BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice wrapping film for packaging rice for making rice balls and a packaging material in separate states, and a rice and packaging material for making rice balls. The present invention relates to a rice ball package that is packaged. Here, the rice ball means rice wrapped with a cover material such as sheet seaweed.

[0002]

2. Description of the Related Art A conventional wrapping film 20 for a rice ball for packaging rice Y and sheet laver X1 as an example of a cover X in separate states is a rectangular outer film 2 and a rectangular inner film. It is a stack of three. More specifically, as shown in FIGS. 16 and 17, the inner film 3 is composed of two rectangular films 31 and 32 having substantially the same shape, and their longitudinal edges 31a and 32a are polymerized without being adhered. There is. The dimensions of the two superposed inner films 31, 32, that is, the dimensions of the two superposed inner films 31, are the same as those of the outer film 2, and the peripheral edges 31b, 31c, 31d, 32b, 32c, 32d of the inner film 3 are The peripheral edges 2 a, 2 b, 2 c and 2 d of the film 2 are aligned and overlapped on the outer film 2. Further, the peripheral edges 2a, 2b, 2c and 2d of the outer film 2 are not
Peripheral edges 31b, 31c, 31d, 32b, 32c, 32
It is bonded to d by heat welding. That is, of the peripheral edges of the two inner films 31 and 32, the non-overlapping peripheral edges are bonded to the peripheral edge of the outer film 2 by heat welding (the shaded portion in FIG. 16 is the heat welded portion). And
In this way, the outer packaging material packaging portion 10c capable of packaging the outer packaging material X is formed between the inner film 3 and the outer film 2.

In such a conventional wrapping film 20 for rice balls, the sheet laver X1 is wrapped in the cover packaging portion 10c between the outer film 2 and the inner film 3, and the rice Y is brought into contact with the inner film 3 in that state. Then, the conventional rice ball package 30 can be obtained by wrapping it.

Specifically, in the case of packaging triangular prism-shaped rice Y1, as shown in FIG. 18, one side of the triangular prism-shaped rice Y1 is formed on the upper half of the conventional packaging film 20 for rice balls in the longitudinal direction. Is placed, and the remaining portion (corner portion, etc.) of the upper half portion in the longitudinal direction is the triangular prism-shaped rice Y.
1 to the other surface side (arrow in FIG. 18), and then to FIG.
As shown in FIG. 9, the other surface side of the triangular prism-shaped rice Y1 is similarly wrapped with the lower half portion of the conventional packaging film 20 for rice balls, and the remaining lower half portion (corner portion). Etc.) to the one surface side of the triangular prism-shaped rice Y1 (arrow in FIG. 19), and finally, the remaining portion of the lower half in the longitudinal direction is heated to the outer film 2 existing on the one surface side of the triangular prism-shaped rice Y1. Weld (see FIG. 19, shaded portion 2)
1 is a heat-sealed portion), a conventional rice ball package 30 can be obtained. Further, in such a conventional rice ball package 30, when the rice Y and the sheet laver X1 are eaten as rice balls (the rice Y is wrapped with the exterior material X), the outer film 2 is divided in the longitudinal direction. By,
The conventional rice wrapping film 20 can be easily removed to combine the rice Y and the cover X.

As described above, in the triangular-pillar-shaped rice Y1, the conventional packaging film 20 for rice balls can be fixed relatively well by heat welding, but the rice Y that is not in the triangular-pillar shape, for example, in the shape of a cylinder or a bales. When packaging the rice Y, it may be difficult to fix the conventional packaging film 20 for rice balls by heat welding. That is, when the rice Y is a cylindrical rice Y2, as shown in FIG. 20, first, the circular surface of the cylindrical rice Y2 is placed at the center of the rectangular conventional rice ball wrapping film 20, Adjacent parts of the conventional wrapping film for rice balls 20 in the short side direction facing each other in the vicinity of the edges 20a and 20b are overlapped so that the front surface and the back surface of the conventional wrapping film for rice ball 20 are in contact with each other (see FIG. The shaded portion 21 of 20 is a heat-welded portion). By such operation,
Conventional wrapping film for rice balls that has a roughly cylindrical shape 2
In the center portion of 0, the cylindrical rice Y2 exists. Subsequently, as shown in FIG. 21, a surplus portion 10b of the conventional packaging film 20 for rice balls that is not directly involved in the packaging of the cylindrical rice Y2, here, the length of the conventional packaging film 20 for rice balls. A rice wrapping portion 10a, which is a portion around the peripheral edge in the direction, which wraps the cylindrical rice Y2 of the conventional packaging film 20 for rice balls.
It is folded back so as to come into contact with and heat-welded (the shaded portion 21 in FIG. 21 is the heat-welded portion).

