The lower box 3 is composed of a side plate 3a and a bottom plate 3b, and is formed to have a diameter substantially the same as the diameter of the upper box 2. Upper box 2 and lower box 3
Is formed by fixing a plate material cut into a predetermined shape by welding or the like. The dust input port 4 has a length L1 and a width L2 such that an A4 size document enters in the vertical direction. As a result, newspapers, magazines, and other papers can be efficiently collected in the collection box 1,
Further, it is possible to prevent an empty can or the like from being accidentally thrown into the collection box 1.

On the ceiling of the upper box 2, a fire extinguishing device 6
And a warning device 10 is provided. The fire extinguisher 6 is composed of a bag-shaped container 7 and a fire extinguishing agent 8 with which the inside thereof is filled, and is hung by a tension cord 14 at the center of the ceiling. The bag-shaped container 7 is made of polyethylene and is set so that the bag has a relatively small layer thickness and is not easily broken. Figure 7
As shown in, the joint portion 7a of the bag-shaped container 7 is heat-sealed and sealed after the extinguishing agent 8 is filled in the bag. As the material of the bag type container, if it is a flammable material, other than polyethylene,
It may be vinyl, paper, leather, cloth, rubber or the like.

As the fire extinguishing agent 8, for example, a powder having a non-catalytic action, such as ammonium phosphate and ammonium sulfate, is used. Moreover, you may use water, sand, etc. which have a cooling effect. The filling amount of the fire extinguishing agent 8 is preferably about the capacity of the bag-shaped container 7, but particularly when a powdery fire extinguishing agent is used, the powder is not compressed in the container.

As shown in FIGS. 3 to 6, the warning device 10 comprises a warning plate 12, a torsion spring 13, a tension cord 14 and guides 15 and 16. By switching the warning plate 12 from the fallen state shown by the solid line in FIG. 5 to the standing state shown by the chain double-dashed line in FIG. 5, the operating state of the fire extinguisher 6 is notified to an external person. On the surface of the warning plate 12, for example, characters such as "fire occurrence" are displayed. As shown in FIG. 6, the upper box 2
The support shaft pin 16 is fixed to the side surface of the recess 2c, and the base portion 12a of the warning plate 12 is rotatably inserted into the support shaft pin 16. A torsion spring 13 is attached between the warning plate 12 and the side surface of the recess 2c, and the warning plate 12 is rotatably biased from the fallen state to the standing state.
