The present invention ensures the break for the inside and outside of the sheet material during the test diet, ease, and also to maintain the non-fracture due to transport load of the sheet material at the time of rice ball packaging, yet rice ball package that does not impair also the sealing property at the time of packaging I provide. A by two-fold the original Han packaging body 1 made was sealed holding the sheet-like food S by the sheet material 2 and 3 of the inside and outside double that is to be separated by the break line 4 and 5 the rice ball R and pinching, the packaging of rice ball R the periphery of the original anti-packaging body 1 is sealed welding 7. Break lines 4 and 5 which are formed inside and outside of the sheet material 2, 3 Yes formed by fusing the sealing structure is positioned along the central position along the folding direction in the clamshell raw packaging material 1 . In addition, the upper side edge of the package 1, it will form a notch 6 which is continuous to the break line 4 and 5. .BACKGROUND【課題】供食時の内外のシート材に対する破断の確実、容易性、また握り飯包装時におけるシート材の搬送負荷による非破断性を維持し、しかも包装時の密封性をも損なわない握り飯包装体を提供する。【解決手段】破断線4,5によって分離可能になっている内外二重のシート材2,3によってシート状食品Sを密封保持して成る包装体1の原反を二つ折りして握り飯Rを挟み込み、包装体1の原反の周縁を密封溶着7して握り飯Rを包装する。内外のシート材2,3に形成した破断線4,5は、溶断シール構造によって形成してあり、包装体1の原反を二つ折りしたときの折方向に沿った中央位置に沿って配置する。また、包装体1の上辺縁には、破断線4,5に連続するノッチ6を形成する。【選択図】図1
