ABSTRACT:
A device having an open top container holding a quantity of a volatile paste like material within the interior of the container, which material is intermittently dispensed in vapor form to the ambient atmosphere. An electric circuit controlled motor is intermittently energized at predetermined time intervals to rotate a fan in the device for specific time periods to direct currents of air onto the exposed surface of the paste and transform the paste into vapor that is discharged outwardly from the container. A portion of the device is defined by apertured walls that surround the container, with the apertures of sufficiently small size that the container in the device is substantially concealed, and the apertures serving the further functions of permitting air to not only flow into the interior of the device through a first portion thereof but as the fan operates also forming the vapor from the paste material into a number of small streams thereof as the vapor discharges outwardly through a second portion of the apertures into the ambient atmosphere to mix therewith.
