Description

TECHNICAL FIELD The present disclosure relates generally to the technical field of packaging, and more particularly to a foldable packaging box, a foldable packaging box assembly, and a packaging structural member. BACKGROUND Currently, with the rapid development of e-commerce and the offline retail business, both consumers and brand owners are demanding more from item protection and sustainable development. In general, packaging of an item is required to achieve good support and cushioning protection of the item, and provides consumers with a good opening experience. In an offline retail scenario, a single item or multiple items often need to be placed in fixed positions in a gift box. In an e-commerce packaging scenario, when an item or multiple items need to be transported in a packaging box, in order to ensure that the items are not damaged in the process of transportation, it is expected that individual items are packaged independent of each other to avoid the effect of interactions between the items and the packaging box or between different items. Traditional packaging forms are often implemented by using a preformed packaging structural member (e.g., a paper insert or a plastic insert), and then placing the formed packaging structural member into a packaging box body to achieve the fixed placement of items in the packaging box by using the packaging structural member. In the traditional packaging forms, the packaging structural member and the packaging box body are two components that are separated from each other and need to be separately operated and assembled when in use. Considering the high demand of e-commerce and gift box businesses, it is desirable that packaging structural members and packaging box bodies have low manufacturing costs, more environmentally friendly materials, and structures that more flexibly suit items of different sizes. Therefore, there is currently a need for continuous improvement of packaging structural members and packaging box bodies for items.

Various Exemplary Embodiments of Foldable Inner Packaging Structural Members In the foldable packaging box provided by the present disclosure, the foldable inner packaging structural member is formed by tessellation of a plurality of hollow tessellation units, an upper end portion and a lower end portion of each of the tessellation units being open and including a plurality of walls, wherein at least one wall among the plurality of walls is provided with a weakened portion arranged in the height direction, and the walls are formed from a tearable material. FIG. 12 is a stereo view of a foldable inner packaging structural member 9 in a foldable packaging box according to an exemplary embodiment of the present disclosure. As shown in FIG. 12, the foldable inner packaging structural member 9 of the present embodiment is formed by tessellation of a plurality of hollow tessellation units 2. The term “tessellation” means that one or more planar graphics are spliced to cover a surface without leaving voids therebetween and overlapping. The “tessellation unit” represents a basic three-dimensional unit composed of one or more planar graphics, and these basic three-dimensional units are connected to each other to form a three-dimensional package. The tessellation units may include, for example, equilateral triangular tessellation units, equilateral quadrilateral tessellation units, orthohexagonal tessellation units, and the like. In the field of packaging, single orthohexagonal tessellation units are typically employed to be connected to each other to form a honeycomb structure, but it should be understood that, as described above, the tessellation units in the present disclosure are not limited to the single orthohexagonal tessellation units, but may include, for example, equilateral triangular tessellation units, equilateral quadrilateral tessellation units, or other tessellation units and combinations thereof. As described in FIG. 12, the upper end portion 20 of each of the tessellation units 2 in the present embodiment includes a plurality of walls 23. In the present embodiment, the lower end portion 21 is also open, and it should be understood that the lower end portion may be configured to be closed. In addition, the use of directional terms (such as upper and lower) herein is corresponding, depending on whether the corresponding directional terms, such as usage status, can be reversed. An arris 25 is formed where three walls meet. In the embodiment shown in FIG. 12, each of the tessellation units 2 is set to be a single orthohexagonal tessellation unit or a honeycomb unit, so the tessellation unit 2 includes six walls. By means of a plurality of walls, the tessellation unit forms a hollow structure surrounded by the plurality of walls so that materials can be substantially conserved while a support function is guaranteed, and the tessellation unit when being squeezed or impacted also has a good cushioning function. Furthermore, the hollow structure also enables the tessellation unit to be capable of being folded in some cases, thereby facilitating storage and transportation. In other words, the hollow structure may allow the foldable inner packaging structural member to be easily switched between an unfolded structure shown in FIG. 12 and a folded structure not shown. Furthermore, at least one wall among the plurality of 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 plurality of walls 23 of the hollow tessellation unit 2 is provided with the weakened portion. In other exemplary embodiments of the present disclosure, the packaging structural member further includes a plurality of additional hollow tessellation