Pocket Vapor Bulb Operates Like Flashlight
As handy as a fountain pen, an electric vaporizer that works like a flashlight has been designed as a “pocket relief” for colds. In the head of the tiny metal case is a special bulb with two openings. A few drops of a nasal inhalant are inserted from the side. When the thumb switch is pressed, the “flashlight” batteries generate heat in the filaments of the bulb and vaporize the liquid, which is then inhaled from the top of the bulb, acting on congested nasal passages.
