<P>PROBLEM TO BE SOLVED: To improve the shape of a packaging bag for mixing a powder and a liquid, and of compartments, partition seals, or the like of the bag as well, to provide the packaging bag useful for mixing the powder and liquid that maintains partitions for each compartment in a distribution process but enables easy selective peeling of the partition seals without unsealing peripheral seals to allow the same amount of the powder and the liquid as a content of the bag to be mixed together uniformly when the bag is used. <P>SOLUTION: The packaging bag comprises the compartment which contains the powder and has the outer peripheral end whose periphery is sealed by heat fusion welding, the compartment which contains the liquid and has the peripheral edge sealed by heat fusion welding, and the partition seal which partitions the two compartments. The inner dimension, which is parallel with the partition seal, of either of the two compartments is shorter than the inner dimension, which is perpendicular to the partition seal, of either of the two compartments, and the powder and the liquid are mixed together when the partition seal is peeled off. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
