Description

本開示は、包装箱に関する。 The present disclosure relates to a packaging box.

従来、包装箱としては、特許文献１に記載されているように、１枚のシート状の段ボールを中空の直方体形状に折り畳んで形成されたものがある。また、段ボールは、例えば、図５に示す断面を有し、波型に形成した中芯２６２と、中芯２６２の厚さ方向の両側に貼合されたライナー２６１と呼ばれる厚紙を含む。中芯２６２は、一方向に関して波型に変形する厚紙であり、一方向に直交する直交方向では、直線状に延在する。段ボールにおいて、上記直交方向は、目方向と呼ばれる。なお、図５は、１重構造の段ボールを表す断面図であるが、段ボールは、２重以上の構造であってもよい。例えば、２重構造の段ボールの場合、平行に配置された３つのライナーと２つの中芯を有し、各中芯は、隣り合う各２つのライナーの間に貼合される。また、３重構造の段ボールの場合、平行に配置された４つのライナーと３つの中芯を有し、各中芯は、隣り合う各２つのライナーの間に貼合される。 Conventionally, as a packaging box, there is a packaging box formed by folding a sheet of corrugated cardboard into a hollow rectangular parallelepiped shape. The corrugated cardboard includes, for example, a corrugated inner core 262 having a cross section shown in FIG. 5 and cardboard called a liner 261 bonded to both sides of the inner core 262 in the thickness direction. The center core 262 is a cardboard that is deformed into a corrugated shape with respect to one direction, and extends linearly in the orthogonal direction orthogonal to the one direction. In the cardboard, the orthogonal direction is called the eye direction. Note that FIG. 5 is a cross-sectional view showing a single-layer cardboard, but the cardboard may have a double-layer structure. For example, in the case of a cardboard having a double structure, it has three liners and two cores arranged in parallel, and each core is bonded between two adjacent liners. In the case of a triple-layered cardboard, it has four liners and three cores arranged in parallel, and each core is bonded between two adjacent liners.

The X direction, the Y direction, and the Z direction are orthogonal to each other.

図１は、組み立てられている最中の本開示の一実施形態に係る包装箱１を示す模式図である。包装箱１は、光出射側の端部にフランジを有する埋込式の照明装置（所謂、ダウンライト）を収納するために用いられる。そのような照明装置は、取付バネを有し、取り付けバネをホール等の天井に設けられた円筒孔に係止することで天井に固定される。図１に示すように、包装箱１は、箱本体１０と、緩衝材８０を備え、箱本体１０は、箱部１１と、柱部１２を含む。箱部１１は、折目が形成されたシート状の一枚の段ボールを折目に沿って折り込んだ際に箱形状に形成される部分である。 FIG. 1 is a schematic diagram illustrating a packaging box 1 according to an embodiment of the present disclosure being assembled. The packaging box 1 is used to house an embedded illumination device (so-called downlight) having a flange at the end on the light emission side. Such an illuminating device has an attachment spring, and is fixed to the ceiling by locking the attachment spring in a cylindrical hole provided in a ceiling such as a hall. As shown in FIG. 1, the packaging box 1 includes a box body 10 and a cushioning material 80, and the box body 10 includes a box part 11 and a pillar part 12. The box portion 11 is a portion that is formed in a box shape when a sheet of corrugated cardboard on which a fold is formed is folded along the fold.

柱部１２は、箱部１１が箱状に形成される際に箱部１１内側の角部に高さ方向に起立するように形成される。柱部１２は、各角部に関して、その角部を画定する２つの側壁部１５〜１８のうちの１つの側壁部１５〜１８に対して略３０°〜６０°傾斜するように箱部１１の角から箱部内側に所定距離延在する。本実施例では、図１に示すように、該１つの側壁部１５〜１８に対して略４０°〜５０°傾斜するように箱部１１の角から箱部１１内側に所定距離延在する。柱部１２の詳しい構造については、後で図２〜図４を用いて詳細に説明する。 The column portion 12 is formed so as to stand in the height direction at a corner portion inside the box portion 11 when the box portion 11 is formed in a box shape. The column part 12 of the box part 11 is inclined about 30 ° to 60 ° with respect to one side wall part 15 to 18 of two side wall parts 15 to 18 defining the corner part with respect to each corner part. A predetermined distance extends from the corner to the inside of the box. In the present embodiment, as shown in FIG. 1, a predetermined distance extends from the corner of the box portion 11 to the inside of the box portion 11 so as to be inclined approximately 40 ° to 50 ° with respect to the one side wall portion 15 to 18. The detailed structure of the column portion 12 will be described in detail later with reference to FIGS.

