[0003] At present, some new environmentally friendly supporting materials such as honeycomb paper, corrugated paper, pulp molded products and other materials can replace traditional supporting materials. The structure made of paper material is designed to provide an overall shock-absorbing effect for the internal products of the package. However, this packaging method has the problems of low material utilization and high cost. Summary of the invention

[0045] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0046] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

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

[0048] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0049] In the related art, the packaging can be placed in a packaging box or a packaging case. The packaging can be used to provide support for the product to be packaged, so as to cushion the impact force encountered by the product during transportation or storage, and effectively prevent the product from being damaged or deformed. In order to ensure that the packaging can provide shock absorption and buffering for the entire product to be packaged, the packaging usually completely wraps the product to be packaged. However, such a packaging method has the problems of low material utilization and high cost. In addition, for the buffer tray component of the product to be packaged, two types of trays are usually required: a supporting tray for supporting the product to be packaged and a buffer tray for wrapping the product to be packaged around to play a shock-absorbing role. The two trays cooperate to achieve effective protection. However, the design of the existing buffer tray cannot take into account both the bearing and buffering effects at the local position, and the local position of the product is still susceptible to impact and damage.

[0050] Figure 1 The overall structure of a paper packaging buffer 100 provided by the first embodiment of the present application is shown. Figure 2 The overall side view structure of a paper packaging buffer 100 and a separate enlarged structure of one of the fixing members 20 provided in the first aspect of the embodiment of the present application are shown.

[0051] See also Figure 1 and Figure 2 In a first aspect, an embodiment of the present application provides a paper packaging buffer 100 , comprising a main body 10 and fixing members 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 accommodating portion 11 recessed from the top end 10a thereof, and an inserting compartment 12 enclosed and formed between the bottom end 10b thereof and a bottom plate 110 of the product accommodating portion 11 .

[0053] The fixing member 20 includes a bottom plug connector group 23 , a side plug connector group 22 and a top plug connector group 21 .

[0054] The bottom plug connector assembly 23 includes a bottom connecting plate 230 , a first bottom plug-in component 231 and at least one second bottom plug-in component 232 .

[0055] The side plug connector assembly 22 includes a side enclosure connecting plate 220 and at least one side plug connector 221;

[0056] The top plug connector assembly 21 includes a top connecting plate 210 and a top plug connector 211 .

[0057] The bottom connecting plate 230 , the side connecting plate 220 , the top connecting plate 210 and the top plug-in plate 211 are sequentially intersected and connected in pairs to form a first half-enclosure structure H1 .

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

[0059] The top plug-in unit 211 of the first half-enclosure structure H1 and the first bottom plug-in unit 231 of the second half-enclosure structure H2 are coupled and plug-connected to form a side buffer chamber S0 .

[0060] The side plug-in unit 221 extends from the side surrounding connecting plate 220 to a preset distance in the side buffer cavity S0.

[0061] The paper packaging buffer 100 provided in the first aspect of the present application is a "package"-shaped covering structure formed by the first half-package structure H1 and the second half-package structure H2 of the fixing member 20. The second half-package structure H2 defined in the bottom plug connector group 23 of the fixing member 20 provides a stable bearing function for the main body 10 on one side of the plug-in bin 12. The side buffer cavity S0 formed by the top plug connector 211 of the first half-package structure H1 and the first bottom plug connector 231 of the second half-package structure H2 is coupled and plugged to provide shock absorption and buffering for the main body 10. The integrated fixing member 20 formed by the bottom plug connector group 23, the side plug connector group 22 and the top plug connector group 21 intersecting and connecting in sequence, while realizing multiple functions at the same time, has a high material utilization rate, is conducive to reducing material waste, and can flexibly adjust and arrange the position and number of the fixing member 20 according to the size of the product accommodating portion 11 accommodating products of different sizes, thereby improving packaging work efficiency and reducing costs. The paper packaging buffer 100 provided in the first aspect of the present application can be used for, but is not limited to, protecting products to be packaged in packaging boxes 200 , packaging bags, and the like.

[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 placed in the packaging box after the product to be packaged is placed in the packaging box, or can be placed in the packaging box together with the product to be packaged.

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

[0064] Exemplarily, there may only be contact relationships such as abutment and pasting between the product to be packaged and the product containing portion 11, without an actual structural connection relationship. The size of the product to be packaged can be slightly larger than the size of the product containing portion 11 to achieve full abutment and contact between the product to be packaged and the product containing portion 11, and to avoid the problem that the product to be packaged loosens in the product containing 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 containing portion 11, other buffer structures with appropriate sizes can also be filled in the product containing portion 11 to further define the size of the product containing portion 11 and achieve full abutment and contact between the product to be packaged in the product containing portion 11 and the product containing portion 11 and the buffer structures.

