Summary of the Invention

Problems to be Solved by the Invention

[0004] However, generally, the strength of the bottom of the product is high and the strength of the side surface is low, so the strength is not uniform. In the packaging cushioning body such as Patent Document 1, when an impact is applied to the side surface of a product with low strength, the impact is directly transmitted to the side surface, and there is a possibility that the side surface may be damaged or broken. In addition, although weight is applied to the bottom surface, in the packaging cushioning body of Patent Document 1, the packaging material may be crushed by its own weight, the product may tilt, and there is a risk of distortion or breakage of the product from the bottom surface.

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a packaging cushioning material that can appropriately protect the object to be packaged by arranging a packaging cushioning material having appropriate cushioning performance according to the strength of the object to be packaged.

[0011] (5) The packaging cushion material described in (4) above, wherein the plurality of types of packaging cushion material include a first structure packaging cushion material made of laminated corrugated cardboard, and the contact surface of the first structure packaging cushion material in contact with the packaged object is different, thereby providing two types of packaging cushion material with different cushioning performance.

[0012] (6) The type of packaging cushioning material with the lowest cushioning performance is the packaging cushioning material according to (5) above, wherein the surface of the packaging cushioning material of the first structure is perpendicular to the flow direction and stacking direction of the corrugated cardboard core with respect to the packaged object.

[0013] (7) The packaging cushioning material described in (1) above, wherein the packaging cushioning material is constructed by folding the paper material, and the lower the cushioning performance, the smaller the degree of hollowness, which is the volume of the paper material relative to the total volume of the packaging cushioning material. [Effects of the Invention]

[0014] The packaging cushioning material according to the present invention includes multiple types of packaging cushioning materials that have different cushioning performance due to differences in the way the paper material is assembled or differences in the contact surfaces.

Mode for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. However, the scope of the present invention is not limited to the disclosed embodiments. In the description of the drawings, the same reference numerals are given to the same elements, and duplicate descriptions are omitted. Also, the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may be different from the actual ratios.

[0017] Figure 1 is a perspective view showing a packaging package 100 to which the packaging cushioning material 30 according to this embodiment is applied. As shown in Figure 1, the packaging package 100 consists of a product 10, which is the article to be protected, an outer box 20, and a plurality of packaging cushioning materials 30. The packaging package 100 may also include a pallet 40 or a bottom board for packaging. The product 10 is, for example, an electronic device such as a home appliance or a printer. The product 10 is the packaged item that is protected and packaged by the packaging cushioning material 30. The outer box 20 is, for example, made of corrugated cardboard and has a roughly rectangular parallelepiped shape with an open bottom. In the state of the packaging package 100, a plurality of packaging cushioning materials 30 are placed between the outer surface of the product 10 and the inner surface of the outer box 20, and between the bottom surface of the product 10 and the pallet 40.

[0018] The packaging cushioning material 30 is made of paper material and includes multiple types of packaging cushioning material 30 with different cushioning performance due to differences in the way the paper material is assembled or the direction of contact. For example, as described later, there are six types of packaging cushioning material 301 to 306 (these may be collectively referred to as packaging cushioning material 30) depending on the level of cushioning performance. The pallet 40 is made of wooden boards or resin material and is constructed to withstand the weight of the product 10. The four corners of the pallet 40 are provided with members such as corner pieces for positioning the outer box 20 and the multiple packaging cushioning materials 30 (not shown). The four sides of the pallet 40 are provided with openings for inserting forklift forks. Note that Figure 1 shows the outer box 20 removed from the top.

[0019] (Packaging cushioning material 30 for structures 1 to 5) The first to fifth structures of the packaging cushioning material 30 will be described below with reference to Figures 2 to 7. All of these packaging cushioning materials 30 are made of paper material, but differ in how the paper material is assembled. For example, corrugated cardboard is used as the paper material. Furthermore, all of the packaging cushioning materials 30 from the first to the fifth structures are made of the same type of corrugated cardboard (corrugated cardboard sheet 3a described later). In other words, the packaging cushioning materials 30 from the first to the fifth structures achieve different cushioning performance by using corrugated cardboard with the same material thickness and composition for the liner and core, but with different assembly methods.

