Abstract
A drop and stream dispensing closure is provided for use on a container. The closure includes a closure structure for being mounted to the container, and the closure structure defines a dispensing opening and a vent opening. A cover is provided on the closure structure and includes sealing plugs for sealing both the vent and dispensing openings. The cover may be moved to an orientation in which the dispensing opening is open but the vent opening is closed. The cover may also be moved to a fully open orientation wherein both the vent opening and dispensing opening are open.
