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 containing a combination of a solid food such as cooked rice, a seasoning liquid separately stored therewith, and ingredients as required. In detail, at home or in stores, thaw with a microwave oven and apply a very simple operation, and the seasoning liquid stored separately and solid ingredients such as cooked rice etc. as necessary without special labor are required. The present invention relates to a frozen food in a container that can be easily and reliably placed on a food in a uniform state, and can be immediately provided for food in such a state.

[0002]

2. Description of the Related Art In recent years, a large number of frozen foods that can be served directly to a food simply by thawing in a microwave oven have come to market, and include, for example, solid foods such as cooked rice. Products called so-called rice bowls, which are served with food in a state in which a seasoning liquid containing ingredients is applied, have come to be seen. In general, such bowl-type frozen foods generally have a structure in which frozen cooked rice is put in a container with a lid, and a seasoning liquid containing frozen ingredients is placed on top of it. I was

[0003] As such, for example, at least a layered structure composed of a first layer of a frozen seasoning liquid and a second layer of a frozen egg liquid, and the frozen ingredients are composed of a first layer, a second layer, and a first layer. It is included in at least one of the third layer different from the second layer, and is adapted to be heated and cooked in a state where the second layer is placed on the first layer during thawing cooking. (Japanese Patent Laid-Open No. 63-36)
No. 739).

By the way, when the above-mentioned bowl-type frozen food is thawed in, for example, a microwave oven at home, the seasoning liquid containing the ingredients thawed at an early stage soaks into the rice being gradually thawed. When the thawing is completed, the cooked rice will completely absorb the seasoning liquid and will have a texture like a swelling or a boiled texture as a whole, and the ingredients will also dry out It began to show a state of kogation due to lack of water, and when viewed from authentic rice bowls that come out when ordering at the store, it became quite inferior even in terms of quality, Most of them had a strong image of ready-to-eat foods, and most of them were not as good in terms of taste.

[0005] In order to solve the problems seen in such bowl-type frozen foods, various types of ready-to-eat foods in a container in which a solid food such as cooked rice and a seasoning liquid containing ingredients are separately stored have been developed. For example, a cup-shaped container for storing ingredients such as rice, noodles and eel, a bag-shaped container for storing ingredients such as curry soup and noodle soup, and an upper lid holding the bag-shaped container inside A container for a microwave oven, comprising: a bag-like container for accommodating the ingredient is made of an easily penetrable heat-shrinkable resin film, and a resin pin or the like on an upper lid holding the bag-like container inside. (Japanese Unexamined Patent Publication (Kokai) No. 4-369476) has been proposed an instant food container for a microwave oven, which is provided with a half-cut through hole.

However, in the instant food container, as described above, the bag-like container for accommodating the ingredients is formed of an easily penetrable heat-shrinkable resin film, and the bag-like container is placed on the upper lid holding the bag-like container inside. It is characterized by having a semi-cut through hole such as a resin pin, and the bag-like container containing the ingredients is automatically opened by microwave heating action, It is intended to pour ingredients into food ingredients, and it adopts a quite special configuration as described above, and at the same time, because the through hole is torn at a stretch and opened, the ingredients are uniform There was a surface that it was not always easy to put on foods in the state.

As described above, although many frozen foods have been developed at home or in stores, which can be immediately provided for food simply by thawing in a microwave oven, for example, rice, such as rice bowl, In the case of foods that combine dissimilar foods with remarkably different properties, such as seasonings with ingredients, the finished condition of the product after thawing is extremely unsatisfactory and comes out when ordering at so-called stores There is a problem in that it is technically extremely difficult to obtain a qualitatively high-quality one that is almost comparable to a full-fledged rice bowl, and there is a strong demand for technical improvement in the industry. Was in a situation.

[0008]

In view of such a situation, the present inventors have proposed a rice-shaped food product such as a rice bowl, in which a seasoning liquid and, if necessary, ingredients are placed on a solid food such as cooked rice. Eliminates the above-mentioned problems of frozen foods and develops high-quality products that can produce the same quality of frozen foods as a full-fledged bowl at a store. As a result of intensive research with the goal of doing so, use a specific form of inner lid that can store frozen seasoning liquid and ingredients as needed, and use a specific container that combines this As a result, the present inventors have found that the intended purpose can be achieved, and have completed the present invention.

The present invention relates to a frozen food in a container containing a solid food such as cooked rice, noodles and pasta, a seasoning liquid separately stored therefrom and ingredients as required, and In a new type of container that can be thawed in a microwave oven at home or in a store, and the seasoning solution and, if necessary, ingredients are placed evenly on the solid food immediately before eating, and immediately served for food. It is intended to provide frozen food.

[0010] Further, the present invention provides a simple and convenient method for preparing a seasoning liquid contained in an inner lid and, optionally, ingredients, after being thawed in a microwave oven, in a uniform state on a solid food such as cooked rice. It is an object of the present invention to provide a frozen food in a container that can be placed securely.

