Description
本発明は、容器ごと加熱してそのまま喫食可能な、容器入り冷凍食品に関する。 The present invention relates to a frozen food in a container that can be cooked as it is by heating the entire container.
近年の電子レンジの普及を受けて、電子レンジ加熱するだけで喫食可能な冷凍食品が多数販売されている。さらに、１つの容器内にご飯等の主食及び副食類などの複数の食品が配置されており、容器ごと電子レンジ加熱した後直ちに、又は簡単な作業のみで、見栄えよく盛り付けされた食品を提供することができる、容器入り冷凍食品も市販されている。 With the spread of microwave ovens in recent years, many frozen foods that can be eaten simply by heating in a microwave oven are being sold. In addition, a plurality of foods such as rice and other staple foods and side foods are arranged in one container, and the food that is nicely arranged is provided immediately after heating the whole microwave oven or only by simple work. Canned frozen foods are also commercially available.
しかし、上記の容器入り冷凍食品では、加熱後の見栄えを重視して容器内に各食品を配置する結果、食品全体としては厚みや密度に偏りが生じやすく、そのため、電子レンジ加熱の際に解凍ムラが起こりやすく、解凍不充分な部分や過加熱の部分があるなど喫食時の品質に劣ることがあった。また、該容器入り冷凍食品では、水分含量の異なる食品を並べて配置するため、冷凍保存中や解凍中に食品同士の間で水分移動が起こりやすく、これも品質低下の原因となっていた。特に、副食がソースなどの流動性のある食品の場合、解凍ムラや水分移動の問題は顕著であった。 However, in the above-mentioned frozen food in a container, as a result of placing each food in the container with an emphasis on the appearance after heating, the thickness and density of the food as a whole tends to be biased, so it is thawed when heated in a microwave oven. Unevenness is likely to occur, and there are cases where the quality at the time of eating is inferior, such as insufficiently thawed parts or overheated parts. In the frozen food in a container, since foods having different moisture contents are arranged side by side, moisture transfer easily occurs between the foods during frozen storage or thawing, which also causes quality deterioration. In particular, when the side food is a fluid food such as a sauce, the problems of thawing unevenness and moisture transfer are remarkable.
従来の電子レンジ加熱に適した容器入り冷凍食品として、例えば、特許文献１には、容器底部に冷凍した主固形食品が入れられ、その上部に、冷凍した調味液を載せた、側面上部周辺に小孔を設けた中蓋が載置され、さらに蒸気抜き孔を設けた上蓋が上面に嵌着されている、容器入り冷凍食品が開示されている。特許文献２には、容器内に、所定粘度に調製された調味液の上に主食が配置され、調味液と主食とが全面ではなく一部で接触して凍結されている冷凍食品が開示されている。また、特許文献３には、底壁と周壁を有する容器本体と、該容器本体の開口部近辺に支持された、多数の貫通孔を有する底壁を有する中皿とを備え、該容器本体に食品を収納し、該中皿にゼリー状スープを収納した電子レンジ用食品包装体が開示されている。 As a frozen food in a container suitable for conventional microwave heating, for example, in Patent Document 1, a frozen main solid food is placed at the bottom of the container, and a frozen seasoning liquid is placed on the top thereof. There is disclosed a frozen food in a container in which an inner lid provided with a small hole is placed and an upper lid provided with a vapor vent is fitted on the upper surface. Patent Document 2 discloses a frozen food in which a staple food is placed in a container on a seasoning liquid prepared to a predetermined viscosity, and the seasoning liquid and the staple food are partly contacted and frozen in part. ing. Patent Document 3 includes a container body having a bottom wall and a peripheral wall, and an inner dish having a bottom wall having a large number of through-holes supported in the vicinity of the opening of the container body. A food package for a microwave oven is disclosed in which food is stored and the jelly-like soup is stored in the inner dish.
本発明は、主食と副食を含む複数の食品をまとめて加熱することができ、さらに加熱後には、解凍ムラがなく、かつ主食と副食とが見栄えよく盛り付けられた食品を提供することができる容器入り冷凍食品を提供する。 The present invention can heat a plurality of foods including a staple food and a supplementary meal together, and can provide a food that has no thawing unevenness and is nicely arranged with the staple and supplementary foods after heating. Provide frozen foods.
