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 the 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 with ingredients gradually soaks into the rice that is being thawed, and when the thaw is completed, the rice will absorb the sauce and become soft or simmered. Also, the ingredients were burnt due to lack of water, and when I looked at the bowls that appeared when I ordered at the cafeteria, it was definitely the case.

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.

Furthermore, the present invention is a container-frozen container that is ready to be eaten in a freshly prepared state, such as immediately after it comes out when ordering at a cafeteria, by a simple opening operation after thawing in a microwave oven. The purpose is to provide food.

[0005]

According to the present invention, a partition is put between a frozen cooked rice placed in the bottom of a container and a frozen seasoning liquid containing ingredients to be placed on the container with a concave wrap,
This is done based on the finding that the above problems can be almost solved.

That is, 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. An inner lid having a rounded W-shape and a central portion protruding slightly above the height of the container is placed so as to close the middle of the container, and the upper surface of the inner lid is placed. Frozen seasoning liquid with or without ingredients is placed in the bottom part, and an upper lid with a steam vent hole in the center of the top surface allows the middle part of the inner lid to slightly protrude from the steam vent hole. The present invention provides a frozen food product in a container, which is fitted in the opening of the container in this state.

The frozen food in a container according to the present invention will be described in detail below. As the food subject to the present invention,
Specifically, beef bowl, oyakodon, Chinese rice bowl, Tianjin rice, marbo bowl, katsudon, tempura bowl, curry rice, cutlet curry, hamburger curry, hayashi rice, curry udon, kitsune udon, ramen, spaghetti (Napolitan sauce, meat sauce), etc. , Foods that can be eaten with 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 and pasta. There is no particular limitation as long as it is mainly composed of carbohydrates and is not easily affected by freezing and thawing. On the other hand, the supplementary solid food in the present invention is to be placed on the main solid food, and specifically includes fried food, tempura, hamburg, meatballs, fried eggs, or baked noodles such as baked pork and fried food. .

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. What is said to form the said foodstuff by applying in a hot state on the above, may be adjusted by a conventional method according to the intended foodstuff.

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 product (7) such as pork cutlet is placed on the main solid food product (2) in a frozen state.

An inner lid (3) is placed thereon so as to close the middle of the container (1), and the seasoning liquid (4) is frozen in a ring shape at the bottom of the upper surface of the inner lid (3). It is put in the opened state. Further, the central portion of the inner lid (3) is in a state of slightly protruding from a vapor vent hole (6) provided on the upper surface of the upper lid (5) fixedly attached to the opening of the container (1).

The shape of the container in the present invention is preferably a cup shape having a certain height and an appropriate area in consideration of the above-mentioned constitution. In addition, the material of the container, the inner lid and the upper lid must be freeze-resistant and heat resistant because they are frozen or heated by a microwave oven. However, the inner lid needs to be flexible so that it can be pulled out from the vapor vent hole of the upper lid, but is not particularly limited as long as the above conditions are satisfied. Specific examples include paper, PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate), and the like.

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). Next, if necessary, the separately frozen sub-solid food (7) is placed on the main solid food (2). Then, an inner lid (3) made of a flexible packaging material such as a wrap formed as shown in the figure is placed thereon so as to close the middle of the container (1), and an appropriate amount of seasoning liquid is separately added to the bottom of the inner lid. Put frozen thing in a ring shape according to the diameter, or pour an appropriate amount of seasoning liquid into the bottom of the inner lid (3) fitted in the mold and then close the middle of the frozen thing in the container (1) Put on. Finally, after slightly projecting the central portion of the inner lid (3) into the vapor vent hole (6) of the upper lid (5),
The upper lid (5) is fitted into the opening of the container (1) to complete the process.
As another manufacturing method, it is conceivable that all the solid food, fried food and seasoning liquid before freezing are set in a container and then frozen at once, but this is not preferable because it takes time to complete the freezing.

Next, the thawing action of the frozen food in a container according to the present invention by a microwave oven and the opening operation after thawing will be described with reference to the drawings. A short time after putting the frozen food in a container into a microwave oven and starting heating, the frozen main solid food (2), the seasoning liquid (4) and, depending on the food, the sub-solid food (7) 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 causes the main solid food (2) itself and the sub-solid food (7). ), Of course, heats the bottom of the inner lid (3), and consequently also the seasoning liquid (4). Further, since this vapor gradually escapes from the gap between the inner lid (3) and the side wall of the container, the inner lid (3) does not come off due to the pressure of the vapor. Further, this vapor also causes convection in the space formed between the seasoning liquid (4) and the upper lid (5) together with the vapor generated from the seasoning liquid (4), and this time the seasoning liquid (4). Will be heated from the top. Finally, these vapors escape through the vapor vent holes (6) in the top lid (5).

After thawing by the microwave oven, the container is taken out from the microwave oven, the central portion of the inner lid (3) protruding from the vapor vent hole (6) of the upper lid (5) is pulled out, and then the upper lid (5). ) Is removed, the desired food is completed.

As described above, according to the present invention, not only can food such as a cutlet and rice in the state when ordered at a cafeteria or the like is simply prepared by simply thawing in a microwave oven, but also the conventional container. The thawing time can be greatly shortened as compared with the frozen food containing. In addition, despite the inner lid, the time and effort of opening are almost the same as the conventional one.

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, an appropriately shaped inner lid (height of the central portion is 60 mm, depth of the bottom portion is 4 mm) on the cooked rice.
0 g, polypropylene film), and 150 g of seasoning liquid for beef bowl, which was separately cooked, was frozen in a freezer at -40 ° C for 100 minutes and frozen in a ring shape with an outer diameter of 90 mm and an inner diameter of 30 mm. Was put into the bottom through the central portion of the inner lid, the central portion of the inner lid was further projected from the vapor vent hole of the upper lid (cardboard), and then the upper lid was fitted into 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 inner lid was pulled out from the steam vent hole of the upper lid and the seasoning liquid was applied 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, an appropriately shaped inner lid on top of the above cooked rice (height of central portion 60 mm, depth of bottom portion 40 m)
m, material / polypropylene film) and separately heated and cooked 150 g of seasoning liquid for beef bowl in a freezer at -40 ° C for 100 minutes to obtain an outer diameter of 90 mm and an inner diameter of 3
What was frozen in a ring shape of 0 mm was put into the bottom through the central portion of the inner lid, and the central portion of the inner lid was projected from the vapor vent hole of the upper lid (cardboard), and then the upper lid was placed in the container. Was fitted into the opening of the.

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 suck the sauce to give a soft texture or a cooked 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. Furthermore, despite the presence of the inner lid, the labor required for opening is almost the same as the conventional one.
