Description

  The present invention relates to a container with a heating function that heats food and drink such as sake, soup and curry using an exothermic chemical reaction caused by a pyrogen and a reaction inducer.

  In general, sake is often drunk at room temperature or drunk or chilled. In particular, when drinking after chilling, you can enjoy delicious sake without sacrificing the flavor of sake by simply placing the sake in a refrigerator and cooling it for an arbitrary time. In addition, when you drink with sake, you can enjoy sake with a taste different from cold sake by changing the sake to a bottle of liquor and heating it with a hot water bath, sake bottle or microwave oven. You can enjoy various flavors because of the different flavors.

  However, when drinking sake in a bowl, it requires a means of heating the sake, so the problem is that you can only taste sake in the bowl only at homes, restaurants, hotels, etc. where there is a gas stand or microwave oven. was there. In addition, chilled sake does not lose its flavor even if the cooling time is long, so it can be sold at vending machines and can be drunk on the go. If it is too much, the balance of flavor will be lost and the smell of sake will become so bad that the taste will deteriorate.

In order to cope with such a problem, several inventions and devices have been disclosed.
For example, Patent Document 1 discloses a heating function that secures a high level of safety by providing a lid structure in which water vapor generated by an exothermic chemical reaction is easily discharged out of the container under the name “container with heating function”. An invention related to the attached container is disclosed.

Hereinafter, the technique disclosed in Patent Document 1 will be described with reference to FIG. FIG. 6 is a longitudinal sectional view showing a container with a heating function according to the prior art.
FIG. 6 shows a state in which the container with a heating function disclosed in Patent Document 1 is inverted, and a state in which the opening serving as a drinking mouth is placed below and the portion normally serving as the bottom is placed upward is shown. Show. As shown in FIG. 6, the container with a heating function includes a container main body 23 that contains a drinkable content 33 that is an object to be heated, a lid 32 that closes an opening serving as a drinking mouth, and a bottom surface of the container main body 23. A protective cap 31 having an opening closed, a peeling projection 31a at the inner central portion, and an arc-shaped slit (outer vent hole) 31b on the surface, and the protective cap 31 locked to the container body 23 The reaction chamber 24 contains a pyrogen 34 made of quick lime that has been crushed into small pieces. Further, the exothermic substance 34 is in contact with the contents 33 through the bottom wall 24a and the side wall 24b. Reference numeral 25 denotes a foamed shrink film covering the peripheral side surfaces of the container body 23 and the protective cap 31.

  Further, an annular wall (cylindrical vertical wall) 26b, a cylindrical side wall (cylindrical vertical wall) 26c, and an outer convex wall (upper wall) 27 are integrally formed in the opening of the reaction chamber 24 to induce reaction inside. A liquid container 26 containing the liquid 35 is latched and accommodated, and the reaction inducing liquid 35 is in contact with the exothermic substance 34 through a thin aluminum foil sheet 28. The sheet 28 is attached to the reaction chamber 24 with an adhesive. And the outer convex shape wall (upper wall) 27 produced thinly is pressing the projections 27b and 27c at the center of the outer convex shape wall (upper wall) 27 to form a plurality of Vs formed around the projection 27b. The recess 27a of the groove is easily inverted. That is, by pressing the protrusion 27b, the convex outer convex wall (upper wall) 27 as shown in FIG. 6 is deformed into a concave shape. Further, a push rod 29 provided with a circular cutting edge at the tip is fitted in the concave portion 27d of the protrusion 27c. When the protrusion 27b is pressed, the cutting blade at the tip of the push rod 29 breaks the sheet 28. The reaction inducing liquid 35 in the liquid container 26 flows into the reaction chamber 24 and starts an exothermic chemical reaction. Reference numeral 26 a is a vent hole (inner vent hole), and reference numeral 30 is a lid that closes the opening of the reaction chamber 24 and the liquid container 26.

