Description

Technical Field

[0001] Embodiments of the present invention relate to packaging materials.

Background Art

[0002] Conventionally, for example, LED lighting fixtures for the purpose of renewing from fluorescent lighting fixtures are known. Such lighting fixtures tend to have a shallow embedding depth in the ceiling surface, and an attachment member protruding from the back of the fixture body is added to enable installation on existing hanging bolts without processing. If the attachment member protrudes from the fixture body in the packaged state, the packaging volume increases, leading to an increase in waste materials and transportation costs. Therefore, in the packaged state, the packaging volume is reduced by storing the attachment member inside the fixture body. For this reason, a packaging material, which is a cushioning material, is wound around the attachment member so as not to damage the fixture body. During construction, after opening the individual packing box, the fixture body is rotated up and down, the packaging material is torn into pieces, the lighting fixture is rotated up and down again, and the remaining packaging material is removed.

[0008] One embodiment will be described below with reference to the drawings.

[0009] Figure 5 shows a perspective view of the packaging material 10. The packaging material 10 is used to package the packaged item 11 shown in Figure 3 and has the function of cushioning material. The packaged item 11 can be any item, but in this embodiment, an example is given of a mounting member for attaching the lighting fixture 12 shown in Figures 1 and 2 to the installation site.

[0010] The illustrated lighting fixture 12 is a recessed lighting fixture that is installed embedded in a recessed opening provided in the ceiling panel, which is the installation area. The lighting fixture 12 is formed in an elongated shape, and the recessed opening in the ceiling panel into which the lighting fixture 12 is installed is also formed in an elongated shape. Above the ceiling panel, there is a ceiling structure of the facility, and the lighting fixture 12 can be attached to a pair of suspension bolts installed on this structure.

[0011] The lighting fixture 12 is a recessed base light that is installed in a long, rectangular shape, with the light-emitting area being a continuous line along its length. The lighting fixture 12 comprises a fixture body 15, a light source unit (light source bar) 16 positioned on the fixture body 15, a terminal block 17 and a power supply unit 18 positioned on the fixture body 15, etc., and is attached to a suspension bolt via a pair of mounting members, which are packaging materials 11. In this embodiment, the front side of the lighting fixture 12 is described as the lower side and the rear side as the upper side, based on the installed state of the lighting fixture 12.

[0012] The fixture body 15 is made of metal (sheet metal) and has an opening on its bottom side. The fixture body 15 has a long reflector 20 and end plates 21 attached to both ends of the reflector 20 in the longitudinal direction. The fixture body 15 is formed to be low in height, so that it is embedded to a shallow depth in the recessed opening of the ceiling panel when installed.

[0013] The reflector 20 has a main body portion 23, both side reflector portions 24 protruding from both sides in the short side direction (width direction) intersecting the longitudinal direction of the main body portion 23, and a decorative frame portion 25 provided on the tip side of these reflector portions 24. The main body portion 23 has a top plate portion 27 and side plate portions 28 bent from both sides in the short side direction of the top plate portion 27, and is formed in a substantially U-shaped cross section opening downward. A pair of reflector openings 29 through which the package 11 is inserted and arranged are provided at both end sides in the longitudinal direction of the top plate portion 27. The reflector openings 29 are smaller than the width in the short side direction of the top plate portion 27 and are formed in a rectangular shape long along the longitudinal direction of the top plate portion 27. A wiring hole 30 for drawing in a power line wired to the ceiling back is provided near the center in the longitudinal direction of the top plate portion 27. Further, the reflector portions 24 are provided so as to expand and incline obliquely downward from both sides in the short side direction of the main body portion 23.

[0014] The end plate 21 closes the longitudinal end face of the reflector 20. The end plate 21 has a decorative frame portion 32 continuous with the decorative frame portion 25 of the reflector 20.

[0015] Furthermore, the appliance main body 15 has a pair of spring receivers 34 for detachably attaching the light source unit 16. The spring receivers 34 are attached on the lower surface side of the top plate portion 27 at positions outside the longitudinal direction of the reflector opening 29.

