The present invention relates to external devices for dilating nasal passageways and to the manufacture thereof. More specifically, the external nasal dilator of the present invention usually comprises a resilient sheet, an adhesive layer, and an adhesive-protecting sheet. In some embodiments of the external nasal dilator, the resilient sheet defines a groove for reducing the peel force that results from bending the dilator over the bridge of the nose. In addition to the groove or in lieu thereof, some embodiments of the external nasal dilator comprise a nasal passage region having a reduced width to reduce the peel force. Finally, the dilator can comprise a sheet of adhesive tape, which in some embodiments can provide an instant tack surface to facilitate application of the dilator.

1. An external nasal dilator comprising: a bridge region for primarily contacting a bridge of a nose;a first nasal passage region, adjacent to the bridge region, for primarily contacting a first side of the nose;a second nasal passage region, adjacent to the bridge region and distal to the first nasal passage region, for primarily contacting a second side of the nose;a first end region adjacent to the first nasal passage region and distal to the bridge region; anda second end region adjacent to the second nasal passage region and distal to the bridge region;wherein the first nasal passage region has an average width that is substantially less than the average width of the bridge region; andfurther comprising an adhesive layer defining a first major surface and a second major surface;a resilient sheet, defining a third major surface and a fourth major surface, the third major surface and the fourth major surface terminating at a first edge and at a second edge opposite the first edge forming a first direction between the first edge and the second edge, the resilient sheet being superposed on the adhesive layer such that the fourth major surface contacts the first major surface, wherein the third major surface, the fourth major surface, or both comprise multiple grooves beginning at the first edge and terminating at the second edge at least one groove extending across each of the first end region and the second end region and at least one groove extending across each of the first nasal passage region and the second nasal passage region, which when the resilient sheet is in a planar orientation, the groove is curved along the first direction; andan adhesive-protecting sheet, defining a fifth major surface and a sixth major surface, superposed on the adhesive layer such that the fifth major surface contacts the second major surface, wherein the adhesive-protecting sheet comprises a first material suitable for protecting the adhesive layer and for being removably adhered to the adhesive layer. 2. The external nasal dilator of claim 1, wherein the third major surface comprises at least one curved groove. 3. The external nasal dilator of claim 1, wherein the fourth major surface comprises at least one curved groove. 4. The external nasal dilator of claim 1, wherein the adhesive layer comprises a hydrocolloid. 5. The external nasal dilator of claim 1, wherein the resilient material is selected from the group consisting of PET, boPET, PETG, HDPE, and polyester. 6. The external nasal dilator of claim 1, wherein the first material is selected from the group consisting of polypropylene, a similar thermoplastic resin, and a paper-based material. 7. The external nasal dilator of claim 1, further comprising a sheet of adhesive tape superposed on the resilient sheet such that the sheet of adhesive tape adheres to the third major surface.
