BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaged rice ball formed by packaging triangular rice balls in a state separated from laver.

[0002]

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 overlapped with 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 into pieces 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 nori is packaged.

However, when packing rice with the above-mentioned package, the package is folded in two along one side of the triangular rice in the lateral direction at the center, and furthermore, both sides projecting in a triangle are formed. 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 likely to be 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. Also, of the two corners folded, the front end of the folded part folded inward beyond the dividing line is spot-sealed together with the upper folded part, and this spot seal part is simultaneously divided when divided by 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.

[0004]

However, in the above-mentioned notch structure, although the cutting itself is easy, both corners are reduced by the notches, so that the coating is insufficient and the coating is partially exposed or cut. 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 that adheres to the outside does not hold down the action so as to prevent that action, resulting in the inhibition of simple cutting. There was a risk. 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 risk that simple division is unlikely to occur.

[0005] The present invention solves the above-mentioned problems, and is a package in which laver is sandwiched between inner and outer films. Can be separated into two portions and separated, and a rice ball in a laver state can be obtained.

[0006]

In order to solve the above-mentioned problem, the present invention is to provide a small-sized seaweed inside an outer film formed by a dividing means which can be divided in a longitudinal direction of a central portion of a rectangular body. Overlap, further, on the inner side, two inner films whose widths are appropriately wider than the half-split shape obtained by dividing the width of the outer film by half are aligned with the outer peripheral edge of the outer film, and the central portions overlap each other. In this way, the inner and outer films are adhered along the outer peripheral edge of the outer film by heat sealing or the like, and a diagonal slit is formed on the long side of only one corner of both short width corners. Using a film, wrap the rice in a fold in such a way that one side of the triangular shape of the rice is in the center of the film and wrap it in a folded shape so that one side of the packaging film is along the rice. First on While folding one corner side not having the slit, the tip portion is folded outward so that the folded portion does not overlap or only slightly overlaps the dividing line formed by the dividing means, and further slits thereon The other corner side having a fold is folded so that the slit part is located on the dividing line, and each folded part is separately stopped by a heat seal or the like on the film surface of the half part which has already been folded in the middle part on each lower side. It is characterized in that it has a configuration in which a label is attached over both outer sides of the folded corners to form a packaging rice ball. The label has a plurality of slits formed in parallel at least on the side of the tearing side, and is preferably formed of a material such as paper that is easily torn.

[0007]

[Function] Since both folds are fixed at the root side where the fold is made rather than on the dividing line, the leading end side is a free end beyond the dividing line, and the lower folded portion does not substantially exceed the dividing line. At the same time, a slit is formed in the upper folded portion, so that the division is performed smoothly. Since the outer folded portion has no notch, the coating can be sufficiently performed.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the package 1 used in the present invention is a rectangular biaxially stretched arbitrary synthetic resin film, and a cut tape 3 (a narrow tape for cutting) 3 as a dividing means in the central longitudinal direction. Inside the outer film 2 provided with
A laver 4 smaller than the outer film 2 is layered thereon, and further inside, a half-split shape which is an arbitrary synthetic resin film of the same material or a different material as the outer film 2 and which is a half of the short width of the outer film 2 Also, the two inner films 5, 6 each having an appropriately wide short width are aligned with the left and right halves of the outer film 2 at the outer peripheral edges, and the inner side portions of the inner films 5, 6 are overlapped with each other at the center. As shown in FIG. 2, the inner and outer films 2, 5, and 6 are heat-sealed 7 along the outer peripheral edge of the outer film 2, and as shown in FIGS. In the longitudinal side of one corner (the other corner 1b) of No. 5, a slit 8 of an appropriate length is formed in parallel, preferably several in parallel, with its inside gradually inclined in the direction of the shorter side. And both sides of one end or both ends of the cut tape 3 Ri tear is made to form a guide for the slit 9. It is assumed that the slit 8 is formed in a position and a direction that substantially match the dividing line when the rice ball 10 is wrapped in the package 1.

