ABSTRACT:
A vapor generator for generating vapors from a vaporizable liquid concentrate such as a deodorant-fragrance concentrate and employable either with or without a fan dispenser. The vaporizable liquid is sealed within a receptacle having an openable top portion, such as a pull-top can, and a capillary action diaphragm is located under the top so as to be exposed when the top is opened. The vaporizable liquid is transported upwardly from the body of liquid to the diaphragm by capillary action membrane means extending from the top to the bottom of the receptacle, and then distributed by capillary action through the diaphragm and vaporized from the exposed surface thereof. A small pressure equalization port through the diaphragm equalizes the vapor pressure under the diaphragm to substantially atmospheric pressure so that such vapor pressure will not interfere with the capillary actions. The good vaporization rate control obtainable by this arrangement enables a combination of active and carrier ingredients to be used for the liquid which are substantially entirely vaporizable at rates corresponding to their proportions, for effective functioning of the vapor generator over a long operational life cycle.