緩衝材８０は、シート状の段ボール、シート状の厚紙、又はシート状の発泡スチロール等で構成され、照明装置が接触しても照明装置が傷つかないシート状の素材で構成される。緩衝材８０は、略矩形の縁部８１を有し、この縁部８１は、高さ方向上側から見たとき、箱部１１の底壁部１４の縁部１４ｂ,１４ｃに重なるように配置される。緩衝材８０の縁部端面は、箱部１１が箱状に組み立てられた際、箱部１１の４つの側壁部１５〜１８で内側に押圧され、その結果、緩衝材８０は、高さ方向に垂直な方向（以下、この方向を水平方向という）が４つの側壁部１５〜１８で位置決めされる。 The cushioning material 80 is made of a sheet-like cardboard, a sheet-like cardboard, a sheet-like foamed polystyrene, or the like, and is made of a sheet-like material that does not damage the lighting device even if the lighting device comes into contact. The cushioning material 80 has a substantially rectangular edge portion 81, and this edge portion 81 is disposed so as to overlap with the edges 14 b and 14 c of the bottom wall portion 14 of the box portion 11 when viewed from the upper side in the height direction. The When the box part 11 is assembled in a box shape, the edge part end face of the shock absorbing material 80 is pressed inward by the four side wall parts 15 to 18 of the box part 11, and as a result, the shock absorbing material 80 is in the height direction. A vertical direction (hereinafter, this direction is referred to as a horizontal direction) is positioned by the four side wall portions 15 to 18.

緩衝材８０は、厚さ方向に貫通する円形の貫通孔８２を中央部に有し、更に、貫通孔８２から径方向に延在する複数の凹部８３を有する。複数の凹部８３は、貫通孔８２の周方向に間隔をおいて配置され、各凹部８３は、緩衝材８０を厚さ方向に貫通し、略矩形の形状を有する。 The cushioning material 80 has a circular through hole 82 penetrating in the thickness direction at the center, and further has a plurality of recesses 83 extending from the through hole 82 in the radial direction. The plurality of recesses 83 are arranged at intervals in the circumferential direction of the through-hole 82, and each recess 83 penetrates the buffer material 80 in the thickness direction and has a substantially rectangular shape.

緩衝材８０は、図示しない照明装置を箱部１１に対して水平方向に位置決めするために設けられる。詳しくは、先ず、照明装置を、その光照射面を底壁部１４の上面に載置するように箱部１１の中央部に収容する。その後、緩衝材８０を高さ方向上側から底壁部１４側に照明装置に被せるように挿入する。その挿入は、照明装置に緩衝材８０の下面が照明装置のフランジの上面に当接するまで実行される。この挿入の際、照明装置の複数の取付バネは、複数の凹部８３に収容される。緩衝材８０が所定位置まで挿入されると、貫通孔８２の内面が、照明装置の断面円形の外周面に当接する。その結果、照明装置は、緩衝材８０を介して箱部１１の４つの側壁部１５〜１８に対して位置決めされ、箱部１１に対して水平方向に略相対移動不可になる。よって、包装箱１に収納された照明装置が、搬送中等に損傷することを抑制できる。 The cushioning material 80 is provided to position a lighting device (not shown) in the horizontal direction with respect to the box portion 11. Specifically, first, the lighting device is accommodated in the central portion of the box portion 11 so that the light irradiation surface is placed on the upper surface of the bottom wall portion 14. Thereafter, the cushioning material 80 is inserted from the upper side in the height direction so as to cover the lighting device from the bottom wall portion 14 side. The insertion is performed until the lower surface of the cushioning material 80 contacts the upper surface of the flange of the lighting device. During this insertion, the plurality of attachment springs of the lighting device are accommodated in the plurality of recesses 83. When the buffer material 80 is inserted to a predetermined position, the inner surface of the through hole 82 comes into contact with the outer peripheral surface of the lighting device having a circular cross section. As a result, the illuminating device is positioned with respect to the four side wall portions 15 to 18 of the box portion 11 via the cushioning material 80, and cannot be relatively moved relative to the box portion 11 in the horizontal direction. Therefore, it can suppress that the illuminating device accommodated in the packaging box 1 is damaged during conveyance.

