Description

  The present invention relates to a heating container capable of heating an object to be heated by a simple means in the outdoors or in an emergency where an appropriate heating means cannot be prepared for heating an object.

  At present, foods including beverages, especially processed foods, are often distributed in a sealed state in metal, synthetic resin, paper or the like because they can be easily stored and transported for a long time. They are so-called canned foods, canned beverages, beverages in aluminum laminated bags, foods, plastic bottle beverages, paper-packed beverages and the like (hereinafter abbreviated as “packed food”). For these packed foods, the food inside may be heated at the stage of processing, but at the stage of sale, the food inside is the same as the outside air temperature, and in cold seasons such as winter. The food inside is cold.

  On the other hand, for these packed foods, if the food itself is warm and eaten, it is considered to be warm by eating warm food in cold weather, or you can eat and drink with cold food as it is It can be difficult. For example, when the food is a beverage, it is sake, shochu, coffee, tea, soup, etc., and when the food is a mixture of solids and liquids or fluid food, it is for tofu, oden, miso soup, curry roux, meat spaghetti The roux etc.

  As a container for heating such an object to be heated, the name of “the apparatus for heat adjustment” of the invention of Patent Document 1 and the name of “the container for heating” of Patent Document 2 have been filed. Also, not only packed foods, but also hand towels and paints, there are some which are easier to use and easier to use when warmed. Therefore, hereinafter, the packaged food and the object that should be warmed, such as a towel, will be referred to as a heated object.

Special table 2012-500756 gazette JP 2014-124415 A

  However, the invention described in Patent Document 1 has a structure in which a container and a heating mechanism (a reaction tank in Patent Document 1) are integrated. For this reason, unless the food inside is necessarily heated, it is not preferable to sell the object to be heated in such a container because the manufacturing price of the object to be heated increases. Therefore, when enclosing the same food, it is necessary to produce two types with and without a heating mechanism, which is not preferable in terms of manufacturing and inventory.

  Moreover, about invention of patent document 1, a heating mechanism is provided so that it may protrude in the center part inside the container itself. For this reason, there is a restriction on the place where the food can be put, and in the case of solid or fluid food, there is a problem that it is not suitable for eating and drinking as it is.

  Furthermore, in the heating mechanism of the invention described in Patent Document 1, the exothermic agent (quick lime as the reactant R1 in Patent Document 1) is on the upper side with the container opening (drinking port) facing upward, and the exothermic agent generates heat. An exothermic initiator that initiates the chemical reaction (water as reactant R2 in Patent Document 1) is disposed on the lower side. For this reason, in order to cause the exothermic reaction when the lower water is mixed with the upper quicklime or to continue the heat generation, the container opening portion is turned downward and the container is turned upside down. There was a need.

  In a state where quick lime is generating heat with the container reversed, the water added to the quick lime becomes high-temperature steam, but it expands inside the reaction tank, so that the reaction tank can withstand the internal expansion. Must be. Therefore, there is a problem that the reaction tank must be made of a material having a pressure resistance.

  In order to continue the heat generation, the reaction tank is in the upper part in a state where the container is reversed, and heat exchange is performed with food (beverage) in contact with the outer surface of the reaction tank. However, in the reaction tank on the upper side, the effect of heat exchange due to the convection of food (beverage) inside the container becomes partial, and in order to sufficiently heat the food (beverage), the amount of exothermic agent and water is reduced. There was a problem that we had to do more.

  This operation of reversing the container is difficult for first-time users, so if you unintentionally open the mouthpiece without reading the instructions, you will not be able to reverse the entire container. There was a problem that heating could not be performed. Also, if you do not read the explanation of the heating time that needs to be continued for a predetermined time, if you try to drink quickly and stop reversing in the middle of heating, there is a problem that heating is not possible or insufficient there were.

  In Japan, the “Law Concerning Separate Collection and Promotion of Recycling of Containers and Packaging” was enacted in 1995, and from the viewpoint that recycling is required for containers and packaging, Regarding the invention, there is a problem that the apparatus for adjusting the heat is formed by integrally forming various members such as metal, resin, and quicklime, and is difficult to separate, so that it is not suitable for recycling.