units (not shown), an upper end portion of each of these additional hollow tessellation units being open and including a plurality of walls, wherein each of the plurality of walls of the plurality of these additional hollow tessellation units is not provided with a weakened portion in the height direction. That is, in the foregoing other exemplary embodiments, some hollow tessellation units constituting the packaging structural member are provided with the weakened portion, and other hollow tessellation units constituting the packaging structural member are not provided with the weakened portion. The term “weakened portion” refers to a portion having a strength (e.g., tensile strength or compressive strength) that has been attenuated relative to that of the remaining portion. When a tensile force or pressure is exerted on a material, since stress concentration occurs at the weakened portion, fracture or tearing is first performed at the weakened portion. In the present embodiment, by disposing the weakened portion on the wall, when an item is pushed down from the top, the tessellation units directly below the item will be subjected to downward pressure, and the wall below the edge of the item will produce a tensile force relative to unpressed portions, and due to the presence of the weakened portion, the tensile force will cause the wall to be tom. Stress analysis will be carried out on the tessellation units and the weakened portions below when the foldable inner packaging structural member is pressed. Herein, the weakened portion may further include an excision portion and the tear line, or the weakened portion is made of a material having a tear strength different from that of the remaining portions of the wall. The term “excision portion” refers to a portion formed by removing part of the material of the wall to reduce the strength thereof. The excision portion may include holes, slits, and the like. In the present embodiment, the weakened portion is set to be a hole 24. It will be appreciated that the hole disclosed herein does not certainly represent a circular hole, unless expressly stated to be a circular hole. In the present disclosure, the hole may include circular holes, oval holes, square holes, and the like. For the foldable inner packaging structural member, it can be easily perforated, so manufacturing costs are relatively low. FIG. 13 illustrates a front view of the foldable inner packaging structural member 9 according to an exemplary embodiment of the present disclosure, from which the distribution of the holes 24 can be seen more clearly. As shown in FIG. 13, in the present embodiment, a plurality of holes 24 are provided on each of the walls of each of the tessellation units in the height direction of the tessellation unit. In the present embodiment, the holes 24 are disposed on all six walls of the tessellation unit, and it should be understood that the holes may be disposed on one or more walls of the tessellation unit as desired. The working principle of the foldable inner packaging structural member 9 of the present application will be explained more clearly with reference to a stress analysis diagram of the tessellation unit shown in FIG. 14. In FIG. 14, a single orthohexagonal tessellation unit, i.e., a honeycomb tessellation unit, is taken as an example for analysis. For a structure formed by the tessellation units, one of its major characteristics is that the structure will be crushed when bearing an axial load. As shown in FIG. 14, when pressure is exerted on the top of the tessellation unit, the tessellation unit will have a tendency to be folded down or crushed. Pressure represented by arrow F in FIG. 14 is downward pressure acting on the arris (where the three walls meet) of the tessellation unit. First, a deformation behavior when the force F is uniformly applied to all of the tessellation units in FIG. 14 will be described. At this point, the force F on the tops of all of the tessellation units is uniform, and when the pressure F is initially applied, the upper portion of the wall will be crushed and folded first, and then the force will be transmitted to the middle and lower portions of the wall by the crushed and folded upper portion. A stressed area of the crushed and folded portion of the wall is increased due to crushing and folding, and the crushed and folded portion also has the effect of supporting, so that if the force needs to be further transmitted downward, greater force needs to be applied. As such, all of the tessellation units of the same layer are synchronously crushed and folded. In effect, as the crushing progresses, the rate of increase in the force required is also almost doubled. Since each layer of the foldable inner packaging structural member composed of the honeycomb tessellation units has the same structure and is approximately isotropic, the foldable inner packaging structural member has good structural stability, and generally can only be crushed by great force, so the tessellation structure is not easily deformed when the weight of commonly used items is placed on the honeycomb tessellation unite. Therefore, the structure described above has superior resistance to pressure and superior good bending resistance. Next, a deformation behavior when the pressure F is applied on one or more of the tessellation units will be described. Since there is no downward pressure F on adjacent tessellation units, when the walls of the tessellation units on which the pressure F is applied have a tendency to be crushed downward, a relative motion tendency is produced between adjacent arrises (e.g., arris 250 and arris 251 shown in FIG. 14), so the unpressed arris 