箱本体１０が、１枚のシート状の展開状態から箱形状に折り込まれる際、折込部２０は、折目３８で箱の内側に側壁部１５〜１８の内面に対して略４５°をなす方向に折り込まれる。再度、図２を参照して、折込部２０において第１方向延在部３１よりも高さ方向上側に位置するＸ領域（点線で囲まれた領域）は、図１に示す折り込み状態において、略高さ方向の全域にわたって高さ方向に延在する柱部１２を構成する。図１及び図２に示すように、第１接続縁２１の長さａ［ｃｍ］は、柱部１２の高さに一致する。また、図１及び図２を参照して、第２接続縁２２は、高さ方向に関し、折込状態で柱部１２の下端よりも上側に位置し、ｂ［ｃｍ］で示す寸法を有する。 When the box body 10 is folded into a box shape from a single sheet-like unfolded state, the folding part 20 forms a direction of approximately 45 ° with respect to the inner surfaces of the side wall parts 15 to 18 inside the box at the folds 38. Folded into. Referring to FIG. 2 again, the X region (the region surrounded by the dotted line) located in the height direction above the first direction extending portion 31 in the folding portion 20 is substantially in the folded state shown in FIG. A column portion 12 extending in the height direction over the entire height direction is configured. As shown in FIGS. 1 and 2, the length a [cm] of the first connection edge 21 coincides with the height of the column part 12. 1 and 2, the second connection edge 22 is located above the lower end of the column part 12 in the folded state in the height direction, and has a dimension indicated by b [cm].

図２の展開図においては、段ボールのライナー６１の一部を剥いだ状態が図示され、中芯６２の延在方向が示されている。図２に示すように、中芯６２は、Ｘ方向に行くにしたがって波状に変化し、Ｙ方向に直線上に延在する。このことから、段ボールの目方向は、Ｙ方向に一致する。図３を参照して、展開状態で、折込部２０において折目３８を境にしてＹ方向外側に位置するＹ領域は、図１にＹで示す領域に一致する。第２接続縁２２の長さｂは、図１のＹ領域の高さに一致する。ｂは、以上の長さに設定されてもよいが、ａより短ければ好ましく、０.３ａ≦ｂ≦０.７ａを満たすとより好ましく、０.４ａ≦ｂ≦０.６ａを満たすと更に好ましく、０.４５ａ≦ｂ≦０.５５ａを満たすと最も好ましい。本実施例では、ｂは、ａ／２の長さに設定されている。 In the development view of FIG. 2, a state in which a part of the cardboard liner 61 is peeled off is illustrated, and the extending direction of the center core 62 is illustrated. As shown in FIG. 2, the center core 62 changes in a wave shape as it goes in the X direction, and extends linearly in the Y direction. For this reason, the eye direction of the cardboard coincides with the Y direction. Referring to FIG. 3, in the unfolded state, the Y region located on the outer side in the Y direction with the fold 38 as a boundary in the folded portion 20 matches the region indicated by Y in FIG. The length b of the second connection edge 22 corresponds to the height of the Y region in FIG. b may be set to the above length, but is preferably shorter than a, more preferably satisfies 0.3a ≦ b ≦ 0.7a, and more preferably satisfies 0.4a ≦ b ≦ 0.6a. , 0.45a ≦ b ≦ 0.55a is most preferable. In this embodiment, b is set to a / 2 length.