  Since the main purpose of the invention described in Patent Document 2 is to reduce the volume other than when in use, a paper container is folded like an origami to create a paper heating container, and the paper container is folded and made of paper. The inside of the container is heated with a separately prepared exothermic agent such as quicklime and water, which is placed inside the paper container to heat the plastic bottle containing the drink. There was a problem that work took time. In addition, regarding the water to be put into the paper heating container, it is necessary to measure the amount of water specified by the user with a measuring cup etc. Without work, there was a problem that it could not be heated sufficiently.

  Furthermore, since quick lime is only thrown in the inside of a paper container, the quick lime may stick locally to the PET bottle inside the paper container. In this case, quick lime is locally heated with respect to the plastic bottle, and there is a problem that the heating of the drink inside the plastic bottle may not be spread over the whole.

  Furthermore, when separating and throwing away PET bottles and paper containers that have been drunk, it is necessary to remove the PET bottles from the containers. In this case, if quicklime is locally adhered to the PET bottle as described above, a solution of slaked lime generated after reacting with quicklime or water is attached to the outer periphery of the PET bottle. Since this quicklime or slaked lime solution is strongly alkaline, there is a problem that it is dangerous if it adheres to the skin.

  In order to solve the above problems, the present invention takes the following technical means.

In the heating container according to the first aspect of the present invention, an object to be heated is accommodated therein, and when the object to be heated has an opening, an upper opening closely contacts the opening, and a side surface of the object to be heated and a predetermined side A cylindrical member having an interval and having a lower opening;

For example, a combination of calcium chloride and water. In addition, powdered aluminum is mixed with powdered quicklime of the exothermic agent 42, water and quicklime react to generate calcium hydroxide and heat of reaction, and in the second stage, powdered aluminum, calcium hydroxide and water react. Further, reaction heat may be generated.

  A method for assembling the article 6 to be heated into the heating container 1 will be described with reference to FIG. In addition, the to-be-heated material 6 is what is called a can drink in which foods, such as coffee, tea, liquor, and soup, were stored in metal cans, such as iron and aluminum. In order to drink the can beverage of the article 6 to be heated, a pull-top type opening means is provided on the upper portion of the can so that it can be opened without using a can opener. Regarding opening of the can, depending on the content of the article 6 to be heated, the entire upper part of the can may be opened, or only a part of the upper part of the can may be opened as a drinking mouth. The opening method may be a steion type.

  The cylindrical member 10 is in a state of being separated into an upper cylindrical member 11 and a lower cylindrical member 21, and for the first container member 30 and the second container member 40, the heat generation initiator 32 and the heat generating agent 42 are sealed, respectively. It is in a state. First, the first container member 30 is put into the lower cylindrical member 21 from the upper opening 22 so that the top 34 is on the top. On the inner surface of the lower cylindrical member 21, an overhang receiving portion 28 is provided in a “substantially V-shaped” shape inside a predetermined thickness, and a receiving portion of the leg portion 36 is provided at a position corresponding to the leg portion 36. When the six leg portions 36 are accommodated in the six receiving portions 28, the first container member 30 is attached to a predetermined position of the lower cylindrical member 21 (for the relationship between the receiving portion 28 and the leg portion 36). , See FIG.

  Next, the heated object 6 is put into the lower cylinder member 21 to which the first container member 30 is attached from the upper opening 22 with the opening means provided upward, and the upper opening of the lower cylinder member 21 is placed. The portion 22 is inserted inside the lower opening 12 of the upper cylindrical member 11, and a claw 23 with a retaining prevention is inserted into the square hole 13 to connect the upper cylindrical member 11 and the lower cylindrical member 21.

  Finally, the second container member 40 in which the heat generating agent 42 is sealed is inserted into the lower opening 24 of the lower cylinder member 21 (cylinder member 10), and the second container member 40 is connected to the lower cylinder member 21 by the protrusion 27 and the groove 46. The heating container 1 in which the object to be heated 6 is housed is fixed in a predetermined position inside.