  With the structure as described above, when the contents 33 are heated, as shown in FIG. 6, first, place the drinking cap downward and the protective cap 31 upward, and point the center of the protective cap 31 to the center. Press with etc. Then, the peeling protrusion 31a provided at the lower portion of the protective cap 31 peels or breaks a part of the lid 30, and the outer convex wall (upper wall) 27 is pressed to form a plurality of V-shaped groove recesses 27a. The push rod 29 which is deformed from the convex shape to the concave shape and is fitted to the protrusion 27c breaks the sheet 28 with the circular cutting edge at the tip. As a result, the reaction inducing liquid 35 in the liquid container 26 flows into the reaction chamber 24 and an exothermic chemical reaction is started, so that the container body 23 is inverted so that the drinking mouth comes upward. The exothermic substance 34 and the reaction inducing liquid 35 mentioned here are mainly quick lime and water, and water vapor and heat are generated by the reaction between the quick lime and water. After a while after the exothermic chemical reaction is started, the heat generated in the reaction chamber 24 heats the outer peripheral wall of the reaction chamber 24, that is, the bottom wall 24 a and the side wall 24 b, and is further conducted to the contents 33. Heat.

  Further, since the generated water vapor is discharged to the outside through the air hole (inner air hole) 26a above the liquid container 26 and the slit (outer air hole) 31b provided in the protective cap 31, the inside of the reaction chamber 24 is discharged. The high-pressure and high-pressure steam is not likely to blow off because the high-pressure and high-pressure steam are not blown out because the high-pressure and high-pressure water-vapor holes (inner-air holes) 26a and slits (outer-air holes) 31b are small. The heated object can be heated.

  Patent Document 2 discloses an invention related to a container with a heating function that can shorten the heating time of an object to be heated under the name of “a container with a heating function”.

Hereinafter, the technique disclosed in Patent Document 2 will be described.
The container with a heating function disclosed in Patent Document 2 is provided with a container body that contains an object to be heated, a liquid container that contains a reaction-inducing liquid, and a liquid container that contains the liquid container and contains a heat-generating substance, as in Patent Document 1. A reaction chamber, a lower lid and an upper lid closing the opening of the reaction chamber and the opening opposite to the reaction chamber, and a breaking member at the tip of the liquid container from the bottom to the inside of the container body The exothermic substance and the reaction inducing substance are in contact with each other through the sheet. For this reason, when the center of the lower lid is pressed with a finger, the push bar breaks the sheet and the reaction inducing liquid is mixed with the exothermic substance to cause an exothermic chemical reaction to heat the object to be heated on the same principle as in Patent Document 1. It has a structure to do. The reaction inducing liquid, exothermic substance, liquid container, reaction chamber, push rod, and sheet mentioned here are described as a liquid reaction aid, exothermic agent, inner container, exothermic chamber, operating body, and membrane member in Patent Document 2, respectively. Yes.

  In addition, in the container with a heating function of Patent Document 2, a protrusion for perforating the lower lid is provided on the outer surface of the bottom of the liquid container, and the reaction chamber is in a reduced pressure state. Along with the rupture, the reaction chamber is returned from the reduced pressure state to the normal pressure state. As a result, external air enters the reaction chamber, and accordingly, the reaction inducing liquid is drawn into the reaction chamber. Therefore, since a large amount of reaction inducing liquid is added to the exothermic substance as compared with Patent Document 1, the reaction rate of the exothermic chemical reaction is increased, and the object to be heated can be heated in a short time. Furthermore, since the water and the reaction inducing liquid generated by the exothermic chemical reaction are pushed back into the reaction chamber by the air flowing into the reaction chamber, there is an effect that these do not flow out to the outside.

  Patent Document 3 effectively uses high-temperature water vapor generated by an exothermic chemical reaction caused by an exothermic substance and an inducing substance (described as a reaction inducing liquid in Patent Document 1) under the name “heating container”. An invention relating to a heating container that can be used is disclosed.

