Description

Technical Field

[0001] The utility model relates to the technical field of cardboard boxes for storing or transporting objects or materials, and particularly relates to a filling buffer board. Background Art

[0002] During the packaging and transportation of items, the filling buffer board is often placed between items of different sizes or between the item and the packaging box to play a role of filling and buffering. Currently, the filling buffer materials used in the process of item packaging and transportation include foamed plastics, bubble films, corrugated cardboard boxes, pulp molding, silica gel or silica gel pads, wooden or fiber boards, metal or plastic foot support boards, etc. Among them, the corrugated cardboard box has the characteristics of good environmental protection, low cost, light weight, easy customization, degradable and easy to handle, printable, etc., and is a commonly used filling buffer material in the process of item packaging and transportation. Currently, the item buffer board is usually integrally arranged with the packaging box on the cut piece and folded to form a packaging box with a buffer board.

[0003] The utility model of the Chinese patent with the publication number of CN219258000U discloses a packaging box with a buffer structure, which includes an integral box body. The box body is integrally provided with a box cover. On both sides inside the box body, side buffer parts are integrally provided respectively. Inside the box cover, a top surface buffer part is integrally provided. The top surface buffer part is connected with a card board part for strengthening the formation of the side buffer part. The matching design of the side buffer parts on both sides inside the box body of the packaging box with a buffer structure of the utility model and the top surface buffer part on the box cover realizes the six-sided buffering of the product inside the packaging box and can comprehensively protect the product during transportation. This utility model integrally designs the buffer part, that is, the part that plays a role of buffering and protecting the item, with the box body. During the folding process, relatively complex steps are required, and the buffer part needs to be designed according to the size of the item. When cutting the cut piece, a new cutting scheme needs to be designed, and the production is relatively time-consuming and the use is not flexible enough.

[0004] In addition, the commonly used filling buffer board made of corrugated cardboard boxes needs to be glued or bound, and the production is relatively complex. Using foamed plastic materials to manufacture the filling buffer board requires specific molds, and the materials are not easy to degrade and recycle. Summary of the Utility Model

[0005] Aiming at the problems that the current filling buffer board needs to be glued or bound, the production is relatively time-consuming, and some materials are not easy to recycle, etc., the utility model provides a filling buffer board, which uses environmentally friendly and degradable materials and can be made only by simply folding the cut piece with creases, without gluing or binding, has a rebound buffering effect, the materials are light, and the use scenarios are flexible.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A filling buffer plate, comprising a bearing part and a lining part, wherein the bearing part and the lining part are connected by a main crease. The bearing part comprises a bearing plate and a support plate connected by an outer crease. The lining part comprises a lining plate and a lining support plate connected by an inner crease. The bearing part and the lining part are folded to form a filling buffer block. The filling buffer plate comprises two parts, namely the bearing part and the lining part. The bearing part and the lining part are connected by a main crease. The bearing part and the lining part can be folded to form a filling buffer block. When the filling buffer block is subjected to pressure, it generates a resilient force to achieve the function of buffering and protecting the article.

[0008] Preferably, the bearing plate comprises a first bearing plate and a second bearing plate, the support plate comprises a first support plate and a second support plate. One side of the first bearing plate is connected to the first support plate by a first outer crease, the other side of the first bearing plate is connected to the second support plate by a second outer crease, and the other side of the second support plate is connected to the second bearing plate by a third outer crease.

[0009] The first support plate, the first bearing plate, the second support plate and the second bearing plate are sequentially connected by outer creases and can form the bearing part of the filling buffer block after folding.

[0010] Preferably, the lining part comprises a first lining plate and a second lining plate, the lining support plate comprises a first lining support plate and a second lining support plate. One side of the first lining plate is connected to the first lining support plate by a first inner crease, the other side of the first lining plate is connected to the second lining support plate by a second inner crease, and the second lining support plate is connected to the second lining plate by a third inner crease. The first lining support plate, the first lining plate, the second lining support plate and the second lining plate are sequentially connected by inner creases and can form the lining part of the filling buffer block after folding.

