Description

[Technical field]

[0001] The present invention relates to a cushioning material for protecting a packaged object from an external impact, and to a packaged object with a cushioning material. [Background technology]

[0002] In recent years, with the development of online sales, the number of cases where packaged items are delivered in boxes has increased dramatically. In order to increase customer satisfaction, it is essential to protect the packaged items from external impacts. For example, Patent Document 1 discloses a cushioning material that is placed in a packaging box (referred to as a box in the document) to protect a packaged object (referred to as a lighting fixture in the document). This cushioning material engages with the packaged object with an instrument fixing piece, and supports the packaged object with a pair of support parts (referred to as holding pieces in the document) provided in the vertical direction (depth direction). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2011-6091 A Summary of the Invention [Problem to be solved by the invention]

[0004] The cushioning material described in Patent Document 1 is formed symmetrically in the up-down and left-right directions (directions perpendicular to the up-down and thickness directions) except for the instrument fixing piece. For this reason, when an impact load including the weight of the package is unevenly applied to the cushioning material supporting the packaged object due to vibrations during transportation or the like, there is room for improvement in mitigating the impact load.

[0005] The present invention has been made in consideration of the above problems, and provides a cushioning material that can suitably absorb impact loads, and a packaged object with the cushioning material. [Means for solving the problem]

[0006] The packaged object with cushioning material of the present invention comprises a packaged object to be packaged in a packaging box, and cushioning material arranged between the packaging box and the packaged object to support the packaged object, wherein the cushioning material comprises a main body portion having a mounting center on which the packaged object is placed, a support portion that supports the packaged object placed on the main body portion, and a plurality of abutment portions located on the four top, bottom and left, right sides of a virtual rectangle circumscribing the main body portion, and is characterized in that, when viewed in a plane, the center of gravity of the virtual rectangle and the mounting center are offset in at least one direction, either the up-down or left-right direction.

[0007] The cushioning material of the present invention comprises a main body portion having a mounting center on which a packaged object is placed, a support portion that supports the packaged object placed on the main body portion, and a plurality of abutment portions located on the four top, bottom and left, right sides of a virtual rectangle that circumscribes the main body portion, and is characterized in that, when viewed in a plane, the center of gravity of the virtual rectangle and the mounting center are offset in at least one direction, either the up-down or left-right direction. Effect of the Invention

[0008] With the cushioning material and the packaged object with cushioning material of the present invention, by setting the positional relationship between the center of placement (support part) and the virtual rectangle so as to increase the gap on the side where impact loads are likely to be applied, it is possible to prevent the support part from colliding with the packaging box (inner surface) or to reduce the collision load, thereby suitably mitigating the impact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, a cushioning-equipped ceiling light 1 and a cushioning material 3 according to an embodiment of the present invention will be described with reference to the drawings. The embodiment described below is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention.

[0011] The drawings used in the present embodiment are intended to illustrate the configuration and shape of the packaged object with cushioning and the cushioning material of the present invention, and the arrangement of each member constituting the packaged object with cushioning and the cushioning material, and are not intended to limit the present invention. Furthermore, the drawings do not necessarily accurately represent the dimensional ratios of the length, width, height, etc. of the packaged object with cushioning and the cushioning material. In this specification, "orthogonal," "vertical," and "parallel" include the range of error permitted in the technical field to which the present invention pertains. For example, in this specification, "orthogonal," "vertical," and "parallel" mean being within a range of less than ±10° from strictly orthogonal, vertical, or parallel. In addition, the error from strictly orthogonal (vertical) or strictly parallel is preferably ±5° or less, and more preferably ±3° or less. In addition, in all drawings, similar components are given the same symbols and descriptions are omitted as appropriate.

[0012] <Summary> First, an overview of the present invention will be described with reference to Fig. 1 and Fig. 2, taking a cushioning-equipped ceiling light 1 according to this embodiment as an example. Fig. 1 is a perspective view showing a packaging set S in which a cushioning-equipped ceiling light 1 is packed in a packaging box 4, and is a view showing the packaging box 4 through which the packaging box 4 is seen. Fig. 2 is a plan view (viewed from the front) of a main body 31 of the cushioning material 3, showing the cushioning material 3 in an unfolded state, and showing that the center of gravity 33a of an imaginary rectangle 33 showing the inner surface of the packaging box 4 is misaligned with the placement center 36 of the ceiling light 2 in the vertical and horizontal directions. In FIG. 2, a part of the skin (front liner or back liner) of the cushioning material 3 is removed to show the corrugations 30 and the corrugation direction of the core.

[0013] As shown in Figure 1, the packaged object with cushioning (ceiling light 1 with cushioning) comprises a packaged object (ceiling light 2) packaged in a packaging box 4, and cushioning material 3 arranged between the packaging box and the packaged object to support the ceiling light 2. As shown in FIG. 2, the cushioning material 3 comprises a main body 31 having a mounting center 36 on which the ceiling light 2 is placed, a support portion 32 that supports the ceiling light 2 placed on the main body 31, and a plurality of abutment portions 34 (34a, 34b, 34c, 34d, 34e) located on the top, bottom, left and right four sides of an imaginary rectangle 33 (the inner surface of the packaging box 4) that circumscribes the main body 31. As shown in FIG. 2, in a plan view of the main body 31, the center of gravity 33a of the imaginary rectangle 33 (packaging box 4) and the center of placement 36 are offset in at least one direction, either the up-down direction or the left-right direction (in this embodiment, both directions).

[0014] The "packaged object" is not limited to the ceiling light 2, but can be applied to any object to be packaged. For example, the packaged object may be a set of a pot and a pot lid, or a set of a vacuum cleaner body and a charging device on which the vacuum cleaner body is placed, all packed in the packaging box 4. In particular, in the case of a ceiling light 2 or the like in which two constituent members move relative to each other after packaging, the cushioning material 3 can effectively suppress interference between the members.

