Description

[Technical Field]

[0001] The present invention relates generally to the field of packaging technology, and more specifically to foldable packaging boxes, foldable packaging box assemblies, and packaging structural members. [Background technology]

[0002] Currently, with the rapid development of e-commerce and offline retail, both consumers and brand owners are increasingly demanding protection and sustainable development of goods. Generally, the packaging of goods needs to achieve good support and cushioning protection of the goods and provide consumers with a good unboxing experience. In offline retail scenarios, it is often necessary to place a single item or multiple items in a fixed position within a gift box. In e-commerce packaging scenarios, when one or multiple items need to be transported in a packaging box, it is expected that individual items be packaged independently of each other to ensure that the goods are not damaged during the transport process, thereby avoiding the effects of interaction between the items and the packaging box or between different items. [Overview of the project] [Problems that the invention aims to solve]

[0003] Conventional packaging methods often utilize pre-formed packaging structural components (e.g., paper or plastic inserts), which are then placed in a packaging box body to achieve the fixed placement of goods within the box. In conventional packaging methods, the packaging structural components and the packaging box body are two separate components that must be operated and assembled separately during use. Given the high demand in e-commerce and the gift box business, it is desirable for packaging structural components and packaging box bodies to have lower manufacturing costs, be made of more environmentally friendly materials, and have structures that can more flexibly accommodate goods of different sizes. Therefore, continuous improvement of packaging structural components and packaging box bodies for goods is currently needed. [Means for solving the problem]

After the at least two collapsible packaging boxes 100 and 100' have been delivered for use, the at least two collapsible packaging boxes 100 and 100' are each unfolded into a three-dimensional state and work together to function as packaging boxes for the arrangement of articles. In a descriptive and exemplary embodiment, one collapsible packaging box 100 uses the most basic configuration of the collapsible packaging box provided by the present disclosure, namely, as shown in Figures 11A to 11C, a collapsible inner packaging structure member 9 and a collapsible outer box body are fixedly joined to form a single unit, the collapsible outer box body including a front panel 11, a left side panel 13, a rear panel 12, and a right side panel 14 connected in order.

Furthermore, as shown in Figure 11D, other foldable packaging boxes 100' may use the same most basic configuration as the foldable packaging box 100 described above, as long as the height of the foldable outer box body is greater than or equal to the height of the foldable inner packaging structure member when the foldable packaging box 100' is in a three-dimensional state (to receive the foldable packaging box 100), or they may use any of the design schemes of the first to fifth exemplary embodiments described above.

[0099] Various exemplary embodiments of foldable inner packaging structural members In the collapsible packaging box provided in this disclosure, the collapsible inner packaging structure member is formed by tessellations of a plurality of hollow tessellation units, the upper and lower ends of each tessellation unit being open and comprising a plurality of walls, at least one of the walls having a height-oriented weakened portion, and the walls being formed of a tearable material.

[0100] Figure 12 is a three-dimensional view of a foldable inner packaging structure member 9 in a foldable packaging box according to an exemplary embodiment of the present disclosure. As shown in Figure 12, the foldable inner packaging structure member 9 of this embodiment is formed by tessellations of a plurality of hollow tessellation units 2.

[0101] The term "tessellation" refers to the joining of one or more planar graphics to cover a surface without leaving gaps between them or overlapping. A "tessellation unit" represents a basic three-dimensional unit consisting of one or more planar graphics, which are connected to each other to form a three-dimensional package. Examples of tessellation units include equilateral triangular tessellation units, square tessellation units, and regular hexagonal tessellation units. In the packaging field, a single regular hexagonal tessellation unit is typically used to be connected to each other to form a honeycomb structure, but as stated above, the tessellation units in this disclosure are not limited to a single regular hexagonal tessellation unit, but may include, for example, equilateral triangular tessellation units, square tessellation units, or other tessellation units, and combinations thereof.

