上記のように、折畳み状態にある複数の運搬用容器を積み重ねて運ぶ際と、組立て状態の複数の運搬用容器を積み重ねて運ぶ際のいずれにおいても、積み重なった複数の運搬用容器の全体が、傾いた姿勢になる場合がある。 As described above, in both the case of stacking and transporting a plurality of folded transport containers and the case of stacking and transporting a plurality of assembled transport containers, the entire stacked transport containers are as a whole. It may be in a tilted position.

これは、運搬用容器を積み重ねる作業のしやすさや、経年変化等を原因として将来的に運搬用容器が小さくなることを考慮して、上下の運搬用容器の間にクリアランスが生じるように設計されているからである。このクリアランスに起因して、上下の運搬用容器の間には水平方向の位置ずれが発生する。 This is designed so that there is a clearance between the upper and lower transport containers, considering the ease of stacking transport containers and the fact that the transport containers will become smaller in the future due to aging and other factors.

また、底板部２の下面２ｄには、格子状に交差する多数のリブから成る突段部２３が設けられている。突段部２３は、底板部２の下面２ｄのうち、周縁部２５の矩形枠状の下面２５ｄを除いた部分から、下方に向けて突出している。突段部２３と、これを囲む箇所に位置する四つの底板側係合部６２は、一体に形成されている。 Further, on the lower surface 2d of the bottom plate portion 2, a stepped portion 23 composed of a large number of ribs intersecting in a grid pattern is provided. The stepped portion 23 projects downward from the portion of the lower surface 2d of the bottom plate portion 2 excluding the rectangular frame-shaped lower surface 25d of the peripheral edge portion 25.

In the edge portion 251 whose longitudinal direction is the second direction D2, a lower engaging portion 72 is formed in the central portion of the second direction D2.

四枚の側板３について、さらに説明する。 The four side plates 3 will be further described.

四枚の側板３は、一対の折曲板４と、一対のあおり板５とから成る。 The four side plates 3 are composed of a pair of bent plates 4 and a pair of tilt plates 5.

一対の折曲板４はそれぞれ、水平軸まわりに回転自在なヒンジ部分４５を有する。ヒンジ部分４５は、折曲板４の上側半部と下側半部を、所定範囲内で回転自在に連結する部分である。 Each pair of folding plates 4 has a hinge portion 45 that is rotatable about a horizontal axis. The hinge portion 45 is a portion that rotatably connects the upper half portion and the lower half portion of the bent plate 4 within a predetermined range.

各折曲板４の上端縁部は、口枠部１が有する四つの辺部１１のうち対応する一つの辺部１１に対して、水平軸まわりに回転自在に連結されている。各折曲板４の下端縁部は、底板部２が有する四つの縁部２５１のうち対応する一つの縁部２５１に対して、水平軸まわりに回転自在に連結されている。各折曲板４は、口枠部１と底板部２の間において、内側に向けて略く字状に折れ曲がり可能に構成されている。 The upper end edge portion of each bent plate 4 is rotatably connected to one of the four side portions 11 of the mouth frame portion 1 around the horizontal axis. The lower end edge portion of each bent plate 4 is rotatably connected around a horizontal axis to one of the four edge portions 251 of the bottom plate portion 2 corresponding to the corresponding edge portion 251. Each bent plate 4 is configured to be able to be bent inward in a substantially shape between the mouth frame portion 1 and the bottom plate portion 2.

一対のあおり板５の各上端縁部は、口枠部１が有する四つの辺部１１のうち対応する一つの辺部１１に対して、水平軸まわりに回転自在に連結されている。各あおり板５の下端縁部は、底板部２が有する四つの縁部２５１のうち対応する一つの縁部２５１に対して、着脱自在に係止する。各あおり板５は、口枠部１と底板部２の間において、内側に向けて揺動自在に構成されている。 Each upper end edge portion of the pair of tilt plates 5 is rotatably connected to one of the four side portions 11 of the mouth frame portion 1 with respect to the corresponding side portion 11 around the horizontal axis. The lower end edge portion of each tilt plate 5 is detachably locked to one of the four edge portions 251 of the bottom plate portion 2 corresponding to the corresponding edge portion 251. Each tilt plate 5 is configured to swing inward between the mouth frame portion 1 and the bottom plate portion 2.