本発明者らは、種々検討した結果、容器の底部に主食を、その上部に副食として凍結した流動性食品を収納し、その際に、該主食と副食とを、孔を有する隔壁で互いに接触しないように隔てて配置した容器入り冷凍食品を開発した。さらに本発明者らは、該容器入り冷凍食品を加熱すると、該加熱に伴って流動化した副食が徐々に該隔壁の孔から主食の上に流れ落ちることにより、加熱後には、解凍ムラがなく、かつ主食と副食とが見栄えよく盛り付けられた食品が得られることを見出した。 As a result of various studies, the inventors have stored the staple food at the bottom of the container and the frozen liquid food as a side meal at the top, and in this case, the staple food and the side meal are brought into contact with each other through a partition wall having holes. We have developed frozen foods in containers that are spaced apart from each other. Further, when the frozen food in the container is heated, the side meal that has been fluidized along with the heating gradually flows down from the pores of the partition wall onto the staple food, so that there is no uneven thawing after the heating, In addition, the present inventors have found that a food in which the staple food and the supplementary food are nicely arranged can be obtained.
したがって、本発明は、容器入り冷凍食品であって、
主食、副食、及びそれらを収納する容器を備え、
該副食は、凍結された流動性食品であり、
該容器の底部に該主食が収納され、該主食部の上部に該副食が収納されており、
該主食と副食は、孔を有する隔壁で互いに接触しないように分離されている、
容器入り冷凍食品を提供する。Therefore, the present invention is a frozen food in a container,
A staple food, a side meal, and a container for storing them,
The side meal is a frozen fluid food;
The staple food is stored at the bottom of the container, and the side food is stored at the top of the staple food part,
The staple food and the side meal are separated so as not to contact each other with a partition wall having holes,
Provide frozen food in containers.
本発明の容器入り冷凍食品によれば、主食と副食を含む複数の食品をまとめて、容器ごと冷凍保存及び加熱することができる。また、本発明の容器入り冷凍食品を加熱すれば、複数の食品を解凍ムラなく加熱することができ、かつ加熱後には、主食と副食とが見栄えよく配置され、そのまま盛り付け作業なしに喫食可能な食品を得ることができる。 According to the container-frozen frozen food of the present invention, a plurality of foods including a staple food and a side meal can be collected together and frozen and stored together with the container. In addition, if the frozen food in a container of the present invention is heated, a plurality of foods can be heated without thawing unevenness, and after heating, the staple food and the side food are arranged nicely and can be eaten without any serving. You can get food.
本発明の容器入り冷凍食品は、容器ごと加熱してそのまま喫食することができる冷凍食品である。本発明の容器入り冷凍食品は、主食及び副食と、それらを収納する容器とを備える。該主食は、該容器の底部に収納される。該副食は、凍結された流動性食品であり、かつ該容器内において該主食の上部に収納されている。本発明の容器入り冷凍食品が冷凍された状態においては、該主食及び副食は、該容器内で、孔を有する隔壁で互いに接触しないように分離されている。本発明の容器入り冷凍食品を、該容器ごと加熱すると、該副食は、加熱による品温上昇に伴って徐々に流動化し、該隔壁の孔から該主食の上に流れ落ちる。該副食が完全に解凍されると、そのほぼ全てが該孔から流れ落ちて、該主食の全部又は少なくとも一部を覆うように容器内に配置される。したがって、本発明の容器入り冷凍食品を加熱すると、該容器内に加熱された主食と副食とが見栄えよく盛り付けられた、１つの料理を作り上げることができる。 The frozen food in a container according to the present invention is a frozen food that can be heated and eaten as it is. The frozen food in a container of the present invention includes a staple food and a side meal, and a container for storing them. The staple food is stored at the bottom of the container. The side meal is a frozen fluid food and is stored in the container above the staple food. In the state where the frozen food in the container of the present invention is frozen, the main food and the side food are separated in the container so as not to contact each other with a partition having a hole. When the frozen food in a container of the present invention is heated together with the container, the side meal gradually fluidizes as the product temperature rises due to heating, and flows down onto the staple food from the holes of the partition walls. When the side meal is completely thawed, almost all of it flows out of the hole and is placed in a container to cover all or at least a portion of the staple food. Therefore, when the frozen food in a container of the present invention is heated, one dish in which the staple food and the side meal heated in the container are nicely arranged can be made up.