[0102] As shown in Figure 12, each upper end portion 20 of the tessellation unit 2 in this embodiment includes a plurality of walls 23. In this embodiment, the lower end portion 21 is also open, but it should be understood that the lower end portion can be in a closed configuration. In addition, the use of directional terms herein (e.g., upper and lower) corresponds to whether the corresponding directional terms (e.g., usage) can be reversed. An alis 25 is formed where the three walls intersect. In the embodiment shown in Figure 12, each of the tessellation units 2 is configured as a single regular hexagonal tessellation unit or honeycomb unit, and therefore the tessellation unit 2 includes six walls. The plurality of walls form a hollow structure enclosed by the plurality of walls, as a result of substantially saving material while ensuring support function, and the tessellation unit also has good cushioning function when subjected to compression or impact. Furthermore, the hollow structure also allows the tessellation unit to be folded in some cases, thereby facilitating storage and transport. In other words, the hollow structure may allow the foldable inner packaging structural member to be easily switched between the unfolded structure shown in Figure 12 and the folded structure (not shown).

[0103] Furthermore, at least one of the multiple walls 23 of the hollow tessellation unit 2 is provided with a weakened portion arranged in the height direction. In some exemplary embodiments, each of the multiple walls 23 of the hollow tessellation unit 2 is provided with a weakened portion. In other exemplary embodiments of the present disclosure, the packaging structure member further includes a plurality of additional hollow tessellation units (not shown), each of which has an open upper end and includes a plurality of walls, wherein each of the plurality of walls of these additional hollow tessellation units is not provided with a weakened portion in the height direction. That is, in the other exemplary embodiments described above, some hollow tessellation units constituting the packaging structure member are provided with a weakened portion, while other hollow tessellation units constituting the packaging structure member are not provided with a weakened portion.

[0104] The term "weakened portion" refers to a portion of a material that has reduced strength (e.g., tensile or compressive strength) relative to the strength of the rest of the material. When tensile or pressure is applied to the material, stress concentration occurs in the weakened portion, causing fracture or tearing to occur first. In this embodiment, by arranging the weakened portion in the wall, when an article is pressed down from above, the tessellation unit directly below the article is subjected to downward pressure, and the wall below the edge of the article generates tensile force against the unpressed portion, and due to the presence of the weakened portion, the tensile force tears the wall. When the foldable inner packaging structural member is pressed, stress analysis is performed on the tessellation unit and the weakened portion below it.

[0105] In this specification, a weakened portion may further include a cut portion and a tear line, or the weakened portion may be made of a material having a different tear strength than the rest of the wall. The term "cut portion" refers to a portion formed by removing a part of the wall material to reduce its strength. A cut portion may include holes, slits, and the like.

[0106] In this embodiment, the weakened portion is provided with a hole 24. It will be understood that the holes disclosed herein do not necessarily represent circular holes unless explicitly stated otherwise. In this disclosure, holes may include circular holes, elliptical holes, square holes, and the like. In the case of foldable inner packaging structural members, the manufacturing cost is relatively low because they can be easily perforated.

[0107] Figure 13 illustrates a front view of a foldable inner packaging structure member 9 according to one embodiment of the present disclosure, allowing for a clearer view of the distribution of the holes 24. As shown in Figure 13, in this embodiment, a plurality of holes 24 are provided in each of the walls of the tessellation unit, in the height direction of the tessellation unit. In this embodiment, the holes 24 are arranged in all six walls of the tessellation unit, and it should be understood that the holes may be arranged in one or more walls of the tessellation unit as desired.

[0108] The operating principle of the foldable inner packaging structural member 9 for this application will be explained more clearly by referring to the stress analysis diagram of the tessellation unit shown in Figure 14. In Figure 14, a single regular hexagonal tessellation unit, i.e., a honeycomb tessellation unit, is given as an example for analysis.

[0109] In structures formed by tessellation units, one of their primary characteristics is that the structure collapses when subjected to axial loads. As shown in Figure 14, when pressure is applied to the top of a tessellation unit, the tessellation unit tends to fold or collapse. The pressure represented by arrow F in Figure 14 is the downward pressure acting on the ALIS (where the three walls intersect) of the tessellation unit.

[0110] First, we describe the deformation behavior when a force F is applied equally to all tessellation units in Figure 14. At this point, the force F applied to the top of all tessellation units is equal, and when pressure F is initially applied, the upper part of the wall is first crushed and folded, and then the force is transmitted to the middle and lower parts of the wall by the crushed and folded upper part. The stress region of the crushed and folded part of the wall increases due to the crushing and folding, and the crushed and folded part also has a supporting effect, so if the force needs to be transmitted further downwards, a larger force needs to be applied. Therefore, all tessellation units in the same layer are crushed and folded simultaneously. In fact, as the crushing progresses, the rate of increase in the required force also roughly doubles. Each layer of the foldable inner packaging structure, consisting of honeycomb tessellation units, has the same structure and is generally isotropic. Therefore, the foldable inner packaging structure has good structural stability and can generally only be crushed by large forces. Thus, the tessellation structure does not easily deform when the weight of the articles typically used is placed on the honeycomb tessellation units. Consequently, the above structure has excellent pressure resistance and bending resistance.