[0016] Also, the light source unit 16 is long and slenderly formed. The light source unit 16 includes an elongated chassis 36, a light emitting module (not shown) disposed on the lower surface side of the chassis 36, a cover 38 attached to the chassis 36 covering the light emitting module, and a pair of mounting springs 39 for detachably attaching to the appliance main body 15.

[0017] The light-emitting module includes a long substrate and a plurality of light-emitting elements mounted on this substrate. As the light-emitting elements, semiconductor light-emitting elements such as LEDs and organic ELs are used. The plurality of light-emitting elements are mounted in one row or multiple rows along the longitudinal direction of the substrate. A light source-side connection cable with a connector is connected to the light-emitting module, and this light source-side connection cable is drawn out to the back side of the chassis 36.

[0018] The cover 38 includes a long translucent cover 41 and end face covers 42 attached to both ends of this translucent cover 41. The translucent cover 41 is made of, for example, resin and has translucency and light diffusion properties. The lower surface side of the translucent cover 41 is formed with a convexly curved cross-section perpendicular to the longitudinal direction, and the upper surface side is fitted and attached to both sides of the chassis 36 from the longitudinal direction. And the translucent cover 41 becomes a light-emitting region that emits light in a line shape along the longitudinal direction. Also, the end face cover 42 is made of, for example, resin, but may be non-translucent or may have translucency. The end face cover 42 is attached to the end of the translucent cover 41 attached to the chassis 36 and holds the translucent cover 41 on the chassis 36.

[0019] The mounting spring 39 is mounted on both ends in the longitudinal direction on the upper surface side of the chassis 36 in a state where a spring force is applied downward. And the mounting spring 39 is hooked on the spring receiver 34 of the appliance main body 15, and is configured to pull up the light source unit 16 to the appliance main body 15 by the spring force of the mounting spring 39 and attach the light source unit 16 to the appliance main body 15. Also, the light source unit 16 can be pulled down against the spring force of the mounting spring 39, and the light source unit 16 can be removed from the appliance main body 15 by removing the mounting spring 39 from the spring receiver 34.

[0020] The terminal block 17 is attached near the center in the longitudinal direction on the lower surface side of the top plate portion 27 of the appliance main body 15, and a power line drawn from the wiring hole 30 of the top plate portion 27 is connected. The terminal block 17 is electrically connected to the power supply unit 18 by internal wiring.

[0021] Furthermore, the power supply unit 18 converts the external power supplied through the terminal block 17 into a predetermined lighting power supply for illuminating the light-emitting elements of the light-emitting module of the light-emitting module of the light-emitting unit 16, and supplies it to the light-emitting module. The primary side of the power supply unit 18, which is the external power input side, is electrically connected to the terminal block 17 by internal wiring. A power supply connection cable 43 with a connector (shown in Figure 8, etc.) is connected to the secondary side of the power supply unit 18, which is the lighting power output side, and this power supply connection cable 43 is detachably connected to the light-emitting side connection cable of the light-emitting unit 16 by a connector connection. The power supply unit 18 is mounted near the center in the longitudinal direction on the underside of the top plate portion 27, with the primary side facing the wiring hole 30 and the terminal block 17.

[0022] Furthermore, the packaging 11 attached to the reflector 20 of the main body 15 of the device is separate from the reflector 20, is inserted through the reflector opening 29 from below, and protrudes upward from the top plate portion 27 on the upper side of the reflector 20.

[0023] The packaging 11 is designed to allow a lighting fixture 12, which has a shallow embedding depth in the ceiling panel, to be installed on existing suspension bolts without any modifications. The packaging 11 is integrally formed, for example, by press-forming a metal plate. As shown in Figure 3, the packaging 11 has an opening 45. The packaging 11 of this embodiment has a surface portion 46 with the opening 45, and side portions 47 connected to both sides of the surface portion 46, with the side opposite the opening 45 being open. That is, the packaging 11 has a shape in which opposite sides are open. The packaging 11 is used with the surface portion 46 facing upwards. The packaging 11 can be positioned in a storage position where it is stored in the reflector 20 (main body portion 23) (see Figure 4(a), etc.), and can also be moved from this storage position to a protruding position where it protrudes above the reflector 20 (see Figure 4(b)).

