Description

  This invention can be used indoors and outdoors, in the event of a disaster, etc., for drinking water for hot tea, for infants' milk, etc., and for heating and drinking food such as liquor during travel and sports watching, etc. The present invention relates to a portable portable heater that can be easily carried.

  Conventionally, boiling hot water for coffee and boiling hot water for instant noodles, such as hiking outdoors, have been performed as a daily routine. It is also a common sight to watch sports while drinking warm liquors outdoors in winter.

  In addition, when the damage of a disaster such as an earthquake is great, the supply of lifelines such as electricity, gas and water is stopped, and normal life cannot be made. Even in such a disaster, it is necessary to boil the hot water used to make infants' milk, and in such cases, especially during winter, hot water tea etc. should be provided to victims. Will be healed and delighted by the victim.

  On the other hand, the cup liquor with porridge function has the function of using the fact that high heat is generated when water is applied to the lime, and reacting other exothermic agents, but these are in each product. It is provided as a single unit and is not very versatile.

In addition, there is one in which a liquid food such as a lunch box or sake is enclosed in a cooking container, and the lunch box or sake is warmed by a heating agent that is a heating device incorporated in the cooking container. As these exothermic agents, there are used exothermic reactions of chemical substances, for example, those utilizing a reaction of adding water to oxides. Further, there is a method in which a thin heating element is attached to one surface of a sheet and wound around the outer periphery of an object to be heated.
JP 2003-342558 A Utility Model Registration No. 3109136

  However, the former is an invention related to an exothermic agent, and when a lunch box or sake is heated using this exothermic agent, it is necessary to separately prepare a cooking container or an alternative. In normal times, it is easy to prepare these items, but it is not easy at the time of a disaster, and even if prepared, it is estimated that it will take time. In the latter case, if there is unevenness in the outer shape of the object to be heated, the object to be heated cannot be erected by itself, or if it is unstable even if it is erected, the heating will be uneven. Yes, stable heating cannot be achieved, and sufficient effects cannot be expected.

  Meanwhile, many people frequently purchase and use 350cc or 500cc vertical heat-resistant PET bottles containing drinking water or the like at supermarkets and convenience stores. These PET bottles are robust, will not break in a little, and have a cap that can be opened and closed, making them ideal for carrying and storing drinking water. Therefore, if there is a portable simple heater that can easily heat such heat-resistant PET bottles and cans, it will be of great utility during outdoor activities and disasters.

  Therefore, the present invention provides a portable simple heater that can warm a cheap, efficient, and safe can, such as a can containing drinking water, a heat-resistant plastic bottle, etc., using a stable cup. The problem is solved by providing.

  The invention according to claim 1 is a heater that heats the object to be heated by adding the heat-generating exothermic agent, water, and the object to be heated in the container, and heating the object to be heated. Use a plastic cup, cover the opening of the cup with a substantially cylindrical cap whose upper surface is open, and put the hydrous exothermic agent, water, and the object to be heated in the cup, and add the hydrous exothermic agent. When heating the object to be heated by generating heat, the inner peripheral edge of the upper surface opening of the cap and the outer peripheral surface of the heated object are close to each other, and the inner peripheral surface of the cup and the outer peripheral surface of the heated object It was set as the portable simple heater which provided the clearance gap between.

  The invention according to claim 2 is the portable simple heater according to claim 1, wherein the cylindrical side surface of the cap has a tapered shape that becomes narrower toward the top. The invention according to claim 3 is the portable simple heater according to claim 1 or 2, wherein the inner peripheral edge of the opening on the upper surface of the cap is a protruding edge that protrudes inward for a fixed length. .

  The invention according to claim 4 is the invention according to any one of claims 1, 2, or 3, wherein the size is determined by correlating the calorific value of the hydrolytic exothermic agent with the size of the upper surface opening of the cap. The portable simple heater was used. The invention according to claim 5 is the portable simple heater according to any one of claims 1, 2, 3 or 4 in which the cap and the container are integrally provided.

