Description

[Detailed description of the invention] This invention is a container for instantly heating or cooling various foods and drinks, and more specifically, a container that causes a thermal change by mixing the contents and heating or cooling the contents. The present invention relates to a storage device for a substance that is incorporated into a container, in which the content is heated or cooled by a thermal change of the substance and a heat exchange of the content.

The substances to be incorporated into the container are a reactant that generates heat or cold on one side, and a reaction inducer on the other, which are mixed by operating a mixing means provided in the container. Examples of the reactant include quicklime, caustic soda, ammonium nitrate, Various salts can be used, and the easiest reaction inducer for the above is water, for example, and the reactant, the reaction inducer, and the contents are stored separately in a container, and the part that houses the reaction inducer is used. Mixing is performed by opening the container.

Containers such as those described above are extremely convenient as they allow easy consumption of soft or cold food even in places where there is no heat source or cooling means.

On the other hand, when heating the contents, when the heat exchange between the heat change of the substance and the contents is not sufficient, or when mixing substances without the contents, The pressure in the material storage space will become abnormally high, and if such a high pressure occurs, there will be a risk of explosion.

This invention was developed to prevent the occurrence of the above-mentioned dangers, and its purpose is to prevent the occurrence of dangers by smoothly guiding the pressure generated when mixing substances to the outside. In addition, it is an object of the present invention to provide a storage device in which a tank can be easily opened and substances can be mixed smoothly.

Next, the details of an embodiment of the present invention will be described below based on the accompanying drawings showing one embodiment of the present invention.

In the figure, 1 is the main body of the container, which is made of heat-resistant material, and whose interior is divided by a bottomed container-shaped partition wall 2 that extends downward from the upper edge opening. A storage chamber 3 for objects A and a substance storage chamber 4 are formed within a partition wall 2.

The opening at the bottom of the container 1 is sealed with a well-known openable lid, and the container 1 is not only an integral structure in the form of a can as shown in the figure, but also has a synthetic resin main body with a separate partition wall in a watertight manner. Of course, it is possible to attach it or to form it into a scale-like shape and structure.

A reactant B for generating heat or dust and a reaction inducer C are separately stored in the substance storage chamber 4 of the main body 1 of the container, and the reactant B is directly stored in the partition wall 2. , the reaction inducer C is stored in a storage device 5 fitted into the opening of the partition wall 2.

Roughly speaking, the storage device 5 includes a tank body 6 made of heat-resistant synthetic resin or the like, and an unsealing member 8 screwed onto a top plate 7 that closes an opening at the upper edge of the tank body 6.

The tank body 6 is formed into a hemispherical shape or the like to fit inside the partition wall 2, and has a flange 9 around the outer periphery of its upper end. Part 10 is polymerized.

An outlet 11 is formed at the lower end of the tank body 6.

This outlet 11 is closed in a watertight manner by stretching a thin piece 12 using aluminum foil or a synthetic resin sheet.

The thin piece 12 is fixed to the lower end surface of the tank body 6 by means such as heat sealing, and if aluminum foil is used, it is treated to be chemically resistant to the reactant B.

The top plate 7 has a disc shape that overlaps the flange 9 of the tank body 5 and forms a peripheral wall that rises from the outer periphery, and each molded part of the flange 9 and the container body 1 is fixed in a honey-like manner by heat sealing or adhesive. To prevent the reaction inducer C stored in the main body 6 from leaking.

A cylindrical body 13 that opens at the center of the top plate 7 and projects toward the inside of the tank body 6 is connected to the lower center of the top plate 7.

A female thread 14 is formed on the inner peripheral surface of the lower end of the cylindrical body 13, and
The lower end opening faces directly above the outlet 11 of the tank body 6, and the lower end opening of the cylindrical body 13 is also sealed watertight with a thin piece 15 made of aluminum foil or a synthetic resin sheet.

