Description

本考案は、段ボール棺に関するもので、詳しくは、強化段ボール板の展開シートを折り曲げて組み立てる簡易組立式の段ボール棺に関するものである。 The present invention relates to a corrugated cardboard cage, and more particularly, to a simple assembly type corrugated cardboard cage that folds and assembles a development sheet of a reinforced corrugated board.

従来より、木製棺に代わる棺として段ボール棺が知られている。段ボール棺は、木製棺に比べ軽量で燃焼性に優れ、段ボール板の折り曲げ加工により簡単に組み立てることができるため、環境に優しい葬送品として注目されている。 Conventionally, a corrugated cardboard basket is known as an alternative to a wooden basket. Corrugated cardboard boxes are attracting attention as environmentally friendly funerals because they are lighter and more combustible than wooden boxes, and can be easily assembled by folding the cardboard board.

最近では、段ボール棺の材料として、特殊な樹脂等を含浸させた多層構造の強化段ボール板が採用され始めている。そして、このような強化段ボール板にＶ溝加工を施して展開シートを作製し、このＶ溝に沿って展開シートを折り曲げるようにした段ボール棺が提案されている。 Recently, a reinforced corrugated board having a multilayer structure impregnated with a special resin or the like has begun to be adopted as a material for the corrugated board bag. Then, a corrugated cardboard cage has been proposed in which a developed sheet is produced by subjecting such a reinforced corrugated board to V-groove processing, and the developed sheet is bent along the V-groove.

例えば図１４および図１５に示すように、従来の段ボール棺１は、棺本体２と蓋３とが強化段ボール板により形成される。これらのうち棺本体２は、強化段ボール板からなる展開シートＰ0（図１５参照）を箱状に折り曲げて組み立てる。 For example, as shown in FIGS. 14 and 15, a conventional corrugated cardboard basket 1 is formed of a corrugated body 2 and a lid 3 by a reinforced corrugated board. Of these, the bag body 2 is assembled by folding a development sheet P0 (see FIG. 15) made of a reinforced corrugated board into a box shape.

図１５に示すように、展開シートＰ0は、矩形の底板２Ａの左右に側板２Ｂ，２Ｂが設けられ、底板２Ａの前後に妻板２Ｃ，２Ｃが設けられる。底板２Ａの各辺には、側板２Ｂおよび妻板２Ｃとの境界に沿って縦Ｖ溝ｙ0、横Ｖ溝ｘ0がほぼ９０゜角でＶ字状にカットされる。図１５の状態から底板２Ａに対し側板２Ｂと妻板２Ｃを縦Ｖ溝ｙ0、横Ｖ溝ｘ0でほぼ垂直に折り曲げ、これらのＶ溝面を接着剤、接着テープ等で固定して図１４に示す棺本体２を完成させる。
なお、側板２Ｂおよび妻板２Ｃの先端でＷ溝（ほぼ９０゜角にカットされたＶ溝を２列に並設して形成した溝）に沿って折り返される枠板２Ｄは、棺本体２の開口部を補強するためのものである。 As shown in FIG. 15, the development sheet P0 is provided with side plates 2B, 2B on the left and right sides of the rectangular bottom plate 2A, and with end plates 2C, 2C before and after the bottom plate 2A. On each side of the bottom plate 2A, a vertical V-groove y0 and a horizontal V-groove x0 are cut into a V shape at an approximately 90 ° angle along the boundary between the side plate 2B and the end plate 2C. From the state shown in FIG. 15, the side plate 2B and the end plate 2C are bent substantially vertically by the vertical V groove y0 and the horizontal V groove x0 with respect to the bottom plate 2A, and these V groove surfaces are fixed with an adhesive, an adhesive tape, etc. The main body 2 is completed.
The frame plate 2D folded back along the W grooves (grooves formed by arranging the V grooves cut at approximately 90 ° in parallel) at the tips of the side plate 2B and the end plate 2C is an opening of the bag body 2 It is for reinforcing the part.

その他、段ボール棺の先行技術としては、特許文献１および２が開示されている。 In addition, Patent Documents 1 and 2 are disclosed as prior art of corrugated cardboard baskets.

特開２０００−４２０６４号公報JP 2000-42064 A 特開２００５−１８７０４９号公報JP 2005-187049 A

しかしながら、上記のような従来の段ボール棺では、棺本体２を組み立てる場合、側板２Ｂと妻板２Ｃとの固定強度を十分に確保しにくい。すなわち、側板２Ｂおよび妻板２ＣのＶ溝面同士の接触面積が小さく、これらの板の起立姿勢が倒れやすいため、側板２Ｂと妻板２Ｃとの固定強度を十分に高めることができないという問題がある。 However, in the conventional corrugated cardboard cage as described above, it is difficult to sufficiently secure the fixing strength between the side plate 2B and the end plate 2C when the cage body 2 is assembled. That is, since the contact area between the V-groove surfaces of the side plate 2B and the end plate 2C is small and the standing posture of these plates tends to collapse, there is a problem that the fixing strength between the side plate 2B and the end plate 2C cannot be sufficiently increased.

これに対し、特許文献１および２に開示されるように、板同士の連結部分に凹溝やフックを設けて固定強度を高める技術も知られているが、これらの段ボール棺では、展開シートから妻板が分離して形成されるため、部品点数が増えて段ボール棺の製造および組立の作業が煩雑になる。特に、妻板部品を展開シート側に後付けする場合、妻板の向きや固定位置がズレて寸法精度が低下しやすい。 On the other hand, as disclosed in Patent Documents 1 and 2, there is also known a technique for increasing the fixing strength by providing concave grooves and hooks in the connecting portion between the plates. Since the end plates are formed separately, the number of parts increases, and the manufacturing and assembling work of the corrugated board is complicated. In particular, when the end plate part is retrofitted to the development sheet side, the direction and the fixing position of the end plate are displaced, and the dimensional accuracy is likely to be lowered.

本考案は、このような現状に鑑みなされたもので、展開シートの組立時における側板と妻板との固定強度を高めるとともに、単一の展開シートに底板、側板および妻板を形成して製造および組立の作業を精度よく簡単に行えるようにした組立式段ボール棺を提供することを目的としている。 The present invention has been made in view of such a situation, and enhances the fixing strength between the side plate and the side plate at the time of assembling the development sheet, and forms and forms the bottom plate, the side plate and the side plate on the single development sheet. An object of the present invention is to provide an assembly type corrugated cardboard cage which can perform the above-mentioned work accurately and easily.