本発明の容器入り冷凍食品を喫食する場合は、これを、底部に主食、その上部に副食を収納した状態のまま解凍する。解凍手段は、自然解凍、流水解凍、加温空気や熱風による加熱、電子レンジ加熱等が挙げられるが、電子レンジ加熱が好ましい。本発明の容器入り冷凍食品は、主食と副食が分離して配置されているため、それぞれにマイクロ波がよく行き渡りやすい。また、本発明の容器入り冷凍食品では、加熱に伴う流動化と対流の発生により副食中で熱伝達が促進され、かつ副食が主食上へ流れ落ちることにより主食にも熱が伝達されやすい。したがって、本発明の容器入り冷凍食品を加熱すると、解凍ムラなく全体が効率よく加熱された、品質良好な食品を得ることができる。 When eating the frozen food in a container according to the present invention, this is thawed with the staple food at the bottom and the side food at the top. Examples of the thawing means include natural thawing, flowing water thawing, heating with warm air or hot air, and microwave heating, but microwave heating is preferable. In the frozen food in a container of the present invention, the main food and the side food are separately arranged, so that the microwaves are easily distributed to each of them. Moreover, in the frozen food in a container of the present invention, heat transfer is promoted in the side meal due to fluidization and convection caused by heating, and heat is also easily transmitted to the main meal as the side meal flows down onto the main meal. Therefore, when the frozen food in a container according to the present invention is heated, a food with good quality can be obtained in which the whole is efficiently heated without thawing unevenness.
本発明の容器入り冷凍食品に含まれる主食の好ましい例としては、ご飯、麺、パスタ、イモ類、及びパン、ピザ台等のベーカリー食品などが挙げられる。上記主食は、具材などの固形食品を含んでいてもよい。主食の別な例としては、肉料理、魚介料理、卵料理、野菜料理などの固形食品が挙げられる。あるいは、本発明の容器入り冷凍食品に含まれる主食は、ご飯、麺、パスタ、イモ類、ベーカリー食品などと、上記肉料理、魚料理、卵料理、野菜料理などの固形食品などとの組み合わせであってもよく、その場合、該固形食品は、ご飯、麺、パスタ、イモ類、ベーカリー食品などの上に載置された状態で、容器に収納されていることが好ましい。 Preferable examples of the staple food contained in the frozen food in a container of the present invention include rice, noodles, pasta, potatoes, and bakery foods such as bread and pizza tables. The staple food may contain solid food such as ingredients. Other examples of staple foods include solid foods such as meat dishes, seafood dishes, egg dishes, and vegetable dishes. Alternatively, the staple food contained in the frozen food in the container of the present invention is a combination of rice, noodles, pasta, potatoes, bakery food, etc., and solid foods such as the above meat dishes, fish dishes, egg dishes, vegetable dishes, etc. In that case, the solid food is preferably stored in a container in a state of being placed on rice, noodles, pasta, potatoes, bakery food, or the like.
上記主食は、好ましくは凍結された状態で容器に収納されるが、必ずしもその必要はない。例えば、主食が乾燥春雨、油揚げ麺、クラッカー、ビスケット、コーンフレークのような水分量の少ない食品であれば、そのまま容器に収納し、冷凍保存してもよい。あるいは、冷蔵のご飯、麺、パスタ等を容器に収納し、冷凍保存してもよい。好ましくは、上記主食は、容器内に収納されて冷凍された状態で、０．５〜１５ｃｍ、好ましくは１〜５ｃｍの厚みを有する。厚みが大き過ぎるか又は小さ過ぎると、加熱の際に解凍ムラが生じやすくなる。 The staple food is preferably stored in a container in a frozen state, but it is not always necessary. For example, if the staple food is a food with a low water content such as dry vermicelli, deep-fried noodles, crackers, biscuits, and corn flakes, they may be stored in a container and stored frozen. Alternatively, refrigerated rice, noodles, pasta, etc. may be stored in a container and stored frozen. Preferably, the staple food has a thickness of 0.5 to 15 cm, preferably 1 to 5 cm, when stored in a container and frozen. If the thickness is too large or too small, uneven thawing tends to occur during heating.
