A volatile substance dispenser plugs into an electrical outlet to disseminate a vapor into a selected area. After the volatile material is consumed the dispenser is simply discarded. The combined use of a fixed resistor heat pad screen printed within the dispenser, and a thermal conductor, provides unusually uniform heat to a volatile material absorbent substrate within the dispenser, providing economical vaporization of the volatile material. Specific versions of the invention as a fragrance dispenser are described. A unique infant safe electrical connection for the dispenser is also disclosed.
