Abstract
Dual functional dispensers, wherein the dispensers comprise dispensing units independently capable of dispensing an actively dispersed spray or an evaporative long term dispersible material, comprise active dispensers in combination with passive dispensers of volatile materials. The passive dispenser may comprise the external shell of said dual function dispenser, and may be fashioned of a porous ceramic, plastic, or paper material impregnated with an evaporative passively dispersible material selected from the group consisting of fragrances, air fresheners, deodorizers, odor eliminators, malodor counteractants, insecticides, insect repellants, medicinal substances, disinfectants, sanitizers, mood enhancers, and aroma therapy compositions. The actively dispersed material may be the same or different. Refill units for such dispensers may comprise a spray can and associated control means, and an evaporative dispenser of dispersible material, provided either separately or as an integral unit.