上記構成を備える運搬用容器９を折り畳むには、一対のあおり板５をそれぞれ内側に向けて回転させ、一対の折曲板４をそれぞれ内側に向けて略く字状に折り曲げる。これにより、運搬用容器９は、図３、図５に示すような折畳み状態となる。 In order to fold the transport container 9 having the above configuration, the pair of tilting plates 5 are rotated inward, and the pair of bent plates 4 are bent inward in a substantially shape. As a result, the transport container 9 is in a folded state as shown in FIGS. 3 and 5.

折畳み状態の運搬用容器９においては、口枠部１と、これの下方にある底板部２の周縁部２５が、上下に重なって位置する。 In the folded transport container 9, the mouth frame portion 1 and the peripheral edge portion 25 of the bottom plate portion 2 below the mouth frame portion 1 are vertically overlapped with each other.

より具体的には、口枠部１が有する四つの辺部１１と、底板部２の周縁部２５が有する四つの縁部２５１とが、一対一で上下に重なって位置する。 More specifically, the four side portions 11 of the mouth frame portion 1 and the four edge portions 251 of the peripheral edge portion 25 of the bottom plate portion 2 are positioned one-to-one so as to be vertically overlapped with each other.

上下に重なる辺部１１と縁部２５１において、辺部１１に形成された凹状の上側係合部７１と、縁部２５１に形成された凸状の下側係合部７２とが、僅かなクリアランスを介して係合することで、口枠部１と底板部２の間での水平方向の位置ずれ（以下「横ズレ」という。）が抑制される。 In the vertically overlapping side portion 11 and the edge portion 251 the concave upper engaging portion 71 formed on the side portion 11 and the convex lower engaging portion 72 formed on the edge portion 251 have a slight clearance. By engaging with each other, the horizontal displacement (hereinafter referred to as “lateral displacement”) between the mouth frame portion 1 and the bottom plate portion 2 is suppressed.

ここでのクリアランスは、辺部１１と縁部２５１の長手方向において設定されたクリアランスである。つまり、第一方向Ｄ１を長手方向とする辺部１１と縁部２５１においては、上側係合部７１と下側係合部７２の間に、第一方向Ｄ１のクリアランスが形成される。図４に示す上側係合部７１と下側係合部７２の場合、両者の間のクリアランスは、図示のクリアランスＣ１とクリアランスＣ２の和である。第二方向Ｄ２を長手方向とする辺部１１と縁部２５１においては、上側係合部７１と下側係合部７２の間に、第二方向Ｄ２のクリアランスが形成される。 The clearance here is a clearance set in the longitudinal direction of the side portion 11 and the edge portion 251. That is, in the side portion 11 and the edge portion 251 whose longitudinal direction is the first direction D1, a clearance in the first direction D1 is formed between the upper engaging portion 71 and the lower engaging portion 72. In the case of the upper engaging portion 71 and the lower engaging portion 72 shown in FIG. 4, the clearance between them is the sum of the shown clearances C1 and C2. In the side portion 11 and the edge portion 251 whose longitudinal direction is the second direction D2, a clearance in the second direction D2 is formed between the upper engaging portion 71 and the lower engaging portion 72.

図６、図７に示すように、組立て状態の運搬用容器９が上下に複数積み重なった（スタッキングされた）状態においては、下側の運搬用容器９の口枠部１に、上側の運搬用容器９の底板部２が載置される。以下において、上下の運搬用容器９を区別するときには、下側の運搬用容器９に符号９Ｌを付し、上側の運搬用容器９に符号９Ｕを付す。 As shown in FIGS. 6 and 7, when a plurality of assembled transport containers 9 are stacked (stacked) vertically, the upper transport container 9 is attached to the mouth frame portion 1 of the lower transport container 9 for upper transport. The bottom plate portion 2 of the container 9 is placed. In the following, when distinguishing between the upper and lower transport containers 9, the lower transport container 9 is designated by reference numeral 9L, and the upper transport container 9 is designated by reference numeral 9U.