[0015] When the cushioning material 3 or its constituent support portion 32 "supports" the packaged object (ceiling light 2), it means that in the up-down, left-right, and front-to-back directions shown in Figure 1, one portion or the combined structure of multiple portions of the support portion 32 that constitutes the cushioning material 3 is formed larger than at least a part of the ceiling light 2 (encompasses it from the outside) and is formed smaller than the packaging box 4 when the cushioning material 3 is contained in the packaging box 4, thereby restricting the movement of the ceiling light 2 in at least one direction.

[0016] In addition, when the cushioning material 3 is in the form of a blank material before being placed in the packaging box 4, the combined structure of one portion or multiple portions of the support portion 32 constituting the cushioning material 3 is arranged inside the imaginary rectangle 33 (the shape assumed to be the inner surface of the packaging box 4) defined by the abutment portion 34 abutting the inner surface of the packaging box 4, or is formed to be deformable so as to be positioned inside.

[0017] In this embodiment, a specific example of the support portion 32 according to the present embodiment will be described as a preferred example in which a plurality of folded pieces 50 are provided in the circumferential direction of the ceiling light 2, folded back in a U-shape so as to enclose a part of the outer periphery of the ceiling light 2. However, the shape is not limited as long as it can support the packaged object (ceiling light 2). For example, the support portion may be formed by a simple combination structure of protrusions, holes, etc.

[0018] The "imaginary rectangle 33" is a rectangular (square or rectangular) shape shown by a dotted line in Figure 2, which is assumed to be the area in the cushioning 3 where the inner surfaces of the inner surfaces of the packaging box 4 at the top, bottom, left and right are located when the cushioned ceiling light 1 is contained in the packaging box 4. In other words, the "virtual rectangle 33" is the area of ​​the inner surface of the packaging box 4 where the inner surface has an upper side, a lower side, a left side, and a right side that intersect with a cross section parallel to the main body 31 of the cushioning material 3 when the cushioned ceiling light 1 is packed in the packaging box 4.

[0019] The “imaginary rectangle 33 ” is defined by abutment portions 34 on the top, bottom, left and right sides of the cushioning material 3 that circumscribe the inner surface of the packaging box 4 . As shown in Fig. 1, the portions (supporting portions 32, pressure-resistant walls 35) that are folded toward the inside of the packaging box 4 (toward the center of gravity 4b shown in Fig. 2) and do not come into contact with the inner surfaces located at the top, bottom, left, and right of the packaging box 4 constitute the outer edge of the cushioning material 3 in the blank state. However, as shown in Fig. 2, these portions (supporting portions 32, pressure-resistant walls 35) do not correspond to the abutting portions 34 that define the imaginary rectangle 33 on a plane extending in the top, bottom, left, and right directions. In particular, since the inner surfaces of the top, bottom, left and right of the packaging box 4 are rectangular, the imaginary rectangle 33 in this embodiment is composed of the outer edges of the cushioning material 3 that extend parallel to the up-down direction and the left-right direction.

[0020] The vertical and horizontal directions refer to the two directions excluding the direction including the shortest side of the three sides that extend in the three axial directions forming the three-dimensional imaginary rectangular prism that forms the inner surface of the packaging box 4, and if these three sides are even, they refer to any of the directions. "Center of gravity" as used herein is synonymous with the geometric center, which is the location of the arithmetic mean taken over all the points that make up the shape of an article. The packaged object (ceiling light 2) is positioned so that its center of gravity 2a overlaps with the placement center 36 of the cushioning material 3, and is placed on the main body 31 at a position displaced from the center of gravity 33a of the imaginary rectangle 33.

[0021] According to the above configuration, the center of gravity 33a of the virtual rectangle 33 (the shape that divides the inner surface of the packaging box 4) and the mounting center 36 are offset in at least one direction, either up / down or left / right. Therefore, for example, in a case where the ceiling light 2 swings inside the packaging box 4 and the support part 32 approaches the inner surface located above, below, left, or right of the packaging box 4, the positional relationship between the mounting center 36 (support part 32) and the virtual rectangle 33 is set so as to increase the gap on the side that is weaker to impact (especially the side where the glove fastener 21a described later is located, which is subjected to a large impact), thereby preventing the support part 32 from colliding with the packaging box 4 (the inner surfaces located above, below, left, or right).

[0022] As shown in Figure 2, the cushioning material 3 of this embodiment comprises a main body portion 31 having a mounting center 36 on which the packaged object (ceiling light 2) is placed, a support portion 32 that supports the ceiling light 2 placed on the main body portion 31, and a plurality of abutment portions 34 (34a, 34b, 34c, 34d, 34e) located on the top, bottom, left, and right four sides of an imaginary rectangle 33 that circumscribes the main body portion 31. As shown in FIG. 2, in a plan view of the main body 31, the center of gravity 33a of the imaginary rectangle 33 and the center of placement 36 are offset in at least one of the vertical and horizontal directions.

[0023] According to the above configuration, the cushioning material 3 can also provide the same effects as the cushioning-equipped ceiling light 1 described above. A case is assumed in which, when a ceiling light 2 is attached to the cushioning material 3 to form a cushioning-equipped ceiling light 1, which is then housed in a packaging box 4, the ceiling light 2 swings in the packaging box 4, causing the support part 32 to approach the inner surface of the packaging box 4. In this case, the center of gravity 33a of the imaginary rectangle 33 (a shape that defines the inner surface of the packaging box 4) and the mounting center 36 are offset in at least one direction, either vertically or horizontally, and the positional relationship between the mounting center 36 (support part 32) and the center of gravity 33a of the imaginary rectangle 33 is set so as to increase the gap on the side that is weak against shock (particularly the side where a glove fastener 21a described later is located, which is subject to a large shock), thereby preventing the support part 32 from colliding with the packaging box 4 (the inner surface thereof).

[0024] [Package set] Next, the packaging set S as the entire configuration will be described. The packaging set S comprises a packaging box 4, the inner surface of which is indicated by a dotted line in Figure 1, an object (ceiling light 2) to be packaged in the packaging box 4, and cushioning material 3 disposed between the packaging box 4 and the ceiling light 2 to support the ceiling light 2. That is, the packaging set S is composed of a ceiling light 1 with cushioning material, which is a ceiling light 2 to which a cushioning material 3 is attached, and a packaging box 4 in which it is packaged.