[0066] A plug-in bin 12 is provided at the bottom end of the main body 10 opposite to the product containing portion 11. The plug-in bin 12 is used for plugging and mating with the bottom plugging connection member group 23 and the side plugging connection member group 22 in the fixing member 20 for fixed connection. The specific structure of the plug-in bin 12 and the specific connection relationship between the plug-in bin 12 and the side plug-in member 221, the first bottom plug-in member 231, and the second bottom plug-in member 232 will be further elaborated in the subsequent embodiments.

[0067] Exemplarily, during the packaging use, the side of the main body 10 provided with the plug-in bin 12 is close to the ground, and the side provided with the product containing portion 11 is used to prepare to contain the product to be packaged, and the fixing member 20 is in 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 containing portion 11 to the outer wall of the plug-in bin 12, and rely on the first half-covering structure H1 and the second half-covering structure H2 to enclose a "package" - shaped structure, and simultaneously play the roles of bearing and shock absorption and buffering.

[0069] It should be understood that using the "package" - shaped structure to describe the structural shape formed by the enclosure of the first half-covering structure H1 and the second half-covering structure H2 in the fixing member 20 is only for convenience of description, and it does not substantially limit the structural shape formed by the enclosure of the first half-covering structure H1 and the second half-covering structure H2 in the fixing member 20.

[0070] Exemplarily, the first bottom plug-in 231 and the second bottom plug-in 232 on the bottom plug connector group 23 only have 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 plug connector group 23 is folded in half to form the final first bottom plug-in 231 and the second bottom plug-in 232. The size of the first bottom plug-in 231 and the second bottom plug-in 232 is determined by the distance between the folds, so that the bottom plug connector group 23 only needs to process one blank during the blank production process, and the production efficiency is high.

[0071] At the same time, the connecting plate on the bottom plug connector group 23 is also only creased 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 plug connector group 23 is folded in half to form the final first bottom plug-in 231 and the second bottom plug-in 232. At the same time, the remaining blank between the first bottom plug-in 231 and the second bottom plug-in 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 remaining blank after removing the first bottom plug-in 231 and the second bottom plug-in 232. Therefore, the bottom plug connector group 23 only needs to process one blank during the blank production process, and the production efficiency is high.

[0072] Optionally, the first bottom plug-in 231 and the second bottom plug-in 232 are processed using a single slab during the slab production process, and the sizes of the first bottom plug-in 231 and the second bottom plug-in 232 are directly determined by the sizes of the slab, and then they are spliced ​​with the slab that forms the bottom connecting plate 230 to form the final bottom plug connector group 23.

[0073] Optionally, the bottom connecting plate 230 is processed using a single slab during the slab production process, and the size of the bottom connecting plate 230 is directly determined by the size of the slab, and then spliced ​​with the slab forming the first bottom plug-in 231 and the second bottom plug-in 232 to form the final bottom plug connector group 23.

[0074] Exemplarily, the side plug-in unit 221 on the side plug connector group 22 only defines a fold during the blank production process. Subsequently, in the process of forming the final paper packaging buffer 100 from the blank, the final side plug-in unit 221 is formed by folding the blank used to form the side plug connector group 22. The size of the side plug-in unit 221 is determined by the distance between the folds, so that the side plug connector group 22 only needs to process one blank during the blank production process, and the production efficiency is high.

[0075] At the same time, the side enclosure connecting plates 220 on the side plug connector group 22 are also only creased 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 plug connector group 22 is folded in half to form the final side plug-in unit 221, and the remaining blank between the side plug-ins 221 is used to form the side enclosure connecting plates 220. The size of the side enclosure connecting plates 220 is determined by the size of the remaining blank after removing the side plug-in unit 221, so that the side plug connector group 22 only needs to process one blank during the blank production process, and the production efficiency is high.

[0076] Optionally, the side plug 221 is processed using a single slab during the slab production process, and the size of the side plug 221 is directly determined by the size of the slab, and then spliced ​​with the slab that forms the side enclosure connecting plate 220 to form the final side plug connector set 22.

[0077] Optionally, the side enclosure connecting plate 220 is processed using a single slab during the slab production process, and the size of the side enclosure connecting plate 220 is directly determined by the size of the slab, and then spliced ​​with the slab forming the side plug-in unit 221 to form the final side plug-in connector group 22.

[0078] Exemplarily, the top plug connector group 21 only defines a fold during the blank production process, and then in the process of forming the final paper packaging buffer 100 from the blank, the final top connecting plate 210 and the top plug-in unit 211 are formed by bending the blank used to form the top plug connector group 21. The sizes of the top connecting plate 210 and the top plug-in unit 211 are determined by the distance between the folds, so that the top plug connector group 21 only needs to process one blank during the blank production process, and the production efficiency is high.

