A child-resistant dispensing closure includes a base having a deck with a dispensing opening, a peripheral skirt extending from the deck, and an inner wall extending from the deck for securing the closure to a container. An axial passage extends from the deck between the peripheral skirt and the inner wall, and opens radially outwardly through the peripheral skirt. A pair of spaced ledges are disposed in the axial passage. A lid is molded integrally with the base and is coupled by a hinge to the base so as to be pivotable between a closed position overlying the deck and an open position spaced from the deck. The lid has a latch arm that resiliently extends from a periphery of the lid. The latch arm has a pair of oppositely extending tabs for engagement with the ledges to lock the lid in the closed position. The latch arm is directly manually engageable by a user from a radial direction external to the closure to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so that the lid can be pivoted toward the open position drawing the latch arm out of the axial passage.
