Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the above dry vacuum pump unit is usually housed in a package of a wooden frame and is stored and transported to the site. However, the dry vacuum pump unit has various sizes according to the specifications, and conventionally, the packaging size has been designed according to these sizes. As a result, it has ended up with an inventory of more than 200 types of packages, which has been a huge burden in terms of resources, costs, and operation management.

[0005] The package prepares a packing box according to the size of the object to be packed (dry vacuum pump unit) so that the object to be packed is not damaged or injured by vibration or impact during transportation, and covers the object to be packed. However, if the object to be packed is not a hexahedron in shape, or even if it is a hexahedron, there are bulges around it, etc., there will inevitably be a gap between the packing box and the object to be packed. In that case, it is necessary to fill the gap with a cushioning material and devise a way to fill the gap so that the object to be packed does not vibrate or move in the packing box.

[0006] Furthermore, the above-mentioned problems are not limited to dry vacuum pump units, but also apply to other types of pumps, fluid machinery such as compressors, turbines, and blowers, and to all types of packaged objects of various sizes.

Embodiments for Carrying Out the Invention

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, as an object to be packed, a pump (specifically, a dry vacuum pump unit) is exemplified, but the object to be packed is not necessarily limited to the pump.

[0013] (First Embodiment) FIG. 1 is a perspective view of the package 1 according to the first embodiment. FIG. 2 is an exploded perspective view of the package 1 according to the first embodiment. As shown in these figures, the package 1 includes a packing box 2 that houses the object to be packed 100, a pallet 3 that supports the packing box 2, and a band 4 that fixes the pallet 3 and the packing box 2.

[0014] In the following description, an XYZ orthogonal coordinate system is set, and the positional relationship of each member may be described while referring to this XYZ orthogonal coordinate system. The X-axis direction is the short side direction of the package 1 in the form of a rectangular box in plan view. The Y-axis direction is the longitudinal direction of the package 1 in the form of a rectangular box in plan view. The Z-axis direction is the height direction of the package 1 in the form of a rectangular box in plan view.

[0015] The object to be packed 100 in the present embodiment is rectangular box-shaped as shown in FIG. 2, and a plurality of protrusions 101 are provided on the upper surface, and a plurality of casters 102 are provided on the bottom surface. As the protrusion 101, an eye nut used when lifting the object to be packed 100 (pump) can be exemplified, but it is not limited to the eye nut.

[0016] Furthermore, in this embodiment, the packaging box 2 and pallet 3 are made from corrugated cardboard. When stacking the packaging bodies 1, the bottom wall 11 and lid 12 may also be made of corrugated cardboard. While the pallet 3 may be made of wood, resin, or metal, it is preferable to use a paper pallet, making the entire structure from paper, from the viewpoint of resource conservation, low cost, and ease of operation and management. Note that when the pallet 3 is made of paper, it is not limited to corrugated cardboard. Band 4 is typically a resin band, but it may also be string, wire, chain, etc. Furthermore, as for the corrugated cardboard, it is preferable to use corrugated cardboard that has increased compressive strength by using a core with higher strength than that used in ordinary corrugated cardboard (so-called reinforced corrugated cardboard). Examples of such reinforced corrugated cardboard include cases where the core uses paper with a significantly higher ring crush value than ordinary cores (around scp120), or where the liner uses a liner with a higher basis weight (around 400g basis weight) than ordinary liners (around 200g basis weight).

[0017] The pallet 3 comprises a top plate 3a, a bottom plate 3b, and a plurality of support columns 3c positioned between the top plate 3a and the bottom plate 3b. The top plate 3a and the bottom plate 3b are formed in the shape of rectangular plates in plan view. The support columns 3c are positioned at least at the four corners of the top plate 3a and the bottom plate 3b, and at the midpoints in the longitudinal direction of the top plate 3a and the bottom plate 3b. The upper ends of the support columns 3c are fixed to the top plate 3a by adhesive or the like, and the lower ends of the support columns 3c are fixed to the bottom plate 3b by adhesive or the like.

[0018] The top plate 3a and bottom plate 3b are formed, for example, by stacking and gluing together one or more rectangular pieces of corrugated cardboard. The support columns 3c are formed, for example, by stacking multiple pieces of corrugated cardboard to form a block, which is then housed in a box-shaped corrugated cardboard box. The pallet 3 is close to the ground and may get wet in some places, so it is advisable to use waterproof corrugated cardboard. The support columns 3c can be made by stacking multiple pieces of corrugated cardboard to form a block, as long as water resistance can be ensured, or another piece of corrugated cardboard can be attached as a lid to the cross section where the corrugated shape appears stepped to prevent water from entering.

