Description
本発明は食品を収納するための包装容器に関し、未開封の状態で電子レンジで加熱することにより、発生する水蒸気による蒸らし効果に加えて、食品に焦げ目をつけることもできる包装容器に関する。 The present invention relates to a packaging container for storing food, and relates to a packaging container capable of browning food in addition to the steaming effect of steam generated by heating in an unopened state in a microwave oven.
食品類を収納した包装袋を電子レンジで加熱した際に、発生する水蒸気の圧力によって、包装袋が破裂したり、内容物が飛散したりしないように、水蒸気の圧力を逃がす機構（通蒸機構）を備えた包装袋が知られている。特許文献１に記載された包装材料及び包装製品は、水蒸気の圧力によって生じた小穴が水蒸気の発生量に応じて拡大縮小し、内圧を常圧以上に維持することができる包装材料である。この包装材料によれば、一定時間加熱を継続することができるため、蒸らし調理が可能である。 A mechanism that releases the pressure of water vapor so that the packaging bag does not burst or the contents are scattered due to the pressure of water vapor generated when the packaging bag containing foods is heated in a microwave oven (steaming mechanism). ) Is known as a packaging bag. The packaging material and the packaging product described in Patent Document 1 are packaging materials capable of maintaining the internal pressure at a normal pressure or higher by expanding or contracting the small holes generated by the pressure of water vapor according to the amount of water vapor generated. According to this packaging material, heating can be continued for a certain period of time, so that steam cooking is possible.
一方、電子レンジによる加熱によって食品に焦げ目をつけたり、ぱりぱり感を出したりする技術が知られている。特許文献２に記載された電子レンジ加熱用容器は、マイクロ波により発熱する発熱体を使用した容器である。 On the other hand, there is known a technique for browning or giving a crisp feeling to food by heating with a microwave oven. The microwave oven heating container described in Patent Document 2 is a container using a heating element that generates heat by microwaves.
食品の種類によっては、例えば冷凍の餃子などのように、蒸し調理と焦げ目付けとの両方の調理方法が必要とされるものがある。しかし単純に上記の容器と包装袋とを組み合わせただけでは、発熱体の発生する高熱により外装の包装袋が溶融して容器に密着してしまうため、使用することができなかった。 Some types of food, such as frozen dumplings, require both steaming and browning methods. However, simply combining the above container and the packaging bag cannot be used because the outer packaging bag melts due to the high heat generated by the heating element and adheres to the container.
本発明の解決しようとする課題は、蒸らし調理と焦げ目をつける調理の両方の機能を両立させた包装容器を提案するものである。 An object to be solved by the present invention is to propose a packaging container that has both functions of steaming cooking and browning cooking.
上記の課題を解決するための手段として請求項１に記載の発明は、食品を収納し、未開封の状態で電子レンジで加熱することのできる包装容器であって、食品を載置する内装容器と、内装容器を収納する外装袋とを有し、内装容器は耐熱性を有する基材の食品が接する面に、マイクロ波の照射によって発熱する発熱体を備えており、外装袋は最外層となる二軸延伸フィルム層と、中間層となるポリオレフィン系樹脂層と、最内層となるセルロースパルプを混抄した熱可塑性樹脂不織布とが積層された積層体からなり、包装容器の上部に水蒸気放出口を有することを特徴とする包装容器である。 The invention according to claim 1 as a means for solving the above-mentioned problems is a packaging container that can store food and can be heated in a microwave oven in an unopened state, and is an interior container on which food is placed. The inner container is equipped with a heating element that generates heat by irradiation with microwaves on the surface of the heat-resistant base material that comes into contact with the food, and the outer bag is the outermost layer. It is composed of a laminate in which a biaxially stretched film layer, a polyolefin resin layer as an intermediate layer, and a thermoplastic resin non-woven fabric obtained by mixing cellulose pulp as an innermost layer are laminated, and a steam discharge port is provided at the upper part of the packaging container. It is a packaging container characterized by having.
本発明に係る包装容器は、外装袋の最内層に耐熱性の高いセルロースパルプを混抄した熱可塑性樹脂不織布を用いたことにより、加熱による外装袋の融着を防止することができる。 In the packaging container according to the present invention, by using a thermoplastic resin non-woven fabric in which highly heat-resistant cellulose pulp is mixed and extracted for the innermost layer of the outer bag, fusion of the outer bag due to heating can be prevented.
