ABSTRACT:
A vented closure for a liquid container which will not freely pour includes a cap movable between open and closed positions relative to a base collar. The movable cap can be slidable to form a push-pull type closure, or can be rotatable to form a flip-type closure. In an open position, a primary fluid passageway extends through the closure to one or more dispensing opening. One or more air vents of small size are located in the base collar at positions spaced within predetermined ranges of offsets from the dispensing openings. A divider or barrier is located to create a secondary fluid passageway to convey liquid directly into contact with the air vents which can self-seal by surface tension of the liquid and to convey air bubbles through the liquid when the container is tilted. Overlapping portions of the movable cap can protect the vent apertures and/or the dispensing aperture structure.
