Description

Technical Field

[0001] The present invention relates to a packaging component having a pallet with a tray and an upper box, and more particularly to a packaging component packaged with a slope for moving packaged objects from a product placement surface of the pallet with a tray. Background Art

[0002] In the past, when a product (packaged object) with a certain weight, such as an electronic device, is packaged in a pallet with a tray and an upper box (packaging components) for transportation and storage, the product placement surface of the pallet with a tray has a step relative to the ground. Therefore, the following method is generally used: a slope is formed on the step part, and in the case of a product with casters, the product is moved directly on the slope; in the case of a product without casters or when the caster part is in a packaged state, the product is placed on a trolley with casters and then moved on the slope.

[0003] Here, if the slope is a plate-shaped member, there is a problem that the slope may be bent, deformed, or broken when the product is heavy. Summary of the invention

[0004] An object of the present invention is to provide a packaging member that can be packaged together with a slope for moving a packaged object and that can suppress an increase in the size of the packaging member and an increase in the amount of material used.

[0005] The first packaging component of the present invention comprises: a pallet with a tray, comprising: a pallet for placing packaged objects; and a pallet fixed to the lower surface of the pallet; an upper box, which is a cylinder with an open bottom and covers the side surfaces and the upper surface of the packaged objects; a buffer component, which is placed between the packaged objects and the upper box; and a ramp plate, which is connected to the pallet with the pallet when the packaged objects placed on the pallet are moved, and the buffer component is arranged as a reinforcement platform below the ramp plate connected to the pallet with the pallet.

[0006] According to the first configuration of the present invention, by using the buffer component as a reinforcing platform of the ramp plate, it is not necessary to package the reinforcing platform together as another component, so the volume of the packaging component can be reduced. Therefore, since it can be transported and stored with the minimum packaging volume, the transportation and storage costs can be reduced. In addition, the material usage of the packaging component itself can be reduced, which also helps to reduce the cost of the packaging component. In addition, the components required for the ramp that is only used when the packaging component is opened can be reduced. As a result, it helps to reduce the amount of discarded and recycled packaging components after use, and the environmental response is also excellent. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 1 is a perspective view showing a state where a product P is arranged in a packaging member 1 according to a first embodiment of the present invention. Figure 1 As shown, the packaging component 1 is composed of a pallet 2 with a tray, an upper box 3 and a buffer component 4.

[0009] The pallet 2 with a tray is composed of a tray 5 and a tray 6 fixed to the lower surface of the tray 5. The tray 5 has a rectangular bottom surface 5a (see Figure 2 ), and four flaps 5b connected to the four sides of the bottom surface 5a. A through hole 8a is formed at a predetermined position of the flap 5b.

[0010] The pallet 6 includes, for example, a plurality of pillars 6a formed by bending a corrugated cardboard, and a top plate 6b and a bottom plate 6c fixed to the upper and lower surfaces of each pillar 6a, and an arm insertion hole 9 for inserting an arm of a forklift or a manual pallet truck (pallet transport trolley) is formed between each pillar 6a. The top plate 6b is fixed to the bottom surface 5a of the pallet 5 using nails, screws, etc. (not shown). In addition, the pallet 6 can also be made of wood.

[0011] The pallet 2 with a tray also serves as the bottom surface of the packaging member 1. After the product P is packaged, there is no need to further place the packaging member 1 on the pallet, so that the packaging and transportation of large products are facilitated.

[0012] The upper box 3 is a rectangular parallelepiped with an open bottom, and covers the side and upper surface of the product (packaged object) P. A through hole 8b is formed at the lower end of the upper box 3 at a position overlapping the through hole 8a of the folding wing 5b. The pallet 2 with the tray is connected to the upper box 3 as a whole by inserting a fastener (not shown) in a state where the through holes 8a and 8b overlap. In addition, in the present embodiment, the upper box 3 in which the cylindrical side surface and the top surface are formed as a whole is used, but the upper box 3 that can be separated into the side surface and the box-shaped top surface can also be used.

[0013] The buffer member 4 is arranged in the gap between the product P and the upper box 3 to protect the product P from external impact. The buffer member 4 is formed by bending the corrugated cardboard into a predetermined shape. The buffer member 4 includes a side buffer 41 arranged on the side of the product P and an upper surface buffer 42 arranged on the upper surface of the product P.