  FIG. 2 is an external view after the assembly of the heating container 1 containing the article 6 to be heated. The appearance of the heating container 1 containing the article to be heated 6 is the state of the cylindrical member 10 in which the upper cylindrical member 11 and the lower cylindrical member 21 are combined, and what is visible on the outside is an unsealing means that looks through the upper opening 15. The upper part of the heated object 6 provided, the side wall part 14 of the upper cylinder member 11 and the side wall part 25 of the lower cylinder member 21, which are not shown, but at the bottom part, the bottom part 44 of the second container member 40. become.

  In addition, the side wall portion 14 of the upper cylindrical member 11 has a square hole 13 in which a retaining prevention claw 23 is fitted, and the width of the square hole 13 is formed wider than the width of the retaining prevention claw 23. Therefore, holes that are partially opened are formed at both ends of the square hole 13. This partially opened hole is a hole through which heat is generated in the heating container 1 described later and the vapor of the heat generation initiator 32 heats the article 6 to be heated, and then is gradually removed outside.

  In order to explain the internal relationship of the heating container 1 in a state where the heating container 1 of FIG. 2 is assembled, a description will be given using the cross-sectional view of FIG. 3 showing a state cut along AA of FIG. In addition, when cut | disconnected by AA of FIG. 2, in FIG. 3, the leg part 36 of the 1st container member 30 and the receiving part 28 inside the lower cylinder member 21 will be cut | disconnected. For this reason, when the heating of the article 6 to be heated, which will be described later, is described, the leg portion 36 and the receiving portion 28 may get in the way, and at the BB that is a cutting portion where the leg portion 36 and the receiving portion 28 are not present. The cut location is also shown in FIG.

  FIG. 3 is a cross-sectional view showing a state cut along A-A in FIG. 2. In FIG. 3, the object to be heated 6 is indicated by a dashed-dotted imaginary line because it is difficult to understand when the object to be heated 6 is present. First, the state of the article 6 to be heated inside the heating container 1 will be described.

  About the top part in which the opening means of the to-be-heated material 6 is provided, it is provided in the outer periphery of the upper part of the can of the to-be-heated material 6 in the double location of the upper side opening part 15 of the upper cylinder member 11. It is in a state of fitting into the crimped portion, and is formed so that the vapor of the heat generation initiator 32 does not leak from the outer periphery of the upper portion of the can of the article 6 to be heated. If the shape of the can of the object to be heated 6 cannot sufficiently adhere to the doubled portion of the upper opening 15, packing is applied to the doubled portion of the upper opening 15 by packing. You may make it contact | adhere with the upper side of the heating thing 6. FIG.

  Next, with respect to the bottom side of the object 6 to be heated, the bottom of the can is usually in a state where the central portion of the bottom is recessed, and the top surface of the top portion 34 in which the upper surface of the first container member 30 swells into a spherical shape is covered. The center of the bottom of the heated object 6 will be pushed. And since the 1st container member 11 and the 2nd container member 21 are couple | bonded so that it cannot isolate | separate easily by the two sets of square holes 13 and the nail | claw 23 with a retaining prevention, the double of this upper side opening part 15 is carried out. The heated object 6 is held in the heating container 1 so as not to be rattled by the portion that becomes, and the top part 34 whose upper surface swells in a spherical shape. Therefore, dimensional accuracy is obtained with respect to the dimension from the doubled portion of the upper opening 15 to the top of the top part 34 whose upper surface swells in a spherical shape in accordance with the outer dimension of the article 6 to be heated. Is formed.

  And if the to-be-heated object 6 is hold | maintained by the location where the upper side opening part 15 became double, and the top part 34 which the upper surface expanded spherically, the perimeter of the outer peripheral side surface of the to-be-heated object 6 and the lower part The inner surface of the cylindrical member 21 (including a part of the upper cylindrical member 11) has a predetermined gap (5 to 10 millimeters).

