioning member 100, including a main body 10 and fasteners 20 located at opposite ends of the main body 10.

[0052] The main body 10 includes a top end 10a and a bottom end 10b, and also has a product receiving portion 11 recessed by its own top end 10a and an insertion compartment 12 formed between its own bottom end 10b and the bottom plate 110 of the product receiving portion 11.

[0053] The fastener 20 includes a bottom insertion connector group 23, a side insertion connector group 22, and a top insertion connector group 21.

[0054] The bottom connector assembly 23 includes a bottom connector plate 230, a first bottom insert 231, and at least one second bottom insert 232.

[0055] The side-inserting connecting member set 22 comprises a side surrounding connecting plate 220 and at least one side inserting member 221;

[0056] The top-inserting connecting member set 21 comprises a top connecting plate 210 and a top inserting member 211.

[0057] Wherein, the bottom connecting plate 230, the side surrounding connecting plate 220, the top connecting plate 210 and the top inserting member 211 are sequentially connected pairwise intersectingly to form a first half-wrapping structure H1.

[0058] The first bottom inserting member 231 and the second bottom inserting member 232 are formed by extending from the bottom connecting plate 230 toward the top connecting plate 210 and are spaced apart from each other, and the bottom connecting plate 230, the first bottom inserting member 231 and the second bottom inserting member 232 can define a second half-wrapping structure H2.

[0059] The top inserting member 211 of the first half-wrapping structure H1 and the first bottom inserting member 231 of the second half-wrapping structure H2 are coupled, inserted and connected to form a side buffer cavity S0.

[0060] The side inserting member 221 extends from the side surrounding connecting plate 220 into the side buffer cavity S0 by a preset distance and is distributed.

[0061] In the paper packaging buffer 100 provided by the embodiment of the first aspect of the present application, the main body 10 forms a "wrapping"-shaped cladding structure through the first half-wrapping structure H1 and the second half-wrapping structure H2 of the fixing member 20. While the second half-wrapping structure H2 defined in the bottom inserting connecting member set 23 of the fixing member 20 provides stable bearing for the main body 10 on one side of the inserting bin 12, the side buffer cavity S0 formed by the coupled inserting connection between the top inserting member 211 of the first half-wrapping structure H1 and the first bottom inserting member 231 of the second half-wrapping structure H2 provides shock absorption and buffering effects for the main body 10. The integrated fixing member 20 formed by sequentially intersecting connection of the bottom inserting connecting member set 23, the side inserting connecting member set 22 and the top inserting connecting member set 21 realizes multiple functions at the same time, has high material utilization, is beneficial to reducing material waste, and can flexibly adjust and arrange the position and quantity of the fixing member 20 according to the size of the product accommodating portion 11 for accommodating products of different sizes, improving packaging work efficiency and reducing costs. The paper packaging buffer 100 provided by the embodiment of the first aspect of the present application can, but is not limited to, protect products to be packaged in a packaging box 200, a packaging bag, etc.

[0062] Taking the paper packaging buffer 100 protecting the product to be packaged in the packaging box as an example, the paper packaging buffer 100 can be loaded into the packaging box after the product to be packaged is placed into the packaging box, or can be loaded into the packaging box together with the product to be packaged.

[0063] There is also an accommodating relationship between the product to be packaged and the paper packaging buffer member 100, and the product to be packaged can be at least partially embedded in the product accommodating portion 11. Therefore, the buffer packaging member can be combined with the product to be packaged and then loaded into the packaging box.

[0064] For example, there may only be contact relationships such as abutting or attaching between the product to be packaged and the product accommodating portion 11, without an actual structural connection relationship. The size of the product to be packaged may be slightly larger than the size of the product accommodating portion 11, so as to achieve sufficient abutting and contact between the product to be packaged and the product accommodating portion 11, and avoid the problem that the product to be packaged becomes loose in the product accommodating portion 11 and accidentally falls off.

[0065] Optionally, when the size of the product to be packaged is smaller than the size of the product accommodating portion 11, other buffer structures of appropriate sizes can also be filled into the product accommodating portion 11, so as to further define the size of the product accommodating portion 11, and achieve sufficient abutting and contact between the product to be packaged and the product accommodating portion 11 and the buffer structures in the product accommodating portion 11.

[0066] An insertion bin 12 is provided at the bottom end of the main body 10 opposite to the product accommodating portion 11, and the insertion bin 12 is used for insertion fit and fixed connection with the bottom insertion connecting member set 23 and the side insertion connecting member set 22 in the fixing member 20. The specific structure of the insertion bin 12 and the specific connection relationship between the insertion bin 12 and the side insertion member 221, the first bottom insertion member 231 and the second bottom insertion member 232 will be further elaborated in the following embodiments.

[0067] For example, during the packaging process, the side of the main body 10 provided with the insertion bin 12 is close to the ground, and the side provided with the product accommodating portion 11 is used for ready accommodating the product to be packaged, and the fixing member 20 achieves contact with the ground or the bottom wall of the packaging box 200.