[0011] Further, the lining part further comprises a third lining plate, the third lining plate is connected to the first lining support plate by a fourth inner crease, and the ratio of the length of the third lining plate to the length of the second lining plate is 20% - 30%. The third lining plate plays a role in bearing the pressure of the first lining support plate in the filling buffer block. Since the force is distributed decreasingly from the fourth inner crease to the third lining plate, the length of the third lining plate does not have to be the same as that of the second lining plate, and a bearing effect can be achieved and materials can be saved within the range of 20% - 30% of the length of the second lining plate.

[0012] Preferably, the support plates each have an outer support crease located on the midline in the length direction of the support plate, and the inner lining support plate has an inner support crease located on the midline in the length direction of the inner lining support plate. The ratio of the length of the support plate to the length of the load-bearing plate is 25% - 35%, and the ratio of the length of the inner lining support plate to the length of the inner lining plate is 25% - 35%. The outer support crease and the inner support crease symmetrically fold the support plate and the inner lining support plate in the width direction. The length of the support plate within a certain range of the length of the load-bearing plate can avoid poor buffering effect of the filling buffer block due to the overly long load-bearing plate and overly short support plate. The ratio range should be preferably 25% - 35%, and the same applies to the ratio of the inner lining support plate to the inner lining plate in terms of length.

[0013] Preferably, at least one gasket is provided on the inner crease. A part of the gasket is located on the inner lining plate, and the other part is located on the inner lining support plate. The ratio of the length of the gasket to the length of the inner lining support plate is 45% - 55%, and the ratio of the width of the gasket to the width of the inner lining support plate is 10% - 20%. The values of the length and width of the gasket are restricted within a certain range of the size of the inner lining support plate to avoid insufficient elasticity of the gasket after folding.

[0014] Furthermore, the gasket is folded in half to form a limiting block located between the inner lining plate and the inner lining support plate, and the limiting block connects the inner lining plate and the inner lining support plate. The limiting block can help provide a certain deformation space when the filling buffer block deforms under pressure, and the limiting block can provide a certain elastic force to avoid tearing of the cut pieces when the filling buffer block is compressed to the limit position under pressure.

[0015] Furthermore, the bearing part of the filling buffer block surrounds the inner lining part, the first load-bearing plate and the second inner lining plate are attached, the second load-bearing plate and the first inner lining plate are attached, the first support plate and the first inner lining support plate are attached, and the second support plate and the second inner lining support plate are attached.

[0016] The beneficial effects of the present utility model are as follows:

[0017] The structure of the filling buffer plate is relatively simple. The filling buffer block with a buffering and protecting function can be formed by simply folding the bearing part and the inner lining part, without the need for gluing or binding between various parts of the cut pieces after folding, which is convenient, fast, and highly efficient in production. At the same time, the filling buffer block is independently installed between the packing box and the article, with flexible use and high reuse rate. The material used for the filling buffer plate is an environmentally friendly and degradable material, such as corrugated cardboard and similar materials. The filling buffer plate is overall lightweight, and the material can be recycled and reused. Description of the Drawings

[0028] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0029] The present invention provides a filling buffer plate, and the preferred embodiments of the full filling buffer plate are described below.

