Description

本発明は、種々の物品（食品、部品や製品など）が収容されて保管・搬送される折り畳み式コンテナに関する。特には、蓋とコンテナ本体との間の密閉性、さらには、側板相互間の密閉性を高めたコンテナに関する。   The present invention relates to a foldable container in which various articles (food, parts, products, etc.) are stored, stored and transported. In particular, the present invention relates to a container having improved sealing between the lid and the container body, and further, sealing between the side plates.

折り畳み式コンテナには、長方形の底板と、底板の各対向する辺（長辺・短辺）に起立転倒自在に連結された一対の第１側板及び第２側板を備えるものがある（例えば、特許文献１参照）。組み立てるには、まず第１側板を回動させて起立させ、その後で第２側板を回動させて起立させ、起立した両側板をロックする。この際、起立した両側板の上端面の高さが異なると、蓋の下面と側板の上面との間にスキマが開き、コンテナの密閉性が悪くなる。また、コンテナ本体のみを積み重ねる際に、上側に積み重ねられるコンテナ本体の安定性が悪くなることもある。   Some foldable containers include a rectangular bottom plate and a pair of first and second side plates connected to each opposite side (long side / short side) of the bottom plate so as to be able to stand upside down (for example, patents) Reference 1). To assemble, first, the first side plate is rotated and raised, and then the second side plate is rotated and raised, and the raised side plates are locked. At this time, if the heights of the upper end surfaces of the standing side plates are different, a gap is opened between the lower surface of the lid and the upper surface of the side plate, and the sealing performance of the container is deteriorated. In addition, when only the container main body is stacked, the stability of the container main body stacked on the upper side may be deteriorated.

特開２００８−２８５１８５JP2008-285185A

本発明は上記の問題点に鑑みてなされたものであって、密閉性が良好な、すなわち、起立した側板の上端面の高さに差が生じない折り畳み式コンテナを提供することを目的とする。   The present invention has been made in view of the above problems, and an object thereof is to provide a foldable container having good sealing performance, that is, no difference in the height of the upper end surface of the standing side plate. .

本発明のベースとなる折り畳み式コンテナは、 物品収容凹所を形成する底及び側壁を有するコンテナ本体、並びに、該コンテナ本体の凹所を閉じる蓋、を備えるコンテナであって、 前記側壁は、 前記底板の一方の対向する辺に起立転倒自在に連結された一対の第１側板と、 前記底板の他方の対向する辺に起立転倒可能に連結された一対の第２側板と、 前記第１側板と前記第２側板とを隅部で接続する接続手段と、を具備し、 前記接続手段が、 前記第１側板の端部内面から内側（前記凹所側）に突き出す突片と、 前記第２側板の端部に形成された切欠きと、からなり、 前記第１側板又は第２側板を起立させた後で前記第２側板又は第１側板を起立させる際に、前記突片が前記切欠きに係合して、前記第１側板の上端面と第２側板の上端面とが面一となることを特徴とする。 A foldable container serving as a base of the present invention is a container including a container main body having a bottom and a side wall forming an article receiving recess, and a lid for closing the recess of the container main body, wherein the side wall includes: A pair of first side plates connected to one opposite side of the bottom plate so as to be able to stand upside down; a pair of second side plates connected to the other opposite side of the bottom plate so as to be able to stand upside down; and the first side plate; Connecting means for connecting the second side plate with a corner portion, wherein the connecting means protrudes inwardly from the inner surface of the end portion of the first side plate (the recess side), and the second side plate A notch formed at an end of the first side plate, and when the second side plate or the first side plate is erected after the first side plate or the second side plate is erected, the projecting piece becomes the notch. Engage and the upper end surface of the first side plate and the upper end surface of the second side plate There characterized by comprising a flush.

突片と切欠きを係合させることにより、起立した側板同士を高さ方向・横方向において密に接続できる。この際、突片と切欠きとの位置や寸法を厳密に合わせておくことにより、第１側板と第２側板の上面を極力一致させることができ、蓋の下面とコンテナ本体の上面とのスキマをなくし、蓋とコンテナ本体間の密閉性が得られる。さらに、側板相互間の密閉性が得られ、コンテナ本体の強度を向上させることができる。   By engaging the protruding piece and the notch, the standing side plates can be closely connected in the height direction and the horizontal direction. At this time, the upper surface of the first side plate and the second side plate can be matched as much as possible by precisely matching the positions and dimensions of the projecting piece and the notch, and the gap between the lower surface of the lid and the upper surface of the container body can be assured. The sealing between the lid and the container body can be obtained. Furthermore, the sealing property between the side plates can be obtained, and the strength of the container body can be improved.

なお、突片と切欠きは、できるだけ側板の高い位置に設けることが好ましい。突片と切欠きと側板上面との間の寸法が短い方が、その寸法の製造公差を小さくでき、両側板上面の面一性が良くなる。   In addition, it is preferable to provide the projecting piece and the notch as high as possible on the side plate. A shorter dimension between the projecting piece, the notch and the upper surface of the side plate can reduce the manufacturing tolerance of the size, and the surface uniformity of the upper surfaces of both side plates is improved.

