[0013] The following describes a packaging material according to one embodiment of the present invention, with reference to the drawings.

[0014] The overall structure of the packaging material 1 will be described with reference to Figures 1 and 2. Figure 1 is a cross-sectional perspective view of the packaging material 1, and Figure 2 is a cross-sectional side view of the packaging material 1 (with the packaged item 10 contained inside). In this embodiment, the packaging material 1 that contains a fuser unit 3 used in printers and the like will be described as the packaged item. The fuser unit 3 has a main body 5 that heats the toner image by IH and a plurality of power cords 7. The main body 5 has a rectangular parallelepiped shape. The power cords 7 are integrally connected to one short side of the main body 5 via a mounting part 9.

[0015] Packaging material 1 comprises a box body 11, cushioning material 13 placed inside the box body 11, and spacers 15.

[0016] First, let's describe the box body 11. The box body 11 has a rectangular bottom plate 21, a pair of long side plates 23 and a pair of short side plates 25 rising from the four sides of the bottom plate 21, and a lid 27. The length of the bottom plate 21 in the longitudinal direction X is longer than the length of the main body 5 of the fixing unit 3 in the longitudinal direction X, and the length in the short direction Y is equal to the length of the main body 5 in the short direction Y. The height of the side plates 23 and 25 is slightly higher than the combined height of the main body 5 of the fixing unit 3 and the bundle of multiple power cords 7. The box body 11 is made of, for example, cardboard.

[0017] Next, the cushioning material 13 will be described with reference to FIG. 3 as well. FIG. 3 is a perspective view showing the cushioning material 13. The cushioning material 13 is created by assembling a cardboard blank sheet as will be described later. The cushioning material 13 has a rectangular bottom plate 31 with a planar shape equivalent to that of the bottom plate 21 of the box body 11, and a pair of square tubular side walls 33 erected along both long sides of the bottom plate 31. A rectangular parallelepiped-shaped accommodation space 35 with an open top surface is formed between the two side walls 33. The height of the two side walls 33 (the height of the accommodation space 35) is approximately equivalent to the height of the bundle of power cords 7.

[0018] Both side walls 33 have a pressing piece 37 protruding into the accommodation space 35 substantially at the center in the longitudinal direction X.

[0019] Next, the spacer 15 will be described with reference to FIG. 4 as well. FIG. 4 is a perspective view showing the spacer 15. The spacer 15 is also created by assembling a cardboard blank sheet as will be described later. The spacer 15 has a substantially H-shaped planar shape and a predetermined height. Specifically, the spacer 15 has a flat rectangular parallelepiped shape, and substantially rectangular first cutouts 41 and second cutouts 43 are formed on one side surface and the other side surface.

[0020] Next, the procedure for accommodating the fixing unit 3 in the packaging material 1 described above will be described again with reference to FIGS. 1 and 2. First, the cushioning material 13 is placed on the bottom plate 21 of the box body 11 of the packaging material 1. Then, the power cord 7 of the fixing unit 3 is curved downward with respect to the main body 5, and the power cord 7 is accommodated in the accommodation space 35 of the cushioning material 13, and at the same time, the main body 5 is placed on the upper surfaces of the two side walls 33 of the cushioning material 13. When the power cord 7 is accommodated in the accommodation space 35 of the cushioning material 13, the power cord 7 is pressed from above by the two pressing pieces 37.

[0021] In the state where the power cord 7 is housed in the housing space 35 and the main body 5 is placed on the upper surfaces of the both side walls 33 as described above, a gap is formed between one short side surface of the main body 5 and the inner surface of the short side plate 25 of the box body 11 facing this short side surface. Therefore, the spacer 15 is arranged in this gap. The attachment portion 9 of the main body 5 is housed in the first notch 41 of the spacer 15, and the bent portion of the power cord 7 is housed in the second notch 43. Actually, after bending the power cord 7 of the fixing unit 3 downward with respect to the main body 5, the attachment portion 9 is housed in the first notch 41 of the spacer 15, and the bent portion of the power cord 7 is housed in the second notch 43. Then, the power cord 7 is housed in the housing space 35, and the main body 5 is placed on the upper surfaces of the both side walls 33.