[0111] Next, the deformation behavior when a pressure F is applied to one or more tessellation units is described. If there is no downward pressure F on adjacent tessellation units, and the wall of the tessellation unit to which pressure F is applied tends to be crushed downward, a relative motion tendency occurs between adjacent alis (e.g., alis 250 and alis 251 shown in Figure 14), and therefore, an unpressed alis 251 experiences a tensile force relative to the pressed alis 250, that is, the wall 230 located below the edge of the article is subjected to a tensile force F1 in the direction away from the pressed alis, as shown in Figure 14. Due to the presence of the tensile force F1, it is more difficult for the tessellation unit to be crushed, and therefore, a foldable inner packaging structure made of honeycomb tessellation units may be suitable for supporting articles of various shapes, regardless of whether the area of ​​the article exceeds or falls below the area occupied by the foldable inner packaging structure.

[0112] In this embodiment, the walls of the tessellation unit are made of a tearable material. For example, paper or aramid paper may be used as the tearable material. When subjected to shear forces, tearable materials can tear; therefore, if pressure is applied to one or more of the tessellation units as described above, the wall 230 between the unpressed alis 251 and the pressed alis 251 may be torn by the shear force. However, since the walls of the tessellation unit typically have a certain supporting function, the tessellation unit is typically crushed before it tears. The walls of the tessellation unit may use a single-layer structure and / or a double-layer structure. For example, using paper for the walls of the tessellation unit, a wall with a single-layer structure is formed by a single layer of paper, and a wall with a double-layer structure is formed by the bonding of two layers of paper. Cutouts may be formed in walls using a single-layer structure, in walls using a double-layer structure, and in both walls using a single-layer structure and walls using a double-layer structure.

[0113] Referring to Figure 14, the compressed tessellation unit tends to move downward, so the tensile force F1 tends to gradually move from the horizontal to the diagonally downward direction. Therefore, a vertical component force is present in the crushing process, and this vertical component force gradually crushes the surrounding uncompressed tessellation units as well, thereby causing the crushing behavior to gradually spread horizontally. Furthermore, in many cases, this horizontally spreading crushing behavior occurs before the wall tears; that is, the crushing spreading behavior occurs before the pressure magnitude required to tear the wall is reached. In other words, a clear tearing region (in the best case, a perfectly vertical tear split is formed) cannot be formed between the pressed and unpressed tessellation units (as used herein, pressed and unpressed refer to whether direct pressure is generated, for example, by an article directly above the tessellation unit), and as a result, the article cannot be smoothly pushed into the foldable inner packaging structure, or even if the article is pushed into the foldable inner packaging structure, the foldable inner packaging structure cannot properly wrap the article. The wrapping behavior will now be described in more detail with reference to Figure 17.

[0114] The applicant found that by providing a weakened portion in the wall of the tessellation unit, when pressure F is applied to the tessellation unit, the wall located below the edge of the article can be easily torn, and as a result, the tessellation unit below the edge of the article can be easily separated from the surrounding tessellation units and then crushed and folded. Furthermore, from an analysis of the crushing behavior of the tessellation unit, it was found that when crushed, stronger support is gradually formed at the bottom of the tessellation unit, and at this point, the crushing behavior that spreads horizontally due to tearing at the weakened portion is prevented, and the surrounding tessellation units form a surrounding structure that can also achieve a good protective effect.

[0115] A tessellation unit according to an embodiment of the present disclosure is described below with reference to Figure 15, which is a top view of a tessellation unit according to an exemplary embodiment of the present disclosure.

[0116] In Figure 15, the bolded areas represent compressed tessellation units, and the compressed tessellation units shown in Figure 15 are torn from the surrounding tessellation units. As shown in Figure 15, due to the presence of weakened areas, these areas form stress concentration points, and when force is applied, tearing occurs easily. As a result, the compressed tessellation unit is easily torn from adjacent tessellation units, and eventually, the tessellation units below the compressed area shown in Figure 15 are completely torn from adjacent tessellation units.