Hereinafter, the technique disclosed in Patent Document 3 will be described.
The heating container in Patent Document 3 has substantially the same structure as the container with a heating function disclosed in Patent Document 1, and the exothermic substance and the reaction inducing liquid in the reaction chamber are layered, that is, a bag or the like is formed in the center of the exothermic substance. The reaction inducing liquid contained in the pack body is contained. And the exothermic chemical reaction is started by rupturing the pack body provided in the central part of the reaction chamber. Therefore, by using a three-layer structure in which the reaction inducing liquid is provided in the intermediate layer instead of the two-layer structure as in Patent Document 1, the area where the reaction inducing liquid contacts the exothermic material when the pack body is ruptured is increased. Thus, the exothermic chemical reaction can be reliably started.
Further, by mixing a heat-resistant diluting and heat-retaining material into the heat-generating substance, it can be used for both heating and heat-retaining an object to be heated by heat generated by an exothermic chemical reaction.

However, in the above-described conventional technique, in the invention disclosed in Patent Document 1, the exothermic chemical reaction by the exothermic substance and the reaction inducing liquid is easily caused by pressing the central portion of the protective cap with a finger or the like. However, since a plurality of slits are provided in the center of the flange of the liquid container provided below the protective cap in an arc shape, there is a possibility that the flexibility increases and it can be easily pressed. There is a problem that an exothermic chemical reaction starts when the central portion of the protective cap is pressed by mistake. Further, when an exothermic chemical reaction is caused, there is a problem in that it takes time and effort to press the protective cap with the container body upside down and then to reverse it again.
In addition, since the area of the sheet to be broken by pressing the central part of the protective cap is small and the reaction inducing liquid is added to the exothermic substance, the amount of outflow of the reaction inducing liquid from the sheet breaking portion is small, and the exothermic chemistry It took time to start and finish the reaction, and it took time to heat the contents, and there was a problem that the exothermic chemical reaction might not be started if the sheet was not successfully broken.
Further, since the reaction chamber is formed integrally with the container body and is not removable, the content can be heated only to a certain temperature, and the heating condition of the content cannot be adjusted. It was.

  In the invention disclosed in Patent Document 2, a large amount of liquid reaction assistance is generated by air taken into the heat generation chamber from the outside as the membrane member is broken by the operating body by keeping the heat generation chamber in which the heat generating agent is stored in a reduced pressure state. Since the agent is drawn into the heat generation chamber, the reaction rate of the exothermic chemical reaction is increased, so that the object to be heated can be heated in a short time, and water vapor or liquid reaction aid generated by the exothermic chemical reaction flows out to the outside. However, since the exothermic chemical reaction is started by pressing the bottom of the container body with a finger or the like as in Patent Document 1, there is a possibility that the exothermic chemical reaction may be started due to a malfunction. there were. Further, there is a problem with the inversion operation performed to start the exothermic chemical reaction and the problem that the heating condition of the object to be heated cannot be adjusted because the container body and the heat generating chamber are integrally formed. It was the same.

  In the invention disclosed in Patent Document 3, the structure in the reaction chamber is a structure in which a pack body such as a bag containing an inducing substance mixed with a heat-resistant dilution and heat insulating material is provided in the central part of the exothermic substance. When the pack body is ruptured, the area where the inducing substance contacts the pyrogen can be increased and the exothermic chemical reaction can be started reliably, and the heat generated by the exothermic chemical reaction can be maintained by keeping the container body warm. Although it can be used effectively, it has a structure in which a part of the pack body is penetrated by a material for exothermic operation, so the amount of the inducing substance flowing out into the reaction chamber is small, and it takes time to start and end the exothermic chemical reaction. There was a problem. In addition, similarly to Patent Document 1 and Patent Document 2, when an exothermic chemical reaction is caused, it is necessary to perform the reversing operation of the container body, and it is impossible to adjust the heating condition of the object to be heated in the storage chamber. There was also.

  Hereinafter, an embodiment of a container with a heating function according to the present invention will be described with reference to FIGS. 1 to 5.