[0014] The side cushion members 41 are arranged in the vertical direction so as to cover the four corners of the side surface of the product P. A predetermined gap is formed between the side cushion members 41 and the flap 5b, and the lower end of the upper box 3 is inserted into the gap. Two upper surface cushion members 42 are arranged side by side on the upper surface of the product P. The detailed structure of the upper surface cushion members 42 will be described later.

[0015] Figure 2 2 is a perspective view of a tray 5 of a pallet 2 with a tray constituting a packaging member 1 according to the first embodiment. Figure 2 As shown, a pair of support plates 51 and a pair of slope plates 52 are stacked on the bottom surface 5 a of the tray 5 .

[0016] The support plate 51 is provided along two opposite sides ( Figure 2 The support plate 51 is fixed to the bottom surface 5a. The support plate 51 is connected to the casters 60 (see Fig. 9 The ramp plate 52 is arranged side by side between a pair of support plates 51. The ramp plate 52 is detachable relative to the bottom surface 5a.

[0017] Figure 3 It means from Figure 2 A perspective view of the tray 5 with the ramp plate 52 removed. Figure 4 FIG. 5 is a three-dimensional view of the ramp plate 52 viewed from the back side. Figure 3 As shown in FIG. 1 , two engaging holes 53 are formed in the portion of the bottom surface 5a that overlaps with the ramp plate 52. Figure 4 As shown, positioning protrusions 52 a are formed on the back side of the ramp plate 52 .

[0018] When the ramp plate 52 is overlapped with the bottom surface 5a of the pallet 5, the positioning protrusion 52a formed on the back side of the ramp plate 52 is engaged with the engaging hole 53 of the bottom surface 5a. Thus, the ramp plate 52 can be accurately installed at a predetermined position on the bottom surface 5a. In addition, the ramp plate 52 can be prevented from being deviated or falling off due to vibration or impact during transportation.

[0019] Figure 5 The upper surface buffer 42 placed on the upper surface of the product P is viewed from the contact surface side with the product P. The upper surface buffer 42 is formed by bending a sheet such as a corrugated cardboard. The upper surface buffer 42 includes a buffer plate 421, a first support portion 422, a second support portion 423, and a third support portion 424.

[0020] The buffer plate 421 is rectangular and is divided into a first area 421a, a second area 421b, and a third area 421c by fold lines L1 and L2. An insertion piece 425 is formed in the first area 421a. Insertion holes 426a and 426b are formed in the second area 421b and the third area 421c, respectively.

[0021] The first support part 422 is formed by bending a sheet material provided continuously with the end edge of the first region 421a of the buffer plate 421 into a square tube shape, or by bending and bonding another sheet material. Figure 5 The upper surface of the first support 422 is formed with an inclined surface 422a that is inclined downward toward the second support 423. An opening 422b is formed on the inclined surface 422a. The interior of the first support 422 is filled with a reinforcing member 427 formed by stacking corrugated cardboard in a horizontal direction.

[0022] The reinforcing member 427 is stacked in such a way that the grain direction of the corrugated cardboard (the extension direction of the thin tubes formed by the flat plate and the corrugated plate) becomes the vertical direction. As a result, when the upper surface buffer 42 is used as a reinforcing base of the ramp plate 52 as described later, the reinforcing member 427 is difficult to deform, and the strength of the first support part 422 can be improved. In addition, when the upper surface buffer 42 is placed on the upper surface of the product P, the cushioning of the first support part 422 against the impact from the side direction can be improved.

[0023] The second support part 423 is formed by bending a sheet material provided continuously with the end edge of the third region 421c of the buffer plate 421 into a square tube shape or by bending and bonding another sheet material. The height of the second support part 423 is lower than that of the first support part 422. Figure 5The upper surface of the first support portion 422 is formed with an inclined surface 423a inclined in the same direction as the inclined surface 422a of the first support portion 422. The inclination angles of the inclined surfaces 422a and 423a are substantially the same as the inclination angle of the ramp plate 52 when the ramp plate 52 is used.

[0024] The third support part 424 is formed by bending a sheet material continuously provided at the end edge of the first region 421a of the buffer plate 421 orthogonal to the first support part 422 into a square tube shape, or by bending and bonding another sheet material. The third support part 424 is arranged along substantially the entire region of the end edge of the buffer plate 421 from the first support part 422 to the second support part 423 in a manner orthogonal to the first support part 422 and the second support part 423. The height of the third support part 424 is lower than that of the first support part 422 and higher than that of the second support part 423.