[0020] (1st structure) Figure 2 shows the structure of the first type of packaging cushioning material, where Figure 2(a) is a perspective view and Figure 2(b) is a cross-sectional view. The first type of packaging cushioning material shown in Figure 2 has anisotropy, with the Young's modulus varying depending on the direction of pressure (load). Therefore, by varying the contact surfaces, the first type of packaging cushioning material functions as two types of packaging cushioning material, the first type 301 and the second type 302, as described later. The first type of packaging cushioning material 301 or 302 (hereinafter simply referred to as 301, etc.) has a structure in which multiple corrugated cardboard sheets 3a are laminated. One corrugated cardboard sheet 3a has a three-layer structure in which a core 3b is sandwiched between liners 3c and 3d. The core 3b is a corrugated paper layer. The liners 3c and 3d are flat paper layers. In Figure 2, the X direction is the stacking direction, the Y direction is the wave flow direction of the core 3b, and the Z direction is perpendicular to the flow direction and stacking direction of the core. In Figure 2(a), the top surface in the Z direction corresponds to a surface perpendicular to the flow direction and stacking direction of the core.

[0021] The first structure of the packaging cushioning material 301 is assembled by stacking multiple corrugated cardboard sheets 3a in the X direction and bonding them together without gaps. The first structure of the packaging cushioning material 301 has no beams and has an extremely small degree of hollowness. Here, the degree of hollowness is the void ratio, which is the ratio of the volume of voids to the volume of the packaging cushioning material 30 in an unloaded state. When calculating the degree of hollowness, one corrugated cardboard sheet 3a may be calculated as having a filling rate of 100%. In such a case, as shown in the example in Figure 2, the degree of hollowness is zero.

[0022] (Second structure) Figure 3 shows the configuration of the second structure of the packaging cushioning material, where Figure 3(a) is a perspective view and Figure 3(b) is a cross-sectional view. The second structure of the packaging cushioning material shown in Figure 3 functions as a third type of packaging cushioning material 303. The second structure of the packaging cushioning material 303 has two horizontal beams (X direction) connecting walls that extend in the vertical direction (Z direction), and has a small degree of hollowness. The second structure of the packaging cushioning material 303 is assembled by folding a single corrugated cardboard sheet 3a into an accordion shape and surrounding it, and its cross-sectional shape corresponds to a rectangle with two horizontal beams added.

[0023] (Third structure) Figure 4 shows the configuration of the third structure of the packaging cushioning material, where Figure 4(a) is a perspective view and Figure 4(b) is a cross-sectional view. The third structure of the packaging cushioning material shown in Figure 4 functions as a fourth type of packaging cushioning material 304. The third structure of the packaging cushioning material 304 is assembled by folding a single corrugated cardboard sheet 3a in a spiral rotational manner. The third structure of the packaging cushioning material 304 is assembled by folding a single corrugated cardboard sheet 3a at a 90-degree angle six times, and the cross-sectional shape corresponds to adding a horizontal beam to a rectangular shape. The third structure of the packaging cushioning material 304 has one horizontal (X-direction) beam and a moderate degree of hollowness.

[0024] (4th structure) Figure 5 shows the configuration of the fourth structure of the packaging cushioning material, where Figure 5(a) is a perspective view and Figure 5(b) is a cross-sectional view. The fourth structure of the packaging cushioning material shown in Figure 5 functions as the fifth type of packaging cushioning material 305. The fourth structure of the packaging cushioning material 305 is assembled by rotating and folding a single corrugated cardboard sheet 3a. The fourth structure of the packaging cushioning material 305 is assembled by folding a single corrugated cardboard sheet 3a once at a 45-degree angle, followed by folding it three times at 90 degrees, resulting in a cross-sectional shape that corresponds to a rectangle with diagonal beams. The fourth structure of the packaging cushioning material 305 has one beam in the diagonal direction (XY direction) and has a large degree of hollowness.

