[0009] Hereinafter, an example of an embodiment of a lighting device according to the present disclosure will be described in detail with reference to the drawings. Note that the scope of the present disclosure includes configurations that are formed by selectively combining the components of the multiple embodiments and variations described below.

[0010] A light bulb set 1 including a light bulb packaging box 2 will be described with reference to Figure 1. Figure 1 is a perspective view showing the overall configuration of the light bulb set 1, with the top surface 30 of the light bulb packaging box 2 open.

[0011] As shown in FIG. 1, the light bulb set 1 consists only of the light bulb 100 and the light bulb packaging box 2 that contains the light bulb 100. In other words, the light bulb set 1 does not include a paper instruction manual with printed instructions on how to use the light bulb 100 or a paper warranty. As will be described in detail later, the contents of the instruction manual and warranty are printed on the inside or outside of at least one selected from the group consisting of the cylindrical portion 10, bottom portion 20, and top portion 30 of the light bulb packaging box 2. This allows the user (consumer) to receive the information without using a paper instruction manual or warranty, thereby reducing the amount of paper used for the instruction manual and warranty. Note that in this specification, the light bulb set 1 refers to the light bulb 100 and the components sold in combination with the light bulb 100.

[0012] The light bulb packaging box 2 has a rectangular prism shape consisting of a cylindrical portion 10 made up of four side panels 11, 12, 13, and 14, a bottom portion 20, and a top portion 30. The light bulb packaging box 2 is made of packaging material such as paperboard or corrugated cardboard. A user can remove the light bulb 100 from inside the light bulb packaging box 2 by opening the top portion 30 of the light bulb packaging box 2.

[0013] The outer shell of the light bulb 100 is formed by a spherical cover 101, a base 102 (see FIG. 5) that connects to a socket, and a housing 103 (see FIG. 5) that connects the cover 101 and the base 102. An LED element (not shown) or the like that serves as a light source is disposed inside the cover 101. Note that the configuration of the light bulb 100 is not limited to this.

[0014] The light bulb 100 is housed inside the light bulb packaging box 2 with the base 102 facing the bottom surface 20 (downward). In other words, when the top surface 30 is opened, the cover 101 is exposed. Furthermore, as will be described in detail later, a partition 50 is provided inside the light bulb packaging box 2, and the light bulb 100 is housed inside the light bulb packaging box 2 at an angle to the central axis (vertical direction) of the light bulb packaging box 2 due to the partition 50. This allows the height of the light bulb packaging box 2 to be reduced, and the light bulb packaging box 2 to be made more compact. As a result, the amount of paper used in the light bulb packaging box 2 can be reduced.

[0015] Next, the light bulb packaging box 2 will be described with further reference to Figure 2. Figure 2 is a development view of the light bulb packaging box 2.

[0016] 2, the light bulb packaging box 2 has a generally square prism shape including a cylindrical portion 10 consisting of four side plates 11, 12, 13, and 14, a bottom surface portion 20 provided at one end of the cylindrical portion 10, and a top surface portion 30 provided at the other end of the cylindrical portion 10. In this embodiment, the bottom surface portion 20 includes three bottom plates 21, 22, and 23, and the top surface portion 30 includes three top plates 31, 32, and 33.

[0017] The four side panels 11, 12, 13, and 14 are connected to one another via fold lines 40. The side panels 11, 12, 13, and 14 have the same height. The height of the side panels 11, 12, 13, and 14 can be set appropriately depending on the size of the light bulb 100 to be housed in the light bulb packaging box 2, but it is preferable that the height be smaller than the height from the top to the bottom of the light bulb 100 when it is upright. In other words, because the light bulb packaging box 2 houses the light bulb 100 in a state where it is tilted diagonally with respect to the central axis of the light bulb packaging box 2, the height of the side panels 11, 12, 13, and 14 can be smaller than the height from the top to the bottom of the light bulb 100 when it is upright. In addition, an adhesive portion 15 for adhering to the side panel 11 is connected to the side of the side panel 14 via the fold line 40.

[0018] Bottom plates 21, 22, and 23 are connected to the lower sides of side plates 11, 12, and 13 via fold lines 41. In this embodiment, bottom plates 21 and 23 have a substantially rectangular shape, and bottom plate 22 has a substantially square shape. In addition, a partition section 50 (described later) is connected to the lower side of side plate 14 via fold line 42.