[0024] The surface portion 46 is formed in a longitudinal shape. An elongated hole or groove-shaped opening 45 is formed along the longitudinal direction of the surface portion 46. In this embodiment, the opening 45 is a suspension bolt mounting portion to which a suspension bolt can be attached with a washer and nut. In addition, both sides of the longitudinal central portion of the opening 45 are notches 48 that are cut out so as to extend from the surface portion 46 to the side portion 47, and the surface portion 46 is divided in the longitudinal direction by these notches 48. At the edge of the notches 48, a fall prevention portion 49 is formed protruding downward from the surface portion 46 to prevent the washer and nut from falling out.

[0025] At both longitudinal edges of the side portion 47, abutment portions 51 are provided at the top. Furthermore, at one longitudinal edge of the side portion 47, a storage locking portion 52 and a guide portion 53 are provided in order below the abutment portion 51. At the other longitudinal edge of the side portion 47, a storage restricting portion 54 and a relief portion 55 are provided in order below the abutment portion 51. Finally, at the lower end of the side portion 47, an engagement portion 56 is provided along the longitudinal direction, extending across both edges.

[0026] The contact portion 51 has a width between the contact portions 51 at both ends that is wider than the longitudinal opening width of the reflector opening 29, allowing it to contact the top plate portion 27 of the reflector 20 when the packaged item 11 is in the storage position.

[0027] The storage locking portion 52 protrudes, for example, in a triangular shape, and the width between the tip of the storage locking portion 52 and the storage restricting portion 54 is slightly wider than the longitudinal opening width of the reflector opening 29. This allows it to lock onto the lower edge of the top plate portion 27 of the reflector 20, and it can also overcome the edge of the top plate portion 27 by being pressed in the direction of protrusion from the reflector 20. When the storage locking portion 52 engages with the lower side of the edge of the top plate portion 27, the packaged item 11 is locked in a temporarily secured storage position.

[0028] The guide portion 53 is inclined downward from the storage locking portion 52 to one side in the longitudinal direction, and the width between the guide portion 53 and the relief portion 55 at the lower end is set to be approximately the same as the longitudinal opening width of the reflector opening 29. Therefore, the packaged item 11 can be inserted into the reflector opening 29 from below with the upper part above the engaging portion 56 and can protrude above the top plate portion 27 of the reflector 20.

[0029] The engaging portion 56 engages with the inner surface of the reflector 20 at a protruding position where the packaged item 11 protrudes upward from the reflector 20, and supports the main body of the device 15.

[0030] Furthermore, the side portion 47 is provided with a locking piece 57 that secures the packaged item 11 to the reflector 20 in a protruding position. The locking piece 57 is cut and bent outwards on the outer surface side of the side portion 47 with its upper side as a pivot point. The locking pieces 57 are arranged, for example, at two locations in the longitudinal direction of each side portion 47. When the packaged item 11 is moved from the storage position to the upper protruding position, the locking piece 57 contacts the edge of the reflector opening 29 and elastically deforms, passing over the edge of the reflector opening 29, and by elastic force protrudes into the upper surface area of ​​the top plate portion 27 of the reflector 20, securing the packaged item 11 in the protruding position.

[0031] Furthermore, the side portion 47 is provided with a width restricting portion 58 that prevents the width between the two side portions 47 from becoming narrower than a predetermined width. The width restricting portion 58 is bent from the lower edge of the notch portion 48 of the side portion 47 toward the inner surface of the side portion 47. The width restricting portions 58 of the two side portions 47 are abutted against each other.

[0032] Then, in the packaged state of the lighting fixture 12, as shown in Figures 8(b) and 9, the packaged item 11 is attached to the reflector opening 29 of the reflector 20 (fixture body 15) while being packaged with the packaging material 10.