[0019] Pallet 3 has a space 3d that penetrates in the X-axis direction between the support columns 3c. A band 4 that restrains the packaging box 2 and pallet 3 is passed through the space 3d, and the tip of a forklift or the like is inserted into it when transporting the package 1.

[0020] The packaging box 2 comprises a side wall portion 10, a bottom wall portion 11, and a lid portion 12. As shown in Figure 2, the side wall portion 10 is formed in a rectangular shape in plan view and is formed in a frame shape that surrounds the four sides of the object to be packaged 100. The side wall portion 10 may be separated into multiple parts (for example, two L-shaped parts in plan view) depending on the size of the object to be packaged 100.

[0021] The bottom wall portion 11 is formed in the shape of a rectangular box with a bottom that opens at the top. A support base 30 for supporting the packaged item 100 is fixed to the inside of the bottom wall portion 11 by adhesive or the like. The support base 30 is also made of corrugated cardboard. The support base 30 comprises a first beam member 31 and a second beam member 32 combined with the first beam member 31.

[0022] The first beam members 31 are provided in pairs, spaced apart in the Y-axis direction, and extend parallel to the X-axis direction. The first beam members 31 are, for example, blocks made of multiple stacked cardboard boxes. To support heavy objects, these blocks should be installed with the overlapping surfaces of the cardboard boxes perpendicular to the ground. The pair of first beam members 31 are positioned inward in the Y-axis direction of the casters 102 provided on the bottom surface of the packaged object 100, and support the bottom surface of the packaged object 100 while keeping the casters 102 lifted away from the bottom wall 11. As a result, the first beam members 31 buffer vibrations from the ground or other objects below the packaged object 100, preventing vibrations from being directly transmitted to the packaged object 100. Furthermore, the first beam members 31 prevent the load of the packaged object 100 from concentrating on a part of the bottom wall 11, thus maintaining the strength of the bottom wall 11.

[0023] The second girders 32 are provided in pairs, spaced apart in the X-axis direction, and extend parallel to the Y-axis direction. The second girders 32 are formed from the first angle members 21, which will be described later. The pair of second girders 32 are assembled in a grid pattern on the upper surfaces of the pair of first girders 31 by adhesive or the like. The pair of second girders 32 contact both sides of the packaged object 100 in the X-axis direction, thereby suppressing vibrations in the X-axis direction during transport.

[0024] The lid portion 12 is formed in the shape of a top-opening box with a rectangular shape in plan view, with the bottom opening. As shown in Figure 1, the lid portion 12 closes the upper end opening of the side wall portion 10 and surrounds the upper end opening of the side wall portion 10 from all four sides. The bottom wall portion 11 also closes the lower end opening of the side wall portion 10 and surrounds the lower end opening of the side wall portion 10 from all four sides.

[0025] Figure 3 is an internal configuration diagram of the packaging body 1 according to the first embodiment, viewed from the X-axis direction. Figure 4 is an internal configuration diagram of the packaging body 1 according to the first embodiment, viewed from the Z-axis direction. As shown in these figures, the inside of the packaging box 2 is provided with an internal fixing member 20 for securing the item to be packaged 100. Reference numeral 103 in the figures indicates a suction pipe provided on the upper surface of the item to be packaged 100 (dry vacuum pump unit).

[0026] As shown in Figure 4, the box-internal fixing member 20 is fixed at both ends to the opposing surfaces of the side wall portion 10. In this embodiment, the side wall portion 10 has a pair of first side wall portions 10a facing each other in the longitudinal direction (Y-axis direction) and a pair of second side wall portions 10b facing each other in the short direction (X-axis direction), and the box-internal fixing member 20 is fixed to the opposing surfaces of the pair of second side wall portions 10b by fixing members 5 such as tapping screws.

[0027] Figure 5 is a perspective view of the box-internal fixing member 20 according to the first embodiment. Figure 6 is an exploded perspective view of the box-internal fixing member 20 according to the first embodiment. As shown in Figure 5, the box-internal fixing member 20 comprises a first angle member 21 formed by stacking multiple sheets of paper material and bending them into an L-shape, and a pair of second angle members 22 formed by stacking multiple sheets of paper material and bending them into an L-shape, with both ends of the first angle member 21 fixed to the opposing surfaces of the side wall 10. The paper material forming the first angle member 21 and the second angle member may be ordinary corrugated cardboard, or other L-shaped angle material made of paper, and it is not necessary to stack multiple sheets of the paper material as long as sufficient strength is met. The paper material refers to, for example, a material made by laminating, bonding, and press-molding 100% pulp cardboard.