[0117] Figure 16 is a schematic diagram of the use of a foldable inner packaging structure member according to an exemplary embodiment of the present disclosure. As shown in Figure 16, when an article is placed in the foldable inner packaging structure member of this embodiment and pressure is then applied, the article pushes down the tessellation unit located beneath it, and the tessellation unit located beneath the article is crushed as a result of the pressure. Furthermore, due to the presence of a weakened portion, the wall of the tessellation unit beneath the edge of the article is torn away from the weakened portion of the wall. With further pressing of the article or an increase in the crushing depth, the wall of the tessellation unit directly beneath the article is crushed and folded, and due to the increased area of ​​the crushed and folded wall and the stacking effect, the force required to further crush the crushed and folded wall gradually increases, and thus a good support effect can be achieved. Furthermore, since tearing of the weakened portion avoids horizontal crushing, the original shape of the tessellation unit separated from the crushed tessellation unit is still maintained due to the structural stability of the tessellation unit itself, thereby forming a containment space that is substantially the same shape as the shape of the article for enclosing the article. Thus, good packaging of the article can be formed.

[0118] From the above description, it can be seen that in this embodiment, when pressed vertically by the tessellation structure, the tessellation structure is crushed vertically to form a recess for accommodating the product. Furthermore, by setting weakened areas in the walls of the tessellation structure, crushing of the tessellation structure that spreads horizontally is avoided, and as a result, a clear tearing region exists between the pressed and unpressed tessellation units, thereby achieving good encasing of the article.

[0119] Honeycomb tessellation structures or honeycomb cardboard are typically used to support articles, and the applicant, through theoretical analysis and experimental verification (experiments described in detail below), has first found that articles can be wrapped or packaged using honeycomb tessellation structures and honeycomb cardboard. In addition, as described above, since the tessellation structure is compressed vertically, articles can be pressed into the honeycomb tessellation structure, and the bottom of the tessellation structure still has good support. Due to the setting of weakened portions, the compression of the tessellation structure that spreads horizontally is avoided, and therefore a very good wrapping effect can be achieved for articles. Furthermore, the honeycomb tessellation structure in the embodiments of this disclosure has a simple configuration, is easy to manufacture, and is very convenient to use. Articles only need to be pressed into the honeycomb tessellation structure, there are no restrictions on the shape of the articles, and after different articles have been pressed in, the uncompressed tessellation units separate the articles, thereby providing independent protection for the articles.

[0120] Returning to Figures 12 and 13, we can see that in this embodiment, multiple holes 24 are provided, forming a gradient arrangement in the height direction of each section of the wall. Specifically, the size of the holes gradually decreases from the upper end to the lower end of the wall. Larger holes mean lower strength, i.e., easier tearing. Therefore, holes with a gradient decreasing in size in the height direction mean that the crushing and tearing forces of each layer of the tessellation unit also increase in a gradient. Thus, under the same pressure, the upper tessellation units will be crushed more easily first, while the lower tessellation units that are crushed will require a greater force afterward. Therefore, when an article is pushed down, the upper part of the tessellation unit that first contacts the article is crushed first and is also more easily torn and separated from the surrounding tessellation units. As crushing progresses, the crushed tessellation units also fold and combine with the smaller holes below, requiring a greater force to crush the lower tessellation units. Therefore, the graduated holes can more effectively create layer-by-layer or gradual crushing effects in the height direction, thereby avoiding simultaneous or premature deformation of other parts that would affect the overall effect during the process of pressing articles into the foldable inner packaging structure.

[0121] In this embodiment, the sloping holes are arranged vertically from the upper end of the wall, but do not extend to the entire height of the wall, i.e., they do not extend completely to the lower end of the wall. This is not a limitation, and it will be understood that the size, spacing, and extension distance of the holes can be set as needed. In this embodiment, the holes are arranged approximately midway along the width of the wall. It will be understood that the holes can also be arranged near any Alice position along the width of the wall.

[0122] The following experiments will further investigate the effects of factors such as hole spacing, hole shape, paper weight, and side length of the honeycomb hexagonal structure on the packaging of goods.

