Description
【０００１】[0001]
本考案は、例えば、カレーと米飯等、マイクロ波の照射による加熱特性が異な る二種以上の食品を同一容器内にて同時間に殺菌及び調理することが可能なマイ クロ波透過性容器に関する。 The present invention relates to a microwave permeable container capable of simultaneously sterilizing and cooking two or more kinds of foods, such as curry and cooked rice, which have different heating characteristics by microwave irradiation in the same container at the same time. .
【０００２】[0002]
従来、マイクロ波の照射によって再加熱調理が可能である食品のうち、例えば 、カレーライス等の食品においては、生産者側でカレーと米飯を別々のトレーや パウチ等の容器に収納し、別々にマイクロ波を照射して殺菌及び加熱処理し、そ の後、個々のトレー等を組み合せて包装販売していた。 Conventionally, among foods that can be reheated and cooked by microwave irradiation, for example, for foods such as curry rice, the producer stores curry and cooked rice in separate trays or pouches, and separates them. It was irradiated with microwaves for sterilization and heat treatment, and then individual trays were combined and packaged and sold.
【０００３】 一方、消費者側では、この個々の容器に収納された食品を別々に家庭用電子レ ンジにて再加熱調理し、その後、カレーと米飯を一緒（混合）にして食するか、 或いは、一方の容器内に他方の容器に収納された内容物を移し替え、その状態に て、食する直前に家庭内における電子レンジで再加熱調理すれば出来上がるよう にしていた（特開平１−２９６９４９号公報参照）。On the other hand, on the consumer side, the foods stored in the individual containers are separately reheated and cooked in a home electronic range, and then curry and cooked rice are mixed (mixed) together for eating. Alternatively, the contents stored in the other container may be transferred into one container, and in that state, the food may be reheated and cooked in a microwave oven at home immediately before eating (JP-A-1- 296949).
【０００４】 また、前記食品においては、予め生産者側が一つの容器内で、前記米飯にカレ ーを乗せた状態にて冷凍収納し、消費者側において、そのまま電子レンジで解凍 調理させるもの（特開昭６３−１０９７４８号公報参照）なども案出されている 。[0004] In addition, in the above food, the producer preliminarily stores the food in a container in a state that the cooked rice is put on a curry, and the consumer directly defrosts and cooks it in a microwave oven (special feature). For example, see Japanese Patent Laid-Open No. 63-109748).
【０００５】 ところが、前記特開平１−２９６９４９号や特開昭６３−１０９７４８号など の場合、生産者側の収納，殺菌，包装工程においても、また、消費者側の再加熱 調理工程においてもかなりの時間（単純に食品の種類に比例する時間）及びコス トを要し、大変作業能率が悪く、また、不経済であった。However, in the case of JP-A-1-296949 and JP-A-63-109748, the storage, sterilization and packaging processes on the producer side and the reheating and cooking process on the consumer side are considerably difficult. It took a lot of time (simply proportional to the type of food) and cost, resulting in very poor work efficiency and was uneconomical.
【０００６】 更に、カレーと米飯との混ざり具合が好みに適さなかったり、カレーと米飯間 で加熱ムラが生じて食する最適温度にならなかったりする上、出来上がり状態も カレーが米飯に混合してしまい見掛け上も良くない。[0006] Furthermore, the mixture of curry and cooked rice is not suitable for taste, heating unevenness occurs between the curry and cooked rice, and the optimum temperature for eating is not achieved. It looks bad, too.
【０００７】 そこで、大トレーに別途、或いは一体的に仕切りを設け、一方にカレー等を、 他方に米飯等をそれぞれ収納し、同一容器にて同時間に殺菌及び調理できる容器 が案出された（特開平２−１５４６５１号公報参照）。Therefore, a container has been devised in which a large tray is provided with a partition separately or integrally, curry or the like is stored in one side and cooked rice or the like is stored in the other side, and the same container can sterilize and cook at the same time. (See Japanese Patent Laid-Open No. 2-154651).
【０００８】[0008]
ところが、前記トレーに仕切りを設けた一つの容器を使用し、それぞれの食品 を仕切り毎に収納し、同時にマイクロ波を照射して殺菌及び加熱処理を行うと、 前記二種の食品（カレーと米飯等）の加熱昇温状態が異なる（例えば、米飯は水 分が少ないので速く、カレーはその内部に存在する土壌菌を殺菌するのに時間が かかると共に塩分が多いので遅い。）ので、双方に加熱ムラが生じ、何れにしろ 、うまく調理することができないでいた。 However, when using one container with a partition on the tray, each food is stored for each partition, and at the same time microwave irradiation is performed for sterilization and heat treatment, the two types of food (curry and cooked rice) are Etc.) (for example, cooked rice has a low water content, so it is fast, and curry takes a long time to sterilize the soil bacteria present inside it, and it has a high salt content, so it is slow). Irregularity of heating occurred, and in any case, it was not possible to cook well.
