A closure for a container is disclosed having a body portion, a top portion, and a plurality of sealing rings. The body portion has an open bottom formed of a skirt and an end wall defining an opening. The top portion has a flap that is movable from a closed position where the opening is covered to an open position where the opening is at least partially uncovered to allow for matter to be dispensed. The plurality of sealing rings are within the skirt beneath the end wall and comprise (1) a first ring with a sealing surface provided a first radial distance from the skirt and a first axial distance from the end wall and (2) a second ring with a sealing surface provided a second radial distance from the skirt and a second axial distance from the end wall. The first radial distance is different than the second radial distance and the first axial distance is different than the second axial distance. The sealing surface of the first ring is configured to fit over a mouth of a receptacle having a first diameter and the planar sealing surface of the second ring is configured to fit over a mouth of a receptacle having a second diameter.
