  • Patent number: 6029866
    Abstract: A dispensing structure is provided for an opening to a container. The dispensing structure includes a body for extending from the container around the opening. The dispensing structure defines a discharge aperture communicating with the container opening. An actuator, which defines a pivot axis, is pivotally mounted on the body for occluding flow from the container through the discharge aperture when the actuator is in a closed position and permitting flow from the container when force is applied to the actuator to tilt the actuator to an open position. The actuator includes a first, generally rigid piece which is molded from a material and which defines a force-receiving region on one side of the pivot axis. The actuator includes a second piece which is molded from a material onto the first, rigid, force-receiving region and is bonded to the first, rigid piece to define a finger pad against which a finger may be pressed to tilt the actuator to the open position.
