For this reason, if the garbage container should be set on fire, first of all, simple fire extinguishing tools such as a water bucket come into play, but they are often not prepared. In addition, gastrointestinal tracts are often expensive and rarely prepared, and even if they are provided, the storage location is not known at all times and it is often difficult to use them.

[0003] In the first place, an arson in a garbage container is not noticed immediately after it is made, but is noticed after it becomes large. In general, it is impossible to extinguish a fire simply after discovery.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a garbage container capable of automatically extinguishing a fire in an initial stage even if the garbage container is arsoned.

[0005] A means for this is a trash container having a ceiling above the garbage container, wherein a fire extinguishing material is provided on the inner side surface of the ceiling, and the fire extinguishing material is placed in the garbage container. It is a garbage container held in a holding material that is cut by being melted or burned by overheating due to fire.

It is preferable that the fire extinguishing material is composed of a liquid, and the fire extinguishing material is stored in a lower portion of the holding material so that air exists above the liquid level of the fire extinguishing material. .

Further, the fire extinguishing material may be composed of a powder.

[0008]

According to the above construction, even if the garbage container in the garbage container is ignited, the holding material on the ceiling located above the garbage can be melted or burned by the overheating of the fire caused by the arson. Can be Then, the holding material is cut and the fire extinguishing material inside flows out. The extinguished fire extinguishing material is applied to the fire breaching the holding material from above, performs cooling and air blocking, and extinguishes the fire.

As described above, the fire in the garbage container can be automatically extinguished at an early stage. Therefore,
No other fire extinguisher is required and the fire can be reliably extinguished before it grows. In addition, the configuration for that is provided with the fire extinguishing material stored in the holding material on the ceiling of the garbage container, so that the configuration is simple and the cost can be reduced.

When the ceiling of the garbage container is a detachable lid, the lid becomes heavier to some extent due to the presence of the fire extinguishing material. Even if you do not put it, it will not be removed by wind or cat mischief.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing the structure of a trash container 1. In the trash container 1, a lid 3 is detachably fitted to an upper surface of a main body 2 having a trash container 2a therein.

The cover 3 is provided with a fire extinguishing material 4 on the inner surface on the inner peripheral side of the outer peripheral portion 3a facing the opening edge 2b of the main body 2.
It is held and provided in the holding material 5. The fire extinguishing material 4 held by the holding material 5 is a fluid, for example, water or another fire extinguishing agent.

The holding material 5 is for letting out the fire extinguishing material 4 when a fire starts, and is made of a flammable and thin synthetic resin. In this structure, the fire extinguishing material 4 is stored in the lower part of the holding material 5 so that air exists above the liquid level of the fire extinguishing material 4.

That is, as shown in FIG. 2, the shape of the cover 3 is formed in a circular shape in a plan view so as to correspond to the shape of the cover 3.
A plurality of concave grooves 5b are arranged in parallel at regular intervals from the position slightly lower than the outer peripheral edge 5a to the inner peripheral side. I have. A portion connecting these concave grooves 5b to the inner peripheral side of the outer peripheral edge is a connecting portion 5c.

On the upper surface of the lid 3, an injection port 3b for injecting the fire extinguishing material 4 into the holding material 5 is formed. The inlet 3b has a detachable cap 6 having airtightness. This prevents the internal fire extinguishing material 4 from leaking when the cover 3 is opened and closed. When the fire extinguishing material 4 is injected, the fire extinguishing material 4 is injected until the upper surface of the concave portion 5b is completely cut off. This is because, if more than this, the holding material 5 is not broken by the fire in the dust container 2a.

In the trash container 1 configured as described above, fire or ignited material is thrown into the trash container 2a in the main body 2,
In the case of spontaneous ignition in the garbage container 2a,
The connecting portion 5c of the holding member 5 of the lid 3 located above the fire 7 is burned by the overheating of the fire 7. Then, as shown in FIG. 3, the connecting portion 5c of the holding material 5 is cut, and the fire extinguishing material 4 inside flows out. The extinguished fire extinguishing material 4 is applied from above to the fire 7 that has broken the holding material 5, performs cooling and shuts off the air, and extinguishes the fire.

As described above, the fire extinguishing operation can be automatically performed on the fire 7 in the garbage container 2a at an early stage. Therefore, no other fire extinguisher is required, and the fire can be reliably extinguished before it becomes large. Moreover, since the plurality of concave grooves 5b are formed, the fire suppression action can be reliably performed not only at the center of the dust container 2a but also at the end as shown in the figure. In the case where the opening area of the garbage container 2a is small, instead of forming a plurality of concave grooves 5b and holding the fire extinguishing material 4 therein, the fire The fire extinguishing material 4 held in the concave groove 5b may be configured to flow out at once.

Further, since the structure for this purpose is provided with the fire extinguishing material 4 housed in the holding member 5 in the lid 3 of the garbage container 1, the structure is simple and the cost can be kept low.

Further, since the lid 3 becomes heavier to some extent due to the presence of the fire extinguishing material 4, the lid 3 is removed by the wind or the mischief of a cat without placing a weight on the lid 3 as in the prior art. Never.
