DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrapping rice ball for packing nigiri rice in a state separated from laver, a method for producing the same, and a wrapping film.

[0002]

2. Description of the Related Art Conventionally, rice balls and seaweed are packaged in a separated state to be hygienic and fresh in seaweed, and when seafood is eaten, seaweed is combined with rice and rice is used to obtain various seaweed rolled rice balls. It has been proposed in the configuration.
In these, a laver smaller than the outer shape of the outer film is layered on the inside of the outer film of the rectangular body, and further on the inside, two inner films having a width slightly larger than the width of the outer film divided in two in the longitudinal direction, At the center of the outer film, a part is overlapped with each other, the outer peripheral edge is overlapped with the outer peripheral edge of the outer film, and the inner and outer films are adhered along the outer peripheral edge. There is a packaged rice ball on which rice is placed, the other half is folded along the rice ball, the triangular protruding portions of the inner and outer films are folded, and a label is attached thereon.

[0003] When eating the wrapped rice ball, the label is peeled off, the wrapping film is opened, the nigiri rice is placed on one half of the inner film, the inner film on the other half is peeled off, and the exposed laver is removed. And then put the rice back on the other half of the inner film with the laver down, peel off the inner film on one half side, fold the laver over the rice, and wrap the laver on the laver. It is obtained. However, in this packaged rice ball, when the laver is combined, the rice ball and the laver may be exposed from the inner film and become unsanitary, and the laver is re-mounted on the inner film to combine the laver. However, the rice balls easily slipped off the packaging film, and it was troublesome to obtain laver rolled rice balls.

In order to solve such a drawback, a triangular rice ball is formed in a conical shape so as to substantially follow the outer shape of the rice.
Using a packaging film in which laver is interposed between an outer film formed with perforations that can form a small hole by separating the tip portion and an inner film having substantially the same shape as the outer film, the inner film of this packaging film There is a wrapping rice ball in which rice is inserted into the inside, the opening is folded, and a label is attached.

[0005] In this packaged rice ball, if the perforation is cut off and the leading end is removed, the leading end of the inner film is exposed. When the label is peeled off, the folded portion is opened. Nori rolled rice balls are obtained, and the operation when eating is simple and sanitary. However, the inner film easily sticks to the periphery of the rice, and it must be removed from the small hole of the outer film, so it cannot be extracted smoothly, and if you try to forcibly extract it, you will tighten the rice strongly. There was a drawback that the mold was easily broken.

In order to solve this drawback, a small nori is appropriately laminated on the inner side of the outer film in which a cutting means such as a cut tape is formed in the longitudinal direction of the central portion of the rectangular body. The width of the hand is slightly wider than the width of the outer film divided into two, and the inner film is overlapped so that the inner film is aligned with the outer film outer peripheral edge and the center part is superimposed on each other,
There is a wrapping rice ball wrapped with a wrapping film obtained by heat-sealing the inner and outer films along the outer peripheral edge of the outer film.

[0007] If the outer film is divided into right and left by a dividing means, the inner film is a divided type in which two films are superimposed at the center, so that the whole packaging film is divided into two parts. By pulling the halves to the left and right, the laver can be combined with the rice and the laver can be easily obtained. However, one side of the rice is folded in half along the short side of the central part, and both corners protruding in a triangular shape are sequentially folded on the rice, and a label is attached to the overlapping portion. Therefore, the division by the dividing means is caught at the overlapping portion, and it is difficult to perform simple and accurate division. From this, notches are formed at the corners, such as by diagonally notching both corners so as not to overlap each other, with the idea of reducing the overlapping portion on the dividing means and not obstructing the dividing. What has already been proposed.

[0008]

However, although the above-mentioned notch portion is preferable in that the overlap with the dividing means is reduced and the dividing itself is facilitated, the two corner portions are notched. Part of the rice is reduced, so that the rice is not covered enough and partially exposed, or
Since the overlap is reduced, the number of folded portions is reduced, the number of parts that can be fastened is limited, and there is a possibility that the fastening by the label may be insufficient.

On the other hand, irrespective of whether or not the notch is formed, in order to fasten both folded portions, the root side portion of the folded portion is thermally fused and fastened and folded on the dividing means. Labels are attached to both corners. Therefore, when dividing, the label itself must be divided, for example,
If the cutting means is cut tape, the cut tape may break during the cutting, or if the cutting is forcibly attempted, the nigiri rice may be deformed by applying excessive force to the nigiri rice. There were things that were difficult to do. In addition, even after cutting, the root part of the fold remains heat-sealed, so it is difficult to cut it smoothly when cutting one half to the left and right, and the seaweed part sandwiched between the folds is torn There was a problem that it was easy.