[0068] The fixing member 20 can completely cover from the inner wall of the product accommodating portion 11 to the outer side wall of the insertion bin 12, and forms a "wrapped" structure by enclosing the first half-wrapping structure H1 and the second half-wrapping structure H2, which realizes both bearing and shock absorption and buffering functions.

[0069] It should be understood that describing the structural shape enclosed by the first half-wrapping structure H1 and the second half-wrapping structure H2 in the fixing member 20 by using a "wrapped" structure is only for convenient description, and it does not substantially limit the structural shape enclosed by the first half-wrapping structure H1 and the second half-wrapping structure H2 in the fixing member 20.

[0070] For example, the first bottom insert 231 and the second bottom insert 232 on the bottom insert connector assembly 23 are only marked with creases during the blank production process. Subsequently, in the process of forming the final paper packaging cushion 100 from the blank, the final first bottom insert 231 and the second bottom insert 232 are formed by folding the blank used to form the bottom insert connector assembly 23. The size of the first bottom insert 231 and the second bottom insert 232 is determined by the distance between the creases, so that the bottom insert connector assembly 23 only needs to be processed on one blank during the blank production process, resulting in high production efficiency.

[0071] Meanwhile, the connecting plate on the bottom insert connector assembly 23 also only has creases marked during the blank production process. Subsequently, in the process of forming the final paper packaging buffer 100 from the blank, the blank used to form the bottom insert connector assembly 23 is folded in half to form the final first bottom insert 231 and second bottom insert 232. At the same time, the remaining blank between the first bottom insert 231 and the second bottom insert 232 is used to form the bottom connecting plate 230. The size of the bottom connecting plate 230 is determined by the size of the blank remaining after removing the blank used to form the first bottom insert 231 and the second bottom insert 232. This makes it possible for the bottom insert connector assembly 23 to only process one blank during the blank production process, resulting in high production efficiency.

[0072] Optionally, the first bottom insert 231 and the second bottom insert 232 are processed from a single slab during the slab production process. The dimensions of the first bottom insert 231 and the second bottom insert 232 are directly determined by the dimensions of the slab. They are then spliced ​​with the slab that forms the bottom connecting plate 230 to form the final bottom insert connector assembly 23.

[0073] Optionally, the bottom connecting plate 230 is processed from a single slab during the slab production process. The size of the bottom connecting plate 230 is directly determined by the size of the slab. It is then spliced ​​with the slab that forms the first bottom insert 231 and the second bottom insert 232 to form the final bottom insert connector assembly 23.

[0074] For example, the side insert 221 on the side insert connector assembly 22 is only marked with creases during the blank production process. Then, in the process of forming the final paper packaging buffer 100 from the blank, the final side insert 221 is formed by folding the blank used to form the side insert connector assembly 22. The size of the side insert 221 is determined by the distance between the creases, so that the side insert connector assembly 22 only needs to be processed on one blank during the blank production process, resulting in high production efficiency.

[0075] Meanwhile, the side connecting plate 220 on the side insert connector assembly 22 is also marked with creases during the blank production process. Subsequently, in the process of forming the final paper packaging buffer 100 from the blank, the blank used to form the side insert connector assembly 22 is folded in half to form the final side insert 221. At the same time, the remaining blank between the side inserts 221 is used to form the side connecting plate 220. The size of the side connecting plate 220 is determined by the size of the blank remaining after removing the blank used to form the side insert 221. This makes it possible for the side insert connector assembly 22 to only need to process one blank during the blank production process, resulting in high production efficiency.

[0076] Optionally, the side insert 221 is processed from a single slab during the slab production process. The size of the side insert 221 is directly determined by the size of the slab. It is then spliced ​​with the slab that forms the side connecting plate 220 to form the final side insert connector assembly 22.

[0077] Optionally, the side panel connecting plate 220 is processed from a single slab during the slab production process. The size of the side panel connecting plate 220 is directly determined by the size of the slab. It is then spliced ​​with the slab that forms the side insert 221 to form the final side insert connector assembly 22.

[0078] For example, the top connector assembly 21 is only marked with creases during the blank production process. Subsequently, in the process of forming the final paper packaging buffer 100 from the blank, the blank used to form the top connector assembly 21 is bent to form the final top connecting plate 210 and top insert 211. The dimensions of the top connecting plate 210 and top insert 211 are determined by the distance between the creases, so that the top connector assembly 21 only needs to be processed on one blank during the blank production process, resulting in high production efficiency.

[0079] Optionally, the top connecting plate 210 and the top insert 211 are processed from separate slabs during the slab production process. The dimensions of the top connecting plate 210 and the top insert 211 are directly determined by the dimensions of the slab. Subsequently, the slabs of the top connecting plate 210 and the top insert 211 are spliced ​​together to form the final top insert connector assembly 21.

[0080] The second semi-enclosed structure H2 defined by the bottom connecting plate 230, the first bottom plug 231, and the second bottom plug 232 enables the fastener 20 to cooperate with the insertion compartment 12 to carry the product to be packaged in the product receiving part 11 of the main body 10.

[0081] For example, the first bottom plug 231 and the second bottom plug 232 are perpendicular to the bottom connecting plate 230, so as to play a better role in bearing.

