Description
本発明は、ハンバーグ、チキン、魚の切り身などのポーション状の食品を電子レンジで加熱して良好な食感が得られる様にする際に、食品に焦げ目やクリスピー感をきれいに付けるための電子レンジ加熱器具に関するものである。 The present invention is a method for heating portion-type foods such as hamburgers, chicken, and fish fillets in a microwave oven to give them a nice brown and crispy texture when heating them in a microwave oven to obtain a good texture. It concerns instruments.
従来、一度に使い切れる量、もしくは一口で食べきれる量にして、合成樹脂製のフィルムやアルミ箔等で個包装したポーション状の食品が各種上市されている。これらの食品は、保存上の観点から冷蔵または冷凍された状態で販売され、購入した消費者は食する際に適宜加熱して食感を良くしてから食される。加熱手段としては、近年は電子レンジを使用するのが一般的であることから、これらの食品を電子レンジで加熱しやすくする加熱器具も各種上市されている。 BACKGROUND ART Conventionally, various portion-shaped foods have been put on the market that are individually wrapped in synthetic resin film, aluminum foil, etc. in quantities that can be used at one time or eaten in one bite. These foods are sold in a refrigerated or frozen state for preservation purposes, and consumers who purchase them heat them appropriately to improve the texture before eating them. As a heating means, in recent years it has become common to use a microwave oven, and various heating appliances that make it easy to heat these foods in a microwave oven have also been put on the market.
例えば、図５の様に、板紙製のトレー状容器２０にサセプター（登録商標）と称される発熱シート２１を装着したものが知られている。サセプターは、電子レンジで発生するマイクロ波を吸収して熱に変換する作用を持つシートである。電子レンジは、通常の使い方では水の沸点である１００℃以上に加温することが難しいため、例えばハンバーグなどの食品をフライパンなどで加熱調理するときの様に焼き目や焦げ目をつけたり、クリスピー感を持たせるような調理が困難であるが、サセプターを使うことでより高温の状態が得られ、焼き目や焦げ目を付けることなどが可能になる。 For example, as shown in FIG. 5, a tray-shaped container 20 made of paperboard is equipped with a heat generating sheet 21 called a susceptor (registered trademark). A susceptor is a sheet that absorbs microwaves generated in a microwave oven and converts them into heat. In normal use, it is difficult for microwave ovens to heat water above 100℃, which is the boiling point of water. However, by using a susceptor, you can achieve a higher temperature, making it possible to grill or brown the food.
しかし図５の様なトレー状の容器２０では、サセプターに接しているハンバーグなどの食品１４の下面側には焦げ目が付けられるが、上面側には付けられないため、途中で上下をひっくり返すなどの手間が必要である。そこで、図６の様な台紙にサセプター３４を装着し、サセプター３４が内側となる様に折り目３５から折り返して内部に食品１４を収納し、食品１４を上下からサセプター３４で挟み込むようにした加熱容器３０も提案されている。厚みのある食品１４を収納しやすい様に、マチ３６を設け、また押さえ片３３を設けている。この様な加熱容器３０では、図７に示す様に皿１５に載せるなどして電子レンジで加熱することにより、ハンバーグなどの食品１４は下面側、上面側共にサセプターに接するため、両面に焼き目等を付けられるとしたものである。 However, in a tray-shaped container 20 as shown in FIG. 5, the bottom side of the food 14 such as a hamburger steak that is in contact with the susceptor is browned, but the top side is not browned, so it is difficult to brown the food 14, such as turning it upside down midway. It takes time and effort. Therefore, a heating container is constructed in which a susceptor 34 is attached to a mount as shown in FIG. 6, the food 14 is stored inside by folding it back from the crease 35 so that the susceptor 34 is on the inside, and the food 14 is sandwiched between the susceptor 34 from above and below. 30 has also been proposed. A gusset 36 and a pressing piece 33 are provided so that the thick food 14 can be easily stored. In such a heating container 30, when the food 14, such as a hamburger steak, is placed on a plate 15 and heated in a microwave oven as shown in FIG. etc. can be attached.