[0019] An insertion portion 24 is connected to the bottom plate 22 via a fold 43. The insertion portion 24 extends toward the top surface 30 (upward) of the light bulb packaging box 2 and is inserted into the gap between the bottom plates 21, 23 and the side plate 14 when the light bulb packaging box 2 is assembled. When the bottom plates 21, 23 are folded, the insertion portion 24 is inserted into the gap between the bottom plates 21, 23 and the side plate 14, thereby closing the opening on the bottom surface 20 side of the light bulb packaging box 2. In other words, when the light bulb packaging box 2 is assembled, the bottom plate 22 forms the outer surface of the light bulb packaging box 2. In addition, an extension portion 25, which will be described later, is connected to the bottom plate 23 via a fold 45.

[0020] Top plates 31, 32, and 33 are connected to the upper sides of the side plates 11, 12, and 13, respectively, via folds 44. In this embodiment, the top plates 31, 32, and 33 all have a substantially square shape.

[0021] An insertion portion 34 is connected to the top plate 32 via a fold 46. The insertion portion 34 extends toward the bottom surface 20 of the light bulb packaging box 2 and is inserted into the gap between the top plates 31, 33 and the side plate 14 when the light bulb packaging box 2 is assembled. When the top plates 31, 33 are folded, the insertion portion 34 is inserted into the gap between the top plates 31, 33 and the side plate 14, thereby closing the opening on the top surface 30 side of the light bulb packaging box 2. In other words, when the light bulb packaging box 2 is assembled, the top plate 32 forms the outer surface of the light bulb packaging box 2.

[0022] 1, instructions regarding the light bulb 100 housed in the light bulb packaging box 2 are printed on the inner or outer surface of at least one selected from the group consisting of the cylindrical body 10, the bottom surface 20, and the top surface 30. Examples of the instructions regarding the light bulb 100 include product information, handling instructions, installation instructions, precautions, and warranty details for the light bulb 100.

[0023] In this embodiment, instructions regarding the light bulb 100 are printed on the outer surfaces of the side panels 11, 13, and 14, the inner surface of the side panel 13, and the outer and inner surfaces of the top panels 31, 32, and 33. In particular, instructions regarding precautions for using the light bulb 100 are printed on the outer surface of the top panel 31. The outer surface of the top panel 31 is the first area that a user's eyes will be drawn to when opening the top surface 30 (top panel 32). Therefore, by printing instructions regarding precautions for using the light bulb 100 on the top panel 31, the instructions can be effectively communicated to the user.

[0024] Next, with further reference to Figures 3 to 6, we will explain the partitions 50 and extensions 25 arranged inside the light bulb packaging box 2. Figure 3 is a perspective view of the light bulb packaging box 2 seen from the bottom surface 20 side, Figure 4 is a perspective view showing the state in which the bottom surface 20 of the light bulb packaging box 2 is opened, Figure 5 is a cross-sectional view taken along line AA in Figure 3, and Figure 6 is a cross-sectional view taken along line BB in Figure 3.

[0025] As shown in Figures 2 to 6, the divider 50 is disposed inside the light bulb packaging box 2 and is connected to the side plate 14 via the fold 42. The divider 50 has a first portion 51 that is disposed substantially parallel to the bottom surface 20, and a second portion 52 that is connected to the first portion 51 and is disposed along the inner surface of the side plate 14. The divider 50 is disposed on the lower side of the light bulb packaging box 2 and has the function of holding the light bulb 100 inside the light bulb packaging box 2 in a state where it is inclined at an angle with respect to the central axis of the light bulb packaging box 2.

[0026] The first portion 51 has openings 53 at its corners, through which the base 102 of the light bulb 100 passes. In this embodiment, the opening 53 has a generally square shape in a plan view. The shape and size of the opening 53 are not particularly limited as long as the base 102 can pass through it. The opening area of ​​the opening 53 is, for example, 10% to 50%, or alternatively, 15% to 40%, of the area of ​​the first portion 51. By having the light bulb 100 pass through the opening 53, the light bulb 100 can be held stably inside the light bulb packaging box 2.

[0027] The first portion 51 is in approximate contact with the side plates 11, 12, 13, and 14, except for the area where the opening 53 is formed. This makes it easy to hold the light bulb 100 inside the light bulb packaging box 2 in a state where it is tilted obliquely with respect to the central axis of the light bulb packaging box 2. "Approximately in contact" means that the two portions are in contact with each other or are arranged with a small gap between them.

