BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frozen food in a container in which a solid food such as cooked rice, a seasoning liquid stored separately from the solid food, and optionally ingredients are stored in combination, For details, at home or at a store, simply thaw it in a microwave oven and perform a very simple operation to store the seasoning liquid stored separately and, if necessary, the solid ingredients such as cooked rice, without any special effort. The present invention relates to a frozen food product in a container which can be placed on a food product in a uniform state in a simple and reliable manner and can be immediately used for food in such a condition.

[0002]

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.

First, in the present invention, as the target food, specifically, for example, beef bowl, parent and child bowl, Chinese rice bowl, Tianjin bowl, marbo bowl, katsu bowl, tempura bowl, curry rice, katsu curry, hamburger curry, hayashi rice. Typical foods include curry udon, fox udon, ramen, spaghetti (Napolitan sauce, meat sauce, etc.), kalbi kuppa, chazuke, etc. However, the present invention is not limited to these foods, and any foods similar to these can be used as appropriate.

As is clear from the above-exemplified foods, the solid foods in the present invention are food materials that are the bases of the various foods described above, and particularly those that use carbohydrates as the main raw material. Typical examples include cooked rice, noodles, pasta, etc.,
In addition, any food may be used as long as it is also mainly composed of carbohydrates and is not easily affected by freezing and thawing, and is not particularly limited.

On the other hand, the sub-solid food in the present invention corresponds to so-called ingredients which are additionally placed on the above-mentioned solid food as required, and more specifically, fried foods, tempura, hamburgers and meatballs. , Ingredients such as fried eggs,
Alternatively, noodle utensils such as baked pork and fried food are listed as representative ones, but the present invention is not limited to these, and any suitable one can be used as long as it is similar to these.

The seasoning liquid in the present invention is a seasoning liquid for seasoning the solid food as described above, and immediately before serving it on the solid food, if necessary, together with ingredients, By applying in a hot state, it is used for the purpose of finally seasoning the solid food, for example, curry soup, noodle soup, sauce, sauces, etc., the seasoning liquid, according to the intended food Any appropriate one can be used, and they may be prepared by a conventional method.

Next, the frozen food in a container of the present invention will be specifically described with reference to the drawings.

1 and 2 show an inner lid of a frozen food product in a container of the present invention, and FIG. 3 shows an entire frozen food product in a container. In FIG. 3 showing the whole frozen food product in a container of the present invention, reference numeral 1 denotes a container, and a solid food product 2 such as cooked rice is put in a frozen state at the bottom thereof. In this case, for example, in the case of a bowl such as a cutlet bowl, it is also possible to place the sub-solid food 8 such as pork cutlet in a frozen state on the solid food 2 such as cooked rice.

On top of them, an inner lid 3 consisting of a substantially concave side wall and a bottom portion, which is provided around the periphery thereof with a collar 10 for engaging with the opening of the container, and the bottom portion of the inner lid 3 is provided with a seasoning liquid and a necessary liquid. In the frozen state of the ingredient 5, the container 5 is placed so as to cover the opening of the container 1, and a cylindrical flexible film having the bottom of the inner lid opened downward is wound in a certain direction. In addition to being formed into a state, the inner lid 3 is provided with at least one or more small holes 4 at a portion where the seasoning liquid (and ingredient) 5 after thawing does not come into contact with the inner lid 3 if necessary.

Next, FIGS. 1 and 2 show the inner lid 3 placed on the opening of the container as described above. That is, FIG.
FIG. 2 is a perspective view showing a case in which the bottom portion b of the inner lid 3 is formed in a state in which the tubular flexible film 9 having the lower portion opened is wound upward, and FIG. 2 shows the lower portion of the inner lid 3 opened. The perspective views showing a state in which the tubular flexible film 9 is extended downward and the lower opening d is opened are shown.

Of the substantially concave side wall e and bottom b of the inner lid 3, a tubular flexible film 9 having an open bottom, for example, a PP film, is formed so as to be freely wound from the bottom b to the lower opening d. It is necessary to provide a winding portion a formed by Further, the inner lid 3 is provided around the periphery with a collar 10 for engaging with the opening of the container 1, and a small hole 4 can be provided if necessary. In the inner lid 3,
The flange 10 may be of any width as long as it can be locked in the opening of the container 1, and its shape is the same as the case of the substantially concave side wall e and bottom b of the inner lid 3. The structure is not particularly limited.

The winding portion a is preferably formed by, for example, forming a tubular flexible film 9 having an open lower portion in a state of being rolled up, but is not limited thereto. The film may have any structure as long as it is rolled in a certain direction, such as a film formed in a rolled-up state so that it is narrowed down in the lateral direction, or a combination of the upward direction and the lateral direction. It is possible to employ an appropriate means and it is not particularly limited. In addition, the length of the winding portion a is also such that the seasoning liquid located at the bottom portion b of the inner lid 3 and, if necessary, the ingredient 5 naturally falls onto the upper portion of the container 1 by its own weight when the winding portion a is extended downward. To the extent that the side wall e and the bottom portion b of the inner lid 3 can securely hold the seasoning liquid and the ingredient 5 if necessary at that position when formed in a rolled-up state. Any material may be used, and there is no particular limitation. Further, if necessary, an upper lid 6 having a vapor vent hole 7 on the upper surface thereof is fitted on the inner lid 3 so as to be openable and closable in the opening of the container 1.