[0028] As shown in Figure 6, the first angle member 21 is formed in an L-shape when viewed from the X-axis direction and extends in the X-axis direction in the same shape. The first angle member 21 comprises a horizontal portion 21a and a vertical portion 21b bent relative to the horizontal portion 21a. The horizontal portion 21a is the part that abuts against the upper surface of the object to be packaged 100, as shown in Figures 3 and 4. The vertical portion 21b is the part that abuts against the side surface of the projection 101, as shown in Figures 3 and 4.

[0029] As shown in Figure 6, the second angle member 22 is formed in an L-shape when viewed from the Z-axis direction and extends in the Z-axis direction in the same shape. The second angle member 22 comprises a portion 22a that faces the first angle member and a portion 22b that faces a side wall and is bent relative to the first angle member 21. The portion 22a that faces the first angle member faces the vertical portion 21b of the first angle member 21 and is fixed with a fixing member 6 such as a stapler (see Figure 5). The dimension of the portion 22a that faces the first angle member in the Z-axis direction is approximately the same as the dimension of the vertical portion 21b in the Z-axis direction.

[0030] The side wall opposing portion 22b is positioned at the X-axis end of the horizontal portion 21a. The side wall opposing portion 22b faces the side wall portion 10 (second side wall portion 10b) of the packaging box 2. The Y-axis dimension of the side wall opposing portion 22b is approximately the same as the Y-axis dimension of the horizontal portion 21a. The side wall opposing portion 22b is supported on the horizontal portion 21a of the first angle member 21. This allows the second angle member 22 to support the vertical portion 21b even when a bending load is applied to the vertical portion 21b of the first angle member 21 that approaches the horizontal portion 21a. In other words, the load on the side wall opposing portion 22b can be supported by the thickness of both the vertical portion 21b and the first angle member opposing portion 22a. The first angle member 21 and the second angle member 22 are assembled as described above, but they may be integrally molded using pulp molding or the like, as long as the strength requirements are met.

[0031] The box-internal fixing member 20 with the above configuration is arranged inside the packaging box 2 as shown in Figures 3 and 4. In this embodiment, a first projection 101a and a second projection 101b are provided on the upper surface of the object to be packaged 100, spaced apart in the Y-axis direction. The box-internal fixing member 20 comprises a first box-internal fixing member 20a that abuts against the upper surface of the object to be packaged 100 and the first projection 101a, and a second box-internal fixing member 20b that abuts against the upper surface of the object to be packaged 100 and the second projection 101b.

[0032] The first box-internal fixing member 20a and the second box-internal fixing member 20b contact the upper surface of the packaged object 100, thereby suppressing vibrations in the Z-axis direction during transport of the packaged object 100. Furthermore, the first box-internal fixing member 20a abuts against the +Y side surface of the first projection 101a, which is located on the -Y side. The second box-internal fixing member 20b abuts against the -Y side surface of the second projection 101b, which is located on the +Y side, rather than the +Y side. As a result, the first box-internal fixing member 20a and the second box-internal fixing member 20b suppress vibrations in the Y-axis direction during the transport of the packaged object 100.

[0033] As described above, the packaging body 1 according to this embodiment comprises a packaging box 2 formed from corrugated cardboard and having side walls 10 surrounding the four sides of the object to be packaged 100, and an internal fixing member 20 whose ends are fixed to the opposing surfaces of the side walls 10. The internal fixing member 20 comprises a first angle material 21 made by stacking multiple sheets of paper material and bending them into an L shape, and a pair of second angle materials 22 made by stacking multiple sheets of paper material and bending them into an L shape, with both ends of the first angle material 21 fixed to the opposing surfaces of the side walls 10. With this configuration, the packaging box 2 can be fixed at any position within the packaging box 2 by the internal fixing member 20, even if the size of the packaging box 2 does not need to be matched to the size of the packaging object 100. As a result, the number of packaging box sizes can be reduced from more than 200 to just a few.