[0028] 3 to 6, the light bulb 100 is in contact with each of the two adjacent side plates 11, 12 out of the four side plates 11, 12, 13, 14. This prevents the light bulb 100 from shifting inside the light bulb packaging box 2, and allows the light bulb 100 to be held stably.

[0029] 4 and 5, the second portion 52 is connected to the side plate 14 via the fold 42 and to the first portion 51 via the fold 47. When the light bulb packaging box 2 is assembled, the second portion 52 abuts against the inner surface of the side plate 14 and is disposed along the inner surface of the side plate 14. In other words, the second portion 52 extends in the up-down direction.

[0030] By providing the second portion 52 that is arranged along the inner surface of the side plate 14, the strength of the light bulb packaging box 2 can be increased, and when an external impact or the like is applied to the light bulb packaging box 2, the divider portion 50 is prevented from shifting, and the light bulb 100 can be stably held inside the light bulb packaging box 2. In other words, if the second portion 52 is not provided, or if the second portion 52 is not arranged along the inner surface of the side plate 14 but extends in a direction that is inclined relative to the up-down direction, the strength of the light bulb packaging box 2 may not be sufficiently ensured. As a result, when an external impact or the like is applied to the light bulb packaging box 2, the divider portion 50 may shift, and the light bulb 100 may not be stably held inside the light bulb packaging box 2.

[0031] In this embodiment, the second portion 52 has a substantially rectangular shape, and the length of the long side of the second portion 52 is substantially the same as the length of the short side of the side panel 14. The length of the short side of the second portion 52 (the length in the vertical direction) can be set appropriately depending on the shape of the bulb 100, and may be, for example, 5 mm or more and 50 mm or less, or 10 mm or more and 30 mm or less.

[0032] 4 and 6, the partition 50 has a hanging part 54 extending from the first part 51 toward the bottom part 20. The hanging part 54 is connected to the first part 51 via a fold 48.

[0033] The hanging portion 54 extends, for example, along the vertical direction when the light bulb packaging box 2 is assembled. Note that the hanging portion 54 may extend in a direction inclined relative to the vertical direction when the light bulb packaging box 2 is assembled. The inclination angle of the hanging portion 54 relative to the vertical direction is, for example, 30° or less, and may also be 20° or less.

[0034] In the present embodiment, hanging portion 54 has a substantially square shape and has a height that is substantially the same as the length of the short side of second portion 52. In other words, when hanging portion 54 extends in the up-down direction, hanging portion 54 abuts against bottom surface portion 20.

[0035] Providing the hanging parts 54 can further increase the strength of the light bulb packaging box 2. As a result, when an external impact or the like is applied to the light bulb packaging box 2, the dividers 50 are prevented from shifting, and the light bulbs 100 can be stably held inside the light bulb packaging box 2. Furthermore, when the hanging parts 54 are in contact with the light bulbs 100, the light bulbs 100 can be pressed down by the hanging parts 54, and the light bulbs 100 can be stably held inside the light bulb packaging box 2.

[0036] 4 and 6, the packaging box 2 for light bulbs has an extension 25 that extends from the bottom surface 20 (bottom plate 23) toward the first portion 51 (upper side). As described above, the extension 25 is connected to the bottom plate 23 via the fold 45.

[0037] When the packaging box 2 for light bulbs is assembled, the height of the extension portion 25 is configured to be slightly smaller than the height of the hanging portion 54. In other words, the extension portion 25 does not abut against the first portion 51. Note that at least a part of the extension portion 25 may abut against the first portion 51.

[0038] Providing the extensions 25 can further increase the strength of the light bulb packaging box 2. As a result, when an external impact is applied to the light bulb packaging box 2, the partitions 50 are prevented from shifting, and the light bulbs 100 can be stably held inside the light bulb packaging box 2.

[0039] 6, the extension 25 is preferably disposed between the hanging part 54 and the base 102 of the light bulb 100. This makes it easier to hold the light bulb 100 stably inside the light bulb packaging box 2.

[0040] Next, an example of a method for assembling the light bulb packaging box 2 will be described with reference to Fig. 2 and Fig. 7 to Fig. 9. Fig. 7 to Fig. 9 are diagrams showing a method for assembling the light bulb packaging box 2. Note that the method for assembling the light bulb packaging box 2 is not limited to the following method.

[0041] 2, the fold lines 40 are each folded in a mountain shape, and the adhesive portions 15 are attached to the inner surfaces of the side plates 11 to form the cylindrical portion 10. Then, the fold lines 44 are each folded in a mountain shape, and the top surface portion 30 is formed.

