以下、実施例によって本発明の実施形態を説明する。   Hereinafter, embodiments of the present invention will be described by way of examples.

図１は実施例１の食品包装用容器１の斜視図であり、図２は実施例１の食品包装用容器１の平面図である。
また、図３は図２のＡ−Ａ線断面図であり、図４は実施例１の食品包装用容器１の縁枠２の平面図である。
食品包装用容器１は、折り畳み可能で開いた時に直方体状となる縁枠２と、薄いプラスチック製で一体成形により作製された容器３からなり、図１及び３に示すように、直方体状とした縁枠２の上から容器３を落とし込み、縁枠２の上縁４に容器３の上方外縁５を被せることによって組み立てられるようになっている。
さらに、図３に示すように、縁枠２の内側には上縁４に沿って平行に溝６が設けてあるとともに、容器３の側壁７の外側には上方外縁５に沿って平行に突条８が設けてある。
そして、縁枠２の上縁４に容器３の上方外縁５を被せると、溝６に突条８が嵌合するので、食品包装用容器１を組み立てた後には縁枠２と容器３が分離しにくくなる。 FIG. 1 is a perspective view of the food packaging container 1 of the first embodiment, and FIG. 2 is a plan view of the food packaging container 1 of the first embodiment.
3 is a cross-sectional view taken along the line AA of FIG. 2, and FIG. 4 is a plan view of the edge frame 2 of the food packaging container 1 of the first embodiment.
The food packaging container 1 is composed of an edge frame 2 that can be folded and formed into a rectangular parallelepiped shape when opened and a container 3 that is made of thin plastic and integrally formed, and has a rectangular parallelepiped shape as shown in FIGS. The container 3 is dropped from above the edge frame 2, and the upper edge 4 of the edge frame 2 is put on the upper outer edge 5 of the container 3 to be assembled.
Further, as shown in FIG. 3, a groove 6 is provided inside the edge frame 2 in parallel along the upper edge 4, and protrudes in parallel along the upper outer edge 5 on the outside of the side wall 7 of the container 3. Article 8 is provided.
When the upper outer edge 5 of the container 3 is put on the upper edge 4 of the edge frame 2, the protrusion 8 is fitted into the groove 6, so that the edge frame 2 and the container 3 are separated after the food packaging container 1 is assembled. It becomes difficult to do.

縁枠２は、発泡プラスチックの板を環状に接続したものであり、図４に示すように、直方体状としたとき一方の対角線上に位置する隅部には２つのＶ字状の溝９が設けてあるとともに、他方の対角線上に位置する隅部には多数の楔状の溝１０が設けてある。
そのため、縁枠２は２つのＶ字状の溝９を設けた隅部において折り畳まれ、多数の楔状の溝１０を設けた隅部が１８０°に広げられて、対向する内面同士が密着し、発泡プラスチックの板を２枚重ねた状態にすることが可能となっている。
また、縁枠２は開いた時に回転対称形となるので、容器３を落とし込む際に、方向性を気にすることなく組み立てることができる。 The edge frame 2 is formed by connecting foamed plastic plates in an annular shape. As shown in FIG. 4, when the rectangular frame is formed, two V-shaped grooves 9 are formed at corners located on one diagonal line. In addition, a number of wedge-shaped grooves 10 are provided at corners located on the other diagonal line.
Therefore, the edge frame 2 is folded at the corner provided with the two V-shaped grooves 9, the corner provided with a large number of wedge-shaped grooves 10 is expanded to 180 °, and the inner surfaces facing each other are in close contact with each other. It is possible to put two sheets of foamed plastic on each other.
Further, since the edge frame 2 is rotationally symmetric when opened, it can be assembled without worrying about directionality when the container 3 is dropped.