図３に示すように、折込部２０は、折目３８の外側に折目３８の延在方向に対して内側に窪んだ凹部４０を有する。本実施例では、凹部４０は、図２及び図３に示す平面視で略矩形の形状を有し、Ｘ方向に延在する縁と、Ｙ方向に延在する縁を有する。図１に示すように、折込部２０が折り込まれた状態で、折目３８は、高さ方向上側に行くにしたがって箱部内側に移動するように斜めに傾斜する。凹部４０を形成することで、折り込まれた状態で、折込部２０が過度に内側にせり出さないようにして、照明装置が収容されるスペースが過度に小さくならないようにしている。なお、本実施例と異なり、折込部は、折目の外側に折目の延在方向に対して内側に窪んだ凹部を有さなくてもよい。 As shown in FIG. 3, the folding part 20 has a recess 40 that is recessed inward with respect to the extending direction of the fold 38 on the outside of the fold 38. In this embodiment, the recess 40 has a substantially rectangular shape in plan view shown in FIGS. 2 and 3, and has an edge extending in the X direction and an edge extending in the Y direction. As shown in FIG. 1, in a state in which the folding part 20 is folded, the fold 38 is inclined obliquely so as to move to the inside of the box part as it goes upward in the height direction. By forming the recess 40, the folded portion 20 is prevented from protruding excessively inward in a folded state so that the space in which the lighting device is accommodated is not excessively reduced. In addition, unlike a present Example, a folding part does not need to have the recessed part recessed inside with respect to the extension direction of a fold on the outer side of a fold.

再度、図１及び図３を参照して、第１方向延在部３１のＹ方向の幅は、緩衝材８０の厚さよりも長くなっている。詳しくは、第１方向延在部３１のＹ方向の幅は、緩衝材８０の厚さと照明装置のフランジの厚さを足した長さ以上の長さになっている。本実施例では、第１方向延在部３１のＹ方向の幅は、緩衝材８０の厚さと照明装置のフランジの厚さを足した長さに設定されている。 Referring to FIGS. 1 and 3 again, the width in the Y direction of the first direction extending portion 31 is longer than the thickness of the cushioning material 80. Specifically, the width in the Y direction of the first direction extending portion 31 is equal to or longer than the sum of the thickness of the cushioning material 80 and the thickness of the flange of the lighting device. In the present embodiment, the width in the Y direction of the first direction extending portion 31 is set to a length obtained by adding the thickness of the cushioning material 80 and the thickness of the flange of the lighting device.

