。Problems to be Solved by the Invention As a pressure cooking container for a microwave oven, there are problems such as uneven irradiation of microwaves, presence of substances (especially oil) whose temperature rises abnormally due to selective absorption of microwaves, and incorrect energization of the heater in a microwave oven equipped with an oven function. In consideration of abnormal temperature rise due to
, 2 kg/cd), it is required that there be no contamination (discoloration, decrease in mechanical strength, etc.) by various cooking products.

があった。However, with conventional materials, there is discoloration (color difference of 4 or more) due to food cooked under pressure cooking conditions (e.g. curry, soy sauce, etc.) and a significant decrease in mechanical strength (mainly due to hydrolysis: pressure cooking test). , 120°C/
The tensile strength retention rate was 50% after 100 hours, which was a practical problem.

に向上する。Means for Solving the Problems In order to solve the above problems, the pressure cooking container for a microwave oven of the present invention is made of a microwave-transparent resin having heat resistance and pressure resistance, and the inside is filled with food to be cooked. It is a molded structure that can maintain pressure above atmospheric pressure, and at least the inner surface of the molded structure that comes into contact with the food to be cooked is coated with a fluororesin. Function: The pressure cooking container for microwave ovens according to the present invention is made of a microwave-transparent resin having heat resistance and pressure resistance, and its inner surface is coated with a fluorine-based resin, so that the chemical resistance is greatly improved.
実施例
以下、本発明の電子レンジ用圧力調理容器の一実施例に
ついて説明する。EXAMPLE Hereinafter, an example of the pressure cooking container for microwave oven of the present invention will be described.

えばポリ４弗化エチレンで被覆されている。The pressure cooking vessel is a molded structure made of semi-crosslinked polyphenylene sulfide resin (hereinafter referred to as PPs resin) reinforced with glass fiber (40 wt%) as a microwave-transparent resin, and the inner surface is made of a fluorine-based resin such as Coated with polytetrafluoroethylene.
上記構成において、ＰＰＳ樹脂は連続使用温度２２０゜
Ｃ以上の耐熱性と十分な耐圧性（これともっとも関係す

上）と圧力調理条件（１２０゜Ｃ、２ｋｇ／ｃｄ）下、
各種調理物による変色および調理物内の水による強度低
下の度合いは少なくこれだけでも十分実用に耐え得る（
色差２以内、プレッシャークンカーテスト前記温度１０
００時間後の強度保持率７０％以上）と思われるが、こ
の表面に弗素系樹脂を被覆したものは色素１以内で強度
保持率８５％以上とさらに特性が向上する。In the above configuration, the PPS resin has heat resistance at a continuous use temperature of 220°C or more, sufficient pressure resistance (the mechanical property most related to this is tensile strength, which is 1500kg/cIIY or more), and pressure cooking conditions (120°C, 2kg /cd) below,
The degree of discoloration due to various types of food and the decrease in strength due to water in the food is small, and this alone is sufficient for practical use (
Color difference within 2, Pressure Kunker test above temperature 10
It is thought that the strength retention rate after 00 hours is 70% or more), but when the surface is coated with a fluorine-based resin, the strength retention rate is 85% or more within 1 dye, which further improves the properties.
このため、前記圧力調理容器を長期間の実用に際して安

脂を用いたがこれに限定するものではなく、耐熱水性の
不十分な樹脂も含めて広範囲な樹脂に適用できる。Therefore, the pressure cooking container can be used safely for a long period of time. Although PPS resin was used in the above embodiments, the present invention is not limited to this, and can be applied to a wide range of resins, including resins with insufficient hot water resistance.
