An olfactory patch comprises a well 6 formed by a reservoir layer 2 , the well sandwiched between a barrier layer 3 and a permeable layer 4 . The permeable layer defines a pathway for olfactory fluid flow from the well 6 (B, FIG. 2 ). The flow of the olfactory may be commenced by an initiator mechanism, the same or another mechanism may control or terminate the flow of olfactory. The olfactory patch may utilise any olfactory fluid or combination of fluids within the same patch. The patch may utilise olfactory fluid which provides aromas or masks odours or has de-deodorising capability or the olfactory fluid contains therapeutic agents which are released from the patch by aromatization or by direct skin absorption or by inhalation.
