A dispensing closure includes a base and a lid of one-piece integrally molded plastic construction. The lid is hinged to the base for movement between an open position spaced from the base and a closed position overlying the base. The base has a deck with an outer surface, a dispensing opening, a radially inwardly and axially outwardly facing conical surface extending from the dispensing opening to the outer surface of the deck, and a radially outwardly facing first snap/seal bead surrounding the deck adjacent to the outer surface. The lid has a pintle for receipt in the dispensing opening, a wall spaced radially outwardly from the pintle and a radially inwardly facing second snap/seal bead on the wall for engagement with the first snap/seal bead on the base. The pintle on the lid is sufficiently long as compared to the surrounding wall on the lid to engage the conical surface and align the snap/seal beads as the lid is moved toward the closed position and the snap/seal beads are spaced from each other. The second snap/seal bead is received by sealing snap-fit over the first bead and the pintle is spaced from the dispensing opening in the fully closed position of the lid.
