Abstract
A disposable plastic lid with folding side tabs for holding and drinking from hot beverage cups. The lid is applied in the usual fashion to the pre-filled beverage cup. A shorter tab adjacent the drinking spout accommodates the user's thumb. A longer tab opposite the spout accommodates a multi-finger opposing grip. There is a additional top side finger grip in the lid opposite the drinking spout. The side tabs are attached by two point hinge mechanisms with a slit running between the hinge points along the radius of the flange dividing the tab from the flange. The flange retains its full diameter about the circumference of the lid. The tabs are pre-formed with a raised rib pattern and shaped to fit the curvature of the sidewall of the cup. The two point hinge allows the tabs to be folded down and inward below the lid flange into contact with the sidewall of the cup, providing thermal insulation to the user's grip. The two point hinge mechanism and conforming sidetab minimizes structure protruding beyond that of the lid flange.
