Description

【0001】
【発明の属する技術分野】
本発明は、折り畳みコンテナにおいて内部に水が浸入するのを防止するための技術に関するものである。
【0002】
【従来の技術】
外周に上方に向けて立ち上がり片を突設した平面視長方形状をした底板と、平面視長方形状をした上枠と、上端部が上枠に回動自在に枢支され且つ下端部が底板に回動自在に枢支された一対の長辺側の側板と、上端部又は下端部の一端部が上枠又は底板のいずれか一方に回動自在に枢支された一対の短辺側の側板とで構成され、折り畳み状態において底板上に内側に折り畳んだ長辺側の側板と短辺側の側板とが重ねられ、両長辺側の側板を起立させると共に両短辺側の側板を起立させた状態で、長辺側の側板の下端部外面及び短辺側の側板の下端部外面が底板の立ち上がり片の内側に沿って起立するようにした折り畳みコンテナが知られている。この折り畳みコンテナは、上下両端部を上枠と底板とに回動自在に枢支した長辺側の折り畳み自在な側板は組み立てる際に、内側から起立させながら、長辺側の底板の下端部の外面を底板の長辺側の立ち上がり片の内側に沿って起立させることで、起立状態において外側に倒れないようにしており、また、短辺側の側板も起立させた際に短辺側の側板の下端部外面を短辺側の立ち上がり片に沿って起立させることで、起立状態において外側に倒れないようにしている。
【0003】
更に、上記底板の外周部において上方に突設した立ち上がり片は、折り畳んだ状態で底板上に折り畳んで重ねる側板を収納する役目をしている。
これらの理由により従来からこの種の折り畳みコンテナにおいては、底板の外周に立ち上がり片を突設するようになっている。
ところが、折り畳みコンテナを組み立てた状態で、側板に生じた結露水や、側板に付着した雨水が立ち上がり片と側板の下端部外面との間から浸入して折り畳みコンテナ内に浸入し、折り畳みコンテナ内に収納している収納物に悪影響を及ぼすという問題がある。また、折り畳みコンテナ内に収納している収納物を冷凍庫から出した場合など立ち上がり片が堤として機能してしまって、解凍液が折り畳みコンテナ内に溜まってしまい、内容物に悪影響を及ぼすという問題がある。
【0004】
更に、折り畳みコンテナに蓋体を取付ける場合、一枚の大きな蓋を取付けると、蓋体の開閉に広いスペースが必要であり、また、側板の大きさが上枠よりも小さいと、蓋体の一端部を上枠に枢支した場合、蓋体を開いた際に側板に沿わせて垂直に垂らすことができず、蓋体が斜めになってしまって蓋体が邪魔になるという問題がある。そこで、平面視長方形状をした上枠の対向する2辺にそれぞれ扉体を回動自在に取付け、両蓋体を閉じることで、上枠の開口部を閉じるようにし、開いた場合には両側の蓋体をそれぞれ両側の側板に沿わせて垂直に垂らすことができるようにすることが考えられている。
【0005】
ところが、このように2枚の蓋体を閉じた場合、両蓋体の先端部間から内部に水が浸入するという問題がある。
更に、両蓋体を閉じた際に、積み重ねたりすることで上方から荷重がかかると、両蓋体の先端部間が広がってしまうという問題がある。
【0006】
【発明が解決しようとする課題】
本発明は上記の従来例の問題点に鑑みて発明したものであって、立ち上がり片と側板の下端部外面との間の隙間から水が浸入しても、この水が折り畳みコンテナ内に浸入するのが防止でき、また、2枚の蓋体の先端の重複部分から内部に水が浸入するのを確実に防止でき、更に、両蓋体を閉じた際に両蓋体の先端部間が広がらないようにできる折り畳みコンテナを提供することを課題とするものである。
【0007】
【課題を解決するための手段】
上記本発明の課題を解決するために本発明の折り畳みコンテナは、外周に上方に向けて立ち上がり片1を突設した平面視長方形状をした底板2と、平面視長方形状をした上枠3と、上端部が上枠3に回動自在に軸支され且つ下端部が底板2に回動自在に枢支された一対の長辺側の側板4と、上端部又は下端部の一端部が上枠3又は底板2のいずれか一方に回動自在に枢支された一対の短辺側の側板5とで構成され、折り畳み状態において底板2上に内側に折り畳んだ長辺側の側板4と短辺側の側板5とが重ねられ、両長辺側の側板4を起立させると共に両短辺側の側板5を起立させた状態で、長辺側の側板4の下端部外面及び短辺側の側板5の下端部外面が底板2の立ち上がり片1の内側に沿って起立するようにした折り畳みコンテナ6であって、底板2の上面部の外周に立ち上がり片1の内側に沿って排水溝7を形成し、該排水溝7に連通した外部に排水するための排水部7aを設け、平面視長方形状をした上枠3の対向する2辺にそれぞれ扉体8を回動自在に取付け、一対の扉体8の先端部を重複させ、該一対の扉体8の先端部の重複部分において下重複部9の上面部に端部に外部への排出部10を有する排水凹溝部11部を形成して成ることを特徴とするものである。このような構成とすることで、立ち上がり片1と長辺側の側板4との間又は立ち上がり片1と短辺側の側板5との間から水が浸入しても、底板2の上面部の立ち上がり片1の内側に沿って形成した排水溝7に沿って流して排水部7aから外部に排水できて、折り畳みコンテナ6の内部に浸入しないようになっている。また、一対の蓋体8を閉じて一方の蓋体8の下重複部9の上に他方の蓋体8の上重複部12を重ねるのであるが、該下重複部9と上重複部12との重複部分に水が浸入しても、下重複部9の上面部に形成した排水凹溝部11に沿って水を流して端部の排出部10から外部に排水できて、折り畳みコンテナ6の内部に浸入しないようになっている。