251 produces a tensile force against the pressed arris 250, i.e., the wall 230 located below an edge of an item is subjected to a tensile force Fl in the direction away from a pressed arris as shown in FIG. 14. Due to the presence of the tensile force Fl, it is more difficult for the tessellation units to be crushed, therefore, the foldable inner packaging structural member composed of the honeycomb tessellation units may be suitable for supporting items of various shapes, whether the areas of the items are greater than or less than the occupied area of the foldable inner packaging structural member. In the present embodiment, the walls of the tessellation units are made of a tearable material. With regard to the tearable material, paper or aramid paper may be used, for example. The tearable material when being subjected to a shear force will likely tear, therefore, there is a possibility that the wall 230 between the unpressed arris 251 and the pressed arris 251 will be tom by the shear force when pressure is applied on one or more of the tessellation units as described above. However, since the walls of the tessellation unit typically have a certain support function, the tessellation unit typically has been crushed before being tom. The walls of the tessellation unit may employ a single-layer structure and / or a dual-layer structure. Using the use of paper for the walls of the tessellation unit as an example, walls having the single-layer structure are formed by a layer of paper, and walls having the dual-layer structure are formed by the adhesion of two layers of paper. The excision portions may be formed on the walls employing the single-layer structure, may also be formed on the walls employing the dual-layer structure, and further may be formed on both the walls employing the single-layer structure and the walls employing the dual-layer structure. With reference to FIG. 14, since the pressed tessellation unit produces a tendency to move downward, the tensile force Fl gradually tends to be from the horizontal direction to an obliquely downward direction, and therefore, a vertical component force will be present in a crushing process, and the vertical component force will cause surrounding unpressed tessellation units to also be gradually crushed, thereby causing the crushing behavior to gradually spread in the horizontal direction. Moreover, in many cases, such crushing behavior spreading in the horizontal direction occurs prior to tearing of the wall, i.e., the crushing spreading behavior has occurred before a magnitude of pressure that causes the wall to tear is reached. That is, no obvious tear area (in the best case, a fully vertical tear split is formed) can be formed between a pressed tessellation unit and an unpressed tessellation unit (pressed and unpressed herein refer to whether direct pressure is produced by, for example, an item, etc., directly above the tessellation unit), so that the item cannot be smoothly pressed into the foldable inner packaging structural member, or even if the item is pressed into the foldable inner packaging structural member, the foldable inner packaging structural member cannot wrap the item well. Next, a wrapping behavior will be described in more detail with reference to FIG. 17. The applicant found that by providing the weakened portion on the wall of the tessellation unit, the walls located below edges of an item can be easily tom when the pressure F is applied on the tessellation unit, so that the tessellation units below the edges of the item are easily separated from the surrounding tessellation units and then are crushed and folded. Moreover, from the analysis on the crushing behavior of the tessellation unit, it can be seen that stronger support will gradually form at the bottom of the tessellation unit when being crushed, and at this point, due to the occurrence of tearing at the weakened portion, the crushing behavior spreading in the horizontal direction is prevented, and the surrounding tessellation units will form an encircling structure that can also achieve a good protective effect. A tessellation unit according to an embodiment of the present disclosure will be described below with reference to FIG. 15, which is a top plan schematic view of the tessellation unit according to an exemplary embodiment of the present disclosure. In FIG. 15, bold portions represent pressed tessellation units, and the pressed tessellation units shown in FIG. 15 have been tom apart from the surrounding tessellation units. As shown in FIG. 15, due to the presence of the weakened portion, the weakened portion will form a stress concentration point, and tearing will easily be produced when a force is applied, so that the pressed tessellation units are easily tom apart from the adjacent tessellation units, ultimately causing the tessellation units below a pressed area shown in FIG. 15 to be completely tom apart from the adjacent tessellation units. FIG. 16 is a schematic diagram of use of a foldable inner packaging structural member according to an exemplary embodiment of the present disclosure. As shown in FIG. 16, when an item is placed on the foldable inner packaging structural member of the present embodiment and then pressure is applied, the item will press down the tessellation units located below same, and then the tessellation units located below the item will be crushed as a result of the pressure. Moreover, due to the presence of the weakened portions, the walls of the tessellation units below the edges of the item will be tom from the weakened portions of the walls. With the further pressing of the item or the increase in the crushing depth, the walls of the