Description

[Detailed description of the invention] (Field of industrial application) This invention utilizes the exothermic or endothermic action of a chemical reaction between two types of substances to heat or cool drinks, instant foods, etc. This relates to a set of containers for heating and cooling used for heating and cooling.

(Prior art) When cooking instant foods (such as instant noodles) or boiling water in places where there is no heat source such as electricity or gas, such as in the fields or on the coast, a portable gas cylinder or oil is used as the heat source. Portable stoves are useful, but conventional portable gas or oil stoves are made of metal and relatively large, so they are heavy and require a large amount of space when being carried or stored. This resulted in problems such as inconvenience in handling and high manufacturing costs.

By the way, the present inventors mixed two types of substances, caused a chemical reaction between the two substances, and used the exothermic or endothermic effect generated during the chemical reaction to heat or cool drinks or instant foods. We have been diligently researching and developing devices that allow users to use their devices, and have already filed patents or utility model registration applications for some of them, but there is still room for improvement in terms of ease of use, cost, etc. It was hot.

(Purpose of the invention) In view of the above-mentioned circumstances, the present invention aims to provide a heating/cooling container set that is compact for carrying or storing, is easy to use, and can be manufactured easily and inexpensively. This is the purpose.

(Means for Achieving the Object) The heating/cooling container set of the present invention contains a chemically reactive substance such as an exothermic agent or a cryogen that causes an exothermic effect or an endothermic effect by chemically reacting with a reaction promoting substance such as water. a bottomless annular frame that is foldable and self-supporting when opened; an opening edge supported by the upper edge of the frame while housed in the frame; It is constructed in combination with a reaction container formed by a bag made of a film-like sheet that can mix the reactants.

(Function) The heating/cooling container set of the present invention has the following features: (1) Since the heating/cooling container set of the present invention is designed to generate exothermic or endothermic action through a chemical reaction between two types of substances inside the reaction container, fire is not used. (2) The reaction container and chemical reactant are combined as a set, making it easier to carry or use. (3) The reaction container is composed of a bottomless annular frame that is self-supporting when opened, and a film-like sheet bag housed within the frame. (4) The frame is foldable, and the bag is made of a film-like sheet. (5) The bag used to mix two types of substances inside is held in a self-supporting frame, Even if the bag itself does not have shape retention or self-supporting properties, by placing the bag together with the frame on a floor surface, etc., the shape and posture of the bag can be stabilized.

(Embodiment) An embodiment of the present invention will be explained with reference to Figs. 1 to 4. Figs. 1 to 3 show the first embodiment of the present invention, and Fig. 4 shows the second embodiment of the invention. A set of heating and cooling containers is shown.

The heating and heating of the first embodiment shown in FIGS. 1 to 3
The cooling container set consists of a chemically reactive substance B such as an exothermic agent or a cryogenic agent that chemically reacts with water (reaction auxiliary substance) A to produce an exothermic or endothermic effect, and a bottomless container that is foldable and can stand on its own when opened. The reactor 1 is composed of a ring-shaped frame 2 and a bag 3 made of a film-like sheet, and a heat-treated container 4 for containing a heat-treated material Y for heat treatment. In this embodiment, the heat treatment container 4 is also included in the set, but in other embodiments, the heat treatment container 4 is excluded from the set and the chemical reactant B is
It may also be configured with only the reaction vessel 1 and the reaction vessel 1.

When this heating/cooling container set is used for heating, an exothermic agent is used as chemical reactant B, and when this heating/cooling container set is used for cooling, an exothermic agent is used as chemical reactant B. Cryogens are used.

As the exothermic agent, for example, a mixture of calcium oxide, sodium bicarbonate (baking soda), and gypsum in appropriate amounts is used. Calcium oxide is the main exothermic agent, sodium hydrogen carbonate has the effect of delaying the start of the reaction between calcium oxide and water when they are mixed, and gypsum is the main exothermic agent. It has the effect of moderating the reaction rate of both (so-called retardation effect) when they are mixed together, and also of solidifying the reacted substances to some extent after the reaction. This exothermic agent is filled in an appropriate amount in a water-permeable nylon nonwoven fabric. The preferred ratio of each component of the exothermic agent is 250 parts by weight of calcium oxide,
10 parts by weight of sodium bicarbonate and 22 parts by weight of gypsum.

In addition, as a cryogenic agent, the main ingredients are organic acids such as malic acid, tartaric acid, and citric acid, and hydrogen carbonate compounds such as sodium hydrogen carbonate and potassium hydrogen carbonate, which have an endothermic effect when mixed with water. Use a mixture.

Chemical reactants B such as exothermic agents or cryogens
is sealed in a packaging material 5 made of a non-moisture permeable thin film material (for example, aluminum foil coated with resin on both sides), and when used, the packaging material 5 is torn to extract the chemically reactive substance B inside. Just do it.
Incidentally, by enclosing the chemically reactive substance B in the moisture-impermeable bag 5 in this way, the chemically reactive substance B will not absorb moisture and will not deteriorate over a long period of time.

The frame 2 of the reaction container 1 is flexible and foldable in the circumferential direction, and is formed into a bottomless cylindrical shape that is self-supporting when opened. The frame 2 is made of a relatively inexpensive material such as corrugated paper or cardboard.