[0123] First, several foldable inner packaging structural members are prepared for a quasi-static compression test. In this embodiment, the foldable inner packaging structural members utilize a honeycomb structure. For the quasi-static compression test, a box compression tester GK-KY25 (commercially available from Suzhou Sushi Testing Group Co., Ltd.) was used, with a compression speed of 1 mm / min. The criterion for determining the end of compression depth was the complete indentation of the article into the honeycomb structure (at this point, the corresponding stress increased sharply). The article is a perfect cylinder with a height of approximately 60 mm and a diameter of approximately 60 mm. Basic information for each sample is shown in Table 1 below.

[0124] [Table 1]

[0125] First, the parameter information is explained below.

[0126] Regarding sample size, it represents the length, width, and height of the foldable inner packaging structure member. Regarding unit arrangement, it represents the number of units arranged vertically and the number of units arranged horizontally. Regarding unit side length, it represents the length of the sides of the hexagons in the honeycomb structure. Regarding maximum and minimum hole diameter, they represent the maximum and minimum sizes of the holes in the longitudinal direction. For example, if the holes are circular, the maximum hole diameter represents the maximum diameter of the hole, and the minimum hole diameter represents the minimum diameter of the hole. If the holes are elliptical, the maximum hole diameter represents the maximum diameter of the hole on the major axis, and the minimum hole diameter represents the minimum diameter of the hole on the major axis. Regarding hole spacing, it represents the spacing between adjacent edges of adjacent holes in the vertical direction. Regarding paper basis weight, it represents the basis weight of the paper constituting the honeycomb structure. Furthermore, it should be noted that the above comparisons between samples should be understood not as comparisons with prior art, but as comparisons between different embodiments of this application, and the following experimental comparisons should also be understood in the same way.

[0127] 1. First, we consider the effect of the unit edges. The length of the unit edges of the honeycomb structure mainly affects the degree of compression of the enclosed article. The shorter the unit edge length, the better the effect on the enclosed article. Figure 6 shows a top view of the honeycomb structure, with the shaded area being the honeycomb unit located beneath the tested article.

[0128] In the ideal case, we can see that the top-down area of ​​the article under test is set to S, the number of honeycomb units completely located directly beneath the article under test is m, and the number of honeycomb units covered by the edges of the article under test is n. When the article is compressed into the honeycomb structure, as described above, the walls of the honeycomb units located beneath the edges of the article are torn apart. Thus, the number of honeycomb units that are crushed and torn apart is (m+n), and the area of ​​these honeycomb units may be expressed as S1, i.e., S1 = (m+n) × S honeycomb units. α = S / SS1 may be defined to represent the degree of compression of the article being wrapped, and furthermore, the length of the unit side of the honeycomb unit is defined as l, and according to a simple geometric relationship, we can obtain the following:

[0129]

number

[0130] Clearly, the smaller l is, the larger α is, and the greater the degree of constriction of the wrapped article, i.e., the better the wrapping effect. However, l should not be too small. If l is too small, it becomes difficult to create the honeycomb structure. Specifically, for example, if l is less than 4 mm, the tensile force during the creation process will be greater than the interlayer bonding force that the paper can withstand, causing the paper to break.

[0131] Therefore, based on theoretical derivation and testing, it is appropriate to set the unit side length in the range of 5 to 12 mm. Preferably, the unit side length may be set to 10 mm. In all of the above samples, 10 mm (including or excluding the range) is adopted as the unit side length.

[0132] Furthermore, it should be understood that this disclosure is not limited to a side length of 10 mm, and other appropriate unit side lengths may be used depending on the actual situation, as long as they do not contradict the above theory of this disclosure.

[0133] 2. The effects of hole size and spacing, and paper basis weight on crushing and tearing behavior are further discussed below. Hole size and spacing, and paper basis weight can all affect the ease of crushing the honeycomb structure, and therefore, these three factors together determine the ease of crushing the honeycomb structure. As mentioned above, in this disclosure, the packaging of an article is implemented by slicing bilayer crushing or stepwise crushing of the honeycomb unit beneath the article, and tearing of the wall beneath the edge of the article (or between the honeycomb unit beneath the edge of the article and the adjacent honeycomb unit). Larger hole sizes reduce the strength of the honeycomb unit and make it more susceptible to tearing. Smaller hole sizes improve the strength of the honeycomb unit and make it less susceptible to tearing. Larger hole spacing improves the strength of the honeycomb unit and makes it less susceptible to tearing. Smaller hole spacing reduces the strength of the honeycomb unit and makes it more susceptible to tearing. The lower the basis weight of the paper, the weaker the honeycomb unit becomes, making it more susceptible to both tearing and crushing. The higher the basis weight of the paper, the stronger the honeycomb unit becomes, making it less susceptible to both tearing and crushing. Therefore, to ensure the occurrence of tearing and crushing, the hole size must not be too small, the hole spacing must not be too large, and the paper basis weight must not be too high. Otherwise, crushing will be difficult to occur, and more importantly, a crushed honeycomb unit will be difficult to tear. This can result in the honeycomb structure as a whole being crushed even when the paper is not torn (i.e., it may not produce a crushing effect on each layer), causing the honeycomb units on the outside of the article to deform as well, meaning that the horizontal spread of the crushing behavior replaces the tearing behavior. However, at the same time, to ensure the most basic support function, the hole size must not be too large, the hole spacing must not be too narrow, and the paper basis weight must not be too low.