[0082] Optionally, the spacing between the first bottom insert 231 and the second bottom insert 232, as well as the size of the bottom connecting plate 230 between the first bottom insert 231 and the second bottom insert 232 forming the second semi-enclosed structure H2, can be flexibly arranged and adjusted according to the size and weight of the product to be packaged, allowing for convenient and flexible adjustment.

[0083] Meanwhile, the bottom connecting plate 230, the side connecting plate 220, the top connecting plate 210 and the top plug-in 211 are connected in sequence to form the first semi-enclosed structure H1. The top plug-in 211 of the first semi-enclosed structure H1 is coupled and plugged into the first bottom plug-in 231 of the second semi-enclosed structure H2. A side buffer cavity S0 is formed on one side of the first semi-enclosed structure H1, which can form a complete protective structure for the inner wall of the product receiving part 11 and the outer wall of the plug-in compartment 12, so as to realize the shock absorption and buffering effect on the main body 10 and the product to be packaged.

[0084] The bottom connecting plate 230, the side connecting plate 220, the top connecting plate 210, and the top plug-in 211 are connected in pairs in sequence. This should be understood as the bottom connecting plate 230, the side connecting plate 220, the top connecting plate 210, and the top plug-in 211 being connected in sequence, and the two adjacent connected parts are not completely parallel or extend along the same plane, that is, there is an angle of not less than 0° and not more than 180° between the two adjacent connected parts.

[0085] For example, the product to be packaged can also abut and contact the top plug 211 inside the product receiving part 11, while there is a gap between the top plug 211 and the inner wall of the product receiving part 11, and the top plug 211 and part of the structure of the product receiving part 11 can also enclose to form a cavity, so that a further enhanced shock absorption and cushioning effect can be achieved on the side of the product to be packaged.

[0086] The top insert 211 extends vertically into the product receiving part 11. The top insert 211 is parallel to one side of the inner wall of the product receiving part 11, and the other side of the inner wall of the top insert 211 connected to one side of the inner wall of the product receiving part 11 is perpendicular to it. During the blank production process, the size of the top insert 211 is consistent with the depth or width of the product receiving part 11, so that the required size of the top insert 211 can be obtained directly from the size of the product receiving part 11.

[0087] The top plug 211 is perpendicular to the top connecting plate 210, the top connecting plate 210 is perpendicular to the side connecting plate 220, and the side connecting plate 220 is perpendicular to the bottom connecting plate 230. During the slab production process, the overall size of the fastener 20 can be directly obtained from the dimensions of the top plug 211, the top connecting plate 210, the side connecting plate 220, and the bottom connecting plate 230.

[0088] Meanwhile, during the slab production process, the bottom insertion connection area 320a, the side insertion connection area 320b, and the top insertion connection area 320c, which are connected in sequence, are directly machined. The required fastener 20 structure can be obtained by bending the bottom insertion connection area 320a and the top insertion connection area 320c toward the same side of the side insertion connection area 320b.

[0089] Optionally, the top plug 211 is fitted to the inner wall of the product receiving part 11 and extends into the product receiving part 11, so as to achieve the same full-coverage protection without affecting the size of the product receiving part 11 as much as possible.

[0090] Optionally, the angle and position of the top insert 211 extending into the product receiving part 11, the included angle between the top insert 211 and the product receiving part 11, the included angle between the top connecting plate 210 and the side connecting plate 220, and the included angle between the side connecting plate 220 and the bottom connecting plate 230 are not limited. The dimensions of the top insert 211, the top connecting plate 210, the side connecting plate 220, and the bottom connecting plate 230 are determined according to the dimensions of the required fastener 20. The top insert 211, the top connecting plate 210, the side connecting plate 220, and the bottom connecting plate 230 can be bent into different structures, which is convenient and flexible for adjustment.

[0091] At the adjacent positions of the first semi-enclosed structure H1 and the second semi-enclosed structure H2, that is, the top plug-in 211 of the first semi-enclosed structure H1 and the first bottom plug-in 231 in the second semi-enclosed structure H2 are also coupled and plugged in. On one side of the first semi-enclosed structure H1, that is, the side closer to the main body 10, a side buffer cavity S0 is formed, which plays a role in buffering and shock absorption.

[0092] The specific coupling and insertion relationship between the top plug-in 211 and the first bottom plug-in 231, as well as the specific arrangement of the side buffer cavity S0, will be further explained in the following embodiments.

[0093] Using a plug-in connection on the fastener 20 can form a stable connection without the need for additional adhesives, saving materials and being more environmentally friendly, while also making the structure at the connection point more aesthetically pleasing.

[0094] The specific connection methods of the first bottom plug-in 231 and the second bottom plug-in 232, as well as the specific connection method of the top plug-in 211, will be further described in the following embodiments.

[0095] The side insert 221 extends a preset distance within the side buffer cavity S0, further subdividing the side buffer cavity S0 and providing structural support for the interior of the side buffer cavity S0. This achieves a better buffering and shock absorption effect. At the same time, the side insert 221 can also be connected to the main body 10 structure to further enhance the stability, load-bearing capacity, and support effect.

