Description

【０００１】
【発明の属する技術分野】
本発明は、包装箱と収納物品との間に配置される緩衝体に関する。
【０００２】
【従来の技術】
従来、包装箱内の収納物品を衝撃から保護するために、発泡スチロールに替えて、段ボール板紙を折り曲げて組立て、包装箱と収納物品との間に配置した緩衝体が知られている（例えば、特許文献１参照。）。
【０００３】
該緩衝体は、矩形状の底板と、底板の両長辺側縁にそれぞれ連設された一対の第１側板と、底板の両短辺側縁に連設された一対の第２側板と、両第２側板の先端縁に上縁板を介して連設された一対の内側板とからなる。両内側板は、底板よりも幅広に形成されている。両第１側板の両側縁部には、一対の第１スリットが形成されている。また、両内側板の両側縁部には、一対の第２スリットが形成されている。
【０００４】
該緩衝体は、第１・第２側板を垂直に起立し、上縁板を介して内側板を内側へ折返し、両第１スリットと両第２スリットとを係合させることにより組み立てられる。両内側板の両側縁は、包装箱の側壁に接触している。また、両内側板は底板よりも幅広に形成されているため、第１側板は包装箱の側壁から間隔を存して起立している。また、上縁板により第２側板と内側板とは間隔を存して起立している。収納物品は、両第１側板と両内側板とで囲まれた空間に収納される。
【０００５】
このような段ボール板紙を折り曲げて組立てた緩衝体は、発泡スチロールの緩衝体と比較して、焼却処理する場合に焼却炉を傷めないというメリットがある。しかしながら、その反面、従来の段ボール板紙の緩衝体は、組立てる工程が多く、手数がかかるという問題がある。

【０００７】
【発明が解決しようとする課題】
本発明は上記背景を鑑みてなされたものであり、製造容易で、且つ組立て工程が少ない緩衝体を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記目的を達成するため、本発明の緩衝体は、包装箱に挿入される緩衝体において、該包装箱の底壁と略同形状の底板を備え、該底板の側縁には、底板の側縁から突出する第１突片が設けられ、該第１突片は、切込部により底板の内側まで延設され、包装箱に挿入して底板と底壁とを重ね合わせたとき、該第１突片は、第１突片の一部が包装箱の側壁に接触することにより斜め上方に起立する。
【０００９】
かかる発明によれば、第１突片は、包装箱へ緩衝体を挿入する際に包装箱の側壁に接触し自動的に斜め上方に起立するため、第１突片を斜め上方に折り曲げてから包装箱に挿入する組み立て工程を省くことができる。また、第１突片は、収納物品と接触することにより、包装箱の内での収納物品の横移動を防止する。さらに、第１突片は、斜め上方に起立しているため、包装箱の側壁と収納物品との間に空間が発生し、包装箱外部からの収納物品への衝撃を緩和する。
【００１０】
また、前記第１突片は、前記底板の側縁から略垂直に延びる第１辺と、該第１辺の外端から該底板の側縁に略並行に延びる第２辺と、該第２辺の端から該底板の側縁に向かって斜めに延びる第３辺とを備え、前記切込部は、前記第１辺の延長上に前記底板の内側へ延設された切込線であって、該底板には、該切込線の内端から前記第３辺の内端に向かって斜めに延びる折目線が形成され、該第１突片は、折目線を介して斜め上方に起立する。
【００１１】
また、本発明の緩衝体は、包装箱に挿入される緩衝体において、該包装箱の底壁と略同形状の底板を備え、該底板の側縁には、底板の側縁から突出する第２突片が設けられ、該第２突片は、一対の切込線により底板の内側まで延設され、包装箱に挿入して底板と底壁とを重ね合わせたとき、該第２突片は、包装箱の側壁に接触することにより斜め上方に起立し、そして、前記包装箱に収納する収納物品に押圧され、前後方向の断面が略Ｌ字状に折れ曲がり、該第２突片の先端部が前記側板と収納物品との間に挟まれて配置されることを特徴とする。
【００１２】
かかる発明によれば、第２突片は、包装箱へ緩衝体を挿入する際に包装箱の側壁に接触し自動的に上方へ斜めに起立するため、第２突片を折り曲げてから包装箱に挿入する組み立て工程を省くことができる。また、第２突片は、収納物品が収納されて初めて前後方向の断面略Ｌ字状に形成される。このため、第２突片を、収納物品が収納される前から断面略Ｌ字状に形成している場合のように、収納物品に押圧されて第２突片が２つに折り重なって緩衝体として機能しないことはない。さらに、第２突片の先端は、包装箱の側壁と収納物品の間に配置されるため、包装箱外部からの収納物品への衝撃を緩和する。
【００１３】

