Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は，電子レンジで調理するレトルト食品を収納す
る容器に関するものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a container for storing retort food to be cooked in a microwave oven.
最近，電子レンジで調理するいわゆるレトルト食品が数
多く出回っており，このレトルト食品を収納する容器
も，収納するレトルト食品に対応した様々な構造となっ
ている。その中の一つに，容器本体の開口部にフィルム
体をヒートシールして密封するものがある。その場合，
フィルムのシール強度は，約2.3kg/15mm巾が必要とさ
れ，この強度でシールされたとき，開封時には非常に大
きな力が必要である。Recently, a large number of so-called retort foods cooked in a microwave oven are available on the market, and containers for storing the retort foods have various structures corresponding to the stored retort foods. One of them is one in which the film body is heat-sealed and sealed at the opening of the container body. In that case,
The sealing strength of the film is required to be about 2.3 kg / 15 mm width, and when sealing with this strength, a very large force is required when opening.
上記した容器本体とそれを密封するフィルム体とから成
る容器においては，調理する場合，加熱によって容器内
に発生する蒸気の逃げ口の大きさが適当でないため，加
熱によって容器内に発生する蒸気の逃げ口がないと内圧
が上がり，容器が変形したり，シール部が破れたりして
内容物が容器内に飛散するため，必ず逃げ口は必要であ
り，そしてその逃げ口の大きさが適当でないためうまく
調理できなかったり，又，調理後，フィルム体の取り除
きに大変強い強い力を要するといった問題があった。In a container composed of the container body and a film body that seals the container body described above, when cooking, the size of the escape port for the steam generated in the container by heating is not appropriate, so the steam generated in the container If there is no escape port, the internal pressure will rise, the container will be deformed, the seal part will be broken, and the contents will scatter into the container. Therefore, the escape port is always necessary, and the size of the escape port is not appropriate. Therefore, there was a problem that it could not be cooked well, or that it took a very strong force to remove the film body after cooking.
本考案は，上記の問題を解決する容器を提供するもので
ある。The present invention provides a container that solves the above problems.
そのため，有底筒形状体の上端外周に鍔部３を形成した
容器本体１と，周端よりやや内方部分を、鍔部３上面に
溶着あるいは接着によって密着して、容器本体１を密閉
する、二軸延伸成形された合成樹脂製フィルム体２と、
から構成し、 フィルム体２の，前記鍔部３と密着する密着部４より外
側部分である周端部に，フィルム体２の前記両延伸方向
に対してほぼ45度の角度に沿った一対の切断線６によっ
て開封片５を形成した。Therefore, the container body 1 in which the flange portion 3 is formed on the outer periphery of the upper end of the bottomed tubular body and the portion slightly inward of the peripheral edge are adhered to the upper surface of the flange portion 3 by welding or adhesion to seal the container body 1. A biaxially stretched synthetic resin film body 2,
The film body 2 is provided with a pair of circumferential edges, which are outside the contact portion 4 that is in close contact with the collar portion 3, at an angle of approximately 45 degrees with respect to both the stretching directions of the film body 2. The unsealing piece 5 was formed by the cutting line 6.
上記した本考案による容器の作用を，以下説明する。 The operation of the container according to the present invention will be described below.
電子レンジで調理する前に，第１図に示す状態の容器
を，第２図に示すように，開封片５を指でつまみ上げて
容器本体１の中心方向に向かって引く。これによって，
フィルム体２の一対の切断線６がその仮想延長線上より
やや相互に内方に向かって引き裂かれ，第３図に示すよ
うに三角形の空気孔７が形成される。Before cooking in a microwave oven, as shown in FIG. 2, the container in the state shown in FIG. 1 is picked up by the fingers of the opening piece 5 and pulled toward the center of the container body 1. by this,
The pair of cutting lines 6 of the film body 2 are torn slightly inward from each other on the imaginary extension lines, and triangular air holes 7 are formed as shown in FIG.
この場合，切断線６がフィルム体２の延伸方向にほぼ45
度の角度に沿って形成されているので，空気孔７は第３
図に示すように，常に一定した適度な大きさに形成され
ることが出来る。In this case, the cutting line 6 is approximately 45 in the stretching direction of the film body 2.
Since it is formed along the angle of degrees, the air holes 7
As shown in the figure, it can be formed to have a constant and appropriate size.
ちなみに，あらゆる実験の結果，切断線６の向きを，例
えばフィルム体２の延伸方向と同一方向に形成した場
合，形成される空気孔７の形状および大きさは力加減お
よび力の作用方向によって異なり，その大きさも本願の
ものよりかなり大きくなってしまい，常に，一定した空
気孔７を形成することは不可能であるという結論が得ら
れた。By the way, as a result of all experiments, when the direction of the cutting line 6 is formed in the same direction as the stretching direction of the film body 2, the shape and size of the air holes 7 formed are different depending on the force control and the acting direction of the force. It was concluded that the size of the air holes 7 was considerably larger than that of the present invention, and it was impossible to always form a constant air hole 7.
