Description

[Technical field]

[0001] The present invention relates to a packaging member having a pallet with a tray and an upper box, and in particular to a packaging member that includes a ramp for moving the packaged items from the product placement surface of the pallet with a tray. [Background technology]

[0002] Conventionally, when a heavy product (packaged item) such as electronic equipment is packed in a pallet with a tray and an upper case (packaging material) for transport and storage, the product placement surface of the pallet with tray has a step with respect to the floor. Therefore, a method is generally used in which a slope is formed at the step, and the product is moved up the slope as is in the case of a product with casters, or on a dolly with casters in the case of a product without casters or when the casters are still packed.

[0003] Here, if the slope is a plate-like member, there is a risk that the slope will bend, buckle, or break if the product is heavy.

[0004] Therefore, Patent Document 1 discloses a packing case having a slope that is pivotally supported on a buffer plate and folded and stored inside an upper case, and a reinforcing member that is attached to the slope to support and reinforce the slope on the floor surface.

[0005] [Patent Document 1] JP 2006-96356 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the configuration of Patent Document 1, a reinforcing member is provided on the slope to prevent the slope from bending, buckling, or breaking. However, when a reinforcing member is provided on the slope, the volume occupied by the slope in the packaging case increases, which causes a problem that the overall volume of the packaging case increases, leading to an increase in the size of the packaging case. In addition, even though the slope is a member that is used only once to unload the product, the amount of material used for the slope itself increases, which causes a problem that leads to an increase in the cost of the packaging member.

[0007] In view of the above problems, the present invention aims to provide a packaging material that can include a ramp for moving the packaged items, and that can prevent the packaging material from becoming larger and the amount of material used from increasing. [Means for solving the problem]

[0008] In order to achieve the above object, a first configuration of the present invention is a packaging member including a pallet with a tray, an upper case, a cushioning member, and a slope plate. The pallet with tray has a tray on which the packaged item is placed, and a pallet fixed to the lower surface of the tray. The upper case is cylindrical with an open bottom, and covers the side and upper surfaces of the packaged item. The cushioning member is placed between the packaged item and the upper case. The slope plate is connected to the pallet with tray when the packaged item placed on the tray is moved. The cushioning member is placed as a reinforcing stand below the slope plate connected to the pallet with tray. Effect of the Invention

[0009] According to the first configuration of the present invention, by using the buffer material as a reinforcing base for the slope plate, it is not necessary to pack the reinforcing base as a separate member, and the volume of the packaging material can be reduced. Therefore, transportation and storage can be achieved with a minimum packaging volume, which reduces transportation and storage costs. In addition, the amount of material used for the packaging material itself can be reduced, which contributes to reducing the cost of the packaging material. Furthermore, the number of members required for the slope, which is used only when opening the packaging material, can be reduced. As a result, this leads to a reduction in the amount of used packaging material discarded and collected, making it environmentally friendly. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing a state in which a product P is placed in a packaging member 1 according to a first embodiment of the present invention. As shown in Fig. 1, the packaging member 1 is composed of a pallet 2 with a tray, an upper case 3, and a cushioning member 4.

[0012] The tray-equipped pallet 2 is composed of a tray 5 and a pallet 6 fixed to the underside of the tray 5. The tray 5 has a rectangular bottom surface 5a (see FIG. 2) on which the product P is placed, and four flaps 5b connected to the four sides of the bottom surface 5a. Through holes 8a are formed at predetermined locations of the flaps 5b.

[0013] Pallet 6 is made up of a number of support columns 6a formed, for example, by bending cardboard, and a top plate 6b and a bottom plate 6c fixed to the top and bottom surfaces of each support column 6a, with arm insertion holes 9 formed between each support column 6a for inserting the arm of a forklift or hand pallet (cart for transporting pallets). Top plate 6b is fixed to bottom surface 5a of tray 5 with nails, screws, etc. (not shown). Pallet 6 may be made of wood.

[0014] The tray-equipped pallet 2 also serves as the bottom surface of the packaging member 1, and since there is no need to place the packaging member 1 on the pallet after the product P is packed, this makes it easy to pack and transport large products in particular.

[0015] The upper case 3 is a rectangular parallelepiped with an open bottom, and covers the side and top of the product (packaged item) P. A through hole 8b is formed in the lower end of the upper case 3 at a position overlapping with the through hole 8a of the flap 5b. The tray-equipped pallet 2 and the upper case 3 are integrally connected by inserting a fastener (not shown) into the through holes 8a and 8b with the holes overlapping. Note that, although the upper case 3 used in this embodiment has cylindrical side and top portions integrally formed therewith, an upper case 3 that can be separated into side portions and a box-shaped top portion may also be used.

