  • FIG. 19 shows an example, in which the covering member 28 is integrated with the side edges 14 a and 14 c;
  • FIG. 20 shows an example, in which the covering member 28 is integrated with the side edges 14 a, 14 b and 14 c.
  • the covering member 28 is fixed to the one part of the outer film 14 , which is divided into two by the dividable section 12 , by, for example, heat seal.
  • the covering member 28 and the outer film 14 may be separately formed, and the covering member may be heat-sealed to a proper position of the outer film 14 ; the covering member 28 and the outer film 14 may be integrally formed.
  • the cone-shaped sushi-rice or ordinary rice is shown by dotted lines.
  • the fixing tape 15 is taped at the end of the side edge 12 a of the dividable section 12 so as to prevent the part of the outer film 14 from being divided, but the end of the dividable section 12 may be heat-sealed to the corresponding inner film 16 a (not shown).
  • the both side edges of the dividable section 12 are capable of dividing the outer film.
  • the dividable section 12 divides the outer film 14
  • the one side part of the wrapper which includes the one part of the outer film still connected to the dividable section 12 and the inner film 16 a connected to the one part thereof, can be separated from the other side part of the rice wrapper, which includes the other part of the outer film divided and the inner film 16 b connected to the other part thereof, in one action, by pulling the dividable section 12 .
  • the end of the dividable section 12 may be fixed to the covering member 28 (not shown).
  • the both side edges of the dividable section 12 are capable of dividing the outer film.
  • an incision (not shown), through which the dividable section 12 can pass, may be formed in the covering member 28 so as to smoothly divide by the dividable section 12 .
  • FIG. 21 shows a position of a fixing tape 30 for fixing the covering member 28 to the outer film 14 .
  • the fixing tape 30 is fixed to the part of the outer film 14 , which has been divided from the other part of the outer film 14 by the dividable section 12 and which is connected to the dividable section 12 (i.e., the part of the outer film located nearer a top part B shown in FIG. 21 ).
  • the end of the dividable section 12 is pulled in a direction D shown in FIG. 21 , an incision (not shown) may be previously formed in a part of the covering member 28 , as described above, so as to divide the outer film by the dividable section 12 .
  • FIG. 22 shows another embodiment.
  • a cutting direction guide 12 c is provided to an intermediate part of the side edge 12 a of the dividable section 12 , and a cutting direction of the outer film 14 , which is cut by the dividable section 12 , is diagonally directed as shown by a dotted line; note that, the outer film may be cut until reaching the sealed part (hatched part), in which the outer film 14 and the inner film 16 a are sealed, and the outer film 14 may be uncut in the sealed part (in this case, the outer film is composed of a material which can be continuously cut in a changed direction when the cutting direction is changed).
  • the one side part of the wrapper can be separated from the other side part thereof, in one action, by pulling the dividable section 12 .
  • cutting lines of the dividable section 12 which are formed for cutting the outer film in the directions of the side edges 12 b and 12 c, may be previously formed.
  • the fixing tape 15 which is taped on the end part of the side edge 12 a of the dividable section 12 and the part of the outer film 14 adjacent thereto as shown in FIG. 1 , can be omitted, so the sealed part (adhered part), in which the outer film 14 and the inner film 16 are sealed, may be act as the undividable section.
  • fixing means e.g., fixing tape 17 for fixing the outer wrapping part 24 to the inner wrapping part 22 is not provided on the cutting line.
  • FIG. 23 shows modification of the embodiment shown in FIG. 22 .
  • the side edges of the dividable section 12 are two crossed lines.
  • the cutting direction of the dividable section 12 is changed from the cross point of the lines, so that the outer film is cut in the diagonal directions shown by dotted lines ( 12 d and 12 e ).
  • the outer film 14 is not cut in the sealed part (in this case, the outer film is composed of a material which can be continuously cut in the changed direction when the cutting direction is changed to the directions 12 d and 12 e ).
  • FIG. 24 shows further embodiment of the wrapper 10 .
  • the outer film 14 is constituted by two film pieces 14 a and 14 b, whose center parts are overlapped each other.
