A device (10) for administering an active agent to the skin or mucosa of an individual comprising a laminated composite of an adhesive overlay (26), a backing layer (14) underlying the central portion of the adhesive overlay, an active agent-permeable membrane (16), the backing layer and membrane defining a reservoir (12) that contains a formulation of the active agent, a peel seal disc (20) underlying the active agent-permeable membrane, a heat seal (22) about the periphery of the peel seal disc, the active agent-permeable membrane and the backing layer and a removable release liner (24) underlying the exposed overlay and peel seal disc. The adhesive layer is above and peripheral to the path of the active agent to the skin or mucosa and is protected from degradation by the components of the reservoir by a multiplicity of heat seals. The peel seal disc protects against release of the active agent-containing reservoir and the release liner protects the adhesive from exposure to the environment prior to use.

Dispositif (10) conçu pour appliquer une substance active sur la peau ou les muqueuses d'un individu, qui est constitué des parties suivantes: un composite laminaire d'un opercule adhésif (26), une couche dorsale (14) sur laquelle repose la partie centrale de l'opercule, une membrane active (16) perméable à la substance administrée, la couche dorsale et la membrane qui délimitent un réceptacle (12) contenant la formulation de la substance active, une rondelle pelable (20) sur laquelle repose la membrane active perméable à la substance, un joint à thermoscellage (22) sur le pourtour de la rondelle pelable. La membrane active perméable à la substance, la couche dorsale et un revêtement intérieur amovible (24) de diffusion sont à la base de la partie exposée de l'opercule et de la rondelle pelable. Le revêtement adhésif est placé au-dessus et en bordure de la trajectoire de la substance active vers la peau et les muqueuses et il est protégé de la dégradation des composants du réceptacle par plusieurs joints à thermoscellage. La rondelle pelable sert de protection contre la diffusion de la substance active contenue dans le réceptacle et le revêtement intérieur de diffusion empêche la partie adhésive d'être exposée à l'environnement extérieur avant toute utilisation.