[0033] The packaging material 10 shown in Figures 5 to 7 is designed to prevent the packaged item 11 from damaging the device body 15 due to vibrations during attachment to the device body 15 or during transportation. The packaging material 10 is integrally formed from paper, such as corrugated cardboard. The packaging material 10 has a first packaging section 60, a side packaging section 61, and a second packaging section 62. The packaging material 10 is rectangular in shape, with sides along a longitudinal direction which is a first direction and a short direction which is a second direction that intersects or is perpendicular to the first direction. The second packaging section 62, the side packaging section 61, the first packaging section 60, the side packaging section 61, and the second packaging section 62 are arranged in that order from one end to the other in the longitudinal direction. In the illustrated example, the side packaging sections 61 and the second packaging sections 62 are identical or substantially identical in shape, and the packaging material 10 is symmetrical or substantially symmetrical in the longitudinal and transverse directions. However, the design is not limited to this, and the shapes of the side packaging sections 61 or the second packaging sections 62 may differ from each other depending on the shape of the packaged item 11.

[0034] The first packaging section 60 is a mounting surface on which the lower side of the packaged item 11, opposite to the opening 45 (surface section 46), is placed. The first packaging section 60 is formed longitudinally in the short direction of the packaging material 10. In this embodiment, the first packaging section 60 is formed in a rectangular shape. The first packaging section 60 has a width greater than the width of the packaged item 11 and a length shorter than the length of the packaged item 11, for example, the length of the engaging section 56.

[0035] A cut-off portion 64 is formed in the first packaging portion 60. The cut-off portion 64 is provided in the first packaging portion 60 so as to be cut along the short direction of the packaging material 10, that is, along the longitudinal direction of the first packaging portion 60. By cutting the cut-off portion 64, the packaging material 10 is divided longitudinally at the position of the first packaging portion 60. The cut-off portion 64 may have any shape as long as it can be easily cut off, but in this embodiment it has a strip portion 66 and wide portions 67 provided at least at one end of the strip portion 66, and at both ends in the illustrated example.

[0036] The strip portion 66 is provided along the short side of the packaging material 10 with a predetermined width in the longitudinal direction of the packaging material 10. In this embodiment, the strip portion 66 has a constant or substantially constant width, and the end portion connected to the wide portion 67 is inclined to widen toward the width of the wide portion 67. The outer edge of the strip portion 66 is processed, for example, in a perforated manner so that it can be easily cut off.

[0037] The wide portion 67 is provided at both ends of the strip portion 66 in the short direction of the packaging material 10, and is tab-shaped and wider in the longitudinal direction of the packaging material 10 than the strip portion 66. The wide portion 67 is a gripping portion that is grasped when cutting off the cut portion 64. Both sides of the wide portion 67 are cut into the first packaging portion 60. The wide portion 67 is also bendable in the thickness direction of the first packaging portion 60 from the connecting portion 68 that is connected to the strip portion 66. The connecting portion 68 only needs to be able to easily bend the wide portion 67 relative to the first packaging portion 60, and may have fold lines or be processed in a perforated manner.

[0038] Furthermore, side packaging sections 61 are connected to both sides of the first packaging section 60 via folding sections 70. The folding sections 70 only need to be able to easily fold the side packaging sections 61 relative to the first packaging section 60, and may have fold lines or be processed in a perforated manner.

[0039] The side packaging sections 61 are positioned on both sides of the packaged item 11 and are opposing sections facing the side sections 47, formed by folding from the first packaging section 60 via the folding section 70. The side packaging sections 61 are formed longitudinally in the short direction of the packaging material 10. In this embodiment, each side packaging section 61 is formed in a rectangular shape. The side packaging sections 61 have a width greater than the height of the packaged item 11 and a length shorter than the length of the packaged item 11, and are the same length as or approximately the same length as the first packaging section 60. In the illustrated example, the width of the side packaging section 61 is equal to or approximately the same as the width of the first packaging section 60, but is not limited to this and can be set according to the size and shape of the packaged item 11.