FIG. 1 is a conceptual diagram of a container with a heating function according to the first embodiment of the present invention.
The container 1 with a heating function causes an exothermic chemical reaction with a container main body 4 that accommodates a container that accommodates an object to be heated, a lid 2 that is attached to the upper part of the container body 4 and holds the container that accommodates the object to be heated. And a reaction vessel 9 containing a heat-generating substance such as quicklime and a reaction-inducing substance such as water.
The lid 2 does not necessarily have a structure that completely covers and closes the upper part of the container body 4, and the lid 2 and the object to be heated are removed by cutting the central portion into a circular shape as in the present embodiment. When a product label or the like is inserted between the container and the container, the structure can be seen from the outside. Also, a female screw (not shown) and a male screw (not shown) are screwed on the inner peripheral surface of the lid 2 and the outer peripheral surface of the container main body 4, respectively. A male screw (not shown) and a female screw (not shown) to be screwed are respectively screwed on the inner peripheral surface of the container body 4, and the lid 2 and the reaction container 9 are screwed to the container 1 with a heating function. Has been.
The lid 2 and the container body 4 do not necessarily have a structure in which a male screw and a female screw are screwed on the inner peripheral surface and the outer peripheral surface, but rather have a structure that can be attached with one touch, for example, one It is desirable to provide a pair of protrusions and grooves on the peripheral surface and to be detachable by engaging them so that labor can be saved.
Reference numerals 3 and 10 are anti-slips for fingers when rotating the lid 2 and the reaction container 9, respectively, and reference numeral 7 is an anti-slip for preventing the container from dropping when drinking.
In addition, heating of the object to be heated is performed by high-temperature heating steam and heat generated by an exothermic chemical reaction that occurs in the reaction vessel 9 by mixing the exothermic substance and the reaction inducing substance. It is discharged from the communication hole 5 above the container body 4 through the body 4.

Although not shown in FIG. 1, a film is wound around the peripheral surfaces of the lid 2, the container body 4, and the reaction container 9. For this reason, the heating steam released from the communication hole 5 is stored in the steam reservoir 4a through a gap formed by the film and the flow path 6 on the side surface of the container body 4. Further, when a film is not particularly used, if a structure is provided to cover the communication hole 5 so that the steam is allowed to escape downward, the steam that is condensed and becomes water is stored in the steam reservoir 4 a by the flow path 6. It is possible to make it. The detailed structure of the container 1 with a heating function will be described with reference to FIG. Reference numeral 8 denotes a stopper for preventing the reaction vessel 9 from being pushed into the bottom of the vessel body 4 due to a malfunction. The stopper 8 includes a cut portion 8 a and is provided around the lower portion of the container body 4. The stopper 8 can be removed by putting a finger into the cut portion 8a and peeling off the end of the stopper 8 in the circumferential direction. Only after the stopper 8 is removed, the reaction vessel 9 is screwed into the inside of the vessel body 4 to start an exothermic chemical reaction.
In the present embodiment, the lid 2 and the container main body 4 are screwed. However, the present invention is not particularly limited to screwing, and any structure may be used as long as it is detachable. Further, the reaction container 9 does not necessarily need to be screwed to the container main body 4, and may be any structure that can move relative to the container main body 4 when the stopper 8 is removed. It is good.

  2 is a cross-sectional view taken along line AA in FIG. 2, the same parts as those described in FIG. 1 are denoted by the same reference numerals, and description of the configuration is omitted.

As described above, the heating function-equipped container 1 includes the lid 2, the container main body 4, and the reaction container 9, and these peripheral side surfaces are covered with the film 22. The film 22 is provided with perforations 22a and 22b at portions corresponding to the lower portion of the lid 2 and the upper portion of the stopper 8, and the film 22 can be partially removed from the heating function-equipped container 1 along these perforations. It can be done. And the uneven | corrugated shaped press member 14 which has the some hole 15 is provided in the bottom part of the container main body 4, It has a structure which can mount the container 11 which accommodated the to-be-heated material 12 on this. Reference numeral 13 denotes a sealing material that seals the opening of the container 11.
On the other hand, the reaction-inducing substance 20 is accommodated in the lower part of the reaction container 9 with the protrusions 21 standing on the bottom, and the exothermic substance accommodating part 16 in which the exothermic substance 17 is accommodated in the upper part of the reaction container 9 is formed by the sealing material 18b. It is housed with the sealed opening down. Further, a sealing material 18 a is provided between the reaction container 9 and the pressing member 14 of the container body 4 to prevent any possible leakage of the reaction inducing substance 20 from the reaction container 9.
Further, a projection 19 is provided at the center of the upper portion of the exothermic substance accommodating portion 16 and is embedded with a notch 16a around the head and a head 19a substantially flush with the closed portion of the exothermic substance accommodating portion 16. Yes. Reference numeral 9a denotes a locking portion that is provided around the inner peripheral surface of the reaction vessel 9 and locks the exothermic substance accommodating portion 16, but this is inadvertent in the reaction vessel 9 of the exothermic substance accommodating portion 16. If the frictional force between the exothermic substance accommodating portion 16 and the reaction vessel 9 is sufficient, it is not particularly necessary to provide it.

