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.

Abstract: A cap assembly for use with a centrifuge container includes a stopper (plug) member to provide a fluid-tight seal of an open end of the container. The stopper member includes a channel therethrough. A lid receives the combination of a stopper fitted into the open end of the container. Depending portions on the underside of the lid press upon the stopper to ensure a reliable seal of the container. In addition, the depending portions are adapted to close off an opening of the channel when the lid and stopper are assembled. Removal of the lid opens the channel allowing air to flow into the container, and in this way any vacuum that develops in the container during a centrifugation run is released by such action.