［第１考案］
前記課題を解決するための第１考案の組立式段ボール棺は、
強化段ボール板からなる展開シートの縦横方向にＶ溝を形成し、このＶ溝に沿って展開シートを箱状に折り曲げて組み立てる段ボール棺であって、
矩形の底板と、
この底板の左右で縦Ｖ溝によりほぼ垂直に折り曲げられる矩形の側板と、
前記底板の前後で横Ｖ溝によりほぼ垂直に折り曲げられる矩形の妻板とを備え、
前記側板には、前記妻板よりも前記展開シートの板厚分だけ前記底板の前後方向中央側にズレた位置で、横Ｖ溝によりほぼ垂直内向きに折り曲げられて前記妻板の内側に重なる挟み代板が設けられ、
前記妻板には、前記挟み代板の上方で横Ｖ溝によりほぼ水平内向きに折り曲げられる架橋板と、この架橋板の先端から横Ｖ溝によりほぼ垂直下向きに折り曲げられて前記挟み代板の内側に重なる折返し板とが設けられる構成とした。 [First Device]
Assembling type corrugated cardboard cage of the 1st device for solving the above-mentioned subject is,
A corrugated cardboard box which is formed by forming V-grooves in the longitudinal and lateral directions of a development sheet made of reinforced corrugated board and folding the development sheet into a box shape along the V-grooves,
A rectangular bottom plate;
A rectangular side plate that is bent substantially vertically by a vertical V-groove on the left and right of the bottom plate;
A rectangular twill plate that is bent substantially vertically by a lateral V-groove before and after the bottom plate,
The side plate has a pinch margin that is bent substantially vertically inward by a lateral V-groove and overlaps the inside of the end plate at a position shifted to the center side in the front-rear direction of the bottom plate by the thickness of the spread sheet from the end plate. A board is provided,
On the end plate, a bridging plate that is bent substantially horizontally inward by a lateral V-groove above the pinch plate, and an inner side of the pinch plate that is bent substantially vertically downward by a horizontal V-groove from the tip of the bridging plate. And a folded plate that overlaps with each other.

本考案の段ボール棺を組み立てる場合、例えばまず、底板の左右で縦Ｖ溝に沿って側板を垂直に折り曲げ、さらに、この側板の前後で挟み代板を垂直内向きに折り曲げる。次いで、この挟み代板を抱き込むように、妻板、架橋板および折返し板を横Ｖ溝に沿ってそれぞれほぼ９０゜角に折り曲げて挟み代板の外側と内側にそれぞれ妻板と折返し板を重ねる。 When assembling the corrugated board cage of the present invention, for example, first, the side plate is bent vertically along the vertical V-grooves on the left and right sides of the bottom plate, and further, the sandwiching plate is bent vertically inward before and after the side plate. Next, the end plate, the bridging plate and the folded plate are folded at about 90 ° along the lateral V-groove so as to embrace the sandwiching plate, and the end plate and the folded plate are overlapped on the outside and inside of the sandwiched plate, respectively.

このような構成によれば、挟み代板の外側と内側にそれぞれ妻板と折返し板を重ねることで、これらの板面に広い範囲で接触面を確保することができる。これにより、側板と妻板との固定強度を高めて段ボール棺の耐荷重性を向上させることができる。
なお、段ボール棺の固定手段としては、接着剤、接着テープ等を用いることが望ましいが、本発明の構成では、組み立て後に折返し板が段ボール棺の内部で上方に跳ね上がらないようにすれば、必ずしも上記固定手段を用いなくともよい。例えば、折返し板の幅を底板の幅とほぼ等しくして、互いに向き合う側板の間に押し込むようにするか、段ボール棺の内部に落とし蓋のように内底板を落とし込んで折返し板の先端を止めることで、折返し板の上方への跳ね上がりを防止してもよい。 According to such a structure, a contact surface can be ensured in a wide range on these plate surfaces by overlapping the end plate and the folded plate on the outer side and the inner side of the sandwiching plate, respectively. Thereby, the fixed strength of the side plate and the end plate can be increased, and the load resistance of the corrugated board can be improved.
In addition, it is desirable to use an adhesive, an adhesive tape, or the like as a means for fixing the corrugated cardboard basket. However, in the configuration of the present invention, if the folded plate is prevented from jumping up inside the corrugated cardboard basket after assembly, it is not always necessary. The fixing means may not be used. For example, by making the width of the folded plate approximately equal to the width of the bottom plate and pushing it between the side plates facing each other, or dropping the inner bottom plate into the inside of the cardboard box like a lid and stopping the tip of the folded plate Further, the upward folding of the folded plate may be prevented.

また、第１考案の構成によれば、底板、側板および妻板に加えて挟み代板、架橋板および折返し板を単一の展開シート（ワンシート）で形成することができるため、低コストで効率よく段ボール棺を製造することが可能になる。また、展開シートを縦Ｖ溝および横Ｖ溝に沿って折り曲げるだけでて寸法精度の高い段ボール棺を簡単に組み立てることができる。 In addition, according to the configuration of the first device, in addition to the bottom plate, the side plate, and the end plate, the sandwiching plate, the bridging plate, and the folded plate can be formed with a single developed sheet (one sheet). It becomes possible to manufacture corrugated cardboard well. Further, a corrugated board with high dimensional accuracy can be easily assembled simply by bending the developed sheet along the vertical V-groove and the horizontal V-groove.

さらに、本考案の構成では、挟み代板が側板の前後で展開シートの板厚分だけ妻板よりも内側にズレた位置で折り曲げられるため、展開シートが板厚が大きなものであっても、挟み代板と妻板とが干渉し合うことがなく、これらの板の折曲げおよび固定の作業を簡単に行うことができる。 Further, in the configuration of the present invention, the sandwiching plate is folded at a position shifted inward from the end plate by the thickness of the unfolded sheet before and after the side plate, so even if the unfolded sheet has a large plate thickness, The substitute plate and the end plate do not interfere with each other, and the bending and fixing operations of these plates can be easily performed.

［第２考案］
第２考案の組立式段ボール棺は、第１考案の構成を備えるものであって、
前記挟み代板の上端に、前記妻板の板幅とほぼ等しい幅で、かつ前記側板の上端から前記展開シートの板厚とほぼ等しい段差をもって前記架橋板を受け入れる凹溝部が設けられる構成とした。 [Second Device]
The assembly type corrugated cardboard cage of the second device has the structure of the first device,
A concave groove portion is provided at the upper end of the sandwiching margin plate so as to receive the bridge plate from the upper end of the side plate with a width substantially equal to the width of the end plate and substantially equal to the thickness of the spread sheet.

このような構成によれば、挟み代板の上方に架橋板を架け渡す際に、凹溝部に架橋板がぴったり嵌まる。このため妻板と側板との境界部分に段差がなくなり、段ボール棺の外観の見栄えを良好にすることができる。また、妻板と側板の上に棺の蓋を載せやすくすることができる。 According to such a configuration, when the bridging plate is bridged over the sandwiching margin plate, the bridging plate fits snugly into the groove portion. For this reason, there is no step at the boundary between the end plate and the side plate, and the appearance of the corrugated board can be improved. In addition, the lid of the bag can be easily placed on the end plate and the side plate.