本発明においては、 前記突片と切欠きとがテーパ状に形成されており、該突片と切欠きとの係合時の楔効果により、前記両側板が接近する方向に引き寄せられて固定されるので、側板間の接続強度が高められ、側板相互間の密閉性が得られるとともに、コンテナ本体の強度をより向上できる。 In the present invention, the projecting piece and the notch are formed in a tapered shape, and the both side plates are attracted and fixed in the approaching direction by a wedge effect when the projecting piece and the notch are engaged. since that, the connection strength between the side plates is enhanced, with sealing of the side plates cross is obtained, it is possible to further improve the strength of the container body.

前記接続手段の具体的な構造としては、 前記突片が、前記第１側板の内面に突設された基部と、該基部から上下方向に張り出した張出部と、を有し、 前記切欠きが、あり溝と、該あり溝の側方において張り出したフランジ部と、を有し、 前記突片と前記切欠きとの係合時には、前記突片の張出部が前記切欠きのあり溝に入り込み、前記突片の基部が前記切欠きのフランジ部に係合することとできる。
「あり溝」とは、二つの部材に、溝とそれにスライドして入る凸部が形成されており、溝は底広、凸部は頭広となっており、スライド方向と異なる方向には２部材が分離しないような溝をいう。 As a specific structure of the connecting means, the projecting piece has a base part projecting from the inner surface of the first side plate, and an overhang part projecting vertically from the base part, and the notch Has a dovetail groove and a flange portion projecting on the side of the dovetail groove, and when the projecting piece and the notch are engaged, the projecting portion of the projecting piece is the notched groove. The base of the protruding piece can be engaged with the flange portion of the notch.
A “groove” is a groove formed on two members and a convex portion that slides into the two members. The groove is wide at the bottom, and the convex portion is wide at the head. A groove that does not separate the members.

この場合、 前記突片の基部及び張出部の上下端面がテーパ面であり、該上下端面間の間隔が内方向に向かって先細であり、 前記切欠きのあり溝及びフランジ部の上下端面がテーパ面であり、該上下端面間の間隔が内方向に向かって先細であることが好ましい。   In this case, the upper and lower end surfaces of the base portion and the overhanging portion of the projecting piece are tapered surfaces, the interval between the upper and lower end surfaces is tapered inwardly, and the upper and lower end surfaces of the notched groove and the flange portion are It is a taper surface, and it is preferable that the space | interval between this upper-lower-end surface is tapering inward.

さらには、 前記突片の張出部の厚さが、内方向に向かって先細となっており、 前記切欠きのあり溝の幅が内方向に向かって先細であることが好ましい。   Furthermore, it is preferable that the thickness of the protruding portion of the protruding piece is tapered inward, and the width of the groove with the notch is tapered inward.

本発明においては、 前記短側板と前記長側板とに、該両側板を起立状態でロックするロック機構が設けられていることが好ましい。   In the present invention, it is preferable that the short side plate and the long side plate are provided with a lock mechanism that locks the both side plates in an upright state.

この場合、 前記ロック機構が、 前記短側板に取り付けられた、バネ機構により外方向（該短側板の幅方向における外方向）に付勢されるロック部を有するロック部材と、 前記長側板に設けられた、前記ロック部材のロック部が係合する突起と、を有し、 起立した前記長側板に対して前記短側板を回動させると、前記ロック部材のロック部が、前記バネ機構の収縮により前記突起を超えた後外方向に付勢されて前記突起に係合し、これにより起立した前記長側板と短側板とがロックされ、 前記バネ機構を収縮させることにより、前記ロック部材のロック部が前記突起から外れて、起立した前記長側板と短側板とのロックが解除されることとできる。   In this case, the lock mechanism includes a lock member attached to the short side plate and having a lock portion that is urged outward (outward in the width direction of the short side plate) by a spring mechanism; A protrusion that engages with the lock portion of the lock member, and when the short side plate is rotated with respect to the upstanding long side plate, the lock portion of the lock member contracts the spring mechanism. After the projection exceeds the projection, it is urged outward and engaged with the projection, whereby the standing long plate and the short plate are locked, and the spring mechanism is contracted to lock the locking member. The part is detached from the protrusion, and the lock between the standing long side plate and the short side plate can be released.

このようなロック機構を設けた場合、 前記側板を起立させる際に前記接続機構の突片と切欠きとが係合し始めて、前記両側板が離間し得なくなった状態の後に、前記ロック機構が作動し始めることとすれば、ロック部材を確実に突起に係合させることができる。   When such a locking mechanism is provided, after the side plate is raised, the locking mechanism begins to engage with the protruding piece and the notch and the both side plates cannot be separated. If it starts to operate | move, a locking member can be reliably engaged with protrusion.

