Abstract

A cap assembly for use in conjunction with a container having a base portion and a top portion. The base portion has a neck and a lip. The neck and lip are dimensioned to be attached to the container. The base portion has a straw hole and an air hole. The top portion is attached to the base portion by a flexible bridge. The top portion has a gripping flange for sealing the straw hole and an air hole stopper for sealing said air hole. Also integral to the top portion is a clip for holding the top portion to said base portion. A straw is adapted to be positioned within the straw hole of the base.

1 . A cap assembly for use in conjunction with a container, comprising: 
 a cap having a base portion and a top portion attached to said base portion, said base portion having a neck and a lip, said neck and lip dimensioned for attachment to the container, said base portion having a straw hole, said top portion having a gripping flange for sealing said straw hole, an air hole stopper for sealing said air hole, and a clip for holding said top to said base portion;    a straw adapted to be positioned within said straw hole of said base.    
   
   
       2 . A cap assembly as set forth in  claim 1 , said base portion further comprising an air hole.  
   
   
       3 . A cap assembly as set forth in  claim 1 , said top portion attached to said base portion by a bridge.  
   
   
       4 . A cap assembly as set forth in  claim 1 , said top portion further comprising a clip for holding said top portion to said base portion.  
   
   
       5 . A cap assembly as set forth in  claim 1 , said straw further comprises an inner straw and an outer straw, said inner straw having a diameter that is smaller than a diameter of said outer straw, so that said inner straw can slidingly engage said outer straw and extend from a closed position to an open position.  
   
   
       6 . A cap assembly as set forth in  claim 5 , wherein said inner straw is held by said outer straw by frictional engagement.  
   
   
       7 . A cap assembly as set forth in  claim 5 , wherein said inner straw further comprises a tab for sliding said inner straw in said outer straw.  
   
   
       8 . A cap assembly as set forth in  claim 5 , further comprising a float attached to said inner straw so that said inner straw is biased towards an extended drinking position when the container is filled with a liquid.  
   
   
       9 . A cap assembly as set forth in  claim 8 , further comprising a stopper attached to said inner straw so that when said straw extends out of the container, said stopper impedes movement of said inner straw when said inner straw is in said extended drinking position.  
   
   
       10 . A cap assembly as set forth in  claim 1 , said straw further comprising pleats so that said straw can extend from a closed position to an open position.  
   
   
       11 . A cap assembly as set forth in  claim 1 , said cap assembly formed from plastic.