[0016] The cushioning material 4 is disposed in the gap between the product P and the upper case 3, and protects the product P from external impacts. The cushioning material 4 is formed by folding a cardboard sheet into a predetermined shape. The cushioning material 4 includes a side cushioning material 41 disposed on the side surface of the product P, and an upper cushioning material 42 disposed on the upper surface of the product P.

[0017] The side cushioning materials 41 are arranged in the vertical direction so as to cover the four corners of the side of the product P. A predetermined gap is formed between the side cushioning materials 41 and the flap 5b, into which the lower end of the upper case 3 is inserted. Two top cushioning materials 42 are arranged in parallel on the top surface of the product P. The detailed configuration of the top cushioning materials 42 will be described later.

[0018] 2 is a perspective view of a tray 5 constituting the tray-equipped pallet 2 of the packaging member 1 of the first embodiment. As shown in FIG. 2, a pair of support plates 51 and a pair of slope plates 52 are superimposed on a bottom surface 5a of the tray 5.

[0019] The support plates 51 are fixed to the bottom surface 5a along two opposing sides of the bottom surface 5a (the two left and right sides in FIG. 2). The support plates 51 face casters 60 (see FIG. 9) provided at the four corners of the product P. The slope plates 52 are arranged in parallel between the pair of support plates 51. The slope plates 52 are detachable from the bottom surface 5a.

[0020] Fig. 3 is a perspective view showing a state in which the slope plate 52 has been removed from the tray 5 of Fig. 2. Fig. 4 is a perspective view of the slope plate 52 as seen from the back side. As shown in Fig. 3, two engagement holes 53 are formed in the portion of the bottom surface 5a where the slope plate 52 overlaps. As shown in Fig. 4, positioning protrusions 52a are formed on the back side of the slope plate 52.

[0021] When the slope plate 52 is placed on the bottom surface 5a of the tray 5, the positioning protrusions 52a formed on the back side of the slope plate 52 fit into the engagement holes 53 on the bottom surface 5a. This allows the slope plate 52 to be accurately attached to a predetermined position on the bottom surface 5a. It also prevents the slope plate 52 from shifting or falling off due to vibrations or shocks during transportation.

[0022] 5 is a perspective view of the upper cushioning material 42 placed on the upper surface of the product P, seen from the side of the contact surface with the product P. The upper cushioning material 42 is formed by folding a sheet material such as a cardboard sheet. The upper cushioning material 42 has a buffer plate 421, a first support portion 422, a second support portion 423, and a third support portion 424.

[0023] The buffer plate 421 is rectangular and divided into a first region 421a, a second region 421b, and a third region 421c by folding lines L1 and L2. An insertion piece 425 is formed in the first region 421a. Insertion holes 426a and 426b are formed in the second region 421b and the third region 421c, respectively.

[0024] The first support column 422 is formed by folding a sheet material connected to the edge of the buffer plate 421 on the first region 421a side into a rectangular tube shape, or by folding and adhering another sheet material. An inclined surface 422a that slopes downward toward the second support column 423 is formed at the tip of the first support column 422 (the upper surface in FIG. 5). An opening 422b is formed in the inclined surface 422a. The inside of the first support column 422 is filled with a reinforcing member 427 formed by stacking cardboard sheets in the horizontal direction.

[0025] The reinforcing member 427 is laminated so that the grain direction of the cardboard sheets (extension direction of the thin tubes formed by the flat and corrugated sheets) is vertical. This makes it difficult for the reinforcing member 427 to buckle when the upper surface cushioning material 42 is used as a reinforcing base for the slope plate 52, as described below, and increases the strength of the first support portion 422. In addition, when the upper surface cushioning material 42 is placed on the upper surface of the product P, the shock absorbing properties (cushioning properties) of the first support portion 422 against impacts from the side can be increased.

[0026] The second support column 423 is formed by folding a sheet material connected to the edge of the buffer plate 421 on the third region 421c side into a rectangular tube shape, or by folding and adhering another sheet material. The height of the second support column 423 is lower than that of the first support column 422. An inclined surface 423a is formed at the tip of the second support column 423 (upper surface in FIG. 5) that is inclined in the same direction as the inclined surface 422a of the first support column 422. The inclination angle of the inclined surfaces 422a, 423a is approximately the same as the inclination angle of the slope plate 52 when the slope plate 52 is used.

