Embodiment 1 of the present invention will be described below with reference to the drawings.
FIG. 1 is a cross-sectional view showing a use state during heating according to the present invention, FIG. 2 is a perspective view showing the use state, and FIG. 3 is a perspective view of components of the present invention. As shown in FIG. 3, the portable simple heater A of Example 1 is a hydrous exothermic agent contained in a bag-like main body 1 having a size capable of storing an object to be heated and a substantially flat water-permeable bag 2a. 2 and three members of a water bag 3 a containing water 3.

  The main body 1 is provided with a bag 4 made of a heat-resistant aluminum-containing material with a gusset 4a on the bottom surface that is large enough to accommodate an object to be heated. The bag 4 is flat when the gusset 4a on the bottom surface is folded. It becomes a sheet. In a state in which the bag 4 is flattened, a cross-sectional corrugated paper sheet 5 is stuck to the outer periphery of the bag 4. This paper sheet 5 is for heat insulation or heat insulation, has a certain thickness and strength, and has flexibility, except for the gusset 4a on the bottom surface of the bag 4 and the upper end side portion thereof. The outer peripheral surface is covered.

  The hydrous exothermic agent 2 contained in the substantially flat water-permeable bag 2a is a mixture of powdered quicklime (CaO) and powdered aluminum (Al) in a ratio of 1-2: 1 to 2 per total weight. Is formed. Here, a heat generating agent manufactured by Kyodo Co., Ltd. is used (see Japanese Patent Application Laid-Open No. 2003-342558). The exothermic agent is temperature controlled and time controlled so that a temperature of about 90 ° C. to 100 ° C. can be maintained for at least 20 minutes. Moreover, the bag 2a which puts these powder quicklime and powder aluminum uses the water-permeable thing.

  Furthermore, the water bag 3a containing the water 3 is heated to generate calcium aluminate by reacting with the powdered lime in the hydrous exothermic agent 2. Here, water in a water bag manufactured by Ebara Corporation is used as catalyst water, but this water may be tap water, pond water, river water, rain water, etc., other than salt water. The amount of water used may be three times or less the weight of the heat generating agent, but an amount equivalent to twice the amount is appropriate.

  Next, how to use the portable simple heater A will be described. First, a main body 1 folded flat, a hydrous exothermic agent 2 contained in a flat bag 2a, and a water bag 3a containing an amount of water 3 corresponding to the hydrous exothermic agent 2 are prepared as one set. To do.

  And the main body 1 is taken out from this, the paper sheet 5 of the outer periphery of this main body 1 is rounded, the gusset 4a of the bottom face of the bag 4 inside is expanded, the main body 1 is made into a substantially cylindrical shape, FIG.1 and FIG.2. Stand on a flat surface as shown in. Thereafter, the bag 2a containing the hydrolytic exothermic agent 2 is placed on the bottom surface inside the main body 1 from the upper opening of the bag 4 of the main body 1, and the bag 2a of the hydrous exothermic agent 2 is similarly placed. A bottle 6 of soft drink, which is an object to be heated, is placed on the top. Then, the water bag 3a is broken and water 3 is put into the main body 1 to heat the hydrolytic exothermic agent 2 and warm the bottle 6. At this time, the upper opening of the bag 4 of the main body 1 may be left open, and the opening is a clip or the like (not shown) or a fitting type provided in advance in the opening of the bag 4 as shown in FIG. The opening / closing seal 4b may be closed.

  The water 3 contained in the bag 4 of the main body 1 reacts with the powder quicklime in the hydrous exothermic agent 2 and the water 3 to generate a first exothermic reaction, thereby generating calcium aluminate. Calcium aluminate reacts with powdered aluminum in the hydrous exothermic agent 2 to cause a second exothermic reaction, the hydrous exothermic agent 2 generates heat, and the bag 4 of the main body 1 is filled with water vapor. The bottle 6 of the soft drink is heated.

  When the soft drink bottle 6 has a capacity of 350 ml, it rises to 65 ° C. to 72 ° C. in 5 to 6 minutes and can be heated for about 15 minutes. At this time, since the paper sheet 5 is coated on the outer periphery of the main body 1, the paper sheet 5 has a heat retaining effect inside the bag 4 and is efficiently heated. The sheet 5 has a heat insulating effect on the outside, and even if the paper sheet 5 is touched by hand, it is not heated to the left, and there is no risk of burns, which is safe.

  Since the exothermic agent 2 after use is a compound product of powdered aluminum and quicklime, it can be used as a soil improver, and it has been confirmed that acidic soil is changed to alkaline soil. Further, the hydrous exothermic agent 2 is odorless when generating heat, generates a small amount of hydrogen gas, but is harmless to the human body.