【0009】
また、上重複部12に嵌め込み用垂下片13を突設し、該嵌め込み用垂下片13を排水凹溝部11の下重複部9の先端側に近い側面側に偏らせて嵌め込むことも好ましい。このような構成とすることで、一対の扉体8間が広がろうとするのを嵌め込み用垂下片13の排水凹溝部11への嵌め込みにより防止することができるものであり、しかも、嵌め込み用垂下片13を排水凹溝部11内に嵌め込むといえども嵌め込み用垂下片13を排水凹溝部11の下重複部9の先端側に近い側面側に偏らせて嵌め込むことで、下重複部9と上重複部12との重複部分に浸入した水が排水凹溝部11内を流れるのに支障がないものであり、また、排水凹溝部11に嵌め込まれた嵌め込み用垂下片13によっても水のそれ以上の浸入が防止されることになる。
【0010】
【発明の実施の形態】
以下本発明を添付図面に示す実施形態に基づいて説明する。本発明の折り畳みコンテナ6は、図3乃至図8に示すように、平面視長方形状をした底板2と、平面視長方形状をした上枠3と、上側板部15と下側板部16とを中間枢支部17で折り畳み自在に枢支した一対の長辺側の側板4と、一対の短辺側の側板5とを組み立てて構成してある。
【0011】
ここで、図9に示すように、底板2の外周部には上方に向けて立ち上がり片1が全長にわたって突出形成してある。また、底板2の上面部の立ち上がり片1の内側に沿って排水溝7が全長に形成してある。この排水溝7には任意の位置に排水孔が形成してあって、該排水孔が排水溝7から水を外部に排出するための排水部7aとなっている。
【0012】
図4に示すように、長辺側の側板4の上側板部15の上端部の両側が軸18により上枠3に回動自在に取付けてあり、また、長辺側の側板4の下側板部16の下端部の両側が軸19により底板2に回動自在に取付けてある。そして、この長辺側の側板4は中間枢支部17を中心にして内側に向けてく字状に折り畳むことができるようになっており、上側板部15と下側板部16とが重なるように折り畳んだ状態で底板2の上面に重ねられるようになっている。したがって、底板2の上面の両側に両側の長辺側の側板4をそれぞれ折り畳んで重ねることができるように、長辺側の側板4を折り畳んだ状態では底板2の短辺側の辺の長さの略1/2以下の長さに設定してある。
【0013】
短辺側の側板5は上端部が上枠3に回動自在に枢支してあり、折り畳む時には短辺側の側板5を回動して略水平姿勢にした状態で上記底板2の上に折り畳んで重ねている長辺側の側板4の上に重ねるようになっている。
上記のように長辺側の側板4、短辺側の側板5を折り畳んだ状態では図7、図8に示すように、底板2の外周の立ち上がり片1及び上枠3内に上記側板4、5が収納されて外部から見えないようになっている。
【0014】
そして、一対の長辺側の側板4を展延して起立させると共に一対の短辺側の側板5を回動して起立させることで図3、図4のように折り畳みコンテナ6を容器状に組み立てるものである。この場合、図1に示すように、長辺側の側板4の上端部外面及び下端部外面はそれぞれ上枠3の内面、立ち上がり辺1の内面に近接対向し、長辺側の側板4が外側に倒れないようになっている。ここで、更に、上側板部15と下側板部16とを枢支する中間枢支部17が図1のように上側板部15の上端の外面側と下側板部16の下端の外面側とを枢支しているので、この中間枢支部17の構造によっても、長辺側の側板4が外側に折れるのを防止しており、更に、図2に示すように、上側板部15の上端と下側板部16の下端の外面側にそれぞれ折れ曲がり防止突片20を設けて、起立姿勢において、上側板部15の下端の折れ曲がり防止突片20が下側板部16の上端部内面に当接し、下側板部16の上端の折れ曲がり防止突片20が上側板部15の下端部内面に当接することによっても、長辺側の側板4が外側に折れるのを防止している。
【0015】
一方、短辺側の側板5を回動して起立させると、図2に示すように、短辺側の側板5の下端部外面が立ち上がり片1の内面に近接対向し、短辺側の側板5の下端部が外側に飛び出すのが防止してある。そして、短辺側の側板5を起立させることで、短辺側の側板5の両端部がそれぞれ両側の起立した長辺側の側板4の内面に当接し、これにより短辺側の側板5を回動して略水平姿勢にしないかぎり長辺側の側板4が内側に折り曲げられないようになっている。つまり、折り畳みコンテナ6を容器状に組み立てた状態が保持されるのである。
【0016】