本発明の容器入り冷凍食品に含まれる副食は、冷凍温度帯（−５〜−４０℃程度）で固形化しており、喫食温度（４０〜８０℃程度）で流動性を有する流動性食品である。本発明において、副食となる流動性食品は、６０℃において、好ましくは１０〜６００００ｍＰａ・ｓ、より好ましくは５０〜２００００ｍＰａ・ｓ、さらに好ましくは２００〜１００００ｍＰａ・ｓ、なお好ましくは４００〜８０００ｍＰａ・ｓの粘度を有する。副食の粘度が低過ぎると、副食が解凍されないまま主食の上に落下し、加熱後の食品の解凍ムラや、食感や外観の劣化をもたらす場合がある。他方、副食の粘度が高過ぎても、副食の流動が不十分なためにやはり解凍ムラが生じやすくなる。本発明において、副食となる流動性食品の例としては、上記粘度を有するソース、たれ、調味液、ジュレ、ディップなどが挙げられる。該副食は、具材などの固形食品を含んでいてもよい。例えば、具材を含むカレーソースや牛丼のたれなどであってもよい。 The side meal contained in the frozen food contained in the container of the present invention is a fluid food that is solidified in the freezing temperature range (about −5 to −40 ° C.) and has fluidity at the eating temperature (about 40 to 80 ° C.). . In the present invention, the liquid food serving as a side meal is preferably 10 to 60000 mPa · s, more preferably 50 to 20000 mPa · s, still more preferably 200 to 10000 mPa · s, still more preferably 400 to 8000 mPa · s at 60 ° C. Having a viscosity of If the side food is too low in viscosity, the side food may fall onto the main food without being thawed, resulting in uneven thawing of food after heating, and deterioration in texture and appearance. On the other hand, even if the viscosity of the side meal is too high, the flow of the side meal is insufficient, so that thawing unevenness is likely to occur. In the present invention, examples of fluid foods that serve as side dishes include sauces, sauces, seasonings, jelly, dip, and the like having the above viscosity. The side meal may contain solid food such as ingredients. For example, it may be curry sauce containing ingredients or beef bowl sauce.
好ましくは、上記副食は、凍結された状態では、中央部が周辺部に比べて薄い形状を有する。これにより、副食の解凍時間を短縮することができ、かつ解凍ムラがより生じにくくなる。中央部が薄い形状の例としては、上面、下面、又は上下面の中央部に筒型又はドーム型の窪みを有する板若しくは円盤、及びドーナツ形状が挙げられる。好ましくは、副食の中央部の厚さは、最も薄い部分で、副食の周辺部の厚さの７０％以下、より好ましくは５０％以下、さらに好ましくは３０％以下であり、なお好ましくは０％、すなわち副食はドーナツ形状である。また好ましくは、副食の中央部とは、副食の上面又は下面の中央部における、該上面又は下面の面積の２０〜８０％、より好ましくは３０〜６０％程度を占める領域である。 Preferably, in the frozen state, the side meal has a shape that is thinner at the center than at the periphery. As a result, the thawing time of the side meal can be shortened and thawing unevenness is less likely to occur. Examples of the shape having a thin central portion include a plate or a disk having a cylindrical or dome-shaped depression in the central portion of the upper surface, the lower surface, or the upper and lower surfaces, and a donut shape. Preferably, the thickness of the central part of the side meal is the thinnest part, and is 70% or less, more preferably 50% or less, further preferably 30% or less, more preferably 0% of the thickness of the peripheral part of the side meal. That is, the side meal has a donut shape. Preferably, the central portion of the side meal is a region that occupies 20 to 80%, more preferably about 30 to 60%, of the area of the upper surface or the lower surface in the central portion of the upper surface or the lower surface of the supplement.
