Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention has a compact volume and good shelf life for use in eating out.
Simple Ka! The present invention relates to a water use heat generating material that can be erected and whose heat generating operation is simple, and a food heating storage container thereof. The above-mentioned conditions are required by the market, and if they are fully equipped, floor desks will be used in the restaurant industry, convenience stores, supermarkets, etc.

(2) Problems with the conventional technology The current heat-generating infusion containers on the market can be roughly divided into two types: a heat-generating material and a water storage bag are stored in two tiers at the bottom of the can, and either they are crushed with a bottle to generate heat due to hydration, or they are water-permeable. The heat-generating material is wrapped in non-woven fabric, placed in a plastic bag, and the attached tape pulls the threads to generate heat due to hydration, or water is poured to initiate a reaction to warm the food.

The first problem in this industry is that the heat-generating materials packaged with non-woven fabrics deteriorate rapidly due to air oxidation and do not have long-term storage stability.

In particular, when the inner partition or the bottom of the inner container is shaped like a slat to make it easier to heat the rice, it deteriorates particularly quickly and the performance cannot be maintained during use. There is a need in the industry for products that retain their performance and do not deteriorate even after being in stock for half a year. The second problem is that the adhesive attachment process of fixing one end of the tape and string for pulling the ice bag takes time and man-hours, resulting in low assembly yield and high costs. There is a desire in the industry for a container that can be assembled with one touch.

The third problem is that quicklime, metal oxides, magnesia cement, and their combinations each have a high exothermic temperature, and it is necessary to add excess water to these to prevent the plastic container from melting. As a result, storage containers are larger than food containers, resulting in higher container costs and occupying store display space, reducing sales efficiency. The industry desires compact containers. The fourth problem is a safe container that will never cause an accident to the user. Currently, if it is not reversed, it will explode, high-temperature steam will blow out from the hole where the thread or tape is pulled, and steam will blow out from the water injection hole as well. If the container is tilted during operation, the heat-generating material will be pushed to one side and the temperature will increase, causing an accident where the container may melt. The fifth problem is to solve the above problems and create an inexpensive container. Currently, it seems that we are purchasing containers that are more expensive than food products, and the functional price is not necessarily expressed.

(3) Method for solving the problems The root cause of the problems described above lies in the packaging of heat-generating materials and irrigation fluids, the way they are stored, and the means for hydrating them.

The first problem mentioned above is that as a means of blocking air and humidity, it is necessary to use a moisture-impermeable thin film, such as a synthetic resin film, aluminum foil, or a laminate of various films, and heat seal it or vacuum seal it to block the outside air. It can be solved by doing. The second problem lies in the method of contact between the heat generating material and the hydration solution, but if the heat generating material bag and the hydration solution bag are stored freely, the string or tape that crushes them must be fixed at one end. Furthermore, it is necessary to attach strings or tape to both the hydration solution bag and the heat generating material bag. Furthermore, various actions such as sealing with aluminum laminate film are added, increasing the number of man-hours and hindering production. The solution lies in a one-touch storage method. This is also related to the third problem, so I will explain it as well. One molecule of quicklime and one molecule of water produces a heat of 15.2-. That is, the water ratio is approximately 32 parts, producing a g equivalent of 270 cal.

Therefore, if heat is generated in a concentrated manner over a short period of time, the temperature may reach 300°C, so excess water is added to store heat in the water to control heat generation. The inventor has filed a patent application No. 62-32925.
As suggested in No. 5, if the temperature can be adjusted to the required temperature,
Since excess water is not required, the container can be made more compact.

The present invention has devised a method of integrally storing the heat generating material and the irrigation water, unlike the conventional methods of simply packaging the heat generating material and the irrigation water adjacent to each other or stacking each storage bag. The exothermic composition consists of solids such as powder, crushed materials, grains, briquettes, almonds, etc., and water as a reaction liquid or an aqueous solution as a mixture of inorganic and organic salts. In either case, the volume can be reduced by removing air, and by sealing by reducing the pressure. In addition, if the heat generating material and the ice bag are simply stacked together, the volume will be large and misalignment will occur, so it is possible to reduce the volume and create an integrated structure by backing up the bottom material of both sets together - especially by reducing the pressure. can. If the degree of vacuum is high, the packaging will be destroyed and the pressure will return to normal, increasing the infiltration of the reaction liquid and causing the exothermic material to hydrate and expand more than twice, further destroying the packaging and causing further reaction. is promoted. With simple packaging, it was necessary to pull the material with string or tape to prevent the reaction from occurring in its entirety unless it was crushed into large pieces.