［第３考案］
第３考案の組立式段ボール棺は、第１または２考案の構成を備えるものであって、
前記挟み代板は、左右の前記側板の先端でほぼ垂直内向きに折り曲げられて、これらのの先端が互いに隣接するように構成され、かつ、これらの隣接部分には、一方の挟み代板の板面に連なって突出するパズルピース片と、他方の挟み代板の板面に切り欠かれて開口し、前記パズルピース片に嵌合するパズルピース嵌合部とが設けられる構成とした。 [Third Device]
The assembly type corrugated cardboard cage of the third device has the structure of the first or second device,
The clamping margin plates are configured to be bent substantially vertically inwardly at the distal ends of the left and right side plates, and the distal ends thereof are adjacent to each other. A puzzle piece piece projecting continuously from the plate surface and a puzzle piece fitting portion that is cut out and opened in the plate surface of the other sandwiching plate and is fitted to the puzzle piece piece are provided.

このような構成によれば、左右の挟み代板を突き合わせてパズルピース片をパズルピース嵌合部に噛み合わせると、これらの挟み代板が同一平面上に仮止めした状態で保持される。このため、段ボール棺の組立作業、特に挟み代板に妻板、架橋板および折返し板を固定する作業が行いやすくなる。
また、パズルピース片とパズルピース嵌合部とを噛み合わせることで、左右の側板が外側に引っ張られても、左右の挟み代板が妻板、架橋板および折返し板の固定部から抜けるのが防止され、段ボール棺の固定強度をさらに向上させることができる。 According to such a configuration, when the left and right sandwiching margin plates are brought into contact with each other and the puzzle piece piece is engaged with the puzzle piece fitting portion, these sandwiching margin plates are held in a temporarily fixed state on the same plane. For this reason, it becomes easy to perform an assembling operation of the corrugated board, particularly an operation of fixing the end plate, the bridging plate and the folded plate to the sandwiching margin plate.
In addition, by engaging the puzzle piece piece and the puzzle piece fitting part, even if the left and right side plates are pulled outward, the left and right sandwiching plate is prevented from coming off from the fixed part of the end plate, bridge plate and folded plate In addition, the fixing strength of the corrugated board can be further improved.

［第４考案］
第４考案の組立式段ボール棺は、第１〜３考案のいずれか一の構成を備えるものであって、
前記展開シートには、左右のいずれか片側の前記側板および前記挟み代板の板面に、前記底板の側端から所定の間隔を保って前後方向の直線上に連なる折畳用の切れ目が設けられる構成とした。 [Fourth Device]
The assembly type corrugated cardboard cage of the fourth device comprises any one of the first to third devices,
The unfolded sheet is provided with folding cuts that are continuous on a straight line in the front-rear direction at a predetermined distance from the side edge of the bottom plate on the plate surface of the side plate on either one of the left and right sides and the sandwiching plate. It was set as the structure.

展開シートを保管・運搬等する場合には、底板、側板および妻板の各板をＶ溝に沿って組立時とは反対側に折り返して折り畳むことがある。例えば底板の下側に左右の側板を折り返して重ねると、展開シートの形態がコンパクトになりその取扱が容易になる。
ところが、第１〜３考案の構成では、底板、側板および妻板に加えて挟み代板、架橋板および折返し板が展開シートに含まれるため、上記のように展開シートを折り畳もうとすると、これらの板が邪魔になって展開シートがコンパクトな形態にならないことが起こりうる。 When storing and transporting the unfolded sheet, the bottom plate, the side plate, and the end plate may be folded back along the V-groove to the opposite side from the time of assembly. For example, when the left and right side plates are folded back and stacked on the lower side of the bottom plate, the form of the unfolded sheet becomes compact and easy to handle.
However, in the configuration of the first to third devices, in addition to the bottom plate, the side plate and the end plate, the sandwiching plate, the bridging plate and the folded plate are included in the unfolded sheet, so when trying to fold the unfolded sheet as described above, It can happen that the unfolded sheet does not become compact due to the obstruction of the plate.

第４考案の構成によれば、まず、底板の下側に左右の一方（折畳用の切れ目が存在しない方）の側板を１８０゜折返し、同時にこの側板の前後の挟み代板を、妻板の下側に重ねる。
次に、この妻板の前後の架橋板および折返し板を、断面コの字状になるように横Ｖ溝に沿って外向きに１８０゜折り返して、前述の挟み代板の下側に折返し板を重ねる。
このような状態で、他方（折畳用の切れ目が存在する方）の側板を、縦Ｖ溝と折畳用の切れ目とによりで１８０゜折り返して、先に折り返された一方の側板の下側にもって来る。すると、この側板の前後の挟み代板が前述の折返し板の下側に重なる。
このような手順によることで、展開シートを重ねてコンパクトに折り畳むことができ、保管・運搬等の取り扱いを容易にすることができる。 According to the configuration of the fourth device, first, one of the left and right side plates (the one without the folding cut) is folded 180 degrees below the bottom plate, and at the same time, the front and rear clamping plates of the side plate are Overlay on the bottom.
Next, the bridge plate and the folded plate before and after the end plate are folded 180 ° outward along the lateral V-groove so as to have a U-shaped cross section, and the folded plate is placed under the above-described sandwiching plate. Overlapping.
In this state, the other side plate (the one where the folding cut is present) is folded back 180 ° by the vertical V groove and the folding cut, and the lower side of the first folded side plate Bring it to you. Then, the clamping margin plates before and after this side plate overlap with the lower side of the folded plate.
By such a procedure, the unfolded sheets can be stacked and folded compactly, and handling such as storage and transportation can be facilitated.

なお、第４考案の構成では、折畳用の切れ目が側板に設けられる点で、このような切れ目が底板に設けられる構成（特許文献２の図５参照）とは異なる。
折畳用の切れ目が底板に存在すると、荷重が側板の切れ目付近に作用したときに棺の変形、破断等が生じやすくなる。これに対し、本考案の構成では、上記切れ目を側板側に配置しているため、段ボール棺の構造的な強度をより高く保つことが可能になる。 Note that the configuration of the fourth device is different from the configuration in which such a cut is provided in the bottom plate (see FIG. 5 of Patent Document 2) in that a cut for folding is provided in the side plate.
When the folding cuts are present in the bottom plate, deformation or breakage of the ridges is likely to occur when a load is applied in the vicinity of the side plate cuts. On the other hand, in the structure of this invention, since the said cut | interruption is arrange | positioned at the side-plate side, it becomes possible to keep the structural intensity | strength of a corrugated cardboard cage higher.

［第５考案］
前述した第１〜４考案では、展開シートにおいて側板の前後に挟み代板を設け、妻板の前後に架橋板および折返し板を設けているが、下記の第５考案に示すように、これらの位置関係を逆に配置してもよい。
このような構成によっても、第１考案と同様な作用・効果を得ることができる。 [Fifth Device]
In the first to fourth devices described above, in the unfolded sheet, a sandwiching plate is provided before and after the side plate, and a bridging plate and a folded plate are provided before and after the end plate, but as shown in the following fifth device, these positions are provided. The relationship may be reversed.
Even with such a configuration, it is possible to obtain the same operation and effect as the first device.

