Description

本発明は、荷物を目的場所に運送した後、空箱を送り返し、あるいは保管して再使用を繰返す折りたたみ式通い箱に関するものである。 The present invention relates to a folding return box that transports a package to a destination and then returns the empty box or stores it and reuses it again.

この種の通い箱としては、従来一般に紙ダンボール製のものが用いられていた。紙ダンボール箱は、軽量、安価、かつ折りたたみが容易である利点があるが、素材自体が丈夫でないこと、耐圧性に劣り重ね積みしたときに型くずれしやすいこと、水に弱いこと、またガムテープなどで梱包されるので剥がすときに箱の表皮がガムテープ等と一体に剥がれること、などの問題があって使い捨てされるのがほとんどである。 As this type of returnable box, a paper cardboard box has been generally used. Paper cardboard boxes have the advantages of being lightweight, inexpensive, and easy to fold, but the materials themselves are not strong, they are inferior in pressure resistance, easily deformed when stacked, weak against water, Since it is packaged, it is often thrown away due to problems such as peeling of the skin of the box together with the gum tape or the like when it is peeled off.

そこで紙ダンボール製の通い箱に代えてプラスチック製の通い箱が使用されるようになってきた。しかしながらプラスチック製の通い箱はこれを折りたたみ式にするためには、構成各プラスチック板をヒンジ具などで結合しなければならず、また種々の付属部品が必要となる。 Therefore, plastic returnable boxes have been used instead of paper cardboard returnable boxes. However, in order to make the plastic returnable box foldable, the constituent plastic plates must be connected with hinges or the like, and various accessory parts are required.

例えば下記特許文献１に記載のプラスチック製の通い箱は、直方形体形状の六面がプラスチック板で構成され、底板の四辺に、立上がり面をなす側板がそれぞれヒンジ結合され、一つの側板の上縁に蓋板がヒンジ結合されている。側面四面のうち一方の対向二側面はそれぞれ高さ方向中央で分割され互いにヒンジ結合された上下二枚の分割板からなり、上記一方の対向二面の側板は縦縁同士が紐で連結してあり、他方の対向二側面の側板が外側へ倒れないようにしてある。空箱の折りたたみは、先ず他方の対向二側板を底板上に倒し、次に上記一方の対向二面の下側の分割板を内側に倒しつつ上側の分割板を外側に倒して上下の分割板を上下に重ね合わせ、その上に蓋板を倒して重ね合わせることで全体を折りたたむ構造とされている。紐は変形自在であるから側板の折りたたみに支障をきたさない。
特開平９−３９９５５号公報 For example, in the plastic return box described in Patent Document 1 below, the six sides of a rectangular parallelepiped shape are made of plastic plates, and the side plates forming the rising surfaces are hinged to the four sides of the bottom plate, and the upper edge of one side plate. The lid plate is hinged to the lid. Of the four side surfaces, one opposing two side surfaces are each composed of two upper and lower divided plates that are divided at the center in the height direction and are hinged to each other. There is a side plate on the other two opposite sides so as not to fall outward. The folding of the empty box is performed by first lowering the other opposing two-side plate on the bottom plate, and then lowering the lower dividing plate on one of the opposing two surfaces inward and lowering the upper dividing plate outward to bring the upper and lower dividing plates It is set as the structure which folds the whole by putting up and down on top and falling down and putting a cover plate on it. Since the string is freely deformable, it does not interfere with the folding of the side plate.
Japanese Patent Laid-Open No. 9-39955

しかしながら上記従来のプラスチック製の折りたたみ式通い箱では各プラスチック板をヒンジ結合しなければならず、また紐を取付けなければならない。この紐は梱包したときに側板の外面に沿ってかけ渡されているから、運搬時に擦れたり、他の物に引っ掛かったりして傷みやすい。また箱を折りたたんだときに、面積を底板および蓋板以下にコンパクト化することができない。 However, in the conventional plastic folding return box, each plastic plate must be hinged and a string must be attached. Since this string is stretched along the outer surface of the side plate when packed, it is easily damaged by being rubbed during transportation or caught by other objects. Further, when the box is folded, the area cannot be made smaller than the bottom plate and the cover plate.

