DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a method for packaging and preserving seaweed-rolled sushi such as tekka-maki, katsupa-maki, egg-maki, and hipiyo-maki. This invention relates to a method for packaging seaweed-wrapped sushi, which allows the fragrant seaweed-wrapped sushi to be easily eaten by simply cutting it off along the cut line.

B. Conventional technology In recent years, the restaurant industry has developed as social life has changed, and seaweed-wrapped sushi such as tekka-maki, katsupa-maki, egg-maki, and dried piyou-maki have come to be sold at supermarkets and grocery stores. Ta. These seaweed-wrapped sushi sold for eating out are stored in a packaging film bag with the ``seaweed pieces'' separated from the ``formed rice'' considering the hygroscopicity of the seaweed. They opened the package, placed the ``rice'' shaped into a stick, placed it on a piece of ``seaweed,'' rolled it up, and ate it.

C. Problems to be solved by the invention In such a conventional method, it takes time and effort to open the film bag when eating, and it is also necessary to touch the seaweed and cooked rice directly to get them involved, which is unhygienic and troublesome. It required a lot of winding work.

D. Means for Solving the Problems In view of the above drawbacks, the present invention provides isolation films 8, 13 of seaweed pieces 6 so that both edges overlap at the center of the exterior film 3, and also provides isolation films 8, 1
A packaging film bag production process in which a cut line 4 is provided on the outer film 3 along the overlapping portion of No. 3, and the cooked rice 20 formed into a cylindrical shape is rolled in from the inner surface of the starting end, and the inner surface of the terminal end is polymerized with the packaging film bag. This method consists of a wrapping process in which the outer surface is glued, and the wrapping material is cut by pulling the opening piece 22 of the cut line 4, and after the wrapping material is separated, the seaweed pieces 6 are automatically wrapped around the cooked rice 20. It is an object of the present invention to provide a method for packaging seaweed-wrapped sushi that allows the seaweed-wrapped sushi to be eaten hygienically.

E. Example Hereinafter, one example of implementing the packaging method of the present invention will be explained in detail with reference to the drawings.

(1) When line conveyor 1 stops at fixed position a,
A film supply mechanism 2 attached to the side of the line conveyor 1 operates to supply the exterior film 3 to a fixed position on the line conveyor 1.

The line conveyor 1 stops at a fixed position and moves at low speed in the direction of the arrow.

The exterior film 3 supplied onto the line conveyor 1 is made by cutting a transparent synthetic resin film such as polypropylene or polyethylene into a rectangular shape, and as shown in FIG.
An opening tape 4a is provided as an opening tape 4a.

(2) When the line conveyor 1 moves at a low speed again and stops at the next fixed position b, the seaweed piece supply mechanism 5 attached to the side of the line conveyor 1 operates to adsorb the seaweed pieces 6 and place them on the line conveyor 1. is supplied onto the exterior film 3 of. The seaweed pieces 6 supplied onto the exterior film 3 are cut into slightly smaller pieces similar in shape to the exterior film 3.

(3) When the line conveyor 1 moves at a low speed again and stops at the next fixed position c, the isolation film supply mechanism 7 attached to the side of the line conveyor 1 operates to adsorb the isolation film 8, and the outer film 3 Polymerizes to the right side.

The isolation film 8 is made of the same material as the exterior film 3, is shorter than the exterior film 3 by the adhesive margin 9, and is slightly wider than the half cut of the exterior film 3.

(4) When the line conveyor 1 moves forward again and stops at the next fixed position d, the heated pressure bonding roller 10 attached above the line conveyor 1 descends to cover one side and the lower side of the isolation film 8. The film 3 is sealed 11 as shown in FIG.

(5) Next, when the line conveyor 1 moves at a low speed and stops at the next fixed position e, the isolation film supply mechanism 12 attached to the side of the line conveyor 1 operates to adsorb the isolation film 13, and the outer film 3 Polymerizes to the left side of. At this time, the right end of the isolation film 13 overlaps with the left end of the isolation film 8.

