Abstract
A dispensing closure system is provided for a container having an opening through which the contents of the container are dispensed. A unitary operating structure is mounted on one side of the opening and includes first and second arms connected together by an integral hinge at adjacent ends of the arms. The opposite ends of the arms are secured to the container at spaced apart pivots. The arms and the hinge are constructed and arranged to permit the arms and the hinge to be moved between a first stable position with the hinge disposed outside a line passing through the spaced apart pivots and a second stable position with the hinge disposed inside the line. A closure member is fixed to one of the arms for pivotal movement between a first position closing the opening when the arms and the hinge are in the first stable position, and a second position spaced outwardly of the opening when the arms and the hinge are in the second stable position. Therefore, the closure member is opened by pushing inwardly on the arms of the operating structure in a direction opposite the opening direction of the closure member.