[0134] First, compare the test results of Sample A and Sample C in Table 1. For Sample A and Sample C, all other conditions were the same except for the minimum pore diameter and pore spacing. Specifically, the pore spacing in Sample A was set to 7 mm, while the pore spacing in Sample C was set to a larger size of 14 mm. From the test results, in Sample A, the article could be smoothly pushed into the honeycomb structure, whereas in Sample C, it was difficult to press the article against the honeycomb structure. Therefore, it can be seen that if the pore spacing is too large, it becomes difficult to cause tearing behavior.

[0135] Further compare the test results of Sample A and Sample B. For Sample A and Sample B, all other conditions were the same except for the pore shape and the maximum pore diameter. Specifically, the pore shape of Sample A was circular and the maximum pore diameter was 4.5 mm, while the pore shape of Sample B was elliptical and the maximum pore diameter was 5 mm. As a result of the test, it was found that both Sample A and Sample B could cause good crushing and tearing behavior.

[0136] Next, further compare Sample D and Sample E. For Sample D and Sample E, all other conditions were the same except for the basis weight of the paper. Specifically, the basis weight of the paper in Sample D was 110 g / m 2 while the basis weight of the paper in Sample E was 170 g / m 2 As a result of the test, when other conditions were appropriate, it was found that both the paper with a basis weight of 110 g / m 2 and the paper with a basis weight of 170 g / m 2 could cause good crushing and tearing behavior.

[0137] As shown above, only five representative samples are listed for data comparison. After a series of theoretical inferences and experimental comparisons, the applicant found the following parameter settings. The basis weight range of the paper can be set to 110 - 170 g / m 2 Furthermore, the basis weight range of the paper can be set to 110 - 140 g / m 2The following can be set: The length of the unit side of the honeycomb unit can be set to 5-12 mm, optionally 6-15 mm, optionally 7-14 mm, and optionally 8-12 mm. If the length of the unit side of the honeycomb unit is 5 mm, the hole gradient diameter range (i.e., the maximum and minimum hole diameters that decrease in the height direction) can be set to 1-2.5 mm. If the length of the side of the honeycomb unit is 12 mm, the hole gradient diameter range can be set to 2-5 mm. The spacing between the edges of adjacent holes can be set to 10-200% of the maximum hole diameter.

[0138] Next, we will further investigate, through experiments, the uniformity of the holes, the relationship between the maximum hole diameter and the length of the unit side, and the influence of the number of perforated walls on the packaging of the goods.

[0139] Similar to the previous test, several foldable inner packaging structural members were first prepared to conduct a quasi-static compression test. In this embodiment, the foldable inner packaging structural members were of a honeycomb structure. A box compression tester GK-KY25 (commercially available from Suzhou Sushi Testing Group Co., Ltd.) was used in the test, the compression speed was 1 mm / min, and the criterion for determining the end of compression depth was when the article was completely pushed into the honeycomb structure (at this point, the corresponding stress increased sharply). The article was a perfect cylinder with a height of approximately 60 mm and a diameter of approximately 60 mm. Basic information for each sample is shown in Table 2 below.

[0140] [Table 2]

[0141] The same parameters shown in Tables 2 and 1 have the same meaning and will not be described again in this specification. In addition, in the case of the relationship between the maximum hole diameter and the minimum hole diameter, using sample F as an example, if the maximum hole diameter and the minimum hole diameter are the same, it indicates that the size of the holes in the walls is the same, i.e., holes of the same size are provided. The number of perforated walls is the number of walls with holes among the six walls of the honeycomb unit.

