Abstract
The drinking cup lid includes a cover portion and at least one tab extending from the cover portion and movable into a retaining position adjacent the sidewalls of the cup to securely attach the lid to the cup while providing a gripping area insulated from the thermal effects of the contents of the cup. The tabs include a retaining groove adapted to receive the rim of the cup and a latching lip for sealingly engaging the rim when the tabs are moved into the retaining position. A gripping portion of each tab is positioned adjacent the sidewalls when the tabs are in the retaining position. The gripping portion is maintained a spaced radial distance from the sidewalls by both a hinge which provides a pivot axis about which the tab rotates and a rib formed by a stiffening groove extending along the tab.