tessellation units directly below the item will be crushed and folded, and due to increased areas of the crushed and folded walls and a stacking effect, force required for further crashing the crashed and folded walls gradually increases, and thus a good support effect can be achieved. Moreover, since tearing of the weakened portions avoids crashing spreading in the horizontal direction, the original shape of the tessellation unit separated from the crashed tessellation unit will still be maintained due to the structural stability of the tessellation unit itself, thereby forming an accommodating space in a shape substantially similar to that of the item to wrap the item. Thus, good packaging of the item can be formed. From the above description, it can be seen that in the present embodiment, by means of the tessellation structure, the tessellation structure, when being pressed in the vertical direction, is crushed in the vertical direction to form a recessed portion for accommodating a product. Moreover, due to the setting of the weakened portion on the wall of the tessellation structure, the crushing of the tessellation structure spreading in the horizontal direction is avoided, so that there will be a clear tear area between the pressed and unpressed tessellation units, thereby achieving good wrapping of the item. A honeycomb tessellation structure or honeycomb cardboard is typically used tn support an item, and the applicant first found, by means of theoretical analysis and experimental validation (experiments will be described in detail below), that the item can be wrapped or packaged using the honeycomb tessellation structure and the honeycomb cardboard. Additionally, as described above, since the tessellation structure is crushed in the vertical direction, the item can be pressed into the honeycomb tessellation structure, and then the bottom of the tessellation structure still has good support. Due to the setting of the weakened portion, the crushing of the tessellation structure spreading in the horizontal direction is avoided, therefore, an extremely good wrapping effect can be achieved for the item. Furthermore, the honeycomb tessellation structure in the embodiment of the present disclosure has a simple configuration, is easy to manufacture, and is extremely convenient to use. It is only necessary to press an item into the honeycomb tessellation structure, there is no limit to the shape of the item, and after different items are pressed in, the unpressed tessellation units separate the items, which can provide independent protection for the items. Returning again to FIG. 12 and FIG. 13, it can be seen that in the present embodiment, a plurality of holes 24 are provided and form a gradient arrangement in the height direction of each of the walls. Specifically, the sizes of the holes gradually decrease from the upper end portion to the lower end portion of the wall. A larger-sized hole means that there is a lower strength here, i.e., tearing is more likely to occur. Therefore, the holes having sizes that decrease in a gradient in the height direction means that a crushing force and a tearing force of each layer of the tessellation units also increase in a gradient. Therefore, under the action of the same pressure, upper tessellation units will be more easily crushed first, while lower tessellation units being crushed would require subsequent greater force. Therefore, when an item is pressed down, upper portions of the tessellation units in contact with the item first are crushed first and are also more easily tom and separated from the surrounding tessellation units. As the crushing progresses, the tessellation units that have been crushed will also be folded up, and combined with smaller-sized holes below, cause greater force to be required to crush the lower tessellation units. Accordingly, by means of the holes arranged in a gradient, a layer-by-layer crushing or progressive crushing effect in the height direction can be produced more effectively, thereby avoiding the simultaneous or first creation of deformation of other parts affecting the overall effect in a process of pressing an item into the foldable inner packaging structural member. In the present embodiment, the holes arranged in a gradient are disposed from the upper end portion of the wall in the height direction, but do not extend to the height of the entire wall, i.e., do not extend completely to the lower end portion of the wall. It will be appreciated that this does not constitute a limitation, and the size, spacing, and extension distance of the holes may be set as needed. In the present embodiment, the holes are disposed at approximately intermediate positions in the width direction of the wall. It will be appreciated that the holes can also be disposed closer to the position of any arris in the width direction of the wall. The effects of the spacing of the holes, the shape of the holes, the grammage of paper, the side length of the honeycomb hexagonal structure, and the like on the packaging of an item will be further discussed by means of experiments below. First, a plurality of foldable inner packaging structural members are prepared to perform a quasi-static compression test. In the present embodiment, the foldable inner packaging structural member employs a honeycomb structure. With regard to the quasi-static compression test, a box compression tester GK-KY25 (commercially available from Suzhou Sushi Testing Group Co., Ltd.) was used in the present test, the compression speed was 1 mm / min, and the basis for the ending determination of the compression depth was completely pressing an item into the interior of the honeycomb