【０００９】 そこで、本考案では、同一容器内に収納したマイクロ波の照射による加熱特性 が異なる二種以上の食品を、同時間に常時ムラなく、効率よく殺菌すると共に、 加熱調理することが可能なマイクロ波透過性容器を提供することを課題とする。Therefore, according to the present invention, it is possible to sterilize two or more kinds of foods, which are stored in the same container and have different heating characteristics due to the irradiation of microwaves, at the same time without any unevenness, and to heat and cook them. An object of the present invention is to provide a microwave transparent container.

本考案は、上記課題を解決するために次の第一〜第五の技術的手段を講じる。 The present invention takes the following first to fifth technical means in order to solve the above problems.
【００１１】 前記第一手段は、マイクロ波透過性を有し、且つ二種以上の食品を収納して殺 菌すると共に、加熱調理する容器において、容器本体1 が、連結部6 を介して一 体的に連結された複数個の収納体7a,7b …からなり、該各収納体7a,7b …間には 空間部5 が設けられ、且つ前記収納体の少なくとも一つの底部4aが、対抗する他 の収納体に向かって浅くなるように傾斜されてなることを特徴とするものである 。The first means is a container that has microwave permeability and stores two or more kinds of foods to sterilize them, and heats and cooks the container main body 1 via the connecting portion 6. It is composed of a plurality of storage bodies 7a, 7b ... Physically connected to each other, a space 5 is provided between the storage bodies 7a, 7b ... And at least one bottom portion 4a of the storage bodies opposes each other. It is characterized in that it is inclined so that it becomes shallower toward other containers.
【００１２】 前記第二手段は、マイクロ波透過性を有し、且つ二種以上の食品を収納して殺 菌すると共に、加熱調理する容器において、容器本体1 が、連結部6 を介して一 体的に連結された複数個の収納体7a,7b …からなり、該各収納体7a,7b …間には 空間部5 が設けられ、且つ前記収納体の少なくとも一つの底部4bが、該収納体の 略中央部10に向かって浅くなるように曲面凸状に形成されてなることを特徴とす るものである。The second means is a container that has microwave permeability and stores two or more kinds of foods to sterilize them, and heats and cooks them. It is composed of a plurality of storage bodies 7a, 7b ... Which are physically connected, a space 5 is provided between the storage bodies 7a, 7b ... And at least one bottom 4b of the storage bodies is It is characterized in that it is formed in a curved convex shape so as to become shallower toward the substantially central portion 10 of the body.

【００１５】 前記第五手段は、前記容器本体1 が、エチレン−ビニルアルコール共重合樹脂 を有する多層積層体にて構成されていることである。The fifth means is that the container body 1 is composed of a multilayer laminate having an ethylene-vinyl alcohol copolymer resin.
【００１６】[0016]
本考案に係るマイクロ波透過性容器は、連結部6 を介して一体的に連結された 複数個の収納体7a,7b …からなり、該各収納体7a,7b …間には空間部5 が設けら れているので、通常マイクロ波の影響を受けにくい容器本体中央部であっても、 前記空間部5 にて、食品に対するマイクロ波の熱伝導性がよくなり、加熱速度が 速くなる。 The microwave permeable container according to the present invention comprises a plurality of storage bodies 7a, 7b ... Which are integrally connected via a connecting portion 6, and a space 5 is provided between the storage bodies 7a, 7b. Since it is provided, even in the central portion of the container main body, which is generally not easily affected by microwaves, the thermal conductivity of microwaves to food is improved in the space portion 5, and the heating speed is increased.
