PROBLEM TO BE SOLVED: To provide a wrapped rice lump, and a method for unwrapping the wrapped rice lump that can be unwrapped by a simpler method.SOLUTION: The wrapped rice lump is obtained by wrapping a rice lump 60 in a wrapping sheet 12. The wrapping sheet 12 is formed by holding sheet-like food 50 between a rectangular outer film 20 and an inner film 40 arranged on the rear face side of the outer film 20 in a deployed state. The outer film 20 has, at substantially the center in a width direction and a longitudinal direction, a split portion (24) with slits 21 longitudinally formed at predetermined spaces only in the substantially same length as the width of the rice lump 60. The inner film 40 is formed by overlapping a pair of inner film pieces 41 and 41 substantially at the center part in the width direction of the outer film 20, and welded 18 to the outer film 20 at the peripheral edge of the sheet-like food 50. The rice lump 60 is placed on the inner film 40 of the wrapping sheet 12 so that the split portion 24 of the outer film 20 faces the width of the rice lump 60 to wrap the rice lump 60 in the wrapping sheet 12, and the end of the wrapping sheet 12 is sealed with a fixing means 16.COPYRIGHT: (C)2013,JPO&INPIT【課題】より簡単な方法で飯塊の包装を解くことのできる包装飯塊及びその包装を解く方法を明らかにする。【解決手段】飯塊60を包装シート12で包んでなる包装飯塊であって、包装シート12は展開状態にて、長方形の外フィルム20と該外フィルム20の裏面側に配備された内フィルム40との間にシート状食品50を挟んで構成され、外フィルム20は、幅方向且つ長手方向の略中央に、長手方向に飯塊60の幅と略同じ長さにのみ所定間隔の切込み21を形成してなる裂け部(24)を有し、内フィルム40は、一対の内フィルム片41,41を外フィルム20の幅方向の略中央部で重ね合わせ、シート状食品50の周縁にて外フィルム20と溶着18して構成され、前記包装シート12の内フィルム40上に、外フィルム20の裂け部24が飯塊60の幅と対向するよう飯塊60を載せて、包装シート12にて飯塊60を包み、包装シート12の端部を止着手段16によって封止してなる。【選択図】図7
