<p>An olfactory patch comprises a well formed by a reservoir layer, the well is sandwiched between a barrier layer and a permeable layer. The permeable layer defines a pathway for olfactory fluid flow from the well. The flow of the olfactory fluid may be commenced by an initiator mechanism. The olfactory patch may utilize any olfactory fluid or combination of fluids within the same patch. The patch may utilize olfactory fluid which provides aromas or masks odors or has deodorizing capability or the olfactory fluid may contain therapeutic or pest control agents which are released from the patch by aromatization or by direct skin absorption or by inhalation.</p> |
