[0019] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that in the following description, a pump (specifically, a dry vacuum pump unit) will be used as an example of a packaging target. However, the packaging target is not limited to the pump.(First Embodiment)

[0020] FIG. 1 is a perspective view of a package 1 according to a first embodiment. FIG. 2 is an exploded perspective view of the package 1 according to the first embodiment.

[0021] As shown in the drawings, the package 1 includes a packaging box 2 that accommodates a packaging target 100, a pallet 3 that supports the packaging box 2, and bands 4 that fix the pallet 3 and the packaging box 2.

[0022] Note that in the following description, the XYZ Cartesian coordinate system may be set, and a positional relationship of each member may be described with reference to the XYZ Cartesian coordinate system. An X-axis direction is a transverse direction of the package 1 having a rectangular box-like shape as seen in a plan view. A Y-axis direction is a longitudinal direction of the package 1 having the rectangular box-like shape as seen in the plan view. A Z-axis direction is a height direction of the package 1 having the rectangular box-like shape as seen in the plan view.

[0023] As shown in FIG. 2, the packaging target 100 of the present embodiment has a rectangular box-like shape, a plurality of protruding portions 101 are provided at an upper surface thereof, and a plurality of casters 102 are provided at a bottom surface thereof. Examples of the protruding portions 101 include an eye nut which is used to lift the packaging target 100 (a pump), but the protruding portions 101 are not limited to eye nuts.

[0024] In addition, in the present embodiment, the packaging box 2 and the pallet 3 are formed of corrugated cardboard. Note that in a case where the packages 1 are to be stacked, bottom wall portions 11 and lid portions 12 may also be formed of corrugated cardboard. Although the pallet 3 may be a wooden pallet, a resin pallet, or a metal pallet, from the viewpoint of resource-saving, low cost, and easy operation management, it is preferable that the entire package is formed of paper with the pallet 3 being a paper pallet. Note that in a case where the pallet 3 is formed of paper, the material thereof is not limited to corrugated cardboard.

[0025] The bands 4 are typically resin bands, but may be strings, wires, chains, or the like. In addition, as the corrugated cardboard, corrugated cardboard (so-called reinforced corrugated cardboard) in which a medium, of which the strength is higher than the strength of a medium used in normal corrugated cardboard, is used to increase compression strength is preferable. Regarding the reinforced corrugated cardboard, for example, there are a case where paper having a ring crush value obviously higher than the ring crush value of a normal medium (like scp 120) is used for a medium and a case where a liner having a basis weight (a basis weight in a 400 to 500 gsm range) higher than the basis weight (a basis weight in a 200 to 300 gsm range) of a normal liner is used as a liner.

[0026] The pallet 3 includes a top plate 3a, a bottom plate 3b, and a plurality of columns 3c disposed between the top plate 3a and the bottom plate 3b. Each of the top plate 3a and the bottom plate 3b is formed in a rectangular plate-like shape as seen in a plan view. The columns 3c are disposed at at least four corners between the top plate 3a and the bottom plate 3b and intermediate portions in the longitudinal direction between the top plate 3a and the bottom plate 3b. Upper ends of the columns 3c are fixed to the top plate 3a through adhesion or the like, and lower ends of the columns 3c are fixed to the bottom plate 3b through adhesion or the like.

[0027] Each of the top plate 3a and the bottom plate 3b is formed, for example, by stacking and bonding one or a plurality of sheets of corrugated cardboard each having a rectangular shape as seen in a plan view. The columns 3c are formed by accommodating, for example, a plurality of sheets of corrugated cardboard stacked into a block-like shape into box-shaped corrugated cardboard. Since a portion corresponding to the pallet 3 is close to the ground and may get wet although depending on the location, it is favorable to use waterproof corrugated cardboard. In addition, as long as a waterproof property can be secured, the columns 3c may be a plurality of sheets of corrugated cardboard stacked into a block-like shape or other corrugated cardboard may be attached to a sectional portion, at which a wave shape can be seen as a stepped shape, like a lid so that there is no infiltration of water.

[0028] In the pallet 3, a space portion 3d that penetrates the pallet 3 in the X-axis direction is formed between the columns 3c.