そこで本発明は、従来のプラスチック製の折りたたみ式通い箱よりも軽量でかつ同等の耐久性、耐圧性を有し、折りたたみ式とするために特別の部品を必要とせず、折りたたんだときに従来のものよりもコンパクト化できる折りたたみ式通い箱を提供することを課題としてなされたものである。 Therefore, the present invention is lighter than a conventional plastic folding return box, has the same durability and pressure resistance, does not require any special parts to be foldable, and does not require conventional parts when folded. An object of the present invention is to provide a collapsible returnable box that can be made more compact than an object.

本発明の折りたたみ式通い箱は、直方体形状の通い箱の底面部および蓋部を布で形成し、側面部四面を内外二重の布の間にプラスチック板を挟み込んで形成し、上記側面部四面のうち一方の対向二側面部では、プラスチック板を幅方向に分割した二枚の分割板で構成して分割線位置で折りたたみ可能とし、上記対向二側面部のうちの一方の側面部の上縁に蓋部の一辺を接続したことを特徴とする（請求項１）。 The folding return box of the present invention is formed by forming the bottom and lid portions of a rectangular parallelepiped return box with cloth, and forming the four side faces by sandwiching a plastic plate between the inner and outer double cloth. One of the opposing two side surface portions is composed of two divided plates obtained by dividing the plastic plate in the width direction, and can be folded at the position of the dividing line. One side of the lid portion is connected to the base (claim 1).

本発明の通い箱の折りたたみは、空箱の蓋部を、これが接続された側面部の外面に重ね合せ、蓋部を重ね合せた側面部とこれと対向する側面部を対向方向に押し込んで分割板の分割線位置で折り曲げて両側面部をそれぞれ重ね合わせ状態とし、重ねあわされた上記両側面部を他の対向側二面部で挟み込むことで容易になされ得る。この場合、底面および蓋部は布のみで形成されているから折りたたみ自由であり、通い箱の折りたたみの障害とはならない。 The folding of the returnable box according to the present invention is performed by overlapping the lid portion of the empty box on the outer surface of the side portion to which the empty box is connected, and pushing the side portion overlapped with the lid portion and the side portion opposite thereto into the opposing direction. It can be easily done by folding the plate at the dividing line position of the plate so that both side portions are overlapped and sandwiching the overlapped both side portions between the other two opposite sides. In this case, since the bottom surface and the lid portion are formed only of cloth, they can be folded freely and do not hinder the folding of the returnable box.

上記通い箱において、平面形状が正方形のものについては、上記分割線位置を上記一方の対向二側面部の幅方向中心に設定する（請求項２）。平面形状が長方形のものについては長辺側の対向二側面部に上記分割板を設け、上記対向二側面部の分割板の分割線位置を、互いに幅方向にずれた位置に設定し、上記対向二側面を内側に折りたたんだときに両者がぶつかり合わないようにする（請求項３）。 In the return box, when the planar shape is a square, the dividing line position is set to the center in the width direction of the one opposite two side surface portion (Claim 2). When the planar shape is rectangular, the dividing plate is provided on the opposite two side surfaces on the long side, and the dividing line positions of the dividing plates on the opposite two side surfaces are set to positions shifted in the width direction, and the opposing When the two side surfaces are folded inward, they do not collide with each other (Claim 3).

上記通い箱において、プラスチック板としてプラスチック段ボール板を用いる（請求項４）。通い箱の側面部の上下方向の耐圧性を重量を上げることなく強化することができる。 In the return box, a plastic corrugated board is used as the plastic board. The pressure resistance in the vertical direction of the side part of the returnable box can be enhanced without increasing the weight.

