PROBLEM TO BE SOLVED: To easily provide various delicious simmered dishes by storing raw food materials and seasoning liquids separately in a bag for adding heat for a predetermined period of time, in a home-use electronic microwave oven.SOLUTION: In a part of a plastic sealing bag consisting of inner thermal fusion layer, a first weak heat-fusion line is provided, which performs weak heat-fusion of the front and backside films, resulting in the formation of a food material storage section and a seasoning liquid storage section, with the seasoning liquid storage section storing seasoning liquids therein, and the food material storage section contains chopped food materials for cooking. On one sides of the food material storage section that does not come in contact with the seasoning liquid storage section, at least two heat-fusion lines that have a gap between them are provided, each has an opening at the end part separated from the plurality of the heat-fusion lines and does not come in contact with the first weak heat-fusion line, a second weak heat-fusion line being preferably provided on the inside of one of the plurality of heat-fusion lines located at the innermost part from among them, the peel strength of the first weak heat-fusion line is equal to or greater than the peel strength of the second weak heat-fusion line that is provided on the inside from the heat-fusion line located at the innermost part.COPYRIGHT: (C)2007,JPO&INPIT【課題】生の食材と調味液とを分離して1つの袋に収納し、家庭用の電子レンジで所定時間加熱することにより、美味しい各種煮物を簡易に提供する。【解決手段】内面熱融着性層からなるプラスチック製密封袋の一部を、表裏のフィルムを弱融着する第1の弱融着線により食材収納部と調味液収納部が形成され、該調味液収納部に調味液が収納され、食材収納部に調理用に断裁した食材が収納さていると共に、食材収納部の、調味液収納部と接触しないいずれかの辺に、間隙を維持した少なくとも2本の融着線が設けられ、該複数本の融着線の相互に離れ、且つ第1の弱融着線と接触しない端部に、それぞれ開口部を有し、好ましくは複数本の融着線の中で、最内部に位置する融着線の内方に、第2の弱融着線が設けられ、第1の弱融着線の剥離強度が、最内部に位置する融着線の内方に設けた第2の弱融着線の剥離強度と同等以上である。【選択図】 図2
