PROBLEM TO BE SOLVED: To protect a sheet-like laver and a rice ball from external factors such as an external pressure during handling from manufacturing of a package, to eating the rice ball through the distribution process to selling, and an unsealing operation of a bag when the rice ball is eaten while the amount of use of a packaging material is suppressed.SOLUTION: A lateral direction sealing part 24 formed by heat welding respective end edge parts of a sheet-like bag body 18 overlapped above the rice ball 22 in the bag 20 is extended over both left and right end edges of the bag 20. Longitudinal direction sealing parts 26 and 26 formed by heat welding the sheet-like bag body 18 overlapped on both left and right sides placing the rice ball 22 between them in the bag 20 are extended in the longitudinal direction so as to intersect the lateral direction sealing part 24. Turning-in parts 34 turned-in upward are formed on both left and right end parts being a bottom face of the bag 20. A gas is sealed into a first sealing room which is partitioned in the sheet-like bag body 18 and in which the sheet-like laver 16 is stored under a sealed condition.COPYRIGHT: (C)2011,JPO&INPIT【課題】包装材の使用量を抑えたもとで、包装体の製造から販売までの流通過程を経ておにぎりを食するまでにおける取り扱い時の外圧や、おにぎりを食する際における袋の開封動作等の外的要因からシート状の海苔とおにぎりを保護する。【解決手段】袋20におけるおにぎり22の上方で重合するシート状袋体18の各端縁部を熱溶着して形成された横方向シール部24が、袋20の左右両端縁間に亘って延在する。袋20におけるおにぎり22を挟む左右両側で重合するシート状袋体18を熱溶着して形成された縦方向シール部26,26は、横方向シール部24と交差するよう縦方向に延在する。袋20の底面となる左右両端部に、上方に向けて折り込まれた折込み部34が形成される。シート状袋体18の内部に画成され、シート状の海苔16が密封状態で収容される第1密封室に気体が封入される。【選択図】図1
