A closure is provided for use in covering an opening in a container and engaging a peripheral rim defining the opening. The closure includes a body for covering the container opening and a plurality of projecting portions that extend from a periphery of the body. The projecting portions are spaced from one another around the periphery of the body, with each formed to surround a portion of the container rim. A ring is connected to the projecting portions and surrounds the container rim. A plurality of retaining fingers are provided, with each fingers spaced from one another and interleaved within the spacing between adjacent projecting portions. The fingers project inwardly from the ring and include a projected end for engagement with the container rim. The projected ends of the fingers include a varied or undulating surface.
