<p>PROBLEM TO BE SOLVED: To provide a packaging container for a microwave oven, usable as a packaging container for contents including a liquid, which are stored in a packaging bag and which are heated by a microwave oven, capable of releasing steam without causing the bag to burst due to steam to be generated by heating and without allowing the liquid to leak from a steam release part and the like, and further capable of being easily handled with bare hands after heating. SOLUTION: The packaging container for heating by a microwave oven is composed of a bag and an outer case for storing the bag. The bag uses a composite film, of which at least one of the surfaces is formed out of a heat- sealing layer, and a lower member, in which a heat-sealing face is used as an upper face, and an upper member, on which a wing part is formed by sealing heat-sealing faces and in which the heat-sealing face is used as a lower face, are superposed on each other to heat-seal the circumferential parts of the lower and upper members, thereby forming the bag. The outer case storing the bag has a structure of capable of drawing the wing part outwardly and holding the top end of the wing part upwardly in heating. Further, the packaging container for the microwave oven includes a steam releasing means provided at the wing part.</p> |