以上、包装箱１は、折目が形成された一枚のシート状の段ボールを折目に沿って折り込むことで箱形状に形成される箱部１１を含む箱本体１０を備える。また、箱本体１０は、平面視で略矩形の内側面を含む上壁部１９と、Ｘ方向に延在する一対の第１縁部１４ｂ、及びＸ方向に直交するＹ方向に延在する一対の第２縁部１４ｃを含む略矩形の内側面１４ａを有する底壁部１４を備える。また、箱本体１０は、その側壁を構成する４つの側壁部１５〜１８に含まれ、第１縁部１４ｂに接続される一対の第１側壁部１５,１７と、４つの側壁部１５〜１８に含まれ、組立状態で第１側壁部１５,１７と略直交する一対の第２側壁部１６,１８を備える。また、箱本体１０は、シート状に展開した展開状態での平面視において、Ｘ方向から見たとき片方の第１側壁部１５又は１７に重なると共に、Ｙ方向から見たとき片方の第２側壁部１６又は１８に重なる重なり領域に設けられる折込部２０を備える。また、折込部２０は第１側壁部１５,１７において組立状態で高さ方向に延びる第１高さ方向延在縁１５ａ,１７ａに繋がる第１接続縁２１、及び第２側壁部１６,１８において組立状態で第１高さ方向延在縁１５ａ,１７ａに略重なるように配置される第２高さ方向延在縁１６ａ,１８ａに繋がる第２接続縁２２を含む。また、折込部２０には、平面視でＬ字形状を有する切れ目３０が設けられる。また、平面視において、切れ目３０は、底壁部１４側の端から第２接続縁２２まで第２高さ方向延在縁１６ａ,１８ａに沿うようにＸ方向に延在する第１方向延在部３１と、第１方向延在部３１の底壁部１４側とは反対側の端部からＹ方向に延在する第２方向延在部３２を含む。 As described above, the packaging box 1 includes the box body 10 including the box portion 11 that is formed into a box shape by folding a sheet-like cardboard on which a fold is formed along the fold. The box body 10 includes an upper wall portion 19 including a substantially rectangular inner surface in a plan view, a pair of first edge portions 14b extending in the X direction, and a pair extending in the Y direction orthogonal to the X direction. The bottom wall 14 has a substantially rectangular inner surface 14a including the second edge 14c. Moreover, the box main body 10 is included in four side wall parts 15-18 which comprise the side wall, a pair of 1st side wall parts 15 and 17 connected to the 1st edge part 14b, and four side wall parts 15-18. And a pair of second side wall portions 16, 18 that are substantially orthogonal to the first side wall portions 15, 17 in the assembled state. The box body 10 overlaps with the first side wall 15 or 17 on one side when viewed from the X direction when viewed from the X direction, and on the second side wall when viewed from the Y direction. The folding part 20 provided in the overlap area | region which overlaps with the part 16 or 18 is provided. In addition, the folding part 20 is connected to the first connection edge 21 connected to the first height extending edges 15a and 17a extending in the height direction in the assembled state in the first side wall parts 15 and 17, and the second side wall parts 16 and 18. It includes a second connection edge 22 connected to the second height direction extending edges 16a, 18a arranged so as to substantially overlap the first height direction extending edges 15a, 17a in the assembled state. Further, the folding portion 20 is provided with a cut 30 having an L shape in plan view. In plan view, the cut 30 extends in the X direction from the end on the bottom wall portion 14 side to the second connection edge 22 along the second height direction extending edges 16a and 18a. The part 31 and the 2nd direction extension part 32 extended in the Y direction from the edge part on the opposite side to the bottom wall part 14 side of the 1st direction extension part 31 are included.

したがって、展開状態において折込部２０における第１方向延在部３１よりもＹ方向外側に位置するＸ領域で、箱部１１を箱状に形成した際に高さ方向に柱状に延在する柱部１２を構成できる。よって、包装箱１は、柱部１２で高さ方向の圧縮力を受けることができるので、該圧縮力に対する強度が大きくなり、高さ方向の座屈を抑制できる。 Therefore, in the unfolded state, the column portion that extends in a columnar shape in the height direction when the box portion 11 is formed in a box shape in the X region located outside the first direction extension portion 31 in the folded portion 20 in the Y direction. 12 can be configured. Therefore, since the packaging box 1 can receive the compressive force in the height direction at the pillar portion 12, the strength against the compressive force is increased, and buckling in the height direction can be suppressed.

また、第２方向延在部３２は、Ｘ方向の幅を有するスリット形状を有してもよい。 Further, the second direction extending portion 32 may have a slit shape having a width in the X direction.

上記構成によれば、第２方向延在部３２がＸ方向の幅を有する貫通孔形状であるので、Ｙ領域が、折込部２０におけるそれ以外の領域に対して折れ曲がり易くなる。よって、図１に示すように、折込部２０を折り込む際にＹ領域をそれ以外の領域（柱部１２を含む領域）に円滑に重ねることができ、箱を円滑に組み立てできる。 According to the above configuration, since the second direction extending portion 32 has a through-hole shape having a width in the X direction, the Y region is easily bent with respect to other regions in the folding portion 20. Therefore, as shown in FIG. 1, when folding the folding part 20, the Y area can be smoothly overlapped with other areas (areas including the column part 12), and the box can be assembled smoothly.

また、Ｙ方向が、箱本体１０を構成する一枚の段ボールの目方向に一致してもよい。 Further, the Y direction may coincide with the eye direction of one cardboard constituting the box body 10.

上記構成によれば、柱部１２における段ボールの目方向が、組み立て状態で高さ方向に一致する。よって、柱部１２の圧縮力に対する強度を大きくでき、高さ方向の座屈を更に効果的に抑制できる。 According to the said structure, the eye direction of the cardboard in the pillar part 12 corresponds with a height direction in an assembly state. Therefore, the strength against the compressive force of the column portion 12 can be increased, and the buckling in the height direction can be further effectively suppressed.

