ABSTRACT:
A fragrance cartridge comprising a reservoir containing a fragrance material and provided with channels to permit ingress of carrier gas into the reservoir and egress of fragrance-containing carrier gas from the reservoir, the channels being defined by capillaries having internal diameter and length dimensions sufficient to act as closure means to prevent, or substantially prevent, leakage of fragrance from the reservoir into a head space external of the cartridge when carrier gas flow is interrupted. The cartridge can be used for example to enhance the sensorial perception of a viewer, listener or consumer of an audio and/or visual performance or presentation, by passing fragrance borne on the carrier into a head space local to the listener, viewer or consumer.