【００２２】
次に、本実施形態の緩衝体１の組み立て工程を説明する。
【００２３】
図３に示すように、緩衝体１を折目線ｅ，ｏを介して第１・第２側板８，１９を上方へ折り曲げ、一点鎖線で示した包装箱２の中へ収納する。このとき、第１突片５と、第２突片７とが包装箱２の側壁に接触し自動的に斜め上方へ起立する。底板４は、包装箱２の底壁と略同形状であるため、包装箱２内で横移動することはない。
【００２４】
次いで、図４に示すように、反射鏡３ｂを緩衝体１内に挿入する。このとき、第２突片７は、図５に示すように、反射鏡３ｂに押圧されて断面略Ｌ字状に折れ曲がる。これにより、図６に示すように、反射鏡３ｂを挿入する前から、略Ｌ字状に形成するとことにより、第２突片７が折返されることを防止することができる。また、図４に示すように、第１突片５は反射鏡３ｂの底部と接触しており、反射鏡３ｂの左方向への横ずれを防止する。
【００２５】
次いで、第1天板１２を折目線ｇを介して内側へ折り曲げる。このとき、切込線ｌにより形成された片１５は、反射鏡３ｂの突起部（図省略）に接触してやや斜め上方に起立する。また、挿入孔１６、および窓部１８には、反射鏡３ｂの突起部２３ａ〜ｃがそれぞれ挿入される。また、片１３を折目線ｉを介して下方に折り曲げる。このとき、折目線ｉと一対の切込線ｈと支持片１４とに囲まれて支持孔２４が形成される。そして、光源筒３ａは、支持孔２４に挿入して開口部を支持片１４に支持される。次いで、支持片１４の先端部を折目線ｋを介して内側へ折り曲げる。また、図7に示すように、突片９ｂは、包装箱２の側壁に接触している。また、舌片１１は、折目線ｆを介して内側へ折り曲げられ、反射鏡３ｂに設けられた脚部材２３ｄを係止する。
【００２６】
次いで、図4に示すように、係合片２２を折目線ｔを介して内側へ垂直に折り曲げる。そして、第２天板２０を、図１に示すように、折目線ｑを介して内側へ折り曲げる。このとき、係合片２２を係合孔１７を挿入して係合する。また、突片９ｃは、図7に示すように、包装箱２の側壁に接触する。
【００２７】
本実施形態の緩衝体１によれば、第１・第２突片が包装箱２へ緩衝体１を挿入する際に包装箱２の側壁に接触し自動的に斜め上方に起立する。このため、第１・第２突片５，７を斜め上方に折り曲げてから包装箱に挿入する組み立て工程を省くことができる。また、第１突片５は、反射鏡３ｂの底部と接触することにより、包装箱２の内での反射鏡３ｂの横移動を防止する。さらに、第１突片５は、斜め上方に起立しているため、包装箱２の側壁と反射鏡３ｂとの間に空間が発生し、包装箱２の外部からの反射鏡３ｂへの衝撃を緩和する。
【００２８】
また、第２突片７は、反射鏡３ｂに押圧されることにより初めて断面Ｌ字状に形成される。このため、第２突片が反射鏡３ｂが収納される前から断面略Ｌ字状に形成している場合のように、反射鏡３ｂに押圧されて第２突片が２つに折り重なって第２突片が緩衝体として機能しないことはない。さらに、第２突片７の先端は、包装箱２の側壁と反射鏡３ｂとの間に配置されるため、包装箱２の外部からの反射鏡３ｂへの衝撃を緩和する。製造容易で、且つ組立作業が容易である緩衝体１を提供することができる。また、１枚の段ボール板紙で構成されているため、少ない紙面で有効に緩衝体１を構成することができる

