<P>PROBLEM TO BE SOLVED: To provide a wrapping paper box in which water vapor does not go out and the box does not get into contact with any part of a microwave oven during rotation when the box is heated in the microwave oven even if the box has a little larger size. <P>SOLUTION: The wrapping box has an opening part 16 on the upper side of which an insertion panel 17 to be inserted in the inner surface of an upper panel 11 is connectively mounted, and an opening 24 is formed in the insertion panel 17. When the opening part is opened by pulling the insertion panel from the inner surface of the upper panel, the water vapor generated by heating by the microwave oven can go out since the opening is formed in the insertion panel. A protrusion made by a pair of cuts is mounted in a margin on the end margin side of the opening 24, and a slit for the protrusion of the insertion panel to be inserted through for stopping is formed in the vicinity of the end margin of the upper panel 11. <P>COPYRIGHT: (C)2007,JPO&INPIT |