[0029] The bands 4 that bind the packaging box 2 and the pallet 3 are wound through the space portion 3d, and lift tips of a forklift or the like are inserted into the space portion 3d at the time of transportation of the package 1.

[0030] The packaging box 2 includes a side wall portion 10, the bottom wall portion 11, and the lid portion 12. As shown in FIG. 2, the side wall portion 10 is formed in a rectangular shape as seen in a plan view and is formed in a frame shape that surrounds four sides of the packaging target 100. Note that the side wall portion 10 may be separable into a plurality of parts (for example, two parts each having an L-like shape as seen in a plan view) in accordance with the size of the packaging target 100.

[0031] The bottom wall portion 11 is formed in a bottomed box-like shape of which an upper side is open and that is rectangular as seen in a plan view. A supporting base 30 that supports the packaging target 100 is fixed inside of the bottom wall portion 11 through adhesion or the like. The supporting base 30 is also formed of corrugated cardboard. The supporting base 30 includes first beam materials 31 and second beam materials 32 combined with the first beam materials 31.

[0032] A pair of the first beam materials 31 is provided with the first beam materials 31 separated from each other in the Y-axis direction and the first beam materials 31 extend in the X-axis direction to be parallel with each other. The first beam materials 31 are, for example, block bodies formed by stacking a plurality of sheets of corrugated cardboard. The block bodies may be installed in such a direction that corrugated cardboard surfaces stacked onto each other are perpendicular to the ground, so that the block bodies support a heavy object. The pair of first beam materials 31 is disposed inward of the casters 102, which are provided at the bottom surface of the packaging target 100, in the Y-axis direction and supports the bottom surface of the packaging target 100 in a state where the casters 102 are not in contact with the bottom wall portion 11. Accordingly, the first beam materials 31 reduce the influence of vibration from a lower side, such as vibration from the ground, on the packaging target 100, and it is possible to prevent vibration from being directly transmitted to the packaging target 100. Furthermore, since it is possible to prevent concentration of the load of the packaging target 100 on a part of the bottom wall portion 11 with the first beam materials 31, the strength of the bottom wall portion 11 can be maintained.

[0033] A pair of the second beam materials 32 is provided with the second beam materials 32 separated from each other in the X-axis direction and the second beam materials 32 extend in the Y-axis direction to be parallel with each other. The second beam materials 32 are formed of first angle materials 21 which will be described later. The pair of second beam materials 32 is combined with upper surfaces of the pair of first beam materials 31 through adhesion or the like to form a hash-like shape. The pair of second beam materials 32 abuts against both side surfaces of the packaging target 100 in the X-axis direction to suppress vibration in the X-axis direction at the time of transportation.

[0034] The lid portion 12 is formed in a topped box-like shape of which a lower side is open and that is rectangular as seen in a plan view. As shown in FIG. 1, the lid portion 12 blocks an upper end opening portion of the side wall portion 10 and surrounds the upper end opening portion of the side wall portion 10 from four sides. Note that the bottom wall portion 11 also blocks a lower end opening portion of the side wall portion 10 and surrounds the lower end opening portion of the side wall portion 10 from four sides.

[0035] FIG. 3 is an internal configuration view of the package 1 according to the first embodiment as seen in the X-axis direction. FIG. 4 is an internal configuration view of the package 1 according to the first embodiment as seen in the Z-axis direction.

[0036] As shown in the drawings, in-box fixation members 20 that fix the packaging target 100 are provided in the packaging box 2. Note that a reference numeral "103" in the drawing represents a suction pipe provided at an upper surface of the packaging target 100 (a dry vacuum pump unit).

[0037] As shown in FIG. 4, both ends of each in-box fixation member 20 are fixed to facing surfaces of the side wall portion 10. In the present embodiment, the side wall portion 10 includes a pair of first side wall portions 10a that face each other in the longitudinal direction (the Y-axis direction) and a pair of second side wall portions 10b that face each other in the transverse direction (the X-axis direction), and the in-box fixation members 20 are fixed to facing surfaces of the pair of second side wall portions 10b by fixation members 5 such as tapping screws or the like.