[0079] Optionally, the top connecting plate 210 and the top plug-in unit 211 are respectively processed using a single slab during the slab production process, and the sizes of the top connecting plate 210 and the top plug-in unit 211 are directly determined by the sizes of the slab. Subsequently, the slab of the top connecting plate 210 and the slab of the top plug-in unit 211 are spliced ​​to form the final top plug connector group 21.

[0080] The second half package structure H2 defined by the bottom connecting plate 230 , the first bottom plug-in 231 and the second bottom plug-in 232 enables the fixing member 20 to cooperate with the plug-in bin 12 to carry the product to be packaged in the product accommodating portion 11 of the main body 10 .

[0081] Exemplarily, the first bottom plug-in 231 and the second bottom plug-in 232 are kept perpendicular to the bottom connecting plate 230 to provide a better load-bearing effect.

[0082] Optionally, the interval between the first bottom plug-in 231 and the second bottom plug-in 232, and the size of the bottom connecting plate 230 between the first bottom plug-in 231 and the second bottom plug-in 232 forming the second half package structure H2 can be flexibly arranged and adjusted according to the size and weight of the product to be packaged, which is convenient for flexible adjustment.

[0083] At the same time, the bottom connecting plate 230, the side connecting plate 220, the top connecting plate 210 and the top plug-in 211 are sequentially connected to form a first half-enclosure structure H1, wherein the top plug-in 211 of the first half-enclosure structure H1 is coupled and plug-connected with the first bottom plug-in 231 of the second half-enclosure structure H2, and a side buffer cavity S0 is formed on one side of the first half-enclosure structure H1, which can form a complete protective structure for the inner wall of the product accommodating portion 11 and the outer wall of the plug-in bin 12, thereby achieving a shock-absorbing 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 unit 211 are intersected and connected in pairs in sequence. It should be understood that the bottom connecting plate 230, the side connecting plate 220, the top connecting plate 210 and the top plug-in unit 211 are connected in sequence, and the two adjacent connected components 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 components.

[0085] Exemplarily, the product to be packaged can also abut and contact the top plug-in unit 211 in the product containing portion 11, while at the same time there is a gap between the top plug-in unit 211 and the inner wall of the product containing portion 11, and the top plug-in unit 211 and part of the structure of the product containing portion 11 can also enclose to form a cavity, so that the shock-absorbing and buffering effect can be further enhanced on one side of the product to be packaged.

[0086] The top plug-in unit 211 extends vertically into the product containing portion 11, the top plug-in unit 211 is parallel to an inner wall on one side of the product containing portion 11, and the top plug-in unit 211 is perpendicular to an inner wall on the other side of the product containing portion 11 connected to the inner wall on one side. During the slab production process, the size of the top plug-in unit 211 is consistent with the depth or width of the product containing portion 11, so that the required size of the top plug-in unit 211 can be obtained directly according to the size of the product containing portion 11.

[0087] The top plug-in unit 211 and the top connecting plate 210 are kept vertical, the top connecting plate 210 and the side connecting plate 220 are kept vertical, and the side connecting plate 220 and the bottom connecting plate 230 are kept vertical. During the slab production process, the overall size of the fixing part 20 can be directly obtained based on the sizes of the top plug-in unit 211, the top connecting plate 210, the side connecting plate 220 and the bottom connecting plate 230.

[0088] At the same time, during the slab production process, the bottom plug-in connection area 320a, the side plug-in connection area 320b and the top plug-in connection area 320c are directly processed in sequence, and the bottom plug-in connection area 320a and the top plug-in connection area 320c are bent toward the same side of the side plug-in connection area 320b to obtain the required fixing part 20 structure.

[0089] Optionally, the top plug 211 is arranged to fit the inner wall of the product containing portion 11 and extend into the product containing portion 11, thereby achieving a full-covering protection effect while minimizing the impact on the size of the product containing portion 11.

[0090] Optionally, the angle and position of the top plug-in 211 extending into the product accommodating portion 11, the angle between the top plug-in 211 and the product accommodating portion 11, the angle between the top connecting plate 210 and the side connecting plate 220, and the angle between the side connecting plate 220 and the bottom connecting plate 230 are not limited. The sizes of the top plug-in 211, the top connecting plate 210, the side connecting plate 220 and the bottom connecting plate 230 are determined according to the required size of the fixing member 20. The top plug-in 211, the top connecting plate 210, the side connecting plate 220 and the bottom connecting plate 230 can be bent to form different structures, which is convenient and flexible to adjust.

[0091] At the adjacent position of the first half-enclosed structure H1 and the second half-enclosed structure H2, that is, the top plug-in 211 of the first half-enclosed structure H1 and the first bottom plug-in 231 in the second half-enclosed structure H2 are also coupled and plugged, and a side buffer cavity S0 is formed on one side of the first half-enclosed structure H1, that is, on the side closer to the main body 10, to achieve a buffering and shock-absorbing effect.