平面視長方形状をした上枠3の対向する長辺側の縁部には図23に示すようにヒンジ部材21によりそれぞれ蓋体8を回動自在に取付けてある。蓋体8は図12乃至図22に示すようなもので、対向する長辺の一方側にヒンジ部材21の取付け部22を有しており、他の長辺側の長辺に沿った片側半分が下重複部9となっており、他の片側半部が前方に向けて突出した突片となっていて該突片が上重複部12となっている。下重複部9と上重複部12との境界部分は斜めに傾斜した傾斜縁部23となっている。
【0017】
下重複部9の上面部は蓋体8の上面部よりも一段下方に下がっており、図14に示すようにこの下重複部9の上面部には下重複部9の全長にわたって排水凹溝部11が形成してあり、該排水凹溝部11の一端部は下重複部9上において上記傾斜縁部23に沿って下重複部9の先端まで到るように形成してある。該傾斜縁部23に沿った排水凹溝部11の先端は堰35により止水してある。排水凹溝部11の他端部は外側方に開口して排出部10となっている。
【0018】
上重複部12は下重複部9にぴったりと重複することができる形状となっており、この上重複部12の下面部は蓋体8の下面部よりも一段上方に上がっている。そして、この下重複部9の下面部に嵌め込み用垂下片13が下重複部9の長手方向にわたって垂設してある。
上枠3の上端部の内周部には上方に向けて上突出片24が突設してあり、一対の蓋体8を回動して上枠3の開口を閉じた状態で蓋体8の外端部に設けた垂下縁片25が上記上突出片24の外側に位置して上突出片24を覆うようになっている。この場合、蓋体8に下方に向けて凹設することで排水凹溝部11が形成されるので、この排水凹溝部11の下面側が嵌まり込むための切欠部27を上記上突出片24に形成してある。したがって、排水凹溝部11を下方に凹設しても蓋体8を閉じるのに支障がなくなったものであり、しかも該排水凹溝部11の端部の排出部10は上突出片24よりも外側において外部に開口することになり、排出部10から排出する水が折り畳みコンテナ6内に浸入することがないようにしている。
【0019】
一対の蓋体8は互いに180°回転対称となるように配置されるものであり、蓋体8を閉じるには、両蓋体8をヒンジ部材21部分を中心にして回動し、一方の蓋体8の下重複部9に他方の蓋体8の上重複部12を重ねると共に他方の蓋体の下重複部9に一方の蓋体8の上重複部12を重ねるものである。この場合、各上重複部12に突設した嵌め込み用垂下片13が排水凹溝部11の下重複部9の先端側に近い側面側に偏らせて嵌め込まれるものである。
【0020】
上記のような構成の本発明においては、折り畳みコンテナ6を組立てた状態で、結露水や雨水等の水が立ち上がり片1と長辺側の側板4との間又は立ち上がり片1と短辺側の側板5との間から浸入しても、この立ち上がり片1と側板との間から浸入した水は底板2の上面部の立ち上がり片1の内側に沿って形成した排水溝7に沿って流れて排水部7aから外部に排水され、折り畳みコンテナ6の内部に浸入しないようなっている。また、折り畳みコンテナ6内に収納している収納物を冷凍庫から出した場合なども、排水凹溝部11に沿って流して排水部7aから外部に排水することができるものである。
【0021】
一方、上枠3は一対の蓋体8を閉じることで、折り畳みコンテナ6の上開口を閉じるのであるが、一対の蓋体8の先端部の重複部分から水が入っても、下重複部9に設けた排水凹溝部11に流れ込み、排水凹溝部11内を流れて端部の排出部10から外部に排出されることになり、したがって、蓋体8の先端部の重複部分に水が入っても、これが折り畳みコンテナ6内に浸入しないようになっている。
【0022】
ここで、図13に示すように、嵌め込み用垂下片13が排水凹溝部11に嵌め込んであるので、一対の扉体8間が広がろうとするのを嵌め込み用垂下片13の排水凹溝部11への嵌め込みにより防止するようになっており、しかも、嵌め込み用垂下片13を排水凹溝部11内に嵌め込むといえども嵌め込み用垂下片13を排水凹溝部11の下重複部の先端側に近い側面側に偏らせて嵌め込むことで、下重複部9と上重複部12との重複部分に浸入した水が排水凹溝部11内を流れるのに支障がないものである。また、排水凹溝部11に嵌め込まれた嵌め込み用垂下片13によっても水のそれ以上の浸入が防止されるようになっている。
【0023】
なお、折り畳みコンテナ6を容器状に組み立てた状態で上下多段に積み重ねることができるようにしてある。このように上下に多段に積む場合には、最上段の折り畳みコンテナ6に蓋体8があればよく、他の折り畳みコンテナ6には蓋体8がない場合であってもよい。もちろん、下段の折り畳みコンテナ6にも蓋体8を設けてもよいものである。いずれにせよ折り畳みコンテナ6を容器状に組み立てたものを上下に多段に積み重ねた場合、底板2の外端部に設けた排水部7aは上突出片24よりも外側に位置するようになっており、立ち上がり片1と側板の外面下端部との間の隙間から浸入した水が排水溝7に流れて排水部7aから排水される際に、上突出片24よりも外側において外部に排出され、下段の折り畳みコンテナ6内に浸入することがないものである。
