ABSTRACT:
There is provided a beverage pitcher in which is mounted a stirrer device for stirring or agitating the contents of the pitcher. The stirrer device includes a plurality of axially spaced vane lobes which are substantially equiangularly spaced about a longitudinal axis. The maximum radial extent of the vane lobes from the lognitudinal axis decreases in the direction from the lower end to the upper end of the plurality of vane lobes, so that during operative rotation of the vane lobes the stirring or agitating effect is at a minimum at the maximum upper level of the contents of the pitcher where only a minimum stirring or agitating effect is required and where substantial stirring or agitation is undesirable.