[0025] (5th structure) Figure 6 shows the configuration of the fifth structure of the packaging cushioning material, where Figure 6(a) is a perspective view and Figure 6(b) is a cross-sectional view. The fifth structure of packaging cushioning material shown in Figure 6 functions as the sixth type of packaging cushioning material 306. The fifth structure of packaging cushioning material 306 is assembled by rotating and folding one roll of a single corrugated cardboard sheet 3a. The fifth structure of packaging cushioning material 305 is assembled by folding a single corrugated cardboard sheet 3a at a 90-degree angle three times, and has a rectangular cross-sectional shape. The fifth structure of packaging cushioning material 306 has no beams and has a maximum degree of hollowness.

[0026] Figure 7 shows a list of the configurations of the first to fifth structures of the packaging cushioning material 30 described above.

[0027] Next, referring to Figures 8 to 16, we will describe the first to sixth types of packaging cushioning materials 301 to 306, each with different cushioning performance, using the configurations of the first to fifth structures of the packaging cushioning material 30 described above.

[0028] (Type 1 to Type 6 packing cushioning materials 301 to 306) Figure 8 is a schematic diagram illustrating the first type of packaging cushioning material 301. Figure 8(a) is a perspective view, and Figure 8(b) is a diagram showing the positional relationship of the first type of packaging cushioning material 301 on the product 10. As shown in Figure 8(a), in the first type of packaging cushioning material 301, the first structure of packaging cushioning material 30 (see Figure 2) is used with the surface perpendicular (Z direction) to the wave flow direction (Y direction) and the lamination direction (X direction) as the contact surface.

[0029] Figure 9 is a schematic diagram illustrating the second type of packaging cushioning material 302. Figure 9(a) is a perspective view, and Figure 9(b) is a diagram showing the positional relationship of the packaging cushioning material 302 on the product 10. As shown in Figure 9(b), in the second type of packaging cushioning material 302, the first structure of packaging cushioning material 30 (see Figure 2) is used with the surface perpendicular to the lamination direction as the contact surface. The relationship between the packaging cushioning material 302 and the internal strength (stay structure, etc.) of the product 10's casing will be described later.

[0030] Figure 10 is a schematic diagram illustrating the third type of packaging cushioning material 303. Figure 10(a) is a perspective view, and Figure 10(b) is a diagram showing the positional relationship of the packaging cushioning material 303 to the product 10. As shown in Figure 10(b), in the third type of packaging cushioning material 303, the second structure of packaging cushioning material 30 (see Figure 3) is used with the surface perpendicular to the extension direction of the beam as the contact surface. In the third type of packaging cushioning material 303, the side surface of the second structure of packaging cushioning material 30, which has a horizontal beam, is used as the contact surface.

[0031] Figure 11 is a schematic diagram illustrating the fourth type of packaging cushioning material 304. Figure 11(a) is a perspective view, and Figure 11(b) is a diagram showing the positional relationship of the packaging cushioning material 304 to the product 10. As shown in Figure 11(b), in the fourth type of packaging cushioning material 304, the third structure of packaging cushioning material 30 (see Figure 4) is used with the surface perpendicular to the extension direction of the beam as the contact surface. In the fourth type of packaging cushioning material 304, the side surface of the third structure of packaging cushioning material 30, which has a horizontal beam, is used as the contact surface.

[0032] Figure 12 is a schematic diagram illustrating the fifth type of packaging cushioning material 305. Figure 12(a) is a perspective view, and Figure 12(b) is a diagram showing the positional relationship of the packaging cushioning material 305 to the product 10. As shown in Figure 12(b), in the fifth type of packaging cushioning material 305, the fourth structure of the packaging cushioning material 30 (see Figure 5) is used with the surface at approximately 45 degrees to the extending direction of the beam as the contact surface. In the fifth type of packaging cushioning material 305, the side surface of the fourth structure of the packaging cushioning material 30 is used as the contact surface.

[0033] Figure 13 is a schematic diagram illustrating the sixth type of packaging cushioning material 306. Figure 13(a) is a perspective view, and Figure 13(b) is a diagram showing the positional relationship of the packaging cushioning material 306 on the product 10. As shown in Figure 13(b), in the sixth type of packaging cushioning material 306, the side surface of the fifth structure packaging cushioning material 30 (see Figure 6) is used as the contact surface.