[0025] Next, the configuration of each part constituting the packaging set S will be described with reference to FIGS. 3 to 5 in addition to FIGS. Fig. 3 is a schematic explanatory diagram showing an end face around the buffer section 39 in the packaging set S in a normal state, and Fig. 4 is a schematic explanatory diagram showing an end face around the buffer section 39 in the packaging set S in a state in which the ceiling light 2 has climbed up onto the buffer section 39. Fig. 5 is a diagram showing the packaging set S in which the cushioned ceiling light 1 is packed in a packaging box 4, and is a view seen through the packaging box 4 to show the state in which the support section 32 of the cushioning 3 is supporting the ceiling light 2. In addition, the tape 38 is omitted in FIG.

[0026] [Ceiling light] As shown in FIG. 3, the packaged object (ceiling light 2) includes a first member (fixture body 21) and a second member (globe 22) loosely fitted to the fixture body 21 so as to be relatively movable.

[0027] Here, "loosely fitted so as to be relatively movable" refers to a state in which the fitting (engagement) is such that the fitting (engagement) is capable of a predetermined amount of relative movement, but the movement is restricted at a predetermined position. Specifically, the direction of movement may be any of the vertical direction, the horizontal direction, a diagonal direction intersecting with these directions in a virtual plane including the vertical direction and the horizontal direction, or the circumferential direction of the first member (instrument body 21) or the second member (globe 22).

[0028] The device body 21 is a member that is placed on, without being fixed to, the main body portion 31 of the cushioning material 3. The main body portion 31 supports the rear surface (also referred to as the first main surface) of the device body 21. The globe 22 is made of a soft material such as a resin material, and its curved front surface (the front surface in the front-to-rear direction in Figure 1, also called the second main surface) is fixed to the support portion 32 (folded piece 50) of the cushioning material 3 described later by tape 38.

[0029] In this manner, the globe 22 is sandwiched between the support portion 32 and the device body 21. When an external impact is applied to the globe 22 through the packaging box 4 and the cushioning material 3, the globe 22 moves relative to the device body 21. The main surface refers to the surface formed by the axial sides excluding the surface formed by the shortest axial side among the three axial sides that constitute an imaginary rectangular parallelepiped circumscribing the packaged object (ceiling light 2). If the three axial sides are equal, it refers to any of the surfaces.

[0030] A cushioning material 3, the details of which will be described later, is attached to the ceiling light 2. The relative position of the ceiling light 2 with respect to the packaging box 4 is determined by abutment portions 34 (34a, 34b, 34c, 34d, 34e) provided on the top, bottom, left and right of the cushioning material 3 abutting against the inner surface of the packaging box 4.

[0031] As shown in Figure 5, the first member (the fixture body 21 shown in Figure 3) has a plurality of interference portions (globe fasteners 21a) that interfere with the loose movement of the second member (globe 22) and are provided in different numbers above and below the packaged object (ceiling light 2). The globe fastener 21a provided on the device body 21 is for engaging (fitting) with the globe 22. The globe fastener 21a is provided on the front side (the side facing the globe 22) of the device body 21 in FIG. 3 so as to protrude from the surroundings. The globe 22 is configured to engage with the globe fastener 21a when a part of the globe 22 moves beyond a certain portion of the abutment portion with the globe fastener 21a provided on the instrument body 21. When the globe 22 moves to a predetermined position in the circumferential direction with respect to the instrument body 21, the instrument body 21 and the globe 22 are loosely fitted together until the globe fastener 21a abuts (interferes with) a part of the globe 22.

[0032] As shown diagrammatically in Figure 5, three globe fasteners 21a in this embodiment are provided at approximately 120 degree intervals in the circumferential direction around the center of gravity 2a of the ceiling light 2, with one on the upper side and two on the lower side.

[0033] [Cushioning material] The cushioning material 3 is intended to cushion the ceiling light 2 from an external shock applied via the packaging box 4. The cushioning material 3 is made of cardboard, and as shown in Fig. 2 and described above, includes a main body 31 having a mounting center 36 on which the ceiling light 2 is placed, a support portion 32 that supports the ceiling light 2 placed on the main body 31, and a plurality of contact portions 34 (34a, 34b, 34c, 34d, 34e) located on the top, bottom, left, and right four sides of an imaginary rectangle 33 (the inner surface of the packaging box 4) that circumscribes the main body 31. The main body 31 is located at the center of the cushioning material 3 in the up-down and left-right directions, has the placement center 36 as described above, and is a part that extends up-down and left-right in a flat shape without being folded.

[0034] 1 and 2, the support part 32 is a folded piece 50 (a first folded piece 51, a second folded piece 52, a third folded piece 53, and a fourth folded piece 54) that is folded from the main body part 31 at folding lines 51a, 52a, 53a, and 54a and has folding parts 51b, 52b, 53b, and 54b that are located on the tip side of the folding lines 51a, 52a, 53a, and 54a. The folded pieces 50 support the packaged object (ceiling light 2) by sandwiching it between the main body part 31 and the folded piece 50. The first member (instrument body 21) is not fixed to the folded piece 50. The second member (globe 22) is fixed to the folded piece 50 at least in part.

[0035] 2, in the unfolded state (blank state) of the cushioning material 3 according to this embodiment, the first folded piece 51 extends upward and the second folded piece 52 extends leftward relative to the main body 31 (based on the main body 31). In the unfolded state (blank state) of the cushioning material 3, the third folded piece 53 extends downward and the fourth folded piece 54 extends rightward relative to the main body 31. The first folded piece 51, the second folded piece 52, the third folded piece 53, and the fourth folded piece 54 are each formed to have a uniform thickness. Naturally, these thicknesses are also formed to be uniform when viewed in a plan view.