[0038] FIG. 5 is a perspective view of the in-box fixation member 20 according to the first embodiment. FIG. 6 is an exploded perspective view of the in-box fixation member 20 according to the first embodiment.

[0039] As shown in FIG. 5, the in-box fixation member 20 includes the first angle material 21, in which a plurality of paper members is stacked and bent into an L-like shape, and a pair of second angle materials 22, in each of which a plurality of paper members is stacked and bent into an L-like shape and through which both ends of the first angle material 21 are fixed to the facing surfaces of the side wall portion 10. Note that regarding the paper members forming the first angle material 21 and the second angle materials 22, L-shaped angle materials formed of normal corrugated cardboard or other paper and it is not necessary to stack a plurality of the paper members as long as a satisfactory strength is achieved. Note that a paper member refers to, for example, a member obtained by laminating and bonding 100% pulp paper sheets and performing press forming.

[0040] As shown in FIG. 6, the first angle material 21 is formed to have an L-like shape as seen in the X-axis direction and extends in the X-axis direction in the L-like shape. The first angle material 21 includes a horizontal portion 21a and a perpendicular portion 21b bent with respect to the horizontal portion 21a. The horizontal portion 21a is a portion that abuts against an upper surface of the packaging target 100 as shown in FIGS. 3 and 4. In addition, the perpendicular portion 21b is a portion that abuts against a side surface of the protruding portion 101 as shown in FIGS. 3 and 4.

[0041] As shown in FIG. 6, each second angle material 22 is formed in an L-like shape as seen in the Z-axis direction and extends in the Z-axis direction in the L-like shape. The second angle material 22 includes a first angle material facing portion 22a and a side wall facing portion 22b bent with respect to the first angle material 21. The first angle material facing portion 22a faces the perpendicular portion 21b of the first angle material 21 and is fixed by fixation members 6 such as tacker needles or the like (refer to FIG. 5). Note that the dimension of the first angle material facing portion 22a in the Z-axis direction is approximately equal to the dimension of the perpendicular portion 21b in the Z-axis direction.

[0042] The side wall facing portion 22b is disposed at an end portion of the horizontal portion 21a in the X-axis direction. The side wall facing portion 22b faces the side wall portion 10 (the second side wall portion 10b) of the packaging box 2. A dimension of the side wall facing portion 22b in the Y-axis direction is approximately equal to a dimension of the horizontal portion 21a in the Y-axis direction. Note that the side wall facing portion 22b is supported on the horizontal portion 21a of the first angle material 21. Accordingly, even in a case where a bending load toward the horizontal portion 21a is applied to the perpendicular portion 21b of the first angle material 21, the second angle material 22 can support the perpendicular portion 21b. That is, a load applied to the side wall facing portion 22b can be supported by the thicknesses of both the perpendicular portion 21b and the first angle material facing portion 22a. Note that although the first angle material 21 and the second angle material 22 are assembled as described above, the first angle material 21 and the second angle material 22 may be integrally molded through pulp molding or the like as long as a satisfactory strength is achieved.

[0043] The in-box fixation members 20 configured as described above are disposed in the packaging box 2 as shown in FIGS. 3 and 4. In the present embodiment, a first protruding portion 101a and a second protruding portion 101b are provided on the upper surface of the packaging target 100 to be separated from each other in the Y-axis direction. The in-box fixation members 20 include a first in-box fixation member 20a that abuts against the upper surface of the packaging target 100 and the first protruding portion 101a, and a second in-box fixation member 20b that abuts against the upper surface of the packaging target 100 and the second protruding portion 101b.

[0044] The first in-box fixation member 20a and the second in-box fixation member 20b abut against the upper surface of the packaging target 100 to suppress vibration of the packaging target 100 in the Z-axis direction at the time of transportation.

[0045] In addition, with respect to the first protruding portion 101a disposed on a -Y side, the first in-box fixation member 20a abuts against a side surface of the first protruding portion 101a on a +Y side. In addition, with respect to the second protruding portion 101b disposed on the +Y side, the second in-box fixation member 20b abuts against a side surface of the second protruding portion 101b that is on the -Y side instead of the +Y side, the -Y side being a side opposite to the +Y side. Accordingly, the first in-box fixation member 20a and the second in-box fixation member 20b suppress vibration of the packaging target 100 in the Y-axis direction at the time of transportation.

