BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice ball packaging sheet in which a sheet-shaped food product such as seaweed is sandwiched between a plurality of films, and a packaged rice ball packaged with the packaging sheet.

[0002]

2. Description of the Related Art As such a wrapping sheet, a rectangular wrapping sheet (7) shown in FIGS. 4 and 5 has been previously proposed (Jitsuko 63-40152). The packaging sheet (7) has a sheet-shaped food product (8) sandwiched between two films, an outer film (1) and an inner film (2), and the outer film (1) is placed at the center in the width direction. A single perforation (91) is provided over the entire length in the longitudinal direction, and as the inner film (2), two film pieces (21) and (21) are formed on the opposite sides at approximately the center in the width direction of the packaging sheet. The outer film (1) and the inner film (2) are heat-welded on both side edges in the longitudinal direction.

As shown in FIG. 5, the packaging sheet (7) is provided with a triangular rice ball rice in the center of the inner surface of the sheet in the longitudinal direction.
Place one side of (4) and cover the triangular rice ball rice (4) with sheets.

The overlapping ears (71) (71) of the sheet are folded back to the back surface of the triangular rice ball rice (4), and as shown in FIG. 7, a seal piece (70) is provided between the folded back ears (71) (71). Stop with.

Since the inner film (2) is interposed between the rice ball rice (4) and the sheet food (3), the sheet food (8) does not contact the rice ball (4) and the rice ball The moisture of the sheet-like food is prevented from being damp.

When eating rice ball (4), the seal piece (7
0) is peeled off and the end portion (13) of the outer film (1) is pulled outward as indicated by an arrow. Since the outer film (1) is provided with perforations (91) at the center thereof, the outer film (1) is separated from the perforations to the left and right.

When the outer film (1) is divided into left and right parts, each film piece (21) (21) of the inner film (2) joined to the outer film (1) is separated into the outer film (1). The sheet-like food (8) and rice ball rice pulled by both film pieces of
Slide out between (4) and away from the rice ball (4),
This means that the sheet-shaped food product (8) directly covers the rice ball rice (4).

[0008]

[Problems to be solved by the invention] However, the rice ball wrapped with the above-mentioned packaging film must first peel off the seal piece (70). I cannot pull out the film properly.

Further, at the top of the triangular rice ball where the perforations (91) of the outer film (1) are located, the films are piled up in multiple layers and the rice balls are tightened, and the pull-out resistance of the film increases and the smooth pull-out occurs. However, the rice balls may be cracked at the center due to excessive force.

In particular, a rice ball with an ingredient such as umeboshi in the center is easily cracked at the center, so most of the rice ball will be cracked when the film is pulled out. or,
Even if the film is not cracked at the center of the rice ball, when the film is pulled outward as described above, the film has a circular arc shape as shown by an arrow A in FIG. There is a problem that a force acts on the film, and at that time, the bottom end of the rice ball is caught by the film and cracked.

Further, there is a problem that outside air penetrates through the perforations (91) of the outer film (1) to moisten the sheet food. As described above, the conventional packaging film has many problems and has not been put into practical use. The present invention clarifies a packaging film that can solve the above problems all at once and a rice ball packaged with the packaging film.

In the packaging sheet of the present invention, an intermediate film (3) is provided between the outer film (1) and the inner film (2), and the intermediate film (3) and the inner film (2) are provided. A rice ball packaging sheet in which a sheet-shaped food product (8) is sandwiched between the intermediate film (3) and the inner film (2) are rectangular film pieces (31) (31), (21) (21), respectively. The outer film (1) is provided with two perforations (91) (91) along the entire length in the longitudinal direction of the packaging sheet so that the outer film (1) is perforated (91). ) (91) is formed with a strip-shaped portion (9) for separation located substantially in the center in the width direction of the packaging sheet, and the outer peripheral portion of the film excluding both ends of the strip-shaped portion is heat-welded in three layers. There is.

In the rice ball wrapped with the above-mentioned packaging sheet, the intermediate film (3) and the inner film (2) are rectangular film pieces (31), (31), (21) and (21), respectively, in the width direction of the packaging sheet. The outer film (1) is made to face each other at substantially the center of the packaging sheet, and the outer film (1) has two perforations (91) (91) over the entire length in the longitudinal direction of the packaging sheet.
The perimeter of the film is formed between the perforations (91) and (91) by forming a strip-shaped portion (9) for separating at a substantially central portion in the width direction of the packaging sheet. The three parts are heat-sealed in a stacked manner, and the bottom of the triangular rice ball rice (4) faces the width direction of the film on the approximately central portion in the longitudinal direction of the inner film (2), and the outer film cutting strip-shaped part. (9) is wrapped from the top of the triangular rice ball (4) toward the center of the opposite side, and the four corner ears (71) of the packaging sheet are folded back on top of the back of the rice ball and folded back ( 71) is the outer film (1)
It is joined to the outside of the separating strip (9).

[0014]

[Operation and effect] Since the perforation (91) of the outer film (1) is closed from the inside by the intermediate film (3),
Outside air is prevented from entering the film through the intermittent slits of (91), and it is possible to prevent the sheet-shaped food from being humidified.

Further, when eating the packaging rice ball, it is not necessary to peel off the seal piece (70) joining the folded back ears (71) of the packaging sheet (7) as in the conventional case, and the next opening operation is smooth. Can be done
