ABSTRACT:
A cover for plastic pails having a dispensing closure adjacent the cover periphery which allows unimpeded flow of liquid from the pail. An anti-glug vent device is integrally molded in the cover diametrically opposite from the dispensing closure to permit surge free, controlled pouring. A vent panel is disposed in the central top wall of the cover bounded by a cutting zone of reduced cross section and a hinge connection to the cover. An axially disposed actuating lever extends upwardly from the central area of the vent panel. To activate the vent for smooth pouring, the cutting zone is cut with a knife or punctured with a screw driver allowing the vent to open by pushing the actuating lever away from the cutting zone causing the vent panel to pivot about the hinge connection. To reclose the vent, the pivoting action on the actuating lever is reversed causing the cutting zone on the vent panel to become frictionally engaged within the resulting opening in the pail cover.
