Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a packaging sheet for wrapping individual pieces of sushi.

(Conventional Example and its Problems) In convenience stores and the like, triangular rice balls and nigiri sushi sold for take-out only are individually wrapped in film to prevent the rice from drying out and from getting dusty.

The triangular rice ball packaging sheet is made by sandwiching a sheet of seaweed between two films. In the packaged state, the sheet of nori is separated from the cooked rice by the film, and when the rice ball is eaten, the sheet of nori is directly attached to the cooked rice. A devised method is being implemented to cover the area. However, packaging sheets of the above type have not yet been put into practical use for sushi rolls. This is because even if you try to apply a packaging sheet for triangular onigiri to nigiri sushi, there is a difference in the shape of triangular onigiri and nigiri sushi, and if the ingredients of nigiri sushi are hidden with sheet-shaped nori, the type of nigiri sushi will be different. This is because there was a problem that could not be understood from the outside.

The present invention reveals a packaging sheet for nigiri sushi that can solve the above problems.

(Means for Solving the Problems) The packaging sheet of the present invention sandwiches a sheet-shaped food such as sheet-shaped seaweed between a rectangular transparent outer film 2 and a transparent inner film 3, each of which can wrap a piece of sushi. The inner film 3 is formed by slightly overlapping the longitudinal edges of two rectangular film pieces 31, 31, and the outer film 2 is formed by welding the outer peripheral edges of the inner film 3. The sheet-like food product 4 is formed so as to be separable along the weight portion 30, and the sheet-like food product 4 is placed close to one end of the weight portion 30 of the inner film 3 so that its width center corresponds to the weight portion 30, and the width of the sheet-like food product 4 is The length _w2 corresponds to the length of the nigiri sushi, and the length along the weight part 30 is formed to a length that surrounds three of the four longitudinal sides of the nigiri sushi excluding the surface on which the ingredients 6 are placed. has been done.

(Operations and Effects) A piece of sushi is placed on the inner film 3 of the packaging sheet 1 in the center of the sheet-like food 4, perpendicular to the weight part 30 of the inner film 3, with the ingredients 6 facing upward.

Wrap packaging sheet 1 to wrap the sushi ingredients on all four longitudinal sides including 6, and wrap sheet 1 around both ends of the sushi.
Fold the ends over and attach heat welding or sealing pieces as necessary.

When eating nigiri sushi, divide the outer film 2 into two from the outer edge of the sushi in the longitudinal direction of the sushi, take the folded portions of the packaging sheet 1 at both ends of the sushi, and pull it left and right. Inner film 3 and outer film 2
are pulled together, and the sheet-like food 4 remains on the sushi and covers the cooked rice 5.

As described above, in the packaged state, the sheet-like food 4 is isolated from the cooked rice 5 by the inner film 3 to prevent it from becoming moist, and can be placed directly over the cooked rice 5 when eating sushi.

The packaging sheet 1 is transparent, and the part corresponding to the ingredients 6 is not covered with the sheet food 4, so that the type of sushi can be identified even when it is packaged.

(Example) FIG. 1 is a perspective view showing a state in which the packaging sheet 1 is disassembled.

The packaging sheet 1 consists of a rectangular transparent outer film 2 and a transparent inner film 3, each of which can wrap a piece of sushi, and a sheet food 4, in this example a sheet of seaweed 41, sandwiched between them, and the outer periphery of the film is welded. It is formed by

Outer film 2 has a vertical length L ₁ 140 mm and a width W ₁ 130 mm.
mm, and is a directional film that is easy to tear in the longitudinal direction but difficult to tear in the width direction.

Short parallel cut line 2 in the center of one side edge in the width direction
1 and 21 are applied.

The inner film 3 includes two rectangular film pieces 31,
The weight portion 30 is formed by slightly overlapping the edges in the longitudinal direction of the weight portion 31, and spot heat welding is applied to the weight portion 30 so that it can be peeled off if necessary.

The inner film 3 is stacked on the outer film 2 with the weight portions 30 of the film pieces 31, 31 directed in the longitudinal direction of the outer film 2, and the cut lines 21, 2 of the outer film 2 are stacked on the outer film 2.
The outer periphery except for the vicinity of 1 is thermally welded 10 to the outer film 2.

The sheet-like seaweed 41 accommodated between the inner film 3 and the outer film 2 has a vertical length L ₂ of about 90 mm,
It is formed into a rectangular shape with a width and length _W2 of about 75 mm, which is large enough to wrap three longitudinal sides of a nigiri sushi with a length of about 75 mm. It is enough to cover the sushi ingredients.

The center of the width of the sheet-shaped seaweed corresponds to the weight part 30 of the inner film 3, and it is arranged toward one end of the film on the side away from the parallel score lines 21, 21 of the outer film 2, and if necessary, In order to prevent misalignment, the inner film and the outer film 3 are spot welded 11 surrounding the sheet-like seaweed.

Then, a piece of sushi is placed on the inner film 3 at the center of the sheet-like food 4, perpendicular to the weight part 30 of the inner film 3, with the ingredients 6 facing upward (FIG. 3).

Wrap the packaging sheet 1 so as to wrap the four longitudinal sides including the toppings 6 of the sushi, and wrap the sheet 1 around both ends of the sushi.
Fold the ends of the paper over each other, and heat weld or attach a sealing piece as necessary (Fig. 4).

When eating nigiri sushi, take a photo of the outer film 2 between the cut lines 21 and 21 at the outer edge and pull it in the circumferential direction of the nigiri sushi. The non-directional film 2 is torn along the width between the score lines 21, 21. Take the folded parts of sheet 1 on both ends of the sushi and pull them to the left and right. The inner film 3 and the outer film 2 are pulled together, and the sheet-like seaweed remains on the sushi and covers the cooked rice 5.

As described above, in the packaged state, the sheet-shaped nori is isolated from the cooked rice 5 by the inner film 3 to prevent it from becoming moist, and can be placed directly on the cooked rice 5 when eating.

The packaging sheet 1 is transparent, and the part corresponding to the ingredients 6 is not covered with the sheet-like seaweed 4, so that the type of sushi can be identified even when it is packaged.

In carrying out the present invention, the sheet-like food 4 is not limited to seaweed, but may be made of kelp or soy sauce formed into a film using a special method, etc., with a bulky material between the outer film 2 and the inner film 3 Any type of sheet food 4 can be used as long as it can be accommodated without breaking.

8 and 9 show other embodiments of the outer film 1. In FIG. 8, a cut tape 8 is adhered in the tearing direction of the film, and the cut tape is pulled to divide the film into two.

In FIG. 9, the ends of two rectangular film pieces 20, 20 are overlapped in the same manner as the inner film, and the overlap is welded so that the overlap can be peeled off if necessary.

It goes without saying that the present invention is not limited to the configuration of the above-described embodiments, and that various changes can be made within the scope of the claims for utility model registration.