[0046] As described above, the package 1 according to the present embodiment includes the packaging box 2 that is formed of corrugated cardboard and that includes the side wall portion 10 surrounding four sides of the packaging target 100 and the in-box fixation members 20 each of which has both ends fixed to the facing surfaces of the side wall portion 10, and each in-box fixation member 20 includes the first angle material 21, in which a plurality of paper members is stacked and bent into an L-like shape, and the pair of second angle materials 22, in each of which a plurality of paper members is stacked and bent into an L-like shape, and through which both ends of the first angle material 21 are fixed to the facing surfaces of the side wall portion 10.

[0047] According to this configuration, it is possible to fix, by means of the in-box fixation members 20, the packaging target 100 at any position in the packaging box 2 even in a case where the size of the packaging box 2 does not match the packaging target 100. Accordingly, the number of the sizes of the packaging box 2 can be reduced to a several number from a number equal to or greater than 200.

[0048] Note that as described in Japanese Unexamined Patent Application, First Publication No. 2010-127120, the packaging target 100 (a pump) is packaged such that the pump, a motor, a machine that connects the pump and the motor to each other, and a control machine are packaged together with each other and the center of the packaging target 100 may not be the center of gravity of the packaging target 100. Therefore, in a case where it is possible to fix the packaging target 100 at any position in the packaging box 2, it is possible to set the position of the center of gravity at the center of the package 1. Therefore, it is possible for a forklift operator to transport the package 1 without paying attention such that the package 1 is not tilted while the package 1 is being moved by a forklift. In addition, since corrugated cardboard is used for the in-box fixation members 20, it is possible to withstand an external force during transportation, it is easy to manufacture the in-box fixation members 20, and it is easy to dispose of the in-box fixation members 20 on the site.

[0049] Furthermore, since movement of the packaging target 100, which is a heavy object, in the X-axis direction is suppressed by the second beam materials 32 on a lower side and the movement of the packaging target 100 in the Y-axis direction is suppressed by the first angle materials 21 on an upper side, it is not necessary to fill a gap with a buffer material to prevent the packaging target 100 from vibrating or moving in the package 1.

[0050] Note that the first angle material 21 and the second angle material 22 may be connected to each other after being cut from the same angle material and the first angle material 21 and the second angle material 22 may be separate angle materials as long as the above-described specifications are achieved. For example, there may be a difference in thicknesses of angle materials to be stacked or number of angle materials to be stacked. In a case where the angle materials are connected to each other after being cut, unlike a case where the angle materials are formed of wood, the in-box fixation members 20 can be attached even in a case where a dimension thereof in the Y-axis direction is slightly large since the packaging box 2 is formed of reinforced corrugated cardboard. Furthermore, even in a case where the first angle material 21 is small, the first angle material 21 can be used since it is possible to change a required dimension in the Y-axis direction only by changing a method of attaching the second angle material 22.

[0051] In addition, in the present embodiment, the protruding portion 101 is provided at the upper surface of the packaging target 100, and the in-box fixation members 20 abut against the upper surface of the packaging target 100 and the side surface of the protruding portion 101. According to this configuration, it is possible to suppress vibration of the packaging target 100 at the time of transportation by using the protruding portion 101 provided at the upper surface of the packaging target 100.

[0052] In addition, in the present embodiment, the first protruding portion 101a and the second protruding portion 101b are provided at the upper surface of the packaging target 100, and the in-box fixation members 20 include the first in-box fixation member 20a that abuts against the upper surface of the packaging target 100 and a side surface (a first side surface) of the first protruding portion 101a on the +Y side and the second in-box fixation member 20b that abuts against the upper surface of the packaging target 100 and a side surface (a second side surface) of the second protruding portion 101b on the -Y side, which is opposite to the first side surface. According to this configuration, it is possible to suppress vibration of the packaging target 100 in two directions (the Y-axis direction and the Z-axis direction) with two in-box fixation members 20. Note that the first in-box fixation member 20a and the second in-box fixation member 20b may be disposed such that the first protruding portion 101a and the second protruding portion 101b are interposed between the first in-box fixation member 20a and the second in-box fixation member 20b from outer sides in the Y-axis direction instead of from an inner side in the Y-axis direction.

