ABSTRACT:
A blender has a container shaped in an oblong cross-section with the opposite ends of semi-circular shape and parallel straight walls inbetween these ends. The rotary cutter is positioned at the center at one of the semi-circular ends giving the container an off-center heavier side. The power base on which the container sits provides a telescoping tower to house an electrical interlock safety switch at its upper end which is engaged by an element on the container cover so that only when the cover is fully on the container can the blender be activated.
