Patent ID: 6889859

Claim:
A lid for a drinking cup, the lid comprising: a) a rounded top wall having a generally circular periphery; b) an annular outward side wall depending from said rounded top wall outwardly about its periphery; c) an annular mounting portion at the bottom of said annular outward side wall for sealingly engaging the lip of the drinking cup; d) an annular inward side wall depending from said rounded top wall inwardly about its periphery; e) a recessed circular surface engaged to a portion of the bottom of said annular inward side wall, said recessed circular surface comprising a hinge across its center and a non-engaged hatch, said hatch being slightly slanted downwardly allowing back drainage of any portion of the cup's contents that could otherwise accumulate on the recessed circular surface, said hatch sitting against the bottom of the annular inward side wall and being able to open inwardly along the hinge upon external pressure allowing the introduction of a beverage stirring device, additional liquid or condiments into the cup without removal of the lid and so that upon removal of the external pressure, the hatch plastically recovers to its closed position; f. a drinking opening spout located on the annular inward side wall and extending downwardly and narrowly along said annular inward side wall to enable drinking from the cup without removal of the lid, said spout sized to allow the beverage to discharge at a flow rate equivalent to that of a drinking cup without a lid, said spout shaped to enhance contact between the discharging liquid and the inside of the user's upper lip and to further allow non-consumed liquid to drain back into the cup thus preventing pooling of the liquid on the recessed circular surface; g. a circular medium area located on the annular outward side wall directly across the spout, said circular medium area being permeable so as to facilitate the controlled passage of a discharging liquid, said circular medium area's comprising a system selected from the group consisting of a permeable membrane, a permeable fabric, a permeable screen, a plurality of fine baffles, a plurality of fine circular perforations and a plurality of fine slits; and h. an olfactory enhancing means located on the annular inward side wall opposite the spout to enable olfactory perception of the liquid in the cup without removal of the lid.
