Abstract
Nasal dilators and strips, methods of their manufacture, and methods for improving the breathing of individuals are provided. The strips and dilators include an elongated substrate, with or without a dilating component or portion, having top and bottom surfaces and a pressure-sensitive adhesive disposed on the bottom surface. The dilator is designed to provide a gentle expanding force to the nasal wall tissue when the dilator is adhesively attached to the nose. This invention further includes a cosmetic fragrance, an aromatic medication and/or transdermal medication disposed on the strips or 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.
