Abstract

The present invention provides a heating apparatus having a structure wherein an opening of a lower water bag (107) storing therein water and an opening of an upper heating bag (108) storing therein a heat generating agent causing the hydration are arranged to face each other and both the openings are sealed with a covering material. The invention provides a heating container for foodstuffs using the apparatus. To use the apparatus, an open seal tape (109) for tearing or peeling the covering material from outside is pulled out to open the openings, whereby water flows out uniformly and reacts with the heat generating agent and steam generated thereby heats uniformly the goodstuffs. A closing member (104) disposed over a pull-out hole (102e) through which the open seal tape (109) is pulled out undergoes deformation towards the container due to the heat and seals the container. Accordingly, heating efficiency can be improved and blow-out of the high temperature steam can be prevented.

Description

Description Heating device and heating vessel using the same (Technical field)

The present invention includes a heating device that can easily heat food and drink by utilizing a reaction heat generated by a hydration reaction between water and a heating agent, and an envelope that houses the heating device. Related to heating vessels.

(Background technology)

Take-away foods with over-the-counter cooked foods As a device that easily heats food and drink such as coffee and black tea, a heating device in which the food container and the heating container are placed in a non-contact state in recent years is often used. It has been done. For example, there has been known a heating apparatus in which food is partitioned and integrally incorporated into a heating container for storing food (see Japanese Patent Application Laid-Open No. 61-2599774). Generally, this type of heating device separates water and quick lime by inducing a liquid such as water and a heat generating substance such as quick lime, respectively, by passing a framing rod through the cell and breaking the cell. On the other hand, in the latter case, in the latter case, the water flowing out by rupture of the water bag is brought into contact with quicklime to obtain the heat of reaction from the hydration reaction.

In addition, there is known a heating container in which a water bag is arranged in the center of the heating container, and a heating agent is stored around the water bag (see Japanese Utility Model Publication No. 62-3250000). When using this type of heating vessel, break the frame rod or pin into the container. By breaking the compartment or bursting the water bag, water and the heat generating agent are brought into contact with each other to obtain the heat of reaction due to the hydration reaction and heat the object to be heated.

(Technical issues for Kishiaki to decide on tanning)

However, in the above-described conventional heating apparatus, when a skewer is inserted into the compartment to bring water into contact with quick lime, it is possible to easily cause a hydration reaction, but there are many cases in which the skewer is around the smashed frame. Water flowed out, resulting in a non-uniform hydration reaction zone. Therefore, when heating a flat box-shaped container such as a lunch box, heating steam is appropriately generated in the area where a large amount of water is provided, but in the surrounding area separated from the water outflow area. However, since the penetration of water was small, the generation of heated steam was uneven, resulting in uneven heating. In addition, in areas where water intrusion is low, the heat of reaction of quicklime is not consumed for water evaporation and may become abnormally hot.In containers that must be held in hand, such as food containers, burns may occur during use. There was a danger of producing. On the other hand, when the water bag is broken, the hydration reaction region can be made uniform, but if the water bag is arranged above the heating bag, the ruptured water bag is almost on the upper surface of the heating bag. Since it remains in its original form, it becomes an obstacle to hinder the rise of heated steam due to the hydration reaction, and the problem of reducing the heat transfer effect remains.

In view of the above, the present invention has been made in view of the above-mentioned problem. When a water container and a heat agent are hermetically sealed in a container を, the containers are simultaneously opened to hydrate the water and the exothermic agent. Accelerated reaction The first objective is to improve the heat transfer of reaction heat due to the generation of heating steam.

On the other hand, in the case of a conventional heating vessel, when a frame rod or a pin is inserted into the heating vessel, the hydration reaction can be easily caused, but in the former case, a through hole is provided in the vessel. As a result, some of the high-temperature steam generated by the hydration reaction leaks out of the container through the through-hole, and burns when used in containers that must be held in hands, such as food containers. There is danger. On the other hand, in the latter case, a seal tape is attached to the through-hole communicating with the inside and outside of the heating vessel, but since this seal tape is peeled off when used, it has expanded due to the heat of reaction accompanying the hydration reaction. Since high-temperature air is blown outward from the through-hole, there was a danger during use in the same manner as described above. In addition, leakage of high-temperature steam and escape of high-temperature air always involve heat loss, which reduces the heating efficiency of the heated object and is uneconomical.

Accordingly, the present invention has been made in view of such a problem of steam, and prevents high-temperature steam generated by a hydration reaction from leaking from a heating device to the outside of an envelope, thereby avoiding a danger such as a burn. The second purpose is to reduce heat loss.