  According to the first, second, third, fourth, and fifth inventions, since the cup made of paper or plastic is used as the container, the original cup has the concept that it has a sense of stability. Together, it looks very stable and can be used with peace of mind. In fact, these cups are structurally stable for the purpose of placing them on a table or the like. Moreover, such a cup is easy to obtain, and it is possible to easily obtain a portable simple heater having a low cost and a simple configuration. Thereby, the portable simple heater which is easy to reach a lot of people's hands can be provided.

  As a result, heat-resistant PET bottles, bottles, cans, baby bottles and the like containing drinking water and food can be heated safely and stably by adding appropriate water outdoors. In addition, since no fire is used, it can be used with peace of mind even in places where fire is strictly prohibited.

  In addition, the cup as a container is heated with the heating agent when heated, but is placed in an appropriate place such as a table and heated, so there is no need for human touch and it is safe.

  In addition to the above effect, according to the first aspect of the present invention, the inner peripheral edge of the upper surface opening of the cap and the outer peripheral surface of the heated object are close to each other, and the inner peripheral surface of the cup and the heated object Further, according to the invention of claim 2, since the cylindrical side surface of the cap is tapered so as to go upward, the gap of claim 3 is further reduced. According to the invention, since the inner peripheral edge of the opening on the upper surface of the cap is protruded inward for a certain length to form a protruding edge, when an object to be heated is inserted into the container, The gap between the periphery and the outer peripheral surface of the object to be heated is narrowed so that water vapor generated from the heating agent is difficult to escape from the container, and it is also difficult for cold air from entering the outside to reduce the loss of water vapor by convection in this container. Yes, increase thermal efficiency, and in turn increase heating performance. In addition, since the gap between the inner peripheral edge of the upper opening of the cup and the outer peripheral surface of the object to be heated is narrow in this way, it is difficult for water vapor to spill out of the container or water to spill out. Even if it falls, it is safe without spilling a lot of water around it.

  In addition to the above effect, according to the invention of claim 4, since the respective calorific values of the water-type exothermic agent and the size of the opening of the cap are correlated, the respective sizes are determined. In the case of 10 g of the agent, the diameter of the opening of the cap is set to 58 to 67 mm for heating a can or a pet bottle having a capacity of 200 cc. In the case of the heating agent 20 g, the diameter of the opening of the cap is set to 68 to 75 mm and the capacity of 350 cc For heating cans and pet bottles, the cans and pet bottles to be heated can be heated efficiently and reliably without excess or deficiency.

  In the invention of claim 5, since the cap and the container are integrally provided, it is not necessary to prepare a separate container. Therefore, the portable simple heater can be easily provided and is convenient.

  In a heater that heats the object to be heated by putting the water-type exothermic agent, water, and the object to be heated into a container, and heating the object to be heated, a paper or plastic cup is used as the container. The cup opening is covered with a substantially cylindrical cap having an upper surface open, and the water heating agent, water, and an object to be heated are placed in the glass to heat the water heating agent, and the water to be heated. When heating an object, the inner peripheral edge of the upper surface opening of the cap and the outer peripheral surface of the object to be heated are close to each other, and a gap is provided between the inner peripheral surface of the cup and the outer peripheral surface of the object to be heated. Therefore, it looks very stable and can be used with confidence. In fact, these cups are structurally stable for the purpose of placing them on a table or the like.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a state in which an object to be heated is heated using a portable simple heater (hereinafter simply referred to as “heater”) of the present invention, and FIG. 2 is a heater of the present invention. It is a perspective view which shows a cap. FIG. 3 is a cross-sectional view showing a state in which a hydrous exothermic agent is put into the paper cup of the heater of the present invention, and FIG. 4 shows the hydrous exothermic agent at the bottom of the paper cup of the heater of the present invention. It is sectional drawing which shows the state mounted. FIG. 5 is a cross-sectional view showing a state where a cap is put on the upper surface opening of the paper cup of the heater of the present invention, and water is poured from the upper surface opening of the cap, and FIG. 6 uses the heater of the present invention. It is sectional drawing which shows the state which is heating the to-be-heated material.