Compacting begins with the reaction solution bag.

If there is excess air, it may break during depressurization and the volume will increase, so it is necessary to remove the air. Since the exothermic material is a solid substance, by reducing the pressure, there is no excess air and the volume is minimized. By stacking these double layers and heat-sealing them under reduced pressure, it was possible to integrate them into the minimum volume. Reaction solution bag, sure
The material was crushed, and the exothermic material was crushed at the same time, causing a rapid reaction. However, if double packaging is used, the initial infiltration of the reaction solution may sometimes be slow, so a sheet or film is pre-formed into the shape of a container saucer, filled with a heat generating material, and
The above-mentioned air-bleed reaction liquid bag was placed on top and heat-sealed under reduced pressure. An integrated plate was formed in the same manner as above. This was crushed with a protrusion to obtain the exothermic reaction described above. In this case, the reaction was not the same depending on the particle size and shape of the exothermic material. It is preferable that the protrusion is a small protrusion, like the tip of a bottle or knife, and is crushed. That is, if a large infiltration path is secured by small fractures, a rapid reaction occurs uniformly.

As a means to achieve this, the present invention provides
When a convex object is placed at a certain distance, for example, an almond with a thickness of 10% is placed in a compact machine crushed material (5% or less) and heat sealed under reduced pressure, a bridge space is created in this part and it is integrated. Molded. When this part was poked with the outer membrane/reaction liquid bag membrane and a crushing bottle, the liquid was instantly dispersed and the entire reaction occurred uniformly.

In the plate-shaped body integrated under reduced pressure in this way, the reaction liquid and the heat generating material were integrated without any movement.

As shown in Figure 4, a compartment was provided at the bottom of the storage container, and the integrated product was placed there, and a lower lip was attached to the partition plate in the same figure, and the partition was fixed with pressure at the same time as the partition was fixed.

As a result of the above, the integrated product was compacted by simply placing it in a compartment and fixing the partition plates to form the reaction solution into an integrated structure. The above-mentioned integral structure can also be molded so that the reaction liquid is brought to the edge and the exothermic material is covered with the agitating reaction liquid so as to be easily destroyed. Even if the water ratio is increased to a large extent and the excess amount is made separately, it is not outside the scope of the present invention. Next, I will talk about the fourth issue, safety. Consumers do not always use containers horizontally. If the heat-generating material moved, it would tip and concentrate the heat, causing the container to melt. If the reaction solution did not diffuse, the water ratio would be too low, resulting in overheating and a container melt accident. If you pull the string and tear the tape, high-temperature steam will blow out from the hole. Also, if the reaction solution is injected from the outside and the procedure is not taken to seal it, a similar accident will naturally occur. If the heat-generating material is vacuum packed and tightened as described above, it becomes a plate-like body and will not shift even if it is tilted.

The present inventor fixed the partition plate as shown in Fig. 4 to hold the tight integrated body of the exothermic material and the reaction liquid in a certain area and fixed it so that it would not fluctuate, no matter how it was tilted. No misalignment occurs.

Furthermore, this destruction must be done in one way, the crushing must be done reliably, and the sealing function must also be maintained. In other words, the tip of a crushing bottle may simply protrude, but it has a cutting edge with a slit similar to the tip of a harpoon or awl, and has a rotating slit that rotates to increase the crushing force and does not become clogged with crushed materials. Even better if you do. A bottle with a tip or cone-shaped protrusion, and the base has a tapered thickness sufficient to close the insertion hole when pushed in, and the length of the bottle does not allow it to be pushed in completely. As far as possible, the length is such that it does not crush the reaction solution and the heat generating material packaging at the same time, and furthermore,
The head is large enough to seal the insertion hole and act as an insertion stopper, and if there is a groove in the head so that the bottle can be pushed in securely, the bottle can be crushed more reliably by turning the screw with a coin. It would be even more effective if an elastic washer is provided between the head and the insertion hole to ensure safety.

