ABSTRACT:
A volatile material dispensing device is provided, including a reservoir containing a supply of any one of numerous volatile materials having an outlet port with attached tube through which the volatile material flows, a valve and valve adjustment mechanism to control the flow rate through the tube, a lower housing incorporating a pad to receive the volatile material, and a tear-off tab that initially seals the tube and prevents flow until removed by the consumer. Optionally, the device may include an active mechanism, such as a fan, to aid dispersal of the volatile material. The device gives the user control of the intensity of the vapor by providing the ability to adjust the flow through the valve with the valve adjustment mechanism. The device also provides constant vapor intensity over time with a time-release dispersing mechanism delivering a controlled, consistent flow, with an appropriate drip rate.
