Description

[Detailed description of the invention] (Field of industrial application) The present invention is a packaging device that can be used for food production, and can be used to heat and eat processed rice products such as rice balls as they are in a microwave oven, or to heat them in a microwave oven. The present invention relates to a packaging tool for manufacturing foods such as cooked rice, which can also be used to manufacture grilled rice balls.

(Prior Art) Conventionally, various packaging devices for cooked rice processed foods such as rice balls have been commercially available, such as bag-shaped ones and sheet-shaped ones.

Such packaging devices generally consist of an inner wrapping material for wrapping cooked rice and an outer wrapping material for wrapping the inner wrapping material together with the cooked rice through seaweed.When eating, the inner wrapping material can be pulled out. Rice and seaweed are combined and eaten together.

(Problem that the invention aims to solve) However, in the first place, such packaging tools are
This product is intended for so-called snack foods, and is intended to be eaten after opening the package after purchase. is not suitable.

In other words, since molded rice originally contains a large amount of water, when heated in a microwave oven, the water in the rice evaporates, and this adheres to the inner packaging material, causing stickiness when eaten. The point was hot.

In particular, when making grilled rice balls in a microwave oven or heating pre-made grilled rice balls, seasonings such as soy sauce applied to the grilled rice balls may become sticky and the original texture of the grilled rice balls may be significantly impaired. I've come across a problem.

In addition, since the above-mentioned packaging devices are used with edible material such as seaweed interposed between the inner and outer packaging materials, the seaweed may become moist due to the evaporation of water as described above. There was a problem with getting it to work.

An even more important point is that the packaging device with the structure described above is used to eat processed rice food by pulling the inner packaging material out from the outer packaging material, but when heated in a microwave oven, the inner packaging material evaporates due to moisture evaporation. and the outer packaging material may inadvertently adhere to each other, and as a result,
A unique problem has also arisen in that the inner wrapping material cannot be pulled out smoothly from the outer wrapping material.

This invention was created to solve all of these problems. Even if processed rice food is heated in a microwave oven while packaged, it will not become sticky as described above when eaten. In addition, it is possible to prevent the seaweed from becoming moist as much as possible, and there is no problem in pulling out the inner packaging material, making it suitable for heating in a microwave oven, as well as for manufacturing and heating baked rice balls, etc. It is an object of the present invention to provide a packaging tool that can be used for both the production and processing of cooked rice processed foods.

(Means for solving the problem) The present invention was made in order to solve the above problem, and the means for solving the problem is an inner packaging material for packaging foods such as cooked rice, In a packaging device for manufacturing foods such as cooked rice, which is composed of an outer packaging material for packaging the inner packaging material together with the food through an edible material such as seaweed 16, at least an inner surface of the inner packaging material has water absorbency. It consists in becoming composed.

(Function) In other words, since at least the inner surface of the inner packaging material is water-absorbing, even if the packaged cooked rice food is heated in a microwave oven, the water that evaporates from the cooked rice will be absorbed by the inner surface of the inner packaging material. It is quickly absorbed by the skin and therefore does not become sticky after opening the package.

In addition, as a result of moisture being absorbed by the inner surface of the inner wrapping material, penetration of moisture into the seaweed interposed between the inner wrapping material and the outer wrapping material is prevented as much as possible.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows an outer bag of a packaging device for producing rice balls as an example, where A is a front view and B is A-A of A.
A line cross-sectional view is shown.

In Figure 1, reference numeral 1 denotes a transparent outer bag made of a film made of polyethylene terephthalate, which has heat-resistant gas barrier properties, and is shaped like an inverted isosceles triangle from the front with an open top as shown in the figure. . Reference numeral 2 denotes a folding piece that is bendable to close the upper opening 3, and is formed by extending one piece 4 of the outer bag 1 from the other piece 5.

Reference numeral 6 denotes a tear-off piece for opening the tip of the outer bag 1, and is integrally provided at the tip of the outer bag 1 through a perforation 7 cut in the transverse direction.

FIG. 2 shows a perspective view of the inner bag.

That is, the inner bag 8 is made of a film made of a water-absorbing polymer, has slightly smaller external dimensions than the outer bag 1, and is formed in substantially the same shape as the outer bag 1. 9 is one piece 10 of the inner bag 8 and the other piece 1
The bent piece 9 is formed to extend from the bent piece 9.
, there is a cross-shaped cut 1 that allows a large number of the inner bags 8 to be hung from the hanging rods 12, 12 at the same time and to be torn off.
3 are formed on both sides.

When using the rice ball manufacturing packaging device consisting of the outer bag 1 and the inner bag 8 as described above, first blow air into the inner bag 8 and open the top opening 14 as shown in FIG. 3A. The rice ball 15, which has been previously coated with soy sauce or the like and dried, is stored in the inner bag 8. Next, the inner bag 8 is torn off from the hanging rods 12, 12, the folded piece 9 is bent, and the rice ball 15 is placed inside. The bag 8 is sealed, and then seaweed 16 is wrapped around the outer circumferential surface of the inner bag 8 as shown in FIG. After inserting the bag 8 so that the tip 17 of the bag 8 reaches the tip of the outer bag 1,
By folding the folded piece 2 and pasting the label 18, the rice ball is packaged as shown in C and D of the figure.

Next, when heating the rice balls, the packaging device used for manufacturing and packaging the rice balls as described above is placed in a microwave oven and heated.

In this case, since the inner bag 8 is made of the above-mentioned water-absorbing polymer film, even if the water evaporates from the rice ball 15 by heating in the microwave oven, the water is absorbed by the inner bag 8. It will be absorbed quickly. Therefore, the inner bag 8 prevents moisture from penetrating into the seaweed 16 side.