容器３は、大きな食品収納用凹部１１と小さな食品収納用凹部１２を有し、図１及び２に示すように、一方の対角線上に位置する隅部の内側には短めの突起１３、他方の対角線上に位置する隅部の内側には長めの突起１４が設けてある。
これらの突起１３、１４は、食品包装用容器１を積み重ねた時、上方にある縁枠２の下部の内側に嵌って、上下の食品包装用容器１がずれるのを抑える機能を有している。 The container 3 has a large food storage recess 11 and a small food storage recess 12, and as shown in FIGS. 1 and 2, a short projection 13 is formed inside the corner located on one diagonal line, and the other A long protrusion 14 is provided inside the corner located on the diagonal line.
When the food packaging containers 1 are stacked, these protrusions 13 and 14 are fitted inside the lower portion of the upper edge frame 2 and have a function of preventing the upper and lower food packaging containers 1 from shifting. .

長めの突起１４が設けてある隅部の側壁には、図１〜３に示すように、食品収納用凹部１１、１２の底面から突起１４の上縁まで、他の側壁部分よりなだらかな傾斜となっている緩斜面部１５が設けてある。
この緩斜面部１５は、底面の中央寄りから徐々に立ち上がり、途中から約６０°の傾斜角を保って突起１４の上縁に達しており、その幅は底面側ほど広く上縁側ほど狭くなっている。
このような構造の食品収納用凹部１１又は１２によれば、流動性の高い食品が収納されている場合に、突起１４が設けてある隅部が低くなるように食品包装用容器１を傾けると食品は緩斜面部１５に集まり、食品包装用容器１をさらに傾けると食品が突起１４の上縁側に導かれるので、突起１４の上縁から食品を直接口に流し込んだり、箸を底面側から突起１４の上縁側に移動させることで突起１４の上縁から食品を掻き込んだりし易い。
そして、突起１４は、流動性の高い食品を上縁側に導く際に食品を角部に集中させるように機能するので、食品が外側にこぼれ落ちるのを防ぐ効果がある。 As shown in FIGS. 1 to 3, the side wall of the corner where the long protrusion 14 is provided has a gentle slope from the bottom surface of the food storage recesses 11, 12 to the upper edge of the protrusion 14 than the other side wall portions. A gentle slope 15 is provided.
The gentle slope portion 15 gradually rises from the center of the bottom surface, reaches the upper edge of the protrusion 14 while maintaining an inclination angle of about 60 ° from the middle, and the width is wider toward the bottom surface side and narrower toward the upper edge side. Yes.
According to the food storage recess 11 or 12 having such a structure, when food with high fluidity is stored, when the food packaging container 1 is tilted so that the corner where the protrusions 14 are provided is lowered. The food gathers on the gentle slope 15 and the food packaging container 1 is further tilted so that the food is guided to the upper edge side of the protrusion 14 so that the food can be poured directly into the mouth from the upper edge of the protrusion 14 or the chopsticks protrude from the bottom side. It is easy to scrape food from the upper edge of the protrusion 14 by moving it to the upper edge side of the protrusion 14.
And since the protrusion 14 functions to concentrate the food at the corner when the highly fluid food is guided to the upper edge side, there is an effect of preventing the food from spilling outside.

図５は実施例２の食品包装用容器２１の斜視図、図６は実施例２の食品包装用容器２１の平面図、図７は図６のＡ−Ａ線断面図である。
なお、実施例２の食品包装用容器２１の縁枠２２は、実施例１の縁枠２と同様の構造であるので、その平面図及び詳細な説明は省略する。
食品包装用容器２１の容器２３も、材質や製法は実施例１の容器３と同様であり、食品包装用容器２１を組み立てる際には、図５及び７に示すように、直方体状とした縁枠２２の上から容器２３を落とし込み、縁枠２２の上縁２４に容器２３の上方外縁２５を被せれば良く、そうすることによって縁枠２２の内側に設けてある溝２６に容器２３の側壁２７に設けてある突条２８が嵌合するので、食品包装用容器２１を組み立てた後には縁枠２２と容器２３が分離しにくくなる。 5 is a perspective view of the food packaging container 21 of the second embodiment, FIG. 6 is a plan view of the food packaging container 21 of the second embodiment, and FIG. 7 is a cross-sectional view taken along line AA of FIG.
In addition, since the edge frame 22 of the container 21 for food packaging of Example 2 is the same structure as the edge frame 2 of Example 1, the top view and detailed description are abbreviate | omitted.
The container 23 of the food packaging container 21 is similar in material and manufacturing method to the container 3 of the first embodiment. When the food packaging container 21 is assembled, as shown in FIGS. The container 23 may be dropped from above the frame 22 and the upper edge 24 of the edge frame 22 may be covered with the upper outer edge 25 of the container 23, so that the side wall of the container 23 is placed in the groove 26 provided inside the edge frame 22. Since the protrusion 28 provided in 27 is fitted, it is difficult to separate the edge frame 22 and the container 23 after the food packaging container 21 is assembled.