例えば特許文献１には、第１発熱体及び第２発熱体と、第１発熱体を支持する第１支持部と、第２発熱体を支持する第２支持部とを備え、第１支持部と第２支持部とが、第１発熱体上に載置された魚などに第２発熱体が接触するように屈曲可能に連結している加熱補助部材が開示されている。 For example, Patent Document 1 discloses that a first heating element, a second heating element, a first support part that supports the first heating element, and a second support part that supports the second heating element are provided, and the first support part A heating auxiliary member is disclosed in which the first heating element and the second support part are connected in a bendable manner so that the second heating element contacts a fish or the like placed on the first heating element.
また別の例として、例えば図８に示した様に、サセプター４４の食品への接触をより確実にするために、サセプター４４を設けたシート４１、４２にカバー４３を連設して図９の様にサセプター４４を設けたシート４１、４２に被せる様に重ねられる様にした加熱容器も提案されている。 As another example, for example, as shown in FIG. 8, in order to ensure the contact of the susceptor 44 with the food, a cover 43 is connected to the sheets 41 and 42 provided with the susceptor 44, as shown in FIG. Similarly, a heating container that can be stacked over sheets 41 and 42 provided with a susceptor 44 has also been proposed.
例えば特許文献２には、海苔の様なシート状の食品を、断面弧状のサセプターを設けた発熱シートと挟持板の間に挟み込んで加熱乾燥できるようにした電子レンジ加熱器具が開示されている。 For example, Patent Document 2 discloses a microwave heating device that can heat and dry a sheet-like food such as seaweed by sandwiching it between a heat-generating sheet provided with a susceptor having an arcuate cross-section and a clamping plate.
加熱する食品が海苔の様な可撓性のシート状の食品であれば、上述の様なサセプターを設けたシートに沿わせて効果的に加熱することが可能であるが、例えばハンバーグの様な、ある程度の厚みと体積を有し、かつ、その外形や表面性状にばらつきがある塊状（以下、これをポーション状と称する）の食品の場合、シート状のサセプターを台紙に貼着した形状の発熱器具の場合、これを湾曲させるなどしても、実際にサセプターのシートがポーション状の食品に直接接することができるのはわずかな点状の部分のみになってしまうため、電子レンジでの加熱では部分的に焦げ目を付けることはできるものの、ハンバーグなどの表面全体に綺麗に焼き目や焦げ目を付けるのが難しい、という問題があった。 If the food to be heated is a flexible sheet-like food such as seaweed, it can be effectively heated along a sheet provided with a susceptor as described above. In the case of bulk foods (hereinafter referred to as portions) that have a certain thickness and volume and have variations in their external shape and surface texture, a heat generating system in which a sheet-shaped susceptor is attached to a mount is used. In the case of utensils, even if the susceptor sheet is curved, only a small dot-like portion of the susceptor sheet can actually come into direct contact with the portioned food, so heating in a microwave oven is difficult. Although it is possible to partially brown the food, there was a problem in that it was difficult to properly brown or brown the entire surface of the hamburger steak.
そこで、上記の様な課題を解決するため、本発明は、可撓性を有する複数枚の挟持板が折り部を介して連接されてなる１枚の台紙を有し、
少なくとも１枚の前記挟持板の、前記折り部で折り返したときに内面側となる面に、電子レンジ加熱調理用発熱シートが貼合され、
前記電子レンジ加熱調理用発熱シートが貼合された前記挟持板のうち少なくとも１枚に、前記台紙および前記電子レンジ加熱調理用発熱シートの両方を貫通する複数のスリット状の切れ目により帯状に分割された発熱部が形成され、
複数枚の前記挟持板に挟み込まれた食品が、電子レンジマイクロ波照射による前記電子レンジ加熱調理用発熱シートの発熱を受けて加熱される構成を備えることを特徴とする電子レンジ加熱器具を提供するものである。
Therefore, in order to solve the above-mentioned problems, the present invention has a single mount formed by a plurality of flexible clamping plates connected via a folding part,
A heating sheet for heating in a microwave oven is pasted on the surface of at least one of the sandwiching plates that becomes the inner surface when folded back at the folding part,
At least one of the sandwiching plates to which the heat-generating sheet for microwave cooking is pasted is divided into strips by a plurality of slit-like cuts that penetrate both the mount and the heat-generating sheet for microwave cooking. A heat generating part is formed.
