12. The cup lid of claim 1 , wherein said spout has a proximal end connected to said lid body and a distal end opposite said proximal end having a height from said proximal end to said distal end, and wherein said height is from about 0.80 inches to about 1.80 inches.

13. The cup lid of claim 1 , wherein said spout has a proximal end connected to said lid body and a distal end opposite said proximal end, wherein said proximal end has a width from said first side wall to said second side wall and said distal end has a width from said first side wall to said second side wall, and wherein said width of said distal end is from about 0.50 inches to about 0.90 inches and said width of said proximal end is from about 0.80 inches to about 1.2 inches.

14. The cup lid of claim 1 , wherein said spout has a proximal end connected to said lid body and a distal end opposite said proximal end, wherein said proximal end has a depth from said front wall to said rear wall and said distal end has a depth from said front wall to said rear wall and said distal end has a depth from said front wall to said rear wall, and wherein said depth of said distal end is from about 0.10 inches to about 0.25 inches and said depth of said proximal end is from about 0.25 inches to about 0.75 inches.

15. An assembly, comprising:

a cup defining an inner volume, said cup having an outer surface opposite an inner surface that defines said inner volume, with a top portion at the open end of said cup; and

a lid including:

a lid body having a lid wall with a top surface and a bottom surface opposite said top surface;

an annular flange having a flange wall extending downwardly from said lid wall that is connectable to said cup, said flange wall having an outer surface and an inner surface opposite said outer surface;

a spout extending from said top surface, said spout having a front wall, a rear wall, a first side wall connecting said front wall and said rear wall on a first side, a second side wall connecting said front wall and said rear wall on a second side opposite said first side, and a top wall, said top wall being connected to said front wall, said rear wall, said first side wall and said second side wall, said top wall being upwardly convex shape forming chamfered edges with said front wall and said rear wall,
