 a top wall having a generally circular periphery, an annular side wall downwardly depending from said top wall about its periphery, an annular mounting portion at the bottom of said side wall for sealingly engaging the lip of the container, a drink opening in said top wall adjacent said periphery to enable drinking from the container without removal of the closure lid, a recessed portion in said top wall for receiving the upper lip of a person drinking from the container, a pair of oppositely positioned annular tracks extending upwardly above said top wall from inside and outside edges of said side wall, and a panel door slidable about the periphery of top wall in covering all, or any portion, of said drink opening.    
   
   
       2 . The closure lid of  claim 1  wherein said panel door includes a pair of wing sections positioned beneath said annular tracks and of dimension to be captured in position thereby when slid about the periphery of said top wall.  
   
   
       3 . The closure lid of  claim 2 , also including a pair of bosses on said top wall on either side of said drink opening for limiting movement of said panel door along said top wall in uncovering said drink opening.
