ABSTRACT:
A dispensing closure for a container includes a closure body, a cap and a hinge body joining the cap to the body. The closure body includes an upper wall having an orifice and further includes an upper skirt depending from the upper wall, and a lower skirt depending from the upper skirt. The lower skirt has a diameter larger than the upper skirt. The cap has an upper wall and a wall flange depending therefrom. A first living hinge joins a first end of the hinge body to the lower skirt. The hinge body is movable from an open position to a closed position in mating relation with the upper skirt. The hinge body and upper skirt are formed with complementary surfaces to provide a flush outer surface contour when mated together. The hinge body and upper skirt further include mating formations to secure the hinge body with the upper skirt. A second living hinge joins a second end of the hinge body to the cap, wherein the cap is movable from an open position to a closed position overlying the upper wall of the closure body. The dual hinge construction allows the cap to have a smaller diameter than the skirt of the closure body.