[0096] The specific connection method of the side plug-in 221 will be further described in the following embodiments.

[0097] Optionally, the materials of the main body 10 and the fastener 20 can be the same. For example, the materials of the main body 10 and the fastener 20 can be, but are not limited to, cardboard or corrugated paper. Cardboard or corrugated paper is environmentally friendly, lightweight, and pressure-resistant.

[0098] Figure 3 This illustration shows a partially enlarged structure at the first slot 130d in a paper packaging cushioning member 100 provided in the first aspect embodiment of this application.

[0099] Please see Figure 3 In some embodiments, the body 10 further includes a first slot 130d, which is disposed along the second edge 130c of the insertion compartment 12 on the side away from the product receiving portion 11. The first bottom plug 231 and the second bottom plug 232 are at least partially embedded in the first slot 130d so that the first bottom plug 231 and the second bottom plug 232 are plugged into the body 10.

[0100] In these embodiments, the first bottom plug 231 and the second bottom plug 232 cooperate through the first slot 130d on the plug-in compartment 12 to achieve the plug-in connection between the fastener 20 and one end of the main body 10, which is simple and reliable.

[0101] For example, the first slot 130d on the plug-in compartment 12 is opened along the edge of the slab used to form the plug-in compartment 12 during the slab production process, and the size of the first slot 130d can be directly determined according to the slot size on the slab used to form the plug-in compartment 12.

[0102] Optionally, the first slot 130d is actually formed in the middle of the blank used to form the insertion compartment 12 during the blank production process. In the subsequent process of forming the final paper packaging buffer 100 from the blank, the slot partially overlaps by folding along the creases pre-reserved on the blank used to form the insertion compartment 12, so that in the final paper packaging buffer 100, the first slot 130d is connected to the second edge 130c. The size of the first slot 130d is determined by the location of the creases used for folding, and two layers of sheet material are stacked at the second edge 130c, resulting in greater material strength and a more stable insertion relationship between the first bottom insert 231 and the second bottom insert 232 and the first slot 130d.

[0103] Optionally, the thickness of the first bottom insert 231 and the second bottom insert 232, which serve as tenons, should be slightly larger than that of the first slot 130d, which serves as mortises, so as to make the insertion and engagement relationship between the first bottom insert 231 and the second bottom insert 232 and the first slot 130d more stable.

[0104] Figure 4 The diagram shows a cross-sectional structure along the BB direction of a paper packaging cushioning member 100 provided in the first aspect embodiment of this application.

[0105] Please see Figure 4 In some embodiments, the first bottom plug 231 and the second bottom plug 232 include a root 23a and a protruding end 23b. The first bottom plug 231 and the second bottom plug 232 also include a relief groove 23c. The relief groove 23c extends from the protruding end 23b toward the root 23a. At least a portion of the product receiving portion 11 is embedded in the relief groove 23c so that the first bottom plug 231 and the second bottom plug 232 avoid the arrangement of the product receiving portion 11.

[0106] In these embodiments, the first bottom plug 231 and the second bottom plug 232 are provided with clearance grooves 23c. The clearance grooves 23c provide space for the product receiving part 11, and part of the structure of the product receiving part 11 is embedded in the clearance grooves 23c, which further makes the plug-in relationship between the fastener 20 and the main body 10 more stable.

[0107] For example, the first bottom plug 231 and the second bottom plug 232 on the bottom plug connector assembly 23 have creases reserved only at the root 23a and the protruding end 23b during the blank production process. In the process of forming the final paper packaging cushion 100 from the blank, the first bottom plug 231 and the second bottom plug 232 are formed by folding the blank used to form the bottom plug connector assembly 23 at the crease at the protruding end 23b and bending the creases at the root 23a on both sides of the protruding end 23b in the opposite direction to the folding direction of the protruding end 23b. The dimensions of the first bottom plug 231 and the second bottom plug 232 are determined by the distance between the crease at the root 23a and the protruding end 23b. The first bottom plug 231 and the second bottom plug 232 are two-layer board structures with greater material strength, and the insertion and mating relationship between the first bottom plug 231 and the second bottom plug 232 and the first slot 130d is more stable.

[0108] Meanwhile, the bottom insert connector assembly 23 includes multiple second bottom inserts 232. One of the second bottom inserts 232 has a relief groove 23c. During the blank production process, a slot is formed at the location of the second bottom insert 232. This slot is actually located in the middle of the second bottom insert 232. In the subsequent process of forming the final paper packaging cushioning component 100 from the blank, the grooved portion overlaps by folding along the crease reserved at the location of the second bottom insert 232. This results in the relief groove 23c extending from the protruding end 23b towards the root 23a in the final paper packaging cushioning component 100. The size of the relief groove 23c is determined by the location of the crease at the location of the second bottom insert 232. Furthermore, the relief groove 23c has a two-layer board structure, resulting in greater material strength and a more stable fit between the part of the product receiving portion 11 and the relief groove 23c.

