DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product using alpha rice which can easily provide "rice balls".

[0002]

2. Description of the Related Art Dried alpha rice can be restored to cooked rice by adding hot water (or water) and allowing it to stand for a predetermined time.
The value of use as a simple cooked rice food product for outdoor activities, which has been spreading recently, and as a preserved food product for emergency use in the event of an earthquake or the like has been attracting much attention.

[0003] However, the above-mentioned use of alpha rice for use in large-scale cooking in disasters, which can be considered as a specific use scene, and portable food for outdoor activities such as mountain climbing,
Appropriateness in the specific scene required for the use of portable food when traveling abroad is individually for each use, and the content is not necessarily the same.

[0004] For example, in an emergency such as a disaster, what is basically required is to efficiently recover a large amount of dried alpha rice into cooked rice in a short time. As a portable food product when traveling abroad, the problem of mass processing can be substantially ignored, and rather, it is possible to restore a meal to a state where it can be eaten as easily as possible. Is generally required to have a taste that does not reduce appetite, and these are required depending on the situation.

[0005] By the way, one of the typical uses of dried alpha rice, which is conventionally known as portable food for climbing or traveling, is, for example, Japanese Unexamined Patent Publication No. 1-3.
Japanese Patent Application Publication No. 09648 (Onigiri Reset Using Alpha Rice) discloses an "Onigiri Set" proposed by the present applicant as shown in FIG. 14, which has an inverted triangular shape with a fixed width including alpha rice. Just add hot water to the molded container 101 whose one side of the triangular shape is an open / close lid.
It is a product that can be provided in a shape. It is excellent in that it can maintain a constant quality at room temperature for a long period of time because dried alpha rice is used, and can restore cooked rice by a simple procedure. In FIG. 14, reference numeral 102 denotes a lid of the molding container, 1
Reference numeral 03 denotes a rectangular parallelepiped frame-shaped support base for allowing the molded container 101 to stand in an inverted triangular state.

On the other hand, aside from dried alpha rice, freeze-dried cooked rice products are also provided as simple cooked rice. However, this product is generally hardly popular as a product, probably because it lacks tackiness and easily breaks when taken out of the bag and has insufficient texture.

As described above, some conventional products have already been proposed from the viewpoint of easily providing cooked rice, but freeze-dried cooked rice (so-called freeze-dried cooked rice) has a problem that the texture is insufficient. And it is hardly really widespread.

The product disclosed in Japanese Patent Application Laid-Open No. Hei 1-309648 using dried alpha rice is advantageous in that it can be stored at room temperature for a long period of time. The opposite side is an openable lid that can be opened and closed.Because one vertex of the triangle is the bottom, a separate support is required to make it self-supporting in an inverted triangular state. There was a drawback of stability.

[0009]

SUMMARY OF THE INVENTION The inventor of the present invention has found that the freezing equipment is indispensable even in the distribution process and after purchase by consumers, and the room temperature is lower than that of frozen cooked rice which is not accepted by the general market even in the distribution process or after purchase by the consumer. It is made with the aim of further improving the above-mentioned `` onigiri '' using alpha rice, which can be easily restored to `` onigiri '' rice cooked by putting in boiling water etc. and has excellent texture is there.

That is, the above-mentioned Japanese Patent Laid-Open Publication No.
The simple rice ball product according to No. 8 uses a support base 10 to stand up and use a molded container having one vertex of a triangle at the bottom.
3 was required, which was one drawback. Also, when hot water or water is added to restore rice, some of the alpha rice floats on the water surface without getting wet and does not absorb water, so it does not restore to rice and remains hard. There was also a problem to do. In order to prevent this problem, the molding container 10
A lid can be fitted to the upper opening of 1 and the lid can be provided so as not to generate alpha rice floating on the water surface by bringing the lid into contact with the water surface of the internal hot water. In order to do so, it is necessary to cover the lid with a certain amount of hot water overflowing, and when this is done, it is inevitable that hot water will overflow from the surroundings, and there is a danger of causing burns etc. there were.

[0011] "Onigiri" 1 made with the above mold
15 has a generally triangular shape as shown in FIG. 15, but the portion where the lid fits (that is, the opening of the mold) has no corners and is not round as an “onigiri” and has a poor shape. There was also the disadvantage that the appetite was impaired in a visual sense.

[0012]

SUMMARY OF THE INVENTION In order to achieve the above object, an "rice ball" set using alpha rice according to the present invention has a constant peripheral side wall from the periphery of the triangular bottom surface. A plastic container main body that is formed so as to rise in height and has an open top surface to provide an onigiri-shaped internal space; a lid plate provided so as to close the top surface of the container main body; A predetermined amount of filled alpha rice, and a gas-permeable sheet, preferably a nonwoven sheet, provided in a shape substantially matching the top opening of the container body and placed on the filled alpha rice It is characterized by consisting of a combination.