  As shown in FIGS. 1 and 6, the heater A of this embodiment covers a paper cup 1 having a size that can accommodate more than half of the can B that is an object to be heated, and an upper surface opening 1 a of the paper cup 1. The cap 2, the hydrous exothermic agent 3 contained in a substantially flat water-permeable bag 3 a, and the water bag 4 a containing water 4 are configured.

  As the paper cup 1, an existing one that is generally commercially available is used. As shown in FIG. 2, the cap 2 is made of heat-resistant plastic and has a transparent cylindrical shape. The inner peripheral edge of the opening 2a on the upper surface slightly protrudes inward to form a protruding edge 2b. The side surface is formed in a taper shape that becomes narrower toward the upper part, and an annular locking step 2c is provided on the outer peripheral edge of the lower part, and the upper surface opening 1a of the paper cup 1 is covered with this cap 2. It is difficult to come off.

  The hydrous exothermic agent 3 contained in the substantially flat water-permeable bag 3a 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, an exothermic agent manufactured by Eldyne Co., Ltd. is used (see JP 2003-342558 A). 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 3a which puts these powder quicklime and powder aluminum uses the water-permeable thing.

  Further, the water bag 4a containing the water 4 is heated to generate calcium aluminate by reacting with the powdered quicklime in the hydrous exothermic agent 3. 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 heater A will be described. First, a paper cup 1, a cap 2, a hydrous exothermic agent 3 put in a flat bag 3a, and a water bag 4a containing an amount of water 4 corresponding to the hydrous exothermic agent 3 are prepared as one set. .

  Then, the paper cup 1 is taken out from the inside, and the paper cup 1 is set up in a flat place. As shown in FIGS. 3 and 4, the hydrous exothermic agent 3 from the upper surface opening 1 a of the paper cup 1. Is placed on the bottom surface inside the paper cup 1, and the cap 2 is placed over the top opening 1a. Then, as shown in FIG. 5, the water bag 4 a is broken to put water 4 into the paper cup 1 from the upper surface opening 2 a of the cap 2, thereby causing the water heating agent 3 to generate heat. Thereafter, as shown in FIG. 1 and FIG. 6, a pot B for drinking water, which is an object to be heated, is inserted from the upper surface opening 2 a of the cap 2, placed on the hydrolytic exothermic agent 3, and erected. .

  The water 4 put in the paper cup 1 reacts with the powdered lime in the hydrous exothermic agent 3 and the water 4 to cause a first exothermic reaction to produce calcium aluminate, and this produced aluminate Calcium and the powdered aluminum in the hydrous exothermic agent 3 react with each other to cause a second exothermic reaction. The hydrous exothermic agent 3 generates heat, and the paper cup 1 is filled with water vapor C as shown in FIG. The can B is heated together with the water vapor C. In this way, there is a gap filled with water vapor C between the inner peripheral surface of the paper cup 1 and the outer peripheral surface of the can B.

  At this time, the side surface of the cap 2 is provided in a tapered shape, and the gap between the inner peripheral edge of the opening 2a and the outer peripheral surface of the can B is narrowed by the protruding edge 2b in the opening 2a of the cap 2, The water vapor C is difficult to be discharged to the outside (see FIG. 6), and is convected in the paper cup 1. Moreover, the possibility of cold air entering from the outside is low, and the influence of heat loss received from the outside can be blocked. Thereby, the loss of water vapor C can be reduced in the paper cup 1, the thermal efficiency can be improved, and the heating performance can be improved. Moreover, since the clearance gap between the inner periphery of the opening part 2a of the said cap 2 and the outer peripheral surface of the can B is narrow, even if the said heater A falls down, an internal water is hard to spill and is safe. is there.

  When this can B has a capacity of 350 cc, it rises to approximately 52 ° C. in 6 to 7 minutes and becomes ready to drink. Moreover, it can heat for about 15 minutes in this state. Further, at this time, the outer periphery of the paper cup 1 has a heat retaining effect on the inner can B and is efficiently heated.