【００１７】 また、本考案に係るマイクロ波透過性容器の区画された収納体の少なくとも一 つの底部4aが、内側に向かって浅くなるように傾斜されていたり、少なくとも一 つの底部4bが、該収納体の略中央部10に向かって浅くなるように曲面凸状に形成 されているので、食品の誘電特性に適宜対応させて、加熱速度が遅い食品を、速 い食品に対して、浅い部分を多く有する収納体側に収納するという簡単な工程に て、個々の収納体内での加熱ムラを生じることがない上、各収納体間においても 、その加熱状態に差を生じず、双方でムラなく加熱調理が可能である。Further, at least one bottom part 4a of the compartmented container of the microwave permeable container according to the present invention is inclined so as to become shallower toward the inner side, or at least one bottom part 4b is accommodated. Since it is formed in a curved convex shape so that it becomes shallower toward the approximate center 10 of the body, foods with slow heating speeds and shallow parts with respect to fast foods can be made to correspond to the dielectric properties of foods as appropriate. In the simple process of storing in many containers, there is no uneven heating in each container, and there is no difference in the heating state between each container, so that both can be heated evenly. Can be cooked.
【００１８】 従って、たとえマイクロ波の照射による加熱特性が異なる食品を各収納体へ収 納したとしても、同時間にて、全体的に均一の殺菌処理及び加熱処理が可能であ る。Therefore, even if foods having different heating characteristics due to microwave irradiation are stored in the respective storage bodies, it is possible to perform uniform and uniform sterilization treatment and heat treatment at the same time.
【００１９】 更に、本考案に係るマイクロ波透過性容器で、各収納体7a,7b …の底部4a,4b …の周縁部8,9,11,12 …が曲面状に設けられているものにおいては、圧力変動に 対して、耐圧力変形性を有するので、非常に安定性のある容器となる上、昇温個 所が分散することになるので、個々の収納体内の食品においても加熱ムラが少な く、加熱速度も速くなる。Further, in the microwave permeable container according to the present invention, in which the peripheral portions 8, 9, 11, 12, ... Of the bottom portions 4a, 4b of each of the storage bodies 7a, 7b. Since it has a pressure deformation resistance against pressure fluctuations, it becomes a very stable container, and since the temperature rising points are dispersed, heating unevenness is also observed in the food in each container. The heating rate will be faster.
【００２０】 また、本考案に係るマイクロ波透過性容器にエチレン−ビニルアルコール共重 合樹脂からなる多層積層体を使用するものにおいては、前記エチレン−ビニルア ルコール共重合樹脂の有するガスバリヤー特性や耐熱性にて、マイクロ波透過に 特に適した容器となると共に、廃棄処理の面やコストの面からも好ましいものと なる。Further, in the microwave permeable container according to the present invention in which a multilayer laminate made of ethylene-vinyl alcohol copolymer resin is used, the gas barrier property and heat resistance of the ethylene-vinyl alcohol copolymer resin are In terms of properties, it becomes a container that is particularly suitable for microwave transmission, and is also preferable from the viewpoint of disposal and cost.
【００２１】[0021]
以下、本考案の一実施例として，カレーライスのカレーと米飯とを、別々に一 つの容器内に収納し、殺菌及び加熱することが可能なマイクロ波透過性容器につ いて図面に基づき説明する。 As an embodiment of the present invention, a microwave permeable container in which curry and rice curry and cooked rice are separately stored in one container, and which can be sterilized and heated will be described with reference to the drawings. .
【００２２】 一般に、マイクロ波の照射による加熱は、誘導体となる食品の誘電特性（マイ クロ波電界によって振動する分子間の摩擦熱に基づくもので、下記式１にて示さ れる。）によって様々の昇温状態を有し、例えば、前記米飯はεtan δ（損失係 数）が１０，カレーは該εtan δが２０程度である。In general, heating by microwave irradiation varies depending on the dielectric properties of the food serving as a derivative (based on frictional heat between molecules vibrating by a microwave electric field and represented by the following formula 1). It has a temperature rising state. For example, the cooked rice has an ε tan δ (loss coefficient) of 10, and the curry has an ε tan δ of about 20.
【００２３】[0023]
【式１】 Ｐ＝εtan δ 尚、 ε＝誘電率 tan δ＝誘電正接 δ＝誘電体損失角 である。## EQU1 ## P = ε tan δ where ε = dielectric constant tan δ = dielectric loss tangent δ = dielectric loss angle.
【００２４】 前記のように食品によって誘電特性が異なる要因としては水分や塩分等が挙げ られるが、前記米飯は水分や塩分が少ないため、マイクロ波の吸収量は多いが、 容器中央部の昇温速度が遅い。As described above, factors such as differences in dielectric properties depending on foods include water and salt. However, since the cooked rice has a small amount of water and salt, the microwave absorption is large, but the temperature rise in the center of the container The speed is slow.