  The first container member 30 in which the heat generating initiator 32 is sealed inside the first container 31 has six legs 36 extending around the first container member 30 inside the side wall 25 of the lower cylindrical member 21. It is guided by the six receiving portions 28 provided, and is attached so as to keep the distance from the lower opening 24 of the lower cylindrical member 21 at a predetermined position. Accordingly, the downward movement of the first container member 30 in the lower cylindrical member 21 is restricted, and at the same time, the upward movement of the first container member 30 is coupled to the heated object 6 described above. It is regulated by the relationship between the tubular member 11 and the lower tubular member 21. Thus, the first container member 30 is attached so as not to move at a predetermined position inside the lower cylindrical member 21.

  The second container member 40 in which the heat generating agent 42 is sealed inside the second container 41 includes a groove 46 on the outer periphery of the bottom 44 of the second container member 40 and the vicinity of the lower opening 24 of the lower cylindrical member 21. A plurality of protrusions 27 provided on the inner periphery of the side wall portion 25, the lower surface of the bottom portion 44 of the second container member 40 closes the lower opening 24 of the lower cylindrical member 21, and the side wall portion of the lower cylindrical member 21. 25, the flange 47 of the second container member 40 is attached at a position to look into. The second container member 40 is held at the lower end of the lower cylindrical member 21 by the groove 46, the protrusion 27, and the flange portion 47 unless a strong force is applied to the bottom portion 44.

  In the state of FIG. 3 (hereinafter referred to as a set state), the first container member 30 and the second container member 40 are held at predetermined positions inside the lower cylindrical member 21, and the heat generation initiator 32. Since the exothermic agent 42 and the exothermic agent 42 are separated from each other, the heat generation is not easily started, and can be transported in a packed state or carried out in a state of being taken out from the package. In addition, since the heat generation initiator 32 and the heat generation agent 42 are sealed, it can be stored for a long period of time.

  Next, the case where the article 6 is heated from the set state will be described with reference to FIGS. FIG. 4 shows a state where the heating container 1 is lifted from the state shown in FIG. 3 and the bottom portion 44 of the second container member 40 is pushed with a strong force from the lower side with a finger or a finger force is difficult to enter. It is a figure at the time of operation which presses against the corner of a chair or a chair. When the bottom portion 44 is pushed toward the inside of the heating container 1, the protrusion 27 of the lower cylindrical member 21 entering the groove 46 of the second container member 40 is released, and at the same time, the flange portion 47 of the second container member 40 is The second container member 40 slides inside the lower cylindrical member 21 by being broken or bent at the end of the side wall portion 25 of the lower cylindrical member 21.

  In addition, about the protrusion dimension of the part which the collar part 47 protruded, and the shape of the part which protruded, when predetermined strong force (for example, 100-150N) is applied, it fractures | ruptures or bends. It is adjusted and formed as follows. For example, in order to reduce the thickness of the protruding portion, or to make it easy to break or bend, there is a method of providing a shallow groove. Further, the depth of the groove 46 and the height and width of the protrusion 27 are also adjusted in the same manner.

  In the state of FIG. 4, the second container member 40 is in contact with the first container member 30. The seal member B49 of the second container member 40 and the seal member A39 of the first container member 30 are in contact with each other, so that the side wall portion 35 of the first container member 30 is larger than the diameter of the side wall portion 45 of the second container member 40. Since the diameter is smaller, the seal member B is pushed toward the inside of the second container member 40 by the side wall portion 35 of the first container member 30.

  This is because the interval between the seal member A39 and the seal member B46 in the set state is adjusted to be 0.5 to 1.5 millimeters, and the interval from the tip of the opening member 48 to the seal member B49 is Since it is 2 to 3 millimeters, the seal member B49 is first pushed by the side wall portion 35 of the first container member 30.

  As a result, the seal member B49 is pulled and the seal member B49 is pulled and the opening 43 of the side wall 45 is formed depending on the material and thickness of the seal member B49 and the degree of welding between the seal member B49 and the tip of the side wall 45. Fracture starts from the location welded on the side. The spacing between the sealing member A39 and the sealing member B49 and the spacing between the sealing member B49 and the tip of the opening member 48 are in such a relationship, so that the water of the heat generating initiator 32 can be sealed more safely. In addition, the rupture around the seal member B49 can be performed before the rupture of the seal member A, and the heat generating initiator 32 can be appropriately mixed with the heat generating agent 42.