  Further, at this time, the heat generation amount of the hydrolytic exothermic agent 3 and the size of the opening 2a of the cap 2 can be correlated to determine the respective sizes. For example, in the case of 10 g of exothermic agent, the diameter of the opening 2a of the cap 2 is set to 58 to 67 mm for heating a 200 cc capacity can. In the case of the heat generating agent 20g, the diameter of the opening 2a of the cap 2 is set to 68 to 75 mm for heating a can with a capacity of 350 cc. Thereby, the can and pet bottle which are to-be-heated objects can be heated efficiently and reliably without excess and deficiency.

  If these heaters A 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 breastfeeding, heating for tea, heating other beverages, and making a heated towel in a heat-resistant bag instead of the can B, and heating the ingredients You can also do simple cooking. Of course, the present invention is not limited to these and can be used for many other purposes.

  In the above embodiment, the paper cup 1 may be of any material, double paper, an embossed air layer to provide high heat insulation, and a paper cup. Instead of 1, a heat-resistant plastic cup can also be used. Moreover, although the latching step part 2c is provided in the outer peripheral edge of the lower part of the cap 2, this latching step part 2c does not need to be.

  In the embodiment, the cap 2 is put on the opening 1a of the paper cup 1 after the water-type exothermic agent 3 is put into the paper cup 1, but the cap 2 is covered with the opening 1a of the paper cup 1. Of course, the hydrous exothermic agent 3 may be put into the paper cup 1 through the opening 2a of the cap 2 after being covered. In the case where the paper cup 1 and the cap 2 are integrally formed, this latter form is obtained.

  Furthermore, although the temperature controlled by the hydrous exothermic agent 3 is about 90 ° C to 100 ° C, the temperature to be controlled is not limited to this, and may be a desired temperature. Therefore, when it is determined that the temperature desired to be controlled by the hydrolytic exothermic agent 3 is too high when heating a can or a plastic bottle, these temperatures may be set to lower temperatures.

  Furthermore, as the hydrous exothermic agent 3, a hydrous exothermic agent made of Eldine Co., which is composed of powdered quicklime and powdered aluminum is used, but the hydrous exothermic agent 3 is not limited to this. Any hydrolytic exothermic agent may be used. Moreover, although this water-type exothermic agent 3 is contained in the water-permeable bag 3a, when the heater is used, it may be taken out from the bag 3a and only the water-type heat-generating agent 3 may be put in the paper cup A.

  Moreover, although the water bag by the Ebara Refrigeration Co., Ltd. is used as the water bag 4a which put the water 4, 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 4a which put the water 4 of the quantity corresponding to the said water-type exothermic agent 3 was put together with the paper cup 1, the cap 2, and the water-type heat-generating agent 3, it is set as one set. Not limited to this, the paper cup 1, the cap 2 and the hydrolytic exothermic agent 3 may constitute the heater A, and the water 4 may be separately appropriately procured. In particular, in that case, it is preferable to display the amount of the hydrous exothermic agent 3 and the amount of water corresponding to the predetermined heating temperature.

  Further, in this embodiment, as shown in FIGS. 1 and 6, when the can B is put into the heater A, the upper portion of the can B slightly protrudes from the upper surface opening 2a of the cap 2 on the heater A. However, substantially all of the can B may be accommodated in the heater A, and is not limited thereto, and the upper portion of the can B further protrudes from the upper surface opening 2a of the cap 2 than the above, The same effect can be obtained even when the upper portion of the can B is positioned slightly below the upper surface opening 2a of the cap 2.

  In the above-described embodiment, the side surface of the substantially cylindrical cap 2 is tapered. However, the present invention is not limited to this, and the side surface of the cap 2 is not formed in a tapered shape. It is also possible to provide a protruding edge with the upper edge protruding inward for a fixed length, and the inside edge of this protruding edge may be the upper surface opening.