structure (at this point, a corresponding stress rose sharply). With regard to the item, it is a regular cylinder having a height of about 60 mm and a diameter of about 60 mm. The basic information of each sample is shown in Table 1 below: Table 1 Sample Size Unit Arrangement Unit Side Length (mm) Maximum Hole Diameter (mm) Minimum Hole Diameter (mm) Hole Spacing (mm) Hole Shape Grammage of Paper (g / m2) Sample A 135x105x100 6x7 10 4.5 2 7 circular 120 Sample B 135x105x100 6x7 10 5 2 7 oval 120 Sample C 135x105x100 6x7 10 4.5 2.5 14 circular 120 Sample D 135x105x100 6x7 10 4.5 2 7 circular 110 Sample E 135x105x100 6x7 10 4.5 2 7 circular 170 First, parameter information is explained as follows. With regard to the sample size, same represents the length, width, and height of the foldable inner packaging structural member. With regard to the unit arrangement, same represents the number of longitudinally arranged units and the number of horizontally arranged units. With regard to the unit side length, same represents the side length of the hexagon of the honeycomb structure. With regard to the maximum hole diameter and the minimum hole diameter, same represent a maximum longitudinal size and a minimum longitudinal size of a hole, for example, when the hole is a circular hole, the maximum hole diameter represents the maximum diameter of the hole, and the minimum hole diameter represents the minimum diameter of the hole. When the hole is an oval hole, the maximum hole diameter represents the maximum diameter of the hole on the long axis, and the minimum hole diameter represents the minimum diameter of the hole on the long axis. With regard to the hole spacing, same represents the spacing between adjacent edges of adjacent holes in the vertical direction. With regard to the grammage of paper, it represents the grammage of paper constituting the honeycomb structure. Moreover, it should be noted that a comparison between the above samples should be understood as a comparison between different embodiments of the present application, and not as a comparison with the prior art, and the experimental comparisons below should also be understood as such. 1. The effect of the unit side edge is discussed first. The unit side length of the honeycomb structure mainly affects the degree of tightness of an item being wrapped. The smaller the unit side length, the better the effect of the item being wrapped. FIG. 6 shows a top view of the honeycomb structure, in which shaded portions are honeycomb units located below a tested item. It can be seen that in the ideal case, a top-down area of the tested item is set to S, the number of honeycomb units completely located directly below the tested item is m, and the number of honeycomb units covered by the edges of the tested item is n. When the item is pressed into the honeycomb structure, as previously described, the walls of the honeycomb units located below the edges of the item are tom. Therefore, the number of honeycomb units that are crushed and tom is (m+n), the area of these honeycomb units may be expressed as SI, i.e., SI = (m+n)xS honeycomb units, a = S / SSl may be defined to represent the degree of tightness of the item being wrapped, and furthermore, the unit side length of the honeycomb unit is defined as 1, and according to a simple geometric relationship, the following can be obtained: S         S                 2S SI (m + , . v3( hi 4- v ■ honeycomb units ' Obviously, the smaller 1 is, the larger a is, and the higher the degree of tightness of the item being wrapped is, that is, the better the effect of being wrapped is. However, 1 should not be too small. 1 being too small results in difficulties in the production of the honeycomb structure, specifically, for example, if 1 is less than 4 mm, during the production process, the tensile force will be higher than an interlayer bonding force to which the paper can be subjected, causing paper fracture. Therefore, upon theoretical derivation and testing, it is appropriate to set the unit side length in the range of 5-12 mm. Preferably, the unit side length may be set to 10 mm. A length of 10 mm (there is a range or not) is adopted in all of the above samples as the unit side length. Moreover, it is to be understood that the present disclosure is not limited to the side length of 10 mm, and other appropriate unit side lengths may be employed according to actual circumstances, provided that they do not contradict the above theory in the present disclosure. 2. The effect of the size and spacing of the holes and the grammage of paper on crushing and tearing behaviors will be further discussed below. The size and spacing of the holes, and the grammage of paper can all have an impact on the ease of crushing of the honeycomb structure, therefore, the three collectively determine the ease of crushing of the honeycomb structure. As mentioned previously, in the present disclosure, the packaging of an item is implemented by the slice-by-layer crushing or progressive crushing of the honeycomb units below the item and the tearing of the walls (or between a honeycomb unit below the edge of the item and an adjacent honeycomb unit) below the edge of the item. The larger the size of the hole, the lower the strength of the honeycomb unit, and the easier the occurrence of tearing behavior. The smaller the size of the hole, the higher the strength of the honeycomb unit, and the more difficult the occurrence of the tearing behavior. The greater the hole spacing, the higher the strength of the honeycomb unit, and the more difficult the occurrence of the tearing behavior. The smaller the hole spacing, the lower the strength of the honeycomb unit, and