Stretchable cap structure with expandable peak board

Abstract

A stretchable cap structure being comprised of a crown, a sweatband and a peak, the crown portion is composed of a plurality of panels, wherein at least front panels are stretchable, the sweatband is composed of at least a front segment of stretchable band, the peak portion is formed from a peak board having at least a cleft and covered with stretchable fabric. The crown, the sweatband and the peak are sewn together to form the cap. The aforesaid cleft(s) of the peak board is/are provided on the rear section of the peak board adjacent to the crown, so that the portion of the crown adjacent to the peak and the peak portion itself are both expandable by splitting the cleft(s) when the cap is in its stretched state. By providing expandable peak and the stretchable crown, the entire cap is endued with uniform flexibility to thereby be capable of custom fitting all wearers within a wider range of head sizes and different shapes, and to increase the applicability of the cap; while the flexibility of the cap does not affect the aesthetic appearance of the entire cap.

1 . An stretchable cap structure comprising: 
 a crown comprised of a plurality of panels, and a sweatband combined together; and    a peak sewn in front portion of said crown at the lower peripheral edge on the outside of the cap, having an expandable and restorable peak board.    
     
     
         2 . The stretchable cap structure as in  claim 1 , wherein, 
 said peak board is provided on the edge thereof adjacent to said crown with at least a cleft, the fringe end of said cleft(s) is/are disposed at said edge of the peak board; said cleft(s) is/are split when said peak board is in its stretched state, so that there is/are gap(s) in said edge of said peak board, and said gap(s) is/are closed when said peak board is in its natural state.    
     
     
         3 . The stretchable cap structure as in  claim 1 , wherein, 
 said panels of said crown are made of elastic fabric and or with at least front panels are stretchable.    
     
     
         4 . The stretchable cap structure as in  claim 1 , wherein, 
 said sweatband is made of elastic material and is sewn on the inner bottom of said crown, or with at least front segment corresponding to the position of the peak is stretchable.    
     
     
         5 . The stretchable cap structure as in  claim 3  and  4 , wherein, 
 said peak is sewn together with said front panels of said crown and said front segment of said sweatband is connected with said front panels of said crown.  
 
     
     
         6 . The stretchable cap structure as in  claim 3  and  4 , wherein, 
 said peak is formed from said expendable and restorable peak board and covered with stretchable fabric thereon.  
 
     
     
         7 . The stretchable cap structure as in  claim 2 ,  3  or  4 , wherein, 
 said front panels of said crown and said front segment of said sweatband and said peak board are coordinated to stretch and restore synchronically.  
 
     
     
         8 . The stretchable cap structure as in  claim 2 , wherein, 
 said cleft at the other end of each said cleft opposite to said fringe end, is shaped with round hole to prevent further splitting when said peak board is in its stretched state.    
     
     
         9 . The stretchable cap structure as in  claim 1 , wherein, 
 said crown is comprised of a plurality of stretchable panels.    
     
     
         10 . The stretchable cap structure as in  claim 1 , wherein, 
 said sweatband is of a single segment and is made of stretchable material.