空気孔７を形成した後，電子レンジ内に入れて調理する
際，加熱によって発生する蒸気は，この適度の大きさに
形成された空気孔７から外に逃げることが出来るので，
良い調理が出来る。After the air holes 7 are formed, the steam generated by heating can be escaped to the outside from the air holes 7 formed to have an appropriate size when being put in a microwave oven for cooking.
You can cook well.
又，調理後のフィルム体２の取り除きは，先に取り除か
れた開封片５部分から左部分と右部分に分けて取り除く
ことによって，軽い力で楽に行えるものとなる。Further, the removal of the film body 2 after cooking can be easily performed with a light force by removing the opening piece 5 portion removed previously separately into the left portion and the right portion.
〔実施例〕 本考案の一実施例を，図を参照しながら説明する。[Embodiment] An embodiment of the present invention will be described with reference to the drawings.
フィルム体２は，熱可塑性樹脂製フィルムを積層したも
のが望ましい。本実施例においては，延伸されると機械
的強度等，優れた特性を発揮するポリエチレンテレフタ
レート樹脂製フィルムに耐熱性の高いナイロンを積層し
たものである。このフィルム体２の構成物質は，限定さ
れるものではなく，要求に応じて適宜設定するものであ
る。The film body 2 is preferably a laminate of thermoplastic resin films. In this example, a polyethylene terephthalate resin film that exhibits excellent properties such as mechanical strength when stretched is laminated with nylon having high heat resistance. The constituent material of the film body 2 is not limited and is appropriately set according to the demand.
本実施例における容器本体１は，ポリプロピレン樹脂製
であるが，これも限定されるものではない。The container body 1 in this embodiment is made of polypropylene resin, but is not limited to this.
開封片５の幅は，要求する空気孔７の大きさによって適
宜設定されるものであるが，本実施例の場合，外側から
内側に向けて狭くなるテーパ状とし，外端の幅を約15m
m,そして密着部４に接する内端の幅を約9mmとしてい
る。この場合，開封片５を約0.9kgの力で引き裂き，空
気孔７を形成することが可能である。この場合，フィル
ム体２の肉厚は，約0.1mmに設定し，鍔部３に対する密
着は，ヒートシールで行っている。この場合，周辺部の
シール強度は，平均で3.0kg/15mm巾および2.3kg/15mm巾
であった。The width of the unsealing piece 5 is appropriately set depending on the size of the air hole 7 required, but in the case of this embodiment, it is tapered so that it becomes narrower from the outside toward the inside, and the width of the outer end is about 15 m.
m, and the width of the inner end in contact with the contact portion 4 is about 9 mm. In this case, it is possible to tear the opening piece 5 with a force of about 0.9 kg and form the air hole 7. In this case, the thickness of the film body 2 is set to about 0.1 mm, and the close contact with the collar portion 3 is performed by heat sealing. In this case, the peripheral seal strength was 3.0 kg / 15 mm width and 2.3 kg / 15 mm width on average.
尚，第１図における矢印は，フィルム体２の二軸延伸方
向を示すものである。The arrow in FIG. 1 indicates the biaxial stretching direction of the film body 2.
第４図は，別の実施例を示すものである。FIG. 4 shows another embodiment.
切断線６およびそれによって形成される開封片５の形状
が，第１図に示す実施例と異なるが，形成される空気孔
７はほぼ同じであり，又，調理後のフィルム体２の取り
除きも同様に簡単である。Although the shape of the cutting line 6 and the opening piece 5 formed thereby is different from that of the embodiment shown in FIG. 1, the air holes 7 formed are almost the same, and the film body 2 can be removed after cooking. It's just as easy.
尚，切断線６は，完全に切断されたものに限定するもの
ではなく，軽い力で切断される例えば点線状のものや，
ほぼ切断された状態まで深く切り込まれた線状のもので
あっても良い。The cutting line 6 is not limited to a completely cut line, but may be a line cut by a light force, for example, a dotted line,
It may be a linear shape that is deeply cut into a substantially cut state.
このように，本考案は，常に，しかも簡単に調理に必要
な適度な大きさの空気孔を形成することが出来ると共
に，調理後のフィルム体の取り除きも軽い力で楽に行え
るといった優れた効果を発揮する。As described above, the present invention has an excellent effect that it is possible to always and easily form an air hole of an appropriate size necessary for cooking, and to easily remove the film body after cooking with a light force. Demonstrate.