[0027] The third support column 424 is formed by folding a sheet material connected to the edge of the first region 421a of the buffer plate 421 perpendicular to the first support column 422 into a rectangular tube shape, or by folding and adhering another sheet material. The third support column 424 is disposed along substantially the entire edge of the buffer plate 421 from the first support column 422 to the second support column 423 so as to be perpendicular to the first support column 422 and the second support column 423. The height of the third support column 424 is lower than the first support column 422 and higher than the second support column 423.

[0028] In the packaging member 1 of this embodiment, when the product P is moved from the tray-equipped pallet 2 using the slope plate 52, the upper surface cushioning material 42 can be used as a reinforcing base for the slope plate 52. Here, in the upper surface cushioning material 42 having the shape (first shape) shown in Fig. 5, the distance between the first support column portion 422 and the second support column portion 423 is set according to the shape of the upper surface of the product P. Therefore, when using the upper surface cushioning material 42 as a reinforcing base, it is necessary to adjust the distance between the first support column portion 422 and the second support column portion 423.

[0029] 6 and 7 are diagrams showing a folding procedure when the upper cushioning material 42 is used as a reinforcing base for the slope plate 52. When the upper cushioning material 42 is used as a reinforcing base, as shown in Fig. 6, the buffer plate 421 is valley-folded along the folding line L1, and further mountain-folded along the folding line L2. As a result, the first region 421a, the second region 421b, and the third region 421c of the buffer plate 421 are folded into a Z-shape in side view.

[0030] 7, the second region 421b and the third region 421c are overlapped on the first region 421a. At this time, the insertion hole 426a of the second region 421b and the insertion hole 426b of the third region 421c overlap with each other. Then, the insertion piece 425 of the first region 421a is inserted into the insertion holes 426a and 426b, so that the buffer plate 421 is held in a folded state. In the upper surface buffer material 42 of the shape (second shape) of FIG. 7, the distance between the first support portion 422 and the second support portion 423 is set so that the inclined surface 422a of the first support portion 422 and the inclined surface 423a of the second support portion 423 are in surface contact with the back surface of the slope plate 52 when used as a reinforcing base for the slope plate 52.

[0031] That is, by folding the buffer plate 421 along fold lines L1, L2 (first fold lines) perpendicular to the extension direction of the slope plate 52, or by extending the folded state, it is possible to change the shape to either the shape (first shape) of FIG. 5 in which the spacing between the first support portion 422 and the second support portion 423 is set to match the shape of the product P, or the shape (second shape) of FIG. 7 in which the spacing between the first support portion 422 and the second support portion 423 is set to match use as a reinforcing base for the slope plate 52.

[0032] Fig. 8 is a perspective view showing a state in which, in the packaging member 1 of the first embodiment, the slope plate 52 is removed from the tray 5 of the tray-equipped pallet 2 and connected to the flap 5b, and an upper surface cushioning material 42 is placed below the slope plate 52 as a reinforcing base. Fig. 9 is a perspective view showing a state in which the product P is moved from the tray-equipped pallet 2 using the slope plate 52. The procedure for opening the packaging member 1 and taking out the product P will be described with reference to Figs. 8 and 9.

[0033] When opening the packaging member 1, the fasteners (not shown) inserted into the through holes 8a and 8b are removed, and then the upper case 3 (see FIG. 1) is removed. Then, the side cushioning material 41 and the upper cushioning material 42 are removed, and the flap 5b is tilted outward.

[0034] Next, the slope plate 52 is removed from the bottom surface 5a of the tray 5. The casters 60 of the product P are placed on the support plate 51, and the weight of the product P is not applied to the slope plate 52. In addition, the casters 60 form a gap between the slope plate 52 and the product P. Therefore, the slope plate 52 can be easily removed by lifting the slope plate 52 to release the engagement between the positioning protrusions 52a (see FIG. 4) and the engagement holes 53 on the bottom surface 5a, and then pulling it out horizontally.

[0035] Next, the removed slope plate 52 is connected to the tray-equipped pallet 2, and the upper surface cushioning material 42 is placed below the slope plate 52 as a reinforcing base. Specifically, the positioning protrusion 52a of the slope plate 52 is fitted into the through hole 8a of the flap 5b. This positions the slope plate 52 relative to the tray-equipped pallet 2.

