Description

[Detailed explanation of the idea] This invention relates to a packaging material for nigiri rice or stick-shaped sushi.

More specifically, this packaging material itself is a bag, and the seaweed is stored inside the bag, so that even after a long period of time, the seaweed absorbs the moisture from the rice and maintains its tension without becoming damp. The seaweed is maintained in a certain state, and the seaweed does not move out of the bag even after unwrapping, and it is possible to easily roll rice balls or sushi sticks by opening the top of the bag and exposing the seaweed. This invention relates to a packaging material for nigiri rice or stick-shaped sushi.

It is desirable that such packaging materials meet the following three requirements.

(1) The work of inserting seaweed into a bag can be easily performed.

(2) The moisture from the rice must be completely blocked so that the seaweed does not become damp.

(3) It is easy to open the bag after unwrapping and wrap it in seaweed.

However, these three requirements, for example, if you try to completely block the moisture from the rice in (2), the bag will have to be tight, and as a result, (1) and (3). It is difficult to satisfy all the requirements at the same time, so the packaging materials that have been proposed so far all have advantages and disadvantages, and may not be fully satisfactory. It wasn't.

The purpose of this invention is to provide a simple packaging material that satisfies these three requirements relatively well.

That is, this invention divides a rectangular strip-shaped plastic film into two sides and a center surface in the longitudinal direction with two bent parts as boundaries, and divides these into two sides with the two sides facing upward and the center surface. Fold the plastic film at the bent part so that the surface faces down so that both ends of the plastic film overlap at the center of the center surface, and extend close to and parallel to one long side of the plastic film. Gently apply a thin seal along the entire length of the center surface to join the two upper sides and the lower center surface, and then apply another seal across the plastic film at the overlapping area at both ends. The two surfaces on both sides are joined together by thinly and lightly applied, and one of the two bent portions is cut along the bent portion, and the upper two surfaces on both sides are joined. A packaging material for nigiri rice or stick-shaped sushi that is made by inserting seaweed into the bag-shaped part between the lower center surface and cutting one of the two bent parts mentioned above. By making the opening of the bag-like part large to facilitate the work of inserting seaweed into the bag-like part, the overlapping parts of the plastic film are also sealed across the plastic film at the overlapped parts at both ends, thereby making it possible to prevent the rice from leaving the rice. Preventing moisture from entering the bag-like part through the gap in the polymerized part and dampening the seaweed,
Furthermore, the two seals mentioned above can be easily peeled off to make it easier to open the bag after unwrapping and wrap it in seaweed.

Next, this invention will be explained in detail with reference to the drawings.

1 to 4 show an example of the manufacturing process of the packaging material of this invention, and FIG. 4 shows the finished state as well as the process of inserting seaweed into it.

First, the rectangular band-shaped transparent plastic film 1 shown in FIG.
, B and the center surface C, and then fold them into the folded part 6, so that the surfaces A and B on both sides are on top and the center surface C is on the bottom.
Fold at 7, both sides edges 2 of plastic film 1
, 3 overlap each other by a width a at the center of the film 1 (center of surface C) (FIG. 2).

The width a may be about 1°5 to 2.5 cm.

Then, as shown in FIG. 3, a seal 8 is lightly applied near and parallel to one of the long sides 4 (or 5) of the plastic film 1, joining surfaces A, B, and C along this line.

Further, a seal 9 is applied lightly across the plastic film 1 near the center of the width a to the overlapping portions of the both end portions 2 and 3, and the surfaces A and B are joined along this line.

It is desirable that the bonding force of these seals be such that when the two surfaces are pulled, the film can be separated without tearing.

Finally, the bent portion 6 (or 7) is cut with a cutter 15 such as a knife to separate the surface A (or surface B) and the surface C.

The length to be cut with the knife 15 may be from the long side 5 of the plastic film 1 to just before the seal 8.

The cut point may be either the bent portion 6 or the bent portion 7, but as will be described later, in consideration of convenience when using this packaging material, the cut point may be cut at the overlapping portion of the both end portions 2 and 3. It is preferable that the surface (surface A in the figure) be a folded part (the folded part 6 in the figure).

Furthermore, as a method of cutting, the vicinity of the bent portion 6 may be cut off from above the packaging material 12 along its entire length. It is preferable to determine the lengths of the sides A, B, and C, and therefore also the positions of the folds 6 and 7 on the plastic film 1.

In this way, the packaging material 12 of this invention is completed, in which the bag-shaped portion 10 is formed between the three surfaces A, B, and C, as shown in FIG.

