DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onigiri packaging sheet in which a sheet-like food such as a sheet of laver is sandwiched between an inner film and an outer film, and a packaging rice ball packaged with the packaging sheet.

[0002]

2. Description of the Related Art The applicant has previously proposed a rectangular packaging sheet (7) shown in FIGS. 9 and 10 as such a packaging sheet (Japanese Utility Model Publication No. 7-51912). The packaging sheet is an outer film
An intermediate film (3) is provided between (1) and the inner film (2), and a sheet-like food (8) is sandwiched between the intermediate film (3) and the inner film (2). At the center in the width direction of the outer film (1), a cutting line (9) penetrating the front and back of the film along the longitudinal direction is intermittently provided. Intermediate film (3)
And the inner film (2) are rectangular film pieces (31) and (3), respectively.
1), (21), and (21) are formed by overlapping opposing sides at substantially the center in the width direction of the packaging sheet (7). Each film (1)
In (2) and (3), the outer peripheral portions except for the central portions at both ends are heat-welded in three layers.

As shown in FIG. 11, one side of a triangular onigiri rice (4) is placed on the inner side of the packaging sheet (7) at a substantially central portion in the longitudinal direction of the triangular onigiri rice (4). Put a sheet on. The overlapping ears (70) and (70) of the sheet are folded back on the back of the triangular rice ball (4), and both folded ears (70)
(70) is stopped by heat welding (73) or a sealing piece.

When eating rice ball rice (4), both ends (13) and (13) of the outer film (1) are indicated by arrows around the cutting line (9) of the outer film (1) of the wrapped rice ball. As described above, the outer film (1) is pulled right and left to divide the outer film (1) into two right and left sides from the cutting line (9). When the outer film (1) is divided into two parts, the inner film
Each of the film pieces (21) and (21) of (2) is also pulled together with the two film pieces of the outer film, and slides out from between the sheet-like food (8) and the onigiri rice (4) to produce the onigiri rice (4). ). As a result, the sheet food (8) is replaced with the rice ball (4)
Cover directly.

[0005] In the above-mentioned wrapped rice ball, an inner film (2) is interposed between the rice ball (4) and the sheet food (8), and the sheet food (8) comes into contact with the rice ball (4). The intermediate film (3) is interposed between the outer film (1) and the sheet-like food (8), and the outside air invades from the striated line (9) of the outer film (1). To prevent sheet-like food
(8) can be prevented from getting wet.

[0006]

The cutting line (9) of the outer film (1) of the packaging sheet (7) is provided over the entire length from the top to the center of the bottom of the rice ball, so carelessly. They may be torn, and the appearance of the cutting line (9) is noticeable during display. Further, the number of films used for the wrapping sheet increases, which increases the cost. The present invention is to clarify a packaging sheet capable of solving the above-mentioned problem and a rice ball wrapped with the packaging sheet.

[0007]

The wrapping sheet of the present invention is a rice ball wrapping sheet in which a sheet food (8) is sandwiched between an outer film (1) and an inner film (2). Is formed by laminating two rectangular film pieces (21) and (21) on opposite sides at substantially the center in the width direction of the packaging sheet, and the outer film (1) is apt to tear along the longitudinal direction. The film is provided with one or a plurality of cutting lines (9) penetrating the front and back of the film along the longitudinal direction only at substantially the center in the longitudinal direction and the width direction.

The rice balls wrapped in the above-mentioned wrapping sheet are prepared by placing a triangular onigiri rice at a substantially central portion of the wrapping sheet so that one side thereof is orthogonal to the longitudinal direction of the wrapping sheet. (21) The wrapped portion (20) of (21) is packaged so as to extend from the top of the triangular rice ball (4) to the center of the opposite side.

[0009]

[Function and effect] The cutting line (9) of the outer film (1) is applied only to the substantially central portion in the longitudinal direction of the film, and the rice ball (4) has one side in the longitudinal direction of the packaging sheet. Since the packaged rice balls are wrapped so as to be orthogonal to the longitudinal direction at the substantially central part of the rice balls, when the wrapped rice balls are displayed with the triangular face up and down, the cutting line (9) is almost hidden by the bottom of the rice balls. The cut line (9) does not impair the appearance of the wrapped rice ball.

[0010] The cutting line (9) is the same as the conventional film
If the wrapping rice balls are displayed so that the cutting line (9) is positioned on the bottom side of the rice balls, the cutting line will be shorter than the one that is applied over the entire length of (1). The ingress of outside air from line (9) is greatly reduced. For this reason, it is possible to omit the intermediate film for preventing the invasion of the outside air, or to use two film pieces as in the conventional intermediate film.
(31) Even if the inner ends of the (31) are not overlapped, one strip film having a width covering the cutting line (9) is sufficient. Therefore, the cost can be reduced by reducing the number of films. Of course, it is also possible to use an intermediate film composed of two film pieces (31) and (31) in the same manner as in the prior art.

[0011] When eating rice ball rice, the outer film around the cutting line (9) of the outer film (1) of the wrapped rice ball
Pull both ends (13) and (13) of (1) left and right. Outer film (1)
Is a directional film that is easily torn in the longitudinal direction, so that the striated line (9) extends and the outer film (1) is divided into two right and left parts.
When the outer film (1) is pulled left and right, the inner film
Each film piece (21) (21) of (2) is an outer film divided into two
It is pulled together with the two film pieces (11) and (11) of (1) and slides out from between the sheet-like food (8) and the rice ball (4) to separate from the rice ball (4). This allows for sheet food
(8) directly covers the rice ball (4).