また、第１接続縁２１の長さａは、第２接続縁２２の長さｂよりも長くてもよい。 Further, the length a of the first connection edge 21 may be longer than the length b of the second connection edge 22.

第１接続縁２１は、段ボールの目方向に沿った方向に折り曲げることになる一方、第２接続縁２２は、段ボールの目方向に直交する方向に折り曲げることになる。よって、第２接続縁２２は、第１接続縁２１よりも折り曲げにくく、組立状態における側壁部１５〜１８に対する柱部１２の傾斜角が、第２接続縁２２の折り曲げ角度に依存し易い。 The first connection edge 21 is bent in a direction along the eye direction of the cardboard, while the second connection edge 22 is bent in a direction perpendicular to the eye direction of the cardboard. Therefore, the second connection edge 22 is less likely to be bent than the first connection edge 21, and the inclination angle of the column part 12 with respect to the side wall parts 15 to 18 in the assembled state is likely to depend on the bending angle of the second connection edge 22.

これに対し、上記構成によれば、第１接続縁２１の長さａが、第２接続縁２２の長さｂよりも長い。したがって、第１接続縁２１の折り曲げにくさを、第２接続縁２２の折り曲げにくさに近づけることができ、第１接続縁２１の折り曲げにくさと、第２接続縁２２の折り曲げにくさとをバランスさせることができる。よって、側壁部１５〜１８に対する柱部１２の傾斜角を４５°に近づけることができるので、包装箱１の圧縮力に対する強度が局所的に大きく変動することを抑制でき、結果として、圧縮力に対する強度を、包装箱１の上面の場所によらず大局的に大きな値にすることができる。 On the other hand, according to the above configuration, the length a of the first connection edge 21 is longer than the length b of the second connection edge 22. Accordingly, the difficulty in bending the first connection edge 21 can be made close to the bending difficulty in the second connection edge 22, and the difficulty in bending the first connection edge 21 and the difficulty in bending the second connection edge 22 are obtained. Can be balanced. Therefore, since the inclination angle of the column part 12 with respect to the side wall parts 15-18 can be approximated to 45 degrees, it can suppress that the intensity | strength with respect to the compressive force of the packaging box 1 fluctuates large locally, As a result, with respect to compressive force The strength can be increased to a large value regardless of the location of the upper surface of the packaging box 1.

また、第１方向延在部３１は、Ｙ方向の幅を有するスリット形状を有してもよい。また、包装箱１は、第１方向延在部３１のＹ方向の幅よりも薄い厚さを有すると共に底壁部１４の上側に配置される緩衝材８０を更に備えてもよい。 Further, the first direction extending portion 31 may have a slit shape having a width in the Y direction. The packaging box 1 may further include a cushioning material 80 that is thinner than the width of the first direction extending portion 31 in the Y direction and is disposed on the upper side of the bottom wall portion 14.

上記構成によれば、組立状態において、照明装置を、緩衝材８０を用いて４つの側壁部１５〜１８に対して位置決めできる。よって、搬送中に照明装置が損傷することを抑制できる。また、緩衝材８０が、第１方向延在部３１のＹ方向の幅よりも薄い厚さを有するので、組立状態において、緩衝材８０を、高さ方向に関して、柱部１２の下面と、底壁部１４の上面との間に配置できる。 According to the above configuration, the lighting device can be positioned with respect to the four side wall portions 15 to 18 using the cushioning material 80 in the assembled state. Therefore, it can suppress that an illuminating device is damaged during conveyance. Further, since the cushioning material 80 has a thickness smaller than the width of the first direction extending portion 31 in the Y direction, the cushioning material 80 in the assembled state is separated from the bottom surface of the pillar portion 12 and the bottom in the height direction. It can arrange | position between the upper surfaces of the wall part 14. FIG.

また、包装箱１は、光出射側の端部にフランジを有する埋込式の照明装置を収納するために用いられてもよい。また、第１方向延在部３１のＹ方向の幅は、緩衝材８０の厚さと上記フランジの厚さを足した長さ以上の長さであってもよい。 Moreover, the packaging box 1 may be used in order to accommodate the embedding type illuminating device which has a flange in the edge part by the side of light emission. In addition, the width in the Y direction of the first direction extending portion 31 may be a length equal to or greater than the sum of the thickness of the cushioning material 80 and the thickness of the flange.

