2. Description of the Related Art Conventionally, when heating, thawing, and cooking with a high-frequency heating device such as a microwave oven, the optimum heating temperature varies depending on the food item. In general, it was common to study the type and amount of food, the food temperature before heating, etc., and cook while appropriately determining the heating time.

In order to make up for each of the above-mentioned drawbacks, various improvements have been made to the high-frequency heating device itself in the past, such as temperature sensors,
High-frequency heating devices with built-in humidity sensors, infrared detectors, etc. have been developed. However, in the above high-frequency heating device, no matter how the optimum temperature of food is obtained by various sensors, etc., the optimum heating temperature is different for each food item. I couldn't cook multiple foods at the same time.

Further, even when heating one kind of food, it is impossible to properly heat different foods by keeping the heating time constant because the heating time must be set according to the food.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a control member for adjusting the amount of transmission of electromagnetic waves constitutes a part or all of the container, and the control member is provided on the lid of the container such as a lunch box or on the side surface of the container. By sticking together, it is possible to simultaneously heat foods with different optimum heating temperatures such as meat, vegetables and rice without changing or adjusting the heating time for each food item, just by setting the constant heating time. To be able to thaw and cook,
Even if it is a single product, it is not necessary to set the heating time according to the food.

That is, the present invention is intended to reduce cooking time and labor by a high-frequency heating device such as a microwave oven.

According to the present invention, a control member 3 having a hole 2 of an appropriate shape for transmitting an electromagnetic wave is provided on a base material 1 for limiting the transmission of an electromagnetic wave such as a microwave. Further, it is configured as a container in which all or part of the control member 3 is configured, and a container in which the control member 3 is attached to all or part of the control member 3.

Further, a container in which all or a part thereof is constituted by a plurality of the control members 3 having different electromagnetic wave transmission amounts, and a container in which a plurality of the control members 3 having different electromagnetic wave transmission amounts are attached to all or a part thereof. Is configured as.

[0009]

The present invention has the following actions. The shape and size of the holes 2 provided in the base material 1 are appropriately set according to the optimum heating amount of the food item to be heated and thawed. Thereby, even if the output itself of electromagnetic waves such as microwaves radiated from a magnetron such as a microwave oven is constant, it is provided on the base material 1 made of a material (aluminum, alumina, etc.) that limits the transmission of electromagnetic waves. The amount of transmission of electromagnetic waves such as microwaves per unit time is limited depending on the area and shape of the hole 2. Therefore, if the area and shape of the hole 2 are adjusted in advance according to the optimum heating temperature and amount of the food item put in each partition 6 of the container body 5, it is not necessary to change or adjust the heating time for each food item. It is possible to heat, thaw, and cook many food items at once by simply setting a fixed heating time. Further, even a single product can obtain a heating amount according to the food by a fixed heating time, so that it is not necessary to study the heating time.

To be done. FIG. 3 is a perspective view of the food container 4 (lunch box) to which the film-shaped control member 3 is attached.

In this embodiment, the material of the container body 5 and the lid 7 is made of a plastic that transmits electromagnetic waves, the container body 5 is divided into two parts by partitions 6, and the film-shaped control member 3 is attached to the upper surface of the lid 7. Although the partition 6 is provided, the partition 6 in this case may partition the container body 5 into three or more places. The film-shaped control member 3 attached to the upper surface of the lid 7 is divided into positions corresponding to the partitions 6 of the container body, and the electromagnetic wave transmission amount of microwaves or the like per unit time of each division is determined by the container. The optimum heating temperature of the food put in each partition 6 of the main body 5,
For example, meat is 110 ° C, rice is 60 ° C, and vegetables are 15 ° C.
The values are set according to ° C and 0 ° C for ice cream.

That is, in this embodiment, since the film-shaped control member 3 which is divided corresponding to the partition 6 of the container body 5 and whose electromagnetic wave transmission amount is adjusted has a plurality of adjusting functions, the microwave from the magnetron is used. Even if the radiation is always constant, it is designed to obtain a heating amount suitable for separate foods. In this embodiment, the film-shaped control member 3 is attached on the upper surface of the lid 7. However, since the lid 7 is made of a material having a property of transmitting electromagnetic waves, the back surface of the lid 7 that is close to foods. The film-shaped control member 3 may be attached to the container, or when the container body 5 is partitioned in parallel with the side surface, or the microwave oven is a model that radiates microwaves from the side. In this case, the film-shaped control member 3 may be attached to one side surface which is an electromagnetic wave irradiation side.

However, regardless of whether the film-shaped control member 3 is provided on the lid 7 or the side surface 8 of the container body, the film other than the surface on which the film-shaped control member 3 is provided, that is, the lid 7. When the shape control member 3 is provided, the four sides of the container body 5 are provided, and when the film control member 3 is provided on one side of the container body 5, the lid 7 and the other three sides of the container body 5 are provided with an appropriate heating amount of food. In order to achieve this, it is preferable to block electromagnetic waves such as microwaves with a material that reflects and absorbs them, and to prevent transmission of microwaves.

