<P>PROBLEM TO BE SOLVED: To provide a packaging bag suitable for shaking out an appropriate amount of the content (mainly, a granular material or a powdered material). <P>SOLUTION: Pleats are formed so that the pleats are projected outward on at least one of surface and back surface films, at positions close to the center from the upper end opening part, from one side part to the other side part of the packaging bag. When these pleats are extended, expansions seen from the outside and depressions in the inner part are formed. When the packaging bag is inclined, by making the face where the pleats are formed downward and making the opening part downward, as the content is collected in the depression, the appropriate amount of the content can be dropped and taken out by shaking the packaging bag upward and downward while observed by the eyes through the opening part if necessary. <P>COPYRIGHT: (C)2013,JPO&INPIT |