The materials used in the present invention will be described below.

Heat generating materials include quicklime, magnesia cement, metal aluminum,
It refers to exothermic products from water use reactions whose main components are magnesia, iron oxide, etc., and the reaction solution also contains water, chlorides, mineral salts, chelating agents, and other water-soluble reaction regulators. .

That is, the exothermic material of the present invention is a general term for those whose main reaction is a water utilization exothermic reaction. The thin film that integrates the exothermic material and the reaction liquid refers to hard, semi-hard, and soft sheets and films, laminates of two or more layers thereof, and aluminum or laminate products formed by pressurizing, heating and pressurizing, or reducing pressure. This refers to products that can be further heat-sealed or vacuum heat-sealed. The heat generating material may be in any form such as powder, crushed material, press-molded material, almond, granular material, etc. The position where the exothermic material and the reaction liquid are integrated is arbitrary. The storage container is made of metal, PP,
ABS, PFiT, etc. 4° heat resistant resin or P
S, PB foam molded product or a composite product thereof, and its form is arbitrary. The partition board is made of synthetic resin or metal and is kept at 100℃.
It is desirable to have holes or slits that have the above-mentioned heat resistance and that allow heat-generating steam to flow through, but that are covered with a non-woven fabric so as not to stain the cooking rice. As shown in Fig. 5, it is inserted and fixed, fused, glued, or a combination thereof. Since the compacted integrated product of the exothermic material and the reaction liquid is shaped as described above, it is only necessary to store it in the molded compartment, and if it is pressed with the lip of the partition plate to leave a space, the integrated product can be closed. can be stored without moving.

An inner container can be used in place of the inner partition plate. Moreover, the inner container and the partition plate can be used together. The inner container may be made of plastic, aluminum, or a composite container with an aluminum bottom and a synthetic resin top. The aforementioned destruction bin is preferably made of plastic or metal.

The shape only needs to satisfy the above-mentioned conditions, and the shape shown in FIG. 5 is an example and is not limited thereto.

Function and effect of invention The functions and effects of the present invention will be illustrated by examples.

Example-1 When heating 250g of cooked rice in a 100g container to create a temperature difference of 50°C, if the calorific value per gram of the heating material is 250 can, then 350X50÷250=70
Tonaυ, the heating material quicklime is 70g and the water is 100% 70g.
All you need is cc. It was possible to integrate it to a thickness of 1.601 with a l0CFII angle. The film was made of nylon polyethylene laminate, and the vacuum forming was done using a machine manufactured by Nippon Polycello Industries. A heat-generating material and an ice bag were made in advance, and these were stacked and heat-sealed under reduced pressure at 750 mm.

When you disassemble a commercially available product, the heat generating material is 100g to 120g.
There was more than 100 cc of water, and the total thickness was about 51 mm, compared to 1.61 in the present invention.

In fact, when the product of the present invention was placed in a commercially available lunch box from Company A and heated, the rice reached 48°C, which was sufficiently warm.

Example-2 The inner partition of the commercially available Wappa rice type tea rice has many 2% holes, which are covered with non-woven fabric, but the heat generating material is also packed in a bag made of non-woven fabric, so the humidity of the tea rice makes it easy to prepare the rice the next day. The fever had deteriorated to an extreme degree.

70 g of the compact crushed heat generating material of the present invention and about 120 g of the compact crushed heat generating material of the present invention
80 cc of water at 11°C
The thickness of the corner was 1.8 degrees, % of the thickness of commercially available products. The exothermic peak of the integrated tightening material of the present invention is 180°C, but
After several months, the heat generated was 178°C, which was within the measurement error range and showed no deterioration.

