Abstract:
A disposable lid for a drinking cup comprising:a substantially planar cover portion; an annular mounting portion surrounding a periphery of said planar cover portion for sealingly engaging the drinking cup; said annular mounting portion including a downwardly extending annular skirt; a tear-back section extending from said annular skirt to a medial portion of the lid, said tear-back section being formed within a quadrant of said annular mounting portion and said planar portion; a raised protrusion extending from an upper surface of said tear-back section of the lid, said raised protrusion having a circumferential dimension less than a corresponding circumferential dimension of said tear back section; a hinge region located in said quadrant of said planar cover portion; and a recess formed in said quadrant of said planar cover portion of the lid on an opposing side of said hinge region from said raised protrusion, said recess having an inner surface extending from said planar cover portion to a bottom surface, said recess having a circumferential dimension equal to or less than said circumferential dimension of said protrusion such that said tear-back section of the lid may be displaced from the lid and pivoted about said hinge region until said circumferential dimension of said raised protrusion is received within said circumferential dimension of said recess, wherein said protrusion frictionally engages said inner surface of said recess to retain said tear-back section of the lid in an open position.
