Hair Roller

Abstract

A hair roller includes a plurality of spaced apart outwardly convex sections separated from one another by a plurality of outwardly concave sections. Openings are formed through at least the convex sections to facilitate a flow of air. Retainers can be provided for urging the hair into the outwardly concave section of the roller.

1 . A tubular hair roller having opposite first and second longitudinal ends and a tubular wall extending between the ends, the tubular wall including a plurality of spaced apart outwardly convex sections joined consecutively to one another by a plurality of spaced apart outwardly concave sections, a plurality of apertures extending through at least the convex sections into interior portions of the roller for facilitating a flow of air in proximity to hair wound around at least the convex sections of the roller. 
   
   
       2 . The roller of  claim 1 , wherein the convex sections define sections of a common cylinder and are generated about a common longitudinal axis extending centrally through the roller. 
   
   
       3 . The roller of  claim 2 , wherein the outwardly concave sections are cylindrically generated about axes that are aligned parallel to the longitudinal axis of the roller. 
   
   
       4 . The roller of  claim 3 , wherein the respective outwardly convex sections each extend through substantially equal circumferential arcs. 
   
   
       5 . The roller of  claim 4 , wherein the respective outwardly convex sections are spaced from one another by substantially equal circumferential distances. 
   
   
       6 . The roller of  claim 5 , wherein the circumferential extent of each of the outwardly convex sections is substantially equal to the circumferential distance between adjacent outwardly convex sections. 
   
   
       7 . The roller of  claim 1 , further comprising a plurality of retainers configured for urging hair into the respective concave sections of the roller. 
   
   
       8 . The roller of  claim 7 , wherein each of the retainers is configured for releasable engagement with the roller at the opposed longitudinal ends of the roller. 
   
   
       9 . The roller of  claim 8 , wherein the plurality of retainers comprise a plurality of retainers configured for nested disposition at radially spaced positions in the respective concave sections. 
   
   
       10 . The roller of  claim 1 , wherein the generally tubular roller is of substantially uniform thickness.
