Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to foods and drinks, for example? Relating to a heating container with an integrated structure in which food such as coffee, tea, curry roux, soup, stew, milk drinks, juice, etc., and a heating attachment for simply heating the food are separated and sealed. . More specifically, the present invention relates to a rupture rod for a heating device for causing the heating device to generate heat from outside the heating container.

<Prior art> Foods and drinks, such as alcoholic beverages, coffee, tea, curry roux, soups, stews, milk drinks, juices, etc., are integrated into an integrated structure with a heating device that easily heats them. Means for heating by heating devices are known.

Such an integrated heating device is suitable for use with pyrogens such as Ca.
The reaction between O+CaC and inducing substances such as water-containing antifreeze is based on the water utilization reaction. The inducing substance and the pyrogen are usually arranged in a non-contact manner, for example, in a compartment where the inducing substance is sealed. Therefore, a relatively long rupture rod is required to allow the inducing substance in the compartment to flow out from outside the heating container.

<Problems to be Solved by the Invention> However, such a bursting rod for a heating device is in the shape of a toothpick. Even if a rupture rod with such a shape is inserted into a compartment containing an inducing substance, for example, the size of the rupture rod corresponds to the outside diameter of the rupture rod, that is, the opening between the rupture rod inserted into the chamber and the wall of the compartment. There is no gap between the hole and the hole, and the edge of the partition wall is in close contact with the outer circumferential surface of the rupture rod. Therefore, the triggering substance in the compartment does not flow out smoothly, and therefore, it is necessary to insert the bursting rod into the compartment and then pull it out one by one. If the rupture rod is not removed, it is easy for the eater to misunderstand that the heating device has started, and even after 1 lapse of 1 time, the eater will not be able to start a good heating operation. A friend that has already deteriorated for some reason, a friend with a defect that makes it a so-called defective product. Friend, this is very troublesome.

In the present invention, at the start of the heating operation of the heating device, the rupture rod is inserted into the chamber containing the inducing substance and ruptured, and the rupture rod is not removed each time, but the rupture rod is left as it is to prevent the inducing substance from flowing out. To provide a bursting rod for a heating device which can perform well and quickly and reliably generate heat.

Another object of the present invention is to provide a bursting rod for a warming device, which allows the heat generating operation to be performed satisfactorily by simply inserting the bursting rod into the chamber containing the triggering substance.

In order to solve the above-mentioned problems, the present invention provides a heating container containing food and drink and having a sealed insertion hole. A heating device g1 is integrally installed in a compartment separated from the food and drink, and the heating device is sealed in a compartment and consists of a mind-inducing substance and a pyrogenic substance, and is inserted through the sealed insertion hole to rupture the compartment. The rupture rod has a sharp tip and has a triggering substance outflow guide, and this tAC discharge guide has a triggering substance containing compartment and a sealed insertion hole. ,>W□and! , ≧W2.

As described above, by configuring the outflow guide, the inducing substance containing compartment, and the sealing insertion hole in the relationship l□〉W□ and Z, =W, the sharp part of the bursting rod can break through the sealing material. , through the sealing hole, and further into the compartment.

The triggering substance is then forced to flow out of the compartment along the outflow guide. Therefore, even without taking out any bursting rods, it is possible to contact the exothermic substance and at least cause a water utilization reaction.

The bottomed cylindrical body provided in the heating container to partition and accommodate the food and drink and the heating device is molded from a material with good heat resistance, pressure resistance, and thermal conductivity.

Examples of such materials include metals such as iron, aluminum, steel, stainless steel, etc., which have been subjected to corrosion treatment, and heat-resistant polymers. In addition, the compartment formed by the above-mentioned compartments and used to seal the material in the reaction chamber may be made of, for example, a heat-resistant polymer, a non-heat-resistant polymer, M
If a metal laminate material made of lg, cloth, gold sWi, and gold is preferred, a bag-shaped material made of high molecular weight polymer may be used. When the compartment is formed from such a suitable material, unlike the case of water bags made of polymers, which have not been commonly used in the past, there is a possibility that the cells may be induced by the passage of time (during long-term storage). It is unlikely that water molecules in the material will permeate through the material, and the material can completely retain water. Therefore, it is possible to avoid the disadvantage that the pyrogenic substance is accommodated in the reaction chamber without contacting the triggering substance and is degraded by reacting with the moisture before use. Therefore, it is possible to avoid the important disadvantage that the exothermic operation does not take place despite the hydration reaction between the pyrogen and the triggering substance during the exothermic operation. The triggering substances used are water and antifreeze solutions. As the antifreeze solution, an aqueous salt solution, an aqueous water-soluble alcohol solution, or a mixture thereof is used.

