2. Description of the Related Art Conventionally, as a container with a heating function of this type, there is a container provided with a heating chamber in which a liquid reaction assistant and a heating agent are housed separately from each other, in a container body in which an object to be heated is housed.

[0003] The above-mentioned container with a heating function is operated by pressing a bottom cover to operate an operation body attached to the bottom cover, or by opening a heat generating chamber by inserting a pin through a through hole formed in the bottom cover. The liquid reaction aid and the exothermic agent housed in the heat generating chamber are released from the isolated state, and the liquid reaction aid is exposed to the exothermic agent, thereby generating heat in the heat generating chamber and heating the object to be heated. .

[0004]

However, in the above-mentioned conventional container with a heating function, when the release of the liquid reaction aid is not sufficient or is not appropriate, the liquid reaction aid is sufficiently exposed to the exothermic agent. Can not be performed, the heat generation of the heating chamber is insufficient, and as a result, the object to be heated is not sufficiently heated,
There was a problem of insufficient heating.

[0005] In addition, the above-mentioned conventional container with a heating function has a problem that it takes time to sufficiently bathe the exothermic agent with the liquid reaction aid, and as a result, it takes time to heat the object to be heated. I was

Accordingly, the present invention is to provide a method for heating an object to be heated by sufficiently immersing the liquid reaction aid in the exothermic agent and not requiring sufficient time to sufficiently immerse the liquid reaction assistant in the exothermic agent. The object of the present invention is to provide a container with a heating function in which the heating of the object to be heated is sufficiently performed and the object to be heated does not require much time.

[0007]

Therefore, the container with a heating function of the present invention stores the liquid reaction assistant 1 and the exothermic agent 2 in isolation, and releases the liquid reaction assistant 1 simultaneously with the release operation to generate heat. The heating chamber 3 which can be exposed to the agent 2 is

Is provided on the side of the bottom lid 5a in the container body 5 containing the object 4 to be heated.

The liquid reaction aid 1 is stored in an inner container 6 provided on the side of the opening 3 a in the heat generating chamber 3, and the heat generating agent 2 is stored in the heat generating chamber 3. When the exothermic agent 2 is quicklime (CaO), water or a mixture of water and a preservative or antifreeze is used as the exothermic agent 2. Is used.

The object to be heated 4 is usually various kinds of foods and drinks such as sake, coffee, soup, curry and the like, but is not necessarily limited to foods and drinks.

The container body 5 is made of paper, synthetic resin, metal or other material, and the bottom cover 5a is deformable. The operating body 7 is pressed so that the operating body 7 can be pressed from outside the container body 5. One end of 7 is in contact with the inner bottom of the bottom lid 5a, and lid opening means 8 is attached to the upper lid 5b.

The inner container 6 seals the opening 6a with a film-like member 9 made of a material that can be broken by the operating body 7, and has a portion corresponding to a through hole 10 provided in the bottom lid 5a of the container body 5. Is provided with a projection 11.

The operating body 7 projects from the center of the bottom 6b of the inner container 6, and has a breaking member 12 at the tip.

Further, the container with a heating function according to the present invention is different from the embodiment shown in FIG. 4 in that the operating body 7 is protruded from the center of the bottom 6b of the inner container 6 via the thin film portion 13. At the same time, a cylindrical body 14 surrounding the operation body 7 is provided on the bottom 6b toward the inside of the inner container 6.

FIG. 7 shows a container with a heating function according to the present invention.
As in the embodiment shown in FIG. 7, the pin 16 is mounted at an appropriate place such as a protective lid 15 removably fitted to the end of the bottom lid 5a of the container body 5. A pin insertion space 7a is formed in the operation body 7, and the through hole 10 is provided at the center of the bottom cover 5a of the container body 5, and the through hole 10 and the pin insertion space 7a are formed. And a seal 17 that seals the through hole 10 is attached to the bottom lid 5 a of the container body 5. In this embodiment, the bottom lid 5a of the container body 5 does not need to be deformable.

The set value of the reduced pressure in the heat generating chamber 3 can be maintained even when the container with the heating function is left standing for several minutes after the heating operation of the container with the heating function of the present invention. Was set in consideration of the result of the liquid leak test as described below so that the gas does not leak from the through hole 10. [Liquid Leak Test] (1) Test Method Set the initial temperature of the object to be heated in various ways, set the decompression value of the heating chamber in various ways, and determine the amount of liquid leakage of the liquid reaction aid when heating the vessel with a heating function. Samples were taken with a spoid and measured. (2) Test results Table 1 shows the leakage amount of the liquid reaction aid.

[0021]

[Table 1]

From the test results shown in Table 1, the set value of the reduced pressure in the heating chamber 3 of the container with a heating function of the present invention is
No leakage at all regardless of initial temperature
cmHg or more.

The procedure for heating the above-structured container with a heating function of the present invention will now be described in detail.

First, the container main body 5 is repeatedly turned from the state shown in FIGS. 1, 4 and 7, and the bottom cover 5a is turned upward as shown in FIGS. 2, 5 and 8. Then, the release operation of the heat generating chamber 3 is performed as follows.