上記構成によれば、緩衝材８０と、緩衝材８０の下側に配置されるフランジを、組立状態において、高さ方向に関して、柱部１２の下面と、底壁部１４の上面との間に配置できる。また、特に、第１方向延在部３１のＹ方向の幅が、緩衝材８０の厚さと上記フランジの厚さを足した長さに一致する長さであると、緩衝材８０及びフランジを、柱部１２の下面と、底壁部１４の上面とで挟持できる。よって、その場合、柱部１２、緩衝材８０、及びフランジで、高さ方向に延在すると共に底壁部１４の内側面（上面）に接触する柱を構築でき、その結果、高さ方向の圧縮力に対する強度を更に大きくすることができる。但し、第１方向延在部のＹ方向の幅は、緩衝材８０の厚さと上記フランジの厚さを足した長さよりも短くてもよく、組み立てた際に形成される柱部を少し上側に歪ませるようにして、緩衝材８０及び照明装置を箱内部に収納してもよい。 According to the above configuration, the cushioning material 80 and the flange disposed on the lower side of the cushioning material 80 are arranged between the lower surface of the column portion 12 and the upper surface of the bottom wall portion 14 in the height direction in the assembled state. Can be placed. In particular, if the width in the Y direction of the first direction extending portion 31 is a length that matches the length of the buffer material 80 plus the thickness of the flange, the buffer material 80 and the flange are It can be sandwiched between the lower surface of the column portion 12 and the upper surface of the bottom wall portion 14. Therefore, in that case, it is possible to construct a pillar that extends in the height direction and contacts the inner side surface (upper surface) of the bottom wall portion 14 with the pillar portion 12, the cushioning material 80, and the flange. The strength against the compressive force can be further increased. However, the width in the Y direction of the extending portion in the first direction may be shorter than the length obtained by adding the thickness of the cushioning material 80 and the thickness of the flange, and the column portion formed at the time of assembly slightly upward. The cushioning material 80 and the lighting device may be housed inside the box so as to be distorted.

なお、本開示は、上記実施形態およびその変形例に限定されるものではなく、本願の特許請求の範囲に記載された事項およびその均等な範囲において種々の改良や変更が可能である。 Note that the present disclosure is not limited to the above-described embodiment and the modifications thereof, and various improvements and modifications can be made within the matters described in the claims of the present application and the equivalent scope thereof.

例えば、上記実施形態では、第１方向延在部３１が、Ｙ方向の幅を有するスリット形状である場合について説明した。しかし、図４、すなわち、変形例の箱本体１１０における図２に対応する平面図に示すように、第１方向延在部１３１は、Ｙ方向の幅を有さない切り込みでもよい。この構成の場合、箱本体１１０を組み立てた際、柱部の下面が底壁部１１４の内側面（上面）に接触することになる。よって、高さ方向に対する圧縮力に対する柱部の強度を大きくできる。この変形例の箱本体１１０は、緩衝材を用いない場合に好適に用いられる。また、第２方向延在部３２が、Ｘ方向の幅を有するスリット形状である場合について説明した。しかし、第２方向延在部は、Ｘ方向の幅を有さない切り込みでもよい。 For example, in the above embodiment, the case where the first direction extending portion 31 has a slit shape having a width in the Y direction has been described. However, as shown in FIG. 4, that is, a plan view corresponding to FIG. 2 in the modified box body 110, the first direction extending portion 131 may be a cut having no width in the Y direction. In the case of this configuration, when the box body 110 is assembled, the lower surface of the column portion comes into contact with the inner surface (upper surface) of the bottom wall portion 114. Therefore, the strength of the column portion against the compressive force in the height direction can be increased. The box body 110 of this modification is suitably used when no cushioning material is used. Moreover, the case where the 2nd direction extension part 32 was the slit shape which has the width | variety of a X direction was demonstrated. However, the second direction extending portion may be a cut having no width in the X direction.

