Abstract

PURPOSE: To reduce damage due to a fire to valuables by forming the walls of a container which can be airtight-sealed with a lid and made with a compounded layer comprising a metal material layer and a nonmetal, heat resistant, heat insulating material. CONSTITUTION: This container storing valuables is a rectangular container provided with a lid, its outer wall is formed with a metal material layer made of a metal material having a certain heat resisting temperature, and the inner surface of the metal material layer 1 is covered with a nonmetal, heat resistant, heat insulating material 2 adhered by an adhesive. Or this kind of container for storing valuables can be used as a set with a metal case having one, two or more lids and the valuables are stored in the metal case. When fire occurs, the rate of temperature rise in the container can be restricted even if the flame hits this container thereby restricting the oxidizing reaction between the valuables and oxygen inside the case.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention is applicable to securities, works of art,
A storage container for stamps, diplomas, qualification certificates, seals, floppy disks with data recorded, and other valuables that are easily burned or damaged by heat to reduce damage in the event of a fire. Regarding

[0002]

2. Description of the Related Art Conventionally, valuables are stored in containers made of materials such as paper, wood, cloth, and plastics that are easily flammable, flammable or weak to heat, or metal materials that easily transfer heat, such as steel. ing.

[0003]

When a container made of a material such as wood or paper comes into contact with a flame when a fire occurs, it immediately burns, and the flame propagates quickly to the inside of the container. Will be in contact with. When a valuable item that burns or is easily damaged by heat comes into contact with a flame, it will be instantly burned or damaged.
A container made of a metal material that easily transfers heat, such as steel,
Although the container itself does not burn when it comes into contact with flames, there is a great possibility that valuables in the container will be damaged due to causes such as a rapid rise in temperature inside the container. The present invention aims to reduce the possibility of damage to such valuables due to fire.

[0004]

In order to achieve the above object, the present invention does not use flammable or combustible materials. In order to prevent the valuables stored in the container from coming into contact with external flames or hot air, the container is provided with a closed structure provided with a lid or a door. In order to reduce the amount of air inside the container as much as possible, it is desirable that the container volume be as small as possible depending on the volume and shape of the particular valuable.

In order to block the introduction of heat into the interior of the container from the external environment, the peripheral wall of the container is made to include a non-metal heat-resistant and heat-insulating material layer to form a valuables storage space surrounded by the non-metal heat-resistant and heat-insulating material layer. As the non-metal heat resistant heat insulating material, a lightweight fibrous plate material having excellent heat resistance, heat insulating property, and chemical stability, for example,
Ceramic fibers (glassy), ceramic fibers (polycrystalline), etc. are desirable. The thickness of the heat insulation layer is 1
It is desirable that the thickness be at least cm, but the thicker the better the heat insulating effect.

A non-metal heat-resistant insulating material is attached to the surface of the metal thin plate, and the metal thin plate constitutes the basic shape of the container. As the thin metal plate, a metal material having a certain heat resistance strength, such as stainless steel, iron, aluminum, titanium, or copper, is desirable.

Many non-metallic heat resistant insulations are very low density porous materials and contain air. There is also a non-metal heat-resistant heat insulating material which is surface-treated by spraying a thermosetting resin such as phenol resin. With these materials,
The hot air generated by heating or the vaporized organic matter diffuses into the container and may come into contact with the valuables, causing damage such as partial combustion or carbonization of the valuables.
If the non-metal heat-resistant heat insulating material avoids direct contact with valuables, and it is sandwiched between two layers of thin metal material,
The damage of valuables can be further reduced.

[0008]

In order for combustion to occur, the presence of flammable substances, oxygen and ignition sources (thermal energy) is necessary. This is called the three elements of combustion. The burning of valuables due to a fire is due to the oxidation reaction in the mixed system of valuables and air. The present invention can also adopt a closed structure to avoid contact between valuables and outside air. Also, the thermal conductivity of many non-metal heat-resistant heat insulating materials is less than one thousandth of the thermal conductivity of ordinary metals. The present invention has a heat insulating ability of 1 mm.
Compared with the case of a container made only of a thin metal plate,
10,000 times or more. That is, in the present invention, it is to remove as much as possible two elements of oxygen and an ignition source among the three elements of combustion. Even when the present invention hits a flame when a fire occurs, it is possible to suppress the rate of rise in the temperature inside the container and suppress the oxidation reaction between the valuables therein and oxygen.

Embodiments of the present invention will be described with reference to the drawings.

A first embodiment of the present invention will be described with reference to FIG. The container for storing valuables of the first embodiment is a rectangular container provided with a lid, the outer wall of which is formed of the metal material layer 1,
The non-metal heat-resistant and heat-insulating material layer 2 is attached to the inner surface of the metal material layer 1 with a heat-resistant adhesive to form the inner wall of the container.

A second embodiment of the present invention will be described with reference to FIG. The container for storing valuables of the second embodiment is a set of the container for storing valuables of the first embodiment and a metal case 3 provided with one or more lids. Valuables are stored in the metal case 3.

[0012]

[Effects of the Invention] Valuables such as securities, works of art, stamps, diplomas, qualification certificates, seals, and floppy disks with data recorded are not subject to ordinary fire mutual aid, and many In some cases, once these valuables are damaged by heat, they cannot be remanufactured. By the way,
Of course, the loss of these valuables due to a fire is considerable, but intangible losses that are difficult to evaluate financially are usually very large. When these valuables are stored using the valuables storage container made according to the present invention, there is an effect of significantly reducing damage due to fire.
