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

[0002]

2. Description of the Related Art In recent years, many frozen foods that can be eaten simply by thawing in a microwave oven have come into the market. Something like that has come to be seen. Frozen foods such as these bowls generally have a structure in which frozen cooked rice is put in a container with a lid, and a frozen seasoning liquid containing ingredients is placed thereon. However, when the frozen foods as described above are thawed in a microwave oven,
The thawed seasoning liquid gradually soaks into the rice that is being thawed, and when the thawing is complete, the cooked rice will have a smoky texture or a simmered texture. In addition, the ingredients were kogated due to lack of water, and when I looked at the bowls that appeared when I ordered at the cafeteria, it was very likely.

DISCLOSURE OF THE INVENTION The present invention relates to a food in which a fried food or the like is placed on cooked rice, etc., if necessary, and a seasoning liquid with or without ingredients is eaten in a warm state. The purpose is to provide frozen food in a container that can be eaten in a freshly prepared state, such as immediately after it came out when ordered at the dining room.

[0004]

According to the present invention, the above-mentioned problems are solved by putting a partition between the frozen cooked rice placed in the bottom of the container and the frozen seasoning liquid containing ingredients to be placed on the container with a concave wrap. It was made based on the finding that can be solved.

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

The frozen food in a container according to the present invention will be described in detail below. First, as the food subject to the present invention, specifically, beef bowl, oyakodon, Chinese rice bowl, Tianjin rice, marbo bowl, katsudon, tempura bowl, curry rice, katsu curry, hamburger curry, hayashi rice, curry udon, fox. Examples include udon, ramen, spaghetti (Napolitan sauce, meat sauce) and other foods that can be eaten with a hot seasoning liquid.

As is clear from the above-mentioned foods, the main solid food in the present invention is mainly composed of carbohydrates, and specifically includes cooked rice, boiled noodles, pasta and the like. Similarly, it is mainly composed of carbohydrates and is not particularly limited as long as it is not easily affected by freezing and thawing. On the other hand, the secondary solid food in the present invention is to be placed on the main solid food,
Specific examples thereof include fried foods, tempura, hamburgers, meatballs, fried eggs, or noodle utensils such as baked pork and fried chicken.

The seasoning liquid with or without the ingredients in the present invention (hereinafter, simply referred to as seasoning liquid) is a seasoning liquid which has been cooked, and which is added on top of the main solid food and, if necessary, sub-solid food. It means that the above-mentioned food is formed by applying it in a hot state on the above, and it may be prepared by a conventional method according to the intended food.

Next, the structure of the frozen food in a container according to the present invention will be described with reference to the drawings. (1) is a container,
A main solid food (2) such as cooked rice is put in a frozen state at the bottom thereof. In the case of a cutlet bowl or the like, a sub-solid food (8) such as pork cutlet is placed on the main solid food (2) in a frozen state.

On top of that, a concave inner lid (3) is attached to the container (1).
Is placed so as to cover the opening of the above, and 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 side surface where the seasoning liquid (5) after thawing does not come into contact.

Further, on the inner lid (3), an upper lid (6) having a vapor vent hole (7) on its upper surface is fixedly attached to the opening of the container (1).

In consideration of the above-mentioned constitution, the shape of the container in the present invention is preferably a cup shape or a tray shape having a certain height and an appropriate area. Further, the material of the container, the inner lid and the upper lid, which are frozen or heated by a microwave oven, need to have freeze resistance and heat resistance. However, if the above conditions are satisfied, there is no particular limitation. In particular,
Paper, PP (polypropylene), PE (polyethylene),
Examples thereof include PET (polyethylene terephthalate).

Next, a method for producing a frozen food product in a container according to the present invention will be described with reference to the drawings. First, an appropriate amount of 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 is separately frozen according to the shape of the container and put in the container (1). Separately frozen sub-solid food (8) as main solid food (2) if necessary
Place it on top. Next, an appropriate amount of seasoning liquid is put in the frozen inner lid (3) so as to cover the opening of the container (1), or the inner lid (3) is first opened in the container (1). After placing it so that it covers the part, put an appropriate amount separately into the shape of the inner lid and freeze. Finally, the top lid (6) is fitted into the opening of the container (1) to complete. As another manufacturing method, it is possible to freeze all of the main solid food before freezing, the sub-solid food and the seasoning liquid in the container and then freeze at once, but it takes time to complete the freezing. Not preferable.