To provide a microwave oven heating appliance, characterized in that the food sandwiched between the plurality of sandwiching plates is heated by receiving heat generated from the heating sheet for microwave cooking by microwave microwave irradiation. It is something.
そして、本発明においては、前記食品を挟み込む挟持板のそれぞれに前記発熱部が設けられたものとすることが可能である。 In the present invention, each of the clamping plates that sandwich the food may be provided with the heat generating part.
また本発明においては、前記台紙は、坪量１００ｇ／ｍ２～５００ｇ／ｍ２の板紙からなるものとすることが可能である。 Further, in the present invention, the mount may be made of paperboard having a basis weight of 100 g/m 2 to 500 g/m 2 .
また本発明においては、前記電子レンジ加熱調理用発熱シートは、坪量１００ｇ／ｍ２～５００ｇ／ｍ２の電子レンジ加熱調理用発熱シートとすることが可能である。 Further, in the present invention, the heating sheet for heating in a microwave oven may have a basis weight of 100 g/m 2 to 500 g/m 2 .
また本発明においては、前記電子レンジ加熱調理用発熱シートはプラスチックフィルムに金属蒸着層を設けてなるものとすることが可能である。 Further, in the present invention, the heating sheet for heating in a microwave oven may be formed by providing a metal vapor-deposited layer on a plastic film.
本発明によれば、厚みや表面性状にばらつきのあるポーション状の食品を電子レンジで加熱調理する際に、食品を挟み込む挟持板のうち少なくとも１枚に、複数のスリット状の切れ目により帯状に分割された発熱部が形成されているため、帯状の発熱部がそれぞれに別かれてポーション状の食品のばらつきのある表面に当接しやすいため、食品の表面全体にわたって綺麗に焼き目や焦げ目を付けることができる電子レンジ加熱器具を得ることができる。 According to the present invention, when cooking portion-like foods with variations in thickness and surface texture in a microwave oven, at least one of the clamping plates that sandwich the food is divided into strips by a plurality of slit-like cuts. Since the heat-generating parts are formed in a single band, each band-shaped heat-generating part is separated and easily comes into contact with the uneven surface of the portion-shaped food, so it is possible to beautifully grill or brown the entire surface of the food. You can get a microwave heating appliance that can.
以下、本発明の実施の形態を、図面を参照しながら詳細に説明する。なお本発明は以下に説明する実施形態に限定されるものではない。また以下において同等の部材等には同じ符号を付して説明を省略することがある。 Embodiments of the present invention will be described in detail below with reference to the drawings. Note that the present invention is not limited to the embodiments described below. Further, in the following description, the same reference numerals may be given to the same members, and the description thereof may be omitted.
図１は、本発明の電子レンジ加熱器具の一形態の平面図である。電子レンジ加熱器具１は、紙を主材料とする台紙２に、電子レンジ加熱調理用発熱シート（以下、単に「発熱シート」とも記す）３を組み合わせて作成されてなる。また必要に応じ、接着層、印刷層、耐水層などを設けても良い。この電子レンジ加熱器具１は、折り部１１を介して連接されて見開き可能に折り重ねられる２枚の挟持板４、５と、挟持板４、５を折り重ねたときに互いに噛み合って挟持板４、５を係止する係止片８、９、一方の挟持板４から図１の上下方向に膨出する側片６、７を有している。 FIG. 1 is a plan view of one embodiment of the microwave oven heating appliance of the present invention. The microwave oven heating appliance 1 is made by combining a heat generating sheet 3 for microwave cooking (hereinafter also simply referred to as a "heat generating sheet") 3 to a mount 2 mainly made of paper. Further, an adhesive layer, a printed layer, a water-resistant layer, etc. may be provided as necessary. This microwave oven heating appliance 1 consists of two sandwiching plates 4 and 5 that are connected via a folding part 11 and folded together so that the two pages can be opened. , 5, and side pieces 6, 7 that bulge out in the vertical direction in FIG. 1 from one of the clamping plates 4.
