Description

【0001】
【発明の属する技術分野】
本発明は、食品や食器等を収める箱型の容器本体を有し、容器本体は入れ子式に積み重ね可能に構成されているプラスチック製運搬容器に関するものである。
【0002】
【従来の技術】
この種のプラスチック製運搬容器は、食品工場や厨房その他各方面において使用され、日常頻繁に食品等の運搬に使用されるものであるので、軽量かつ丈夫であることが要求される。そのため容器本体の要所をリブなどで補強し、必要な強度を持たせた構造を有している。しかし、補強構造を随所に必要とするので、リブが非常に多くなり、汚れ勝ちになるのは避けられないという問題を持つことになる。
【0003】
図13によりこの点を説明する。図中aは容器本体、bはリブを示しており、このリブbは要所要所に多数設けられている。このため、リブ面に液が付着したり埃が溜まったりするので、定期に洗浄の必要を生じる。しかしながら、リブの付け根cに付着した汚れは洗浄しても落ちにくく、細菌などが繁殖する可能性もある。食品等を扱う運搬容器として、汚れが大敵であるのはいうまでもない。
【0004】
これに対して、リブbに水平垂直交差を少なくし、リブ構成面の接合角度dを大きくとったり、凹角部における角アールeを大きくすることも考えられる。ところが、これでは部分的に肉厚が増し、成形品の肉引けfを生じたり、射出成形品の生産性を低下させるなどの問題点が発生する。
【0005】
【発明が解決しようとする課題】
本発明は前記の点に着目してなされたものであり、その課題は、在来のリブ構造を使用することなく必要な構造強度を満足し、しかも肉引けや生産性低下などの問題を生じない食品、食器などのプラスチック製運搬容器を提供することである。また本発明の他の課題は、この種のプラスチック製運搬容器の洗浄性と洗浄効率を向上させることである。
【0006】
【課題を解決するための手段】
前記の課題を解決するため、本発明は、食品や食器等を収める箱型の容器本体を有し、容器本体は入れ子式に積み重ね可能に構成するとともに、積み重ね深さを規定するために相互に係合可能な係合手段の一方を容器本体の内側面に設け、係合手段の他方を容器本体の外側面に設けたプラスチック製運搬容器について、係合手段を構成する係合凸部とそれに係合可能な係合凹部を設けるとともに、要部を中空に形成するという手段を講じたものである。
【0007】
本発明のプラスチック製運搬容器は、食品や食器等を収めるものであり、箱型の容器本体を有している。容器本体は入れ子式に積み重ね可能とするために、開口部よりも底部の方がやや小型になっているか、或いは開口部側から底部側へ向かってテーパー状になる側面から成り立っている。さらに、積み重ね深さを規定するために、相互に係合可能な係合手段の一方を容器本体の内側面に設け、係合手段の他方を容器本体の外側面に設けている。
【0008】
係合手段は、係合凸部と係合凹部とから成るものとし、容器本体の内側面においてへこんでいるものを係合凹部とし、容器本体の外側面において出っ張っているものを係合凸部とする。係合凹部は容器本体の開口部から始まり、その下端は容器本体の内側面において底部まで達するか或いは達することなく途中で終わる位置に設定され、係合凸部は容器本体の下部から始まり、係合凹部の下端に突きあたるように設けられている。
【0009】
係合凸部と係合凹部の容器本体における平面配置が対称であれば、容器本体の向きに関係なく係合凸部と係合凹部とが係合するので、上下の容器本体は常に入れ子式に積み重ねられるが、係合凹部と係合凸部の上記平面配置を非対称にすることにより、向きが一致する場合には入れ子式積み重ねとなり(図11参照)、向きが逆になる場合には非入れ子式の、いわゆる段積み状の積み重ねとなる(図12参照)。
【0010】
なお、容器本体を非入れ子式に積み重ねる場合において、上位の容器本体の下部が、下位の容器本体の開口部の縁に係合するように、段部を係合凸部の下端にも設けると、積み重ね状態でより安定する。この段部は、上位の容器本体の下部が、僅かに下位の容器本体の開口部内に入るのを許し、かつまた上位、下位の容器本体のずれを制限する。
【0011】
これらの、係合手段を有する容器本体の要部は中空構造となっていて、リブを必要としないように構成されている。中空構造は、容器本体の縁枠、側面及び底面等に設けることができる。容器本体は射出成形によって製造される射出成形品とするが、これに中空構造を具備させるためには、射出中空成形によって成形することが望ましい。このための技術としては、特公昭57−14968号をはじめとするAGI成形(旭化成工業(株)の商品名)などの方法を適用することができる。
【0012】
さらに、係合凸部と係合凹部とは、夫々の凹角部において、凹角部を構成する2面の接合角度を鈍角にするか、或いは上記2面の接合部における角アールを大きく取るようにする。本発明では凹角部をへこんだ角(かど)という意味で使用している。2面の接合角度を鈍角にした上で、2面の接合部における角アールを大きく取るようにすればさらに良い。これらは汚れ付着を防止する目的である。
【0013】
【発明の実施の形態】
以下図示の実施形態を参照して、本発明をより詳細に説明する。図において、11は比較的浅い箱型の容器本体を示しており、下部が上部よりもやや小型で、積み重ねると下位の容器本体の開口部12から内部へ上位の容器本体を入れ子式に収めることができるような基本構造を有している。開口部12は縁枠13が額縁状に取り囲んでおり、縁枠13は中空構造19を有している(図5参照)。
【0014】
また中空構造は、容器本体11の側面14にも、底部15に設けることができそれらの中空構造は可能な限り相互に有機的な関連性を持つことが望ましい。底部15には、格子状の肉抜き構造16を有している。肉抜き構造16は下面に露出しており、ここでは補強リブ構造を有している。しかし、全リブが下向きであり、汚れを付着させない構造となっている。