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

[0093] The plug-in connection method is adopted on the fixing member 20, which can form a stable connection without the need for additional adhesives, saving materials and being more environmentally friendly. At the same time, the structure at the connection position is more beautiful.

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

[0095] The side plug-in 221 is extended by a preset distance in the side buffer cavity S0, further subdividing the side buffer cavity S0, providing structural support for the inside of the side buffer cavity S0, and achieving better buffering and shock absorption effects. At the same time, the side plug-in 221 can also be connected to part of the structure of the main body 10 to further enhance the stable bearing and support effects.

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

[0097] Optionally, the material of the main body 10 and the material of the fixing member 20 can be the same. For example, the material of the main body 10 and the material of the fixing member 20 can be but not limited to cardboard or corrugated paper. Cardboard or corrugated paper has the characteristics of environmental protection, lightness, and pressure resistance.

[0098] Figure 3 A partially enlarged structure of a first slot 130d in a paper packaging buffer 100 provided in an embodiment of the first aspect of the present application is shown.

[0099] See also Figure 3 In some embodiments, the main body 10 also includes a first slot 130d, which is arranged along the second edge 130c of the plug-in bin 12 away from the product accommodating portion 11, and the first bottom plug-in 231 and the second bottom plug-in 232 are at least partially embedded in the first slot 130d, so that the first bottom plug-in 231 and the second bottom plug-in 232 are plugged and connected to the main body 10.

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

[0101] Exemplarily, the first slot 130d on the docking bin 12 is opened along the edge of the slab used to form the docking bin 12 during the slab production process, and the size of the first slot 130d can be directly determined according to the groove size on the slab used to form the docking bin 12.

[0102] Optionally, the first slot 130d is actually opened in the middle of the blank for forming the plug-in bin 12 during the blank production process. In the subsequent process of forming the final paper packaging buffer 100 from the blank, by folding the reserved fold on the blank for forming the plug-in bin 12, part of the slot structure overlaps, 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 setting position of the fold for folding, and two layers of plate structure are stacked at the second edge 130c, so that the material strength is greater, and the plug-in matching relationship between the first bottom plug 231 and the second bottom plug 232 and the first slot 130d is more stable.

[0103] Optionally, the thickness of the first bottom plug-in 231 and the second bottom plug-in 232 as the tenon is slightly larger than the first slot 130d as the mortise, so that the plug-in fitting relationship between the first bottom plug-in 231 and the second bottom plug-in 232 and the first slot 130d is more stable.

[0104] Figure 4 The cross-sectional structure of a paper packaging buffer 100 along the BB direction provided by the embodiment of the first aspect of the present application is shown.

[0105] See also Figure 4 In some embodiments, the first bottom plug-in 231 and the second bottom plug-in 232 include a root 23a and a raised end 23b. The first bottom plug-in 231 and the second bottom plug-in 232 also include an avoidance groove 23c. The avoidance groove 23c extends from the raised end 23b toward the root 23a. At least part of the product accommodating portion 11 is embedded in the avoidance groove 23c, so that the first bottom plug-in 231 and the second bottom plug-in 232 avoid the setting of the product accommodating portion 11.

[0106] In these embodiments, avoidance grooves 23c are provided on the first bottom plug-in 231 and the second bottom plug-in 232, and the avoidance grooves 23c make room for the setting of the product accommodating portion 11, and part of the structure of the product accommodating portion 11 is embedded in the avoidance grooves 23c, further making the plug-in fitting relationship between the fixing member 20 and the main body 10 more stable.

[0107] Exemplarily, the first bottom plug-in 231 and the second bottom plug-in 232 on the bottom plug connector group 23 are pre-creased only at the root 23a and the raised end 23b during the production process of the plate blank. In the process of forming the final paper packaging buffer 100 from the plate blank, the plate blank used to form the bottom plug connector group 23 is folded at the crease of the raised end 23b, and the creases of the root 23a on both sides of the raised end 23b are bent in the direction opposite to the folding direction of the raised end 23b to form the final first bottom plug-in 231 and the second bottom plug-in 232. The size of the first bottom plug-in 231 and the second bottom plug-in 232 is determined by the distance between the creases at the root 23a and the raised end 23b, and the first bottom plug-in 231 and the second bottom plug-in 232 are two-layer plate structures with greater material strength, and the plug-in fitting relationship between the first bottom plug-in 231 and the second bottom plug-in 232 and the first slot 130d is more stable.