すなわち、第５考案の組立式段ボール棺は、
強化段ボール板からなる展開シートの縦横方向にＶ溝を形成し、このＶ溝に沿って展開シートを箱状に折り曲げて組み立てる段ボール棺であって、
矩形の底板と、
この底板の左右に縦Ｖ溝によりほぼ垂直に折り曲げられる矩形の側板と、
前記底板の前後に横Ｖ溝によりほぼ垂直に折り曲げられる矩形の妻板とを備え、
前記妻板には、前記展開シートの板厚分だけ左右方向中央側にズレた位置で、縦Ｖ溝によりほぼ垂直内向きに折り曲げられて前記側板の内側に重なる挟み代板が設けられ、
前記側板には、前記挟み代板の上方で縦Ｖ溝によりほぼ水平内向きに折り曲げられる架橋板と、この架橋板の先端から縦Ｖ溝によりほぼ垂直下向きに折り曲げられて前記挟み代板の内側に重なる折返し板とが設けられる構成とした。 That is, the assembly type corrugated cardboard cage of the fifth device is

A rectangular end plate that is bent substantially vertically by a lateral V-groove before and after the bottom plate,
The end plate is provided with a clip margin plate that is bent substantially vertically inward by a vertical V-groove and overlaps the inside of the side plate at a position shifted to the center side in the left-right direction by the plate thickness of the spread sheet,
The side plate includes a bridging plate that is bent substantially horizontally inward by a vertical V-groove above the sandwiching plate, and an inner side of the sandwiching plate that is folded substantially vertically downward by a vertical V-groove from the tip of the bridging plate. And a folded plate that overlaps with each other.

第１〜５考案の組立式段ボール棺は、強化段ボールからなる展開シートをＶ溝に沿って箱状に折り曲げる段ボール棺に適用することができる。通常は、段ボール棺の本体と蓋体のうち、本体側に本考案を適用されることが想定されるが、蓋体が箱状になっている場合には、段ボール棺の蓋体に本考案を適用してもよい。
段ボール棺の用途（人用、ペット用等）や種類（寝棺、座棺等）は、特に限定されることはない。 The assembly type corrugated cardboard cage of the first to fifth devices can be applied to a corrugated cardboard cage that bends a development sheet made of reinforced corrugated cardboard into a box shape along the V-groove. Usually, it is assumed that the present invention is applied to the main body side of the main body and the lid of the corrugated cardboard basket. However, when the lid is box-shaped, the present invention is applied to the lid of the corrugated cardboard basket. May be applied.
There are no particular limitations on the use (such as for humans and pets) and the type (such as sleeping robes and seats) of cardboard baskets.

第１〜５考案は、必要に応じて単独で適用してもよいし、これらの考案を組み合わせて適用してもよい。また、本明細書に記載される他の考案を組み合わせてもよい。 The first to fifth devices may be applied alone as necessary, or may be applied in combination of these devices. Moreover, you may combine the other idea described in this specification.

以下、本考案の実施の形態を図面に基づいて説明する。本実施形態は、段ボール棺の本体に本考案を適用したものである。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the present invention is applied to a main body of a cardboard box.

［第１実施形態］
図１に示すように、段ボール棺１０は、棺本体１２と蓋１３とからなる。棺本体１２の上方に蓋１３が載置される。蓋１３の前寄りの位置には、窓１４が設けられる。この窓１４の扉を開くことで棺の内部が覗けるようになっている。
段ボール棺１０の寸法は、例えば長さが１７０〜２００ｃｍ程度、幅が５０〜７０ｃｍ程度、棺本体１２と蓋１３を含めた高さが４０〜５０ｃｍ程度である。 [First Embodiment]
As shown in FIG. 1, the corrugated cardboard basket 10 includes a bag body 12 and a lid 13. A lid 13 is placed above the bag main body 12. A window 14 is provided at a position near the front of the lid 13. By opening the door of this window 14, the inside of the bag can be seen.
The dimensions of the corrugated cardboard basket 10 are, for example, about 170 to 200 cm in length, about 50 to 70 cm in width, and about 40 to 50 cm in height including the bag main body 12 and the lid 13.

棺本体１２および蓋１３は、強化段ボール板により形成される。強化段ボール板としては、例えば、板厚１０〜２０ｍｍ程度の三層強化段ボール材（例えばトライウォール社製）が採用される。図２のＲ部分拡大図に示すように、強化段ボール板は、２枚の厚板（ライナー）Ｒb，Ｒfとの間に、３層の波板ｒ1〜ｒ3が仕切り板ｒ4およびｒ5を介して積層されてなる。厚板（ライナー）Ｒb，Ｒfが樹脂材料で強化されることで、強化段ボール板の耐圧性・耐水性が高められている。
折曲げ用のＶ溝加工は、これらの層のうち厚板Ｒf，Ｒbのいずれかを残して他の層を回転刃等を用いて切削することにより行う。段ボール板を折り曲げる際には、残した片方の厚板（ライナー）のみを折り曲げて、Ｖ溝の傾斜する溝面を互いに密着させる。Ｖ溝の溝角がほぼ９０゜になるようにＶ溝加工を施せば、隣り合う板同士がほぼ垂直に折れ曲がる。また他のＶ溝の形成方法としては、プレス機等で段ボール板を断面Ｖ字状に圧縮してもよい。 The bag main body 12 and the lid 13 are formed of a reinforced corrugated board. As the reinforced corrugated board, for example, a three-layer reinforced corrugated board material (for example, manufactured by Triwall) having a thickness of about 10 to 20 mm is employed. As shown in the R-part enlarged view of FIG. 2, the reinforced corrugated board has three layers of corrugated plates r1 to r3 interposed between two thick plates (liners) Rb and Rf via partition plates r4 and r5. It is laminated. Since the thick plates (liners) Rb and Rf are reinforced with a resin material, the pressure resistance and water resistance of the reinforced corrugated board are increased.
V-groove processing for bending is performed by cutting one of these layers using a rotary blade or the like while leaving one of the thick plates Rf and Rb. When the corrugated board is bent, only the remaining one thick board (liner) is bent, and the inclined groove surfaces of the V groove are brought into close contact with each other. If V-groove processing is performed so that the groove angle of the V-groove is approximately 90 °, adjacent plates bend substantially vertically. As another V-groove forming method, the corrugated board may be compressed into a V-shaped cross section by a press machine or the like.

段ボール棺１０の表面には、必要に応じて布やフィルムなどの化粧シートが貼り付けられる。このような化粧仕上げ施すことで、段ボール棺１０の質感が高められる。 A decorative sheet such as a cloth or a film is affixed to the surface of the cardboard box 10 as necessary. By applying such a cosmetic finish, the texture of the corrugated cardboard 10 is enhanced.