[0036] The multiple fold-over pieces 50 in this embodiment are configured to be folded back at the same length from the top, bottom, left, and right directions toward the center of the ceiling light 2 when no impact force is applied to the packaging box 4 (packaging set S), thereby evenly supporting the ceiling light 2. In other words, the folding lines 51 a , 52 a , 53 a , and 54 a that are the folding base ends of the folding piece 50 are formed at positions that are the same distance from the mounting center 36 of the ceiling light 2 . In other words, in this embodiment, the placement center 36 is the intersection of line segments connecting the midpoints of the opposing folding lines 51a, 52a, 53a, and 54a.

[0037] In this embodiment, an example in which four folded pieces 50 are provided is shown, but the present invention is not limited to this configuration. Only one folded piece 50 may be provided, or five or more folded pieces 50 may be provided.

[0038] According to the above configuration, since the folded piece 50 is fixed to the second member (globe 22), even a packaged object including the second member (globe 22) that is loosely fitted and movable relative to the first member (apparatus main body 21) can be held in an appropriate manner.

[0039] 5, when the ceiling light 2 is divided in the vertical direction, the gap D1 between the inner surface of the packing box 4 on the side with a larger number of globe fasteners 21a (the lower side in this embodiment) and the support part 32 is smaller than the gap D2 between the inner surface of the packing box 4 on the side with a smaller number of globe fasteners 21a (the upper side in this example) and the support part 32. In this embodiment, the gap D1 on the lower side is 4.5 mm, and the gap D2 on the upper side is 27.5 mm. The gap D2 is preferably at least two times, and more preferably at least five times, and more preferably at most ten times, and more preferably at most seven times, the gap D1.

[0040] According to the above configuration, the more glove fasteners 21a there are, the smaller the impact force applied to each glove fastener 21a, so even if the gap is reduced and the amount of deflection of the folded piece 50 (support portion 32) is limited, it is possible to prevent the glove fastener 21a from being subjected to a large external impact.

[0041] In the present embodiment, the ceiling light 2 is exemplified as the packaged object, and the globe fastener 21a is exemplified as the interference portion, but the present invention is not limited to such a configuration. The packaged object is not limited to the ceiling light 2, and may be any object in which an interference portion is provided by loosely fitting a first member (the fixture body 21) and a second member (the globe 22). In other words, even for packaged objects other than the ceiling light 2, by maintaining the relationship between the gap between the inner surface of the packaging box 4 and the support part 32 and the position of the interference part in the same relationship as above, it is possible to prevent large impacts from being applied to the interference part.

[0042] As shown in FIG. 2, the cushioning material 3 is provided with a cushioning portion 39 including at least a portion (contact portion 34e) of the multiple contact portions 34 (34a, 34b, 34c, 34d, 34e), and is to be contained in a packaging box 4.

[0043] The buffer section 39 is arranged to abut against the inner surface of the packing box 4 or to be able to abut in a predetermined state, thereby cushioning the impact of the packing box 4. In FIG. 2, the buffer section 39 comprises a first buffer section 40 provided in the upper left corner of the imaginary rectangle 33, and a second buffer section 41 provided in the lower right corner. 2, when the cushioning material 3 is viewed from the front in the front-rear direction, the angle of a virtual line segment (not shown) extending rightward from the center of placement 36 is set to 0 degrees, with the counterclockwise direction being positive and the clockwise direction being negative. At this time, the first cushioning section 40 is disposed at a position of approximately +135 degrees (including an error of about ±5 degrees) with respect to the center of placement 36, and the second cushioning section 41 is disposed at a position of approximately -45 degrees (including an error of about ±5 degrees).

[0044] The first buffer section 40 is configured so that, when the cushioned ceiling light 1 is contained within the packaging box 4, the upper and left edges of the first buffer section 40 abut against the upper and left sides of the inner surface of the packaging box 4. The second buffer section 41 is configured such that, when the cushioned ceiling light 1 is contained within the packaging box 4, the lower edge and right edge of the second buffer section 41 abut against the lower side and right side of the inner surface of the packaging box 4.

[0045] With this configuration, as shown in FIG. 2, the first buffer section 40 can absorb impacts on the upper and left sides of the packing box 4, and the second buffer section 41 can absorb impacts on the lower and right sides of the packing box 4. In addition, the buffer section 39 according to this embodiment is composed of a first buffer section 40 and a second buffer section 41, but is not limited to such a configuration, and the number or arrangement thereof can be set arbitrarily.

[0046] 1 and 2, at least one pair of folded pieces 50 (first folded piece 51 and third folded piece 53) is provided on the top and bottom, and at least one pair (second folded piece 52 and fourth folded piece 54) is provided on the left and right. The shortest distances (lengths L1, L2, L3, L4) between the imaginary rectangle 33 and the respective folding lines (folding lines 51a and 53a or folding lines 52a and 54a) of at least one pair of folded pieces (first folded piece 51 and third folded piece 53 or second folded piece 52 and fourth folded piece 54) are different in at least one of the up-down direction and the left-right direction.

[0047] The cushioning material 3 of this embodiment is provided with a pair of upper and lower first fold pieces 51 and third fold pieces 53, and a pair of left and right fold pieces 52 and fourth fold pieces 54, and is advantageous in that it can support the ceiling light 2 in both the vertical and horizontal directions.

[0048] However, the present invention is not limited to such a configuration, and may be configured with only a pair of the first folded piece 51 and the third folded piece 53, or only a pair of the second folded piece 52 and the fourth folded piece 54. Furthermore, the folded pieces may be configured with only three pieces provided at intervals around the mounting center 36 when viewed from the front side in the front-rear direction.