[0108] At the same time, the bottom plug connector group 23 includes a plurality of second bottom plugs 232, wherein the avoidance groove 23c on one of the second bottom plugs 232 is provided with a groove at the position of the second bottom plug 232 during the production of the plate blank, and the groove is actually provided in the middle of the second bottom plug 232. In the subsequent process of the plate blank forming the final paper packaging buffer 100, in the plate blank used to form the bottom plug connector group 23, by folding the fold reserved at the position of the second bottom plug 232, the partial structure of the groove overlaps, so that in the final paper packaging buffer 100, the avoidance groove 23c is extended from the protruding end 23b toward the root 23a. The size of the avoidance groove 23c is determined by the setting position of the fold used for folding at the position of the second bottom plug 232, and a two-layer plate structure is provided at the position of the avoidance groove 23c, and the material strength is greater, so that the embedded matching relationship between the partial structure of the product accommodating portion 11 and the avoidance groove 23c is more stable.

[0109] Optionally, the second bottom plug-in 232 is processed using a single slab during the slab production process, and the avoidance groove 23c on the second bottom plug-in 232 is also directly processed on the slab that forms the second bottom plug-in 232. The size of the avoidance groove 23c is directly determined by the size of the avoidance groove 23c formed on the slab. Subsequently, the second bottom plug-in 232 is spliced ​​with the slab that forms the bottom connecting plate 230 to form the final bottom plug connector group 23.

[0110] Optionally, the width dimension of the product accommodating portion 11 as a tenon is slightly larger than the width dimension of the avoidance groove 23c as a mortise, so that the embedded matching relationship between the product accommodating portion 11 and the avoidance groove 23c is more stable.

[0111] Figure 5 The cross-sectional structure of a paper packaging buffer 100 along the CC direction provided by the first aspect embodiment of the present application is shown.

[0112] See also Figure 5 In some embodiments, the first bottom plug-in 231 further includes a connecting tongue 231a extending from the side of the avoidance groove 23c away from the protruding end 23b toward the protruding end 23b, and the connecting tongue 231a penetrates the bottom plate 110 of the product accommodating portion 11 and extends into the product accommodating portion 11.

[0113] In these embodiments, the connecting tongue 231a extending from the avoidance groove 23c penetrates the bottom plate 110 of the product accommodating portion 11 and extends into the product accommodating portion 11, further making the plug-in fitting relationship between the fixing member 20 and the main body 10 more stable.

[0114] Exemplarily, the connecting tongue 231a of the first bottom plug-in unit 231 is provided with only two grooves between the root 23a and the raised end 23b during the production process of the plate blank, and a fold is reserved between the root 23a and the raised end 23b. In the process of forming the final paper packaging buffer 100 from the plate blank, in the plate blank used to form the bottom plug connector group 23, the final connecting tongue 231a is formed by folding in half at the fold at the raised end 23b, and bending the structure between the two grooves. The size of the connecting tongue 231a is determined by the distance between the two grooves and the distance between the root 23a and the raised end 23b. The connecting tongue 231a is a two-layer plate structure with greater material strength, and the plug-in fitting relationship between the connecting tongue 231a and the bottom plate 110 of the product accommodating portion 11 is more stable.

[0115] Optionally, the first bottom plug-in 231 is processed using a single slab during the slab production process, and the connecting tongue 231a on the first bottom plug-in 231 is also directly processed on the slab that forms the first bottom plug-in 231. The size of the connecting tongue 231a is determined by the distance between the grooves opened on the edge of the slab that forms the first bottom plug-in 231. Subsequently, the first bottom plug-in 231 is spliced ​​with the slab that forms the bottom connecting plate 230 to form the final bottom plug connector group 23.

[0116] Optionally, the width dimension of the connecting tongue 231a as the tenon is slightly larger than the width dimension of the bottom plate 110 of the product containing portion 11 as the mortise, so that the embedding and fitting relationship between the connecting tongue 231a and the bottom plate 110 of the product containing portion 11 is more stable.

[0117] Figure 6 The partial structure of the explosive disassembly structure of the main body 10 and the fixing part 20 of a paper packaging buffer 100 provided in the first aspect embodiment of the present application is shown.

[0118] See also Figure 6 In some embodiments, the bottom plate 110 of the product containing portion 11 is provided with a through slot 110a therethrough, the top plug-in unit 211 is embedded in the through slot 110a and connected to the bottom plate 110 of the product containing portion 11 by tenon, and the connecting tongue 231a passes through the through slot 110a and extends into the product containing portion 11.

[0119] In these embodiments, the top plug-in unit 211 and the connecting tongue 231a both realize the mortise and tenon connection and plug-in fitting relationship with the bottom plate 110 of the product containing portion 11 through the same through groove 110a on the bottom plate 110 of the product containing portion 11, which has a higher structural utilization rate and a more stable connection relationship, and further facilitates the realization of the coupling and plug-in connection relationship between the first bottom plug-in unit 231 and the top plug-in unit 211.

[0120] Exemplarily, during the production of the slab, the through slot 110a directly processes the slab of the bottom plate 110 forming the product receiving portion 11, and the size of the through slot 110a is determined by the size of the slot opened on the slab of the bottom plate 110 forming the product receiving portion 11.

