2. Description of the Related Art In recent years, a large number of frozen foods have been put on the market which can be used as they are by simply thawing them in a microwave oven. It has become possible to find products called so-called bowls that are served with food containing seasoning liquid. In general, such a bowl-type frozen food generally has a structure in which frozen rice is put in a container with a lid and a frozen seasoning liquid is placed on it. Was there.

As such a material, for example, a frozen ingredient having at least a first layer of frozen seasoning liquid and a second layer of frozen egg liquid is laminated, and the frozen ingredients are the first layer, the second layer and the first layer. It is included in at least one of the third layers other than the second layer, and is characterized in that when thawed and cooked, the second layer is placed on top of the first layer and cooked by heating. Frozen egg staples and the like have been proposed (JP-A-63-36).
739).

By the way, when the above-mentioned bowl type frozen food is thawed in a microwave oven at home, for example, the seasoning liquid containing ingredients thawed at an early stage is soaked into the rice which is being thawed gradually. When the thawing is completed, the cooked rice completely absorbs the seasoning liquid to give it a soft or simmered texture as a whole, and the ingredients are also dry. Due to lack of water, it began to look like a kogation, and from a qualitative point of view, it would be considerably inferior to the authentic bowls that appear when you order from a store. Most of the foods had a strong image of instant foods, and the taste was not really good.

In order to solve the problems found in such bowl-type frozen foods, various kinds of instant foods in containers have been developed, in which a solid food such as cooked rice and a seasoning liquid containing ingredients are separately stored. For example, a cup-shaped container that stores food ingredients such as rice, noodles, and eel, a bag-shaped container that stores ingredients such as curry soup, noodle soup, and sauce, and an upper lid that holds the bag-shaped container inside. A container for a microwave oven, which comprises a bag-shaped container for accommodating this ingredient with an easily permeable heat-shrinkable resin film, and a resin pin or the like on an upper lid holding the bag-shaped container inside. There has been proposed an instant food container for a microwave oven, which is provided with a semi-broken through hole (Japanese Patent Laid-Open No. 4-376476).

[0006] However, as described above, the instant food container has a bag-shaped container for accommodating ingredients made of a heat-shrinkable resin film having easy penetrability, and has an upper lid holding the bag-shaped container inside. It is characterized by the provision of semi-cut through holes such as resin pins, and the bag-shaped container containing the ingredients is automatically opened by the heating action of the microwave, without any trouble. The aim is to pour ingredients into the foodstuff, and adopts a fairly special configuration as described above, and at the same time, since the through holes are torn at once and opened, the ingredients are made uniform. There was the aspect that it was not always easy to put it on foodstuffs in the state.

As described above, although many frozen foods have been developed so far that can be served immediately by thawing in a microwave oven at home or in a store, for example, cooked rice such as a bowl of rice. In the case of foods that combine different foods with significantly different properties such as and seasoning liquid with ingredients, the finished product after thawing is extremely unsatisfactory, and it appears when ordering at a so-called store. There is a problem in that it is technically extremely difficult to obtain a high quality product that is comparable to such a full-scale bowl, and there is a strong demand for technical improvement in the industry. There was a situation.

[0008]

In view of the above situation, the present inventors have proposed a solid food such as cooked rice with a seasoning liquid and, if necessary, ingredients as a bowl-like product to be served. To solve the above problems found in frozen foods, and develop frozen foods that are of excellent quality and can be finished in the same way as full-scale bowls offered in the store. As a result of earnest research, the use of a specific form of inner lid that can store frozen seasoning liquid and ingredients if necessary, and the use of a specific container that combines these It was found that the intended purpose could be achieved by the above, and the present invention was completed.

The present invention relates to a frozen food in a container, which comprises a solid food such as cooked rice, noodles, pasta, etc., a seasoning liquid stored separately from the solid food, and optionally ingredients in combination, In a new type of container that can be thawed in a microwave oven at home or in the store, put the seasoning liquid and, if necessary, ingredients on top of the solid food evenly just before eating, and immediately serve. It is intended to provide frozen foods.

Further, according to the present invention, after thawing in a microwave oven, the seasoning liquid stored in the inner lid and, if necessary, the ingredients can be easily and uniformly formed on a solid food such as cooked rice by a very simple operation. It is an object of the present invention to provide a frozen food in a container that can be reliably placed.

