A dispensing closure (10) for viscous fluids contains a closure body (20), a closure lid (100) and a living hinge structure (110) hingeably connecting the closure lid (100) to the closure body (20). The closure body (20) includes an upper deck (30), a skirt (40) configured and arranged to mount to a product container, and a flow conduit (50) extending through the upper deck (30) to provide a flow path from an interior of the closure (10) to an exterior of the closure (10). The flow conduit (50) includes an entrance orifice (50A) and an exit orifice (SOB), and an inner wall (SOC) extending between the entrance orifice (50A) and the exit office (SOB). To provide the desired flow effect, the inner wall (SOC) includes at least one flow inhibitor structure, such as helically threaded flights (60) extending at least partially inwardly from the inner wall (SOC).
