2. Description of the Related Art Recently, in addition to sushi specialty stores, it is possible to easily purchase nigiri sushi at supermarkets and department stores. However, since the nigiri sushi displayed in supermarkets and department stores is a platter-shaped nigiri sushi (A) in which a certain type of nigiri sushi is packed in a folding box as shown in FIG. It was not possible to purchase any kind of seeds. However, in recent years, in light of this situation, the packaging of individually wrapped individually wrapped nigiri sushi with an optional bed so that consumers can select the type of bed to purchase. Nigiri sushi has come to be created.

[0003]

However, as shown in FIG. 14, the individually packaged nigiri sushi (B) is a nigiri sushi prepared by placing an arbitrary seed on a transparent film from (c). There is a problem that it is very troublesome to disassemble the package when it is eaten because it is a package of Nigiri sushi, which is relatively small, since it is only sealed and adhered or fusion-sealed. .

[0004]

According to the present invention, a nigiri sushi on which an arbitrary bed is placed is stored in a package formed of a transparent film, and the package contains the stored nigiri sushi. By providing a individually wrapped nigiri sushi characterized in that a strip-shaped tear body is formed over the entire width of the packaging periphery, the above-mentioned conventional problems are solved.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The structure of the individually packaged nigiri sushi and the method for mass producing individually packaged nigiri sushi according to the present invention will be described in detail below with reference to the drawings. First, the structure of the individually wrapped nigiri sushi of the present invention will be described in detail. FIG. 1 is an external view showing an embodiment of the individually wrapped nigiri sushi of the present invention. As shown in the figure, in the present invention, nigiri sushi (2) on which an arbitrary bed is placed is housed inside a package (3) formed of a transparent film (30). In the package (3), a strip-shaped tear body (4) is formed in the substantially central portion over the entire width of the package surrounding the stored Nigiri sushi. The strip-shaped tearing body (4) is formed such that the tip portion (41) thereof extends from the surface of the packaging body (3). Further, in the present invention, as shown in FIG. 2, notches (5) are formed in the tearing direction of the tear body (4) on both sides of the tip portion (41) of the band-shaped tear body (4) of the packaging body (3). It may have been done.

In the individually-wrapped nigiri sushi (1) having the above-mentioned structure, the tearing body (4) and the tip portion (40) are edible when being eaten.
When is pulled, the tear body (4) is stripped from the packaging body (3) in a strip shape, and the packaging by the packaging body (3) is disassembled. That is, as shown in FIG. 3, the packaging body (3) is a tear body (4).
The nigiri sushi (2) stored inside is exposed to about half. Therefore, when edible, when the half face of the package (3) is picked with a finger and the tearing body (4) is peeled off with the other finger, half the nigiri sushi (2) is exposed. ) You can eat nigiri sushi without touching it, and even such a small package can be easily and easily disassembled.

FIGS. 4 to 9 are explanatory views showing an example of production of individually wrapped nigiri sushi (1) according to the present invention. In the individually wrapped nigiri sushi (1) of the present invention, first, a rectangular transparent film (30) as shown in FIG. 4 is used. Especially when the transparent film (30) is used, the nigiri sushi (2) housed inside can be seen through so that consumers can select and purchase their favorite Negi nigiri sushi. It is because Further, a strip-shaped tear body (4) is provided over the entire width in the vicinity of the substantially central portion of the rectangular transparent film (30). The tear body (4) is preferably colored so as to serve as a mark when tearing. Further, in this example, the transparent film (3
The notch (5) is formed in both sides of the tip portion (41) of the tear body (4) in the peeling direction of the tear body (4).

Nigiri sushi (2) is placed on the upper surface of the transparent film (30) having the above-mentioned structure. The placing direction is preferably such that the longitudinal direction of the tearable body (4) and the longitudinal direction of the nigiri sushi (2) are orthogonal to each other. Further, as the placement position of the nigiri sushi (2), it is preferable to place the nigiri sushi at substantially the center of the tearable body (4). In other words, by placing the nigiri sushi (2) in this way, the nigiri sushi package (1) can be disassembled while being held with a finger at the time of eating, and the nigiri sushi (2) This is because it is possible to expose the nigiri sushi (2) in a state where about half is wrapped with the transparent film (30), which is preferable.

