  When opening the shaped cooked cooked rice food, the end of the cut tape 53 provided on the front film 60 is picked and pulled to the other end of the front film along the outer periphery in the longitudinal direction (longitudinal direction of the sheet) of the package. As a result, a strip-shaped notch is generated in the front film, and the front film is divided into two in the lateral direction. In this case, since the back side film is composed of film pieces 61 and 62 divided into two in the short direction, the sheet body 50 is divided into two in the short direction. By pulling left and right, nori N The sheet body should be detached from the onigiri in the state of being wound.

  However, as described above, the short side edges 50A and 50A of the sheet body 50 facing each other at the opening of the package are fused at the heat seal location HS. FIG. 11B is a view showing an end surface of the package body before fusion of the heat seal spot HS in this case, but the films 60, 61, 62 constituting the sheet body 50 are formed into a bag shape by fusion. Since it is joined, it must have heat sealability on the back side. That is, when both ends 50A, 50A on the short side of the sheet body 50 are fused at the heat seal location HS, the films are fused as indicated by (XX) in the above figure. The film pieces 61 and 62 of the back side film of the heel that is originally divided into two are also fused. Therefore, even if the front side film is divided into two parts by the cut tape, the back side film remains bonded in the vicinity of both ends 50A and 50A on the short side of the sheet body 50, and it is necessary to work to peel off this part one by one when opening. The problem of poor openability remained.

  The present invention was created for the purpose of providing a sheet body that solves the above-mentioned problems, and is a pair of a front-side film having a dividing means for dividing it into two in the short direction and divided into two in the short direction. A bag for covering the whole or a part of the front side film with the film piece and overlapping the back side film provided with the overlapping part of the film pieces at the position located in the dividing means of the front side film and storing the sheet-like food inside In a sheet body for wrapping molded cooked rice food in which a front side film and a back side film are fused by heat sealing so as to constitute a part, one or both of the film pieces overlap at the overlapping part of a pair of film pieces of the back side film A strip-shaped tape with a non-heat-sealing surface on the front side and a non-heat-sealing surface on the back side of the front film By laminating over direction, characterized in that the cutting means for bisecting the front side film in lateral direction.

  In addition, the molded cooked rice food with packaging of the present invention uses the sheet body, bends the sheet body in a state of placing the molded cooked rice food on the sheet body in a U shape so that both ends on the short side face each other, Bend the both ends of the long side to the side wall side of the shaped cooked rice food and join them together to form a bag into a rectangular parallelepiped that opens upward, and then melt the two ends on the short side of the sheet facing each other at the opening by heat sealing. It is characterized by sealing by wearing.

  According to the sheet body of the present invention, at the overlapping portion of the pair of film pieces of the back film, the surface in the overlapping direction of one or both film pieces is set as a non-heat seal surface, and the front film is divided into two in the short direction. Since the surface of the strip-shaped tape for making it is a non-heat-sealing surface, the bag is made so that both ends on the short side of the sheet body face each other at the opening, and when the two ends are fused by heat sealing, The portion where the non-heat seal surface abuts has an effect of not being fused. Therefore, it is prevented that the film pieces divided into two parts of the back side film as in the prior art are joined in the vicinity of both ends on the short side of the sheet body, and if the front side film is divided into two parts using a strip-shaped tape as a cut tape Immediately after the sheet body is divided into two parts, it is possible to easily open the sheet.

    1 and 2 are views showing the configuration of the sheet body 1 of the present invention. The sheet body 1 has a structure in which a front film 10 and back films 13 and 14 having a back surface as a heat seal layer are polymerized so as to form a bag portion for containing a sheet-like food. The front-side film 10 has a rectangular shape, and has a dividing means by strip-shaped cutting for dividing into two in the short direction. In the present invention, a strip-shaped tape 11 is laminated on the back surface of the front film 10 as a dividing means, and the surface of the tape 11 is a non-heat seal surface. In this embodiment, the band-shaped tape 11 is made wider than the conventional cut tape and is made of a material having a suitable waist, thereby facilitating the search for the tape end at the fingertip when tearing. Further, in order to facilitate tearing at the start of lifting of the dividing means (band-shaped tape), a pair of cuts 12 and 12 are provided on the left and right of the starting position of the dividing means at one end of the front film.

  The back side film is a film on the side in contact with the rice ball R at the time of packaging, and is composed of a pair of film pieces 13 and 14 that are divided into two in the lateral direction so as to cover all or part of the front side film 10. An overlapping portion is formed that partially overlaps at a position located in the front-side film dividing means.

  The front-side film 10 and the back-side films 13 and 14 are provided with a heat-sealed portion S1 at the periphery excluding the overlapping portion between the film pieces of the back-side film, and are fused and polymerized to accommodate the sheet-like food N therein. The bag part is configured. In this embodiment, nori is assumed as the sheet-like food N.

  In the overlapping part of the pair of film pieces 13 and 14 of the back film, the surface in the overlapping direction of one or both film pieces is a non-heat seal surface. In this embodiment, by laminating a strip-shaped tape 15 whose surface is a non-heat-sealed surface on the back surface of the film piece 14 located on the outer side of the overlap along the overlapping position with the other film piece 13. Although it is said means, as shown in FIG. 3, you may process the surface of the overlapping direction of the applicable part in any one of the film pieces 13 and 14 as a non-heat-sealing surface.

  FIG. 4 to FIG. 8 are diagrams showing a manufacturing process of an example of a shaped cooked cooked rice food using the sheet body of the present invention, and here, a triangular rice ball is illustrated as the shaped cooked rice food. In the figure, reference numeral 1 denotes a sheet body, and the regions constituting the front portion A, bottom ridge portion B, and back portion C of the package body with the folds 2B and 2B as the boundary in a state where the rice ball R is in contact therewith Then, the regions 3 and 3 constituting the side flange portions D and D of the package are folded to the rice ball side with the folds 2A and 2A as a boundary. At that time, the regions 3 and 3 constituting the side flange portions D and D of the package and the region 4 sandwiched between the folds 2A are folded at the folds 2B, 2B and 2C and 2C, and the regions 3 and 3 Polymerized on the back side.

  Through the above process, a packaging body made of a rectangular parallelepiped opening upward is obtained, and the regions 3 and 3 constituting the side flange portions D and D and the region 4 that is folded and polymerized on the back surface thereof are simultaneously formed in the heat seal portion S2. While being fused, the regions 3 and 3 are also heat-sealed (see FIG. 6).

  Next, the front side A and the back side C are brought close to each other at the opening while folding the side flanges D and D inward so that the fold 5A protrudes toward the inside of the package (see FIG. 7), and the sheet facing the opening. A series of packaging is completed by fusing and sealing the short sides of the body 1 at the heat-seal locations S (see FIG. 8).

  (A) of FIG. 11 is a figure which shows the end surface before the fusion | melting of the heat seal location S of the molded cooked rice food of this invention. As is apparent from this figure, the fusion location of each film indicated by (◯◯◯) is the back surface of the film piece 14 on the outer side of the overlap at the overlap location of the pair of film pieces 13 and 14 of the back film. Since it is interrupted by the non-heat-sealed surface of the surface of the strip-shaped tape 15 laminated on the surface and the non-heat-sealed surface of the surface of the strip-shaped tape 11 laminated on the back surface of the front film, it is illustrated as-(XXX)-, heat-sealed Even if the heat seal roller is brought into contact with the entire portion S, the blocking portion is not fused.
