Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is an explanatory view of a rice packaging material (hereinafter simply referred to as a packaging material) 10 for packaging rice such as rice balls or sushi, and FIG. 2 is an explanatory view of a rice packaging body (hereinafter simply referred to as a packaging body) 26.
The wrapping material 10 has a rectangular shape, an outer film 14 provided with a separable portion 12 made of a known cut tape or the like in parallel with the long side and over the entire length in the longitudinal direction, and two films. Inner films 16a and 16b that are superimposed on the outer film 14 in a state where the edge portions in the width direction overlap each other and are fixed to the outer film 14 at appropriate positions on the peripheral edge, and the outer film 14 and the inner films 16a and 16b It is composed of a food sheet 18 such as a seaweed or a kumbu sheet interposed between them. In addition, the rectangular shape includes a substantially rectangular shape such as a cut-out corner.

The outer film 14 and the inner film 16 are fixed by heat welding or the like.
The welding portion (the hatched portion in FIG. 1) is not particularly limited, but when the outer film 14 is divided into two by the separable portion 12, one divided outer film 14 and one inner film piece 16a The other divided outer film 14 and the other inner film piece 16b are provided at positions where they can be separated. In other words, the welded part between one divided outer film piece 14 and one inner film 16a and the welded part between the other divided outer film piece 14 and the other inner film 16b form the separable portion 12. They are placed on opposite sides of each other.

The packaging material 10 is used to wrap rice such as sushi or rice balls (hereinafter described as sushi) 20 to form a hand-rolled sushi-style rice package (hereinafter simply referred to as a package) 26 (FIG. 2). Is as follows.
First, the sushi 20 formed in a conical shape is placed on the inner film 16 of the packaging material 10 so that the top part faces the middle part of one long side 10d of the packaging material 10 (the bottom part faces the corner part B). The slant is arranged at an angle of about 45 degrees with respect to the packaging material 10.

Next, the triangular portion of the packaging material 10 having the corner portion A side sandwiched between the one long side 10d and the one short side 10a as the apex is wound along the outer shape of the sushi 20, and the inner winding portion 22 is wound. (FIG. 2).
Next, a portion having a predetermined width on the other short side 10b side of the packaging material 10 is wound on the inner winding portion 22 to form the outer winding portion 24 (FIG. 2).
Then, the outer wrapping portion 24 is appropriately formed on the inner wrapping portion 22 by a sealing material (not shown), a heat seal or the like and formed on the package 26. In FIG. 2, the sushi 20 is omitted.

And in this Embodiment, as shown in FIG. 2, the separable part 12 of the outer film 14 of the site | part used as the inner winding part 22 is not covered by the outer winding part 24, Therefore, this separable part 12 is exposed over the entire length of the outer film 14.
Thus, since the separable part 12 of the outer film 14 is not covered by the outer winding part 24 of itself but is exposed over the entire length of the outer film 14, the outer film 14 is divided by the separable part 12. At this time, the separable portion 12 is not obstructed by the outer wrapping portion 24, and the outer film can be easily separated, and the food sheet 18 is removed from the sushi 20 while leaving the food sheet 18 on the sushi 20 together with the separated inner film 16. be able to.

FIG. 3 shows the separation start position P of the separable portion 12 and the separation end position Q of the separable portion 12 when the packaging body 26 is held in the hand. It will be understood that the package 26 can be easily grasped and the operation of separating the outer film 14 by the separable part 12 is extremely easy because it is exposed over the entire length.
In addition, when fixing the outer winding part 24 on the inner winding part 22 using the sealing material 17, when the sealing material 17 hangs (covers) on the separable part 12, as shown in FIG. The end edge of the outer wrapping portion 24 at the part where the lip is pasted is slightly cut away (notch portion 17a), and the end edge is retracted so that the sealing material 17 does not hang over the separable portion 12. It is good to. In addition, the position where the outer winding part 24 is fixed to the inner winding part 22 by the sealing material 17 or the heat seal is shown in FIG. 3 so that the outer films separated vertically are not fixed by the sealing material or the heat sealing. As shown, it is arranged so that it is closer to the top side (lower side) of the package 26 than the position of the separable part 12.

In the package 26, as shown above, as an example, the detachable portion 12 of the outer film 14 is not covered by the outer winding portion 24 and is exposed over the entire length of the outer film 14, as shown in FIG. Such a packaging material 10 may be used.
In the packaging material 10 shown in FIG. 4, the separable portion 12 is provided at the center in the width direction of the outer film 14.
And the length of the long side 10c of the packaging material 10 is set to the length of 1.5 times or less of the length of the short side 10a (10b).
Note that the length of the short side 10a of the packaging material 10 (the width of the packaging material) is preferably 10 cm or more because of the necessity of easy gripping when formed on the package.