With this structure, when the stopper 8 is removed and the reaction vessel 9 is screwed into the vessel body 4 in the direction of arrow B, the pressing member 14 provided at the bottom of the vessel body 4 moves in the direction of arrow C, The sealing material 18a that partitions the inside of the container main body 4 and the reaction container 9 is pierced to press the upper portion of the exothermic material accommodating portion 16. The pressed exothermic substance accommodating portion 16 moves downward, and the projection 21 erected on the bottom of the reaction vessel 9 breaks the sealing material 18b and supports the projection 19, so that the head of the projection 19 is formed by the cut 16a. 19a and the upper part of the other exothermic substance accommodating part 16 are separated. Accordingly, the upper part of the exothermic substance accommodating portion 16 other than the head portion 19 a is pushed downward of the reaction vessel 9.
That is, the sealing material 18b is broken and the exothermic substance 17 in the exothermic substance accommodating part 16 is pushed into the reaction inducing substance 20 at once, and the exothermic chemical reaction is started here.

The stopper 8 has a simple structure in which a ring having a cut portion 8a in a part is simply provided around the lower portion of the container body 4, and a finger or the like may be caught on the cut portion 8a for some reason to come off. However, since the container 1 with a heating function of the present invention is entirely covered with the film 22 including the lid 2, the container body 4, the reaction container 9, and the like, the stopper 8 is also covered by the film 22 with the lower part of the container body 4. It is fixed to. Therefore, unless the film 22 is removed from the heating function container 1 along the perforation 22b corresponding to the upper part of the stopper 8 of the film 22 for the purpose of initiating an exothermic chemical reaction, the stopper 8 is used by the film 22 to form the container body 4. It is held down and held at the bottom. Therefore, the malfunction that the stopper 8 is carelessly removed from the lower part of the container body 4 and the exothermic chemical reaction is started does not occur.
In addition, since a frictional force is generated between the film 22 and the container body 4 or the reaction container 9, the reaction container 9 is prevented from moving downward by sliding or rotating. There is no malfunction. In addition, since the container main body 4 is provided with the uneven flow path 6 and the anti-slip 7, the frictional force with the film 22 is exerted more strongly.
Further, when the film 22 is made transparent, a product display label inserted between the lid 2 and the container containing the object to be heated, a product advertisement affixed to the side surface of the container body 4, and a product handling method display It can be set as the structure which can see a label etc. from the outside in the state which covered the film 22 in the container 1 with a heating function.
In FIG. 2, the film 22 is provided only on the peripheral side surface of the container 1 with a heating function. However, the film 22 is also provided on the bottom surface of the sealing material 13 and / or the reaction container 9 of the container 11 for heating. It is good also as a structure which covers not only the side surface of the container 1 with a function but the upper surface, a bottom face, or the container 1 with a heating function. In such a structure, it is possible to further prevent the entry of dust and the like from the outside and further improve the sanitary condition during transportation and distribution of the container 1 with a heating function.
In addition, as described in paragraph 0031, when a product label or the like is inserted between the lid 2 and the container 11 containing the object to be heated, the label is better on the sealing material 13 by a film covering the upper surface. Can be held. In the present embodiment, the film 22 is preferably a plastic material that shrinks when heated, but it may be made of paper or other material as long as it is covered over the entire container 1 with a heating function. The material is not limited.

