Description

【０００１】
【発明の属する技術分野】
本発明は、各種物品の運搬，保管等に使用される合成樹脂製の折り畳みコンテナに関するものである。
【０００２】
【従来の技術】
折り畳みコンテナには、例えば実用新案登録第２５８９１６６号に示されたように、底板と重合する上枠に四側壁の側板を夫々内側に傾倒し得るように枢着したものが知られているほか、特開２００１−１３０５５３号に示されたように、底板の四側辺に側板を夫々内側に傾倒し得るように枢着したものが知られている。
【０００３】
【発明が解決しようとする課題】
ところで、搬送ラインが自動化された各種組立工場等では、通常の運搬用コンテナですでに実施されているように、この種の折り畳みコンテナにもその内容物を表示するためのカード差しを設けたり、バーコードが表示され、機械的に識別できるようにしたいという要望がある。
【０００４】
しかしながら従来の上記折り畳みコンテナでは、折り畳んだ状態では側板が内側へ倒されているのでカード差しやバーコードが見られず、カード差しやバーコードがどの側板にあるのかも判らないので、コンベヤ上に方向がまちまちで乗せられてしまい、自動で組み立てられても識別が不能になるおそれがあった。特に多数が段積みされた場合は識別が困難であった。このため上記折り畳みコンテナでは、やむを得ず両側にカード差しやバーコードを表示することもあった。
【０００５】
また、コンテナの色によって内容物を外から識別できるようにしたいという要望もあるが、折り畳みコンテナの場合は一体成形のコンテナと異なり四側壁の側板が底板と別体であり構成するパーツの数が多いために、内容物に応じて多種の色分けをしようとすると成形コストが掛るという問題があった。
本発明は、上述に鑑みてなされたもので、識別が容易なる折り畳みコンテナを低コストにて提供できるようにするものである。
【０００６】
【課題を解決するための手段】
そのために本発明は、底板または該底板と重合する上枠に四側壁の側板が内側に傾倒し得るように枢着された合成樹脂製の折り畳みコンテナであって、前記底板，上枠，側板のうちのいずれかのパーツを他のパーツと色相の異なる合成樹脂材料にて成形してなることを特徴とする。
また本発明は、底板または該底板と重合する上枠に四側壁の側板が内側に傾倒し得るように枢着され該側板の表面には内容物を表示するためのカードが止着される合成樹脂製の折り畳みコンテナであって、前記底板，上枠，側板のうちのいずれかのパーツを互いに色相の異なる合成樹脂材料にて前記カードが表示された側は色相が異なるように略半部ずつ成形してなることを特徴とする。
また本発明は、底板または該底板と重合する上枠に四側壁の側板が内側に傾倒し得るように枢着され該側板の表面には内容物を表示するためのカードが止着される合成樹脂製の折り畳みコンテナであって、該底板または上枠を互いに色相の異なる合成樹脂材料にて前記カードが表示された側は色相が異なるように略半部ずつ成形してなることを特徴とする。
【０００７】
【発明の実施の形態】
次に図面に従い本発明の実施の形態を説明する。図１は本発明に係るコンテナの斜視図、図２はその折り畳み途中の斜視図、図３は折り畳み時の斜視図である。図中、１は長方形状の底板、２は該底板の長側辺に下縁が枢着され軸部３によって内向きにく字状に折れ曲り可能なるように設けられた側板、４は該側板２の上縁が枢着された長方形状の上枠、５は該上枠の短側辺に内側に傾倒可能なるように枢着された側板である。なお、６は該側板５の表面に止め具７によって止着したカードである。
【０００８】
上記底板１，側板２，５，上枠４はいずれも合成樹脂の射出成形によるが、上枠４に関しては左右半部分毎に色相の異なる合成樹脂を使用し、いわゆる２色成形とする。このように上枠４の色相を左右で異ならせることで、図３に示したように折り畳んだ状態としてもこのコンテナにおける上記カード６が表示された側を識別することができる。
【０００９】
一方、図４に示したコンテナは、底板１の四側辺に側板２，５を夫々内側に傾倒可能に枢着し、側板５の表面に止め具７によってカード６を止着してなるもので、この実施形態に示すコンテナでは、底板１を２色成形することで、図５に示したように折り畳んだ状態としても側方からこのコンテナにおける上記カード６が表示された側を容易に識別することができる。
【００１０】
また、図６に示した実施形態は、上枠４の外側面に該上枠とは色違いの識別ピース８を固着してなるもので、該識別ピース８は図７に示したように裏面に突設された膨縮ピン９を上枠４に開設された取付孔１０に差し込んで固着される。このため、このコンテナを折り畳んだときこの識別ピース８によってもカード６が表示された側を識別することができる。なお、該識別ピース８は底板１の外側面に固着してもよい。
【００１１】
また、図８に示した本発明の他の実施形態は、上枠４を四側壁の側板２，５とは色違いの合成樹脂材料にて成形してなるもので、このように上枠４の色相を他のパーツと異なるようにすれば折り畳んだ状態でも色識別が可能であるので、その他のパーツである底板１，側板２，５等は共用しても、用途や内容物等に応じて多種のコンテナを容易に製造することが可能となり、識別を容易とする多種のコンテナを低コストで製造することができる。また、図示しないが、同様の趣旨で底板１や側板２または側板５を他のパーツの色相と異ならしめてもよい。
【００１２】
【発明の効果】
このように本発明は、底板，上枠，側板のうちのいずれかのパーツを互いに色相の異なる合成樹脂材料にてカードが表示された側は色相が異なるように略半部ずつ成形し、また底板または上枠を互いに色相の異なる合成樹脂材料にてカードが表示された側は色相が異なるように略半部ずつ成形することで、折り畳んだ状態でもカードやバーコード等が表示された側を容易に識別ができるようになり、折り畳み状態のままで機械的に搬送方向が揃えられるなど、搬送ラインを自動化するのに顕著な効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin folding container used for transportation and storage of various articles.