【0015】
容器本体11を入れ子式に積み重ね可能とするとともに、積み重ね深さを規定するために、係合凹部21が、容器本体11の内側面に開口部12から下方へ所要の長さで設けられており、また係合凹部21に係合可能な係合凸部22が容器本体11の外側面に、設けられている。係合凹部21の深さは凹部底23の位置で決まり、そこには係合凸部22の下面24が接し得る。
【0016】
さらに容器本体11を非入れ子式に積み重ねる場合において、上位となる容器本体11の下部が、下位になる容器本体11の縁枠13に係合するように、段部25を、係合凸部22の下端に設ける。段部25は、縁枠13の内側に容器本体下部をはまり込ませるとともに、はまり込んだ状態でずれを制限し、上位の容器本体11が下位の容器本体11の内部へ落ち込むのを防ぐための大きさを有している(図12参照)。
【0017】
例示してある係合凹部21はへこみの深いものと浅いものとの2種類から成るので、これらに係合可能な係合凸部22も出っ張りの大きいものと小さいものとの2種類から成る。また深い係合凹部21にも、幅の狭いものと広いものとを設けている。これに応じて係合凸部22には幅の狭いものと広いものとを設けている。浅い係合凹部21は容器本体11の内部4隅に配置してあり、深い係合凹部21は浅い係合凹部21の左右両隣に配置してあり、出っ張りの大きいものと小さいものから成る係合凸部22も同様に配置されているので、バランス良く積み重ねて荷重を負担することができるようになっている。
【0018】
この係合凹部21には幅の広狭に拘ず縦の中空構造29を設けている(図6、7、10及び12参照)。このため縁枠13につながった直交方向下方へ縦の中空構造29が延びて底部肉抜き構造16と連絡する。縦の中空構造29は、従って、容器本体11の4隅に少なくとも2箇所ずつ設けられ、全体の構造強度を向上させることとなる。さらに底部15の肉抜き構造の中にも、中空部分39を設けることができる。
【0019】
そして、これらの係合凹部21(必然的に係合凸部22についても同様)の容器本体11における平面配置は非対称にする(図3参照)。ここで非対称とは、容器本体11の向きを左右逆にすると入れ子式の積み重ねができなくなるような非対称性を指す。図3を参照すると、この平面形は左右非対称、上下対称ということになると考えて良く、また360度回転対称といっても良い。
【0020】
このような本発明のプラスチック製運搬容器10は、前記の射出中空成形技術により、縁枠13や係合凹部21及び係合凸部22の必要な箇所の成形品板厚を厚肉にしてガス注入を行い中空構造19、29を形成する。図10は成形中の段階を示しており、特に本発明の場合には、係合凸部22と係合凹部21等の凹角部における2面の接合角度Aを鈍角とし、また2面の接合部における角アールRを可能な限り大きくするということも行っている。接合角度Aは、通常2〜3度に設定する抜け勾配よりも大きい鈍角つまり95度〜120までの範囲が良く、また角アールRは、通常0.5mm程度に設定する値よりも数倍以上大きい値に設定(例えば1.0〜5mm程度)する。
【0021】
容器本体11には、さらに、把手に当たる部分17が前後左右の縁枠13の一部を利用して設けられており、この部分は中空ではあるが、密閉構造にはしていない。しかし同部分17には小孔18を設けて内外を通じさせ、把手に当たる部分17のへこみに水やごみなどが溜まらないようになっている。
【0022】
本発明のプラスチック製運搬容器10は、下位容器本体11の係合凹部21と上位容器本体11の係合凸部22との配置を一致させて積み重ねることにより、上位のものが下位のものの内部に入り込んでいる入れ子式の積み重ねを可能とする。図11の状態である。よって上下容器本体間の空間26は狭くて良いから、いわゆるスタッキングができる。下位容器本体11の係合凹部21と上位容器本体11の係合凸部22との配置が一致しない向きに積み重ねると、上位のものの段部25が内部に殆ど入り込まず、下位のものの縁枠13上に乗る非入れ子式の積み重ねとなる。図12の状態である。この場合上下容器本体間の空間26は容器本体1個分が確保され、しかも上位の容器本体が下部の容器本体内へずれ落ちることがないのでいわゆるネスティングができ、内部に食品や食器等を収めたまま運搬可能である。
【0023】
【発明の効果】
本発明は以上の如く構成されかつ作用するものであるから、在来のリブ構造をを使用しなくても必要な強度を得ることができ、リブ構造に起因する汚れやすさという問題が解決され、また、汚れを洗浄する必要がある場合でもリブ構造のような洗浄しにくさがないので洗浄効率が良く、より完全な洗浄が可能となる。また、偏肉やそれに基づく肉引きのおそれもないので高品質の製品を提供でき、生産性低下という問題も生じない。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a plastic transport container having a box-shaped container main body for storing food, tableware, and the like, and the container main body is configured to be nestable and stackable.
[0002]
[Prior art]
