Abstract
A plastic dome lid for a drinking cup is disclosed which has the capability of functioning as a complete closure lid for the cup and as a drink through lid employing a recloseable flip-open lid segment for this purpose. The dome lid is provided with a lower section that has a downwardly facing annular channel for receiving and engaging the rim of the cup and an upper section which includes a raised C-shaped dome. An intermediate section is provided between the upper and lower sections forming a central area located within and depressed relative to the C-shaped dome. A transverse wall extends from one leg to the other leg within the bite of the C-shaped dome and upwardly from the lower section to a location above the central area and below the upper sections so as to define a raised rib across the bite. A recloseable flip-open segment forms part of the lower section and extends inwardly from a location on the annular channel to a hinge line on the bottom section. The flip-open segment can be separated from the remainder of the lower section and flipped open along the hinge line in a direction towards the wall.