[0109] Optionally, the second bottom insert 232 is processed using a separate slab during the slab production process. The clearance groove 23c on the second bottom insert 232 is also directly processed on the slab that forms the second bottom insert 232. The size of the clearance groove 23c is directly determined by the size of the clearance groove 23c formed on the slab. Then, the second bottom insert 232 is spliced ​​with the slab that forms the bottom connecting plate 230 to form the final bottom insert connector assembly 23.

[0110] Optionally, the width of the product receiving portion 11, which serves as the tenon, is slightly larger than the width of the relief groove 23c, which serves as the mortise, so as to make the embedded fit between the product receiving portion 11 and the relief groove 23c more stable.

[0111] Figure 5 The illustration shows a cross-sectional structure along the CC direction of a paper packaging cushioning member 100 provided in the first aspect embodiment of this application.

[0112] Please see Figure 5 In some embodiments, the first bottom insert 231 further includes a connecting tongue 231a extending from the side of the relief groove 23c away from the protruding end 23b toward the protruding end 23b, the connecting tongue 231a penetrating the bottom plate 110 of the product receiving portion 11 and extending into the product receiving portion 11.

[0113] In these embodiments, the connecting tongue 231a extending from the clearance groove 23c penetrates the bottom plate 110 of the product receiving portion 11 and extends into the product receiving portion 11, further making the insertion and engagement relationship between the fastener 20 and the main body 10 more stable.

[0114] For example, the connecting tongue 231a of the first bottom insert 231 has two slots only between the root 23a and the protruding end 23b during the blank production process, and a crease is reserved between the root 23a and the protruding end 23b. In the process of forming the final paper packaging buffer 100 from the blank, the final connecting tongue 231a is formed by folding the blank at the crease at the protruding end 23b and bending the structure between the two slots. The size of the connecting tongue 231a is determined by the distance between the two slots and the distance between the root 23a and the protruding end 23b. The connecting tongue 231a is a two-layer board structure with greater material strength, and the insertion fit between the connecting tongue 231a and the bottom plate 110 of the product receiving part 11 is more stable.

[0115] Optionally, the first bottom insert 231 is processed using a separate slab during the slab production process. The connecting tongue 231a on the first bottom insert 231 is also directly processed on the slab that forms the first bottom insert 231. The size of the connecting tongue 231a is determined by the distance between the slots opened on the edge of the slab that forms the first bottom insert 231. Then, the first bottom insert 231 is spliced ​​with the slab that forms the bottom connecting plate 230 to form the final bottom insert connector assembly 23.

[0116] Optionally, the width of the connecting tongue 231a, which serves as the tenon, is slightly larger than the width of the base plate 110 of the product receiving part 11, which serves as the mortise, so as to make the embedded fit between the connecting tongue 231a and the base plate 110 of the product receiving part 11 more stable.

[0117] Figure 6 This illustration shows a partial structure of an explosive dismantling structure of a paper packaging cushioning member 100 body 10 and a fixing member 20 provided in the first aspect embodiment of this application.

[0118] Please see Figure 6 In some embodiments, the bottom plate 110 of the product receiving part 11 is provided with a through groove 110a, the top plug 211 is embedded in the through groove 110a and tenoned with the bottom plate 110 of the product receiving part 11, and the connecting tongue 231a extends into the product receiving part 11 through the through groove 110a.

[0119] In these embodiments, the top plug 211 and the connecting tongue 231a are connected to the bottom plate 110 of the product receiving part 11 through the same through groove 110a on the bottom plate 110 of the product receiving part 11, which achieves a mortise and tenon connection and plug-in fit relationship with the bottom plate 110 of the product receiving part 11. The structure has a higher utilization rate and the connection relationship is more stable, which further facilitates the coupling and plug-in connection relationship between the first bottom plug 231 and the top plug 211.

[0120] For example, the through groove 110a is processed directly on the blank of the base plate 110 that forms the product receiving part 11 during the blank production process, and the size of the through groove 110a is determined by the size of the groove opened on the blank of the base plate 110 that forms the product receiving part 11.

[0121] The through slot 110a is irregularly shaped and includes two ends with different shapes and sizes. The shape and size of one end of the through slot 110a are adapted to the top plug 211, and the shape and size of the other end of the through slot 110a are adapted to the connecting tongue 231a, so that the plug-in connection between the top plug 211 and the base plate 110 of the product receiving part 11, as well as the plug-in engagement between the connecting tongue 231a and the base plate 110 of the product receiving part 11, can be achieved through the through slot 110a.

[0122] Both the top plug 211 and the connecting tongue 231a are connected to the bottom plate 110 of the product receiving part 11 through the same through groove 110a, which further strengthens the protective function of the "package" shaped covering structure of the fastener 20, while making higher use of the existing structure on the paper packaging buffer 100.

[0123] Meanwhile, the connecting tongue 231a of the top plug-in 211 and the first bottom plug-in 231 is confined within the same through slot 110a, with no other structural obstructions in between, which further facilitates the coupling and plugging connection between the first bottom plug-in 231 and the top plug-in 211.

