Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a film for packaging rice balls.

[Conventional technology]

Traditionally, seaweed and rice for rice balls are separated from each other and wrapped in a packaging film, and when eaten, the packaging film is opened by peeling off the cut tape.
There are also various types of onigiri film on the market that are used to wrap rice balls in nori seaweed.

Among them, for example, the one disclosed in Utility Model Application Publication No. 63-156968 proposes a rice ball packaging method in which the packaging film can be easily removed, and the nori is stored inside separated from the rice. The upper side of the package consisting of a front sheet and left and right back sheets is cut out diagonally in a manner that is approximately symmetrical with respect to the cut tape.

[The problem that the idea aims to solve]

However, the above idea has the following problems.

(1) The overall shape of the outer edge seals of the front sheet (exterior film) and back sheet (separation film) is not rectangular, but the upper part in particular is bent at the same angle along the diagonal notch. Therefore, conventional sealing machines cannot be used, and sealing takes time and effort, which increases product costs.

(2) When storing rectangular seaweed, a large space is created above the package, which results in wasted film.

(3) Although the explanation states that the upper seal ends are provided close to the cut tape, in reality they are a little farther apart than the lower seal ends, so the airtightness of the seaweed storage area may be affected. Therefore, the seaweed tends to absorb moisture.

The present invention was developed in view of the above-mentioned problems of the prior art.By simply cutting the outer edge seal portion of the conventional packaging film of this kind into a specific shape, rice and seaweed can be packaged in a separated state. To provide a film for wrapping rice balls which allows the cut tape to be peeled off smoothly and the film to be easily removed.

[Means to solve the problem]

In order to achieve the above object, the rice ball packaging film according to the present invention comprises a rectangular exterior film 1 and a pair of isolating films 2 and 3 arranged so as to overlap approximately at the center of the inner surface thereof, A cut tape 9 is provided at the approximate center of the exterior film 1 along the overlapping edges of the isolation films 2 and 3, and the isolation films 2 and 3 are attached to the outer edges of the exterior film 1.
The outer edge of the rice ball 8 is polymerized, and the cut tape 9 is removed and heat-sealed 4. As a result, rice 8 for rice balls is formed between the outer film 1 and the pair of isolation films 2 and 3.
In a rice ball packaging film that has a bag-like seaweed storage part 6 that can store seaweed 5 without contact with the seaweed, a part of the upper sealed part of the packaging film is diagonally symmetrically cut with respect to the cut tape 9. It is characterized in that the upper end of the notch is notched upward in a straight line substantially parallel to the cut tape 9.

[Effect]

A packaging film is used, which is composed of an exterior film with a cut tape provided in the center and a packaging film that is arranged so as to be overlapped approximately at the center of the inner surface of the exterior film, and the four outer edges of each other are heat-sealed except for the cut tape part. To package rice for rice balls, place the rice for rice balls approximately in the center of the lower inner surface of the packaging film, and fold both lower corners of the packaging film over the rice.

Next, the upper side of the packaging film is bent toward the rice side, and both corners of the upper side are pressed and overlapped onto the rice on the side opposite to the lower corners.

At this time, since there are notches at both corners of the upper side, the portion of the packaging film that overlaps the cut tape is extremely small, and there is no problem in opening the packaging film with the cut tape.

That is, when eating a rice ball packaged as described above, one end of the cutting tape is pinched and pulled, and the outer film is cut at the center.

Next, when one side of the packaging film is pulled sideways, half of the outer film and one of the pair of isolation films are removed, so the remaining outer film and the rice ball made of seaweed and rice remaining on the isolation film side are removed. Half is exposed.

You can eat rice balls in this state,
Of course, the remaining film can also be completely removed before eating.

〔Example〕

Hereinafter, one example of implementing the present invention will be explained based on the drawings.

1 is a rectangular exterior film made of transparent polycellophane or the like; 2 and 3 are a pair of isolating films made of the same material and arranged so as to overlap at the center of the inner surface; A bag-shaped storage section 6 for rectangular seaweed 5 is provided by applying and adhering it to the exterior film 1.

The overlapping ends of the isolation films 2 and 3 are further extended, and the extended portions are folded back to the outside to form folded portions 7 and 7, respectively.

By providing the folded portions 7, 7, the film can be peeled off from the rice ball rice 8 shown in FIG. 4 more smoothly when eating, compared to a film without folded portions.

Next, reference numeral 9 in the figure denotes a cut tape for separating the film, which is provided approximately at the center of the exterior film 1, and is arranged in a straight line along the overlapping edges of the isolation films 2 and 3.

The upper and lower ends of the cut tape 9 are formed into non-sealed portions 4a, 4a having a slight width with respect to the heat-sealed portions 4 on the outer edge of the four peripheries of the film.
This makes it possible to separate the film reliably and easily.

Further, a part of the upper side of the heat-sealing part 4 is notched obliquely and approximately symmetrically with respect to the cut tape 9, and furthermore, the upper end of the notch is cut upward in a straight line substantially parallel to the cut tape 9. It's dark.

In the drawings, reference numeral 10 indicates an oblique cutout portion of the heat sealing portion 4, and reference numeral 11 indicates a straight cutout portion thereof.

Since both the cutout portions 10 and 11 are constructed in this way, in order to make the packaging film F of the present invention, the upper sides of both sides of the rectangular heat-sealed portion 4 are cut into the above-described shape. Just that is fine.

Therefore, when producing the packaging film F of the present invention, it is desirable that the heat-sealed portions 4 on both sides of the film be made wider (approximately twice as wide) as the heat-sealed portions on both the upper and lower ends.

Thus, narrow heat-sealed portions 4b, 4b are formed on both upper sides of the film, while the width of the upper end of the film is slightly narrower than the width L of the lower end.

In FIG. 6, O is the packaging film H of the present invention.
The rice ball is shown by pulling one side of the rice ball in the direction of FIG. 5E and cutting it in half.

[Effect of idea]

Since the present invention is constructed as described above, it can be manufactured easily and at low cost by simply cutting the heat-sealed portion of a conventional rectangular packaging film, and, like conventional packaging films, This method has many advantages such as there is no need to provide any wasteful storage space for the seaweed, and the storage area for the seaweed is highly sealed and can be stored for a long period of time.
