Abstract
A closure for a container having a container opening is provided herein. The closure includes an annular top having an inner skirt depending downwardly from an inner perimeter of the annular top and having an outer skirt depending downwardly from an outer perimeter of the annular top. An annular bottom extends radially inward from the inner skirt, and the annular bottom has defined thereon a dispensing aperture positioned adjacent to the container opening when the closure is mounted to the container. A sealing member is formed to the annular bottom for closing the dispensing aperture. The outer skirt optionally includes a hingedly flexible flap having one or more gussets dimensioned to cooperate with the anti-rotation structure of a neck finish.
