A cigarette package closure comprising a frame and a one-piece cover of self-hinging plastic material mounted on the frame. The cover includes a closure section, a lid and a hinge for joining the lid to the closure section for pivotal movement between a closed position and an open position. The inner surface of the cover has inner surface regions which are configured and arranged so that by urging such regions toward each other the lid is urged toward the open position. A spring confronts the inner surface of the cover and urges the surface regions toward each other to thereby bias the lid toward the open position. A latch mechanism on the frame and the lid releasably holds the lid in the closed position.
