放出する穴を開けるか、または容器内の食品を別の容器
に移し替えて加熱調理するようにしていた。Therefore, conventionally, in order to avoid such a situation as described above, when cooking such food, a hole for releasing water vapor is made in advance in a sealed container, or the food in the container is transferred to another container. I changed it and cooked it.
しかしながら、加熱調理前に上述のように移し替えや、
穴を開ける操作をすることは、消費者にとって手間がか
かり、電子レンジ食品本来の目的からすれば必ずしも良
好な調理方法とは言い難いものであった。However, before cooking, transfer as described above,
The operation of making a hole is troublesome for the consumer, and is not necessarily a good cooking method from the original purpose of microwave food.
従って本考案の目的は、電子レンジで加熱調理する際

出穴２ｂに熱が加わらないように取付けるようにする。More specifically, the thin-shaped polynorbornene-based shape memory polymer as the shape memory material 4 has a width of 6 m.
It is formed to have a length of m, a length of 12 mm, and a thickness of 1 mm, and is formed by memorizing a shape of curling into a cylindrical shape having a diameter of about 3 mm by heating. The sealing material 3 is formed in a square shape with one side of 20 mm. Then, the sealing material 3 to which the shape memory material 4 is attached is attached to the water vapor discharge hole 2b having a diameter of about 10 mm so that heat is not applied.

熱調理される。Therefore, when the frozen food etc. in the microwave food container 1 of this embodiment is electronically heated by the microwave oven, the shape memory material 4 is heated by the heat of the steam generated from the food,
The shape memory material 4 is gradually peeled off from the lid 2a of the container of the seal material 3 and curled, and is restored to the previously stored cylindrical shape. As a result, the water vapor discharge hole 2b sealed by the sealing material 3 is exposed to release the water vapor that is accumulating in the container 2, and the food is appropriately cooked without the container 2 expanding and bursting.