【００２５】 また、前記カレーは塩分が多く含有され、その内在物としてジャガイモや肉等 が入っていることも相俟って、損失係数が大きく、マイクロ波の浸透深度が浅く て、容器周縁部と中央部の昇温速度が著しく異なる上、前記内在物に存在する土 壌菌を殺菌するのにかなりの時間を要するので、全体的な加熱速度も遅い。In addition, the curry contains a large amount of salt and contains potatoes, meat, etc. as its internal components, which results in a large loss coefficient, a small penetration depth of microwaves, and a peripheral portion of the container. In addition, the heating rate of the central part is significantly different, and since it takes a considerable time to sterilize the soil bacteria existing in the above-mentioned internal substances, the overall heating rate is also slow.
【００２６】 本考案では、このように誘電特性の異なる２つのカレーと米飯とを同一容器内 にて同時間に殺菌及び調理することが可能な容器を提供することが目的であり、 以下に本実施例のマイクロ波透過性容器について詳述する。An object of the present invention is to provide a container capable of simultaneously sterilizing and cooking two curries having different dielectric properties and cooked rice in the same container as described below. The microwave transparent container of the example will be described in detail.
【００２７】 本実施例のマイクロ波透過性容器は、図１〜図４で示すように、マイクロ波透 過性を有するプラスチック製の容器であって、円形状の輪郭を有する開口部2 と 側壁部3 及び底部4 とを備えた容器本体1 からなり、加熱特性（詳しくは誘電特 性）が異なるカレーと米飯を別々に収納できるように、下部に空間部5 を有する 連結部6 によって、２個の収納体7a,7b に区画されている。As shown in FIGS. 1 to 4, the microwave permeable container of the present embodiment is a microwave permeable plastic container having an opening 2 having a circular contour and a side wall. It consists of a container body 1 with a part 3 and a bottom part 4, and has a space 6 at the bottom so that curry and cooked rice with different heating characteristics (more specifically, dielectric properties) can be stored separately. It is divided into individual storage bodies 7a and 7b.
【００２８】 前記一方の収納体7a（図１及び図２では右側に示す収納体とする。）は、損失 係数が大きいカレーを収納するために、その底部4aが、他方の収納体7b（図１及 び図２では左側に示す収納体とする。）に向かって山型に浅くなるよう傾斜され て、該底部4aの外周縁部8 と内周縁部9 との高さの差（ｈ1 ）が約13mmとなるよ うに盛り上げられ、且つ前記外周縁部8 及び内周縁部9 が曲率半径，Ｒ≧１５mm に設けられている。One of the storage bodies 7a (the storage body shown on the right side in FIGS. 1 and 2) has a bottom portion 4a for storing the curry having a large loss coefficient, and the other storage body 7b (see FIGS. 1 and the housing shown on the left in FIG. 2), the height difference between the outer peripheral edge portion 8 and the inner peripheral edge portion 9 of the bottom portion 4a (h 1 ) Is about 13 mm, and the outer peripheral edge portion 8 and the inner peripheral edge portion 9 are provided with a radius of curvature, R ≧ 15 mm.
【００２９】 また、他方の収納体7bは、損失係数が小さく、中央部の昇温速度が遅い米飯を 収納するために、その底部4bの略中央部10に向かって浅くなるように曲面凸状に 盛り上げられ（ｈ2=約６mm）、且つ前記底部4bの外周縁部11及び内周縁部12が曲 率半径，Ｒ≧１５mmに設けられている。The other container 7b has a curved convex shape so as to become shallower toward the substantially central portion 10 of the bottom portion 4b thereof in order to accommodate cooked rice having a small loss coefficient and a slow temperature rising rate in the central portion. (H 2 = about 6 mm), and the outer peripheral edge portion 11 and the inner peripheral edge portion 12 of the bottom portion 4 b are provided with a curvature radius R ≧ 15 mm.
【００３０】 前記のように構成された本実施例のマイクロ波透過性容器を使用して、生産者 側では、前記収納体7aにカレーを，収納体7bに米飯をそれぞれ収納し、該容器本 体1 の開口部2 を耐熱性を有するプラスチック製の蓋（図示省略）でヒートシー ル等の公知の手段にて密封し、マイクロ波加熱装置内に配置し、次いで、所定の 加圧条件下にてマイクロ波を照射することで、米飯とカレーの殺菌及び加熱処理 時間を同じにして、工場レベルにおける該食品（カレーライス）の殺菌処理を施 すことができると共に、加熱調理を施すことが可能である。Using the microwave permeable container of the present embodiment configured as described above, the producer stores curry in the container 7a and cooked rice in the container 7b. The opening 2 of the body 1 is sealed with a heat-resistant plastic lid (not shown) by a known means such as a heat seal, placed in a microwave heating device, and then placed under predetermined pressurizing conditions. By irradiating microwave with microwave, it is possible to sterilize cooked rice and curry and heat treatment at the same time, and to sterilize the food (curry rice) at the factory level and heat it Is.
