<P>PROBLEM TO BE SOLVED: To provide a packaging container with a small bag attached to the inner surface of a container lid, which container can be produced stably and can solve the problem of a sharp temperature increase and damage to a packaging material due to the temperature increase when the container is heated in a microwave oven. <P>SOLUTION: The packaging container 1 is composed of a container body 21 having an opening, a lid 22 which covers the opening of the container body 21, and the bag 3 which is heat-welded removably to the inner surface of the lid 22. At least a part of the inner surface of the lid 22 is made of a first sealant layer 221 which can be heat-welded removably to the bag 3. The bag 3 is formed of (A) a sheet which has one surface made of a high melting-point sealant layer 311 that can be heat-sealed removably to the inner surface of the lid 22, and the other surface made of a low melting-point sealant layer 313 that has a melting point 30°C or more lower than that of the high melting-point sealant layer 311, and (B) a sheet which has one surface made of a second sealant layer 321 that can be heat-welded to the low melting-point sealant layer 313. <P>COPYRIGHT: (C)2007,JPO&INPIT |
