A disposable cup lid made of plastics using injection molding techniques and adapted for covering a drinking cup, the disposable cup lid comprising a coupling rim for attaching to a drinking cup, a mouthpiece area, a tab, a breakable connection means connected between said mouthpiece area and said tab, and at least one stop lug downwardly extended from a bottom wall thereof adjacent to said breakable connection means, said tab being pressable downwardly by an external force to break said breakable connection means in opening said mouthpiece area and stoppable by said at least one stop lug in an open position. 
     
     
         2 . The disposable cup lid as claimed in  claim 1 , wherein said breakable connection means is a series of dentations. 
     
     
         3 . The disposable cup lid as claimed in  claim 1 , wherein the number of said at least one stop lug is  2 , and the two stop lugs are downwardly extended from the bottom wall of the disposable cup lid at two opposite lateral sides relative to said tab. 
     
     
         4 . The disposable cup lid as claimed in  claim 1 , wherein each said stop lug comprises a beveled guide portion located on a bottom side thereof and a positioning portion upwardly extended from a back side of said beveled guide portion; said tab comprises at least one outwardly protruding stop portion disposed adjacent to the periphery of the disposable cup lid, said at least one outwardly protruding stop portion being movable over the beveled guide portion of each said stop lug for engagement with said positioning portion of each said stop lug to hold said tab in said open position. 
     
     
         5 . The disposable cup lid as claimed in  claim 1 , wherein said tab comprises a stem upwardly extended from a top side thereof. 
     
     
         6 . The disposable cup lid as claimed in  claim 1 , wherein said tab is substantially shaped like a mushroom, comprising a relatively narrower body extending upwards and terminating in a stem, a relatively wider head forming two reversely outwardly protruding stop portions, and two stop lugs located on the two opposite lateral sides of said relatively narrower body.