The case where sushi 20 is packaged using this packaging material 10 is demonstrated. In addition, in order to make description easy to understand, the sushi 20 is omitted.
As shown in FIG. 5 (A), the triangular portion on the one corner portion A side on the one short side 10a side of the packaging material 10 (shaded portion in FIG. 4: part of which is an inner winding portion) is folded back. (In fact, it is folded in an arc along sushi). That is, the corner portion A side is folded so that the long side (one long side) 10d on the one corner portion A side is perpendicular to the long side (the other long side) 10c on the other corner portion B side. . At this time, since the sushi is wrapped inside, it does not actually overlap, but when viewed from the direction of FIG. 5 (A), the short side 10a appears to overlap the long side 10c, Appearance is improved when packaged. Note that FIG. 5B is a diagram viewed from the X direction in FIG.

Next, as shown in FIG. 6 (A), the part of the required width on the other short side 10b side of the packaging material 10 (the hatched portion in FIG. 5 (A)) is folded back and the long side 10d of the folded part is folded back. As the base line, it is folded back so as to overlap the corner portion A side (actually, it is folded in an arc along the sushi) to form the outer winding portion 24. The part covered with the outer winding part 24 is nothing but the inner winding part 22. In this case, the long side 10c of the packaging material 10 overlaps with one short side 10a (FIG. 6A), and the appearance is good.
The outer wrapping portion 24 is fixed to the inner wrapping portion 22 with a sealing material (not shown), heat sealing, or the like, thereby completing the package 26. Appropriate ingredients (not shown) are placed on the exposed portion of sushi. FIG. 6B is a view as seen from the X direction in FIG.

  By setting the length of the long side 10c to 1.5 times or less the length of the short side 10a, the short side 10b does not reach the separable portion 12, as shown in FIG. It will be appreciated that the separable portion 12 of the outer film 14 is exposed over its entire length.

In the embodiment described above, the separable portion 12 is provided in the central portion in the width direction of the outer film 14, but as is apparent from the above description, for example, the length of the long side 10c is set to 1 of the length of the short side 10a. If the length of the small magnification is set to about 3 times, the separable part 12 can be provided even if the separable part 12 is provided at a position closer to the long side 10d from the center of the short side 10a. Can be exposed over the entire length.
Contrary to the above, if the position of the separable part 12 is shifted from the center of the short side 10a toward the long side 10c, the length of the long side 10c is 1. Even if it is set to be larger than 5 times, for example, about 1.8 times, the separable part 12 can be exposed over the entire length. Thus, if the position of the separable part 12 is provided at a position shifted to the long side 10c side, the separable part 12 shifts to the upper side (upper side of hand-rolled sushi, etc.) when formed on the package 26. Therefore, it becomes easy to grasp the lower part of the package 26, and this is also preferable.

To summarize the above, as is clear from FIG. 7, (the length of the long side 10c−the length of the short side 10b): M ≦ (the distance from the long side (one long side) 10d to the separable portion 12). When N is set, the separable portion 12 is not covered by the outer winding portion 24 when the short side 10b side is folded with the long side 10d as the base line.
When the separable portion 12 has a certain width, the above (distance from the long side 10d to the separable portion 12) means that the separable portion 12 on the side closer to the long side 10d from the long side 10d. The distance to the edge. Further, as shown in FIG. 8, the separable portion 12 may be provided so as to be bent with a certain width. In this case, the above (distance from the long side 10d to the separable portion 12). The distance from the long side 10d to the edge of the separable part 12 on the side close to the long side 10d is the shortest distance.

  As another embodiment, (length of long side 10c−length of short side 10b): M> (distance from long side 10d to separable portion 12): As shown in FIG. 9, when the folding base line of the outer folded portion 24 is set at a position shifted by an appropriate distance Y from the folded long side 10d, the separable portion 12 can be exposed over the entire length. In this case, sushi or the like is exposed at the apex of hand-rolled sushi or the like.

  The separable portion 12 may be a perforation provided on the outer film 14 in addition to a cut tape, an orientation film that can easily tear the outer film 14 in the longitudinal direction, or the outer film 14 in the width direction. It is good also as a separable part by dividing | segmenting and welding partially.

  Moreover, in each said embodiment, as shown in FIG. 1, when two films of the inner film 16 are comprised from the wide film piece 16a and the narrow film piece 16b narrower than this wide film piece 16a. Is preferred. In this case, if the narrow film piece 16b is positioned on the long side 10d side of the packaging material 10, it is preferable because the divided film can be easily pulled out from the sushi as will be described later. In addition, as for the site | part with which both the inner film pieces 16a and 16b overlap, either may be inside or an outer side. One or both of the overlapping film pieces may be further folded in two (not shown).

