Abstract

<P>PROBLEM TO BE SOLVED: To prevent a sheet-shaped food in a sheet body used for a formed rice food with a wrapper from being dampened. <P>SOLUTION: The sheet body 1 for wrapping a formed rice food is formed by superposing a rear side film covering part of or the whole of a front side film with a pair of film pieces 12, 14 split into two in the short side direction and having a film-piece/film-piece overlapping part at the position corresponding to a splitting means provided of the front side film on the front side film 10 provided with the splitting means for splitting in the short side direction and bonding the front side film excluding the film-piece/film-piece overlapping part of the rear side film and both sides of the rear side film with one another to form a bag part for accommodating the sheet-shaped food N. In the film-piece/film-piece overlapping part of the rear film, strips 15, 17 are opened at the one ends of the paired rear film pieces of the rear film to form gaps 16, 18, into which the one ends of the pack film pieces are inserted. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a sheet body for packaging shaped cooked rice food such as rice balls.

  As a packaging material made of a plastic film for packaging rice balls, a pair of the front side film 60 divided into two in the lateral direction is divided into a rectangular front film 60 having a dividing means 53 for dividing into two in the lateral direction as shown in FIG. The front side film is formed by covering the front side film with the film pieces 61 and 62 and overlapping the back side film provided with the overlapping part of the film side at the position located in the dividing means of the front side film and excluding the overlapping part between the film pieces of the back side film. A sheet body 50 having a bag portion for containing sheet-like food N such as seaweed by joining both sides of the film and the back film is widely used (Patent Document 1 as a known example).

On the other hand, as shown in FIG. 7, the sheet body 50 is provided with a dividing means 53 extending over the entire length, and the rice ball R is wrapped in the sheet body. As a result, at least three or more of the inner wall surfaces of the package are brought into close contact with the rice ball, and the flanges 52, 52 are formed on the pair of side walls 51, 51 which the package is opposed to each other, and the bent line 52A projects inwardly. Molded cooked rice food with packaging has been proposed.

  In the above-mentioned shaped cooked cooked rice food, the package has an effect of preventing falling off by being in close contact with the rice ball R. On the other hand, the sheet constituting the package has a sheet-like food N such as laver inside. Since it has the bag part for accommodating, a bad effect also arises by contacting closely. That is, when moisture (steam) transpiration from the rice ball R enters the bag portion from the overlapping portion of the film pieces 61, 62 of the sheet body 50, wets the sheet-like food N accommodated therein, and this is laver. Had the problem of damaging the crisp texture peculiar to laver.

  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. Cover the whole or part of the front side film with the film piece and overlap the back side film provided with the overlapping part of the film side at the position located in the dividing means of the front side film, excluding the overlapping part of the film piece of the back side film In the sheet body for wrapping the shaped cooked rice food that constitutes the bag portion for containing the sheet-like food inside by joining both sides of the front side film and the back side film, the overlap of the pair of film pieces of the back side film At each location, a strip is attached to each end of the pair of film pieces of the back film so that one end is open and constitutes a gap, Wherein the enhanced air-tightness of the bag part in each other's gaps by inserting each other's films one end.

  According to the present invention, the belt-like piece is fixed to each of the pair of film piece ends of the backside film so that one end is opened to form a gap, and the film piece ends are inserted into the gap (FIG. 1, 2), the other film piece end is alternately sandwiched between one film piece end and the strip-like piece, the airtightness of the overlapping part of the film pieces is improved, and moisture is transferred from the overlapping part of the film pieces into the bag part. Intrusion is blocked and the sheet-like food is prevented from getting wet.

    1 and 2 are views showing the configuration of the sheet body 1 of the present invention. This sheet body 1 has a structure in which the front film 10 and the back films 13 and 14 are polymerized so as to form a bag portion for containing a sheet-like food therein. 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 this embodiment, two narrow cut tapes T1 and T2 fixed to the front film 10 are used as the dividing means. However, as long as the front film 1 can be stripped by being pulled up, Of course, the dividing means is not limited to a cut tape. Further, in order to facilitate tearing at the start of lifting of the dividing means (cut tape), a means such as providing a pair of cuts 6A and 6A on the left and right of the starting position of the dividing means at one end of the front side film may be arranged. Good.

  The back film is a film that contacts 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 short direction to cover the front film 10, and these film pieces are means for dividing the front film. An overlapping portion is formed that partially overlaps at a position located in the area.

  The front side film 10 and the back side films 13 and 14 are provided with a welded part S1 on the periphery excluding the overlapping part of the film pieces of the back side film and polymerized to form a bag part for containing the sheet-like food N therein. Constitute. In this embodiment, nori is assumed as the sheet-like food N.

  At the overlapping position of the pair of film pieces 13 and 14 of the back film, the strip piece 15 is fixed so that one end is opened at one film piece 14 end to form a gap 16 and the other film piece 13 end is formed. One end of the belt piece 17 is fixed so as to form a gap 18, and the end of the film piece 13 is inserted into the gap 16 and the end of the film piece 14 is inserted into the gap 18 (see FIG. 2). By doing so, it is possible to obtain an effect of preventing moisture generated from the rice balls R during packaging from entering the overlapping portions of the sheet bodies and moistening the sheet-like food N. In this embodiment, the strips 15 and 17 are fixed to the surfaces of the pair of film pieces 13 and 14 in consideration of the production efficiency, but the fixing surfaces are not limited to these.

  FIG. 3 to FIG. 6 are views showing a production process of an example of a packaged cooked cooked rice food using the sheet body of the present invention. Here, a triangular rice ball is illustrated as the cooked 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 rear 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 with the front is the front of the rice ball. 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. In addition to heat sealing, the regions 3 and 3 are also heat sealed (see FIG. 5).

  Next, while folding the side flanges D and D inward so that the crease 5A protrudes toward the inside of the package, the front part A and the back part C are overlapped at the opening (see FIG. 6) and further closed ( The series of packaging is complete.