[0034] Furthermore, as described in Patent Document 1, the packaged object 100 (pump) is packaged as a single unit comprising the pump, motor, connecting equipment, and control equipment, and the center of gravity is not necessarily at the center of the packaged object 100. Therefore, by making it possible to fix the packaged object 100 at any position within the packaging box 2, the center of gravity can be placed in the center of the packaged body 1. As a result, the packaged body 1 can be transported without the forklift operator having to constantly take care to prevent the packaged body 1 from tilting during forklift movement. In addition, by using cardboard for the internal fixing member 20 of the box, it can withstand external forces during transport, is easy to manufacture, and can also be easily disposed of on-site.

[0035] Furthermore, by using the lower second beam member 32 to restrain the movement of the heavy object 100 in the X-axis direction, and the upper first angle member 21 to restrain the movement of the object 100 in the Y-axis direction, it becomes unnecessary to fill gaps with cushioning material to prevent the object 100 from vibrating or moving within the packaging body 1. Note that the first angle material 21 and the second angle material 22 may be made by cutting and joining the same angle material, or they may be made from different angle materials as long as they meet the above specifications. For example, the thickness or number of overlapping angle materials may differ. When cutting and joining angle materials, unlike wood, the packaging box 2 is made of reinforced cardboard, so the internal fixing member 20 can be installed even if the dimension in the Y-axis direction is slightly larger. Furthermore, even if the first angle material 21 is smaller, it can be used because the required dimension in the Y-axis direction can be changed simply by changing how the second angle material 22 is attached.

[0036] Furthermore, in this embodiment, a projection 101 is provided on the upper surface of the object to be packaged 100, and the box fixing member 20 is in contact with the upper surface of the object to be packaged 100 and the side surface of the projection 101. With this configuration, vibrations during transport of the object to be packaged 100 can be suppressed by utilizing the projection 101 provided on the upper surface of the object to be packaged 100.

[0037] Furthermore, in this embodiment, the upper surface of the object to be packaged 100 is provided with a first projection 101a and a second projection 101b, and the box-internal fixing member 20 includes a first box-internal fixing member 20a that abuts against the upper surface of the object to be packaged 100 and the +Y side (first side) of the first projection 101a, and a second box-internal fixing member 20b that abuts against the upper surface of the object to be packaged 100 and the -Y side (second side) of the second projection 101b which is facing the opposite direction to the first side. With this configuration, vibrations of the object to be packaged 100 in two directions (Y-axis direction and Z-axis direction) can be suppressed by the two box-internal fixing members 20. Note that the first box-internal fixing member 20a and the second box-internal fixing member 20b may be arranged so as to sandwich the first projection 101a and the second projection 101b from the outside in the Y-axis direction, rather than from the inside in the Y-axis direction.

[0038] Furthermore, in this embodiment, casters 102 are provided on the bottom surface of the item to be packaged 100, and the packaging box 2 is made of cardboard and includes a support base 30 that supports the bottom surface of the item to be packaged 100 with its protrusions raised. With this configuration, it is possible to suppress the item to be packaged 100 from swaying on the bottom wall portion 11 of the packaging box 2 due to the casters 102. In this case, the first beam member 31 can also dampen vibrations from below, such as from the ground, so that vibrations are not directly transmitted to the item to be packaged 100.

[0039] Furthermore, this embodiment includes a pallet 3 for supporting the packaging box 2 and a band 4 for securing the pallet 3 and the packaging box 2. This configuration makes it easier to transport the packaging box 2 together with the pallet 3 using a forklift or the like.

[0040] Furthermore, in this embodiment, the object to be packaged 100 is a pump. This configuration facilitates the packaging and transport of pumps of various sizes.

[0041] Thus, according to the above embodiment, a packaging body 1 that is resource-saving, low-cost, and easy to operate and manage can be provided.

[0042] (Second Embodiment) Next, a second embodiment of the present invention will be described. In the following description, components identical or equivalent to those in the above-described embodiment will be denoted by the same reference numerals, and their descriptions will be simplified or omitted.

[0043] Figure 7 is an internal configuration diagram of the packaging body 1 according to the second embodiment, viewed from the X-axis direction. Figure 8 is an internal configuration diagram of the packaging body 1 according to the second embodiment, viewed from the Z-axis direction. As shown in these figures, in the second embodiment, the box-internal fixing members 20 are provided in pairs, sandwiching both sides of the projection 101.

[0044] The packaging body 1 of the second embodiment accommodates a larger object 100 than that of the first embodiment. For this reason, the packaging box 2 is further provided with a third internal fixing member 20c and a fourth internal fixing member 20d.

[0045] The third box-internal fixing member 20c is in contact with the upper surface of the packaged object 100 and the -Y side of the first projection 101a. In other words, the first projection 101a is sandwiched between the first box-internal fixing member 20a and the third box-internal fixing member 20c in the Y-axis direction.