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The outer film (1) has a length of about 220 mm and a width of about 1 mm.
This is a directional film having a substantially rectangular shape of 40 mm and easily tearing in the longitudinal direction. The outer film (1) is provided with a score line (9) along the longitudinal direction substantially at the center in each of the longitudinal direction and the width direction. The length of the cutting line (9) is slightly larger than the width of the bottom of the rice ball (4), and is 35 to 40 mm in the embodiment.

The inner film (2) is formed by laminating a pair of substantially identical rectangular film pieces (21) and (21) on the side edges along the longitudinal direction of the film pieces (21) and (21) by about 7 mm. Formed,
It is a size that exactly overlaps with the outer film (1). In the embodiment, both film pieces (2) of the inner film (2) are used.
1) Point welding (22) is applied to the central portion in the longitudinal direction of the overlapping portion (20) of (21) so as to be easily peelable.

The intermediate film (3) has a length of about 220 mm, the same as the inner and outer films (1) and (2), and a width of the outer film.
It is slightly larger than half the width of (1). Intermediate film (3)
And the inner film (2) is formed of a moisture-proof film.

The outer film (1) and the inner film (2) are overlapped with their contours aligned, and an intermediate film is interposed between the two films (1) and (2).
(3) with one side edge along the longitudinal direction of the film inside and outside
(1) The outer peripheral edge is thermally welded by sandwiching it so as to coincide with one side edge along the longitudinal direction of (2). The heat welding is performed not on the entire outer periphery of the laminated film but on the film pieces (2) of the inner film (2).
1) The vicinity including the overlapping portion (20) of (21) is excluded.

A sheet-like food (8) such as a sheet of laver is accommodated between the intermediate film (3) and the inner film (2).

One side of the triangular onigiri rice (4) is placed at substantially the center in the longitudinal direction of the inner film (2) of the packaging sheet (7) in a direction perpendicular to the longitudinal direction of the sheet. Sheets are placed on both sides and packaged in the same procedure as in the conventional example shown in FIGS. Since the cut line (9) of the outer film (1) is slightly longer than the width of the bottom of the rice ball (4), the cut line (9)
Ends slightly extend on both sides of the triangle of the wrapped rice ball.

When wrapping, both overlapping ears (7
0) and (70) may be heat welded, but in the embodiment, they were stopped by the seal pieces (71) as shown in FIG. However, the sealing piece (71) has a shallow cut groove (7) on the extension of the cutting line (9) of the outer film (1).
When 2) is applied, when the outer film (1) tears to the left and right from the cutting line (9), it is necessary that the sealing piece (71) also tears together from the cutting groove (72).

The cutting line (9) of the outer film (1)
It is applied only to a substantially central portion in the longitudinal direction of the film,
Onigiri rice (4) is wrapped so that one side of the rice is placed so as to be orthogonal to the longitudinal direction at substantially the center of the wrapping sheet in the longitudinal direction. When displayed, the striated line (9) is almost hidden by the bottom of the rice ball, and both ends of the striated line (9) are only slightly visible.
The presence of (9) does not impair the appearance of the packaged rice ball.

The cutting line (9) is the same as the conventional film
(1) is shorter than the one applied over the entire length, and at the time of display, the cut line (9) is located on the bottom side of the rice ball, so that outside air can enter through the cut line (9). Is greatly reduced. For this reason, an intermediate film (3) for preventing invasion of outside air
It is not necessary to overlap the inner ends of the two film pieces (21) and (21) as in the prior art, and it is possible to use only one film capable of hiding the cutting line (9).

When eating onigiri rice, the outer film is centered on the cutting line (9) of the outer film (1) of the wrapped rice ball.
Pull both ends (13) and (13) of (1) left and right. Outer film (1)
Is a directional film which is easily torn in the longitudinal direction, so that the striated line (9) extends and the outer film (1) is torn, and is divided into right and left. When the both ends (13) and (13) of the outer film (1) are pulled to the left and right, the force tends to concentrate on the corners between the bottom surface and the triangular surface of the onigiri of the film. Since it extends slightly on both triangular faces, that is, beyond the bottom of the rice ball and the corners of the triangular face, a force acts effectively on the cutting line (9),
The outer film can be easily and beautifully torn.

When the outer film (1) is pulled right and left, the inner film (2) is also pulled together, and each film piece (21) (21) of the inner film (2) is divided into two parts. It is pulled together with the two film pieces (11) and (11) of 1) and slides out from between the sheet-shaped food (8) and the rice ball (4) to separate from the rice ball (4). By this, sheet food (8)
However, the rice balls (4) can be directly covered with the rice balls (4) and can be eaten with the rice balls covered with non-moisture sheet food.

FIG. 5 shows another embodiment in which the cutting line (9) of the outer film (1) is not continuous but intermittent. FIG. 6 shows another embodiment in which two cutting lines (9) are provided close to and parallel to each other, and three or more cutting lines (9) may be provided. Even when a plurality of the cutting lines (9) are provided, each cutting line (9) is
It can be an intermittent line like.

FIG. 7 is an exploded perspective view of another embodiment of a packaging film in which a narrow intermediate film (3) capable of covering the cutting line (9) of the outer film (1) is interposed.

In addition, the packaging rice ball sold at a convenience store or the like is not disposed of for a long time because the product rotates quickly and is discarded after the expiration time. Even if ()) is omitted, the moisture of the sheet-shaped food (8) does not progress to a problematic degree. Of course, it is also possible to use an intermediate film composed of two film pieces (31) and (31) in the same manner as in the prior art.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims.