[0036] Next, the upper surface cushioning material 42 folded as shown in Fig. 7 is placed under the slope plate 52 with the buffer plate 421 facing downward. The upper surface cushioning material 42 is positioned so that the first support portion 422 is close to the tray-equipped pallet 2 and the second support portion 423 is away from the tray-equipped pallet 2. At this time, the positioning protrusion 52a of the slope plate 52 is fitted into the opening 422b formed in the first support portion 422 of the upper surface cushioning material 42 via the through hole 8a.

[0037] This positions the slope plate 52 and the upper surface cushioning material 42, and the inclined surfaces 422a, 423a of the first and second support pillars 422, 423 come into surface contact with the underside of the slope plate 52. In addition, the third support pillar 424 is disposed along the outer edge of the slope plate 52. A portion of the third support pillar 424 protrudes upward beyond the slope plate 52. In this manner, a slope from the tray-equipped pallet 2 to the floor surface as shown in Figure 8 is completed.

[0038] Then, as shown in FIG. 9, the casters 60 of the product P are moved from the support plate 51 to the slope plate 52, and the product P is moved along the slope plate 52 from the tray-equipped pallet 2 to the floor surface.

[0039] In this embodiment, the upper cushioning material 42 is used as a reinforcing base for the slope plate 52. This eliminates the need to include the reinforcing base as a separate component, and allows the volume of the packaging material 1 to be reduced. This allows transportation and storage with a minimum packaging volume, thereby reducing transportation and storage costs. In addition, the amount of material used for the packaging material 1 itself can be reduced, which contributes to lowering the cost of the packaging material 1. Furthermore, the number of components required for the slope, which is used only when opening the packaging material 1, can be reduced. As a result, this also leads to a reduction in the amount of used packaging material 1 that is discarded and collected, making it environmentally friendly.

[0040] Furthermore, the upper surface cushioning material 42 can change the distance between the first support column portion 422 and the second support column portion 423 by bending the buffer plate 421. This makes it possible to appropriately adjust the distance between the first support column portion 422 and the second support column portion 423 depending on whether the upper surface cushioning material 42 is used as a buffer material or as a reinforcing base for the slope plate 52.

[0041] Furthermore, when the upper surface cushioning material 42 is disposed below the slope plate 52, the third support pillar 424 is disposed along the outer edge of the slope plate 52, and a part of the third support pillar 424 protrudes above the slope plate 52. As a result, the third support pillar 424 functions as a guide to prevent the caster 60 from falling off the slope plate 52.

[0042] In addition, since the slope plate 52 is packed in a state where it is overlapped on the bottom surface 5a of the tray 5, no packing space is required for the slope plate 52. In addition, by engaging the positioning protrusions 52a of the slope plate 52 with the engaging holes 53 of the bottom surface 5a, it is possible to prevent the slope plate 52 from shifting or falling off.

[0043] Furthermore, by fitting the positioning protrusion 52a of the slope plate 52 into the through hole 8a for attaching a fastener formed in the flap 5b of the tray 5 and the opening 422b formed in the first support portion 422 of the upper cushioning material 42, the slope plate 52 can be easily aligned with the tray 5 and the upper cushioning material 42.

[0044] Furthermore, when the slope plate 52 is placed on the bottom surface 5a of the tray 5, the upper surface of the support plate 51 and the upper surface of the slope plate 52 are on the same plane. As a result, when the upper case 3 is placed on the tray 5, no gaps are generated between the lower edge of the upper case 3 and the support plate 51 and slope plate 52, as shown in Fig. 10. This makes it possible to utilize the strength of the upper case 3 without loss, and makes it possible to suppress buckling of the upper case 3 when the packaging members 1 in which the products P are packed are stacked.

[0045] Fig. 11 is a perspective view of the top cushioning material 42 used in the packaging member 1 according to the second embodiment of the present invention, as viewed from above. Fig. 12 is a perspective view of the top cushioning material 42 used in the packaging member 1 of the second embodiment, as viewed from the side of the surface that comes into contact with the product P. In Figs. 11 and 12 and the figures described below, the horizontal direction perpendicular to the extension direction of the slope plate 52 in a state in which the top cushioning material 42 is disposed below the slope plate 52 as a reinforcing base is defined as a first direction (arrow AA' direction). The extension direction of the slope plate 52 (horizontal direction perpendicular to the first direction) is defined as a second direction (arrow BB' direction).

[0046] In this embodiment, one upper cushioning material 42 as shown in Fig. 11 and Fig. 12 is disposed in the gap between the upper surface of the product P and the upper case 3. The upper cushioning material 42 is formed by folding a sheet material such as a cardboard sheet. The upper cushioning material 42 has a buffer plate 421, a pair of first support parts 422, and a pair of second support parts 423.

