摘要： A disposable drink-thru lid (10) for a drinking cup (12) includes an annular mounting portion (18) for sealingly engaging the drinking cup, an annular trough (36), provided about an inner periphery of the annular mounting portion and an annular side wall (24) extending upwardly from the trough to a top land in the form of an annular ridge (26) adjacent an uppermost extremity of the annular side wall. The top portion of the lid includes a crown region (44) having a periphery adjacent the annular ridge (26). The annular ridge is asymmetrical, having a widened region accommodating a drink-thru opening (20) and a narrowed region diametrically opposed to the widened region of the annular ridge. The periphery of the crown region lies in a first substantially horizontal plane while the annular ridge includes a substantially planar surface with this surface lying in a plane above the plane defined by the periphery of the crown region thereby forming a retaining wall (50) for retaining a container placed thereon.