上下に運搬用容器９Ｌ，９Ｕが積み重なった状態において、下側の運搬用容器９Ｌの口枠部１の開口には、上側の運搬用容器９Ｕの底板部２の突段部２３が嵌り込み、上下の運搬用容器９Ｌ，９Ｕの間の位置決めがなされる。突段部２３と口枠部１の間には、水平方向にクリアランスが設定されている。ここでのクリアランスは、成形後の熱収縮等を考慮して、第一方向Ｄ１において片側で２．５ｍｍ、全体で５ｍｍに設定され、同様に、第二方向Ｄ２において片側で２．５ｍ、全体で５ｍｍに設定されている。 In a state where the transport containers 9L and 9U are stacked vertically, the stepped portion 23 of the bottom plate portion 2 of the upper transport container 9U is fitted into the opening of the mouth frame portion 1 of the lower transport container 9L. Positioning is performed between the upper and lower transport containers 9L and 9U. A clearance is set in the horizontal direction between the step portion 23 and the mouth frame portion 1. The clearance here is set to 2.5 mm on one side in the first direction D1 and 5 mm in total in consideration of heat shrinkage after molding, and similarly, 2.5 m on one side in the second direction D2 and the whole. Is set to 5 mm.

また、上下に運搬用容器９Ｌ，９Ｕが積み重なった状態では、下側の運搬用容器９Ｌの口枠部１が有する四つの辺部１１と、上側の運搬用容器９Ｕの底板部２の周縁部２５が有する四つの縁部２５１とが、一対一で上下に重なって位置する。 Further, in a state where the transport containers 9L and 9U are stacked vertically, the four side portions 11 of the mouth frame portion 1 of the lower transport container 9L and the peripheral edge portion of the bottom plate portion 2 of the upper transport container 9U. The four edge portions 251 of the 25 are positioned one-to-one so as to be vertically overlapped with each other.

上下に重なる辺部１１と縁部２５１において、辺部１１に形成された凹状の口枠側係合部６１と、縁部２５１から突出するように形成された凸状の底板側係合部６２とが、僅かなクリアランスを介して係合する。これにより、下側の運搬用容器９Ｌと上側の運搬用容器９Ｕの間での横ズレが抑制される。 In the vertically overlapping side portions 11 and the edge portion 251 the concave mouth frame side engaging portion 61 formed on the side portion 11 and the convex bottom plate side engaging portion 62 formed so as to protrude from the edge portion 251. And engage through a small clearance. As a result, lateral displacement between the lower transport container 9L and the upper transport container 9U is suppressed.

ここでのクリアランスは、辺部１１と縁部２５１の長手方向において設定されたクリアランスである。つまり、第一方向Ｄ１を長手方向とする辺部１１と縁部２５１においては、口枠側係合部６１と底板側係合部６２の間に、第一方向Ｄ１のクリアランスが形成される。図７に示す口枠側係合部６１と底板側係合部６２の場合、両者の間のクリアランスは、図示のクリアランスＣ３とクリアランスＣ４の和である。第二方向Ｄ２を長手方向とする辺部１１と縁部２５１においては、口枠側係合部６１と底板側係合部６２の間に、第二方向Ｄ２のクリアランスが形成される。 The clearance here is a clearance set in the longitudinal direction of the side portion 11 and the edge portion 251. That is, in the side portion 11 and the edge portion 251 whose longitudinal direction is the first direction D1, a clearance in the first direction D1 is formed between the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62. In the case of the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 shown in FIG. 7, the clearance between the two is the sum of the shown clearances C3 and C4. In the side portion 11 and the edge portion 251 whose longitudinal direction is the second direction D2, a clearance in the second direction D2 is formed between the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62.