However, as shown in FIG. 22, in the conventional packaging film 20 for rice balls, since the outer film 2 and the two inner films 31, 32 partially polymerized have substantially the same size, at least four or more, Normally, it is necessary to heat-bond 10 films. Further, in order to heat-weld such a number of sheets, there are problems that a high temperature and a long time are required, the cost becomes high, and the heat-welded portion is easily detached during transportation or display.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. For convenience of description, the terms such as the short-side direction and the long-side direction are used, but the meaning is not limited to the meaning that the portion referred to as the longitudinal direction is longer than the portion referred to as the short-side direction.

As shown in FIGS. 1 and 2, a packaging film 1 for rice balls comprises an outer film 2 and two inner films 3
(31, 32). The outer film 2 is made of a resin film having a heat-welding property and has a rectangular shape. Then, a dividing means (for example, a cut tape 4) that divides the outer film 2 in parallel with the longitudinal direction is provided on the inner surface of the outer film 2 in the lateral center portion. In addition, the lateral edges 2c and 2d of the outer film 2 in the lateral direction
A pair of notches 7, 7 are engraved in the vicinity of the cut tape 4 in between. Also, two inner films 3
1, 32 are also made of a resin film having a heat-welding property,
It has a rectangular shape smaller in size than the outer film 2. Further, the two inner films 31 and 32 have substantially the same shape.

The two inner films 31, 32 are partially non-adhesively polymerized at the peripheral edges 31a, 32a in the longitudinal direction, and the outer film 2 is the inner films 31, 32.
Non-overlapping perimeters 31b, 31c, 31d, 32 of
Of b, 32c and 32d, from the peripheral edges 31b and 32b,
It is arranged on the outer film 2 so as to extend outward in a substantially equal width. That is, the two partially overlapped inner films 31 and 32, which are smaller than the outer film 2 in size, are placed on the outer film 2 at substantially the center position of the outer film 2, thereby Edges 2a, 2b
A portion having a substantially equal width, in which the inner film 3 does not overlap the outer film 2, is formed in the vicinity of the area. This portion of the outer film 2 where the inner film 3 does not overlap, that is, the portion where the outer film exists alone corresponds to the single film portion 5.

Further, the lateral edges 31c, 31d, 32c and 32d of the inner films 31 and 32 and the longitudinal edges 31b and 32b (that is, the longitudinal edges 31a and 32).
The peripheral edges of the inner films 31 and 32 excluding a are bonded to the outer film 3 by means such as heat welding (see FIG. 1).
(Refer to the shaded area is the heat welded area.)
A cover part 1 for packing a cover part X such as sheet laver X1 between the outer film 2 and the inner films 31, 32.
0c is formed (see FIG. 2).

Next, with respect to the method for producing and using the packaging film 1 for rice balls according to the present invention, and the rice ball package 10 according to the present invention, an example is shown in which non-triangular rice Y having a cylindrical shape or the like is packaged. To explain.

First, the packaging film 1 is manufactured by placing a rectangular sheet laver X1 or other covering material X on the substantially central portion of a rectangular outer film 2 provided with a cutting means in the longitudinal direction, and then laminating the sheet laver X1. While the two inner films 31, 32 are partially polymerized so as to be larger than the size of the sheet laver, that is, so as to cover the entire surface of the sheet laver X1,
Further, the sheet is placed on the sheet laver X1 so that the partially polymerized portion is located substantially in the center of the outer film 2. At that time, the size of the two partially overlapped inner films 31 and 32 combined is smaller than the size of the outer film 2. And the peripheral edge 2 of the outer film 2
A single film portion 5 is a portion formed in the vicinity of a and 2b and having a substantially equal width, in which the inner film 3 does not overlap the outer film 2.

Then, in the inner films 31, 32,
The portion of the sheet seaweed X1 that protrudes outside the periphery can be bonded to the outer film 2 by heat welding or the like to manufacture the packaging film 1 for rice balls in which the sheet seaweed X1 is packaged in the exterior packaging portion 10c. As described above, in the packaging film 1 for rice balls, since the cover material X such as the sheet laver X1 is packaged in the cover material packaging portion 10c, it is difficult for the cover material X to come into direct contact with the rice Y. There is little risk that the rice ball will not be delicious due to the absorption of water in the rice Y.