好ましくは、上記副食は、凍結された状態で、少なくとも周辺部が、０．５〜８ｃｍの厚みを有する。当該厚さが０．５ｃｍ未満の場合、解凍されても表面張力の作用で隔壁の孔から下に流れ落ちにくくなる。他方、当該厚さが８ｃｍを超えると、解凍ムラが生じやすくなる。 Preferably, the side meal has a thickness of 0.5 to 8 cm in a frozen state. When the thickness is less than 0.5 cm, even if it is thawed, it becomes difficult to flow down from the hole of the partition wall due to the effect of surface tension. On the other hand, if the thickness exceeds 8 cm, thawing unevenness tends to occur.
本発明の容器入り冷凍食品に含まれる主食と副食とは、それらを組み合わせたときに１つの料理を構成できるものであることが好ましい。組み合わせによって得られる料理の具体例としては、牛丼、中華丼、カレーライス、ハヤシライスなどの飯もの、カレーうどん、あんかけ焼きそばなどの麺もの、ソース付パスタやピザ、ソースをかけた肉、魚介又は卵の料理、カツカレーやロコモコ等の飯と肉料理の組み合わせ、などが挙げられる。したがって、主食と副食の組み合わせの好ましい例としては、ご飯とカレーソース、ハヤシライスソース又はトマトソースなどのソース、ご飯とたれ、うどんや中華麺等の麺とつゆ又はソース、パスタとパスタソース、ピザとピザソース、ハンバーグとそのソースなどが挙げられるが、これらに限定されるものではなく、消費者の嗜好に応じて任意の組み合わせが可能である。 It is preferable that the main food and the side food contained in the frozen food in a container of the present invention can constitute one dish when they are combined. Specific examples of dishes obtained by the combination include rice dishes such as beef bowl, Chinese rice bowl, curry rice, hayashi rice, noodle dishes such as curry udon, ankake yakisoba, pasta and pizza with sauce, meat with sauce, seafood or Egg dishes, a combination of rice and meat dishes such as cutlet curry and loco moco. Therefore, preferable examples of combinations of staple foods and side meals include rice and curry sauces, sauces such as hayashi rice sauce or tomato sauce, rice and sauce, noodles and soy sauce such as udon and Chinese noodles, pasta and pasta sauce, pizza and Examples include pizza sauce, hamburger and its sauce, but are not limited thereto, and any combination is possible according to consumer preference.
本発明の容器入り冷凍食品において、上記主食と副食とを収納する容器は、該主食と副食の冷凍保存及び加熱のための容器として、ならびに加熱された主食と副食のための食器として用いられる。該容器は、底壁と周壁とを備え、上部が開口した容器であればよく、その形状や大きさは、隔壁を介して主食と副食とを収納することができ、かつ加熱の際に収納した主食と副食が容器からこぼれたり溢れたりしない限り、特に限定されない。例えば、容器の形状としては、丸型又は角型のカップ、ボウル、深皿などが挙げられる。さらに、保温性や耐衝撃性向上のために該容器を２重底にしたり、安定性向上のため該容器の底に脚部を設けたりしてもよい。 In the frozen food contained in the container of the present invention, the container for storing the staple food and the side meal is used as a container for storing and heating the staple food and the side meal, and as a tableware for the heated staple food and the side meal. The container only needs to be a container having a bottom wall and a peripheral wall and having an open top. The shape and size of the container can store the staple food and the supplementary food via the partition wall, and can be stored when heated. There is no particular limitation as long as the staple foods and side dishes do not spill or overflow from the container. For example, examples of the shape of the container include a round or square cup, bowl, and deep dish. Furthermore, the container may be double-bottomed for improving heat retention and impact resistance, or legs may be provided on the bottom of the container for improving stability.
