A hinged lid for a container receptacle is provided. The lid structure includes a top attached to a mount structure by a “living” hinge. The mount structure is designed for mounting the lid to an open free end of the receptacle. The lid is provided with a retaining mechanism adapted for maintaining the mount structure in a folded position with respect to the top of the lid thereby enabling the lid to be placed on a receptacle using an automatic lidding machine. The retaining feature includes a projection and a recess, wherein the projection is adapted for begin received within the recess. In one embodiment, the projection extends from the mount structure and is adapted to be received within a recess defined in the lid's top. In another embodiment, the projection extends from the lid's top and is adapted to be received within a recess defined in the mount structure.