[0025] In the packaging member 1 of this embodiment, when the product P is moved from the pallet 2 with a tray using the ramp plate 52, the upper surface buffer member 42 can be used as a reinforcement base for the ramp plate 52. Figure 5 In the upper surface buffer 42 of the shape (first shape) shown in FIG, the interval between the first support portion 422 and the second support portion 423 is set according to the shape of the upper surface of the product P. Therefore, when the upper surface buffer 42 is used as a reinforcing platform, the interval between the first support portion 422 and the second support portion 423 needs to be adjusted.

[0026] Figure 6 as well as Figure 7 4 is a diagram showing the bending steps when the upper surface buffer member 42 is used as a reinforcement base of the ramp plate 52. Figure 6 As shown, the buffer plate 421 is valley-folded along the fold line L1 and mountain-folded along the fold line L2. Thus, the first area 421a, the second area 421b, and the third area 421c of the buffer plate 421 are folded into a Z-shape in side view.

[0027] In addition, if Figure 7 As shown, the second area 421b and the third area 421c are overlapped with the first area 421a. At this time, the insertion hole 426a of the second area 421b overlaps the insertion hole 426b of the third area 421c. And, by inserting the insertion piece 425 of the first area 421a into the insertion holes 426a and 426b, the buffer plate 421 is kept in the folded state. Figure 7 In the upper surface buffer part 42 of the shape (second shape), the interval between the first support portion 422 and the second support portion 423 is as follows: when used as a reinforcement platform for the ramp plate 52, the inclined surface 422a of the first support portion 422 and the inclined surface 423a of the second support portion 423 are in contact with the back side of the ramp plate 52.

[0028] That is, by folding the buffer plate 421 along the folding lines L1 and L2 (first folding lines) perpendicular to the extending direction of the ramp plate 52 or stretching the folded state, the interval between the first support portion 422 and the second support portion 423 can be changed to be set according to the shape of the product P. Figure 5 The first support portion 422 and the second support portion 423 are spaced apart in accordance with the use of the ramp plate 52 as a reinforcement platform set Figure 7 shape (second shape).

[0029] Figure 8 This is a perspective view showing a state in which the ramp plate 52 connected to the flap 5 b is removed from the tray 5 of the pallet 2 with a tray in the packaging member 1 of the first embodiment and the upper surface cushion material 42 is placed below the ramp plate 52 as a reinforcement base. Fig. 9 2 is a perspective view showing a state where the product P is moved from the pallet 2 with a tray using the ramp plate 52. Figure 8 as well as Fig. 9 , the steps of opening the packaging component 1 and taking out the product P are described.

[0030] When the packaging member 1 is opened, after removing the fasteners (not shown) inserted into the through holes 8a and 8b, the upper box 3 (see Figure 1 ). Then, the side cushioning member 41 and the upper surface cushioning member 42 are removed, and the flap 5b is tilted outward.

[0031] Next, the ramp 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 load of the product P is not applied to the ramp 52. In addition, a gap is formed between the ramp 52 and the product P due to the casters 60. Therefore, the ramp 52 is lifted to release the positioning protrusion 52a (see Figure 4 ) is engaged with the engaging hole 53 of the bottom surface 5a and pulled out in the horizontal direction, thereby making it possible to easily remove the ramp plate 52.

[0032] Next, the removed ramp plate 52 is connected to the pallet 2 with a tray, and the upper surface buffer 42 is placed as a reinforcement platform under the ramp plate 52. Specifically, the positioning protrusion 52a of the ramp plate 52 is inserted into the through hole 8a of the flap 5b. In this way, the ramp plate 52 is positioned relative to the pallet 2 with a tray.

[0033] Next, Figure 7The upper surface buffer 42 bent as shown is placed under the ramp plate 52 with the buffer plate 421 facing downward. The upper surface buffer 42 is arranged so that the first support column 422 is close to the pallet 2 with the tray and the second support column 423 is away from the pallet 2 with the tray. At this time, the positioning protrusion 52a of the ramp plate 52 is inserted into the opening 422b of the first support column 422 formed in the upper surface buffer 42 through the through hole 8a.

[0034] Thus, the ramp plate 52 and the upper surface buffer 42 are positioned, and the inclined surfaces 422a and 423a of the first support 422 and the second support 423 are in contact with the lower surface of the ramp plate 52. In addition, the third support 424 is arranged along the outer edge of the ramp plate 52. A portion of the third support 424 protrudes upward from the ramp plate 52. By doing so, the ramp plate 52 is completed. Figure 8 The ramp from the pallet 2 with the tray to the ground is shown.