以上の説明から明らかなように、本発明によれば、起立時に側板同士が接近する方向に引き寄せられて接続されるので、側壁相互間の密閉性が高められる。この際、突片と切欠きとの位置や寸法を厳密に合わせておくことにより、第１側板と第２側板の上面を一致させることができ、蓋の下面とコンテナ本体の上面とのスキマをなくし、コンテナの密閉性を得られる。   As is clear from the above description, according to the present invention, the side plates are attracted and connected in the direction in which the side plates approach each other at the time of standing, and thus the sealing property between the side walls is improved. At this time, the upper surface of the first side plate and the second side plate can be made to coincide with each other by precisely matching the positions and dimensions of the projecting piece and the notch, and the clearance between the lower surface of the lid and the upper surface of the container body can be reduced. Eliminates the container sealing performance.

以下、本発明の実施の形態について、図面を参照しながら詳細に説明する。
コンテナ１は、図１に示すように、物品収容凹所２（図３参照）を形成する底と側壁を有するコンテナ本体２０と、コンテナ本体２０の凹所２を閉じる蓋１０を備える。以降の説明において、凹所２の側を内側（内方向）、その反対側を外側（外方向）という。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the container 1 includes a container body 20 having a bottom and a side wall that forms an article housing recess 2 (see FIG. 3), and a lid 10 that closes the recess 2 of the container body 20. In the following description, the side of the recess 2 is referred to as the inside (inward direction), and the opposite side is referred to as the outside (outward direction).

まず、蓋１０の構造を説明する。
図２に示すように、蓋１０は、平面形状が長方形で、所定の厚さを有する。蓋１０の上面には、外縁に沿って高さの低い土手部１１が形成されている。コンテナ積み重ね時、あるいは、蓋単体の積み重ね時には、この土手部１１で囲まれた凹部内に、上に積み重ねられるコンテナ本体の下面に形成された下凸部、あるいは、蓋１０の下面に形成された下凸部１５（詳細後述）が嵌り込み、積み重ね時の安定を与える。また、土手部１１の長辺の所定位置には凹部１２が形成されており、この凹部１２に、コンテナ本体２０に蓋１０をしたときに、蓋１０をコンテナ本体２０に留める留め部材１３が取り付けられている。留め部材１３には、弾性変形する係止片が設けられており、この係止片がコンテナ本体２０に係止される。なお、この留め部材１３は、折り畳んだコンテナ本体２０に蓋１０をしたときにも、蓋１０とコンテナ本体２０とを係止する。この例では、留め部材１３は各長辺に２個ずつ取り付けられている。 First, the structure of the lid 10 will be described.
As shown in FIG. 2, the lid 10 has a rectangular planar shape and a predetermined thickness. On the upper surface of the lid 10, a bank portion 11 having a low height is formed along the outer edge. When stacking containers, or when stacking lids alone, they are formed in the recesses surrounded by the bank portion 11, on the lower projections formed on the lower surface of the container body stacked on top, or on the lower surface of the lid 10. The lower convex part 15 (detailed later) fits in and provides stability during stacking. A concave portion 12 is formed at a predetermined position on the long side of the bank portion 11, and a fastening member 13 for attaching the lid 10 to the container body 20 when the lid 10 is attached to the container body 20 is attached to the concave portion 12. It has been. The fastening member 13 is provided with a locking piece that is elastically deformed. The locking piece is locked to the container body 20. The fastening member 13 locks the lid 10 and the container body 20 even when the lid 10 is placed on the folded container body 20. In this example, two fastening members 13 are attached to each long side.

図２（Ｂ）に示すように、蓋１０の下面には、蓋１０の輪郭よりも一回り小さい輪郭の、下方に突出する下凸部１５が形成されている。   As shown in FIG. 2B, a lower convex portion 15 is formed on the lower surface of the lid 10. The lower convex portion 15 has a contour that is slightly smaller than the contour of the lid 10 and projects downward.

次に、図３〜図８を参照してコンテナ本体２０を説明する。
コンテナ本体２０は、図３、図４に示すように、底を構成する平面形状が長方形の底板３０と、側壁を構成する一対の短側板４０及び一対の長側板６０と、からなる。短側板４０及び長側板６０は、底板３０に折り畳み可能に連結している。コンテナ本体２０を折り畳む際は、まず、図４に示すように、短側板４０を内側に折り畳み、その後、長側板６０を、折り畳まれた短側板４０に重ねるように折り畳む。さらに、コンテナ本体２０には、起立した短側板４０と長側板６０とを、コンテナ本体２０の隅で接続する接続機構３００（詳細は図６、８、９を参照しつつ後述する）を備える。さらに、起立した短側板４０と長側板６０とをロックするロック機構４００を備えることもできる（詳細は図５〜９を参照しつつ後述する）。 Next, the container body 20 will be described with reference to FIGS.
As shown in FIGS. 3 and 4, the container body 20 includes a bottom plate 30 having a rectangular planar shape constituting a bottom, a pair of short side plates 40 and a pair of long side plates 60 constituting side walls. The short side plate 40 and the long side plate 60 are connected to the bottom plate 30 so as to be foldable. When the container body 20 is folded, first, as shown in FIG. 4, the short side plate 40 is folded inward, and then the long side plate 60 is folded so as to overlap the folded short side plate 40. Furthermore, the container main body 20 includes a connection mechanism 300 (details will be described later with reference to FIGS. 6, 8, and 9) that connect the short side plate 40 and the long side plate 60 that stand up at the corner of the container main body 20. Furthermore, the locking mechanism 400 which locks the standing short side board 40 and the long side board 60 can also be provided (details are mentioned later, referring FIGS. 5-9).