[0049] The difference in the shortest distance between the folding lines (folding lines 51a and 53a or folding lines 52a and 54a) of the pair of folding pieces 50 and the virtual rectangle 33 means that the distance between the folding lines (folding lines 51a and 53a or folding lines 52a and 54a) at which the folding pieces 50 rise and the virtual rectangle 33 defined by the abutting portion 34 is different. When this distance is different, the distance between the folding piece 50 on the longer side and the abutting portion 34 (the inner surface of the packaging box 4) is greater than the distance between the folding piece 50 on the shorter side and the abutting portion 34 (the inner surface of the packaging box 4). The greater the distance, the wider the range in which the folding piece 50 can support the ceiling light 2. When an external impact is applied and the main body 31 of the ceiling light 2 moves in the up-down or left-right direction, the higher the upper limit of the external impact that can be tolerated can be increased.

[0050] Specifically, with regard to the gaps between each of the first folded piece 51, the second folded piece 52, the third folded piece 53, and the fourth folded piece 54 of the cushioning material 3 and the inner surface of the packaging box 4, as shown in FIG. 5, the lower gap D1 is 4.5 mm, the upper gap D2 is 27.5 mm, the left gap D3 is 20 mm, and the right gap D4 is 7 mm. These gaps D1 to D4 are determined by subtracting the length from the mounting center 36 to the outer end of the abutment portion 34 that defines the inner surface of the packaging box 4 when the cushioning material 3 shown in Figure 5 is viewed in a plane, from the length from the mounting center 36 to the outer end of the fold-over piece 50 when folded over to support the ceiling light 2. The gap D3 is preferably at least twice as large as the gap D4, and is preferably at most five times as large as the gap D4.

[0051] The reason for providing gaps D1 to D4 in this manner is to prevent the ceiling light 2 from coming into contact with the inner surface of the packaging box 4 through the folded piece 50, or to reduce the impact force when it does come into contact with this. Furthermore, the gaps D1 and D2, and the gaps D3 and D4 are of different sizes in order to suitably protect the ceiling light 2 when durability against external impact forces differs between the top and bottom or the left and right of the ceiling light 2. In other words, by making the above-mentioned gaps larger on the side with lower durability, it is possible to suitably reduce impact forces on the side with lower durability.

[0052] Specifically, even if the device body 21 moves due to an external impact force, the large gap increases the range within which the folded-back piece 50 can be displaced, and the movement of the device body 21 can be accommodated. Therefore, the impact caused by contact between the globe 22 arranged on the device body 21 and the inner surface of the packaging box 4 can be mitigated.

[0053] When an impact force is applied to the packaging box 4 from the outside, the instrument body 21 that is not fixed to the main body 31 moves on the main body 31. In this case, since the folded piece 50 is fixed to the second member (globe 22), it can deform so as to stand down in a side view from the fixed point as shown in Fig. 4. When the instrument body 21 moves and presses the folded piece 50, the contact part of the folded piece 50 with the instrument body 21 shifts toward the tip side, and the folded piece 50 deforms so as to bulge in the pressing direction of the instrument body 21. In other words, the length of the base end side of the folded piece 50 that is an extension of the main body 31 becomes longer, and the length of the folded portion that rises up from the main body 31 becomes shorter. This increase in the range in which the base end side of the folded piece 50 can be displaced is referred to as "the range in which the folded piece 50 can be displaced becomes larger" above.

[0054] In addition, for example, when an impact force is applied from the outside of the packaging box 4, and the globe 22 abuts against the inner surface of the packaging box 4 through the folded piece 50, the movement of the globe 22 is restricted. In this state, the device body 21, whose movement is not restricted, moves relative to the globe 22, and the globe fastener 21a provided on the device body 21 may interfere with a part of the globe 22.

[0055] As described above, by providing gaps D1 to D4, indirect contact (abutment) between the glove 22 and the inner surface of the packaging box 4 through such folded piece 50 is prevented, or the impact force is reduced, thereby preventing the glove fastener 21a from interfering with part of the glove 22.

[0056] The cushioning material 3 has a plurality of contact portions 34 (34a, 34b, 34c, 34d, 34e) that contact the inner surface of the packaging box 4 from above, below, left and right. Specifically, the abutment portion 34 includes abutment portion 34a that abuts against the inner surface of the packing box 4 on the upper side of the main body portion 31, abutment portion 34b that abuts against the inner surface of the packing box 4 on the left side of the main body portion 31, abutment portion 34c that abuts against the inner surface of the packing box 4 on the lower side of the main body portion 31, abutment portion 34d that abuts against the inner surface of the packing box 4 on the right side of the main body portion 31, and abutment portion 34e that abuts against the inner surface of the packing box 4 on the lower and right side of the second buffer portion 41. Since the contact portion 34 of the cushioning material 3 contacts the inner surface of the packaging box 4, the cushioning material 3 basically does not move up and down or left and right with respect to the packaging box 4. However, when the packaging set S is swayed up and down and left and right during transportation, etc., the inertial force of the ceiling light 2 may cause the support portion 32 (the folded-back piece 50) to bend and become displaced.

[0057] As shown in FIG. 2, at least a part of the buffer section 39 (second buffer section 41) is formed continuous with the bent portions 53b, 54b of the adjacent folded-back pieces 50. As shown in FIG. A surface defined by a part of the outer surface 31a (rear surface) of the main body 31 is defined as a virtual inner surface (outer surface 31a of the main body 31) indicating the inner surface of the packaging box 4 that is in surface contact with a part of the outer surface 31a of the main body 31. At least a part of the buffer section 39 (second buffer section 41) is formed continuously with the folded parts 53b, 54b of the fold-back piece 50 as shown in FIG. 2. Therefore, in a state in which the fold-back piece 50 supports the ceiling light 2 (a state in which the fold-back piece 50 is fixed to the globe 22 by the tape 38), at least a part of the buffer section 39 (second buffer section 41) rises up from the main body 31 together with the fold-back piece 50, and is disposed apart (floating) from the virtual inner surface (a plane including the outer surface 31a of the main body 31).

[0058] Here, the "virtual inner surface" refers to an inner surface of the packaging box 4 that is assumed to be in contact with the surface of the main body 31 opposite to the placement surface on which the ceiling light 2 is placed (the rear surface in the front-to-rear direction in this embodiment) when the cushioned ceiling light 1 is housed in the packaging box 4. Since the outer surface 31a of the main body 31 and the inner surface of the packaging box 4 are in face-to-face contact, the outer surface 31a of the main body 31 is substantially identical to the virtual inner surface, and the inner surface of the packaging box 4 is defined by this outer surface 31a.

