A dispensing closure includes a closure shell of one-piece integrally molded plastic construction having a base for securement to a container neck finish and a lid coupled by a hinge to the base. The base has a deck, a recess extending across the deck from a point adjacent to the hinge, and a dispensing opening in the recess. The lid has a base portion for receipt in the recess in the closed position of the lid and a tongue at an end of the lid remote from the hinge. A latch on the base in the recess engages the tongue on the lid releasably to hold the lid in the closed position. The latch preferably comprises a snap latch that includes an internal bead on the tongue and an external latch element in the recess over which the internal bead is received in the closed position of the lid. The base preferably includes a ledge in the recess against which the tongue abuts, and a pair of ribs for frictionally holding the tongue against the body.