In the above construction, the container body and the lid plate are preferably made of a plastic material suitable for food packaging materials, such as polypropylene, to which rice and rice are unlikely to adhere, and the sheet is suitable for food packaging materials. Plastic non-woven fabrics such as polyester and polypropylene, Japanese paper, and synthetic non-woven fabrics made of Japanese paper and plastic can be used.

The internal space (cavity) of the container body is usually provided in a size corresponding to the volume of one general rice ball, and this size is obtained by pouring hot water (or water: the same applies hereinafter). An amount of swelling alpha rice is filled into the container body and packaged.

The above configuration is employed in the present invention for the following reasons. The first reason is that, as described above, in the product described in Japanese Patent Application Laid-Open No. 1-309648, the problem that alpha rice that does not wet with water floats on the water surface is as follows.
The present inventor has found that the problem can be solved by placing a suitable air-permeable sheet, which is easily wetted by water and has a large number of pores, which is air-permeable, on the alpha rice. That is, by placing a gas permeable sheet having a large number of pores on alpha rice and pouring hot water from above, the gas (air or nitrogen gas, etc.) present in the container is subjected to the gas flow. It was found that a phenomenon that the material escapes from the pores of the permeable sheet and adheres to the upper surface of the alpha rice by using a water-permeable sheet with good water wettability and acts to suppress the floating alpha rice is obtained. By doing so, it was also found that the conventional problem that the alpha rice floating on the water surface does not swell and remains hard, does not occur.

The second reason for the above is as follows. In other words, it is preferable to sprinkle "rice balls" (plum shiso, tarako, bonito, greens, salmon, etc.) for seasoning after removing the sufficiently swollen and finished "onigiri" from the container. For example, when putting umeboshi in the center of the "rice ball", the conventional Japanese Patent Laid-Open No. 1-309648 is used.
It is difficult to handle the products described in Japanese Patent Publication No. On the other hand, when the flat container body of the present invention having the above configuration is used, since the triangular side surface (the top surface at the time of pouring hot water) is largely open, "sprinkle" is sprinkled. Also, it is easy to put the dried plums in the center of the rice balls, and it is also very easy to put the rice balls once removed from the container back into the container and restore them. is there.

The amount of hot water (or water) poured to restore alpha rice is approximately 1.6 times in the case of pregelatinized glutinous rice and approximately 1.1 times in the case of pregelatinized glutinous rice. It is. In the case of boiling water, water (15 to 15 minutes)
° C), a restoration time of 60 to 70 minutes is usually required. It is preferable to use a breathable sheet having such a property that when the lid rice is removed after the alpha rice has been sufficiently restored to the cooked rice, it does not remain on the restored cooked rice but adheres to the lid. Most of the nonwoven fabric sheets that can be used in the present invention have such properties.

In the above structure, it is preferable that the plastic container having a shape-retaining property is formed by separately forming a container body having a generally "diaper" shape and a lid plate fitted thereto, but not necessarily. However, the present invention is not limited to this. For example, the container body and the cover plate may be formed as an integrated container so that the container body and the lid plate are continuous with one side of the upper end of the side wall of the container body.

According to the above-mentioned invention, "rice balls" which are extremely easy to handle and utilize the excellent simplicity and texture of alpha rice can be safely and successfully produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on embodiments shown in the drawings.

Embodiment 1 This example will be described with reference to FIGS. That is, the “rice ball” set of this example is made of a plastic material having a triangular bottom surface 1a and a circumferential side wall 1b provided so as to rise from the periphery of the bottom surface 1a and having relatively high rigidity and shape retention. The container body 1 (see FIGS. 1, 2 (a), (b)) having an open top surface for providing an internal space 1 d in a shape in which “rice balls” are placed flat by being formed by
A fitting portion 2 is formed around the triangular shape so that it can be fitted to the flange 1c formed at the upper end of the side wall of the container body 1.
a on which the lid plate 2 is formed (FIGS. 1 and 2 (c),
(D), an alpha rice 3 filled in a predetermined amount in the internal space 1d of the container body 1, and a nonwoven fabric sheet 4 placed on the filled alpha rice 3 (FIGS. 1 and 3 (a)). ,
(B)).

The container body 1 and the lid plate 2 are made of, for example, polypropylene having a thickness of about 0.45 mm and the lid plate 2 is made of polypropylene having a thickness of about 0.4 mm. The nonwoven fabric (having a basis weight of 50 g / m ² and a thickness of about 0.11 mm) is used.

The content of the container body 1 is, for example, about 100 ml when the lid is closed, and is appropriate as one rice ball. In this case, usually 4 lg of alpha rice 3 is weighed and filled. The nonwoven sheet 4 is placed thereon, covered with the lid plate 2 and sealed to form a rice ball set package. In addition, a sprinkle (not shown), a rice ball, or the like can be attached to the rice ball set.

As shown in FIG. 10, the container main body 1 of this embodiment has a side wall 1 rising from a flat, triangular bottom surface 1a.
b is preferably tapered so that the upper side from the bottom is slightly wider as a whole obliquely outward, thereby facilitating extraction of the “rice ball” that has been swollen and restored by hot water, and as shown in FIG. In the manufacture of the package 10 for automatically packing alpha rice, empty container bodies can be piled up, and there is an advantage that space is not required.