[0035] Moreover, if Fig. 9 As shown, the caster 60 of the product P is moved from the support plate 51 to the ramp plate 52, and the product P is moved from the pallet 2 with the tray to the ground along the ramp plate 52.

[0036] In the present embodiment, the upper surface buffer 42 is used as a reinforcing platform for the ramp plate 52. Thus, it is not necessary to package the reinforcing platform as a separate component, and the volume of the packaging component 1 can be reduced. Therefore, since it can be transported and stored with a minimum packaging volume, the transportation and storage costs can be reduced. In addition, the amount of material used in the packaging component 1 itself can be reduced, which also contributes to the cost reduction of the packaging component 1. In addition, the components required for the ramp that is only used when the packaging component 1 is opened can be reduced. As a result, it helps to reduce the amount of waste and recycling of the used packaging component 1, and the environmental response is also excellent.

[0037] In addition, the upper surface buffer 42 can change the interval between the first support portion 422 and the second support portion 423 by bending the buffer plate 421. Therefore, when the upper surface buffer 42 is used as a buffer or as a reinforcement base of the ramp plate 52, the interval between the first support portion 422 and the second support portion 423 can be appropriately adjusted.

[0038] In addition, when the upper surface buffer 42 is arranged below the ramp plate 52, the third support portion 424 is arranged along the outer edge of the ramp plate 52, and a portion of the third support portion 424 protrudes above the ramp plate 52. Thus, the third support portion 424 functions as a fall-off prevention guide that prevents the caster 60 from falling off the ramp plate 52.

[0039] In addition, since the ramp plate 52 is packed in a state overlapping with the bottom surface 5a of the tray 5, there is no need for a packing space for the ramp plate 52. In addition, by engaging the positioning protrusion 52a of the ramp plate 52 with the engagement hole 53 of the bottom surface 5a, the ramp plate 52 can be prevented from deviating or falling off.

[0040] In addition, by engaging the positioning protrusion 52a of the ramp plate 52 with the through hole 8a for installing the fastener formed on the folding wing 5b of the tray 5 and the opening portion 422b of the first support portion 422 formed on the upper surface buffer 42, the ramp plate 52 can also be easily aligned with the tray 5 and the upper surface buffer 42.

[0041] In addition, when the ramp plate 52 is overlapped with the bottom surface 5a of the tray 5, the upper surface of the support plate 51 and the upper surface of the ramp plate 52 are on the same plane. Fig.10 As shown, there is no gap between the lower edge of the upper box 3 and the support plate 51 and the slope plate 52. Therefore, the strength of the upper box 3 can be used without loss, and deformation of the upper box 3 can be suppressed when the packaging members 1 packaged with the product P are stacked.

[0042] Fig.11 This is a perspective view of an upper surface cushioning material 42 used in a packaging member 1 according to a second embodiment of the present invention as seen from above. Fig.12 4 is a perspective view of the upper surface cushioning material 42 used in the packaging member 1 of the second embodiment, viewed from the contact surface side with the product P. Fig.11 , Fig.12 In the following figures, the horizontal direction perpendicular to the extending direction of the ramp plate 52 in the state where the upper surface buffer 42 is arranged as a reinforcement platform below the ramp plate 52 is referred to as the first direction (arrow AA' direction). In addition, the extending direction of the ramp plate 52 (horizontal direction perpendicular to the first direction) is referred to as the second direction (arrow BB' direction).

[0043] In this embodiment, Fig.11 as well as Fig.12 The upper surface buffer 42 shown in FIG. 1 is disposed in the gap between the upper surface of the product P and the upper box 3. The upper surface buffer 42 is formed by bending a sheet such as a corrugated cardboard. The upper surface buffer 42 includes a buffer plate 421, a pair of first support pillars 422, and a pair of second support pillars 423.

[0044] The buffer plate 421 is rectangular and is divided into a first area 421a, a second area 421b, and a third area 421c by fold lines L1 and L2 parallel to the first direction. In addition, it is folded into a Z shape when viewed from the side along fold lines L3 and L4 (second fold lines) parallel to the second direction. By folding the buffer plate 421 along the fold lines L3 and L4, the interval between the pair of first support pillars 422 and the interval between the pair of second support pillars 423 are adjusted according to the size of the product P. A locking mechanism 428 is provided in the second area 421b. The locking mechanism 428 includes a cut and bent piece and a slit, and by inserting the cut and bent piece into the slit, the buffer plate 421 is kept in a state of being folded along the fold lines L3 and L4.