[0034] (Buffer performance) Figure 14 shows the Young's modulus test results for Type 1 and Type 2 packaging cushioning materials 301 and 302. Figure 15 shows the cushioning performance simulation results for Type 2 to Type 6 packaging cushioning materials 302 to 306. In these tests or simulations, corrugated cardboard sheets of the same type (same material thickness and composition for the liner and core) were used.

[0035] As shown in Figure 14, the Young's modulus of the first type of packaging cushioning material 301 is 11 MPa, and the Young's modulus of the second type of packaging cushioning material 302 is 1.17 MPa. Compared to the first type of packaging cushioning material 301, the Young's modulus of the second type of packaging cushioning material 302 is approximately 1 / 10, indicating that the deformation amount for the same load is approximately 10 times greater, thus demonstrating superior cushioning performance.

[0036] Figure 15 shows that, compared to Type 2 packaging cushioning material 302, the deformation of Type 3 packaging cushioning material 303 is 3.7 times, and the deformation of Type 4 packaging cushioning material 304 is 8.5 times. It also shows that the deformation of Type 5 packaging cushioning material 305 is 54.3 times, and the deformation of Type 6 packaging cushioning material 306 is 73.9 times. From these results, it can be seen that the cushioning performance, from highest to lowest, is as follows: Type 6 packaging cushioning material 306 > Type 5 packaging cushioning material 305 > Type 4 packaging cushioning material 304 > Type 3 packaging cushioning material 303 > Type 2 packaging cushioning material 302 > Type 1 packaging cushioning material 301.

[0037] (Applicability of packing cushioning materials 301-306 of types 1-6) Figure 16 is a table showing the relationship between the characteristics of Type 1 to Type 6 packaging cushioning materials 301 to 306 and the strength of the product 10 to which they are applied.

[0038] Type 1 packaging cushioning material 301 has a cushioning performance level of 1 (lowest). Type 1 packaging cushioning material 301 is applied to parts of the product 10 that are heavy products and support the entire weight of the product on a strong bottom plate surface. For example, as shown in Figure 8(b), when the entire weight of the product 10 is supported on the bottom plate surface, Type 1 packaging cushioning material 301 is placed between the bottom plate surface and the top surface of the pallet 40. For example, if the product 10 is a heavy product such as a printer, it is useful to place the cushioning material between the bottom plate surface and the pallet 40 in the packaging package 100 to reduce the load on the casters during warehouse storage or transportation, so that the casters are lifted off the ground.

[0039] Type 2 packaging cushioning material 302 has a cushioning performance level of 2. Type 2 packaging cushioning material 302 is applied to the top surface (upper surface) of a product that has strong stays or the like on the inside of the outer packaging. Alternatively, Type 2 packaging cushioning material 302 is applied to the side surface of a product that has strong stays or the like on the inside of the outer packaging. For example, as shown in Figure 9(b), Type 2 packaging cushioning material 302 is applied when product 10 has a strong stay s1 on the inside of the outer packaging.

[0040] The third type of packaging cushioning material 303 has a cushioning performance level of 3. The third type of packaging cushioning material 303 is applied to the exterior sides and top surfaces, which have relatively high strength. For example, as shown in Figure 10(b), the third type of packaging cushioning material 303 is applied when there is a relatively high-strength stay s2 on the inside of the exterior.

[0041] Type 4 packaging cushioning material 304 has a cushioning performance level of 4 (medium). Type 4 packaging cushioning material 304 is applied to the exterior sides and top surfaces with medium strength. For example, as shown in Figure 11(b), Type 4 packaging cushioning material 304 is applied when there is a stay s3 on the inside of the exterior that is not very strong.

[0042] Type 5 packaging cushioning material 305 has a cushioning performance level of 5. Type 5 packaging cushioning material 305 has a configuration that balances both product support and cushioning. Type 5 packaging cushioning material 305 is applied to the exterior sides and top surfaces with moderate strength, where the exterior is easily deformed, or where quality against impact marks and scratches is critical. For example, as shown in Figure 12(b), Type 5 packaging cushioning material 305 is applied when there is a stay s4 on the inside of the exterior that is not very strong. In addition, Type 5 packaging cushioning material 305 may be placed in the following locations on the product 10. (5-1) The side of the product has structures such as stays that support the exterior on the inside, but the strength is not high. (5-2) The top surface of the product has structures such as stays that support the exterior on the inside, but its strength is not high. (5-3) The exterior is somewhat resistant to deformation, but the inner support on the side of the product is weak. (5-4) The exterior is somewhat resistant to deformation, but the inner support on the top surface of the product is weak. (5-5) The top surface of the product exterior, which is weak against external forces and easily deformed.