[0121] The through slot 110a has an irregular shape, including 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-in member 211, and the shape and size of the opposite end of the through slot 110a are adapted to the connecting tongue 231a, so that the plugging connection relationship between the top plug-in member 211 and the bottom plate 110 of the product receiving portion 11, and the plugging cooperation relationship between the connecting tongue 231a and the bottom plate 110 of the product receiving portion 11 can both be realized through the through slot 110a.

[0122] Both the top plug-in member 211 and the connecting tongue 231a realize the connection relationship with the bottom plate 110 of the product receiving portion 11 through the same through slot 110a, which not only further strengthens the protective effect of the "package" - shaped covering structure of the fixing member 20, but also makes better use of the existing structure on the paper packaging buffer member 100.

[0123] At the same time, the connecting tongue 231a of the top plug-in member 211 and the first bottom plug-in member 231 is limited within the same through slot 110a, and there is no other structure in the middle to hinder, which further facilitates the realization of the coupling plugging connection relationship between the first bottom plug-in member 231 and the top plug-in member 211.

[0124] Fig. 9 Shows Figure 1 The sectional structure along the A - A direction.

[0125] Please refer to Figure 6 And Fig. 9 In some embodiments, the top plug-in member 211 further includes a plug-in body 211a and a first wing plate 211b. One end of the plug-in body 211a intersects and connects with the top connecting plate 210. The opposite end of the plug-in body 211a is embedded in the through slot 110a and is tenon - mortise connected to the bottom plate 110. The first wing plate 211b extends along the two side edges of the plug-in body 211a, and the first wing plate 211b bends towards the side of the connecting tongue 231a and extends into the gap between the avoidance slot 23c and the connecting tongue 231a, and is coupled and plugged with the first bottom plug-in member 231.

[0126] The side buffer cavity S0 further includes a first buffer sub - cavity S1, and the first wing plate 211b, the plug-in body 211a and the connecting tongue 231a enclose to form the first buffer sub - cavity S1.

[0127] In these embodiments, the first wing plate 211b is bent to achieve the coupling and plug-in connection between the top plug-in 211 and the first bottom plug-in 231, and at the same time, a first buffer sub-cavity S1 is formed between the top plug-in 211 and the connecting tongue 231a, and the side buffer cavity S0 is further subdivided, thereby further enhancing the shock-absorbing and buffering effect of the side of the main body 10 at the setting position of the fixing member 20.

[0128] Exemplarily, the plug-in body 211a and the first wing plate 211b in the top plug-in unit 211 are formed by directly processing the slab forming the top plug-in unit 211 during the slab production process, and the sizes of the plug-in body 211a and the first wing plate 211b are directly determined by the sizes of the plug-in body 211a and the first wing plate 211b processed on the slab forming the top plug-in unit 211.

[0129] The first wing plate 211b is bent and passes through the gap between the connecting tongue 231a and the avoidance groove 23c, and abuts against the connecting tongue 231a on the side of the connecting tongue 231a away from the top plug-in 211. The plug-in fitting 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 are more stable, and the shock-absorbing 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, further facilitating the coupling and insertion of the first wing plate 211b of the top plug 211 with the first bottom plug 231, and further facilitating the formation of the first buffer sub-cavity S1.

[0131] Optionally, the first wing plate 211 b is bent and directly abuts against the connecting tongue 231 a at a side of the connecting tongue 231 a close to the top plug-in unit 211 .

[0132] Figure 7 The figure shows a partial structure of another angle of the explosive disassembly structure of the main body 10 and the fixing member 20 of a paper packaging buffer 100 provided by the first aspect of the present application. Figure 8 Shows Figure 7 Cross-sectional structure along DD direction.

[0133] See also Figure 7 and Figure 8 In some embodiments, the main body 10 also 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 accommodating portion 11. The second side plate 130 is connected to a first edge 120a of the first side plate 120 away from the bottom plate 110, and extends from the first edge 120a across the bottom plate 110 to enclose a plug-in bin 12 on the side away from the product accommodating portion 11.

[0134] The main body 10 also includes a second slot 130e and a third slot 120b. The second slot 130e is arranged along an edge adjacent to a side where the second side panel 130 is connected to the first side panel 120, and the third slot 120b is arranged along an edge adjacent to a side where the first side panel 120 is connected to the second side panel 130. The side plug-in 221 is embedded in the second slot 130e and the third slot 120b so that the side plug-in 221 is plug-connected to the main body 10.

[0135] In these embodiments, the side plug-in connector 221 on the side plug-in connector group 22 is plugged into and matched with the second slot 130e on the second side panel 130 and the third slot 120b on the first side panel 120, thereby realizing the plug-in connection between the side plug-in connector group 22 and the first side panel 120 and the second side panel 130, further making the connection relationship between the fixing member 20 and the main body 10 more stable.

