Description of the Related Art Conventionally, when cooking in a microwave oven, a special microwave oven cooking vessel such as a molded vessel made of a heat-resistant synthetic resin material is used, or a dish or the like is used. In general, the material was placed in the container and covered with a wrap film.

た問題があった。However, when these containers are used, it is necessary to clean up the cooking containers after cooking, and the containers are bulky, which requires a large storage space when not in use. There was a problem that disposal was difficult.

【０００４】そのため、近年、耐熱性のある合成樹脂フ
ィルムによる袋を、電子レンジでの調理袋として利用す

得られない。However, when the cooking bag is simply a flat bag, the self-standing of the cooking ingredients such as ingredients and seasoning liquid is unstable, and the seasoning liquid or soup stock may overflow. In addition, the convection effect of seasoning liquid or soup stock during heating and cooking is poor, and the ingredients do not evenly permeate into the ingredients, and uneven heating tends to occur, and satisfactory heating and seasoning effects can be obtained. Absent.

は到底満足できるものではない。Further, it is considered to use a self-supporting bag as shown in Japanese Patent Publication No. 59-44261, for example, as a cooking bag in a microwave oven. In the case of this proposed bag,
Since the cooking ingredients are stored in the lower part of the bag, which has a relatively flat expanse due to the wing portions projecting forward and backward, the convection effect during cooking is poor, and it is not completely satisfactory in terms of heating and seasoning effects. .

なり、使い捨てする調理袋としては適さない。[0008] Therefore, it is necessary to perform a simple sealing that does not impair the air permeability. For this simple sealing, a dedicated closing means such as an adhesive tape, a clip or a fastener is used separately from the bag. Is required, and it is difficult to close it so that it has breathability suitable for cooking,
The sealing operation becomes troublesome. Providing a special sealing means in the opening of the bag itself increases the manufacturing cost of the bag itself and is not suitable as a disposable cooking bag.
