Description

レンジ加熱用包装容器Range heating packaging container
　この発明は、レンジ加熱用包装容器に関し、特に、枝豆や米，シュウマイなどのように蒸気で蒸らすことが要請される冷凍食品に好適なレンジ加熱用包装容器に関するものである。 This invention relates to a range heating packaging container, and more particularly to a range heating packaging container suitable for frozen foods that are required to be steamed with steam, such as green soybeans, rice, and shumai.
　調理済あるいは半調理済等の冷凍食品、たとえば、肉まんやあんまん、シュウマイ、餃子、ハンバーガー、ホットドック、スパゲティー、焼きそば、焼きうどん、ビーフン等の調理済めん類等をプラスチック製の包装袋等の包装容器に収納し、食べるに際して電子レンジにより加熱調理する包装食品が市場に提供されている。 Frozen foods such as cooked or semi-cooked foods, such as meat noodles, annman, shumai, dumplings, hamburgers, hot dogs, spaghetti, fried noodles, fried noodles, rice noodles, etc. in plastic packaging bags etc. Packaged foods that are cooked and cooked in a microwave oven when stored and eaten are provided on the market.
　この種の食品を収納する包装容器は、電子レンジで包装体ごと加熱すると、食品から発生する蒸気や内部空気の熱膨張により包装体の内圧が上昇し、突然に包装容器が破断して、包装容器内に収納された食品が飛散すると共に、電子レンジ内を汚すといった問題があった。 When a packaging container that contains this type of food is heated together with the package in a microwave oven, the internal pressure of the package rises due to the thermal expansion of steam and internal air generated from the food, and the packaging container suddenly breaks and the packaging There was a problem that food stored in the container was scattered and the inside of the microwave oven was soiled.
　このような問題を解決するために、従来から、電子レンジで加熱調理する前に、通常はあらかじめ包装容器に尖ったもので孔を開けたり、包装容器の端部をはさみなどで切り取るなどして、加熱した際に包装容器の内圧を逃がして破断するのを防止していた。 In order to solve such problems, conventionally, before cooking in a microwave oven, usually a hole is made in the packaging container in advance, or the end of the packaging container is cut off with scissors etc. When heated, the internal pressure of the packaging container was released to prevent breakage.
　しかし、このような手段で内圧を逃がすことは、手間がかかるとともに、加熱調理が開始されて発生した蒸気が、直ちに包装容器外へ放出されると、蒸気による加熱蒸らし効果が期待されている食品では、味が落ちる。 However, releasing the internal pressure by such means is time consuming, and when the steam generated by the start of cooking is immediately released to the outside of the packaging container, a food that is expected to have a steaming effect by heating with steam. Then the taste goes down.
　そこで、例えば、特許文献１には、このような問題が解決することができる包装容器が提案されている。この特許文献１に開示されている包装容器は、内層に易剥離性を有する熱接着性樹脂層からなる包装材を熱接着部で密封した包装体において、包装体の内側周縁部の少なくとも１箇所に、内側周縁部から包装体の内側に張り出して熱接着された張出部を有し、この張出部に切刃もしくは切欠が形成されていることを特徴としている。 Therefore, for example, Patent Document 1 proposes a packaging container that can solve such a problem. The packaging container disclosed in Patent Document 1 is a package in which a packaging material made of a heat-adhesive resin layer having an easily peelable inner layer is sealed with a heat-bonding portion, and at least one place on the inner peripheral edge of the package Further, it has an overhanging portion that protrudes from the inner peripheral edge to the inside of the package and is thermally bonded, and a cutting blade or a notch is formed in the overhanging portion.
