| description | Embodiments of the invention are directed toward devices for emitting a volatile substance, and associated methods of producing such devices. In one embodiment, the delivery device for a volatile substance includes an active layer that is created from a dried polymer solution that contains the volatile substance. A release liner is in direct contact with the active layer, and covers a side of the active layer. The polymer solution may include thickeners, plasticizers, dyes, and preservatives. The devices may deliver volatile substances such as fragrances, masking odors, or therapeutic agents. Some embodiments of the invention are directed toward a patch by positioning a barrier layer on the active layer; the barrier layer may adhere to a surface, and isolate the surface from the active layer. Other embodiments are directed toward controlling the rate of delivery of the volatile agents from patches and other volatile delivery devices.
Dans différentes formes de réalisation, la présente invention concerne des dispositifs permettant l'émission d'une substance volatile, et des procédés connexes permettant de produire de tels dispositifs. Dans une forme de réalisation particulière, ce dispositif de libération de substance volatile comprend une couche active formée à partir d'une solution polymère séchée qui contient la substance volatile. Une couche de revêtement détachable entre en contact direct avec la couche active et recouvre un côté de cette dernière. La solution polymère peut contenir des épaississants, des plastifiants, des colorants et des agents conservateurs. Ces dispositifs peuvent libérer des substances volatiles telles que parfums, odeurs de masquage, ou agents thérapeutiques. Certains formes de réalisation concernent un timbre transdermique, obtenu en recouvrant la couche active d'une couche isolante. La couche isolante adhère sur une surface et isole cette dernière de la couche active. D'autres formes de réalisation comprennent une régulation de la vitesse de libération des agents volatils à partir des timbres ou d'autres dispositifs de libération de substances volatiles. |