According to the present invention, a solid food such as cooked rice is loaded with an auxiliary solid food such as a fry, a tempura, a hamburger, a meatball, a fried egg and the like, if necessary, and the food is optionally placed on the solid food. For foods that are served in a uniform state with a seasoning solution containing ingredients and served as it is in a warm state, just thaw in a microwave oven, and there is no inferior to the authentic one that comes out when ordering at the store It is an object of the present invention to provide a high-quality frozen food in a container that can obtain a finished condition.

A perspective view showing a state in which the tubular flexible film 9 is extended downward and the lower opening d is opened is shown.

Of the substantially concave side wall e and the bottom b of the inner lid 3, a tubular flexible film 9 having an open lower part, for example, a PP film, is formed so as to be rollable from the bottom b to the lower opening d. It is necessary to provide the winding part a formed as described above. Further, the inner lid 3 is provided with a flange 10 around the periphery thereof for engaging with the opening of the container 1, and a small hole 4 can be provided as necessary. In the above inner lid 3,
The flange portion 10 may be of any shape as long as it is formed to have a width capable of engaging with the opening of the container 1, and has the same shape as that of the substantially concave side wall e and the bottom portion b of the inner lid 3. The structure and the like are not particularly limited.

The wrapping portion a is preferably formed, for example, by winding a tubular flexible film 9 having an open lower portion into an upward direction, but is not limited thereto. Any structure may be used as long as the film is wrapped in a certain direction, such as a film formed in a rolled state, a combination of the upward and horizontal directions, so that the film is squeezed in the horizontal direction. Any appropriate means can be adopted, and there is no particular limitation. In addition, the length of the entangled portion a also falls naturally on the upper part of the container 1 by its own weight when the seasoning liquid located at the bottom b of the inner lid 3 and the ingredient 5 as required extend the entangled portion a downward. When formed in such a manner that the side wall e and the bottom b of the inner lid 3 can reliably hold the seasoning liquid and the ingredient 5 as needed at that position when formed in a rolled state. It is not particularly limited as long as it is the one. Further, if necessary, an upper lid 6 having a vapor vent hole 7 provided on the upper surface of the inner lid 3 is fitted to the opening of the container 1 so as to be openable and closable.

The container in the present invention is preferably a cup-shaped, donburi-shaped or tray-shaped container having a certain height and an appropriate area in consideration of the above configuration. In addition, the material of the container 1, the inner lid 3, and the upper lid 6 to be used as necessary is, for example, frozen at the time of manufacture or heated by a microwave at the time of thawing.
The container 1 and the inner lid 3 need to have at least water resistance, and the container 1 and the inner lid 3 need to have more water resistance. Although required, any type may be used as long as such conditions are satisfied, and there is no particular limitation. Specific examples include paper, PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate), and the like, and these can be used alone or in appropriate combination.

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

Next, the seasoning solution and, if necessary, the ingredients 5 are put in an appropriate amount, and the frozen inner lid 3 is placed so as to cover the opening of the container 1, or the inner lid 3 is first placed on the container 1. After placing the container so as to cover the opening, a seasoning liquid and, if necessary, an appropriate amount of the ingredient 5 that has been frozen according to the shape of the inner lid 3 are stored. Finally, the upper lid 6 is placed by being fitted to the opening of the container 1 or the like, and if necessary, the whole is wrapped by a suitable wrapping means such as shrink wrapping to complete the frozen food in the container of the present invention. Further, as another manufacturing method, it is possible to appropriately set the solid food 2 before the freezing, the auxiliary solid food 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 thawing and opening operations of the frozen food in a container of the present invention by a microwave oven will be described. The frozen food in a container of the present invention is removed from the container in a microwave oven, if necessary, after removing the shrink wrap, removing the top lid, and then starting heating and thawing, and after a while, the frozen solid food 2, seasoning liquid (and ingredients) 5) and, depending on the food, 8 auxiliary solid foods
Begins to thaw, the moisture contained in the solid food 2 becomes steam, and convection begins in a 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 auxiliary solid food 8, and Since the bottom of the inner lid 3 is heated, the seasoning liquid (and ingredients) 5 is also heated as a result.

Further, since the steam gradually escapes from the small holes 4 provided in the inner lid 3 as necessary, the inner lid 3 does not come off due to the pressure of the steam. Further, when the upper lid 6 as shown in FIG. 3 is fitted, the vapor is applied to 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 occurs together with the steam generated from the water, and then the seasoning liquid (and ingredients) 5 is heated from above, and the 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 flange 10 of the inner lid 3 is lifted up. Flexible film 9
Is fully stretched by its own weight of the seasoning liquid (and ingredients) 5, the bottom b of the inner lid 3 communicates with the lower opening d. If the food is allowed to fall naturally onto the solid food 2 and the auxiliary solid food 8, the intended food that can be immediately served for food is completed.