The aqueous salt solution may be a water-soluble salt of a water-soluble group, that is, a mono- to trivalent metal, or an ammonium water bath solution, such as sodium, potassium, magnesium, calcium, barium, copper, iron. , mono- to trivalent metals such as nickel, zinc or aluminum, halogen atoms, carbonate radicals,
Examples include water-soluble salts with sulfate roots. Further examples of suitable water-soluble salts include NFLCI s CaCJg % K

Examples include water-soluble inorganic salts such as 1[, ), SO, and these 'ff:1. i! An aqueous solution containing the above is used.

Water-soluble organic acid salts thereof, such as the sodium and potassium salts of citric acid and tartaric acid, can also be used. Furthermore, like seawater 2
Even an aqueous solution containing 4 or more salts is fine.
The concentration of the aqueous salt solution may be 0.5% or more, and may be adjusted to the concentration of a saturated solution for guests with a difference of B, preferably 1 to 15 degrees S. (9) As the water-soluble alcohol aqueous solution, it is inexpensive and convenient to use a commercially available aqueous solution of antifreeze containing polyethylene glycol. Examples of water-based alcohols include water-soluble polyhydric alcohols, such as ethylene glycol, glycerin, and polyethylene glycol, as well as mixtures thereof, as well as other ethylene glycol derivatives that do not freeze even when cooled in an aqueous solution state. Any material can be used as long as it is not easily indicated.

As the exothermic substance to be accommodated in the reaction chamber without contacting the inducing substance, any substance that generates heat in the water utilization reaction such as CaO% CIL (J2) can be used.

It is convenient to make the exothermic substance into granules by combustion, and if necessary, use a water-free solvent and make it into granules with a neutral or alkaline water-soluble binder to prevent scattering. It is desirable to apply a similar processing A.
o Furthermore, it can be calculated from the use of pyrogens, the specific heat of the food and drink to be heated, and the amount of heat from the water use reaction.

For example, to raise the temperature of drinks such as alcoholic beverages, coffee, and tea by 50°C or more as a liquid with a specific heat of 1, % Ca is required.
If the water content in the aqueous salt solution is about 40-459 or more, the water content in the water-soluble alcohol aqueous solution should be about 12-13II or more. Furthermore, heat-resistant granules that do not participate in the water utilization reaction between the above-mentioned pyrogen and inducing substance may be dispersed and arranged in the layered structure. This granular material serves as a diluent/insulating material and as a clogging prevention function, and it is important to mix it into the exothermic substance and to provide the granular material in the reaction chamber. Examples of such heat-resistant granules include sand, pebbles, slag, and glass. By providing this granular material, it is possible to avoid pyrogenic substances such as CaO in handling hazardous materials, and to absorb the heat generated during heat generation. This is to maintain the effect. Furthermore, the granules are
In addition to absorbing the heat generated by the water utilization reaction, it also acts as a so-called safety valve to prevent abnormal pressure rises, thereby increasing safety. In particular, this heat-resistant granular material is located on the inner lid side of the reaction chamber and is structured in a layered manner, thereby achieving not only the above-mentioned heat retention but also good ventilation of the water vapor generated by the reaction. It is something.

The inner lid placed at the opening of the reaction chamber is made of a material that transmits high-temperature water vapor generated during the hydration reaction. Examples include paper, metal foil, metal laminate material, cloth, etc., and the thickness is not particularly limited, but 0.01 m
If the material is made of paper, metal foil, or metal laminate material, holes of any shape such as circular, rectangular, or other shapes that do not allow the fine powder of the exothermic substance to pass through, but allow water vapor to pass through, are preferably used. The water permeability is improved by opening it or making a "+"-shaped notch. If the inner lid is formed of wire mesh, lath mesh, punched plate, etc. as necessary, the above-mentioned processing can be omitted.

By disposing a breathable material between the inner lid and the bottom lid, the inner lid and the bottom lid are prevented from coming into close contact with each other.

Therefore, steam can be effectively discharged without being hindered.

Examples of the breathable material include fibrous materials, nonwoven fabrics, sponges, cotton, and similar materials.

The bottom cover has a hole in the center for heat generation. The hole is normally sealed with a sealing material such as paper, metal foil, metal bilaminate, meltable polymer, wax, or the like. In particular, if the sealant is a meltable polymer (PET) that melts at 80 to 85°C, it is preferable to apply the sealant to the inner or outer side of the bottom cover. By applying the sealant to the surface of the sealant, even if there is an accident and the temperature rises inside the reaction chamber, the sealant will be forcibly melted by the high temperature steam. Therefore, the sealing hole is automatically opened and the high temperature water vapor is released to the outside, so it is safe. Furthermore, in order to allow steam to be discharged more smoothly, a plurality of small holes may be provided in the bottom cover and sealed in the same manner.