図１に示すように、棺本体１２は、底板１２Ａと、この底板１２Ａの左右に向き合う側板１２Ｂ，１２Ｂと、底板１２Ａの前後に向き合う妻板１２Ｃ，１２Ｃとを有している。側板１２Ｂ，１２Ｂの上部には、一定の板幅で補強用の枠板１２Ｄが内側に折り返されている（図２参照）。棺本体１２の水平な上端面には、平板状の蓋１３がほぼ水平に載置される。 As shown in FIG. 1, the main body 12 includes a bottom plate 12A, side plates 12B and 12B facing the left and right of the bottom plate 12A, and end plates 12C and 12C facing the front and rear of the bottom plate 12A. On the upper side of the side plates 12B, 12B, a reinforcing frame plate 12D is folded inward with a constant plate width (see FIG. 2). A flat lid 13 is placed almost horizontally on the horizontal upper end surface of the bag main body 12.

棺本体１２を組み立てるための展開シートＰ1を図３に示した。なお、図３は、展開シートＰ1の前側部分を示しているが、後側についても同様な構造を有している。 An unfolding sheet P1 for assembling the bag main body 12 is shown in FIG. FIG. 3 shows the front side portion of the spread sheet P1, but the rear side has a similar structure.

図３に示すように、展開シートＰ1には、矩形の底板１２Ａの左右に側板１２Ｂ，１２Ｂが設けられ、底板１２Ａの前後に妻板１２Ｃが設けられる。底板１２Ａと側板１２Ｂ，１２Ｂとの境界に縦Ｖ溝ｙ1，ｙ1が形成される。底板１２Ａと妻板１２Ｃとの境界には横Ｖ溝ｘ1が形成される。
側板１２Ｂ，１２Ｂの前後には、横Ｖ溝ｘ2を隔てて挟み代板１２Ｅ，１２Ｅが設けられる。挟み代板１２Ｅ，１２Ｅは、基本的には矩形の板面を有しており、妻板１２Ｃの左右板幅のほぼ半分の長さでその前後方向（図３で上下）に延びる。 As shown in FIG. 3, the unfolded sheet P1 is provided with side plates 12B and 12B on the left and right sides of the rectangular bottom plate 12A, and with end plates 12C before and after the bottom plate 12A. Vertical V grooves y1 and y1 are formed at the boundary between the bottom plate 12A and the side plates 12B and 12B. A lateral V-groove x1 is formed at the boundary between the bottom plate 12A and the end plate 12C.
Before and after the side plates 12B and 12B, sandwiching margin plates 12E and 12E are provided with a lateral V-groove x2. The sandwiching margin plates 12E and 12E basically have a rectangular plate surface, and extend in the front-rear direction (up and down in FIG. 3) with a length approximately half of the width of the left and right plates of the end plate 12C.

図４に示すように、挟み代板１２Ｅの横Ｖ溝ｘ2は、妻板１２Ａの横Ｖ溝ｘ1よりも展開シートＰ1の板厚ｄ分だけ内側にズレた位置に設定される。これにより、挟み代板１２Ｅを横Ｖ溝ｘ2で垂直に折り曲げると、挟み代板１２Ｅの外側面が底板１２Ａの板面先端位置Ｌに来る。これにより、展開シートＰ1の板厚が大きくても、挟み代板１２Ｅと妻板１２Ａとが互いに干渉し合うことなく、前後に重なった位置に立ち上がる。 As shown in FIG. 4, the lateral V groove x2 of the clamping margin plate 12E is set at a position displaced inward by the thickness d of the spread sheet P1 from the lateral V groove x1 of the end plate 12A. Accordingly, when the clamping margin plate 12E is bent vertically at the lateral V groove x2, the outer side surface of the clamping margin plate 12E comes to the plate surface tip position L of the bottom plate 12A. Thereby, even if the plate | board thickness of the expansion | deployment sheet | seat P1 is large, the clamping margin board 12E and the end plate 12A stand up to the position which overlapped front and back, without mutually interfering.

図３に示すように、挟み代板１２Ｅ，１２Ｅの先端部には、パズルピース片１２ｐと、パズルピース嵌合部１２ｈとが設けられる。パズルピース片１２ｐは、一方の挟み代板１２Ｅの先端から延び、他方の挟み代板１２Ｅの先端に切り欠かれたパズルピース嵌合部１２ｈに嵌まる（図６，図８参照）。パズルピース片１２ｐとパズルピース嵌合部１２ｈの根元付近は、両端から内向きに湾曲状にくびれており、これらのくびれ部分が引っ掛かって両者の係合状態を保つ。 As shown in FIG. 3, the puzzle piece piece 12p and the puzzle piece fitting part 12h are provided in the front-end | tip part of the clamping margin plates 12E and 12E. The puzzle piece piece 12p extends from the tip end of one pinch allowance plate 12E and fits into the puzzle piece fitting portion 12h cut out at the tip end of the other pinch allowance plate 12E (see FIGS. 6 and 8). The vicinity of the base of the puzzle piece piece 12p and the puzzle piece fitting portion 12h is constricted inwardly from both ends, and these constricted portions are hooked to maintain the engaged state of both.

妻板１２Ａ，１２Ａの前後には、横Ｖ溝ｘ3およびｘ4を隔てて架橋板１２Ｆおよび１２Ｇが設けられる。架橋板１２Ｆおよび折返し板１２Ｇの図３で左右方向の幅は、妻板１２Ａと等しい。架橋板１２Ｆの前後方向の長さは、展開シートＰ1の板厚にほぼ等しく、折返し板１２Ｇの前後方向の長さは、妻板１２Ａよりも展開シートＰ1の板厚分だけ短く設定されている。 Before and after the end plates 12A and 12A, cross-linking plates 12F and 12G are provided with a lateral V-groove x3 and x4 therebetween. The width in the left-right direction in FIG. 3 of the bridge plate 12F and the folded plate 12G is equal to the end plate 12A. The length in the front-rear direction of the bridging plate 12F is substantially equal to the thickness of the developed sheet P1, and the length in the front-rear direction of the folded plate 12G is set to be shorter than the end plate 12A by the thickness of the developed sheet P1.

展開シートＰ1の左右両端部には、Ｗ溝（ほぼ９０゜角にカットされたＶ溝を２列に並設して形成した溝）により枠板１２Ｄが折り返されている（図３参照）。枠板１２Ｄは、棺本体１２の開口端部を補強するものである。 Frame plates 12D are folded back at the left and right ends of the unfolded sheet P1 by W grooves (grooves formed by arranging V grooves cut at approximately 90 ° in parallel in two rows) (see FIG. 3). The frame plate 12D reinforces the opening end portion of the bag main body 12.