This kind of plastic transport container is used in food factories, kitchens, and other various fields, and is frequently used for transporting foods and the like on a daily basis. Therefore, it is required to be lightweight and strong. Therefore, it has a structure in which important parts of the container main body are reinforced with ribs or the like to give necessary strength. However, since the reinforcing structure is required everywhere, the number of ribs becomes very large, and there is a problem that it is inevitable that the ribs are liable to become dirty.
[0003]
This will be described with reference to FIG. In the figure, a indicates a container body, b indicates a rib, and a large number of the ribs b are provided at necessary places. For this reason, the liquid adheres to the rib surface or dust accumulates, so that periodic cleaning is required. However, the dirt attached to the base c of the rib is difficult to remove even when washed, and there is a possibility that bacteria and the like may propagate. Needless to say, dirt is a great enemy as a transport container for handling foods and the like.
[0004]
On the other hand, it is conceivable to reduce the horizontal and vertical intersections of the rib b and increase the joining angle d of the rib-constituting surface or increase the corner radius e at the concave corner. However, this causes problems such as a partial increase in the wall thickness, a reduction in the thickness of the molded product, and a decrease in the productivity of the injection molded product.
[0005]
[Problems to be solved by the invention]
The present invention has been made by paying attention to the above points, and the problem is to satisfy the required structural strength without using a conventional rib structure, and to cause problems such as thinning and reduction in productivity. There is no food, tableware etc. to provide plastic transport containers. Another object of the present invention is to improve the cleanability and cleaning efficiency of this type of plastic transport container.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention has a box-shaped container main body for storing food, tableware, and the like, and the container main body is configured to be nestable and stackable, and mutually defined to define a stacking depth. For a plastic transport container in which one of the engageable engaging means is provided on the inner side surface of the container body and the other of the engaging means is provided on the outer side surface of the container body, the engaging convex portion forming the engaging means and the Means is provided in which an engaging recess that can be engaged is provided and the main part is formed hollow.
