<p>Provided is a package for cooking in a microwave oven, in which a synthetic resin container body having a flange part is filled with contents and a lid is heat-sealed to the flange part to seal the package hermetically. Independent concave parts sandwiching a heat-sealed part are provided in a part of the flange part on the inner and outer sides of the heat-sealed part to form, on the heat-sealed part, a projection part directed to the inner direction of the container and serving as a steam releasing part by automatically opening. The package is prevented from being broken or deformed by preventing the heat-sealed part from being peeled immediately after the contents are placed in the container body. When heating cooking is performed in a microwave oven, the package improves the taste of the contents by the steaming effect. The lid is sure to automatically open by the increase of the pressure in the container.</p> |