底板３０について、図３、図４を参照して説明する。
底板３０は、図３、図４に示すように、平面形状が長方形の底部３１と、底部３１の上面周囲から立ち上がった周壁部３２とを有する。各短辺側周壁部３２Ｓには、短側板４０が起倒自在に連結され、各長辺側周壁部３２Ｌには、長側板６０が起倒自在に連結されている。なお、短辺側周壁部３２Ｓの高さは、長辺側周壁部３２Ｌよりもが低くなっている。これは、コンテナ本体２０を折り畳む際に、先に短側板４０を折り畳み、折り畳まれた短側板４０の上に長側板６０を折り畳むためである。 The bottom plate 30 will be described with reference to FIGS.
As shown in FIGS. 3 and 4, the bottom plate 30 includes a bottom portion 31 having a rectangular planar shape and a peripheral wall portion 32 rising from the periphery of the upper surface of the bottom portion 31. The short side plate 40 is connected to each short side peripheral wall portion 32S so as to be able to be tilted up and down, and the long side plate 60 is connected to each long side side peripheral wall portion 32L so as to be freely set up and down. In addition, the height of the short side circumferential wall portion 32S is lower than that of the long side circumferential wall portion 32L. This is because when the container body 20 is folded, the short side plate 40 is first folded, and the long side plate 60 is folded on the folded short side plate 40.

短側板４０について、図５、図６を主に参照して説明する。
短側板４０は、図５に示すように、平面形状が略長方形の、ある程度の厚さを有する部材であり、幅は、底板３０の短辺側周壁部３２Ｓの長さよりも、長側板６０の厚さの２倍程度短くなっている。これは、折り畳み時に、側板の厚さによる側板同士の干渉を避けるためである。 The short side plate 40 will be described with reference mainly to FIGS. 5 and 6.
As shown in FIG. 5, the short side plate 40 is a member having a certain thickness with a planar shape being substantially rectangular, and the width is larger than the length of the short side peripheral wall portion 32 </ b> S of the bottom plate 30. It is about twice as short as the thickness. This is to avoid interference between the side plates due to the thickness of the side plates during folding.

図６（Ａ）の右上側に示すように、短側板４０の上端面４１の内側には、同端面４１よりも一段低い内側端面４２が形成されている。   As shown in the upper right side of FIG. 6A, an inner end face 42 that is one step lower than the end face 41 is formed inside the upper end face 41 of the short side plate 40.

図６を参照して、短側板４０の側部の構造を説明する。図６（Ａ）は、短側板３０の側部を示す斜視図であり、図の紙面奥側の面が凹所２側の面（内側）、紙面手前側の面が反凹所側の面（外側）、右下側の面が側面である。
図６（Ａ）に示すように、短側板４０の外面４０ａと側面４０ｂとの角は切り欠かれた形状となっており、外面４０ａから一段奥側の奥側外面４０ｃと、側面４０ｂから一段奥側の奥側側面４０ｄとが形成されている。さらに、側面４０ｂと奥側外面４０ｃとの角の上部には、ほぼ直角に切り欠かれた形状の上凹部５５が形成されている。この上凹部５５は、短側板４０の外面４０ａに形成された凹部４９と連通しており、後述するように、ロック部材１００のロック部１０４が収容される。 The structure of the side part of the short side plate 40 will be described with reference to FIG. FIG. 6A is a perspective view showing a side portion of the short side plate 30, where the surface on the back side of the drawing is the surface on the recess 2 side (inside), and the surface on the front side of the drawing is the surface on the anti-recess side. (Outside), the lower right surface is the side surface.
As shown in FIG. 6A, the corners of the outer surface 40a and the side surface 40b of the short side plate 40 are notched, and the outer side 40c is one step deeper from the outer surface 40a, and one step is further from the side surface 40b. A back side surface 40d on the back side is formed. Further, an upper concave portion 55 having a shape cut out at a substantially right angle is formed at the upper portion of the corner between the side surface 40b and the rear outer surface 40c. The upper concave portion 55 communicates with a concave portion 49 formed on the outer surface 40a of the short side plate 40, and the lock portion 104 of the lock member 100 is accommodated as will be described later.

上凹部５５の下方には、奥側外面４０ｃと側面４０ｂとの間の角が切り欠かれた切欠き５６が形成されている。この切欠き５６は、短側板４０と長側板６０とをコンテナ本体２０の隅部で接続するためのものである（接続機構３００）。切欠き５６は、奥側外面４０ｃから内方向（凹所方向）に延びるあり溝５７と、あり溝５７の側方において張り出したフランジ部５８と、を有する。   A notch 56 in which a corner between the back outer surface 40c and the side surface 40b is notched is formed below the upper recess 55. This notch 56 is for connecting the short side plate 40 and the long side plate 60 at the corner of the container body 20 (connection mechanism 300). The notch 56 has a dovetail groove 57 that extends inward (in the recess direction) from the back outer surface 40 c and a flange portion 58 that protrudes laterally of the dovetail groove 57.