プラスチック板として段ボール板を用いた上記通い箱において、少なくともプラスチック板を分割板とした上記一方の対向側面部以外の他の対向側面部では、外側の布の内面にプラスチック平板を重ね合わせ、ほぼ逆Ｕ字形に曲げた帯状の持ち手の脚部を上記プラスチック平板と一体に外側の布の外面に縫着する（請求項５）。プラスチック平板で裏打ちされた側面部の布に持ち手を縫着したから持ち手は強固に側面部に取付けられる。また裏打ち材は平板であるから持ち手は容易に縫着され得る。 In the returnable box using a corrugated cardboard as a plastic plate, at least the opposite side surface portion other than the one opposite side surface portion using the plastic plate as a divided plate, a plastic flat plate is superposed on the inner surface of the outer cloth, and almost reversed. The belt-shaped handle leg bent in a U-shape is sewn to the outer surface of the outer cloth together with the plastic flat plate. Since the handle is sewn on the cloth of the side part lined with the plastic flat plate, the handle is firmly attached to the side part. Further, since the backing material is a flat plate, the handle can be easily sewn.

本発明の通い箱は布製で、側面四面にのみプラスチック板を設ける構造としたから、全体がプラスチック板からなる通い箱に比べて軽量である。また布のみの部分で折りたたまれるから、折りたたみ部にヒンジ具等の部品を用いる必要がない。 Since the returnable box of the present invention is made of cloth and has a structure in which the plastic plate is provided only on the four side surfaces, the whole is lighter than a returnable box made of a plastic plate. Moreover, since it folds only by the part of cloth, it is not necessary to use components, such as a hinge tool, for a folding part.

本発明の通い箱は、上下方向の折りたたみ式ではなく、幅方向に折りたたまれる。通い箱は、荷物を収納したときの安定性から一般に縦面となる側面部の高さが底面部（蓋部）の一辺の長さよりも小さくしてあるから、折りたたんだときの面積が上下方向に折りたたむものよりもコンパクトになる。 The returnable box of the present invention is not folded in the vertical direction, but is folded in the width direction. Since the height of the side part which becomes a vertical surface is generally smaller than the length of one side of the bottom part (lid part), the area of the returnable box when it is folded is vertical. It is more compact than what you fold.

本発明の通い箱は縦面となる側面部四面にはプラスチック板が設けられているから、重ね乗せしても充分な耐圧力がある。なお、側面部二面には折りたたまれる分割線が存在するが、分割線は縦方向であるから側面部の耐圧力を減少させるものではない。 Since the returnable box of the present invention is provided with plastic plates on the four sides of the vertical side, there is sufficient pressure resistance even when stacked. In addition, although the dividing line which can be folded exists in two side surface parts, since the dividing line is a vertical direction, it does not reduce the pressure resistance of a side part.

本発明の実施形態を図１ないし図５により説明する。図示の折りたたみ式通い箱は長方形（矩形）の底面部１および蓋部２と、側面部四面３Ａ，３Ｂ，３Ｃ，３Ｄとからなる直方体形状で、紙系書類等の運送に好適に用いられるものである。側面部３Ａ，３Ｂ，３Ｃ，３Ｄの高さ寸法は、底部１および蓋部２の短辺の寸法と同じ、ないしはそれよりも若干小さくしてある。 An embodiment of the present invention will be described with reference to FIGS. The illustrated folding-type return box has a rectangular parallelepiped shape composed of a rectangular (rectangular) bottom surface portion 1 and a lid portion 2 and four side surface portions 3A, 3B, 3C, 3D, and is suitably used for transporting paper documents and the like. It is. The height dimensions of the side surfaces 3A, 3B, 3C, 3D are the same as or slightly smaller than the dimensions of the short sides of the bottom 1 and the lid 2.

通い箱は、底面部１および蓋部２が、それぞれ一枚の布からなり、側面部３Ａ〜３Ｄはそれぞれ内外二枚の布の間にプラスチック板が挟み込んである。布はポリエチレン繊維やナイロン系の繊維など丈夫な繊維の織布で、表面に防水処理を施したものが用いられる。 In the returnable box, the bottom surface portion 1 and the lid portion 2 are each made of a single cloth, and the side surface portions 3A to 3D are each sandwiched between two inner and outer cloths. The cloth is a woven cloth made of strong fibers such as polyethylene fibers or nylon fibers, and the surface is waterproofed.