[0007]
The plastic transport container of the present invention stores food, tableware, and the like, and has a box-shaped container main body. In order to be able to be stacked in a nesting manner, the container body has a slightly smaller bottom portion than the opening portion, or has a side surface that tapers from the opening side to the bottom side. Further, to define the stacking depth, one of the mutually engageable engaging means is provided on the inner surface of the container body, and the other of the engaging means is provided on the outer surface of the container body.
[0008]
The engaging means comprises an engaging convex portion and an engaging concave portion, the concave portion on the inner surface of the container body is defined as the engaging concave portion, and the convex portion on the outer surface of the container main body is defined as the engaging convex portion. And The engaging concave portion starts from the opening of the container main body, the lower end thereof is set to a position on the inner surface of the container main body that reaches the bottom or ends halfway without reaching the bottom, and the engaging convex portion starts from the lower portion of the container main body, It is provided so as to abut the lower end of the joint recess.
[0009]
If the planar arrangement of the engaging protrusion and the engaging recess in the container body is symmetrical, the engaging protrusion and the engaging recess engage regardless of the orientation of the container body, so the upper and lower container bodies are always nested. By arranging the above-mentioned plane arrangement of the engaging concave portion and the engaging convex portion to be asymmetric, a nested stack is formed when the orientations match, and a non-stacked stack is formed when the orientations are reversed. It is a so-called nested type stacking (see FIG. 12).
[0010]
In the case where the container bodies are stacked in a non-nested manner, a step is also provided at the lower end of the engaging projection so that the lower part of the upper container body is engaged with the edge of the opening of the lower container body. More stable in stacked condition. This step allows the lower part of the upper container body to enter slightly into the opening of the lower container body and also limits the displacement of the upper and lower container bodies.
[0011]
The main part of the container main body having the engagement means has a hollow structure, and is configured so as not to require a rib. The hollow structure can be provided on an edge frame, a side surface, a bottom surface, or the like of the container body. The container body is an injection-molded product manufactured by injection molding. In order to provide the container body with a hollow structure, it is desirable to mold the container by injection hollow molding. As a technique for this, a method such as AGI molding (trade name of Asahi Kasei Kogyo Co., Ltd.) such as Japanese Patent Publication No. 57-14968 can be applied.
[0012]
Further, the engaging convex portion and the engaging concave portion may be configured such that, at each of the concave corners, the joining angle of the two surfaces forming the concave corner is made obtuse or the corner radius at the joint of the two surfaces is made large. I do. In the present invention, a concave corner is used to mean a concave corner. It is even better if the joining angle of the two surfaces is made obtuse and the corner radius at the joining portion of the two surfaces is increased. These are for the purpose of preventing adhesion of dirt.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. In the figure, reference numeral 11 denotes a relatively shallow box-shaped container main body. The lower part is slightly smaller than the upper part, and when stacked, the upper container main body is nested inside from the opening 12 of the lower container main body. It has a basic structure that can be used. The opening 12 is surrounded by an edge frame 13 in a frame shape, and the edge frame 13 has a hollow structure 19 (see FIG. 5).
[0014]
Further, the hollow structure can be provided on the side surface 14 and the bottom portion 15 of the container main body 11, and it is desirable that the hollow structures have an organic relationship with each other as much as possible. The bottom portion 15 has a lattice-shaped lightening structure 16. The lightening structure 16 is exposed on the lower surface, and has a reinforcing rib structure here. However, all the ribs are directed downward, and the structure is such that dirt does not adhere.
[0015]
In order to allow the container main body 11 to be nested and stackable, and to define the stacking depth, an engaging recess 21 is provided on the inner side surface of the container main body 11 at a required length downward from the opening 12. An engagement projection 22 engageable with the engagement recess 21 is provided on the outer surface of the container body 11. The depth of the engaging concave portion 21 is determined by the position of the concave bottom 23, and the lower surface 24 of the engaging convex portion 22 can be in contact therewith.
[0016]
Further, when the container main bodies 11 are stacked in a non-nesting manner, the step 25 is formed with the engaging projections 22 so that the lower part of the upper container main body 11 is engaged with the edge frame 13 of the lower container main body 11. At the lower end of the The step portion 25 is used to fit the lower portion of the container main body inside the edge frame 13, limit the displacement in the fitted state, and prevent the upper container main body 11 from falling into the lower container main body 11. It has a size (see FIG. 12).
