Description

この考案は、物品を梱包する際、物品の端部に嵌めて、落下等の衝撃から物品を保護する段ボール製緩衝材に関するものである。   The present invention relates to a corrugated cardboard cushioning material that is fitted to an end portion of an article and protects the article from an impact such as dropping when the article is packed.

物品の梱包に際して使用する段ボール製緩衝材として、下記特許文献１には、図５に示すようなものが記載されている。この緩衝材は、底壁５１及び対向する側壁５２を備えた形状とされ、底壁５１の底板５３の両側に内側板５４、頂板５５、外側板５６及び底重板５７が順次連設されている。   As a corrugated cardboard cushioning material used for packing an article, the following Patent Document 1 describes one as shown in FIG. The cushioning material has a shape including a bottom wall 51 and an opposite side wall 52, and an inner plate 54, a top plate 55, an outer plate 56, and a bottom weight plate 57 are sequentially arranged on both sides of the bottom plate 53 of the bottom wall 51. Yes.

この緩衝材の組み立てに際しては、底板５３から内側板５４を起立させ、頂板５５を外側水平方向へ、外側板５６を下方へ順次折り曲げ、底重板５７を底板５３の下面に重ねるように折り曲げて接着し、底板５３の上面に底敷板５８を重ねて接着する。   When assembling the cushioning material, the inner plate 54 is erected from the bottom plate 53, the top plate 55 is bent in the outer horizontal direction, the outer plate 56 is sequentially bent downward, and the bottom heavy plate 57 is folded so as to overlap the lower surface of the bottom plate 53. Bonding is performed, and the bottom plate 58 is stacked on the upper surface of the bottom plate 53 and bonded.

このように組み立てると、底重板５７、底板５３及び底敷板５８から底壁５１が形成され、内側板５４、頂板５５、外側板５６から側壁５２が形成される。   When assembled in this manner, the bottom wall 51 is formed from the bottom weight plate 57, the bottom plate 53, and the bottom plate 58, and the side wall 52 is formed from the inner plate 54, the top plate 55, and the outer plate 56.

そして、対向する側壁５２の内側板５４が底壁５１から離れるに従い間隔が狭くなるように傾斜するので、梱包対象の物品を側壁５２の間に挿入すると、対向する側壁５２に物品が銜え込まれ、物品のがたつきが防止される。   Since the inner plate 54 of the opposing side wall 52 is inclined so that the interval becomes narrower as the distance from the bottom wall 51 increases, when the article to be packed is inserted between the side walls 52, the article is caught in the opposing side wall 52. , Rattling of the article is prevented.

実登第２５８６０７３号公報JITTO No. 2586073

ところで、上記のような緩衝材では、建築用の資材等、重量のある大型物品の端部保護に適用しようとすると、側壁５２の強度が十分でない場合がある。   By the way, in the buffer material as described above, the strength of the side wall 52 may not be sufficient when it is applied to the end protection of a heavy article such as a building material.

そのような場合、段ボールを多層に積層してアングル材やチャンネル材のような形状としたいわゆるコルパッドが使用されるが、コルパッドは重量が大きく、また高コストであるという問題がある。   In such a case, a so-called corpad having a shape such as an angle material or a channel material obtained by laminating corrugated cardboards in multiple layers is used. However, there is a problem that the corpad is heavy and expensive.

そこで、この考案は、梱包対象の物品を確実に銜え込むことができ、かつ、軽量で強度に優れ、低コストで製造できる段ボール製緩衝材を提供することを課題とする。   Accordingly, an object of the present invention is to provide a cardboard cushioning material that can reliably hold an article to be packed, and is lightweight, excellent in strength, and can be manufactured at low cost.