According to the present invention, if necessary, a sub-solid food such as fried foods, tempura, hamburger steak, meatballs, fried eggs, etc. is placed on a solid food such as cooked rice, and the solid food is optionally cooked. For foods that are seasoned with a seasoning solution in a uniform state and served in the warm state as it is, just by thawing it in a microwave oven, there is no difference from the authentic product that appears when ordering at the store. It is an object of the present invention to provide a frozen food in a container having a high quality and a finished quality.

However, as long as such conditions are satisfied, any However, it is not particularly limited. Specific examples include paper, PP (polypropylene), PE (polyethylene), and PET (polyethylene terephthalate), which can be used alone or in combination.

Next, the method for producing the frozen food in a container of the present invention will be described. First, an appropriate amount of solid foods 2 such as cooked rice, noodles and pasta is put in the container 1 and then frozen in a freezer at about -40 ° C by a conventional method, or separately.
An appropriate amount of these solid foods 2 is stored in the container 1 according to the shape of the container 1 and frozen by a conventional method. In this case, if necessary, the frozen sub-solid food 8 may be separately placed on the solid food 2, or the sub-solid food may be placed and then frozen.

Next, the seasoning liquid and, if necessary, an appropriate amount of the ingredient 5 are put and frozen, and the inner lid 3 is placed so as to cover the opening of the container 1, or the inner lid 3 of the container 1 is placed first. After being placed so as to cover the opening, the seasoning liquid and, if necessary, an appropriate amount of the ingredient 5 frozen according to the shape of the inner lid are stored. Finally, the upper lid 6 is placed by being fitted into the opening of the container 1, and if necessary, the whole is packaged by an appropriate packaging means such as shrink packaging to complete the frozen food in a container of the present invention. In addition, as another manufacturing method, it is possible to appropriately set all of the solid foods 2 before freezing, the sub-solid foods 8, the seasoning liquid and, if necessary, all the ingredients 5 in the container 1 and then freeze at once. In this case, some time is required until the freezing is completed.

[0032]

Next, the operation of thawing and opening the frozen food in a container of the present invention in a microwave oven will be described. The frozen food in the container of the present invention is removed from the shrink wrap if necessary in a microwave oven, the upper lid is removed, put in, and after heating and thawing for a while, frozen solid food 2, seasoning liquid 5, and food. Depending on the situation, the sub-solid food 8 begins to thaw, and the water content of the solid food 2 becomes vapor to start convection in the space formed between the solid food 2 and the bottom of the inner lid 3. Since 8 is heated and the bottom of the inner lid 3 is also heated, the seasoning liquid 5 is also heated as a result.

Further, since this steam gradually escapes from the separating portion 9 provided in the inner lid 3 or the small hole 4 provided as necessary, the inner lid 3 will not come off due to the pressure of the steam. Further, when the upper lid 6 as shown in FIG. 5 is fitted, this vapor also convects with the vapor generated from the seasoning liquid 5 in the space formed between the seasoning liquid 5 and the upper lid 6. After that, the seasoning liquid 5 is heated from above, and these vapors escape from the vapor vent holes 7 of the upper 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 if necessary, and the ends d, d'of the separating portion 9 of the inner lid 3 are removed.
When the gripping portion 11 provided on the inner lid 3 is pulled by grasping it with a finger, the separating portion 9 is separated, and the collar 10 of the inner lid 3 is pulled up, the bottom portion b of the inner lid 3 tilts.
If the seasoning liquid contained therein and, if necessary, the ingredient 5 are naturally dropped onto the solid food 2 and the sub-solid food 8 by its own weight and applied, the target food can be immediately used as it is. Is completed. In this case, if the inclined portion 12 is provided when the bottom portion b of the inner lid 3 is inclined, the seasoning liquid contained therein and, if necessary, the ingredient 5 can be smoothly dropped.

As described above, according to the present invention, by simply thawing in a microwave oven and performing a simple operation, there is no difference from a full-scale rice bowl that appears when ordering at a store. Not only can foods such as foods, noodles, and pasta be easily prepared, but it also has extremely excellent heating and thawing efficiency compared to conventional frozen foods in containers, and the thawing time can be greatly shortened. The effect is obtained.

