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. A front side film that covers the front side film with the film pieces 61 and 62 and overlaps the back side film provided with an overlapping part between the film pieces at a position located in the dividing means of the front side film, and excludes the overlapping part between the film pieces of the back side film. A sheet body 50 provided with a bag portion for containing a sheet-like food N such as seaweed by joining both sides of the film and the backside film by heat sealing means is widely used (Patent Literature is known as a known example) 1).

  In this case, it is indispensable that the packaging material is provided with a pattern or display, but it is general that the pattern or display is applied to the sheet body by printing.

  On the other hand, a technique for enhancing barrier properties, design properties, and texture by laminating non-plastic sheet bodies such as paper, nonwoven fabric, and metal foil on a plastic film is well known. Then, applying this well-known technique also to the packaging film of a rice ball is proposed (patent document 2 as a well-known example).

In particular, as shown in FIG. 7, the sheet body 50 is provided with a splitting means 53 extending over the entire length and the rice ball R packaged therein, and the sheet body is formed into a rectangular parallelepiped with the rice ball placed on the upper side. As a result, at least three 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. Assuming a molded cooked rice food with packaging, the surface area of the packaging body for rice balls is larger than that of the triangular packaging body disclosed in Patent Document 1, so by laminating paper or nonwoven fabric on the sheet body The overall design and texture are remarkably increased, and it is an optimal means for producing a high-class feeling of food and is highly useful.

  However, when the sheet body as shown in FIG. 8 provided with a bag part for containing sheet-like food inside by joining both sides of the front side film and the back side film by heat sealing means, If different materials made of non-plastic are laminated on the film, the sheet will bend and curl due to the difference in shrinkage between the film part and the different material part due to heating during heat sealing, which will adversely affect the packaging work by the automatic packaging machine. Caused a problem.

The present invention has been created for the purpose of providing a sheet body that solves the above-mentioned problems, and has a plastic front-side film having a dividing means for dividing it into two in the short direction. A pair of divided film pieces covers all or part of the front side film, and a plastic back side film provided with an overlapping portion between the film pieces is overlapped at a position located in the dividing means of the front side film, and the film piece of the back side film In a sheet body for packaging shaped cooked rice food that constitutes a bag part for containing sheet-like food inside by joining both sides of the front side film and back side film excluding the overlapping part with each other by heat sealing means , the heat sealing means paper or a region inside the region in which resides nonwoven fabric or a metal foil made of the sheet material of the front film Characterized in that the layers.

According to the present invention, the sheet material made of paper, non-woven fabric or metal foil is laminated on the inner area of the front side film and the back side film while avoiding the area where the heat sealing means exists. This produces an effect of preventing the sheet body from being bent.

    FIG.1 and FIG.2 is a figure which shows the structure of the sheet | seat body 1 of this invention. The sheet body 1 has a structure in which a plastic front film 10 and back films 13 and 14 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 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. In addition, here, in order to facilitate tearing at the start of lifting of the dividing means (cut tape), a pair of cuts 6A and 6A are provided on the left and right of the starting position of the dividing means at one end of the front film.

  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 bag parts for accommodating the sheet-like food N inside by providing the heat seal part S1 on the periphery except for the overlapping part of the film pieces of the back side film. Configure. In this embodiment, nori is assumed as the sheet-like food N, but the sheet-like food is not limited to nori.

  Reference symbol P in the drawing is a sheet material laminated on the surface of the front film 10. This sheet material P is laminated in order to enhance the design and texture of the packaging material, and paper, non-woven fabric, metal foil and the like are assumed. The sheet material P is laminated in a region inside the regions F and F where the heat sealing means exists, and this constitutes a characteristic part of the present invention.

  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.
