Abstract

A closure lid for a beverage drink container in which a door panel secured at an underside of the lid includes a boss protruding through an opening cut in the lid for forward or rearward motion in opening and closing a slotted window through which the beverage in a container would be dispensed upon tilting the container at an angle.

       8 . The closure lid of  claim 7 , wherein each of said first and second pairs of grooved tracks are of molded plastic composition.  
   
   
       9 . The closure lid of  claim 1 , further including a track raised inwardly of said first pair of grooved tracks at said underside, and at an angle with respect thereto to limit forward sliding movement of said panel door.  
   
   
       10 . The closure lid of  claim 7 , further including a track raised inwardly of said second pair of grooved tracks at said underside, and at an angle with respect thereto to limit forward sliding movement of said panel door.  
   
   
       11 . The closure lid of  claim 9 , wherein said first pair of grooved tracks and said further included raised track are of molded plastic composition.  
   
   
       12 . The closure lid of  claim 10 , wherein said first and second pairs of grooved tracks and said further included raised track are of molded plastic composition.  
   
   
       13 . A closure lid for a hot beverage drink container comprising: 
 a top side, an underside, a slotted window cut through said top and undersides inwardly from an edge surface thereof, a first pair of grooved tracks raised from said underside and spanning opposing sides of said window, a second pair of grooved tracks raised at said underside and spanning opposing sides of said window situated inwardly of said first pair of grooved tracks along said underside, a panel door at said underside fitted to glide within said first and second pairs of grooved tracks for selectively opening and closing said window as desired, a boss on said door protruding through said window for finger actuation in operatively sliding said door forward and back through said first and second pairs of grooved tracks in allowing dispensing of beverage drink through said slotted window upon tilting the beverage drink container at an angle.    
   
   
       14 . The closure lid of  claim 13 , constructed of substantially different material composition than the beverage drink container.  
   
   
       15 . The closure lid of  claim 13 , wherein said panel door, said first and second pairs of grooved tracks, and said boss are each of a molded plastic composition.  
   
   
       16 . The closure lid of  claim 13 , also including a track raised inwardly of said second pair of grooved tracks at said underside, and at an angle with respect thereto to limit forward sliding movement of said panel door.  
   
   
       17 . The closure lid of  claim 16 , wherein said first and second pairs of grooved tracks, said panel door, said boss and said raised track are each of molded plastic composition.