ここで、口枠側係合部６１とこれに係合する底板側係合部６２との間のクリアランスは、口枠部１とこれに嵌る突段部２３との間のクリアランス（＝５ｍｍ）よりも、小さな寸法（たとえば３ｍｍ）で設定されている。図７に示す口枠側係合部６１と底板側係合部６２の場合、図示のクリアランスＣ３とクリアランスＣ４がそれぞれ１．５ｍｍであるから、口枠側係合部６１と底板側係合部６２の間のクリアランスは、クリアランスＣ３，Ｃ４の和で３ｍｍである。 Here, the clearance between the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 engaged with the mouth frame side engaging portion 61 is the clearance (= 5 mm) between the mouth frame portion 1 and the stepped portion 23 fitted therein. It is set with a smaller dimension (for example, 3 mm) than that. In the case of the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 shown in FIG. 7, since the shown clearance C3 and the clearance C4 are 1.5 mm each, the mouth frame side engaging portion 61 and the bottom plate side engaging portion are The clearance between 62 is 3 mm, which is the sum of the clearances C3 and C4.

なお、口枠側係合部６１と底板側係合部６２との間のクリアランスは、上記のような片側（Ｃ３＝Ｃ４＝）１．５ｍｍ、合計（Ｃ３＋Ｃ４＝）３ｍｍに限定されず、片側０．５ｍｍ～１．５ｍｍ、合計１ｍｍ～３ｍｍ（好ましくは片側０．５ｍｍ～１ｍｍ、合計１ｍｍ～２ｍｍ）の範囲内で設定することが可能である。 The clearance between the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 is not limited to 1.5 mm on one side (C3 = C4 =) and 3 mm in total (C3 + C4 =) as described above, and is not limited to one side. It can be set within the range of 0.5 mm to 1.5 mm, total 1 mm to 3 mm (preferably 0.5 mm to 1 mm on one side, total 1 mm to 2 mm).

上記した各構成を備える運搬用容器９によれば、組立て状態の運搬用容器９を上下に複数（多数）積み重ねて運ぶ際に、全体が傾くことが抑えられる。 According to the transport container 9 having each of the above configurations, when a plurality (many) of the transport containers 9 in the assembled state are stacked vertically and transported, the whole can be suppressed from tilting.

つまり、組立て状態の運搬用容器９を上下に積み重ねた状態において、下側の運搬用容器９Ｌの口枠部１に形成された四つの口枠側係合部６１と、上側の運搬用容器９Ｕに形成された四つの底板側係合部６２とが一対一に係合することで、上下の運搬用容器９Ｌ，９Ｕの間の横ズレが、第一方向Ｄ１と第二方向Ｄ２の両方において効果的に抑制される。 That is, in a state where the assembled transport containers 9 are stacked vertically, the four mouth frame side engaging portions 61 formed in the mouth frame portion 1 of the lower transport container 9L and the upper transport container 9U. By engaging one-to-one with the four bottom plate side engaging portions 62 formed in, the lateral displacement between the upper and lower transport containers 9L and 9U is caused in both the first direction D1 and the second direction D2. Effectively suppressed.

ここで、各口枠側係合部６１は、口枠部１の辺部１１の中央部分に位置し、各底板側係合部６２は、底板部２の縁部２５１の中央部分に位置するので、口枠部１と底板部２の少なくとも一方に成形後の熱収縮や経年変化が生じても、これが横ズレ抑制の機能に影響を及ぼすことは抑えられる。 Here, each mouth frame side engaging portion 61 is located at the central portion of the side portion 11 of the mouth frame portion 1, and each bottom plate side engaging portion 62 is located at the central portion of the edge portion 251 of the bottom plate portion 2. Therefore, even if heat shrinkage or secular variation occurs after molding in at least one of the mouth frame portion 1 and the bottom plate portion 2, it is possible to suppress that this affects the function of suppressing lateral displacement.

また、上記した各構成を備える運搬用容器９によれば、図８に示すように、折畳み状態の運搬用容器９を上下に複数（多数）積み重ねて運ぶ際に、全体が大きく傾くことが効果的に抑えられる。 Further, according to the transport container 9 having each of the above configurations, as shown in FIG. 8, when a plurality (many) of the transport containers 9 in the folded state are stacked vertically and transported, it is effective that the whole is greatly tilted. Can be suppressed.