[0059] According to the above configuration, at least a part of the buffer section 39 (second buffer section 41) is formed continuously with the bent sections 53b, 54b, and by folding back the third folded piece 53 and the fourth folded piece 54, the buffer section (second buffer section 41) continuous with the bent sections 53b, 54b is disposed so as to be separated (floated) forward in the front-to-back direction from the imaginary inner surface (outer surface 31a of the main body section 31) defined by the outer surface of the main body section 31. Therefore, the second buffer section 41 can suitably mitigate the impact applied to the center side (between both main surfaces) of the packaged object (ceiling light 2) in its thickness direction (front-to-back direction in FIG. 1).

[0060] In particular, it is preferable that at least a portion of the buffer section 39 (second buffer section 41) disposed away from the imaginary inner surface (outer surface 31a of the main body section 31) abuts against the inner surface of the packaging box 4 in a direction intersecting the imaginary inner surface (outer surface 31a of the main body section 31). According to the above configuration, at least a part of the buffer section 39 (second buffer section 41) abuts against the inner surface of the packaging box 4, so that the impact force on the buffer material 3 can be reduced and the buffering effect can be improved. Furthermore, by abutting against the inner surface of the packaging box 4 in a direction intersecting the inner surface, the force applied to the lower edge of the buffer section 39 (second buffer section 41) can be dispersed.

[0061] By mitigating the impact force from the outside of the packaging box 4, it is possible to reduce the movement of the device main body 21 caused by the impact force. Therefore, in the main body 31, it is possible to suppress interference with a part of the globe 22 caused by the movement of the globe fastener 21a located near the second buffer part 41.

[0062] In particular, it is preferable that the direction in which the second buffer portion 41 extends outward from the second fold 41c described below is the anti-step direction (perpendicular to the step direction). The anti-step direction is preferable for protecting the ceiling light 2 because it is easier to bend in a manner that envelops the ceiling light 2 compared to the step direction.

[0063] The second buffer section 41 has a configuration formed continuously with the bent portions 53b, 54b, that is, a configuration different from the first buffer section 40 in which a slit 40b is formed between each of the first folded piece 51 and the second folded piece 52. For this reason, the second buffer section 41 can have a higher rigidity than the first buffer section 40 against an external force in a direction perpendicular to the step 30 (in other words, a direction in which the first buffer section 40 and the second buffer section 41 are bent).

[0064] In this embodiment, the buffer section 39 is exemplified by a configuration including a first buffer section 40 in which a slit 40b is formed between the first folded piece 51 and the second folded piece 52, and a second buffer section 41 that is continuous with the folded portion 53b of the third folded piece 53 and the folded portion 54b of the fourth folded piece 54.

[0065] With this configuration, as described above, the second buffer portion 41 can suitably protect the center side of the ceiling light 2 in the thickness direction (the front-rear direction in FIG. 1). Furthermore, since a slit 40b is formed between the first buffer section 40 and each of the first folded piece 51 and the second folded piece 52, when the first folded piece 51 and the second folded piece 52 are raised and folded back against the main body section 31, the first buffer section 40 is less likely to rise up toward the center of the thickness direction of the ceiling light 2.

[0066] This prevents the first buffer section 40, which is formed to be difficult to rise on the center side of the thickness direction of the ceiling light 2, from impeding the movement of the ceiling light 2 supported by the first folded piece 51 and the second folded piece 52. This allows the first buffer section 40 provided in the upper left corner to improve the freedom of movement of the ceiling light 2 in the upward and leftward directions. Therefore, an impact applied from the outside to the packaging set S composed of the packaging box 4 containing the cushioned ceiling light 1 can be absorbed by the second buffer section 41 and dissipated diagonally upward and to the left by the first buffer section 40. However, the present invention is not limited to this configuration, and a pair of second buffer sections 41 may be provided at opposing corners, or a plurality of second buffer sections 41 alone may be provided.

[0067] As described above, the first buffer section 40 is not formed continuously with the folded portions 51b, 52b of at least one (the first folded portion 51 or the second folded portion 52) of the folded portion 50. In other words, the first buffer section 40 is formed discontinuously with the folded portions 51b, 52b. The second buffer portion 41 is formed continuously with the folded portions 53b, 54b of at least one of the folded pieces 50 (the third folded piece 53 or the fourth folded piece 54).

[0068] Focus on the first folded piece 51 and the third folded piece 53, which are located above and below. As shown in Fig. 2, when the length from the folding line 51a to the contact portion 34a closest to the folding line 51a on the first buffer section 40 side is defined as a first length L1, and the length from the folding line 53a to the contact portion 34c closest to the folding line 53a on the second buffer section 41 side is defined as a second length L3, the first length L1 is longer than the second length L3. Also, attention will be paid to the second folded piece 52 and the fourth folded piece 54 on the left and right sides. As shown in Fig. 2, when the length from the folding line 52a to the contact portion 34b closest to the folding line 52a on the first buffer section 40 side is defined as a first length L2, and the length from the folding line 54a to the contact portion 34d closest to the folding line 54a on the second buffer section 41 side is defined as a second length L4, the first length L2 is longer than the second length L4.

[0069] As described above, the bending lines 51a, 52a, 53a, and 54a are formed at positions that are the same distance from the mounting center 36 of the ceiling light 2. The imaginary rectangle 33 is determined by the contact portions 34a, 34b, 34c, and 34d (and 34e). As shown in FIG. 2 and described above, in the up-down direction, the first length L1 from the folding line 51a to the abutment portion 34a is different from the second length L3 from the folding line 53a to the abutment portion 34c, and in the left-right direction, the first length L2 from the folding line 52a to the abutment portion 34b is different from the second length L4 from the folding line 54a to the abutment portion 34d. For this reason, the mounting center 36 formed at a position the same distance from the bending lines 51a, 52a, 53a, 54a and the center of gravity 33a of the virtual rectangle 33 determined by the abutment portions 34a, 34b, 34c, 34d (, 34e) formed at positions of different lengths in the up-down and left-right directions from the bending lines 51a, 52a, 53a, 54a are positioned offset from each other.