[0043] Type 6 packaging cushioning material 306 has a cushioning performance level of 6 (the highest). Type 6 packaging cushioning material 306 cushions external impacts so that the product does not deform. Type 6 packaging cushioning material 306 is applied to the exterior sides and top surfaces, which have low strength and are prone to deformation, or to areas where quality against impact marks and scratches is critical. For example, as shown in Figure 13(b), Type 6 packaging cushioning material 306 is applied when there are no stays on the inside of the exterior (the stay S6 in the figure is shown as an example where it is positioned away from the contact point). In addition, Type 6 packaging cushioning material 306 may be placed in the following locations on the product. (6-1) The side of the product that does not have any structures such as stays that support the exterior on the inside. (6-2) The top surface of the product that does not have any structures such as stays that support the exterior on the inside. (6-3) The outer surface of the product is vulnerable to external forces and easily deformed. (6-4) The top surface of the product exterior, which is weak against external forces and easily deformed.

[0044] Figures 17 and 18 illustrate examples of the application of the various packaging cushioning materials described above. Figure 17 is a perspective view from the front, and Figure 18 is a perspective view from the back. The selection of various packaging cushioning materials is carried out according to the following procedure. (a) Place the first type of packaging cushioning material 301 between the bottom surface of product 10 and the pallet 40. (b) Next, if there are stays inside the outer packaging, the packing cushioning materials 302 to 305 of types 2 to 5 shall be placed depending on the strength of the stays. Furthermore, if the outer packaging is easily deformed or if there are areas where quality is critical against dents, a packing cushioning material 30 with higher cushioning performance shall be applied. (c) Finally, if there are no stays inside the exterior, or if the exterior is easily deformed, place the sixth type of packing cushioning material 306.

[0045] As described above, in this embodiment, the packaging cushioning material is positioned so that the stronger the object being packaged, the lower the cushioning performance at the contact point between the packaging cushioning material and the object being packaged. Here, areas of high strength in the object being packaged include areas where there is a structure supporting the outer casing internally, and / or areas where the outer casing itself is strong. By having such a configuration, packaging cushioning material with appropriate cushioning performance can be applied according to the strength of the object being packaged, thereby enabling proper protection of the object being packaged.

[0046] Furthermore, in this embodiment, the cushioning performance differs depending on how the paper material is assembled, as at least one of the following can be changed: the presence or absence of beams, the number of beams, and the orientation of the beams. In this way, even if only one type of paper material is used, multiple types of packaging cushioning materials with different cushioning performance can be constructed.

[0047] Furthermore, in this embodiment, a first-structure packaging cushioning material made of laminated paper material is included, and by having different contact surfaces of the first-structure packaging cushioning material in contact with the packaged object, it is used as two types of packaging cushioning materials with different cushioning performance. In this way, even if the same-structure packaging cushioning material is used from a single type of paper material, two types of packaging cushioning materials with different cushioning performance can be constructed.

[0048] The configuration of the packaging cushioning material 30 described above is merely an explanation of the main components for illustrating the features of the above embodiment, and is not limited to the above configuration. Various modifications can be made within the scope of the claims. Furthermore, it does not preclude the configurations found in general packaging packages.

[0049] For example, in the above embodiment, an example was shown in which first to sixth types of packaging cushioning materials 30, each with different cushioning performance, are applied. However, the number of types is not limited to this; there may be two or three types, or even seven or more types. For example, three types of packaging cushioning materials, namely the first, second, and fifth types, may be applied.

[0050] While embodiments of the present invention have been described and illustrated in detail, the disclosed embodiments are for illustrative purposes only and are not limiting. The scope of the present invention should be interpreted in accordance with the language of the appended claims. [Explanation of Symbols]