First, as shown in FIG. 2, the package 1 having the above-described structure is used to place a triangular rice ball 10 on the inside of one half of the package, that is, on the inner film 5, so that one side thereof is along the short side of the central portion. As shown in FIG. 3, the package 1 is wrapped in a folded shape as shown in FIG. 3, and one half of the package, that is, the inner film 6 side is brought into close contact 11 along the side of the rice ball, and then, as shown in FIG. First, the corner 1a where the slit 8 is not formed
Is folded back and its tip is turned outward so that the folded portion does not overlap or slightly overlaps on the cut tape 3. Further, as shown in FIG. 5, another corner having a slit 8 thereon is provided. The side 1b is folded, and the slit 8 is positioned on the cut tape 3. Each folded portion is folded more than the cut tape 3 and a heat is applied to the film surface of the one-half portion which has been folded under the root side portion. The fastenings 12, 12 are separately applied by a seal or the like, and a label 13 is attached to the outside of both folded corners to form a packaging rice ball.

The label 13 is made of paper of appropriate size to cover the folded portion, and a plurality of slits are finely juxtaposed on its lower side (the side on the cutting start side by the cut tape 3) or upper and lower sides. It is preferable that the cutting by the cut tape 3 can be performed more smoothly regardless of the displacement due to the attachment. A desired display can be applied to the surface. Note that the above description does not limit the operation procedure in the manufacturing process, so that the order can be changed in the process design or can be performed simultaneously if the order is possible.

In the case of a packaged rice ball having the above structure, when eating, first, one end of the cut tape 3 is pulled to tear the entire outer film 2 from the side where both corners are not folded further and beyond the folded part. In the folded portion, the corner 1a, which is folded downward, is folded back at the tip, and the tip does not substantially exceed the cut tape 3, so that the path of the cut tape 3 is obstructed. The other corner side 1b folded upward without any
Although the upper part is covered, the slit 8 formed in the dividing direction makes it extremely easy to divide by the cut tape 3, and the front end is not fixed by heat sealing or the like and becomes a free end. As a result, the cut tape 3 is easily cut by tearing, or if the leading end is turned up, the cut tape 3 is opened even in the middle of cutting, so that the cutting action is not hindered. Since the label 13 is divided from the lower side and is already divided just before reaching the other corner side 1b, no trouble occurs. Moreover, the other corner side 1b can be covered with a sufficient overlap margin.

In the above construction, the outer film 2 and the inner films 5 and 6 are different films, but a film portion is extended on both outer sides of the longitudinal side of the outer film 2 and this film portion is folded back. It may be formed by forming the inner films 5 and 6 or the like. 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 the outer film 2 can be easily divided into two parts.
For example, in order to easily tear the central portion along the direction of the outer film 2, only a slit guide slit may be formed, or a guide slit may be formed and a cut tape may be partially provided. For example, a break may be provided. Although not shown, the central overlap portions of the inner films 5 and 6 are such that the edges of the two films are inverted (inside of the rice balls) at the overlap portions.
The film may be folded back, or only the film portion polymerized on the inside may be folded inside 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 7 may be performed on the entire short side, or may be performed on only the other portion except the end portion of the cut tape 3 and the center portion where the guide slit 9 is formed. Further, the slit 8 is formed outside the linear cut,
It may be a V-shaped single notch or a V-shaped repetitive continuous notch, and the shape of the present invention is not limited as long as it becomes a slit. In addition, the slit 8 is formed only at one corner in the short direction, and in the figure, an example in which it is formed only at one end in the long direction is shown. The film may be formed in a point symmetric shape. By doing so, the package 1 has no directionality, so that the package 1 can be set in any direction in the longitudinal direction at the time of packaging, which is simpler in operation.

[0013]

As described above, according to the present invention, the package 1 can be manufactured by sequentially performing the work of stacking the flat objects, the slit forming of the flat objects, and the heat sealing operation. The seaweed 4 can be individually wrapped so as not to cause moisture, and the separate wrapping of the rice ball 10 is simple, since it is only necessary to fold each part and fasten both corners 1a and 1b, At this time, the corner 1a to be folded downward has its tip folded outward so that it does not substantially overlap on the dividing line, and the other corner 1b, which is folded upward, overlaps the whole as it is, so that there is room for the coating. In addition, there is no possibility that packaging defects such as partial exposure of the package will occur, and therefore, even if there is a slight shift in the position, packaging can be performed simply and reliably. Moreover, when the outer film 2 is divided by the dividing means to open the packaged state while the packaged state is opened, the corner 1a folded downward is folded back and folded upward. The slit 8 is formed in the other corner side 1b and the leading end side is also a free end, so that it does not hinder the dividing action, and furthermore, there is no folded portion on the lower side and the upper side is folded. Since the slit 8 is formed in the corner side 1b, the corner side 1b can be easily opened and the division can be performed smoothly. Even if the label 13 is stuck,
As a result, there is no difficulty in dividing and opening.
