Description

Heating Package {FLAMELESS HEATER}

The present invention relates to a heating package that heats food by generating heat using a chemical reaction without fire, and in more detail, puts food in the inside of a bag shape and reacts with a bag and water containing water on both sides. The present invention relates to a heating package that heats food by using heat generated by reacting water and chemicals by attaching a heat-generating chemical to a bag containing water.

In general, in the case of heating food, the food is put in a container and then heated using a burner or the like. The reason for heating food is to eliminate hygiene problems such as contamination of food by germs and the like, furthermore, to taste taste better and to facilitate digestion and absorption nutritionally. In order to heat food, a separate heating tool such as a burner and a heater must be provided. The heating of food by the individual soldiers with such a heating tool during the operation in the army increases the weight of the items that the soldiers must carry. There are many difficulties in performing this. In addition, when eating food that is not heated, starch is aging, and the taste of food is poor, and digestion and absorption are difficult, especially when the temperature and temperature are low. Can be. Also, in the general society, cooking in the mountains is prohibited because of the risk of forest fires, which causes a lot of inconvenience in eating.

In order to solve this problem, various conventionally invented techniques have been proposed. For example, U.S. Patents 4,522,190 and 5,611,329 are proposed, and also in Korean Utility Model 198,025 and 60760. U.S. Patent 4,522,190 puts a chemical bag that generates heat by reacting with water (eg magnesium-based pyroalloy) in a flexible bag in the form of a tea bag and stores the food in a pocket. Place the food you want to heat in your pocket before ingesting it so that water penetrates into the chemical and the water reacts with the chemical to heat the food. U.S. Patent No. 5,611,329 has a heating element bag containing chemicals composed of a plurality of small pockets so that the chemicals are put in each small pocket so that no chemicals are concentrated on one side, preventing more heat from being generated in a particular area. It also makes the heating element bag flexible. In addition, the Korean Utility Model 198,025 attaches a material such as aluminum foil to the heat generating bag on the opposite side to which food is attached so that heat can be transferred in one direction, thereby improving thermal efficiency, and the Korean Utility Model 60,760 is equipped with two water bags. One by one above and below the heating element to explode one water bag to generate heat, and by the heat to burst another water bag so that heat can be continuously generated.

However, in the prior art, when the soldiers during the operation are insufficient in water due to the large volume and the addition of water, there may be a problem, and the food is contaminated or packaged by water vapor generated by water and chemicals. There is a risk that the food is contaminated in the process of peeling the packaging because the packaging is contaminated, there is a fear that the heat is not applied sufficiently on the other side because there is a heating bag on one side.

In addition, when the bag is filled with water to react with the chemicals to induce a reaction by popping the bag, there is a fear that the heat does not continue to continue because the water remains in the bag may not react all, such problems In order to solve the problem, it can be used to allow the water to be discharged out of the bag and reduce the risk of water overflow. However, in this method, food is biased downward by gravity, and the thickness of the lower portion is formed to be thicker, so that the lower portion of the food may not be sufficiently heated.

Therefore, an object of the present invention was created to solve the problems of the prior art, to form a pocket-shaped heating bag is provided on both sides of the material to be heated to heat the contents on both sides so that it can be heated well It is in the form of a pocket, so that the heat package and the contents are in close contact with each other to increase the heat transfer rate, and the heat generated takes the form of indirect heating by conduction. It is to provide a heating package that allows the heating material to chemically react as a whole to allow the contents to be heated evenly and to allow the heating time to last.

In order to achieve the object of the present invention, the heating package according to the present invention is formed of a packaging material for passing the liquid and air and a heating bag having a heating element for generating heat by reacting with the liquid; A liquid bag having a liquid for supplying the heating bag; A tear strap that is adhered to the surface of the liquid bag to allow the liquid in the liquid bag to be discharged; And a first heating bag formed of a heat-resistant and waterproof packaging material including a vapor discharge hole for discharging water vapor generated by heat generated by a reaction between the heating element and the liquid and exposing the cutting string to the outside.

The present invention will be more clearly understood from the following description, in comparison with the prior art, with reference to the accompanying drawings.

1 is an exploded perspective view of a heating package according to the present invention. 2 is a cross-sectional view of a first heating bag according to the present invention. Referring to FIGS. 1 and 2, the heating package 100 includes two inner wrappers 10 ′ and an outer wrapper 10 overlapping each other, as shown in FIG. The first heating bag 20 and the second heating bag 20 'are produced. And the part formed between the 1st heating bag 20 and the 2nd heating bag 20 'is formed by the handle part 30. As shown in FIG. The two pieces of wrapping paper are formed on the outside and inside of each of the heating packages 100. The length of the handle portion 30 of the wrapping paper formed on the outside is longer than the handle portion 30 of the inner wrapping paper 10 '. , The inner wrapper 10 'can reach the A-A' line of the handle portion 30 and the outer wrapper is longer than the AA 'line. Therefore, when cutting the upper portion of A-A 'of the handle portion 30, the outer wrapper 10 is torn, and the inner wrapper 10' is different from each other in the line A-A 'unlike the outer wrapper 10. It is configured to be connected. Accordingly, the handle portion 30 in the line A-A 'allows the hole 40 to be formed. It is attached between the first heating bag 20 and the second heating bag 20 'and serves as a boundary plate of the first heating bag 20 and the second heating bag 20'. The outer edges of the inner wrapper 10 ′ and the outer wrapper 10 overlap and seal each other to form an inner space such that the first heating bag 20 of the heating package 100 is generated as shown in FIG. 2 to generate heat. The bag, the liquid bag, the tear string 50 and the paper tissue enter the interior of the first heating bag. In addition, as shown in FIG. 2, a second heating bag 20 ′ is formed.