つまり、折畳み状態の運搬用容器９を上下に積み重ねた状態においても、四つの口枠側係合部６１と、四つの底板側係合部６２とが一対一に係合することで、第一方向Ｄ１と第二方向Ｄ２の両方において横ズレが抑制される。 That is, even when the folded transport containers 9 are stacked vertically, the four mouth frame side engaging portions 61 and the four bottom plate side engaging portions 62 are engaged one-to-one, so that the first Lateral deviation is suppressed in both the direction D1 and the second direction D2.

加えて、折畳み状態の運搬用容器９において、口枠部１が有する四つの上側係合部７１と、底板部２が有する四つの下側係合部７２とが一対一に係合することで、各運搬用容器９における口枠部１と底板部２の間の横ズレが抑制される。そのため、折畳み状態の運搬用容器９を上下に複数（多数）積み重ねて運ぶ際の全体の傾きが、一層効果的に抑制される。 In addition, in the folded transport container 9, the four upper engaging portions 71 of the mouth frame portion 1 and the four lower engaging portions 72 of the bottom plate portion 2 engage one-to-one. , The lateral displacement between the mouth frame portion 1 and the bottom plate portion 2 in each transport container 9 is suppressed. Therefore, the overall inclination when a plurality (many) of the folded transport containers 9 are stacked vertically is suppressed more effectively.

既述の如く、折畳み状態の運搬用容器９を積み重ねて運ぶ際には、特に多数（たとえば２０個程度）の運搬用容器９を積み重ねる場合が多く、その分だけ全体が大きく傾きやすくなるが、実施形態１の運搬用容器９においては、口枠側係合部６１と底板側係合部６２の係合と、上側係合部７１と下側係合部７２の係合の両方によって、全体の傾きがより効果的に抑えられる。 As described above, when stacking and transporting the folded transport containers 9, it is often the case that a large number (for example, about 20) of the transport containers 9 are stacked, and the whole is easily tilted by that amount. In the transport container 9 of the first embodiment, the whole is formed by both the engagement of the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 and the engagement of the upper engaging portion 71 and the lower engaging portion 72. Tilt is suppressed more effectively.

ここで、各上側係合部７１は、口枠部１の辺部１１の中央部分に位置し、各下側係合部７２は、底板部２の縁部２５１の中央部分に位置するので、口枠部１や底板部２に成形後の熱収縮や経年変化が生じても、これが横ズレ抑制の機能に影響を及ぼすことは抑えられる。 Here, since each upper engaging portion 71 is located at the central portion of the side portion 11 of the mouth frame portion 1, and each lower engaging portion 72 is located at the central portion of the edge portion 251 of the bottom plate portion 2. Even if heat shrinkage or secular variation occurs in the mouth frame portion 1 or the bottom plate portion 2 after molding, it is possible to suppress this from affecting the function of suppressing lateral displacement.

さらに、実施形態１の運搬用容器９においては、各口枠側係合部６１が、口枠部１の内方に向けて開口するように凹状に形成されているので、各口枠側係合部６１に水や埃がたまり難くなっている。実施形態１では、各口枠側係合部６１の底面を略水平に設けているが、該底面を、口枠部１の内方に近づくほど下方に位置するように傾斜させて設けた場合には、洗浄後の水切りがさらに良好となる。 Further, in the transport container 9 of the first embodiment, each mouth frame side engaging portion 61 is formed in a concave shape so as to open inward toward the mouth frame portion 1, so that each mouth frame side engaging portion is engaged. Water and dust are less likely to collect in the joint 61. In the first embodiment, the bottom surface of each mouth frame side engaging portion 61 is provided substantially horizontally, but when the bottom surface is tilted so as to be positioned downward as it approaches the inside of the mouth frame portion 1. The drainage after washing becomes even better.