[0022] After that, if necessary, a cushioning material (not shown) is arranged above the main body 5, and the lid body 27 is closed.

[0023] Next, referring to FIG. 5, the blank sheet 50 of the cushioning material 13 will be described. FIG. 5 is an exploded view of the cushioning material 13. The cushioning material 13 is created by bending the blank sheet 50. FIG. 5 shows the inner surface of the blank sheet 50 which becomes the inner surface of the cushioning material 13. The blank sheet 50 is made of, for example, cardboard.

[0024] The blank sheet 50 has a rectangular planar shape, and has a bottom plate portion 51 forming the bottom plate 21 of the cushioning material 13, and side wall portions 53 connected to both long sides of the bottom plate portion 51 and forming the side walls 33 of the cushioning material 13.

[0025] First, let's describe the base plate portion 51. In the center of the base plate portion 51 along the longitudinal direction X, there is a rectangular central opening 61. Two insertion pieces 63 are formed on each side of the central opening 61 along the longitudinal direction X. The two insertion pieces 63 are spaced apart along the longitudinal direction X. One insertion piece 63 is formed by creating a cut line 65 in the base plate portion 51 along an inverted trapezoid shape from one of the long sides of the base plate portion 51, and the other insertion piece 63 is formed by creating a cut line 65 in the base plate portion 51 along an inverted trapezoid shape from the other long side of the base plate portion 51. An inverted trapezoid is a trapezoid in which the bottom side (the side on the long side of the base plate portion 51) is shorter than the top side. In this example, the two cut lines 65 are connected to form a rectangular window portion 67 around the two insertion pieces 63.

[0026] Next, each side wall portion 53 will be described. Each side wall portion 53 consists of first to fifth side portions 71, 72, 73, 74, and 75, in order from the side of the base plate portion 51. The length in the longitudinal direction X of the first to fifth side portions 71, 72, 73, 74, and 75 is the same as the length in the longitudinal direction X of the base plate portion 51, and the length in the short direction Y is equal. The first side portion 71 and the second side portion 72, the second side portion 72 and the third side portion 73, the third side portion 73 and the fourth side portion 74, and the fourth side portion 74 and the fifth side portion 75 are connected via first to fourth valley fold lines 81, 82, 83, and 84, respectively.

[0027] Two rectangular slots 91 are formed in the fourth side portion 74. The two slots 91 are formed in the same position in the short direction Y as the insertion piece 63 formed along the long side on the side to which the side wall portion 53 is connected. Parts of the slots 91 extend beyond the third valley fold line 83 to reach the third side portion 73.

[0028] Furthermore, a U-shaped cut line 93 is formed in the center of the longitudinal direction X on the fourth side portion 74, extending from the third valley fold line 83. When the third valley fold line 83 is used for the valley fold, the portion enclosed by the cut line 93 is cut out from the fourth side portion 74. The portion enclosed by the cut line 93 becomes the retaining piece 37 of the cushioning material 13.

[0029] Next, we will explain how to create the cushioning material 13 from the blank sheet 50. First, the second to fifth side sections 72, 73, 74, and 75 of each side wall section 53 are folded along the first to fourth valley fold lines 81, 82, 83, and 84, and the outer surface of the fifth side section 75 is overlapped with the inner surface of the first side section 71. This forms a rectangular tube with the overlapped first and fifth side sections 71 and 75, the second side section 72, the third side section 73, and the fourth side section 74. Then, the insertion piece 63 formed on the bottom plate section 51 is inserted into the insertion opening 91 of the fourth side section 74. This fixes the first to fifth side sections 71, 72, 73, 74, and 75 to the rectangular tube. This rectangular tube becomes the side walls 33 of the cushioning material 13. Furthermore, the space enclosed by the side wall sections 53 and the bottom plate section 51, which are assembled into a rectangular tube, becomes the storage space 35 for the cushioning material 13.

[0030] Furthermore, the retaining piece 37 of the fourth side portion 74 rises up from the fourth side portion 74 and protrudes into the storage space 35 at the same height as the third side portion 73, thus forming the retaining piece 37.

