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.
