ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a device which can be used to extinguish small fires. In particular, it relates to a device which is suitable for use in extinguishing small fires such those associated with the wick of a burning candle, without leaving residual smoke.
BACKGROUND OF THE INVENTION
It is known that many asthmatics and others who have lung diseases such as emphysema, have extreme difficulty breathing in a smoky environment. Even very dilute concentrations of smoke can cause asthmatics to have attacks which can be life threatening. For that reason, asthmatics tend not to burn candles for decorative purposes around the home and elsewhere, because when a burning candle is extinguished using conventional techniques, the wick of the candle will give off substantial quantities of smoke after the actual fire is extinguished. Often times, this residual smoke will trigger an asthma attack.
SUMMARY OF THE INVENTION
The present invention is specifically designed to enable small fires to be extinguished such as those associated with the wicks of candles, without leaving a residue of smoke after the fire is extinguished. Thus, there is provided a smokeless fire extinguishing device. The device has the shape of conventional tweezers, having opposing attachments positioned on the tips thereof which have inwardly facing wax inserts. When it is desired to extinguish the flame of a candle, the tips of the device are positioned on opposite sides of the burning wick of the candle, and then forced together. The wax inserts on the attachments on the tips come into contact with the wick of the candle, extinguishing the flame without there being a smoke residue.
