Abstract
A simplified vaporizing dispenser features snap attachment of a base cap to an inverted container, positive "ON" and "OFF" adjustments for the respective activation and deactivation of the dispenser, the use of an absorbent sheet shaped in the form of the frustum of a cone with the narrow end inserted in an annular well for isolating the wetting area of the absorbent material from the vaporizing area and thereby enabling waving of the dispenser about in the air without spilling liquid, and an outer decorative sleeve that enables adjustment in the emitted vapor level.