[0040] The second packaging section 62 is connected to the end side of the side packaging section 61, that is, on the side opposite to the first packaging section 60 in the short direction of the side packaging section 61, via a folding section 71. The folding section 71, like the folding section 70, only needs to be able to easily fold the second packaging section 62 relative to the side packaging section 61, and may have creases or be processed in a perforated manner.

[0041] The second packaging section 62 is a portion of the packaged item 11 that is positioned on the face portion 46 side by being folded from the side packaging section 61 via the folding section 71. The second packaging section 62 is formed longitudinally in the short direction of the packaging material 10. In this embodiment, each second packaging section 62 is formed in a rectangular shape. The second packaging section 62 has a width of about half the width of the face portion 46 of the packaged item 11 and a length shorter than the length of the packaged item 11, and is the same or approximately the same length as the first packaging section 60 and the side packaging section 61. In the illustrated example, the width of the second packaging section 62 is about half the width of the first packaging section 60 and the side packaging section 61, but it is not limited to this and can be set according to the size and shape of the packaging section 11.

[0042] The second packaging section 62 has a tip end, that is, the end opposite to the side packaging section 61, that can be inserted into the opening 45 of the packaged item 11. For example, the second packaging section 62 has a bent portion 72 that extends in the short direction of the packaging material 10. The bent portion 72 divides the second packaging section 62 into a base end covering portion 73 and a tip end insertion portion 74. The covering portion 73 is the part that covers the surface portion 46 of the packaged item 11, and the insertion portion 74 is the part that is inserted into the opening 45 of the packaged item 11. In this embodiment, the position of the bent portion 72 is set near the center of the width of the second packaging section 62, but it is not limited to this and may be set according to the width of the surface portion 46 and the size of the opening 45. The bent portion 72 only needs to be able to easily bend the insertion portion 74 relative to the covering portion 73, and may have creases or be processed in a perforated manner. In the illustrated example, the length of the cover portion 73 and the insertion portion 74 are set to be the same or approximately the same in the short-side direction of the packaging material 10. However, the design is not limited to this, and for example, the length of the end of the insertion portion 74 may be made shorter than the length of the cover portion 73 to make it easier to insert into the opening 45.

[0043] Next, the method of packaging the packaged items 11 using the packaging material 10 will be explained.

[0044] As shown in Figure 6(b), the packaged item 11 is placed on the packaging material 10 shown in Figure 6(a). At this time, the packaged item 11 is placed with the opening 45 side, i.e., the surface portion 46 side, facing upwards, and the engaging portion 56 side, which is opposite to the opening 45, is placed on the first packaging portion 60. In this state, both ends of the engaging portion 56 protrude from the first packaging portion 60 in the short-side direction of the packaging material 10.

[0045] Next, as shown in Figure 6(c), one side packaging portion 61 of the packaging material 10 is folded in a valley fold shape from the folding portion 70 relative to the first packaging portion 60 so that it faces the side portion 47 of the packaged item 11. Also, as shown in Figure 6(d), the second packaging portion 62 is folded in a valley fold shape from the folding portion 71 relative to the side packaging portion 61 facing the side portion 47 of the packaged item 11 so that it faces the surface portion 46 of the packaged item 11. Furthermore, as shown in Figure 6(e), the second packaging portion 62 is folded from the folding portion 72 so that the insertion portion 74 is inserted into the opening 45 of the packaged item 11 from above.

[0046] In the same manner as in Figures 6(c) to 6(e), as shown in Figures 6(f) and 6(g), the other side packaging portion 61 of the packaging material 10 is folded in a valley fold from the folding portion 70 relative to the first packaging portion 60 so that it faces the side portion 47 of the packaged item 11. The second packaging portion 62 is then folded in a valley fold from the folding portion 71 relative to the side packaging portion 61 facing the side portion 47 of the packaged item 11 so that it faces the surface portion 46 of the packaged item 11. The second packaging portion 62 is also folded from the folding portion 72 so that the insertion portion 74 is inserted into the opening 45 of the packaged item 11 from above.

[0047] In this state, as shown in Figure 7, the tips of the insertion parts 74 on both sides, which are inserted into the opening 45, abut against each other, causing the insertion parts 74 to act as a reaction force that separates them from each other, thereby maintaining the state in which the insertion parts 74 are inserted into the opening 45.