上記容器内には、底部に主食が収納され、その上部に凍結された副食が収納されている。ただし、該主食と副食の間には、孔を有する隔壁が設けられている。したがって、該主食と副食は、該隔壁により分離されて配置されており、冷凍保存状態では互いに接触していない。容器内で主食と副食が接触しないように配置することにより、冷凍保存中及び加熱中における主食と副食との間の水分移動が防止されるため、加熱後の食品の品質（外観、食感など）を向上させることができる。一方、隔壁が孔を有することにより、加熱されて流動化した副食は、該孔を通って主食の上に流れ落ちることができるので、本発明の容器入り冷凍食品を加熱するだけで、主食の上に副食が盛り付けられた１つの料理ができあがる。 In the container, staple food is stored at the bottom, and frozen side dishes are stored at the top. However, a partition wall having a hole is provided between the staple food and the side meal. Therefore, the staple food and the supplementary food are arranged separated by the partition walls and are not in contact with each other in the frozen storage state. By arranging the main food and side food so that they do not come into contact with each other in the container, water movement between the main food and side food during frozen storage and heating is prevented, so the quality of the food after heating (appearance, texture, etc.) ) Can be improved. On the other hand, because the partition walls have holes, the heated and fluidized side meal can flow down onto the staple food through the holes. A dish with a side dish is completed.
好ましくは、上記隔壁は、未解凍の副食と主食との接触を妨げる一方で、加熱されて流動化した副食が該孔以外の部分から主食の上に流れ落ちることを防止することができる形状及び大きさを有する。例えば、上記孔を有する隔壁は、周縁又は周壁を有する皿状、中央に向かって深くなる皿状、ボウル状などの中皿の形状であり得、該中皿の底面が、前記孔を有する隔壁を構成する。また例えば、上記隔壁又は中皿は、全周が容器の内側壁と接触する大きさであってもよく、又はその周囲の一部が容器の内側壁と接触する大きさであってもよい。必要に応じて、該孔から副食が流れ落ちやすくするように、上記隔壁の面は、該孔に向かって傾斜していたり、凹凸を有していてもよい。 Preferably, the partition wall has a shape and a size capable of preventing contact between the unthawed side meal and the main meal while preventing the heated and fluidized side meal from flowing down from the portion other than the holes onto the main meal. Have For example, the partition having the hole may be in the shape of a dish such as a dish having a peripheral edge or a peripheral wall, a dish having a depth toward the center, or a bowl, and the bottom of the dish has the hole having the hole. Configure. Further, for example, the partition wall or the inner dish may be sized so that the entire circumference is in contact with the inner side wall of the container, or may be sized so that a part of the periphery thereof is in contact with the inner side wall of the container. If necessary, the surface of the partition wall may be inclined toward the hole or may have irregularities so that the side food easily flows down from the hole.
上記容器を加熱後に食器として使用する際の利便性を考慮すると、上記隔壁は該容器から取り外し可能であって、本発明の容器入り冷凍食品を加熱した後には除去されることが好ましい。 In consideration of convenience when using the container as tableware after heating, the partition wall is preferably removable from the container, and is preferably removed after heating the frozen food in the container of the present invention.
上記隔壁の孔の形や大きさは、副食の流動性や、副食に含まれる食材の大きさによっても異なるが、円形又は多角形上の孔が好ましい。また、孔の総面積は、好ましくは１０ｃｍ2以上、より好ましくは１５ｃｍ2以上、さらに好ましくは２５ｃｍ2以上であって、かつ好ましくは１５０ｃｍ2以下、より好ましくは１２０ｃｍ2以下、さらに好ましくは１００ｃｍ2以下である。さらにより好ましくは、孔の総面積は２５〜１００ｃｍ2、なお好ましくは３０〜７０ｃｍ2である。孔の総面積が１０ｃｍ2未満であると、副食の流れ落ちが遅くなって副食が過加熱となることがある。他方、孔の総面積が１２０ｃｍ2を超えると、副食が十分に解凍されないまま主食の上に落下することにより、解凍ムラが起こることがある。あるいは、孔の総面積は、上記隔壁の総面積（孔の面積を含む）に対して、好ましくは５〜９５％程度、より好ましくは９〜８６％程度、さらに好ましくは１４〜６０％程度、なお好ましくは１７〜４０％程度、なお好ましくは２５〜４０％程度である。The shape and size of the pores in the partition walls vary depending on the flowability of the side food and the size of the food contained in the side food, but circular or polygonal holes are preferable. Further, the total area of the holes is preferably 10 cm 2 or more, more preferably 15 cm 2 or more, further preferably 25 cm 2 or more, and preferably 150 cm 2 or less, more preferably 120 cm 2 or less, still more preferably 100 cm 2. It is as follows. Even more preferably, the total area of the holes is 25-100 cm 2 , still more preferably 30-70 cm 2 . If the total area of the holes is less than 10 cm 2 , the side meal may slow down and the side meal may be overheated. On the other hand, if the total area of the holes exceeds 120 cm 2 , thawing unevenness may occur due to the side food falling onto the main food without being sufficiently thawed. Alternatively, the total area of the holes is preferably about 5 to 95%, more preferably about 9 to 86%, and still more preferably about 14 to 60% with respect to the total area of the partition wall (including the area of the holes). Preferably, it is about 17-40%, more preferably about 25-40%.
