Abstract
A container lid convertible into a spoon constitutes a one piece water-impermeable sheet of a thermoplastic resin including a flat peripheral ring having a circular outer circumference defining an inner area of three-dimensional configuration including a diametral trough the front end of which flares outwardly and terminates in the plane of the ring. Wings extend laterally outwardly from the side edges of the trough. The front ends of the wings are located at the front end of said side edges. The side edges are weakened whereby as opposite points of the periphery of the lid are squeezed together the rear portions of the wings and of the trough collapse upon one another to form a spoon handle and the front portion of the trough is narrowed and deepened to form a spoon bowl.
