で、不用意にその区域に人が立ち入ると危険である。2. Description of the Related Art When a gas fire extinguisher is used to radiate a fire-extinguishing gas to a fire-generating area, the area is hermetically sealed and the fire-extinguishing gas is radiated. Therefore, not only during the fire extinguishing but also after the fire extinguishing, the area is filled with the fire extinguishing gas and the dangerous gas due to the fire, and it is dangerous for a person to enter the area carelessly.

災対象区域に放射される。In FIG. 2, reference numeral 1 denotes a gas container containing a fire extinguishing gas, and the fire extinguishing gas may be CO 2 , N 2 or the like. The nozzle 3 of the pipe 2 is in a fire target area, and gas is emitted from the nozzle 3 by the operation of the starter 4. The gas container 1 contains odorous substances together with gas. Therefore, this odorous substance is emitted from the nozzle 3 to the fire target area together with the fire extinguishing gas.

た。In the conventional gas-type fire extinguishing apparatus of this kind, the odorous substance is contained in the gas container 1 together with the extinguishing gas.
Since it is housed inside, there is a problem that the internal structure of the gas container 1 becomes complicated and expensive in order to prevent the odorous substance from chemically reacting with the fire extinguishing gas.

FIG. 1 is a vertical side view, and the same or corresponding parts as those of the conventional one are designated by the same reference numerals and the description thereof will be omitted. In the figure, 5 is a container valve attached to the gas container 1, which has a valve body 6 that opens and closes by the operation of the starter 4, and has a valve inlet 7 leading to the gas container 1 and a valve outlet 8 leading to the pipe 2. Have Reference numeral 9 denotes a mounting screw hole that is recessed in the head of the container valve 5, and communicates with the container valve 5 through a communication port 10. Reference numeral 11 denotes an odor container containing an odor substance 11a, which is screwed into the screw hole 9 by the protruding screw portion 12. Reference numeral 13 is a gas inlet of the odor container 11, which is a check valve 13a.
have. The odorous substance discharge port 14 of the odorous container 11 has a check valve 14a. Reference numeral 15 denotes a sealing lid which covers the odor substance filling port of the odor container 11.

物質１１ａが混入して放出ガスに臭いを付ける。Now, when the odor container 11 is attached to the screw hole 9 of the container valve 5 and set, the inside of the odor container 11 has the same pressure as the inside of the container valve 5, so the sealing plate 16 of the container valve 5 is broken and the valve is opened. Body 6
When the fire extinguishing gas is released from the gas container 1 through the valve inlet 7 and the valve outlet 8, the odorous substance 11a is mixed with the emitted gas to give the emitted gas an odor.
【００１０】このように臭い物質１１ａは臭い容器１１