上記のような課題を解決するため、この考案は、底壁の両側に側壁を立設し、対向する側壁の内面を底壁から離れるに従い間隔が狭くなるように傾斜させた段ボール製緩衝材において、前記側壁では、底壁の底板に順次連なる外側板、頂板及び内側板を巻き込むように折り曲げて、外側板と内側板の間に重合部材の中側板を挟み、重合部材の中側板を、底壁側よりも頂板側が内側へ厚くなるように折り重ね、これにより内側板が傾斜するようにしたのである。   In order to solve the above-described problems, the present invention provides a corrugated cardboard cushioning material in which side walls are erected on both sides of the bottom wall and the inner surfaces of the opposing side walls are inclined so that the interval decreases as the distance from the bottom wall increases. In the side wall, the outer plate, the top plate, and the inner plate that are successively connected to the bottom plate of the bottom wall are bent so that the middle plate of the superposed member is sandwiched between the outer plate and the inner plate, and the middle plate of the superposed member is placed on the bottom wall side. The top plate is folded so that the top plate is thicker inward, so that the inner plate is inclined.

また、前記底板、外側板、頂板及び内側板を有する本体部材と重合部材とは別体とし、重合部材は、底板に重なる内底板の両側に中側板を連設した構成としたのである。   In addition, the main body member having the bottom plate, the outer plate, the top plate, and the inner plate is separated from the superposed member, and the superposed member has a configuration in which middle plates are continuously provided on both sides of the inner bottom plate overlapping the bottom plate.

この考案に係る段ボール製緩衝材では、側壁の外側板と内側板の間に、底壁側よりも頂板側が内側へ厚くなるように折り重ねた中側板を挟んで、側壁の内側板を傾斜させていることから、梱包対象の物品が確実に銜え込まれる。このため、梱包作業時における物品からの脱落が防止され、作業性が向上する。   In the cardboard cushioning material according to the present invention, the inner side plate of the side wall is inclined between the outer side plate and the inner side plate with the inner side plate folded so that the top plate side is thicker inward than the bottom wall side. For this reason, the goods to be packed are reliably received. For this reason, dropping from the article during the packing operation is prevented, and workability is improved.

また、重量のある大型物品を梱包した状態で衝撃力が作用しても、内側板の傾斜が維持され、優れた緩衝性を得ることができる。   In addition, even when an impact force is applied in a state where a large article having a heavy weight is packed, the inclination of the inner plate is maintained, and an excellent buffering property can be obtained.

また、コルパッドよりも段ボールの使用量が減少することから、軽量となって取扱性が向上するほか、製造コストも抑制される。   Further, since the amount of corrugated cardboard used is smaller than that of the corpad, the weight is reduced and handling is improved, and the manufacturing cost is also suppressed.

以下、この考案の実施形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

この段ボール製緩衝材は、図１にブランクの状態で示すように、本体部材１０と２枚の重合部材２０，３０とから構成される。   As shown in a blank state in FIG. 1, the cardboard cushioning material is composed of a main body member 10 and two superposed members 20 and 30.

本体部材１０のブランクでは、長方形の底板１１の対向する長辺に外側板１２、頂板１３及び内側板１４がそれぞれ順次連設され、底板１１の一方の短辺に外端板１５、頂板１６及び内端板１７が順次連設されている。また、外側板１２の一方の側端に中端板１８が連設されている。   In the blank of the main body member 10, the outer plate 12, the top plate 13, and the inner plate 14 are sequentially connected to the opposing long sides of the rectangular bottom plate 11, respectively, and the outer end plate 15, the top plate 16, and Inner end plates 17 are successively provided. A middle end plate 18 is connected to one side end of the outer plate 12.

内側板１４の先端中央部には、係合突起１４ａが設けられ、内端板１７の先端中央部には、係合突起１７ａが設けられている。底板１１の外端板１５寄りの部分には、係合穴１１ａが設けられている。   An engagement protrusion 14 a is provided at the center of the front end of the inner plate 14, and an engagement protrusion 17 a is provided at the center of the front end of the inner end plate 17. An engagement hole 11 a is provided in a portion of the bottom plate 11 near the outer end plate 15.