the easier the occurrence of the tearing behavior. The lower the grammage of paper, the lower the strength of the honeycomb unit, and the easier the occurrence of both the tearing behavior and crushing behavior. The higher the grammage of paper, the greater the strength of the honeycomb unit, and the more difficult the occurrence of both the tearing behavior and the crushing behavior. Therefore, in order to ensure the production of the tearing behavior and the crushing behavior, the size of the hole should not be too small, the hole spacing should not be too large, and the grammage of paper should also not be too high, otherwise, it is difficult to generate crushing, and more importantly, since the honeycomb unit when being crushed is too difficult to tear, the honeycomb structure may have been crushed as a whole (i.e., a layer-by-layer crushing effect cannot be produced) when the paper has not been tom, and a situation occurs in which the honeycomb units outside the item are also deformed, that is, horizontal spreading of the crushing behavior replaces the tearing behavior. But at the same time, the size of the hole should not be too large, the hole spacing should not be too small, and the grammage of paper should not be too low, in order to ensure the most basic support function. First, test results of Sample A and Sample C in Table 1 are compared. For Sample A and Sample C, except for the minimum hole diameter and the hole spacing, all other conditions were the same. Specifically, the hole spacing in Sample A was set to 7 mm, while the hole spacing in Sample C was set to a larger size of 14 mm. The test results show that in Sample A, an item could be smoothly pressed into the honeycomb structure, while in Sample C, it was difficult to press the item into the honeycomb structure. Therefore, it can be seen that the hole spacing being too large will result in difficulty in produce tearing behavior. Test results of Sample A and Sample B are further compared. For Sample A and Sample B, except for the hole shape and the maximum hole diameter, all other conditions were the same. Specifically, the hole shape in Sample A was circular, and the maximum hole diameter was 4.5 mm, while the hole shape in Sample B was oval, and the maximum hole diameter was 5 mm. Upon testing, it was found that both Sample A and Sample B could produce good crushing and tearing behaviors. Next, Sample D and Sample E are further compared. For Sample D and Sample E, except for the grammage of paper, all other conditions were the same. Specifically, the grammage of paper in Sample D was 110 g / m2, while the grammage of paper in Sample E was 170 g / m2. Upon testing, it was found that when other conditions were appropriate, both paper having a grammage of 110 g / m2 and paper having a grammage of 170 g / m2 could also produce good crushing and tearing behaviors. As shown above, only five representative samples are listed for data comparison. After a series of theoretical deductions and experimental comparisons, the applicant has found the following parameter settings. The grammage range of paper may be set to be between 110-170 g / m2. Furthermore, the grammage range of paper may be set to be between 110-140 g / m2. The unit side length of the honeycomb unit may be set to be between 5-12 mm, optionally between 6-15 mm, optionally between 7-14 mm, and optionally between 8-12 mm. When the unit side length of the honeycomb unit is 5 mm, the gradient diameter range of the holes (that is, the maximum and minimum hole diameters decreasing in a gradient in the height direction) can be set to 1-2.5 mm. When the side length of the honeycomb unit is 12 mm, the gradient diameter range of the holes may be set to 2-5 mm. The spacing between edges of adjacent holes may be set to 10-200% of the maximum hole diameter. Next, the influence of the uniformity of holes, the relationship between the maximum hole diameter and the unit side length, and the number of holed walls on the packaging of the item will be further discussed by means of experiments. Similar to the previous test, a plurality of foldable inner packaging structural members were first prepared to perform a quasi-static compression test. In the present embodiment, the foldable inner packaging structural member is of a honeycomb structure. A box compression tester GK-KY25 (commercially available from Suzhou Sushi Testing Group Co., Ltd.) was employed in the test, the compression speed was 1 mm / min, and the basis for the ending determination of the compression depth was completely pressing the item into the interior of the honeycomb structure (at this point, a corresponding stress rose sharply). With regard to the item, it was a regular cylinder having a height of about 60 mm and a diameter of about 60 mm. The basic information of each sample is shown in Table 2 below: Table 2 Sample Size Unit Arrangement Unit Side Length (mm) Maximum Hole Diameter (mm) Minimum Hole Diameter (mm) Number of Holed Walls Grammage of Paper (g / m2) Sample F 135x105x100 6x7 10 4.5 4.5 6 110 Sample G 135x105x100 6x7 10 4.5 2 6 110 Sample H 135x105x100 6x7 10 4.5 2 6 170 Sample I 135x105x100 6x7 10 3 0.5 6 170 Sample J 135x105x100 6x7 10 4.5 2 6 170 Sample K 135x105x100 6x7 10 4.5 2 2 170 The meanings of the same parameters shown in Table 2 and Table 1 are the same and are not described herein again. In addition, for the relationship between the maximum hole diameter and the minimum hole diameter, using Sample F as an example, when the maximum hole diameter and the minimum hole diameter are the same, it indicates that the sizes of the holes on the wall are the same, that is, equal-size holes are provided. The number