図６（Ｂ）、（Ｃ）を参照して切欠き５６の形状を詳細に説明する。図６（Ｂ）は切欠きの側面を示し、図６（Ｃ）は切欠きの縦断面を示す。
図６（Ｂ）に示すように、あり溝５７の上下の端面と、フランジ部５８の上下の端面は、端面間の幅が内側に向かうほど狭くなるように傾斜したテーパ面となっている。また、図６（Ｃ）に示すように、あり溝７７の幅は、内側へ向かうほど先細となっている。具体的には、フランジ部５８の短側板奥側側面４０ｄ側の面がテーパ面となっており、フランジ部５８と奥側側面４０ｄ間の間隔が内側へ向かうほど狭くなっている。
なお、テーパ面は、傾斜面とストレートな面、あるいは、面取り・アール面とを組み合わせたものでもよい。 The shape of the notch 56 will be described in detail with reference to FIGS. 6 (B) and 6 (C). 6B shows a side surface of the notch, and FIG. 6C shows a longitudinal section of the notch.
As shown in FIG. 6B, the upper and lower end faces of the dovetail groove 57 and the upper and lower end faces of the flange portion 58 are tapered surfaces that are inclined so that the width between the end faces becomes narrower toward the inside. Further, as shown in FIG. 6C, the width of the dovetail groove 77 tapers toward the inside. Specifically, the surface on the short side plate back side surface 40d side of the flange portion 58 is a tapered surface, and the interval between the flange portion 58 and the back side surface 40d becomes narrower toward the inside.
The tapered surface may be an inclined surface and a straight surface, or a combination of a chamfered and rounded surface.

図５を参照して短側板４０の外面について説明する。短側板４０の外面のほぼ中央には、持ち運び時に指先が入る凹部４８が形成されている。この凹部４８の上方には、ロック部材１００を収容する凹部４９が、短側板４０の幅方向に渡って形成されている。さらに、外面には、上縁から凹部４９に連通する溝部５１が形成されている。この溝部５１は、ロック部材１００を操作する際に指を入り込ませて、ロック部材１００を扱いやすくするためのものである。   The outer surface of the short side plate 40 will be described with reference to FIG. A concave portion 48 into which a fingertip enters during carrying is formed in the approximate center of the outer surface of the short side plate 40. Above this recess 48, a recess 49 that accommodates the lock member 100 is formed across the width of the short side plate 40. Further, a groove 51 that communicates from the upper edge to the recess 49 is formed on the outer surface. The groove 51 is provided to make the finger easy to handle by allowing a finger to enter when operating the lock member 100.

図７を参照してロック部材の構造を説明する。
ロック部材１００は、長尺状のある程度の硬さを有する樹脂成型品であり、長さは、短側板４０の幅とほぼ等しい。ロック部材１００は、図６に示すように、短側板４０の外面の凹部４９にスライド可能に収容されて、取り外し可能なカバー部材５２、５３で保持されている。 The structure of the lock member will be described with reference to FIG.
The lock member 100 is a long resin molded product having a certain degree of hardness, and the length is substantially equal to the width of the short side plate 40. As shown in FIG. 6, the lock member 100 is slidably accommodated in a concave portion 49 on the outer surface of the short side plate 40, and is held by removable cover members 52 and 53.

図７に示すように、ロック部材１００は、中央の波型バネ部１０１と、その両側のリング部１０３と、両端に配置されたロック部１０４と、リング部１０３とロック部１０４とを接続する接続部１０５とを有する。
波型バネ部１０１は、両リング部１０３及びロック部１０４を同バネ部に対して外方向に付勢している。
リング部１０３は、作業時に指を入れて互いに引き寄せて、波型バネ部１０１を圧縮させるためのものである。リング部１０３の内側の縁には、リング部１０３の内方向に張り出す張り出し部１０３ａが形成されている。この張り出し部１０３ａは、操作時に指を引っ掛けやすくするためのものである。さらに、両リング部１０３には、波型バネ部１０１の方向に延びるバネ片１０７が設けられている。これらのバネ片１０７は、リング部１０３を互いに引き寄せたときに下シール部材９０に形成された突起（図示されず）に当接して弾性変形してバネ作用を生じる。 As shown in FIG. 7, the lock member 100 connects the center wave spring portion 101, the ring portions 103 on both sides thereof, the lock portions 104 disposed at both ends, and the ring portion 103 and the lock portion 104. And a connection unit 105.
The wave spring portion 101 urges both the ring portion 103 and the lock portion 104 outward with respect to the spring portion.
The ring portion 103 is for compressing the wave spring 101 by putting fingers together during operation and pulling them together. On the inner edge of the ring portion 103, an overhang portion 103 a that protrudes inward of the ring portion 103 is formed. This overhanging portion 103a is for making it easier to hook a finger during operation. Further, both ring portions 103 are provided with spring pieces 107 extending in the direction of the wave spring portion 101. These spring pieces 107 come into contact with protrusions (not shown) formed on the lower seal member 90 when the ring portions 103 are pulled toward each other, and are elastically deformed to generate a spring action.

