  • Device for dispensing volatile materials
    Patent number: 6154607
    Abstract: Disclosed herein are devices for dispensing volatile vapors such as insecticides. Table-like carrier members provide a compartment for the volatile material. One or more table leg structures extend down from a table top to support a cavity in the table top a distance above a burner element. This results in more moderate and uniform heating, thereby permitting efficient release of the volatile material over a longer period of time. In some versions the table leg structures and table top are formed as separate pieces and designed to permit side-to-side ventilation under the volatile.
