    Patent number: 7591389
    Abstract: A disposable lid for a drinking cup includes a cover portion and a sliding member that is configured to slidably fit into a trench in the cover portion. The trench includes a drink opening on a floor of the trench and the sliding member is configured to cover and uncover the drink opening. In one embodiment, the sliding member includes side portions that extend longitudinally and upwardly from a central portion of the sliding member such that an outer edge of each side portion is located above the central portion of the sliding member.
