PROBLEM TO BE SOLVED: To provide a package with a zipper which has an opening shape-keeping function capable of easily and reliably performing the take-out operation of a content, and easily performing the unsealing operation of the zipper. SOLUTION: The package has a zipper capable of opening/closing the opening part. By forming a projecting surface having an outwardly projecting shape on the upper scout part of the zipper, a part of the projecting surface of the upper scout part is deformed in a substantially flat shape when unsealing the package, and maintains the opening shape of the opening part. In addition, by forming a projecting part having an inwardly projecting shape on a film above the zipper, the films above the zipper keeps a space in between. COPYRIGHT: (C)2008,JPO&INPIT
