Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a table heat insulation container.

(Prior art) Conventionally used for heating cheese fondue containers (pot)
Is heated with an alcohol lamp, gas, charcoal, an electric stove, a microwave oven or the like, and the amount of heat is adjusted to maintain a constant temperature.

Further, what can be used for keeping heat and cold by using a double container is known from JP-A-56-160950, JP-A-61-31325 and JP-A-60-72682. There is.

(Problems to be solved by the invention) As described above, when heating with an alcohol lamp, gas, charcoal, electric stove, microwave oven, etc. and keeping it at a constant temperature, the cheese burns and a fire is added to prevent it from burning. It's very difficult to adjust.

If you don't want to burn it and turn off the heat, the whole temperature will drop immediately and the cheese will solidify.

Therefore, since the hot state cannot be maintained, when cheese solidifies, bread, meat, vegetables, etc. are entangled with cheese and the taste is deteriorated.

Further, when the container (pot) is heated with an open flame, the cheese is burnt, and the cheese attached to the container (pot) cannot be easily put down, and cleaning is difficult.

This is because the temperature rises due to the direct fire and the proteins, etc. change violently and adhere firmly to the pan.

Moreover, using an open flame is dangerous to children and the elderly, and even if it is heated in a microwave oven, the temperature drops immediately when the heat source is removed.

Therefore, it is conceivable to keep warm and cool using a double container, but those of JP-A-56-160950 and JP-A-61-31325 disclose a heating agent between the inner container and the outer container. It cannot be used for heat retention repeatedly when the exothermic agent disappears, and the one disclosed in Japanese Utility Model Laid-Open No. 60-72682 cannot be used for heat retention only with cold food.

In addition, a pressure cooker composed of a double container is known as in JP-A-58-177612, but it cannot be used as a table container.

The present invention has been devised in view of the above points, and an object thereof is to obtain a table heat retaining container that can be used for both a direct fire and a microwave oven that can both keep warm and cool with a simple operation.

An open fire in this case is an alcohol lamp, gas,
Examples include charcoal and electric stoves.

(Means for Solving the Problems) In order to achieve the above objects, the container of the present invention is configured as follows.

That is, in the present proposal, a double container is formed with an inner tank and an outer tank made of pottery or heat-resistant glass that can be heated by an open flame or a microwave oven, and the inner tank holds food and the inner tank holds. The empty space between the outer tank and the outer tank should be of a size that can store hot water, cold water, ice, and / or a regenerator, and the inlet / outlet port of such a size that an ice block for cooling can enter the upper surface of this empty room. Is provided, and is configured with a detachable cap.

(Function) In the case of the present proposal, the cap of the inlet / outlet port on the upper surface is removed from the empty space between the inner tank and the outer tank, and hot water, cold water, ice and / or a cold storage agent is added to keep the food in the inner tank warm. Keep cool. The material forming the inner and outer tubs is earthenware or heat-resistant glass, which can be heated by an open flame and heated by a microwave oven.

(Example) An example shown in the drawings will be described below.

In FIGS. 1, 2, and 3, (1) is an inner tank, (2) is an outer tank, and these inner and outer tanks form a double container (7), and food is placed in the inner tank (1). The hot water, cold water, ice, and cold storage agent can be supplied from the pouring port (5) of the upper surface (4) of the empty chamber into the empty chamber (3) formed by the inner and outer tanks.
The spout (5) has a removable cap (6).
This double container (7) as a heat and cold container for the table is
There is a limit to the size of ice for cooling, and it is an ice block of a size that is usually used at home for cooking. The sizes of the vacant room (3) and the pouring port (5) can be adapted to the use of this ice.

Pottery and heat-resistant glass are used as the material for the container.

The cap (6) has, for example, a head (6a) made of pottery,
If the hem (6b) is made of Teflon or rubber, it is easy to put on and take off.

Foods that want to maintain hot temperature using the container of the present invention include cheese fondue, marbo tofu, stew, oden, sardine, curry, soup, and so on. , Jelly, bean paste, etc.

In FIGS. 4 (A) and (B), the cap (6) is removed from the pouring port (5) of the double container (7), and cold water is poured into the empty chamber (3) from the pouring port (5). It shows a state in which, for example, cheese and wine are put into the inner tank (1) of the prepared container (7).