  The state of FIGS. 5 and 6 in which the second container member 40 is further pushed in will be described. 5 and FIG. 6 are in the same position, but FIG. 5 is a cross-sectional view taken along the line AA in FIG. 2 and FIG. 6 is the same as FIG. It is BB sectional drawing. In FIG. 5 and FIG. 6, the plurality of opening members 48 are in a state of being broken with the sealing member B 49 and the sealing member A 39 being combined. Since the seal member B49 overlaps the seal member A39, the seal member B49 can be broken by the opening member 48 even when the welded portion around the seal member B49 starts to break.

  In this state, a plurality of holes are opened in the sealing member A39 by the opening member 48, and the water of the heat generation initiator 32 flows to the second container member 40 below. Since the opening is already opened in the corresponding portion of the seal member B49, the seal member B49 flows toward the heat generating agent 42 on the inner side of the second container member 40, and the heat generating agent 42 starts to generate heat. To do. Even when the amount of water flowing into the heat generating initiator 32 is large, the welding on the opening 43 side of the side wall 45 of the seal member B49 has already been broken, so heat is generated from the periphery of the seal member B49. The water of the initiator 32 flows into the heat generating agent 42.

  When the heat generating initiator 32 is mixed with the heat generating agent 42, heat generation starts, water in the heat generating initiator 32 evaporates, and steam is generated. The situation where the steam is generated will be described with reference to FIG. The steam generated in the second container member 40 moves upward from the periphery along the side wall 45 because the welding on the opening 43 side of the side wall 45 of the seal member B49 is broken. Then, the steam that has moved upward moves further upward between the inner surface of the side wall portion 25 of the lower cylindrical member 21 inside the heating container 1 and the side surface of the article 6 to be heated.

  The generated steam is transferred to the outside of the heating container 1 from the remaining holes, which are mostly blocked by the claw 23 with the retaining prevention of the lower cylindrical member 21 by the two square holes 13 of the upper cylindrical member 11. Get out. When the steam contacts the side surface of the object to be heated 6, the amount of heat of the steam moves to the object to be heated 6, and the object to be heated is heated. For this reason, the steam is discharged after being heat-exchanged, and since the closed square hole 13 is small, the steam is discharged while being sufficiently cooled.

  FIG. 7 shows a state in which the second container member 40 is pushed in until it comes into contact with the first container member 30. 7 is a cross-sectional view taken along the line BB in FIG. 2 as in FIG. The end of the opening 33 of the side wall 45 of the second container member 40 is in contact with the lower part of the six legs 36 of the first container member 30, and the inside of the lower cylindrical member 21 of the second container member 40. Sliding stops. All the water in the heat generation initiator 32 of the first container member 30 moves to the second container member 40 side, and the heat generation of the heat generation agent 42 continues.

  And the to-be-heated material 6 is heated for the heating time determined by the quantity of the heat generating agent 42 and the heat generation initiator 32 according to the heat capacity required for the to-be-heated material 6. During this time, the heating of the object to be heated 6 is not only from the side surface of the object to be heated 6 described above, but also the top part 34 of the first container member 30 is heated by the steam and comes into contact with the bottom of the object to be heated 6. The heat of the top 34 is also transmitted to heat the article 6 to be heated.

A specific example of heating in Example 1 will be described below.
About heated object 6 containing 180cc liquid (water),
When the water of the exothermic initiator 32 is 15 cc and the quick lime of the exothermic agent 42 is 7 g,
Start fever,
After 2 minutes the liquid temperature is 19.7 degrees Celsius,
After 3 minutes the liquid temperature is 30.1 degrees Celsius,
After 4 minutes the temperature of the liquid is 37.9 degrees Celsius,
After 5 minutes the liquid temperature is 42.5 degrees Celsius,
After 6 minutes, the temperature of the liquid reached 44.4 degrees Celsius.
The initial temperature of the liquid is 10.4 degrees Celsius, and the room temperature is 24.6 degrees Celsius.