　このように構成した包装容器によれば、調理済あるいは半調理済等の食品を完全に密封できると共に、食品を包装体に収納したままで電子レンジにより加熱調理すると、張出部が包装体の内側に張り出していることにより、内層に設けられた易接着性の部分が、その他の熱接着部より速く剥離するために包装体内の内部圧力を、張出部に設けられた切刃もしくは切欠より自動的に逃がして破裂を防止することができるとともに、加熱調理中に発生する蒸気により包装体に収納された食品を蒸らす効果も得られることになる。 According to the packaging container configured in this way, cooked or semi-cooked food can be completely sealed, and when the food is cooked with a microwave oven while being stored in the package, the overhanging portion of the package is Since the easily adhesive part provided in the inner layer is peeled off faster than other heat-bonded parts, the internal pressure in the package is less than the cutting blade or notch provided in the protruding part. While being able to escape automatically and preventing explosion, the effect of steaming the food stored in the package by steam generated during cooking is also obtained.
　しかしながら、このような従来の包装容器には、以下に説明する課題があった。 However, such conventional packaging containers have the following problems.
特開平１１－２０８７３９号公報Japanese Patent Laid-Open No. 11-208739
　すなわち、上記特許文献に開示されている包装容器では、内層に設けられた易接着性の部分が、その他の熱接着部より速く剥離するために、包装体内の内部圧力を自動的に逃がすことができるが、少なくとも２層構造の包装容器にしか適用することができないので、容器の材料選択の自由度がなく、また、内部に収納する食品の種類や量などによって、圧力開放のために放出する蒸気量を変えようとする場合に、これに対応することが難しいという問題があった。 That is, in the packaging container disclosed in the above-mentioned patent document, the easy-adhesive part provided in the inner layer peels faster than the other heat-bonding parts, so that the internal pressure in the packaging body can be automatically released. Although it can be applied only to packaging containers with at least two-layer structure, there is no freedom in selecting the material of the container, and it is released to release pressure depending on the type and amount of food stored inside. When changing the amount of steam, there was a problem that it was difficult to cope with this.
　本発明は、このような問題点に鑑みてなされたものであって、その目的とするところは、容器の材料選択の自由度が大きく、かつ、圧力開放のために放出する蒸気量の調節が簡単に行える包装容器を提供することにある。 The present invention has been made in view of such problems, and its object is to provide a large degree of freedom in selecting the material of the container and to adjust the amount of steam released for pressure release. It is to provide a packaging container that can be easily performed.
　上記目的を達成するために、本発明は、未調理，調理済，半調理済の食品を内部に収納する容器本体と、前記容器本体の開口部を閉止して、前記食品を封入する熱シール線と、前記熱シール線の内側に、所定の間隙を隔てて形成される破断停止シール線とを有し、前記熱シール線を破断して、前記容器本体の内外を連通させた状態で加熱する際に、前記容器本体の前記熱シール線の内側に到達する破断個所を前記破断停止シール線に留め、前記熱シール線と前記破断停止シール線との間の間隙を内外連通孔とするようにした。 In order to achieve the above object, the present invention provides a container main body for storing uncooked, cooked, and semi-cooked food, and a heat seal for closing the opening of the container main body and enclosing the food. And a break stop seal line formed at a predetermined gap inside the heat seal line, and the heat seal line is broken and heated in a state where the inside and outside of the container body are communicated with each other. In this case, a breakage point that reaches the inside of the heat seal line of the container body is fastened to the break stop seal line, and a gap between the heat seal line and the break stop seal line is used as an internal / external communication hole. I made it.
　このように構成したレンジ加熱用包装容器によれば、熱シール線を破断して、容器本体の内外を連通させた状態で加熱する際に、容器本体の熱シール線の内側に到達する破断個所を破断停止シール線に留め、熱シール線と破断停止シール線との間の間隙を内外連通孔とするので、容器本体の材料が、特別なもので形成する必要がなく、材料選択の自由度が大きく、かつ、圧力開放のために放出する蒸気量の調節は、内外連通孔の大きさ、すなわち、熱シール線と破断停止シール線との間の間隙の大きさを変更することにより簡単に行える。 According to the range heating packaging container configured in this way, when the heat seal wire is broken and heated in a state where the inside and outside of the container body are in communication, the breakage point that reaches the inside of the heat seal wire of the container body Since the gap between the heat seal line and the break stop seal line is used as an internal / external communication hole, it is not necessary to form the container body with a special material, and the degree of freedom in material selection The amount of steam released for pressure release is easily adjusted by changing the size of the internal and external communication holes, that is, the size of the gap between the heat seal line and the break stop seal line. Yes.