Fig. 4 (C) shows the case where the material of the double container (7) is ceramics or heat-resistant glass, and the microwave (microwave oven) is used.
In (9), the state where the container (7) is heated with the cap (6) removed is shown.

In this state, for example, hot water at about 80 ° C is poured into the empty chamber (3), refrigerated cheese and wine are put into the inner tank (1), and heated in the microwave oven (9) to further bring the hot water to 90 ° C. The contents in the inner tank (1) can be heated and dissolved by raising the temperature to the upper limit.

After the dissolution, as shown in FIG. 4 (D), the double container (7) is provided with the cap (6) and is placed on the heat-insulating underlayment (8) with poor heat conduction. Place it on the table or use a weak open flame to prevent the temperature of the contents from falling, as shown in Fig. 4 (E). As the medium is used, the contents can be eaten by being wrapped in bread or the like without burning.

FIG. 4 (F) shows a state in which the double container (7) containing the contents is capped (6), placed on a heat-insulating underlay (8), and eaten after the completion of melting. .

5 (A) and 5 (B), after pouring hot water or cold water into the vacant chamber (3), for example, while heating the double container (7) with an open flame, cheese or wine is poured into the inner tank (1). It shows the state of being melted by throwing in.

After the completion of the melting, the double container (7) is kept warm with an open flame as shown in (C), or the cap (6) is provided as shown in (D) to provide a heat-insulating underlay. (8) The contents can be eaten by placing on top.

In any case, the container can be used through the order shown in the arrow direction.

In the above method, when hot water is put in the empty chamber (3) and wine, cheese or the like is put in the inner tank (1) and heated by an open fire or a microwave oven, the hot water temperature of the empty chamber (3) rises. Not only can it be cooked, but the cheese itself can also be heated at elevated temperatures, so the heating time is extremely fast.

Moreover, when a microwave oven is used, it can be heated without burning as compared with heating with an open flame, which is difficult to control.

It is also possible to put cooling water, ice water, or ice in the vacant chamber (3), or to freeze the whole with the vacant chamber (3) further filled with water and a regenerator.

In the above condition, cool the inner tank (1) with a salad,
You can put cold noodles etc. and eat while keeping the low temperature.

In addition, you can use powdered tofu as a food to put in the inner tank (1) and boil it, add a coagulant to make tofu, and use it without burning the contents. It is also possible to use a cooling storage agent containing the above for cooling.

(Effect of Device) According to the present invention, the following effects are obtained.

(1) As the material of the double container, use pottery or heat-resistant glass that can be heated by direct fire. Since hot water can be injected into the vacant chamber and used, the temperature rises above the boiling point (100 ° C) of the hot water. No heat, and since it does not become an open flame, the heated product does not burn. In addition,
If oil is used instead of hot water, it can be heated to 100 ° C or higher.

(2) Since hot water can be used for heat retention, the temperature drop in the inner tank can be significantly delayed.

(3) Since it does not burn, it is very easy to clean the container after use without any trouble.

(4) When hot water is put in the empty room and food is put in the inner tank for heating, since the double container is pottery and heat-resistant glass, it is possible to heat it in an open fire or in a microwave oven. Since the temperature of the vacant chamber can be raised and the food itself can be heated and heated, the heating time can be extremely short.

(5) It can be heated and kept warm in places where you do not want to use an open flame.

For example, in a restaurant where food is heated and kept until eating, cooking, etc., it may be necessary to keep the heat and heat for 20 to 30 minutes without a fire. In such a case, it is possible to heat and melt the food.

(6) Since the cap is on the upper surface of the vacant chamber, even if the cap is removed and hot water is poured from the pouring port and heated, steam escapes from the comparatively large pouring port, so there is no danger. Keeps you warm for a long time.

(7) Since the inlet / outlet is of a size that can be used to put ice blocks for cooling used at home, outside the cooling water, ice or ice water can be put in, and the object to be cooled is placed in the inner tank. It can be used as a cold storage container by putting it in a container and can be kept cold for a long time by applying a cap.

(8) In short, the present invention is a double container in which an inner tank and an outer tank are formed of a material that can be heated by direct fire of pottery, heat-resistant glass, or heated in a microwave oven. A pouring inlet with a size that allows ice for cooling to be placed on the upper surface of a container that has a vacant chamber, and a cap is attached to this, which can be used to keep warm and cool on a table, so it is easy It is characterized by its extremely high utility value due to its simple structure.