ロック部１０４は、略直方体状の形状であり、図７（Ｂ）に示すように、外側の側面は、内から外に向かって広がるテーパ面１０４ａとなっている。図７（Ｂ）に示すように、ロック部１０４は、ロック部材１００のその他の部分と同一直線状ではなく、やや内側をこれらの部分と平行に外方向に延びている。   The lock portion 104 has a substantially rectangular parallelepiped shape, and as shown in FIG. 7B, the outer side surface is a tapered surface 104a that spreads from the inside toward the outside. As shown in FIG. 7B, the lock portion 104 is not collinear with the other portions of the lock member 100, and extends slightly inwardly in parallel to these portions.

各リング部１０３に指を挿入して、両リング部１０３を寄せると、波型バネ部１０１は収縮し、ロック部１０４は内方向に移動する。指を離すと、波型バネ部１０１はもとの形状に戻り、ロック部１０４は外方向へ移動する。   When a finger is inserted into each ring portion 103 and both ring portions 103 are brought close together, the wave spring portion 101 contracts and the lock portion 104 moves inward. When the finger is released, the wave spring 101 returns to its original shape, and the lock 104 moves outward.

次に、長側板６０について、図３、図４、図８を参照して説明する。
長側板６０は、図３、図４に示すように、平面形状が略長方形の、ある程度の厚さを有する部材であり、幅は、底板３０の周壁部３２の長辺３２Ｌの長さと等しい。 Next, the long side plate 60 will be described with reference to FIGS. 3, 4, and 8.
As shown in FIGS. 3 and 4, the long side plate 60 is a member having a certain thickness with a planar shape being substantially rectangular, and the width is equal to the length of the long side 32 </ b> L of the peripheral wall portion 32 of the bottom plate 30.

長側板６０の上端面６１の内側には、同端面６１よりも低い内側端面６２が形成されている。図３に示すように、上端面６１の高さは、短側板４０の上端面４１の高さと同じであり、内側端面６２の高さは、短側板４１の内側端面４２の高さと同じである。   An inner end face 62 lower than the end face 61 is formed inside the upper end face 61 of the long side plate 60. As shown in FIG. 3, the height of the upper end surface 61 is the same as the height of the upper end surface 41 of the short side plate 40, and the height of the inner end surface 62 is the same as the height of the inner end surface 42 of the short side plate 41. .

長側板６０の外面の両側端部には、底板３０の短辺側周壁部３２Ｓに沿ってやや張り出した張り出し部６７が形成されている。また、長側板６０の外面の上端付近には、蓋１０に取り付けられた留め部材１３の係合片が係合する係合凹部７１が形成されている。   At both end portions of the outer surface of the long side plate 60, a protruding portion 67 that slightly protrudes along the short side peripheral wall portion 32S of the bottom plate 30 is formed. In addition, an engagement recess 71 is formed in the vicinity of the upper end of the outer surface of the long side plate 60 to engage with the engagement piece of the fastening member 13 attached to the lid 10.

図８を参照して、長側板６０の側部の構造を説明する。図８（Ａ）は、長側板６０の側部を示す斜視図であり、紙面手前側の面が凹所２側の面（内側）、紙面奥側の面が反凹所側の面（外側）である。
図８に示すように、長側板６０の内面の張り出し部６７の内面６７ａからやや内寄りの位置には、短側板４０に取り付けられたロック部材１００（図７参照）のロック部１０４が係合する突部７３が形成されている。この突部７３とロック部材１００により、短側板４０と長側板６０とがロックされる（詳細は後述する）。突部７３はある程度の高さを有し、内側の側面は、長側板６０の内面から斜め外方向に傾斜した傾斜面７３ａとなっており、外側の側面は、長側板６０の内面にほぼ垂直な垂直面７３ｂとなっている。この垂直面７３ｂと、張り出し部６７の内面６７ａとの間には所定のスキマが開いている。 With reference to FIG. 8, the structure of the side part of the long side board 60 is demonstrated. FIG. 8A is a perspective view showing a side portion of the long side plate 60, where the front surface of the paper surface is the surface on the recess 2 side (inside), and the back surface of the paper surface is the surface on the anti-recess side (outside). ).
As shown in FIG. 8, the lock portion 104 of the lock member 100 (see FIG. 7) attached to the short side plate 40 is engaged at a position slightly inward from the inner surface 67a of the overhang portion 67 of the inner surface of the long side plate 60. A protruding portion 73 is formed. The short side plate 40 and the long side plate 60 are locked by the protrusion 73 and the lock member 100 (details will be described later). The protrusion 73 has a certain height, the inner side surface is an inclined surface 73 a inclined obliquely outward from the inner surface of the long side plate 60, and the outer side surface is substantially perpendicular to the inner surface of the long side plate 60. This is a vertical surface 73b. A predetermined gap is opened between the vertical surface 73 b and the inner surface 67 a of the overhanging portion 67.

