Abstract

Disclosed herein are dispensers for dual functional use, wherein the dispensers are independently capable of dispensing a spray or an evaporative long term dispersible material. Also disclosed are refill units for such dispensers, which refill units comprise a spray can and associated control means, and an evaporative dispenser which may be activated by removal of a covering membrane which is impermeable to a volatile dispersible material. The spray and the evaporative volatile dispersible may or may not be the same material, permitting the consumer greater flexibility and choice.
