<P>PROBLEM TO BE SOLVED: To provide a self-standing pouch which has its interior partitioned into two chambers, exerts good self-standing property, and prevents its content from spilling during cooking. <P>SOLUTION: According to the structure of the self-standing pouch, a gusset portion is formed at the lower part thereof, and a body portion is formed by heat-sealing both side edges of each of front and rear wall films at side seal portions. Part of the pouch is partitioned into the two chambers by a heat-seal portion which is formed of a pillar seal portion provided in parallel with the side seal portion or at an angle of 30° or less with respect to the side seal portion, and a dividing seal portion provided from the lower part of the pillar seal portion diagonally downward to the side seal portion. Wherein an intersection position between the partitioning seal portion and the side seal portion is located below a position at which the partitioning seal portion and the side seal portion intersect each other at right angle, and above a position at which a bottom film folded portion and the side seal portion intersect each other. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
