A plastics closure (10) for a container mouth is provided with flow regulation means for selectively controlling the flow of contents dispensed. The means comprise at least two parts (30,70) which can be moved relative to one another. Each part has at least one dispensing orifice (39,90). The parts (30,70) are adapted so that their respective orifices can be aligned at least partially with respect to each other and with the container mouth. The degree of overlap between the respective orifices defines a common dispensing area to allow control of the flow rate.