側面部四面のうち、短辺側の相対向する側面部３Ｃ，３Ｄは同一構造で、これを側面部３Ｃについて説明すると、第１図および第２図に示すように、布は内生地４ａと外生地４ｂの二重構造で、両者間には側面部３Ｃの形状と同じ四角形状のプラスチック段ボール板５と薄いプラスチック平板５０が挟みこまれている。ダンボール板５は、相対向する平板状のプラスチック薄板間が多数の仕切板により全高さにわたって幅方向に仕切られた構造としてある。なお段ボール板としては、これに限らず、波形のプラスチック板の両面に平板のライナーを設けたもの等が用いられ得る。プラスチック平板５０は外生地４ｂと上記段ボール板５の間に挿置されている。 Of the four side surfaces, the side surfaces 3C and 3D facing each other on the short side have the same structure, and this will be described with respect to the side surface portion 3C. As shown in FIGS. In the double structure of the outer fabric 4b, a rectangular plastic corrugated board 5 and a thin plastic flat plate 50, which are the same as the shape of the side surface portion 3C, are sandwiched between them. The corrugated board 5 has a structure in which flat plastic thin plates facing each other are partitioned in the width direction over the entire height by a large number of partition plates. The corrugated cardboard plate is not limited to this, and a corrugated plastic plate provided with flat liners on both sides can be used. The plastic flat plate 50 is inserted between the outer fabric 4 b and the corrugated board 5.

側面部３Ｃは、外生地４ｂの上縁に沿って外面に面ファスナー６ａを縫着し、かつ、外生地４ｂの外面に逆Ｕ字形に曲げた布製帯状の持ち手７の両脚部を上記プラスチック平板５０と一体に縫着し、段ボール板５を外生地４ｂと内生地４ａの間に挟み、外生地４ｂと内生地４ａの周縁を重ね合わせ、重ね合わされた周縁をこれを包む布製の縁取りテープ８と一体に縫合することにより形成されている。側面部３Ｃと対向する側面部３Ｄは、側面部３Ｃと同一の構造としてある。 The side surface portion 3C is formed by sewing the surface fastener 6a on the outer surface along the upper edge of the outer fabric 4b, and bending both legs of the cloth-shaped handle 7 bent in an inverted U shape on the outer surface of the outer fabric 4b. Cloth that is sewn together with the flat plate 50, the corrugated board 5 is sandwiched between the outer fabric 4b and the inner fabric 4a, the peripheral edges of the outer fabric 4b and the inner fabric 4a are overlapped, and the overlapped peripheral edges are made of cloth. 8 is formed by sewing together. The side surface portion 3D facing the side surface portion 3C has the same structure as the side surface portion 3C.

長辺側の相対向する側面部３Ａと側面部３Ｂは、内生地４ａと外生地４ｂ間に内設するプラスチック段ボール板５の配置が異なるが、他は同一構造としてある。側面部３Ａについて図１および図３により説明すると、プラスチックダンボール板５は、分割された四角形の二枚の分割板５ａ，５ｂからなる。両分割板５ａ，５ｂは同一高さで、分割板５ａの幅は分割板５ｂの約１．２倍ないし１．３倍としてある。 The side surface portion 3A and the side surface portion 3B facing each other on the long side are different in arrangement of the plastic corrugated board 5 provided between the inner fabric 4a and the outer fabric 4b, but the other structures are the same. The side surface portion 3A will be described with reference to FIGS. 1 and 3. The plastic corrugated board 5 is composed of two divided rectangular divided plates 5a and 5b. Both the dividing plates 5a and 5b have the same height, and the width of the dividing plate 5a is about 1.2 to 1.3 times that of the dividing plate 5b.