[0047] The buffer plate 421 is rectangular and divided into a first region 421a, a second region 421b, and a third region 421c by folding lines L1 and L2 parallel to the first direction. The buffer plate 421 is folded in a Z-shape in side view along folding lines L3 and L4 (second folding lines) parallel to the second direction. By folding the buffer plate 421 along the folding lines L3 and L4, the distance between the pair of first support poles 422 and the distance between the pair of second support poles 423 are adjusted to match the dimensions of the product P. The second region 421b is provided with a locking mechanism 428. The locking mechanism 428 is made of a cut-and-raised piece and a slit, and the cut-and-raised piece is inserted into the slit to hold the buffer plate 421 folded along the folding lines L3 and L4.

[0048] The pair of first support pillars 422 are formed by bending a sheet material connected to the edge of the buffer plate 421 on the first region 421a side into a rectangular tube shape, or by folding and adhering another sheet material. The configuration of other parts of the first support pillars 422 is similar to that of the first embodiment, so a description thereof will be omitted.

[0049] The pair of second support pillars 423 are formed by folding a sheet material connected to the edge of the buffer plate 421 on the third region 421c side into a square tube shape, or by folding and adhering another sheet material. The height of the second support pillars 423 is lower than that of the first support pillars 422. A pair of guide parts 423b protruding upward from both ends in the first direction are formed at the tips (upper surfaces in FIG. 12) of the pair of second support pillars 423. The distance between the pair of guide parts 423b is slightly larger than the width of the slope plate 52. When the upper surface cushioning material 42 is placed below the slope plate 52, the slope plate 52 fits between the pair of guide parts 423b. The configuration of other parts of the second support pillars 423 is the same as that of the first embodiment, so a description thereof will be omitted.

[0050] The following describes the procedure for opening the packaging member 1 of the second embodiment and removing the product P. The procedure for removing the upper case 3 from the tray-equipped pallet 2 and the procedure for removing the slope plate 52 from the tray 5 are the same as those in the first embodiment.

[0051] Next, the upper cushioning material 42 is changed from the shape (first shape) shown in Figures 12 and 13, which is set to match the shape of the product P, to a shape (second shape) that is set to be used as a reinforcing base for the slope plate 52.

[0052] Specifically, by releasing the locking mechanism 428 from the state in which the buffer plate 421 is folded in the first direction along the folding lines L3 and L4 as shown in Fig. 12 and Fig. 13, the buffer plate 421 is extended to a flat state as shown in Fig. 13. As a result, the distance between the pair of first support parts 422 and the distance between the pair of second support parts 423 are adjusted according to the use as a reinforcing base for the slope plate 52.

[0053] Next, from the state shown in Fig. 13, the buffer plate 421 is folded along the folding lines L1 and L2 into a Z-shape in side view, and the insertion pieces 425 of the first region 421a are inserted into the insertion holes 426a and 426b (see Fig. 11), so that the buffer plate 421 is held in a state folded in the second direction as shown in Fig. 14. This allows the distance between the first support portion 422 and the second support portion 423 to be adjusted in accordance with use as a reinforcing base for the slope plate 52.

[0054] Fig. 15 is an exploded perspective view of the tray-equipped pallet 2, the slope plate 52, and the upper cushioning material 42 placed below the slope plate 52 of the packaging member 1 of the second embodiment. As shown in Fig. 15, the flap 5b of the tray 5 is tilted outward. Then, the upper cushioning material 42 folded into the shape of Fig. 14 (second shape) is placed below the slope plate 52 as a reinforcing base. In this embodiment, a positioning hole 54 is formed in the flap 5b of the tray 5 near the through hole 8a, into which the positioning protrusion 52a (see Fig. 4) of the slope plate 52 is fitted.

[0055] Fig. 16 is a partial perspective view of a connecting portion between the flap 5b and the upper cushioning material 42 when attaching the slope plate 52 to the tray 5 in the packaging member 1 of the second embodiment. Fig. 17 is an enlarged view of the vicinity of the through hole 8a and the positioning hole 54 in Fig. 16. As shown in Fig. 16, an insertion piece 54a is formed on the opening edge of the positioning hole 54.