上記隔壁の孔の数は、複数であってもよいが、４個以下が好ましく、１つがより好ましい。孔の数が増えると、各孔の面積が小さくなり、その結果上述した副食の過加熱の問題が生じやすくなる。さらに、副食の加熱ムラを防ぐ観点からは、孔は隔壁の中央部にあることが好ましい。より好ましくは、該隔壁は、中央部に１つの孔を有する。 Although the number of holes in the partition may be plural, it is preferably 4 or less, and more preferably 1. As the number of holes increases, the area of each hole decreases, and as a result, the above-described problem of overheating of side dishes tends to occur. Furthermore, from the viewpoint of preventing uneven heating of the side meal, the hole is preferably in the center of the partition wall. More preferably, the partition has one hole in the center.
好ましくは、上記容器内において、上記凍結された副食は、上記孔を有する隔壁上に載置されている。例えば、該容器は、主食の上部に配置された、底面に孔を有する中皿を備え、凍結された副食は、該中皿に載置されており、該中皿の底面は、該主食と副食とを分離する隔壁を構成する。 Preferably, in the container, the frozen side meal is placed on a partition having the hole. For example, the container includes a middle dish disposed on the top of the staple food and having a hole on the bottom surface, and the frozen side dish is placed on the middle dish, and the bottom surface of the middle dish is separated from the staple food. The partition which separates a side meal is comprised.
一方で、上記容器内の主食は、加熱の際に該隔壁の孔から副食が流れ落ちることを妨げないように、該隔壁から離して配置されることが好ましい。好ましくは、該容器内の主食と副食は、冷凍保存状態では、それらの間に０．１ｍｍ〜５ｃｍの間隙をあけて配置されている。 On the other hand, it is preferable that the staple food in the container is arranged away from the partition so as not to prevent the side food from flowing down from the hole of the partition during heating. Preferably, the main meal and the side meal in the container are arranged with a gap of 0.1 mm to 5 cm between them in the frozen storage state.
したがって、上記隔壁は、上記容器の上縁部、又は内壁上の突起や段差部などにより支持されていることが好ましい。これらの支持により、該容器内部で隔壁と主食とを分離することができ、また加熱中に流動化した副食の重みによる該隔壁の変形や傾きを防止することができる。例えば、上記容器は、その周壁の内側に複数の突起を備えているか、該周壁の内側の一部に設けられた段差部を備えているか、又は該周壁の内側を一周する段差部を備えており、これらの突起又は段差部により該隔壁は支持される。また例えば、該隔壁は、１つ以上のフック又は周囲にフランジを備え、該フック又はフランジを容器の上縁部に掛けることで、該隔壁が支持される。 Therefore, it is preferable that the partition wall is supported by an upper edge portion of the container or a protrusion or a step portion on the inner wall. With these supports, the partition walls and the staple food can be separated inside the container, and deformation and inclination of the partition walls due to the weight of the side food fluidized during heating can be prevented. For example, the container includes a plurality of protrusions on the inner side of the peripheral wall, a step portion provided on a part of the inner side of the peripheral wall, or a step portion that goes around the inner side of the peripheral wall. The partition walls are supported by these protrusions or stepped portions. Further, for example, the partition wall is provided with one or more hooks or a flange around the hook, and the partition wall is supported by hanging the hook or flange on the upper edge of the container.
