Abstract
A cover for a drink container, preferably a disposable container, having a rim, said cover made from a resilient non-metallic material, preferably a thermoplastic polymer, and comprising a peripheral rim section adapted to fit snugly over the rim of the container and a resilient cover panel extending between the confines of said rim section to cover the container, said cover panel having a weakening line defining a flap and a hinge for the flap, said flap having a raised pull-tab which may be grasped and pulled so that the weakening line may be torn and the flap opened by folding at its hinge section, said cover panel also having a depressed well section which is of such size and shape and so positioned that when the flap is folded over on its hinge, the pull-tab may be nested in the well and the flap thereby retained in an open position.