【0024】
【発明の効果】
本発明の請求項1記載の発明にあっては、上述のように、底板の上面部の外周に立ち上がり片の内側に沿って排水溝を形成し、該排水溝に連通した外部に排水するための排水部を設けてあるので、立ち上がり片と長辺側の側板との間又は立ち上がり片と短辺側の側板との間から水が浸入しても、底板の上面部の立ち上がり片の内側に沿って形成した排水溝に沿って流して排水部から外部に排水できて、折り畳みコンテナの内部に浸入せず、折り畳みコンテナ内に収納している収納物が水でおかされず、また、折り畳みコンテナ内に収納している収納物を冷凍庫から出した場合なども、排水凹溝部に沿って流して排水部から外部に排水することができるものである。また、平面視長方形状をした上枠の対向する2辺にそれぞれ扉体を回動自在に取付け、一対の扉体の先端部を重複させ、該一対の扉体の先端部の重複部分において下重複部の上面部に端部に外部への排出部を有する排水凹溝部を形成してあるので、一対の蓋体を閉じて一方の蓋体の下重複部の上に他方の蓋体の上重複部を重ねるのであるが、該下重複部と上重複部との重複部分に水が浸入しても、下重複部の上面部に形成した排水凹溝部に沿って水を流して端部の排出部から外部に排水できて、折り畳みコンテナの内部に浸入せず、折り畳みコンテナ内に収納している収納物が水でおかされないものである。
【0026】
また、請求項2記載の発明にあっては、上記請求項1記載の発明の効果に加えて、上重複部に嵌め込み用垂下片を突設し、該嵌め込み用垂下片を排水溝の下重複部の先端側に近い側面側に偏らせて嵌め込んであるので、一対の扉体間が広がろうとするのを嵌め込み用垂下片の排水凹溝部への嵌め込みにより防止することができるものであり、しかも、嵌め込み用垂下片を排水溝内に嵌め込むといえども嵌め込み用垂下片を排水凹溝部の下重複部の先端側に近い側面側に偏らせて嵌め込むことで、下重複部と上重複部との重複部分に浸入した水が排水凹溝部内を流れるのに支障がないものであり、また、排水凹溝部に嵌め込まれた嵌め込み用垂下片によっても水のそれ以上の浸入が防止できるものであり、この結果、折り畳みコンテナ内に収納している収納物が水でおかされないものである。

BACKGROUND OF THE INVENTION
The present invention relates to a technique for preventing water from entering inside a folding container.
[0002]
[Prior art]
A bottom plate having a rectangular shape in plan view with a rising piece protruding upward on the outer periphery, a top frame having a rectangular shape in plan view, an upper end portion pivotally supported by the upper frame, and a lower end portion on the bottom plate A pair of side plates on the long side that are pivotally supported, and a pair of side plates on the short side that one end of the upper end or the lower end is pivotally supported on either the upper frame or the bottom plate. The side plate on the long side and the side plate on the short side, which are folded inward on the bottom plate in the folded state, are overlapped, and the side plates on both long sides are raised while the side plates on both short sides are raised. In this state, a folding container is known in which the outer surface of the lower end of the side plate on the long side and the outer surface of the lower end of the side plate on the short side rise up along the inside of the rising piece of the bottom plate. This foldable container has a long side