[0046] The fourth internal box fixing member 20d is in contact with the upper surface of the packaged object 100 and the +Y side of the second projection 101b. In other words, the second projection 101b is sandwiched in the Y-axis direction between the second internal box fixing member 20b and the fourth internal box fixing member 20d.

[0047] In addition, in the second embodiment, one additional first beam member 31 is provided for the support base 30, bringing the total to three, in order to support the large packaged object 100. Furthermore, in the second embodiment, a reinforcing section 3e is provided to prevent the top plate 3a of the pallet 3 from deforming under the weight of the packaged object 100. Similar to the first beam member 31 described above, the reinforcing section 3e is, for example, a block made of multiple stacked cardboard boxes, and it is preferable to install the block so that the overlapping surfaces of the cardboard boxes are perpendicular to the ground.

[0048] As described above, in the second embodiment, the box fixing members 20 are provided in pairs, sandwiching both sides of the projection 101. With this configuration, even if the packaged object 100 is large, vibrations during transport can be sufficiently suppressed.

[0049] (Third embodiment) Next, a third embodiment of the present invention will be described. In the following description, components identical or equivalent to those in the above-described embodiments will be denoted by the same reference numerals, and their descriptions will be simplified or omitted.

[0050] Figure 9 is an internal configuration diagram of the packaging body 1 according to the third embodiment, viewed from the X-axis direction. Figure 10 is an internal configuration diagram of the packaging body 1 according to the third embodiment, viewed from the Z-axis direction. As shown in these figures, in the third embodiment, the packaging box 2 contains a ramp member 40 made of cardboard and used when unloading the packaged object 100.

[0051] The ramp member 40 has a right-angled triangular shape when viewed from the X-axis direction. When the ramp member 40 is placed on the same installation surface as the pallet 3 (shown by the dashed line in Figure 9), it has a height approximately the same as the pallet 3. Furthermore, by unfolding a part 11a of the bottom wall 11, a continuous slope can be formed on the ramp member 40. This ramp member 40 is housed inside the packing box 2, for example, by being placed on the box fixing member 20. Since the direction of movement of the item to be packed 100 by the casters 102 is in the Y-axis direction, if the ramp member 40 is transported and installed in the Y-axis direction from its packed state, a continuous slope can be formed because the height of the ramp member 40 is approximately the same as the height of the pallet 3. This allows for smooth packing, transport, storage, and unloading of the item to be packed 100.

[0052] In the third embodiment, the object to be packaged 100 is lightweight, and in order to facilitate the removal of the object to be packaged 100 by casters 102, the support base 30 is not provided. Instead, as a means of suppressing vibration in the X-axis direction during the transport of the object to be packaged 100, a pair of first angle members 21 are arranged in a grid pattern around the first box internal fixing member 20a and the second box internal fixing member 20b.

[0053] As shown in Figure 10, the pair of first angle members 21 have their horizontal portions 21a fixed to the lower surfaces of the first box-internal fixing member 20a and the second box-internal fixing member 20b, and their vertical portions 21b abut against both sides of the packaged object 100 in the X-axis direction. This makes it possible to suppress vibrations during transport of the packaged object 100 in the X-axis direction even without a support base 30. Although not shown, the pair of first angle members 21 are fixed to the first box-internal fixing member 20a and the second box-internal fixing member 20b by fixing members such as tapping screws or staples.

[0054] Figure 11 is a perspective view of the slope member 40 according to the third embodiment. As shown in Figure 11, the slope member 40 comprises a sloping portion 41 and a base portion 42 that supports the sloping portion 41.

[0055] Figure 12 is an exploded perspective view of the base portion 42 according to the third embodiment. Figure 13 is a perspective view showing the first step in assembling the slope member 40 according to the third embodiment. Figure 14 is a perspective view showing the second step in assembling the slope member 40 according to the third embodiment.

[0056] As shown in Figure 12, the base portion 42 comprises a first groove-shaped member 43 and a second groove-shaped member 44. The first groove-shaped member 43 comprises a flat bottom portion 43a and a pair of right-angled triangular side portions 43b that rise from the bottom portion 43a. Multiple slits 43c are formed in the pair of side portions 43b. In addition, an insertion portion 43d is formed in the bottom portion 43a that extends to the rear of the pair of side portions 43b. This first groove-shaped member 43 is fixed in a triple configuration so that the side portions 43b meet face to face.

