<P>PROBLEM TO BE SOLVED: To provide a packaging bag which is fit for preserving food materials which are not desirable to be preserved in a mixed condition, readily mixes the food materials together at the time of heating and cooking, by breaking a partition between the food materials by increasing inner pressure of the packaging bag, can reduce the inner pressure of the packaging bag in order to prevent the packaging bag from an unexpected breakage due to steam generated in the bag during the heating and cooking, and is easily manufactured at a low cost. <P>SOLUTION: According to the structure of the packaging bag, a rear sealing portion is formed on a rear side of the bag so as to extend from an almost central portion of one edge sealing portion to an almost central portion of the other edge sealing portion as viewed in a plan, and a dividing sealing portion is set at a location that does not overlap the rear sealing portion in the plan view in order to divide the interior of the packaging bag into a plurality of storage sections. The sealing portions are implemented by heat sealing. The storage section with the rear sealing portion hermetically contains therein a dried food material, and at least one of the storage sections other than the storage section with the rear sealing portion hermetically contains therein a liquid food material. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