[0124] Figure 9 It shows Figure 1 Cross-sectional structure along the AA direction.

[0125] Please see Figure 6 and Figure 9 In some embodiments, the top plug-in 211 further includes a plug-in body 211a and a first protective wing plate 211b. One end of the plug-in body 211a is connected to the top connecting plate 210. The other end of the plug-in body 211a is embedded in the through groove 110a and tenon-mortise connected to the bottom plate 110. The first protective wing plate 211b extends along both sides of the plug-in body 211a and bends towards the connecting tongue 231a and is inserted into the gap between the recessed clearance groove 23c and the connecting tongue 231a, and is coupled and plugged into the first bottom plug-in 231.

[0126] The side buffer cavity S0 also includes a first buffer sub-cavity S1, which is formed by the first protective wing plate 211b, the plug body 211a and the connecting tongue 231a.

[0127] In these embodiments, the first protective wing plate 211b is bent, which realizes the coupling and plugging connection between the top plug 211 and the first bottom plug 231, while forming a first buffer sub-cavity S1 between the top plug 211 and the connecting tongue 231a, further subdividing the side buffer cavity S0, and further enhancing the shock absorption and buffering effect of the side of the main body 10 at the setting position of the fixing member 20.

[0128] For example, the plug body 211a and the first wing plate 211b in the top plug 211 are directly formed by processing the slab that forms the top plug 211 during the slab production process. The dimensions of the plug body 211a and the first wing plate 211b are directly determined by the dimensions of the plug body 211a and the first wing plate 211b obtained by processing on the slab that forms the top plug 211.

[0129] The first protective wing plate 211b is bent and passes through the gap between the connecting tongue 231a and the clearance groove 23c. It abuts against the connecting tongue 231a on the side of the connecting tongue 231a away from the top plug-in 211. The insertion and fit relationship between the top plug-in 211 and the connecting tongue 231a is better, the setting and formation of the first buffer sub-cavity S1 is more stable, and the shock absorption and buffering effect is better.

[0130] The through slot 110a allows the top plug 211 and the connecting tongue 231a to pass through the same through slot 110a, which further facilitates the coupling and insertion of the first protective wing plate 211b of the top plug 211 with the first bottom plug 231, and further facilitates the formation of the first buffer sub-cavity S1.

[0131] Optionally, the first wing plate 211b is bent and directly abuts against the connecting tongue 231a on the side of the connecting tongue 231a near the top insert 211.

[0132] Figure 7 This illustration shows a partial structure from another angle of the explosive dismantling structure of a paper packaging cushioning member 100 body 10 and a fixing member 20 provided in the first aspect embodiment of this application. Figure 8 It shows Figure 7 Cross-sectional structure along the DD direction.

[0133] Please see Figure 7 and Figure 8 In some embodiments, the main body 10 further includes a bottom plate 110, a first side plate 120, and a second side plate 130 connected in sequence. The bottom plate 110 and the first side plate 120 enclose the product receiving portion 11. The second side plate 130 is connected to the first edge 120a of the first side plate 120 away from the bottom plate 110 and extends beyond the bottom plate 110 from the first edge 120a, enclosing the insertion compartment 12 on the side away from the product receiving portion 11.

[0134] The main body 10 also includes a second slot 130e and a third slot 120b. The second slot 130e is disposed along the adjacent edge of the side where the second side plate 130 is connected to the first side plate 120. The third slot 120b is disposed along the adjacent edge of the side where the first side plate 120 is connected to the second side plate 130. The side plug 221 is inserted into the second slot 130e and the third slot 120b so that the side plug 221 is plugged into and connected to the main body 10.

[0135] In these embodiments, the side plug 221 on the side plug connector assembly 22 is plugged into the second slot 130e on the second side plate 130 and the third slot 120b on the first side plate 120 to realize the plug-in connection between the side plug connector assembly 22 and the first side plate 120 and the second side plate 130, thereby making the connection between the fastener 20 and the main body 10 more stable.

[0136] The main body 10 is formed by a three-layer plate structure, wherein the bottom plate 110 and the first side plate 120 enclose the product receiving part 11 structure inside, while the second side plate 130 extends beyond the bottom plate 110 from the first edge 120a of the first side plate 120 and encloses the insertion compartment 12 structure on the outside, covering the product receiving part 11 structure and forming the overall shape structure of the main body 10.

[0137] For example, the base plate 110 is a flat, non-bending, single-piece sheet structure. The first side plate 120 is connected to the outer edge of the base plate 110. The base plate 110 and the first side plate 120 are perpendicular to each other, so that the size of the product receiving part 11 can be directly defined based on the size of the first side plate 120 and the base plate 110. This makes it convenient to directly determine the size of the product receiving part 11 based on the size of the base plate 110 and the first side plate 120 in the slab during the slab production process.

[0138] Meanwhile, the first side plate area and the bottom plate area are directly processed during the slab production process, and the product receiving part 11 structure can be formed by bending the first side plate area toward the bottom plate area.