[0042] 7, with the top surface 30 facing downwards, the bulb 100 is inserted into the cylindrical body 10 so that the cover 101 of the bulb 100 faces downwards. At this time, the bulb 100 is inserted at an angle to the central axis (vertical direction) of the cylindrical body 10, and the base 102 is positioned so that it abuts against the side plates 11 and 12.

[0043] Next, as shown in Figures 2 and 8, folds 47 and 48 are made valley folds to form first portion 51 and hanging portion 54. Then, folds 42 below side panel 14 are made mountain folds to place first portion 51 and hanging portion 54 inside tubular body 10. At this time, base 102 is made to pass through opening 53 provided in first portion 51. As a result, light bulb 100 is placed inside tubular body 10 by partition 50 at an angle with respect to the central axis (vertical direction) of light bulb packaging box 2.

[0044] 2 and 9, fold line 45 is then mountain-folded to form extension portion 25, and then lower fold line 41 of side plate 13 is mountain-folded to place extension portion 25 inside tubular portion 10. At this time, it is preferable that extension portion 25 is placed between hanging portion 54 and light bulb 100. Then, lower fold lines 41 of side plates 11 and 12 are mountain-folded to form bottom portion 20, thereby assembling light bulb packaging box 2.

[0045] As described above, the packaging box 2 for light bulbs of this embodiment has a divider 50 placed inside the packaging box 2 for light bulbs, and holds the light bulbs 100 at an angle to the central axis of the packaging box 2 for light bulbs. The divider 50 is substantially parallel to the bottom surface 20 and has a first portion 51 with an opening 53 through which the light bulb 100 passes, and a second portion 52 connected to the first portion 51 and placed along the inner surface of the side panel 14. This allows the packaging box 2 for light bulbs to be made smaller while maintaining its strength. As a result, the amount of paper used in the packaging box 2 for light bulbs can be reduced, thereby conserving resources.

[0046] The above embodiment can be modified as appropriate without impairing the purpose of the present disclosure. For example, in the above embodiment, the partition 50 is connected to the side panel 14 of the cylindrical body 10, but the partition 50 may be formed as a separate member from the cylindrical body 10. In other words, the light bulb packaging box 2 may be formed from a box body having the cylindrical body 10, the bottom surface 20, and the top surface 30, and the partition 50 housed inside the box body. Even when the partition 50 is formed as a separate member from the box body, the effects of the present disclosure can be achieved.

[0047] Furthermore, in the above embodiment, the opening 53 is a notch formed in a corner of the first portion 51, but the configuration of the opening 53 is not limited to this. For example, the opening 53 may be a through hole formed inside the outer edge of the first portion 51. Furthermore, the shape of the opening 53 is not limited to a substantially rectangular shape, and may be, for example, a substantially circular shape.

[0048] In the above embodiment, the light bulb set 1 employs a light bulb packaging box 2 that holds the light bulbs 100 at an angle to the central axis of the light bulb packaging box 2, but if no paper accessories are included with the light bulb set 1, the shape of the light bulb packaging box 2 is not limited to this. In other words, if no paper accessories are included with the light bulb set 1, the light bulb packaging box 2 may hold the light bulbs 100 along the central axis of the light bulb packaging box, and any known shape may be used.

[0049] For example, the light bulb packaging box 2 has a rectangular prism shape with a cylindrical body 10, a bottom 20, and a top 30. The interior of the light bulb packaging box 2 includes a holder for holding the light bulb 100 along the central axis of the light bulb packaging box. At least one of the inner or outer surfaces of the cylindrical body 10, the bottom 20, and the top 30 is printed with instructions about the light bulb 100. As described above, the instructions about the light bulb 100 include, for example, product information, handling instructions, installation instructions, precautions, and warranty information. This allows users to receive these instructions without using paper instruction manuals or warranty cards, thereby reducing the amount of paper used for the light bulb 100 instructions and warranty cards. Furthermore, because no paper accessories are included inside the light bulb packaging box 2, this prevents paper from hitting the light bulb packaging box 2 and generating noise during transportation of the light bulb set 1. This prevents users from being negatively affected by the light bulb 100.

[0050] The present disclosure is further illustrated by the following embodiments. Configuration 1: A packaging box for light bulbs has a cylindrical portion consisting of four side panels, a bottom portion, and a top portion, and holds a light bulb at an angle to the central axis of the packaging box for light bulbs.