(Disclosure of the Invention)-In order to achieve the first object of the present invention, the present invention includes a water container and a heating agent, and the water container has an opening surface of a water container body capable of storing water therein. The heating agent is covered with a coating material. If necessary, the heating agent container body capable of accommodating therein the heating agent that generates heat by the hydration reaction, and the opening surface of the heating agent container body are covered. It is covered with a covering material, and a part of the covering material of the water container or, when the water container and the ripening agent are enclosed in the container, the opening surfaces of the water container and the ripening agent are arranged facing each other, and the covering of both containers is performed. It is characterized in that the heating agent container can be opened together with the water container, if necessary, by stretching the material.

The present invention provides, in order to achieve the second object, a container provided with an envelope for accommodating an object to be heated and a heating device generating heat by a hydration reaction, wherein the plastic sheet faces a heat source. It is characterized in that a closing member formed by utilizing the property of deforming covers the opening communicating with the inside and outside of the envelope and is fixed to a part around the opening.

(Action)

According to the first configuration described above, when the material to be covered covering the opening surface of the water container body is pulled, the coating material is ruptured or peeled off, and the water container is opened. The water in the water container flows out and comes into uniform contact with the heating agent, causing a hydration reaction. When the chemical is heated by this chemical reaction, the generation of heated steam is promoted and the object to be heated is uniformly heated. If the exothermic agent is enclosed in the container, pulling one end of the covering material of the water container and the exothermic agent container arranged with the opening surfaces facing each other will cause the covering material to rupture or peel off and to be separated from the water container. The exothermic agent container opens simultaneously. The water in the water container flows out and comes into uniform contact with the exothermic agent, causing a hydration reaction. When the exothermic agent ripens due to this chemical reaction, the generation of heated steam is accelerated, and the object to be heated is evenly ripened. Further, since the water container body contracts due to the high temperature caused by the generation of the heated steam, the rise of the high-temperature steam is not hindered, and the heat transfer to the object to be heated is properly performed.

On the other hand, according to the above configuration, when the water in the water bag is brought into contact with the heating agent to cause a hydration reaction, high-temperature steam is generated from the heating device. At this time, when a part of the high-temperature steam is fixed to a part of the periphery of the opening of the envelope and a part of the high-temperature steam touches the closing member covering the opening, the closing member is formed of a plastic sheet. Deforms to the heating device side. As a result, the closing member is in close contact with the side wall of the envelope to close the opening, thereby preventing leakage of high-temperature steam.

In the present embodiment, the heating device 1 is of a cartridge type and is detachably housed in a container body 11 described later. The used heating device 1 is replaced with an unused one. As a result, the food container 10 can be reused and has a structure. The heating device 1 may be disposable by being integrated with the container body 11.

As shown in FIGS. 1 and 4, the food container 10 is provided with an inner container 12 for storing food inside a container body 11 which is a flat box and can be opened and closed by a lid 13. The ripening device 1 is arranged below the inner container.

The container body 11 is a flat box with an open top and made of foamed stick, and has a partition 11b at the bottom that protrudes inward from the bottom plate 11a. Surface formed I have. An opening 11 d is provided in one side wall 11 c of the container body 11 adjacent to the opening 2 a formed in the heat insulating container 2 of the heating device 1, and the rain openings 2 b and 1 1 are provided. The opening tapes 5a and 6a are drawn out through d.

As shown in Fig. 1, the bottom plates 14a and 15a of the heating section have a wavy cross section and a dog surface area, and are configured to effectively conduct heat. Further, a plurality of slit-like steam discharge holes 14b, 15b are formed in the bottom plate so that heated steam can be discharged from below to the heating sections 14, 15 內. Further, at the top of the partition wall 18 between the first heating section 14 and the second heating section 15, a slit for discharging ripened steam to the first heating section 14 from above is provided. A vertical water vapor discharge hole is formed. --The non-heated part 1S stores side dishes F that do not need heating and are cool in the cold state. Small compartments are formed in the compartments 16a and 16.16c. When the inner container 12 is set in the container body 11 in the prone position, the non-heating section 16 is provided with the heating device housing section by the partition 11 of the container body 11 as shown in FIG. The structure is completely separated from 9 so that it is not affected by the heat from the heating device 1.

The isolation wall is formed in a plurality, and is provided between the first heating unit 14 and the second heating unit 15 and between the second heating unit 15 and the non-heating unit 16. Concave portions 18b, 17a are formed in the partition walls 18, 17 respectively, and partition ribs 13c, 13d of the lid 13 described later are fitted into the concave portions. It can be stopped. · The lid 13 is made of plastic integrally molded in the same manner as the inner container 12, and has a fitting portion 1 on the outer periphery する which is fitted to the fitting portion 12 a of the inner container 12 in a covered manner. 3a is formed, and has an inner contact surface 13b that contacts the top surface of each of the isolation walls 17 and 18 of the inner container 1. Accordingly, in a state where the lid 13 is provided on the container body 11, the contact surface 13 b-... Comes into contact with the top surface of each of the isolation walls 17 and 18 of the inner container 12. Each of the heating sections 14, 15 and the non-heating section 15 is a sealed space completely isolated from each other.