  Further, the corner portion of the food sheet 18 on the corner portion A side may be cut out as shown in FIG. Thereby, as described later, when the divided film is pulled out from the sushi, the film piece is not caught at the corner portion of the food sheet 18, which is preferable.

  As described above, when the outer film 14 is divided into two by the separable portion 12 by making the inner film 16 into the wide film piece 16a and the narrow film piece 16b, the upper portion (corner portion) of the outer film 14 is divided. The portion B) and the wide film piece 16a of the inner film 16 fixed to the upper portion can be easily pulled upward with the food sheet 18 left on the sushi 20. The wide film piece 16a of the inner film 16 has a greater resistance to the sushi 20 as much as it is formed, making it difficult to pull out, but because it is pulled out to the open space above the sushi 20, the food sheet 18 is interposed. Even if it does, it is not disturbed by the foodstuff sheet | seat 18, and pulls out easily.

  Rather, the lower part of the divided outer film 14 and the narrow film piece 16b of the inner film 16 fixed to the lower part have a food sheet 18 that swells downward. Although it is difficult to pull out downward, the inner film 16 is formed into a narrow film piece 16b, so that it is easily peeled off from the food sheet 18 and the sushi 20 and is easily pulled out.

  In particular, the portion of the narrow film piece 16b on the short side 10a side of the corner portion A in FIG. 1 should not be welded to the outer film 14, and / or the food sheet 18 at that portion should be cut out. Thus, it becomes possible to pull out the divided film more easily.

  In addition, edible oil can be mixed in the sushi rice in order to make it easier to pull out the divided film. Alternatively, cooking oil may be applied to the inner surface side of the inner film 16. Moreover, you may make it easy to pull out the divided | segmented film by making edible powders, such as rice flour, adhere to the surface of sushi or a rice ball, suppressing stickiness of sushi etc. and making it slippery.

  In addition, in the said embodiment, in order to make description easy to understand, it demonstrated by the example which forms the packaging body 26 so that the packaging material 10 may be wound around the sushi 20 shape | molded in cone shape. However, in actuality, when the packaging body 26 is formed, the packaging material 10 is previously formed in a deformed cone shape as shown in FIG. 2, and the conical shape is formed in the packaging material 10 formed in the deformed cone shape. It is preferable that the sushi 20 formed in the above is dropped and formed on the package 26. By doing so, the packaging material 10 formed in a deformed cone shape in advance is continuously fed into an apparatus (not shown) sequentially, and the sushi 20 shaped in a cone shape in advance is dropped into the packaging material 10 in sequence. Can be automated.

The structure of the packaging material 10 formed in advance in a deformed conical shape (shown in FIG. 2) is expressed as follows.
That is, one corner part A sandwiched between one short side 10a and one long side 10d of the packaging material 10 is located in the middle part (on the middle part) of the other long side 10c facing, A portion on the corner portion A side is wound as the inner winding portion 22, and a portion on the other short side 10 b side of the packaging material 10 is wound on the inner winding portion 22 as the outer winding portion 24 and on the inner winding portion 22. By fixing, the structure of the packaging material formed in the deformation | transformation cone shape by which the middle part of one long side 10d becomes a top part is made (FIG. 2).

10 and 11 show an embodiment in which the package 26 is covered with a cover (cap) 28 so as to cover the exposed portion of the sushi 20 (the bottom side of the cone).
In the example of FIG. 10, a cover 28 is put on the outer side of the package 26, and the cover 28 may be fixed to the package 26 by a separate fixing seal (not shown) or the like. It is preferable that the cover 28 be removed at the same time when the outer film 14 is divided by the separable portion 12.
FIG. 11 shows an example in which the skirt of the cover 28 is put on the package 26 so as to be sandwiched between the upper inner sides of the package 26 (between sushi and the packaging material).

12 and 14 show an example in which the cover 28 is provided integrally with one end edge 14a of the outer film 14 of the packaging material 10, and FIG. 13 shows the cover 28 adjacent to one end edge 14a. The example provided in the edge part 14c, FIG. 15 shows the example which provided the cover 28 over the both-ends edge 14a, 14c. FIG. 16 shows an example in which the cover 28 is provided over both end edges 14a, 14b and 14c.
When the cover 28 is provided on the end edge portion 14c side as in the example shown in FIGS. 13 and 15, the separable portion 12 is extended to the cover portion on the end edge portion 14c side, etc. The cover 28 is also separable (not shown). Alternatively, as shown by hatching in FIGS. 13 and 15, the cover 28 may be fixed to only one portion of the outer film 14 divided by the separable portion 12 by welding or the like. In FIGS. 12-16, what was shown with the broken line has shown the position which mounts triangular pyramid-shaped sushi or rice ball.

  The outer film 14 and the inner film 16 are preferably thin resin sheets, but the material is not particularly limited, and may be a paper material or the like.