[0056] Next, as shown in Fig. 15, the positioning protrusion 52a of the slope plate 52 removed from the tray 5 is fitted into the positioning hole 54 of the flap 5b. At this time, as shown in Fig. 17, the insertion piece 54a is bent downward and inserted into the opening 422b formed in the first support part 422 of the upper cushioning material 42 together with the positioning protrusion 52a. As a result, the flap 5b, slope plate 52, and upper cushioning material 42 are positioned relative to each other.

[0057] In this manner, a slope from the tray-equipped pallet 2 to the floor surface is completed as shown in Fig. 18. Fig. 19 is an enlarged perspective view of the contact portion between the slope plate 52 and the second support portion 423 of the upper cushioning material 42 in Fig. 18.

[0058] 19, the slope plate 52 is held in a fitted state between a pair of guide portions 423b formed on the second support portion 423. The pair of guide portions 423b contact both ends in the width direction of the slope plate 52. This makes it possible to effectively suppress positional deviation of the slope plate 52 in the width direction (direction of arrow AA').

[0059] According to the configuration of this embodiment, as in the first embodiment, the number of materials required for the slope that is used only when opening the packaging material 1 can be reduced. As a result, this leads to a reduction in the amount of waste and recovery of the used packaging material 1, and is environmentally friendly. In addition, since the slope plate 52 is packed in a state where it is overlapped on the bottom surface 5a of the tray 5, no packing space is required for the slope plate 52. In addition, by engaging the positioning protrusion 52a of the slope plate 52 with the engagement hole 53 on the bottom surface 5a, it is possible to prevent the slope plate 52 from shifting or falling off.

[0060] In this embodiment, by using one upper cushioning material 42 as a reinforcing base for the slope plate 52, the number of times that the upper cushioning material 42 and the tray 5 (flap 5b) need to be aligned is reduced to one time, and the work time can be shortened. In addition, since the pair of first support parts 422 and second support parts 423 of the upper cushioning material 42 are integrated, the distance between the left and right slope plates 52 is always constant, and deviation between the slope plates 52 is suppressed. Therefore, the product P can be stably moved from the tray-equipped pallet 2 to the floor surface.

[0061] Furthermore, by forming the guide portion 423b on the second support portion 423, it is possible to stably support the vicinity of the tip of the slope plate 52, which is prone to misalignment. Therefore, it is possible to further suppress misalignment between the two slope plates 52.

[0062] Furthermore, by fitting the positioning protrusion 52a of the slope plate 52 into the positioning hole 54 formed in the flap 5b of the tray 5, and fitting it together with the insertion piece 54a formed on the opening edge of the positioning hole 54 into the opening 422b formed in the first support portion 422 of the upper cushioning material 42, the alignment of the slope plate 52 with the tray 5 and the upper cushioning material 42 can be easily and reliably achieved.

[0063] In this embodiment, when the upper cushioning material 42 is used as a reinforcing base for the slope plate 52, the cushioning plate 421 is extended in the first direction (the direction of the arrow AA') as shown in FIG. 14. However, for example, by folding the cushioning plate 421 from the state (first shape) of FIG. 12 along the fold lines L1 and L2, the cushioning plate 421 may be folded in the first direction along the fold lines L3 and L4 as shown in FIG. 20.

[0064] In other words, by selectively using the state of Figure 14 and the state of Figure 20, the distance between a pair of first support pillars 422 and the distance between a pair of second support pillars 423 can be adjusted in two stages to match the distance between the slope plates 52 (the position of the casters 60 of the product P).

[0065] In addition, the present invention is not limited to the above-mentioned embodiments, and various modifications are possible within the scope of the present invention. For example, in the above-mentioned embodiments, the upper surface cushioning material 42 is used as a reinforcing base for the slope plate 52, but the present invention is not limited to this, and the side surface cushioning material 41 may be used as a reinforcing base for the slope plate 52.

[0066] In addition, in the first embodiment, the two upper cushioning materials 42 have the same shape, but the two upper cushioning materials 42 may have different shapes as long as the relationship between the first support portion 422 and the second support portion 423 is the same. Furthermore, by changing the positions of the fold lines L1, L2 formed on the buffer plate 241 in the first and second embodiments, or the fold lines L3, L4 formed on the buffer plate 241 in the second embodiment, the upper cushioning materials 42 can be folded to match the shape of the product P and the dimensions and inclination of the slope plate 52.

[0067] In addition, in each of the above embodiments, the reinforcing member 427 is arranged on the inside of the first support portion 422 of the upper surface cushioning material 42, but instead of or in addition to the first support portion 422, the reinforcing member 427 may be arranged on the inside of the second support portion 423 or the third support portion 424. [Industrial Applicability]