foldable side plate pivotally supported by an upper frame and a bottom plate at both upper and lower ends. The outer surface is erected along the inside of the rising piece on the long side of the bottom plate, so that it does not fall outside in the standing state, and the side plate on the short side when the side plate on the short side is also erected By raising the outer surface of the lower end portion along the rising piece on the short side, it is prevented from falling outside in the standing state.
[0003]
Further, the rising piece projecting upward on the outer peripheral portion of the bottom plate serves to store a side plate that is folded and stacked on the bottom plate in a folded state.
For these reasons, conventionally, in this type of folding container, rising pieces protrude from the outer periphery of the bottom plate.
However, when the folding container is assembled, condensed water generated on the side plate and rainwater adhering to the side plate enter from between the rising piece and the outer surface of the lower end of the side plate and enter the folding container, and enter the folding container. There is a problem of adversely affecting the stored items. In addition, when the stored items stored in the folding container are taken out of the freezer, the rising piece functions as a bank, and the thawing solution accumulates in the folding container, which adversely affects the contents. is there.
[0004]
Furthermore, when a lid is attached to a folding container, if a large lid is attached, a large space is required to open and close the lid, and if the size of the side plate is smaller than the upper frame, one end of the lid When the part is pivotally supported by the upper frame, there is a problem that when the lid is opened, the lid cannot be hung vertically along the side plate, and the lid is inclined to obstruct the lid. Therefore, the door body is pivotally attached to two opposite sides of the upper frame that is rectangular in plan view, and both lids are closed to close the opening of the upper frame. It is considered that the lids can be suspended vertically along the side plates on both sides.
