Abstract
A vaporizer for air treatment and the like producing vapors which can be renewed to provide effective operation for an extended period of time. The vaporizer comprises an hourglass-shaped container having a pair of adjacent chambers communicating by means of a restrictive orifice. Each chamber has an opening in the end covered by a porous membrane. The container contains a supply of particulate fluid-like carrier material carrying a volatile vapor-producing treating material. A part of the treating agent is transferred by the carrier material to the membrane for producing air treating vapors by volatilization or evaporation of the treating agent. Inversion of the container, mixes and redistributes the treating agent among the carrier vehicle particles and exposes a freshly loaded vapor producing membrane.
Claims14
A renewable vaporizer for producing air treating vapors comprising a container having at least one opening therein, a supply of fluid-like carrier material carrying a vapor producing treating agent contained within said container;
- and a porous membrane covering said opening, said fluid-like material being in contact with said membrane to transfer a part of said treating agent thereto when said container is positioned in a first orientation, said membrane operating to bring a part at least of said transferred treating agent into contact with the outer surface of said membrane for producing air treating vapors.