[0139] Optionally, the angle between the base plate 110 and the first side plate 120 and the bending method of the base plate 110 and the first side plate 120 are not limited, but are determined according to the required size of the product receiving part 11 and the shape of the product to be packaged that the product receiving part 11 needs to accommodate. The base plate 110 and the first side plate 120 can be bent to obtain different required structures, which is convenient and flexible to adjust.

[0140] For example, the second side plate 130 is directly attached to the first side plate 120, so that the size of the insertion compartment 12 and the overall external size of the main body 10 can be directly determined based on the size of the second side plate 130, which makes it convenient to determine the overall external size of the main body 10 based on the size of the second side plate 130 in the slab during the slab production process.

[0141] Meanwhile, during the slab production process, the second side plate area is directly processed at the first edge 120a on the side of the first side plate area away from the bottom plate area. The second side plate 130 area is bent in the opposite direction to the bending direction of the first side plate 120 area to obtain the overall shape structure of the insertion compartment 12 structure and the main body 10.

[0142] Optionally, the angle between the second side plate 130 and the first side plate 120 and the bending method of the second side plate 130 are not limited. The second side plate 130 is determined according to the required shape and size of the main body 10. The second side plate 130 can be bent to obtain other different structures as required, which is convenient and flexible.

[0143] For example, the second slot 130e on the second side plate 130 has been opened along the edge adjacent to the first side plate 120111 during the slab production process, and the size of the second slot 130e can be directly determined according to the slot size on the slab.

[0144] The third slot 120b on the first side plate 120 has been opened along the edge adjacent to the second side plate 130 during the slab production process, and the size of the third slot 120b can be directly determined according to the slot size on the slab.

[0145] Meanwhile, the side insert 221 on the side connecting plate 220 only has creases marked during the blank production process. Then, in the process of forming the final paper packaging buffer 100 from the blank, the side insert 221 is formed by folding the side connecting plate 220. The size of the side insert 221 is determined by the distance between the creases, so that the fastener 20 only needs to process one blank during the blank production process, resulting in high production efficiency.

[0146] Optionally, the side insert 221 is processed using a separate slab during the slab production process. The size of the side insert 221 is directly determined by the size of the slab used to form the side insert 221. It is then spliced ​​with the slab that forms the side connecting plate 220 to form the final side connecting assembly.

[0147] Optionally, the second slot 130e is actually formed in the middle of the second side plate 130 during the blank production process. In the subsequent process of forming the final paper packaging cushioning component 100 from the blank, by folding along the pre-reserved crease on the second side plate 130, a portion of the structure of the second slot 130e overlaps, so that in the final paper packaging cushioning component 100, the second slot 130e is connected to the edge adjacent to the second side plate 130 and the first side plate 120. The size of the second slot 130e is determined by the location of the crease used for folding.

[0148] Optionally, the third slot 120b is actually formed in the middle of the first side plate 120 during the blank production process. In the subsequent process of forming the final paper packaging cushioning component 100 from the blank, by folding along the creases pre-reserved on the first side plate 120, a portion of the structure of the third slot 120b overlaps, so that in the final paper packaging cushioning component 100, the third slot 120b is connected to the adjacent edges of the first side plate 120 and the second side plate 130. The size of the third slot 120b is determined by the location of the creases used for folding.

[0149] Optionally, the first side plate 120 and the second side plate 130 are fitted together, and the second slot 130e and the third slot 120b overlap at least partially, so that at the fitting position of the first side plate 120 and the second side plate 130, the second slot 130e and the third slot 120b are surrounded by two layers of board structure, which has greater material strength and makes the insertion and engagement relationship between the side plug 221 and the second slot 130e and the third slot 120b more stable.

[0150] Please continue reading Figure 7 and Figure 9 In some embodiments, the second side plate 130 further includes a side plate body 130a and a second wing plate 130b. One side of the side plate body 130a is connected to the first side plate 120. The side plate body 130a forms an insertion compartment 12 on the side away from the product receiving part 11 opposite to the other side. The second wing plate 130b extends along both ends of the side plate body 130a. The second wing plate 130b is bent toward the product receiving part 11 and inserted into the bottom plate 110.

[0151] The side buffer cavity S0 also includes a second buffer sub-cavity S2, which is formed by the second protective wing plate 130b surrounding it.

[0152] In these embodiments, the second wing plate 130b is bent and connected to the bottom plate 110. The second wing plate 130b surrounds and forms a second buffer sub-cavity S2, further subdividing the side buffer cavity S0, further enhancing the shock absorption and buffering effect of the main body 10 at the setting position of the fastener 20, and further enhancing the shock absorption and buffering effect around the product receiving part 11.

[0153] For example, the side plate body 130a and the second wing plate 130b in the second side plate 130 are directly formed by processing the blank that forms the second side plate 130 during the blank production process. The dimensions of the side plate body 130a and the second wing plate 130b are directly determined by the dimensions of the side plate body 130a and the second wing plate 130b obtained by processing on the blank that forms the second side plate 130.