[0045] The pair of first pillars 422 are formed by bending a sheet provided continuously at the edge of the first region 421a of the buffer plate 421 into a square tube or by bending and bonding another sheet. The other parts of the first pillars 422 are similar to those of the first embodiment, and thus their description is omitted.

[0046] The pair of second pillars 423 are formed by bending a sheet material provided continuously with the end edge of the third region 421c of the buffer plate 421 into a square tube shape or by bending and bonding another sheet material. The height of the second pillars 423 is lower than that of the first pillars 422. At the tops ( Fig.12 A pair of guide portions 423b protruding upward from both ends in the first direction are formed on the upper surface of the second support column 423. The interval between the pair of guide portions 423b is slightly larger than the width of the ramp plate 52. When the upper surface buffer 42 is placed under the ramp plate 52, the ramp plate 52 is fitted between the pair of guide portions 423b. The other parts of the second support column 423 are constructed in the same manner as in the first embodiment, so the description is omitted.

[0047] Hereinafter, the procedure of opening the packaging member 1 of the second embodiment and taking out the product P will be described. The procedure of removing the upper box 3 from the pallet 2 with a tray and the procedure of removing the ramp plate 52 from the tray 5 are the same as those of the first embodiment.

[0048] Next, the upper surface buffer 42 is set according to the shape of the product P. Fig.12 as well as Fig.13 The shape (first shape) is changed to a shape (second shape) set according to the use as a reinforcement base of the ramp plate 52.

[0049] Specifically, the buffer plate 421 is folded along the folding lines L3 and L4 in the first direction. Fig.12 The locking mechanism 428 is released, thereby Fig.13As shown, the buffer plate 421 is extended to a flat state. Thus, the intervals between the pair of first support portions 422 and the pair of second support portions 423 are adjusted according to the use as a reinforcement base of the ramp plate 52.

[0050] Next, from Fig.13 The buffer plate 421 is bent along the fold lines L1 and L2 into a Z shape when viewed from the side, and the insertion piece 425 of the first area 421a is inserted into the insertion holes 426a and 426b (both refer to Fig.11 ), thus Fig.14 As shown in FIG. 1 , the buffer plate 421 is held in a folded state in the second direction. Thus, the interval between the first support portion 422 and the second support portion 423 is adjusted in accordance with the use of the ramp plate 52 as a reinforcement base.

[0051] Fig.15 FIG. 2 is an exploded perspective view of the tray 2 with a tray of the packaging component 1 according to the second embodiment, the ramp plate 52, and the upper surface buffer member 42 placed below the ramp plate 52. Fig.15 As shown, the flap 5b of the tray 5 is tilted outward. Fig.14 The upper surface buffer member 42 of the shape (second shape) is placed under the ramp plate 52 as a reinforcement platform. In this embodiment, a positioning protrusion 52a (see FIG. 5 ) for the ramp plate 52 is formed near the through hole 8a on the flap 5b of the tray 5. Figure 4 ) is embedded in the positioning hole 54.

[0052] Fig.16 It is a partial perspective view of the connection portion between the flap 5 b and the upper surface cushion material 42 when the ramp plate 52 is attached to the tray 5 in the packaging member 1 of the second embodiment. Fig.17 yes Fig.16 The through hole 8a and the enlarged view of the vicinity of the positioning hole 54 are shown. Fig.16 As shown, an insertion piece 54 a is formed at the opening edge of the positioning hole 54 .

[0053] Then, if Fig.15 As shown in FIG. 5 , the positioning protrusion 52a of the ramp plate 52 removed from the tray 5 is inserted into the positioning hole 54 of the flap 5b. Fig.17 As shown, the insertion piece 54a is bent downward and inserted together with the positioning protrusion 52a into the opening 422b formed in the first support portion 422 of the upper surface cushioning member 42. Thus, the flap 5b, the slope plate 52 and the upper surface cushioning member 42 are positioned relative to each other.

[0054] As shown above, complete Fig.18 Such a slope from the pallet 2 with the tray to the ground is shown in FIG. Fig.19 yes Fig.18FIG. 5 is an enlarged perspective view of a contact portion between the ramp plate 52 and the second support portion 423 of the upper surface buffer member 42 .

