ABSTRACT:
A seal assembly for bottles or flasks includes a neck member having a generally elongated hollow configuration adapted to non-rotatably fit about the exterior of a bottle or flask. A generally hollow cylindrical intermediate member has a portion which fits within the neck member and cooperates therewith to prevent relative rotation therebetween. The intermediate member has on the interior thereof a device to cooperate with the neck of the bottle or flask to prevent relative longitudinal movement therebetween. The intermediate member has at the upper end thereof a dispensing opening adapted to align and cooperate with the opening in the neck of the bottle or flask. A stopper member has a closed upper end and an open lower end and threads onto the exterior of the intermediate member such that the closed upper end of the stopper member blocks the dispensing opening of the intermediate member.