Example-3 The heat generating material in a commercially available Shamai lunch box is 170g and 120cc of water.
Met. One of the two cases had a good fever on the day of purchase. Similar effects were obtained with 70 g of the heat generating material of the present invention and 70 cc of water, and the thickness could be stored in %. The other one on the market is
When the product was placed in the refrigerator and tested three days later, there was only a slight heat generation and no performance was observed.

Example-4 Aluminum-nylon laminate with a lie angle thickness of 1.8 (
Pre-form 8K, put 80g of compact crushed product of quicklime/magnesia cement mixture, place 1cys almond in the width of 1CIIk in the center, place a 100cc ice bag (adjustable insert) on top of it, and make Aiki style. It was heat-sealed using a vacuum forming machine under a reduced pressure of 700 mm. A bridge space as shown in Figure 3 was created between the almonds.

The thickness of the crushed product is 5 hairs and the thickness of almonds is 10? It became a bridge space for two demons.

Example-5 After molding as shown in Figure 3-1, 2, and 3, each part F was crushed by penetrating a part of the reaction liquid and exothermic material with a bottle with a tip, and then heat-sealed under reduced pressure. The exothermic material part returned to normal pressure and expanded, reaction water entered, a rapid reaction occurred, and the bag expanded, causing the bag to break and a complete reaction to occur. As for the exothermic material, compact crushed granules produced a more uniform reaction than powder, and solidified almonds produced a more uniform reaction. The molded sheet is PP and the heat seal is OP.
◎Example-6 Fig. 5 shows a fragmentary enlarged view of a crushing bottle used in the present invention with good results and its shape when crushed. Always store the crushing pin in the top lid.

Example 7 The inner partition plate was fixed by fitting holes and protrusions of the inner partition plate or the container, by hot-melt adhesion, or by electric welding of synthetic resins, all of which produced the desired strength. Further, ribs were provided at the lower part of the partition plate (Fig. 4), and at the same time as the partition plate was fixed, they served as pressure ribs to fix the integrated product.

Example-8 The inner container was used as a pressure fixing plate instead of a partition plate.
If it was a PP container and contained soup, it would not melt even if it came into direct contact with a heat generating material. The fitting was done by creating sitting ribs and protrusions on the inside of the outer container. (Figure 5) Example-9 Figure 6 shows an example in which all the devices of the present invention are installed.

Example 10 The crushing pin shown in Figure 5-1 is a PP type, and when the head is put into the upper lid as shown in Figure 7, it slides and breaks as shown in the figure, generating heat. When measured with a thermocouple, it reached 100℃ in 15 seconds.
Generates heat of 180℃ in 1 minute and 200℃ in 2 minutes and 30 seconds,
250g of tea rice reached 51°C in 3 minutes. The exothermic material is hard stone precious lime of Japanese Patent Application No. 62-329255, and 80 g of reaction solution is 69 times 80 cc of fresh water. The integrated product of the present invention used a polyester film and was molded into the shape shown in Figure 3.

Example 11 A 320 cc aluminum container was remolded into the container of the previous example, and oden was put therein and heated in the same manner. 70 in 5 minutes
It became ℃. I hope there are no problems.

Example-12 410 on a nylon polyethylene cylindrical film with a width of 7Q11
I added cc and sealed it. Thereafter, it was heat-sealed again into 5 equal parts to exclude air, and 5 bags of 80 g were obtained. 80 g of almonds measuring 24% in length x 16cm in width x 10% in thickness were placed in a preformed box-shaped product of 18X in thickness and 110% on one side so that there was a space of 2 cm in the middle. The 80 g ice bag described above was placed on top of it, an OPP film was placed on top, and heat-sealed under a 700 mm vacuum. A bridge space was created in the middle. Then set the bottle through the middle insertion hole. Figure 5: Put 300g of tea rice into a container and push it into the top lid of the bottle. After 4 minutes, I got tea rice at 55°C, and no steam spewed out.

5. Functions and Effects The heat-generating material maintains its performance if it is blocked from air and humidity, and in particular, there was no change in the performance of the hard stone precious lime of Japanese Patent Application No. 329255/1983 even after six months. The reaction solution bag was also molded under reduced pressure after removing air, and the bag was made of nylon laminate, which caused no trouble. When placed in the bottom section of the container of the present invention, which is an effect of the integrated product of the present invention, and with ribs attached to the partition plate, it did not move at all when pressed and fixed.