As described above, according to the present invention, a bowl that is not inferior to a full-fledged bowl or the like that comes out when ordering at a store by simply thawing in a microwave oven and performing a simple operation. Not only foods such as foods, noodles and pasta can be easily prepared, but also the heating and thawing efficiency is extremely excellent compared to conventional frozen foods in containers, and the thawing time can be greatly reduced. Is obtained.

[0035]

The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the invention is limited thereto. Example 1 First, 100 g of cooked rice was put into a cup-shaped container (diameter 100 mm × height 100 mm, material / paper) so as to be flat, and subjected to a freezing treatment in a −40 ° C. freezer for 100 minutes. . Next, an inner lid, that is, a substantially flexible side wall and a bottom provided with a flange around the periphery for locking to the opening of the container, and a bottom of the inner lid, which is a cylindrical flexible member whose lower part is opened. Cover (height 40mm, polypropylene material) formed by winding a natural film upward
Is filled with 150 g of cooked seasoning liquid and ingredients for beef bowl, and is subjected to a freezing treatment in a freezer at −40 ° C. for 100 minutes, placed on the opening of the container, and then covered with an upper lid ( Cardboard) was fitted into the opening of the container to obtain a frozen food in the container.

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

The frozen foods in containers of Example 1 and Comparative Example were
Each of them was heated in a microwave oven of 500 W for 3 minutes, and in Example 1, the film was stretched downward by grasping the flange of the inner lid with a finger and lifting it up. Then, a comparative evaluation test was performed for both. As a result, the product of Example 1 was completely thawed, and the seasoning solution and ingredients were spread almost evenly and evenly on the cooked rice, showing a good finish condition, and the texture was extremely good. Yes, and it was as good as a full-fledged one at the store.

On the other hand, in the case of the comparative example, the central portion of the cooked rice is not yet thawed, the thawed portion has a texture as if cooked, and the ingredients such as green onions are dried. However, kogation was generated due to lack of water, the appearance was poor, and the taste was extremely poor. As described above, in the case of the frozen food in the container of the present invention, compared with the product of the comparative example, particularly, the seasoning liquid and the ingredients showed a good finish condition which was almost evenly and evenly spread on the cooked rice. , Which are positioned as unique effects not found in conventional products.

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 flat, and frozen in a freezer at −40 ° C. for 100 minutes. After the treatment, the frozen tonkatsu was separately placed on cooked rice. Then, separately, an inner lid, that is, a substantially flexible side wall and a bottom provided with a flange around the periphery for locking to the opening of the container, and the bottom of the inner lid is opened in a tubular flexible shape. Inner lid (40 mm high, polypropylene material) formed by winding the film upward
Filled with 150 g of seasoning liquid for cooked katsudon,
After being subjected to a freezing treatment in a freezer at −40 ° C. for 100 minutes, it is placed in the opening of the container, and then an upper lid (cardboard) is fitted into the opening of the container to obtain a frozen food in the container. Was.
As in the case of Example 1, a qualitatively high level product having a good finish was obtained.

Example 3 First, 100 g of spaghetti boiled by a conventional method was placed in a tray-shaped container (150 mm in width, 100 mm in width, 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. Next, separately, the inner lid,
That is, a cylindrical flexible film having a substantially concave side wall and a bottom provided with a flange for engaging with the opening of the container around the bottom, and the bottom of the inner lid being opened below the upper and lower sides of the flexible film. The inner lid (height 40)
mm, material polypropylene), and 150 g of the cooked napolitan sauce is filled in a freezer at −40 ° C.
The product subjected to the freezing treatment for 0 minutes was placed in the opening of the container, and then the upper lid (cardboard) was fitted to the opening of the container to obtain a frozen food in the container. The resulting product 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 auxiliary solid food, when thawed in a microwave oven, the thawed seasoning liquid does not soak into the solid food or the auxiliary solid food, and therefore, the solid food absorbs sagging. It does not give a fluffy texture or a boiled texture, break the clothes of the auxiliary solid food, etc., and dry and lack of moisture to cause kogation.

Further, when the solid food is thawed in a microwave oven, the vapor 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 is hardly dried and uniformly heated. The thawing time can be shortened as a whole, because the thawing liquid warms the seasoning liquid from below, and the thawing time can be shortened as a whole.

The inner lid placed so as to cover the opening of the container is formed in a state in which a cylindrical flexible film having the bottom part opened at the bottom is wound in a certain direction. So, after thawing in a microwave oven, when pulling up with the collar of the inner lid, the entangled part at the bottom of the inner lid extends downward by the own weight of the seasoning liquid and the ingredients as needed, and the seasoning liquid and the ingredients as needed , In the form of falling naturally by its own weight,
The food can be simply and reliably placed on the solid food in a uniform state, and as a result, dishes such as freshly made bowls, noodles, and pastas can be easily obtained.