[0136] The main body 10 is formed by a three-layer plate structure, in which the bottom plate 110 and the first side plate 120 are internally enclosed to form a product holding portion 11 structure, while the second side plate 130 extends from the first edge 120a of the first side plate 120 over the bottom plate 110 to form a plug-in bin 12 structure on the periphery, thereby covering the product holding portion 11 structure and forming the overall outer shape structure of the main body 10.

[0137] Exemplarily, the bottom plate 110 is a flat, unbendable plate structure, the first side plate 120 is connected to the outer edge of the bottom plate 110, and the bottom plate 110 and the first side plate 120 remain vertical, so that the size of the product accommodating portion 11 can be directly limited according to the size of the first side plate 120 and the bottom plate 110, which makes it convenient to directly determine the size of the product accommodating portion 11 according to the size of the bottom plate 110 and the first side plate 120 in the slab during the slab production process.

[0138] At the same time, the first side panel area and the bottom panel area are directly processed during the production process of the slab, and the product accommodating portion 11 structure can be formed by bending the first side panel area toward the bottom panel area.

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

[0140] Exemplarily, the second side panel 130 is directly attached to the first side panel 120, so that the size of the docking bin 12 and the overall dimensions of the main body 10 can be directly determined based on the size of the second side panel 130, which facilitates the determination of the overall dimensions of the main body 10 based on the size of the second side panel 130 in the slab during the slab production process.

[0141] At the same time, during the slab production process, the second side panel area is directly processed at the first edge 120a of the first side panel area away from the bottom panel area, and the second side panel 130 area is bent in a direction opposite to the bending direction of the first side panel 120 area to obtain the overall appearance structure of the plug-in bin 12 structure and the main body 10.

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

[0143] Exemplarily, 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 size of the groove on the slab.

[0144] The third slot 120 b 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 120 b can be directly determined according to the size of the groove on the slab.

[0145] At the same time, the side plug-in 221 on the side connecting plate 220 only marks the crease during the blank production process. Subsequently, in the process of forming the final paper packaging buffer 100 from the blank, the final side plug-in 221 is formed by folding the side connecting plate 220. The size of the side plug-in 221 is determined by the distance between the folds, so that the fixing part 20 only needs to process one blank during the blank production process, and the production efficiency is high.

[0146] Optionally, the side plug-in 221 is processed using a single slab during the slab production process, and the size of the side plug-in 221 is directly determined by the size of the slab used to form the side plug-in 221, and then spliced ​​with the slab that forms the side enclosure connecting plate 220 to form the final side enclosure connecting member group.

[0147] Optionally, the second slot 130e is actually opened in the middle of the second side panel 130 during the production of the blank. In the subsequent process of forming the final paper packaging buffer 100 from the blank, by folding the reserved fold on the second side panel 130, a part of the structure of the second slot 130e overlaps, so that in the final paper packaging buffer 100, the second slot 130e is connected to the edge of the second side panel 130 adjacent to the first side panel 120. The size of the second slot 130e is determined by the setting position of the fold for folding.

[0148] Optionally, the third slot 120b is actually opened in the middle of the first side panel 120 during the production of the blank. In the subsequent process of forming the final paper packaging buffer 100 from the blank, by folding the reserved fold on the first side panel 120, a part of the structure of the third slot 120b overlaps, so that in the final paper packaging buffer 100, the third slot 120b is connected to the edge adjacent to the first side panel 120 and the second side panel 130. The size of the third slot 120b is determined by the setting position of the fold for folding.

[0149] Optionally, the first side panel 120 is fitted with the second side panel 130, and the second slot 130e and the third slot 120b at least partially overlap, so that at the fitting position of the first side panel 120 and the second side panel 130, two layers of plate structure are stacked around the second slot 130e and the third slot 120b, the material strength is greater, and the plug-in fitting relationship between the side plug-in 221 and the second slot 130e and the third slot 120b is more stable.

[0150] Please continue reading Figure 7 and Fig. 9 In some embodiments, the second side panel 130 also includes a side panel body 130a and a second wing plate 130b. One side of the side panel body 130a is connected to the first side panel 120, and the other side of the side panel body 130a is enclosed on the side away from the product accommodating portion 11 to form a plug-in bin 12. The second wing plate 130b is extended along both ends of the side panel body 130a, and the second wing plate 130b is bent toward one side of the product accommodating portion 11 and plugged into the bottom plate 110.

[0151] The side buffer cavity S0 further includes a second buffer sub-cavity S2, and the second wing plate 130b encloses and forms the second buffer sub-cavity S2.

[0152] In these embodiments, the second wing plate 130b is bent and plugged into the bottom plate 110, and the second wing plate 130b encloses a second buffer sub-cavity S2, further subdividing the side buffer cavity S0, further enhancing the shock-absorbing and buffering effect of the side of the main body 10 at the setting position of the fixing member 20, and further enhancing the shock-absorbing and buffering effect surrounding the product holding portion 11.

