Abstract
A hot beverage lid having thermal protective flex-guards or flaps extending from opposite sides of a cover portion of the lid for protecting a consumer's fingers from heat emanating from the side of a cup. A first flap extends a first distance from under a drinking opening having sufficient area for a thumb. A second flap extends a second distance which is greater than the first flap from the opposite side of the lid and has sufficient area for at least two fingers. Each flap is contoured to conform to the curvature or the sidewall of the cup and each flap comprises swirled rib embossing for improved retention against fingers holding the cup. The top of the cover portion is concave with a hole in the center to allow liquid spillage to reenter the cup. Also, a channel surrounding the base of a circular plateau on top of the cover of the lid is provided for collecting fluid spillage.
