Intermittent time controlled vapor dispensing device

In combination with an open top container holding a quantity of a paste-like material that is volatile and vaporizes when a current of air at ambient temperature is discharged thereon, a device for intermittently discharging a current of air onto the exposed surface of said material for a predetermined period of time at spaced time intervals of substantial duration to transform a portion of said material into vapor that is discharged outwardly from said device as a plurality of streams thereof, said device including:

• a. a housing assembly that includes a first opaque portion defined by an elongate rigid backwall that has a top member and bottom member projecting forwardly therefrom, and a second opaque portion that includes a vertical front wall and two laterally spaced side walls that have a plurality of small apertures therein, said second opaque portion being pivotally mounted to said first opaque portion to be pivotable between a first and a second position, when said second opaque portion is in a first position it defines a confined space within the interior of said housing, a first portion of said apertures serving to permit the flow of air into said confined space and a second portion of said apertures permitting the concurrent discharge of said air outwardly therethrough from said confined space in a substantially horizontal direction and substantial velocity to the ambient atmosphere, with said apertures of sufficiently small size as to substantially obstruct viewing the interior of said housing from the exterior thereof;
• b. first means for removably supporting said container in said confined space adjacent said bottom member;
• c. a bladed fan in said confined space disposed above said container;
• d. an electric motor that has a drive shaft to which said fan is secured;
• e. second means for holding said motor, drive shaft and fan in a fixed position in said confined space in said housing;
• f. a source of electricity;
• and
• g. and interval timer operable intermittently at spaced time intervals of substantial duration to send electric current from said source to said motor to operate the latter for predetermined periods of time, with said fan as it is rotated by said motor, drawing air into said confined space through said first portion of apertures and discharging a current of air at substantial velocity onto the exposed surface of said material in said container to transform said material into vapor that with the air is discharged through said second portion of apertures as a plurality of said streams.