Thus, when using the food container 10 configured as described above, the inner container 12 is set in the container main body 11 and then the respective storage portions 14, 15, and 16 of the inner container are set. Put rice D, side dishes E, and F into the container respectively, and cover the lid 13 with the lid 13 on top of the container body 11. And for example, after a few hours this food container When eating the foods D, E, and F stored in the food container 10, the heating device 1 installed in the food container 10 is operated to operate the heating units 14 and 15 of the food. Heat only foods D and E

Next, the heating operation of the heating device and the food container will be described.

Pull the opening tape 5a, 6a facing the outside of the container body 1 1 in the direction of the arrow in Fig. 1, and mark 5c, 6c indicating the separation limit of each coating material 5, 6 to the outside. Pull out until exposed. At this time, the respective substrates 5 and 6 adhered to the opening surfaces 3 e and 4 e of the exothermic agent container 3 and the water container 4 receive the tensile force, and the base portions 5 of the opening tapes 5 a and 6 a receive the tensile force. b, § Peel from the b side. Each covering material 5, 6, heating container body 3 a, is only is bonded to the peripheral edge of the water container body 4 _a, moreover tear tape 5 a, 6 a is a group嫱部5 b, 6 b, Since it is folded back, tensile force acts on the 嬙 side of coating materials 5 and 6. Therefore, both coating materials are easily separated, and the ripening agent container 3 and the water container 4 are simultaneously opened. As a result, the water 8 contained in the water container 4 flows out and comes into contact with the quicklime 7 in the hot water container 3, causing a hydration reaction to cause the above heating. At this time, since the water container 4 is arranged on the upper surface of the ripening agent container 3 and has heat shrinkage, it is shrunk rapidly by receiving the high temperature of the ripening steam over substantially the entire surface. As a result, the heated steam is sent from the filter 2 c of the ripening vessel 2 to the heating sections 14 and 15 of the inner container 12 via the steam discharge holes 14 b and 15 b of the vessel 12. , Food D, E heat.

That is, the rice D in the first heating section 14 is heated not only from below but also from above, while the side dish E in the second heating section 15 is heated only from below. , Is kept at a suitable temperature. The heating device of the present invention can be applied not only to heating of food containers such as the lunch box of the above-mentioned embodiment but also to heating of canned foods and the like. Also available.

In the above embodiment, the case where the heating agent 7 is sealed in the container 示し is shown. However, as shown in FIG. 5, the heating agent 7 is capable of penetrating into the inside like a non-woven fabric having high water absorption. Alternatively, it may be packaged in a sealed bag material that is opened simultaneously with separation of the coating material 6 of the water container 4. The same members have the same reference numerals and description thereof will be omitted.

As described in detail above, according to the heating device, the opening of the water container and the heating agent container are faced to each other by pulling the coating material covering the opening surface of the water container. The water container and the ripening agent container are simultaneously opened by arranging and pulling the covering material covering each opening surface, so that the water comes into contact with the hot water agent evenly, Since the heated steam is generated in the entire area of the exothermic agent container, the object to be heated is uniformly and appropriately heated. In addition, the problem of abnormally high temperature caused by a small amount of water supplied to the exothermic agent as in the past is avoided, and the danger of touching the container containing the heating device is prevented.

And a coating material covering the water container and / or the heating agent container. Is folded back at one side of each container body and extends outward from the other contact part, so that when the coating material is pulled, opening of both containers becomes easy and hydration The reaction is also quick and appropriate. Furthermore, since the water container body is made of synthetic resin that shrinks due to heat, when the water container is placed above the exothermic agent container, it shrinks immediately when ripened steam is generated, and the original shape cannot be retained. Thus, the high heat generated by the heated steam can be transmitted appropriately and efficiently.

In addition, the water container and the heating agent container are fixed by the concave and convex portions formed in the water container body and the heating agent container body, so that the water contained in the rain container and the water stored in the rain container are vibrated. Contact with the agent is prevented, and the heating device can be used safely.

Provided with Gil portions 1 1.4 b-is formed, and in the concave portions, partition ribs 1 15 c of a lid 1 15 described later, 1 15 d can be fitted and locked.

The lid body 115 is made of plastic which is integrally molded in the same manner as the container 103, and the outer periphery thereof has a fitting portion fitted in a fitting manner with the fitting portion 103a of the container 103. As well as the formation of 1 15a, it has に abutment surfaces 1 15b and 1 15b that abut against the top surface of each isolation wall 1 1 4— of the container 103 . Thus, in a state where the lid body 115 is covered on the container body 102, the contact surface 1 15 ··· is in contact with the top surface of each of the isolation walls 111-of the container 102. In contact with each other, each of the heating sections 111, 112 and the non-ripening section 113 is a sealed space completely isolated from each other.