また、箱本体１０が、Ｘ方向に延在する一対の第１縁部１４ｂと、Ｘ方向に直交するＹ方向に延在する一対の第２縁部１４ｃとを含む略矩形の内側面１４ａを有する底壁部１４を備える場合について説明した。そして、箱本体１０が、側壁を構成する４つの側壁部１５〜１８に含まれ、第１縁部１４ｂに接続される一対の第１側壁部１５,１７と、４つの側壁部１５〜１８に含まれ、第２縁部１４ｃに接続される一対の第２側壁部１６,１８を備える場合について説明した。しかし、組み立てられた際、同じ箱形状の箱本体１０を形成できる展開図は、複数考えられ、第１側壁部は、第１縁部に接続されなくてもよく、第１側壁部が、組立状態で第１縁部に略重なる縁部を有する構成でもよい。また、同様に、第２側壁部は、第２縁部に接続されなくてもよく、第２側壁部が、組立状態で第２縁部に略重なる縁部を有する構成でもよい。 Further, the box body 10 includes a substantially rectangular inner side surface 14a including a pair of first edge portions 14b extending in the X direction and a pair of second edge portions 14c extending in the Y direction orthogonal to the X direction. The case where the bottom wall part 14 which has is demonstrated. And the box main body 10 is contained in the four side wall parts 15-18 which comprise a side wall, and a pair of 1st side wall parts 15 and 17 connected to the 1st edge part 14b, and four side wall parts 15-18 The case where a pair of second side wall portions 16 and 18 are included and connected to the second edge portion 14c has been described. However, a plurality of development views that can form the same box-shaped box body 10 when assembled are conceivable, and the first side wall portion may not be connected to the first edge portion, and the first side wall portion may be assembled. The structure which has an edge part which overlaps with a 1st edge part in a state may be sufficient. Similarly, the second side wall portion may not be connected to the second edge portion, and the second side wall portion may have an edge portion that substantially overlaps the second edge portion in the assembled state.

また、箱本体１０の展開状態において、折込部２０が４隅に設けられて、柱部１２が、箱内部の４隅に設けられる場合について説明した。しかし、折込部は、箱本体の展開状態において、３隅、２隅、又は１隅のみに設けられてもよく、柱部は、箱内部の３隅、２隅、又は１隅のみに設けられてもよい。柱部を、箱内部の４隅に設けない場合、少なくとも、底壁部の内側面の対角線の延在方向に対向する２隅に設けると、高さ方向に対する圧縮力に対する強度を大きくできて好ましい。 Moreover, in the unfolded state of the box body 10, the case where the folding parts 20 are provided at the four corners and the column part 12 is provided at the four corners inside the box has been described. However, the folding part may be provided only at the three corners, two corners, or one corner in the unfolded state of the box body, and the column part is provided only at the three corners, two corners, or one corner inside the box. May be. When the pillars are not provided at the four corners inside the box, it is preferable to provide them at least at the two corners facing the extending direction of the diagonal line on the inner surface of the bottom wall part, because the strength against the compressive force in the height direction can be increased. .

また、段ボールの目方向が、Ｙ方向に略一致する場合について説明したが、段ボールの目方向は、Ｘ方向に略一致してもよい。また、包装箱１が、緩衝材８０を備える場合について説明したが、包装箱は、緩衝材を備えなくてもよい。また、包装箱１が、埋込式の照明装置を収納する場合について説明した。しかし、本開示の包装箱は、埋込式の照明装置以外の照明装置を収納してもよく、照明装置以外の如何なる製品の収納のために用いられてもよい。 Moreover, although the case where the eye direction of the cardboard substantially coincides with the Y direction has been described, the eye direction of the cardboard may substantially coincide with the X direction. Moreover, although the case where the packaging box 1 was provided with the shock absorbing material 80 was demonstrated, the packaging box does not need to be provided with the shock absorbing material. Moreover, the case where the packaging box 1 accommodates an embedded illumination device was demonstrated. However, the packaging box of the present disclosure may store a lighting device other than the embedded lighting device, and may be used for storing any product other than the lighting device.