The bottom portion 14b has a concave shape so that when the reaction vessel 9 is screwed into the vessel main body 4, the exothermic substance accommodating portion 16 provided on the upper portion of the reaction vessel 9 can be pressed. The connecting portion 14c has a convex shape. Further, the pressing member 14 is formed with a plurality of radial holes 15 as shown in FIG. 3A so that the heating steam generated by the exothermic chemical reaction between the exothermic substance 17 and the reaction inducing substance 20 can flow into the upper portion of the container body 4. It has a structured.

  The shape of the pressing member 14 is not limited to the shape shown in FIGS. 2 and 3. For example, the container 11 can be placed on the upper portion like a structure in which a plurality of protrusions are connected and provided circumferentially. Any structure may be used as long as a protrusion is formed in the lower portion and the heat-generating substance accommodating portion 16 can be pressed downward by the protrusion.

Further, as shown in FIG. 3B, the protrusion 21 provided at the bottom of the reaction vessel 9 is formed in a cross-shaped cross section, and generates heat when the exothermic substance accommodating portion 16 is pushed down by the pressing member 14. The sealing material 18b provided in the opening of the substance containing portion 16 is easily broken.
Further, as shown in FIG. 3C, the protrusion 19 provided on the upper portion of the exothermic substance accommodating portion 16 is supported by the protrusion 21, and the protrusion 19 is separated from the upper surface of the exothermic substance accommodating portion 16. 21 is provided at the same position and shape as 21.

Here, the usage method of the container with a heating function of this invention is demonstrated using FIG.2 and FIG.4. FIG. 4 is a longitudinal cross-sectional view showing a state where the exothermic substance and the reaction inducer are reacted to heat the object to be heated in the container with a heating function according to the first embodiment of the present invention. 4, parts that are the same as those illustrated in FIGS. 1 to 3 are given the same reference numerals, and descriptions thereof will be omitted.
When the object to be heated 12 in the container main body 4 is heated using the container 1 with a heating function, first, the film 22 covering the reaction container 9 and the stopper 8 is removed along the perforation 22b, and further the stopper 8 is removed from the reaction vessel 9. Then, the reaction vessel 9 is screwed in the direction indicated by the arrow B in FIG. As a result, the pressing member 14 at the bottom of the container body 4 moves in the direction of the arrow C to break the sealing material 18a, and the upper part of the exothermic substance containing part 16 accommodated in the upper part of the reaction container 9 is moved to the arrow C. Press in the direction. As a result, the exothermic material accommodating portion 16 moves in the direction of arrow C, the sealing material 18b provided on the lower surface of the exothermic material accommodating portion 16 abuts on the protrusion 21, and further moves so that the sealing material 18b protrudes. Break through by 21. At this time, the exothermic substance 17 accommodated in the exothermic substance accommodating part 16 is mixed at once into the reaction inducing substance 20 accommodated in the lower part of the reaction vessel 9, and an exothermic chemical reaction by the exothermic substance 17 and the reaction inducing substance 20 is performed. Is started and high-temperature steam is generated.

Thereafter, when the exothermic material accommodating portion 16 is moved, the protrusion 19 comes into contact with the protrusion 21, but when the exothermic material accommodating portion 16 is further moved, the head 19a of the protrusion 19 and the upper portion of the exothermic substance accommodating portion 16 are divided by the notch 16a, as shown in FIG. Only the projection 19 remains supported on the projection 21.
Then, the high-temperature heating steam generated as shown in FIG. 4 is sent to the container body 4 from the communication hole 16b formed between the protrusion 19 and the heat-generating substance accommodating portion 16, and is further provided on the pressing member 14. It is discharged from the communication hole 5 through the gap 15 formed by the side surface of the container 11 and the inner side surface of the container body 4 through the hole 15. At this time, since the heat of the steam generated by the exothermic chemical reaction is conducted from the container 11 to the object to be heated 12, the object to be heated 12 in the container 11 is heated.
When the heated object 12 has been heated and the heated object 12 is to be drunk, the film 22 in the lid 2 part is removed along the perforation 22a of the film 22, and then the lid 2 is removed from the container body 4 and the container 11 is removed. The sealing material 13 is removed, and the lid 2 is attached to the container body 4 again. In such a state, when the heated object 12 accommodated in the container 11 is drunk, the container 11 is fixed on the pressing member 14 so that the container 11 is not detached from the container body 4 and falls to the drinker side. . Therefore, it can be consumed easily and safely.
Moreover, since it drinks in the state which mounted | wore the lid | cover 2, the upper end part of the outer peripheral part of the lid | cover 2 which contact | abuts a drinker's lip, or the inner peripheral part of the location cut out circularly is a better state by chamfering Can be drunk in.
In addition, in this Embodiment, since the sealing material 13 of the container 11 was shown as the structure hold | suppressed by the lid | cover 2, in order to drink the to-be-heated material 12, the lid | cover 2 is first removed once and the sealing material 13 is peeled off. Although it is necessary to make the diameter of the sealing material 13 smaller than the inner diameter of the portion of the lid 2 cut into a circle, the lid 2 does not have to be removed when the sealing material 13 is peeled off.

