Cap having expansible back

Abstract

A cap comprises a crown being conjoined at a front end with a visor and at a back end with an expansible portion. The expansible portion extends substantially along the entire rear cap periphery and is attached to the crown substantially between opposite ends of the visor. The expansible portion incorporates an elastic band and is configured to resiliently accommodate different user head sizes.

A cap, comprising a crown being conjoined at a front end with a visor and at a back end with an expansible portion, said expansible portion extending substantially along the entire rear cap periphery and being attached to said crown substantially between opposite ends of said visor, said expansible portion being configured to resiliently accommodate different user head sizes.  
   
   
       2 . The cap of  claim 1 , wherein said expansible portion incorporates an elastic band and has an upper boundary.  
   
   
       3 . The cap of  claim 2 , wherein said back end of said crown is substantially arcuate.  
   
   
       4 . The cap of  claim 3 , wherein said substantially arcuate back end of said crown delineates said upper boundary of said expansible portion.  
   
   
       5 . A cap, comprising a crown being conjoined at a front end with a visor and at a back end with an expansible portion, said expansible portion extending substantially along the entire rear cap periphery and being attached to said crown substantially between opposite ends of said visor, said expansible portion being configured to resiliently accommodate different user head sizes, said expansible portion including an outer peripheral edge adapted to follow the contours of said front end of said crown, said outer peripheral edge residing substantially in the same plane as said front end of said crown.  
   
   
       6 . The cap of  claim 5 , wherein said expansible portion incorporates an elastic band and has an upper boundary.  
   
   
       7 . The cap of  claim 6 , wherein said back end of said crown is substantially arcuate.  
   
   
       8 . The cap of  claim 7 , wherein said substantially arcuate back end of said crown delineates said upper boundary of said expansible portion.  
   
   
       9 . The cap of  claim 8 , wherein said outer peripheral edge of said expansible portion serves as a stretchable rear peripheral cap edge.  
   
   
       10 . A cap, comprising a crown being conjoined at a front end with a visor and at a back end with an elongated expansible portion, said elongated expansible portion extending substantially along the entire rear cap periphery and being attached to said crown substantially between opposite ends of said visor, said elongated expansible portion being configured to resiliently accommodate different user head sizes, said elongated expansible portion including an outer peripheral edge being disposed at a lower elevation than said front end of said crown.  
   
   
       11 . The cap of  claim 10 , wherein said elongated expansible portion incorporates an elastic band and has an upper boundary.  
   
   
       12 . The cap of  claim 11 , wherein said back end of said crown is substantially arcuate.  
   
   
       13 . The cap of  claim 12 , wherein said substantially arcuate back end of said crown delineates said upper boundary of said elongated expansible portion.  
   
   
       14 . The cap of  claim 13 , wherein said lower elevational disposition of said outer peripheral edge is configured to allow at least partial coverage of the user's ears by said elongated expansible portion.  
   
   
       15 . The cap of  claim 14 , wherein said elongated expansible portion is adapted to be folded substantially toward said crown along a first crease.  
   
   
       16 . The cap of  claim 15 , wherein said first crease is adapted to follow the contours of said front end of said crown.  
   
   
       17 . The cap of  claim 16 , wherein said elongated expansible portion is adapted to be folded substantially away from said crown along said first crease to cover at least a portion of user's ears.  
   
   
       18 . The cap of  claim 17 , wherein said elongated expansible portion is adapted to be folded relative to said crown below said first crease.  
   
   
       19 . The cap of  claim 17 , wherein said elongated expansible portion is adapted to be folded relative to said crown above said first crease.  
   
   
       20 . The cap of  claim 14 , wherein said elongated expansible portion is adapted to be folded relative to said crown along at least one crease to provide at least partial coverage of the user's head.  
   
   
       21 . The cap of  claim 14 , wherein said outer peripheral edge is substantially arcuate.  
   
   
       22 . The cap of  claim 21 , wherein said substantially arcuate outer peripheral edge of said elongated expansible portion serves as a stretchable rear peripheral cap edge.  
   
   
       23 . The cap of  claim 1 , wherein said expansible portion is fabricated from at least one woven flexible material.  
   
   
       24 . The cap of  claim 1 , wherein said expansible portion is fabricated from at least one knitted flexible material.