Furthermore, the rupture line that allows the inducing substance to flow out from the compartment from outside the bottom cover through the sealing hole is formed of, for example, metal, synthetic resin, or similar materials. The rupture line may be formed into any shape, such as a columnar shape, a flattened shape, or the like. Because the rupture wire is forcibly inserted into the reaction chamber from outside the bottom cover due to heat generation, the insertion tip side is formed into a sharp, conical shape, for example, and the entire length is protected from heat-generating substances. It is preferable to form it in a flat shape that receives as little resistance as possible. Further, an outflow guide is formed at the rupture line to allow the triggering substance within the compartment to flow out of the compartment. The outflow guide may be, for example, in the form of a through groove passing through the center of the rupture line along the axial direction, or in the form of a concave groove formed by cutting a concave shape in the center of the rupture line along the axial direction. When the rupture line has a flat shape, the position where the hotl exit guide is formed can be arbitrarily selected, even if it is in the form of a groove formed by cutting a concave shape in the axial direction on the side of the rupture line. One or more outflow guides are formed for the rupture line. The outflow guide may be formed in the form of a telescope having a plurality of branch paths, so that the triggering substance to be outflowed is guided out from the rupture line in multiple directions. As described above, the shape may be shifted by h as long as the structure allows the inducing substance in the compartment to flow out well with the rupture line inserted into the compartment. The above-mentioned outflow guide, the inducing substance containing compartment, and the sealing insertion hole are constructed in the following relationship. That is, the total length of the outflow guide in the axial direction is greater than the inducing substance containment space (the total height of the inducing substance-sealing chamber). Please note that the diameter of the rupture line is equal to or larger than the diameter of the sealing insertion hole. When the sharp part of the rupture line is first inserted into the sealed insertion hole and then advanced into the compartment of the inducing substance, the interior of the compartment and the exterior of the compartment are communicated via the outflow guide. Therefore, even if the rupture line remains inserted into the compartment, the triggering substance can be effectively drained from the compartment. Due to the efflux of triggering substances, the water use response is immediately initiated,
The heat generating operation can be realized quickly and reliably. The bottom lid of the heating container is seamed to the container body using a seaming machine in the usual manner. In order to improve the sealing performance of this seamed part, coating treatment is preferably performed using a water-repellent polymer solution. The sealed portion formed by this coating completely prevents absorption of moisture in the outside air from the seamed portion into the reaction chamber. Therefore, deterioration of the pyrogenic substance is prevented over a long period of time (during storage).

<Example> Specific examples of the present invention will be described below, but the present invention is not limited thereto. Structure of h0 heating container In FIG. 1, reference numeral 1 indicates a heating container. The heating section 51 is included in the container body 2t. The container body 2 is preferably molded from a heat insulating material. A fully open type or pull-top type upper lid 3 is provided at the upper end of the container body l. A bottomed cylindrical body 4 is disposed at the bottom of the container body 2.

The cylindrical body 4 forms a food/drink storage chamber 5 and a reaction chamber 6 within the container body 2. Inside the reaction chamber 6, a pyrogen (including some dilution and heat insulating material) 7 is accommodated at its inner bottom.

A bottom cover 12 is disposed on the lower side as indicated by h in the drawing of 1, and its peripheral edge 13 is integrally seamed using a normal seaming machine (not shown).

The seamed portion 14 is coated with a polymer solution and sealed. This sealing portion 15 prevents water molecules in the outside air from entering the reaction tube 6 from the seaming portion 14 . A sealing insertion hole 16 is opened in the center of the bottom cover 12. The sealed insertion hole 16 is at the bottom! 12 is normally sealed from the outer surface side with a sealing material 17. A similar sealing material 17 may be provided on the inner surface of the bottom cover 12. Instead of the sealant 17, a meltable sealant is applied to either the inner or outer surface of the bottom cover 12 to form the small holes 20,
The insertion sealing hole 16t can also be sealed. The small holes 20 allow water vapor generated by the hydration reaction to be more smoothly discharged to the outside of the heating section.

In addition, in the figure, reference numeral 21 denotes a cover lid that is removably mounted on the bottom lid 12. The cover lid 21 is attached as shown in FIG. 1 during the heat generation operation, and the high temperature water vapor generated during the water utilization reaction escapes to the outside of the heating section. The configuration of the rupture rod 18 will be explained below.