Next, the opening operation of the frozen food in a container according to the present invention after being thawed by a microwave oven will be described with reference to the drawings. After putting the frozen food in a container into a microwave oven and starting heating for a while, the frozen main solid food (2), the seasoning liquid (5), and depending on the food, the sub-solid food (8) begins to thaw and the main solid food. From (2), the water content becomes vapor and starts convection in the space created between the bottom of the inner lid (3) and this vapor becomes the main solid food (2).
Since the bottom of the inner lid (3) as well as itself and the sub-solid food (8) is heated, the seasoning liquid (5) is consequently heated. Further, since this vapor gradually escapes from the small hole (4) provided in the inner lid (3), the inner lid (3) will not come off due to the pressure of the vapor. Furthermore, this vapor also causes convection in the space formed between the seasoning liquid (5) and the upper lid (6) together with the vapor generated from the seasoning liquid (5), and this time the seasoning liquid (5). Will be heated from the top. Finally, these vapors escape through the vapor vent holes (7) in the top lid (6).

When the thawing by the microwave oven is completed, first, the container is taken out from 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 on the main solid food (2) and the auxiliary solid food (8), the intended food is completed.

As described above, according to the present invention, not only can food such as katsu-don and the like that is in the state when it is ordered and placed in a cafeteria is simply prepared by simply thawing it in a microwave oven, but it is not possible to put it in a conventional container. The thawing time can be significantly shortened compared to frozen foods.

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 cooked by a conventional method was placed in a cup-shaped container (diameter 100 mm × height 100 mm, material / paper) so as to be flat, and then frozen in a freezer at −40 ° C. for 100 minutes. did. Next, the seasoning liquid 15 for beef bowl separately cooked on the inner lid (height 40 mm, material polypropylene)
The container was filled with 0 g and subjected to a freezing treatment in a freezer at −40 ° C. for 100 minutes, placed in the opening of the container, and then an upper lid (cardboard) was fitted to the opening of the container. .

Comparative Example A sample was prepared in the same manner as in Example 1 except that the frozen seasoning liquid for beef bowl was placed directly on the frozen cooked rice without using the inner lid.

The frozen foods in the 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 for the inner lid was sprinkled on the cooked rice, both were compared. As a result, the product of Example 1 was completely thawed and had a fresh appearance, whereas the product of Comparative Example had the central portion of the cooked rice still unthawed, while The part that had been cooked had a simmered texture, and moreover, there was kogation in the leeks, etc. of the ingredients, which was almost the case.

Example 2 First, 100 g of cooked rice cooked by a conventional method was placed flat in a cup-shaped container (diameter 100 mm × height 100 mm, material / paper) and kept in a freezer at −40 ° C. for 100 minutes. After freezing, the pork cutlet that had been separately frozen was placed on the cooked rice. Next, the seasoning liquid 15 for a katsu-don, which was separately cooked on the inner lid (height 40 mm, material polypropylene)
What was filled with 0 g and frozen in a freezer at -40 ° C for 100 minutes was placed in the opening of the container, and then an upper lid (cardboard) was fitted into the opening of the container.

Example 3 First, 100 g of spaghetti boiled by a conventional method was placed in a tray-like container (vertical 150 × width 100 mm × height 100 mm,
Material / paper) was placed flat so that it was frozen in a freezer at -40 ° C for 100 minutes. Next, separately fill an inner lid (height 40 mm, material polypropylene) with 150 g of cooked Napolitan sauce, and freeze-process in a freezer at -40 ° C for 100 minutes. After placing, the top lid (cardboard) was fitted into the opening of the container.

EFFECTS OF THE INVENTION According to the present invention, since the seasoning liquid is not in direct contact with the main solid food or the sub-solid food, when thawed in the microwave oven, the thawed seasoning liquid is the main solid food or the sub-solid food. Therefore, the solid food does not absorb the sauce and has a soft texture or a stewed texture, the batter of the secondary solid food does not collapse, and the ingredients do not burn due to lack of water. . Further, since the steam coming out of 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 can be uniformly thawed so that the solid food can be quickly thawed, and further the above steam makes the seasoning liquid. As it is warmed from below, thawing time is shortened as a whole.