After placing the nigiri sushi (2) on the transparent film (30) as shown in FIG. 5, as shown in FIG.
The nigiri sushi (2) is wrapped in the short side direction with the transparent film (30). In this state, the portion (301) where the transparent films (30) overlap each other is appropriately fixed by any means such as spot welding or adhesion. At this time, it is necessary to fix at least the vicinity of both sides of the tear body (4). That is, when the package is disassembled by the tearable body (4) during eating, if the vicinity of the tearable body (4) is insufficiently fixed, the tearable body (4) can be easily and favorably separated from the package (3). Because you cannot do it. Next, as shown in FIG. 7, the transparent film (30) is squeezed together in the longitudinal direction of the sushi (2) and the tip portion (30a) is folded back to the upper surface of the sushi (2) as shown in FIG. Then fix it again by spot welding. Further, when the other end (30b) of the transparent film (30) is similarly folded back, welded and fixed, the individually wrapped nigiri sushi (1) as shown in FIG. 9 is formed.

The individually-wrapped nigiri sushi (1) thus formed is edible, and the tip portion (41) of the tearable body (4) is edible.
The package (3) by pinching and pulling the
Is easily divided into about half, and about half of the nigiri sushi (2) inside is exposed from the package (3). Moreover, since notches (5) are formed in the tearing direction of the tearing body (4) on both sides of the tip end portion (41) of the tearing body (4) of the transparent film (30), the tearing body ( 4) can be satisfactorily separated from the transparent film (30), and there is no fear that the package (3) will be disassembled improperly. Therefore, the nigiri sushi (2) can be easily exposed and eaten from the package (3) without touching it directly.

As shown in FIG. 10, various kinds of nigiri sushi (1) individually packaged by such a transparent film (30) are manufactured and placed on a display stand (Y) of a supermarket or a department store. It is purchased by a consumer by putting an appropriate item in a container (Z) or the like. Therefore, unlike conventional assorted sushi, it is possible to freely select and purchase any desired sushi instead of a preset type of nigiri sushi.

Next, the structure of the mass-production method of individually wrapped nigiri sushi according to the present invention will be described in detail. In the mass production method of the present invention, the sushi rice (20) of nigiri sushi formed into a predetermined shape is individually stored in a storage container (6) which is recessed in vertical and horizontal grids as shown in FIG. Keep it. In the illustrated embodiment, the accommodating container (6) is provided with a plurality of accommodating portions (61) which are recessed in the shape of vertical and horizontal grids and which are formed in a tapered shape from the upper side along the inner bottom surface. )
The required number of grooves (62) are provided on the inner wall of the so that the contained sushi rice can be easily taken out. The storage container (6) in which the sushi rice (20) is stored is shown in FIG.
As shown in 2, the sushi rice feeding mechanism (7) conveys the rice. This sushi rice feeding mechanism (7) may be either a device for continuously carrying it or a device for intermittently driving it at a predetermined pitch. In the case of intermittent driving, for example, a row of sushi rice (2
When 0) is taken out, an apparatus set to deliver a predetermined length is preferably used.

The sushi rice (20) conveyed by the sushi rice feeding mechanism (7) is then grasped by the first arm (8) while maintaining its shape, and the sushi preparation line (9) is obtained. They are arranged in a line on the top. At this time, sushi rice (20)
The sushi rice (20) for one row in the storage container (6) can be grasped one by one by the first arm (8) and placed on the sushi preparation line (9) or by a plurality of arms.
Either one may be seized individually at a time and placed on the sushi preparation line (9). The sushi preparation line (9) is sequentially advanced by a belt conveyor (not shown) to convey the placed sushi rice (20) to the next step. At the time of this transportation, first, the wasabi (201) was applied on the upper surface of the sushi rice (20), and then the desired (20)
2) is placed and nigiri sushi (2) is prepared. The prepared nigiri sushi (2) is gripped by the second arm (10) while maintaining its shape, and placed on the next automatic or semi-automatic packaging table (11).

A transparent film (30) is placed on the packaging table (11) in advance, and the transparent film (30) is placed.
Place the nigiri sushi (2). Here, as the transparent film, a film having a rectangular shape as shown in FIG. 4 and having a tear body (4) formed at the center is used. The nigiri sushi (2) is placed so that its longitudinal direction is orthogonal to the longitudinal direction of the tearable body (4) formed on the transparent film (30). The reason for this is that by placing the nigiri sushi package (1) in this way,
This is because the nigiri sushi (2) can be disassembled and disassembled, and about half of the nigiri sushi (2) can be exposed while being covered with the transparent film (30), so that it can be easily eaten.

The nigiri sushi (2) placed on the packaging table (11) is automatically or semi-automatically packaged by the transparent film (30) according to the procedure shown in FIGS. 4 to 9. That is, first, the short side region of nigiri sushi (2) is wrapped with a transparent film (30), and in this state, the transparent films are fixed to each other by spot welding or the like, and then the ends in the longitudinal direction are squeezed and folded back. The parts are fixed by spot welding or the like. This packaging process may be, for example, all the processes may be automated, or only a part thereof may be automated, and is not particularly limited.