of holed walls is the number of walls provided with holes among the six walls of the honeycomb unit. Sample F and Sample G are compared first. For Sample F and Sample G, equal-size holes were provided in Sample F, and holes arranged in a gradient were provided in Sample G. In particular, the sizes of the holes in the height direction of the wall gradually decreased in a downward direction from the upper end portion. By comparison, it was found that in sample F, when the sample was pressed in, the honeycomb units located at the bottom also produced a crushing phenomenon. In contrast, by arranging the holes in a gradient in Sample G, the honeycomb units at the bottom did not produce a crushing phenomenon. In combination with the above analysis, it can be seen that by means of the holes arranged in a gradient, a layer-by-layer crushing effect in the height direction can be produced more effectively, thereby avoiding the occurrence of a crushing phenomenon at the bottom when an item is pressed into the honeycomb structure, thereby affecting the overall effect. Next, Sample H and Sample I are compared. For Sample H and Sample I, except for the maximum hole diameter and the minimum hole diameter (or the hole diameter gradient range), all other conditions were the same. Specifically, the hole diameter gradient range in Sample H was 4.5-2 mm, while the hole diameter gradient range in Sample I was 3-0.5 mm. By comparison, it was found that although both Sample H and Sample I could produce crushing and tearing behaviors, a certain collapsing phenomenon of the honeycomb units was also produced around the item in sample H, that is, the crushing behavior had a small range of spreading in the horizontal direction, which resulted in a poor wrapping effect after the item was pressed into Sample H. However, there was no crushing spreading in the horizontal direction in Sample I, which resulted in a better wrapping effect after the item was pressed into Sample I. Finally, Sample J and Sample K are compared. For Sample J and Sample K, except for the number of holed walls, all other conditions were the same. Specifically, holes were formed on six walls in Sample J, and holes were formed on only two walls in Sample K. Through comparison, it was found that although both Sample J and Sample K could produce crushing and tearing behaviors, a collapsing phenomenon of the honeycomb units around the item in Sample J was produced, and the tearing behavior of the walls without holes was also poor. This indicates that the crushing behavior of Sample J spread in the horizontal direction, which resulted in a poor wrapping effect after an item was pressed into Sample J. However, there was no crushing spread in the horizontal direction in Sample K, and since holes were provided on the six walls, the tearing behavior was also good, which resulted in a better wrapping effect of the item after being pressed into Sample K. As can be seen by the experimental comparison in Table 2, the crushing behavior of the holes arranged in a gradient is superior to the crushing behavior of the evenly distributed holes, and the holes arranged in a gradient can produce good layer-by-layer crushing behavior, which is consistent with the foregoing analysis. In addition, the applicant has found by means of the test that when the maximum hole diameter is less than 30% of the unit side length of the honeycomb unit, crushing spreading in the horizontal direction easily occurs, such that the honeycomb units around the item are easily deformed, resulting in poor wrapping. When the maximum hole diameter is greater than 40% of the unit side length of the honeycomb unit, the crushing spreading in the horizontal direction can be reduced well. In addition, the greater the number of the holed walls, the easier the crushing and tearing behaviors can occur, and the crushing spreading in the horizontal direction can be prevented more easily. Therefore, in the present disclosure, the maximum hole diameter is set to be greater than 40% of the unit side length of the honeycomb unit. Furthermore, the holes are preferably provided on the six walls. In addition, in the present embodiment, since the honeycomb unit is formed from a paperbased tearable material, the overall structure is 100% green and recyclable. Moreover, since the paper-based tearable material does not have elasticity, a permanent structure for protecting items can be formed, so that corresponding protection can be better provided for the items. A description of a foldable inner packaging structural member in a foldable packaging box according to another exemplary embodiment of the present disclosure will be given next. The basic configuration and operation of the foldable inner packaging structural member in this other embodiment are the same as the basic configuration and operation of the foldable inner packaging structural member in the aforementioned embodiment. Therefore, in the foldable inner packaging structural member in this other exemplary embodiment, a description of components having the same function and configuration as the components of the foldable inner packaging structural member in the aforementioned exemplary embodiment will be omitted. FIG. 18 shows another exemplary embodiment of the foldable inner packaging structural member 9 in the foldable packaging box according to the present disclosure. As shown in FIG. 18, the main difference between this other exemplary embodiment and the aforementioned exemplary embodiment is that a bottom support member 7 is provided at the bottom of the foldable inner packaging structural member 9. The bottom support member 7 is of a flat board shape and is detachably