[0005]
However, when the two lids are closed in this way, there is a problem that water enters the inside from between the front end portions of both lids.
Furthermore, when both lids are closed, if a load is applied from above by stacking them, there is a problem that the space between the tips of both lids spreads.
[0006]
[Problems to be solved by the invention]
The present invention was invented in view of the problems of the conventional example described above, and even if water enters from a gap between the rising piece and the outer surface of the lower end of the side plate, this water enters the folding container. In addition, it is possible to reliably prevent water from entering into the inside from the overlapping portion of the tips of the two lids. Further, when the lids are closed, the gap between the tips of the lids is increased. It is an object of the present invention to provide a folding container that can be avoided.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems of the present invention, the folding container of the present invention includes a bottom plate 2 having a rectangular shape in plan view, with a rising piece 1 projecting upward on the outer periphery, and an upper frame 3 having a rectangular shape in plan view. The pair of long side plates 4 whose upper end is pivotally supported by the upper frame 3 and whose lower end is pivotally supported by the bottom plate 2, and one end of the upper end or the lower end is the upper side. A pair of short side plates 5 that are pivotally supported by either the frame 3 or the bottom plate 2 and are folded inward on the bottom plate 2 in the folded state. The side plates 5 on the side are overlapped, the side plates 4 on both long sides are erected and the side plates 5 on both short sides are erected. A folding container 6 in which the outer surface of the lower end of the side plate 5 stands along the inside of the rising piece 1 of the bottom plate 2. Te, along the inside periphery to the rising piece 1 of the upper surface portion of the bottom plate 2 to form a drainage ditch 7, the drain portion 7a for drainage to the outside in communication with the drainage grooves 7 provided to the plan view rectangular shape The door body 8 is rotatably attached to the two opposite sides of the upper frame 3, the front end portions of the pair of door bodies 8 are overlapped, and the lower overlap portion 9 is overlapped at the overlapping portion of the front end portions of the pair of door bodies 8. A drainage ditch portion 11 having a discharge portion 10 to the outside is formed on the upper surface portion at the end portion . By adopting such a configuration, even when water enters between the rising piece 1 and the side plate 4 on the long side or between the rising piece 1 and the side plate 5 on the short side, the upper surface portion of the bottom plate 2 It can flow along a drainage groove 7 formed along the inside of the rising piece 1 and drain to the outside from the drainage part 7 a, and does not enter the folding container 6. Further, the pair of lids 8 are closed and the upper overlapping part 12 of the other lid 8 is stacked on the lower overlapping part 9 of one lid 8. Even if water permeates into the overlapping portion of the lower overlapping portion 9, water can flow along the drainage recessed groove portion 11 formed on the upper surface portion of the lower overlapping portion 9 and drain to the outside from the discharge portion 10 at the end portion. It is designed not to invade.
[0009]
Further, it is also preferable that a fitting hanging piece 13 protrudes from the upper overlapping portion 12 and that the fitting hanging piece 13 is biased toward the side surface close to the distal end side of the lower overlapping portion 9 of the drain groove 11. By adopting such a configuration, it is possible to prevent the fitting between the pair of door bodies 8 from being inserted into the drainage groove portion 11 of the fitting hanging piece 13, and the fitting hanging. Even if the piece 13 is fitted into the drain groove 11, the fitting hanging piece 13 is biased and fitted to the side surface near the distal end side of the lower overlap portion 9 of the drain groove 11, so that Water that has entered the overlapping portion with the upper overlapping portion 12 does not hinder the flow of water in the drain groove portion 11, and the fitting drooping piece 13 that is inserted into the drain groove portion 11 further exceeds that of the water. Intrusion of water is prevented.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below based on embodiments shown in the accompanying drawings. As shown in FIGS. 3 to 8, the folding container 6 of the present invention includes a bottom plate 2 having a rectangular shape in plan view, an upper frame 3 having a rectangular shape in plan view, an upper plate portion 15, and a lower plate portion 16.