As mentioned above, the bridge space formed under reduced pressure by the convex objects absorbs the reaction liquid during crushing, and prevents a rapid reaction from occurring within the entire package and dispersing to the outside. Due to the action of the sealing pin of the present invention, heat was generated safely without any steam leakage. All installation can be done with one touch, and the storage container, lid partition, and pin can be manufactured in the same mold, streamlining mass production costs.

With the above, all of the first to fifth problems mentioned above have been solved.

The present invention relates to a hydrated heat generating material that is easily assembled and has a simple heat generating operation, and a storage container for heating food using the same, and has a wide range of applications in the restaurant industry, convenience stores, supermarkets, etc.

(Prior art and problems to be solved) The heat-generating containers on the current market can be roughly divided into two types: a heat-generating material and a water storage bag are stored in two tiers at the bottom of the can, and they are crushed with a bottle to generate heat due to hydration, or water-permeable containers are used. Wrapping the heat-generating material in a polyester non-woven fabric, attaching an ice bag stored in a plastic bag thereto, pulling the bag with tape or thread attached to the plastic bag, and pouring water onto the heat-generating material to generate heat by hydration; Or, the food is heated by injecting water to start the reaction.

The first problem with the above is that the heat generating material wrapped in the nonwoven fabric deteriorates rapidly due to air oxidation and has no long-term shelf life. In particular, when the internal partition or the bottom of the inner container is shaped like a slat to make it easier to humidify the cooked rice, the deterioration is particularly rapid, and it is often not possible to maintain the desired performance during use. Therefore, there is a need for products that retain their performance and do not deteriorate even after being in stock for half a year. The second problem is that the adhesive installation process of fixing one end of the tape and string for pulling the ice bag takes time and time, resulting in low assembly yield and high costs. Therefore, there is a need for a container that can be assembled with one touch.

The third problem is that quicklime, metal oxides, magnesia cement, and their combinations each have a high exothermic temperature, and it is necessary to add excess water to these to prevent the plastic container from melting. I have to.

As a result, storage containers are larger than food containers, resulting in higher container costs and occupying display space in stores.
Although it is reducing sales efficiency, more compact containers are needed. The fourth problem lies in the need for a safe container that will never cause an accident to the user, but at present, if it is not turned over, it may explode, or high and shallow steam may blow out from the hole where the thread or tape is pulled. A similar accident has occurred with steam blowing out from the water injection hole. If the container is tilted during operation, the heat-generating material will become heated to one side, causing an accident where the container melts. The fifth problem is that it is difficult to solve the above-mentioned problems and create inexpensive containers, but at present, it seems that we are purchasing containers that are more expensive than food products, so it is not always possible to reduce the functional price. Not expressed.

(Means for Solving the Problems) The root cause of the above-mentioned problems lies in the packaging of heat-generating materials and hydration liquids and the method of storing them.N) Means for hydration.

The first problem is that as a means of keeping air and humidity out, it is necessary to heat-seal or vacuum back-seal the laminate 1 of a moisture-impermeable thin film such as synthetic resin film, aluminum foil, or various films. This can be solved by increasing it to 111%. The second problem lies in the method of contact between the exothermic material and the hydration liquid, but if the exothermic material and the hydration liquid bag (packaged reaction liquid) are stored freely, one end of the string or tape that could break it will be fixed. Not only does the IJ have no leakage, but it is also necessary to attach strings or tape to both the hydration solution bag and the heat-generating material. Furthermore, various actions such as sealing with an aluminum laminate film are added, increasing the T number and hindering low-run production. The solution lies in a one-touch storage method. This is related to the third problem, so I will explain it here. One molecule of quicklime and one molecule of water - 1
Generates heat of 5.2 Kcal. That is, 32% hydration yields 1270 cal per 7 kg. Therefore, if heat is generated in a concentrated manner over a short period of time, the temperature may reach 300°C, so excess water is added to store heat in the water to control heat generation. If the present invention (1) can be adjusted to the required temperature as in the previously proposed Japanese Patent Application No. 62-329255, the container can be made more compact since no excess water is required.

