<P>PROBLEM TO BE SOLVED: To provide a packaged Sushi provided with an unsealing mechanism and easily openable through such a simple operation as to only pull upper surfaces of the package film of the packaged Sushi in directions opposite to each other. <P>SOLUTION: The packaged Sushi 1 is obtained through packaging a Sushi 2 with a transparent package film 3. The packaged Sushi is provided with a film unsealing mechanism 4 structured as follows: forming perforations 5 on the package film 3 at a part corresponding to the upper part of the Sushi 2; placing a belt-shaped cover film 6 at the package film 3 inside the perforations so that the perforations 5 are positioned at almost the longitudinal center part of the film; sealing one side edge in a longitudinal direction of the belt-shaped cover film 6 so as not to cover the perforations 5 to form a sealing part 7. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