棺本体１２を組み立てる場合、例えばまず、図５に示すように、底板１２Ａの左右で縦Ｖ溝ｙ1，ｙ1（図３参照）に沿って側板１２Ｂ，１２Ｂをほぼ垂直に折り曲げて立ち上げる。このとき、同時に側板１２Ｂ，１２Ｂの前後で挟み代板１２Ｅ，１２Ｅが垂直に保たれる。
次いで、これらの挟み代板１２Ｅ，１２Ｅを横Ｖ溝ｘ2に沿って観音扉状にほぼ垂直に折り曲げ、これらの先端を突き合わせる。このとき、図６に示すように、パズルピース片１２ｐをパズルピース嵌合部１２ｈに嵌め合わせることで、挟み代板１２Ｅ，１２Ｅが同一平面状に仮止めされることになる。 When assembling the bag body 12, for example, as shown in FIG. 5, first, the side plates 12B and 12B are bent substantially vertically along the vertical V grooves y1 and y1 (see FIG. 3) on the left and right sides of the bottom plate 12A. At this time, the sandwiching margin plates 12E and 12E are kept vertical before and after the side plates 12B and 12B.
Next, these clamping strips 12E, 12E are bent substantially vertically into a kannon door shape along the lateral V-groove x2, and these tips are butted. At this time, as shown in FIG. 6, by inserting the puzzle piece piece 12p into the puzzle piece fitting portion 12h, the sandwiching margin plates 12E and 12E are temporarily fixed on the same plane.

底板１２Ａの前後で挟み代板１２Ｅ，１２Ｅを折り曲げた後、図７に示すように、妻板１２Ｃを横Ｖ溝ｘ1に沿って折り曲げて上方に起こし、その先端で架橋板１２Ｆを横Ｖ溝ｘ3で折り曲げ、さらにその先端で折返し板１２Ｇを横Ｖ溝ｘ4で内向きに折り曲げる。そして、図９に示すように、挟み代板１２Ｅを抱き込むように各板を断面コの字状に折り曲げ、互いの板面を密着させて接着剤、接着テープ等で固定する。そして、必要に応じて他の板の接触部についても接着剤、接着テープ等で固定する。具体的には、縦Ｖ溝ｙ1、横Ｖ溝ｘ1〜ｘ4、Ｗ溝の各固定部、パズルピース片１２ｐとパズルピース嵌合部１２ｈとの固定部、枠板１２Ｄの固定部等についても接着剤、接着テープ等で補強することが望ましい。 After the sandwiching margin plates 12E and 12E are bent before and after the bottom plate 12A, as shown in FIG. 7, the end plate 12C is bent along the horizontal V-groove x1 and raised upward, and the bridging plate 12F is set to the horizontal V-groove x3 at its tip. And the folded plate 12G is bent inward at the front end thereof by the lateral V-groove x4. Then, as shown in FIG. 9, each plate is folded into a U-shaped cross section so as to embrace the sandwiching margin plate 12 </ b> E, and the plate surfaces are brought into close contact with each other and fixed with an adhesive, an adhesive tape, or the like. And the contact part of another board is also fixed with an adhesive agent, an adhesive tape, etc. as needed. Specifically, the vertical V groove y1, the horizontal V grooves x1 to x4, the fixed portions of the W groove, the fixed portion of the puzzle piece piece 12p and the puzzle piece fitting portion 12h, the fixed portion of the frame plate 12D, and the like are also bonded. It is desirable to reinforce with an agent, adhesive tape or the like.

展開シートＰ1の折曲げ順序については、上記に限定されることなく、側板１２Ｂ，１２Ｂよりも先に挟み代板１２Ｅを折り曲げるようにしてもよい。展開シートＰ1が図１に示す箱形状に折り曲げられるものであれば折曲げ順序は問わない。 The folding order of the unfolding sheet P1 is not limited to the above, and the sandwiching plate 12E may be folded before the side plates 12B and 12B. As long as the unfolded sheet P1 can be folded into the box shape shown in FIG.

ここで、図６に示すように、仮止め状態の挟み代板１２Ｅ，１２Ｅの上端部には、凹溝部１２ｓが形成される。凹溝部１２ｓは、妻板１２Ｃの板幅とほぼ等しい幅で、側板１２Ｂ，１２Ｂの上端から展開シートＰ1の板厚と等しい段差に形成される。
これにより、挟み代板１２Ｅ，１２Ｅの上方に架橋板１２Ｆを架け渡すと、凹溝部１２ｓに架橋板１２Ｆがぴったり嵌って妻板１２Ｃと側板１２Ｂ，１２Ｂとの境界部分に段差がなくなり、両者の上端面が均一な高さに揃う。そして、棺本体１２の上端に蓋１３を水平状態で安定的に載置することが可能になる。 Here, as shown in FIG. 6, a recessed groove portion 12 s is formed at the upper end portion of the clamping margin plates 12 </ b> E and 12 </ b> E in the temporarily fixed state. The concave groove portion 12s has a width substantially equal to the width of the end plate 12C and is formed at a level difference equal to the thickness of the spread sheet P1 from the upper end of the side plates 12B and 12B.
As a result, when the bridging plate 12F is bridged over the sandwiching margin plates 12E and 12E, the bridging plate 12F is fitted into the groove 12s so that there is no step at the boundary between the end plate 12C and the side plates 12B and 12B. End faces are evenly aligned. Then, the lid 13 can be stably placed on the upper end of the bag main body 12 in a horizontal state.

このように段ボール棺１０によれば、側板１２Ｂの先端で折り曲げられる挟み代板１２Ｅに、妻板１２Ｃ、架橋板１２Ｆおよび折返し板１２Ｇの各板面を広く接触させることができる。このため、各板の固定強度を高めて段ボール棺１０の耐荷重性を大幅に向上させることができる。 As described above, according to the corrugated cardboard cage 10, the plate surfaces of the end plate 12C, the bridging plate 12F, and the folded plate 12G can be brought into wide contact with the sandwiching margin plate 12E that is bent at the tip of the side plate 12B. For this reason, the fixing strength of each plate can be increased and the load bearing ability of the corrugated board bag 10 can be greatly improved.

また、段ボール棺１０によれば、底板１２Ａ、側板１２Ｂおよび妻板１２Ｃに加えて挟み代板１２Ｅ、架橋板１２Ｆおよび折返し板１２Ｇを単一の展開シート（ワンシート）で形成することができるため、低コストで効率よく段ボール棺１０を製造することが可能になる。また、展開シートＰ1を縦Ｖ溝ｙ1および横Ｖ溝ｘ1〜ｘ4に沿って折り曲げるだけで、寸法精度の良好な段ボール棺１０を簡単に組み立てることができる。 Further, according to the corrugated cardboard cage 10, in addition to the bottom plate 12A, the side plate 12B, and the end plate 12C, the sandwiching plate 12E, the bridging plate 12F, and the folded plate 12G can be formed as a single development sheet (one sheet). It becomes possible to manufacture the corrugated cardboard cage 10 efficiently at a low cost. Further, the corrugated cardboard trough 10 with good dimensional accuracy can be easily assembled only by bending the spread sheet P1 along the vertical V-groove y1 and the horizontal V-grooves x1 to x4.

