Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a variety of packaged rice balls, in which nigiri rice and seaweed are packaged separately, are hygienic, and the seaweed is fresh, and when eating, the seaweed is combined with the nigiri rice to obtain rice ball wrapped with seaweed Is proposed in the configuration.
Among these, laver that is smaller than the outer shape of the rectangular outer film is stacked on the inside of the outer film, and two inner films having a width slightly larger than the width divided into two in the longitudinal direction of the outer film are further stacked on the inside. A part of the inner film of the outer film is overlapped with each other, the outer peripheral edge part is overlapped with the outer peripheral edge part of the outer film, and the inner and outer film is adhered along the outer peripheral part. There is a wrapping rice ball on which nigiri rice is placed, the other half part is folded along it, and the triangular protruding parts of the inner and outer films are folded and a label is stuck on it.

When eating, the packaging rice balls are peeled off the label, the packaging film is opened, and the rice nigiri rice is placed on one half of the inner film while the other half of the inner film is peeled off to expose the exposed seaweed. Fold it on top, and this time, put the rice ball back on the other half of the inner film with the seaweed down, peel off the inner film on the one half side and fold the seaweed on the rice, then roll the rice ball Is what you get. However, when the seaweed is combined with this packaged rice ball, the rice and seaweed may be exposed from the inner film and become unsanitary. Moreover, the rice ball is placed again on the inner film to combine the seaweed. , Nigiri rice easily slipped off from the packaging film, and it was troublesome to obtain seaweed rice balls.

As a solution to these drawbacks, a triangular conical rice ball is formed in a conical shape so as to substantially follow the outer shape of the rice.
An inner film of this packaging film is formed by using a packaging film in which seaweed is interposed between an outer film formed with perforations capable of separating the leading end portion to form a small hole and an inner film having substantially the same shape. There is a wrapping rice ball in which rice balls are inserted inside, the opening is folded and a label is attached.

[0005] In this packaging rice ball, if the perforation is torn and the tip is removed, the tip of the inner film is exposed, and if the label is peeled off, the folded portion is opened, so if the tip is pulled and the inner film is pulled out. Nori wrapped rice balls can be obtained, and the operation when eating is simple and hygienic. However, since the inner film tends to stick around the rice ball and it must be pulled out from the small hole in the outer film, it cannot be pulled out into the smooth, so if you try to pull it out forcibly, squeeze the rice ball firmly. It had the drawback that it was easy to lose its shape.

As a solution to this drawback, a small piece of seaweed is overlaid on the inside of an outer film having a cutting means such as a cut tape formed in the longitudinal direction of the central portion of the rectangular body, and a short inside is formed. Two sheets whose width is slightly wider than the width of the outer film divided into two, the inner film, the outer film is aligned with the outer peripheral edge and overlapped with each other so that the central portion is superposed,
There is a packaging rice ball wrapped with a packaging film obtained by heat-sealing the inner and outer films along the outer peripheral edge of the outer film.

In this packaging rice ball, if the outer film is divided into left and right parts by the dividing means, the inner film is a divided type in which two films are polymerized in the central portion, so that the entire packaging film is divided into two parts, By pulling the halves to the left and right, you can easily combine the seaweed with the nigiri rice to get the rice ball wrapped with seaweed. However, one side of the nigiri rice is folded in two along the lateral direction of the central part, and both corners protruding in a triangular shape are sequentially folded on the nigiri rice, and a label is attached to this overlapping part. Therefore, the dividing by the dividing means is caught at the overlapping portion, and it is difficult to perform the simple and accurate dividing. Based on this, we have formed a notch in the corner by diagonally notching both corners so that they do not overlap each other by reducing the overlapping part on the cutting means and not disturbing the cutting. What has been done has already been proposed.

[0008]

However, the above-mentioned cutouts are preferable in that the cutting itself is facilitated because the overlapping with the cutting means is reduced, but both corners have cutouts. Since it is reduced by the amount of the portion, the nigiri rice is not fully covered and partially exposed, or
As the overlap is reduced, the number of folded portions is reduced, so that the portion that can be fastened is limited, and there is a possibility that fastening by the label is insufficient.

On the other hand, regardless of whether or not the notch is formed, in order to fix both folding parts, the root side part of the folding part is heat-sealed and fixed, 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 a cutting tape, the cutting tape will be cut during the cutting, or if you try to forcibly divide the nigiri rice, the nigiri rice will lose its shape, resulting in smooth separation. It was sometimes difficult to do. In addition, even after cutting, since the root side part of the fold is still heat-sealed, it is difficult to smoothly cut out when cutting one half left and right, and the seaweed part sandwiched between the folds is torn off. There were problems such as being easy.

According to the present invention, the above-mentioned problems are caused by folding the packaging film in multiple layers, and further, by packaging a label on the breaking means for opening, the packaging rice ball is packaged.
The manufacturing method and the packaging film were found to have problems, and in order to solve the problem, it was made by fundamentally improving the structure of the packaging rice ball and its manufacturing method, and the structure of the packaging film. The purpose is to fold nigiri rice easily and surely by folding the inner and outer films with the seaweed in between, and when you eat it after production, you can easily open and easily open it. It is intended to provide a packaged rice ball and a method for producing the same, and a packaging film that can provide a seaweed rice ball.