  Since the heated object 6 is heated as described above, it is not necessary to reverse the heating container 1 containing the heated object 6. Further, the steam generated by mixing the exothermic agent 42 and the exothermic initiator 32 is effectively brought into contact with the outer surface of the object to be heated 6 without being confined in the first container member 30 and the second container member 40. Therefore, the amount of the exothermic agent 42 and exothermic initiator 32 used can be reduced.

  When the heated object 6 is eaten and eaten, when the heating container 1 and the object to be heated 6 contained therein are discarded, the lower cylinder member 21 looking into the square hole 13 of the upper cylinder member 11 is used. The upper cylinder member 11 and the lower cylinder member 21 can be easily separated by pushing the tip of the claw 23 with a retaining prevention into the heating container 1. Thereby, since the can of the to-be-heated material 6 is a metal, it can isolate | separate and can implement easily the recycling which can utilize resources effectively.

  In addition, the first container member 30 enters the second container member 40 and has a slight gap, but the internal heat generating agent 42 and the heat generation initiator 32 are not easily leaked to the outside. Thus, a strong alkaline solution is difficult to leak to the outside. And the container 1 for heating except the to-be-heated material 6 can be separated and thrown away as garbage which can be incinerated.

  The heating container 2 of the present invention will be described with reference to FIG. The difference from the heating container 1 of the first embodiment is that the seal member B49 is welded to the opening 43 of the second container member 40 of the first embodiment, whereas the second container of the heating container 2 is used. The seal member B is not welded to the opening 43 of the member 40a. FIG. 8 is a cross-sectional view at the same place as in FIG. In FIG. 8, the only difference is that there is no seal member B. Therefore, the same reference numerals are given in FIG.

  Even when the seal member B49 is not welded to the opening 43 of the second container member 40a, the heat generating agent 42 is still in a bag that allows water to pass through, while the bottom 44 of the second container member 40a. Since there are a plurality of opening members 48 in the periphery, and there is a sealing member A39 of the first container member 30 in the vicinity of the opening 43 of the second container member 40a, The movement of the heat generating agent 42 is regulated to some extent. And although there exists a possibility that a water | moisture content may be absorbed by sealing member B49, if it is used for a short time, there is no problem. Further, if the entire heating container 2 containing the article to be heated 6 is put in a plastic bag or hermetically packaged by shrink packaging or the like, it can be stored for a long time.

  Since the method for assembling the heating container 2 and the method for using the heating container 2 for heating are the same as those in the first embodiment, description thereof will be omitted.

  The heating container 3 of the present invention will be described with reference to FIG. The difference from the heating container 1 of Example 1 is that the heated object 7 to be heated inside the heating container 3 is a plastic bottle beverage. Even when the object to be heated 7 is a plastic bottle beverage, the heating container 3 is formed in accordance with the outer dimensions of the plastic bottle beverage, and the basic structure is the same. However, a packing made of natural rubber, synthetic rubber, synthetic resin foam, or the like is attached to the upper cylindrical member 11a in the double portion of the upper opening 15a. And the upper cylindrical member 11a so that there is no gap with the upper opening 15a so that the steam does not leak. The other structure of the heating container 3, the method of assembling the heating container 3, the method of using the heating container 3 for heating, and the like are the same as those in the first embodiment, and thus the description thereof is omitted.

  The heating container 4 of the present invention will be described with reference to FIG. The main difference from the heating container 1 of the first embodiment is that the cylindrical member 10b is formed as a single unit rather than being divided into two. By forming the cylindrical member 10b integrally, the cylindrical member 10b is formed by an upper opening 15 having a doubled portion, a narrow side wall 14a, a wide side wall 24a, and a lower opening 24. ing. And the groove | channel 16 is provided in the upper end of the wide side wall part 24a of the cylinder member 10b in the perimeter of the side wall part 24a. Further, a plurality of holes 17 are formed in the groove 16. The plurality of holes 17 are holes for releasing steam during heating.

  Next, the attachment method of the 1st container member 30a to the cylinder member 10b is different. A female thread 29 is formed on the inner surface of the cylindrical member 10b near the lower side of the wide side wall 24a. And the male screw 37 which fits the internal thread 29 as the whole six leg part 36a is provided in the part facing the inner surface of the side wall part 24a of the six leg part 36a of the 1st container member 30a. Since the other structures of the heating container 4 and the method of using the heating container 4 for heating are the same as those in the first embodiment, description thereof is omitted.