側面部３Ａは、分割板５ａ，５ｂを対向する縦縁間に若干の間隔をおいて幅方向に並置し、両面から内生地４ａと、上縁に沿って面ファスナー６ａを縫着した外生地４ｂで挟み、側面部３Ｃ，３Ｄの場合と同様、両生地４ａ，４ｂの周縁を重ね合わせ、重ね合わされた周縁をこれを包む布製の縁取りテープ８と一体に縫合するとともに、内生地４ａと外生地４ｂとを、両分割板５ａ，５ｂの対向縦縁間位置で縦方向直線状に縫着することにより形成されている。この結果、側面部３Ａは、その幅方向中心よりも一方の側（図例では側面部３Ｄ側）に片寄った位置にある両分割板５ａ，５ｂの分割線５１で折り曲げ可能である。 The side portion 3A is an outer fabric in which the divided plates 5a and 5b are juxtaposed in the width direction with a slight gap between the opposing vertical edges, and the inner fabric 4a and the hook-and-loop fastener 6a are sewn along the upper edge from both sides. 4b, as in the case of the side portions 3C and 3D, the peripheral edges of both fabrics 4a and 4b are overlapped, and the overlapped peripheral edges are stitched together with the cloth edging tape 8 that wraps them, and The cloth 4b is formed by sewing in a straight line in the vertical direction at the position between the opposing vertical edges of the two divided plates 5a and 5b. As a result, the side surface portion 3A can be bent at the dividing line 51 of the two divided plates 5a, 5b located at one side (the side surface portion 3D side in the example) from the center in the width direction.

側面部３Ａと対向する側面部３Ｂでは、側面部３Ａにおけると同形同大の分割板５ａ，５ｂが設けてあるが、分割板５ａ，５ｂはその配置が、側面部３Ａとは幅方向逆位置としてある。その他の構造は側面部３Ａと同じである。この結果、側面部３Ｂは、その幅方向中心よりも側面部３Ａにおけるとは逆の側（図例では側面部３Ｃ側）に片寄った位置に分割線５１´で折り曲げ可能である。 In the side surface portion 3B facing the side surface portion 3A, split plates 5a and 5b having the same shape and size as in the side surface portion 3A are provided. However, the arrangement of the split plates 5a and 5b is opposite to the side surface portion 3A in the width direction. As a position. Other structures are the same as those of the side surface portion 3A. As a result, the side surface portion 3B can be bent at the parting line 51 'at a position that is offset from the center in the width direction to the side opposite to the side surface portion 3A (in the illustrated example, the side surface portion 3C side).

上記側面部３Ａ，３Ｃ，３Ｂ，３Ｄは縁取りテープ８により縁取りされた相隣れる縦縁を重ね合わせて縫着してある（図３（Ｂ）参照）、 The side portions 3A, 3C, 3B, 3D are sewn with overlapping vertical edges bordered by the border tape 8 (see FIG. 3 (B)).

底面部１は一枚の布からなり、周縁は縁取りテープ８により縁取りしてある。そして周縁の縁取りテープ８を、側面部３Ａ，３Ｂ，３Ｃ，３Ｄの下縁の縁取りテープ８と重ね合わせて縫着し（図２（Ａ）、図３（Ａ）参照）、側面部３Ａ，３Ｂ，３Ｃと一体化され、長方形状の容器体が形成されている。 The bottom surface portion 1 is made of a single piece of cloth, and the peripheral edge is edged by an edge tape 8. Then, the peripheral edge tape 8 is overlapped with the edge tape 8 on the lower edge of the side surfaces 3A, 3B, 3C, 3D and sewn (see FIGS. 2A and 3A), and the side surfaces 3A, 3A, It is integrated with 3B and 3C, and the rectangular container body is formed.

