Abstract
A lid for a liquid container having a substantially circular opening is disclosed. The lid includes a drinking spout and a cover integrally connected to a portion of the lid by means of a connecting member, with a cover adapted to fit over the drinking spout in friction-fit relationship. The lid of the invention permits removing the cover and resealing the cover with one hand. In the sealed position, the lid provides a liquid tight seal against spilling through the drinking spout.
