Abstract
Abstract A juice container and stirrer comprising a container having a bottom wall, side wall and open upper end and a removable cover for the open end. A shaft is rotatably supported on the cover such that one portion of the shaft extends exteriorly of the container and another portion of the shaft extends internally substantially throughout the height of the container. A handle is provided on the outer end portion of the shaft for gripping and rotating the shaft. A helical vane extends radially outwardly along the portion of the shaft extending within the container. The helical vane has a cross section which includes a radially extending portion and wall adjacent the periphery of the radially extending portion extending axially toward the cover.
