ABSTRACT:
A plastic closure for a container mouth is provided with a flow regulator for selectively controlling the flow of contents during dispensing. The flow regulator includes at least two parts which can be moved relative to each other. Each part has at least one dispensing orifice. The parts are constructed such that respective orifices can be aligned at least partially with respect to each other and with respect to the container mouth. The degree of overlap between the respective orifices defines a common dispensing area to control the flow rate during contents dispensing.