The present invention improves the conventional method of simply packaging the heat generating material and hydration water next to each other or using separate storage bags to store them in one piece. That is, the exothermic material storage volume is (A), the reaction liquid storage volume is (B), and (14
) is the water ratio, and the area of the exothermic material and the reaction liquid together is (Y),
When the thickness is (P), the reaction liquid storage area at the same level as the exothermic material is (x), and the thickness at which the thickness exceeds (P) is (Q), the relational expression is as follows. Become. It is also possible to use X as a heat generating material and Y as a reaction liquid.

(I') Formula A=P (Y-X), B=PX+QY.

W=B/A becomes.

If P is 1 crn and has the dimensions of a square, then the CID formula Δ=
Since YI2-, X12, 13=XI2W= Δ 1+W −y y=X l2 W= y12−X12 , if the apparent specific gravity is 1, it is roughly estimated to be as in the vestibule.

Next, embodiments of this invention will be described.

(Example 1) In the above CI) formula, when A is 100 cc of aqueous solution, B is 80 g of heat generating material, and P is 1 crtr, the calculation results in 11 cm.
Inside the corner is a 4.58cm square and 0.59Ca thick l1cm.
It becomes a heat generating material in the corner. The shape is shown in Figure 2.

(Example 2) After molding as shown in Fig. 3 (2), (b), (C), and Fig. 4 (C), each part F is wrapped with a bottle with a tip and heated with the reaction solution 3. When a part of the packaging film 1a of the material 5 is passed through and crushed, the heat-sealed heat-sealed part returns to normal pressure and expands, and the reaction water enters, causing a rapid reaction and expanding, and the bag expands. It was destroyed and a total reaction occurred.

The heat-generating material 5 was more compactly crushed than the powder, and the almond solidified material 5a caused a more uniform reaction.

The molded sheet was a polypropylene film and the heat seal was OPP.

(Example 3) FIG. 6 is an enlarged front view of the crushing bin 8 that was used in the present invention and obtained good results. A closing plate 8affi is connected to the head of each crushing pin to close the hole. Usually, the crushing bottle is stored in the upper container.

(Embodiment 4) The inner partition plate 7 installed on the middle step of the outer container 12 in FIG. All of the electric welding of synthetic resins produced the desired strength. Furthermore, a rib 9 was provided at the lower part of the partition plate 7 (FIG. 5), and at the same time as the partition plate 7 was fixed, it served as a pressure rib to fix the integral stopper.

(Example 5) If the partition container 11 is provided outside the inner container 10 instead of the partition plate, and an appropriate space 15 is provided, the bottom surface of the partition container 11 will not come into direct contact with the exothermic material and will not melt. There wasn't. The fitting of the partitioned container 11 is carried out by means of a seated rib 1 on the inside of the outer container 12.
3 and protrusions 14 were made (Fig. 8). In the figure, 19 is a tearing thread.

The embodiment shown in FIG. 7 shows a state in which the crushing pin 8 is housed between the partition container 11 and the inner container 10.

(Example 7) The apparent specific gravity of the heat generating material is approximately 1 in powder form and approximately 1.0 in crushed product.
4. Since it is approximately 1.1 for an almond shape, it can be roughly calculated using the above formula. If the heat generating material is 80g and the water ratio is 70%, when the thickness is 1o, the first
It becomes a figure. If W is 120%, V2=13.26c
i X2=9.797cm and W is 50%
Then, from the same calculation, y3=10.954cm
It is compacted to X3=6.324CrR.

If the almond shape has a goodness of 2.5aR, and V+ = 10 law (from the IO formula, X4 = 5cm, the heat generating material is 80g as mentioned above, and W = 100% = 80g, then from the formula (1), B = From 80=52 +Qx102, Q=0.55, resulting in the shape shown in FIG.

With the calculation formula of the present invention, once the prerequisites are known, it becomes possible to freely create a compact design of an integrated structure of the exothermic material and the reaction liquid, which has not been previously proposed.