【００３１】 この際、前記容器本体1 の中央部に空間部5 が設けられているので、該空間部 5 内を障害なくマイクロ波が通過し、また、各収納体7a,7b の内部側壁部13から もマイクロ波の透過が可能となるので、効率よくマイクロ波の照射が行え、加熱 ムラを充分解消できる。At this time, since the space 5 is provided in the central portion of the container body 1, microwaves pass through the space 5 without obstruction, and the inner side wall of each of the storage bodies 7a, 7b. Since microwaves can be transmitted from 13 as well, microwaves can be efficiently radiated and uneven heating can be sufficiently eliminated.
【００３２】 また、家庭内においても、前記容器に収納されたままのカレーライスを電子レ ンジにて再加熱調理するだけで、たとえ、誘電特性の異なるカレーと米飯であっ ても、前記同様出来上がり時間や状態において双方が均一な出来具合を有するも のとなる。Further, even at home, the curry rice just stored in the container is simply reheated and cooked by an electronic range, and even if curry and cooked rice having different dielectric properties are cooked, the result is similar to the above. Both will have a uniform quality over time and conditions.
【００３３】 更に、前記底部4 の外周縁部8,11や内周縁部9,12を曲面状に設けることで、マ イクロ波が局所的に集中照射されることがないので、昇温個所が分散し、個々の 食品においてもその収納体内で加熱ムラ等を生じることがない。Furthermore, since the outer peripheral edge portions 8 and 11 and the inner peripheral edge portions 9 and 12 of the bottom portion 4 are provided in a curved shape, the microwaves are not locally focused and irradiated, so that the temperature rise location is Disperses and does not cause uneven heating even in individual food items.
【００３４】 前記容器本体1 を構成する素材としては、マイクロ波透過性を有するものであ れば、どの様なものでも良いが、例えば、エチレンモノマー単位１０〜５０モル ％含有のエチレン−ビニルアルコール共重合樹脂（以下、ＥＶＯＨと記す。）や 、該ＥＶＯＨを基体とする変性物よりなるシート基材の表裏両面にポリエチレン 、ポリプロピレン、、ポリエチレンテレフタレート、エチレン・α−オレフィン 共重合体などの疏水性樹脂、或いはポリアミド系の親水性樹脂よりなるカバーシ ートが積層挟着されて、ＥＶＯＨそのものが直接表面に出ないように複合された 多層積層体等であれば、前記ＥＶＯＨの有するガスバリヤー特性や耐熱性にて、 マイクロ波照射による加熱処理に特に適した容器となると共に、廃棄処理の面や コストの面からも好ましい容器となり得る。Any material may be used as a material forming the container body 1 as long as it has microwave permeability. For example, ethylene-vinyl alcohol containing 10 to 50 mol% of ethylene monomer units is used. Hydrophobicity of polyethylene, polypropylene, polyethylene terephthalate, ethylene / α-olefin copolymers, etc. In the case of a multilayer laminate in which cover sheets made of a resin or a polyamide-based hydrophilic resin are laminated and sandwiched so that EVOH itself does not directly appear on the surface, a gas barrier property of the EVOH or Due to its heat resistance, it becomes a container that is particularly suitable for heat treatment by microwave irradiation, It may be a preferred container in terms of bets.
【００３５】 また、前記容器本体1 の底部4 の外周縁部8,11が面一に設けられているので、 容器自体の安定性が充分にあり、非常に食べやすいものとなる。Further, since the outer peripheral edge portions 8 and 11 of the bottom portion 4 of the container body 1 are provided flush with each other, the container itself has sufficient stability and becomes very easy to eat.
【００３６】 尚、本実施例では特に、カレーライスの収納容器を例に挙げて説明したが、そ の他、スパゲティにおけるスパゲティソースと麺や、丼物における米飯と具等最 終的に混合して食する食品は勿論、御飯とおかず等、もともと別々に食するもの においても使用可能である。In the present embodiment, the curry and rice storage container has been described as an example. However, in addition to this, spaghetti sauce and noodles in spaghetti and cooked rice and ingredients in a bowl are finally mixed. It can be used not only for foods that are eaten by eating, but also for foods that are originally eaten separately, such as rice and side dishes.
