ABSTRACT:
A pitcher or similar container of generally cylindrical shape having a closure member for the open upper end of the container, a tubular housing extending axially of the container and mounted in the closure element for rotary and axial movements therein, and an axial shaft mounted in the housing for axial movements with the housing and for rotation relative to the housing. A generally disk-like impeller is mounted on the lower end of the shaft. The tubular housing and closure member have portions that cooperate to limit upward movement of the impeller from the bottom of the container to various levels above the container bottom. Retainer members operate to confine solids below a given liquid level in the container and to limit access of outside air to liquid in the container.