BACKGROUND OF THE INVENTION
The present invention relates to a shock absorber disposed between a packaging box and a stored article.
[0002]
[Prior art]
Conventionally, in order to protect the stored articles in the packaging box from impact, a cushioning body is known which is assembled by folding corrugated paperboard instead of foamed polystyrene (for example, patent) Reference 1).
[0003]
The shock absorber includes a rectangular bottom plate, a pair of first side plates connected to both long side edges of the bottom plate, a pair of second side plates connected to both short side edges of the bottom plate, It consists of a pair of inner side board connected with the front-end edge of both 2nd side board via the upper edge board. Both inner side plates are formed wider than the bottom plate. A pair of first slits are formed at both side edges of both first side plates. A pair of second slits are formed at both side edges of both inner plates.
[0004]
The buffer body is assembled by raising the first and second side plates vertically, folding the inner plate inward through the upper edge plate, and engaging both the first slit and the second slit. Both side edges of both inner plates are in contact with the side walls of the packaging box. Moreover, since both the inner side plates are formed wider than the bottom plate, the first side plate stands with a space from the side wall of the packaging box. Further, the second side plate and the inner side plate stand up with an interval by the upper edge plate. The stored article is stored in a space surrounded by both first side plates and both inner plates.
[0005]
The shock absorber assembled by folding the corrugated paperboard has an advantage that the incinerator is not damaged when incineration is performed, compared with the shock absorber of the foamed polystyrene. However, on the other hand, the conventional corrugated paperboard cushion has a problem in that it takes many steps to assemble and is troublesome.

According to this invention, since the first projecting piece comes into contact with the side wall of the packaging box when the cushioning body is inserted into the packaging box and automatically rises obliquely upward, the first projecting piece is bent obliquely upward. The assembly process inserted into the packaging box can be omitted. Moreover, a 1st protrusion piece prevents the lateral movement of the stored article within a packaging box by contacting with a stored article. Furthermore, since the 1st protrusion piece has stood up diagonally upward, a space generate | occur | produces between the side wall of a packaging box, and a storage article, and the impact to the storage article from the packaging box exterior is relieve | moderated.
[0010]
The first projecting piece includes a first side extending substantially vertically from a side edge of the bottom plate, a second side extending substantially parallel to the side edge of the bottom plate from the outer end of the first side, and the second side. A third side extending obliquely from the end of the side toward the side edge of the bottom plate, and the cut portion is a cut line extending inward of the bottom plate on the extension of the first side. The bottom plate is formed with a fold line extending obliquely from the inner end of the cut line toward the inner end of the third side, and the first projecting piece stands obliquely upward via the fold line. To do.
[0011]
The shock absorber of the present invention is a shock absorber inserted into a packaging box, and includes a bottom plate having substantially the same shape as the bottom wall of the packaging box, and a side edge of the bottom plate protrudes from a side edge of the bottom plate. Two projecting pieces are provided, and the second projecting piece is extended to the inside of the bottom plate by a pair of cut lines, and is inserted into the packaging box and the second projecting piece is overlapped with the bottom plate and the bottom wall. Stands up diagonally by contacting the side wall of the packaging box, and is pressed by the storage article stored in the packaging box, and the front-rear direction cross-section is bent into a substantially L shape, and the tip of the second projecting piece The portion is arranged so as to be sandwiched between the side plate and the stored article.
[0012]
According to this invention, the second projecting piece comes into contact with the side wall of the packaging box when the buffer body is inserted into the packaging box and automatically rises obliquely upward. It is possible to omit the assembly process to be inserted into the. Further, the second projecting piece is formed in a substantially L-shaped cross section in the front-rear direction only after the stored article is stored. For this reason, like the case where the 2nd protrusion is formed in cross-sectional substantially L shape before the storage article is accommodated, the 2nd protrusion piece is folded in two by being pressed by the storage article, and the shock absorber Will not function as. Furthermore, since the tip of the second protruding piece is disposed between the side wall of the packaging box and the stored article, the impact on the stored article from the outside of the packaging box is reduced.
[0013]