[0048] After this, the packaged item 11, which has been wrapped in the packing material 10, is turned upside down as shown in Figure 6(h) so that the first packing section 60 is on top, and as shown in Figure 8(a), it is attached to the top plate section 27 between the side plate sections 28, 28 of the reflector 20, with its longitudinal direction aligned with the inverted fixture body 15. At this time, the packaged item 11 is inserted diagonally into the reflector opening 29 together with the packing material 10, and the area near the guide section 53 is brought into contact with the edge of the reflector opening 29, and it is rotated to push into the reflector opening 29 from that position.

[0049] In the lighting fixture 12 configured in this way, as shown in Figure 9, the packaging 11, which is the mounting component, is positioned in a storage location within the reflector 20 when it is shipped from the factory. In the storage location, the packaging 11 has its contact portion 51 in contact with the upper surface of the top plate portion 27, and its storage locking portion 52 is engaged with the lower edge of the top plate portion 27, temporarily securing it to the reflector 20. The packaging 11 in the storage location has a low protrusion height above the reflector 20. Therefore, the packaging size, i.e., the packaging volume, of the lighting fixture 12 in its packaged state can be reduced, which is a favorable form for distribution and reduces waste and transportation costs.

[0050] Furthermore, as shown in Figure 6(i), the packaging material 10 is angled vertically by bending the wide portion 67 from the connecting portion 68 toward the first packaging portion 60, as shown in Figure 8(b). This allows the power supply side connection cable 43, which is connected via a connector from the power supply unit 18 to the light source unit 16 (shown in Figure 1, etc.), to be placed on the first packaging portion 60 of the packaging material 10 and routed along the wide portions 67, 67, thereby holding and fixing it in a position that goes over the packaged item 11.

[0051] Next, the installation method and operation of the lighting fixture 12 will be explained.

[0052] When installing the lighting fixture 12, after unpacking the individual box, the first step is to remove the packaging material 10 from the packaged items 11. That is, as shown in Figure 10(a), the cut-off portion 64 is cut from the first packaging portion 60 by grasping one wide portion 67 and pulling it upward toward the other wide portion 67. As a result of this cutting, as shown in Figure 10(b), the packaging material 10 is divided into two pieces of packaging material 76 in the width direction. By slightly lifting the fixture body 15 and pulling these pieces of packaging material 76 upward, the packaging material 10 can be removed from the packaged items 11 without turning the fixture body 15 upside down.

[0053] Subsequently, the packaged item 11 is moved from its storage position relative to the reflector 20 to an upward protruding position. That is, by pressing the packaged item 11 in the direction of protrusion from the reflector 20, the storage locking portion 52 is made to move over the edge of the top plate portion 27, and as shown in Figure 4(b), the packaged item 11 is moved to a protruding position that protrudes above the reflector 20. At this time, the guide portion 53 of the packaged item 11 contacts the longitudinal edge of the reflector opening 29, guiding the movement of the packaged item 11 from the storage position to the protruding position, and positioning the packaged item 11 relative to the longitudinal direction of the reflector 20 at the protruding position of the packaged item 11. Furthermore, at the protruding position of the packaged item 11, the engaging portions 56 on both sides of the packaged item 11 engage with the inner surface of the reflector 20, positioning the packaged item 11 relative to the short direction of the reflector 20. Furthermore, when the package 11 moves from its storage position to an upward protruding position, the locking piece 57 of the package 11 comes into contact with the edge of the reflector opening 29 and undergoes elastic deformation. By passing over the edge of the reflector opening 29, it protrudes into the upper surface area of ​​the top plate portion 27 of the reflector 20 by elastic force, locking the package 11 in the protruding position.

[0054] The power wires, which are routed in the ceiling cavity, are pulled out through a recessed opening in the ceiling panel and also routed into the inside of the fixture body 15 through the wiring hole 30 of the fixture body 15. The pulled-in power wires may be connected to the terminal block 17 at this point, or they may be connected after the fixture body 15 is installed on the ceiling side.