[0031] Next, the blank sheet 100 of the spacer 15 will be described with reference to Figure 6. Figure 5 is an unfolded view of the spacer 15. Figure 6 shows the inner surface of the blank sheet 100, which will be the upper surface of the spacer 15. The blank sheet 100 is made of, for example, corrugated cardboard.

[0032] The blank sheet 100 consists of first to fifth base sections 101, 102, 103, 104, and 105 connected in a row. The first to fifth base sections 101, 102, 103, 104, and 105 are connected via a first mountain fold line 111, a first valley fold line 112, a second mountain fold line 113, and a third valley fold line 114. Each base section has a roughly H-shape, the same as the planar shape of the spacer 15, with a first notch 121 formed on one side edge and a second notch 123 formed on the other side edge. The second notch 123 of the first base portion 101 is in communication with the second notch 123 of the second base portion 102, the first notch 121 of the second base portion 102 is in communication with the first notch 121 of the third base portion 103, the second notch 123 of the third base portion 103 is in communication with the second notch 123 of the fourth base portion 104, and the first notch 121 of the fourth base portion 104 is in communication with the first notch 121 of the fifth base portion 105.

[0033] Next, we will explain how to create the spacer 15 from the blank sheet 100. First, the first to fifth base sections 101, 102, 103, 104, and 105 are folded along the first mountain fold line 111, the first valley fold line 112, the second mountain fold line 113, and the third valley fold line 114. In other words, the first to fifth base sections 101, 102, 103, 104, and 105 are folded in an accordion shape. As a result, the first to fourth base sections 101, 102, 103, 104, and 105 overlap in the vertical direction, and the first notch 121 and the second notch 123 of each base section also overlap in the vertical direction. After that, the overlapped first to fifth base sections 101, 102, 103, 104, and 105 are fixed in place with tape or adhesive.

[0034] As is clear from the above description, the packaging material 1 of this embodiment can reliably and compactly accommodate the packaged object (fixing unit 3) having a main body 5 and a power cord 7 directly connected to one side of the main body 5. Specifically, the main body 5 can be placed on the cushioning material 13 to mitigate the impact of a fall. In addition, the power cord 7 can be compactly accommodated in the storage space 35 without being forcibly bent. Furthermore, since the main body 5 is placed on the cushioning material 13, no load is applied to the power cord 7 from the main body when it is dropped, thus protecting the power cord 7 when it is dropped.

[0035] Furthermore, a spacer 15 is interposed between one short side of the main unit 5 (the side to which the power cord 7 is connected) and the inner surface of the side panel 25 of the box 11 of the packaging material 1. Therefore, when the packaging material 1 falls from this short side, no load is applied to the power cord 7 from the main unit 5, thus ensuring the power cord 7 is protected.

[0036] Furthermore, the cushioning material 13 has a retaining piece 37 formed therein to prevent the power cord 7, which is housed in the storage space 35, from coming loose. This allows the power cord 7 to remain housed in the storage space 35, making it easier to house the main unit 5. Therefore, the process of housing the fixing unit 3 into the packaging material 1 can be made more efficient.

[0037] The shape and dimensions of the side walls 33 of the cushioning material 13 can be changed according to the shape and weight of the packaged item. For example, if the packaged item is heavy, the side walls 53 of the blank sheet 50 may be doubled to improve strength. The height of the spacers 15 can also be changed at any time. For example, the height of the spacers 15 can be changed depending on the number of base sections of the blank sheet 100.

[0038] In the above embodiment, an example was described in which the cushioning material 13 and spacer 15 are made by folding blank sheets 50 and 100, respectively. However, the side walls 33 of the cushioning material 13 and the spacer 15 can also be made from foamed resin. However, making them by folding a corrugated cardboard blank sheet as in this embodiment has the advantage of making the dismantling of the packaging material 1 easier and allowing for reuse. In particular, the cushioning material 13 can be assembled without using adhesives or tape.

[0039] Furthermore, the above-described embodiments of the present invention describe preferred embodiments of the packaging box according to the present invention, and therefore may include various technically preferred limitations. However, the technical scope of the present invention is not limited to these embodiments unless otherwise specified. [Explanation of Symbols]