さらに、段ボール棺１０では、挟み代板１２Ｅ，１２Ｅが妻板１２Ｃよりも底板１２Ａの前後方向中央側に展開シートＰ1の板厚分だけズレた位置にあるから、これらの折り曲げ部分で各板が邪魔し合うことがない。このため、展開シートＰ1の板厚が大きくても、挟み代板１２Ｅ，１２Ｅと妻板１２Ａとの折り曲げかつ固定の作業を簡単かつスムーズに行うことができる。 Further, in the corrugated cardboard cage 10, the sandwiching margin plates 12E and 12E are located at the center of the bottom plate 12A in the longitudinal direction of the bottom plate 12A with respect to the center plate 12A in the longitudinal direction, so that each plate is obstructed by these bent portions. I don't get along. For this reason, even if the plate | board thickness of the expansion | deployment sheet | seat P1 is large, the operation | work of bending and fixing with the pinching margin plates 12E and 12E and the end plate 12A can be performed easily and smoothly.

次に、展開シートＰ1の折り畳み方法を説明する。
展開シートＰ1を折り畳んで保管・運搬等する場合には、組立時とは反対側に各板を折り畳むことにより展開シートＰ1をコンパクトな形態にする。 Next, a method for folding the spread sheet P1 will be described.
When the unfolded sheet P1 is folded and stored or transported, the unfolded sheet P1 is made compact by folding each plate on the side opposite to that during assembly.

この場合、例えば図３に示すように、左右の側板１２Ｂ，１２Ｂおよび挟み代板１２Ｅ，１２Ｅのうちの片側の板面であって図３の二点鎖線の位置に折畳用の切れ目Ｋを入れる。この切れ目Ｋは、底板１２Ａの側端から展開シートＰ1の所定間隔（展開シートＰ1の板厚２枚以上の幅）を保って前後方向の直線上に連なる。展開シートＰ1の各Ｖ溝と同様に、最も下のライナー層（図２の符号Ｒｆ参照）を残して他の層をカッター等で平面的に切断する。 In this case, for example, as shown in FIG. 3, a folding cut K is provided at the position of the two-dot chain line in FIG. 3 on one side of the left and right side plates 12B and 12B and the clamping margin plates 12E and 12E. Put in. The cut K is continuous from the side edge of the bottom plate 12A on a straight line in the front-rear direction while maintaining a predetermined interval of the developing sheet P1 (a width of two or more sheets of the developing sheet P1). Similarly to the V grooves of the unfolding sheet P1, the other layers are cut planarly with a cutter or the like while leaving the lowermost liner layer (see reference numeral Rf in FIG. 2).

図１０は、展開シートＰ1を折り畳む工程を説明するための断面図で、図１０（Ａ）および（Ｃ）は展開シートＰ1の横断面図、図１０（Ｂ）は展開シートＰ1の妻板付近の部分縦断面図である。なお、図１０（Ａ）では、展開シートＰ1の構造を分かりやすくするため、側板１２Ｂ，１２Ｂを垂直に起こした状態で描いている。 FIG. 10 is a cross-sectional view for explaining the process of folding the unfolded sheet P1, FIGS. 10A and 10C are cross-sectional views of the unfolded sheet P1, and FIG. 10B is the vicinity of the end plate of the unfolded sheet P1. It is a partial longitudinal cross-sectional view. In FIG. 10A, the side plates 12B and 12B are drawn vertically in order to make the structure of the spread sheet P1 easy to understand.

展開シートＰ1を折り畳む場合、図１０（Ａ）矢印ａに示すように、まず、底板１２Ａの下側に右側の側板１２Ｂを外向きに折返して重ね、同時にこの側板１２Ｂの前後の挟み代板１２Ｅを外向きに折り返して妻板１２Ｃの下側に折り返して重ねる（図１０（Ｂ）参照）。 When the unfolding sheet P1 is folded, as shown by an arrow a in FIG. 10A, first, the right side plate 12B is folded outwardly and overlapped on the lower side of the bottom plate 12A, and at the same time, the sandwiching margin plates 12E before and after the side plate 12B. Is folded outward and folded over the lower side of the end plate 12C (see FIG. 10B).

次いで、図１０（Ｂ）矢印ｂに示すように、妻板１２Ｃ、架橋板１２Ｆおよび折返し板１２Ｇを横Ｖ溝ｘ3，ｘ4に沿って外側に向けて断面コの字状に折り返し、前述の挟み代板１２Ｅの下に折返し板１２Ｇを重ねる。 Next, as shown by an arrow b in FIG. 10B, the end plate 12C, the bridging plate 12F, and the folded plate 12G are folded back outwardly along the lateral V-grooves x3 and x4 to form a U-shaped cross section. The folded plate 12G is stacked under the plate 12E.

このような状態で、図１０（Ｃ）矢印ｃに示すように、切れ目Ｋのある左側の側板１２Ｂを縦Ｖ溝ｙ1と切れ目Ｋとにより断面コの字状に折り返す。すると、側板１２Ｂの前後の挟み代板１２Ｅが前述の折返し板１２Ｇ（図１０（Ｃ）参照）の下側に重なることになる。 In this state, as shown by an arrow c in FIG. 10C, the left side plate 12B having the cut K is folded back into a U-shaped cross section by the vertical V groove y1 and the cut K. Then, the clamping margin plates 12E before and after the side plate 12B overlap the lower side of the above-described folded plate 12G (see FIG. 10C).

このように展開シートＰ1に底板１２Ａの側端から所定間隔だけ離れた位置に切れ目Ｋを入れることで、挟み代板１２Ｅや折返し板１２Ｇが邪魔になることなく、展開シートＰ1を４枚分の板厚に重ねてコンパクトに折り畳むことができる。これにより、展開シートＰ1の保管・運搬等の取り扱いを容易にすることができる。 In this way, the cut sheet K is formed at a position spaced apart from the side edge of the bottom plate 12A by a predetermined distance in the spread sheet P1, so that the four spread sheets P1 can be obtained without obstructing the clamping margin plate 12E and the folding plate 12G. It can be folded compactly over the plate thickness. Thereby, handling, such as storage and conveyance of the expansion | deployment sheet | seat P1, can be made easy.

［第２実施形態］
次に、本考案の第２実施形態を図１１〜図１３に示した。
第２実施形態の段ボール棺２０は、妻板１２Ｃの左右に挟み代板１２Ｅ，１２Ｅを設け、側板１２Ｂ，１２Ｂの左右に架橋板１２Ｆおよび折返し板１２Ｇを設けたものである。 [Second Embodiment]
Next, a second embodiment of the present invention is shown in FIGS.
In the corrugated cardboard cage 20 of the second embodiment, sandwiching margin plates 12E, 12E are provided on the left and right sides of the end plate 12C, and a bridging plate 12F and a folding plate 12G are provided on the left and right sides of the side plates 12B, 12B.

図１１に示すように、段ボール棺２０の展開シートＰ2は、底板１２Ａの左右に縦Ｖ溝ｙ1を隔てて側板１２Ｂ，１２Ｂが設けられる。底板１２Ａの前後には横Ｖ溝ｘ1を隔てて妻板１２Ｃが設けられる。 As shown in FIG. 11, the unfolding sheet P2 of the cardboard box 20 is provided with side plates 12B and 12B with a vertical V groove y1 on the left and right sides of the bottom plate 12A. A front plate 12C is provided before and after the bottom plate 12A with a lateral V-groove x1 therebetween.