また、請求項２に記載の発明は、前記水蒸気放出口が、前記積層体の最外層と最内層を貫通する傷加工であることを特徴とする請求項１に記載の包装容器である。 The invention according to claim 2 is the packaging container according to claim 1, wherein the steam discharge port is a scratch process that penetrates the outermost layer and the innermost layer of the laminated body.
また、請求項３に記載の発明は、熱可塑性樹脂不織布を構成する熱可塑性樹脂がポリオレフィン系樹脂であることを特徴とする請求項１または２に記載の包装容器である。 The invention according to claim 3 is the packaging container according to claim 1 or 2, wherein the thermoplastic resin constituting the thermoplastic resin non-woven fabric is a polyolefin resin.
また、請求項４に記載の発明は、収納する食品が焼餃子であることを特徴とする請求項１〜３のいずれか１項に記載の包装容器である。 The invention according to claim 4 is the packaging container according to any one of claims 1 to 3, wherein the food to be stored is gyoza.
本発明に係る包装容器は、マイクロ波の照射によって発熱する発熱体を備えた内装容器と、これを収納する外装袋とからなり、外装袋の最内層に耐熱性の高いセルロースパルプを混抄した熱可塑性樹脂不織布を配置したことにより、電子レンジ加熱した際に、外装袋の内面が溶融して内装容器や食品に溶着してしまう現象が生じない。 The packaging container according to the present invention comprises an inner container provided with a heating element that generates heat by irradiation with microwaves and an outer bag for accommodating the inner container, and heat is obtained by mixing cellulose pulp having high heat resistance in the innermost layer of the outer bag. By arranging the plastic resin non-woven fabric, the phenomenon that the inner surface of the outer bag melts and is welded to the inner container or food does not occur when the bag is heated in the microwave.
外装袋には水蒸気放出口が設けられているため、加熱により外装袋が破裂することはない。また水蒸気放出口を積層体の最外層と最内層を貫通する傷加工とした場合には、傷加工の長さによって水蒸気放出量を任意に制御することが可能であり、最適な蒸らし調理が容易に実現できる。 Since the outer bag is provided with a steam discharge port, the outer bag does not burst due to heating. In addition, when the steam discharge port is a scratch process that penetrates the outermost layer and the innermost layer of the laminated body, the amount of steam release can be arbitrarily controlled by the length of the scratch process, and optimum steam cooking is easy. Can be realized.
本発明に係る包装容器は、焼餃子のように、蒸らしと焦げ目の両方の調理が必要な食材を収納するのに最適に使用できる。 The packaging container according to the present invention can be optimally used for storing foodstuffs that require both steamed and browned cooking, such as gyoza.
以下図面を参照しながら、本発明に係る包装容器について詳細に説明する。図１は、本発明に係る包装容器１の一実施態様を示した斜視図である。また図２は、図１の状態から包装容器１を開封して外装袋２０を除去し、内装容器１０に食品３０が載置された状態を示した斜視図である。また図３は、本発明に係る包装容器１の外装袋２０に使用する積層体２１の一実施態様を示した断面説明図である。図４は、本発明に係る包装容器１の内装容器１０に使用する積層体の一実施態様を示した断面説明図である。 The packaging container according to the present invention will be described in detail with reference to the following drawings. FIG. 1 is a perspective view showing an embodiment of the packaging container 1 according to the present invention. Further, FIG. 2 is a perspective view showing a state in which the packaging container 1 is opened from the state of FIG. 1, the outer bag 20 is removed, and the food 30 is placed on the inner container 10. Further, FIG. 3 is a cross-sectional explanatory view showing an embodiment of the laminate 21 used for the outer bag 20 of the packaging container 1 according to the present invention. FIG. 4 is a cross-sectional explanatory view showing an embodiment of a laminate used for the inner container 10 of the packaging container 1 according to the present invention.
本発明に係る包装容器１は、食品を収納し、未開封の状態で電子レンジで加熱することのできる包装容器であって、食品３０を載置する内装容器１０と、これを収納する外装袋２０とからなる。内装容器１０は耐熱性を有する基材１１の食品３０が接する面に、マイクロ波の照射によって発熱する発熱体１２を備えており、外装袋２０は最外層となる二軸延伸フィルム層２２と、中間層となるポリオレフィン系樹脂層２３と、最内層となるセルロースパルプを混抄した熱可塑性樹脂不織布２４とが積層された積層体２１からなる。包装容器１の上部には、水蒸気放出口２５を有する。 The packaging container 1 according to the present invention is a packaging container that stores food and can be heated in a microwave oven in an unopened state, and is an inner container 10 on which the food 30 is placed and an outer bag that stores the interior container 10. It consists of 20. The inner container 10 is provided with a heating element 12 that generates heat by irradiation with microwaves on the surface of the heat-resistant base material 11 that comes into contact with the food 30, and the outer bag 20 includes a biaxially stretched film layer 22 that is the outermost layer. It is composed of a laminate 21 in which a polyolefin-based resin layer 23 as an intermediate layer and a thermoplastic resin non-woven fabric 24 obtained by mixing cellulose pulp as an innermost layer are laminated. The upper part of the packaging container 1 has a steam discharge port 25.