  An assembling method for putting the article 6 to be heated into the heating container 4 will be described. In addition, the to-be-heated material 6 is what is called a can drink in which foodstuffs, such as coffee, tea, and liquor soup, were stored in metal cans, such as iron and aluminum. In order to drink the can beverage of the article 6 to be heated, a pull-top type opening means is provided on the upper portion of the can so that it can be opened without using a can opener. Regarding opening of the can, depending on the content of the article 6 to be heated, the entire upper part of the can may be opened, or only a part of the upper part of the can may be opened as a drinking mouth. The opening method may be a steion type.

  About the 1st container member 30a and the 2nd container member 40, the heat_generation | fever initiator 32 and the heat generating agent 42 are the states sealed, respectively. First, from the lower opening 24 of the cylindrical member 10b, the side to which the opening means of the object to be heated 6 is provided is turned up, and is put inside the cylindrical member 10b, and is in close contact with the doubled portion of the upper opening 15 Insert until Next, it inserts from the lower opening part 24 of the cylinder member 10b with the top part 34 of the 1st container member 30a facing up.

  Thereafter, when the male screw 37 of the leg portion 36a of the first container member 30a comes into contact with the female screw 29 on the inner surface of the cylindrical member 10b, the first container member 30a is further moved back while rotating the first container member 30a. Then, the first container member 30a is moved (turned) to the place where the top 34 of the first container member 30a hits the object 6 to be heated. Thereby, the 1st container member 30a is attached to a predetermined position. Further, the article 6 to be heated can also be brought into close contact with the double portion of the upper opening 15.

  Finally, as in the first embodiment, the second container member 40 in which the heat generating agent 42 is sealed is inserted into the lower opening 24 of the cylindrical member 10b, and the second container member 40 is connected to the cylindrical member 10b by the protrusion 27 and the groove 46. The heating container 4 in which the object to be heated 6 is stored is completed.

  When the heated object 6 is eaten and eaten, when the heating container 4 and the object to be heated 6 contained therein are discarded, the portion of the groove 16 at the top of the cylindrical member 10b is thin, and at the same time Since the plurality of holes 17 are formed, the cylindrical member 10b can be divided by bending this portion. Thereby, since the can of the to-be-heated material 6 is a metal, it can isolate | separate and can implement easily the recycling which can utilize resources effectively. In addition, the first container member 30b enters inside the second container member 40 and has a slight gap, but the internal heat generating agent 42 and the heat generating initiator 32 are not easily leaked to the outside. Thus, a strong alkaline solution is difficult to leak to the outside. And the container 4 for heating except the to-be-heated material 6 can be separated and thrown away as incinerated garbage.

  In addition, about the attachment method of the 1st container member 30a to the cylinder member 10b, it does not attach with the female screw of the cylinder member 10b and the male screw of the 1st container member 30a as mentioned above, but it is a cylinder in the predetermined position of a cylinder member. It is also possible to implement the structure in which the six leg portions of the first container member are fastened with metal screws (small screws) from the outer peripheral side or the inner side of the member.

  As mentioned above, although this invention has been demonstrated based on the Example, this invention is not limited to the structure of these Examples at all. For example, since most of the objects to be heated are cylindrical, the heating container has been described as a cylindrical shape according to that, but even if the object to be heated is a quadrangular prism, a triangular prism, etc. It can be similarly implemented by making the configuration of the one container member and the second container member the same. In addition, the leg portions of the first container member are described as six. However, if the first container member can be stably attached to the inside of the cylindrical member, the number of the two or five or more. But it is possible.

  Furthermore, when the cylindrical member is cylindrical, the second container member is slid and pushed into the inside of the lower cylindrical member. A male screw may be attached to the outer periphery of the side surface of the container member, and the second container member may be pushed in while being rotated to the lower cylindrical member. In that case, it can be implemented by providing a groove that is rotated by a coin or the like outside the bottom of the second container member.