[0070] In this embodiment, the first length L1, which is the length in the up-down direction, is 89.5 mm, the second length L3 is 67.5 mm, and the first length L2, which is the length in the left-right direction, is 82 mm, and the second length L4 is 69 mm.

[0071] According to the above configuration, the first length (L1 or L2) of the first buffer section 40 that is not formed continuously with the bending sections 51b, 52b is longer than the second length (L3 or L4) of the second buffer section 41 that is formed continuously with the bending sections 53b, 54b, thereby preventing impact force from being applied to the packaged object (ceiling light 2) via the packaging box 4 on the first buffer section 40 side.

[0072] 2, the buffer section 39 (second buffer section 41) is provided with a fold (second fold 41c) that extends in a direction perpendicular to the folding direction of the buffer section 39 and serves as a boundary with the main body section 31. In other words, the "direction perpendicular to the folding direction" refers to a direction perpendicular to a plane that includes the folding path.

[0073] According to the above configuration, the second cushioning section 41 is provided with the second fold 41c, which makes it easier to fold the second cushioning section 41 relative to the main body section 31. Therefore, the second cushioning section 41 can be inclined relative to the main body section 31 with the second fold 41c as a reference, and the tip section at the folded end of the second cushioning section 41 can be disposed close to the ceiling light 2 placed on the main body section 31. As a result, even if an impact is applied to the center side (between both main surfaces) where the ceiling light 2 is disposed, the impact can be effectively mitigated by the second cushioning section 41 folded at the second fold 41c, and the effect of the impact on the ceiling light 2 can be reduced.

[0074] In this way, the second buffer section 41 is connected to the adjacent third folded piece 53 and fourth folded piece 54 by the folding lines 53c and 54c without any complete break. The folding line 54c makes the second buffer section 41 easy to fold with respect to the third folded piece 53 and the fourth folded piece 54. With this configuration, the second buffer section 41 fills the gap in the vertical direction with respect to the packaging box 4 while extending in a direction obliquely intersecting the lower inner surface and the rear inner surface of the packaging box 4 as described above. Therefore, the second buffer section 41 has a higher ability to absorb impact than the first buffer section 40 that does not have the second fold 41c.

[0075] Therefore, even if the distance between the third fold piece 53 and the fourth fold piece 54, which are adjacent to the second buffer section 41 and support the ceiling light 2, and the inner surface of the packaging box 4 (virtual rectangle 33), is shortened, the second buffer section 41 can effectively mitigate the impact applied to the ceiling light 2 (especially the globe 22 when it comes into contact with the globe fastener 21a) from the inner surface of the packaging box 4 via the third fold piece 53 and the fourth fold piece 54.

[0076] Specifically, as shown in FIG. 5 and described above, even if the gap D1 between the lower inner surface of the packing box 4 and the third fold piece 53 is made smaller than the gap D2 between the upper inner surface of the packing box 4 and the first fold piece 51, the second buffer section 41 will effectively absorb external impacts applied from below, similar to the absorption of impacts applied from above. Similarly, even if the gap D4 between the inner right side of the packing box 4 and the fourth fold piece 54 is made smaller than the gap D3 between the inner left side of the packing box 4 and the second fold piece 52, the second buffer section 41 will effectively absorb external impacts applied from the right, just as it absorbs impacts applied from the left.

[0077] In particular, the second buffer section 41 is folded at the second fold 41c and extends in a direction that crosses obliquely with the lower inner surface and the rear inner surface of the packaging box 4. As shown in Fig. 4, when an impact force is applied to the packaging box 4, the appliance body 21 can move up to the second buffer section 41. However, in that case, the appliance body 21 rides on the second buffer section 41, and the downward movement of the appliance body 21 can be restricted. Furthermore, the second buffer portion 41 extending obliquely forward and downward can dissolve and mitigate the impact force applied to the packaging box 4 from below to above in the front-rear direction as well.

[0078] As described above, it is preferable that the second cushioning section 41 has the second fold 41c, but this is not limited to the configuration, and the second cushioning section 41 does not necessarily have to have the second fold 41c.

[0079] Bend lines 53c, 54c are provided between the third folded piece 53 and the second buffer section 41 and between the fourth folded piece 54 and the second buffer section 41, respectively. The folding lines 53c, 54c are formed by half-cutting the surface layer (front liner or back liner) on the side where the ceiling light 2 is placed, and are configured to be mountain-foldable (protruding forward). The third folded piece 53 and the fourth folded piece 54 are mountain-folded with respect to the folding lines 53c, 54c with respect to the second buffer section 41, and are configured to be folded back so as to encase the ceiling light 2.

[0080] 2, the second buffer section 41 has a first fold 41b extending along the folding direction of the buffer section 39 and a second fold 41c extending in a direction perpendicular to the folding direction. The first buffer section 40 does not have the first fold 41b, but has the second fold 40c. A hole 31b is formed on the second buffer section 41 side at the intersection between an extension of the first fold 41b and an extension of the second fold 41c. No hole 31b is formed on the second fold 40c on the first buffer section 40 side.

[0081] The above-mentioned "folding direction of the buffer section 39" refers to a direction on a plane that is parallel to a plane that includes a folding path of the buffer section 39 relative to the main body section 31, in the buffer material 3 in the blank state shown in Fig. 2. In other words, this "folding direction of the buffer section 39" refers to a direction perpendicular to the second fold 40c or the second fold 41c. Hole 31b is preferably a through hole, but may also be a bottomed hole that penetrates only the front liner or the back liner, or that penetrates only the front liner or the back liner and the core, and does not penetrate all the way to the liner on the opposite side from the side where hole 31b is formed.