図１に示した例では、外装袋２０が、底面に合掌シール部を有するピロー包装袋であるが、包装袋の形状については特に制約はなく、三方シール袋や四方シール袋、ガセットピロー包装袋など任意である。 In the example shown in FIG. 1, the outer bag 20 is a pillow packaging bag having a gassho seal portion on the bottom surface, but there are no particular restrictions on the shape of the packaging bag, and a three-way seal bag, a four-way seal bag, or a gusset pillow packaging bag. Etc. are optional.
図３は、外装袋２０を構成する積層体２１の一例を示した断面説明図である。積層体２１としては、少なくとも最外層となる二軸延伸フィルム層２２と、中間層となるポリオレフィン系樹脂層２３と、最内層となるセルロースパルプを混抄した熱可塑性樹脂不織布２４とが積層された積層体が使用される。図では省略されているが、二軸延伸フィルム層２２の表面または裏面には通常印刷層が設けられる。また必要に応じて各層を積層するための接着剤層が設けられる。 FIG. 3 is a cross-sectional explanatory view showing an example of the laminated body 21 constituting the outer bag 20. The laminate 21 is a laminate in which at least a biaxially stretched film layer 22 as an outermost layer, a polyolefin-based resin layer 23 as an intermediate layer, and a thermoplastic resin non-woven fabric 24 obtained by mixing cellulose pulp as an innermost layer are laminated. The body is used. Although omitted in the drawing, a normal printing layer is usually provided on the front surface or the back surface of the biaxially stretched film layer 22. Further, if necessary, an adhesive layer for laminating each layer is provided.
最外層となる二軸延伸フィルム層２２には、通常、印刷加工が施されるため、印刷加工適性に優れた二軸延伸フィルムが用いられる。二軸延伸フィルムとしては、一般的なポリエチレンテレフタレート樹脂（ＰＥＴ）フィルムや二軸延伸ポリプロピレン樹脂（ＯＰＰ）フィルムの他、更なる耐熱性が必要な場合には、ポリブチレンテレフタレート樹脂（ＰＢＴ）フィルム、ポリカーボネート樹脂フィルム、ポリ塩化ビニリデン樹脂フィルム、三酢酸セルロース樹脂フィルム、ナイロンフィルム等の各種耐熱性フィルムを使用することができる。 Since the biaxially stretched film layer 22 as the outermost layer is usually subjected to printing processing, a biaxially stretched film having excellent print processing suitability is used. Biaxially stretched films include general polyethylene terephthalate resin (PET) film and biaxially stretched polypropylene resin (OPP) film, as well as polybutylene terephthalate resin (PBT) film when further heat resistance is required. Various heat-resistant films such as a polypropylene resin film, a polyvinylidene chloride resin film, a cellulose triacetate resin film, and a nylon film can be used.
中間層となるポリオレフィン系樹脂層２３としては、低密度ポリエチレン樹脂（ＬＤＰＥ）、中密度ポリエチレン樹脂（ＭＤＰＥ）、直鎖状低密度ポリエチレン樹脂（ＬＬＤＰＥ）、エチレン−酢酸ビニル共重合体（ＥＶＡ）、エチレン−αオレフィン共重合体、エチレン−メタアクリル酸樹脂共重合体などのエチレン系樹脂や、ポリエチレンとポリブテンのブレンド樹脂や、ホモポリプロピレン樹脂（ＰＰ）、プロピレン−エチレンランダム共重合体、プロピレン−エチレンブロック共重合体、プロピレン−αオレフィン共重合体などのポリプロピレン系樹脂等が使用される。 The polyolefin-based resin layer 23 to be the intermediate layer includes low-density polyethylene resin (LDPE), medium-density polyethylene resin (MDPE), linear low-density polyethylene resin (LLDPE), ethylene-vinyl acetate copolymer (EVA), and the like. Ethylene-based resins such as ethylene-α-olefin copolymers and ethylene-methacrylic acid resin copolymers, blended resins of polyethylene and polybutene, homopolypropylene resin (PP), propylene-ethylene random copolymers, propylene-ethylene Polypropylene-based resins such as block copolymers and propylene-α-olefin copolymers are used.
