A lid is provided for use as a cover on a beverage container or other dispensing device, wherein the lid includes a dispensing spout therein for dispensing of the container contents therefrom. A flexible connector arm extends around at least a portion of the periphery of the lid and includes a fixed end fixedly attached to the lid at a first arcuate position thereof and a free end frangibly connected to the lid by a frangible tab located at a second arcuate position of the lid. The free end of the connector arm can be detached from the lid by tearing along a tear line provided in the connector arm spaced radially outwardly from the frangible tab. In this manner, detaching of connector arm from the lid occurs by a discrete tear line propagated through the connector arm, rather than through the lid flange, thereby allowing for detachment of the connector arm from the lid without compromising the integrity of the seal between the lid and the cup. A plug may be provided near the free end of the connector arm, which such plug may be removably inserted into dispensing spout of the lid once the connector arm is detached from the lid.

I claim: 1. A lid for use as a cover for an open-topped container, comprising: a top wall; a sidewall depending downwardly from said top wall; and, a connector arm extending from said sidewall, said connector arm having a fixed end fixedly attached to said sidewall and a free end removably attached
I claim: 1. A lid for use as a cover for an open-topped container, comprising: a top wall; a sidewall depending downwardly from said top wall; and, a connector arm extending from said sidewall, said connector arm having a fixed end fixedly attached to said sidewall and a free end removably attached to said sidewall, said free end of said connector arm being attached to said sidewall by a connecting tab, wherein said free end of said connector arm includes a tearline spaced radially-outwardly from said connecting tab and said tearline extends annularly beyond said connecting tab. 2. The lid according to claim 1, wherein said tearline extends along a path that is generally parallel to a line tangent to the sidewall. 3. The lid according to claim 1, wherein said connecting tab is defined by an interruption in a scoreline provided between said connector arm and said sidewall. 4. The lid according to claim 1, wherein said sidewall includes an annular vertical segment depending downwardly from said top wall, an annular sealing flange depending downwardly from said vertical segment, and an annular skirt projecting from said sealing flange, wherein said connector arm extends from said annular skirt. 5. The lid according to claim 1, wherein said connector arm extends between first and second annular positions of said lid. 6. The lid according to claim 5, wherein said second annular position is angularly spaced from said first annular position by an angle less than or equal to 180 degrees. 7. The lid according to claim 1, wherein said connector arm includes a closure plug located near said free end thereof. 8. The lid according to claim 1, wherein said top wall includes a dispensing spout. 9. The lid according to claim 8, wherein said connector arm includes a closure plug located near said free end thereof, and wherein said closure plug is adapted to be removably inserted at least partways into said dispensing spout. 10. The lid according to claim 9, wherein said top wall includes a recess adapted to receive said closure plug at least partways thereinto. 11. The lid according to claim 10, wherein said connector arm is adapted to move between a first and second position, wherein said closure plug is inserted at least partways into said dispensing spout when said connector arm is in said first position and wherein said closure plug is inserted at least partways into said recess when said connector arm is in said second position. 12. The lid according to claim 1, wherein said tearline defines a frangible portion of said connector arm that remains affixed to said sidewall when said connector arm is detached therefrom. 13. The lid according to claim 12, wherein said frangible portion of said connector arm may be removed from said sidewall after said connector arm is detached therefrom. 14. The lid according to claim 1, wherein said connector arm is adapted to be detached from said sidewall without tearing said sidewall. 15. The lid according to claim 14, wherein applying a shearing force to said tearline propagates a tear along a path through said connector arm in a direction towards a scoreline provided between said connector arm and said sidewall. 16. The lid according to claim 1, wherein said connector arm includes at least one hinge depressions. 17. The lid according to claim 1, further comprising a scoreline provided between said connector arm and said sidewall. 18. The lid according to claim 17, wherein said scoreline is a cut line.