The bag 3 of the reaction container 1 is water resistant and heat resistant (in the case of heating) so that water A and chemical reactant B can be mixed and a chemical reaction can occur inside the bag 3.
Manufactured from certain materials. For example, the bag 3 may be made of polyethylene resin, laminate film, or the like.

When this bag 3 is accommodated in the frame 2, the opening edge 3a of the bag 3 is inserted into the upper edge 2a of the frame 2.
It is attached by folding it back to the appropriate length on the outside. Of course, the bag 3 may be attached to the frame 2 by any suitable means.

When the reaction container 1 composed of the bag 3 and the frame 2 is packaged together with the chemical reactant B, it is folded into a small size as shown in FIG. If the bag 3 and the frame 2 are not attached to each other, they may be packaged in a folded state separately, and the bag 3 may be set inside the frame 2 during use.

The container 4 to be heat treated is made of aluminum and shaped into a shape-retaining box. An outward flange 4a is formed at the opening edge of the heat-treated container 4, so that the heat-treated container 4 can be hung on the upper lip of the reaction container 1 during use.

When packaging the reaction container 1 and the chemical reactant B, the packaging can be made more compact by housing them in the container 4 to be heat treated, as shown in FIG.

If water A for reaction to be mixed with chemical reactant B is preliminarily sealed in an appropriate amount in a pack according to the amount of chemical reactant B, it is convenient because there is no need to adjust the amount at the time of use. Further, if the water A for the reaction is made into salt water with an appropriate concentration, it will be difficult to freeze even in winter.

Next, a description will be given of how to use the heating container set of the first embodiment when, for example, dry noodles Y are heated and cooked.

When cooking, as shown in FIGS. 2 and 3, first the reaction container 1 (frame 2 and bag 3) is opened into a rectangular cylinder shape to match the shape of the heat-treated container 4, and then placed on the floor (the other side). ) on top of the packaging material 5.
The exothermic agent B inside is taken out by tearing it open, and the exothermic agent B is put into the bag 3 of the reaction container 1. When used on the floor of a house, a heat insulating bottom plate 6 is provided under the reaction container 1 as shown in FIG. It is recommended to provide a floor plate. Next, after putting the dried noodles Y and an appropriate amount of water W into the heat treatment container 4, the reaction water A is poured into the reaction container 1, and the heat treatment container 4 is quickly placed on the opening edge of the reaction container 1. If so, the key operation is completed. Note that a lid 7 is placed over the top of the container 4 to be heat treated, if necessary.

When reaction water A and exothermic agent B are mixed in the reaction container 1, a chemical reaction occurs between the two and an exothermic action is started. is heated to heat-process the food to be cooked (dried noodles) Y.

According to experiments by the present inventors, water A for reaction
100 ml of exothermic agent B formed at the above mixing ratio.
200g of the mixture was prepared and the two were mixed, and the resulting reaction heat was able to raise the temperature of 400ml of water at 15°C to approximately 93°C in 5 minutes.

When the cooking of the food to be cooked Y is completed, the cooked food Y is eaten with the heat-treated container 2 removed from the reaction container 1 or attached to the reaction container 1 as it is.

The container set of the first embodiment is disposable and can be disposed of at a designated disposal site after use.

Further, in the container set of the first embodiment, a heat generating agent is used to heat the food to be cooked and boil liquids (water, coffee, tea, etc.). If the exothermic agent is replaced with a cryogenic agent, it can be used to cool liquids (e.g. coffee, juice, etc.), fruits, etc.

The second embodiment shown in FIG. 4 shows a modification of the heat-treated container, and the heat-treated container 14 shown in the second embodiment is made of a single circular sheet material. As shown by reference numeral 15, they are folded back by an appropriate angle range and polymerized to form a conical container. Note that the folded portion (portion 15) may be fixed in a folded state in advance by means such as pasting.

In this second embodiment, the reaction vessel 1 has the same structure as that of the first embodiment, but in the case of this second embodiment, when the reaction vessel 1 is made to stand on its own, a conical cover is used. It is preferable to have a cylindrical shape to match the outer peripheral shape of the heat treatment container 14.

(Effects of the invention) The heating/cooling container set of the invention has the following effects.

(1) Since exothermic or endothermic effects can be generated within the reaction vessel 1 through chemical reactions between different types of substances, the reaction vessel 1 is It can be manufactured using inexpensive materials, and costs can be reduced.

(2) Since the reaction container 1 and the chemical reactant B are combined as a set, it is easy to carry and handle during use.

(3) Since the reaction container 1 is composed of a bottomless annular frame 2 that is self-supporting when opened, and a bag 3 made of a film-like sheet housed within the frame,
The reaction container 1 can be manufactured more easily and at a lower cost than in the case where the reaction container 1 is formed into a bottomed container shape.

(4) Since the frame 2 is foldable, and the bag 3 is made of a film-like sheet, it can be folded to make it compact when carrying or storing.

(5) Since the bag 3 is held by the frame 2 which has self-supporting properties, the bag 3 can be easily manufactured and inexpensive even if it is a bag-like product (without shape retention or self-supporting property). By placing the bag 3 together with the frame 2 on the floor, the shape and posture of the bag 3 will not collapse.