[0002]
[Prior art]
For example, as shown in Utility Model Registration No. 2589166, the folding container is known to be pivotally attached so that the side plates of the four side walls can be tilted inward to the upper frame overlapping with the bottom plate, As disclosed in Japanese Patent Laid-Open No. 2001-130553, there is known one in which side plates are pivotally attached to four sides of a bottom plate so as to be inclined inward.
[0003]
[Problems to be solved by the invention]
By the way, in various assembly factories where the transfer line is automated, a card holder for displaying the contents of this type of folding container is also provided, as is already done in normal shipping containers, There is a desire to display a bar code so that it can be mechanically identified.
[0004]
However, in the above-mentioned conventional folding container, it showed no card insertion and bar code since the side plate is brought down to the inside in the folded state, since the card insertion and bar code is not known even if there's any side plate, onto the conveyor There is a possibility that the direction is mixed and the identification becomes impossible even if it is automatically assembled. In particular, it was difficult to distinguish when many were stacked. For this reason, in the above folding container, card insertion and a barcode are sometimes displayed on both sides.
[0005]
In addition, there is a desire to be able to distinguish the contents from the outside by the color of the container, but in the case of a folding container, unlike the integrally molded container, the side plates on the four side walls are separate from the bottom plate, and the number of parts to be configured is For this reason, there has been a problem in that molding costs are incurred if various colors are classified according to the contents.
The present invention has been made in view of the above, and makes it possible to provide a folding container that can be easily identified at low cost.
[0006]
[Means for Solving the Problems]
To this end, the present invention is a synthetic resin folding container that is pivotally attached to a bottom plate or an upper frame that overlaps with the bottom plate so that the side plates of the four side walls can be tilted inward, and includes the bottom plate, the upper frame, and the side plate. Any one of the parts is formed of a synthetic resin material having a hue different from that of the other parts.