  From the above, in the present invention, as in Patent Documents 1 to 3, the reaction-inducing substance is not added to the exothermic substance to cause an exothermic chemical reaction, but the exothermic substance 17 is added to the reaction-inducing substance 20 all at once. By adopting a structure that causes a reaction, the exothermic chemical reaction can be completed in a short time because the area where the exothermic substance 17 and the reaction inducing substance 20 are in contact with each other is large. That is, the article to be heated 12 can be heated in a short time. In addition, since the exothermic substance 17 and the reaction inducing substance 20 are reliably mixed, the exothermic chemical reaction does not end unreacted. Further, unlike Patent Document 1 to Patent Document 3 in which heat is released from the reaction chamber where an exothermic chemical reaction occurs to the outside and the object to be heated is heated from the inside, a container in which the object to be heated 12 is accommodated. Since the heating steam moves outside the body 11 and heats the article 12 to be heated from the outside, the steam is not released without heating the article 12 to be heated, and efficiently from the entire outside of the container 11. It has a heatable structure and can heat the article to be heated 12 in a shorter time. Moreover, also in the point which can heat the to-be-heated material 12 in the state which made the pouring spout of the container 11, ie, the lid | cover 2 side of the container main body 4 upward, like patent document 1 thru | or patent document 3. There is an effect that it is not necessary to perform the operation of inverting the container body many times. An arrow D in FIG. 4 indicates the moving direction of the heating steam.

  Further, since the film 22 is wound on the surface of the lid 2 and the container main body 4, the heated steam released from the communication hole 5 passes through the flow path 6 to the storage portion formed by the film 22 and the steam reservoir 4 a. It is a mechanism to be stored. As a result, the heated steam is not discharged to the outside so that the user of the heating function-equipped container 1 will not be burned, but the chilled steam may flow out to the outside or be taken when drinking. There is no effect.

  Furthermore, since the container 1 with a heating function according to the first embodiment of the present invention is provided so that the reaction vessel 9 can be detached from the vessel body 4, even when the exothermic chemical reaction is not completely completed. The reaction container 9 can be unscrewed from the container main body 4 to stop heating the article 12 to be heated. Thereby, it becomes possible to heat the to-be-heated material 12 with a favorite heating condition. In addition, the structure to be heated is not directly stored in the container body as in Patent Documents 1 to 3, but another container that is not integrally formed inside the container body 4, that is, the object to be heated in the container 11. 12 is accommodated, so that the object to be heated 12 is taken out of the container body 4 when the temperature of the object to be heated 12 reaches an appropriate temperature instead of unscrewing the reaction container 9. It is possible to heat various kinds of objects to be heated 12 by exchanging the container 11.

  Since the film 22 covering the container 1 with a heating function can be cut off by the perforations 22a and 22b, the perforation 22b is cut off and the exothermic chemical reaction generating operation is performed, or the perforation 22a is cut off and the inside of the container 11 is cut. Even while the object to be heated 12 is being drunk, the portion that is not cut off by the perforations 22a and 22b, that is, the central portion of the film 22 remains. Accordingly, as described above, if a label for product indication or a precautionary note for use is inserted between the film 22 and the container body 4, the label etc. can be used from before use to after use of the container 1 with heating function. Since it can be seen by the user, it is possible to maintain the advertising effect of the product, and it is possible to constantly check the usage precautions and contents.