（実施形態２）
図９乃至図１２には、実施形態２の運搬用容器９を示している。以下において、実施形態１と同様の構成については、同一符号を付して詳しい説明を省略する。 (Embodiment 2)
9 to 12 show the transport container 9 of the second embodiment. Hereinafter, the same configurations as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

図９等に示すように、実施形態２の運搬用容器９において、四箇所の口枠側係合部６１の各々は、口枠部１の外周面１ｂの一部が凹んだ形状を有する。より具体的には、口枠部１が備える四つの辺部１１の外周面１１ｂに一つずつ位置するように、四つの口枠側係合部６１が形成されている。 As shown in FIG. 9 and the like, in the transport container 9 of the second embodiment, each of the four mouth frame side engaging portions 61 has a shape in which a part of the outer peripheral surface 1b of the mouth frame portion 1 is recessed. More specifically, the four mouth frame side engaging portions 61 are formed so as to be located one by one on the outer peripheral surface 11b of the four side portions 11 included in the mouth frame portion 1.

各口枠側係合部６１は、口枠部１の外方に向けて開口し、且つ、上方に向けて開口するように、口枠部１の上縁の外側の角部分に形成されている。第一方向Ｄ１を長手方向とする辺部１１においては、その第一方向Ｄ１の中央部分に口枠側係合部６１が形成されている。第二方向Ｄ２を長手方向とする辺部１１においては、その第二方向Ｄ２の中央部分に口枠側係合部６１が形成されている。 Each mouth frame side engaging portion 61 is formed in the outer corner portion of the upper edge of the mouth frame portion 1 so as to open outward and upward of the mouth frame portion 1. There is. In the side portion 11 having the first direction D1 as the longitudinal direction, the mouth frame side engaging portion 61 is formed in the central portion of the first direction D1. In the side portion 11 having the second direction D2 as the longitudinal direction, the mouth frame side engaging portion 61 is formed in the central portion of the second direction D2.

図１０に示すように、実施形態２の運搬用容器９において、底板部２から突出する四箇所の底板側係合部６２の各々は、突段部２３との間に距離をあけて位置している。 As shown in FIG. 10, in the transport container 9 of the second embodiment, each of the four bottom plate side engaging portions 62 protruding from the bottom plate portion 2 is located at a distance from the stepped portion 23. ing.

図１１、図１２に示すように、実施形態２の運搬用容器９においても、上下に運搬用容器９Ｌ，９Ｕが積み重なった状態において、下側の運搬用容器９Ｌの口枠部１の開口に、上側の運搬用容器９Ｕの底板部２の突段部２３が嵌り込むとともに、下側の運搬用容器９Ｌの口枠部１に形成された四つの口枠側係合部６１と、上側の運搬用容器９Ｕに形成された四つの底板側係合部６２とが、一対一に係合する。 As shown in FIGS. 11 and 12, also in the transport container 9 of the second embodiment, when the transport containers 9L and 9U are stacked vertically, the opening of the mouth frame portion 1 of the lower transport container 9L is opened. , The stepped portion 23 of the bottom plate portion 2 of the upper transport container 9U is fitted, and the four mouth frame side engaging portions 61 formed in the mouth frame portion 1 of the lower transport container 9L and the upper side. The four bottom plate side engaging portions 62 formed in the transport container 9U engage one-to-one.

凹状の口枠側係合部６１と凸状の底板側係合部６２の間には、僅かなクリアランスが形成される。図１２に示す口枠側係合部６１と底板側係合部６２の場合、両者の間のクリアランス（辺部１１と縁部２５１の長手方向である第一方向Ｄ１のクリアランス）は、図示のクリアランスＣ５とクリアランスＣ６の和である。 A slight clearance is formed between the concave mouth frame side engaging portion 61 and the convex bottom plate side engaging portion 62. In the case of the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 shown in FIG. 12, the clearance between the two (the clearance in the first direction D1 which is the longitudinal direction of the side portion 11 and the edge portion 251) is shown in the figure. It is the sum of the clearance C5 and the clearance C6.

実施形態２の運搬用容器９においても、口枠側係合部６１とこれに係合する底板側係合部６２との間のクリアランスは、口枠部１とこれに嵌る突段部２３との間のクリアランス（たとえば５ｍｍ）よりも、小さな寸法（たとえば３ｍｍ）で設定されている。 Also in the transport container 9 of the second embodiment, the clearance between the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 engaged with the mouth frame side engaging portion is set between the mouth frame portion 1 and the stepped portion 23 fitted therein. It is set to a smaller dimension (eg 3 mm) than the clearance between (eg 5 mm).