　前記容器本体は、底辺に閉止部が設けられ、対向する２側辺に折曲線，熱シール線，熱刃溶着線などの開封誘導部が設けられ、上辺に開口部が設けられた偏平な形態を備え、前記開口部から前記食品を収容して、前記開口部を前記閉止部と直交するように前記熱シール線を設けて閉塞して、４つの三角形を連接した四面立体形状とすることができる。 The container body has a flat shape in which a closing portion is provided on the bottom side, an opening inducing portion such as a fold line, a heat seal wire, a hot blade welding wire is provided on two opposing sides, and an opening portion is provided on the upper side. The food is received from the opening, and the opening is closed by being provided with the heat seal wire so as to be orthogonal to the closing portion, thereby forming a four-dimensional solid shape in which four triangles are connected. it can.
　前記破断停止シール線は、前記開封誘導部と直交するように形成することができる。 The break stop seal line can be formed so as to be orthogonal to the opening guide portion.
　前記熱シール線は、前記破断停止シール線の形成個所で、外方側にＶ字ないしはＵ字状に屈曲形成され、この屈曲部分に前記破断停止シール線を配置することができる。 The heat seal line is bent at an outer side where it is formed in a V shape or a U shape, and the break stop seal line can be disposed at the bent portion.
　前記食品は、枝豆，シューマイなどのように蒸気で、一定時間蒸らすことが期待されている冷凍食品から選択することができる。 The food can be selected from frozen foods that are expected to be steamed for a certain period of time, such as edamame and shumai.
　本発明に係るレンジ加熱用包装容器によれば、容器の材料選択の自由度が大きく、かつ、圧力開放のために放出する蒸気量の調節が簡単に行える。 According to the packaging container for range heating according to the present invention, the degree of freedom in selecting the material of the container is large, and the amount of steam released for releasing the pressure can be easily adjusted.

　以下、本発明の好適な実施の形態について、添付図面に基づいて詳細に説明する。図１～図４は、本発明に係るレンジ加熱用包装容器の一実施例を示している。これらの図に示したレンジ加熱用包装容器は、調理済あるいは半調理済等の冷凍食品１２、例えば、肉まんやあんまん、シュウマイ、餃子、ハンバーガー、ホットドック、スパゲティー、焼きそば、焼きうどん、ビーフン等や、未調理の冷凍食品や、例えば、冷凍枝豆などが内部に収納される容器本体１０を有している。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 4 show an embodiment of a packaging container for heating range according to the present invention. The range heating packaging containers shown in these figures are frozen foods 12 such as cooked or semi-cooked, such as meat buns, buns, shumai, dumplings, hamburgers, hot dogs, spaghetti, yakisoba, baked udon, rice noodles, etc. It has the container main body 10 in which uncooked frozen food, for example, frozen green soybeans, etc. are stored.
　図１は、食品１２を投入する前の容器本体１０を示しており、この容器本体１０は、底辺に閉止部１６が設けられ、対向する２側辺に開封誘導部１８が設けられ、上辺に開口部２０が設けられた長方形状の偏平な形態を備えている。 FIG. 1 shows a container body 10 before the food 12 is introduced. The container body 10 is provided with a closing portion 16 on the bottom side, an opening guide portion 18 on two opposite sides, and on the upper side. The flat shape of the rectangular shape provided with the opening part 20 is provided.
　本実施例の場合、容器本体１０は、電子レンジでの加熱に耐え得る耐熱性を備えていれば、特に材質は問わないが、例えば、ポリプロピレン系の合成樹脂フィルムや、これに紙や蒸着フィルムを貼り付けた複層ラミネートフィルムを用いることができる。また、合成樹脂フィルムの場合には、透明，半透明，不透明のいずれでもよい。 In the case of the present embodiment, the material of the container body 10 is not particularly limited as long as it has heat resistance that can withstand heating in a microwave oven. It is possible to use a multi-layer laminate film on which is attached. In the case of a synthetic resin film, it may be transparent, translucent, or opaque.