[0057] The second groove-shaped member 44 is formed in a U-shape, or more specifically, a J-shape, when viewed from the side. In other words, the second groove-shaped member 44 is shorter at the front end and longer at the rear end than the first groove-shaped member 43. The second groove-shaped member 44 has a slit 44a that can be inserted into the slit 43c of the first groove-shaped member 43. The second groove-shaped member 44 is positioned laterally to engage with the three consecutive first groove-shaped members 43. The second groove-shaped member 44 comprises a second groove-shaped member 44A positioned on the front end side of the first groove-shaped member 43 and a second groove-shaped member 44B positioned on the rear end side of the first groove-shaped member 43.

[0058] As shown in Figure 13, the rear end 41b of the inclined portion 41 is folded back toward the front end 41a, allowing the insertion portion 43d of the base portion 42 to be inserted. Furthermore, as shown in Figure 14, the front end 41a of the inclined portion 41 is foldable toward the rear end 41b and is inserted into the slit 43c of the first grooved member 43 with which the second grooved member 44A engages. Based on the above, the slope member 40 shown in Figure 12 can be assembled. However, the assembly structure of the slope member 40 is not limited to this.

[0059] As described above, in the third embodiment, as shown in Figure 9, casters 102 are provided on the bottom of the packaged object 100, and the packaging box 2 is made of cardboard and contains a ramp member 40 used when unloading the packaged object 100. With this configuration, by using the ramp member 40, it becomes easier to unload relatively lightweight packaged objects 100 from the packaging box 2, unlike heavy packaged objects 100 that weigh nearly 1 ton and are lifted and transported by crane using the protrusions 101 for safety management purposes.

[0060] Furthermore, in this embodiment, a pair of first angle members 21 are arranged in a grid pattern to multiple box-internal fixing members 20. With this configuration, vibrations during transport of the packaged object 100 in the X-axis direction can be suppressed even without a support base 30.

[0061] While preferred embodiments of the present invention have been described and explained above, it should be understood that these are illustrative and should not be considered limiting. Additions, omissions, substitutions, and other modifications can be made without departing from the scope of the invention. Therefore, the present invention should not be considered limited by the foregoing description, but rather limited by the claims.

[0062] For example, in the above embodiment, an eye nut was exemplified as the projection 101, but the configuration is not limited to this. For example, other projection structures (for example, an intake pipe indicated by reference numeral 103) may be used as the projection 101. Any other projection structure that is located on the upper part of the packaged object 100 and that can come into horizontal contact with the vertical portion 21b of the first angle member 21 of the box fixing member 20 is acceptable as the projection 101.

[0063] Furthermore, in the above embodiment, for example, the packaging body 1 suppresses movement in the Y-axis direction at the top of the object to be packaged 100 and movement in the X-axis direction at the bottom of the object to be packaged 100, but the configuration is not limited to this. For example, in the example shown in Figure 4, movement in the Y-axis direction of the object to be packaged 100 may be suppressed by having the internal fixing member 20 hit the short side of the object to be packaged 100. Also, when viewed in the vertical direction, the long side may be fixed at the top of the object to be packaged 100 and the short side at the bottom of the object to be packaged 100, and furthermore, if the internal fixing member 20 or support base 30 is applied to all four sides of the object to be packaged 100, there may be no restriction on the height in the vertical direction. However, if the height is the same, the internal fixing member 20 will not be able to be fixed inside the packaging box 2, so this should be avoided. Furthermore, if the projection 101 is absent, the box fixing member 20, which is located on the Y-axis side of the projection 101, may be positioned so as to strike the upper side of the box in the X-axis direction, and the other side in the Y-axis direction, as shown in the examples in Figures 7 and 8, and the second beam member 32 may also be positioned to fix the Y-axis direction, such that either the upper or lower part of the hexahedron of the packaged object 100 is fixed in the X-axis direction.

[0064] Furthermore, for example, in the above embodiment, the internal fixing member 20 was brought into contact with the side surface of the projection 101, but if there is no projection 101, the internal fixing member 20 may be brought into direct contact with the side surface of the object to be packaged 100. Furthermore, for example, the use of the internal fixing member 20 can also be applied to the packaging body 1, which has a narrow width in the X-axis direction, as shown in Figures 4 and 8. Furthermore, for example, the box fixing member 20 may be brought into contact with the inside of the two protrusions 101, the outside of the two protrusions 101, and both sides of the two protrusions 101. These configurations are applicable to any of the above embodiments, and their substitutions and combinations are free. [Explanation of Symbols]