[0053] In addition, in the present embodiment, the casters 102 are provided at the bottom surface of the packaging target 100, and the packaging box 2 includes the supporting base 30 that is formed of corrugated cardboard and that supports the bottom surface of the packaging target 100 in a state where the casters 102 are suspended. According to this configuration, it is possible to restrain the packaging target 100 from shaking on the bottom wall portion 11 of the packaging box 2 due to the casters 102. In addition, in this case, the first beam materials 31 reduce the influence of vibration from a lower side, such as vibration from the ground, and it is possible to prevent vibration from being directly transmitted to the packaging target 100.

[0054] In addition, in the present embodiment, the pallet 3 that supports the packaging box 2 and the bands 4 that fix the pallet 3 and the packaging box 2 are provided. According to this configuration, the packaging box 2 can be easily transported together with the pallet 3 by a forklift or the like.

[0055] In addition, in the present embodiment, the packaging target 100 is a pump. According to this configuration, it is easy to package and transport pumps of various sizes.

[0056] As described above, according to the present embodiment, it is possible to provide the package 1 that is resource-saving, low-cost, and easy to manage and operate.(Second Embodiment)

[0057] Next, a second embodiment of the present invention will be described. In the following description, the same or equivalent components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be simplified or omitted.

[0058] FIG. 7 is an internal configuration view of the package 1 according to the second embodiment as seen in the X-axis direction. FIG. 8 is an internal configuration view of the package 1 according to the second embodiment as seen in the Z-axis direction.

[0059] As shown in the drawings, in the second embodiment, a pair of the in-box fixation members 20 is provided with both side surfaces of the protruding portion 101 interposed between the pair of the in-box fixation members 20.

[0060] The package 1 of the second embodiment accommodates the packaging target 100 that is larger than that of the first embodiment. Therefore, a third in-box fixation member 20c and a fourth in-box fixation member 20d are additionally provided in the packaging box 2.

[0061] The third in-box fixation member 20c abuts against the upper surface of the packaging target 100 and a side surface of the first protruding portion 101a on the -Y side. That is, the first protruding portion 101a is interposed between the first in-box fixation member 20a and the third in-box fixation member 20c in the Y-axis direction.

[0062] The fourth in-box fixation member 20d abuts against the upper surface of the packaging target 100 and a side surface of the second protruding portion 101b on the +Y side. That is, the second protruding portion 101b is interposed between the second in-box fixation member 20b and the fourth in-box fixation member 20d in the Y-axis direction.

[0063] In addition, in the second embodiment, one first beam material 31 of the supporting base 30 is added to support the large packaging target 100, so that three first beam materials 31 are provided. In addition, in the second embodiment, a reinforcing portion 3e is provided so that the top plate 3a of the pallet 3 is not deformed due to the weight of the packaging target 100. The reinforcing portion 3e is, for example, a block body obtained by stacking a plurality of sheets of corrugated cardboard as with the first beam materials 31 described above and the block body may be installed in such a direction that corrugated cardboard surfaces stacked onto each other are perpendicular to the ground.

[0064] As described above, in the second embodiment described above, the pair of in-box fixation members 20 is provided with both side surfaces of the protruding portion 101 interposed between the pair of in-box fixation members 20. According to this configuration, even in a case where the packaging target 100 is large, vibration of the packaging target 100 at the time of transportation can be sufficiently suppressed.(Third Embodiment)

[0065] Next, a third embodiment of the present invention will be described. In the following description, the same or equivalent components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be simplified or omitted.

[0066] FIG. 9 is an internal configuration view of the package 1 according to the third embodiment as seen in the X-axis direction. FIG. 10 is an internal configuration view of the package 1 according to the third embodiment as seen in the Z-axis direction.

[0067] As shown in the drawings, in the third embodiment, the packaging box 2 accommodates a slope member 40 that is formed of corrugated cardboard and that is used in a case where the packaging target 100 is to be taken out.