(Example 8) Next, the integration of the exothermic material and the reaction liquid will be explained.

As shown in FIGS. 4(a), (b), and (c), a heating material container 1 is formed by placing a heat-softened sheet or film on a mold, vacuum molding or pressure molding, and forming a recess in the container 1. 2 is filled with reaction solution 3 and sealed with film 4.

Next, the container 1 is turned over, filled with the exothermic material 5, and further heat-sealed with a film 6 to complete the process. Also, the 4th part, (e)
As shown in the figure, a heat generating material 5a may be placed in a container 1a, an enclosure 3a containing a reaction liquid 3 may be placed above the container 1a, and a film 6a may be used for 14 people.

Vacuum molding is optimal for heat sealing the heat generating material 5 of the present invention. If the degree of vacuum is high, the packaging will be destroyed, the pressure will return to normal, and the packaging will expand rapidly, increasing the penetration of the reaction liquid, and furthermore, the exothermic material 5 will hydrate and expand to 248 or more, destroying the packaging and further causing the reaction. promoted.

Also, the higher the degree of vacuum, the more compact it becomes. As described above, in the present invention, the exothermic material 5 and the reaction liquid are tightly molded into an integral structure in a plate-like body, thereby making the body compact. The integral structure can be formed by placing the reaction liquid 3 close to the end (Fig. 3 (a)), or by covering the agitating reaction liquid so that the exothermic material 5 is easily destroyed (Fig. 3)). ). Furthermore, the reaction solution 3 can also be placed above the heat generating material 5 (as shown in FIG. 3). The second and third problems have been solved by the above. Even if the hydration is made to a large extent and the excess amount is listed in a separate table, it will not be possible to create a skewer that is not within the scope of the present invention.

Next, I will discuss the fourth issue, safety. Consumers do not always use containers horizontally.

When the heat-generating material moved, it tilted and concentrated the heat, causing an accident that caused the container to melt. If the reaction solution did not diffuse, it would become too low in water, resulting in heating and a melting accident in the container. Pull the string or tear it with the tape; high-temperature steam will blow out from the hole. Also, if the reaction solution 3 is not sealed tightly when injecting it from the outside, a similar accident will naturally occur. As mentioned above, if you back up the heat generating material and tighten it, it will become a plate-like body,
It does not shift even when tilted. The present inventor fixed the partition plate 7 as shown in FIG. 5 to hold the tight integrated body of the exothermic material and the reaction liquid in a certain area and fixed it so that it would not fluctuate. There will be no misalignment. Furthermore, this crushing must be one-way, the crushing must be performed reliably, and the sealing function must also be maintained.

That is, the crushing bottle 8 may simply have a protruding tip, but
It is sufficient that the blade has a cutting edge with a slit similar to the tip of a harpoon or awl, rotates to increase the crushing force, and has a rotating slit that does not open the base with crushed materials. A bottle with a tip or cone-shaped protrusion, and the base has a tapered thickness sufficient to close the push-in hole rJ1 when pushed in, and the length of the bottle is such that it cannot be pushed in completely. Unless otherwise specified, the length is such that it will not crush the reaction solution and the heat generating material package at the same time, and the head is large enough to seal the insertion hole and act as an insertion stopper.
Furthermore, if there is a groove in the head so that the bottle can be pushed in securely, the bottle can be crushed even more reliably by turning the screw with a coin.

It would be even more effective if an elastic washer is provided between the head and the insertion hole to ensure safety.