In the apparatus shown in FIG. 2, when the central portion of the bottom cover 5a is pressed and depressed by a finger, the bottom cover 5a is deformed as shown in FIG. Protrusions 11 provided at appropriate places in 6b expand the through holes 10. 8, when the pin 16 is inserted into the seal 17 of the bottom cover 5a, as shown in FIG. 9, the through hole 10 is opened and the pin 16 is connected to the break member 12 of the operating body 7 as shown in FIG.
Hit. Simultaneously with the above operation, the breaking member 12 is pressed against the film member 9 and the film member 9 is pierced.

Then, as shown in FIGS. 3, 6, and 9, the heat generating chamber 3 is released. When the inside of the heat generating chamber 3 returns from the reduced pressure state to the normal pressure state, the heat generating chamber 3 is released. The liquid reaction aid 1 is drawn into the exothermic agent 2 side of the heat generating chamber 3 together with the air that enters the inside, and the liquid reaction aid 1 is instantaneously immersed in the exothermic agent 2, and the exothermic agent 2 starts an exothermic reaction.

Simultaneously or several seconds after the start of the exothermic reaction, the container body 5 is returned from the repeated state to the original state, and is left standing for a few minutes in this state, so that the inside of the container body 5 can be heated. The object 4 is heated.

In the above operation procedure, in the container with a heating function of the present invention, as shown by the arrow in FIG. Since the liquid reaction aid 1 is drawn into the second side, the liquid reaction aid 1 does not leak from the through-hole 10. But,
In the conventional container with a heating function, since the inside of the heat generating chamber 3 is at normal pressure, the liquid reaction assistant 1 is pushed back by the air in the heat generating chamber 3 as shown by an arrow in FIG. The liquid reaction aid 1 may leak from the through hole 10.

Further, in the above operation procedure, the force of pressing the central portion of the bottom cover 5a with a finger is weak,
If the force of inserting the pin 16 into the seal 17 is weak, the film-like member 9 may be slightly broken and the liquid reaction aid 1 may remain in the inner container 6. Due to the effect, the liquid reaction aid 1 is hardly left in the inner container 6 because it is drawn into the heat generating chamber 3 and is instantaneously released.

In the container with a heating function of the present invention, the inside of the heat generating chamber 3 can be brought into a reduced pressure state, for example, by the following method.

First, as shown in FIG.
Then, the exothermic agent 2 is introduced into the exothermic chamber 3 in which the sealing agent 20 is held around the upper end and the inner container 6 is positioned above the exothermic chamber 3. Then, as shown in FIG. 13, a part of the air in the heat generating chamber 3 is drawn out from the gap between the periphery of the upper end of the heat generating chamber 3 and the flange 6 c of the inner container 6 by the vacuum pump 21, and as shown in FIG. 14. Thus, the inner container 6 is pressed against the heat generating chamber 3 by the press 22. Then, as shown in FIG. 15, the flange portion 6c of the inner container 6 comes into close contact with the periphery of the upper end of the heat generating chamber 3, and the pressure inside the heat generating chamber 3 can be reduced.

Further, in order to make the inside of the heat generating chamber 3 in a reduced pressure state, in addition to the above-described method, a deoxidizer is mixed into the heat generating chamber 3 together with the heat generating agent 2 or the inner container 6 is incorporated in the heat generating chamber 3. It can be carried out by an appropriate method, for example, by setting the working environment temperature of a process higher than the working environment temperature of another process.

Next, in order to compare the degree of temperature rise of the objects to be heated in the container body of the container with a heating function of the present invention and the conventional container with a heating function, the following temperature rise test was performed. [Temperature rise test] (1) Test method In the heating operation of a container with a heating function, when (A) the container body is returned to the original state from the state in which the container body is repeatedly turned over at the same time as the start of the exothermic reaction, (B) the exothermic reaction occurs. When the container body is returned to the original state from 5 times after the start, (C) after the exothermic reaction starts when the pierced state of the membrane member is incomplete. After 5 seconds, when the container body was returned from the repeated state to the original state, the temperature of the object to be heated was measured after a standing time of 1 to 8 minutes. (2) Test Results Tables 2 and 3 show the temperatures of the objects to be heated in the container bodies of the container with a heating function of the present invention and the conventional container with a heating function for the cases (A) to (C).

[0034]

[Table 2]

[0035]

[Table 3]

From the test results shown in Tables 2 and 3, in the container with a heating function of the present invention, in any of the cases (A) to (C), the temperature of the object to be heated was sufficiently increased. In the case of the conventional container with a heating function, in the case of (A), the temperature of the object to be heated did not rise sufficiently. This is because, in the conventional container with a heating function, when the inner container was taken out after measuring the temperature of the object to be heated, the liquid reaction assistant remained in the inner container, so the heat generation in the heat generating chamber was insufficient. It is.

[0037]

The container with a heating function according to the present invention is constructed as described above, and comprises a liquid reaction aid 1 and a heating agent 2.
And a liquid reaction aid 1
It is not necessary for the heating agent 2 to be sufficiently immersed in the heating agent 2, so that the object to be heated 4 is sufficiently heated, and the object to be heated 4 does not require much time.