As shown in FIG. 2, the unsealing member 8 has a male screw 1 screwed into the female screw 14 on the outer periphery of the lower end of the shaft portion 16 that is inserted into the cylinder 13.

couple.

The shaft portion 16 is formed into a hollow shape with a passage 20 that ends midway in the axial direction from the lower end, and the lower edge of the shaft portion 16 has a broken portion 21 in the shape of a corrugated or thin cutting edge in order to break through the thin pieces 12 and 15 when screwed in. form.

The unsealing member 8 has an escape hole 22 that penetrates from the passage 20 to the outer peripheral surface in the middle of the tank body 6 in order to release the pressure generated inside the tank body 6.
and an axial slit 2 on the outer peripheral surface of the large diameter portion 18.
form 3.

By screwing the unsealing member 8 into the cylindrical body 13, an annular space 24 is formed between the cylindrical body 13 and the unsealing member 8, and the slit 2
A diffusion chamber 25 is formed at the upper end of the camera 3 between the camera 19 and the top plate.

The pressure generated within the tank body 6 is released through the passage 20 and the escape (L2
2. From the cavity 24, the slit 23, and the diffusion chamber 25, the air passes through wide and narrow areas alternately, and the pressure is effectively buffered by this alternate passage.

In addition, 26 in the figure is a reinforcing rib given to the top plate 7, and the tank body 6, the top plate 7, and the cylindrical part 13 may be integrally formed by blow molding separately from the illustration. This makes it possible to reduce manufacturing costs.

Further, the outer circumferential surface of the male threaded portion 17 of the unsealing member 8 is provided with an axially or inclined cut groove 27 as shown in FIG. If the passage 20 is closed and pressure gas is prevented from flowing out when the seal is opened by screwing the opening member 8, the pressure gas is released to the outside through the cut grooves 27. This is what I did.

The present invention has the structure as described above, and its use will now be explained for heating the contents A.

With the container main body 1 erected as shown in FIG. 1, the opening member 8 is rotated in the screwing direction at a portion 19 thereof.

The unsealing member 8 enters the tank body 6 by screwing,
The crushing part 21 formed at the lower end first breaks through the thin piece 15 stretched over the lower end of the cylindrical body 13, and then through the thin piece 12 stretched over the outlet 11 of the tank body 6.

Due to this break-through, the reaction inducer C stored in the tank body 6 flows out from the break into the storage chamber 4 of the partition wall 2 and mixes with the reactant B filled in the lower part of the partition wall 2.

The reaction inducer C and the reactant B react by mixing, and the partition wall 2
The content A stored in the main body 1 of the container is heated to a desired state by heat exchange via the partition wall 2.
At the same time as heating is completed, the lid of the container main body 1 is opened and the contents A are taken out and served for eating and drinking.

Therefore, when the reaction inducer C and the reactant B react, the storage chamber 4
When high-pressure gas is generated inside, this high-pressure gas is removed from the opening member 8.
from the passage 20 of the cavity 2 through the escape hole 22 or the cut groove 27.
4. It passes through the slit 23 and the diffusion chamber 25 and is released into the atmosphere as water vapor, which prevents the occurrence of an explosion due to abnormally high pressure and also muffles the sound at the time of release.

As described above, the present invention is a container whose contents are heated or cooled by temperature changes caused by mixing a reactant and a reaction inducer, and which is built into the substance storage chamber of the container and is opened into a hollow tank that stores one substance inside. The members are screwed together, and a passage is formed in this member to release the pressure generated inside the container to the outside when the tank is opened, so even if high pressure is generated inside the container during a reaction due to warming of the substance, this high pressure will be released to the outside. The safety of the container for heating or cooling the contents can be improved by mixing the separately stored substances.

In addition, the reactant and the reaction inducer can be mixed simply by rotating the opening member, making it easy to mix and eliminating the inconvenience of inadvertently opening the package due to the rotating operation. It has excellent effects such as:
