Nasal dilator devices

A nasal dilator device comprising:

• a substantially U-shaped body including:
• a central portion arranged to span a septum of a nose when worn by a user, and first and second leg members extending from the central portion in a first plane;
• a first cantilever rib member extending laterally outward from an end of the first leg member of the U-shaped body in a second plane, wherein the first cantilever rib member is curved or arcuate along its length and extends to a distal end in the second plane;
• a second cantilever rib member extending laterally outward from an end of the second leg member of the U-shaped body in a third plane, wherein the second cantilever rib member is curved or arcuate along its length and extends to a distal end in the third plane;
• wherein the second and third planes are converging planes, and wherein each of the second and third planes forms an obtuse angle with the first plane;
• and
• at least one projection protruding from and extending longitudinally along at least a portion of a length of each of the first and second cantilever rib members, wherein the at least one projection is formed as a ridge or a flange that is disposed at and extends along a longitudinal edge of the first and second cantilever rib members;
• wherein the first and second cantilever rib members extend away from each other at their proximal ends, and wherein the first and second cantilever rib members extend towards each other at their distal ends.
