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.

ぎりを得るのが煩わしいものであった。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.

り込んでラベルを貼りつけた包装おにぎりがある。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.

締めて型を崩しやすいといった欠点があった。[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.

装フィルムで包装された包装おにぎりがある。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.

た。このことから、分断手段上への重なり部分を少なく
し、分断を阻害しないようにとの思想により、互いに重
ならないように両隅部を斜めに切欠くなどして、隅部に
切欠部を形成したものが既に提案されている。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 nigiri rice is folded in half 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. However, the cutting by the cutting means is caught at the overlapping portion, and it is difficult to perform the simple and accurate cutting. 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.

可能部分が少なく限定され、ラベルによる止着が不十分
となるおそれがあった。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.

った。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.