突部７３の下方には、前述した短側板４０に形成した切欠き５６に係合する突片７５が立設されている。この突片７５と、短側板４０の側部に形成した切欠き５６により、短側板４０と長側板６０とがコンテナ本体２０の隅部で接続される。突片７５は、長側板６０の内面に突設された平面形状が長方形状の基部７６と、基部７６の上面から長側板の上下方向に張り出した張出部７７とを有する。この突片７６は、長側板６０に取り外し可能に取り付けられる樹脂成型品７８に一体に形成されている。   Below the protrusion 73, a protrusion 75 that is engaged with the notch 56 formed in the short side plate 40 is provided upright. The short side plate 40 and the long side plate 60 are connected to each other at the corner of the container body 20 by the protruding piece 75 and a notch 56 formed on the side portion of the short side plate 40. The projecting piece 75 includes a base portion 76 having a rectangular planar shape protruding from the inner surface of the long side plate 60, and an overhang portion 77 projecting from the upper surface of the base portion 76 in the vertical direction of the long side plate. The projecting piece 76 is integrally formed with a resin molded product 78 that is detachably attached to the long side plate 60.

図８（Ｂ）、（Ｃ）を参照して突片７５の形状を詳細に説明する。図８（Ｂ）は突片の側面を示し、図８（Ｃ）は突片の縦断面を示す。
図８（Ｂ）に示すように、基部７６の上下の端面と張出部７７の上下の端面は、端面間の幅が内側に向かうほど狭くなるように傾斜したテーパ面となっている。また、図８（Ｃ）に示すように、張出部７７の厚さは、内側に向かうほど狭くなっている。具体的には、張出部７７の長側板６０の内面６０ａ側の面がテーパ面となっており、張出部７７と長側板内面６０ａ間の間隔が外側へ向かうほど狭くなっている。 The shape of the protrusion 75 will be described in detail with reference to FIGS. FIG. 8B shows a side surface of the projecting piece, and FIG. 8C shows a longitudinal section of the projecting piece.
As shown in FIG. 8B, the upper and lower end surfaces of the base portion 76 and the upper and lower end surfaces of the overhang portion 77 are tapered surfaces that are inclined so that the width between the end surfaces becomes narrower toward the inside. Further, as shown in FIG. 8C, the thickness of the overhanging portion 77 becomes narrower toward the inside. Specifically, the surface on the inner surface 60a side of the long side plate 60 of the overhanging portion 77 is a tapered surface, and the interval between the overhanging portion 77 and the long side plate inner surface 60a becomes narrower toward the outside.

次に、図９、図１０を参照して、組み立て時の短側板４０と長側板６０との接続機構３００、及び、両側板のロック機構４００を説明する。
コンテナ本体２０を組み立てる際は、まず長側板６０を回動して起立させる。その後、図９（Ａ）に示すように、短側板４０を回動する。すると、まず、図９（Ｂ）に示すように、短側板４０の切欠き５６に長側板６０の突片７５が係合し始める。すると、側板同士が離間し得なくなる。この状態となった後に、短側板４０のロック部材１００のロック部１０４が、長側板６０の内面に形成された突部７３に達し、ロック部材１００のロック部１０４のテーパ面１０４ａが突部７３のテーパ面７３ａに沿って乗り上げ始める。これにより、ロック部１０４が内方向に押される。ロック部材１００の姿勢は保持されているので、このロック部１０４の内方向への移動は、波型バネ部１０１の収縮により吸収される。 Next, the connection mechanism 300 between the short side plate 40 and the long side plate 60 and the locking mechanism 400 for both side plates will be described with reference to FIGS.
When assembling the container main body 20, first, the long side plate 60 is turned upright. Thereafter, as shown in FIG. 9A, the short side plate 40 is rotated. Then, first, as shown in FIG. 9B, the protruding piece 75 of the long side plate 60 starts to engage with the notch 56 of the short side plate 40. Then, the side plates cannot be separated from each other. After this state is reached, the lock portion 104 of the lock member 100 of the short side plate 40 reaches the protrusion 73 formed on the inner surface of the long side plate 60, and the taper surface 104 a of the lock portion 104 of the lock member 100 is the protrusion 73. Ride along the tapered surface 73a. As a result, the lock unit 104 is pushed inward. Since the posture of the lock member 100 is maintained, the inward movement of the lock portion 104 is absorbed by the contraction of the wave spring portion 101.

さらに短側板４０を回動させると、図９（Ｃ）に示すように、短側板４０の切欠き５６に長側板６０の突片７５が完全に係合する。詳細に説明すると、図１０（Ｂ）、（Ｃ）に示すように、突片７５の張出部７７が、切欠き５６のあり溝５７に嵌り込み、基部７６が両フランジ部５８の間に嵌り込む。言い換えれば、短側板４０のフランジ部５８は、長側板６０の内面６０ａと突片７５の張出部７７との間に挟み込まれる。   When the short side plate 40 is further rotated, the projecting piece 75 of the long side plate 60 is completely engaged with the notch 56 of the short side plate 40 as shown in FIG. More specifically, as shown in FIGS. 10B and 10C, the projecting portion 77 of the projecting piece 75 fits into the groove 57 of the notch 56, and the base portion 76 is between the flange portions 58. Fit. In other words, the flange portion 58 of the short side plate 40 is sandwiched between the inner surface 60 a of the long side plate 60 and the protruding portion 77 of the protruding piece 75.