3 is a cross-sectional view of B-B 'showing an embodiment of a heating package according to the present invention. As shown in FIG. 3, the heating bag 21, the liquid bag 25, and the paper tissue 29 are formed, and the tear string 50 is a means for popping the liquid bag 25 on the surface of the liquid bag 25. ) Is attached so that the liquid bag 25 can burst when the tear string 50 is pulled out. The tear string 50 is configured to be attached to the surfaces of the two liquid sacs 25 through holes formed in A-A '.

The heating bag 21 is a solid-state heating element is built-in, the heating bag 21 is manufactured to be flexible to have a storage or mobile advantage, and can use a natural fiber non-woven fabric, natural pulp non-woven fabric or foamed resin sheet, etc. As shown in FIGS. 1 to 3, the heating elements of the heating element are generated in a plurality of cells so as to generate the same heat within a predetermined area without being biased to one side. Therefore, when the liquid and the heating element of the heating bag 21 is not divided in the form of a cell when the heating element can be biased to one side in the heating bag 21 is not able to heat the entire contents to be heated It is divided into cells so that they can be heated by cell unit.

Solid phase heating elements are composed of magnesium (Mg): 75 to 94%, iron (Fe): 5 to 15%, and sea sand (sea sand): 1% to 20%. The reason for adding seaweed is that the seaweed can hold the heat generated by the chemical reaction of the heating element and the exothermic solution, thus maintaining the exothermic temperature and increasing the exothermic time. And the solid-state heating element is to put the magnesium and iron in the ball milling machine in the ratio shown above, and to perform the milling operation and at the same time to mix with each other, so that it can be used to put the maritime in the above ratio.

The liquid bag 25 is a means for storing a substance that generates a reaction heat by causing a chemical reaction with the heating element of the heating bag 21, and contains 0.5 to 20% aqueous NaCl solution. The reason why the liquid is composed of NaCl aqueous solution is that the electrolyte composed of water and NaCl promotes the reaction between the heating element and the water in the heating bag 21 so that the exothermic reaction occurs better, and the liquid may freeze in winter. To prevent this, use a NaCl aqueous solution to lower the freezing point of the liquid so that it can be used in winter. In addition, when there is no fear of freezing the liquid, instead of adding NaCl to the liquid, the salt can be put into the heating element of the heating bag 21 to be used. In addition to NaCl, MgCl, CaCl, KCl and the like can be used.

In order for the heating bag 21 to react with the liquid, the liquid bag 25 is exploded so that the liquid substance is discharged to penetrate into the heating bag 21 to cause a chemical reaction. To this end, by attaching the cutting string 50 to the outer surface of the liquid bag 25 and pulling the cutting string 50, the liquid bag 25 is torn, so that the liquid substance is discharged.

Then, the liquid substance is out of the liquid bag 25 and reacts with the heating element so that the amount of liquid that the liquid boils over the reaction is insufficient, the reaction does not occur sufficiently. In order to prevent this, a paper tissue 29 is provided between the liquid bag 25 and the heating element bag 21 to prevent the liquid from overflowing by storing the predetermined amount of the liquid discharged from the liquid bag 25 and further, Is storing the liquid, so that the liquid is put into the heating element at once and prevents the heating element from reacting at a time, so that the heat generation can be continued evenly, and the tissue acts as a wick to absorb the liquid and supply the liquid to the heating element bag as a whole. To react. The tissue is preferably configured to have the same size as the heat generating bag 21.

The wrapping paper wraps the liquid bag 25, the heating bag 21, and the paper tissue 29 so as to form a bag, and one side of the wrapping paper is formed longer than the other side so that the long portion is formed by the handle of the heating package 100. It is formed as part 30.

The handle portion 30 is formed in the same shape in the first heating bag 20 and the second heating bag 20 'and the heating package 100 according to the present invention will be used to combine the handle portion 30 A tear string 50 which allows the liquid bag 25 of the first heating bag 20 and the liquid bag 25 of the second heating bag 20 'to burst can be exposed out through the handle portion 30. Make sure Therefore, by cutting the constant portion of the handle portion 30 so that the cutting string 50 is exposed to be heated to pull the cutting string 50 to heat, and also, the handle portion 30 is a heating element It is used as a passage for allowing the steam generated by the reaction heat of the liquid to be discharged.

The cutting string 50 is a means for discharging the liquid by causing the liquid bag 25 of the heating package 100 to burst, and both ends of the one strap are connected to the liquid bag 25 and the second bag of the first heating bag 20. Attached to the surface of the liquid bag 25 of the heating bag (20 ') and cut a certain portion of the handle portion 30 to expose the cut string 50 to the outside to pull the cut string 50 By pulling the string 30, the surface of the liquid bag 25 is torn to allow the liquid to be discharged.

Referring to FIG. 4, the heating package 100 according to the present invention seals the outer edges of the remaining sides except for one side in a state where the first heating bag 20 and the second heating bag 20 ′ overlap. The outer edge in the opposite direction to the side in which the handle portion 30 is formed is formed so that the heating package 100 is formed in a pocket shape. Therefore, the contents can be inserted into the heating package 100 through the unsealed portion so as to be heated. The heating package 100 is formed in a pocket shape so that the contents to be heated are in close contact with the heating package 100 so that heat transfer can be well performed. In addition, water vapor generated in a chemical reaction by a solid heating element and a liquid directly comes into contact with food in the case of existing third-party products, which may be detrimental to food safety. Indirect heating is adopted to prevent water vapor from reaching the contents. The wrapping paper of the heating package 100 has waterproof, heat resistance, and impact resistance. In the line A-A ', the inner wrapper of the first heating bag 20 and the inner wrapper 10' of the second heating bag 20 'are configured to be connected to each other to form one component.