(Example 9) Next, the materials used in the present invention were further coated. The heat generating material is
It refers to a hydration reaction exothermic product mainly composed of quicklime, magnesia cement, metal aluminum, magnesia, iron oxide, etc. The reaction liquid is water, chloride, mineral salts, chelating materials, and other water-soluble waterfowl reaction control. Refers to something that also contains wood. That is, the exothermic material of the present invention is a general term for those whose main reaction is a hydration exothermic reaction. The thin film that integrates the exothermic material and the reaction liquid refers to hard, semi-hard, and soft sheets and films, laminates of two or more layers thereof, and aluminum or laminate products formed by pressurizing, heating and pressurizing, or reducing pressure. This refers to products that can be further heat-sealed or vacuum heat-sealed. The heat generating material is powder, crushed material, press molded material, almond, etc.
The form of grains etc. is endless. The position where the exothermic material and the reaction liquid are integrated is arbitrary. Storage container is metal, PP, ΔBS,
It may be a heat-resistant resin of 100° C. or higher such as PET, a foam molded product of PS or PE, or a composite amount thereof, and its mode is arbitrary. The partition plate is made of synthetic resin or metal and has a heat resistance of 100°C or higher, and preferably has holes or slits that allow the heat-generating steam to flow through, but are covered with a non-woven fabric so as not to contaminate the cooking rice. As shown in FIG. 5, it is charged and fixed, F11 bonded, glued, or a combination thereof. Since the integral stopper for tightening the exothermic material and the reaction liquid is shaped as described above, it is only necessary to store it within the molded compartment, and if it is pressed by leaving a space with the rib of the partition plate, the said integral stopper is Objects can be stored without moving. An inner container can be used in place of the inner partition plate. Moreover, the inner container and the partition plate can be used together.

The inner container may be made of plastic, aluminum, or a composite container with an aluminum bottom and a synthetic resin top. The crushing bin 8
should be plastic or metal. The shape only needs to satisfy the above-mentioned conditions, and the shapes shown in FIGS. 6(9), (b), and (C) are examples thereof and are not limited thereto.

(Example 10) Next, in the example shown in FIG. 8, partition protrusions 16.16 are provided at predetermined intervals inside the bottom of the outer container 12, and the exothermic material 5 and packaging reaction liquid 3a are introduced inside the partition protrusions 16.16. The heat-generating composition materials 17 that are sequentially accommodated and packaged are accommodated. The partitioned container 11 is fitted onto the top of the heat generating composition 17, the inner container 10 is loosely fitted into the partitioned container 2S11, and the lid 18 is placed over the top of the outer container 12. 19 in the figure is the partition container 11 and the outer container 12
The crushing thread is guided to the outside through the gap between the thread 1 and the thread 1.
By subtracting 9, the packaging film 20 of the heat generating composition material 17
can be broken.

When the packaging film 20 is torn in this manner, the reaction liquid (for example, water) comes into contact with the exothermic material to generate reaction heat, and the inner container 1
Warm the items within 0 appropriately.

Next, the present invention will be explained with reference to usage examples.

(Use example 1) When heating 250 g of cooked rice in a 100 g container to create a temperature difference of 50°C, if the calorific value of the heat generating material is 250 cal per g, then 350 x 50 ÷ 250 = 70
Therefore, the heat generating material should be 70g and the water should be 100% 7Qcc. Therefore, assuming that it is a square, if the overall thickness is 1 cm, there will be 8.37 in 11.83 cm on one side.
All you need is α square water.

When you disassemble a commercially available product, the heat generating material is 100g to 1209g.
The temperature of the water was 100° C. or more, and the total thickness was 3C11 or more, compared to 1 cm in the present invention.

In fact, when the product of the present invention was placed in a lunch box and heated, the rice reached 48°C, which was sufficiently warm.

(Usage example 2) The inner partition of commercially available Wappa rice type tea rice has many holes in 2, which are covered with non-woven fabric, but since the heat generating material is also packed in a bag of non-woven fabric, it is difficult to use when cooking rice wet. The next day, the fever had worsened to an extreme degree.

70g of heat generating material of the present invention and 80cc of about 120% water -
・The body stopper was 12.24 cr R square with a height of 1 cm and a commercially available thickness of 173 mm. The exothermic peak of the tightening and fixing agent of the present invention was 180°C, but the exothermic value after 6 months was 178°C, and there was no deterioration within the measurement error range.

(Effects of the Invention) In this invention, since the exothermic material and the packaged reaction liquid are packaged integrally and tightly, the product is compact and compact, and if necessary, the reaction heat can be easily obtained by bringing the two into contact with each other. I can do it. Further, by housing the heat-generating composition and the inner container as described above in the outer container, there are various effects such as the ability to make the heating container more compact.