[0017]
The illustrated engaging recesses 21 are of two types, one having a deep dent and one having a shallow dent. Therefore, the engaging convex portions 22 engageable with these are also two types, one having a large protrusion and one having a small protrusion. Also, the deep engagement recess 21 is provided with a narrow one and a wide one. Accordingly, the engaging projection 22 is provided with a narrower one and a wider one. The shallow engaging recesses 21 are arranged at four inner corners of the container body 11, and the deep engaging recesses 21 are arranged on both left and right sides of the shallow engaging recess 21. Since the protrusions 22 are similarly arranged, they can be stacked and loaded with a good balance.
[0018]
This engaging recess 21 is provided with a vertical hollow structure 29 regardless of its width (see FIGS. 6, 7, 10 and 12). For this reason, a vertical hollow structure 29 extending downward in the orthogonal direction connected to the edge frame 13 communicates with the bottom lightening structure 16. Therefore, the vertical hollow structures 29 are provided at at least two places at each of the four corners of the container main body 11, thereby improving the overall structural strength. Further, a hollow portion 39 can be provided in the lightening structure of the bottom portion 15.
[0019]
Then, the planar arrangement of these engaging concave portions 21 (necessarily the same applies to the engaging convex portions 22) in the container body 11 is made asymmetric (see FIG. 3). Here, the term “asymmetric” refers to an asymmetry in which nested stacking is not possible if the direction of the container body 11 is reversed left and right. Referring to FIG. 3, this planar shape may be considered to be left-right asymmetric and vertical symmetry, and may also be referred to as 360-degree rotational symmetry.
[0020]
The plastic transport container 10 of the present invention can be formed by increasing the thickness of the molded product at the necessary positions of the edge frame 13 and the engagement concave portions 21 and the engagement convex portions 22 by the injection hollow molding technique described above. Injection is performed to form hollow structures 19 and 29. FIG. 10 shows a stage during molding. Particularly, in the case of the present invention, the joining angle A of the two surfaces at the concave corners such as the engaging convex portion 22 and the engaging concave portion 21 is set to an obtuse angle. It is also performed to make the corner radius R in the part as large as possible. The joining angle A is preferably an obtuse angle which is larger than the draft angle usually set at 2 to 3 degrees, that is, a range from 95 degrees to 120, and the angle R is several times or more than the value usually set at about 0.5 mm. It is set to a large value (for example, about 1.0 to 5 mm).
[0021]
The container body 11 is further provided with a portion 17 corresponding to a handle by utilizing a part of the front, rear, left and right edge frames 13, and this portion is hollow, but does not have a closed structure. However, a small hole 18 is provided in the portion 17 so as to allow the inside and outside to pass through, so that water, dust, and the like do not accumulate in the dent of the portion 17 that hits the handle.
[0022]
The plastic transport container 10 of the present invention is arranged such that the engagement concave portion 21 of the lower container main body 11 and the engagement convex portion 22 of the upper container main body 11 are aligned and stacked, so that the upper one is placed inside the lower one. Enables nested stacking. This is the state shown in FIG. Therefore, since the space 26 between the upper and lower container bodies may be narrow, so-called stacking can be performed. When the engagement concave portions 21 of the lower container main body 11 and the engagement convex portions 22 of the upper container main body 11 are stacked in a direction in which they do not coincide with each other, the step 25 of the upper container hardly enters the inside, and the edge frame 13 of the lower container It is a non-nested stack on top. This is the state shown in FIG. In this case, a space 26 between the upper and lower container main bodies is secured for one container main body, and the upper container main body does not slip down into the lower container main body, so that so-called nesting can be performed, and food, tableware and the like are stored inside. It can be transported as it is.
[0023]
【The invention's effect】
Since the present invention is configured and operates as described above, the required strength can be obtained without using a conventional rib structure, and the problem of easy contamination due to the rib structure is solved. In addition, even when it is necessary to clean dirt, there is no difficulty in cleaning such as a rib structure, so that the cleaning efficiency is good and more complete cleaning is possible. In addition, since there is no risk of uneven thickness or meat thinning based on the thickness, a high quality product can be provided, and there is no problem that productivity is reduced.
