DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frozen food in a container. More particularly, the present invention relates to a frozen food in a container that can be eaten only by thawing it in a microwave oven.

[0002]

2. Description of the Related Art In recent years, many frozen foods that can be eaten simply by being thawed in a microwave oven have been circulating. Something like that has come to be seen. These frozen foods such as bowls generally have a structure in which frozen cooked rice is placed in a container with a lid, and the frozen seasoning liquid containing the ingredients is placed thereon. However, when the above frozen food is thawed in a microwave oven,
The seasoned liquid containing the thawed ingredients gradually penetrates into the rice that is being thawed, and when the thawing is completed, the rice rice will have a texture that looks like a soaked or boiled rice. In addition, the ingredients were burnt due to lack of water, and the bowls that came out when ordering at the cafeteria seemed to be so.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a food which is cooked on rice or the like and, if necessary, fried or the like, is seasoned with or without ingredients, and is eaten in a warm state. The purpose is to provide frozen food in a container that can be eaten freshly made, such as immediately after being ordered when ordering at a cafeteria.

[0004]

According to the present invention, there is provided the above-mentioned object by providing a partition between a frozen rice cooked in the bottom of a container and a frozen seasoning liquid containing ingredients placed on the cooked rice in a concave shape. This is based on the finding that can be almost solved.

That is, according to the present invention, a frozen main solid food is placed at the bottom of a container, and if necessary, a frozen sub-solid food is placed on the main solid food. A concave inner lid provided with at least one or more small holes covers the opening of the container with a frozen seasoning liquid containing or not containing an ingredient placed on the bottom of the upper surface of the inner lid. A frozen food in a container, wherein an upper lid provided with a vapor vent hole on an upper surface is fitted into an opening of the container.

Hereinafter, the frozen food in a container according to the present invention will be described in detail. First, as foods targeted by the present invention, specifically, beef bowl, oyakodon, chukadon, Tianjin rice, mabodon, katsudon, tendon, curry rice, cutlet curry, hamburger curry, Hayashi rice, curry udon, fox Foods such as udon, ramen, and spaghetti (napolitan sauce, meat sauce) that are eaten with a hot seasoning liquid are included.

As is apparent from the above-listed foods, the main solid food in the present invention is mainly made of carbohydrates, and specifically includes cooked rice, boiled noodles, pasta and the like. Similarly, it is not particularly limited as long as it is mainly made of carbohydrate and is not easily affected by freezing and thawing. On the other hand, the auxiliary solid food in the present invention is to be placed on the main solid food,
Specific examples include noodle tools such as fried, tempura, hamburger, meatball, fried egg, or baked pork, oil fried and the like.

[0008] The seasoning liquid containing or not containing the ingredient in the present invention (hereinafter simply referred to as seasoning liquid) is a cooked seasoning liquid, which is added to the main solid food and, if necessary, to the auxiliary solid food. Means a food that is formed by applying the food in a hot state, and may be prepared by a conventional method according to the intended food.

Next, the configuration of the frozen food in a container according to the present invention will be described with reference to the drawings. (1) is a container,
At its bottom, a main solid food (2) such as cooked rice is put in a frozen state. In the case of a cutlet bowl or the like, an auxiliary solid food (8) such as tonkatsu is further placed on the main solid food (2) in a frozen state.

On top of this, a concave inner lid (3) is placed on the container (1).
The seasoning liquid (5) is placed in a frozen state on the bottom of the upper surface of the inner lid (3). Further, the inner lid (3) is provided with at least one or more small holes (4) around the upper part of the side surface where the seasoning liquid (5) after thawing does not contact.

Further, on the inner lid (3), an upper lid (6) provided with a vapor vent hole (7) on the upper surface is fitted to the opening of the container (1).

In consideration of the above configuration, the shape of the container in the present invention is preferably a cup-shaped or tray-shaped one having a certain height and an appropriate area. Further, since the material of the container, the inner lid and the upper lid is frozen or heated by a microwave oven, it is necessary that the material has freezing resistance and heat resistance. It is necessary to have the property, but there is no particular limitation as long as the above condition is satisfied. In particular,
Paper, PP (polypropylene), PE (polyethylene),
PET (polyethylene terephthalate) and the like.

Next, a method for producing a frozen food in a container according to the present invention will be described with reference to the drawings. First, an appropriate amount of a main solid food such as cooked rice is put in the container (1) and then frozen in a freezer or the like, or an appropriate amount separately frozen in a container shape is put in the container (1). If necessary, separately freeze the auxiliary solid food (8) to the main solid food (2)
Put on top. Next, an appropriate amount of the seasoning liquid is put and the inner lid (3) frozen is placed so as to cover the opening of the container (1), or the inner lid (3) is first opened to open the container (1). After placing it so as to cover the part, put a suitable amount separately and freeze it according to the shape of the inner lid. Finally, the upper lid (6) is fitted to the opening of the container (1) to complete the process. As another manufacturing method, it is conceivable to set all the main solid food, sub-solid food and seasoning liquid before freezing in a container and then freeze at once, but since it takes time until the freezing is completed, Not preferred.

