る。2. Description of the Related Art Conventionally, nigiri rice and laver are packaged in a separated state so that the laver is hygienic and the laver is protected in a fresh state, and the laver is combined with the laver when eating, so that the laver can be eaten as it is. Packaging rice balls have been proposed in various configurations. Among them, as the simplest package, and the operation at the time of eating is simple, a cutting means such as forming a cut tape in the longitudinal direction of the central portion of the outer film or forming a tear guide portion of the directional film. Is placed on the inside, a small size laver is layered on the inside, and two inner films with a shape slightly larger than the half-shape of the outer film are fitted on the inside, and the outer periphery is matched with the outer film, and the central part is superimposed on each other. There is a package having a configuration in which the inner and outer films are heat-sealed along the outer peripheral edge of the outer film. When wrapping rice in this package, when eating, first, the outer film is divided into left and right by the dividing means formed in the center of the outer film, and the inner film is formed by polymerizing two films at the center. As a result, the package is divided from the beginning, so that the whole package is divided into two parts, and one half can be pulled out to the left and right, respectively, to obtain a rice ball in a state in which the laver is packaged.

The corners are wrapped over rice and the labels are pasted on this overlapping part.Both corners are folded on the dividing means in a double state, and the label is pasted on it. For this reason, the division by the division means is caught at the above-mentioned folded portion, and it is easy to easily and accurately perform the division. Attempting to forcibly divide the rice will result in the rice being strongly tightened, which may cause the rice to lose its shape and may even be difficult to open. For this reason, a notch structure in which both corners are cut so as not to overlap the two corners has been proposed. This is based on the idea that the division is not hindered without the overlapping portion. In addition, of the two corners folded, the front end beyond the dividing line of the folded part folded inward is spot-sealed together with the upper folded part, and this spot seal part is simultaneously divided when dividing by the dividing means. Because of the idea that if the inward folded part is released, one half can be pulled out as it is, there is also a kerf structure in which a kerf is formed at a position on the dividing line at the edge of the inward fold. Proposed. This is based on the idea that the cutting can be easily performed even at the overlapping portion by the cut groove.

それがあった。However, in the above-mentioned notch structure, although the cutting itself is easy, both corners are reduced by the notch, so that the coating becomes insufficient and the coating is partially exposed or notched. Because there is a part and the insertion fee is reduced,
The misalignment between the laver and the film, the package and the rice ball, or the misalignment of the folding when packaging the rice in the package is likely to occur and become more noticeable. Further, since the cut-off portions restrict the portions that can be fastened at both folded portions to a smaller extent, the fastening may be insufficient. Further, in the above-described kerf structure, since the other corner portion folds outside the inward fold portion where the kerf is formed, when the label is fixed on the fold portion, In contrast to the action of cutting the tip of the inner folded part using the kerf, the folded part closely contacted to the outside has the effect of pressing down so as to prevent the action, which results in the hindrance of simple cutting. There was a fear. In the above structure, a cut groove similar to the above can also be formed in the outwardly folded portion, but it is difficult to pack the cut groove so as to match it, and the folded front ends of both corners are obliquely opposite. Since it is folded to face, the tearing direction is diagonally opposite to the direction of the film, resulting in different directions from the dividing linear direction of the dividing means,
In the state where the label is stuck, there is a possibility that simple division is difficult.

In this case, the folded portion does not need to be heat-sealed. The cut tape 3 is not particularly limited to the cut tape 3 as long as it is configured to easily divide the outer film 2 into two parts. For example, a slicing guide is provided so that the center part can be easily torn along the direction of the outer film 2. Only slits may be formed, or a guide slit may be formed and cut tape may be partially provided, or intermittent cuts such as perforations may be provided. Although not shown, the central overlapping portions of the inner films 5 and 6 may have a configuration in which the edges of both films are folded inward (inside of rice) on the overlapping portions in an inverted manner. Only the film portion that has been turned may be turned inside out in an inverted manner. The superposed portions of the inner films 5 and 6 can be lightly heat-sealed so that they can be easily separated. Further, the heat sealing portion 7 may be applied to the entire short side, or may be sealed only at other portions except the end of the cut tape 3.

ことがない。As described above, according to the present invention, the packaging film 1 can be manufactured by sequentially performing the work of stacking the flat objects, the operation of cutting out the flat objects, and the operation of heat sealing. It is simple and can be packaged independently so that the seaweed 4 is less likely to be moist. Further, the separation and packaging of the rice ball 20 is simple because it is only necessary to fold each part and fasten the corners 8 and 14 side. In this case, the corner 8 folded downward is provided with a notch with a sharp projection. Since the corners 8 are formed, the corners 8 are not easily caught by the cut tape 3 and are covered beyond the cut tape 3, so that the division is smooth and the covering is sufficiently performed. Further, since the square notch 18 is formed in the corner 14 which is folded upward, the smoothness of division is not impaired.

分断、開封に支障は全く生じない。That is, while the covering is in a sufficiently wrapped state, the corner 8 side folded downward is a notch 13 with a sharp projection and the leading end side is a free end, and the corner 14 side folded upward is closed. Since the front end side is a free end, it slightly crosses over the dividing line, and the cutout tape 3 is widely opened by the rectangular notch 18, so that the dividing can be performed smoothly. Even if the label 22 is attached,
There is no hindrance to separation and opening.