[0068] The slope member 40 has a right-angled triangular shape as seen in the X-axis direction. The slope member 40 has approximately the same height as the height of the pallet 3 in a case where the slope member 40 is placed on the same installation surface as the pallet 3 (represented by two-dot chain lines in FIG. 9). In addition, it is possible to form an inclined surface, which is continuous to the slope member 40, by unfolding a portion 11a of the bottom wall portion 11. The slope member 40 is accommodated in the packaging box 2 by being, for example, placed on the in-box fixation members 20. Since a direction in which the packaging target 100 moves due to the casters 102 is the Y-axis direction, in a case where the slope member 40 in a packaged state is taken out in the Y-axis direction and installed as it is, a continuous inclined surface is formed since the height of the slope member 40 is approximately the same as the height of the pallet 3. As a result, the packaging, transportation, storage, and unloading of the packaging target 100 can be smoothly performed.

[0069] Note that in the third embodiment, the packaging target 100 is a lightweight object and the supporting base 30 is not provided so that the packaging target 100 can be easily taken out by means of the casters 102. Instead, as means for suppressing vibration of the packaging target 100 in the X-axis direction at the time of transportation, a pair of the first angle materials 21 is combined with the first in-box fixation member 20a and the second in-box fixation member 20b to form a hash-like shape.

[0070] As shown in FIG. 10, regarding the pair of first angle materials 21, the horizontal portions 21a thereof are fixed to lower surfaces of the first in-box fixation member 20a and the second in-box fixation member 20b, and the perpendicular portions 21b thereof abut against both side surfaces of the packaging target 100 in the X-axis direction. Accordingly, it is possible to suppress vibration of the packaging target 100 in the X-axis direction at the time of transportation even in a case where the supporting base 30 is not provided. Note that although not shown, the pair of first angle materials 21 is fixed to the first in-box fixation member 20a and the second in-box fixation member 20b by fixation members such as tapping screws, tacker needles, or the like.

[0071] FIG. 11 is a perspective view of the slope member 40 according to the third embodiment.

[0072] As shown in FIG. 11, the slope member 40 includes an inclined surface portion 41 and a base portion 42 that supports the inclined surface portion 41.

[0073] FIG. 12 is an exploded perspective view of the base portion 42 according to the third embodiment. FIG. 13 is a perspective view showing a first step in assembly of the slope member 40 according to the third embodiment. FIG. 14 is a perspective view showing a second step in assembly of the slope member 40 according to the third embodiment.

[0074] As shown in FIG. 12, the base portion 42 includes first groove-shaped members 43 and second groove-shaped members 44. Each of the first groove-shaped members 43 includes a flat plate-shaped bottom portion 43a and a pair of side portions 43b each of which is erected on the bottom portion 43a and each of which has a right-angled triangular shape as seen from a lateral side. A plurality of slits 43c are formed at the pair of side portions 43b. In addition, an insertion portion 43d that extends behind the pair of side portions 43b is formed at the bottom portion 43a. Three first groove-shaped members 43 are fixed to each other in series such that surfaces of the side portions 43b come into contact with each other.

[0075] Each of the second groove-shaped members 44 is formed in a C-like shape as seen from a lateral side (more specifically, a J-like shape as seen from a lateral side). That is, the second groove-shaped members 44 are short on a side close to tip ends of the first groove-shaped members 43 and are long on a side close to rear ends of the first groove-shaped members 43. Slits 44a that can be inserted into the slits 43c of the first groove-shaped members 43 are formed at the second groove-shaped members 44. The second groove-shaped members 44 are disposed in a lateral direction to be engaged with the three first groove-shaped members 43 fixed in series. The second groove-shaped members 44 include a second groove-shaped member 44A that is disposed on the side close to the tip ends of the first groove-shaped members 43 and a second groove-shaped member 44B that is disposed on the side close to the rear ends of the first groove-shaped members 43.

[0076] As shown in FIG. 13, a rear end portion 41b of the inclined surface portion 41 is folded toward a front end portion 41a side, and the insertion portion 43d of the base portion 42 can be inserted into the rear end portion 41b.

[0077] In addition, as shown in FIG. 14, the front end portion 41a of the inclined surface portion 41 can be folded toward the rear end portion 41b side, and is inserted into the slits 43c of the first groove-shaped members 43 with which the second groove-shaped members 44A are engaged.