Then, insert the seaweed 11 into this bag-shaped part 1 from the opening on the long side 5 side.
0, it will be in the state shown in FIG. 5, and from this state nigiri rice or stick-shaped sushi will be packaged.

The bag-like part 10 of the packaging material 12 has two continuous openings, one on the long side 5 and the other on the side cut by the knife 15, so that the opening can be made wide and the seaweed 11 can be easily inserted.

In addition, when the seaweed 11 is inserted as deeply as possible, the plastic film 1 is adjusted so that the two gaps b' between the long side 4 or 5 of the plastic film 1 and the side of the seaweed 11 have approximately equal lengths. By determining the width of the seal 8, the position of the seal 8, the width of the seaweed 11, etc., when wrapping nigiri rice or stick-shaped sushi, the entire package can be symmetrical and aesthetically pleasing.
Favorable in terms of texture.

In the above description, plastics such as polypropylene, polyethylene, and vinyl chloride resin can be used as the material for the plastic film 1, but polypropylene is preferable.

Next, a case in which the packaging material of this invention formed in this way and with seaweed inserted therein is applied to packaging rice balls will be explained with reference to the drawings.

FIG. 6 shows a state in which nigiri rice 13 is placed approximately in the center of the packaging material 12 in which seaweed 11 is inserted in order to wrap it.

To wrap the nigiri rice 13 from this state, first fold the side B (the side that includes the folded part that was not cut by the knife 15) to wrap half of the nigiri rice 13, and then fold the side A. Wrap the remaining half of Nigiri Meshi 13.

At this time, the four corners of the packaging material 12 are also fully inserted, and the entire nigiri rice 13 is wrapped around it to complete the packaging (FIG. 7).

In this way, the bent portion 7 that was not cut by the knife 15
The side of surface B that includes is folded in first to wrap the rice ball 13, and the side of surface A that includes the part where the folded part 6 is cut with the knife 15 and the cut part becomes one of the openings of the bag-shaped part 10. The side is then folded in and the back side of the side B side that was folded first (the back side of the half side of side B side of side C) Nigiri rice 13 from the top.
Therefore, even after a long period of time, the moisture of the rice ball 13 will not enter the bag-like part 10 through one of the openings of the bag-like part 10 created by cutting the bent part 6 with the knife 15. Therefore, the seaweed 11 hardly ever gets wet due to this passage.

In addition, since the seals 9 are applied to the overlapping portions of both ends 2 and 3 of the plastic film 1, the moisture of the rice ball 13 will not leak through the gap between the overlapping portions and reach the bag-shaped portion 10, and the seaweed 11 is completely protected from the moisture of rice balls 13 through this passage as well.

In the end, the seaweed 11 only comes into contact with moisture in the atmosphere through the two openings of the bag-like part 10, but the nigiri rice 13 can be eaten within one to two days after packaging.
During this period, the seaweed 11 is almost completely maintained in its original state and does not lose its puffy, taut state and flavor.

Note that after the packaging is completed, the packaging is sealed with a sealing tape 16 or the like to prevent it from unraveling.

Next, the procedure for unwrapping the nigiri rice 13 and wrapping it in seaweed in order to make it edible will be explained.

Of course, in order to unwrap the package, it is sufficient to follow the above-mentioned packaging procedure in reverse, and once the unpacking is completed, the state returns to the state shown in FIG. 6.

From this state, first, as shown in Figure 8, lay down the nigiri rice 13 onto side B (the side on which the sticker 8 will be removed last), and the side end 2 on side A side is indicated by the arrow in the figure. Pull it upward to peel off the seals 9 and 8, and then unfold side A to expose half of the seaweed 11.

Then, as shown in FIG. 9, transfer the nigiri rice 13 onto one of the exposed surfaces of the seaweed 11, and pull the side edge 3 on the surface B side upward as shown by the arrow in the figure to remove the last remaining surface B. Side C
After peeling off the seal 8, the surface B is unfolded to expose the remaining half of the seaweed 11.

In this way, as shown in FIG. 10, the packaging material 12 is completely unfolded, and the nori 11 is completely exposed, as if the nori 11 and nigiri rice 13 were placed on the surface C of the plastic film 1 shown in FIG. This makes it possible to easily wrap the seaweed 11 on top of this film.

Then, the user can enjoy the nigiri rice 13 wrapped in seaweed 11 that retains its rich flavor.