　開封誘導部１８は、内部に収納されている食品を取り出す際に、破断を容易にするために用いられるものであり、本実施例の場合には、袋状の容器本体１０を形成する際に必要となる側部の裁断線を利用して、開封の容易性を確保している。この開封誘導部１８は、例えば、熱シール線で２枚のフィルムを線状に溶着することや、２枚のフィルムを熱刃で切断しながら端面同士を熱刃溶着線とすることができる。 The opening guide 18 is used for facilitating breakage when taking out food contained therein, and in the case of the present embodiment, when forming the bag-like container body 10.

When the food 12 is put into and accommodated in the container body 10, first, as shown in FIG. 2, the centers C and C ′ of the opening 20 of the container body 10 made of two sheets of paper are separated from each other. Then, the opening 20 is expanded and the food 12 is put inside.
　食品１２が投入されると、次に、角部Ａと同Ｂとを近接させて、角部Ａ，Ｂとが一致するようにして、容器本体１０のフィルム同士を直線状に熱溶着させる熱シール線２２を形成することにより、フィルム同士を接着して開口部２０を閉塞する。 When the food 12 is introduced, next, the corners A and B are brought close to each other so that the corners A and B coincide with each other. By forming the seal line 22, the films 20 are bonded together to close the opening 20.
　このようにして容器本体１０を閉塞すると、熱シール線２２による閉塞部は、容器本体１０の底辺の閉止部１６と直交することになり、このような閉塞部を設けると、図３に示すように、４つの三角形が形成される。 When the container main body 10 is closed in this way, the closed portion due to the heat seal line 22 is orthogonal to the closing portion 16 on the bottom side of the container main body 10, and when such a closed portion is provided, as shown in FIG. Four triangles are formed.
　すなわち、この三角形は、熱シール線２２を共通底辺とする三角形ＣＥＣ’と同ＣＤＣ’、および、閉止部１６を共通底辺とする三角形ＤＣＥと同ＤＣ’Ｅであり、これらの４つの三角形は、周方向に沿って相互に連接されていて、四面立体形状になる。 That is, this triangle is a triangle CEC 'and the same CDC' having the heat seal line 22 as a common base, and a triangle DCE and a DC'E having a common bottom as the closing portion 16, and these four triangles are They are connected to each other along the circumferential direction to form a tetrahedral shape.
　この場合、開封誘導線１８は、熱シール線２２を共通底辺とする三角形ＣＥＣ’と同ＣＤＣ’の頂点から底辺に向かう垂線上にあって、耳部２４を通って開口部２０の上端まで到達している。開封誘導線１８が到達する耳部２４の端縁には、破断を開始させるためのノッチ２６が設けられている。 In this case, the opening guide line 18 is on a perpendicular line from the apex of the triangle CEC ′ and the CDC ′ having the heat seal line 22 as the common base to the base, and reaches the upper end of the opening 20 through the ear 24. is doing. A notch 26 for starting breakage is provided at the edge of the ear 24 where the opening guide line 18 reaches.
　さらに、本実施例の場合には、図３（Ｂ）に、図３（Ａ）中のａ部を拡大して示すように、熱シール線２２の内側に所定の間隙ｄを隔てて、破断停止シール線３０が設けられている。 Further, in the case of the present embodiment, as shown in FIG. 3 (B) in an enlarged view of a part in FIG. 3 (A), the fracture is caused by separating a predetermined gap d inside the heat seal line 22. A stop seal line 30 is provided.
　破断停止シール線３０は、熱シール線２２と同様に、熱溶着により形成され、本実施例の場合には、開封誘導線１８上に中心が位置し、その左右方向が熱シール線２２と平行になるように延設されていて、全長は、例えば、１０ｍｍ程度に形成される。このような破断停止シール線３０を設けると、熱シール線２２と破断停止シール線３０との間の間隙ｄが、食品１２を加熱する際の内外連通孔３２となる。 The break stop seal line 30 is formed by heat welding similarly to the heat seal line 22, and in the case of the present embodiment, the center is located on the opening guide line 18, and the left-right direction thereof is parallel to the heat seal line 22. The total length is, for example, about 10 mm. When such a breakage stop seal line 30 is provided, the gap d between the heat seal line 22 and the breakage stop seal line 30 becomes the inner and outer communication holes 32 when the food 12 is heated.