[0011]

In order to solve the above-mentioned problems, the present invention provides a separating means so that a two-fold side portion in a state of being folded into two can be formed into a separating piece with an appropriate width, and , The inner surface of the outer film that uses the other outer peripheral edge portion as an adhesion margin, and inward from the adhesion margin

Is folded back in two and the separated piece part of the outer film and the inner film part that overlaps this part are bonded by heat fusion or the like, and at the same time, the bonding margins of the outer film are bonded by heat fusion or the like. It is then wrapped in rice balls.

In addition, when the inner film is overlaid, a substantially half surface portion of the inner film is overlaid on one inner surface of the seaweed, and the side portion adjacent to the two-fold side of the inner film is the separation piece. The inner film is placed on the inside to form a wrapping film, and the nigiri rice is placed on the inside of this inner film portion and the inner film is folded back in half to cover the nigiri rice.Furthermore, the outer film is folded back along with seaweed and overlapped on the outside. Together, the separated film part of the outer film and the inner film part that overlaps this part are bonded by heat fusion,
At the same time, a packaging rice ball having a structure in which the bonding margins of the outer film are bonded to each other by heat fusion or the like can be used. The above packaging rice ball preferably has a structure in which air is removed from the packaging film when the outer peripheral edge portion of the outer film is bonded by heat fusion or the like.

Further, according to the present invention, the separating means is provided so that the two-fold side portion in the state of being folded in two can be formed as a separating piece with an appropriate width, and the other outer peripheral edge portion is used as an adhesive margin. On the inner surface of the film, inside the adhesion margin, laver seaweed on both sides of the separating piece, and stack the inner film on the inner surface of this seaweed to form a packaging film. Place the nigiri rice on the inside, fold the packaging film back in half so as to cover the nigiri rice, and bond the separating piece part of the outer film and the inner film part overlapping this part by heat fusion or the like, and at the same time, the outer film Is characterized by a method of manufacturing a packaging rice ball having a constitution in which the bonding margins of (1) are bonded by heat fusion or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, the packaging rice ball 1 according to the present invention is made into a packaging film by interposing the seaweed 4 between the outer film 2 and the inner film 3 and using this packaging film, the rice ball 5 Is packaged.

The outer film 2 is a rectangular film made of an arbitrary synthetic resin and is stretched in the lateral direction, preferably biaxially stretched, and the longitudinal direction thereof is folded in two. In this state, the triangular sushi rice 5 is sized so as to be able to be packed, and this portion is separated along the two-fold side portion in the state of being folded in two, and the perforation 7 as a separating means is provided as a separating piece, and A notch 8 for providing a tear guide is provided at both ends, and an outer peripheral edge portion other than the portion where the notch 8 is formed is used as an adhesion margin (allowable clearance width) 9.

The inner film 3 is made of a synthetic resin, preferably a polyethylene terephthalate (PET) film, which has been subjected to a silicon treatment, or a matte-treated matte film. It is a rectangular film made of synthetic resin or the like whose surface is processed so that the frictional resistance becomes small) and is smaller than the outer shape of the outer film 2.
The seaweed 4 is of a small size so that it can be separately stacked on both sides of the separation piece 6 inward of the adhesion margin 9 of the outer film 2.

Using the inner and outer films 2, 3 and seaweed 4, the packaging rice ball 1 of the present invention can be manufactured as follows. First, on both sides of the separation piece 6 on the inner surface of the outer film 2, seaweed 4 is overlaid inward of the adhesive margin 9, and the inner film 3 is placed inside the seaweed 4.
On top of this, and nigiri rice 5 is placed on this inner film 3 (FIG. 4).

Next, the outer film 2 is folded back in half along with the inner film 3 at the separating piece 6 portion and folded on the opposite side of the nigiri rice 5, and then the separating piece 6 of the outer film 2 is folded.
The portion and the portion of the inner film 3 overlapping this portion are adhered together by an arbitrary means such as heat fusion and the outer film 2
It is possible to manufacture the packaging rice ball 1 by bonding the bonding margins 9 of No. 1 to each other by heat fusion or the like, and making the outer circumference substantially sealed.

Next, FIG. 5 shows an example of a manufacturing process of the packaging rice ball 1. In the processing table 10, a step 11 having a thickness substantially equal to the thickness of the nigiri rice 5 is formed at an intermediate portion of an upper surface having a size large enough to mount the outer film 2, and an upper step surface 12 and a lower step surface 13 are formed.
And are formed.

First, the inner and outer films 2 and 3 are overlapped with the seaweed 4 interposed therebetween, and the upper and lower step surfaces 12 of the processing table 10 are
Place it so that it straddles 13. Next, the nigiri rice 5 is placed on the inner and outer films 2 and 3 portions of the lower surface 13 (FIG. 5A), and the inner and outer films 2 and 3 portions on the upper surface 12 are squeezed by the work arm (not shown). If it is turned upside down (B in the same figure), and then a separate heat seal press (not shown) is used to adhere the adhesive margin 9 of the folded outer film 2 by heat fusion or the like, the packing rice ball 1 Can be manufactured (FIG. 7C).