Structure of Bursting Rod The rupturing rod 18 has a flat cross section, as shown in FIGS. 2 and 3, for example. The tip of the bursting rod 18 is formed into a sharp portion 19 . A knob piece 23 is integrally provided on the rupture rod main body 22 on the opposite side to the sharp portion 19. A trigger substance outflow guide 24 is formed in the center of the rupture rod body 22 along the axial direction. The outflow guide 24 is made of, for example, a concave cut groove, as shown in the third column. The cut groove is selected to have any shape, such as a U-shape, a V-shape, or the like. The outflow guide 24tf may be formed on the upper and lower surfaces of the rupture rod body 22, as shown in FIG. Fourth
In the case of the figure, the outflow guides 24 are formed facing each other, but the formation positions thereof may be slightly shifted in the horizontal direction. Furthermore, as shown in FIG. 5, the outflow guide 24 may be formed by penetrating the rupture rod body 22.
Furthermore, as shown in FIGS. 6 and 7, an outflow guide 24 may be formed on the side of the rupture rod body 22. In FIG. 6, the upper end of the outflow guide 24 has a sharp portion 19.
It is facing the oblique edge of. Further, as shown in FIGS. 8 and 9, the root portion of the rupture rod body 22 may be formed into a constricted portion 25. In the case of the rupture rod 18 having this constricted portion 25, it is effective when the cross section is cylindrical. That is, when the rupture rod 18t is inserted into the seal insertion hole 16 and positioned between the constricted portion 25t and the seal insertion hole 16, a gap is formed between them. Therefore, the water vapor generated by the water utilization reaction can be smoothly released to the outside of the heating section.

The rupture rod 18 shown in FIGS. 10 and 12 has a cylindrical cross section. In the case of the rupture rod main body 22 shown in FIG. 10, an outflow guide 24 consisting of a concave groove is formed along the axial direction at one point on the curved surface. In the case of the broken bar body 22 shown in FIG. 1, outflow guides 24, 24 consisting of grooves are formed at nine positions corresponding to each other on the curved surfaces thereof. Furthermore, the bursting rod body 22 shown in FIG.
In this case, the outflow guide 24 is formed to pass through the rupture rod body 22. The diameter of the rupture rod 18 formed as described above! , and the length 11 of the outflow guide 24, the total height W1 of the inducing substance containing compartment 9, and the diameter W8 of the sealed manhole 16,

Effect> In order to cause the secondary pyrogenic substance 7 and the inducing substance 8 to undergo a water-use reaction while being accommodated in the heating chamber in a non-contact state, the sealing material 17 is inserted into the bursting rod 1.
Break it through with the sharp part 19 of No. 8 and let it enter as it is. Further, the sharp portion 19 is caused to enter the compartment 9 (see the dotted line state in the fa1 diagram). Then, the inducing substance 8 flows through the outflow guide 24.
The rupture rod 18 is allowed to flow out of the compartment 9 and comes into contact with the exothermic substance 7 to cause a water utilization reaction without removing the rupture rod 18. Cover lid 21 on bottom 1i11
2 Cover it on top. By carrying out the aqueous phase reaction within the reaction chamber 6, high-temperature water vapor is generated, and the temperature within the reaction chamber is gradually increased. A portion of the water vapor is released from the sealing hole 16 to the outside of the container, and is restricted so that the inside of the reaction chamber 6 does not become under abnormal pressure. The temperature inside the reaction chamber 6 is exchanged with the food and drink through the cylinder 4t. In a more preferred embodiment, when the water vapor is released to the outside, the water vapor flow path is not clogged and is released very effectively. In other words, some parts of the soil become muddy due to water use reactions.
, is prevented from further flowing out at the particulate matter layer 10, and almost never reaches the inner lid 11. Therefore, the water vapor outflow path is not clogged, and the water vapor flows smoothly out of the container. It will be released.

As explained above, according to the present invention, the bursting rod is inserted into the inducing substance-containing compartment and ruptured without removing the bursting rod in order to start the heat generation operation. ,
Allowing the triggering substances to flow out well in the same state,
The exothermic action is achieved quickly and reliably, and the operation is as simple as inserting the rupture rod into the chamber containing the triggering substance, so there is no need for the conventional operation of inserting and removing it. For the user, a heating device that is easy to use is obtained.

In addition, in the embodiment of the present invention, the case where the container body 2 and the cylinder body 4 are molded separately has been illustrated and explained, but if necessary, the container body 2 and the cylinder body 4 may be integrally molded. ,
It can also be combined with various members as in the above embodiments.
Of course it is possible.