The isolation film 13 has the same shape and the same material as the isolation film 8.

(6) When the line conveyor 1 moves at a low speed again and stops at the next fixed position f, the heating pressure bonding roller 14 attached above the line conveyor 1 descends.
The left side of the isolation film 13 and the lower side of the isolation film 8 except for the portion overlapping with the left end of the isolation film 8 are sealed 15 to the exterior film 3.

(7) Next, when the line conveyor 1 moves at a low speed and stops at the next fixed position g, the adhesive application mechanism 16 attached above the line conveyor 1 descends and applies pressure-sensitive adhesive 17 to the adhesive area 9. Apply. This pressure sensitive adhesive 17 does not lose its function as an adhesive even after repeated adhesion and peeling. Note that a release paper 17a is attached to this pressure-sensitive adhesive 17 if necessary.

In the sealing steps 4 and 6 of the above packaging film bag production process, the outer film 3 may be added as needed.
Air vents 18 and 19 are provided in the seals 11 and 15 of the isolation films 8 and 13.

The packaging film bags A manufactured through such a process are stored in a box in a stacked state until the cooked rice 20 is wrapped in them, and then stored and transported in the boxed state. At this time, since each packaging film bag A is polymerized via the pressure sensitive adhesive 17, stability is good.

The cooked rice 20 to be wrapped in a packaging film bag A is formed into a cylindrical shape or the like by a molding machine, with ingredients 21 such as pickles, dried piping, cucumber, salmon, tuna, and tuna.

This cooked rice 20 for hand-rolled sushi is placed on the lower side (inner surface of the starting end of wrapping) of the packaging film bag A, and the outer film 3 is rolled up. At the end of this winding operation, the outer film 3 of the packaging film bag A is rolled up by the pressure-sensitive adhesive 17 applied to the glue margin 9 of the outer film 3 of the packaging film bag A. The glue margin (inner surface of the winding end) of the outer film 3 of the packaging film bag A is adhered, and a cylindrical hand-rolled sushi set is completed.

It should be noted that the present invention is not limited to the above-mentioned embodiments. For example, as shown in FIG. The film 3 may have a structure in which a belt-shaped perforation 4b with an opening piece 22 is bored in the approximate center of the film 3 as a cut line 4.

F. Effects of the invention In this way, pickled incense, dried piyo, cucumber, salmon, tuna,
Seaweed-wrapped sushi in which cooked rice 20 containing toppings 21 such as tuna is wrapped in a packaging film bag A is stored with the seaweed pieces 6 isolated, so that the rice 20 does not get damp and the rice 20 is Isolation film 8,1
3 and is moisturized, so there is no risk of it drying out or deteriorating, and it can maintain its good condition for a long time. And in this state, Tekkamaki,
It is sold as seaweed-wrapped sushi such as katsupa-maki, dried piyou-maki, fried rice-maki, and curry pilaf-maki.

On the other hand, when eating seaweed-wrapped sushi packaged in this manner, the opening piece 22 of the opening tape 4a or band-shaped perforation 4b is pinched and pulled, the outer film 3 is cut at the cut line 4 approximately in the center, and then pulled out. In this way, the isolation films 8 and 13 are pulled out together with the outer film 3, and the cooked rice 20 formed into a stick can be eaten directly with the seaweed pieces 6 wrapped around it.

In addition to the above method, you can also use this method of eating by first removing one of the outer film 3 and isolation film 8, and then removing the remaining films 3 and 13 after eating half of the food, as shown in Figure 7. You can also eat it.

As described above, according to the method of packaging seaweed-wrapped sushi according to the present invention, it is only necessary to separate the outer film 3 at the cut line 4 when eating, and there is no need for the conventional work of peeling off the film or wrapping the seaweed. Therefore, it can be eaten in an extremely hygienic manner since the seaweed and rice are not touched directly with one's hands.
