【考案の詳細な説明】 ［産業上の利用分野］ 本考案は、密封した食品を電子レンジでそのまま加熱
することのできる包装体に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a package that can directly heat a sealed food in a microwave oven.
［従来の技術］ 食品は、通常プラスチックフィルム製の袋内に密封し
て流通されることが多い。このような食品を電子レンジ
でそのまま加熱する場合には、あらかじめ針で穴をあけ
たり、ハサミで一部をカットしたり、一部を切り裂いた
りして内圧を逃すようにしている。[Related Art] Foods are often distributed in a sealed state in a plastic film bag. When such a food is directly heated in a microwave oven, the internal pressure is released by making holes in advance with a needle, cutting a part with scissors, or cutting a part.
［従来技術の課題］ このため、そはに針やハサミがないと不便である。
又、うっかり穴等をあけるのを忘れて加熱すると、内圧
で大きな破裂音を立てて破裂したり、この際に内容物が
飛散したりすることがある。[Problems of the prior art] For this reason, it is inconvenient unless the needle has needles or scissors.
In addition, if heating is performed without inadvertently opening a hole or the like, a large bursting sound may be generated due to the internal pressure, or the contents may be scattered.
一方、食品の加熱に際しては、ある範囲で内圧がかか

る。 本考案は、斯る点に鑑みて提案されるもので、密
封状態のままで電子レンジにかけても大きな音を立てて
破袋したりしないと共に、ある範囲までは内圧を保って
ふっくらと加熱することができると共に、加熱時間の短
縮化つまり省エネ化を図った点に特徴がある。On the other hand, when the food is heated, if the internal pressure is applied in a certain range, the food can be heated plumply. Also, there is an advantage that cooking time can be reduced when an internal pressure is applied. The present invention is proposed in view of such a point, and does not make a loud noise even if it is microwaved in a sealed state and does not break the bag, and also heats up to a certain range while maintaining the internal pressure. The feature is that the heating time is shortened, that is, energy saving is achieved.
［課題を解決するための手段］ 本考案の構成は次のとおりである。[Means for Solving the Problems] The configuration of the present invention is as follows.

して成る電子レンジ用包装体。Using a laminated film having an innermost layer of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 6 to 19% by weight and an MI of 1 to 20 g / 10 min, a bag is made by a heat sealing method, and the heat sealing width is partially reduced. A microwave oven package formed narrower than the others.

かったり、ヒートシール強度が十分でなかったりする
で、実用的にはこの範囲が良好である。[Operation] The above-mentioned package is sealed as a bag of an arbitrary shape by a heat sealing method. When the food thus sealed is heated in a microwave oven, it can be directly placed in a refrigerator and directly heated. Due to this heating, the internal pressure first increases, and the innermost layer, that is, the heat seal layer, starts melting,
When the internal pressure and the seal strength are reversed, the heat seal layer separates and the internal pressure (steam) escapes from here. This exit position is where the heat seal width is narrower than the others and the seal strength is weak. This action is performed gradually as the melting of the innermost layer progresses, and is never performed sharply.
However, vinyl acetate content is 6 to 19% by weight, MI is 1 to 20g / 10m
If it exceeds the range of in, the melting is too fast, that is, the internal pressure does not rise sufficiently, or the heat sealing property is deteriorated, or the heat sealing strength is insufficient, so that this range is practically good. is there.

The width of the heat-sealed portion 2 of the package 1 is 10 m / m. However, a narrow portion (steam escape portion) 3 of 5 m / m is formed in a part thereof.

裂音を立てたり、内容物が飛散したりすることがない。[Effects of the Invention] As described above, the present invention provides a microwave oven package in which the innermost layer contains vinyl acetate in an amount of 6 to 19% by weight and an MI of 1 to 20 g / 10 min.
Of ethylene vinyl acetate copolymer was placed and sealed by a heat sealing method. As a result, when heating is started in the microwave oven, the internal pressure first increases, and at the same time, the melting of the innermost layer proceeds, and the steam eventually escapes from the narrow heat-sealed portion. This action is never performed suddenly due to the action of the ethylene-vinyl acetate copolymer, so that no loud popping noise is generated and the contents are not scattered.

くらとおいしく加熱できる利点がある。Therefore, there is an advantage that the package for a microwave oven is convenient because it does not require time and effort at the time of heating, and since the internal pressure is applied first, it can be heated plumply and deliciously.

の自動販売化はできなかった。In addition, since it can be heated in a microwave oven while it is sealed, when coins are inserted in the vending machine, the microwave oven inside the machine directly heats the sealed food, remove it from the outlet and open it, and eat it easily Is possible.
Therefore, according to the present invention, it is possible to enhance the automatic sales of foods heated by a microwave oven. In this regard, conventionally, since it is not possible to heat the food as it is in a microwave oven, it has not been possible to automatically sell the food heated in a microwave oven with a vending machine.