[0082] According to the above configuration, the formation of hole 31b can prevent the formation of corners where first fold 41b and second fold 41c intersect, which are prone to breakage, and does not hinder the bending deformation of first fold 41b and second fold 41c. Furthermore, when the folding lines 53c, 54c are folded in a mountain shape (convex toward the front), the thickness of the cushioning material 3 is not concentrated at the ends of the folding lines 53c, 54c on the main body 31 side (preventing stress concentration), and the folding properties of the folding lines 53c, 54c can be improved.

[0083] The second fold 40c may not be formed in the first buffer section 40. If the second fold 40c is not formed in this way, the first buffer section 40 at the upper left corner is less likely to bend, and the contact position of the first buffer section 40 with the inner surface of the upper side and the left side of the packaging box 4 is stabilized. Therefore, it is possible to prevent the buffer material 3 including the first buffer section 40 from shifting upward and leftward relative to the packaging box 4.

[0084] The first fold 41b makes it easier to position the tip of each of the third folded piece 53 and the fourth folded piece 54 adjacent to the second buffer section 41 in front of the ceiling light 2. The first fold 41b is provided in pairs at the lower left and upper right of the second buffer section 41, and is folded in a valley shape (convex toward the rear). First fold 41b is formed by a plurality of linear through holes formed in a perforated pattern, and has higher rigidity than folding lines 53c, 54c formed by half-cutting.

[0085] By forming the first fold 41b in this manner, the side surfaces (side surfaces formed in a V-shape (or U-shape)) of the portions of the right and lower contact portions 34e of the buffer portion 39 that are folded at the first fold 41b can be given higher rigidity against a load applied perpendicularly to the side surfaces than other portions. In other words, the side surfaces that are folded across the first fold 41b can be brought into contact with the inner surface of the packaging box 4. The second fold 41c is a linear portion compressed in the thickness direction, and no cut or hole is formed therein.

[0086] In particular, the side surfaces of the portions of the right and lower contact portions 34e of the buffer portion 39 that are folded at the first fold 41b are formed so as to intersect in a direction perpendicular to the step direction (opposite the step direction). By forming the side surfaces of the portions in this manner, it is possible to impart high rigidity to the side surfaces of the portions.

[0087] In particular, in this embodiment, hole 31b is formed at the intersection of the extension line of folding line 53c, which is a mountain fold, and the extension line of folding line 54c, which is a valley fold, and the extension line of second fold 41c, which is a valley fold, thereby preventing the creation of corners where loads are more likely to concentrate and be damaged. In addition, the hole 31b can divide the folding lines 53a, 53c, the first fold 41b, the second fold 41c, and the folding line 54c, making it easier to fold each of them independently. Furthermore, the hole 31b can prevent the folding lines 53a, 53c, the first fold 41b, the second fold 41c, and the folding line 54c from progressing.

[0088] The cushioning material 3 has pressure-resistant walls 35 that support the packing box 4 from the inside in the thickness direction (front-rear direction in FIG. 1). The pressure-resistant walls 35 abut against both sides of the inner surface of the packing box 4 in the short length direction to increase the strength of the packing box 4. 2, a pair of pressure-resistant walls 35 according to this embodiment are provided at the upper right corner and the lower left corner in the step direction, and are connected to the main body 31 by creases 35a (folds) extending perpendicular to the step direction (anti-step direction). The pressure-resistant walls 35 are erected perpendicular to the main body 31 (including approximately perpendicular with a range of about ±10 degrees) with the creases 35a as the starting point.

[0089] It is preferable that the pressure-resistant wall 35 is provided on the lower side of the packaging box 4 in particular. According to the above configuration, by forming a support point by the pressure-resistant wall 35 on the lower side of the packaging box 4, it is possible to improve the strength in the thickness direction on the lower side to which the weight of the cushioned ceiling light 1 is applied.

[0090] In particular, the line 35a in the upper right corner extends at an angle of approximately 45 degrees relative to the upper contact portion 34a of the main body 31 and the right contact portion 34d. Moreover, the line 35a at the lower left corner extends at an angle of approximately 45 degrees relative to the left contact portion 34b of the main body 31 and the lower contact portion 34c.

[0091] In this way, by forming the line 35a in the upper right corner, the strength against loads from above and the right can be increased at the intersection (fold point) between the end of the line 35a of the pressure-resistant wall 35 and the main body 31. Similarly, the formation of the line 35a at the lower left corner increases the strength against loads from below and the left at the intersection (fold point) between the end of the line 35a of the pressure-resistant wall 35 and the main body 31.

[0092] In the above-described embodiment, the top-bottom direction and the left-right direction of the packaged object (ceiling light 2) and the cushioning material 3 are defined and then described. However, the present invention is not limited to this, and the packaged object and the cushioning material may be configured in such a way that the up-down and left-right directions are reversed from those in the above-described embodiment. The vertical direction and the direction of gravity do not necessarily coincide.

[0093] The packaged object is not limited to an asymmetric structure. For example, even if the packaged object is an equal member (a device that is symmetrical vertically and horizontally), if the fragile part is located at an offset position, it may be better to store the packaged object at an offset position relative to the packaging box 4 so as to protect the fragile part. In this case, it is preferable that the center of gravity 4b of the packaging box 4 (center of gravity 33a of the imaginary rectangle 33) and the center of gravity of the packaged object are offset.

[0094] The cushioning material 3 according to the present embodiment has been described as having a configuration including the pressure-resistant wall 35, the support portion 32, and the cushioning portion 39, but this is merely an example. In other words, the number and arrangement of each portion constituting the cushioning material may be changed as appropriate. For example, the cushioning material may not have the pressure-resistant wall 35 or the support portion 32 depending on its structure.

[0095] Furthermore, the various components of the cushioning-equipped ceiling light 1 according to the present invention do not need to exist independently of one another. It is acceptable for multiple components to be formed as one member, for one component to be formed from multiple members, for one component to be a part of another component, or for part of one component to overlap with part of another component.

[0096] The present embodiment encompasses the following technical ideas.