Next, as shown in FIG. 4, the reflecting mirror 3 b is inserted into the buffer 1. At this time, as shown in FIG. 5, the second projecting piece 7 is pressed by the reflecting mirror 3b and bent into a substantially L-shaped cross section. As a result, as shown in FIG. 6, it is possible to prevent the second projecting piece 7 from being folded back by forming it in a substantially L shape before inserting the reflecting mirror 3b. Further, as shown in FIG. 4, the first projecting piece 5 is in contact with the bottom of the reflecting mirror 3b, and prevents a lateral shift of the reflecting mirror 3b in the left direction.

Next, the first top plate 12 is bent inward through the crease line g. At this time, the piece 15 formed by the cut line l comes up slightly obliquely in contact with the protrusion (not shown) of the reflecting mirror 3b. Further, the projections 23a to 23c of the reflecting mirror 3b are inserted into the insertion hole 16 and the window 18, respectively. Further, the piece 13 is bent downward through the crease line i. At this time, the support hole 24 is formed surrounded by the crease line i, the pair of cut lines h, and the support piece 14. The light source tube 3 a is inserted into the support hole 24 and the opening is supported by the support piece 14. Next, the front end portion of the support piece 14 is bent inward via the crease line k. Further, as shown in FIG. 7, the protruding piece 9 b is in contact with the side wall of the packaging box 2. Further, the tongue piece 11 is bent inward via the crease line f, and locks the leg member 23d provided on the reflecting mirror 3b.
[0026]
Next, as shown in FIG. 4, the engagement piece 22 is bent vertically inward via the crease line t. And the 2nd top plate 20 is bend | folded inside through the crease line q, as shown in FIG. At this time, the engagement piece 22 is engaged by inserting the engagement hole 17. Further, the projecting piece 9c comes into contact with the side wall of the packaging box 2 as shown in FIG.
[0027]
According to the shock absorber 1 of the present embodiment, when the first and second protrusions insert the shock absorber 1 into the packaging box 2, the first and second protruding pieces come into contact with the side wall of the packaging box 2 and automatically stand up obliquely upward. For this reason, the assembly process of bending the first and second projecting pieces 5 and 7 obliquely upward and inserting them into the packaging box can be omitted. Moreover, the 1st protrusion piece 5 prevents the horizontal movement of the reflective mirror 3b within the packaging box 2 by contacting the bottom part of the reflective mirror 3b. Further, since the first projecting piece 5 stands obliquely upward, a space is generated between the side wall of the packaging box 2 and the reflecting mirror 3b, and an impact from the outside of the packaging box 2 to the reflecting mirror 3b is generated. ease.
[0028]
Further, the second projecting piece 7 is formed in an L-shaped cross section only when pressed by the reflecting mirror 3b. For this reason, like the case where the second protrusion is formed in a substantially L-shaped cross section before the reflecting mirror 3b is housed, the second protruding piece is folded into two by being pressed by the reflecting mirror 3b. The two projecting pieces do not function as a shock absorber. Furthermore, since the tip of the second projecting piece 7 is disposed between the side wall of the packaging box 2 and the reflecting mirror 3b, the impact on the reflecting mirror 3b from the outside of the packaging box 2 is reduced. The shock absorber 1 that is easy to manufacture and easy to assemble can be provided. Moreover, since it is composed of a single sheet of corrugated paperboard, the cushioning body 1 can be effectively constructed with a small amount of paper.
