Abstract: A locking system featuring a movable pin which is selectively operative to lock a blender jar into its holder when the entire jar assembly is positioned on a console or the like for performing a blending operation; otherwise the pin stays in an appropriate position such that the blender jar can be screwed into its holder without hindrance.

Abstract: To facilitate the cleaning of a can opener cutter, the pivoted handle on which it is mounted is arranged for easy removal. The shaft on which the handle is pivoted has an undercut section. A keeper edge mates with the undercut section of the shaft to restrain axial motion of the shaft without inhibiting rotational motion. The inner end of the shaft cams the keeper aside to permit assembly. Although a gravity system could be used, the keeper is normally spring biased towards engagement with the undercut section of the shaft. The keeper and biasing element may constitute a single element. When a spring biased keeper is used, the shaft has a chordal segment removed between the inner end and the undercut section. Thus when the shaft is in a predetermined angular orientation, with respect to the keeper, the handle may be removed without camming the keeper aside.