FIG. 5 is a conceptual diagram showing a container with a heating function according to the second embodiment of the present invention. In FIG. 5, the same parts as those described in FIGS. 1 to 4 are denoted by the same reference numerals, and description of the configuration is omitted.
In the container 1 with a heating function shown in FIG. 5, instead of the pressing member 14 of the container 1 with a heating function shown in FIGS. 2 and 4, a heated object container mounting portion 14d and a pressing portion 14e having the same function are separately provided. It is provided independently at the bottom of the container body 4. As shown in FIG. 5, the heated object container mounting part 14d has a structure having a horizontal surface on which the container 11 containing the heated object 12 can be placed, and the pressing part 14e is the upper part of the sealing material 18a and the exothermic substance accommodating part 16. The heated steam generated in the reaction container 9 by the exothermic chemical reaction of the exothermic substance 17 and the reaction inducing substance 20 is applied to the heated object container mounting part 14d and the pressing part 14e. For example, a plurality of holes 15a and 15b are formed in a radial pattern as shown in FIG. 3 (a) so as to flow into the upper portion of the container body 4. Accordingly, the heating function-equipped container 1 of FIG. 5 has the same effect as the heating function-equipped container of the first embodiment shown in FIGS.
In the first embodiment, the container 11 is fixed to the pressing member 14 by the lid 2. However, in the present embodiment, the container 11 is fixed to the heated object container mounting portion 14d. Moreover, the effect regarding the lid | cover 2 in the case of drinking is as having demonstrated in 1st Embodiment.
Note that the shapes of the heated object container mounting portion 14d and the pressing portion 14e are not necessarily limited to the shapes shown in FIG. 5, and are a structure capable of mounting the container 11 and a structure capable of pressing the heating material container 16, and Any structure having a plurality of holes and capable of releasing heated steam generated in the reaction vessel 9 by an exothermic chemical reaction into the vessel body 4 may be used.

Finally, the heating property of the container with a heating function of the present invention was compared and examined using a conventional product and the container with a heating function according to the first embodiment of the present invention shown in FIGS.
The conventional product has substantially the same structure as the container with a heating function of Patent Document 1, that is, the container with a heating function shown in FIG. 6, and the reaction chamber 24 and the container body 23 are made of aluminum. On the other hand, the container main body 4 and the reaction container 9 of the container with a heating function of the present invention are made of plastic, and the container 11 containing an object to be heated is made of paper.
Under such conditions, each operation method, that is, in the conventional product, an operation of pressing the bottom of the container body with a finger, and in the present invention, an operation of screwing the reaction container 9 into the container body 4 is performed. Wake up and heated 180 ml of sake to be heated, and the liquid temperature was measured. The results are shown in Table 1. Note that quick lime and water are used as the exothermic substance and the reaction inducing substance, and in FIG. 6, the reaction inducing liquid 35 and the contents 33 correspond to the reaction inducing substance and the object to be heated. The room temperature at the time of measurement is 26.0 ° C.

  Looking at the change in temperature of the object to be heated after the start of the exothermic chemical reaction, in the present invention, the reaction time was 0 to 4 minutes despite the fact that the container containing the object to be heated was made of paper. It can be seen that the temperature of the object to be heated rises more rapidly than the conventional product using an aluminum container having high thermal conductivity as the container for the object to be heated. Unlike conventional products, this is a structure in which the exothermic substance is mixed with the reaction inducing substance at once in the present invention, and heating is performed by enclosing the container in which the object to be heated is contained with the heating steam from the outside rather than from the inside. It is because it is a structure to do. From this, it is understood that the present invention can complete the exothermic chemical reaction in a shorter time than the conventional product, that is, the object to be heated can be heated in a shorter time.

  Applicable to containers with a heating function that can heat the object to be heated to the desired heating condition in a short time, and heat sake, soup, coffee, tea, tea, etc. in places where there is no heating means such as a microwave oven or gas stand it can.
