ABSTRACT:
A single piece push-pull dispenser for sealing water, juice, detergent containers and the like is provided. The push-pull dispenser has a tubular skirt sized to longitudinally adjustably engage the exterior sidewall of a container neck, and a cylindrical plug disposed within the tubular skirt, sized to engage and seal the mouth of the container neck. The outside perimeter of the cylindrical plug and the inside wall of the tubular skirt are spaced, defining an annular orifice. The cylindrical plug is connected to the tubular skirt by at least one spoke connector which bridges the annular orifice. The push-pull dispenser is longitudinally adjustable along the container neck so that in its lower, closed position, the cylindrical plus seals the container neck. In an upper, open position, the cylindrical plug disengages and unseals the neck permitting the contents to flow through the annular orfice.
