DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in more detail with reference to FIGS. 1, 3 and 5 are schematic perspective views showing an example of a disaster prevention article having an overheating / fire notification function of the present invention, and FIG. 2 is a sectional view of FIG. 1. FIG. 4 is a cross-sectional view of an example of a disaster prevention article having an overheating / fire notification function of the present invention for notifying an abnormality by sound.

As shown in FIG. 1, a disaster prevention article 1a having an overheating / fire notification function according to the present invention comprises a content 3a containing a substance generating at least one of odors and colors and a container for enclosing the same. 2a, said container 2a
Has a function of releasing or melting or tearing at least a part of the content 3a by heat and / or flame to diffuse or flow out the contents 3a, and by generating at least one of odors and colors, This is to notify the abnormality to the outside.

The container 2a only needs to be capable of being opened, melted or torn at least in part by heat or flame or heat and flame, and has a high sealing property to the contents 3a and does not react with the contents 3a. It is required that the material is a metal such as aluminum, gold, silver, copper, stainless steel, or a polymer compound such as polyethylene, nylon, polypropylene, polyester, polystyrene, polyethylene terephthalate, polyolefin, rubber, etc., alone or in combination. Used. Further, the shape may be a molded product such as a bottle shape, a box shape, a tubular shape, etc., but it is preferable that a sheet-shaped material or a film is formed by fusion or adhesion.
The method for manufacturing the container 2a can be performed by known bag making, packing, and molded body manufacturing techniques, and thus the description thereof is omitted.

In addition, the above-mentioned overheating and fire
The function of opening or melting or tearing at least a part of the container 2a by heat and / or flame to release or flow out the contents 3a to the outside is performed by bonding, which is a sealing portion of the container 2a made of a sheet-like material or a film. The heat-sealed portion may have that function. In these, the adhesive or fused portion is peeled off by heat or a rise in the pressure in the container 2a due to heat or a flame, and the contents 3a are diverged or flown out to the outside. Further, as another method, the same effect can be obtained by providing a part of the container 2a which is weakened mechanically or thermally, and in this case, particularly, in this case, the container 2a is heated or pressed by heat or pressure. It is easy to set the opening properly and the operation can be stabilized. The temperature at which the above-mentioned opening, melting, or tearing occurs is 80 ° C to 260 ° C, preferably 85 ° C to 1 ° C.
It is desirable to work at a temperature of 50 ° C. If the temperature is lower than 80 ° C., there is a problem that a malfunction occurs due to a summer temperature or heat storage of equipment and the like. If the temperature is higher than 260 ° C., the general wood-based material and the wire covering material are damaged before the notification function is activated. Is not preferred.

Substances that generate odors and colors include odors due to fragrances, colors of dyes, pigments, fluorescent paints, coloring agents, coloring agents, and the like. These contents 3a, 3b
When a part or all of the containers 2a and 2b are opened due to heat or an increase in internal pressure due to heat or a fire, the containers 2a and 2b are diverged or released or flow out to inform the surroundings of an abnormality by odor or color or odor and color. .

Examples of substances (fragrances) that generate an odor include acetyl-1,1,2,4,4,7-hexamethyl-tetrahydronaphthalene, acetylmethylcarbinol, ethylvanillin, isoeugenol acetate, eugenol acetate, and acetic acid. There are flavors such as ヂ methylbenzylcarbinyl, but not limited to these.

As the substance (dye) which generates color, for example, other known dyes such as an azo dye, an anthraquinone dye, an indigo dye, a phthalocyanine dye, a carbonyl dye, a quinone imine dye and a methine dye can be used. As pigments, lead white, titanium oxide, aureoline, cobalt green, cobalt blue, carbon black, ultramarine, graphite and other inorganic pigments and para red, benzidine yellow, indanthrone, phthalocyanine,
Various pigments such as dioxazine, anthraquinone-based, and azo-based organic pigments can be used. In addition, dyes,
Regardless of the type of pigment, various fluorescent paints, colorants, and color formers can be used.

[0017] The above-mentioned odor- or color-producing substance is preferably enclosed as a content in a container together with water, so that it is discharged or released to the outside of the container in the event of overheating or fire, thereby generating a odor or color. In addition, it can notify the surroundings of the abnormality and add the effect of suppressing heating and fire.

Further, a material and / or a substance having endothermic and / or heat resistant and / or digestible properties can be enclosed as contents together with these substances in a container.
Examples of the heat-absorbing and / or heat-resistant material and / or substance include water, gypsum, ettringite, metal hydroxide, or a thermally expandable material such as vermiculite and graphite, or rock wool, ceramic wool, and glass wool. And various inorganic materials such as perlite. In addition, as the digestive material and / or substance, water, calcium carbonate, halogenated hydrocarbon, carbon dioxide,
Inert gas and the like can be mentioned, but water is preferably used for a fire. As a result, it is possible to obtain an effect of notifying the surroundings of the occurrence of overheating or fire, and suppressing or reducing a disaster.

Further, the container enclosing these contents is:
As shown in FIG. 3, it may be provided continuously in a divided form.

FIG. 4 shows a container 2b for enclosing the contents 3b.
And a sound generating device (whistle) 5 by the connected gas flow
It is sectional drawing of the disaster prevention article 1c provided with. There is a method in which a part of the container 2 is provided with a sealing portion 4b made of a low melting point material such as paraffin or paraffin hydrocarbon.
Alternatively, the sealing portion 4b is opened or ruptured by a flame to release the contents 3b.

As the sealing portion 4b, a plug or valve made of a shape memory alloy or a thermoplastic resin may be used for a part of the container 2b or for the sound generating device (whistle) 5. In this case, a structure in which the stopper or the valve is opened by overheating or heating by fire is preferable.

In this embodiment, the sound generating device 5 is provided with a device that generates sound by a whistle or a gas flow connected to the sealing portion 4b. Of course, it is desirable that the sound emitted by the device has a characteristic in the waveform and / or frequency of the sound.

Examples of the substance that generates sound include a nonflammable gas or a solid or liquid that generates a nonflammable gas by heat, and more preferably a carbon dioxide gas or an inert gas. Further, the content can be mixed with a substance that generates odor or color.

With these configurations, the sealing portion 4b is opened by overheating or heating of a fire, and a sound is generated by discharging the non-combustible gas (gas) as the contents 3b. The fire can be reduced by the suffocation effect such as the above.

FIG. 5 is a perspective view showing a case where a heat insulating material and / or a fire-resistant material are combined with the disaster prevention article 1a. In the figure, reference numeral 6 denotes a heat insulating material and / or a refractory material, which is disposed on one side of a container 2a in which the contents 3a are enclosed, and is integrally laminated. Examples of the heat insulating material and / or the refractory material include inorganic fiber felts and / or mats such as rock wool, glass wool, and ceramic wool. In the event of a fire,
It notifies the occurrence of a fire and prevents the spread of the fire.