矩形の側面部上縁のうち、側面部３Ｂの上縁には蓋部２の一辺が接続せしめてある。一枚の布からなる矩形の蓋部２本体の周縁は縁取りテープ８で縁取りしてあり、縁取りされた一辺と、同じく縁取りされた側面部３Ｂの上縁とを重ね合わせ縫合されている。 One side of the lid portion 2 is connected to the upper edge of the side surface portion 3B among the upper edge of the rectangular side surface portion. The peripheral edge of the rectangular lid 2 main body made of a piece of cloth is edged with an edge tape 8, and the edge of the edge and the upper edge of the edged side face 3B are overlapped and stitched.

蓋部２本体の三辺には蓋垂れ２０が取付けてある。図１および図４に示すように、蓋垂れ２０は帯状の布で外周が縁取りテープ８で縁取りがしてあり、蓋体２本体の縁取りされた三辺と、各縁垂れ２０の縁取りされた側縁とを重ね合わせて縫着してある。各蓋垂れ２０の一方の面には面ファスナー６ｂが縫着してある。 A lid sag 20 is attached to three sides of the lid 2 main body. As shown in FIGS. 1 and 4, the lid sag 20 is a belt-like cloth and the outer periphery is trimmed by the edging tape 8, and the three sides of the lid 2 main body are trimmed, and each sag 20 is trimmed. It is sewn with overlapping side edges. A hook-and-loop fastener 6b is sewn on one surface of each lid sag 20.

以上のように構成した通い箱において、荷物、例えば紙類や書物類の収納に際しては、荷物を箱内に積載収納し、蓋体２を閉じ、蓋垂れ２０の面ファスナー６ｂを側面部３Ａ，３Ｃ，３Ｄの面ファスナー６ａに係着せしめる。そして荷物を収納した通い箱を持ち手７により持ち上げて搬送する。 In the returnable box configured as described above, when storing luggage such as paper or books, the luggage is loaded and stored in the box, the lid body 2 is closed, and the hook-and-loop fastener 6b of the lid hanging 20 is attached to the side surface portion 3A, It is attached to the 3C, 3D hook-and-loop fastener 6a. Then, the return box containing the luggage is lifted by the handle 7 and conveyed.

なお図例の通い箱では荷物を収納して搬送する過程で蓋垂れ２０に何らかの外物が引っ掛かって面ファスナー６ａ，６ｂがはずれても開蓋しないように、左右両側の蓋垂れ２０の蓋体自由端側の端部と、閉蓋時に上記端部と対向する側面部３Ｃ，３Ｄの端部に係脱可能なひねりホック６０を設けている。ひねりホック６０は側面部３Ｃ，３Ｄ側に回転かつ起倒可能なひねり部を設けるとともに蓋垂れ２０側にひねり部を挿入する穴を設け、閉蓋時に上記穴に挿入したひねり部を回転させて穴から抜けないようにした状態で倒すものである。 In the illustrated box, the lids of the lid hangings 20 on both the left and right sides do not open even if the hook-and-loop fasteners 6a and 6b come off due to some foreign matter caught in the lid hanging 20 in the process of storing and transporting the luggage. A detachable twist hook 60 is provided at the end portion on the free end side and the end portions of the side surface portions 3C and 3D facing the end portion when the lid is closed. The twist hook 60 is provided with a twistable portion that can be rotated and tilted on the side surfaces 3C and 3D, and a hole for inserting the twisted portion on the lid drooping 20 side, and the twisted portion inserted into the hole is rotated when the lid is closed. Defeat it while keeping it from coming out of the hole.