口枠側係合部６１と底板側係合部６２との間のクリアランスは、上記のような片側（Ｃ５＝Ｃ６＝）１．５ｍｍ、合計（Ｃ５＋Ｃ６＝）３ｍｍに限定されず、片側０．５ｍｍ～１．５ｍｍ、合計１ｍｍ～３ｍｍ（好ましくは片側０．５ｍｍ～１ｍｍ、合計１ｍｍ～２ｍｍ）の範囲内で設定することが可能である。 The clearance between the mouth frame side engaging portion 61 and the bottom plate side engaging portion 62 is not limited to 1.5 mm on one side (C5 = C6 =) as described above, and the total (C5 + C6 =) is 3 mm. It can be set within the range of 5 mm to 1.5 mm, total 1 mm to 3 mm (preferably 0.5 mm to 1 mm on one side, total 1 mm to 2 mm).

したがって、実施形態２の運搬用容器９によれば、組立て状態の運搬用容器９を上下に複数（多数）積み重ねて運ぶ際に、全体が傾くことが抑えられる。折畳み状態の運搬用容器９を上下に複数（多数）積み重ねて運ぶ際には、各運搬用容器９において上側係合部７１と下側係合部７２が係合することによっても、全体の傾きが抑えられる。 Therefore, according to the transport container 9 of the second embodiment, when a plurality (many) of the transport containers 9 in the assembled state are stacked vertically and transported, the whole can be suppressed from tilting. When a plurality (many) of the folded transport containers 9 are stacked vertically and transported, the upper engaging portion 71 and the lower engaging portion 72 are engaged with each transport container 9, and the entire tilt is also formed. Is suppressed.

さらに、実施形態２の運搬用容器９においては、各口枠側係合部６１が、口枠部１の外方に向けて開口するように凹状に形成されているので、各口枠側係合部６１に水や埃がたまり難くなっている。実施形態２の運搬用容器９では、各口枠側係合部６１の底面を略水平に設けているが、該底面を、口枠部１の外方に近づくほど下方に位置するように傾斜させて設けた場合には、洗浄後の水切りがさらに良好となる。また、実施形態２の運搬用容器９では、各口枠側係合部６１が口枠部１の内方に向けて開口していないので、各口枠側係合部６１に収納物が引っ掛かりにくいという利点がある。 Further, in the transport container 9 of the second embodiment, each mouth frame side engaging portion 61 is formed in a concave shape so as to open toward the outside of the mouth frame portion 1, so that each mouth frame side engaging portion is engaged. Water and dust are less likely to collect in the joint 61. In the transport container 9 of the second embodiment, the bottom surface of each mouth frame side engaging portion 61 is provided substantially horizontally, but the bottom surface is inclined so as to be positioned downward as it approaches the outside of the mouth frame portion 1. If it is provided so as to be provided, the drainage after washing becomes even better. Further, in the transport container 9 of the second embodiment, since each mouth frame side engaging portion 61 does not open toward the inside of the mouth frame portion 1, the stored object is caught by each mouth frame side engaging portion 61. It has the advantage of being difficult.

したがって、実施形態１－５の運搬用容器９によれば、この運搬用容器９を折畳み状態で上下に複数（多数）積み重ねて運ぶ際に全体が大きく傾くことが、それぞれの運搬用容器９で上側係合部７１と下側係合部７２が係合することによって、効果的に抑えられる。そのため、複数積み重ねた運搬用容器９を移動させる際にも、荷崩れを生じることが抑えられる。 Therefore, according to the transport container 9 of the first to fifth embodiment, when a plurality (many) of the transport containers 9 are stacked up and down in a folded state and transported, the whole is greatly tilted in each transport container 9. By engaging the upper engaging portion 71 and the lower engaging portion 72, it is effectively suppressed. Therefore, even when a plurality of stacked transport containers 9 are moved, it is possible to prevent the load from collapsing.
