Description

[Detailed description of the invention] A. Field of industrial application This invention is a packaged triangular rice ball in which the triangular rice ball and seaweed are separated and stored in packaging, and the purchaser can eat the rice ball by wrapping it in seaweed.
Specifically, the present invention relates to an improvement in packaged rice balls that are more hygienically packaged.

B. Conventional technology In recent years, the restaurant industry has developed in line with changes in social life, and rice balls wrapped in seaweed and eaten are sold at supermarkets and grocery stores. Considering its hygroscopicity, the "nori" is stored in a moisture-proof synthetic resin film bag to separate it from the "onigiri". When eating, the bag is peeled off to remove the nori, and the triangular-shaped "onigiri" is placed in the bag. They placed it on nori seaweed, rolled it into a triangular shape, and ate it as rice balls wrapped in seaweed.

With conventional rice ball packaging films like this, it is difficult to open the film bag or wrap the rice ball when eating.
It took a lot of time to transfer the seaweed, and the work of wrapping the seaweed was also troublesome.

Therefore, the present applicant previously provided a cut line in the center of the exterior film in Utility Model Publication No. 63-40152,
We have proposed a rice ball packaging film in which a pair of isolating films are adhered to the inner surface of the film so that their tips overlap, and these three films form a bag-shaped storage area for seaweed.

This packaging film is packaged by placing a triangular rice ball on an isolation film and folding the film 11 into a triangular shape to match the shape of the rice ball, as shown in Figure 1. By peeling off a part of the double film 11 and cutting the film at the cut line 17 in the center, the film can be pulled out in half with the seaweed and rice balls remaining.

Therefore, there was no need to open film bags or transfer rice balls as in the past, and the work of wrapping the seaweed was extremely simple.

C. Problems to be Solved by the Invention However, even the above rice ball packaging film proposed by the present applicant had the following drawbacks.

That is, the packaging film 11 folded into a triangular shape
As the three tops a, b, and c are open as shown in Figure 1, it is easy for germs and small insects to get in, making it unhygienic. The drawback was that the flavor and aroma deteriorated quickly.

D. Means for solving the above-mentioned problems The present invention provides a packaged triangular rice ball that eliminates the above-mentioned drawbacks, in which the rectangular exterior film 1 and its inner surface are arranged so as to be polymerized in a free state approximately at the center thereof. A pair of isolation films 2,
3 to form a storage section 6 for the bag-shaped seaweed 5, and a cut line 7 is provided in the longitudinal direction approximately at the center of the outer film, and the triangular rice balls A are separated from the seaweed 5 on the isolation films 2 and 3. A triangular rice ball is packaged by folding the film along the rice ball A, and is characterized in that the three opening tops a, b and c of the film are sealed with heat seals 9.

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

1 is an exterior film made of transparent polycellophane or the like cut into a rectangle; 2 and 3 are a pair of isolating films arranged so that they overlap in a free state approximately in the center of the inner surface; a seal 4 is applied to the outer edge and the exterior is It is adhered to the film 1 to form a bag-shaped storage section 6 for the seaweed 5.

A cut tape 7a is provided as a cut line 7 in the longitudinal direction of the center of the exterior film 1, and by peeling off the cut tape 7a, the exterior film 1 can be cut in half.

Note that the cut line 7 is a cut tape 7a.
In addition to this, other perforations (not shown) may also be provided.

The isolation films 2 and 3 are preferably made of a material with good releasability, such as a translucent high-density polyethylene film.

In order to package the triangular rice ball A that has been press-formed into a triangular shape using the packaging film constructed as described above, first place the rice ball A on the upper surface of the isolation films 2 and 3 as shown in FIG. After folding the film in half, as shown in FIG. 2, folding seal pieces 8 are further attached to both corners along the outer shape of the triangular rice ball A to fix it.

Next, the three opening tops a of the film,
b and c are completely sealed with a heat seal 9 as shown in FIG.

When eating the triangular rice ball packaged in this way, first peel off the seal piece 8, then pinch and tear off one end of the cutting tape 7a to cut the exterior film 1 at the center.

Next, by pinching both ends of the film and pulling them in opposite directions, only the triangular rice ball A and the seaweed 5 remain, which can be eaten by simply folding both corners of the seaweed 5.

F. Effect of the invention As described above, in the wrapped triangular rice ball according to the present invention, the rice ball A and the seaweed 5 are not only completely isolated within the moisture-proof film, but also formed naturally when folded into a triangular shape. three openings a,
Since b and c are sealed with a heat seal 9, there is no risk of airborne bacteria or small insects entering, making it hygienic and preventing moisture from entering. The dry state of the seaweed 5 can be maintained for a long period of time, and its flavor and aroma do not deteriorate quickly, which is extremely beneficial in practical terms.