[0154] The second wing plate 130b is bent and passes through the gap reserved at the edge of the base plate 110 to achieve a plug-in connection with the base plate 110. The second wing plates 130b of the second side plates 130 on both sides of the edge of the base plate 110 pass through the same gap. The second wing plates 130b on both sides are bent to form an "M" shape. The plug-in connection between the second wing plate 130b and the base plate 110 is better, the setting of the second buffer sub-cavity S2 is more stable, and the shock absorption and buffering effect is better.

[0155] Optionally, a gap is reserved on the second wing plate 130b, and the base plate 110 passes through the gap on the second wing plate 130b to achieve a plug-in connection with the base plate 110.

[0156] Optionally, when the base plate 110 is used as a tenon, the thickness of the base plate 110 is slightly larger than the gap reserved on the second wing plate 130b, so as to make the interlocking connection between the base plate 110 and the second wing plate 130b more stable.

[0157] Optionally, when the second wing plate 130b is used as a tenon, the thickness of the second wing plate 130b is slightly larger than the gap reserved on the base plate 110, so as to make the interlocking connection between the second wing plate 130b and the base plate 110 more stable.

[0158] Please see Figure 7 In some embodiments, the fastener 20 is disposed at the insertion connection position between the second wing plate 130b and the base plate 110, and the fastener 20 extends and covers the second wing plate 130b.

[0159] In these embodiments, the first buffer sub-cavity S1 is positioned to overlap with the second buffer sub-cavity S2 along the side direction perpendicular to the main body 10, further enhancing the shock absorption and buffering effect at the position of the fixing member 20. The fixing member 20 also covers the connection position between the second protective wing plate 130b and the bottom plate 110, making the paper packaging buffer member 100 more compact, stronger, and more aesthetically pleasing.

[0160] For example, the second protective wing plate 130b is provided at both ends of the bottom plate 110 of the product receiving part 11, and two fasteners 20 are provided at both ends of the product receiving part 11.

[0161] Optionally, the product accommodating portion 11 has an irregular shape, the second flap plates 130b are arranged at irregular intervals along the edge of the bottom plate 110 of the product accommodating portion 11, and the fixing members 20 are arranged matching the positions of the second flap plates 130b and wrap the second flap plates 130b, facilitating flexible adjustment.

[0162] Please continue to refer to Figure 1 , in some embodiments, the paper packaging buffer 100 further comprises a supporting member 30, the supporting member 30 comprises a supporting plate 31 and a supporting insert 32, the supporting plate 31 is arranged at an edge of the insertion bin 12 on a side away from the product accommodating portion 11, the supporting insert 32 extends into the insertion bin 12, the supporting member 30 is arranged between two adjacent fixing members 20, and the supporting insert 32 extends a preset distance toward the product accommodating portion 11 in the insertion bin 12.

[0163] In these embodiments, the supporting member 30 is in a "mountain" shape, and on the side of the insertion bin 12 away from the product accommodating portion 11, it plays a role of auxiliary supporting the main body 10 between two adjacent fixing members 20, and the position and number can be flexibly adjusted according to the bearing requirements.

[0164] It should be understood that describing the structural shape formed by the supporting member 30 with the "mountain" shaped structure is only for convenience of description, and does not substantially limit the structural shape of the supporting member 30.

[0165] Exemplarily, the length dimension of the main body 10 is much larger than its height dimension and width dimension, and the supporting member 30 is arranged between the fixing members 20 arranged at both ends of the main body 10 in the length dimension, so as to help share the bearing function of the fixing members 20.

[0166] When the dimension of the main body 10 in a certain direction is much larger than the dimensions in other directions, the supporting member 30 is arranged between two adjacent fixing members 20 along this direction. While helping to share the bearing function of the fixing members 20, the position and number of the supporting member 30 can also be flexibly adjusted.

[0167] Exemplarily, only creases are marked for the supporting insert 32 on the supporting member 30 during the slab production process, and then in the process of forming the final paper packaging buffer 100 from the slab blank, the final supporting insert 32 is formed by folding the slab blank used for forming the supporting member 30. The dimension of the supporting insert 32 is determined by the distance between the creases, so that only one slab needs to be processed during the slab production process, resulting in high production efficiency.

[0168] Meanwhile, the support plate 31 on the support member 30 is also marked with creases during the blank production process. Subsequently, in the process of forming the final paper packaging buffer 100 from the blank, the blank used to form the support member 30 is folded in half to form the final support insert 32. At the same time, the remaining blank between the first bottom insert 231 and the second bottom insert 232 is used to form the bottom connecting plate 230. The size of the bottom connecting plate 230 is determined by the size of the blank remaining after removing the blank used to form the first bottom insert 231 and the second bottom insert 232. This makes the bottom insert connecting member group 23 only need to process one blank during the blank production process, resulting in high production efficiency.

[0169] Optionally, the support insert 32 is processed from a single slab during the slab production process. The size of the support insert 32 is directly determined by the size of the slab. It is then spliced ​​with the slab that forms the support plate 31 to form the final support component 30.

[0170] Optionally, the support plate 31 is processed from a single slab during the slab production process. The size of the support plate 31 is directly determined by the size of the slab. It is then spliced ​​with the slab that forms the support insert 32 to form the final support component 30.