図５は空箱の折りたたみ態様を模式的に示すもので、（図においてプラスチック板および持ち手の記載は省略した）先ず蓋部２を、側面部３Ｂの上縁に接続する基端縁を中心に回動させて側面部３Ｂの外面に重ね合わせる（図５（Ａ））。次に側面部３Ａと、蓋部２が重ね合わされた側面部３Ｂとを対向方向に押し込むと、両側面部３Ａ，３Ｂはそれぞれ分割線５１，５１´で折りたたまれて断面Ｖ字形状となる（図５（Ｂ））。この場合、蓋部２および底面部１は変形自在な布のみで形成されているから側面部３Ａ，３Ｂの折りたたみの抵抗とはならない。側面部３Ａ，３Ｂの分割線５１，５１´は側面３Ａ，３Ｂの幅方向にずらした位置としてあるから、互いにぶつかり合うことはない。最後に側面部３Ｃ，３Ｄを対向方向に押すことで箱全体がほぼ平板状に折りたたまれる（図５（Ｃ））。 FIG. 5 schematically shows the folding state of the empty box. (In the figure, the description of the plastic plate and the handle is omitted) First, the lid 2 is centered on the base edge that connects the upper edge of the side surface 3B. To overlap the outer surface of the side surface portion 3B (FIG. 5A). Next, when the side surface portion 3A and the side surface portion 3B on which the lid portion 2 is overlapped are pushed in the opposite direction, the both side surface portions 3A and 3B are folded at the dividing lines 51 and 51 ', respectively, to form a V-shaped cross section (see FIG. 5 (B)). In this case, the lid portion 2 and the bottom surface portion 1 are formed of only a deformable cloth, and therefore do not serve as folding resistance of the side surface portions 3A and 3B. Since the dividing lines 51 and 51 ′ of the side surfaces 3A and 3B are shifted in the width direction of the side surfaces 3A and 3B, they do not collide with each other. Finally, the entire box is folded into a substantially flat plate shape by pushing the side surface portions 3C and 3D in the opposite direction (FIG. 5C).

このように折りたたみは極めて簡易な作業でなされ得る。そして折りたたまれた箱の平面の横幅は、短辺側の側面３Ｃ，３Ｄの幅よりも若干長いだけであり、縦幅は側面３Ｃ，３Ｄの幅とほぼ同じであるから、平面積は箱を上下に折りたたんだ場合の平面積、即ち底面部１および蓋部２の平面積よりも小さくなる。また箱は布とプラスチック板の組合せにより構成されているから、全体がプラスチック板で構成された箱よりも軽量である。また側面部３Ａ，３Ｂの分割線５１，５１´は縦方向に設定されているから荷物を収納した箱を重ね乗せしても分割線５１，５１´で折りたたまれることはない。 In this way, folding can be done with a very simple operation. And the width of the plane of the folded box is only slightly longer than the width of the side surfaces 3C and 3D on the short side, and the vertical width is almost the same as the width of the side surfaces 3C and 3D. The flat area when folded up and down, that is, the flat area of the bottom surface portion 1 and the lid portion 2 is smaller. Further, since the box is composed of a combination of cloth and a plastic plate, the whole is lighter than a box composed of a plastic plate. Further, since the dividing lines 51 and 51 ′ of the side surfaces 3 A and 3 B are set in the vertical direction, they are not folded by the dividing lines 51 and 51 ′ even when the boxes storing the luggage are stacked.

上記実施形態は本発明を長方形状の直方体の通い箱に適用したものであるが、平面正方形の直方体の通い箱の場合には、相対向する側面部の分割線をともに側面幅方向の中心位置に設定することができる。このようにしても折りたたみ時にぶつかり合いは生じない。 In the above embodiment, the present invention is applied to a rectangular rectangular parallelepiped return box. However, in the case of a plane square rectangular parallelepiped return box, the dividing line of the opposite side portions is centered in the side width direction. Can be set to Even if it does in this way, collision does not arise at the time of folding.

なお、上記実施形態ではプラスチック板としてプラスチックダンボール板を用いたが、箱の重ね乗せに耐え得る厚さの平板を用いてもよい。また上記実施形態では、蓋閉じ時の蓋部の側面部への係着手段として面ファスナーを用いたが、これに限らず、ホックやチャック式ファスナー等が用いられ得る。 In the above embodiment, a plastic corrugated cardboard plate is used as the plastic plate, but a flat plate having a thickness that can withstand the stacking of boxes may be used. Moreover, in the said embodiment, although the hook_and_loop | surface fastener was used as an engaging means to the side part of a cover part at the time of a cover closing, not only this but a hook, a chuck type fastener, etc. can be used.