Further, in this packaging rice ball 1, when the packaging is completed, the corners of the inner and outer films 2 and 3 project in a triangular shape from the rice ball 5 to form voids in the film, so that the bonding margins 9 are bonded together. When the outer film 2 is made into a vacuum pack while removing air, the nigiri rice 5 and the inner and outer films 2, 3 and seaweed 4 will not be stably displaced in a substantially sealed state, and combined with prevention of deterioration. Will be even more preferable. In addition, the rectangular flat surface portion 14 of the finished packaging rice ball 1 may be hung on the perforations 7, but preferably the manufacturing date,
A label 15 having a desired display such as a product name can be attached.

When eating the packed rice ball having the above structure,

Perforation 2 as a separating means that separates this part along the two-fold side part to form a separating piece 21.
2 is provided, and cutouts 23 for guiding tearing are provided at both ends thereof, and an outer peripheral edge portion except a portion where the cutout 23 is formed is used as a bonding margin (adhesive allowance width) 24.

The inner film 19 is smaller than the outer film 18 and is preferably made of an arbitrary synthetic resin film.
The seaweed 20 is made of a synthetic resin film that has been processed in the same manner as the inner film 3 described above. It is made up of small pieces that can be stacked.

With this packaging rice ball 17, when eating, cut the perforations 19 and pull the separating piece 18 outward to obtain the seaweed rice ball as in the case of the packaging film 1. You can That is, also in this case, the tearing is performed extremely smoothly without being obstructed by the label or the like, and if the inner film 23 is pulled out together with the separating piece 18, the seaweed rolled rice ball with the two seaweeds 24 can be easily obtained. . Also, the inner and outer films 2
In the state where 2 and 23 are overlapped, the separated piece portion of the outer film 22 and the portion of the inner film 23 that is overlapped with the separated piece portion are adhered by heat fusion or the like to form a packaging film in advance, which is used. Then, the packed rice ball 17 can be produced.

In addition to this, as the inner and outer films, FIG.
As shown in Fig. 7, the corners of the rectangular body may be cut out so that the short sides are formed into an arc shape, and the means for separating the two folded side portions is a cut tape (thin tape for cutting). 25
And an outer film 27 having slit guide slits 26 formed on both ends thereof and an inner film 28 smaller than the outer film 27.
It is also possible to produce a packaged rice ball in the same manner as the above packaged rice ball 1 or 17 using.

The shape of the outer film is not limited to the above-mentioned embodiment, and may be any shape as long as nigiri rice can be packaged. The inner film and seaweed correspond to this outer film. It can have any shape. Further, the separating means may be the above-mentioned perforations, cut tapes, or other separable means or a film structure, and the forming line of the separating means can also be set to a curve or any other.

As a further different embodiment, as shown in FIG. 10, on the both sides of the separating piece 6 on the inner surface of the outer film 2, the seaweed 4 is placed inward of the adhesive margin 9, and The inner half of the inner film 3 is overlapped on the inner seaweed 4 on one side thereof, and the adjacent side portion 31 adjacent to the double-folded side of the inner film 3 is overlapped with the separation piece 6 portion. The nigiri rice 5 is placed on the inner side of this inner film 3 portion, the inner film 3 is folded back in half so as to cover the nigiri rice 5, and the outer film 2 is folded back together with the seaweed 4 on the outer side thereof and overlapped on the nigiri rice 5. In order to integrally bond the separated piece 6 part of the outer film 2 and the inner film 3 part overlapping this part by heat fusion or the like, and at the same time, bond the bonding margins 9 of the outer film 2 by heat fusion or the like. Ri, it is also possible to manufacture the packaging rice balls.

Also in this packaging rice ball, in the state where the inner and outer films are stacked, the separated piece portion of the outer film and the inner film portion which is overlaid thereon are adhered by heat fusion or the like to form a packaging film in advance. It can also be manufactured by using this. Also, the packed rice ball produced in this way is similar to the packed rice ball 1 above,
The operation when eating is simple and easy, and you can easily obtain seaweed rice balls. Of course, when the bonding margins 9 are bonded to each other by heat fusion or the like, it is more preferable if the air in the outer film is removed and the outer film is vacuumed and packaged.

In the embodiment shown above, as shown in FIG.
When stacking the inner and outer films as shown in FIG. 8 and FIG. 9, when the inner and outer films are placed on the short width portion of the inner film that overlaps the separating piece portion of the outer film so that one triangular side surface of the nigiri rice stands upright. The film is folded together with seaweed from both sides, and the separated piece part of the outer film and the inner film part that overlaps this part are integrally bonded by heat fusion, etc. At the same time, the bonding margins of the outer film are bonded by heat fusion etc. It is also possible to manufacture packed rice balls.