　以上のように構成されたレンジ加熱用包装容器を、例えば、電子レンジで加熱する際には、容器本体１０の内外を連通させるために、容器本体１０を部分的に破断することになる。 For example, when the packaging container for heating a range configured as described above is heated in a microwave oven, the container body 10 is partially broken in order to communicate the inside and outside of the container body 10.
　この破断に際しては、本実施例の場合、まず、ノッチ２６の部分から容器本体１０を破断し、破断を開封誘導線１８に沿って、容器本体１０の内部側に延長し、熱シール線２２を破断した後に、破断停止シール線３０に留める。 In the case of this breakage, in the case of the present embodiment, first, the container body 10 is broken from the portion of the notch 26, the break is extended along the opening guide line 18 to the inside of the container body 10, and the heat seal line 22 is connected. After breaking, it is fastened to the break stop seal line 30.
　このようにして、破断停止シール線３０に到達する破断を行うと、熱シール線２２と破断停止シール線３０との間の間隙ｄが、内外に連通し、その結果この部分が内外連通孔３２となる。 In this way, when a break that reaches the break stop seal line 30 is performed, the gap d between the heat seal line 22 and the break stop seal line 30 communicates with the inside and outside, and as a result, this portion becomes the inside / outside communication hole 32. It becomes.
　このような状態で、容器本体１０を電子レンジ内に投入して、誘導加熱を行うと、食品１２から発生した蒸気は、一部が内外連通孔３２から外部に放出されて、容器本体１０の内圧を逃がして破断するのを防止するとともに、熱の拡散を防ぎ、所定の圧力が加えられた状態で食品１２を加熱し、香りの発散も防ぐことができる。 In such a state, when the container body 10 is put into the microwave oven and induction heating is performed, a part of the steam generated from the food 12 is released to the outside from the inner and outer communication holes 32, and the container body 10 While preventing internal pressure from escaping and preventing breakage, heat diffusion is prevented, and the food 12 is heated in a state in which a predetermined pressure is applied, thereby preventing fragrance from spreading.
　なお、この場合の容器本体１０内の圧力と、外部に放出する蒸気との関係は、内外連通孔３２の大きさにより調節することが可能で、加熱対象食品１２の性状や量などに応じて適宜変更することができる。 In this case, the relationship between the pressure in the container main body 10 and the vapor released to the outside can be adjusted by the size of the inner and outer communication holes 32, depending on the properties and amount of the food 12 to be heated. It can be changed as appropriate.
　この場合、特に、食品１２として、枝豆，シューマイなどのように蒸気で、一定時間蒸らすことが期待されている冷凍食品を選択すると、本実施例の加熱包装容器の効果がより一層顕著に発揮される。 In this case, in particular, when a frozen food that is expected to be steamed for a certain period of time with steam, such as edamame and shumai, is selected as the food 12, the effect of the heat-packaging container of the present embodiment is more remarkably exhibited. The
　そして、この後、所定時間加熱した後に、開封誘導部１８を介して、破断停止シール線３０を越えて、容器本体１０をさらに破断する。この場合、例えば、開封誘導部１８を左右の手指で挟んで、引き裂くようにすれば、開封誘導部１８は簡単に破れて、三角形ＣＥＣ’と同ＣＤＣ’は、それぞれ半割状態になる。 After that, after heating for a predetermined time, the container body 10 is further broken through the opening guide part 18 over the breaking stop seal line 30. In this case, for example, if the opening guide part 18 is sandwiched between the left and right fingers and torn, the opening guide part 18 is easily broken, and the triangle CEC 'and the CDC' are in a halved state.