[0142] First, we compare samples F and G. Sample F had holes of the same size, while sample G had holes arranged in a gradient. In particular, the size of the holes in the wall in the height direction gradually decreases from the top to the bottom. When comparing the two, we found that in sample F, when the sample was pressed in, the honeycomb unit at the bottom also experienced a crushing phenomenon. In contrast, by arranging the holes in sample G in a gradient, the honeycomb unit at the bottom did not experience a crushing phenomenon. Combined with the above analysis, it can be seen that the gradient-arranged holes can more effectively generate a layer-by-layer crushing effect in the height direction, thereby avoiding the occurrence of a crushing phenomenon at the bottom when an article is pressed into the honeycomb structure, and thus affecting the overall effect.

[0143] Next, we compared sample H and sample I. For both sample H and sample I, all other conditions were the same except for the maximum and minimum hole diameters (or hole diameter gradient range). Specifically, the hole diameter gradient range for sample H was 4.5 to 2 mm, while the hole diameter gradient range for sample I was 3 to 0.5 mm. Comparing the two, both sample H and sample I were able to produce crushing and tearing behavior, but sample H also produced a specific collapse phenomenon with honeycomb units around the article; that is, the crushing behavior had a small horizontal spread, resulting in insufficient enveloping effect after the article was pressed into sample H. However, since there was no horizontal spread of crushing in sample I, the enveloping effect after the article was pressed into sample I was better.

[0144] Finally, we compared sample J and sample K. All other conditions were the same for both sample J and sample K, except for the number of perforated walls. Specifically, six holes were formed in sample J, while only two holes were formed in sample K. Comparing the two, both sample J and sample K were able to exhibit crushing and tearing behavior. However, sample J showed collapse of the honeycomb unit around the article, and the tearing behavior of the non-perforated walls was also insufficient. This indicates that the crushing behavior of sample J spread horizontally, resulting in an insufficient enveloping effect after the article was pressed into sample J. However, sample K did not exhibit horizontal crushing, and because it had holes in six walls, the tearing behavior was also good, resulting in a better enveloping effect of the article after it was pressed into sample K.

[0145] As can be seen from the experimental comparison in Table 2, the crushing behavior of holes arranged in a gradient is superior to that of uniformly distributed holes, and the holes arranged in a gradient can produce good layer-by-layer crushing behavior, which is consistent with the analysis above. In addition, the applicant found through testing that when the maximum hole diameter is less than 30% of the length of the unit side of the honeycomb unit, horizontal crushing spreads easily occur, resulting in the honeycomb unit around the article being easily deformed and resulting in insufficient wrapping. When the maximum hole diameter is greater than 40% of the length of the unit side of the honeycomb unit, the spread of horizontal crushing can be well reduced. In addition, the more perforated walls there are, the more easily crushing and tearing behavior occurs, and the easier it is to prevent the spread of horizontal crushing. Therefore, in this disclosure, the maximum hole diameter is set to greater than 40% of the length of the unit side of the honeycomb unit. Furthermore, it is preferable that the holes are provided in six walls.

[0146] In addition, in this embodiment, since the honeycomb unit is formed from a paper-based tearable material, the overall structure is 100% green and recyclable. Furthermore, because the paper-based tearable material is not elastic, it can form a permanent structure for protecting articles, and as a result, the corresponding protection can be provided to the articles more effectively.

[0147] Next, a description of a foldable inner packaging structure member in a foldable packaging box according to another exemplary embodiment of the present disclosure will be provided. The basic configuration and operation of the foldable inner packaging structure member in this other embodiment are the same as the basic configuration and operation of the foldable inner packaging structure member in the above-described embodiment. Therefore, the description of components in the foldable inner packaging structure member in this other exemplary embodiment that have the same function and configuration as the components of the foldable inner packaging structure member in the above-described exemplary embodiment will be omitted.

[0148] Figure 18 shows another exemplary embodiment of the foldable inner packaging structure member 9 in a foldable packaging box according to the present disclosure. As shown in Figure 18, the main difference between this other exemplary embodiment and the previously described exemplary embodiment is that a bottom support member 7 is provided at the bottom of the foldable inner packaging structure member 9. The bottom support member 7 is flat and is removablely attached to the bottom of the foldable inner packaging structure member 9, for example, by adhesive. When in use, the foldable inner packaging structure member 9 is placed on the ground by the bottom support member 7, thereby increasing the contact area with the ground and resulting in a better support effect. If the foldable inner packaging structure member needs to be folded for transport, for example, the bottom support member 7 can be separated from the foldable inner packaging structure member 9 and attached to the bottom of the foldable inner packaging structure member 9 when in use.