[0055] The upper part of the fixture body 15 is inserted from below into the recessed opening in the ceiling panel, the suspension bolt is inserted through the opening 45 of the packaged item 11, and a nut is screwed onto the tip of the suspension bolt via a washer and tightened, causing the fixture body 15 to rise together with the packaged item 11, and the decorative frame parts 25 and 32 around the fixture body 15 come into contact with the lower surface of the ceiling panel, thereby installing the fixture body 15 on the ceiling side.

[0056] Next, the light source side connection cable of the light source unit 16 is connected to the power supply side connection cable 43 of the power supply unit 18 of the fixture body 15 using a connector, and the mounting spring 39 of the light source unit 16 is hooked onto the spring receiving bracket 34 of the fixture body 15, and the spring force of the mounting spring 39 pulls the light source unit 16 up onto the fixture body 15, thereby attaching the light source unit 16 to the fixture body 15. The light source unit 16 attached to the fixture body 15 conceals the internal structure of the main body 23, including the reflector opening 29 of the reflector 20.

[0057] Then, when an external power supply is supplied to the installed lighting fixture 12, the lighting power converted by the power supply unit 18 is supplied to the light-emitting module of the light source unit 16, the light-emitting element of the light-emitting module lights up, and the light from the light-emitting element passes through the cover 38 and illuminates the lighting space below.

[0058] As described above, according to one embodiment of the packaging material 10, the side of the packaged item 11 opposite to the opening 45 is placed in the first packaging section 60, the side packaging sections 61 connected to both sides of the first packaging section 60 are bent from the first packaging section 60 and placed on both sides of the packaged item 11, and the second packaging section 62 connected to the end sides of the side packaging sections 61 is bent from the side packaging sections 61 placed on both sides of the packaged item 11 and the tip is inserted into the opening 45, thereby allowing the packaging material 10 to be easily fixed to the packaged item 11 while the packaged item 11 is in place. Furthermore, by providing a cut-off section 64 in the first packaging section 60 so that it can be cut off, the cut-off section 64 can be cut off and the packaging material pieces 76 of the packaging material 10, which have been divided on both sides, can be pulled out, allowing the packaging material 10 to be easily removed from the packaged item 11.

[0059] Therefore, it is possible to provide a packaging material 10 that can be easily used to package the packaged goods 11 and can also be easily removed from the packaged goods 11.

[0060] Furthermore, since the opposite side of the opening 45 of the packaged item 11 is also open, it is difficult for the packaging material piece 76 to be pressed down over a wide area by the weight of the packaged item 11 when the cut-off portion 64 is removed, making it easier to remove the packaging material piece 76.

[0061] Furthermore, since the packaging material 10 has a simple shape that is symmetrical or nearly symmetrical in both the longitudinal and width directions, it is easy to manufacture, and it is less likely to be misaligned with the orientation of the packaged items 11 during packaging, resulting in good packaging workability.

[0062] In particular, if the packaged item 11 is a mounting component for attaching the lighting fixture 12 to the ceiling, the packaging material 10 can be easily removed without having to turn the bulky fixture body 15 upside down. This eliminates the need to turn the fixture body 15 upside down, tear the packaging material, turn the fixture body 15 upside down again, and remove the remaining packaging material, thus improving work efficiency during installation.

[0063] Furthermore, the opening 45 for fixing the suspension bolt can be used as an opening for inserting and fixing the tip side of the second packaging section 62 of the packaging material 10.

[0064] Furthermore, the cut-off portion 64 is provided with a wide portion 67 at at least one end of a band portion 66 that is provided along the short side of the first packaging portion 60 with a predetermined width in the longitudinal direction. By pinching and pulling up the wide portion 67, stress can be applied to the band portion 66, making it easy to cut off the cut-off portion 64. In addition, the wide portion 67 can be bent from the first packaging portion 60 to hold wiring such as the power supply connection cable 43 when the packaged item 11 is packaged and attached to the main body of the device 15.

[0065] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of Symbols]
