<P>PROBLEM TO BE SOLVED: To provide a packaging box for a sealed packaging bag for microwave heating, by which the box interior, an unsealed mouth, or the microwave interior is prevented from soil caused by steam released or scattered from the packaging bag, even if the sealed packaging bag with an easy-peeling function and containing a sealed food or the like for microwave heating is heated in a microwave oven to release steam. <P>SOLUTION: The flat sealed packaging bag A for microwave heating is housed and packaged in the box B, whose unsealing lid board C is partly opened along an unsealing cut line, and the packaging bag A stored in the box B is heated in the microwave oven. At this time, steam (a) jetted from an opening of a vent-opening sealing portion 16 of the sealed packaging bag A heated in the box B by the microwave oven, is applied to the partly opened unsealing lid board C of the box B. This prevents the steam (a) from being directly released or scattered from the vent-opening sealing portion 16 of the packaging bag A to the outside of the box B. <P>COPYRIGHT: (C)2008,JPO&INPIT |
