A reusable lid for a beverage cup or can [10]includes a round flat cover plate [20]which covers the rim of the cup to prevent dirt and insects from entering. The cover plate is held in place by a rubber torsion rod [30]which attaches perpendicularly to the plate near the edge. The other end of the rod is attached to a suction cup [40]which holds to the side of the cup. The plate is normally in a position to close the cup; it is shown displaced to one side in the drawing, as when drinking. The plate is pushed to one side with a finger. The rubber rod returns the plate to the closed position upon release. A strap with VELCRO buckle, or an elastic band around the cup, may substitute for the suction cup. The torsion rod may also be permanently attached to the cup.

A finger openable lid for closing a beverage cup, said cup of the type having a rim defining a plane, said lid comprising: a cover plate sized and shaped to cover said rim in a closed position to prevent insects and dirt from entering said cup, said cover plate when in said closed position generally coplanar with said plane of said rim; a hinge joining said cover plate to said cup, said hinge having an axis of relative rotation perpendicular to said plane of said rim, said cover plate is slidably displaceable from said closed position to an open position wherein said cover plate is generally coplanar with said plane of said rim and is displaced from said rim for drinking access to said rim, said hinge including an elongated member of elastic material, said member having an upper end attached to said cover plate and a lower end attached to said cup, said elongated member generally perpendicular to said plane of said rim when said cover plate is in said closed position, said elongated member so attached to said cover plate and to said cup that elastic stresses in said elongated member are minimized when said cover plate is in said closed position, whereby, said member may elastically deform in torsion when said cover plate is moved away from said closed position to said open position, and, said cover plate will be resiliently urged to return to said closed position by increased stress in said member.