The wrapping film 1 for rice balls produced in this way is cooked with the rice Y so that it faces the inner film 3.
It is used as a packaging material for packaging. Specifically, as shown in FIG. 3, on the inner film 3 in the longitudinal upper half of the packaging film 1 for rice balls, the cylindrical rice Y2, which is solidified into a cylindrical shape, is inserted into the cylindrical rice Y2. One of the two circular surfaces is placed as a contact surface, then, while bending the lower half portion of the packaging film for rice balls 1 in the longitudinal direction so that the remaining one circular surface of the cylindrical shape is covered, Wrap the cylindrical rice Y2 as if wrapped.

In order to prevent the packaging film 1 for rice balls, which has a cylindrical shape around the cylindrical rice Y2, from unintentionally reopening, the packaging film 1 for rice balls overlapped on the circular surface of the cylindrical rice Y2. Around the edge in the lateral direction of
It is adhered by heat welding or the like or is fixed by an adhesive member such as a sticker seal (the shaded portion 21 in FIG. 3 is a heat welded portion).

Next, as shown in FIG. 4, a surplus portion 10b, which is a portion near the peripheral edge in the longitudinal direction of the wrapping film 1 for rice balls, which is not directly related to the packaging of the cylindrical rice Y2, is formed into a cylindrical shape. The rice Y2 is folded so as to overlap with the rice packaging portion 10a (the central portion of the packaging film 1 for rice balls in the lateral direction) that is the portion that directly packages the rice Y2. The single film portions 5a and 5b in the bent surplus portion 10b and the single film portions 5a and 5b
And the outer film 2 of the rice wrapping portion 10a, which are in contact with each other, are adhered by heat-welding to substantially determine the form after wrapping, and the rice ball package 10 is formed (the hatched portion 21 in FIG. 4 is heat-welded). part).

At this time, the packaging film 1 for rice balls according to the present invention is provided with the single film portion 5 in which the inner film 3 does not overlap the outer film 2, and the single film portion 5 is heat-welded. Therefore, as shown in FIG. 5, if there are few films, at most three films (outer film 2) may be heat-welded to the outer film 2 of the rice packing portion 10a at a high temperature or for a long time. It is possible to perform the adhesion that does not easily come off and does not come off.

Then, the rice Y and the outer packaging X of the rice ball package 10 formed as described above are eaten in the same manner as the conventional rice ball package 30. Specifically, the cut film 4 provided on the outer film 2 is pulled in the vicinity of the notch 7 as a starting point to divide the outer film 2 in the longitudinal direction, the outer film 2 is removed, and The inner films 31, 32 are opened to expose the exterior article X from the exterior article packaging portion 10c,
Next, the cover X is brought into close contact with the rice Y, and the cover Y is used for the rice Y.
Eat it after rolling it into a rice ball.

Further, in the packaging film 1 for rice balls according to the present invention, as shown in FIG. 6, an adhesive label 15 for displaying a product is placed on the rice ball package 10 so as to cover the bent excess portion 10b. It can also be attached.
In this rice ball package 10, the pair of notches 7, 7 engraved in the vicinity of the cut tape 4 are also covered by the adhesive label 15, so that the outer film 2 cannot be divided from the notch 7 as a starting point. Therefore, a notch 7 that crosses the cut tape 4 is further formed in a portion of the outer film 2 where the adhesive label 15 is not attached, and the notch 7 is covered on the surface side of the outer film 2. It is also possible to attach the pick-up label 16 to the above, or to attach a sealing label covering the notch 7 on the back side of the outer film 2.

Further, in the above-described embodiment, as shown in FIG. 7, a structure in which the surplus portion 10b is bent in the direction toward the surface on which the outer film 2 is superposed (the direction of arrow I in FIG. 7) is described. However, the direction opposite to this direction, in which the outer film 2 is not overlapped (see FIG. 7).
It can also be bent in the direction of arrow II). When the surplus portion 10b is bent in such a direction, the notch 7 engraved on the peripheral edge of the outer film 2 may be covered even if the sticking label 15 is stuck so as to cover the bent surplus portion 10b. Absent. Therefore, it is not necessary to further engrave the notch 7 or to attach the knob label 16 to other than the peripheral edge of the outer film 2.

Further, in the above-mentioned embodiment, the peripheral edge of the packaging film 1 for rice balls in the lateral direction is superposed on the circular flat surface (the bottom surface or the top surface of the cylindrical shape) of the cylindrical rice Y2. As shown in FIG. 8, it is also possible to superimpose them on a cylindrical side surface. Then, the surplus portion 10b of the outer film 2 is bent in the direction of the circular flat surface (the bottom surface or the top surface of the cylindrical shape) of the cylindrical rice Y2 (the direction of the arrow in FIG. 8). In the rice ball package 10 thus formed, the notch 7 engraved on the peripheral edge of the outer film 2 is not covered even if the sticking label 15 is stuck so as to cover the bent excess portion 10b. . Therefore, it is not necessary to further engrave the notch 7 or to attach the knob label 16 to other than the peripheral edge of the outer film 2.