When eating rice balls 15, first,
After removing the label 18 of the folded piece 2 of the outer bag 1, tear off the tear piece 6 formed at the tip of the outer bag 1 through the perforation 7 as shown in FIG.
7, the tear-off piece 6 is torn off and its tip is opened as shown in Figure B, and at the same time, the inner bag 8 is also pulled out, and the seaweed 16 is inside the outer bag 1 as shown in Figure C. Since only the rice ball 15 wrapped around the outer circumferential surface remains, the rice ball with seaweed can be easily taken out from the top opening 14 of the outer bag 1 and eaten.

In this case, the inner bag 8 is made of a water-absorbing polymer film as described above, and the moisture evaporated by heating is absorbed into the inner bag 8 in advance, so that the hands do not become sticky when eating as described above.

Furthermore, since the inner bag 8 itself does not become sticky due to its high absorbency as described above, it does not inadvertently adhere to the outer bag 1, and therefore does not interfere with the operation of pulling out the inner bag 8 as described above. There is no possibility that this will occur.

Furthermore, since the outer bag 1 has gas barrier properties,
The moisture absorbed into the inner bag 8 is retained in the inner bag 8 as it is.

In the above embodiment, the perforation 7 is formed so that the tip of the outer bag 1 can be torn off, so that the tip of the outer bag 1 is formed into a bottomed shape. Although a favorable effect was obtained in that the nori seaweed 16 could be prevented from getting wet, the tip of the outer bag 1 does not need to be formed in a bottomed shape, and may be formed with an opening in advance. good.

Further, the outer packaging material is not limited to a bag-like material such as the outer bag 1 of the above embodiment, but may be a sheet-like material as shown in FIG. 5, for example.

That is, the outer film 19 as an example of the outer packaging material shown in FIG.
0, and both ends 21, 21 of the seaweed 16 are inserted into the pockets 20, 20.

Similarly, the inner packaging material is not limited to a bag-like material like the inner bag 8 of the above embodiment, but may be a sheet-like material.

Alternatively, as shown in FIG. 6, for example, a sheet-like inner film 22 and an outer film 19 may be welded at their peripheral edges, and the inner film 22 may be folded back. . As in this embodiment, the outer packaging material and the inner packaging material may be sealed and integrally formed. In addition, in FIG. 6, 24 indicates a cut tape.

In any case, the form of the outer packaging material and the inner packaging material does not matter.

Furthermore, although a film made of water-absorbing polymer is used as the material of the inner packaging material in the above embodiment,
The material is not limited to a water-absorbing polymer film, but any water-absorbing material that can absorb moisture that evaporates from cooked rice may be used.

The water-absorbing polymer may be of any type, such as starch, cellulose, or synthetic polymer.

Moreover, it does not matter whether or not it has gas barrier properties.

Further, in the above embodiment, the entire inner packaging material is made of a water-absorbing material, but the entire inner packaging material does not necessarily have to be made of a water-absorbing material.
It may be formed into a layer, and only the inner layer may be made of a water-absorbing material. Furthermore, particles made of a water-absorbing material may be attached to the inner surface of an inner packaging material made of a general synthetic resin film. In any case, the means for imparting water absorbency to the inner packaging material is not critical, as long as at least the inner surface of the inner packaging material is configured to have water absorption properties.

Furthermore, since polyethylene terephthalate, which has excellent heat resistance, was used as the material for the outer packaging material in the above example, a favorable effect was obtained in that it could sufficiently withstand heating in a microwave oven. It is not limited to the examples.

Furthermore, although this example describes the case where rice balls are simply heated and eaten, it is also possible to produce grilled rice balls, for example, by extending the heating time or increasing the heating temperature. .

In particular, when producing grilled rice balls, soy sauce or the like is applied to the rice balls in advance, so that the above-mentioned effect of preventing stickiness due to water absorption by the inner bag 11 becomes even more effective.

In addition, in the case of grilled rice balls, we are not limited to manufacturing.
It is also possible to use the above manufacturing and packaging tool when heating pre-manufactured grilled rice balls.

Further, the type of cooked rice processed food is not limited to rice balls as in the embodiment, but can also be applied to steamed sushi, etc., and the type thereof is not limited. Furthermore, although the subject of the present invention is primarily processed cooked rice food, it is also possible to apply the present invention to foods other than processed cooked rice food.

Furthermore, the type of edible material interposed between the outer packaging material and the inner packaging material is not limited to the seaweed 16 as in the embodiment. Moreover, it is not limited to a sheet-like one.

(Effects of the invention) As mentioned above, the present invention is constructed so that at least the inner surface of the inner packaging material has water absorbency.
Even if food such as cooked rice is heated in a microwave oven while packaged, the water that evaporates from the food is quickly absorbed by the inner packaging material, so there is no stickiness when eating.

In particular, when producing grilled rice balls or the like, the rice balls are coated with soy sauce or the like in advance, which has the practical benefit of making the above-mentioned sticky prevention effect due to moisture absorption even more effective.

Furthermore, as a result of the moisture being absorbed by the inner packaging material as described above, the inner packaging material and the outer packaging material do not accidentally stick together, and therefore, for example, when both packaging materials are bag-shaped, This has the effect that it does not become difficult to pull out the inner wrapping material from the outer wrapping material.

Further, as a result of moisture being absorbed by the inner wrapping material, there is an advantage that penetration of moisture into the edible material such as seaweed interposed between the inner wrapping material and the outer wrapping material is prevented as much as possible.