　四面立体形状の容器本体１０の三角形ＣＥＣ’と同ＣＤＣ’が半割状態になると、容器本体１０は、図４に示すように、閉止部１６を共通底辺とする２つの三角形ＤＣＥと同ＤＣ’Ｅを連結した概略菱形形状が底辺となり、その側縁に三角形ＣＥＣ’と同ＣＤＣ’とを半割状態にした４つの三角形が立ち上がる容器形状になり、この容器形状内に、食品１２が収容され、これを食することが可能になる。 When the triangle CEC ′ and the same CDC ′ of the quadrilateral three-dimensional container body 10 are halved, as shown in FIG. 4, the container body 10 has two triangles DCE and DC ′ having the closing portion 16 as a common base. A roughly rhombus shape that connects E becomes the base, and four triangles that divide the triangle CEC 'and the CDC' into the half are raised on the side edges, and the food 12 is contained in this container shape. It will be possible to eat this.
　さて、以上のように構成されたレンジ加熱用包装容器によれば、熱シール線２２を破断して、容器本体１０の内外を連通させた状態で加熱する際に、容器本体１０の熱シール線２２の内側に到達する破断個所を破断停止シール線３０に留め、熱シール線２２と破断停止シール線３０との間の間隙ｄを内外連通孔３２とするので、容器本体１０の材料を、特別なもので形成する必要がなく、材料選択の自由度が大きく、かつ、圧力開放のために放出する蒸気量の調節は、内外連通孔３２の大きさ、すなわち、熱シール線２２と破断停止シール線３０との間の間隙ｄの大きさを変更することにより簡単に行える。 Now, according to the range heating packaging container configured as described above, when the heat sealing wire 22 is broken and heated in a state where the inside and outside of the container body 10 are in communication, the heat sealing wire of the container body 10 is used. 22, the breakage point that reaches the inside of the wire 22 is fastened to the breakage stop seal line 30, and the gap d between the heat seal wire 22 and the breakage stop seal line 30 is used as the inner and outer communication holes 32. There is no need to form the material, the degree of freedom of material selection is great, and the amount of steam discharged for pressure release is adjusted by adjusting the size of the inner and outer communication holes 32, that is, the heat seal wire 22 and the break stop seal. This can be done easily by changing the size of the gap d between the line 30 and the line 30.
　図５は、本発明に係るレンジ加熱用包装容器の他の実施例を示しており、上記実施例と同一もしくは相当する部分には、同一ないしは対応する符号を付してその説明を省略するとともに、以下にその特徴点についてのみ説明する。 FIG. 5 shows another embodiment of the packaging container for heating range according to the present invention.

　破断停止シール線３０ａは、その中心が開封誘導部１８上にあって、左右方向の両端部は、熱シール線２２ａから所定の間隙ｄを隔てて位置に設けられている。本実施例の場合、この間隙ｄが容器本体１０を破断した際の内外連通孔３２ａとなる。このように構成した実施例においても、上記実施例と同等の作用効果が得られる。なお、本実施例における熱シール線２２ａの屈曲形状は、Ｖ字形に限る必要はなく、例えば、Ｕ字形や半円あるいは矩形であってもよい。 The center of the rupture stop seal line 30a is on the opening guide part 18, and both ends in the left-right direction are provided at positions spaced apart from the heat seal line 22a by a predetermined gap d. In the case of the present embodiment, this gap d becomes the inner and outer communication holes 32a when the container body 10 is broken. Also in the embodiment configured as described above, the same effects as those of the above-described embodiment can be obtained. It should be noted that the bent shape of the heat seal wire 22a in the present embodiment is not limited to the V shape, and may be, for example, a U shape, a semicircle, or a rectangle.
　また、上記実施例では、本発明を４つの三角形を連接した四面立方体形状の包装容器に適用した場合を例示したが、本発明の実施は、これに限定されるものではなく、レンジ加熱用の包装容器で熱シールの封止構造を採用するものに適用することができる。 In the above embodiment, the case where the present invention is applied to a four-sided cube-shaped packaging container in which four triangles are connected is illustrated.
