A combination pitcher and mixing subassembly is described that incorporates a mixing head which is longitudinally reciprocally movable within the pitcher. The combination is particularly well suited for use with pitchers that are not cross-sectionally circular, such as pitchers that are elliptical or that have parallel; elongated side walls with semi-circular ends. The mixing head has a peripheral region which generally conforms to the internal bottom configuration of the pitcher. The mixing head has a plurality of straight, elongated vanes that extend across the mixing head in parallel, spaced, diagonal relationship to each other with the vanes on one side of the mixing head shaft being inclined at an opposite angle relative to those on the other side of the shaft. Preferably, the mixing head also has a plurality of vertically oriented, spaced, parallel baffle plates that extend across the mixing head perpendicularly relative to the vanes and that join the vanes at all locations of cross-over.

[ What is claimed is:] [17.]17. A mixing pitcher comprising:a pitcher having side walls, a closed bottom, and an upwardly opening mouth; anda mixing subassembly including:a lid, engageable with the mouth, having a central channel therethrough;a shaft extending through the central channel and reciprocally movable longitudinally relative to the lid; anda mixing head fixed to the shaft and receivable in the pitcher adjacent the side walls and movable between proximate the mouth and proximate the bottom and including a first plurality of vanes on one side of the shaft and a second plurality of vanes on an opposite side of the shaft, the vanes of the first plurality being inclined at a first angle relative to the shaft, and the vanes of the second plurality being inclined at a second angle relative to the shaft, the first and second angles being opposite in inclination;such that during movement of the mixing head in the pitcher in one direction, liquid in the pitcher that moves through the mixing head is angularly deflected by the first and the second pluralities of vanes toward a middle region of the pitcher, while during movement of the mixing head in the pitcher in an opposite direction, liquid in the pitcher that moves through the mixing head is angularly deflected by the first and the second pluralities of vanes towards opposed side regions of the pitcher, thereby producing mixing in the pitcher.