In consideration of the above-mentioned structure, the container in the present invention is preferably cup-shaped, dombly-shaped or tray-shaped having a certain height and an appropriate area. Further, as the material of the container 1, the inner lid 3, and the upper lid 6 used as necessary, since they are frozen at the time of manufacturing or heated by a microwave oven at the time of thawing,
It is necessary that the container 1 and the inner lid 3 have at least freezing resistance and heat resistance, and that the container 1 and the inner lid 3 have further water resistance, and that the winding portion a of the inner lid 3 has flexibility. Although it is required, any material may be used as long as such conditions are satisfied, and 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, a method for producing a frozen food in a container according to 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 can be separately placed on the solid food 2, or the sub-solid food 8 can be placed and then frozen.

Next, the seasoning liquid and, if necessary, an appropriate amount of the ingredients 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, a seasoning liquid and, if necessary, an appropriate amount of the ingredient 5 frozen according to the shape of the inner lid 3 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.

[0031]

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, and after heating and thawing for a while, frozen solid food 2, seasoning liquid (and ingredients) ) 5, and depending on the food, a supplementary solid food 8
Begins to thaw, and the moisture contained in the solid food 2 becomes steam to start convection in the space formed between the solid food 2 and the bottom of the inner lid 3, and this steam heats the solid food 2 itself and the sub-solid food 8, and Since the bottom of the inner lid 3 is heated, the seasoning liquid (and the ingredient) 5 is also heated as a result.

Further, since this vapor gradually escapes from the small holes 4 provided in the inner lid 3, if necessary, the inner lid 3 will not come off due to the pressure of the vapor. Further, when the upper lid 6 as shown in FIG. 3 is fitted, the vapor also contains the seasoning liquid (and the ingredients) 5 even in the space formed between the seasoning liquid (and the ingredients) 5 and the upper lid 6. Convection is caused together with the steam generated from the above, and then the seasoning liquid (and the ingredient) 5 is heated from the upper part, and these steam escapes from the steam vent hole 7 of the upper lid 6.

When the thawing by the microwave oven is completed, first, the container 1 is taken out of the microwave oven, the upper lid 6 is removed if necessary, and then the collar 10 of the inner lid 3 is pulled up to pull up the tube in which the winding portion a is wound. Flexible film 9
Of the seasoning liquid (and the ingredients) 5 are fully extended, and the bottom portion b of the inner lid 3 communicates with the lower opening d. If the food is naturally dropped onto the solid food 2 and the sub-solid food 8 and applied, the intended food that can be immediately used for food is completed.

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 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.

[0035]

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, an inner lid, that is, a substantially flexible side wall provided with a collar for locking the opening of the container around the inner lid, and a bottom portion. Inner lid (height 40 mm, material polypropylene) formed by winding a different film upward
Then, the cooked beef bowl seasoning liquid and 150 g of ingredients were charged, and the product was frozen for 100 minutes in a freezer at -40 ° C, and placed on the opening of the container, and then the upper lid ( Cardboard) was fitted into the opening of the container to obtain a frozen food in a container.

Comparative Example As a comparative example, a container was prepared in the same manner as in Example 1 except that the seasoning liquid and ingredients for frozen beef bowl were directly placed on 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 is heated in a microwave oven of 500 W for 3 minutes, and then, for Example 1, the flange of the inner lid is gripped and lifted to extend the rolled film downward and put the seasoning liquid in the inner lid. After that, a comparative evaluation test was performed 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 portion of the cooked rice is still unthawed, and the thawed portion 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. Then, separately, an inner lid, that is, a substantially flexible side wall provided with a flange for engaging with the opening of the container around the bottom and a bottom portion, and the bottom portion of the inner lid is opened in a cylindrical flexible shape. Inner lid (height 40 mm, material polypropylene) formed by winding the film upward
Then, add 150 g of seasoning liquid for cooked katsu-don to
After placing a product that has been frozen for 100 minutes in a freezer at −40 ° C. on the opening of the container, an upper lid (cardboard) is fitted into the opening of the container to obtain a frozen food product in the container. It was
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-shaped 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, a cylindrical flexible film, which is composed of a substantially concave side wall and a bottom portion provided with a collar for locking the opening portion of the container around the periphery, and the bottom portion of the inner lid is opened downward, is formed in the upward and lateral directions. Inner lid (height 40
mm, material polypropylene), filled with 150 g of cooked Napolitan sauce, and stored in a freezer at -40 ° C for 10
The product that had been frozen for 0 minutes was placed in the opening of the container, and then the upper lid (cardboard) was fitted into the opening of the container to obtain a frozen food product in the container. The product obtained was of excellent quality, as in Example 1.

[0041]

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, the 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 a state in which the bottom of the inner lid is rolled up in a certain direction with a cylindrical flexible film whose lower part is opened. So, after thawing in a microwave oven, pull up with the collar of the inner lid, the wrapping part at the bottom of the inner lid extends downward due to the seasoning liquid and, if necessary, the weight of the ingredients. , In the form that it naturally falls due to its own weight,
It can be simply and surely placed on a solid food in a uniform state, and as a result, dishes such as freshly cooked rice bowls, noodles and pasta can be easily obtained.