  FIG. 5 shows a sectional view of Example 2 of the present invention when heated. As shown in FIG. 5, the portable simple heater B of Example 2 is obtained by dividing the bag 4 of the main body 1 into a main bag 7 and a subbag 8, and these main bag 7 and subbag 8. And the paper sheet 5 is wound around and adhered to the outer periphery of these. And the bottle 6 of the soft drink which is a to-be-heated object is put in the main bag 7, the bag 2a and the water 3 of the said hydrous heat generating agent 2 are put in the subbag 8, and the upper opening part of the said subbag 8 is closed. As a result, the hydrolytic exothermic agent 2 reacts with water, and the inside of the auxiliary bag 8 is filled with water vapor in the same manner as in the first embodiment, and the bottle 6 in the main bag 7 adjacent to the auxiliary bag 8 is also heated. It is done. In addition, the main bag 7 and the sub bag 8 may be bonded together, or a pocket (not shown) may be provided outside or inside the main bag, and this pocket may be used as the sub bag. The main bag 7 is a heat-resistant bag with a gusset 7a on the bottom as in the case of the bag 4.

  In the description of FIG. 5 above, the main bag 7 is configured such that the soft drink bottle 6 to be heated is put into the main bag 7 and the heated object is heated, but in the case of Example 2, the main bag is used. It is also possible to warm water by putting water or other object to be heated directly into 7, and after heating, these objects to be heated can be taken out from the main bag 7 and used. In addition, in the sale of liquor, etc., if the cup containing liquor and the portable heater B are sold as a set, the buyer puts the cup into the main bag 7 and the hydrolytic heat generated in the bag 2a. If the agent 2 and the water 3 are put in the auxiliary bag 8, a hot soup can be drunk on the spot and it is very convenient.

  If these portable simple heaters A and B are used, they can be used in urban disasters where the use of open flames is prohibited, or when it is necessary to heat a small amount urgently. For example, heating milk for feeding, heating for tea, heating other beverages, heating retort food (eg, soup, curry roux, stew, etc.), and placing wet towels in heat-resistant bags It is possible to make a heated steam towel, or to make a rice cake in a similar heat-resistant bag, for example, with cold or rice and water, or to cook simply by heating the utensils. Furthermore, it can also be sterilized by putting a baby bottle, chopsticks, knife, fork, spoon, etc. in this and heating. Of course, the present invention is not limited to these and can be used for many other purposes.

  In the above embodiment, the bag 4 is made of a material containing aluminum. However, the present invention is not limited to this, and other materials such as plastic may be used as long as it is a heat-resistant bag. Further, the paper sheet 5 does not have to cover the entire outer periphery except the gusset 4a of the bag 4, and may be a part of the outer periphery of the bag 4 to be heated. The paper sheet 5 has a cross-sectional corrugated shape. The details of the corrugated corrugation are as shown in FIG. 6 (a). Includes one with flat paper affixed to one side of the corrugated paper and one with flat paper affixed to both sides of the corrugated paper as shown in the figure. In this case, there are a large number of gaps between the sheet 5 and the bag 4 or 7 or between the paper layers of the sheet 5 itself, and since air enters these gaps, a higher heat insulating effect is generated. The paper sheet 5 is attached to the outer periphery of the bag 4, but is not limited to the attachment, and may be provided on the outer periphery of the bag 4 by an appropriate method. Further, the material is not limited to the corrugated paper sheet, and may be any appropriate material as long as it is flexible, such as a paper sheet or a plastic sheet. .

  Moreover, in the said Example, although the temperature controlled with the hydrous exothermic agent 2 is about 90 to 100 degreeC, the temperature to control is not restricted to this, What is necessary is just to make it desired temperature. Therefore, when it is determined that the temperature desired to be controlled by the hydrolytic exothermic agent 2 is too high during the heating of the PET bottle, these temperatures may be set to lower temperatures. Furthermore, as the hydrous exothermic agent 2, a hydrous exothermic agent made by Kyodo Co., Ltd. consisting of powdered quicklime and powder aluminum is used, but the hydrous exothermic agent is not limited to this, Any hydrothermal exothermic agent may be used. Moreover, although this water-type exothermic agent 2 is contained in the water-permeable bag 2a, it may be taken out from the bag 2a when the heater is used, and only the water-type heat-generating agent 2 may be put in the bag 4 or the auxiliary bag 8. .

  Moreover, although the water bag by the Sakakibara Refrigeration Co., Ltd. is used as the water bag 3a which put the water 3, this water is not limited to this, What is necessary is just to show the effect of this application. Moreover, in the said Example, although the water bag 3a which put the water 3 of the quantity suitable for the said hydrous exothermic agent 2 is made into the main body 1 and the said hydrous exothermic agent 2, it is not restricted to this, A main body The portable simple heater can be constituted by 1 and the hydrolytic exothermic agent 2, and water can be appropriately procured separately. In particular, in that case, it is preferable to display the amount of the water-based exothermic agent 2 and the amount of water corresponding to the predetermined heating temperature. In addition, when heating the bottle 6 of the soft drink, the flat bag 2a of the hydrolytic exothermic agent 2 is placed on the bottom surface of the bag 4 of the main body 1, and the bottle 6 is erected thereon. The bag 2a into which the heat generating agent 2 is placed is not limited to a flat one, and may be a three-dimensional one. Also, the bag 2a is not limited to the bottom surface and is not limited to the bottom surface. It may be arranged in such a manner.