突片７５と切欠き５６との係合面は、前述のようにテーパ面となっているので、両者が係合すると、楔効果により両側板４０、６０は互いに引き寄せられる。これにより、両側板は高さ方向にも横方向にもガタつかないように接続される。さらに、突片７５と切欠き５６の位置や寸法を厳密に合わせておくことにより、接続された短側板４０と長側板６０の上端面４１、６１、及び、内側端面４２、６２を同一面に合わせることができる。この場合、上端面４１、６１間、及び、内側端面４２、６２間に段差がないので、蓋１０と、内側端面４２、６２、及び、上端面４１、６１との間にスキマが生じず、密閉性が得られる。
なお、突片７５と切欠き５６は、できるだけ側板６０、４０の高い位置に設けることが好ましい。突片７５と切欠き５６と側板６０、４０上端面６１、４１との間の寸法が短い方が、その寸法の製造公差を小さくでき、両側板４０、６０の上端面６１、４１の面一性が良くなる。 Since the engaging surface of the projecting piece 75 and the notch 56 is a tapered surface as described above, the both side plates 40 and 60 are attracted to each other by the wedge effect when they are engaged. Thereby, both side plates are connected so as not to rattle both in the height direction and in the lateral direction. Furthermore, the upper end surfaces 41 and 61 and the inner end surfaces 42 and 62 of the connected short side plate 40 and the long side plate 60 are made to be the same surface by precisely matching the positions and dimensions of the projecting piece 75 and the notch 56. Can be matched. In this case, since there is no step between the upper end surfaces 41 and 61 and between the inner end surfaces 42 and 62, there is no gap between the lid 10 and the inner end surfaces 42 and 62 and the upper end surfaces 41 and 61. Sealability is obtained.
In addition, it is preferable to provide the protruding piece 75 and the notch 56 as high as possible on the side plates 60 and 40. The shorter the dimension between the projecting piece 75, the notch 56 and the side plates 60, 40, the upper end surfaces 61, 41 can reduce the manufacturing tolerance of the size, and the upper end surfaces 61, 41 of the side plates 40, 60 are flush with each other. Sexuality is improved.

両側板４０、６０が起立した状態においては、図１０（Ａ）に示すように、長側板６０の内面６０ａに短側板４０の側面４０ｂが当接する。そして、長側板６０の張り出し部６７の端面６７ｂに短側板４０の奥側側面４０ｄが当接し、内面６７ａに奥側外面４０ｃが当接する。   In a state where the side plates 40 and 60 are erected, the side surface 40b of the short side plate 40 comes into contact with the inner surface 60a of the long side plate 60 as shown in FIG. Then, the back side surface 40d of the short side plate 40 abuts on the end surface 67b of the protruding portion 67 of the long side plate 60, and the back side outer surface 40c abuts on the inner surface 67a.

そして、短側板４０の奥側外面４０ｃが長側板６０の張り出し部６７に当接するとともに、ロック部材１００のロック部１０４が突部７３から離れて、波型バネ部１０１により外方向に付勢され、突部７３の垂直面７３ｂと長側板６０の張り出し部６７との間に嵌り込む。これにより、短側板４０と長側板６０が起立状態でロックされる。このように、起立した長側板６０に対して短側板４０を回動させるだけで起立した両側板６０、４０をロックできる。   The back side outer surface 40c of the short side plate 40 abuts on the protruding portion 67 of the long side plate 60, and the lock portion 104 of the lock member 100 is separated from the projection 73 and is urged outward by the corrugated spring portion 101. The projection 73 is fitted between the vertical surface 73 b of the protrusion 73 and the overhanging portion 67 of the long side plate 60. Thereby, the short side plate 40 and the long side plate 60 are locked in the standing state. In this manner, the standing side plates 60 and 40 can be locked only by rotating the short side plate 40 with respect to the standing long side plate 60.

一方、折り畳み時は、ロック部材１００の両リング部１０３を中央に寄せる。この際、指を短側板４０の外面に形成した溝部５１に沿わせると、リング部１０３をつかみやすい。すると、ロック部１０４が、長側板６０の突部７３と張り出し部６７との間から抜け出し、ロックが解除される。このように、ワンタッチ式でロック機構４００を解除できる。その後、短側板４０が長側板６０の突部７３を過ぎるまで両リング部１０３を中央に寄せたまま短側板４０を倒せばよい。   On the other hand, at the time of folding, both the ring portions 103 of the lock member 100 are moved to the center. At this time, if the finger is placed along the groove 51 formed on the outer surface of the short side plate 40, the ring portion 103 is easily grasped. Then, the lock part 104 comes out from between the protrusion 73 and the overhang | projection part 67 of the long side board 60, and a lock | rock is cancelled | released. In this way, the lock mechanism 400 can be released with a one-touch type. Thereafter, the short side plate 40 may be tilted while the ring portions 103 are moved to the center until the short side plate 40 passes the protrusion 73 of the long side plate 60.