[0153] Exemplarily, the side panel body 130a and the second wing plate 130b in the second side panel 130 are formed by directly processing the blank that forms the second side panel 130 during the blank production process, and the sizes of the side panel body 130a and the second wing plate 130b are directly determined by the sizes of the side panel body 130a and the second wing plate 130b processed on the blank that forms the second side panel 130.

[0154] The second wing plate 130b is bent and passes through the gap reserved at the edge of the bottom plate 110 to achieve a plug-in connection with the bottom plate 110. The second wing plates 130b of the second side plates 130 on both sides of the edge of the bottom 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 relationship between the second wing plate 130b and the bottom plate 110 is better, the setting of the second buffer sub-cavity S2 is more stable, and the shock-absorbing and buffering effect is better.

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

[0156] Optionally, when the bottom plate 110 is used as the tenon, the thickness of the bottom plate 110 is slightly larger than the gap reserved on the second wing plate 130b, so that the plug-in connection between the bottom plate 110 and the second wing plate 130b is 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 bottom plate 110, so that the plug-in connection between the second wing plate 130b and the bottom plate 110 is more stable.

[0158] See also Figure 7 In some embodiments, the fixing member 20 is disposed at the plug-in connection position between the second wing plate 130 b and the bottom plate 110 , and the fixing member 20 extends and covers the second wing plate 130 b .

[0159] In these embodiments, the setting position of the first buffer sub-cavity S1 overlaps with the second buffer sub-cavity S2 along the side direction perpendicular to the main body 10, further enhancing the shock-absorbing and buffering effect at the setting position of the fixing member 20, and the fixing member 20 covers the connection position between the second wing plate 130b and the bottom plate 110, so that the paper packaging buffer 100 is more compact as a whole, has greater structural strength, and is more beautiful.

[0160] Exemplarily, the second wing panels 130 b are disposed at both ends of the bottom plate 110 of the product containing portion 11 , and two fixing members 20 are disposed at both ends of the product containing portion 11 .

[0161] Optionally, the product accommodating part 11 has an irregular shape, the second wing plate 130b is arranged at irregular intervals along the edge of the bottom plate 110 of the product accommodating part 11, and the fixing member 20 is arranged in cooperation with the position of the second wing plate 130b and covers the second wing plate 130b, which is convenient for flexible adjustment.

[0162] Please continue to refer to Figure 1 , in some embodiments, the paper packaging buffer 100 further includes a supporting member 30. The supporting member 30 includes a supporting plate 31 and a supporting plug 32. The supporting plate 31 is arranged at the edge of the side of the inserting bin 12 away from the product accommodating part 11, the supporting plug 32 extends into the inserting bin 12, and the supporting member 30 is arranged between two adjacent fixing members 20. The supporting plug 32 extends a preset distance towards the product accommodating part 11 in the inserting bin 12 and is distributed.

[0163] In these embodiments, the supporting member 30 is in a "mountain" shape. On the side of the inserting bin 12 away from the product accommodating part 11, it plays an auxiliary role in bearing the main body 10 between two adjacent fixing members 20, and can better meet the bearing requirements and flexibly adjust the position and quantity.

[0164] It should be understood that using the "mountain" shape structure to describe the structural shape formed by the supporting member 30 is only for convenience of description, and it 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. A supporting member 30 is arranged between the fixing members 20 arranged at both ends of the length dimension of the main body 10 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 quantity of the supporting member 30 can also be flexibly adjusted.

[0167] Exemplarily, the supporting plug 32 on the supporting member 30 only demarcates the crease during the production of the board blank. Subsequently, during the process of forming the final paper packaging buffer 100 from the board blank part, the final supporting plug 32 is formed by folding the board blank part used to form the supporting member 30. The size of the supporting plug 32 is determined by the distance between the creases, so that only one board blank needs to be processed during the production of the supporting plug 32, and the production efficiency is high.

[0168] At the same time, the support plate 31 on the support member 30 is also 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 support member 30 is folded in half to form the final supporting plug-in 32, and the remaining blank between the first bottom plug-in 231 and the second bottom plug-in 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 remaining blank after removing the first bottom plug-in 231 and the second bottom plug-in 232, so that the bottom plug connector group 23 only needs to process one blank during the blank production process, and the production efficiency is high.

[0169] Optionally, the support plug-in 32 is processed using a single slab during the slab production process, and the size of the support plug-in 32 is directly determined by the size of the slab, and then it is spliced ​​with the slab that forms the support plate 31 to form the final support member 30.

[0170] Optionally, the support plate 31 is processed using a single slab during the slab production process, and the size of the support plate 31 is directly determined by the size of the slab, and then it is spliced ​​with the slab forming the support plug-in 32 to form the final support member 30.
