  • the two inner films 16 are a wide film piece 16 a and a narrow film piece 16 b which is narrower than the wide film piece 16 a as shown in FIG. 1-5 .
  • the narrow film piece 16 b is placed on the long side 10 d side of the wrapper 10 , so that the divided films can be easily removed from the cooked rice, e.g., shaped rice, sushi rice, as described later.
  • any one of the film pieces may be located inside or outside. Further, one or both of the film pieces in the overlapped part may be further folded (not shown).
  • a corner of the food sheet 18 located close to the corner part A may be cut as shown in FIG. 1 .
  • the film pieces can be easily pulled out, without being engaged with the food sheet 18 , when the divided films are pulled out from the cooked rice, e.g., shaped rice, sushi rice, as described later.
  • the inner films 16 are the wide film piece 16 a and the narrow film piece 16 b, so that an upper part of the outer film 14 (a part including the corner part B, see FIG. 6 ) and the wide film piece 16 a of the inner films 16 , which is fixed to the upper part, can be upwardly pulled out in the state where the food sheet 18 is left on the sushi rice 20 , when the outer film 14 is divided into two by the separable part 12 .
  • the wide film piece 16 a of the inner films 16 is wide, a resistance between the film piece and the sushi rice 20 is increased and the film piece is hardly pulled out, but the film piece is upwardly pulled out in an open space, so even if the food sheet 18 exists, the separable part 12 can be easily pulled out by pulling the separable part upward, without being interfered with the food sheet 18 .
  • the divided films can be further easily pulled out downward.
  • the wrapped body 26 is produced by rolling the wrapper 10 over the conical-shaped sushi rice 20 .
  • the wrapper 10 is previously formed into the deformed conical shape shown in FIG. 6 , then the sushi rice 20 , which has been formed into the conical shape, is dropped into the wrapper 10 , which has been formed into the deformed conical shape, to produce the wrapped body 26 .
  • the wrapped bodies can be automatically produced by continuously feeding the wrapper 10 , which have been formed into the deformed conical shape, to an automatic production apparatus (not shown) and sequentially dropping pieces of the sushi rice, which have been formed into the conical shape, into the wrappers 10 .
  • the wrappers 10 may be previously formed into the deformed conical shape by hands or an apparatus, it is preferable that the above described marks 31 , 32 a and 32 b are provided so as to accurately position each of the parts, so that the deformed conical shape can be accurately formed.
  • the wrapped body 26 is covered with a transparent covering member 28 so as to cover an exposed part of the sushi rice 20 (an opened bottom part of the conical shape).
  • the covering member 28 is provided to a part constituting a bottom side of the deformed conical part of the wrapper so that the opened bottom part of the deformed conical part can be covered.
  • FIG. 18 shows a position of a fixing seal 30 , which is used when the covering member 28 is fixed to the outer film 14 by the fixing seal 30 .
  • a third positioning mark 34 and a fourth positioning mark 35 which are used when the covering member 28 is bent to cover the opened bottom part of the deformed conical part and fixed to the outer film 14 , are respectively provided to the covering member 28 and the outer film 14 .