[0030] Embodiment 1

[0031] As Figure 1 shown, this figure is the unfolded state of the filling buffer board before folding, including a bearing part 1 and a lining part 2. The bearing part 1 and the lining part 2 are connected by a main crease 31. The bearing part 1 includes a bearing board 11 and a support board 12 connected by an outer crease 32. The lining part 2 includes a lining board 21 and a lining support board 22 connected by an inner crease 33. And there is also a third lining board 213 connected to the lining support board 22. The cutting material is corrugated cardboard. The second bearing board 112, the second support board 122, the first bearing board 111 and the first support board 121 are sequentially connected by a third outer crease 323, a second outer crease 322 and a first outer crease 321; the second lining board 212, the second lining support board 222, the first lining board 211, the first lining support board 221 and the third lining board 213 are sequentially connected by a third inner crease 333, a second inner crease 332, a first inner crease 331 and a fourth inner crease 334. The crease 3 is formed during the cutting process of the cutting piece to facilitate the folding of the cutting piece. Two gaskets 23 are provided on the first inner crease 331 between the first lining board 211 and the first lining support board 221, on the second inner crease 332 between the first lining board 211 and the second lining support board 222, on the third inner crease 333 between the second lining board 212 and the second lining support board 222, and on the fourth inner crease 334 between the third lining board 213 and the first lining support board 221. The gaskets 23 are processed during the overall cutting of the filling buffer board. The filling buffer board is folded to obtain a filling buffer block 4, which is used to be placed in the item packing box and plays a buffering and protecting role during the transportation and loading / unloading of the item.

[0032] As Figure 1As shown, the width of the bearing plate 11 is slightly greater than its length. The first bearing plate 111 and the second bearing plate 112 are of the same size. Their main function is to bear the pressure generated by the shaking and extrusion of the packaged items during loading, unloading, transportation, etc., playing a role in buffering and protection. To ensure the stability after folding and avoid stress caused by size mismatch between the inner lining part 2 and the bearing part 1 due to extrusion, the length of the inner lining board 21 is slightly less than that of the bearing plate 11. The length of the inner lining board 21 is reduced by two cardboard thicknesses compared to the length of the bearing plate 11. The first inner lining board 211 and the second inner lining board 212 are of the same size, and the width of the inner lining board 21 is slightly greater than its length. The first support plate 121, the second support plate 122, the first inner lining support plate 221, and the second inner lining support plate 222 are of the same length. The lengths of the support plate 12 and the inner lining support plate 22 need to form a certain ratio with the bearing plate 11 and the inner lining board 21. Since the cutting pieces are mostly made of cardboard, the filling buffer block 4 composed of the overly long bearing plate 11 and the inner lining board 21 is prone to collapse, and the functions of the support plate 12 and the inner lining support plate 22 after folding become negligible. The ratio of the length of the support plate 12 to the length of the bearing plate 11 is 25% - 35%, and the ratio of the length of the inner lining support plate 22 to the length of the inner lining board 21 is 25% - 35%. In this embodiment, the ratio of the length of the support plate 12 to the length of the bearing plate 11 is approximately 30%, and the ratio of the length of the inner lining support plate 22 to the length of the inner lining board 21 is approximately 27%.

[0033] As Figure 1 and Figure 8As shown, the ratio of the length of the third inner lining plate 213 to the length of the second inner lining plate 212 is 20% - 30%. In this embodiment, the ratio of the length of the third inner lining plate 213 to the length of the second inner lining plate 212 is 23%. The cut piece is folded to form a filling buffer block 4. The third inner lining plate 213 is attached to the second inner lining plate 212 to serve as the support inside the filling buffer block 4. When the bearing plate 11 receives external pressure, the support plate 12 and the inner lining support plate 22 are further folded to generate elastic deformation, and the filling buffer block 4 generates an elastic force outward in the direction perpendicular to the bearing plate 11. During this process, sliding occurs between the first inner lining plate 211 and the first bearing plate 111, between the second inner lining plate 212 and the second bearing plate 112, between the first support plate 121 and the first inner lining support plate 221, between the second support plate 122 and the second inner lining support plate 222, and between the third inner lining plate 213 and the second inner lining plate 212. Subsequently, the inner lining part 2 needs to set a space for the deformation of the cut piece, and the length of the third inner lining plate 213 should be less than that of the second inner lining plate 212. When the bearing plate 11 of the filling buffer block 4 is externally squeezed, the force between the first inner lining support plate 221 and the second inner lining plate 212 is mainly generated between the fourth inner crease 334 between the third inner lining plate 213 and the first inner lining support plate 221 and the second inner lining plate 212. The pressure that the third inner lining plate 213 needs to bear is relatively small. Subsequently, to save materials, and the length of the third inner lining plate 213 needs to meet the length for opening the gasket 23, the length of the third inner lining plate 213 is set at 20% - 30% of the length of the second inner lining plate 212.

