Nasal dilators (11) strips (11) and methods of their manufacture and methods for improving the breathing of individuals are provided. The strips (11) and dilators (11) include an elongated substrate (30, 40) with or without a dilating component or portion (60), having top (62) and bottom (42) surfaces and a pressure sensitive adhesive (32) disposed on the bottom surface. The dilator is adhesively attachable to a user's nose. This device further includes cosmetic fragrance, aromatic medication or transdermal medication disposed on the strips for dilators. In order to improve the shelf life and in use olfactory effectiveness of such products, fragrance delivery mechanisms are used. Separation of volatile oils and adhesives are also provided to minimize adhesive residue.

L'invention concerne des dilatateurs de narines (11), des bandelettes (11), des procédés pour leur fabrication, ainsi que des procédés d'amélioration de la respiration d'individus. Les bandelettes (11) et les dilatateurs (11) comprennent un substrat oblong (30, 40), avec ou sans composant ou portion de dilatation (60), des surfaces supérieure (62) et inférieure (42) et un adhésif autocollant (32) disposé sur la surface inférieure. Le dilatateur peut être fixé sur le nez de l'utilisateur au moyen d'un adhésif. Ce dispositif comprend, en outre, une fragrance cosmétique, une médication aromatique ou une médication transdermique disposée sur les bandelettes destinées aux dilatateurs. De façon à améliorer la durée de vie ainsi que l'efficacité olfactive de tels produits, on utilise des mécanismes de libération de fragrance. On utilise aussi une séparation des huiles volatiles et des adhésifs afin de minimiser le résidu d'adhésif.
