した。また電子レンジで料理された後にガラス容器ある
いは陶器自体も高温となり、取扱いに＜＜、特に一度に
大計の調理をしなければならないレストランや機内食な
どでは大変な作業であった。With the spread of microwave ovens, cooked foods and frozen foods have become widespread in ordinary households. These cooked foods are packaged in plastic film, but when thawing or reheating them in a microwave oven, the plastic film used for packaging has poor heat resistance, so they cannot be packaged in glass containers or XR"a. It took a lot of effort to transfer the food.Furthermore, the glass containers or ceramics themselves become hot after being cooked in the microwave, making handling difficult, especially in restaurants or in-flight meals where large amounts of food must be cooked at once. Met.
本発明の目的は調理済食品を電子レンジにより再加熱調
理する際にガラス容器あるいは陶器に移しかえる必要が
なくそのまま再加熱調理のできる耐熱性、保温性、剛性
に優れた新規な食品用容器を提供することにある。The purpose of the present invention is to provide a new food container with excellent heat resistance, heat retention, and rigidity that allows cooked food to be reheated in a microwave oven without having to be transferred to a glass container or ceramic container. It is about providing.
本発明者らは上記の目的を達成すべく鋭意研究を重ねた
結果、本発明に到達した。The present inventors have conducted extensive research to achieve the above object, and as a result, have arrived at the present invention.

率が１．１倍以上の発泡シートを熱成形してなる耐熱性
、保温性、剛性に優れた電子レンジ用容器である。That is, the present invention is made by thermoforming a foamed sheet consisting of 99 to 50% by weight of a polyolefin resin and 1 to 50% by weight of an inorganic filler and having an expansion ratio of 1.1 times or more, which has excellent heat resistance, heat retention, and rigidity. It is a container for microwave oven.

上では容器の表面光沢が低下し軽量性にも劣る０本発明
では特に５〜２０重世％の範囲が好ましい。In the present invention, the inorganic filler is polyolefin resin 99
The filler is blended at a ratio of 1 to 50% by weight to 50% by weight. If the proportion of the inorganic filler is less than 1% by weight, the effect of improving heat resistance and rigidity will not be sufficient. In addition, if it exceeds 50% by weight, the surface gloss of the container decreases and the lightness is also poor.In the present invention, a range of 5 to 20% by weight is particularly preferred.

ントロールすることができる。The foaming ratio in the present invention is the value obtained by dividing the density of an unfoamed sheet made of the polyolefin resin and inorganic filler by the density of a foamed sheet of the same composition, and in the present invention, the foaming ratio is 1.1 times or more. If the zero expansion ratio is preferably less than 1.1 times, the effect of improving heat retention and lightness is not sufficient.The zero expansion ratio can be arbitrarily controlled by the amount of the blowing agent added to the composition consisting of the polyolefin resin and the inorganic filler. Can be done.
本発明に用いられる発泡剤としては一般に市販されてい
るものが使用可能であり、例えば、アブビスイソブチロ
ニトリル、アゾジカルボンアマイド、トルエンスルホニ
ルヒドラジド、Ｎ、Ｎ’−ジニトロソペンタメチレンテ