最内層となる熱可塑性樹脂不織布２４としては、前述のポリオレフィン系樹脂層２３に用いられると同様の材料から得られるファイバーを主成分として、これにセルロースパルプを混抄した不織布を用いることができる。セルロースパルプは、加熱しても溶融することがないので、これを外装袋２０の最内層に用いた場合、電子レンジで加熱されても最内層が溶融して内装容器や食品に付着することを防止することができる。 As the thermoplastic resin non-woven fabric 24 to be the innermost layer, a non-woven fabric in which a fiber obtained from the same material as that used for the polyolefin resin layer 23 described above is used as a main component and cellulose pulp is mixed with the fiber can be used. Cellulose pulp does not melt even when heated, so when it is used for the innermost layer of the outer bag 20, the innermost layer melts and adheres to the inner container and food even when heated in a microwave oven. Can be prevented.
但し、積層体２１を外装袋２０に製袋する場合に、最内層の熱可塑性樹脂不織布２４同士が加熱されてシーラントとしての役割を果たす必要があるので、セルロースパルプの混抄率は、３０％〜７０％程度が好ましい。 However, when the laminate 21 is made into the outer bag 20, the thermoplastic resin non-woven fabrics 24 in the innermost layer need to be heated to serve as a sealant, so that the mixing ratio of the cellulose pulp is 30% or more. About 70% is preferable.
水蒸気放出口２５としては、例えば予め積層体に設けた貫通孔を脆弱なシールで封止する方法や、包装袋のシール部の一部に狭幅の脆弱な部分を設ける方法など、さまざまな形態が可能であり、特に制約されるものではないが、本発明の外装袋の場合、３層からなる積層体を用いているので、最外層と最内層を貫通する傷加工２６を設ける方法が最も簡単でしかも安定した方法である。 The water vapor discharge port 25 has various forms such as a method of sealing a through hole provided in a laminated body in advance with a fragile seal, a method of providing a narrow fragile portion in a part of a sealing portion of a packaging bag, and the like. However, in the case of the outer bag of the present invention, since a laminated body consisting of three layers is used, the method of providing the scratch processing 26 penetrating the outermost layer and the innermost layer is the most suitable. It's an easy and stable method.
傷加工には、刃物を用いる方法や、レーザー加工機を用いる方法を使用することができる。この方法によれば、傷の長さを調節することで、開口部の大きさを適当な大きさに設定することができるので、適切な蒸らし時間を保持することが可能である。 For scratch processing, a method using a cutting tool or a method using a laser processing machine can be used. According to this method, the size of the opening can be set to an appropriate size by adjusting the length of the wound, so that an appropriate steaming time can be maintained.
図２は、図１の状態から包装容器１を開封して外装袋２０を除去し、内装容器１０に食品３０が載置された状態を示した斜視図である。内装容器１０としては、厚紙などのように耐熱性を有する基材１１に、マイクロ波によって発熱する発熱体１２を部分的に設けた
トレー状の容器を用いる。発熱体１２としては、サセプターと呼ばれるＰＥＴフィルムのような耐熱性の基材フィルムにアルミニウムなどの金属を蒸着した蒸着フィルムを用いることができる。発熱体１２は、食品を載置するのに必要な最小限の面積に設ける。
FIG. 2 is a perspective view showing a state in which the packaging container 1 is opened from the state of FIG. 1, the outer bag 20 is removed, and the food 30 is placed in the inner container 10. As the inner container 10, a tray-shaped container in which a heating element 12 that generates heat by microwaves is partially provided on a base material 11 having heat resistance such as thick paper is used. As the heating element 12, a vapor-deposited film in which a metal such as aluminum is vapor-deposited on a heat-resistant base film such as a PET film called a susceptor can be used. The heating element 12 is provided in the minimum area required for placing food.
本発明に係る包装容器は、以上のように蒸らす調理と焦げ目をつける調理の両方を同時に行うことができるので、図２に示した焼餃子などの食品を収納するのに最適なものである。 Since the packaging container according to the present invention can simultaneously perform both steaming cooking and browning cooking as described above, it is most suitable for storing foods such as grilled dumplings shown in FIG.