妻板１２Ｃの左右には、縦Ｖ溝ｙ2を隔てて舌板状の挟み代板１２Ｅ，１２Ｅが設けられる。縦Ｖ溝ｙ2は、縦Ｖ溝ｙ1よりも展開シートＰ2の板厚分だけ内側にズレた位置にあり、これにより挟み代板１２Ｅ，１２Ｅが側板１２Ｂ，１２Ｂよりも展開シートＰ2の板厚分だけ左右方向の中央側で折り曲げられることになる。 Tongue plates 12E and 12E in the form of tongue plates are provided on the left and right sides of the end plate 12C with a vertical V groove y2 therebetween. The vertical V-groove y2 is located at a position shifted inward by the thickness of the development sheet P2 from the vertical V-groove y1, so that the sandwiching margin plates 12E and 12E are equal to the thickness of the development sheet P2 than the side plates 12B and 12B. It will be bent only at the center in the left-right direction.

側板１２Ｂ，１２Ｂの左右には、それぞれ縦Ｖ溝ｙ3，ｙ4を隔てて架橋板１２Ｆおよび折返し板１２Ｇが設けられる。架橋板１２Ｆは、展開シートＰ2の板厚分の幅を有し、折返し板１２Ｇは、側板１２Ｂの左右板幅よりも展開シートＰ2の板厚分だけ短い。 A bridging plate 12F and a folded plate 12G are provided on the left and right sides of the side plates 12B and 12B with vertical V grooves y3 and y4, respectively. The bridging plate 12F has a width corresponding to the plate thickness of the spread sheet P2, and the folded plate 12G is shorter than the left and right plate widths of the side plates 12B by the plate thickness of the spread sheet P2.

段ボール棺２０を組み立てる場合、例えば図１２に示すように、底板１２Ａの左右で側板１２Ｂ，１２Ｂを立ち上げ、架橋板１２Ｆおよび折返し板１２Ｇを断面コの字状に折り曲げる。このとき、折返し板１２Ｇの下端は、側板１２Ｂの高さより板厚一枚分だけ短いため、底板１２Ａの板面に載った状態となる。
次いで、妻板１２Ｃの前後でＷ溝ｘ5（図１１参照）に沿って枠板１２Ｄを１８０゜折り返し、左右の挟み代板１２Ｅ、１２Ｅをほぼ垂直に立ち上げて、側板１２Ｂ、架橋板１２Ｆおよび折返し板１２Ｇで囲まれる矩形空間に挿入しつつ、ほぼ垂直になる位置まで立ち上げる（図１３参照）。 When assembling the corrugated cardboard cage 20, for example, as shown in FIG. 12, the side plates 12B and 12B are raised on the left and right sides of the bottom plate 12A, and the bridging plate 12F and the folded plate 12G are bent into a U-shaped cross section. At this time, since the lower end of the folded plate 12G is shorter than the height of the side plate 12B by one plate thickness, the folded plate 12G is placed on the plate surface of the bottom plate 12A.
Next, the frame plate 12D is turned back 180 ° along the W groove x5 (see FIG. 11) before and after the end plate 12C, and the left and right sandwiching plates 12E and 12E are raised almost vertically, and the side plate 12B, the bridge plate 12F and the turnup are turned up. While being inserted into a rectangular space surrounded by the plate 12G, it rises to a position that is substantially vertical (see FIG. 13).

第２実施形態の段ボール棺２０によれば、妻板１２Ｃの左右の挟み代板１２Ｅ，１２Ｅを、側板１２Ｂ、架橋板１２Ｆおよび折返し板１２Ｇの板面に広い範囲で接触させることができる。このため、これらの接触部分を接着剤、接着テープ等で固定することで、段ボール棺２０の耐荷重性を高めることができる。
また、単一の展開シートＰ2に各板が形成されるから、段ボール棺２０の組立を精度よく簡単に行うことができる。
さらには、挟み代板１２Ｅの折り曲げ位置が側板１２Ｂよりも底板１２Ａの左右方向の中央側に展開シートＰ2の板厚分だけズレて設定されるため、展開シートＰ2の板厚が大きくても、側板１２Ｂと挟み代板１２Ｅとを左右方向に重ねて垂直に保つことができ、展開シートＰ2の折り曲げ作業を行いやすくすることができる。 According to the corrugated cardboard cage 20 of the second embodiment, the left and right sandwiching margin plates 12E, 12E of the end plate 12C can be brought into contact with the plate surfaces of the side plate 12B, the bridge plate 12F, and the folded plate 12G in a wide range. For this reason, the load resistance of the corrugated paper bag 20 can be improved by fixing these contact portions with an adhesive, an adhesive tape, or the like.
Further, since each plate is formed on a single spread sheet P2, the corrugated board 20 can be assembled easily and accurately.
Furthermore, the folding position of the clamping margin plate 12E is set so as to be shifted from the side plate 12B to the center side in the left-right direction of the bottom plate 12A by the thickness of the development sheet P2, so that even if the thickness of the development sheet P2 is large, The side plate 12B and the sandwiching margin plate 12E can be kept vertical by being overlapped in the left-right direction, and it is possible to facilitate the folding operation of the spread sheet P2.

［変形例］
以上、第１および第２実施形態を説明したが、本考案の実施形態はこれらに限定されることなく、下記の通り種々の変形・変更を伴ってもよい。
例えば、図９（Ａ）および（Ｂ）に示すように、棺本体１２の内側に、底板１２Ａの板面とほぼ等しい形状の内底板Ｊを落とし込むようにしてもよい。このような構成では、内底板Ｊの前後方向の先端で折返し板１２Ｇの先端を止めて上方への跳ね上がりを防止することができる。このため、接着剤、接着テープ等を使用しなくとも、棺本体１２の箱形状を強固に固定することが可能になる。
その他の形態としては、第１および第２実施形態において、枠板１２Ｄについては、必ずしも設ける必要はなく、必要に応じて省略した構成としてもよい。
第１および第２実施形態では、棺本体１２に本考案を適用しているが、蓋１３が箱状である場合には、蓋１３に本考案を適用してもよい。
さらに、展開シートＰ1，Ｐ2を作製するための段ボール材は、三層強化段ボールに限られず、その他の多層段ボール材、ハニカム構造の段ボール材等を用いてもよい。 [Modification]
The first and second embodiments have been described above, but the embodiments of the present invention are not limited to these, and may be accompanied by various modifications and changes as described below.
For example, as shown in FIGS. 9A and 9B, an inner bottom plate J having a shape substantially equal to the plate surface of the bottom plate 12 </ b> A may be dropped inside the bag main body 12. In such a configuration, the front end of the folded plate 12G can be stopped at the front-rear direction front end of the inner bottom plate J to prevent upward jumping. For this reason, it becomes possible to firmly fix the box shape of the bag main body 12 without using an adhesive, an adhesive tape, or the like.
As other forms, in the first and second embodiments, the frame plate 12D is not necessarily provided, and may be omitted as necessary.