そしてもう一方の挟持板５の略中央部には、複数のスリット状の切れ目１２が、所定長Ｌ１、所定間隔Ｌ２でもって設けられている。切れ目１２は台紙２と発熱シート３の両方を貫通して設けられているが、挟持板５の端縁部には達しておらず、そのため、その部分は互いに分離した複数の帯状の発熱部１３が形成された形態となっている。所定長Ｌ１、所定間隔Ｌ２は、挟持板４、５のサイズと共に、収納する食品の大きさなどに応じて適宜設定すれば良いが、食品が例えば通常の大きさのハンバーグであれば、Ｌ１は１００ｍｍ程度、Ｌ２は１０ｍｍ程度、切れ目の本数は７本程度とすると、ハンバーグの全体を帯状の発熱部１３でカバーできるため好ましい。 A plurality of slit-like cuts 12 are provided approximately at the center of the other holding plate 5 with a predetermined length L1 and a predetermined interval L2. Although the cut 12 is provided to penetrate both the mount 2 and the heat generating sheet 3, it does not reach the edge of the holding plate 5, and therefore, the cut 12 is formed by a plurality of band-shaped heat generating parts 13 separated from each other. It is a form that is formed. The predetermined length L1 and the predetermined interval L2 may be appropriately set according to the size of the holding plates 4 and 5 as well as the size of the food to be stored. However, if the food is a normal-sized hamburger, for example, L1 is It is preferable that the length is about 100 mm, L2 is about 10 mm, and the number of cuts is about 7 because the entire hamburger can be covered with the band-shaped heat generating part 13.
このとき、切れ目１２の方向と台紙２の紙目の方向を略一致させると、帯状の発熱部１３の強度が増し、ちぎれ難くなり好ましい。 At this time, it is preferable to make the direction of the cuts 12 substantially coincide with the direction of the paper grain of the mount 2, as this increases the strength of the band-shaped heat generating portion 13 and makes it difficult to tear.
また図１の例では、発熱シート３を台紙２の全面に設けているが、実際に食品の加熱に使用される部分のみに設ける様にしても良く、また所定の領域ごとに分割された形状の発熱シートとしても良い。 In addition, in the example of FIG. 1, the heat generating sheet 3 is provided on the entire surface of the mount 2, but it may also be provided only in the part actually used for heating food, or it may be divided into predetermined areas. It can also be used as a heat generating sheet.
図２は、図１の電子レンジ加熱器具にポーション状の食品を挟持した状態の斜視図である。また図３は、図１の電子レンジ加熱器具にポーション状の食品を挟持した状態の断面模式図である。ポーション状の食品１４（この例ではハンバーグ）は、一方の挟持板４の発熱シートを設けた面に載置され、他方の挟持板５を折り部１１で折り返して食品１４に重ね、係止片９を係止片８の凹部１０に噛み合わせて係止する。係止するための構造はこれに限定されるものではなく、図８の様な係止片をスリットに差し込む構造など、公知の構造を適宜採用すればよい。電子レンジで調理する際は適宜皿１５に載せるなどして加熱調理する。このとき側片６、７は、電子レンジ加熱器具１の持ち手ともなり、また若干上方に傾けた状態とすると、ハンバーグから流れ出る肉汁や水などがこぼれるのを防ぐこともできる。 FIG. 2 is a perspective view of the microwave heating device of FIG. 1 holding a portion-shaped food therebetween. Moreover, FIG. 3 is a schematic cross-sectional view of a state in which a portion-shaped food is held between the microwave oven heating appliance of FIG. 1. A portion-shaped food 14 (a hamburger in this example) is placed on the surface of one of the clamping plates 4 provided with the heat-generating sheet, and the other clamping plate 5 is folded back at the folding part 11 to overlap the food 14, and the locking piece is placed on the food 14. 9 is engaged with the recess 10 of the locking piece 8 to lock it. The structure for locking is not limited to this, and any known structure may be adopted as appropriate, such as a structure in which a locking piece is inserted into a slit as shown in FIG. When cooking in a microwave oven, heat the food by placing it on a plate 15 as appropriate. At this time, the side pieces 6 and 7 also serve as handles for the microwave oven heating appliance 1, and by tilting them slightly upward, it is possible to prevent meat juices, water, etc. from spilling from the hamburger steak.
