Constant-rate volatile material dispensing device

An aroma dispensing device for delivering volatile materials at a constant rate for atmospheric dispersal, comprising:

• a reservoir comprising a top, a bottom wall, and at least one reservoir side wall, said reservoir having an interior surface defining a cavity and defining an outlet port;
• a lower housing comprising at least one lower housing side wall and a base, said base having an interior surface, said at least one lower housing side wall configured with one or more vents configured to allow air circulation and configured with two vertical slots;
• at least one volatile material contained in said cavity;
• a tube having an upper section coupled to said outlet port and having a lower section extending downward into said lower housing, said tube providing fluid communication between said cavity and said lower housing, said tube configured to allow passage of said at least one volatile material;
• a valve coupled to said tube and configured to control the flow of the said at least one volatile material through said tube;
• a valve adjustment mechanism disposed in one of said two vertical slots of said at least one lower housing side wall being moveable between at least a first position and a second position;
• a pad attached to said interior surface of said base, said pad configured to receive said at least one volatile material;
• and
• a tear-off tab disposed in one of said two vertical slots of said at least one lower housing side wall, said tear-off tab extending from said lower section of said tube to the exterior of said lower housing, said tear-off tab configured to removably cover said lower section of said tube.
