  • Beverage container lid
    Publication number: 20180265265
    Abstract: A lid for sealing a tumbler or other type of beverage container. The lid features a cover and a sidewall, as well as a resilient drink opening plug that is removably tethered to the cover. The cord that tethers the plug is flexible, but is pre-formed into a pair of parabolic arcs that help prevent the cord from wildly dangling or flopping into a user's face while drinking.
