The present dispensing closure system includes a closure base, which can be configured for securement to an associated container, and a lid hingedly connected to the closure base for movement between closed and open positions, wherein in the closed position of the lid, the lid coacts to close and seal a dispensing orifice defined by the closure base. Convenient manipulation of the lid between its closed and open positions is facilitated by the provision of a sliding element mounted on the closure base for sliding, reciprocable movement generally laterally of the closure base. Notably, the sliding element includes a latch portion which coacts with the lid to positively retain the lid in its closed position until manipulation of the sliding element by a user to unlatch the lid. The sliding element includes one or more camming surfaces which coact with the lid to urge it from its closed position to its open position.