According to the present invention, there is provided a packaging rice ball which is obtained by folding the packaging film into a plurality of layers and further applying a label on a separating means for opening.
The production method and the packaging film were found to have problems, and in order to solve the problem, the composition of the packaging rice ball, the production method thereof, and the composition of the packaging film were fundamentally improved. However, the purpose is to fold rice rice in a folded state with nori in the inner and outer films, so that rice can be packaged simply and securely.Moreover, when eating after production, it can be opened easily and easily. An object of the present invention is to provide a packaged onigiri from which a laver rolled onigiri can be obtained, a method for producing the same, and a packaging film.

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, a packaged rice ball 1 according to the present invention is made into a packaging film by laminating a laver 4 between an outer film 2 and an inner film 3, and using this packaging film to make a rice ball 5. Is packaged.

The outer film 2 is a rectangular film made of an arbitrary synthetic resin, preferably biaxially stretched, and wraps the triangular rice balls 5 in a state of being folded in the longitudinal direction. A perforation 7 is provided as separating means along both short sides to separate the short side into a separation piece 6, and cuts 8 for tear guide are provided at both ends thereof. The outer peripheral edge portion other than the portion where the separation piece 6 is formed has a bonding margin (clearable width for bonding) 9.

The inner film 3 is made of an arbitrary synthetic resin, preferably a polyethylene terephthalate (PET) film, which has been subjected to silicon processing, or a mat film which has been subjected to mat processing. It is a rectangular film made of a synthetic resin whose surface is processed and processed so that the frictional resistance is reduced, and is smaller than the outer shape of the outer film 2.

Using the inner and outer films 2 and 3 and the laver 4, the packaged rice ball 1 of the present invention can be manufactured as follows. First, a small laver 4 is laid on the inner surface of the outer film 2, and the inner film 3 is further laid on the inner side of the inner film 3 so as to be located inward of the adhesion allowance 9 of the outer film 2. Only the hand side portion 10 is overlapped with only one of the separating pieces 6 on both sides, and the rice 5 is placed on the inner film 3 (FIG. 4).

Next, the polymerized outer film 2, seaweed 4, and inner film 3 are simultaneously folded in two to form rice balls 5
Is folded over on the opposite side, and the two separating pieces 6, 6 of the outer film 2 and one short side portion 10 of the inner film 3, which overlaps this portion, are then bonded by any means such as heat fusion. And the bonding margins 9 of the outer film 2 are bonded to each other by heat fusion or the like, so that the outer periphery is substantially sealed, and the packaging rice balls 1
Can be manufactured.

Next, FIG. 5 shows an example of a manufacturing process of the packaged rice ball 1. The processing table 11 forms a step 12 substantially equal to the thickness of the rice 5 in the middle of the upper surface large enough to place the outer film 2 thereon, and forms an upper step 13 and a lower step 14.

As described above, according to the present invention, laver is layered on the inner side of the outer film, the inner film is layered on the inner side, and the short side of the layer is overlapped on the separated piece of the outer film. Then, put the rice ball on the inner surface of this inner film, fold the outer film together with the inner film and overlap it on the rice ball, and then, on top of that, the separated piece part of the outer film and the inner film part that overlaps this Can be manufactured by heat-sealing, etc., and at the same time, the bonding allowances of the outer films can be manufactured by heat-sealing, etc. to produce a packaging rice ball.

Also, laver is layered on the inner side of the outer film, a substantially half surface of the inner film is layered on the inner side, and the short side of the layer is overlapped on the separated piece of the outer film. Place the rice ball on the inner surface, fold the inner film back on the rice ball, fold the outer film in half on it, then separate the outer film piece and the inner film part that overlaps this Are bonded by heat fusion or the like, and at the same time, the bonding margins of the outer films are bonded by heat fusion or the like to produce a packaged rice ball.

Therefore, it is possible to easily and reliably manufacture a wrapping rice ball without folding both corners of the wrapping film and attaching a label to the fold portion, and furthermore, the separating means can be formed by folding the outer film into two. Since the label is provided along the side portion, a desired label for display can be stuck on a portion other than the separating means, and separation by the separating means is not hindered by the label and can be performed extremely smoothly. . Also, when the inner and outer films are bonded by heat fusion or the like, if the air in the outer film is extracted and manufactured, the inner and outer films and laver will not be stably displaced in a substantially sealed state, and together with prevention of deterioration, It will be preferable.

Further, the wrapping film is wrapped with the rice balls in a state of being simply folded without being folded many times. In addition, in order to obtain the rice balls in the state of laver, together with the separated pieces separated by the separating means, Since it can be done simply by pulling out the inner film, the nori sandwiched between the inner and outer fills is not broken, and a complete nori rolled rice ball can be easily obtained.