When the nigiri rice 13 is wrapped in the packaging material 12 by the method described above, and when the wrapping is unwrapped and the seaweed 11 is wrapped, the folded part cut by the knife 15 is cut by the folded part 6. It may be any of the new song sections 7.

However, as shown in FIG. 8, packaging is started from the state in which the nigiri rice 13 is placed horizontally on the packaging material 12, and the packaging is unwrapped and returned to the state before the start of packaging. When using packaging material 12, nigiri rice 1
3 is of course the side where the bent part is not cut by the knife 15 (
In the case of the figure, it will be placed on the surface B of the bent part 7 side), but in that case, when exposing the seaweed 11, it will be unfolded based on the other surface A, so both ends 2,
In the overlapping part of No. 3, it is preferable that the side end 2 on the side of surface A is located in the upper layer. It is desirable that the new bent part (in the case of the figure, the folded part 6) where the (plane A in the figure) is folded is cut.

Note that without unfolding side B, wrap the nori 11 around half of the nigiri rice 13 from the state shown in FIG.
Pull out from side B onto the exposed part of side C, and place nigiri rice 1 here.
You can also wrap the other half of 3 with seaweed 11 to finish it off.

(In FIGS. 9 and 10, traces of the seals 8 and 9 are omitted for clarity of illustration.

) In the above work process, the work of peeling off the seals 8 and 9 can be easily done by lightly pulling upward the side edge 2 on the side A and the side edge 3 on the side B.

When applying the packaging material of this invention to the packaging of stick-shaped sushi, as shown in FIG. 8 will be peeled off last)
The only difference is that the package is placed on top and rolled up toward the other end, and the other steps and handling methods are the same as those used for wrapping nigiri rice. The details are often omitted as they are sufficiently clear to those skilled in the art.

As mentioned above, when the sushi bar 14 is placed on the surface B of the end of the packaging material 12 at the beginning of packaging the sushi bar 14, the sushi bar 14 is unwrapped (unwrapped, the sushi bar 14 is unwrapped again as shown in FIG. 11). Return to the state before starting), then immediately pull the side edge 2 of the upper layer upward to peel off the seals 9, 8, and unfold the side A.
It is convenient because the work process up to winding can be simplified.

Therefore, when starting packaging, the folded part 7 that will be rolled up first is not cut, and the other folded parts 6 (FIG. 3) are cut with the knife 15, so that the moisture in the stick-shaped sushi 14 is eliminated. It is preferable to completely block out the seaweed 11.

In other words, the cutting by the knife 15 is performed in such a way that the upper surface of the plastic film 1 (the surface from which the seal 8 is peeled off first) is folded at the portion where the opposite ends 2 and 3 of the plastic film 1 overlap. It is preferable to apply it on the side.

In this way, the packaging material of this invention has two openings in the bag-shaped part that accommodates the seaweed (the seal 8 that joins surfaces A, B, and C).
Since there is a continuous opening across two places (the side opposite to the side where the seaweed was cut and the side where the bent part was cut by the knife 15), when inserting the seaweed into the bag-shaped part, the opening is opened. The large opening makes it very easy to insert seaweed.

In addition, when wrapping nigiri rice or stick-shaped sushi, if the side with the folded part cut with a knife is folded in last to complete the packaging, the moisture of the rice will be released from the opening created by the cutting into the bag-shaped part. It will no longer invade the seaweed and make the seaweed moist.

Furthermore, since the overlapping parts at both ends of the plastic film are also sealed across the film, moisture from the rice will not enter the bag-shaped part through the gaps between the overlapping parts and dampen the seaweed. , the nori is almost completely protected from the moisture of the rice.

The seal and the seal placed near and parallel to one long side of the plastic film can both be removed with light force, making it easy to unfold both sides of the bag after unpacking. It also makes it easier to open it and wrap it in seaweed.

Thus, when the packaging material of this invention is used to package nigiri rice or stick-shaped sushi, it is possible to easily make nori-wrapped nigiri-meshi or nori-wrapped sushi using seaweed that does not lose its flavor, and it is as if the rolled nigiri-meshi or maki is made without packaging. You can enjoy the flavor of fresh seaweed and the crunchy texture of the seaweed, just like sushi.

Also, if the dimensions are determined so that when the seaweed is inserted all at once into a bag-shaped part, the front and back sides of the seaweed in the insertion direction are equidistant from each side of the plastic film, the whole can be packaged symmetrically, which improves the aesthetics and taste. It doesn't spoil the feeling.

In this way, this invention is an extremely simple and practical packaging material.