In the first embodiment, the single film portion 5 is provided on a part of the outer film 2, but in the second embodiment, for example, the outer film 2 is used.
Can also be separate films. That is, for example, the single film partial member 51, which is an example of the individual film, can be separately provided to the outer film 2.

Specifically, first, a film single piece partial member 51 is manufactured by processing a film having a heat-welding property into, for example, a tongue shape, and then, as shown in FIG. The outer edge of the outer film 2
The single film portion 5 is provided in the vicinity of a and 2b by providing it by means such as heat welding or adhesion with an adhesive. More specifically, the peripheral edges 2a and 2b of the outer film 2
In the above, the positional relationship in which the single film portion 5 provided on the peripheral edge 2a and the single film portion 5 provided on the peripheral edge 2b are substantially opposed to each other at the substantially central position thereof and / or at the position near the end thereof. It is provided so that. This is because by providing the single film portion 5 in this way, it is possible to wrap with the minimum number of single film portions 5 and / or the area.

As shown in FIG. 10, the wrapping film 1 for rice balls having the single film portion 5 thus provided is also used as a packaging material for wrapping the rice Y in the same manner as in the first embodiment. used. Then, as shown in FIG. 11, the surplus portion 10 of the packaging film 1 for rice balls
When heat-sealing b to the outer film 2 of the rice packaging portion 10a, not the single film portion 5 of the outer film 2 in the first embodiment, but the single film portion of the single film portion member 51. 5 by heat welding (FIGS. 10 and 1)
The shaded portion 21 of 1 is a heat welded portion).

Further, even if the single film portion 5 is a part of the outer film 2, or the single film portion member 5 is used.
Even if 1 is added to the outer film 2, the portion where the single film portion 5 is provided is not particularly limited. For example, the shape of the rice Y, the shape of the rice ball packaging film 1, and the packaging method ( It can be changed as appropriate in consideration of how to wrap rice Y).

For example, when the single film portion 5 is provided on a part of the outer film 2, in the first embodiment, the single film portion 5 is provided near the peripheral edges 2a and 2b of the outer film 2. Only the portion that needs to be heat-sealed, more specifically, as shown in FIG. 12, for example, near the corners of the outer film 2 having a tetragonal shape, and / or the peripheral edges 2a, 2b of the outer film 2, It can also be the central portion of at least one of the edges 2c and 2d.
In such a packaging film 1 for rice balls, the size of the single film portion 5 can be reduced, so that the size of the packaging film 1 for rice balls can be reduced. Moreover, when the size of the packaging film 1 for rice balls is not changed, the size of the outer packaging part 10c can be increased and a large outer packaging X can be packaged.

Further, from the viewpoint that the same packaging film 1 for rice balls can be used for various forms of rice Y and various packaging methods, as shown in FIG. Along with the peripheral edges 2a, 2b, 2c, 2b of the film 2, a single film portion 5 larger than the other portions may be provided at the corners. According to such a packing film 1 for rice balls, for example, as shown in FIG. 14, a triangular prism-shaped rice Y1 smaller than the rice Y that is normally used can be packaged by heat welding only once.

Also, in the packaging film 1 for rice balls, which is provided with the single film portion 5 provided by adding the single film portion member 51 to the outer film 2,
Similar to the case where the single film portion 5 is provided in a part of the outer film 2, the position of the single film portion 5, in other words, the position where the single film portion member 51 is added or the single film portion member 51 of the film. The shape etc. can be determined. Further, in the above-described embodiment, the single film portion 5 is provided on the outer film 2, but the present invention is not limited to this configuration and can be provided on the inner film 3.

Further, the shape of the packaging film 1 for rice balls is not limited to the above-mentioned tetragonal shape, and for example, as shown in FIG. 15, the four corners of the tetragon may be cut out. . In the packaging film 1 for rice balls, for example, when the spherical rice Y is packaged, the size of the excess portion 10b can be reduced, and the appearance of the rice ball packaging body 10 can be improved.

Further, in the above-mentioned embodiment, the rice Y is mainly the cylindrical rice Y2 as an example, but the rice Y is not limited to this structure, and for example, triangular rice Y1 and other bales can be used. It can also be a square pole rice Y or the like. Further, in the first embodiment, the surface mount X
The sheet seaweed X1 has been illustrated, but the present invention is not limited to this configuration, and thinly roasted eggs or film-like kelp can be used, for example.