重合部材２０のブランクでは、長方形の内底板２１の対向する長辺に中側板２２，２３がそれぞれ順次連設され、これらの境界の折目線は、段ボールを折り曲げの内側となるライナーを残して厚さ方向に切り込んだ半切線とされている。内底板２１の中側板２２との境界沿いの中央部には、係合穴２１ａが設けられている。   In the blank of the overlapping member 20, the inner side plates 22 and 23 are successively connected to the opposing long sides of the rectangular inner bottom plate 21, respectively, and the crease lines at these boundaries are thicker leaving the liner that is the inner side of folding the cardboard. It is a half-cut line cut in the vertical direction. An engagement hole 21 a is provided in the central portion along the boundary with the inner side plate 22 of the inner bottom plate 21.

中側板２２，２３の連設方向において、中側板２３の寸法は、中側板２２の寸法の半分よりも小さくなっている。   In the connecting direction of the middle side plates 22 and 23, the dimension of the middle side plate 23 is smaller than half of the dimension of the middle side plate 22.

重合部材３０のブランクでは、長方形の中底板３１の対向する長辺に中側板３２がそれぞれ連設され、中底板３１の中側板３２との境界沿いの中央部には、係合穴３１ａが設けられている。   In the blank of the overlapping member 30, the middle side plate 32 is continuously provided on the long side of the rectangular middle bottom plate 31 facing each other, and the engagement hole 31 a is provided at the center along the boundary with the middle side plate 32 of the middle bottom plate 31. It has been.

また、段ボールの厚さを考慮して、本体部材１０と２枚の重合部材２０，３０のブランクでは、底板１１、中底板３１及び内底板２１と外側板１２、中側板３２及び中側板２２の連設方向の寸法が順次小さくなるように設定されている。   Further, in consideration of the thickness of the corrugated cardboard, in the blank of the main body member 10 and the two overlapping members 20, 30, the bottom plate 11, the middle bottom plate 31, the inner bottom plate 21 and the outer plate 12, the middle side plate 32, and the middle side plate 22 The dimensions in the continuous direction are set so as to decrease sequentially.

上記のようなブランクから緩衝材を組み立てる際には、図２に示すように、底板１１の上面に中底板３１及び内底板２１を順次重ねて底壁１を形成し、中側板２２を起立させ、中側板２３を内側下方へ折り曲げて中側板２２の内面に重ね、中側板３２を起立させて中側板２２の外面に重ねる。   When assembling the cushioning material from the blank as described above, as shown in FIG. 2, the bottom wall 1 is formed by sequentially stacking the middle bottom plate 31 and the inner bottom plate 21 on the upper surface of the bottom plate 11, and the middle side plate 22 is raised. Then, the inner side plate 23 is folded inwardly and overlapped on the inner surface of the inner side plate 22, and the inner side plate 32 is raised and overlapped on the outer surface of the inner side plate 22.

次に、外側板１２を起立させ、中端板１８を内側へ折り曲げて重ね合わせ、図３に示すように、外端板１５、頂板１６及び内端板１７を巻き込むように折り曲げて、外端板１５と内端板１７の間に中端板１８を挟み込み、係合突起１７ａを係合穴１１ａに係合させて内端板１７の反発を抑制し、底壁１の一端に立ち上がる端壁３を形成する。   Next, the outer side plate 12 is erected, the middle end plate 18 is folded inward and overlapped, and as shown in FIG. 3, the outer end plate 15, the top plate 16 and the inner end plate 17 are folded so as to be wound. An end wall that sandwiches the middle end plate 18 between the plate 15 and the inner end plate 17, engages the engagement protrusion 17 a with the engagement hole 11 a, suppresses repulsion of the inner end plate 17, and rises at one end of the bottom wall 1. 3 is formed.