[0078] It is possible to assemble the slope member 40 shown in FIG. 12 in this manner. Note that the assembly structure of the slope member 40 is not limited thereto.

[0079] As described above, in the third embodiment, as shown in FIG. 9, the casters 102 are provided at the bottom surface of the packaging target 100, and the packaging box 2 accommodates the slope member 40 that is formed of corrugated cardboard and that is used in a case where the packaging target 100 is to be taken out. According to this configuration, since the slope member 40 is used, from safety management point of view, it is easy to take, out of the packaging box 2, the relatively light packing target 100 that is different from the packaging target 100 that is to be hoisted and transported by a crane by using the protruding portions 101 and that has a weight of nearly 1 ton in heavy case.

[0080] In addition, in the present embodiment, the pair of first angle materials 21 is combined with a plurality of the in-box fixation members 20 to form a hash-like shape. According to this configuration, it is possible to suppress vibration of the packaging target 100 in the X-axis direction at the time of transportation even in a case where the supporting base 30 is not provided.

[0081] Although preferred embodiments of the present invention have been described and explained above, it should be understood that these embodiments are exemplary and should not be considered as limiting. Additions, omissions, substitutions, and other changes can be made without departing from the scope of the present invention. Accordingly, the present invention should not be considered as being limited by the foregoing description, and is only limited by the scope of the appended claims.

[0082] For example, in the above-described embodiments, an eye nut has been used as an example of the protruding portion 101. However, the present invention is not limited to such a configuration. For example, another protruding structure (for example, an intake pipe represented by a reference numeral "103") may be used as the protruding portion 101. Any other protruding structure may be adopted as long as the protruding portion 101 is on an upper portion of the packaging target 100 and the perpendicular portion 21b of the first angle material 21 of the in-box fixation member 20 can come into contact with the protruding portion 101 in a horizontal direction.

[0083] In addition, for example, in the case of the package 1 in the above-described embodiments, movement of the packaging target 100 in the Y-axis direction is suppressed at an upper portion thereof and movement of the packaging target 100 in the X-axis direction is suppressed at a lower portion thereof. However, the present invention is not limited to such a configuration. For example, in the example shown in FIG. 4, the movement of the packaging target 100 in the Y-axis direction may be suppressed with the in-box fixation members 20 abutting against short sides of the packaging target 100. In addition, long sides of the upper portion of the packaging target 100 as seen in a vertical direction may be fixed and short sides of a lower portion of the packaging target 100 may be fixed. Furthermore, there may be no limit on a height in the vertical direction as long as the in-box fixation members 20 or the supporting base 30 abuts against four sides of the packaging target 100. Note that since the in-box fixation members 20 cannot be fixed in the packaging box 2 in a case where the in-box fixation members 20 have the same height as the packaging box 2, it is favorable that the in-box fixation members 20 do not have the same height as the packaging box 2. In addition, in a case where the protruding portions 101 are not to be provided, for example, the in-box fixation members 20 that are disposed outward of the protruding portions 101 in the Y-axis direction in an example shown in FIGS. 7 and 8 may be disposed to abut against upper portion side surfaces of the packaging target 100 in the X-axis direction and the second beam materials 32 may fix the packaging target 100 in the Y-axis direction so that any one of an upper portion and a lower portion of a hexahedron of the packaging target 100 is fixed in the X-axis direction and the other of the upper portion and the lower portion is fixed in the Y-axis direction.

[0084] In addition, for example, in the above-described embodiments, the in-box fixation members 20 abut against the side surfaces of the protruding portions 101. However, in a case where the protruding portions 101 are not to be provided, the in-box fixation members 20 may directly abut against the side surfaces of the packaging target 100.

[0085] In addition, for example, use of the in-box fixation members 20 can also be applied to the package 1 having a small width in the X-axis direction as shown in FIGS. 4 and 8.

[0086] In addition, for example, the in-box fixation members 20 may abut against two protruding portions 101 from an inner side, may abut against the two protruding portions 101 from an outer side, or may abut against the two protruding portions 101 from both sides. These configurations can be applied to any of the above-described embodiments, and these configurations can be replaced and combined freely.