Further, in this embodiment, the film-shaped control member 3 is attached to one surface of the lid 7 or the container body side surface 8, but the film-shaped control member 3 is provided on the entire surface of the lid 7 and the container body side surface 8. It is also possible to attach it. FIG. 4 is a perspective view of the food container 4 having the film-shaped control member 3 as the lid 7. In this embodiment, the inside of the food container 4 is not partitioned, and the film-shaped control member 3 is attached to the upper edge portion 9 of the food container 4 by the lid 7.
It is affixed as, and has a structure in which a plurality of these are connected in series.
A cutting line 11 is provided on each continuous portion 10 so as to be easily divided.

The food containers 4 contain foods of different items, and the amount of permeation of microwaves etc. of the film-shaped control member 3 which is also the lid 7 of each food container 4 according to the optimum heating amount of the foods. Is set. Therefore, as a result of constructing the embodiment of FIG. 4 in such a manner, it becomes possible to simultaneously heat, thaw, and cook the food containers 4 with the high-frequency heating device such as a microwave oven in a state of being connected in series. The user can prepare meals for a large number of people at the same time, and since it is possible to select only the food container 4 containing the favorite food and cut it along the cutting line 11 to cook, the meal according to the taste It has the merit of being able to take

FIG. 5 is a perspective view showing an embodiment using a plate-shaped control member 3. That is, in this embodiment, the control member 3 having the same thickness as that of the container body 5 is used as the original fabric, and the lid 7 is formed by a method such as vacuum forming. And, similarly to the embodiment shown in FIG. 3, it goes without saying that the electromagnetic wave transmission amount is set so that the control member 3 which is the lid 7 also performs two different adjusting actions depending on the partition 6 in the container body 5. .

Therefore, according to this embodiment, it is possible to simultaneously cook a large number of food items having different optimum heating amounts. Further, in this embodiment, the film-shaped control member 3 is not attached to the lid 7. Since the control member 3 itself is molded on the lid 7, there is no risk of the film-shaped control member 3 peeling off due to repeated use of the food container 4. In addition, the above-mentioned FIGS.
In the above embodiment, the control member 3 is exclusively used for heating, thawing and cooking food, but it is constructed as a whole or a part of the container used in the method invented as a substitute for the freeze vacuum drying method. It is also possible.

That is, there is already known a known method for drying foods, which comprises a depressurizing process, a pressurizing process, and a high-frequency dielectric heating process, utilizing the characteristics of a microwave oven or the like for heating the water in foods. (See Japanese Examined Patent Publication No. 64-6392), which coexists with the conventional freeze-vacuum drying method. Therefore, if a container having a plurality of control members 3 having different electromagnetic wave transmission amounts attached thereto or a container having a plurality of control members 3 having different electromagnetic wave transmission amounts is used in the above food drying method or the like, a plurality of different types can be obtained. It is also possible to dry foods and the like at the same time. In FIG. 6, the grid-like control member 3 is attached to the lid 7.
FIG. 3 is a perspective view of the food container 4 described above.

As described above, the role of the hole 2 in the present invention is provided only for transmitting electromagnetic waves, and therefore the shape of the hole 2 is basically not limited.
Therefore, as in this embodiment, the base material 1 is formed in a lattice shape,
It is possible to form the control member 3 by arranging the square holes 2 regularly, but not only that, but the control member 3 can also be formed in the lattice shape as in this embodiment. It shows that it can also be used for food containers for microwave cooking.

That is, a food container for microwave cooking in which a container is composed of a package material composed of a base material layer, a conductive element metal layer, and a protective layer, and which can heat food to a brown color is already known in the art. Exists (Japanese Patent Sho 60
(See Japanese Patent Publication No. -15548), by using the packaging material and the container together with the control member 3 having a lattice shape, a stripe shape, or the like,
It becomes possible to easily cook a food such as fish which is preferred to have a brown brown color, in a desired state, for example, in a grid-like brown texture.

Also in this case, of course, by using a plurality of control members 3 having different electromagnetic wave transmission amounts, it is possible to simultaneously cook a plurality of different types of food such as fish in desired states. In each of the embodiments shown in FIGS. 3 to 6, the upper surface of the lid 7 can be subjected to other processing as long as the function of controlling the amount of transmission of electromagnetic waves of the control member 3 is not hindered. Is. For example, it is possible to print a trademark name, a right holder's name, etc. on the upper surface of the lid 7 with ink or the like that transmits electromagnetic waves, or to draw a flower pattern, a cartoon character, etc.

[0025]

According to the present invention, the amount of transmission of electromagnetic waves can be adjusted appropriately and simultaneously by the control member for limiting the transmission of microwaves and the like and the container using the control member. Therefore, the heating time for each food item can be adjusted. There is no need to consider changes or adjustments.

Therefore, if a constant heating time is set in advance, it becomes possible to simultaneously heat, thaw, and cook meat, vegetables, rice, etc. having different optimum heating temperatures, and even if it is a single product, It is not necessary to consider the heating time. Therefore, according to the present invention, it is possible to reduce the cooking time and the labor of the cook by the high-frequency heating device such as a microwave oven.