電子レンジ加熱器具１は、ポーション状の食品１４を収納した状態において、挟持板５に設けられた帯状の発熱部１３が切れ目１２の部分で分離可能であるため、図３の断面図に示す様に個々の発熱部１３が食品１４のばらつきのある表面の形状に沿いやすくなる。この結果、発熱部１３の内面側の発熱シート３が食品１４のばらつきのある表面により的
確に当接されることとなり、食品１４のばらつきのある表面にムラなくきれいに焼き目、焦げ目を付けることが可能となる。またこのとき、個々の発熱部１３が食品１４のばらつきのある表面の形状に沿うことで、切れ目１２の間隔が広がり、電子レンジでの加熱調理の際に発生する水蒸気を効果的に排出することができるため、加熱した食品の表面をよりクリスピーでかりっとした仕上がりにすることができる。
In the microwave oven heating appliance 1, when the portion-shaped food 14 is stored, the band-shaped heat generating portion 13 provided on the clamping plate 5 can be separated at the cut 12, so that the heating device 1 can be heated as shown in the cross-sectional view of FIG. This makes it easier for the individual heat generating parts 13 to follow the shape of the uneven surface of the food product 14. As a result, the heat generating sheet 3 on the inner side of the heat generating part 13 comes into more accurate contact with the uneven surface of the food 14, and the uneven surface of the food 14 can be grilled and browned evenly and neatly. It becomes possible. In addition, at this time, the individual heat generating parts 13 follow the shape of the uneven surface of the food 14, so that the intervals between the cuts 12 are widened, and the water vapor generated during cooking in the microwave oven can be effectively discharged. This makes it possible to make the surface of heated foods crispier and crispier.
図４は本発明の電子レンジ加熱器具の別形態の平面図である。図４の実施形態では、スリット状の切れ目１２が、挟持板４、５の両方に設けられている。この様な形態とすると、図２と同様の態様としたとき、食品１４の下面側においても帯状の発熱部１３の発熱シート３がより的確に食品１４の表面に当接されることとなり、食品１４の表面全体をよりクリスピーでかりっとした仕上がりにすることができる。なお、このとき、食品１４の下面側は、自重により若干潰れて平坦になりやすいことなどを考慮して、下面側となる挟持板４の切れ目１２の間隔を広げて数を少なくしたり、長さを変えて設けるなどしても良い。 FIG. 4 is a plan view of another form of the microwave oven heating appliance of the present invention. In the embodiment of FIG. 4, slit-like cuts 12 are provided in both the clamping plates 4, 5. With this configuration, when the configuration is similar to that shown in FIG. 2, the heat generating sheet 3 of the band-shaped heat generating portion 13 is brought into contact with the surface of the food 14 more accurately even on the lower surface side of the food 14, and the food It is possible to make the entire surface of 14 more crispy and crunchy. At this time, taking into account that the lower side of the food 14 tends to be slightly crushed and flattened due to its own weight, the intervals between the cuts 12 in the clamping plate 4 on the lower side may be increased to reduce the number, or the number of cuts 12 may be reduced. It may be provided with different heights.
本発明の電子レンジ加熱器具１の台紙２としては、特に限定されず、公知の板紙を使用することができる。例えば、坪量１００～５００ｇ／ｍ２のバージン紙、カード紙などの板紙が使用できる。また耐油剤を紙層に添加したタイプの耐油紙が使用できる。具体的にはパールカード（２６０ｇ／ｍ２）などが例示できる。 The mount 2 of the microwave oven heating appliance 1 of the present invention is not particularly limited, and any known paperboard can be used. For example, paperboard such as virgin paper or card paper having a basis weight of 100 to 500 g/m 2 can be used. Also, a type of oil-resistant paper in which an oil-resistant agent is added to the paper layer can be used. A specific example is Pearl Card (260 g/m 2 ).