[0034] As Figure 1 and Figure 4As shown, the gasket 23 is disposed on the first inner crease 331 between the first inner liner 211 and the first inner liner support plate 221, on the second inner crease 332 between the first inner liner 211 and the second inner liner support plate 222, on the third inner crease 333 between the second inner liner 212 and the second inner liner support plate 222, and on the fourth inner crease 334 between the third inner liner 213 and the first inner liner support plate 221. And half of the gasket 23 is disposed on each side of the crease 3 along its length. A gasket 23 is provided at both the 1 / 3 and 2 / 3 positions on the crease 3 where the gasket 23 is located. During the cutting process of the cut piece, the cutting tool cuts the length of the gasket 23 perpendicular to the crease 3, and presses two creases 3 of the gasket 23 in the direction parallel to the crease 3, one located on the inner liner 21 and the other located on the inner liner support plate 22. After folding the cut piece, the gasket 23 is folded along its own crease 3 to form a limiting block 24, and the folding direction is opposite to the folding direction of the inner liner 21 and the inner liner support plate 22 that form the crease 3 where the gasket 23 is located. The limiting block 24 has a certain elasticity, can provide a certain elastic force for the filling buffer block 4, and when the filling buffer block 4 is compressed to the maximum extent, to avoid the rupture of the cut piece caused by the extrusion between the bearing part 1 and the inner liner part 2, the limiting block 24 provides a filling of the thickness of two cut pieces, so that the filling buffer block 4 reaches the compression limit, and avoids the rupture of the cut piece and thus losing elasticity. The ratio of the length of the gasket 23 to the length of the inner liner support plate 22 is 45% - 55%. The length dimension of the gasket 23 affects the elasticity of the folded limiting block 24. Limiting the length of the gasket 23 within this range can enable the gasket 23 to provide a certain elasticity while preventing the crease 3 of the gasket 23 located on the inner liner support plate 22 from reaching the inner crease 33 of the inner liner support plate 22. In this embodiment, the length of the gasket 23 is 47% of the length of the inner liner support plate 22; the ratio of the width of the gasket 23 to the width of the inner liner support plate 22 is 10% - 20%. The advantage of setting the width of the gasket 23 within this range is that while matching its length, it can be provided at multiple positions on the crease 3 where it is located.

[0035] As Figures 2 to 8 shown, describe the folding steps of the filling buffer plate in Embodiment 1:

[0036] A. As Figure 2 shown, Figure 2 is the state when the cut piece of the filling buffer plate in Embodiment 1 is laid flat;

As Figure 3As shown, the third inner liner 213 is folded upward along the fourth inner crease 334 between the third inner liner 213 and the first inner liner support plate 221 to an angle of 45°. At the same time, the two gaskets 23 between the third inner liner 213 and the first inner liner support plate 221 are folded in the opposite direction of the folding of the third inner liner 213 along their own creases 3, and two limiting blocks 24 are formed; the first inner liner support plate 221 is folded downward along its own inner support crease 35 to an angle of 90°; the first inner liner support plate 221 is folded upward along the first inner crease 331 between the first inner liner support plate 221 and the first inner liner 211 to an angle of 45°. At the same time, the two gaskets 23 between the first inner liner support plate 221 and the first inner liner 211 are folded in the opposite direction of the folding of the first inner liner support plate 221 along the inner creases 3 inside the two, and two limiting blocks 24 are formed;

[0038] C. As Figure 4 As shown, the first inner liner 211 is folded upward along the second inner crease 332 between the first inner liner 211 and the second inner liner support plate 222 to an angle of 45°. At the same time, the two gaskets 23 between the first inner liner 211 and the second inner liner support plate 222 are folded in the opposite direction of the folding of the first inner liner 211 along the inner creases 3 inside the two, and two limiting blocks 24 are formed; the second inner liner support plate 222 is folded downward along its own inner support crease 35 to an angle of 90°; the second inner liner support plate 222 is folded upward along the third inner crease 333 between the second inner liner support plate 222 and the second inner liner support plate 222 to an angle of 45°. At the same time, the two gaskets 23 between the second inner liner 212 and the second inner liner support plate 222 are folded in the opposite direction of the folding of the second inner liner support plate 222 along the inner creases 3 inside the two, and two limiting blocks 24 are formed;