Further, since the package 10 of this embodiment has a flat shape as shown in FIG. 12, it is suitable for stacking package products, and can be easily stored during transportation or carrying. In addition, there is an advantage that the storage volume may be small.

Embodiment 2 In this embodiment, as shown in FIG.
The lid plate 22 is continuous with one side of the side wall rising from the triangular bottom surface so as to be bent. The amount of alpha rice to be filled in the container body 21 and the placement of the breathable sheet can be performed in the same manner as in the embodiment 1.

According to the container 20 of this embodiment, as in the case of the mobile phone 1, alpha rice can be easily swollen and restored with hot water to make "rice balls", and the swollen rice balls can be easily extracted. . Further, according to this example, since the lid plate 22 is connected to the container body 21, there is an advantage that the lid plate 22 is not lost when the lid plate 22 is removed.

[0028]

Example 1 Using the container body 1, lid plate 2 and nonwoven fabric sheet 4 of Embodiment 1 described above, 41g of alpha rice 3 was weighed and filled, and an "onigiri" set which was tightly sealed was manufactured.

Next, the lid plate 2 of the package is removed,
66 ml of hot water 5 at 95 ° C. is poured from above the nonwoven fabric sheet 4 (see FIG. 4), and then the cover plate 2 is covered and about 20 ml.
Let stand for minutes. As a result, the alpha rice swelled sufficiently with time and became full to the point where the pressure in the container was applied (see FIGS. 1 and 5). In addition, when the hot water is poured, the filler layer of alpha rice is maintained in the nonwoven fabric sheet 4 with its surface flatness, so that the amount of hot water to be poured can be made just the right amount, and the lid plate 2 is covered. Sometimes the boiling water did not overflow. In order to control the amount of hot water to be added, it is also preferable to write a mark (for example, a line) on the inner surface of the side wall of the container body 1 as a guide of the amount of hot water.

Next, when the cover plate 2 was removed, the nonwoven fabric sheet 4 could be removed with the back surface of the cover plate 2 stuck.

When the container body 1 is placed on a dish, dried seaweed or a clean plastic film with the opening thereof facing downward to take out the swollen rice balls, the "onigiri" in the container easily comes off. The rice balls 6 without corners shown in 6 were obtained. For example, it was possible to sprinkle the “sprinkle” attached to it and eat it.

Comparative Example 1 For comparison, as shown in FIGS. 7 and 8, hot water 5 was poured into a container body without placing the nonwoven fabric sheet 4 of Example 1 on alpha rice 3. , Alpha rice that did not get wet appeared on the surface of the water when boiling water was poured. In addition, there was a recess in the part of the alpha rice where hot water was poured, making it difficult to control the amount of hot water poured.

For this reason, when the lid plate 2 is put on, there is a large amount of hot water overflowing and there is a risk of burns.

Example 2 One umeboshi 71 of about 20 g was pressed into the center of alpha rice before hot water was poured, and the nonwoven sheet 4 was placed thereon. As a result, rice balls 7 containing dried plums shown in FIG. 9 were easily obtained.

Example 3 An onigiri set was prepared in which the alpha rice (white rice) of Example 1 was filled with 50 g of realpha rice (red rice) containing 6 g of pregelatinized red beans.

Remove the lid plate 2 of the rice ball set and pour hot water in the same manner as in Example 1 (pour amount 55 m
l) I made red rice "Onigiri". This is sesame salt
It was easy to sprinkle and eat.

Example 4 35 g of alpha rice (white rice) with frozen and dried flavors (oil fried, shiitake, carrot, burdock, konjac, vegetable oil,
An onigiri set filled with a mixture of 6 g of sugar, seasonings, sorbitol, vitamin E, etc.) was produced.

When the lid plate 2 of the rice ball set was removed and hot water was poured and swelled and restored in the same manner as in Example 1, the fifth rice ball was easily obtained and could be eaten.

[0039]

As described above, according to the rice ball set using alpha rice of the present invention, a flat container body having a triangular top surface as an opening, and a lid plate closing this opening, are used. When swelling and restoring, you can easily make a rice ball that can be pulled out, and simply place a breathable sheet on the filled alpha rice, the alpha rice that does not get wet, which was a difficult problem, floats on the water surface when water is poured This provides an excellent effect that it is possible to prevent the risk of burns due to overflow of the poured hot water when the lid is closed at the time of swelling.

In addition, a support stand is not required as compared with a conventional rice ball set in which a container is set upright in an inverted triangle.
It is easy to place horizontally anywhere for restoration, and even if hot water is poured, water injection is widely used and cheap.

Furthermore, two pieces before and after the restoration of water injection,
It is also possible to pile up with three pieces, without taking space for storage etc.
In addition, there is an effect that the packaging form before water injection is extremely compact and portable.