[0055] like Fig.19 As shown, the ramp plate 52 is kept embedded between a pair of guide portions 423b formed on the second support portion 423. The pair of guide portions 423b are in contact with both side ends in the width direction of the ramp plate 52. Thus, the position deviation of the ramp plate 52 in the width direction (arrow AA' direction) can be effectively suppressed.

[0056] According to the configuration of this embodiment, similarly to the first embodiment, it is possible to reduce the components required for the ramp that is used only when the packaging member 1 is opened. As a result, it is possible to contribute to the reduction of the amount of discarded and recycled packaging members 1 after use, and it is also excellent in environmental protection. In addition, the ramp plate 52 is packaged in a state overlapping with the bottom surface 5a of the tray 5, so there is no need for a packaging space for the ramp plate 52. In addition, by engaging the positioning protrusion 52a of the ramp plate 52 with the engaging hole 53 of the bottom surface 5a, it is possible to prevent the ramp plate 52 from deviating or falling off.

[0057] In addition, in this embodiment, by using one upper surface buffer 42 as a reinforcing platform for the ramp plate 52, the number of alignments between the upper surface buffer 42 and the pallet 5 (flap 5b) can be reduced to one, which can shorten the operation time. In addition, since a pair of first support portions 422 and second support portions 423 of the upper surface buffer 42 are integrated, the interval between the left and right ramp plates 52 is always constant, which can suppress the deviation between the ramp plates 52. Therefore, the product P can be stably moved from the pallet 2 with a pallet to the ground.

[0058] Furthermore, the guide portion 423 b is formed on the second support portion 423 , so that the front end vicinity of the ramp plate 52 that is prone to positional deviation can be stably supported. Therefore, the deviation between the two ramp plates 52 can be further suppressed.

[0059] In addition, the positioning protrusion 52a of the ramp plate 52 is engaged with the positioning hole 54 formed on the folding wing 5b of the tray 5, and is engaged with the insertion piece 54a formed on the opening edge of the positioning hole 54 in the opening portion 422b of the first support portion 422 formed on the upper surface buffer 42, thereby enabling the ramp plate 52 to be easily and reliably aligned with the tray 5 and the upper surface buffer 42.

[0060] In addition, in this embodiment, when the upper surface buffer member 42 is used as a reinforcement base of the ramp plate 52, as shown in FIG. Fig.14 As shown in the figure, the buffer plate 421 is in a state of being extended in the first direction (the direction of the arrow AA′), but for example, it is also possible to Fig.12The buffer plate 421 is folded directly along the folding lines L1 and L2 in the state (first shape), thereby Fig. 20 As shown, the buffer plate 421 is in a state of being folded in the first direction along the folding lines L3 and L4.

[0061] That is, by distinguishing between Fig.14 Status and Fig. 20 In the state, the interval between a pair of first support portions 422 and the interval between a pair of second support portions 423 can be adjusted in two stages according to the interval between the ramp plates 52 (the position of the casters 60 of the product P).

[0062] In addition, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the scope of the present invention. For example, in the above-mentioned embodiments, the example of using the upper surface buffer 42 as a reinforcing platform of the ramp plate 52 is shown, but the present invention is not limited to this, and the side buffer 41 can also be used as a reinforcing platform of the ramp plate 52.

[0063] In addition, in the first embodiment, the two upper surface buffers 42 are made to have the same shape, but the two upper surface buffers 42 may also have different shapes as long as the relationship between the first support portion 422 and the second support portion 423 is the same. In addition, by changing the positions of the fold lines L1 and L2 formed on the buffer plate 241 of the first and second embodiments or the fold lines L3 and L4 formed on the buffer plate 241 of the second embodiment, the upper surface buffer 42 can be folded according to the shape of the product P and the size and inclination of the ramp plate 52.

[0064] In addition, in the above embodiment, the reinforcing component 427 is arranged on the inner side of the first support portion 422 of the upper surface buffer 42, but the reinforcing component 427 can also be arranged on the inner side of the second support portion 423 or the third support portion 424 instead of or in addition to the first support portion 422.

[0065] The present invention can be used for a packaging component having a pallet with a tray and an upper box. By utilizing the present invention, a packaging component can be provided that can be packaged together with a slope for moving the packaged object and can suppress the enlargement of the packaging component and the increase in the amount of material used.