【００３７】 更に、本実施例では２種の食品を収納する容器を例に挙げて説明したが、例え ば、図５や図６に示すように３個の収納体7a,7b,7c、若しくはそれ以上の収納体 を設けることで、より多種類の食品を同時に最適状態にて殺菌処理及び加熱調理 することが可能となる。Further, although the present embodiment has been described by taking the container for storing two kinds of foods as an example, for example, as shown in FIG. 5 and FIG. 6, three containers 7a, 7b, 7c, or By providing more storages, more kinds of foods can be sterilized and cooked in the optimum condition at the same time.
【００３８】 前記のように食品の種類によって（損失係数の差によって）、底部4aの外周縁 部8 と内周縁部9 との高さの差（ｈ1 ）、曲面凸状の高さ（ｈ2 ）、及び曲率半 径（Ｒ）等を適宜変更し、また収納体の選択を行うことで、どのような食品にお いても本考案のマイクロ波透過性容器を使用することが可能である。As described above, depending on the type of food (due to the difference in loss coefficient), the height difference (h 1 ) between the outer peripheral edge portion 8 and the inner peripheral edge portion 9 of the bottom portion 4 a, the height of the curved surface convex portion (h 2 ), the radius of curvature (R), etc. are appropriately changed, and the container is selected so that the microwave permeable container of the present invention can be used in any food. .
【００３９】[0039]
本考案のマイクロ波透過性容器は、連結部を介して一体的に連結された複数個 の収納体からなり、該各収納体間には空間部が設けられているので、通常マイク ロ波の影響を受けにくい容器本体中央部であっても、前記空間部にて、食品に対 するマイクロ波の熱伝導性がよくなり、加熱速度が速くなる。 The microwave permeable container of the present invention is composed of a plurality of containers integrally connected through a connector, and a space is provided between the containers, so that the microwave permeable container is Even in the central portion of the container body which is not easily affected, the thermal conductivity of microwaves with respect to food is improved in the space portion, and the heating rate is increased.
【００４０】 また、本考案に係るマイクロ波透過性容器の区画された収納体の少なくとも一 つの底部が、内側に向かって浅くなるように傾斜されていたり、少なくとも一つ の底部が、該収納体の略中央部に向かって浅くなるように曲面凸状に形成されて いるので、食品の誘電特性の適宜対応させて、加熱速度が遅い食品を、速い食品 に対して、浅い部分を多く有する収納体側に収納すれば、個々の収納体内での加 熱ムラを生じることがない上、各収納体間においても加熱状態に差を生じないの で、たとえマイクロ波の照射による加熱特性が異なる食品を各収納体へ収納した としても、同時間にて、容器全体的に均一の殺菌処理及び加熱処理を施すことが できる。Further, at least one bottom of the compartmented container of the microwave permeable container according to the present invention is inclined so as to become shallower toward the inside, or at least one bottom of the container is formed. Since it is formed in a curved convex shape so that it becomes shallower toward the approximate center, the food with slow heating speed and the food with many shallow parts are accommodated according to the dielectric characteristics of the food. When stored on the body side, heating unevenness in each storage body does not occur and there is no difference in the heating state between storage bodies, so even if foods with different heating characteristics due to microwave irradiation are used. Even when stored in each container, uniform sterilization and heat treatment can be performed on the entire container at the same time.
【００４１】 更に、各収納体の底部の周縁部を曲面状に設けた場合は、圧力変動に対して、 耐圧力変形性を有するので、非常に安定性のある容器となる上、昇温個所が分散 することになるので、加熱ムラが少なく、加熱速度も速くなる。Furthermore, when the peripheral edge of the bottom of each container is provided in a curved shape, it has a pressure deformation resistance against pressure fluctuation, so that it becomes a very stable container, and at the temperature rising point. Are dispersed, the heating unevenness is small and the heating rate is high.
【００４２】 また、前記容器本体の素材として、ＥＶＯＨからなる多層積層体を使用する場 合は、前記ＥＶＯＨの有するガスバリヤー特性や耐熱性にて、マイクロ波透過に 特に適した容器となると共に、廃棄処理の面やコストの面からも好ましいものと なる。When a multilayer laminate made of EVOH is used as the material of the container body, the gas barrier property and heat resistance of the EVOH make the container particularly suitable for microwave transmission.