[0039] D. As Figure 5 As shown, after step C is completed, the third inner liner 213 is attached to the second inner liner 212, and the first inner liner 211 and the second inner liner 212 are arranged opposite to each other and are parallel;

[0040] E. As Figure 6 As shown, the first support plate 121 is folded downward along its own inner support crease 35 to an angle of 90°; the second inner liner 212 is folded upward along the main crease 31 between the second inner liner 212 and the first support plate 121 to an angle of 45°; the folded first support plate 121 and the first inner liner support plate 221 are attached; the outer support crease 34 of the first support plate 121 and the inner support crease 35 of the first inner liner support plate 221 are attached;

[0041] F. As Figure 7As shown, fold the first support plate 121 upward along the first outer crease 321 between the first support plate 121 and the first bearing plate 111 to an angle of 45°, so that the first bearing plate 111 and the first inner lining plate 211 are in contact; fold the second support plate 122 downward along its outer support crease 34 to an angle of 90°; fold the second support plate 122 upward along the second outer crease 322 between the second support plate 122 and the first bearing plate 111 to an angle of 45°, so that the second support plate 122 and the second inner lining support plate 222 are in contact, and the outer support crease 34 of the second support plate 122 and the inner support crease 35 of the second inner lining support plate 222 are in contact;

[0042] G. As Figure 8 As shown, fold the second bearing plate 112 along the third outer crease 323 between the second bearing plate 112 and the second support plate 122 toward the first inner lining plate 211, so that the second bearing plate 112 and the second inner lining plate 212 are in contact. At this time, the angle between the second bearing plate 112 and the second support plate 122 is 45°. Flip the folded filling buffer plate as a whole so that the second bearing plate 112 is placed below the whole, and the folding is completed. The folded filling buffer plate forms a filling buffer block 4.

[0043] During the folding process, the cut pieces do not need to be adhesively bonded or stapled. The folded filling buffer block 4 has a buffer protection function to withstand a certain amount of pressure and impact, which reduces the manufacturing time of the filling buffer block 4 to a certain extent and lowers the manufacturing cost. The filling buffer block has a simple structure and is flexible to use, and can be used in many scenarios such as item packaging or transportation. Moreover, the filling buffer plate made of corrugated cardboard is recyclable and degradable, which can realize the reuse of resources and is not easy to cause pollution, and has important significance in today's developed logistics. The filling buffer block made of the filling buffer plate has strong reusability. Compared with a folding carton with a buffer function formed integrally, the filling buffer block proposed by the present utility model can strengthen the strength of the cardboard and change the size according to different application scenarios, and can be applied to more scenarios where items need to be protected from impact or pressure. Even, the folding structure of the filling buffer plate proposed by the present utility model can be used to make other buffer protection mechanisms with stronger load-bearing capacity. Its simple structure is conducive to folding and convenient for storage.

[0044] Embodiment Two

[0045] As an implementation method of the present utility model, in Embodiment 2, on the basis of Embodiment 1, the bearing part of the cut piece is continuously extended, and a third support plate, a third bearing plate, a fourth support plate, and a fourth bearing plate are sequentially connected to the end of the second bearing plate, that is, a set of bearing parts in Embodiment 1 is added. During the folding process, after completing Step G in Embodiment 1, Steps E, F, and G can be repeated to fold the third support plate, the third bearing plate, the fourth support plate, and the fourth bearing plate. The filled buffer block after folding has two layers of bearing parts, and its pressure and impact resistance are further improved. In actual application scenarios, according to the specific situation of the packaged item, the number of layers of the bearing part can be added or the cut piece structure in Embodiment 1 can be maintained.