Thus, when using the food container 101 formed as described above, after setting the container 103 of the container main body 102, each of the storage containers of the container 1 Put freshly cooked rice A, side dishes B and C in 1, 1, 1 2 and 1 13 respectively, cover the top of the container main body 102 with the lid 115. Then, for example, when eating foods A, B, and C contained in the food container 101 several hours later, the heating device 105 installed inside the food container 101 K is operated. Only the foods A and B in the heating portions 111 and 112 of the foods are ripened.

Next, the heating action of the heating device and the heating vessel will be described. I do.

The opening tape 109 facing the outside of the container body 102 is pulled in the direction of arrow D as shown in FIG. 8 (), and the whole tape is pulled out from the openings 102 e and 106 b. At this time, the closing member 104 fixed to the upper part of the opening 102 e of the container body 102 is bent in the pulling direction along the opening tape 109, but the opening tape is removed. As a result, as shown in FIG. 3 (), the shape is corrected in the direction of arrow E, restored to the outer peripheral surface 102 f side, and covers the opening 102 e again.

By the way, the water bag 107 ruptures when a tensile force is applied to one end, the opening tape 109 is pulled out, and the water bag ruptures from the center of the upper surface 107 a. It comes into contact with the exothermic agent 110 of 108 and permeates almost the entire area. As a result, a hydration reaction is induced, and high-temperature heating steam G is generated by the reaction heat, and is filled in the heat insulating container 105 together with the expanded air. The heated steam G is sent to the inner container 103 through the filter material 106 c, but part of the opening is opened in the insulated container 105 and the opening in the container body 102. Leak outside through 102 e. At this time, when the expanded air and the heated steam G come into contact with the closing member 104 covering the outer peripheral surface 102 f of the opening 102 e, the closing member 104 is caused by a temperature difference between the inside and outside of the container. As shown in FIG. 3 (c), the container is slightly deformed toward the heating device, which is the heat source, and adheres closely to the outer peripheral surface 102f of the container main body 102, closes the opening 102e, and generates high-temperature expanded air. Suppress leakage of heated steam G. On the other hand, the heating steam flows into the heating sections 1 1 1 and 1 1 2 through the water steam discharge holes 1 1 1 b, 1 1 2 b and 1 1 4 a of the container 3 as shown in FIG. As they are sent, foods A and B are heated to high temperatures. That is, the rice A in the first heating unit 1 11 is heated not only from the lower side but also from the upper side, while the side dish B in the second heating unit 1 12 is heated only from the lower side. It is kept at an appropriate temperature. As a result, since the heat vapor is prevented from being dissipated to the outside, the object to be heated, such as food, has a small heat loss and is efficiently heated.

In the heating container 101 of the present embodiment, the case where the opening tape 109 was provided in the heating device 105 and the opening device was pulled out to ripen the heating device 105 was described. The water bag 107 of the heating device 101 is located at the center of the heating agent 110, and is closed at one of the inner surfaces around the opening provided in the container body, which is the envelope 102. The member 104 can be fixed, and if used, a crushing pin can be inserted through the opening to rupture the water bag 107-In this case as well, the danger during use is prevented. Thus, heat loss can be reduced. That is, when the closing member 104 is fixed to the outer peripheral surface of the envelope 102, the closing member 104 is turned up when inserting the pin, and the pin is inserted from the opening where the cover is removed. The water bag 107 of the heating device 105 can be ruptured. On the other hand, if the blocking member 104 is fixed to the peripheral surface, after the pin is inserted into the opening, the blocking member 104 can be pushed up by the tip of the pin. Rupture the water bag to trigger the hydration reaction Can be done. However, in any of the above cases, by removing the pin from the envelope, the opening is covered again by restoring the closing member, so that it is possible to prevent leakage to the outside due to generation of heated steam. .

As described above in detail, according to the above-described heating container, the closing member that deforms toward the heat source is fixed to a part of the periphery of the opening communicating with the inside and outside of the surrounding container, so that the heating device generates low temperature. Steam can be used to close the opening of the envelope. This prevents high-temperature steam from leaking to the outside, which eliminates the risk of burns when touching the envelope and avoids rapid diffusion, so that the object to be heated can be efficiently heated. It is possible to do this. .

In addition, the water bag of the heating device is provided with an opening tape that is pulled out to the outside through the opening of the envelope, and is opened when used. Since the water bag is ruptured by pulling the sealing tape, the outflow of water is ensured, so that the hydration reaction between water and the exothermic agent is appropriate, and the amount of water supplied to the heat agent is small. For this reason, problems such as generation of an abnormally high temperature region and uneven heating can be avoided. Furthermore, since it is only necessary to pull the opening tape for use, it is possible to provide a heating container which is easy to handle.