attached to the bottom of the foldable inner packaging structural member 9, for example, by means of adhesion, etc. When in use, the foldable inner packaging structural member 9 is placed on the ground by means of the bottom support member 7, thereby increasing the contact area with the ground such that a support effect is better achieved. When the foldable inner packaging structural member is required to be, for example, folded and transported, the bottom support member 7 may be separated from the foldable inner packaging structural member 9, and attached to the bottom of the foldable inner packaging structural member 9 when in use. As can be seen from the above, the foldable inner packaging structural member provided according to one or more embodiments of the present disclosure is of a honeycomb structure that is formed by tessellation of a plurality of hollow honeycomb units, and an upper end portion and a lower end portion of each of the honeycomb units are open and each include six walls, wherein the six walls are formed from paper and are provided with a plurality of holes having sizes that gradually decrease in the height direction from the upper end portion of the tessellation unit downward. The honeycomb structure guarantees that it can have a certain supporting effect and can produce crushing behavior when being pressed. The walls are formed from paper, which ensures that the walls can produce tearing behavior when being subjected to a tensile force. The setting of the holes ensures that the walls are more easily tom at the holes. Moreover, the holes arranged in a gradient guarantee the occurrence of layer-by-layer crushing and tearing behaviors, thereby reducing or avoiding crushing spreading in the horizontal direction. According to an alternative embodiment of the present disclosure, as shown in FIG. 19A, the present disclosure provides another foldable inner packaging structural member 9 which, compared to the embodiment shown in FIG. 16, is placed in another direction (i.e., perpendicular to the placement direction in FIG. 16), wherein at least one other wall 23 among the plurality of walls 23 of the plurality of hollow tessellation units 2 is provided with a transverse weakened portion 80. For example, the wall provided with the transverse weakened portion 80 may be a wall forming a hollow tessellation unit 2 located on a peripheral side among the plurality of hollow tessellation units 2. According to some embodiments, the transverse weakened portion 80 may be configured as at least one transverse tangent line 80 arranged in a direction perpendicular to the height direction. In the embodiment shown in FIG. 19A, the transverse tangent line 80 traverses all of the plurality of hollow tessellation units 2 of the packaging structural member 9 in the direction perpendicular to the height direction of the tessellation unit, i.e., at least one wall in each of the three layers of hollow tessellation units shown in the figure is tangent to the transverse tangent line. As shown in FIG. 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 FIG. 19A, when an item P is placed on the packaging structural member 2 and then pressure is applied, the item will press down on the tessellation units located therebelow, and the tessellation units located below the item will be crushed as a result of the pressure. In an embodiment not shown, the traverse tangent line 80 can also not traverse all of the tessellation units 2 in the direction perpendicular to the height direction of the tessellation units, e.g., only traverse 50% of the tessellation units, and the walls of the remaining 50% of the tessellation units do not have the traverse tangent line, that is, assuming that there are 10 layers of tessellation units in total, the traverse tangent line 80 cuts the walls of five layers of tessellation units 2 only in the direction perpendicular to the height direction of the tessellation units, and does not cut the walls of the remaining five layers of tessellation units 2. In this way, when an item is pressed into the packaging structural member along the traverse tangent line, the upper five layers of tessellation units are compressed, whereas the lower five layers of tessellation units are not compressed, thereby resulting in good buffering properties of packaging protection of the item. It should be noted that the configuration of the foldable inner packaging structural member 9 shown in FIG. 19A and FIG. 19B in the alternative embodiment may also be incorporated into the various exemplary embodiments shown in FIG. 1 to FIG. 18 unless a conflict is present in structure and / or function. For example, in a combination scheme, the tessellation unit 2 located in the middle of the inner packaging structural member 9 may employ the excision portion design described in the various exemplary embodiments shown in FIG. 1 to FIG. 18, whereas the tessellation units 2 located on the peripheral sides may employ the traverse tangent line design described in the alternative embodiment shown in FIGS. 19A and 19B. The sizes and values described herein are not to be understood as being strictly limited to the exact numerical values enumerated. Conversely, unless otherwise stated, each size is intended to mean an enumerated value and a functionally equivalent range around that value. For example, a size disclosed as “10 mm” is intended to mean “about 10 mm”. While some embodiments of the present disclosure have been shown and illustrated, those of ordinary skill in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the present disclosure, and the scope of the present disclosure is defined by the claims and their equivalents.
