Abstract

A liquid container includes a brim forming a mouth opening into a product receiving chamber formed in a cup. A lid is coupled to the rim to close the mouth of the cup.

1 . (canceled) 
     
     
         2 . A lid for a cup, the lid comprising
 a ring-shaped brim mount having a round shape with a center point located on a central axis of the lid, the ring-shaped brim mount being adapted to couple to a brim included in a cup,   a central closure including an elevated basin arranged to lie in spaced-apart relation to the ring-shaped brim mount and formed to include a sip aperture and a well aperture, a product-retaining shell coupled to a perimeter of the elevated basin and arranged to extend toward and couple to the ring-shaped brim mount, a well coupled to the elevated basin and arranged to extend dowardly toward the ring-shaped brim mount, and a nub coupled to the elevated basin,   a sip flap including a sip-flap tab and a sip-flap hinge arranged to extend between and interconnect the sip-flap tab to the elevated basin to allow the sip-flap tab to move between a closed position in which the sip-flap tab lies in and closes the sip aperture and an opened position in which the nub extends into the well aperture,   wherein the sip flap lies between the ring-shaped brim mount and a top wall of the product-retaining shell.   
     
     
         3 . The lid of  claim 2 , wherein the product-retaining shell includes a product-retaining wall arranged to lie in spaced-apart radial relation to the elevated basin and a top wall arranged to extend between and interconnect the product-retaining wall and the elevated basin. 
     
     
         4 . The lid of  claim 3 , wherein a portion of the nub extends above the top wall when the sip-flap tab is in the closed position. 
     
     
         5 . The lid of  claim 4 , wherein the elevated basin is arranged to extend downwardly away from the top wall. 
     
     
         6 . The lid of  claim 5 , wherein the elevated basin includes a first planar portion formed to include the sip aperture. 
     
     
         7 . The lid of  claim 5 , wherein the elevated basin includes a first planar portion formed to include the sip aperture and a second planar portion formed to include the well aperture. 
     
     
         8 . The lid of  claim 7 , wherein the sip aperture and the well aperture are located between the ring-shaped brim mount and the top wall. 
     
     
         9 . The lid of  claim 5 , wherein the elevated basin includes a first planar portion formed to include the sip aperture and a second planar portion formed to include the well aperture and the first planar portion and the second planar portion are coplanar to one another. 
     
     
         10 . The lid of  claim 2 , wherein the sip-flap hinge is located between the sip aperture and the well aperture. 
     
     
         11 . The lid of  claim 10 , wherein the nub is arranged to extend above the product-retaining shell when the sip-flap tab is in the closed position. 
     
     
         12 . The lid of  claim 11 , wherein the sip-flap tab pivots about a tab axis relative to the elevated basin about  180  degrees to move from the closed position to the opened position and the tab axis is arranged to be parallel to the planar portion. 
     
     
         13 . The lid of  claim 12 , wherein the elevated basin includes a first planar portion formed to include the sip aperture. 
     
     
         14 . The lid of  claim 13 , wherein the sip-flap tab is about parallel to the first planar portion of the elevated basin when the sip flap is in the closed position. 
     
     
         15 . The lid of  claim 13 , wherein the elevated basin includes a second planar portion formed to include the well aperture. 
     
     
         16 . The lid of  claim 15 , wherein the first planar portion and the second planar portion are coplanar to one another. 
     
     
         17 . The lid of  claim 2 , wherein the sip-flap tab is formed to include an inner edge and an outer edge surrounding the inner edge, the nub is coupled to the sip-flap tab along the inner edge to lie in a fixed position on the sip-flap tab for movement therewith relative to the elevated basin, and the sip-flap hinge is coupled to the sip-flap tab at the outer edge. 
     
     
         18 . The lid of  claim 17 , wherein the nub is arranged to extend above the product-retaining shell. 
     
     
         19 . The lid of  claim 18 , wherein the well is arranged to extend below the elevated basin. 
     
     
         20 . The lid of  claim 18 , wherein the nub has a cross-sectional shape that is geometrically similar to a cross-sectional shape of the well. 
     
     
         21 . The lid of  claim 18 , wherein the elevated basin includes a first planar portion formed to include the sip aperture and a second planar portion formed to include the well aperture and the second planar portion has a downward negative slope.