Next, the opening operation of the frozen food in a container according to the present invention after thawing by a microwave oven will be described with reference to the drawings. Shortly after heating the microwave after putting the frozen food in the container into the microwave, the frozen main solid food (2), the seasoning liquid (5) and, depending on the food, the auxiliary solid food (8) starts to thaw, and the main solid food From (2), the moisture contained therein becomes steam and starts convection in the space formed between the inner lid (3) and the bottom, and this steam is used as the main solid food (2).
Since the bottom of the inner lid (3) as well as itself and the auxiliary solid food (8) are heated, the seasoning liquid (5) is also heated as a result. Further, since the vapor gradually escapes from the small hole (4) provided in the inner lid (3), the inner lid (3) does not come off due to the pressure of the vapor. Further, this steam also causes convection together with the steam generated from the seasoning liquid (5) in the space formed between the seasoning liquid (5) and the top lid (6), and this time, the seasoning liquid (5) Will be heated from above. Finally, these vapors escape through the vapor vent (7) of the top lid (6).

When the thawing by the microwave oven is completed, first, the container is taken out of the microwave oven, the upper lid (6) is removed, and then both ends of the inner lid (3) are lifted to remove the seasoning liquid (5) contained therein. If it is clear above the main solid food (2) and the auxiliary solid food (8), the intended food is completed.

As described above, in the present invention, foods such as katsudon, which are ready for ordering at a cafeteria or the like by simply thawing in a microwave oven, can be easily prepared, as well as conventional containers. The thawing time can be greatly reduced as compared with frozen foods.

[0017]

EXAMPLES Hereinafter, the frozen food in a container according to the present invention will be specifically described based on examples. Example 1 First, 100 g of cooked rice was put in a cup-shaped container (100 mm in diameter × 100 mm in height, material / paper) so as to be flat, and subjected to a freezing treatment in a freezer at −40 ° C. for 100 minutes. did. Next, a seasoning liquid 15 for beef bowl cooked separately on the inner lid (height: 40 mm, material: polypropylene)
After filling with 0 g and performing a freezing treatment in a freezer at −40 ° C. for 100 minutes, the container was placed in the opening of the container, and then an upper lid (cardboard) was fitted into the opening of the container. .

Comparative Example The same procedure as in Example 1 was carried out except that the frozen seasoning liquid for beef bowl was directly placed on frozen rice without using the inner lid.

The frozen foods in containers of Example 1 and Comparative Example were
Each was heated in a microwave oven of 500 W for 3 minutes, and in Example 1, after the seasoning liquid in the inner lid was put on the cooked rice, the two were compared. As a result, the thing of Example 1 was completely thawed, and was in a state of freshness, but in the case of the comparative example, the central part of the cooked rice was not yet thawed, while The textured portion was as if it had been boiled, and the leeks and other ingredients on the ingredients were burnt, which was very likely.

Example 2 First, 100 g of cooked rice was put in a cup-shaped container (diameter 100 mm × height 100 mm, material / paper) so as to be flattened in a freezer at −40 ° C. for 100 minutes. After the freezing treatment, the separately frozen tonkatsu was placed on cooked rice. Next, a seasoning liquid 15 for katsudon cooked separately on a middle lid (height: 40 mm, material: polypropylene)
After filling with 0 g and performing a freezing treatment in a freezer at −40 ° C. for 100 minutes, the container was placed in the opening of the container, and an upper lid (cardboard) was fitted to the opening of the container.

Example 3 First, 100 g of spaghetti boiled by a conventional method was placed in a tray-like container (length 150 × width 100 mm × height 100 mm,
(Material / paper) and flattened in a freezer at -40 ° C for 100 minutes. Next, 150 g of the cooked Napolitan sauce was separately charged into the inner lid (height: 40 mm, material: polypropylene) and subjected to a freezing treatment in a freezer at −40 ° C. for 100 minutes. After placing, the upper lid (cardboard) was fitted to the opening of the container.

[0022]

According to the present invention, the seasoning liquid is not in direct contact with the main solid food or the auxiliary solid food, so that when thawed in a microwave oven, the thawed seasoning liquid is used as the main solid food or the auxiliary solid food. It does not seep into the solid food, so that the solid food does not absorb the sauce and has a texture that is soggy or boiled, the clothes of the auxiliary solid food do not collapse, and the ingredients do not have enough water to burn out . In addition, since the steam from the solid food does not escape directly to the outside of the container due to the inner lid, the solid food becomes difficult to dry and is uniformly heated, so that it can be quickly thawed. The thawing time is shortened as a whole by heating from below.
