Abstract
A resealable push-pull pour spout closure having an annular secondary closure with a central opening through which a plug is adapted to engage to close a container. The central opening is defined by an annular wall having at least one internally extending annular flange. The diameter of the central opening is substantially the same as that of the plug. The plug takes the form of a circular closure disk having an integrally molded depending annular skirt projecting from the periphery of the disk that attaches to angularly extending legs that connect the plug to the spout thereby defining a hollow cavity for the plug interior and increasing the structural flexibility of the plug. The annular seal flange projects radially into opening for form fitting engagement with the plug to substantially eliminate any leakage when the plug is positioned in the central opening.