台紙２と発熱シート３との間に接着層を設ける場合には、例えば熱融着できる熱可塑性樹脂を用いることができる。例えば、直鎖状低密度ポリエチレン樹脂、低密度ポリエチレン樹脂、中密度ポリエチレン樹脂、高密度ポリエチレン樹脂、ポリプロピレン樹脂、ポリエチレンテレフタレート樹脂、ポリブチレンテレフタレート樹脂、メチルペンテンコポリマー、ポリアミド樹脂、ポリイミド樹脂などが挙げられる。 When providing an adhesive layer between the mount 2 and the heat-generating sheet 3, a thermoplastic resin that can be heat-sealed can be used, for example. Examples include linear low-density polyethylene resin, low-density polyethylene resin, medium-density polyethylene resin, high-density polyethylene resin, polypropylene resin, polyethylene terephthalate resin, polybutylene terephthalate resin, methylpentene copolymer, polyamide resin, polyimide resin, etc. .
ロール状の台紙２に、これらの熱可塑性樹脂を用いて、公知の方法である押出し機により接着層を連続して形成し、発熱シート３とサンドポリ加工して積層することができる。接着層の厚みは、１０～５０μｍの範囲が好ましい。 Using these thermoplastic resins, an adhesive layer is continuously formed on the roll-shaped mount 2 using an extruder, which is a known method, and the adhesive layer can be laminated with the heat-generating sheet 3 by sand-poly processing. The thickness of the adhesive layer is preferably in the range of 10 to 50 μm.
また接着剤を介して積層することもできる。例えば二液反応型のポリウレタン樹脂系接着剤を使用してドライラミネート法などの公知のラミネート方法を用いて積層することができる。 Alternatively, they can be laminated using an adhesive. For example, lamination can be performed using a two-component reactive polyurethane resin adhesive and a known lamination method such as dry lamination.
発熱シート３としては、サセプターが好適に用いられる。サセプターは、フィルム基材に金属蒸着加工によりマイクロ波発熱層を設けたもので、さらに接着層、保護層などが設けられている。フィルム基材としては、金属蒸着加工適性と電子レンジでの耐熱性を有していれば、特に種類を限定する必要はなく、発熱させようとする熱量に応じて選択すればよい。例えばポリエチレンテレフタレートフィルム、ポリブチレンテレフタレートフィルム、ポリブチレン２・６ナフタレートフィルム、ポリアミドフィルム、ポリイミドフィルムなどが挙げられる。またフィルム中には、各種添加剤、例えば帯電防止剤、滑剤、酸化防止剤などが添加されていても構わない。フィルムの厚みは特に限定されないが、金属蒸着加工などの機械加工適正を考慮した場合、６～１００μｍが望ましい。 As the heat generating sheet 3, a susceptor is suitably used. The susceptor has a microwave heating layer provided on a film base material by metal vapor deposition, and is further provided with an adhesive layer, a protective layer, etc. The film base material is not particularly limited in type as long as it has suitability for metal vapor deposition processing and heat resistance in a microwave oven, and may be selected depending on the amount of heat to be generated. Examples include polyethylene terephthalate film, polybutylene terephthalate film, polybutylene 2.6 naphthalate film, polyamide film, and polyimide film. Further, various additives such as antistatic agents, lubricants, antioxidants, etc. may be added to the film. The thickness of the film is not particularly limited, but it is preferably 6 to 100 μm in consideration of suitability for machining such as metal vapor deposition.
マイクロ波発熱層には、金属蒸着層を用いることができる。アルミニウム、スズ、亜鉛、鉄、銅などの蒸着薄膜およびアルミニウムと酸化アルミニウム混合層が考えられるが、発熱量および加熱時のスパークの問題からアルミニウムが好ましい。また価格性および生産性からアルミニウムが好ましい。アルミニウム蒸着の厚みとしては、４～５０ｎｍであれば効率よく発熱する。 A metal vapor-deposited layer can be used as the microwave heating layer. Although vapor-deposited thin films of aluminum, tin, zinc, iron, copper, etc. and mixed layers of aluminum and aluminum oxide are conceivable, aluminum is preferable due to the problem of heat generation and sparks during heating. Further, aluminum is preferable from the viewpoint of cost and productivity. If the thickness of aluminum vapor deposition is 4 to 50 nm, heat will be generated efficiently.
サセプターは、サセプターとして市販されているものを用いることができる。具体的にはサセプター＃１２（凸版印刷製）などが例示できる。 A commercially available susceptor can be used as the susceptor. Specifically, Susceptor #12 (manufactured by Toppan Printing Co., Ltd.) can be exemplified.
