Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a heating vessel. More specifically, the present invention utilizes a reaction between a non-flame-burning type chemical exothermic agent and water, and a heating container that can cook food in a similar state, regardless of use under any circumstances. About.
[0002]
[Prior art]
The term “non-flame-burning type chemical exothermic agent” used in the present invention is different from fossil fuels and animal and plant fuels which react with oxygen to produce a flame and burn, and generate heat, for example, by an exothermic reaction such as hydrogenation reaction. Defined as a compound or composition. In the following description, the “non-flame burning type chemical exothermic agent” may be simply abbreviated as an exothermic agent.
[0003]
As such a heating agent, various proposals have been conventionally made, such as quicklime (CaO), powdered magnesium, a composition composed of iron powder, activated carbon and salt, a powdered magnesium, a composition composed of powdered lime and powdered aluminum. Have been.
[0004]
One of the important uses of the exothermic agent is to heat cooked food and the like anywhere, for example, in a station valve. When heating cooked foods using a heating agent, it is important to use the amount of water that reacts with the heating agent based on the stoichiometry, and to open it from the viewpoint of food hygiene. The purpose of the present invention is to make the exothermic agent react with water without using it, and to reduce the cost by making the exothermic agent a disposable consumable so as not to have a complicated mechanism but to make sure that the exothermic agent reacts with water in as simple a manner as possible. Hereinafter, the prior art will be examined from these three points.
[0005]
Each of the exothermic agents reacts with a stoichiometric amount of water to generate a predetermined amount of heat. The reaction mechanism will be described using quick lime (CaO) as an example. CaO reacts with H ₂ O according to the following reaction formula to generate 15.2 Kcal of heat.
CaO + H ₂ O = Ca (OH) ₂ + 15.2Kcal
The molecular weight of CaO is 56.08. On the other hand, the molecular weight of H ₂ O is 18. That is, to generate 15.2 Kcal of heat, 18 grams of H ₂ O must react with 56.08 grams of CaO. For 56.08 grams of CaO, if H ₂ O is 18 grams or less, unreacted CaO remains, while if H ₂ O is 18 grams or more, surplus water remains after the reaction is completed. Burden. This thermodynamic theory applies equally to the reaction of water with exothermic agents other than quicklime (CaO).
[0006]
In the case of a heating agent composed of two or more components, for example, a heating agent composed of powdered aluminum and powdered calcium oxide, in the first stage reaction, the powdered oxidation calcium reacts with water to form calcium hydroxide. It is produced and undergoes a sequential reaction in which powder aluminum and calcium hydroxide cause a further reaction in the second stage reaction. Also in the case of this sequential reaction, the use of the accurately weighed water in the first-stage reaction causes the subsequent sequential reaction to be properly performed, and thus the above-described thermodynamic theory is applied.
[0007]
From the above description, it will be understood that in the case of heating a food or the like utilizing the reaction between the exothermic agent and water, it is important to react with water weighed as accurately as possible based on the stoichiometric amount. . As a means for solving this problem, it has been conventionally proposed to use a plastic water bag filled with an amount of water necessary for reacting with a predetermined amount of exothermic agent, and has produced corresponding results.
[0008]
Furthermore, when heating a prepared food or the like using a heating agent, it is important to pay attention to food hygiene. In recent years, examples of heating foods using exothermic agents include traditional station valves, meals in private rooms at hotels and inns that dislike flame-burning fuel, home delivery to sick rooms and nursing homes, outdoor sports, etc. In addition, more and more local governments have stockpiled them in case of an emergency disaster in which the heating means such as gas and electricity is shut off.
[0009]
In any case, the exothermic agent should be used in an environment where there is an unspecified number of various people, or in the field, or in an environment where complex elements are mixed, compared to general households where the environmental situation is almost fixed There are many. In such an environment, it is desirable to heat the container without opening it so as not to be contaminated.
[0010]
As means for solving this, for example, Japanese Patent No. 2719097, Japanese Patent Application Laid-Open No. H11-292155, and Japanese Patent Application No. 2002-173902 generally disclose a heating container capable of containing a heating agent and water, and a heating container. In a heating container comprising a food container which is placed in a state where the heat generating container is hermetically sealed and can store food, and a lid attached to the food container, a predetermined amount of the heat generating agent is permeable bag. The exothermic agent bag enclosed in the bag and the water bag filled with water were connected by a drawstring that simultaneously cleaves, the two bags were stacked and housed in a container, and the drawstring was perforated on the wall surface of the heat-generating container. Disclosed is a heating container structured to be pulled out from a drawstring pullout hole.
[0011]
This prior art is desirable from the viewpoint of food hygiene because the exothermic agent and water can react without bringing the food into contact with the outside air while the container is sealed. However, the structure of the heat-generating container for reacting the heat-generating agent with water is too complicated and sophisticated, and a certain amount of knack is required to pull out the pulling string. In some cases, there is a drawback that the reaction between the exothermic agent and water is not completed because the reaction may be interrupted before the drawing is completely completed. Further, there is a disadvantage that the mechanism is complicated and the manufacturing cost is high.
[0012]
By the way, the manufacturing cost of the heat generating container of this prior art is about 10 times or more than the manufacturing cost of manufacturing the station valve container by a vacuum forming method using a highly versatile expanded polystyrene as a material for the station valve container. There may be cases where cost performance does not match at all.
[0013]
[Problems to be solved by the invention]
The problem to be solved by the invention is a heating container that heats food by utilizing the reaction between a non-flame-burning type chemical heating agent and water. On the other hand, water that is accurately weighed based on the stoichiometric amount is added to the non-flame-burning type chemical exothermic agent and reacted, and the food is cooked in the same condition no matter what the condition. It is an object of the present invention to provide a heating vessel having a very simple structure.