Further, the present invention is a composite in which the side plate of the four side walls is pivotally attached to the bottom plate or the upper frame overlapping with the bottom plate so that the side plate can tilt inward, and the card for displaying the contents is fixed to the surface of the side plate. A plastic folding container, in which one of the parts of the bottom plate, the top frame, and the side plate is made of synthetic resin materials having different hues on the side on which the card is displayed so that the hues are substantially different from each other. It is formed by molding.
Further, the present invention is a composite in which the side plate of the four side walls is pivotally attached to the bottom plate or the upper frame overlapping with the bottom plate so that the side plate can tilt inward, and the card for displaying the contents is fixed to the surface of the side plate. A resin-made folding container, characterized in that the bottom plate or the top frame is formed of synthetic resin materials having different hues, and the side on which the card is displayed is molded approximately in half so that the hues are different. .

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a container according to the present invention, FIG. 2 is a perspective view in the middle of folding, and FIG. 3 is a perspective view in folding. In the figure, 1 is a rectangular bottom plate, 2 is a side plate provided so that a lower edge is pivotally attached to the long side of the bottom plate and can be bent inwardly by a shaft portion 3, A rectangular upper frame 5 on which the upper edge of the side plate 2 is pivotally attached is a side plate pivotally attached to the short side of the upper frame so as to be tiltable inward. Reference numeral 6 denotes a card fixed to the surface of the side plate 5 by a stopper 7.
[0008]
The bottom plate 1, the side plates 2, 5, and the upper frame 4 are all formed by synthetic resin injection molding. However, the upper frame 4 is made of so-called two-color molding using synthetic resins having different hues for the left and right half portions. Thus, by making the hue of the upper frame 4 different on the left and right, the side on which the card 6 is displayed in this container can be identified even in the folded state as shown in FIG.
[0009]
On the other hand, the container shown in FIG. 4 is such that side plates 2 and 5 are pivotally attached to the four sides of the bottom plate 1 so as to be tilted inward, and a card 6 is fixed to the surface of the side plate 5 by a stopper 7. In the container shown in this embodiment, the bottom plate 1 is molded in two colors, so that the side on which the card 6 is displayed can be easily identified from the side even when folded as shown in FIG. can do.
[0010]
In the embodiment shown in FIG. 6, an identification piece 8 of a different color from the upper frame is fixed to the outer surface of the upper frame 4, and the identification piece 8 is a back surface as shown in FIG. The expansion / contraction pin 9 projecting from is inserted into the mounting hole 10 formed in the upper frame 4 and fixed. For this reason, the side on which the card 6 is displayed can be identified by the identification piece 8 when the container is folded. The identification piece 8 may be fixed to the outer surface of the bottom plate 1.
[0011]
Further, in another embodiment of the present invention shown in FIG. 8, the upper frame 4 is formed of a synthetic resin material having a different color from the side walls 2 and 5 of the four side walls. By making the hue of this part different from that of other parts, it is possible to identify the color even in the folded state, so other parts such as the bottom plate 1, side plates 2, 5, etc. can be shared, but depending on the application and contents Therefore, various containers can be easily manufactured, and various containers that facilitate identification can be manufactured at low cost. Although not shown, the bottom plate 1, the side plate 2, or the side plate 5 may be made different from the hue of other parts for the same purpose.
[0012]
【The invention's effect】
As described above, according to the present invention, any one of the bottom plate, the top frame, and the side plate is molded approximately in half so that the side on which the card is displayed with a synthetic resin material having a different hue is different in hue. The side on which the card is displayed on the bottom plate or the upper frame with synthetic resin materials having different hues is formed in half so that the hue is different, so that the side on which the card, barcode, etc. are displayed even when folded This makes it possible to easily identify, and there is a remarkable effect in automating the transport line, such as mechanically aligning the transport direction in the folded state.