[0036]

The present invention will be described in more detail based on the following examples, but the invention is not intended to be limited thereto. 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. . Next, separately, an inner lid, that is, a substantially concave side wall having a flange for locking the opening of the container around the bottom and a bottom portion, near the innermost periphery of the flange, of the entire circumference. 150 g of seasoning liquid and ingredients for beef bowl cooked on the inner lid (height 40 mm, material polypropylene) that is provided with a ribbed separation part that is formed on the perforation so that a part of it can be separated as a connection part What was filled and subjected to a freezing treatment for 100 minutes in a freezer at -40 ° C was placed on the opening of the container, and then an upper lid (cardboard) was fitted into the opening of the container to freeze the container. Got food.

Comparative Example As a comparative example, a container was prepared in the same manner as in Example 1 except that the frozen seasoning liquid and ingredients for beef bowl were directly placed on the frozen cooked rice without using the inner lid. Frozen food containing

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 for Example 1, after that, the ribbed separation portion of the inner lid was separated by grasping the ribs with fingers and put into the inner lid. , A comparative evaluation test was carried out for both. As a result, the product of Example 1 was completely thawed, and the seasoning liquid and ingredients were spread almost uniformly over the cooked rice, showing a good finish, and the texture was also very good. There was no difference in appearance from the authentic ones offered in the store.

On the other hand, in the comparative example, the central part of the cooked rice is still unthawed, and the thawed part has a texture like boiling, and the leeks of the ingredients are dried. As a result, kogation was caused due to lack of water, and the appearance was poor and the taste was very poor. As described above, in the case of the frozen food in a container of the present invention, as compared with the product of the comparative example, in particular, the seasoning liquid and the ingredients showed a good finish that was evenly and evenly spread over the cooked rice. , It is positioned as a unique effect not seen in conventional products.

Example 2 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 frozen in a freezer at −40 ° C. for 100 minutes. After the treatment, a frozen Tonkatsu was placed on the cooked rice separately. Next, separately, an inner lid, that is, a substantially concave side wall provided with a flange for engaging with the opening of the container around the bottom and a bottom part, near the innermost periphery of the flange, of the entire circumference. An inner lid (height 40 mm, material polypropylene) provided with a ribbed separation part formed in a chuck structure so that a part thereof can be separated as a connection part is filled with 150 g of the seasoning liquid for a cooked cutlet, -40 A product that had been frozen for 100 minutes in a freezer at 0 ° C was placed on the opening of the container, and then an upper lid (cardboard) was fitted into the opening of the container to obtain a frozen food product in the container. As in the case of Example 1, a product having a high quality and a good finish was obtained.

Example 3 First, 100 g of spaghetti boiled by a conventional method was put 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,
That is, it is composed of a substantially concave side wall and a bottom portion provided with a collar for engaging with the opening of the container on the periphery, and a part of the entire circumference is separated as a connecting portion near the innermost periphery of the collar. Napolitan sauce 1 cooked in an inner lid (height 40 mm, material polypropylene) provided with a ribbed cut-off portion formed in a structure having a cutout portion
What was filled with 50 g and subjected to a freezing treatment 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 to form a container. Frozen food containing The product obtained was of excellent quality, as in Example 1.

[0042]

As described in detail above, according to the present invention,
Since the seasoning liquid is not in direct contact with the solid food or the sub-solid food, when thawed in the microwave, the thawed seasoning liquid does not soak into the solid food or the sub-solid food, and therefore the solid food absorbs the sauce. There is no such thing as a fluffy texture or a cooked texture, a garment of a sub-solid food is not broken, and it is dried and burned due to lack of water.

Further, when thawed in a microwave oven, vapor generated from the solid food is blocked by the inner lid and does not escape directly to the outside of the container, so that the solid food becomes difficult to dry and is heated uniformly. It can be thawed quickly, and since the steam warms the seasoning liquid from the lower side, the thaw time is shortened as a whole.

Further, the inner lid placed so as to cover the opening of the container is formed in the vicinity of the innermost periphery of the flange so that it can be separated leaving a part of the entire periphery as a connecting portion. Since a separate part is provided, after thawing in a microwave oven, separate the separate part and pull it up with the flange of the inner lid, the bottom part of the inner lid will be the seasoning liquid and if necessary the self-weight of the ingredients. Inclining, the seasoning liquid and, if necessary, the ingredients can be easily and reliably placed in a uniform state on the solid food in the form of being naturally dropped by its own weight,
As a result, dishes such as freshly made rice bowls, noodles, and pasta can be easily obtained.