[0149] As can be seen above, the foldable inner packaging structural members provided by one or more embodiments of the present disclosure are honeycomb structures formed by tessellations of a plurality of hollow honeycomb units, each of which has an open upper and lower end portion and includes six walls, the six walls being made of paper and having a plurality of holes having a size that gradually decreases downward in the height direction from the upper end portion of the tessellation unit. The honeycomb structure can have a certain degree of support effect and ensures that it can produce a crushing behavior when pressed. The walls are made of paper, thereby ensuring that the walls can produce a tearing behavior when subjected to tensile force. The setting of the holes ensures that the walls are torn more easily at the holes. Furthermore, the sloping arrangement of the holes ensures the occurrence of layer-by-layer crushing and tearing behavior, thereby reducing or avoiding the spread of crushing in the horizontal direction.

[0150] According to alternative embodiments of the present disclosure, as shown in Figure 19A, the present disclosure provides another foldable inner packaging structure member 9 that is arranged in a different direction (i.e., perpendicular to the arrangement direction in Figure 16) compared to the embodiment shown in Figure 16, wherein at least one other wall 23 of the plurality of walls 23 of the plurality of hollow tessellation units 2 is provided with a lateral weakening portion 80. For example, the wall provided with the lateral weakening portion 80 may be a wall forming a hollow tessellation unit 2 located on the periphery side of the plurality of hollow tessellation units 2. According to some embodiments, the lateral weakening portion 80 may be configured as at least one lateral tangent 80 arranged perpendicular to the height direction. In the embodiment shown in Figure 19A, the lateral tangent 80 traverses all of the plurality of hollow tessellation units 2 of the packaging structure member 9 in a direction perpendicular to the height direction of the tessellation units, i.e., at least one wall in each of the three layers of the hollow tessellation units shown in the figure is tangent to the lateral tangent. As shown in Figure 19B, in an example of a foldable packaging box including a foldable outer box body 10 and a packaging structural member 2 as shown in Figure 19A, when an article P is placed on the packaging structural member 2 and pressure is then applied, the article pushes down the tessellation unit located beneath it, and the tessellation unit located beneath the article is crushed as a result of the pressure. In embodiments not shown, the lateral tangent 80 cannot traverse all of the tessellation unit 2 in a direction perpendicular to the height direction of the tessellation unit, for example, traversing only 50% of the tessellation unit, and the remaining 50% of the walls of the tessellation unit do not have a lateral tangent; that is, assuming there are a total of 10 layers of tessellation units, the lateral tangent 80 cuts through 5 layers of the walls of the tessellation unit 2 only in a direction perpendicular to the height direction of the tessellation unit, and not through the remaining 5 layers of the walls of the tessellation unit 2. In this way, when an article is pressed into the packaging structure along the lateral tangent, the upper five layers of tessellation units are compressed, but the lower five layers of tessellation units are not, thereby providing good cushioning properties for protecting the article from packaging.It should be noted that the configuration of the foldable inner packaging structure member 9 shown in Figures 19A and 19B in the alternative embodiment can also be incorporated into the various exemplary embodiments shown in Figures 1 to 18, provided that there is no structural and / or functional inconsistency. For example, in the combination scheme, the tessellation unit 2 located in the center of the inner packaging structure member 9 may use the cut-out design described in the various exemplary embodiments shown in Figures 1 to 18, while the tessellation unit 2 located on the periphery may use the lateral tangential design described in the alternative embodiment shown in Figures 19A and 19B.

[0151] The sizes and values ​​described herein should not be understood as being strictly limited to the exact numerical values ​​listed. Conversely, unless otherwise stated, each size is intended to mean the listed value and a functionally equivalent range around that value. For example, a size disclosed as "10mm" is intended to mean "approximately 10mm".

[0152] While several embodiments of this disclosure are shown and illustrated, those skilled in the art will understand that these embodiments may be modified without departing from the principles and spirit of this disclosure, and that the scope of this disclosure is defined by the claims and their equivalents.