その後、図３及び図４に示すように、頂板１３を内側水平方向へ、内側板１４を斜め外側下方へ順次折り曲げて、外側板１２と内側板１４の間に中側板２２，２３、３２を挟み込み、係合突起１４ａを係合穴２１ａ，３１ａに係合させて内側板１４の反発を抑制し、底壁１の両側に立ち上がる側壁２を形成する。   Thereafter, as shown in FIGS. 3 and 4, the top plate 13 is bent in the inner horizontal direction and the inner plate 14 is sequentially bent obliquely outward and downward, so that the inner plates 22, 23, 32 are interposed between the outer plate 12 and the inner plate 14. The side wall 2 that rises on both sides of the bottom wall 1 is formed by sandwiching and engaging the engagement protrusions 14 a with the engagement holes 21 a and 31 a to suppress the repulsion of the inner plate 14.

このように組み立てた段ボール製緩衝材を使用して、例えば、建物の窓枠を梱包する際には、窓枠のコーナー部に緩衝材を嵌合させ、ポリプロピレン製のバンドを掛け回して、窓枠と緩衝材とを固定する。   For example, when packing a window frame of a building using a corrugated cardboard cushioning material assembled in this way, the cushioning material is fitted to the corner portion of the window frame, and a polypropylene band is wound around the window frame. Fix the frame and cushioning material.

上記梱包に際し、この緩衝材では、側壁２の外側板１２と内側板１４の間に、底壁１側よりも頂板１３側が内側へ厚くなるように折り重ねた中側板２２，２３を挟んで、側壁２の内側板１４を傾斜させていることから、窓枠が確実に銜え込まれて、バンド掛けするまでの間における窓枠からの脱落が防止され、作業効率の低下が防止される。   At the time of packing, in this cushioning material, sandwiched between the outer side plate 12 and the inner side plate 14 of the side wall 2 are the inner side plates 22 and 23 folded so that the top plate 13 side is thicker inward than the bottom wall 1 side, Since the inner side plate 14 of the side wall 2 is inclined, the window frame is securely gripped and is prevented from falling off from the window frame until it is banded, thereby preventing a reduction in work efficiency.

また、物流過程の荷扱い作業において、重量のある大型の窓枠を梱包した状態で衝撃力が作用しても、内側板１４の傾斜が維持され、優れた緩衝性を得ることができる。   Further, even when an impact force is applied in the state of packing a heavy and large window frame in the load handling operation in the physical distribution process, the inclination of the inner plate 14 is maintained, and excellent buffering properties can be obtained.

また、コルパッドよりも段ボールの使用量が減少することから、軽量となって取扱性が向上するほか、製造コストも抑制される。   Further, since the amount of corrugated cardboard used is smaller than that of the corpad, the weight is reduced and handling is improved, and the manufacturing cost is also suppressed.

なお、上記実施形態では、窓枠のコーナー部に嵌めるため、端壁３を有するものを例示したが、窓枠の上下枠や側枠の中間部に嵌めるもの等については、端壁３のないチャンネル材とすればよい。   In addition, in the said embodiment, in order to fit in the corner part of a window frame, what has the end wall 3 was illustrated, but there is no end wall 3 about what fits in the upper and lower frame of a window frame, the intermediate part of a side frame, etc. Channel material can be used.

また、重合部材３０を備えたものを例示したが、梱包対象の物品の重量等の条件によっては、重合部材３０を省略してもよい。   Moreover, although the thing provided with the superposition | polymerization member 30 was illustrated, depending on conditions, such as the weight of the articles | goods to be packed, the superposition | polymerization member 30 may be abbreviate | omitted.

また、本体部材１０と重合部材２０とが別体となり、重合部材２０に内底板２１を備えたものを例示したが、重合部材２０が中側板２２，２３のみから成るものとして、中側板２２，２３を内側板１４に順次連設してもよい。   Moreover, although the main body member 10 and the superposition | polymerization member 20 became a different body and illustrated what equipped the superposition | polymerization member 20 with the inner bottom board 21, although the superposition | polymerization member 20 consists only of the inner side boards 22 and 23, 23 may be sequentially connected to the inner plate 14.