容器２３は、大きな食品収納用凹部３１と小さな食品収納用凹部３２を有し、図５及び６に示すように、一方の対角線上に位置する隅部の内側に突起３３が設けてある。
これらの突起３３は、食品包装用容器２１を積み重ねた時、上方にある縁枠２２の下部の内側に嵌って、上下の食品包装用容器２１がずれるのを抑える機能を有している。
また、底面と側壁の境界部は、実施例１と異なり角部ができないように曲面状となっている。 The container 23 has a large food storage recess 31 and a small food storage recess 32, and as shown in FIGS. 5 and 6, a protrusion 33 is provided inside a corner located on one diagonal line.
When the food packaging containers 21 are stacked, these protrusions 33 have a function of being fitted inside the lower portion of the upper edge frame 22 to prevent the upper and lower food packaging containers 21 from being displaced.
Further, unlike the first embodiment, the boundary between the bottom surface and the side wall has a curved surface so as not to have a corner.

突起３３の設けられていない隅部の側壁には、図５及び６に示すように、食品収納用凹部３１、３２の底面から隅部の上縁まで、他の側壁部分よりなだらかな傾斜となっている緩斜面部３５が設けてある。
この緩斜面部３５は、底面の中央寄りから徐々に立ち上がり、途中から約６０°の傾斜角を保って隅部の上縁に達しており、その幅は底面側ほど広く上縁側ほど狭くなっている。
このような構造の食品収納用凹部３１又は３２によれば、流動性の高い食品が収納されている場合に、緩斜面部３５が設けてある隅部が低くなるように食品包装用容器２１を傾けると食品は緩斜面部３５に集まり、食品包装用容器２１をさらに傾けると食品が隅部の上縁側に導かれるので、隅部の上縁から食品を直接口に流し込んだり、箸を底面側から隅部の上縁側に移動させることで隅部の上縁から食品を掻き込んだりし易い。
また、実施例１と異なり底面と側壁の境界部は、角部ができないように曲面状となっているので、食品をスプーンやレンゲですくい取り易いという効果がある。 As shown in FIGS. 5 and 6, the side wall of the corner portion where the protrusion 33 is not provided has a gentler slope than the other side wall portions from the bottom surface of the food storage recesses 31 and 32 to the upper edge of the corner portion. A gentle slope 35 is provided.
The gentle slope 35 gradually rises from the center of the bottom surface and reaches the upper edge of the corner while maintaining an inclination angle of about 60 ° from the middle, and the width is wider toward the bottom side and narrower toward the upper edge side. Yes.
According to the food storage recess 31 or 32 having such a structure, when food with high fluidity is stored, the food packaging container 21 is arranged so that the corner provided with the gentle slope portion 35 is lowered. When the food is tilted, the food gathers on the gentle slope 35, and when the food packaging container 21 is further tilted, the food is led to the upper edge of the corner. It is easy to scrape food from the upper edge of the corner by moving it from the upper edge to the corner.
Moreover, since the boundary part of a bottom face and a side wall is curved so that a corner | angular part cannot be made unlike Example 1, there exists an effect that it is easy to scoop a food with a spoon or a lotus root.
